There was a wide range of activity and chlamydial diagnoses between the 177 clinics that responded. Most (92%) clinics have nucleic acid tests for chlamydial diagnosis. Different practitioners largely share roles in providing advice to patients about partner notification, treatment adherence, safer sex advice and abstinence. Most (97%) clinics have information leaflets about chlamydia, although about 30% of clinics lack leaflets containing information about antibiotics and hormonal contraception. About two-third clinics follow the National Guideline recommended interval for providing a test of cure where this is indicated. Only 18% of clinics routinely ask patients to reattend, with 40% having a policy of no routine follow-up and 62% using telephone or text follow-up. These categories were not mutually exclusive. Most (86%) of the 146 English clinics had a local Chlamydia Screening Programme coordinator for their Primary Care Trust area, although cooperation varies, with cooperation over treatment of 70% and Programme policy of 62%.
