Results - Event Rates

Text Description is below the image.
  • Adverse drug events
    • Events: 815
    • Rate: 9.8 per 100 resident-months
  • Preventable adverse drug events
    • Events: 338
    • Rate: 4.1 per 100 resident-months


In other words, if you have 100 residents, 2 events per month. Approximately half of the events we found were judged preventable—high rate.
