Post-op readmission linked to delays in functional recovery
Margaret A. Pisani, M.D., M.P.H., from the Yale University School of Medicine in New Haven. Conn., and colleagues conducted a prospective cohort study involving 566 community-dwelling older adults (mean age, 77 ± 5 years) undergoing major elective surgery. The authors assessed readmission over 18 months using multiple interviews with participants and family members.
The researchers found that 45 percent of participants experienced 503 readmissions. Readmission correlated with delays in functional recovery in all physical function measures. Having two or more readmissions during 18 months correlated with a persistent and significantly elevated risk of dependence in instrumental activities of daily living and activities of daily living (relative risks, 1.8 and 3.3, respectively). There was a progressive increase in the degree of functional impairment with the number of readmissions. Readmission within two months after surgery correlated with delayed functional recovery to baseline by 18 months; readmission between 12 and 18 months correlated with loss of previously achieved functional recovery.
"Readmission after elective surgery may contribute to delays in functional recovery and persistent functional deficits in older adults," the authors write.
