Survivorship care planning, quality of life, and confidence to transition to survivorship: A randomized controlled trial with women ending treatment for breast cancer.

PURPOSE: The Polaris Oncology Survivorship Transition (POST) system is a computer-based program that integrates information from the electronic health record, oncology team, and the patient to produce a personalized Survivorship Care Plan. The purpose of this study was to compare the POST to treatment as usual on confidence, quality of life, and interest in mental health referrals in women ending treatment for breast cancer. SAMPLE: Two hundred women (100 POST, 100 treatment as usual) ending treatment for breast cancer were enrolled in a randomized controlled trial. DESIGN: Women randomized to the POST condition received a personalized care plan during a baseline/intervention appointment. At enrollment and baseline/intervention, a number of outcomes were examined in this study, including confidence to enter survivorship measured by the Confidence in Survivorship Index (CSI) and Quality of Life (QOL). One, three, and six month follow up assessments were also conducted. FINDINGS: Treatment groups did not differ in terms of QOL scores at any time points. Mean CSI scores were statistically different between POST and treatment as usual at baseline for the total CSI score and both subscales, but only for confidence in knowledge about prevention and treatment at the 1-month follow-up. All significant differences were in favor of the POST intervention as mean CSI scores were higher for participants who received the POST intervention as opposed to treatment as usual. These findings disappeared at the 3 and 6 month follow up assessments. Finally, patients who received the POST intervention were twice as likely to request mental health/social services referrals compared to women who received treatment as usual. IMPLICATIONS: Oncologists may use the POST to build personalized care plans for women ending treatment for cancer, which may enhance patients' confidence in the short term as well as encourage use of mental health resources.

Not All Discharge Settings Are Created Equal: Thirty-Day Readmission Risk after Elective Colorectal Surgery.

BACKGROUND: Discharge to nonhome settings after colorectal resection may increase risk of hospital readmission. OBJECTIVE: The purpose of this study was to determine the impact of various discharge dispositions on 30-day readmission after adjusting for confounding demographic and clinical factors. DESIGN: This was a retrospective cohort study. SETTINGS: Data were obtained from the University HealthSystem Consortium (2011-2015). PATIENTS: Adults who underwent elective colorectal resection were included. MAIN OUTCOME MEASURES: Thirty-day hospital readmission risk was measured. RESULTS: The mean age of the study population (n = 97,455) was 58 years; half were men and 78% were white. Seventy percent were discharged home routinely (home without service), 24% to home with organized health services, 5% to skilled nursing facility, 1% to rehabilitation facility, and <1% to long-term care hospital. Overall rate of readmission was 12%; 9% from home without service, 16% from home with organized home health services, 19% from skilled nursing facility, 34% from rehabilitation facility, and 22% from long-term care hospital (p < 0.001). Patients with an intensive care unit stay, more postoperative complications, and longer hospitalization stay were more likely to be discharged to home with organized home health services or to a facility (p < 0.001). Discharge to home with organized home health services, skilled nursing facility, or rehabilitation facility increased multivariable-adjusted readmission risk by 30% (OR = 1.3 (95% CI, 1.3-1.6)), 60% (OR = 1.6 (95% CI, 1.5-1.8)), or 200% (OR = 3.0 (95% CI, 2.5-3.6)). Discharge to long-term care hospital was not associated with higher adjusted readmission risk (OR = 1.2 (95% CI, 0.9-1.6)), despite this group having the highest comorbidity and postoperative complications. Among patients readmitted within 30 days, median time to readmission was significantly different among home without service (n = 7), home with organized home health services (n = 8), skilled nursing facility (n = 8), rehabilitation facility (n = 9), and long-term care hospital (n = 12; p < 0.001). LIMITATIONS: This study was limited by its retrospective nature. CONCLUSIONS: Discharge to home with organized home health services, skilled nursing facility, or rehabilitation facility, but not long-term care hospital, is associated with increased adjusted risk of readmission compared with routine home discharge. Potential targets to decrease readmission include improving transition of care at discharge, improving quality of care after discharge, and improving facility resources.

NO TODAS LAS CONFIGURACIONES DE ALTA SON IGUALES: RIESGOS DE READMISIÓN A 30 DÍAS DESPUÉS DE CIRUGÍA COLORRECTAL ELECTIVA: El alta hospitalaria hacia el domicilio luego de una resección colorrectal puede aumentar el riesgo de readmisión.Determinar el impacto de varias configuraciones diferentes de alta en la readmisión a 30 días luego de ajustar factores demográficos y clínicos.Estudio de cohortes retrospectivo.Los datos se obtuvieron del Consorcio del Sistema de Salud Universitaria (2011-2015).Todos aquellos adultos que se sometieron a una resección colorrectal electiva.Los riesgos de readmisión hospitalaria a 30 días.La edad media de la población estudiada (n = 97,455) fué de 58 años; la mitad eran hombres y un 78% eran blancos. El 70% fueron dados de alta de manera rutinaria (a domicilio sin servicios complementarios), 24% alta a domicilio con servicios de salud organizados, 5% alta hacia un centro con cuidados de enfermería especializada, 1% alta hacia un centro de rehabilitación y <1% alta hacia un hospital con atención a largo plazo. La tasa global de readmisión fué del 12%; nueve por ciento desde domicilios sin servicios complementarios, 16% desde domicilios con servicios de salud organizados, 19% desde un centro de enfermería especializada, 34% desde el centro de rehabilitación y 22% desde un hospital con atención a largo plazo (p <0.001). Los pacientes con estadías en Unidad de Cuidados Intensivos, con más complicaciones postoperatorias y con una hospitalización prolongada tenían más probabilidades de ser dados de alta hacia un domicilio con servicios de salud organizados o hacia un centro de rehabilitación (p <0,001). El alta hospitalaria con servicios organizados de atención médica domiciliaria, centros de enfermería especializada o centros de rehabilitación aumentaron el riesgo de readmisión ajustada de múltiples variables en un 30% (OR 1.3, IC 95% 1.3-1.6), 60% (OR 1.6, IC 95% 1.5-1.8), o 200% (OR 3.0, IC 95% 2.5-3.6), respectivamente. El alta hospitalaria a largo plazo no fué asociada con un mayor riesgo de readmisión ajustada (OR 1.2, IC 95% 0.9-1.6), no obstante que este grupo fué el que tuvo las mayores comorbilidades y complicaciones postoperatorias. Entre los pacientes readmitidos dentro de los 30 días, la mediana del tiempo hasta el reingreso fue significativamente diferente entre el domicilio sin servicios complementarios (7), domicilio con servicios de salud organizados (8), el centro de cuidados de enfermería especializada (8), centros de rehabilitación (9) y hospitales con atención a largo plazo (12) (p <0,001).Naturaleza retrospectiva del presente estudio.El alta hospitalaria con servicios de salud domiciliarios organizados, hacia centros de enfermería especializada o hacia centros de rehabilitación se asocian con un mayor riesgo ajustado de readmisión en comparación con el alta domiciliaria de rutina y los hospitales con atención a largo plazo. Los objetivos potenciales para disminuir la readmisión incluyen mejorar la transición de la atención al momento del alta, mejorar la calidad de la atención después del alta y mejorar las diferentes facilidades para los pacientes.

