Costs of Care for Operative and Nonoperative Management of Emergency General Surgery Conditions.

OBJECTIVE: Many emergency general surgery (EGS) conditions can be managed operatively or nonoperatively, with outcomes that vary by diagnosis. We hypothesized that operative management would lead to higher in-hospital costs but to cost savings over time. BACKGROUND: EGS conditions account for $28 billion in health care costs in the United States annually. Compared with scheduled surgery, patients who undergo emergency surgery are at increased risk of complications, readmissions, and death, with accompanying costs of care that are up to 50% higher than elective surgery. Our prior work demonstrated that operative management had variable impacts on clinical outcomes depending on the EGS condition. METHODS: This was a nationwide, retrospective study using fee-for-service Medicare claims data. We included patients 65.5 years of age or older with a principal diagnosis for an EGS condition 7/1/2015-6/30/2018. EGS conditions were categorized as: colorectal, general abdominal, hepatopancreaticobiliary (HPB), intestinal obstruction, and upper gastrointestinal. We used near-far matching with a preference-based instrumental variable to adjust for confounding and selection bias. Outcomes included Medicare payments for the index hospitalization and at 30, 90, and 180 days. RESULTS: Of 507,677 patients, 30.6% received an operation. For HPB conditions, costs for operative management were initially higher but became equivalent at 90 and 180 days. For all others, operative management was associated with higher inpatient costs, which persisted, though narrowed, over time. Out-of-pocket costs were nearly equivalent for operative and nonoperative management. CONCLUSIONS: Compared with nonoperative management, costs were higher or equivalent for operative management of EGS conditions through 180 days, which could impact decision-making for clinicians, patients, and health systems in situations where clinical outcomes are similar.

Establishing the Essential Role of Household Extenders for Surgeon Wellbeing.

OBJECTIVE: The aim of this study was to investigate the association between a change in household support during the Covid-19 pandemic and surgeon stress. BACKGROUND: The hours and unpredictability of surgical practice often necessitate the employment of household extenders (eg, child caregivers) to maintain a safe home environment for surgeons and their families. The Covid-19 pandemic destabilized these relationships and provided an opportunity to reflect on the role that household extenders play in a surgical household. METHODS: A multi-institutional telephone survey of surgeons practicing at five geographically diverse academic institutions was conducted (May 15, 2020-June 5, 2020). Surgeons were classified by change in household extenders (HE) during the pandemic (decrease, increase, no change, or none). The primary outcome was self-reported surgeon stress level. Multivariable linear regression was used to examine the relationship between change in HE and surgeon stress, adjusting for training and relationship status, the presence of pets and children in the household, and study site. RESULTS: The majority (182, 54.3%) of surgeons employed HE before the pandemic; 121 (36.1%) reported a decrease in HE during the pandemic, 9 (2.7%) reported an increase, and 52 (15.5%) reported no change. Stress scores varied significantly by change in HE group ( P = 0.016). After controlling for potential confounders, having an increase in HE was associated with a higher stress score (+1.55 points) than having no decrease in HE (P = 0.033), and having a decrease in HE was associated with a higher stress score (+0.96 points) than having no decrease ( P = 0.004). CONCLUSIONS: Household extenders play a vital and complex role in enabling the healthcare workforce to care of the population. Surgeons who experienced a change in household extenders reported the highest stress levels. We suggest that health systems should proactively support surgeons by supporting the household extender workforce.

Health System Structure: An Opportunity to Address Structural Racism and Discrimination.

