Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
General practitioners will be provided with a multifaceted intervention to support increased chlamydia testing in general practice. The intervention includes computer alerts, incentive payments, educational package, register to recall patients for follow up tests and quarterly feedback on chlamydia testing performance. The trial will be of up to 4 years duration.

Outcomes
Primary outcome [1] 258197 0
Chlamydia prevalence. A consecutive sample of men and women aged 16 to 29 years will be recruited prior to randomisation in each clinic and again at the conclusion of the trial. Men will be asked to provide a urine specimen and women a urine or self collected vaginal swab for chlamydia testing.
Timepoint [1] 258197 0
Measured at baseline and 4 years later at the conclusion of trial.
Secondary outcome [1] 263838 0
Incidence of pelvic inflammatory disease (PID). Diagnoses of PID will be extracted from each clinic's medical records software to determine the annual PID incidence and the cumulative incidence of PID at the conclusion of the trial 4 years later.
Timepoint [1] 263838 0
Measured throughout intervention period - annual PID incidence will be measured and a cumulative incidence measured at the conclusion of the trial after 4 years.
Secondary outcome [2] 263839 0
Chlamydia testing rates.

Chlamydia testing data will be extracted from the clinic medical records software and from the clinic pathology provider. Annual chlamydia testing rates will be calculated using the number of tests as the numerator and total number of patients seen at each clinic during the time frame as the denominator.
Timepoint [2] 263839 0
Calculated annually for 4 years.
Secondary outcome [3] 263840 0
An annual chlamydia retesting rate will be calculated for each clinic will be calculated for the 12 month period prior to commencement of the trial and then for each year of the trial till the end of the trial at 4 years.
Timepoint [3] 263840 0
An annual chlamydia retesting rate will be calculated for each clinic will be calculated for the 12 month period prior to commencement of the trial and then for each year of the trial till the end of the trial at 4 years.

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Postcodes with a population of between 5000 to 30,000 16 to 29 year old adults will be selected on the basis of convenience. All GP clinics within each postcode will be invited to participate. GPs and practice managers will be sent a postcode informing them to expect further information about the study, this will be follow up by a newsletter about the study and then a phone call to arrange a face to face meeting about the study. Once enrolled and the baseline chlamydia prevalence survey is complete, all postcodes will be randomised to either intervention or control group. Allocation will involve contacting the holder of the allocation schedule who will be “off-site” or at central administration siteClinics will be informed via phone call and then via mail of their group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Postcodes (clusters) will be randomised to the trial intervention or control strategies using a minimisation approach. This will maximise the balance across several baseline variables. These variables will include:
* Estimated baseline chlamydia prevalence in each postcode;
* Estimated overall baseline testing rate in each postcode;
* Rural town, suburban and metropolitan geographical areas;
* Estimated percentage of population aged <30 years.

Geographical areas will be randomised at UNiversity of New South Wales as soon as data on all these variables, and specifically the estimated baseline chlamydia prevalence and testing rates, are available. This means that all areas do not have to be randomised at the same time, and the study does not need to wait until baseline chlamydia prevalence and testing rates are available for all areas. The randomised intervention can then commence in areas immediately, while other areas are performing baseline chlamydia surveys.
The randomisation sequence will be held by the statistician at UNiversity of New South Wales.