Assessment of the Accuracy and Reliability of Vascular Surgery Quality Metrics.

BACKGROUND: Health care quality metrics are crucial to medical institutions, payers, and patients. Obtaining current and reliable quality data is challenging, as publicly reported databases lag by several years. Vizient Clinical Data Base (previously University Health Consortium) is utilized by over 5,000 academic and community medical centers to benchmark health care metrics with results based on predetermined Vizient service lines. We sought to assess the accuracy and reliability of vascular surgery service line metrics, as determined by Vizient. METHODS: Vizient utilizes encounter data submitted by participating medical centers and generates a diverse array of health care metrics ranging from mortality to costs. All inpatient cases captured by Vizient under the vascular surgery service line were identified at the University of Massachusetts Medical Center (fiscal year 2016). Each case within the service line was reviewed and categorized as "vascular" or "nonvascular" based on care provided by UMass vascular surgery faculty: vascular = vascular surgery was integral part of care, nonvascular = vascular surgery had minimal or no involvement. Statistical analysis comparing length of stay (LOS), cost, readmission, mortality, and complication rates between vascular and nonvascular cohorts was performed. All inpatient cases discharged by a vascular surgeon National Provider Identifier number were also reviewed and categorized according to Vizient service lines. RESULTS: Vizient's vascular surgery service line identified 696 cases, of which 556 (80%) were vascular and 140 (20%) were nonvascular. When comparing these 2 cohorts, vascular cases had a significantly lower LOS (3.4 vs. 8.7 days; P < 0.0001), cost ($8,535 vs. $16,498; P < 0.0001), and complication rate (6.5% vs. 18%; P < 0.0001) than nonvascular. Mortality was also lower (1.6% vs. 5.7%; P < 0.01), but after risk-adjustment, this difference was not significant. When discharging vascular surgeon National Provider Identifier was used to identify vascular surgery cases, only 69% of these cases were placed within the vascular surgery service line. CONCLUSIONS: Health care quality metrics play an important role for all stakeholders but obtaining accurate and reliable data to implement improvements is challenging. In this single institution experience, inpatient cases that were not under the direction or care of a vascular surgeon resulted in significantly negative impacts on LOS, cost, complication rate, and mortality to the vascular surgery service line, as defined by a national clinical database. Therefore, clinicians must understand the data abstracting and reporting process before implementing effective strategic plans.

Hyperchloremia, not Concomitant Hypernatremia, Independently Predicts Early Mortality in Critically Ill Moderate-Severe Traumatic Brain Injury Patients.

BACKGROUND: Hypernatremia has been associated with mortality in neurocritically ill patients, with and without traumatic brain injury (TBI). These studies, however, lack concomitant adjustment for hyperchloremia as a physiologically co-occurring finding despite the associations with hyperchloremia and worse outcomes after trauma, sepsis, and intracerebral hemorrhage. The objective of our study was to examine the association of concomitant hypernatremia and hyperchloremia with in-hospital mortality in moderate-severe TBI (msTBI) patients. METHODS: We retrospectively analyzed prospectively collected data from the OPTIMISM-study and included all msTBI patients consecutively enrolled between 11/2009 and 1/2017. Time-weighted average (TWA) sodium and chloride values were calculated for all patients to examine the unadjusted mortality rates associated with the burden of hypernatremia and hyperchloremia over the entire duration of the intensive care unit stay. Multivariable logistic regression modeling predicting in-hospital mortality adjusted for validated confounders of msTBI mortality was applied to evaluate the concomitant effects of hypernatremia and hyperchloremia. Internal bootstrap validation was performed. RESULTS: Of the 458 patients included for analysis, 202 (44%) died during the index hospitalization. Fifty-five patients (12%) were excluded due to missing data. Unadjusted mortality rates were nearly linearly increasing for both TWA sodium and TWA chloride, and were highest for patients with a TWA sodium > 160 mmol/L (100% mortality) and TWA chloride > 125 mmol/L (94% mortality). When evaluated separately in the multivariable analysis, TWA sodium (per 10 mmol/L change: adjusted OR 4.0 [95% CI 2.1-7.5]) and TWA chloride (per 10 mmol/L change: adjusted OR 3.9 [95% CI 2.2-7.1]) independently predicted in-hospital mortality. When evaluated in combination, TWA chloride remained independently associated with in-hospital mortality (per 10 mmol/L change: adjusted OR 2.9 [95% CI 1.1-7.8]), while this association was no longer observed with TWA sodium values (per 10 mmol/L change: adjusted OR 1.5 [95% CI 0.51-4.4]). CONCLUSIONS: When concomitantly adjusting for the burden of hyperchloremia and hypernatremia, only hyperchloremia was independently associated with in-hospital mortality in our msTBI cohort. Pending validation, our findings may provide the rationale for future studies with targeted interventions to reduce hyperchloremia and improve outcomes in msTBI patients.

