Case sheets are very important instruments for improving health care quality in hospitals. Despite their importance, they are very seldom used and filled in the right way. The study is based on an attempt to optimise case sheets editing; it implies multiple steps: 1. Project development; implementation of a pattern for assessing markers (thoroughness, clearness, reliability and record tracking); 2. Delivery of personal research protocols; 3. Early analysis, assessment of results; detection of severity; 4. Correctional interventions; 5. Secondary analysis; assessment of interventions. Although most indicators have shown an improvement, outcomes remain unsatisfactory, given the extent of shortfalls before intervention.
