Are high-care nursing home residents at greater risk of unplanned hospital admission than other elderly patients when exposed to Beers potentially inappropriate medications?

Abstract

Aim: To compare the risk of unplanned hospitalization in high-care nursing home residents taking Beers potentially inappropriate medications (PIM) against that of other elderly. Methods: Using an enhanced case-time-control design and conditional logistic regression applied to the pharmaceutical claims and other linked data of 245436 Western Australians aged ≥65 years (1993-2005), the study derived odds ratios for unplanned hospitalization in each group, from which attributable fractions, numbers, proportions and rates of PIM-related admissions were derived. Results: Overall, 383150 unplanned hospitalizations were identified. PIM exposure was associated with a similar proportional increase in..
