Project description:Importance:Emergency department (ED) visits are common and increasing. Whether outcomes associated with care in the ED are improving over time is largely unknown to date. Objective:To examine trends in 30-day mortality rates associated with ED care among Medicare beneficiaries aged 65 years or older. Design, Setting, and Participants:This cross-sectional study used a random 5% sample in 2009 and 2010 and a 20% sample from 2011 to 2016, for a total of 15?416?385 ED visits from 2009 to 2016 among Medicare beneficiaries aged 65 years or older. Exposures:Time (year) as a continuous variable. Main Outcomes and Measures:The primary outcome was 30-day mortality, overall and stratified by illness severity and hospital characteristics. Secondary outcomes included mortality rates on the day of the ED visit (day 0) as well as at 7 and 14 days. Changes in disposition from the ED (admission, observation, transfer, died in the ED, and discharged) over time were also examined. Results:The sample included 15?416?385 ED visits (60.8% women and 39.2% men; mean [SD] age, 78.6 [8.5] years) at 4828 acute care hospitals. The percentage of patients discharged from the ED increased from 53.6% in 2009 to 56.7% in 2016. Unadjusted 30-day mortality declined from 5.1% in 2009 to 4.6% in 2016 (-0.068% per year; 95% CI, -0.074% to -0.063% per year; P?<?.001). After adjusting for hospital random effects, patient demographics, and chronic conditions, the adjusted 30-day mortality trend was -0.198% per year (95% CI, -0.204% to -0.193% per year; P?<?.001). The magnitude of this trend was greatest for patients with a high severity of illness (-0.662%; 95% CI, -0.681% to -0.644%; P?<?.001), followed by those with a medium severity of illness (-0.103% per year; 95% CI, -0.108% to -0.097% per year; P?<?.001) and those with a low severity of illness (-0.009% per year; 95% CI, -0.006% to -0.011% per year; P?<?.001). Declines in mortality were seen in each category of ED disposition, including visits resulting in admission (-0.356% per year; 95% CI, -0.368% to -0.343% per year; P?<?.001) as well as those resulting in discharge (-0.059% per year; 95% CI, -0.064% to -0.055% per year; P?<?.001). The decline was greater for major teaching hospitals (compared with nonteaching hospitals), nonprofit hospitals (compared with for-profit hospitals), and urban hospitals (compared with rural hospitals). Conclusions and Relevance:Among Medicare beneficiaries receiving ED care in the United States, mortality within 30 days of an ED visit appears to have declined in recent years, particularly for patients with the highest severity of illness, even as fewer patients are being admitted from an ED visit. This study's findings suggest that further study is needed to understand the reasons for this decline and why certain types of hospitals are seeing greater improvements in outcomes.

Project description:ImportanceThere has been a significant increase in the implementation and dissemination of geriatric emergency department (GED) programs. Understanding the costs associated with patient care would yield insight into the direct financial value for patients, hospitals, health systems, and payers.ObjectiveTo evaluate the association of GED programs with Medicare costs per beneficiary.Design, setting, and participantsThis cross-sectional study included data on Medicare fee-for-service beneficiaries at 2 hospitals implementing Geriatric Emergency Department Innovations in Care Through Workforce, Informatics, and Structural Enhancement (GEDI WISE) (Mount Sinai Medical Center [MSMC] and Northwestern Memorial Hospital [NMH]) from January 1, 2013, to November 30, 2016. Analyses were conducted and refined from August 28, 2018, to November 20, 2020, using entropy balance to account for observed differences between the treatment and comparison groups.InterventionsTreatment included consultation with a transitional care nurse (TCN) or a social worker (SW) trained for the GEDI WISE program at a beneficiary's first ED visit (index ED visit). The comparison group included beneficiaries who were never seen by either a TCN or an SW during the study period.Main outcomes and measuresThe main outcome evaluated was prorated total Medicare payer expenditures per beneficiary over 30 and 60 days after the index ED visit encounter.ResultsOf the total 24 839 unique Medicare beneficiaries, 4041 were seen across the 2 EDs; 1947 (17.4%) at MSMC and 2094 (15.4%) at the NMH received treatment from either a GED TCN and/or a GED SW. The mean (SD) age of beneficiaries at MSMC was 78.8 (8.5) years and at NMH was 76.4 (7.7) years. Most patients at both hospitals were female (6821 [60.8%] at MSMC and 8023 [58.9%] at NMH) and White (7729 [68.9%] at MSMC and 9984 [73.3%] at NMH). Treatment was associated with statistically significant mean savings per beneficiary of $2436 (95% CI, $1760-$3111; P < .001) at one ED and $2905 (95% CI, $2378-$3431; P < .001) at the other ED in the 30 days after the index ED visit. The association between treatment and mean cumulative savings at 60 days after the index ED visit per beneficiary was also significant: $1200 (95% CI, $231-$2169; P = .02) at one ED and $3202 (95% CI, $2452-$3951; P < .001) at the other ED.Conclusions and relevanceAmong Medicare fee-for-service beneficiaries, receipt of ED-based geriatric treatment by a TCN and/or an SW was associated with lower Medicare expenditures. These estimated cost savings may be used when calculating or considering the bundled value and potential reimbursement per patient for GED care programs.

