Scientific title	Does a multifaceted intervention improve the competence in the diagnosis of skin cancer by general practitioners? A randomised controlled trial
Study acronym	minSKIN
Study objectives	A multifaceted intervention with general practitioners (GPs) (including technical equipment and a continuous feedback on skin lesions) leads to an improved competence in the diagnosis of skin cancer by GPs. On 06/09/2013 the target number of participants was changed from 60 to 78.
Ethics approval(s)	The ethics committee of the Kanton Zurich (Kantonale Ethik-Kommission Zürich) approved on the 01/03/2011 (KEK-ZH-NR: 2010-0384/5)
Health condition(s) or problem(s) studied	Skin cancer
Intervention	Both groups: Dermatological training course (duration: one day) Intervention group: 1. Magnifying glass (Lumio loupe) with integrated polarised light source allowing subsurface examination 2. Digital consumer camera 3. GPs send pictures of skin lesions to the study dermatologist and get continuous problem based feedback and teaching based on these pictures Control group: No further intervention, GPs provide usual care
Intervention type	Other
Primary outcome measure	Competence in the diagnosis of skin cancer by GPs, measured as the percentage of correctly classified pictures of skin lesions. The measures will be assessed at baseline before the dermatological workshop (T0), immediately after the dermatological workshop (T1) and after one year of continuous feedback with the intervention group (T2).
Secondary outcome measures	1. Histopathology of excised skin lesions 2. Age, sex and skin type of patients with skin lesions
Overall study start date	01/04/2011
Completion date	31/08/2012
