Abstract
Background: Schizophrenia and psychotic disorders (SPDs)-related hospitalizations are the second leading cause of 30-day readmission. This study assessed the effect of patient and hospital-level factors on readmission costs following index hospital discharges for SPDs.
Methods: 2014 Nationwide Readmissions Database was used to identify SPD-related discharges between January 1, 2014, and November 30, 2014. Multivariable logistic regression was used to estimate patient and hospital-level predictors for readmissions. A two part model was used to estimate the predictors of readmission and associated cost for index hospital discharges with SPDs.
Results: A total of 77 625 of 343 579 (22%) index hospital discharges for SPDs resulted in readmissions. The average index and readmission costs were $9285 and $8593, respectively. Being 25 to 44 years old (odds ratio: 1.14), with nonmental comorbidities (odds ratio: 1.52), and admitted in private hospitals (odds ratio: 1.24) had significantly higher odds of readmission rates. Being males ($105), 25 to 44 years of age ($99), urban residents ($312), Medicare enrollees ($713 over privately insured), high-income area residents ($393), having multiple comorbidities ($923), and those admitted in large metropolitan ($680) and government-owned hospitals ($417) had higher costs of readmission.
Conclusion: The high SPD-related readmission rates can be reduced by providing integrated behavioral health services for this high-risk cohort.
