Over the past couple of decades, chlamydia screening has been discussed, started, changed, discussed, evaluated, disagreed with, and discussed again.
One thing I think has been missing is large scale Randomised Controlled Trials performed early on, and used to make cost-effective decisions.
Instead decisions have been made on trials that have now been decided as flawed, and last year the National Audit Office - Chlamydia testing ‘wasting money’ – concluded that millions have been wasted.
And this week the BMJ reports that screening for chlamydia with a single test doesn’t prevent pelvic inflammatory disease. – Randomised controlled trial of screening for Chlamydia trachomatis to prevent pelvic inflammatory disease: the POPI (prevention of pelvic infection) trial
Obtaining more information will be nearly impossible – now that screening kits in GP surgeries are endemic, any more “pure” trials – where people are either screened as part of a study, or aren’t screened as part of a study, are going to be much harder to do.
