Follow-up Post-discharge and Readmission Disparities Among Medicare Fee-for-Service Beneficiaries, 2018.

ABSTRACT:

Background

Previous studies have identified disparities in readmissions among Medicare beneficiaries hospitalized for the Hospital Readmissions Reduction Program's (HRRP's) priority conditions. Evidence suggests timely follow-up is associated with reduced risk of readmission, but it is unknown whether timely follow-up reduces disparities in readmission.

Objective

To assess whether follow-up within 7 days after discharge from a hospitalization reduces risk of readmission and mitigates identified readmission disparities.

Design

A retrospective cohort study using Cox proportional hazards models to estimate the associations between sociodemographic characteristics (race and ethnicity, dual-eligibility status, rurality, and area social deprivation), follow-up, and readmission. Mediation analysis was used to examine if disparities in readmission were mitigated by follow-up.

Participants

We analyzed data from 749,402 Medicare fee-for-service beneficiaries hospitalized for acute myocardial infarction, chronic obstructive pulmonary disease, heart failure, or pneumonia, and discharged home between January 1 and December 1, 2018.

Main measure

All-cause unplanned readmission within 30 days after discharge.

Key results

Post-discharge follow-up within 7 days of discharge was associated with a substantially lower risk of readmission (HR: 0.52, 95% CI: 0.52-0.53). Across all four HRRP conditions, beneficiaries with dual eligibility and beneficiaries living in areas with high social deprivation had a higher risk of readmission. Non-Hispanic Black beneficiaries had higher risk of readmission after hospitalization for pneumonia relative to non-Hispanic Whites. Mediation analysis suggested that 7-day follow-up mediated 21.2% of the disparity in the risk of readmission between dually and non-dually eligible beneficiaries and 50.7% of the disparity in the risk of readmission between beneficiaries living in areas with the highest and lowest social deprivation. Analysis suggested that after hospitalization for pneumonia, 7-day follow-up mediated nearly all (97.5%) of the increased risk of readmission between non-Hispanic Black and non-Hispanic White beneficiaries.

Conclusions

Improving rates of follow-up could be a strategy to reduce readmissions for all beneficiaries and reduce disparities in readmission based on sociodemographic characteristics.

Project description:ImportanceThe Centers for Medicare & Medicaid Services recently identified 30-day readmission after discharge from inpatient rehabilitation facilities as a national quality indicator. Research is needed to determine the rates and factors related to readmission in this patient population.ObjectiveTo determine 30-day readmission rates and factors related to readmission for patients receiving postacute inpatient rehabilitation.Design, setting, and patientsRetrospective cohort study of records for 736,536 Medicare fee-for-service beneficiaries (mean age, 78.0 [SD, 7.3] years) discharged from 1365 inpatient rehabilitation facilities to the community in 2006 through 2011. Sixty-three percent of patients were women, and 85.1% were non-Hispanic white.Main outcomes and measuresThirty-day readmission rates for the 6 largest diagnostic impairment categories receiving inpatient rehabilitation. These included stroke, lower extremity fracture, lower extremity joint replacement, debility, neurologic disorders, and brain dysfunction.ResultsMean rehabilitation length of stay was 12.4 (SD, 5.3) days. The overall 30-day readmission rate was 11.8% (95% CI, 11.7%-11.8%). Rates ranged from 5.8% (95% CI, 5.8%-5.9%) for patients with lower extremity joint replacement to 18.8% (95% CI, 18.8%-18.9%). for patients with debility. Rates were highest in men (13.0% [ 95% CI, 12.8%-13.1%], vs 11.0% [95% CI, 11.0%-11.1%] in women), non-Hispanic blacks (13.8% [95% CI, 13.5%-14.1%], vs 11.5% [95% CI, 11.5%-11.6%] in whites, 12.5% [95% CI, 12.1%-12.8%] in Hispanics, and 11.9% [95% CI, 11.4%-12.4%] in other races/ethnicities), beneficiaries with dual eligibility (15.1% [95% CI, 14.9%-15.4%], vs 11.1% [95% CI, 11.0%-11.2%] for no dual eligibility), and in patients with tier 1 comorbidities (25.6% [95% CI, 24.9%-26.3%], vs 18.9% [95% CI, 18.5%-19.3%] for tier 2, 15.1% [95% CI, 14.9%-15.3%] for tier 3, and 9.9% [95% CI, 9.9%-10.0%] for no tier comorbidities). Higher motor and cognitive functional status were associated with lower hospital readmission rates across the 6 impairment categories. Adjusted readmission rates by state ranged from 9.2% to 13.6%. Approximately 50% of patients rehospitalized within the 30-day period were readmitted within 11 days of discharge. Medicare Severity Diagnosis-Related Group codes for heart failure, urinary tract infection, pneumonia, septicemia, nutritional and metabolic disorders, esophagitis, gastroenteritis, and digestive disorders were common reasons for readmission.Conclusions and relevanceAmong postacute rehabilitation facilities providing services to Medicare fee-for-service beneficiaries, 30-day readmission rates ranged from 5.8% to 18.8% for selected impairment groups. Further research is needed to understand the causes of readmission.

