| Lt 25 | 25-29.9 | 30-34.9 | 35-39.9 | 45-49.9 | 50-54.9 | |||
| No peristomal skin irritation | 14.7 | 16.8 | 17.4 | 18.3 | 19.3 | 19.9 | 22.0 | 25.1 |
| Mild to moderate peristomal skin irritation | 15.1 | 16.6 | 17.4 | 18.2 | 18.6 | 19.5 | 21.1 | 24.3 |
| Severe peristomal skin irritation | 14.7 | 15.8 | 17.3 | 17.7 | 18.2 | 18.5 | 21.1 | 23.8 |
aQuality-adjusted life-days are based on health utilities adjusted for age, time from surgery, gender, and general health. A statistically significant difference exists between peristomal skin levels, 1 vs 2, 1 vs 3: P < .0001, 2 vs 3: P = .0014. The linear decrease in health utility values by social function, for each level of peristomal skin condition, was found to be statistically significant; P < .0001.
