To describe the health outcomes and public healthcare costs of a single screening for Chlamydia trachomatis in Australian women aged 15-34 years.
A decision analytic model was used to determine the epidemiological estimates of prevalence and costs of C. trachomatis infection and its diagnosis, treatment and sequelae.
We estimate that in any female population in Australia, with a Chlamydia prevalence rate of 5.7% or higher, a single screening examination for Chlamydia is cost saving for the public healthcare system.
We found that opportunistic screening of high-risk populations is likely to be cost saving to the public healthcare system, although there is not sufficient evidence to support periodic population screening. As our model uses conservative epidemiological and public healthcare cost estimates, the health and financial impacts of C. trachomatis used in the model may be an underestimate of the true costs of infection.
描述对15 - 34岁澳大利亚女性进行一次沙眼衣原体筛查的健康结果和公共医疗成本。
采用决策分析模型来确定沙眼衣原体感染及其诊断、治疗和后遗症的患病率及成本的流行病学估计值。
我们估计，在澳大利亚任何女性人群中，沙眼衣原体患病率达到5.7%或更高时，对沙眼衣原体进行单次筛查对公共医疗系统而言可节省成本。
我们发现，对高危人群进行机会性筛查可能会为公共医疗系统节省成本，尽管没有足够证据支持进行定期人群筛查。由于我们的模型使用了保守的流行病学和公共医疗成本估计值，模型中使用的沙眼衣原体感染对健康和财务的影响可能低估了感染的实际成本。
