Nursing Homes post-acute care long-term care medications prescribing deprescribing Pharmaceutical agents are a valuable resource to assist in the care of older persons. Their use in post-acute and long-term care settings is particularly notabledfor example, the proportion of nursing home residents taking 9 or more medications increased from 18% in the mid-1990s to 40% less than 15 years later. 1,2 Average drug counts are similarly high around the world, although there is considerable variation in use between settings and countries. 3,4 High medication use occurs despite the fact that persons with advanced age and multimorbidity are particularly susceptible to drug adverse effects due to physiological changes such as declines in hepatic and renal clearance. Further, the probability of deleterious drug interactions rises exponentially as the number of medications increases. 5 Why are so many drugs administered in post-acute and long-term care, and why does the number keep rising? One reason is because new and better agents have been developed for a variety of conditions common in nursing homes, which relieve or prevent morbidity and delay mortality. Many of these newer medications, such as bisphosphonates for fracture prevention, angiotensin-converting enzyme inhibitors for diabetic renal protection, and beta blockers for coronary artery disease, have strong data in the nursing home literature supporting their use. Other reasons for increasing drug lists, however, are less clearly good for patients. In some cases,The authors declare no conflicts of interest.
