Key Findings
Almost half of adults hospitalized in Massachusetts acute care hospitals had at least one comorbid behavioral health condition, representing a majority of discharges (54%) in SFY 2020.
Patients with any behavioral health comorbidity had inpatient stays that were, on average, 1.4 days longer than patients with no behavioral health comorbidity (6.0 days vs. 4.6 days).
Readmission rates for patients with any behavioral health comorbidity were nearly double the readmission rates for patients without any comorbid behavioral health condition (20.6% vs. 10.6%).
From April to June 2020, among discharges with a COVID-19 diagnosis, the presence of a comorbid behavioral health condition was associated with a readmission rate 2.2 times higher than discharges without a behavioral health condition (21.2% vs. 9.6%).
