This is the protocol for a systematic review which will examine how well the impacts of insurance schemes are assessed. It will assess changes with the introduction of social health insurance in:
1. the health status of patients using the health services provided.
2. out of pocket expenditure per episode of illness relative to income and by income class (catastrophic health spending).
3. the utilisation of a health service use.
The protocol provides background information and details of the methods to be used.