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:ImportanceThe Improving Medicare Post-Acute Care Transformation (IMPACT) Act of 2014 mandated a quality measure of successful community discharge for postacute care services. Examining variation in performance nationally can help identify opportunities for improving patient-centered quality of care.ObjectiveTo examine US facility-level and geographic variation in rates of successful community discharges after inpatient rehabilitation.Design, setting, and participantsThis retrospective cohort study of Medicare claims data from December 31, 2013, through October 1, 2015, included 1154 inpatient rehabilitation facilities submitting claims to the Centers for Medicare & Medicaid Services and a total of 487 862 Medicare fee-for-service beneficiaries discharged from inpatient rehabilitation facilities. Analyses were performed from December 8, 2017, through September 11, 2018.Main outcomes and measuresSuccessful community discharge as defined for the Discharge to Community-Post-Acute Care Inpatient Rehabilitation Facility Quality Reporting Program measure. To be considered a successful community discharge, patients had to discharge from the inpatient rehabilitation facility to the community (ie, home or self-care) and remain there without experiencing an unplanned rehospitalization or dying within the following 31 days. Centers for Medicare & Medicaid Services specifications were followed to identify the cohort, define the outcome, and calculate risk-standardized facility and state rates.ResultsAmong the 487 862 patients included in the cohort, mean (SD) age was 76.4 (10.8) years, and 56.9% were female. The overall rate of successful community discharge after inpatient rehabilitation was 63.7% (95% CI, 63.6%-63.8%). Risk-standardized rates ranged from 42.9% to 83.6% across inpatient rehabilitation facilities. Two hundred sixteen facilities (18.7%) performed significantly better than the mean national rate and 203 (17.6%) performed significantly worse (P < .05). Risk-standardized state rates ranged from 55.9% to 73.3%. Rates were lowest in the Northeast (Massachusetts, 55.9%; New Hampshire, 57.0%) and highest in the West (Oregon, 70.3%; Hawaii, 73.3%).Conclusions and relevanceThe observed variation suggests opportunities exist for improving this important, patient-centered national quality measure. Future research is needed to identify the aspects of care delivery and the community services and supports that facilitate successful community discharge. These findings can be used to guide care improvement efforts and further improve the consistency and quality of postacute care.

Project description:ImportanceClinical trials play a critical role in the development of novel cancer therapies, and precise estimates of the frequency with which older adult patients with cancer participate in clinical trials are lacking.ObjectiveTo estimate the proportion of older adult Medicare Fee-for-Service (FFS) beneficiaries with cancer who participate in interventional cancer clinical trials, using a novel population-based methodology.Design, setting, and participantsIn this retrospective cohort study evaluating clinical trial participation among older adult patients with cancer from January 1, 2014, through June 30, 2020, claims data from Medicare FFS were linked with the ClinicalTrials.gov to determine trial participation through the unique National Clinical Trial (NCT) identifier. The proportion of patients with newly diagnosed or newly recurrent cancer in 2015 participating in an interventional clinical trial and receiving active cancer treatment from January 2014 to June 2020 was estimated. Data analysis was performed from November 18, 2020, to November 1, 2021.ExposuresPatients with cancer aged 65 years or older with Medicare FFS insurance, with and without active cancer treatment.Main outcomes and measuresEnrollment in clinical trials among all patients with cancer 65 years and older and among patients receiving active cancer treatments as defined by the presence of at least 1 NCT identifier corresponding to an interventional cancer clinical trial in Medicare claims.ResultsAmong 1 150 978 patients (mean [SD] age, 75.7 [8.4] years; 49.9% men and 50.1% women) with newly diagnosed or newly recurrent cancer in 2015, 12 028 (1.0%) patients had a billing claim with an NCT identifier indicating enrollment in an interventional cancer clinical trial between January 2014 and June 2020. In a subset of 429 343 patients with active cancer treatment, 8360 (1.9%) were enrolled in 1 or more interventional trials. Patients enrolled in a trial tended to be younger, male, a race other than Black, and residing in zip codes with high median incomes.Conclusions and relevanceFindings of this cohort study show that clinical trial enrollment among older adult patients with cancer remains low, with only 1.0% to 1.9% of patients with newly diagnosed or recurrent cancer in 2015 participating in an interventional cancer clinical trial as measured by the presence of NCT identifiers in Medicare claims. These data provide a contemporary estimate of trial enrollment, persistent disparities in trial participation, and only limited progress in trial access over the past 2 decades.

