RESUMEN
BACKGROUND: In women ≥ 70 years of age with T1N0 hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer, breast surgery type and omission of axillary surgery or radiation therapy (RT) do not impact overall survival. Although frailty and life expectancy ideally factor into therapy decisions, their impact on therapy receipt is unclear. We sought to identify trends in and factors associated with locoregional therapy type by frailty and life expectancy. METHODS: Women ≥ 70 years of age with T1N0 HR+/HER2- breast cancer diagnosed in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database between 2010 and 2015 were stratified by validated claims-based frailty and life expectancy measures. Therapy trends over time by regimen intensity ('high intensity': lumpectomy + axillary surgery + RT, or mastectomy + axillary surgery; 'moderate intensity': lumpectomy + RT, lumpectomy + axillary surgery, or mastectomy only; or 'low intensity': lumpectomy only) were analyzed. Factors associated with therapy type were identified using generalized linear mixed models. RESULTS: Of 16,188 women, 21.8% were frail, 22.2% had a life expectancy < 5 years, and only 12.3% fulfilled both criteria. In frail women with a life expectancy < 5 years, high-intensity regimens decreased significantly (48.8-31.2%; p < 0.001) over the study period, although in 2015, 30% still received a high-intensity regimen. In adjusted analyses, frailty and life expectancy < 5 years were not associated with breast surgery type but were associated with a lower likelihood of axillary surgery (frailty: odds ratio [OR] 0.86, 95% confidence interval [CI] 0.76-0.96; life expectancy < 5 years: OR 0.22, 95% CI 0.20-0.25). Life expectancy < 5 years was also associated with a lower likelihood of RT receipt in breast-conserving surgery patients (OR 0.30, 95% CI 0.27-0.34). CONCLUSIONS: Rates of high-intensity therapy are decreasing but overtreatment persists in this population. Continued efforts aimed at appropriate de-escalation of locoregional therapy are needed.

