Prediction of costs, effectiveness, and disease control of a population-based program using home sampling for diagnosis of urogenital Chlamydia trachomatis Infections.

OBJECTIVE

To estimate the incremental effects and costs of a home sampling screening approach for Chlamydia trachomatis over the current in-office screening practice in Denmark.

GOALS

To assess the effect of a new screening strategy.

STUDY DESIGN

A dynamic Monte Carlo model estimated prevalence and incidence over 10 years for a home sampling screening program and the current in-office screening. Subsequently, the incremental number of major outcomes averted (MOA) and the related direct and indirect costs were estimated.

RESULTS

Infection prevalence after 10 years was 1.0% with a home sampling program and 4.2% with the current in-office screening practice. The total costs per MOA reached 3186 US dollars during the first year of the home sampling strategy, but in year 4, the accumulated indirect costs offset the direct costs, and the program henceforth saved society costs.

CONCLUSIONS

Home sampling should be considered a relevant alternative to the current practice of in-office screening.
