Cancel that PICC line order; cholecystostomy tube and short course of antibiotics

Abstract

BackgroundCurrent guidelines do not specifically address optimal antibiotic duration following cholecystostomy. This study compares outcomes for short-course (<7 days) and long-course (≥7 days) antibiotics post-cholecystostomy. MethodsThis was a retrospective review of cholecystostomy patients (≥18 years) admitted (1/1/2007-12/31/2017) to one healthcare system. ResultsOverall, 214 patients were studied. Demographics were similar, except short-course patients had higher Charlson Comorbidity Index (p < 0.0001). There were no intergroup differences in tachycardia (22.5%[short-course] vs 23.3%[long-course]) or leukocytosis (67.1%[short-course] vs 64.4%[long-course]) at drain placement nor time to normalization for pulse, temperature or leukocytosis. There were no differences regarding Clostridium Difficile infection (5.0%[short-course] vs 1.6%[long-course]) or cholecystitis recurrence (8.8%[short-course] vs 10.9%[long-course]). No differences were observed regarding gallbladder-related unplanned readmissions (30-day:18.8%[short-course] vs 17.2%[long-course]; 90-day: 20.0%[short-course] vs 25.8%[long-course]). There were no 30- or 90-day mortality differences (overall mortality: 18.3%). ConclusionPost-cholecystostomy outcomes were comparable between short-course and long-course antibiotics, consistent with emerging literature supporting short-course antibiotics for intra-abdominal infection with source control.