OBJECTIVE: To examine the role of hub-and-spoke systems as a factor in structural racism and discrimination. BACKGROUND: Health systems are often organized in a "hub-and-spoke" manner to centralize complex surgical care to 1 high-volume hospital. Although the surgical health care disparities are well described across health care systems, it is not known how they seem across a single system's hospitals. METHODS: Adult patients who underwent 1 of 10 general surgery operations in 12 geographically diverse states (2016-2018) were identified using the Healthcare Cost and Utilization Project's State Inpatient Databases. System status was assigned using the American Hospital Association dataset. Hub designation was assigned in 2 ways: (1) the hospital performing the most complex operations (general hub) or (2) the hospital performing the most of each specific operation (procedure-specific hub). Independent multivariable logistic regression was used to evaluate the risk-adjusted odds of treatment at hubs by race and ethnicity. RESULTS: We identified 122,236 patients across 133 hospitals in 43 systems. Most patients were White (73.4%), 14.2% were Black, and 12.4% Hispanic. A smaller proportion of Black and Hispanic patient underwent operations at general hubs compared with White patients (B: 59.6% H: 52.0% W: 62.0%, P <0.001). After adjustment, Black and Hispanic patients were less likely to receive care at hub hospitals relative to White patients for common and complex operations (general hub B: odds ratio: 0.88 CI, 0.85, 0.91 H: OR: 0.82 CI, 0.79, 0.85). CONCLUSIONS: When White, Black, and Hispanic patients seek care at hospital systems, Black and Hispanic patients are less likely to receive treatment at hub hospitals. Given the published advantages of high-volume care, this new finding may highlight an opportunity in the pursuit of health equity.

Variation in Hospital Performance for General Surgery in Younger and Older Adults: A Retrospective Cohort Study.

OBJECTIVE: To compare hospital surgical performance in older and younger patients. SUMMARY BACKGROUND DATA: In-hospital mortality after surgical procedures varies widely between hospitals. Prior studies suggest that failure-to-rescue rates drive this variation for older adults, but the generalizability of these findings to younger patients remains unknown. METHODS: We performed a retrospective cohort study of patients ≥18 years undergoing one of ten common and complex general surgery operations in 16 states using the Healthcare Cost and Utilization Projects State Inpatient Databases (2016-2018). Patients were split into two populations: Medicare ≥65 (older adult) and non-Medicare <65 (younger adult) patients. Hospitals were sorted into quintiles using risk-adjusted in-hospital mortality rates for each age population. Correlations between hospitals in each mortality quintile across age populations were calculated. Complication and failure-to-rescue rates were compared across the highest and lowest mortality quintiles in each age population. RESULTS: We identified 579,582 patients treated in 732 hospitals. The mortality rate was 3.6% among older adults and 0.7% among younger adults. Among older adults, high- relative to low-mortality hospitals had similar complication rates (32.0% vs. 29.8%; P=0.059) and significantly higher failure-to-rescue rates (16.0% vs. 4.0%; P<0.001). Among younger adults, high- relative to low-mortality hospitals had higher complication (15.4% vs. 12.1%; P<0.001) and failure-to-rescue rates (8.3% vs. 0.7%; P<0.001). The correlation between observed-to-expected mortality ratios in each age group was 0.385 (P<0.001). CONCLUSIONS: High surgical mortality rates in younger patients may be driven by both complication and failure-to-rescue rates. There is little overlap between low-mortality hospitals in the older and younger adult populations. Future work must delve into the root causes of this age-based difference in hospital-level surgical outcomes.

Operative and Nonoperative Outcomes of Emergency General Surgery Conditions: An Observational Study Using a Novel Instrumental Variable.

OBJECTIVE: To determine the effect of operative versus nonoperative management of emergency general surgery conditions on short-term and long-term outcomes. BACKGROUND: Many emergency general surgery conditions can be managed either operatively or nonoperatively, but high-quality evidence to guide management decisions is scarce. METHODS: We included 507,677 Medicare patients treated for an emergency general surgery condition between July 1, 2015, and June 30, 2018. Operative management was compared with nonoperative management using a preference-based instrumental variable analysis and near-far matching to minimize selection bias and unmeasured confounding. Outcomes were mortality, complications, and readmissions. RESULTS: For hepatopancreaticobiliary conditions, operative management was associated with lower risk of mortality at 30 days [-2.6% (95% confidence interval: -4.0, -1.3)], 90 days [-4.7% (-6.50, -2.8)], and 180 days [-6.4% (-8.5, -4.2)]. Among 56,582 intestinal obstruction patients, operative management was associated with a higher risk of inpatient mortality [2.8% (0.7, 4.9)] but no significant difference thereafter. For upper gastrointestinal conditions, operative management was associated with a 9.7% higher risk of in-hospital mortality (6.4, 13.1), which increased over time. There was a 6.9% higher risk of inpatient mortality (3.6, 10.2) with operative management for colorectal conditions, which increased over time. For general abdominal conditions, operative management was associated with 12.2% increased risk of inpatient mortality (8.7, 15.8). This effect was attenuated at 30 days [8.5% (3.8, 13.2)] and nonsignificant thereafter. CONCLUSIONS: The effect of operative emergency general surgery management varied across conditions and over time. For colorectal and upper gastrointestinal conditions, outcomes are superior with nonoperative management, whereas surgery is favored for patients with hepatopancreaticobiliary conditions. For obstructions and general abdominal conditions, results were equivalent overall. These findings may support patients, clinicians, and families making these challenging decisions.

