Preoperative Patient Reported Mental Health is Associated with High Grade Complications after Radical Cystectomy

Abstract

Purpose: Psychological distress has been associated with an impaired immune response and poor wound healing. We hypothesized that preoperative patient reported mental health would be associated with high grade 30-day complications after radical cystectomy.

Materials and methods: We retrospectively identified patients who underwent radical cystectomy for bladder cancer who completed Short Form 12 (SF-12) surveys for self-assessment of health status less than 6 months before surgery. Median physical and mental composite scores were calculated. An expert model including known predictors of postoperative high grade complications was developed, and SF-12 physical composite score and mental composite score were added to determine their association with this end point.

Results: From January 2010 to August 2014, 472 patients underwent radical cystectomy for bladder cancer, of whom 274 (58.1%) completed preoperative SF-12 questionnaires. Responders were more likely to be white (p=0.024), have higher preoperative albumin (p=0.037), receive neoadjuvant chemotherapy (p=0.002), have pT3/T4 disease (p=0.044) and have positive soft tissue surgical margins (p=0.006). Median SF-12 physical composite score was 43.1 (IQR 33.0-51.5) and mental composite score was 48.5 (IQR 39.5-54.7) in responders. Overall 46 (16.8%) responders experienced a high grade 30-day complication. Patients with a high grade complication had a lower preoperative median SF-12 mental composite score (44.8 vs 49.8, p=0.004) but no difference in physical composite score (39.2 vs 43.8, p=0.06). SF-12 mental composite score was also a significant predictive variable when added to our expert model (p=0.01).

Conclusions: Preoperative patient reported mental health was independently associated with high grade complications after radical cystectomy. Therefore, patient self-assessment of health status before surgery through validated questionnaires may provide additional information useful in predicting short-term postoperative outcomes.