Survival prediction in patients with chronic limb-threatening ischemia who undergo infrainguinal revascularization.

OBJECTIVE: Accurate survival prediction critically influences decision-making in caring for patients with chronic limb-threatening ischemia (CLTI). The Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial demonstrated that in patients who survived >2 years, there was a significant advantage to infrainguinal bypass compared with endovascular intervention, which increased with time. Validated survival models for patients with CLTI are lacking. METHODS: The Vascular Quality Initiative was interrogated for patients who underwent infrainguinal bypass or endovascular intervention for CLTI (January 2003-February 2017). Cox survival models were generated using only preoperative variables. Survival at 30 days, 2 years, and 5 years was modeled separately. Patients were defined as low risk (30-day survival >97% and 2-year survival >70%), medium risk (30-day survival 95%-97% or 2-year survival 50%-70%), and high-risk (30-day survival <95% or 2-year survival <50%). RESULTS: Among 38,470 unique CLTI patients, 63% (n = 24,214) underwent endovascular intervention and 37% (n = 14,256) underwent infrainguinal bypass. Kaplan-Meier estimates of overall survival at 30 days, 2 years, and 5 years were 98%, 81%, and 69%, respectively. The proportion of patients in the low-, medium-, and high-risk groups was 84%, 10%, and 6.5%, respectively. Patients in the low-risk group were significantly less likely to undergo endovascular intervention compared with those in the high-risk group (low risk, 59% endovascular; high risk, 75% endovascular; P < .0001). Independent predictors of death were similar in all three models, with greatest magnitude of effect associated with age >80 years, oxygen-dependent chronic obstructive pulmonary disease, stage 5 chronic kidney disease, and bedbound status. The C index for the 30-day model, 2-year model, and 5-year model was 0.76, 0.72, and 0.71, respectively. Procedure type (open or endovascular) was not significant in any models and did not have an impact on C indices. CONCLUSIONS: These survival prediction models, derived from a large U.S. cohort of patients who underwent revascularization for CLTI, demonstrated good performance and should be validated. Most CLTI patients considered candidates for limb salvage were of average perioperative risk and were predicted to survive beyond 2 years. These models can differentiate patients into low-, medium-, and high-risk groups to facilitate evidence-based revascularization recommendations that are consistent with current treatment guidelines.

Impact of the "Weekend Effect" for Hospital Discharges on Readmissions After Elective Colectomy.

BACKGROUND: Hospital readmissions after elective colectomy are costly and potentially preventable. It is unknown whether hospital discharge on a weekend impacts readmission risk. OBJECTIVE: This study aimed to use a national database to determine whether discharge on a weekend versus weekday impacts the risk of readmission, and to determine what discharge-related factors impact this risk. DESIGN: This investigation is a retrospective cohort study. SETTINGS: Data were derived from the University HealthSystem Consortium, PATIENTS:: Adults who underwent elective colectomy from 2011 to 2015 were included. MAIN OUTCOME MEASURES: The primary outcome measured was the 30-day hospital readmission rate. RESULTS: Of the 76,031 patients who survived the index hospitalization, the mean age of the study population was 58 years; half were men and more than 75% were white. Overall, 20,829 (27%) were discharged on the weekend, and the remaining 55,202 (73%) were discharged on weekdays. The overall 30-day readmission rate was 10.5%; 8.9% for those discharged on the weekend vs 11.1% for those discharged during the weekday (unadjusted OR, 0.78; 95% CI, 0.74-0.83). The adjusted readmission risk was lower for patients discharged home without services (routine, without organized home health service) on a weekend compared with on a weekday (adjusted OR, 0.87; 95% CI, 0.81-0.93; readmission rates, 7.4% vs 8.9%, p < 0.001); however, the combination of weekend discharge and the need for home services increased readmission risk (adjusted OR, 1.39; 95% CI, 1.25-1.55; readmission rate, 16.2% vs 8.9%, p < 0.001). Although patients discharged to rehabilitation and skilled nursing facilities were at an increased risk of readmission compared with those discharged to home, there was no additive increase in risk of readmission for weekend discharge. LIMITATIONS: Data did not capture readmission beyond 30 days or to nonindex hospitals. CONCLUSIONS: Patients discharged on a weekend following elective colectomy were at increased risk of readmission compared with patients discharged on a weekday if they required organized home health services. Further prospective studies are needed to identify areas of intervention to improve the discharge infrastructure. See Video Abstract at http://links.lww.com/DCR/A799.

Survival prediction in patients with chronic limb-threatening ischemia who undergo infrainguinal revascularization.

Analysis of Thirty-Day Readmission after Infrainguinal Bypass.