Racial and Ethnic Disparities in Appropriate Thyroid Cancer Treatment, Before and After the Release of the 2015 American Thyroid Association Guidelines.

BACKGROUND: The 2015 American Thyroid Association (ATA) guidelines reduced the recommended extent of therapy for low-risk thyroid cancers. Little is known about the impact of these changes on overall treatment patterns and on previously described racial/ethnic disparities in guideline-concordant care. This study aimed to assess trends in thyroid cancer care before and after release of the 2015 guidelines, with particular attention to racial/ethnic disparities. METHODS: Patients with well-differentiated thyroid cancer were identified from the National Cancer Database (2010-2018). An interrupted time series design was used to assess trends in treatment before and after the 2015 guidelines. Appropriateness of surgical and radioactive iodine (RAI) treatment was determined based on the ATA guidelines, and the likelihood of receiving guideline-concordant treatment was compared between racial/ethnic groups. RESULTS: The study identified 309,367 patients (White 74%, Black 8%, Hispanic 9%, Asian 6%). Between 2010 and 2015, the adjusted probability of appropriate surgery was lower for Black (- 2.1%; p < 0.001), Hispanic (- 1.0%; p < 0.001), and Asian (- 2.1%; p < 0.001) patients than for White patients. After 2015, only Hispanic patients had a lower probability of undergoing appropriate surgical therapy (- 2.6%; p = 0.040). Similarly, between 2010 and 2015, the adjusted probability of receiving appropriate RAI therapy was lower for the Hispanic (- 3.6%; p < 0.001) and Asian (- 2.4%; p < 0.001) patients than for White patients. After 2015, the probability of appropriate RAI therapy did not differ between groups. CONCLUSIONS: Between 2010 and 2015, patients from racial/ethnic minority backgrounds were less likely than White patients to receive appropriate surgical and RAI therapy for thyroid cancer. After the 2015 guidelines, racial/ethnic disparities in treatment improved.

Impact of Medicaid expansion on outcomes after abdominal aortic aneurysm repair.

OBJECTIVE: Lack of insurance has been independently associated with an increased risk of in-hospital mortality after abdominal aortic aneurysm repair, possibly due to worse control of comorbidities and delays in diagnosis and treatment. Medicaid expansion has improved insurance rates and access to care, potentially benefiting these patients. We sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair. METHODS: A retrospective analysis of Healthcare Cost and Utilization Project State Inpatient Databases data from 14 states between 2012 and 2018 was conducted. The sample was restricted to first-record abdominal aortic aneurysm repairs in adults under age 65 in states that expanded Medicaid on January 1, 2014 (Medicaid expansion group) or had not expanded before December 31, 2018 (non-expansion group). The Medicaid expansion and non-expansion groups were compared between pre-expansion (2012-2013) and post-expansion (2014-2018) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors, open vs endovascular repair, and standard errors clustered by state. Our primary outcome was in-hospital mortality. Outcomes were stratified by insurance type. RESULTS: We examined 8995 patients undergoing abdominal aortic aneurysm repair, including 3789 (42.1%) in non-expansion states and 5206 (57.9%) in Medicaid expansion states. Rates of Medicaid insurance were unchanged in non-expansion states but increased in Medicaid expansion states post-expansion (non-expansion: 10.9% to 9.8%; P = .346; expansion: 9.7% to 19.7%; P < .001). One in 10 patients from both non-expansion and Medicaid expansion states presented with ruptured aneurysms, which did not change over time. Rates of open repair decreased in both non-expansion and Medicaid expansion states over time (non-expansion: 25.1% to 19.2%; P < .001; expansion: 25.2% to 18.4%; P < .001). On adjusted difference-in-differences analysis between expansion and non-expansion states pre-to post-expansion, Medicaid expansion was associated with a 1.02% absolute reduction in in-hospital mortality among all patients (95% confidence interval, -1.87% to -0.17%; P = .019). Additionally, among patients who were either on Medicaid or were uninsured (ie, the patients most likely to be impacted by Medicaid expansion), a larger 4.17% decrease in in-hospital mortality was observed (95% confidence interval, -6.47% to -1.87%; P < .001). In contrast, no significant difference-in-difference in mortality was observed for privately insured patients. CONCLUSIONS: Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients and particularly among patients who were either on Medicaid or were uninsured. Our results provide support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion.

