Substantial hospital level variation in all-cause readmission rates among Medicare beneficiaries with serious mental illness.
This study’s purpose was to examine the variation across hospitals in readmissions for patients with serious mental illness (SMI) and differences in the characteristics of hospitals with the highest and lowest readmission rates. A cross-sectional analysis was conducted of pooled inpatient claims from 2013-2016. The 5% sample of fee-for-service Medicare beneficiaries included patients with SMI. The authors identified 2066 hospitals with at least 30 index admissions for Medicare beneficiaries with SMI. Factors most strongly associated with increased risk of readmission included substance use disorder and end stage renal disease. Hospital readmission rates ranged from 7.05% to 15.24%. Hospitals with the lowest adjusted readmission rates were more likely to be teaching hospitals and located in the South or Midwest.

Psychotropic medication use among Medicare beneficiaries following traumatic brain injury.
The researchers characterized psychotropic medication use before and after traumatic brain injury (TBI) hospitalization among older adults. They found that average monthly prevalence of psychotropic medication use among all patients hospitalized for TBI was 44.8 percent; antidepressants constituted 73 percent. Following TBI, psychotropic medication use increased slightly.
