International standards of care in thoracic oncology: A narrative review of clinical quality indicators

Abstract

Unwarranted variations in lung cancer care are widely described. Clinical Quality Indicators (CQIs) enable the systematic identification and alleviation of variations in care and other evidence-practice gaps. The aim of this review was to describe and evaluate lung cancer CQIs utilised internationally, in order to provide a substrate for the development of Australasian lung cancer CQIs and future quality improvement initiatives. A literature search was performed to identify relevant publications; references were excluded if they did not explicitly define original lung cancer-specific quality indicators, or were review or opinion articles. Ultimately, 48 publications containing 661 individual CQIs were evaluated. Although almost all references were published in the last decade, CQIs did not always reflect contemporary standards of care. For example, there were just sixteen CQIs regarding biomarker profiling, eleven CQIs regarding multidisciplinary team review, and three clinical trial enrolment CQIs. Of 307 lung cancer treatment CQIs, almost half (137) pertain to surgical resection; a treatment option available to a minority of lung cancer patients. Consumer engagement during indicator development was uncommon. In conclusion, whilst CQIs are widely measured and reported, they are not always consistent with evidence-based practice, nor do they reliably support the holistic evaluation of the lung cancer care continuum. Moving forward, Australia and New Zealand must adopt a unified, evidence-based and patient-centred approach to drive meaningful improvements in practice.
