In 1995, the Sexual Health Service in East Berkshire, UK, was formed by the integration of the clinical services of Family Planning, Genitourinary, and HIV Medicine with Sexual Health Promotion. The philosophy of the service was to provide holistic sexual health care in one visit, in one site, by one clinical team. In an outline of the practical developments and the strengths and weaknesses of such a model of service, the critical success factors in the process of developing the service were identified. These include the business case, changing the culture, training, common conditions of service, consumer view, and engineering the patient process. Moreover, the strengths and weaknesses of the model were considered from the viewpoint of the patient, the staff, the public health, and finance. It is noted that the concept of patient-focused care, where related services are brought to the patient, instead of the traditional model of making the patient do the work, has demonstrable effect.