Project description:ImportanceAmbulatory follow-up care is frequently recommended after an emergency department (ED) visit. However, the frequency with which follow-up actually occurs and the degree to which follow-up is associated with postdischarge outcomes is unknown.ObjectivesTo examine the frequency and variation in ambulatory follow-up among Medicare beneficiaries discharged from US EDs and the association between ambulatory follow-up and postdischarge outcomes.Design, setting, and participantsThis cohort study of 9 470 626 ED visits to 4728 US EDs among Medicare beneficiaries aged 65 and older from 2011 to 2016 who survived the ED visit and were discharged to home used Kaplan-Meier curves and proportional hazards regression. Data analysis was conducted from December 2019 to July 2020.ExposuresAmbulatory follow-up after discharge from the ED.Main outcomes and measuresPostdischarge mortality, subsequent ED visit, or inpatient hospitalization within 30 days of an index ED visit.ResultsThe study sample consisted of 9 470 626 index outpatient ED visits to 4684 EDs; most visits (5 776 501 [61.0%]) were among women, and the mean (SD) age of patients was 77.3 (8.4) years. In this sample, the cumulative incidence of ambulatory follow-up was 40.5% (3 822 133 patients) at 7 days and 70.8% (6 662 525 patients) at 30 days, after accounting for censoring and for mortality as a competing risk. Characteristics associated with lower rates of ambulatory follow-up included beneficiary Medicaid eligibility (hazard ratio [HR], 0.77; 95% CI, 0.77-0.78; P < .001), Black race (HR, 0.82; 95% CI, 0.81-0.83; P < .001), and treatment at a rural ED (HR, 0.75; 95% CI, 0.73-0.77; P < .001) in the multivariable regression model. Ambulatory follow-up was associated with lower risk of postdischarge mortality (HR, 0.49; 95% CI, 0.49-0.50; P < .001) but higher risk of subsequent inpatient hospitalization (HR, 1.22; 95% CI, 1.21-1.23; P < .001) and ED visits (HR, 1.01; 95% CI, 1.00-1.01; P < .001), adjusting for visit diagnosis, patient demographic characteristics, and chronic conditions.Conclusions and relevanceIn this cohort study of Medicare beneficiaries discharged from the ED, nearly 30% lacked ambulatory follow-up at 30 days, with variation in follow-up rates by patient and hospital characteristics. Having an ambulatory follow-up visit was associated with higher risk of subsequent hospitalization but lower risk of mortality. Ambulatory care access may be an important driver of clinical outcomes after an ED visit.

