ABSTRACT
BACKGROUND: Sickle cell disease (SCD) is the most common inherited blood disorder, affecting primarily Black and Hispanic individuals. In 2016, 30-day readmissions incurred 95,445 extra days of hospitalization, $152 million in total hospitalization costs, and $609 million in total hospitalization charges.
OBJECTIVES: 1) To estimate hospital readmissions within 30 days among patients with SCD in the State of California. 2) Identify the factors associated with readmission within 30 days for SCD patients in California.
METHODS: We conducted a retrospective observational study of adult SCD patients hospitalized in California between 2005 and 2014. Descriptive statistics and logistic regression models were used to examine significant differences in patient characteristics and their association with hospital readmissions.
RESULTS: From 2,728 individual index admissions, 70% presented with single admission, 10% experienced one readmission, and 20% experienced ≥ two readmissions within 30 days. Significant predictors associated with zero vs. one readmission were male gender (OR=1.37, CI: 1.06-1.77), Black ethnicity (OR=3.27, CI: 1.71-6.27) and having Medicare coverage (OR=1.89, CI: 1.30-2.75). Lower likelihood of readmission was found in those with a Charlson Comorbidity index of three or more (OR=0.53, CI: 0.29-0.97). For zero vs. ≥ two readmissions, significant predictors were male gender (OR=1.43, CI: 1.17-1.74), Black ethnicity (OR=6.90, CI: 3.41-13.97), Hispanic ethnicity (OR=2.33, CI: 1.05-5.17), Medicare coverage (OR=3.58, CI: 2.68-4.81) and Medi-Cal coverage (OR=1.70, CI: 1.31-2.20). Lower likelihood for having two or more readmissions were associated with individuals aged 65+ (OR=0.97, CI: 0.96-0.98) and those with self-payment status (OR=0.32, CI: 0.12-0.54).
CONCLUSIONS: In California, male, Black, and Hispanic patients, as well as those covered by Medicare or Medi-Cal, were found to have an increased risk of hospital readmissions. Redirecting outpatient goals to address these patient populations and risk factors is crucial for reducing readmission rates.
