Search Strategy for Q1 and Q2
The following search strategy was used to search the Ovid MEDLINE database for the first and second question:

The search strategy was modified as necessary for searching the remaining databases.
Search Strategy for Q3 and Q4
The following economic evaluation databases and technology assessment resources were searched for the third and fourth question:
· NHS Economic Evaluation Database (NHS EED) – Ovid interface
· Health Economic Evaluation Database (HEED)
· Health Technology Assessment (HTA, The Cochrane Library, latest issue) – Ovid interface
The following search strategy was used to search the NHS Economic Evaluation Database for the third and fourth question:

The search strategy was adapted for other electronic databases included in our search. The MEDLINE search with this search strategy combined with a recommended search filter for economic evaluations (NHS EED) yielded too many references to process.
