  • Description:
    Background: There is a need to examine health care utilization of individuals with the rare conditions muscular dystrophies, spina bifida, and fragile X syndrome. These individuals have a greater need for health care services, particularly inpatient admissions. Prior studies have not yet assessed 30-day all-cause readmission rates. Objective: To estimate 30-day hospital readmission rates among individuals with three rare conditions. Hypothesis: Rare conditions patients will have a higher 30-day all-cause readmission rate than those without. Methods: Data from three sources (2007–2014) were combined for this case-control analysis. A cohort of individuals with one of the three conditions was matched (by age in 5 year age groups, gender, and race) to a comparison group without a rare condition. Inpatient utilization and 30-day all-cause readmission rates were compared between the two groups. Logistic regression analyses compared the odds of a 30-day all-cause readmission across the two groups, controlling for key covariates. Results: A larger proportion in the rare condition group had at least one inpatient visit (46.1%) vs. the comparison group (23.6%), and a higher 30-day all-cause readmission rate (Spina Bifida-46.7%, Muscular Dystrophy-39.7%, and Fragile X Syndrome-35.8%) than the comparison group (13.4%). Logistic regression results indicated that condition status contributed significantly to differences in readmission rates. Conclusions: Higher rates of inpatient utilization and 30-day all-cause readmission among individuals with rare conditions vs. those without are not surprising, given the medical complexity of these individuals, and indicates an area where unfavorable outcomes may be improved with proper care coordination and post discharge care.
