Summary
Patient navigation significantly increased follow-up colonoscopy completion rates for individuals with abnormal stool tests. This intervention proved effective in improving adherence to recommended colorectal cancer screening protocols.
Area of Science:
- Public Health
- Preventive Medicine
- Gastroenterology
Background:
- Patient navigation is a recommended practice for improving health outcomes.
- Its effectiveness in increasing colonoscopy completion after abnormal stool tests is not well-established.
Purpose of the Study:
- To evaluate if patient navigation enhances follow-up colonoscopy completion.
- To assess colonoscopy completion rates at one year post-abnormal stool test.
Main Methods:
- A randomized controlled trial involving 967 participants aged 50-75 with abnormal fecal tests.
- Intervention: Telephone-based patient navigation by bilingual staff.
- Comparison: Usual care.
Main Results:
- Colonoscopy completion was higher in the patient navigation group (55.1%) versus usual care (42.1%).
- The risk difference favored patient navigation by 13.0 percentage points (95% CI, 6.5 to 19.4).
- Intervention effectiveness was consistent across patient subgroups.
Conclusions:
- Patient navigation is an effective strategy for improving follow-up colonoscopy completion.
- Supports the integration of patient navigation into screening programs for colorectal cancer.

01:25Endoscopic Procedures II: Colonoscopy
62
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
57
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

01:25Assessment of the Rectum and Anus
166
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:23Lower GI Series: Barium Enema
215
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

01:28Endoscopic Procedures III: Video Capsule Endoscopy
86
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...