BACKGROUND: The Vascular Study Group of New England (VSGNE) conducted a pilot study evaluating the feasibility of 30-day data collection in patients undergoing infrainguinal bypass (INFRA) which was subsequently expanded to include a limited number of additional sites within the Vascular Quality Initiative (VQI). The purpose of our study was to use these data to evaluate the incidence of 30-day readmission after infrainguinal bypass. A secondary goal of the study was to perform a critical appraisal of the data elements and definitions in the 30-day dataset. METHODS: All infrainguinal bypass procedures performed during the pilot study period (7/2008 and 4/2016) were identified and merged with a dataset containing the 30-day data. Incidence and types of readmission were assessed. The primary endpoint was 30-day readmission, defined as any hospital readmission within 30 days of index operation; unplanned 30-day readmission was the secondary endpoint. Covariates tested for association with the primary and secondary endpoints included patient demographics, comorbidities, procedural, and postoperative characteristics. Variables significant on univariate screen (P < 0.2) were evaluated with logistic regression to identify independent determinants. RESULTS: Of 9,847 infrainguinal bypass patients, 5,842 (59%) patients were identified with 30-day data, and 907 (16%) were readmitted within 30 days. Of readmissions, 675 (85%) were unplanned. Potentially modifiable independent determinants of any 30-day readmission included 30-day surgical site infection (SSI) (odds ratio [OR]: 10, 95% confidence interval [CI]: 8.2-12, P < 0.0001), postoperative acute kidney injury (OR: 1.7, 95% CI: 1.2-2.5, P = 0.002), and discharge anticoagulation (OR: 1.2, 95% CI: 1.04-1.5; P = 0.02). Predictors of unplanned 30-day readmission were very similar but identified in-hospital major amputation as an additional independent predictor (OR: 2.8, 95% CI: 1.6-4.9, P = 0.0002). CONCLUSIONS: This study demonstrates the interest in, and value of, 30-day data collection in VSGNE/VQI and documents the frequency of readmission after infrainguinal bypass. Readmission within 30 days is strongly associated with SSI, stressing the importance of efforts to decrease this complication. Given that many other predictors are unmodifiable, 30-day readmission is only appropriate as a quality metric if it is risk adjusted using large, real-world datasets such as VQI. Lessons learned from this analysis can be used to select optimal 30-day data elements.

Peripheral atherectomy practice patterns in the United States from the Vascular Quality Initiative.

OBJECTIVE: Peripheral atherectomy has been shown to have technical success in single-arm studies, but clinical advantages over angioplasty and stenting have not been demonstrated, leaving its role unclear. We sought to describe patterns of atherectomy use in a real-world U.S. cohort to understand how it is currently being applied. METHODS: The Vascular Quality Initiative was queried to identify all patients who underwent peripheral vascular intervention from January 2010 to September 2016. Descriptive statistics were performed to analyze demographics of the patients, comorbidities, indication, treatment modalities, and lesion characteristics. The intermittent claudication (IC) and critical limb ischemia (CLI) cohorts were analyzed separately. RESULTS: Of 85,605 limbs treated, treatment indication was IC in 51% (n = 43,506) and CLI in 49% (n = 42,099). Atherectomy was used in 15% (n = 13,092) of cases, equivalently for IC (15%; n = 6674) and CLI (15%; n = 6418). There was regional variation in use of atherectomy, ranging from a low of 0% in one region to a high of 32% in another region. During the study period, there was a significant increase in the proportion of cases that used atherectomy (11% in 2010 vs 18% in 2016; P < .0001). Compared with nonatherectomy cases, those with atherectomy use had higher incidence of prior peripheral vascular intervention (IC, 55% vs 43% [P < .0001]; CLI, 47% vs 41% [P < .0001]), greater mean number of arteries treated (IC, 1.8 vs 1.6 [P < .0001]; CLI, 2.1 vs 1.7 [P < .0001]), and lower proportion of prior leg bypass (IC, 10% vs 14% [P < .0001]; CLI, 11% vs 17% [P < .0001]). There was lower incidence of failure to cross the lesion (IC, 1% vs 4% [P < .0001]; CLI, 4% vs 7% [P < .0001]) but higher incidence of distal embolization (IC, 1.9% vs 0.8% [P < .0001]; CLI, 3.0% vs 1.4% [P < .0001]) and, in the CLI cohort, arterial perforation (1.4% vs 1.0%; P = .01). CONCLUSIONS: Despite a lack of evidence for atherectomy over angioplasty and stenting, its use has increased across the United States from 2010 to 2016. It is applied equally to IC and CLI populations, with no identifiable pattern of comorbidities or lesion characteristics, suggesting that indications are not clearly delineated or agreed on. This study places impetus on further understanding of the optimal role for atherectomy and its long-term clinical benefit in the management of peripheral arterial disease.

Reinterventions after fenestrated or branched endovascular aortic aneurysm repair.

