Dermatology outpatient case-mix survey for all Welsh Trusts, 2007.
Background In 2006 a U.K. government White Paper recommended making NHS care in England more accessible by shifting services from secondary care into community settings. There is a shortage of contemporary activity data for U.K. dermatology units to allow benchmarking for service development. This study will not only provide useful comparative data for the future in Wales, but will also serve to highlight the impact of changes made in England. Objective To provide an overview of 1 week's dermatology outpatient activity for the whole of Wales. Methods All dermatology units in Wales collected data for 1 week in early 2007. The case mix, appropriateness of referral, requirement for surgery or second-line therapies and follow-up requirements were all determined. Results A total of 2142 patients were seen. Of new patients, 21% had skin cancer. Seventeen per cent of skin cancers had no diagnosis suggested by the general practitioner (GP) and 10% of basal cell carcinomas, 33% of squamous cell carcinomas and 17% of malignant melanomas were inappropriately diagnosed. In all, 26% of new patients had benign lesions, and this group caused the greatest diagnostic difficulty for GPs. Seventy-one per cent of these patients were diagnosed, reassured and discharged at their first visit without the need for biopsy or surgery. Thirty-seven per cent of new patients required surgery, of which 21% required complex intervention. Twenty-six per cent of follow-up patients were receiving second-line therapies. The new to follow-up ratio varied considerably according to diagnosis, the mean ratio being 1 : 0.21 for benign lesions through to 1 : 5.53 for psoriasis. This highlights the inappropriate nature of a 'one fits all' ratio. The majority of follow-up patients in secondary care required this level of input for monitoring of cancer, complex second-line therapies or surgery. Conclusions This study provides evidence to support logical planning of dermatological services and to assess the impact of proposed changes on different healthcare systems in the U.K.
