Abstract
PURPOSE To show the results of operational research techniques applied to the cataract service of a public university hospital in Brazil. METHODS. Using a heuristic approach for operational research, a study was designed to evaluate, develop solutions, and validate the implemented modifications to optimize service performance. RESULTS. Following implementation of the solutions and modifications, 24.9% more patients were examined and 39.9% more cataract surgery was performed than during a similar period prior to implementation. Solutions were provided by group discussion among service professionals and based on common sense, possibility of prompt implementation, and the use of available resources and fixed costs. CONCLUSION. The results of this study show the importance of operational research to a public cataract service wishing to improve its performance with simple and efficient solutions.
