Evaluation of any health service initiative is critical to providing robust evidence for practice in healthcare (Proctor et al., 2011). The aim of a GEDI service evaluation is to compare outcomes from before service commenced to after service is in place. An evaluation may include and is not limited to:
- Quantitative analysis of disposition, length of stay in the ED, length of stay if admitted, representations up to 28 days after discharge and same cause mortality
- Health economic cost-effectiveness analysis
- Qualitative structure and process analysis to determine service users and staff issues with the health service.
