Abstract
BACKGROUND
Polypharmacy is a common problem amongst the elderly population. The complexity of the drug regimen refers not only to a simple medication count, but also to the number of daily doses, frequency, and special instructions given for their use. Medication regimen complexity may affect health outcomes, including an increase in hospitalization rates, drug non-adherence, and mortality rates.
AIM
To assess whether the admission medication regimen complexity index score is associated with rehabilitation outcomes in hip fracture patients; secondary- to assess whether changes in the medication regimen complexity index scores during rehabilitation are associated with rehabilitation outcomes.
METHOD
A retrospective study of 336 hip fracture patients admitted to a post-acute rehabilitation hospital. Primary rehabilitation outcome was assessed via the discharge functional independence measure score. Secondary outcomes included functional independence measure score changes, length of stay and discharge destination.
RESULTS
Patients with low admission medication regimen complexity index scores attained significantly higher admission and discharge motor functional independence measure scores (40.1 vs. 37.1, p = 0.044; 57.1 vs. 52.9, p = 0.014, respectively), a higher motor functional independence measure score effectiveness (36.1 vs. 31.3, p = 0.030) and a higher rate of favorable motor functional independence measure effectiveness score (58.1% vs. 42.0%, p = 0.004). A multiple linear regression analysis revealed that the admission medication regimen complexity index score was not associated with the discharge functional independence measure score (standardized coefficient = - 0.058; p = 0.079).
CONCLUSION
A high medication regimen complexity which usually implies severe comorbidity should not be considered a barrier for the rehabilitation of older patients.
