Thirty-day hospital readmissions for adults with and without HIV infection.

ABSTRACT: Risk-adjusted 30-day hospital readmission rate is a commonly used benchmark for hospital quality of care and for Medicare reimbursement. Persons living with HIV (PLWH) may have high readmission rates. This study compared 30-day readmission rates by HIV status in a multi-state sample with planned subgroup comparisons by insurance and diagnostic categories.Data for all acute care, nonmilitary hospitalizations in nine states in 2011 were obtained from the Healthcare Costs and Utilization Project. The primary outcome was readmission for any cause within 30 days of hospital discharge. Factors associated with readmission were evaluated using multivariate logistic regression.A total of 5?484?245 persons, including 33?556 (0.6%) PLWH, had a total of 6?441?695 index hospitalizations, including 45?382 (0.7%) among PLWH. Unadjusted readmission rates for hospitalizations of HIV-uninfected persons and PLWH were 11.2% [95% confidence interval (CI) 11.2, 11.2%] and 19.7% (95% CI 19.3, 20.0%), respectively. After adjustment for age, gender, race, insurance, and diagnostic category, HIV infection was associated with 1.50 (95% CI 1.46, 1.54) times higher odds of readmission. Predicted, adjusted readmission rates were higher for PLWH within every insurance category, including Medicaid [12.9% (95% CI 12.8, 13.0%) and 19.1% (95% CI 18.4, 19.7%) for HIV-uninfected persons and PLWH, respectively] and Medicare [13.2% (95% CI 13.1, 13.3%) and 18.0% (95% CI 17.4, 18.7%), respectively], and within every diagnostic category.HIV infection is associated with significantly increased readmission risk independent of demographics, insurance, and diagnostic category. The 19.7% 30-day readmission rate may serve as a preliminary benchmark for assessing quality of care of PLWH. Policy-makers may consider adjusting for HIV infection when calculating a hospital's expected readmission rate.

Project description:ImportanceThe Medicare Hospital Readmissions Reduction Program (HRRP) has disproportionately penalized hospitals that treat many black patients, which could worsen health outcomes in this population.ObjectiveTo determine whether short-term mortality rates increased among black and white adults 65 years and older after initiation of the HRRP and whether trends differed by race.Design, setting, and participantsIn a cohort study using an interrupted time-series analysis conducted from March 15, 2018, to January 23, 2019, in 3263 eligible acute care hospitals nationally, risk-adjusted mortality rates observed after Medicare started to impose penalties (October 1, 2012, to November 30, 2014) were compared with projections based on pre-HRRP trends (January 1, 2007, to March 31, 2010) among adults 65 years and older with acute myocardial infarction (AMI), heart failure (HF), or pneumonia. Observed-to-projected differences were then compared between racial groups.ExposuresHospital discharge during pre-HRRP and HRRP penalty periods.Main outcomes and measuresThirty-day postdischarge all-cause mortality.ResultsIn the 3263 acute care hospitals included in the analysis, black patients (627?373 index discharges) were more likely than white patients (5?845?130 index discharges) to be younger (mean [SD] age, 77.8 [8.3] vs 80.5 [8.2] years; P?<?.001), women (60.5% vs 53.7%; P?<?.001), dually covered by Medicare and Medicaid (45.7% vs 17.2%; P?<?.001), and treated at a penalized hospital (AMI, 82.8%; HF, 83.8%; and pneumonia, 82.6% vs 69.6%; 73.3%; and 71.7%; all P?<?.001). Pre-HRRP mortality rates for black vs white patients were 7.04% (95% CI, 6.75% to 7.33%) vs 7.47% (95% CI, 7.37% to 7.57%) for AMI, 6.69% (95% CI, 6.56% to 6.82%) vs 8.56% (95% CI, 8.48% to 8.64%) for HF, and 8.08% (95% CI, 7.88% to 8.27%) vs 8.27% (95% CI, 8.19% to 8.35%) for pneumonia. By the HRRP penalty period, observed mortality for AMI decreased more, relative to projections, among black than white patients (difference-in-differences, -1.65 percentage points; 95% CI, -3.19 to -0.10; P?=?.04). For HF, mortality increased relative to projections among white patients but not among black patients; however; mortality trends did not differ by race (difference-in-differences, -0.37 percentage points; 95% CI, -1.08 to 0.34; P?=?.31). For pneumonia, observed mortality was similar to projections in both racial groups, and trends did not differ by race (difference-in-differences, -0.54 percentage points; 95% CI, -1.66 to 0.59; P?=?.35). At both penalized and nonpenalized hospitals, mortality trends were similar or decreased more among black patients than white patients.Conclusions and relevanceIn this study of patients 65 years and older, short-term postdischarge mortality did not appear to increase for black patients under the HRRP, suggesting that certain value-based payment policies can be implemented without harming black populations. However, mortality seemed to increase for white patients with HF and this situation warrants investigation.
