Implementation of prospective, surgeon-driven, risk-based pathway for pancreatoduodenectomy results in improved clinical outcomes and first year cost savings of $1 million.

ABSTRACT

BACKGROUND: Morbidity and costs after pancreatoduodenectomy remain increased, driven by postoperative pancreatic fistula (POPF). A risk-based pathway for pancreatoduodenectomy (RBP-PD) was implemented and the clinical and cost outcomes compared with that of our historic practice. METHODS: Prospective clinical and cost outcomes for our RBP-PD cohort treated from September 2014 to September 2015 were compared with a previously published cohort of pancreatoduodenectomies from January 2007 to February 2014. RESULTS: A total of 128 RBP-PD cases were compared with 808 historic controls. Apart from less blood loss, there were no significant clinical differences between the 2 groups. Overall POPF rate did not change. Average duration of stay decreased to 10 days from 12 (P < .001) despite similar readmission rates. Postsurgical interventional radiology procedures decreased to 18.0% from 26.4% (P = .048). Utilization of and duration of stay in monitored care decreased to 23.4% from 35.6% (P < .01) and to 1 day from 3 (P < .01). On multivariable analysis RBP-PD was independently associated with decreased odds of higher postoperative pancreatic fistula grade, monitored care, and prolonged duration of stay. Inpatient cost of care decreased $6,387 per patient (-11.1%, P = .016), and total 30-day costs decreased $8,565 per patient (-13.7%, P = .01), representing a total 30-day cost savings of $1.1 million. CONCLUSION: RBP-PD significantly improved patient outcomes, decreased costs of care, and likely has applicability for surgical care beyond pancreatoduodenectomy.
