[The indicator »drugs that should be avoided in older people« from a medical perspective – an analysis with the patient in focus].

The drug-specific indicator »drugs that should be avoided in older people«, defined by the National Board of Health and Welfare of Sweden, is part of a large set of indicators of potentially inappropriate prescribing used for benchmarking in health care and in research. In this study, 149 consecutive primary care patients (75-99 years of age, 62 percent female, 0-20 drugs in the medication list) were included. Their medication lists were screened for potentially inappropriate drugs according to the indicator at issue, including long-acting benzodiazepines, drugs with anticholinergic action, tramadol, propiomazine, codeine, and glibenclamide. Medically justified actions related to these drugs were determined by two specialist physicians in consensus. In all, 29 patients had 32 drugs listed in the indicator, 7 of which, in 6 patients, were deemed relevant to act upon before the next regular physician visit, e.g. the annual control of chronic conditions. For the remaining 25 drugs, in 23 patients, no such related action was medically justified prior to the next regular visit. Using the area under the receiver operating characteristic (ROC) curve, the indicator did not outperform chance to identify inadequately managed drug treatment, defined as the consensus decision by two specialist physicians that some action related to the full medication could be medically justified prior to the next regular visit: 0.56 (95% CI: 0.46-0.66). In conclusion, the indicator »drugs that should be avoided in older people« did not warrant action from a medical perspective for four out of five patients, and could not differentiate between adequately and inadequately managed drug treatment.
