Risk and Outcomes of Clostridium difficile Infection With Chronic Pancreatitis



Supplemental digital content is available in the text. Objectives Chronic pancreatitis (CP) is associated with high rates of recurrent hospitalizations, which predisposes to Clostridium difficile infection (CDI). We investigate the burden of CDI in CP. Methods We identified records of patients with CP from the Nationwide Inpatient Sample (NIS) 2012–2014 and estimated the impact of CDI on their outcomes. We calculated the adjusted odds ratio (AOR) of CP on having CDI (NIS 2014). From NIS 2007–2014, we plotted the trends of CDI and its interaction with CP. Results From 2012 to 2014, 886 (2.72%) of the 32,614 CP patients had concomitant CDI, which was associated with poorer outcomes: acute kidney injury (AOR, 2.57 [95% confidence interval {CI}, 2.11–3.13]), length of stay (13.3 vs 7.4 days), and charges (US $127,496 vs US $72,767), but not mortality (AOR, 0.93 [95% CI, 0.28–3.05]). In 2014, CP was associated with an increased risk of CDI (crude odds ratio, 2.10 [95% CI, 1.95–2.26]), which persisted after multivariate adjustment (AOR, 2.03 [95% CI, 1.87–2.19]). From 2007 to 2014, the annual prevalence of CDI was 106.4 cases per 10,000 hospitalizations, increasing from 2007 (95.5/10,000) to 2014 (118.4/10,000), with a 3.7 times higher annual rate of increase among CP versus no-CP patients (13.4/10,000 vs 3.7/10,000 population/year). Conclusions Chronic pancreatitis patients have high burden of CDI and may benefit from CDI prophylaxis.
