Discussion
Through a proactive, population-based CRC screening program centered on mailed FIT kits outside of the traditional patient visit, the VACHS increased the use of FIT and rates of CRC screening. The numbers of FIT kits ordered and completed substantially increased in the 3 months after program launch.
Compared to mailed FIT programs described in the literature that rely on centralized processes in that a separate team operates the mailed FIT program for the entire organization, this program used existing PACT infrastructure and staff.10,11 This strategy allowed VACHS to design and implement the program in several months. Not needing to hire new staff or create a central team for the sole purpose of implementing the program allowed us to save on any organizational funding and efforts that would have accompanied the additional staff. The program described in this article may be more attainable for primary care practices or smaller health systems that do not have the capacity for the creation of a centralized process.
Limitations
Although the total number of FIT completions substantially increased during the program, the rate of FIT completion during the mailed FIT program was lower than the rate of completion prior to program launch. This decreased rate of FIT kit completion may be related to separation from a patient visit and potential loss of real-time education with a clinician. The program’s decentralized design increased the existing workload for primary care staff, and as a result, consideration must be given to local staffing levels. Additionally, the report of eligible patients depended on diagnosis codes and may have captured patients with higher-than-average risk of CRC, such as patients with prior history of adenomatous polyps, family history of CRC, or other medical or genetic conditions. We attempted to mitigate this by including a list of conditions that would exclude patients from FIT eligibility in the FIT letter and giving them the option to opt out.
Conclusions
CRC screening rates improved following implementation of a primary care team-centered quality improvement process to proactively identify patients appropriate for FIT and mail them FIT kits. This project highlights that population-health interventions around CRC screening via use of FIT can be successful within a primary care patient-centered medical home model, considering the increases in both CRC screening rates and increase in FIT tests ordered.
