Impaired Functional Status at Discharge Ups Readmission
(HealthDay News) — Functional status at admission from an acute care hospital to an inpatient rehabilitation facility correlates with acute care readmission, according to a study published in the May issue of the Journal of Hospital Medicine.
Erik H. Hoyer, MD, from Johns Hopkins University in Baltimore, and colleagues conducted a retrospective cohort study involving 9,405 patients admitted from an acute care hospital to an inpatient rehabilitation facility. Functional status was assessed at admission to the rehabilitation facility by the Functional Independence Measure (FIM) score and patients were categorized into low, middle, or high functional status. The correlation between functional status and readmission to an acute care hospital within 30 days of acute care discharge was assessed.
The researchers found that 13% of the cohort were readmitted. The FIM score correlated significantly with readmission for low and middle versus high FIM score category (adjusted odds ratios, 3.0 and 1.5, respectively; both P<0.001). The association persisted across diagnostic categories. The highest readmission rate was seen for medical patients with low functional status (29%), with an adjusted odds ratio of 3.2 for readmission versus medical patients with high FIM scores.
"Reducing functional status decline during acute care hospitalization may be an important strategy to lower readmissions," the authors write.
