The drug consumptions of 2228 residents in nursing homes aged 65 years and over were investigated and related to accidental falls during a period of seven months. 95% of the residents received treatment with one or more drugs and 33% with six or more drugs. The risk of accidental falls was significantly increased in persons receiving hypnotics, psychomarmaca and anti-Parkinson medicine. Individuals receiving diuretics, particularly thiazides, were less at risk for accidental falls. This investigation revealed an increased risk of falls particularly when residents were receiving treatment with a short-term hypnotic (Triazolam). It is recommended that this finding should be investigated further.
