Sensitivity analysis

|---|---|---|---|
| Values | Government perspective | PDT cost only | |
| Base case | 9 | 38 | |
| Government perspective, low estimate | £1325/year | 32 | NA |
| Angiogram follow up* | £2640 (angiogram+outpatient visit every 3 months after PDT treatment ends) | 24 | 54 |
| Cost per QALY, 5 year time frame, cohort with best corrected visual acuity = 20/100 (in £000) | |||
|---|---|---|---|
| Values | Government perspective | PDT cost only | |
| *In the base case, it is assumed that an angiogram is used for follow up only during the course of treatment. This sensitivity analysis assumes PDT treated patients have an angiogram and outpatient visit every 3 months for the entire period of the model for follow up, regardless of whether or not PDT is being given. This is in addition to standard follow up being done for non-PDT treated patients. | |||
