Trends and disparities in access to minimally invasive distal pancreatectomy (midp): an eight-year analysis from the national cancer database.

Abstract

Laparoscopic and robotic approaches to distal pancreatectomy are becoming the standard of care. The aim of our study was to evaluate the trends of utilization and disparities in access to minimally invasive approaches in distal pancreatectomy. We queried the National Cancer Database (NCDB) and analyzed all the patients who underwent distal pancreatectomy from 2010 to 2017. Patients were divided into groups of those with open distal pancreatectomy (ODP) and those with laparoscopic or robotic distal pancreatectomy (MIDP = minimally invasive distal pancreatectomy). Our outcome measures were trends of MIDP and disparities in access to MIDP. Cochran Armitage trend analysis and multivariate regression analysis were used to evaluate outcomes. A total of 13,537 patients with distal pancreatectomy were identified in the NCDB from 2010 to 2017. 7548 (55.8%) underwent ODP, while 5989 (44.2%) underwent MIDP. The MIDP rates increased from 25% in 2010 to 52% in 2017 (p < 0.01). On regression analysis, when controlled for age, gender, diagnosis, tumor size, grade, staging, and chemoradiotherapy, African American patients were 30% less likely to undergo MIDP than White (OR 0.7, 95% CI [0.5-0.8], p < 0.01). Similarly, Hispanic patients were 25% less likely to undergo MIDP than non-Hispanic patients OR 0.75, 95% CI [0.6-0.9], p = 0.02). Compared to Medicare/private insured patients, uninsured patients were 50% less likely to undergo MIDP (OR 0.5, 95% CI [0.4-0.7], p < 0.01). Based on the medium household income, compared to patients in the fourth quartile, patients in the third quartile OR 0.9, 95% CI [0.3-0.9], p = 0.03). Second OR 0.8, 95%CI [0.5-0.9], p < 0.01), first quartile OR 0.7, 95% CI [0.5-0.8], p < 0.01) were less likely to undergo MIPD as well. Utilization of MIDP has increased from one in every four patients in 2010 to every other patient in 2017. However, African Americans, Hispanics, the uninsured, and those from low-income quartiles are less likely to undergo MIDP. Efforts should be made to ensure access to minimally invasive approches are available to minorities.