INTRODUCTION: As the benefits of intensive locoregional therapy for ductal carcinoma in situ (DCIS) are realized over time in older adults, life expectancy may help to guide treatment decisions. We examined whether life expectancy was associated with extent of locoregional therapy in this population. PATIENTS AND METHODS: Women ≥ 70 years old with < 5 cm of DCIS diagnosed 2010-2015 were identified in the Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset and categorized by a life expectancy ≤ 5 or > 5 years, defined by a validated claims-based measure. Differences in locoregional therapy (mastectomy + axillary surgery, mastectomy-only, lumpectomy + radiation therapy (RT) + axillary surgery, lumpectomy + RT, lumpectomy-only, and no treatment) by life expectancy were assessed using Pearson chi-squared tests. Generalized linear mixed models were used to identify factors associated with receipt of lumpectomy-only. RESULTS: Of 5346 women (median age of 75 years, range 70-97 years), 927 (17.3%) had a life expectancy ≤ 5 years. Of the 4041 patients who underwent lumpectomy, 710 (13.3%) underwent axillary surgery. More patients with life expectancy ≤ 5 years underwent lumpectomy-only (39.4% versus 27%), mastectomy-only (8.1% versus 5.3%), or no treatment (5.8% versus 3.2%; p < 0.001). On multivariable analysis, women with life expectancy ≤ 5 years had a significantly greater likelihood of undergoing lumpectomy-only [OR 1.90, 95% CI (1.63-2.22)]. CONCLUSIONS: Life expectancy is associated with lower-intensity locoregional therapy for older women with DCIS, yet a large proportion of patients with a life expectancy ≤ 5 years received RT and axillary surgery, highlighting potential overtreatment and opportunities to de-escalate locoregional therapy in older adults.
RESUMEN
BACKGROUND: Randomized controlled trials show that certain axillary surgical practices can be safely deescalated in older adults with early-stage breast cancer. Hospital volume is often equated with surgical quality, but it is unclear whether this includes performance of low-value surgeries. We sought to describe how utilization of two low-value axillary surgeries has varied by time and hospital volume. METHODS: Women aged ≥ 70 years diagnosed with breast cancer from 2013 to 2016 were identified in the National Cancer Database. The outcomes of interest were sentinel lymph node biopsy (SLNB) in cT1N0 hormone receptor-positive cancer patients and axillary lymph node dissection (ALND) in cT1-2N0 patients undergoing breast-conserving surgery with ≤ 2 pathologically positive nodes. Time trends in procedure use and multivariable regression with restricted cubic splines were performed, adjusting for patient, disease, and hospital factors. RESULTS: Overall, 83.4% of 44,779 women eligible for omission of SLNB underwent SLNB and 20.0% of 7216 patients eligible for omission of ALND underwent ALND. SLNB rates did not change significantly over time and remained significantly different by age group (70-74 years: 93.5%; 75-79 years: 89.7%, 80-84 years: 76.7%, ≥ 85 years: 48.9%; p < 0.05). ALND rates decreased over the study period across all age groups included (22.5 to 16.9%, p < 0.001). In restricted cubic splines models, lower hospital volume was associated with higher likelihood of undergoing SLNB and ALND. CONCLUSIONS: ALND omission has been more widely adopted than SLNB omission in older adults, but lower hospital volume is associated with higher likelihood of both procedures. Practice-specific deimplementation strategies are needed, especially for lower-volume hospitals.
RESUMEN
OBJECTIVE: In a recent analysis, we discovered lower mortality after open abdominal aortic aneurysm repair (OAAA) in the Society for Vascular Surgery Vascular Quality Initiative (VQI) database when compared with previously published reports of other national registries. Understanding differentials in these registries is essential for their utility because such datasets increasingly inform clinical guidelines and health policy. METHODS: The VQI, American College of Surgeons National Surgical Quality Improvement Program (NSQIP), and National Inpatient Sample (NIS) databases were queried to identify patients who had undergone elective OAAA between 2013 and 2016. χ2 tests were used for frequencies and analysis of variance for continuous variables. RESULTS: In total, data from 8775 patients were analyzed. Significant differences were seen across the baseline characteristics included. Additionally, the availability of patient and procedural data varied across datasets, with VQI including a number of procedure-specific variables and NIS with the most limited clinical data. Length of stay, primary insurer, and discharge destination differed significantly. Unadjusted in-hospital mortality also varied significantly between datasets: NIS, 5.5%; NSQIP, 5.2%; and VQI, 3.3%; P < .001. Similarly, 30-day mortality was found to be 3.5% in VQI and 5.9% in NSQIP (P < .001). CONCLUSIONS: There are fundamental important differences in patient demographic/comorbidity profiles, payer mix, and outcomes after OAAA across widely used national registries. This may represent differences in outcomes between institutions that elect to participate in the VQI and NSQIP compared with patient sampling in the NIS. In addition to avoiding direct comparison of information derived from these databases, it is critical these differences are considered when making policy decisions and guidelines based on these "real-world" data repositories.

OBJECTIVE: This study simulates the regionalization of pancreatectomies to assess its impact on spatial access in terms of patient driving times. BACKGROUND: Although policies to regionalize complex procedures to high-volume centers may improve outcomes, the impact on patient access is unknown. METHODS: Patients who underwent pancreatectomies from 2005 to 2014 were identified from California's statewide database. Round-trip driving times between patients' home ZIP code and hospital addresses were calculated via Google Maps. Regionalization was simulated by eliminating hospitals performing <20 pancreatectomies/yr, and reassigning patients to the next closest hospital that satisfied the volume threshold. Sensitivity analyses were performed for New York and Medicare patients to assess for influence of geography and insurance coverage, respectively. RESULTS: Of 13,317 pancreatectomies, 6335 (47.6%) were performed by hospitals with <20 cases/yr. Patients traveled a median of 49.8 minutes [interquartile range (IQR) 30.8-96.2] per round-trip. A volume-restriction policy would increase median round-trip driving time by 24.1 minutes (IQR 4.5-53.5). Population in-hospital mortality rates were estimated to decrease from 6.7% to 2.8% (P < 0.001). Affected patients were more likely to be racial minorities (44.6% vs 36.5% of unaffected group, P < 0.001) and covered by Medicaid or uninsured (16.3% vs 9.8% of unaffected group, P < 0.001). Sensitivity analyses revealed a 17.8 minutes increment for patients in NY (IQR 0.8-47.4), and 27.0 minutes increment for Medicare patients (IQR 6.2-57.1). CONCLUSIONS: A policy that limits access to low-volume pancreatectomy hospitals will increase round-trip driving time by 24 minutes, but up to 54 minutes for 25% of patients. Population mortality rates may improve by 1.5%.