Conditional Effects of Race on Operative and Nonoperative Outcomes of Emergency General Surgery Conditions.

INTRODUCTION: Many emergency general surgery (EGS) conditions can be managed both operatively or nonoperatively; however, it is unknown whether the decision to operate affects Black and White patients differentially. METHODS: We identified a nationwide cohort of Black and White Medicare beneficiaries, hospitalized for common EGS conditions from July 2015 to June 2018. Using near-far matching to adjust for measurable confounding and an instrumental variable analysis to control for selection bias associated with treatment assignment, we compare outcomes of operative and nonoperative management in a stratified population of Black and White patients. Outcomes included in-hospital mortality, 30-day mortality, nonroutine discharge, and 30-day readmissions. An interaction test based on a t test was used to determine the conditional effects of operative versus nonoperative management between Black and White patients. RESULTS: A total of 556,087 patients met inclusion criteria, of which 59,519 (10.7%) were Black and 496,568 (89.3%) were White. Overall, 165,932 (29.8%) patients had an operation and 390,155 (70.2%) were managed nonoperatively. Significant outcome differences were seen between operative and nonoperative management for some conditions; however, no significant differences were seen for the conditional effect of race on outcomes. CONCLUSIONS: The decision to manage an EGS patient operatively versus nonoperatively has varying effects on surgical outcomes. These effects vary by EGS condition. There were no significant conditional effects of race on the outcomes of operative versus nonoperative management among universally insured older adults hospitalized with EGS conditions.

National Cohort Study of Resource Utilization in Older Adults With Emergency General Surgery Conditions.

INTRODUCTION: Prior studies have sought to describe Emergency General Surgery (EGS) burden, but a detailed description of resource utilization for both operative and nonoperative management of EGS conditions has not been undertaken. METHODS: Patient and hospital characteristics were extracted from Medicare data, 2015-2018. Operations, nonsurgical procedures, and other resources (i.e., radiology) were defined using Current Procedural Terminology codes. RESULTS: One million eight hundred two thousand five hundred forty-five patients were included in the cohort. The mean age was 74.7 y and the most common diagnoses were upper gastrointestinal. The majority of hospitals were metropolitan (75.1%). Therapeutic radiology services were available in 78.4% of hospitals and operating rooms or endoscopy suites were available in 92.5% of hospitals. There was variability in resource utilization across EGS subconditions, with hepatobiliary (26.4%) and obstruction (23.9%) patients most frequently undergoing operation. CONCLUSIONS: Treatment of EGS diseases in older adults involves several interventional resources. Changes in EGS models, acute care surgery training, and interhospital care coordination may be beneficial to the treatment of EGS patients.

Exploring ethnic differences in post-discharge patterns of surgical care for older adults admitted with diverticulitis.

