Table 5 Cost-effectiveness results (after deterministic sensitivity analyses) comparing ERS with usual care
Parameters/scenarios | How data was adjusted for in the model | Incremental cost per person | Incremental effect per person (QALY) | ICER |
|---|---|---|---|---|
Base case analysis | - | £170 | 0.008 | £20,876 |
Parameters | ||||
Intervention costs to participants | Costs of intervention was varied from £222 to £342 (including costs to providers and participants) | £290 | 0.008 | £35,652 |
Less intensive ERS | Costs of intervention was varied from £222 to £110 | £58 | 0.008 | £7,085 |
Effectiveness of ERS (based on lower limit of 95% CI) | Probability of becoming active after exposure to ERS was varied from 0.336 to 0.294 | £226 | -0.001 | Dominated* |
Effectiveness of ERS (based upper limit of 95% CI) | Probability of becoming active after exposure to ERS was varied from 0.336 to 0.371 | £122 | 0.015 | £7,947 |
Scenarios | ||||