Project description:ImportanceRural US residents disproportionately rely on emergency departments (ED), yet little is known about patient outcomes after ED visits to rural hospitals or critical access hospitals (CAHs).ObjectiveTo compare 30-day outcomes after rural vs urban ED visits and in CAHs, a subset of rural hospitals.Design, setting, and participantsThis propensity-matched, retrospective cohort study used a 20% sample of national Medicare fee-for-service beneficiaries from January 1, 2011, to October 31, 2015. Rural and urban ED visits were matched on demographics, patient prior use of EDs, comorbidities, and diagnoses. Thirty-day outcomes overall and stratified by 25 common ED diagnoses were evaluated, with similar analysis of CAHs vs non-CAHs. Data were analyzed from February 15, 2020, to May 17, 2021.Main outcomes and measuresThe primary outcome was 30-day all-cause mortality. Secondary outcomes were ED revisits with and without hospitalization.ResultsThe matched cohort included 473 152 rural and urban Medicare beneficiaries with a mean (SD) age of 75.1 (7.9) years (59.1% and 59.3% women, respectively; 86.9% and 87.1% White, respectively). Medicare beneficiaries at rural vs urban EDs experienced similar all-cause 30-day mortality (3.9% vs 4.1%; effect size, 0.01), ED revisits (18.1% vs 17.8%; effect size, 0.00), and ED revisits with hospitalization (6.0% vs 8.1%; effect size, 0.00). Rural ED visits were associated with more transfer (6.2% vs 2.0%; effect size, 0.22) and fewer hospitalizations (24.7% vs 39.2; effect size, 0.31). Stratified by diagnosis, patients in rural EDs with life-threatening illnesses experienced more transfer with 30-day mortality similar to that of patients in urban EDs. In contrast, mortality differed for patients in rural EDs with symptom-based diagnoses, including chest pain (odds ratio [OR], 1.54 [95% CI, 1.25-1.89]), nausea and vomiting (OR, 1.68 [95% CI, 1.26-2.24), and abdominal pain (OR, 1.73 [95% CI, 1.42-2.10]). All findings were similar for CAHs.Conclusions and relevanceThe findings of this cohort study of rural ED care suggest that patient mortality for potentially life-threatening conditions is comparable to that in urban settings. Further research is needed to understand the sources of greater rural ED mortality for symptom-based conditions. These findings underscore the importance of ensuring access to treatment of life-threatening conditions at local EDs in rural communities, which are increasingly endangered by hospital closures.

Project description:ImportancePrior authorization requirements may be a barrier to accessing medications for opioid use disorder treatment and may, therefore, be associated with poor health care outcomes.ObjectiveTo determine the association of prior authorization with use of buprenorphine-naloxone and health care outcomes.Design, setting, and participantsThis comparative interrupted time series analysis examined enrollment and insurance claims data from Medicare beneficiaries with an opioid use disorder diagnosis or who filled a prescription for an opioid use disorder medication between 2012 and 2017. Over this period, 775?874 members were in 1479 Part D plans that always required prior authorization, 113?286 members were in 206 plans that removed prior authorization, 189?461 members were in 489 plans that never required prior authorization, and 619?919 members were in 485 plans that added prior authorization. Data analysis was performed from April 2019 to February 2020.ExposuresRemoval or addition of prior authorization and new prescriptions filled for buprenorphine-naloxone.Main outcomes and measuresBuprenorphine-naloxone use, inpatient admissions, emergency department visits, and prescription drug and medical expenditures.ResultsThe study population in 2012 included 949?206 Medicare beneficiaries (mean [SD] age, 57 [15] years; 550?445 women [58%]). Removal of prior authorization was associated with an increase of 17.9 prescriptions (95% CI, 1.1 to 34.7 prescriptions) filled for buprenorphine-naloxone per plan per year, which is a doubling of the number of prescriptions, on average. Each prescription filled was associated with statistically significant decreases in adverse health care outcomes: substance use disorder-related inpatient admissions decreased by 0.1 admission per plan per year (95% CI, -0.2 to -0.1 admission per plan per year), and substance use disorder-related emergency department visits decreased by 0.1 visit per plan per year (95% CI, -0.13 to -0.03 visit per plan per year) (all P?<?.001). Combining these results, removal of prior authorization was associated with a reduction in substance use disorder-related inpatient admissions by 2.0 admissions per plan per year (95% CI, -4.3 to -0.1 admissions per plan per year) and substance use disorder-related emergency department visits by 1.4 visits per plan per year (95% CI, -3.2 to -0.1 visits per plan per year).Conclusions and relevanceRemoving prior authorization for buprenorphine-naloxone was associated with an increase in the medication use and decreases in health care utilization and expenditures.

