Table 14:
Scenario Analysis Result, Probabilities of Switching Out of Home NB-UVB Phototherapy
| Adherence | Annual Probability of Switching out of Home NB-UVBa | ICER ($/QALY) |
|---|---|---|
| Equal adherenceb | 10% | 38,424 |
| Home NB-UVB worse adherence compared to outpatient clinic NB-UVB | 11% | 72,392 |
| 12% | 215,650 | |
| 13% | Home NB-UVB is dominated (more costly, less effective) by outpatient clinic NB-UVB |
Abbreviations: ICER, incremental cost-effectiveness ratio; NB-UVB, narrowband ultraviolet B phototherapy; QALY, quality-adjusted life year.
a
The probability of switching out of home NB-UVB phototherapy after the first year. In this scenario analysis, we assumed the probability of switching out in the first year was the same as outpatient clinic NB-UVB phototherapy, at 15%.
b
Same annual probability as that of switching out of outpatient clinic NB-UVB phototherapy.
