Sensitivity analyses for a screening programme for women aged 15–40 years; variations in the probability estimates for sequelae, discount rate, and test characteristics (in US$)
| Parameter | Range (%) | Cost per MOA (min) | Cost per MOA (max) | Change (%) |
|---|---|---|---|---|
| PID = pelvic inflammatory disease, EP = ectopic pregnancy, TFI = tubal factor infertility, CPP = chronic pelvic pain, MOA = major outcome averted (either an episode of PID, CPP, EP, TFI, or neonatal pneumonia), min = minimum probabilities, max = maximum probabilities. | ||||
| *Estimate and resulting cost per MOA in the baseline analysis. | ||||
| Risk PID | 5–25 | 28 300 | 6 380 | −78 |
| Risk EP | 4–16 | 16 500 | 14 600 | −12 |
| Risk TFI | 4–16 | 16 100 | 15 300 | −5 |
| Risk CPP | 10–20 | 16 400 | 15 300 | −7 |
| Preventable PID | 25–75 | 28 300 | 10 400 | −63 |
| Sensitivity of the test | 85–90 | 15 800* | 15 800 | 0 |
| Specificity of the test | 99–99.9 | 15 800* | 9 540 | −40 |
| Discount rate | 0–7 | 15 800 | 15 900 | +1 |
