OBJECTIVE: Readmission is used as a quality indicator and is the primary target outcome for disease-modifying therapy (DMT) for multiple sclerosis (MS). However, data on readmissions for patients with MS are limited.
METHODS: Using the US Nationwide Readmissions Database, we performed a retrospective cohort study of adults hospitalized for MS in 2014. Primary study outcomes were within 30- and 90-day readmissions. Descriptive analyses compared patient, clinical, and hospital variables readmission status. Multivariable logistic regression models estimated the associations between these variables and readmission.
RESULTS: Of 16,629 individuals meeting the study criteria, most were women (73.7%), aged 35-54 years (48.0%), and Medicare program participants (36.8%). In total, 49.7% of inpatients with MS had 1-2 comorbid medical conditions and 23.7% had 3 or more. Having 3 or more comorbidity conditions associated with increased adjusted odds of the 30-day readmission (adjusted odds ratio [AOR] 1.92, 1.34-2.74). Anemia (AOR 1.62, 1.22-2.14), rheumatoid arthritis/collagen vascular diseases (AOR 2.20, 1.45-3.33), congestive heart failure (AOR 2.43, 1.39-4.24), chronic pulmonary disease (AOR 1.35, 1.02-1.78), diabetes with complications (AOR 2.27, 1.45-3.56), hypertension (AOR 1.25, 1.03-1.53), obesity (AOR 1.35, 1.05-1.73), and renal failure (AOR 1.68, 1.06-2.67) were associated with the 30-day readmission. Medicare insurance and nonroutine discharge were also associated with readmission, whereas patient characteristics (sex, age, and socioeconomic status) were not. The most frequent (26.7%) reason for readmission was multiple sclerosis. Ninety-day analyses produced similar findings.
CONCLUSIONS: Comorbid diseases were associated with the readmission for persons with multiple sclerosis. Evaluations of the real-world effectiveness for DMTs in reducing hospitalizations in patients with MS may need to consider comorbid disease burden and management.
