RESUMO
Melanoma-screening examinations support early diagnosis, yet there is a national shortage of dermatologists and most at-risk patients lack access to dermatologic care. Primary care physicians (PCPs) in the United States often bridge these access gaps, and thus, play a critical role in the early detection of melanoma. However, most PCPs do not offer skin examinations. We conducted a systematic review and searched Ovid MEDLINE, EMBASE, and the Cochrane Library from 1946 to July 2019 to identify barriers for skin screening by providers, patients, and health systems following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Of 650 abstracts initially identified, 111 publications were included for full-text review and 48 studies met the inclusion criteria. Lack of dermatologic training (89.4%), time constraints (70%), and competing comorbidities (51%) are the most common barriers reported by PCPs. Low perceived risk (69%), long delays in appointment (46%), and lack of knowledge about melanoma (34.8%) are most frequently reported patient barriers. Qualitative reported barriers for health system are lack of public awareness, social prejudice leading to tanning booth usage, public surveillance programs requiring intensive resources, and widespread ABCD evaluation causing delays in seeking medical attention for melanomas. Numerous barriers remain that prevent the implementation of skin screening practices in clinical practice. A multi-faceted combination of efforts is essential for the execution of acceptable and effective skin cancer-screening practices, thus, increasing early diagnosis and lowering mortality rates and burden of disease for melanoma.
