Table 2 Measures of absenteeism due to malaria.
From: Effect of malaria on productivity in a workplace: the case of a banana plantation in Zimbabwe
Parameter | How it was determined |
|---|---|
Incidence of absence | Is the number of days lost in one spell of the worker category divided by total days of that worker category × 100 |
Absence frequency | Total number of spells in 5 months |
Absenteeism frequency rate | Average number of spells per absentee (total number of malaria episodes divided by total number of absentees) |
Total duration (in days) of spells of absenteeism | Total number of days lost due to malaria |
Severity rate | Average duration of spells (total number of days lost due to malaria divided by total number of malaria episodes) |
Incapacity rate | Mean number of days lost per absentee (total number of days lost due to malaria divided by the number of absentees) |
Number of listed public holidays | These were calculated from the calendar for each month as gazetted by the Government of Zimbabwe |
Number of working days | All working days (5.5 days per week) were added up for 5 months |
Total number of absent days by workers | Absence frequency × average duration of spells (spells × severity rate) |
Total number of scheduled working days for all workers | All working days excluding holidays in 5 months × total workers |
Absenteeism rate | (Total number of absent days divided by total scheduled days) × 100 |
