Background
Mailed fecal immunochemical testing (FIT) can increase colorectal cancer (CRC) screening rates, including for vulnerable patients, but its cost-effectiveness is unclear.
Objective
We sought to examine the effectiveness and cost-effectiveness of the initial cycle of our mailed FIT program from November 2017 to July 2019 in a federally qualified health center (FQHC) system in Central Texas.
Design
Single group intervention and economic analysis
Participants
Eligible patients were those ages 50–75 who had been seen recently in a system practice and were not up to date with screening.
Intervention
The program mailing packet included an introductory letter in plain language, the FIT itself, easy to read instructions, and a postage-paid lab mailer, supplemented with written and text messaging reminders.
Main Measures
We measured effectiveness based on completion of mailed FIT and cost-effectiveness in terms of cost per person screened. Costs were measured using detailed micro-costing techniques from the perspective of a third-party payer and expressed in 2019 US dollars. Direct costs were based on material supply costs and detailed observations of labor required, valued at the wage rate.
Key Results
Of the 22,838 eligible patients who received program materials, mean age was 59.0, 51.5% were female, and 43.9% were Latino. FIT were successfully completed by 19.2% (4395/22,838) patients at an average direct cost of $5275.70 per 500-patient mailing. Assuming completed tests from the mailed intervention represent incremental screening, the direct cost per patient screened, compared with no intervention, was $54.83. Incorporating start-up and indirect costs increases total costs to $7014.45 and cost per patient screened to $72.90. Alternately, assuming 2.5% and 5% screening without the intervention increased the direct (total) cost per patient screened to $60.03 ($80.80) and $67.05 ($91.47), respectively.
Conclusions
Mailed FIT is an effective and cost-effective population health strategy for CRC screening in vulnerable patients.