BACKGROUND: The volume-outcome relationship for organ-specific transplantation is well-described; it is unknown if the relative balance of kidney compared with liver volumes within an institution relates to organ-specific outcomes. We assessed the association between relative balance within a transplant center and outcomes. METHODS: National retrospective analysis of isolated kidney and liver transplants in United States 2005-2014 followed through 2019. Latent class analysis defined transplant center phenotypes. Multivariate Cox models estimated death-censored graft loss and mortality. RESULTS: Latent class analysis identified four phenotypes: kidney only (n = 117), kidney dominant (n = 36), mixed/balanced (n = 90), and liver dominant (n = 13). Compared to mixed centers, the risk of kidney graft loss was higher at kidney-dominant (HR 1.07, p < .001) and liver-dominant (HR 1.10, p < .001) centers, while kidney-only (HR 1.06, p = .01) centers had higher mortality. Liver graft loss was not associated with phenotype, but risk of patient death was lower (HR 0.93, p = .02) at liver dominant and higher (HR 1.06, p = .02) at kidney-dominant centers. CONCLUSIONS: A mixed phenotype was associated with improved kidney transplant outcomes, whereas liver transplant outcomes were best at liver-dominant centers. While these findings need to be verified with center-level resources, optimization of shared resources could improve patient and organ outcomes.

OBJECTIVE: Dementia has been associated with increased complications and mortality in orthopedics and other surgical specialties, but has received limited attention in vascular surgery. Therefore, we evaluated the association of dementia with surgical outcomes for elderly patients with Medicare who underwent a variety of open and percutaneous vascular surgery procedures. METHODS: We reviewed claims data from the Centers for Medicare and Medicaid Services for beneficiaries enrolled in Medicare Part A fee-for-service insurance from January 1, 2011, to December 31, 2011, who underwent inpatient vascular surgery. Only the first surgery during the first admission was considered for analysis. Traditional outcomes (30- and 90-day mortality, intensive care admission, complications, length of stay) and patient-centered outcomes (discharge to home, extended skilled nursing facility [SNF] stay, time at home) were adjusted for patient and procedure characteristics using multilevel linear or logistic regression as appropriate. All analyses were performed using SAS (v9.4, SAS Institute Inc, Cary, NC). RESULTS: Our study included 210,918 patients undergoing vascular surgery, of whom 27,920 carried a diagnosis of dementia. The average age of the entire cohort was 75.74 years, and 55.43% were male. Patients with dementia were older and had higher rates of comorbidities compared with patients without a dementia diagnosis. The three most common defined classes of intervention excluding miscellaneous ones were cerebrovascular, peripheral arterial, and aortic cases, which jointly accounted for 53.15% of cases. Among all cases, 56.62% were open. Emergent/urgent cases were more frequent amongst those with dementia (60.66% vs 37.93%; P < .001). After adjustment, patients with dementia had increased odds of 30-day mortality (odds ratio [OR], 1.21; P < .0001) and 90-day mortality (OR, 1.63; P < .0001), extended SNF stay (OR, 3.47; P < .0001), and longer hospital length of stay (8.29 days vs 5.41 days; P < .001). They were less likely to be discharged home (OR, 0.31; P < .0001) and spent a lower fraction of time at home after discharge (63.29% vs 86.91%; P < .001). Intensive care admission and inpatient complications were similar between the two groups. CONCLUSIONS: Dementia is associated with poor traditional outcomes, including increased 30- and 90-day mortality and longer hospital lengths of stay in this large national patient sample. It is also associated with worse patient-centered outcomes, including substantially lower discharge rates to home, less time spent at home after discharge, and higher rates of extended stay in a SNF. These data should be used to counsel patients facing vascular surgery to provide goal-concordant care, particularly to patients with dementia.

