Cytoreductive surgery for ovarian cancer: quality assessment.

Surgery is the cornerstone of treatment of ovarian cancer. Given the importance of achieving no or minimal macroscopic residual disease at primary surgery, performing an assessment of the quality of ovarian cancer surgery is crucial. Assessing the quality of care and surgical outcome allows us to establish baseline information, set standards of care and clear priorities, enable benchmarking against peers, and sustain quality improvement. We know that suboptimal care exists and variation in outcomes results. One way to monitor variation in outcomes is through a clinical quality registry (CQR). A CQR collects a defined minimum dataset to measure performance of an individual or center against a range of clinical quality indicators and provides risk-adjusted, benchmarked data to participating institutions. CQR's are an excellent quality assurance measure as they capture all cases (an opt out system). They permit detection and analysis of unwarranted variations in care. This can provide indications of a systems or process problem, thereby motivating health care providers to improve services and care. Several groups have either developed quality indicators for advanced ovarian cancer surgery (The Scottish Cancer Taskforce and the European Society of Gynecological Oncology) or are in the process of doing so (Australian Society of Gynaecological Oncologists). Indicators should be evidence-based and determined by extensive discussion with experts and stakeholders to ensure appropriateness and buy-in. The Scottish Cancer Taskforce and European Society of Gynecological Oncology have set targets for their quality performance measures, which should provide a quantitative framework for improving care in the surgical management of ovarian cancer.
