Study Limitations
The present study has several limitations. First, there was an unknown time lag between the FBSEs and physician self-reported surveys. Similarly, there was a variable time lag between the patient examination encounter and subsequent telephone survey. Both the physician and patient survey data may have been affected by recall bias. Second, patients were not asked directly whether an FBSE had been conducted. Furthermore, patients may not have appreciated whether the body part examined was part of the FBSE or another examination. Also, screenings often were not recorded in the medical record, assuming that the patient report and/or physician report was more accurate than the medical record.
Our study also was limited by demographics; our patient sample was largely comprised of White, educated, US adults, potentially limiting the generalizability of our findings. Conversely, a notable strength of our study was that our participants were recruited from 4 geographically diverse centers. Furthermore, we had a comparatively large sample size of patients and physicians. Also, the independent assessment of provider-reported examinations, objective assessment of medical records, and patient reports of their encounters provides a strong foundation for assessing the independent contributions of each data source.
CONCLUSION
Our study highlights the challenges future studies face in promoting skin cancer screening in the primary care setting. Our findings underscore the need for a standardized FBSE as well as clear clinical expectations regarding skin cancer screening that is expected of PCPs.
As long as skin cancer screening rates remain low in the United States, patients will be subject to potential delays and missed diagnoses, impacting morbidity and mortality.8 There are burgeoning resources and efforts in place to increase skin cancer screening. For example, free validated online training is available for early detection of melanoma and other skin cancers (https://www.visualdx.com/skin-cancer-education/).39-42 Future directions for bolstering screening numbers must focus on educating PCPs about skin cancer prevention and perhaps narrowing the screening population by age-appropriate risk assessments.
