Extent and quality of drug use in community-dwelling people aged ≥75 years: A Swedish nationwide register-based study

Aims: It is important for district nurses and other health professionals in primary care to gain more insight into the patterns and quality of drug use in community-dwelling older people, particularly in 75-year-olds, who have been the target of preventive home visits. This study aimed to examine the extent and quality of drug use in community-dwelling older people and to compare drug use in 75-year-olds with that of older age groups. Methods: Data from 2013 on people aged ≥75 years were obtained from the Swedish Prescribed Drug Register. Those living in the community (671,940/739,734 people aged ≥75 years) were included in the study. Quality of drug use was assessed by using a selection of indicators issued by the Swedish National Board of Health and Welfare. Results: The prevalence of polypharmacy and of many drug groups increased with age, as did several indicators of inappropriate drug use. However some drug groups, as well as inappropriate drugs, were prevalent in 75-year-olds and declined with age, for example diabetes drugs, drugs with major anticholinergic effects and nonsteroidal anti-inflammatory drugs. Conclusions: The substantial use of some drugs as early as 75 years of age confirms the value of including drug use as a topic in preventive home visits to 75-year-olds. The finding that polypharmacy and many measures of inappropriate drug use increased with age in community-dwelling older people also underscores the importance of district nurses’ role in continuing to promote safe medication management at higher ages.
