Assessing Diagnostic Skill in Dermatology: A Comparison Between General Practitioners and Dermatologists

In a 2005 retrospective study involving 656 GP referrals to dermatology services, it was found that general practitioners (GPs) had a 42% agreement rate with dermatologists on clinical diagnoses and a 24% agreement rate when histological confirmation was available, compared to dermatologists' 77% agreement rate. GPs were more accurate in diagnosing conditions like acne, warts, alopecia areata, and benign naevi but had difficulty with skin tumors and other specific skin conditions. The study, with its large sample size and real-world context, suggested the need for better dermatological training for GPs, particularly in skin cancer diagnosis, and recommended a low threshold for specialist referrals. Despite its retrospective nature and the lack of a provisional diagnosis in 42% of cases, the study provided valuable insights into the diagnostic discrepancies between GPs and dermatologists.
