Background
Preoperative overnight fasting of patients (no oral intake from midnight until the time of surgery) is a potentially harmful practice; nevertheless, it remains common. Prolonged preoperative fasting is frequent, at times up to 24 hours of fluid and nutrition deprivation. International guidelines recommend reduced fasting time to improve patient outcomes, but this evidence is not well implemented. This study investigated clinician perspectives on two interventions designed to reduce preoperative fasting.
Methods
The qualitative study was informed by the Consolidated Framework for Implementation Research (CFIR). Semi-structured interviews were conducted virtually or in person, with a purposive sample of perioperative health professionals. Thematic analysis revealed codes, some of which were specific to the two reduced fasting interventions (SipTilSend and oral carbohydrate loading), organised according to the CFIR constructs.
Results and Conclusions
Twenty-one multidisciplinary clinicians were interviewed. Within the CFIR domains, adaptability enabled the tailoring of interventions to clinical contexts, while governance and policy updates supported adoption (Innovation). Progressive anaesthesia team leaders and leadership engagement drove change (Individuals). However, outdated policies and disincentives hindered progress (Outer Setting). Barriers included a lack of knowledge, while knowledge dissemination and clinician commitment to patient safety facilitated uptake (Inner setting). Champions among anaesthesia leaders and perioperative interdisciplinary collaboration played key roles in implementation success (Process).
