Quality indicators for oesophageal and gastric cancer: a population-based study in Belgium, 2004-2008

摘要

This study aimed at developing and measuring quality indicators for oesophageal cancer (OC) and gastric cancer (GC) and to support quality improvement for practitioners. Quality indicators were identified from a systematic literature search including clinical guidelines. The selection process involved experts evaluating relevance, reliability, interpretability and actionability of each indicator. Three national databases were linked: the cancer registry, the population registry and the claims database. Completeness and validity of the data were validated before being measured for 10660 patients diagnosed between 2004 and 2008. From a final set of 29 indicators, 18 were measurable using the available data. In 2008, less than 50% of patients were discussed at a multidisciplinary team meeting and less than 90% underwent a computed tomography scan 1 month after incidence date for cancer staging. Five-year relative survival was 22% for OC and 34.3% for GC. The post-operative mortality in OC patients was 4.8% (30days) and 9.9% (90days), whereas it reached 5.6 and 12.0% respectively in GC patients. This study demonstrates the feasibility to develop a set of quality indicators for gastro-oesophageal cancer. A mixed picture of the quality of care was illustrated for some relevant care processes. Nevertheless, 5-year survival is higher than reported in neighbouring countries.
