No association between COVID-19 related liver injury and the course of disease: a retrospective study.

Objective: Several studies have reported on liver injury during COVID-19. However, the definition and timing of liver injury is different among the published articles. The aim of the present study is to evaluate whether COVID-19 related liver injury at the time of first presentation is associated with the course of the disease.

The appropriateness of surveillance colonoscopy intervals after polypectomy.

Background: Adherence to surveillance colonoscopy guidelines is important to prevent colorectal cancer (CRC) and unnecessary workload.

Objective: To evaluate how well Canadian gastroenterologists adhere to colonoscopy surveillance guidelines after adenoma removal or treatment for CRC.

Methods: Patients with a history of adenomas or CRC who had surveillance performed between October 2008 and October 2010 were retrospectively included.

The Global Rating Scale in clinical practice: a comprehensive quality assurance programme for endoscopy departments.

Background: The Global Rating Scale is an endoscopy quality assurance programme, successfully implemented in England. It remains uncertain whether it is applicable in another health care setting.

Aim: To assess the applicability of the Global Rating Scale as benchmark tool in an international context.

The incidence of 30-day adverse events after colonoscopy among outpatients in the Netherlands.

Objectives: Colonoscopy is the gold standard for visualization of the colon. It is generally accepted as a safe procedure and major adverse events occur at a low rate. However, few data are available on structured assessment of (minor) post-procedural adverse events.

Awareness of postpolypectomy surveillance guidelines: a nationwide survey of colonoscopists in Canada.

Introduction: Due to the increasing demand for colonoscopy, adherence to postpolypectomy surveillance guidelines is important. Suboptimal compliance can lead to unnecessary risks and ineffective use of resources.

Objective: To determine the awareness of and adherence to postpolypectomy surveillance guidelines among members of the Canadian Association of Gastroenterology (CAG).

Awareness of surveillance recommendations among patients with colorectal adenomas.

Background & Aims: The efficacy of colorectal cancer screening programs depends on the rate of attendance at surveillance colonoscopy examinations. Increasing patients' awareness about the importance of surveillance might improve attendance, but it is not clear how much they know about their follow-up recommendations. We assessed the awareness of patients with adenomas about their surveillance recommendations.

Quality evaluation of colonoscopy reporting and colonoscopy performance in daily clinical practice.

Background: Comprehensive monitoring of colonoscopy quality requires complete and accurate colonoscopy reporting.

Objective: This study aimed to assess the compliance with colonoscopy reporting and to assess the quality of colonoscopy performance.

Design: Consecutive colonoscopy reports were reviewed by hand.

Overview of the quality assurance movement in health care.

This chapter aims to describe the origin and current status of quality assurance (QA) in health care and to provide a background of similar developments in other industries, which have provided a major impetus for QA initiatives in health care. The interest in quality and safety in the health care sector has rapidly risen over the past decade. Without important lessons learnt from other industries, the interest and obtained improvements would have been far less fast.

A prospective audit of patient experiences in colonoscopy using the Global Rating Scale: a cohort of 1,187 patients.

Background: The Global Rating Scale (GRS) comprehensively evaluates the quality of an endoscopy department, providing a patient-centred framework for service improvement.

Objective: To assess patient experiences during colonoscopy and identify areas that need service improvement using the GRS.

Methods: Consecutive outpatients undergoing colonoscopy were asked to complete a pre- and postprocedure questionnaire.

Quality assurance of endoscopy in colorectal cancer screening.

This chapter explores the concept of quality assurance of colorectal cancer screening. It argues that effective quality assurance is critical to ensure that the benefits of screening outweigh the harms. The three key steps of quality assurance, definition of standards, measurement of standards and enforcement of standards, are explained.

Increased incidence of early de novo cancer in liver graft recipients treated with cyclosporine: an association with C2 monitoring and recipient age.

The goal of this study was to determine the risk factors for de novo cancer after liver transplantation (LTx). Retrospective analyses were performed in 385 LTx patients who underwent transplantation between 1986 and 2007. In total, 50 (13.

Colorectal cancer in post-liver transplant recipients.

Purpose: Several malignancies have been reported to occur more often after liver transplantation. Whether this is also true for colorectal carcinoma is controversial. Our aims were 1) to compare the observed rate of colorectal carcinoma in a post-liver transplantation cohort with incidence data from the general Dutch population, and 2) to stratify for patients with and without primary sclerosing cholangitis, because primary sclerosing cholangitis is well established as a risk factor for colorectal carcinoma.
