Annual per capita productivity loss estimates across three methods for total sample (n = 325)
| Compensation | Disruption correction | Friction correction | ||
|---|---|---|---|---|
| Productivity loss | ||||
| Per capita productivity costs | Mean (SD) | 617 (75)* | 649 (78)* | 316 (58)* |
| Median (CI)+ | 611 (524 719) | 643 (553 757) | 309 (246 396) | |
| Ratio ++ | NA | 1.05 | 0.50 | |
| Absenteeism loss | ||||
| Per capita absenteeism days | Mean (SD) | 3 (6) | 3 (6) | 1 (3) |
| Median (CI)+ | 2 (1 3) | 2 (1 3) | 1 (0 2) | |
| Ratio++ | NA | 1.00 | 0.42 | |
| Per capita absenteeism costs | Mean (SD) | 96 (210) | 128 (277) | 62 (152) |
| Median (CI)+ | 71(26 109) | 94 (36 154) | 36 (3 101) | |
| Ratio++ | NA | 1.34 | 0.65 | |
| Presenteeism loss | ||||
| Per capita presenteeism days | Mean (SD) | 16 (34) | 16 (34) | 8 (27) |
| Median (CI)+ | 12 (7 18) | 12 (7 18) | 3 (0 12) | |
| Ratio++ | NA | 1.00 | 0.50 | |
| Per capita presenteeism costs | Mean (SD) | 521 (1129) | 521 (1129) | 254 (917) |
| Median (CI)+ | 389 (156 602) | 389 (156 602) | 122 (0 419) | |
| Ratio++ | NA | 1.00 | 0.49 |
SD = standard deviation, NA = not applicable, + CI =10th and 90th percentile confidence interval around median, Ratio++ = ratio of disruption correction mean (or friction correction mean) to compensation mean. *Friction correction differs from compensation and disruption correction mean p < .0001.
