National Improvement of Waiting Times: First Results From the Dutch Head and Neck Audit

Abstract

AbstractObjectiveTimely treatment initiation in head and neck cancer (HNC) care is of great importance regarding survival, oncological, functional, and psychological outcomes. Therefore, waiting times are assessed in the Dutch Head and Neck Audit (DHNA). This audit aims to assess and improve the quality of care through feedback and benchmarking. For this study, we examined how waiting times evolved since the start of the DHNA.Study DesignProspective cohort study.SettingNational multicentre study.MethodsThe DHNA was established in 2014 and reached national coverage of all patients treated for primary HNC in 2019. DHNA data on curative patients from 2015 to 2021 was extracted on national (benchmark) and hospital level. We determined 3 measures for waiting time: (1) the care pathway interval (CPI, first visit to start treatment), (2) the time to treatment interval (TTI, biopsy to start treatment), and (3) CPI‐/TTI‐indicators (percentage of patients starting treatment ≤30 days). The Dutch national quality norm for the CPI‐indicator is 80%.ResultsThe benchmark median CPI and TTI improved between 2015 and 2021 from 37 to 26 days and 37 to 33 days, respectively. Correspondingly, the CPI‐ and TTI‐indicators, respectively, increased from 39% to 64% and 35% to 40% in 2015 to 2021. Outcomes for all hospitals improved and dispersion between hospitals declined. Four hospitals exceeded the 80% quality norm in 2021.ConclusionWaiting times improved gradually over time, with 4 hospitals exceeding the quality standard in 2021. On the hospital‐level, process improvement plans have been initiated. Systematic registration, auditing, and feedback of data support the improvement of quality of care.