BACKGROUND: Risk prediction accuracy of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Surgical Risk Calculator has been shown to differ between emergency and elective surgery. Benchmarking methods of clinical performance require accurate risk estimation, and current methods rarely account for admission source; therefore, our goal was to assess whether the ACS-NSQIP predicts mortality comparably between transferred and nontransferred emergency general surgery (EGS) cases. MATERIALS AND METHODS: This is a retrospective study using the ACS-NSQIP database from 2005 to 2014including all inpatients who underwent one of seven previously described EGS procedures. The admission source was classified as directly admitted versus transferred from an outside emergency room or an acute care facility. We compared the accuracy of ACS-NSQIP-predicted mortality probabilities using the observed-to-expected (O:E) ratio and Brier score. A subgroup analysis was performed to compare accuracy of high-risk and low-risk procedures. RESULTS: A total of 206,103 EGS admissions were identified, of which 6.97% were transfers. Overall mortality was 3.26% for the entire cohort and 10.24% within the transfer group. The O:E ratios generated by ACS-NSQIP models differed between transferred patients (O:E = 1.0, 95% confidence interval = 0.97-1.02) and nontransferred patients (O:E = 1.12, 95% confidence interval = 1.09-1.14). The Brier score for transferred patients was greater than that for nontransferred patients (0.063 versus 0.018, respectively) showing higher accuracy for nontransferred patients. CONCLUSIONS: The ACS-NSQIP risk estimates used for benchmarking differ between transferred and nontransferred EGS cases. Analyses of the Brier score by the ACS-NSQIP risk calculator demonstrated inferior prediction for transferred patients. This increased burden on accepting institutions will have an impact on quality metrics and should be considered for benchmarking of clinical performance.

OBJECTIVE: To determine travel patterns for patients undergoing gastrectomy for cancer and to identify factors associated with patient decision. BACKGROUND: Support for regionalization of complex surgery grows; however, little is known about the willingness of patients to travel for care. Furthermore, utilization of outcomes data in patients' hospital selection processes is not well understood. METHODS: Analysis of the California Office of Statewide Health Planning and Development database from 1996 to 2009. Outcome measures included total distance traveled and rate of bypassing the nearest gastrectomy-performing hospitals. Multivariate analyses to identify predictors of bypassing local hospitals were performed. RESULTS: Total study population was 10,022. Majority (67.1%) of patients underwent gastrectomy at the nearest providing hospitals. Distance traveled to destination hospitals in California averaged 17.04 miles. Bypassing patients traveled approximately 16 miles beyond the nearest hospitals to receive care, selecting lower volume destination hospitals in 27.9% of cases. Annual gastrectomy volumes for nearest and for destination hospitals averaged 4.4 and 6.8 cases, respectively, and inhospital mortality rates were 5.9% and 4.8%, respectively. A few patients (19.2%) sought care at teaching hospitals. Rural county residence significantly reduced the likelihood of bypass (P < 0.001). High volume (>7 cases) and teaching status of destination hospitals (both P < 0.001) were predictive of hospital bypass, though no significant association between mortality rate and bypass was identified. CONCLUSIONS: The majority of gastric cancer patients underwent gastrectomy at providing hospitals nearest to home, reflecting little regionalization of gastrectomy in California. Patients' hospital selection appears not to be driven by outcomes data.

BACKGROUND: Opioids are recommended for pain management in patients being cared for and transported by emergency medical services, but no specific guidelines exist for older adults with fall-related injury. Prior research suggests prehospital opioid administration can effectively manage pain in older adults, but less is known about safety in this population. We compared short-term safety outcomes, including delirium, disposition, and length of stay, among older adults with fall-related injury according to whether they received prehospital opioid analgesia. METHODS: We linked Medicare claims data with prehospital patient care reports for older adults (≥65) with fall-related injury in Illinois between January 1, 2014 and December 31, 2015. We used weighted regression models (logistic, multinomial logistic, and Poisson) to assess the association between prehospital opioid analgesia and incidence of inpatient delirium, hospital disposition, and length of stay. RESULTS: Of 28,150 included older adults, 3% received prehospital opioids. Patients receiving prehospital opioids (vs. no prehospital opioids) were less likely to be discharged home from the emergency department (adjusted probability = 0.30 [95% CI: 0.25, 0.34] vs. 0.47 [95% CI: 0.46, 0.48]), more likely to be discharged to a non-home setting after an inpatient admission (adjusted probability = 0.43 [95% CI: 0.39, 0.48] vs. 0.30 [95% CI: 0.30, 0.31]), had inpatient length of stay 0.4 days shorter (p < 0.001) and ICU length of stay 0.7 days shorter (p = 0.045). Incidence of delirium did not vary between treatment and control groups. CONCLUSIONS: Few older adults receive opioid analgesia in the prehospital setting. Prehospital opioid analgesia may be associated with hospital disposition and length of stay for older adults with fall-related injury. However, our findings do not provide evidence of an association with inpatient delirium. These findings should be considered when developing guidelines for prehospital pain management specific to the older adult population.