Project description:ImportanceAlthough enrollment in both hospice care and Medicare Advantage (MA) have grown substantially, little is known about the quality of hospice care received by MA beneficiaries relative to traditional Medicare fee-for-service (FFS) beneficiaries.ObjectiveTo compare hospice enrollment and the quality of hospices serving MA and FFS beneficiaries.Design, setting, and participantsThis population-based cross-sectional study used Medicare enrollment and claims data from January 1, 2018, through December 31, 2019, and Hospice Quality Reporting Program (HQRP) data released between November 1, 2020, and August 30, 2022, to compare the probability of enrolling in hospice before death and the probability of using high- vs low-quality hospices between MA and FFS beneficiaries. Two sample populations were assessed: (1) all Medicare beneficiaries who died in 2018 or 2019, and (2) all Medicare hospice enrollees in 2018 and 2019, excluding beneficiaries with hospice use in 2017. Data were analyzed between April 1, 2023, and April 30, 2024.ExposuresMA enrollment was assessed 6 months prior to death for decedents and in the month of hospice admission for hospice enrollees. MA beneficiaries were further classified by plan type: regular MA, special needs plan (SNP), and Medicare-Medicaid plan (MMP).Main outcomes and measuresFor decedents, the outcome of interest was the prevalence of any hospice use in the last 6 months of life. For hospice enrollees, the outcome of interest was 9 HQRP measures of hospice quality.ResultsData from 4 215 648 decedents (51.6% female; mean [SD] age, 80.1 [11.6] years) and 2 211 826 hospice enrollees (56.6% female; mean [SD] age, 82.4 [10.5] years) were included. In the decedent sample, beneficiaries enrolled in every type of MA plan were significantly more likely than beneficiaries enrolled in FFS to use hospice care in the last 6 months of life (regular MA beneficiaries were 3.4 percentage points more likely to use hospice; MA SNP beneficiaries, 2.4 percentage points; and MA MMP beneficiaries, 3.6 percentage points). Regular MA and FFS beneficiaries enrolled in hospices of similar quality. However, beneficiaries in SNPs and MMPs were significantly more likely than FFS beneficiaries to use hospices with inferior quality (eg, MA SNP beneficiaries were 4.3 [95% CI, 3.9-4.7] percentage points more likely to use a hospice with a low Consumer Assessment of Healthcare Providers and Systems (CAHPS) global rating, and MA MMP beneficiaries were 6.8 [95% CI, 6.0-7.7] percentage points more likely). When beneficiaries entered hospice from the same hospital or nursing home the results were attenuated: the MA SNP beneficiaries entering from the same hospital were 0.9 (95% CI, 0.5-1.4) percentage points more likely to use a hospice with a low CAHPS global rating, and MA MMP beneficiaries were 3.8 (95% CI, 2.4-5.1) percentage points more likely; MA SNP beneficiaries entering from the same nursing home were 2.8 (95% CI, 2.3-3.3) percentage points more likely to use a hospice with a low CAHPS global rating, and MA MMP beneficiaries were 1.9 (95% CI, 0.9-2.9) percentage points more likely. These results suggest that referral networks were an important mechanism of the hospice quality choice.Conclusions and relevanceThese findings suggest that policymakers should consider policies for MA programs that incentivize referrals to high-quality hospices and approaches to educating beneficiaries on identifying high-quality hospice care.
