Abstract
Objectives
the aims of the present study were: (1) investigate the prevalence and association of polypharmacy and pre-frailty or frailty in a middle-income country sample of older adults; and (2) evaluate the prevalence of potential inappropriate prescription (PIP) and its association with pre-frailty or frailty.
Design
Cross-sectional observational study.
Setting
Outpatient center at a university-based hospital in the state of São Paulo, Brazil.
Participants
629 older adults from both sexes evaluated between June 2014 and July 2016.
Measurements
Frailty was identified through the FRAIL scale. All medications received were analyzed by research staff. Presence of PIP was evaluated according to the 2015 updated Beers list. Binary logistic regression tested the association between 4 definitions of polypharmacy (≥ 3, 4, 5, and 6 drugs), and presence of PIP, and the dependent variable pre-frailty and frailty.
Results
15.7% of participants were frail. Polypharmacy was present in 219 (34.8%), and PIP was observed in 184 (29.3%) older adults. All definitions of polypharmacy were significantly associated with frailty (OR between 2.05 to 2.34, p < 0.001). Polypharmacy with 4 or 5 or more drugs were associated with pre-frailty (OR 1.53 and 1.47, respectively). PIP was not associated with frailty (OR 1.47, p = 0.149).
Conclusions
Several definitions of polypharmacy were associated with frailty, but only two were associated with pre-frailty. The presence of PIP was not associated with pre-frailty or frailty.