INTRODUCTION: We sought to determine how considerations specific to older adults impact between- and within-surgeon variation in axillary surgery use in women ≥70 years with T1N0 HR+ breast cancer. MATERIALS AND METHODS: Females ≥70 years with T1N0 HR+/HER2-negative breast cancer diagnosed from 2013 to 2015 in SEER-Medicare were identified and linked to the American Medical Association Masterfile. The outcome of interest was axillary surgery. Key patient-level variables included the Charlson Comorbidity Index (CCI) score, frailty (based on a claims-based frailty index score), and age (≥75 vs <75). Multilevel mixed models with surgeon clusters were used to estimate the intracluster correlation coefficient (ICC) (between-surgeon variance), with 1-ICC representing within-surgeon variance. RESULTS: Of the 4410 participants included, 6.1% had a CCI score of ≥3, 20.7% were frail, and 58.3% were ≥ 75 years; 86.1% underwent axillary surgery. No surgeon omitted axillary surgery in all patients, but 42.3% of surgeons performed axillary surgery in all patients. In the null model, 10.5% of the variance in the axillary evaluation was attributable to between-surgeon differences. After adjusting for CCI score, frailty, and age in mixed models, between-surgeon variance increased to 13.0%. DISCUSSION: In this population, axillary surgery varies more within surgeons than between surgeons, suggesting that surgeons are not taking an "all-or-nothing" approach. Comorbidities, frailty, and age accounted for a small proportion of the variation, suggesting nuanced decision-making may include additional, unmeasured factors such as differences in surgeon-patient communication.

OBJECTIVE: The interdependence of hospitals is underappreciated in patient outcomes studies. We used a network science approach to foreground this interdependence. Specifically, within two large state-based interhospital networks, we examined the relationship of a hospital's network position with in-hospital mortality and length of stay. METHODS: We constructed interhospital network graphs using data from the Healthcare Cost and Utilization Project and the American Hospital Association Annual Survey for Florida (2014) and California (2011). The exposure of interest was hospital centrality, defined as weighted degree (sum of all ties to a given hospital from other hospitals). The outcomes were in-hospital mortality and length of stay with sub-analyses for four acute medical conditions: pneumonia, heart failure, ischemic stroke, myocardial infarction. We compared outcomes for each quartile of hospital centrality relative to the most central quartile (Q4), independent of patient- and hospital-level characteristics, in this retrospective cross-sectional study. RESULTS: The inpatient cohorts had 1,246,169 patients in Florida and 1,415,728 in California. Compared to Florida's central hospitals which had an overall mortality 1.60%, peripheral hospitals had higher in-hospital mortality (1.97%, adjusted OR (95%CI): Q1 1.61 (1.37, 1.89), p<0.001). Hospitals in the middle quartiles had lower in-hospital mortality compared to central hospitals (%, adjusted OR (95% CI): Q2 1.39%, 0.79 (0.70, 0.89), p<0.001; Q3 1.33%, 0.78 (0.70, 0.87), p<0.001). Peripheral hospitals had longer lengths of stay (adjusted incidence rate ratio (95% CI): Q1 2.47 (2.44, 2.50), p<0.001). These findings were replicated in California, and in patients with heart failure and pneumonia in Florida. These results show a u-shaped distribution of outcomes based on hospital network centrality quartile. CONCLUSIONS: The position of hospitals within an inter-hospital network is associated with patient outcomes. Specifically, hospitals located in the peripheral or central positions may be most vulnerable to diminished quality outcomes due to the network. Results should be replicated with deeper clinical data.

INTRODUCTION: The first states began implementing the Medicaid expansion provisions of the Patient Protection and Affordable Care Act (ACA) in 2014. Studies have yet to address its impact on burn patients. METHODS: Burn patients in geographic regions that expanded Medicaid coverage were compared to patients in regions that did not expand Medicaid before and after implementation of the ACA using bivariate statistics and a difference-in-differences model. A multivariable logistic regression was used to identify factors associated with having Medicaid insurance. The primary outcome of this study was the rate of Medicaid insurance. RESULTS: Of 25,331 discharges, we found greater increases in Medicaid coverage after the ACA in the Medicaid expander regions (23.4-40.2%) compared to the non-expander regions (18.5-20.1%). The difference-in-differences estimate between the expander and non-expander regions was 0.15 (95% CI: 0.11-0.18, p < 0.001). Patients admitted in expander regions were more likely to be insured by Medicaid (OR 1.57 [95%CI 1.21-2.05]), as were patients of Black race (OR 1.25 [95%CI 1.19-1.32), Hispanic ethnicity (OR 1.29 [95%CI 1.14-1.46]), and female sex (OR 1.59 [95%CI 1.11-2.27]). We also found a significant interaction between time period (pre-ACA/post-ACA) and expander region location (OR 2.10 [95%CI 1.67-2.62]). CONCLUSIONS: The Medicaid expansion provision of the ACA led to increased Medicaid coverage among burn patients which was significantly higher in areas with widespread implementation of the expansion.

