Fecal Microbiota Transplantation in Pouchitis: Clinical, Endoscopic, Histologic, and Microbiota Results from a Pilot Study.

AIMS: This pilot study assessed the efficacy, safety, and microbiome dynamics of fecal microbiota transplantation (FMT) for patients with chronic pouchitis. METHODS: A prospective open-label pilot study was performed at an academic center among pouchitis patients undergoing FMT. Patients received a minimum of a single FMT by pouchoscopy from healthy, screened donors. The primary outcome was clinical improvement in pouchitis assessed by patient survey at week 4. Secondary outcomes included decrease in total Pouchitis Disease Activity Index (PDAI) Score ≥ 3 at week 4, bowel movement frequency, ESR, CRP, fecal calprotectin, abdominal pain, and PDAI subscores including endoscopic and histologic changes. Stool samples were collected at baseline and 4 weeks post-FMT to assess bacterial microbiota using V4 16S rRNA sequencing. RESULTS: Nineteen patients were enrolled; however, 1 patient was lost to follow-up. No patients had a major adverse event or escalation of therapy related to FMT. Total PDAI scores, endoscopic scores, and histologic scores did not decrease significantly post-FMT. However, there was a statistically significant improvement in bowel movement (BM) frequency (9.25-7.25 BM/day, p = 0.03) and trend for improvement in abdominal pain to improve post-FMT (p = 0.05). Bacterial microbiota profiling revealed no distinct community-level changes post-FMT, though a small number of specific bacterial taxa significantly differed in relative abundance. CONCLUSIONS: A single FMT has a tolerable short-term safety profile and may be associated with a decrease in bowel movements in patients with chronic pouchitis; however, no robust endoscopic or histologic changes were observed.

Gastroenterologist and primary care perspectives on a post-endoscopy discharge policy: impact on clinic wait times, provider satisfaction and provider workload.

BACKGROUND: To reduce unnecessary ambulatory gastroenterology (GI) visits and increase access to GI care, San Francisco Health Network gastroenterologists and primary care providers implemented guidelines in 2013 that discharged certain patients back to primary care after endoscopy with formal written recommendations. This study assesses the longer-term impact of this policy on GI clinic access, workflow, and provider satisfaction. METHODS: An email-based survey assessed gastroenterologist and primary care provider (PCP) opinions about the discharge process. Administrative data and chart review were used to assess clinic access, intervention fidelity, and re-referral rates. RESULTS: 102/299 (34%) of PCPs and 5/7 (71%) of gastroenterologists responded to the survey. 74% of PCPs and 100% of gastroenterologists were satisfied or very satisfied with the discharge process. 80% of gastroenterologists believed the discharge process decreased their workload, while 53.5% of primary care providers believed it increased their workload. 6.7% of patients discharged to primary care in 2013 had re-referrals to GI. Wait time for the third-next-available new outpatient GI clinic appointment had previously decreased from 158 days (2012, pre-intervention) to 74 days (2013, post-intervention). In 2015, wait time was 19 days (p < 0.001 for 2012 vs. 2015). CONCLUSIONS: Primary care providers and gastroenterologists are satisfied with an intervention to discharge patients from gastroenterology to primary care after certain endoscopic procedures, although this conclusion is limited by a relatively low PCP survey response rate. Discharging appropriate patients using consensus criteria from the gastroenterology clinic was instrumental in sustainably reducing clinic wait times with low re-referral rates.
