The cost of Pancreatoduodenectomy - An analysis of clinical determinants.

BACKGROUND: Health care spending is increasing the world over. Determining preventable or correctable factors may offer us valuable insights into developing strategies aimed at reducing costs and improving patient care. The aim of this study was to conduct an exploratory analysis of clinical factors influencing costs of Pancreatoduodenectomy (PD).

METHODS: The financial and clinical records of 173 consecutive patients who underwent PD at a tertiary care referral centre, between January 2013 and June 2015 were analysed.

RESULTS: Complications, by themselves, did not increase costs associated with PD unless they resulted in an increase in the duration of stay more than 11 days. Intraoperative blood transfusion (p-.098) and performance of an end-to-side PJ (p-.043) were independent factors significantly affecting costs. Synchronous venous resections significantly increased costs (p-.006) without affecting duration of stay. Advancing age, hypertension, neurological and respiratory disorders, preoperative endoscopic retrograde cholangiopancreatography (ERCP), performance of a feeding jejunostomy, and surgical complications eg PPH, POPF and DGE significantly increased the duration of stay sufficient enough to influence costs of PD.

CONCLUSIONS: It is not the merely the development, but severity of complications that significantly increase the cost of PD by increasing hospital stay. Strategies aimed at reducing intraoperative blood transfusion requirement as well as minimising the development of POPF can help reduce costs. Synchronous venous resections significantly increase costs independent of hospital stay. This study identified nine factors that may be included in the development of a preoperative nomogram that could be used in preoperative financial counselling of patients undergoing PD.