OBJECTIVE: Reinterventions after fenestrated or branched endovascular aneurysm repair (F/B-EVAR) are sometimes necessary to maintain aneurysm exclusion or endograft and target artery patency. These reinterventions are nontrivial, potentially associated with morbidity, mortality, and resource utilization. Whereas rates, types, and outcomes of reintervention after infrarenal EVAR have been well described, they have not been well described for F/B-EVAR. We sought to characterize the morbidity, mortality, and resource utilization due to reinterventions after F/B-EVAR. METHODS: All F/B-EVAR variables collected prospectively through a single-institution, Institutional Review Board-approved registry, which included patients enrolled in a physician-sponsored investigational device exemption trial (G130210), were reviewed (November 2010-December 2016). Reinterventions were defined as any procedure that was aneurysm related, device related, or target artery related. For patients with more than one reintervention, each intervention occurrence was treated as a discrete event. Reintervention type, indication, timing (perioperative, days 0-30; short term, days 31-180; midterm, >180 days), inpatient/outpatient, length of stay, and morbidity/mortality were recorded. Reintervention success was defined as resolution of the indication. RESULTS: Among 123 consecutive F/B-EVARs (mean follow-up, 25 months), 32 patients (25%) underwent 54 reinterventions (one reintervention, 20 (63%) patients; two reinterventions, 6 (19%) patients; three reinterventions, 4 (13%) patients; four reinterventions, 1 (3.1%) patient; and six reinterventions, 1 (3.1%) patient). The most frequent indications were type III endoleaks (n = 15 [28%]), target artery occlusions (n = 7 [13%]), and stenoses (n = 6 [11%]). These were performed in the perioperative, short-term, and midterm time frames 17%, 41%, and 43% of the time, respectively. Reinterventions were percutaneous (67%), inpatient procedures (61%), with median length of stay of 5 days. Of the 32 reintervention patients, 4 experienced access site complications and 4 died <30 days after reintervention (3 were adjudicated as not aneurysm related/not reintervention related). In 31 of 32 (97%) patients, reintervention success was achieved. CONCLUSIONS: Reinterventions after F/B-EVAR were necessary in 26% of patients, most commonly for type III endoleaks and target artery complications. Whereas all but one reintervention was successful, many of these required complex procedures with significant morbidity and mortality. Development of strategies to eliminate type III endoleaks by improving component junction integrity and to ensure target artery primary patency are key next steps in the evolution of F/B-EVAR.

Fenestrated endovascular aortic aneurysm repair using physician-modified endovascular grafts versus company-manufactured devices.

OBJECTIVE: Fenestrated endografts are customized, patient-specific endovascular devices with potential to reduce morbidity and mortality of complex aortic aneurysm repair. With approval from the U.S. Food and Drug Administration, our center began performing fenestrated endovascular aneurysm repair through a physician-sponsored investigational device exemption (IDE #G130210), using both physician-modified endografts (PMEGs) and company-manufactured devices (CMDs). Because these techniques are associated with specific advantages and disadvantages, we sought to investigate differences in outcomes between PMEG and CMD cases. METHODS: A single-institution retrospective review of all fenestrated endovascular aneurysm repairs was performed. The cohort was analyzed by device type (PMEG or CMD) after matching of cases on the basis of (1) number of target vessels intended for treatment, (2) extent of aneurysm, (3) aneurysm diameter, (4) device configuration, and (5) date of operation. Outcomes of ruptures, common iliac artery aneurysms, and aortic arch aneurysms were excluded. Demographics, operative details, perioperative complications, length of stay, and reinterventions were compared. For patients with >1 year of follow-up time, survival, type I or type III endoleak rate, target artery patency, and reintervention rate were estimated using the Kaplan-Meier method. RESULTS: Between November 30, 2010, and July 30, 2016, 82 patients were identified and matched. The cohort included 41 PMEG and 41 CMD patients who underwent repair of 38 juxtarenal (PMEG, 17; CMD, 21; P = .38), 14 pararenal (PMEG, 6; CMD, 8; P = .56), and 30 thoracoabdominal type I to type IV (PMEG, 18; CMD, 12; P = .17) aneurysms. There were significant differences in presentation requiring urgent aneurysm repair (PMEG, 9; CMD, 0; P = .002), total fluoroscopy time (PMEG, 76 minutes; CMD, 61 minutes; P = .02), volume of contrast material used (PMEG, 88 mL; CMD, 70 mL; P = .02), in-operating room to out-of-operating room time (PMEG, 391 minutes; CMD, 319 minutes; P = .001), incision to surgery end time (PMEG, 276 minutes; CMD, 224 minutes; P = .002), and 1-year reintervention rate (PMEG, 37%; CMD, 13%; log-rank P = .04). No differences in perioperative complications, overall length of stay, type I or type III endoleak, or survival were observed between PMEG and CMD. For the entire cohort including both PMEG and CMD, the overall rate of any 30-day postoperative complication was 39%, and the Kaplan-Meier estimate of survival at 1 year was 86%. CONCLUSIONS: In this single-institution experience of fenestrated endovascular aneurysm repair, the primary differences between PMEG and CMD related only to operative metrics and the need for postoperative reinterventions. No statistically significant advantage was found for one approach over the other; we therefore cannot conclude that one approach is better than the other. Both remain viable options that may compare favorably with open repair of complex aortic aneurysms. Further studies are necessary to determine whether this relative equivalence represents a type II error or lack of long-term durability data or whether true equivalence between PMEG and CMD approaches exists.

A physician-led initiative to improve clinical documentation results in improved health care documentation, case mix index, and increased contribution margin.