AIM: We aimed to evaluate ethnic differences in patterns of care following an index nonoperative admission for acute diverticulitis amongst a universally insured patient cohort. METHODS: We identified nationwide Medicare beneficiaries aged 65.5 years or older hospitalized between 1 July 2015 and 1 November 2017 for nonoperative management of an index admission for diverticulitis. Patients were followed for 1 year to examine patterns of care. Primary categorical outcomes included receipt of an elective operation, emergency operation, nonoperative readmission or no further hospitalizations for diverticulitis. Multinomial regression was performed to determine the association between ethnicity and receipt of each primary outcome category whilst adjusting for potential confounders. We examined the use of percutaneous drainage during the index admission to better understand its association with subsequent care patterns. RESULTS: Amongst 22 630 study patients, subsequent operative treatment was less common for Black, Hispanic, Asian and American Indian patients relative to White patients. Multinomial logistic regression noted that Black (relative risk 0.40; 95% CI 0.32-0.50) and Asian (relative risk 0.37; 95% CI 0.15-0.91) patients were associated with the lowest relative risk of undergoing an elective interval operation compared to White patients. Black patients were also associated with a 1.43 (95% CI 1.19-1.73) increased risk of requiring subsequent nonoperative readmissions for disease recurrence compared to White patients. The use of percutaneous drainage was higher amongst White patients relative to Black patients (6.9% vs. 4.0%, P value < 0.001). CONCLUSION: We have identified ongoing inequities in the consumption of medical resources, with White patients being more likely to undergo elective colectomy and percutaneous drainage. Differences in care are not fully alleviated by equal access to insurance.

Exploring the Experience of the Surgical Workforce During the Covid-19 Pandemic.

OBJECTIVE: To explore the impact of the Covid-19 pandemic on the stress levels and experience of academic surgeons by training status (eg, housestaff or faculty). BACKGROUND: Covid-19 has uniquely challenged and changed the United States healthcare system. A better understanding of the surgeon experience is necessary to inform proactive workforce management and support. METHODS: A multi-institutional, cross-sectional telephone survey of surgeons was conducted across 5 academic medical centers from May 15 to June 5, 2020. The exposure of interest was training status. The primary outcome was maximum stress level, measured using the validated Stress Numerical Rating Scale-11 (range 0-10). RESULTS: A total of 335 surveys were completed (49.3% housestaff, 50.7% faculty; response rate 63.7%). The mean maximum stress level of faculty was 7.21 (SD 1.81) and of housestaff was 6.86 (SD 2.06) (P = 0.102). Mean stress levels at the time of the survey trended lower amongst housestaff (4.17, SD 1.89) than faculty (4.56, SD 2.15) (P = 0.076). More housestaff (63.6%) than faculty (40.0%) reported exposure to individuals with Covid-19 (P < 0.001). Subjects reported inadequate personal protective equipment in approximately a third of professional exposures, with no difference by training status (P = 0.557). CONCLUSIONS: During the early months of the Covid-19 pandemic, the personal and professional experiences of housestaff and faculty differed, in part due to a difference in exposure as well as non-work-related stressors. Workforce safety, including adequate personal protective equipment, expanded benefits (eg, emergency childcare), and deliberate staffing models may help to alleviate the stress associated with disease resurgence or future disasters.

The Relationship Between Surgeon Gender and Stress During the Covid-19 Pandemic.

OBJECTIVE: To investigate the relationship between surgeon gender and stress during the Covid-19 pandemic. BACKGROUND: Although female surgeons face difficulties integrating work and home in the best of times, the Covid-19 pandemic has presented new challenges. The implications for the female surgical workforce are unknown. METHODS: This cross-sectional, multi-center telephone survey study of surgeons was conducted across 5 academic institutions (May 15-June 5, 2020). The primary outcome was maximum stress level, measured using the validated Stress Numerical Rating Scale-11. Mixed-effects generalized linear models were used to estimate the relationship between surgeon stress level and gender. RESULTS: Of 529 surgeons contacted, 337 surgeons responded and 335 surveys were complete (response rate 63.7%). The majority of female respondents were housestaff (58.1%), and the majority of male respondents were faculty (56.8%) (P = 0.008). A greater proportion of male surgeons (50.3%) than female surgeons (36.8%) had children ≤18 years (P = 0.015). The mean maximum stress level for female surgeons was 7.51 (SD 1.49) and for male surgeons was 6.71 (SD 2.15) (P < 0.001). After adjusting for the presence of children and training status, female gender was associated with a significantly higher maximum stress level (P < 0.001). CONCLUSIONS: Our findings that women experienced more stress than men during the Covid-19 pandemic, regardless of parental status, suggest that there is more to the gendered differences in the stress experience of the pandemic than the added demands of childcare. Deliberate interventions are needed to promote and support the female surgical workforce during the pandemic.

