“Potentially inappropriate medications (PIMs)” are treatments that sometimes pose risks that outweigh their benefits, particularly for people who are 65 or older. About 20 to 60 percent of older adults take medicines that may be potentially inappropriate. That can increase the risk for being hospitalized, needing to visit the emergency department, having poor quality of life, and/or experiencing a harmful reaction.
When older adults are hospitalized for medical reasons or for surgery, they often go home with prescriptions for treatments that may be different from those they were taking beforehand. These treatments may include PIMs. Until now, however, few studies have examined how PIMs affect older adults when prescribed at the time of their hospital discharge.
A team of researchers recently designed a study to learn more about this important issue. They examined information from medical and surgical patients to evaluate the association of PIMs (both the ones the patients had been taking earlier as well as those newly prescribed at their hospital discharge) with the risk of four outcomes. The outcomes were harmful drug problems, emergency department visits, readmission to the hospital, and death after hospital discharge. The study was published in the Journal of the American Geriatrics Society. Continue reading
