The purpose of this study is to compare two different strategies to implement a new method to identify patients with HNPCC, which appeared cost-effective and feasible. The effectiveness, costs and feasibility of both of the implementation strategies will be assessed.

Further study details as provided by Radboud University:

Primary Outcome Measures:
  • Efficacy of inclusion of eligible CRC-patients for MSI testing by pathologists.
  • Efficacy of referral of patients who are MSI positive to a clinical geneticist by surgeons.

Secondary Outcome Measures:
  • Experiences with and acceptance of changed physician practice roles by patients and clinicians.
  • Cost efficacy of the implementation procedures.

Estimated Enrollment: 360
Study Start Date: September 2005
Estimated Study Completion Date: July 2007
Detailed Description:
The Radboud University Nijmegen Medical Centre developed a new method to identify patients with HNPCC. This method appeared cost-effective and feasible. Using this new method 70% of the HNPCC patients will be identified as compared to less than 30% when the current method is used. However, this new method does not implement itself; large gaps exists between best evidence and daily practice. This study will compare an intensive strategy, consisting of distribution of educational materials, education, feedback and reminders, with a minimal strategy, only consisting of distribution of a critical care pathway. The aim is to find the most cost-effective strategy to implement the new method to identify patients with HNPCC in the Netherlands.