National Variation in Opioid Prescription Fills and Long-Term Use in Opioid Naïve Patients after Urological Surgery.

PURPOSE: Prescription opioid use is increasing, leading to increased addiction and mortality. Postoperative care is often the first exposure to opioids of a patient but little data exist on national prescription patterns in urology. We examined post-discharge opioid fills after urological procedures and the association with long-term use. MATERIALS AND METHODS: We identified patients in a private national insurance database who underwent 1 of 15 urological procedures between October 1, 2010 and September 30, 2014. Patients with an opioid fill in the preceding 6 months were excluded from study. Claims for opioids from 30 days before the operation until 7 days after discharge characterized an initial prescription. Factors associated with persistent opioid use (an opioid claim 91 to 180 days after the operation) and chronic opioid use (10 or more refills of a 120-day or greater supply in the year after the operation) were analyzed using multivariable logistic regression. RESULTS: Overall 96,580 patients were included in study, of whom 49,391 (51%) filled an initial opioid prescription. Variation in the initial prescribed amount existed within procedures. Persistent use occurred in 6.2% of patients while chronic use occurred in 0.8%. Increased prescription in patients treated with transurethral prostate resection, vasectomy, female sling surgery, cystoscopy and stent insertion were associated with an increased risk of persistent as well as chronic use. CONCLUSIONS: National variation in opioid prescribing practice exists after urological operations. Patients who fill larger amounts of opioids after certain major and minor urological procedures are at increased risk for long-term opioid use. This provides evidence for procedure specific prescribing guidelines to minimize risk and promote standardization.

Does Surgeon Sex Matter?: Practice Patterns and Outcomes of Female and Male Surgeons.

OBJECTIVE: We sought to compare postoperative outcomes of female surgeons (FS) and male surgeons (MS) within general surgery. SUMMARY OF BACKGROUND DATA: FS in the workforce are increasing in number. Female physicians provide exceptional care in other specialties. Differences in surgical outcomes of FS and MS have not been examined. METHODS: We linked the AMA Physician Masterfile to discharge claims from New York, Florida, and Pennsylvania (2012 to 2013) to examine practice patterns and to compare surgical outcomes of FS and MS. We paired FS and MS operating at the same hospital using cardinality matching with refined balance and compared inpatient mortality, any postoperative complication, and prolonged length of stay (pLOS) in FS and MS. RESULTS: Overall practice patterns differed between the 663 FS and 3219 MS. We identified 2462 surgeons (19% FS, 81% MS) at 429 hospitals who met inclusion criteria for outcomes analysis. FS were younger (mean age ±â€ŠSD FS: 48.5 ±â€Š8.4 years, MS: 54.3 ±â€Š9.4y; P < 0.001) with less clinical experience (mean years ±â€ŠSD FS: 11.6 ±â€Š8.3 y, MS: 17.6 ±â€Š10.0 years; P < 0.001) than MS before matching. FS had lower rates of inpatient mortality (FS: 1.51%, MS: 2.30%; P < 0.001), any postoperative complication (FS: 12.6%, MS: 16.1%; P < 0.001), and pLOS (FS: 18.4%, MS: 20.7%; P < 0.001) before matching. After matching, FS and MS outcomes were equivalent. CONCLUSION: Surgeon practice patterns vary by sex and experience. FS and MS with similar characteristics who treat similar patients at the same hospital have equivalent rates of inpatient morality, postoperative complications, and prolonged length of hospital stay. Patients should select the surgeon who is the best fit for them regardless of sex.

National trends in admissions, repair, and mortality for thoracic aortic aneurysm and type B dissection in the National Inpatient Sample.

