How do you calculate medication errors per 1000 bed days?

To calculate medication errors per 1,000 bed days, first determine the total number of medication errors that occurred during a specific period. Next, calculate the total bed days by multiplying the number of occupied beds by the number of days they were occupied during that same period. Finally, divide the total number of medication errors by the total bed days and then multiply by 1,000 to get the rate per 1,000 bed days. The formula is: (Total Medication Errors / Total Bed Days) × 1,000.
