Is social capital protective against hospital readmissions?

BACKGROUND: To evaluate the association between social capital and 30-day readmission to the hospital among Medicare beneficiaries overall, beneficiaries with dementia and related memory disorders, and beneficiaries with dual eligibility for Medicaid. METHODS: Using Health and Retirement Study (HRS) data linked with 2008-2015 Medicare claims from traditional Medicare beneficiaries hospitalized during the study period (1246 unique respondents, 2212 total responses), we examined whether dementia and related memory disorders and dual eligibility were associated with social capital. We then estimated a multiple regression model to test whether social capital was associated with a reduced likelihood of readmission. RESULTS: Dementia was associated with an - 0.241 standard deviation (sd) change in social capital (95% CI: - 0.378, - 0.103), dual eligibility with a - 0.461 sd change (95% CI: - 0.611, - 0.310), and the occurrence of both was associated with an additional - 0.236 sd change (95% CI: - 0.525, - 0.053). 30-day readmission rates were 14.47% over the study period. In both adjusted and unadjusted models, social capital was associated with small and nonsignificant differences in 30-day readmissions. These effects did not vary across dementia status and socioeconomic status. CONCLUSIONS: Dementia and dual eligibility were associated with lower social capital, but social capital was not associated with the risk of readmission for any population.

Changes in hospital safety following penalties in the US Hospital Acquired Condition Reduction Program: retrospective cohort study.

OBJECTIVE: To evaluate the association between hospital penalization in the US Hospital Acquired Condition Reduction Program (HACRP) and subsequent changes in clinical outcomes. DESIGN: Regression discontinuity design applied to a retrospective cohort from inpatient Medicare claims. SETTING: 3238 acute care hospitals in the United States. PARTICIPANTS: Medicare fee-for-service beneficiaries discharged from acute care hospitals between 23 July 2014 and 30 November 2016 and eligible for at least one targeted hospital acquired condition (n=15 470 334). INTERVENTION: Hospital receipt of a penalty in the first year of the HACRP. MAIN OUTCOME MEASURES: Episode level count of targeted hospital acquired conditions per 1000 episodes, 30 day readmissions, and 30 day mortality. RESULTS: Of 724 hospitals penalized under the HACRP in fiscal year 2015, 708 were represented in the study. Mean counts of hospital acquired conditions were 2.72 per 1000 episodes for penalized hospitals and 2.06 per 1000 episodes for non-penalized hospitals; 30 day readmissions were 14.4% and 14.0%, respectively, and 30 day mortality was 9.0% for both hospital groups. Penalized hospitals were more likely to be large, teaching institutions, and have a greater share of patients with low socioeconomic status than non-penalized hospitals. HACRP penalties were associated with a non-significant change of -0.16 hospital acquired conditions per 1000 episodes (95% confidence interval -0.53 to 0.20), -0.36 percentage points in 30 day readmission (-1.06 to 0.33), and -0.04 percentage points in 30 day mortality (-0.59 to 0.52). No clear patterns of clinical improvement were observed across hospital characteristics. CONCLUSIONS: Penalization was not associated with significant changes in rates of hospital acquired conditions, 30 day readmission, or 30 day mortality, and does not appear to drive meaningful clinical improvements. By disproportionately penalizing hospitals caring for more disadvantaged patients, the HACRP could exacerbate inequities in care.
