Quantitative Versus Qualitative Fecal Immunochemical Tests (FIT) to Prioritize Urgency of Colonoscopy Referral

October 25, 2017 updated by: University of Malaya

Evaluating the Effectiveness of Screening Strategies Using Quantitative Versus Qualitative Fecal Immunochemical Test (FIT) to Prioritize Urgency of Colonoscopy Referral - a Randomized Controlled Trial Protocol

The main aim of this study is to determine whether there is a difference in time to diagnosis of advanced colorectal neoplasms using quantitative Fecal Immunochemical Tests (FIT) to prioritize referral for colonoscopy (intervention) compared to usual care (qualitative FIT and appointment-based referral).

Design Details

  • Primary Purpose: Screening
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Qualitative fecal immunochemical test

Stool samples will be tested with the qualitative fecal immunochemical test (qFIT), and will be stratified for colonoscopy as follows:

>200 ng/dL - colonoscopy with one month 100-200 ng/dL - colonoscopy as per waiting list <100 ng/dL - no colonoscopy

Cost analysis, anxiety scores and patient satisfaction scores will be calculated for all patients.

This test measures the amount of blood within the submitted stool specimen
Patients with positive tests will be subjected to colonoscopy to determine presence or absence of advanced colorectal neoplasms.
Data on direct and indirect costs to patient and institution will be collected at each patient visit related to screening.
Hospital Anxiety and Depression Scale (HADS) questionnaire
A 5-point patient satisfaction score will be documented at each patient visit related to screening.
Other: Quantitative fecal immunochemical test

Stool samples will be tested with the quantitative fecal immunochemical test (FIT), and will be scheduled for colonoscopy as follows:

Positive - colonoscopy as per waiting list Negative - no colonoscopy

Cost analysis, anxiety scores and patient satisfaction scores will be calculated for all patients.

Patients with positive tests will be subjected to colonoscopy to determine presence or absence of advanced colorectal neoplasms.
Data on direct and indirect costs to patient and institution will be collected at each patient visit related to screening.
Hospital Anxiety and Depression Scale (HADS) questionnaire
A 5-point patient satisfaction score will be documented at each patient visit related to screening.
This test detects presence or absence of blood within a submitted stool specimen.