Project description:The objective of this study was to examine the longitudinal patterns of emergency department (ED) visits among adult fee-for-service Medicaid.Data were obtained from the Medicaid analytic eXtract files, Area Health Resource File, and County Health Rankings.A retrospective longitudinal study design, with four observations for each individual was used. The study population consisted of 33,393 Medicaid beneficiaries who met inclusion criteria. ED visits were time-lagged and time-varying patient-level factors were measured for each year. Time-invariant characteristics (gender and race/ethnicity) were measured in 2006. Multivariable hurdle models with logistic (ED use versus no ED use) and negative binomial regressions (ED visits among ED users) were used to analyze the ED visits over time. To account for correlation due to repeated observations, mixed effect models with robust standard errors were performed.In both unadjusted and adjusted analysis, the likelihood of ED use did not change from year to year (AOR = 1.00, 95 percent CI: 0.99, 1.01). Among ED users, the estimated number of ED visits increased over time (IRR = 1.01, 95 percent CI: 1.01, 1.03).Primary care resources should be a major focus to reduce the increased burden on the EDs.

Project description:ObjectiveTo identify patient social risk factors associated with Continuity of Care (COC) index.Data sources/study settingMedicare Current Beneficiary Survey (MCBS), the Dartmouth Institute, and Area Resource File for 2006-2013.Study designWe use regression methods to assess the effect of patient social risk factors on COC after adjusting for medical complexity. In secondary analyses, we assess the effect of social risk factors on annual utilization of physicians and specialists for evaluation and management (E&M).Data collection/extraction methodsWe retrospectively identified 59 499 patient years for Medicare beneficiaries with one year of enrollment and three or more E&M visits.Principal findingsAfter adjustment for medical complexity, individual-level social risk factors such as lack of education, low income, and living alone are all associated with better patient COC (P < .05). Similarly, area-level social risk factors such as living in areas that are nonurban or high poverty, as well as in areas with low specialist or high primary care physician supply, are all associated with better patient COC (P < .05). We found the opposite pattern of associations between these same risk factors and annual patient utilization of physicians and specialists (P < .05).ConclusionsMedicare patients with multiple social risk factors have consistently better COC; these same social risk factors are associated with reduced patient-realized access to specialist physician care.

Project description:It is not known whether recent declines in ischemic heart disease and its risk factors have been accompanied by declines in heart failure (HF) hospitalization and mortality.To examine changes in HF hospitalization rate and 1-year mortality rate in the United States, nationally and by state or territory.From acute care hospitals in the United States and Puerto Rico, 55,097,390 fee-for-service Medicare beneficiaries hospitalized between 1998 and 2008 with a principal discharge diagnosis code for HF.Changes in patient demographics and comorbidities, HF hospitalization rates, and 1-year mortality rates.The HF hospitalization rate adjusted for age, sex, and race declined from 2845 per 100,000 person-years in 1998 to 2007 per 100,000 person-years in 2008 (P < .001), a relative decline of 29.5%. Age-adjusted HF hospitalization rates declined over the study period for all race-sex categories. Black men had the lowest rate of decline (4142 to 3201 per 100,000 person-years) among all race-sex categories, which persisted after adjusting for age (incidence rate ratio, 0.81; 95% CI, 0.79-0.84). Heart failure hospitalization rates declined significantly faster than the national mean in 16 states and significantly slower in 3 states. Risk-adjusted 1-year mortality decreased from 31.7% in 1999 to 29.6% in 2008 (P < .001), a relative decline of 6.6%. One-year mortality rates declined significantly in 4 states but increased in 5 states.The overall HF hospitalization rate declined substantially from 1998 to 2008 but at a lower rate for black men. The overall 1-year mortality rate declined slightly over the past decade but remains high. Changes in HF hospitalization and 1-year mortality rates were uneven across states.

