Chlamydia is a sexually transmitted infection, particularly prevalent in people under the age of 24. It is often asymptomatic and if left untreated can result in long-term complications such as pelvic inflammatory disease and infertility. The opportunistic Chlamydia screening study was conducted across Grampian, with the aim of distributing 10,000 free self-test kits within a year. Self-test kits were provided at participating sites and clients could collect a kit without the need for a consultation, complete the test, and post it to the microbiology laboratory. A simple decision analytic model was developed to estimate the costs and consequences of introducing the opportunistic Chlamydia self-test programme. The number of additional cases detected through implementation of self-testing was estimated by comparing the total number of cases detected to the number of cases that would be expected through standard case finding alone. The costs of testing kits, consultations, laboratory analysis, pharmacy fees, notification procedures, referrals, and diagnostic tests were estimated using available resource use data and unit costs.