INTRODUCTION: Clinical documentation is the key determinant of inpatient acuity of illness and payer reimbursement. Every inpatient hospitalization is placed into a diagnosis related group with a relative value based on documented procedures, conditions, comorbidities and complications. The Case Mix Index (CMI) is an average of these diagnosis related groups and directly impacts physician profiling, medical center profiling, reimbursement, and quality reporting. We hypothesize that a focused, physician-led initiative to improve clinical documentation of vascular surgery inpatients results in increased CMI and contribution margin. METHODS: A physician-led coding initiative to educate physicians on the documentation of comorbidities and conditions was initiated with concurrent chart review sessions with coding specialists for 3 months, and then as needed, after the creation of a vascular surgery documentation guide. Clinical documentation and billing for all carotid endarterectomy (CEA) and open infrainguinal procedures (OIPs) performed between January 2013 and July 2016 were stratified into precoding and postcoding initiative groups. Age, duration of stay, direct costs, actual reimbursements, contribution margin (CM), CMI, rate of complication or comorbidity, major complication or comorbidity, severity of illness, and risk of mortality assigned to each discharge were abstracted. Data were compared over time by standardizing Centers for Medicare and Medicaid Services (CMS) values for each diagnosis related group and using a CMS base rate reimbursement. RESULTS: Among 458 CEA admissions, postcoding initiative CEA patients (n = 253) had a significantly higher CMI (1.36 vs 1.25; P = .03), CM ($7859 vs $6650; P = .048), and CMS base rate reimbursement ($8955 vs $8258; P = .03) than precoding initiative CEA patients (n = 205). The proportion of admissions with a documented major complication or comorbidity and complication or comorbidity was significantly higher after the coding initiative (43% vs 27%; P < .01). Among 504 OIPs, postcoding initiative patients (n = 227) had a significantly higher CMI (2.23 vs 2.05; P < .01), actual reimbursement ($23,203 vs $19,909; P < .01), CM ($12,165 vs $8840; P < .01), and CMS base rate reimbursement ($14,649 vs $13,496; P < .01) than precoding initiative patients (n = 277). The proportion of admissions with a documented major complication or comorbidity and complication or comorbidity was significantly higher after the coding initiative (61% vs 43%; P < .01). For both CEA and OIPs, there were no differences in age, duration of stay, total direct costs, or primary insurance status between the precoding and postcoding patient groups. CONCLUSIONS: Accurate and detailed clinical documentation is required for key stakeholders to characterize the acuity of inpatient admissions and ensure appropriate reimbursement; it is also a key component of risk-adjustment methods for assessing quality of care. A physician-led documentation initiative significantly increased CMI and CM.

Health Care Utilization and Expenditures of Homeless Family Members Before and After Emergency Housing.

OBJECTIVES: To describe longitudinal health service utilization and expenditures for homeless family members before and after entering an emergency shelter. METHODS: We linked Massachusetts emergency housing assistance data with Medicaid claims between July 2008 and June 2015, constructing episodes of health care 12 months before and 12 months after families entered a shelter. We modeled emergency department visits, hospital admissions, and expenditures over the 24-month period separately for children and adults. RESULTS: Emergency department visits, hospital admissions, and expenditures rose steadily before shelter entry and declined gradually afterward, ending, in most cases, near the starting point. Infants, pregnant women, and individuals with depression, anxiety, or substance use disorder had significantly higher rates of all outcomes. Many children's emergency department visits were potentially preventable. CONCLUSIONS: Increased service utilization and expenditures begin months before families become homeless and are potentially preventable with early intervention. Infants are at greater risk. Public Health Implications. Early identification and intervention to prevent homeless episodes, focusing on family members with behavioral health disorders, who are pregnant, or who have young children, may save money and improve family health.

Trends in use of the only Food and Drug Administration-approved commercially available fenestrated endovascular aneurysm repair device in the United States.

BACKGROUND: Fenestrated endografts are customized, patient-specific, endovascular devices with potential to significantly reduce morbidity and mortality of short-neck infrarenal and juxtarenal abdominal aortic aneurysm repair. The Zenith fenestrated endovascular graft (ZFEN) for abdominal aortic aneurysms (Cook Medical, Bloomington, Ind), Food and Drug Administration-approved in 2012, remains the only fenestrated device available in the United States. This technology is among the most technically complex catheter-based procedures and, therefore, inherently associated with serious risk for device-related complications. We sought to define patterns of physician and hospital adoption of ZFEN. METHODS: Deidentified datasets containing numbers of physicians trained, orders by physicians and hospitals, and designs (fenestration/scallop configuration) was provided for U.S. ZFEN devices ordered (April 2012-August 2015). We evaluated the number of physicians trained, the number of devices ordered, hospital characteristics, and fenestration/scallop design configurations. Cook Medical assembled the datasets but played no role in study design, analysis, or interpretation of data. RESULTS: Between April 2012 and August 2015, 553 physicians attended formal ZFEN training sessions, 388 (70%) of whom ordered a total of 2669 devices. An increase in orders per month (nine in June 2012 and 91 in August 2015, 911% growth; P < .001) and in number of physicians ordering per month (eight in June 2012 and 62 in August 2015, 675% growth; P < .001) was observed. Teaching hospitals, representing all U.S. regions (Midwest 927, 35%; South 799, 30%; Northeast 547, 20%; West 396, 15%), accounted for 1703 (64%) ZFEN orders. Of 553 trained physicians, 165 (30%) ordered no devices, 116 (21%) ordered 1 device, 144 (26%) ordered 2-5 devices, 61 (11%) ordered 6-10 devices, 39 (7%) ordered 11-20, and 28 (5%) ordered >20 devices. For physicians contributing >6 months of data (n = 336), the average number of devices ordered per year was three (standard deviation, 4); 272 (81%) ordered ≤ 5 devices/year, 15 (4.5%) ordered 11-20 devices/year, and 3 (0.9%) ordered >20 devices/year. Of devices with design details available (2618 of 2669; 98%), most common designs were 2 small fenestrations/1 scallop (1443; 55%), 2 small fenestrations/1 large fenestration (568; 22%), 1 small fenestration/1 scallop (173, 6.6%), and 2 small fenestrations (169; 6.5%). The average number of target vessels incorporated in each design was 2.7/device; 2071 (79%) incorporated three, 398 (15%) incorporated two. CONCLUSIONS: Since 2012, ZFEN has demonstrated a ninefold increase in monthly orders, with 553 physicians trained. Unlike the experience of rapid dissemination seen with infrarenal endografts, only 28 (5%) physicians have ordered >20, whereas 165 (30%) have ordered none, and 272 (81%) ordered ≤ 5 devices/year. Assuming that volume, in general, correlates with outcomes, this adoption pattern raises questions whether fenestrated technology should be regionalized to high-volume centers.

Determinants of Follow-Up Failure in Patients Undergoing Vascular Surgery Procedures.

