A large skin cancer screening quality initiative : Description and first-year outcomes
Menée aux Etats-Unis auprès de 333 735 patients adultes ayant consulté un médecin généraliste en 2014, cette étude évalue l'effet, sur l'incidence de mélanomes et sur la profondeur des lésions cancéreuses au diagnostic, d'une intervention comportant une campagne d'information encourageant le dépistage annuel des cancers de la peau par examen cutané de l'ensemble du corps, l'inclusion de ce type d'examen dans le dossier médical électronique ainsi que des séances pratiques pour les médecins généralistes
Importance : The lack of prospective randomized clinical trials demonstrating that full-body skin examination (FBSE) reduces melanoma morbidity or mortality has prompted an “I” rating from the United States Preventive Services Task Force for population-based skin cancer screening. More data on these screening programs are needed.
Objectives : To describe a skin cancer screening quality initiative in a large health care system and to determine if the intervention was associated with screening of a demographically higher-risk population than previous screening programs and if melanoma incidence and thickness differed in screened vs unscreened patients.
Design, Setting, and Participants : This observational evaluation of a prospectively implemented quality initiative was conducted in a large health care system in western Pennsylvania (University of Pittsburgh Medical Center, UPMC) among adults seen in an office visit by a UPMC-employed primary care physician (PCP) in 2014.
Interventions Implementation of a campaign promoting annual skin cancer screening by FBSE, including training of PCPs, promotion of the initiative to physicians and patients, and modification of the electronic health record (EHR) to include FBSE as a recommended preventive service for patients 35 years or older.
Main Outcomes and Measures : Characteristics of screened and unscreened patients and melanomas detected among them.
Results : Of 333 735 adult patients seen in an office visit by PCPs in 2014, 53 196 patients (15.9% of the screen-eligible population) received an FBSE, and 280 539 did not. Screened patients were slightly older (median age, 60 vs 57 years; P < .001) but did not differ significantly by sex (43.2% vs 43.1% men; P = .49) from the unscreened population. Fifty melanomas were diagnosed in screened patients and 104 melanomas were diagnosed in unscreened patients. Screened patients were more likely than unscreened patients to be diagnosed with melanoma (adjusted risk ratio [RR], 2.4; 95% CI, 1.7-3.4; P < .001) and to have a thinner invasive melanoma (median thickness, 0.37 mm vs 0.65 mm; P < .001). The incidence of melanoma lesions 1 mm or thicker was similar in screened vs unscreened patients (adjusted RR, 0.7; 95% CI, 02.-2.2; P = .52).
Conclusions and Relevance : Large-scale screening for melanoma within a United States health care system is feasible and can result in increased detection of thinner melanomas. This intervention also resulted in screening of a higher proportion of men and an older patient population than previous screening interventions in which younger individuals and women predominated.
