1) Assess the number of deaths in a given population during a specified time period.
2) Divide the number of deaths by the population at the mid-point of the time period multiplied by the number of days in the time period. For example, 120 deaths / (80,000 people multiplied by a 30 day period).
3) Multiply the number by 10,000 to gain the number of deaths per 10,000 persons per day. For example, (120 / (80,0000 x 30)) x 10,000. In this example, CRM is 0.5 persons per 10,000 persons per day.
