Title:  Using Progression of Modified Functional Independent Measure as an Indicator of Readmission Risk to Acute Hospital for Patients at a Skilled Nursing Facility

Summary:  We determined whether modified functional independent measure (mFIM) score progression is a useful indicator of risk for readmission to acute hospital in patients at skilled nursing facility. This was a cross-sectional study of 198 patients in consecutive admission over 5 months at a skilled nursing facility. mFIM scores were performed by physical therapist and an occupational therapist  on 189 patients.

mFIM scores were used to determine patient functional progress in treatment among different disposition groups. The difference between the last and first mFIM compared to the length of stay rates the effectiveness of the rehabilitation. The groups are divided by their disposition of discharge: home (n=123), readmit (n=24), custodial nursing facility (n=18), board and care (n=10), assisted living (n=8), expired (n=3), and elective surgery (n=3). Using ANOVA, with a p < 0.001, the mean ∆mFIM of the readmit group was 0.771 (95% Cl, -1.397 – 2.938), while the home group was 5.106 (95% CI, 4.239 – 5.972). The mean length of stay of the readmit group was 8.792 days (95% Cl, 6.138 – 11.445) and the home group was 13.894 days (95% Cl, 12.743 – 15.046). Comparing the groups, the ∆mFIM of the readmit group was significantly less than that of the home group. Slow functional progress in skilled nursing facility is a useful predictor for readmission to acute hospital care. The mFIM score trends require larger sample size to have statistically significant results for the different groups.
