Risk taking propensity: Nurse, surgeon and patient preferences for diverting ileostomy

AIM: The decision‐making process to defunction a pelvic colorectal anastomosis involves complex heuristics and is framed by surgeon personality factors. Risk taking propensity may be an important factor in these decisions and patient preferences have not been evaluated alongside surgeons and nurses. METHODS: A prospective cross‐sectional study involving a one‐off interview and questionnaire assessing how risk taking propensity affects nurse, surgeon and patient preferences for a temporary defunctioning ileostomy (TDI) was performed. The risk taking index (RTI) was employed to evaluate risk taking propensity and the validated prospective measures of preference instruments to evaluate preferences for stoma avoidance in several scenarios by asking the individual to consider trading or gambling years of remaining life expectancy. RESULTS: One hundred and fifty participants met the inclusion criteria, which included 30 (20.0%) surgical nurses, 20 (13.3%) colorectal surgeons and 100 (66.7%) patients. Surgeons had a significantly higher RTI (mean ± SD: 26.8 ± 6.7) than patients (mean ± SD: 20.0 ± 9.8) and nurses (mean ± SD: 23.0 ± 6.6) p = 0.002. Surgeons would consider that it would be in a patient's best interest to have a TDI at an AL rate of 15% or greater, whereas nurses and patients would do so at 28% and 25%, respectively (p = 0.007). CONCLUSION: Surgeons were shown to have a higher risk taking propensity than patients and nurses but a significantly lower threshold of AL where they would consider a TDI is in the best interest of the patient.