OBJECTIVE: The advent of endovascular repair for both thoracic aortic aneurysm and type B dissection has transformed the management of these disease processes. This study was undertaken to better define, compare, and contrast the national trends in hospital admissions, invasive treatments, and inpatient mortality of patients with thoracic aortic aneurysm and type B dissection in the National Inpatient Sample. METHODS: The cohort was derived from International Classification of Diseases, Ninth Revision diagnosis codes for thoracic aortic dissection and thoracic aortic or thoracoabdominal aortic aneurysm. Patients receiving type A dissection or ascending aortic repair during their index admission were excluded using International Classification of Diseases, Ninth Revision procedure codes. A total of 155,187 patients were available for analysis from 2000 to 2012. RESULTS: Admissions for thoracic aortic aneurysm outnumbered the admissions for type B dissection (69.8% vs 30.2%; P < .001), and the number of admissions for aneurysm grew more rapidly during this time (132% vs 63%; P < .001). Thoracic endovascular aortic repair (TEVAR) for aneurysm experienced an increase in 2005, concordant with Food and Drug Administration approval of TEVAR for thoracic aortic aneurysm indication, then superseded open repair for thoracic aortic aneurysm from 2006 onward. Despite this, the rate of thoracic aortic aneurysm repair has remained relatively stable over time. TEVAR for dissection increased in 2006, superseded open repair in 2010, and continues to account for 50.5% of all dissection repairs. Overall, the number of type B dissection repairs has increased (P < .001), over and above the increase in number of admissions for type B dissection. Despite the increased trends of utilization of TEVAR for both aneurysm and type B dissection, the overall in-hospital mortality rate among patients admitted for either disease state has decreased steadily over time (P < .001). CONCLUSIONS: Whereas admissions for thoracic aortic aneurysm disease have increased over time, the rate of aneurysm repair has been stable, although TEVAR has supplanted a proportion of open repairs. In contrast, whereas admissions for type B dissection have experienced a more modest increase, there has been a disproportionate increase in type B dissection repair, largely due to increased use of TEVAR. These results show embracing of endovascular technology for dissection through expansion of indication. Despite the increase in rate of repair for type B dissection, inpatient mortality rate was reduced in both aneurysm and dissection patients, influenced by appropriate selection of patients for intervention.

Hospitalization in the Year Preceding Major Oncologic Surgery Increases Risk for Adverse Postoperative Events.

BACKGROUND: Hospitalization is associated with negative clinical effects that last beyond discharge. This study aimed to determine whether hospitalization in the year before major oncologic surgery is associated with adverse outcomes. METHODS: Patients 18 years of age or older with stomach, pancreas, colon, or rectal cancer who underwent resection in California and New York (2008-2010) were included in the study. Patients with hospitalization in the year prior to oncologic resection (HYPOR) were identified. Multivariable logistic regression was used to examine the association of prior hospitalization with the following adverse outcomes: inpatient mortality, complications, complex discharge needs, and 90-day readmission. Subset analysis by cancer type was performed. Outcomes based on temporal proximity of hospitalization to month of surgical admission were evaluated. RESULTS: Of 32,292 patients, 16.3% (n = 5276) were HYPOR. Patients with prior hospitalization were older (median age, 72 vs 67 years; p < 0.001) and had more comorbidities (Elixhauser Index ≥3, 86.5 vs 75.3%; p < 0.001). In the multivariable analysis, HYPOR was associated with complications (odds ratio [OR], 1.28; 95% confidence interval [CI] 1.18-1.40), complex discharge (OR, 1.44; 95% CI 1.34-1.55), and 90-day readmission (OR, 1.45; 95% CI 1.35-1.56). The interval from HYPOR to resection was not associated with adverse outcomes. CONCLUSIONS: Patients hospitalized in the year before oncologic resection are at increased risk for postoperative adverse events. Recent hospitalization is a risk factor that is easily ascertainable and should be used by clinicians to identify patients who may need additional support around the time of oncologic resection.

Factors Associated With Discontinuation of Home Hemodialysis.

