['Rationing of health care is universal in systems free at the point of delivery. United Kingdom National Health Service (NHS) policy is for treatment on the basis of "clinical need." Surgeons routinely prioritize elective cases, and structured assessments of symptom severity have been suggested as a rational method of prioritization. We hypothesized that patient psychological factors would play an important role in prioritization as currently practiced.', "Two hundred thirty participants were recruited from a potential pool of 259 eligible referrals to an orthopaedic department for assessment of lower limb arthroplasty. Participants were assessed at time of referral and followed for 2.5 years. Associations were estimated between participant's psychological distress, illness perceptions, and the outcome of surgical prioritization.", "One hundred forty-one participants were listed for arthroplasty; 62 (44%) of these were considered urgent cases. Pain was the only univariate predictor of this outcome. Patient's psychological distress and illness perceptions were not associated with being classified as urgent even after adjusting for clinical and demographic status. In a multivariate model, only older age showed an independent effect (OR 2.75, 95% CI 1.14, 6.66) of increasing the chances of being considered urgent. Urgent cases had a 3-month-shorter inpatient wait among the 108 participants operated on during the study."] Do patient psychological characteristics have minimal influence on surgical prioritization?
