Medications and diagnoses in relation to falls in a long-term care facility.

The association between falls, drugs, and diagnoses in elderly residents of a long-term care facility was explored using case-control methodology. The odds of being a faller rather than a control were significant (P less than .01) for those taking antidepressants, sedatives/hypnotics, or vasodilators, and for those with osteoarthritis or depression. When drug/diagnosis subgroups were examined, these same drug classes and diagnoses had high-odds ratios in the largest numbers of subgroups. In general, risk of falling appeared to be more strongly associated with drugs than with diagnoses.