Importance: Trauma centers improve outcomes for young patients with serious injuries. However, most injury-related hospital admissions and deaths occur in older adults, and it is not clear whether trauma center care provides the same benefit in this population. Objective: To examine whether 30- and 365-day mortality of injured older adults is associated with the treating hospital's trauma center level. Design, Setting, and Participants: This prospective, population-based cohort study used Medicare claims data from January 1, 2013, to December 31, 2016, for all fee-for-service Medicare beneficiaries 66 years or older with inpatient admission for traumatic injury in 2014 to 2015. Data analysis was performed from January 1 to June 31, 2021. Preinjury health was measured using 2013 claims, and outcomes were measured through 2016. The population was stratified by anatomical injury pattern. Propensity scores for level I trauma center treatment were estimated using the Abbreviated Injury Scale, age, and residential proximity to trauma center and then used to match beneficiaries from each trauma level (I, II, III, and IV/non-trauma centers) by injury type. Exposure: Admitting hospital's trauma center level. Main Outcomes and Measures: Case fatality rates (CFRs) at 30 and 365 days after injury, estimated in the matched sample using multivariable, hierarchical logistic regression models. Results: A total of 433â¯169 Medicare beneficiaries (mean [SD] age, 82.9 [8.3] years; 68.4% female; 91.5% White) were included in the analysis. A total of 206â¯275 (47.6%) were admitted to non-trauma centers and 161â¯492 (37.3%) to level I or II trauma centers. Patients with isolated extremity fracture had the fewest deaths (365-day CFR ranged from 16.1% [95% CI, 11.2%-22.4%] to 17.4% [95% CI, 11.8%-24.6%] by trauma center status). Patients with both hip fracture and traumatic brain injury had the most deaths (365-day CFRs ranged from 33.4% [95% CI, 25.8%-42.1%] to 35.8% [95% CI, 28.9%-43.5%]). Conclusions and Relevance: These findings suggest that older adults do not benefit from existing trauma center care, which is designed with younger patients in mind. There is a critical need to improve trauma care practices to address common injury mechanisms and types of injury in older adults.

During the coronavirus disease 2019 (COVID-19) pandemic, states issued and then rescinded stay-at-home orders that restricted mobility. We develop a model of learning by deregulation, which predicts that lifting stay-at-home orders can signal that going out has become safer. Using restaurant activity data, we find that the implementation of stay-at-home orders initially had a limited impact, but that activity rose quickly after states' reopenings. The results suggest that consumers inferred from reopening that it was safer to eat out. The rational, but mistaken inference that occurs in our model may explain why a sharp rise of COVID-19 cases followed reopening in some states.
RESUMEN
BACKGROUND: Previous studies have found an association between androgen deprivation therapy (ADT) and an increased risk of dementia and depression in elderly men. This association remains controversial, and little is known about the effects of ADT in younger men. OBJECTIVE: To examine the association between the receipt of ADT and these outcomes in young men aged 40-64 yr presenting with nonmetastatic prostate cancer (PCa). DESIGN, SETTING, AND PARTICIPANTS: For this observational study, we identified 9117 men aged 40-64 yr diagnosed with localized PCa between 2007 and 2014, without a pre-existing neurocognitive diagnosis, using the TRICARE military database. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Kaplan-Meier curves were fitted to compare ADT versus no ADT. We also performed a subgroup analysis in patients undergoing ADT for ≥12 mo. The association between ADT and new-onset dementia or depression was evaluated using inverse-probability-of treatment-weight-adjusted Cox proportional hazards regression analysis. RESULTS AND LIMITATIONS: Patients receiving ADT had a significantly higher incidence of depression (30.2 vs 15.8 per 1000 person years) and dementia (17.9 vs 7.5 per 1000 person years). The risk of developing either outcome was higher in the ADT cohort (depression: hazard ratio [HR] 2.07, p < 0.001; dementia: HR 1.70, p = 0.052). Additionally, there was a dose-response relationship between the duration of ADT and either outcome. CONCLUSIONS: In our cohort of young men with PCa, the receipt of ADT was associated with an increased risk of developing dementia and depression. Long-term use of ADT was associated with the highest risk of neurocognitive outcomes. PATIENT SUMMARY: In this study, we looked at the risk of dementia and depression in patients <65 yr of age undergoing androgen deprivation therapy (ADT) for prostate cancer. We found that these patients had a higher risk of dementia and depression than those who did not undergo ADT.

