Lessons learned from the Dutch Institute for Clinical Auditing: the Dutch model for quality assurance in lung cancer treatment
Abstract
Background: Quality registries play an important role in the professional quality system for cancer treatment in The Netherlands. This article provides insight into the Dutch Lung Cancer Audit (DLCA); its core principles, initiation and development, first results and what lessons can be learned from the Dutch experience.
Methods: Cornerstones of the DLCA are discussed in detail, including: audit aims; the leading role for clinicians; web-based registration and feedback; data handling; multidisciplinary evaluation of quality indicators; close collaborations with all stakeholders in healthcare and transparency of results.
Results: In 2012 the first Dutch lung cancer specific sub-registry, focusing on surgical treatment was started. Since 2016 all major treating specialisms (lung oncologists, radiation-oncologists, general- and cardiothoracic surgeons—represented in the DLCA-L, -R and -S sub-registries respectively) have joined. Over time, the number of participating hospitals and included patients has increased. In 2016, the numbers of included patients with a non-small cell lung cancer (NSCLC) were 3,502 (DLCA-L), 2,427 (DLCA-R) and 1,979 (DLCA-S). Between sub-registries mean age varied from 66 to 70 years, occurrence of Eastern Cooperative Oncology Group (ECOG) performance score 2+ varied from 3.3% to 20.8% and occurrence of clinical stage I–II from 27.6% to 81.3%. Of all patients receiving chemoradiotherapy 64.2% was delivered concurrently. Of the surgical procedures 71.2% was started with a minimally invasive technique, with a conversion rate of 18.7%. In 2016 there were 17 publicly available quality indicators—consisting of structure, process and outcome indicators- calculated from the DLCA.
Conclusions: the DLCA is a unique registry to evaluate the quality of multidisciplinary lung cancer care. It is accepted and implemented on a nationwide level, enabling participating healthcare providers to get insight in their performance, and providing other stakeholders with a transparent evaluation of this performance, all aiming for continuous healthcare improvement.
