Delayed blood transfusion is associated with mortality following radical cystectomy
Objectives: To examine the temporal association between blood transfusion and 90-day mortality in patients with bladder cancer treated with radical cystectomy.Methods: This represents a retrospective cohort study of patients treated with radical cystectomy within the Premier Hospital network between 2003 and 2015. Patients outcomes were stratified those who received early blood transfusion (day of surgery) vs delayed blood transfusion (postoperative day ≥1) during the index admission. Primary end point was 90-day mortality following surgery.Results: The median age of 12,056 patients identified was 70 years. A total of 7,201 (59.7%) patients received blood transfusion. Within 90 days following surgery, 57 (2.2%), 162 (5.9%) and 123 (6.7%) patients in the early, delayed and both early and delayed transfused patients died respectively. Following multivariate logistic regression to account for patient (age and Charlson Comorbidity Index [CCI]) and hospital (surgeon volume, surgical approach and academic status) factors, delayed blood transfusion was independently associated with 90-day mortality (Odds ratio [OR], 2.64; 95% Confidence Interval [CI], 1.98-3.53; p < 0.001). A sensitivity analysis defining early blood transfusion as <2 days postoperatively, increased 90-day mortality persisted in patients receiving delayed transfusion (OR, 2.20; 95% CI, 1.63-3.00; p < 0.001). Older patients (≥77 years) with the highest CCI (≥2) had a 7% absolute increase in the predicted probability of 90-day mortality if they were transfused late compared to patients transfused early.Conclusion: Patient undergoing cystectomy may benefit from expedited transfusion to prevent subsequent clinical deterioration which may lead to patient mortality. Future work is needed to elucidate the optimal timing of blood transfusion.
