Objective: This study examined knowledge and practice of breakthrough cancer pain (BTcP) management among general practitioners (GPs) providing palliative care in Shanghai.
Design: Cross-sectional study using a self-administered questionnaire.
Setting and participants: A total of 393 GPs providing palliative care in 32 community health service centres in Shanghai were recruited by stratified cluster random sampling between 1 May and 30 June 2022.
Outcome measures: Knowledge and practice concerning BTcP management.
Results: A total of 375 questionnaires were collected and declared valid. The median knowledge score was 11 out of 21 points. Only 36.3% (n=136) of the participating GPs scored 11 points or more, which was categorised as good knowledge. Only 24.8% (n=93) of the GPs used Davies' adapted diagnostic algorithm as the gold standard for diagnosis. All of the GPs assessed the intensity of BTcP; however, less than a quarter of the GPs evaluated the relationship between background pain and BTcP (22.1%, n=83), the impact of BTcP on activities of daily living (24.0%, n=90), the impact of BTcP on social relationships (14.4%, n=54) and the impact of BTcP on mood (10.1%, n=38). 56.5% (n=212) of the GPs reported that they used pain tools in the assessment of BTcP. All of the GPs prescribed immediate-release morphine as rescue medication for relieving BTcP; however, 60.5% (n=227) prescribed the dose based on their personal experiences, irrespective of the basal opioid dose, and 57.3% (n=215) did not conduct dose titration after providing the initial dose. No GPs reported that they ever administered interventional treatment to their patients.
Conclusions: Insufficient knowledge and inappropriate behaviours in BTcP diagnosis, assessment and treatment were identified. There is an urgent need to improve BTcP management among GPs providing palliative care in Shanghai.
