“…In contrast, specificity depends on experience, and it only increased for the most expert users, while dermoscopy led to a decrease in specificity in the group of novices (from 58.6 to 45.6%, p = 0.02). The data demonstrated in the present study support previously published prospective studies where dermoscopy has been shown to improve diagnostic accuracy among well-trained dermatologists [5], and improve detection of skin cancer even among nondermatologists and novices [6][7][8].…”

Dermoscopy Improves the Diagnostic Accuracy of Melanomas Clinically Resembling Seborrheic Keratosis: Cross-Sectional Study of the Ability to Detect Seborrheic Keratosis-Like Melanomas by a Group of Dermatologists with Varying Degrees of Experience

Background: Malignant melanomas mimicking seborrheic keratosis (SK-like MMs) carry the risk of delayed diagnosis and inadequate treatment. The value of dermoscopy to improve the correct detection of these mimickers has not been previously studied. Objective: To evaluate the diagnostic accuracy of clinically SK-like MMs with and without dermoscopy. Methods: Clinical and dermoscopic images of histopathologically proven SK-like MMs (n = 134) intermingled with other melanomas and benign tumors were randomly presented to clinicians with different levels of experience, blinded to the diagnosis and goal of the study. Each participant classified each lesion as melanoma or benign tumor. The clinical and clinical-dermoscopic diagnostic accuracies were measured separately. Results: Overall, 54 participants with a mean clinical experience of 15.8 years (SD 11.8) evaluated 231 tumors. Almost 40% of SK-like melanomas were clinically misclassified as benign tumor. Dermoscopy improved diagnostic accuracy for all participants, independently of experience, from 60.9 to 68.1% (p < 0.001), mostly

“…Use of dermoscopy as a triage tool for suspicious lesions has been advocated 42 . The Three-Point Checklist, a dermoscopic algorithm (described in the Online Appendix), has been shown to improve the ability of PCPs to triage suspicious lesions 40,[43][44][45][46][47] . Several studies have demonstrated improved diagnostic accuracy when teaching dermoscopy to nondermatologists, supporting that dermoscopy may be a valuable addition to a skin cancer education curriculum 44,47,48 .…”

Skin Cancer Education for Primary Care Physicians: A Systematic Review of Published Evaluated Interventions

et al. 2011

BACKGROUND: Early detection of melanoma may provide an opportunity to positively impact melanoma mortality. Numerous skin cancer educational interventions have been developed for primary care physicians (PCPs) to improve diagnostic accuracy. Standardized training is also a prerequisite for formal testing of melanoma screening in the primary care setting. OBJECTIVE: We conducted a systematic review to determine the extent of evaluated interventions designed to educate PCPs about skin cancer, including melanoma. DESIGN: Relevant studies in the English language were identified through systemic searches performed in MEDLINE, EMBASE, BIOSIS, and Cochrane through December 2010. Supplementary information was obtained from corresponding authors of the included studies when necessary. APPROACH: Studies eligible for inclusion formally evaluated skin cancer education interventions and were designed primarily for PCPs. Excluded studies lacked a specified training intervention, used decision-making software, focused solely on risk factor identification, or did not directly educate or assess participants. Twenty studies met the selection criteria. Data were extracted according to intervention content and delivery format, and study outcomes.KEY RESULTS: All interventions included instructions about skin cancer diagnosis, but otherwise varied in content. Curricula utilized six distinct educational techniques, usually incorporating more than one. Intervention duration varied from 12 min to over 6 h. Eight of the 20 studies were randomized trials. Most studies (18/20, 90%) found a significant improvement in at least one of the following five outcome categories: knowledge, competence, confidence, diagnostic performance, or systems outcomes. Competence was most commonly measured; no study evaluated all categories. Variability in study design, interventions, and outcome measures prevented correlation of outcomes with intervention characteristics. CONCLUSIONS: Despite the development of many isolated educational interventions, few have been tested rigorously or evaluated under sufficient standardized conditions to allow for quantitative comparison. Improved and rigorously tested skin cancer educational interventions for PCPs with outcome measures focusing on changes in performance are needed.

“…"While there are fewer studies on dermoscopy in general practice, all three that were undertaken in this context (one study with both general practitioners and inexperienced specialists or trainees) show a consistently improved sensitivity for the diagnosis of melanoma or the identification of suspicious lesions requiring biopsy [26,37,38]. It should be noted that all the studies cited were undertaken by clinicians with some training in dermoscopy (restricted to lectures or reading material in some studies).…”