BACKGROUND: The Vascular Study Group of New England (VSGNE) requires documentation of follow-up for >80% of patients at least 9 months postprocedure. However, many participating groups fall short of this goal. We sought to identify factors independently associated with loss to long-term follow-up (LTF). METHODS: The VSGNE was queried from 2008 to 2012, for all carotid endarterectomy (CEA), endovascular aneurysm repair (EVAR), open abdominal aortic aneurysm repair (OPEN), infrainguinal bypass (INFRA), and suprainguinal bypass (SUPRA) procedures in patients who survived greater than 9 months postprocedure. Our primary endpoint was loss to LTF, with LTF defined as documentation of a phone call or office visit ≥9 months postprocedure. Multivariable logistic regression was used to identify independent predictors of loss to LTF. Covariates included patient and procedural characteristics, and treatment center/physician. Relative contributions of covariates to the model were assessed by evaluation of the relative model Wald chi-squared values. RESULTS: We identified 14,452 procedures (6567 CEA, 2391 EVAR, 3356 INFRA, 979 OPEN, and 1159 SUPRA). Of those, 4669 (32%) were lost to LTF. Rates of loss to LTF varied by center, and ranged from 9.8% to 100%. Independent predictors of loss to LTF were history of coronary artery disease or percutaneous coronary artery intervention (odds ratio [OR] 1.4, 95% confidence interval [CI] 1.1-1.7), procedure type (OPEN, OR 1.4, 95% CI: 1.2-1.7; CEA, OR 1.2, 95% CI: 1.1-1.4; referent, EVAR), and discharge to rehab (OR 1.2, 95% CI: 1.1-1.4; referent, home). Center variation was the strongest determinant of loss to LTF with a model χ2 over 40 times as large as the second strongest determinant. CONCLUSIONS: LTF is central to outcome reporting and is vital to the success of any registry effort. In the VSGNE experience, center variation is the strongest predictor of loss to LTF, outweighing patient and procedural factors. Other predictors of loss to LTF included history of coronary revascularization, procedure type, no prior history of congestive heart failure, and discharge location. High performing centers likely have specific process measures that decrease loss to LTF. As the Society for Vascular Surgery Vascular Quality Initiative continues to roll out nationally, high performing centers in VSGNE should be studied to document and propagate best practices for minimizing loss to LTF.

Examination of Racial Disparities in the Receipt of Minimally Invasive Surgery Among a National Cohort of Adult Patients Undergoing Colorectal Surgery.

BACKGROUND: Racial disparities in outcomes are well described among surgical patients. OBJECTIVE: The purpose of this work was to identify any racial disparities in the receipt of a minimally invasive approach for colorectal surgery. DESIGN: Adults undergoing colorectal surgery were studied using the University HealthSystem Consortium. Univariate and multivariable analyses were used to identify predictors for the receipt of a minimally invasive approach. SETTINGS: The study was conducted at academic hospitals and their affiliates. PATIENTS: Adults ≥18 years of age who underwent surgery for colorectal cancer, diverticular disease, IBD, or benign colorectal tumor between 2008 and 2011 were included. MAIN OUTCOME MEASURES: The receipt of a minimally invasive surgical approach was the main measured outcome. RESULTS: A total of 82,474 adult patients met the study inclusion criteria. Of these, 69,664 (84%) were white, 10,874 (13%) were black, and 1936 (2%) were Asian. Blacks were younger, with higher rates of public insurance and higher comorbidity burden and baseline severity of illness compared with white and Asian patients. Black patients were less likely (adjusted OR = 0.83 (95% CI, 0.79-0.87)) and Asian patients more likely (adjusted OR = 1.34 (95% CI, 1.21-1.49)) than whites to receive minimally invasive surgery. This association did not change with stratification by insurance type (public or private). Black patients had higher rates of intensive care unit admission and nonhome discharge, as well as an increased length of stay compared with white and Asian patients. No differences in complications, readmission, or mortality rates were observed with minimally invasive surgery, but black patients were more likely to be readmitted or to die with open surgery. LIMITATIONS: The study was limited by the retrospective nature of its data. CONCLUSIONS: We identified racial differences in the receipt of a minimally invasive approach for colorectal surgery, regardless of insurance status, as well as improved outcomes for minority races who underwent a minimally invasive technique compared with open surgery. The improved outcomes associated with minimally invasive surgery should prompt efforts to increase rates of its use among black patients.

National variation in preoperative imaging, carotid duplex ultrasound criteria, and threshold for surgery for asymptomatic carotid artery stenosis.

