Aim: To investigate if older adults using multiple drugs have an increased risk of rehospitalization and mortality after hospital discharge. Methods: This was a prospective cohort study carried out in acute care hospitals. The primary outcomes of the study were rehospitalization and mortality within 1 year after discharge from acute care hospitals. The study population was categorized in two groups according to the number of drugs prescribed at hospital discharge: no polypharmacy (<8 drugs) and polypharmacy (≥8 drugs). Results: The mean age of 480 participants was 78.6 ± 6.8 years ,and half of them (n = 238; 49.6%) were using multiple drugs (≥8 drugs). Overall, 65 out of 242 participants (26.9%) in the no polypharmacy group and 92/238 (39.1%) in the polypharmacy group were rehospitalized (P = 0.004), and 15 out of 242 (6.2%) in the no polypharmacy and 23 out of 238 (9.7%) in the polypharmacy group died during the 1 year follow up (P = 0.16). After adjusting for potential confounders, participants in the polypharmacy group had an increased risk of 1-year rehospitalization as compared with those in the no polypharmacy group (RR = 1.81, 95% CI = 1.18–2.75). No significant association was observed between mortality and polypharmacy. Conclusions: Older persons using multiple drugs are at increased risk of rehospitalization. Further studies are required to assess the impact of programs aimed at reducing polypharmacy on health outcomes

Abstract

Aim: To investigate if older adults using multiple drugs have an increased risk of rehospitalization and mortality after hospital discharge. Methods: This was a prospective cohort study carried out in acute care hospitals. The primary outcomes of the study were rehospitalization and mortality within 1 year after discharge from acute care hospitals. The study population was categorized in two groups according to the number of drugs prescribed at hospital discharge: no polypharmacy (<8 drugs) and polypharmacy (≥8 drugs). Results: The mean age of 480 participants was 78.6 ± 6.8 years ,and half of them (n = 238; 49.6%) were using multiple drugs (≥8 drugs). Overall, 65 out of 242 participants (26.9%) in the no polypharmacy group and 92/238 (39.1%) in the polypharmacy group were rehospitalized (P = 0.004), and 15 out of 242 (6.2%) in the no polypharmacy and 23 out of 238 (9.7%) in the polypharmacy group died during the 1 year follow up (P = 0.16). After adjusting for potential confounders, participants in the polypharmacy group had an increased risk of 1-year rehospitalization as compared with those in the no polypharmacy group (RR = 1.81, 95% CI = 1.18–2.75). No significant association was observed between mortality and polypharmacy. Conclusions: Older persons using multiple drugs are at increased risk of rehospitalization. Further studies are required to assess the impact of programs aimed at reducing polypharmacy on health outcomes
