In a surgery department's monthly case review with 10 records meeting criteria and six additional records that did not, what is the denominator when calculating the incidence rate?

  1. 10

  2. 16

  3. 4

  4. 6

The correct answer is: 10

When calculating the incidence rate, the denominator represents the total population at risk of the event being studied. In this scenario, the monthly case review included 10 records that met the criteria and were part of the population at risk. The six additional records that did not meet the criteria are not included in the calculation because they are not part of the population at risk for the event being studied. Therefore, the correct denominator when calculating the incidence rate in this case is 10, as it includes the number of records meeting the criteria.
