title: Prioritizing dermatoses: rationally selecting guideline topics.
abstract: BACKGROUND
  Clinical practice guideline (CPG) development starts with selecting appropriate topics, as resources to develop a guideline are limited. However, a standardized method for topic selection is commonly missing and the way different criteria are used to prioritize is not clear.
  
  
  OBJECTIVE
  To select and prioritize dermatological topics for CPG development and elucidate criteria dermatologists find important in selecting guideline topics.
  
  
  METHODS
  All 410 dermatologists in the Netherlands were asked to create a top 20 of dermatological topics for which a guideline would be desirable, regardless of existing guidelines. They also rated, on a 5-point Likert scale, 10 determinative criteria derived from a combined search in literature and across (inter)national guideline developers. Top 20 topics received scores ranging from 0.01 to 0.2 and combined scores yielded a total score.
  
  
  RESULTS
  The 118 surveys (response 29%) identified 157 different topics. Melanoma, squamous cell carcinoma, basal cell carcinoma, psoriasis and atopic dermatitis are top priority guideline topics. Venous leg ulcer, vasculitis, varicose veins, urticaria, acne, Lyme borreliosis, cutaneous lupus erythematosus, pruritus, syphilis, lymphoedema, decubitus ulcer, hidradenitis suppurativa, androgenic alopecia and bullous pemphigoïd complete the top 20. A further 15 topics have overlapping confidence intervals. Mortality and healthcare costs are regarded as less important criteria in topic selection (P < 0.04), than other criteria like the potential to reduce unwanted variation in practice.
  
  
  CONCLUSIONS
  Dermatological professional organizations worldwide succeeded in developing guidelines for all top 20 topics. Respondents mostly agree with (inter)national guideline programmes and literature concerning the criteria important to selecting guideline topics.