Project description:BACKGROUND:Delirium is common among seniors discharged from the emergency department (ED) and associated with increased risk of mortality. Prior research has addressed mortality associated with seniors discharged from the ED with delirium, however has generally relied on data from one or a small number of institutions and at single time points. OBJECTIVES:Analyse mortality rates among seniors discharged from the ED with delirium up to 12 months at the national level. DESIGN:Retrospective cohort study. SETTING:Analysed data from the Centers for Medicare & Medicaid Services limited data sets for 2012-2013. PARTICIPANTS:Medicare fee-for-service beneficiaries aged 65 years or older discharged from the ED. We focused on new incident cases of delirium, patients with any prior claims for delirium, hospice claims or end-stage renal disease were excluded. Sample size included 26?245 delirium claims, and a randomly selected sample of 262?450 controls. OUTCOME MEASURES:Mortality within 12 months after discharge from the ED, excluding patients transferred or admitted as inpatients. RESULTS:Among all beneficiaries, 46?508 (16.1%) died within 12 months, of which 39?404 (15.0%) were in the non-delirium (ie, control group) and 7104 (27.1%) were in the delirium cohort, respectively. Mortality was strongest at 30 days with an adjusted HR of 4.82 (95% CI 4.60 to 5.04). Over time, delirium was consistently associated with increased mortality risk compared with controls up to 12?months (HR 2.07; 95% CI 2.01 to 2.13). Covariates that affected mortality included older age, comorbidity and presence of dementia. CONCLUSIONS:Our results demonstrate delirium is a significant marker of mortality among seniors in the ED, and mortality risk is most salient in the first 3 months following an ED visit. Given the significant clinical and financial implications, there is a need to increase delirium screening and management within the ED to help identify and treat this potentially fatal condition.

Project description:Importance:Meta-analyses have suggested that initiating pulmonary rehabilitation after an exacerbation of chronic obstructive pulmonary disease (COPD) was associated with improved survival, although the number of patients studied was small and heterogeneity was high. Current guidelines recommend that patients enroll in pulmonary rehabilitation after hospital discharge. Objective:To determine the association between the initiation of pulmonary rehabilitation within 90 days of hospital discharge and 1-year survival. Design, Setting, and Patients:This retrospective, inception cohort study used claims data from fee-for-service Medicare beneficiaries hospitalized for COPD in 2014, at 4446 acute care hospitals in the US. The final date of follow-up was December 31, 2015. Exposures:Initiation of pulmonary rehabilitation within 90 days of hospital discharge. Main Outcomes and Measures:The primary outcome was all-cause mortality at 1 year. Time from discharge to death was modeled using Cox regression with time-varying exposure to pulmonary rehabilitation, adjusting for mortality and for unbalanced characteristics and propensity to initiate pulmonary rehabilitation. Additional analyses evaluated the association between timing of pulmonary rehabilitation and mortality and between number of sessions completed and mortality. Results:Of 197?376 patients (mean age, 76.9 years; 115?690 [58.6%] women), 2721 (1.5%) initiated pulmonary rehabilitation within 90 days of discharge. A total of 38?302 (19.4%) died within 1 year of discharge, including 7.3% of patients who initiated pulmonary rehabilitation within 90 days and 19.6% of patients who initiated pulmonary rehabilitation after 90 days or not at all. Initiation within 90 days was significantly associated with lower risk of death over 1 year (absolute risk difference [ARD], -6.7% [95% CI, -7.9% to -5.6%]; hazard ratio [HR], 0.63 [95% CI, 0.57 to 0.69]; P?<?.001). Initiation of pulmonary rehabilitation was significantly associated with lower mortality across start dates ranging from 30 days or less (ARD, -4.6% [95% CI, -5.9% to -3.2%]; HR, 0.74 [95% CI, 0.67 to 0.82]; P?<?.001) to 61 to 90 days after discharge (ARD, -11.1% [95% CI, -13.2% to -8.4%]; HR, 0.40 [95% CI, 0.30 to 0.54]; P?<?.001). Every 3 additional sessions was significantly associated with lower risk of death (HR, 0.91 [95% CI, 0.85 to 0.98]; P?=?.01). Conclusions and Relevance:Among fee-for-service Medicare beneficiaries hospitalized for COPD, initiation of pulmonary rehabilitation within 3 months of discharge was significantly associated with lower risk of mortality at 1 year. These findings support current guideline recommendations for pulmonary rehabilitation after hospitalization for COPD, although the potential for residual confounding exists and further research is needed.
