Potentially serious alcohol-medication interactions and falls in community-dwelling older adults: a prospective cohort study

OBJECTIVE: To investigate the association between potentially serious alcohol-medication interactions (POSAMINO criteria), hypothesised to increase the risk of falls in older adults, and falls in community-dwelling older adults at two and 4 years follow-up.

DESIGN: A prospective cohort study. SETTING: The Irish Longitudinal Study on Ageing.

SUBJECTS: A total of 1,457 community-dwelling older adults aged >/=65 years, with a complete alcohol and regular medication data to allow for the application of the POSAMINO criteria.

OUTCOMES: Self-reported falls at 2 and 4 years follow-up, any falls (yes/no), injurious falls (yes/no) and number of falls (count variable).

RESULTS: The number of participants who reported falling since their baseline interview at 2 and 4 years were 357 (24%) and 608 (41.8%), respectively; 145 (10%) reported an injurious fall at 2 years and 268 (18%) at 4 years. Median (IQR) number of falls was 1 (1-2) at 2 years and 2 (1-3) at 4 years. Exposure to CNS POSAMINO criteria, hypothesised to increase the risk of falls due primarily to increased sedation, was associated with a significantly increased risk for falling (adjusted relative risk (RR) 1.50, 95% confidence interval (CI) 1.21-1.88) and for injurious falls (adjusted RR 1.62, 95% CI: 1.03-2.55) at 4 years. These equate to an absolute risk of 19% for falling (95% CI: 5-33%) and 8% for injurious falls (95% CI, 4-20%) at 4 years.

CONCLUSIONS: Assessment and management strategies to prevent falls in community-dwelling older adults should consider patients' alcohol consumption alongside their assessment of patient medications, particularly among those receiving CNS agents.
