Closing the feedback loop: an audit of the use of imiquimod for the treatment of genital warts.
A retrospective case-note audit of 74 patients with 81 treatment episodes of anogenital warts with imiquimod from April 1999 until July 2000 was performed. The majority of patients had failed to clear their warts with other treatments, had recurrences after other treatments, or had other medical problems complicating their genital wart treatment. The overall clinically confirmed complete clearance rate was 33%. This is lower than other published data, but may be so because it includes patients with immunosuppression and difficult-to-treat warts. The complete clearance rate in immunocompetent patients was 37%. In addition, in this audit of clinical practice 17% of the patients did not return for full response to be assessed. The complete clearance rate in those who were able to tolerate treatment and who returned for follow-up was 45%. Based on the results of the audit we have extended the indications for the use of imiquimod in the clinic treatment guidelines. Patients are now offered imiquimod if six or more episodes of other treatments fail to give a good response. Earlier treatment with imiquimod is also offered to those patients with recurrent anogenital warts, and it is recommended as a first-line therapy for patients with multiple keratinized warts.