BACKGROUND: Home hemodialysis (HHD) is associated with improved clinical and quality-of-life outcomes compared to in-center hemodialysis, but remains an underused modality in the United States. Discontinuation from HHD therapy may be an important contributor to the low use of this modality. This study aimed to describe the rate and timing of HHD therapy discontinuation, or technique failure, and identify contributing factors. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Using data from a large dialysis provider, we identified a nationally representative cohort of patients who initiated HHD therapy from 2007 to 2009 (N=2,840). FACTORS: Demographics, end-stage renal disease duration, kidney transplant listing status, comorbid conditions, level of urbanization or rurality based on residence zip code, socioeconomic status based on residence zip code, and dialysis facility factors. OUTCOMES: Discontinuation from HHD therapy, defined as 60 or more days with no HHD treatments. MEASUREMENTS: Competing-risk models were used to produce cumulative incidence plots and identify sociodemographic and clinical variables associated with HHD therapy discontinuation. Transplantation and death were treated as competing risks for HHD therapy discontinuation. RESULTS: The 1-year incidence of discontinuation was 24.9%, and the 1-year mortality estimate was 7.6%. Median end-stage renal disease duration prior to initiating HHD therapy was 2.1 years. Diabetes and smoking/alcohol/drug use were associated with increased risk for HHD discontinuation (HRs of 1.34 [95% CI, 1.07-1.68] and 1.34 [95% CI, 1.01-1.78], respectively). Listing for kidney transplantation and rural residence (rural-urban commuting area ≥ 7) were associated with decreased risk for HHD therapy discontinuation (HRs of 0.73 [95% CI, 0.61-0.87] and 0.78 [95% CI, 0.59-1.02], respectively). LIMITATIONS: Limited to variables available within the DaVita dialysis and US Renal Data System data sets. CONCLUSIONS: A substantial proportion of patients discontinue HHD therapy within the first 12 months of use of the modality. Patients with diabetes, substance use, nonlisting for kidney transplantation, and urban residence are at greater risk for discontinuation. Targeting high-risk patients for increased support from clinical teams is a potential strategy for reducing HHD therapy discontinuation and increasing technique survival.

Association between skilled nursing facility quality indicators and hospital readmissions.

IMPORTANCE: Hospital readmissions are common, costly, and potentially preventable. Little is known about the association between available skilled nursing facility (SNF) performance measures and the risk of hospital readmission. OBJECTIVE: To measure the association between SNF performance measures and hospital readmissions among Medicare beneficiaries receiving postacute care at SNFs in the United States. DESIGN AND PARTICIPANTS: Using national Medicare data on fee-for-service Medicare beneficiaries discharged to a SNF after an acute care hospitalization between September 1, 2009, and August 31, 2010, we examined the association between SNF performance on publicly available metrics (SNF staffing intensity, health deficiencies identified through site inspections, and the percentages of SNF patients with delirium, moderate to severe pain, and new or worsening pressure ulcers) and the risk of readmission or death 30 days after discharge to a SNF. Adjusted analyses controlled for patient case mix, SNF facility factors, and the discharging hospital. MAIN OUTCOMES AND MEASURES: Readmission to an acute care hospital or death within 30 days of the index hospital discharge. RESULTS: Of 1,530,824 patients discharged, 357,752 (23.3%; 99% CI, 23.3%-23.5%) were readmitted or died within 30 days; 72,472 died within 30 days (4.7%; 99% CI, 4.7%-4.8%), and 321,709 were readmitted (21.0%; 99% CI, 20.9%-21.1%). The unadjusted risk of readmission or death was lower at SNFs with better staffing ratings. SNFs ranked lowest (19.2% of all SNFs) had a 30-day risk of readmission or death of 25.5% (99% CI, 25.3%-25.8%) vs 19.8% (99% CI, 19.5%-20.1%) among those ranked highest. SNFs with better facility inspection ratings also had a lower risk of readmission or death. SNFs ranked lowest (20.1% of all SNFs) had a risk of 24.9% (99% CI, 24.7%-25.1%) vs 21.5% (99% CI, 21.2%-21.7%) among those ranked highest . Adjustment for patient factors, SNF facility factors, and the discharging hospital attenuated these associations; we observed small differences in the adjusted risk of readmission or death according to SNF facility inspection ratings (lowest vs highest rating: 23.7%; 99% CI: 23.7%, 23.7%; vs 23.0%; 99% CI: 23.0%, 23.1%). Other measures did not predict clinically meaningful differences in the adjusted risk of readmission or death. CONCLUSIONS AND RELEVANCE: Among fee-for-service Medicare beneficiaries discharged to a SNF after an acute care hospitalization, available performance measures were not consistently associated with differences in the adjusted risk of readmission or death.
