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.

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.

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.

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.

Infants Exposed To Homelessness: Health, Health Care Use, And Health Spending From Birth To Age Six.

Homeless infants are known to have poor birth outcomes, but the longitudinal impact of homelessness on health, health care use, and health spending during the early years of life has received little attention. Linking Massachusetts emergency shelter enrollment records for the period 2008-15 with Medicaid claims, we compared 5,762 infants who experienced a homeless episode with a group of 5,553 infants matched on sex, race/ethnicity, location, and birth month. Infants born during a period of unstable housing resulting in homelessness had higher rates of low birthweight, respiratory problems, fever, and other common conditions; longer neonatal intensive care unit stays; more emergency department visits; and higher annual spending. Differences in most health conditions persisted for two to three years. Asthma diagnoses, emergency department visits, and spending were significantly higher through age six. While screening and access to health care can be improved for homeless infants, long-term solutions require a broader focus on housing and income.

Mitral Valve Repair Versus Replacement in Elderly With Degenerative Disease: Analysis of the STS Adult Cardiac Surgery Database.

BACKGROUND: It has been postulated that mitral valve repair in the elderly does not confer short-term benefits over mitral valve replacement with complete preservation of the chordal apparatus. Our purpose was to test this hypothesis using data from The Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD). METHODS: Patients aged 70 years or more undergoing primary isolated elective mitral valve repair or mitral valve replacement for degenerative disease were obtained from the STS ACSD versions 2.73 and 2.81. Patients with a concomitant tricuspid procedure, atrial fibrillation surgery, or atrial septal defect/patent foramen ovale repair were included. The two treatment groups were further stratified by age in years (70 to 74, 75 to 79, and 80 or more). Adjusted 30-day mortality rates were analyzed by mitral procedure and chordal preservation strategy. RESULTS: The study included 12,043 patients, of whom 71% underwent mitral valve repair. Observed 30-day mortality after repair was lower than after replacement (2.2% versus 4.8%, respectively; p < 0.0001). Using repair as reference, adjusted operative mortality was higher for replacement in the overall cohort (odds ratio 1.83, 95% confidence interval: 1.45 to 2.31). There was no significant difference in mortality between complete versus partial chordal preservation in repair (odds ratio 1.24, 95% confidence interval: 0.80 to 1.93). Mitral valve replacement with chordal preservation remained inferior to repair (odds ratio 1.66, 95% confidence interval: 1.28 to 2.14). The failed repair rate was 7.9%, with a 30-day mortality of 6%. CONCLUSIONS: In patients aged 70 years or more, degenerative mitral repair was associated with lower operative mortality compared with replacement, irrespective of chordal preservation strategy. Failed repairs reduced this short-term benefit compared with chordal-sparing replacement as evidenced by the similar operative mortality on an intention to treat analysis.

Homelessness Contributes To Pregnancy Complications.

Homelessness during pregnancy poses significant health risks for mothers and infants. As health care providers increase their emphasis on social determinants of health, it is important to understand how unstable housing contributes to complications during pregnancy. We linked data about emergency shelter enrollees with Massachusetts Medicaid claims for the period January 1, 2008-June 30, 2015 to compare health care use and pregnancy complications for 9,124 women who used emergency shelter with those for 8,757 similar women who did not. Rates of mental illness and substance use disorders were significantly higher among homeless women. Adjusted odds of having nine pregnancy complications were also significantly higher for homeless women and remained substantially unchanged after we adjusted for behavioral health disorders. Emergency shelter users also had fewer ambulatory care visits and more months without billable care and were more likely to visit an emergency department. Homelessness and behavioral health disorders appear to be independent factors contributing to pregnancy complications and should be addressed simultaneously.

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.

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.

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.

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.

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.

Outpatient beta-blockers and survival from sepsis: Results from a national cohort of Medicare beneficiaries.

BACKGROUND: Elderly Americans suffer increased mortality from sepsis. Given that beta-blockers have been shown to be cardioprotective in critical care, we investigated outpatient beta-blocker prescriptions and mortality among Medicare beneficiaries admitted for sepsis. METHODS: We queried a 5% random sample of Medicare beneficiaries for patients admitted with sepsis. We used in-hospital and outpatient prescription drug claims to compare in-hospital and 30-day mortality based on pre-admission beta-blocker prescription and class of beta-blocker prescribed using univariate tests of comparison and multivariable logistic regression models and another class of medications for control. RESULTS: Outpatient beta-blocker prescription was associated with a statistically significant decrease in in-hospital and 30-day mortality. In multivariable modeling, beta-blocker prescription was associated with 31% decrease in in-hospital mortality and 41% decrease in 30-day mortality. Both cardioselective and non-selective beta-blockers conferred mortality benefit. CONCLUSIONS: Our data suggests that there may be a role for preadmission beta-blockers in reducing sepsis-related mortality.

Diffusion of technology: Trends in robotic-assisted colorectal surgery.

Following FDA approval, robotic-assisted colorectal surgery (RACS) has increased in prevalence. We aimed to identify trends in utilization and patient characteristics of RACS in the United States using the University HealthSystem Consortium database between October 2011-September 2015. Outcome measures were number and percentage of procedures performed with robotic-assistance. 7100 patients were identified. The most common procedures were low anterior resection, sigmoid colectomy, abdominoperineal resection, right colectomy, rectopexy, left colectomy, and total colectomy. There was a 158% increase in RACS procedures. As a percentage of all approaches, RACS increased from 2.6% to 6.6%. The number of centers performing RACS increased from 105 to 140. Over the study period, the complexity of patients increased, with the percentage of patients with ≥3 comorbidities rising from 18% to 24% (p = 0.03) and patients with a moderate severity of illness score increasing from 35% to 41% (p = 0.04). RACS has expanded significantly in volume, number of centers, and patient selection. Further studies evaluating outcomes and cost of RACS are required to determine whether these increases are justified by improved clinical outcomes.
