          Abstract

          Background

          There are increasing expectations on primary care doctors to shoulder a bigger share of care for patients with common dermatological problems in the community. This study examined the learning outcomes of a short postgraduate course in dermatology for primary care doctors.

          Methods

          A self-reported questionnaire developed by the research team was sent to the Course graduates. A retrospective design was adopted to compare their clinical practice characteristics before and after the Course. Differences in the ratings were analysed using the nonparametric Wilcoxon signed rank test to evaluate the effectiveness of the Course in various aspects.

          Results

          Sixty-nine graduates replied with a response rate of 42.9% (69/161). Most were confident of diagnosing (91.2%) and managing (88.4%) common dermatological problems after the Course, compared to 61.8% and 58.0% respectively before the Course. Most had also modified their approach and increased their attention to patients with dermatological problems. The number of patients with dermatological problems seen by the graduates per day showed significant increase after the Course, while the average percentage of referrals to dermatologists dropped from 31.9% to 23.5%. The proportion of graduates interested in following up patients with chronic dermatological problems increased from 60.3% to 77.9%.

          Conclusions

          Graduates of the Course reported improved confidence, attitudes and skills in treating common dermatological problems. They also reported to handle more patients with common dermatological problems in their practice and refer fewer patients.

          Dermatology in primary care: Prevalence and patient disposition.

          Cutaneous disease is commonly encountered in primary care. The frequency of patients presenting to primary care physicians with skin disease and their eventual disposition is not well studied. The purpose of this study was to determine the prevalence of patients seen with skin disease in a primary care setting and the likelihood of their referral to a dermatologist. The impact the primary care provider had on the quality of skin care was also examined. A retrospective chart review was performed of patients seen during a 2-year period at a general medicine clinic within the University of Miami and upon referral to a University of Miami dermatology office. Data were obtained on the prevalence of skin disease, dispositions of referral, diagnoses made, and procedures performed. During a 2-year period, 36.5% of patients who presented to their primary care physician had at least one skin problem. Of 208 patients with skin disease, in 58.7% (122/208) it was their chief complaint. A wide range of diagnoses were made by the primary care physician, with a limited number of diagnostic procedures performed. Of the 37.5% of patients referred to a dermatologist, 68% were referred on initial evaluation. Diagnoses made by the primary care physician were concordant with that made by the dermatologists 57% of the time. Patients frequently see their primary care physician for skin disease. A large percentage are referred to dermatologists, often for a biopsy of a suspect lesion, to confirm a suspected diagnosis, or to establish a diagnosis of lesions of unknown origin.

            Increase in the sensitivity for melanoma diagnosis by primary care physicians using skin surface microscopy.

            Skin surface microscopy (oil epiluminescence microscopy, dermoscopy, dermatoscopy) has been shown to increase the diagnostic accuracy of melanoma. However, all studies to date have been in an expert setting. To determine whether primary care physicians (PCP) (general practitioners) could improve their melanoma diagnosis using surface microscopy after a short education intervention. Seventy-four practising PCP completed a pretest of 50 melanomas and 50 atypical non-melanoma pigmented skin lesions (PSL) containing matched clinical and surface microscopy photographs. PCP were randomized between a surface microscopy education intervention or control group, followed by an identical post-test. Following training there was a significant improvement in the post-test vs. pretest in both clinical melanoma diagnosis (62.7% vs. 54.6%; P = 0.007) and surface microscopy melanoma diagnosis (75.9% vs. 57.8%; P = 0.000007). No difference was found in the control group between the post-test vs. pretest clinical melanoma diagnosis (53.7% vs. 50.6%; P = 0.21) or the surface microscopy melanoma diagnosis (54.8% vs. 52.9%; P = 0.56). Following training there was a significant improvement in the diagnosis of melanoma using surface microscopy vs. clinical diagnosis (75.9% vs. 62.7%; P = 0.000007), which was absent in the control group (54.8% vs. 53.7%; P = 0.59). No significant difference was found in clinical vs. surface microscopy post-test results for non-melanoma PSL in either the intervention group or control group. Improvement in the sensitivity for the diagnosis of melanoma with surface microscopy was seen without a decrease in specificity; this indicated that the effect should occur without increasing the number of needless excisions. All PCP in countries where melanoma leads to significant mortality should be trained in skin surface microscopy.

              Diagnosing and managing cutaneous pigmented lesions: primary care physicians versus dermatologists.

              Primary care physicians (PCPs) are often expected to screen for melanomas and refer patients with suspicious pigmented lesions to dermatologists. To assess whether there is a difference between dermatologists and PCPs in accurately diagnosing melanoma and appropriately managing (based on decisions to refer/biopsy) suspicious pigmented lesions. A survey based on a random sample of 30 photographs of pigmented lesions with known pathology was administered to 101 dermatologists and 115 PCPs from October 2001 to January 2003. Likelihoods that a photographed lesion was melanoma and that the lesion should be biopsied/referred were scored on a 1 to 10 scale. Accuracy of melanoma diagnosis and appropriateness of pigmented lesion management were compared between dermatologists and PCPs by using the areas under (AUC) the receiver operating characteristic (ROC) curves. Dermatologists were superior to PCPs in diagnosing melanomas (AUC 0.89 vs 0.80, P<.001) and appropriately managing pigmented lesions (AUC .84 vs 0.76, P<.001). PCPs who tended to biopsy lesions themselves did better at managing pigmented lesions than PCPs who did not perform biopsies. Dermatology training during residency did not significantly improve the diagnostic accuracy of PCPs nor their management of pigmented lesions. Dermatologists have both better diagnostic accuracy and ability to manage pigmented lesions than PCPs. Yet, there is a shortage of dermatologists to meet the demand of accurate melanoma screening. More innovative strategies are needed to better train PCPs and enhance skin cancer screening.
