Distribution of the rate of falls in nursing home residents with respect to a psychotropic drug change. Negative values indicate days prior to the drug change, whereas positive values indicate days after the drug change. The number of falls is presented above each bar graph. Fall risk was greatest: 1) 4 days prior to the drug change, 2) on the day of the drug change through 2 days after the drug change, 3) 5–6 days after the drug change. For comparison, we present A) the annual rate of falls among psychotropic users with a drug change during one-year follow-up, B) the annual rate of falls among psychotropic users without a drug change during one-year follow-up.