OBJECTIVE: Carotid endarterectomy (CEA) for asymptomatic carotid artery stenosis is among the most common procedures performed in the United States. However, consensus is lacking regarding optimal preoperative imaging, carotid duplex ultrasound criteria, and ultimately, the threshold for surgery. We sought to characterize national variation in preoperative imaging, carotid duplex ultrasound criteria, and threshold for surgery for asymptomatic CEA. METHODS: The Society for Vascular Surgery Vascular Quality Initiative (VQI) database was used to identify all CEA procedures performed for asymptomatic carotid artery stenosis between 2003 and 2014. VQI currently captures 100% of CEA procedures performed at >300 centers by >2000 physicians nationwide. Three analyses were performed to quantify the variation in (1) preoperative imaging, (2) carotid duplex ultrasound criteria, and (3) threshold for surgery. RESULTS: Of 35,695 CEA procedures in 33,488 patients, the study cohort was limited to 19,610 CEA procedures (55%) performed for asymptomatic disease. The preoperative imaging modality used before CEA varied widely, with 57% of patients receiving a single preoperative imaging study (duplex ultrasound imaging, 46%; computed tomography angiography, 7.5%; magnetic resonance angiography, 2.0%; cerebral angiography, 1.3%) and 43% of patients receiving multiple preoperative imaging studies. Of the 16,452 asymptomatic patients (89%) who underwent preoperative duplex ultrasound imaging, there was significant variability between centers in the degree of stenosis (50%-69%, 70%-79%, 80%-99%) designated for a given peak systolic velocity, end diastolic velocity, and internal carotid artery-to-common carotid artery ratio. Although 68% of CEA procedures in asymptomatic patients were performed for an 80% to 99% stenosis, 26% were performed for a 70% to 79% stenosis, and 4.1% were performed for a 50% to 69% stenosis. At the surgeon level, the range in the percentage of CEA procedures performed for a <80% asymptomatic carotid artery stenosis is from 0% to 100%. Similarly, at the center level, institutions range in the percentage of CEA procedures performed for a <80% asymptomatic carotid artery stenosis from 0% to 100%. CONCLUSIONS: Despite CEA being an extremely common procedure, there is widespread variation in the three primary determinants-preoperative imaging, carotid duplex ultrasound criteria, and threshold for surgery-of whether CEA is performed for asymptomatic carotid stenosis. Standardizing the approach to care for asymptomatic carotid artery stenosis will mitigate the significant downstream effects of this variation on health care costs.

Rates of insurance for injured patients before and after health care reform in Massachusetts: a possible case of double jeopardy.

OBJECTIVES: We determined how preinjury insurance status and injury-related outcomes among able-bodied, community-dwelling adults treated at a Level I Trauma Center in central Massachusetts changed after health care reform. METHODS: We compared insurance status at time of injury among non-Medicare-eligible adult Massachusetts residents before (2004-2005) and after (2009-2010) health care reform, adjusted for demographic and injury covariates, and modeled associations between insurance status and trauma outcomes. RESULTS: Among 2148 patients before health care reform and 2477 patients after health care reform, insurance rates increased from 77% to 84% (P < .001). Younger patients, men, minorities, and penetrating trauma victims were less likely to be insured irrespective of time period. Uninsured patients were more likely to be discharged home without services (adjusted odds ratio = 3.46; 95% confidence interval = 2.65, 4.52) compared with insured patients. CONCLUSIONS: Preinjury insurance rates increased for trauma patients after health care reform but remained lower than in the general population. Certain Americans may be in "double jeopardy" of both higher injury incidence and worse outcomes because socioeconomic factors placing them at risk for injury also present barriers to compliance with an individual insurance mandate.

Clinical and financial impact of hospital readmissions after colorectal resection: predictors, outcomes, and costs.

BACKGROUND: After passage of the Affordable Care Act, 30 -day hospital readmissions have come under greater scrutiny. Excess readmissions for certain medical conditions and procedures now result in penalizations on all Medicare reimbursements. OBJECTIVE: The purpose of this work was to define the risk factors, outcomes, and costs of 30-day readmissions after colorectal surgery. DESIGN: Adults undergoing colorectal surgery were studied using data from the University HealthSystem Consortium. Univariate and multivariable analyses were used to identify patient-related risk factors for, and 30-day outcomes of, readmission after colorectal surgery. SETTINGS: This study was conducted at an academic hospital and its affiliates. PATIENTS: Adults ≥18 years of age who underwent colorectal surgery for cancer, diverticular disease, IBD, or benign tumors between 2008 and 2011 were included in this study. MAIN OUTCOME MEASURES: Readmission within 30 days of index discharge was the main outcome measured. RESULTS: A total of 70,484 patients survived the index hospitalization after colorectal surgery; 9632 (13.7%) were readmitted within 30 days of discharge. The strongest independent predictors of readmission were length of stay ≥4 days (OR 1.44; 95% CI 1.32-1.57), stoma (OR 1.54; 95% CI 1.46-1.51), and discharge to skilled nursing (OR 1.62; 95% CI 1.49-1.76) or rehabilitation facility (OR 2.93; 95% CI 2.53-3.40). Of those readmitted, half of the readmissions occurred within 7 days, 13% required the intensive care unit, 6% had a reoperation, and 2% died during the readmission stay. The median combined total direct hospital cost was more than 2 times higher ($26,917 vs $13,817; p < 0.001) for readmitted than for nonreadmitted patients. LIMITATIONS: Follow-up was limited to 30 days after initial discharge. CONCLUSIONS: Readmissions after colorectal resection occur frequently and incur a significant financial burden on the health-care system. Future studies aimed at targeted interventions for high-risk patients may reduce readmissions and curb escalating health-care costs.

Actigraphy: An Adjunctive Method to Measure Irritability in Opioid-Exposed Newborns.

Background and purpose: Conventional measures of withdrawal in newborns with prenatal opioid exposure (POE) rely on nursing assessments, including the subjective judgment of infant irritability. This study investigated limb movement actigraphy as a tool for providing an objective, quantifiable measure of underlying distress. Methods: Correlational analyses compared continuous physiological-detected movement actigraphy and clinical intervallic-scored symptomology (modified Finnegan system) obtained from a control cohort of 37 term neonates with POE studied in their crib in the newborn unit (1-8 days). Results: Infants spent 15% crib time in high movement activity (>100 movements/minute; index irritability) and 38% crib time in low activity (0-5 movements/minute; index calm). There was a significant positive association between actigraphy and Finnegan composite score (r = .28, P = .001) and between actigraphy and subcomponent scores (i.e., central nervous system, gastrointestinal, and metabolic-vasomotor-respiratory). Conclusion: Movement activity via actigraphy captures underlying distress and calm not measured by conventional assessments. Such objective, quantifiable measures can serve to promote equitable assessment and treatment of hospitalized newborns with POE.