BACKGROUND: Cancer center accreditation is designed to identify centers that provide high-quality cancer care. This also guides patients and referring physicians towards centers of excellence for specialized care. We sought to examine if cancer center accreditation was associated with improved long-term oncologic outcomes in patients with pancreatic adenocarcinoma. METHODS: Using the SEER-Medicare database, we identified patients who underwent pancreatectomy for pancreatic adenocarcinoma from 1996 to 2013. Hospitals were categorized into three groups: National Cancer Institute-designated (NCI-designated) centers, Commission on Cancer (CoC)-accredited centers, and "non-accredited" (NA) centers. Multilevel mixed-effects models were used to calculate adjusted examined lymph nodes, disease-specific survival (DSS), and overall survival (OS). RESULTS: We identified 5,118 patients who underwent pancreatectomy at 632 hospitals (41.0% NA, 49.6% CoC, 9.4% NCI). NCI-designated centers had a greater median number of lymph nodes examined compared with CoC-accredited or NA centers (14 vs. 10 vs. 11.0 nodes, respectively; p < 0.001). Patients treated at NCI centers had a higher 5-year DSS compared to those treated at CoC or NA centers (31.2% vs. 23.6% vs. 23.0%, respectively; p < 0.001). Finally, patients treated at NCI centers had a higher 5-year OS compared to those treated at CoC or NA centers (23.5% vs. 18.9% vs. 17.9%, respectively; p < 0.001). The associations held true when adjusted analyses were performed. CONCLUSION: Patients with resected pancreatic cancer treated at NCI-designated centers were associated with improved long-term oncologic outcomes. There was no difference between CoC-accredited centers compared with NA centers. Meticulous validation of accreditation is warranted globally prior to implementation.

IMPORTANCE: Medicare beneficiaries with high medical needs can benefit from Advance Care Planning (ACP). Medicare reimburses clinical providers for ACP discussions, but it is unknown whether high-need beneficiaries are receiving this service. OBJECTIVE: To compare rates of billed ACP discussions among a cohort of high-need Medicare beneficiaries with the non-high-needs Medicare population. DESIGN: Retrospective analysis of Medicare Fee-for-Service (FFS) claims in 2017 comparing high-need beneficiaries (seriously ill, frail, ESRD, and disabled) with non-high need beneficiaries. SETTING: Nationally representative FFS Medicare 20% sample. PARTICIPANTS: Medicare beneficiaries were assigned to one of the following classifications: seriously ill (65+), frail (65+), seriously ill & frail (65+); non-high need (65+); end stage renal disease (ESRD) or disabled (<65). All participants had data available for years 2016-2017. EXPOSURE: Receipt of a billed ACP discussion, CPT codes 99497 or 99498. MAIN OUTCOME AND MEASURE: Rates of billed ACP visits were compared between high-need patients and non-high-need patients. Rates were adjusted for the 65+ population for sex, age, race/ethnicity, Charlson comorbidity index, Medicare/Medicaid dual eligibility status, and Hospital Referral Region. RESULTS: Among the 65+ groups, those most likely to have a billed ACP discussion included seriously ill & frail (5.2%), seriously ill (4.2%), and frail (3.3%). Rates remained consistent after adjusting (4.5%, 4.0%, 3.1%, respectively). Each subgroup differed significantly (p < .05) from non-high need beneficiaries (2.3%) in both unadjusted and adjusted analyses. Among the <65 high need groups, the rates were 2.7% for ESRD and 1.3% for the disabled (the latter p < .05 compared with non-high needs). CONCLUSIONS AND RELEVANCE: While rates of billed ACP discussions varied among patient groups with high medical needs, overall they were relatively low, even among a cohort of patients for whom ACP may be especially relevant.
