BACKGROUND & AIMS: The fecal immunochemical test (FIT) is widely used in colorectal cancer (CRC) screening. The OC-Light FIT is 1 of 2 FITs recommended for CRC screening by the Preventive Services Task Force guidelines. However, little is known about its ability to detect CRC in large average-risk populations. METHODS: We performed a retrospective cohort study of patients (50-75 years old) in the San Francisco Health Network who were screened for CRC by OC-Light FIT from August 2010 through June 2015...

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...

BACKGROUND AND AIMS: Lower GI bleeding (LGIB) is a common cause of morbidity and mortality. Colonoscopy is indicated in all hospitalized patients with LGIB, yet the time frame for performing colonoscopy remains unclear. Prior studies of outcomes in urgent versus elective colonoscopy have yielded conflicting results and were often underpowered. Our study objective was to compare several outcomes between urgent and elective colonoscopy in patients hospitalized for LGIB. METHODS: Systematic review and meta-analysis were performed on studies that compared urgent and elective colonoscopy in patients with LGIB...

OBJECTIVES: The effectiveness of stool-based colorectal cancer (CRC) screening is contingent on colonoscopy completion in patients with an abnormal fecal immunochemical test (FIT). Understanding system and patient factors affecting follow-up of abnormal screening tests is essential to optimize care for high-risk cohorts. METHODS: This retrospective cohort study was conducted in an integrated safety-net system comprised of 11 primary-care clinics and one Gastroenterology referral unit and included patients 50-75 years, with a positive FIT between April 2012 and February 2015...

Background and aims  Precut papillotomy is widely used after failed biliary cannulation. Endoscopic ultrasound (EUS)-guided biliary access techniques are newer methods to facilitate access and therapy in failed cannulation. We evaluated the impact of EUS-guided biliary access on endoscopic retrograde cholangiopancreatography (ERCP) success and compared these techniques to precut papillotomy. Patients and methods  We retrospectively compared two ERCP cohorts. One cohort consisted of biliary ERCPs (n = 1053) attempted in patients with native papillae and surgically unaltered anatomy in whom precut papillotomy and/or EUS-guided biliary access were routinely performed immediately after failed cannulation...

Lynch syndrome (LS) is the most common cause of hereditary colorectal cancer (CRC), and national guidelines recommend screening patients with CRC for LS. However, there is a paucity of data related to Lynch syndrome in the underserved population, in which unique issues of access, cultural beliefs regarding cancer, language barriers, immigration status, and financial restraints exist. We performed a descriptive, retrospective review of a selective LS screening protocol at an urban safety net hospital between 2009 and 2014 with the aim of describing the detected prevalence of LS as well as reporting the high quality and suboptimal screening rates...

BACKGROUND: Demand for endoscopic procedures scheduled with anesthesia is increasing and no-show to appointments carries significant patient health and financial impact, yet little is known about predictors of no-show. METHODS: We performed a 16-month retrospective observational cohort study of patients scheduled for outpatient endoscopy with anesthesia at a county hospital serving the safety-net healthcare system of San Francisco. Multivariate logistic regression analysis was performed to evaluate associations between attendance and predictors of no-show...

Efficiency is defined as the use of resources in such a way as to maximize the production of goods and services. Improving efficiency has been the focus of management in many industries; however, it has not been until recently that incorporating efficiency models into healthcare has occurred. In particular, the study and development of improvement projects aimed at enhancing efficiency in GI have been growing rapidly in recent years. This focus on improving efficiency in GI has been spurred by the dramatic rise in the demand for endoscopic procedures as well as the rising number of insured patients requiring GI care coupled at the same time with limited resources in terms of staffing and space in endoscopy centers...

Colorectal cancer is common worldwide, and the elderly are disproportionately affected. Increasing age is a risk factor for the development of precancerous adenomas and colorectal cancer, thus raising the issue of screening and surveillance in older patients. Elderly patients are a diverse and heteroge-neous group, and special considerations such as comorbid medical conditions, functional status and cognitive ability play a role in deciding on the utility of screening and sur-veillance. Colorectal cancer screening can be beneficial to patients, but at certain ages and under some circumstances the harm of screening outweighs the benefits...

OBJECTIVES: Access to specialty care among safety net patients in the United States is inadequate. Discharging appropriate patients to routine primary care follow-up may improve specialty care access. We sought to identify, by consensus, patients who could safely be discharged from a gastroenterology (GI) clinic, and to evaluate the impact of the discharges on GI clinic work flow. STUDY DESIGN: Pre- and post intervention. METHODS: We developed and implemented a modified Delphi process...

Colorectal cancer (CRC) disproportionately affects the elderly. Older age is a strong risk factor for both the development of precancerous adenomas and CRC, thus raising the issue of screening and surveillance in older patients. However, screening and surveillance decisions in the elderly can be complex and challenging. Elderly patients are a diverse and heterogeneous group and special considerations such as co-morbid medical conditions, functional status, and cognitive ability play a role in one's decisions regarding the utility of screening and surveillance...
