FBSEs in Patient Medical Records
When comparing PCP-reported FBSE and report of FBSE in patient medical records, there was a 39.0% increased odds of the patient medical record indicating FBSE when physicians reported conducting an FBSE with greater frequency (95% CI, 1.30-1.48; P<.001)(eTable 1). When examining PCP-reported never vs almost always conducting an FBSE, a report of almost always was associated with 79.0% increased odds of the patient medical record indicating that an FBSE was conducted (95% CI, 1.28-2.49; P=.001). The raw percentage of the patient medical record indicating an FBSE was conducted when the PCP reported having never conducted an FBSE was 17% and 26% when the PCP reported having almost always conducted an FBSE.
When comparing the patient-reported body part examined with patient FBSE medical record documentation, an indication of yes for FBSE on the patient medical record was associated with a considerable increase in odds that patients reported a particular body part was examined (back: 91.4% [95% CI, 1.59-2.31; P<.001]; abdomen: 75.0% [95% CI, 1.45-2.11; P<.001]; backs of legs: 91.6% [95% CI, 1.56-2.36; P<.001])(eTable 2). The raw percentages of patients who reported having their back, abdomen, and backs of legs examined vs not examined when the patient medical record indicated an FBSE was completed were 24% vs 14%, 23% vs 15%, and 26% vs 16%, respectively. An increase in patient-reported level of undress was associated with a 57.0% increased odds of their medical record indicating an FBSE was conducted (95% CI, 1.45-1.70; P<.001).
COMMENT How PCPs Perform FBSEs Varies
We found that PCPs performed FBSEs with variable frequency, and among those who did, the patient report of their examination varied considerably (Table 1). There appears to be considerable ambiguity in each of these means of determining the extent to which the skin was inspected for skin cancer, which may render the task of improving such inspection more difficult. We asked patients whether their back, abdomen, and backs of legs were examined as an assessment of some of the variety of areas inspected during an FBSE. During a general well-visit appointment, a patient’s back and abdomen may be examined for multiple reasons. Patients may have misinterpreted elements of the pulmonary, cardiac, abdominal, or musculoskeletal examinations as being part of the FBSE. The back and abdomen—the least specific features of the FBSE—were reported by patients to be the most often examined. Conversely, the backs of the legs—the most specific feature of the FBSE—had the lowest odds of being examined (Table 1).
In addition to the potential limitations of patient awareness of physician activity, our results also could be explained by differences among PCPs in how they performed FBSEs. There is no standardized method of conducting an FBSE. Furthermore, not all medical students and residents are exposed to dermatology training. In our sample of 53 physicians, 79% had reported receiving dermatology training; however, we did not assess the extent to which they had been trained in conducting an FBSE and/or identifying malignant lesions. In an American survey of 659 medical students, more than two-thirds of students had never been trained or never examined a patient for skin cancer.21 In another American survey of 342 internal medicine, family medicine, pediatrics, and obstetrics/gynecology residents across 7 medical schools and 4 residency programs, more than three-quarters of residents had never been trained in skin cancer screening.22 Our findings reflect insufficient and inconsistent training in skin cancer screening and underscore the need for mandatory education to ensure quality FBSEs are performed in the primary care setting.
Frequency of PCPs Performing FBSEs
Similar to prior studies analyzing the frequency of FBSE performance in the primary care setting,16,19,23,24 more than half of our PCP sample reported sometimes to never conducting FBSEs. The percentage of physicians who reported conducting FBSEs in our sample was greater than the proportion reported by the National Health Interview Survey, in which only 8% of patients received an FBSE in the prior year by a PCP or obstetrician/gynecologist,16 but similar to a smaller patient study.19 In that study, 87% of patients, regardless of their skin cancer history, also reported that they would like their PCP to perform an FBSE regularly.19 Although some of our patient participants may have declined an FBSE, it is unlikely that that would have entirely accounted for the relatively low number of PCPs who reported frequently performing FBSEs.
Documentation in Medical Records of FBSEs
Compared to PCP self-reported performance of FBSEs, considerably fewer PCPs marked the patient medical record as having completed an FBSE. Among patients with medical records that indicated an FBSE had been conducted, they reported higher odds of all 3 body parts being examined, the highest being the backs of the legs. Also, when the patient medical record indicated an FBSE had been completed, the odds that the PCP reported an FBSE also were higher. The relatively low medical record documentation of FBSEs highlights the need for more rigorous enforcement of accurate documentation. However, among the cases that were recorded, it appeared that the content of the examinations was more consistent.
Benefits of PCP-Led FBSEs
Although the USPSTF issued an I rating for PCP-led FBSEs,14 multiple national medical societies, including the American Cancer Society,25 American Academy of Dermatology,26 and Skin Cancer Foundation,27 as well as international guidelines in Germany,28 Australia,29,30 and New Zealand,31 recommend regular FBSEs among the general or at-risk population; New Zealand and Australia have the highest incidence and prevalence of melanoma in the world.8 The benefits of physician-led FBSEs on detection of early-stage skin cancer, and in particular, melanoma detection, have been documented in numerous studies.30,32-38 However, the variability and often poor quality of skin screening may contribute in part to the just as numerous null results from prior skin screening studies,15 perpetuating the insufficient status of skin examinations by USPSTF standards.14 Our study underscores both the variability in frequency and content of PCP-administered FBSEs. It also highlights the need for standardization of screening examinations at the medical student, trainee, and physician level.
