The MODEL project: a scoring system to manage demand for cataract and joint replacement surgery.

Cataract surgery and joint replacement are highly cost-effective procedures; however, their availability is inequitable and doctors lack guidance on whom to refer and treat. We investigated the feasibility of using a scoring system to assess patients' suitability for operation. Wefound acceptable correlations between the scores ofgeneral practitioners and surgeons for both procedures. Scoring systems can be used in a consistent way bygeneralpractitioners and surgeons, and can make a contribution towards matching patients' needs with available treatment capacity.
