Skin cancer screening in primary care: prevalence and barriers.

BACKGROUND: Skin cancer incidence is increasing, but whether primary care providers routinely screen for skin cancer is not known. OBJECTIVE: We assessed whether primary care practitioners are performing skin cancer screening within the context of primary care and whether barriers exist that might act as impediments to the implementation of this practice. METHODS: A total of 465 primary care providers belonging to their respective county medical societies in either New Haven County, Connecticut, or Miami-Dade County, Florida were randomly selected and surveyed by mailed questionnaire regarding their skin cancer screening practices. RESULTS: Only 31% of responding physicians reported performing skin cancer screening on all of their adult patients. Of those not performing skin cancer screening on all adult patients, only 31% report performing screening on high-risk patients. Almost half of physicians reported that they do not perform skin cancer screening. We found that physicians' lack of confidence in identifying suspect lesions was a common barrier. Fear of patient embarrassment, inadequate lighting, or lack of studies demonstrating mortality benefits were not frequent deterrents. Furthermore, there was no statistical difference in screening rates between the more northern latitude and the more southern latitude. CONCLUSION: Skin cancer screening is not being performed within the context of primary care visits. Barriers exist that may impede skin cancer screening.     

Factors influencing skin cancer excision rates in Scottish primary care

Skin cancer incidence rates are rising in the UK, yet many areas are experiencing a shortage of dermatologists. We sought to compare skin cancer excision rates between general practice (GP) surgeons to identify factors associated with good practice, through a retrospective analysis of GP skin cancer histopathology reports in three Scottish Health Boards over a 4‐year period. Postal questionnaires were used to explore factors affecting surgeons’ excision rates. GPs excised 895 skin cancers (4.5% of the 19 853 regional total) during the period. Of the basal cell carcinomas, 308 would be classified as low‐risk by current National Institute for Health and Care Excellence criteria. Of the returned questionnaires, 58 accounted for 631 (70.5%) of the excised skin cancers. Analysing completeness of skin cancer excision, there was a statistically significant difference between GPs performing excision on ≥ 11 lesions/month compared with those performing excision on ≤ 10/month. Policymakers may wish to consider systems to facilitate low‐risk patients being treated by GPs who undertake frequent surgical procedures.     

Parental knowledge and practice of primary skin cancer prevention: gaps and solutions

Over the past two decades there have been significant efforts in the United States to heighten awareness about skin cancer. Our goal was to assess parental knowledge, practice, and source of information about sun protection for their children. A questionnaire was administered to 158 parents of children at a dermatology clinic and 96 parents of children at a pediatric clinic (n=254). The survey included four parts: demographics, knowledge about skin cancer, sun protection practices, and sources of sun protection information. The mean knowledge score was 61% correct. Independent predictors of a higher score were fewer children and being a health care or other professional (p < 0.03). Independent predictors of parental sunscreen use were higher knowledge score, younger age, and fewer lifetime sunburns (p < 0.03); predictors of sunscreen use for children were higher knowledge score and fairer skin (p < 0.03). The top sources of sun protection information ranked by respondents were television and magazines; the top desired sources were primary care physicians and dermatologists. The knowledge results suggest the need for increased education about skin cancer prevention. Because the media is a major information source, it is important to ensure that messages about sun risks/protection are correct. The respondents' desire to learn more from primary care physicians emphasizes the need to educate physicians about sun protection.     

Effectiveness of skin cancer screening programmes

Skin cancer, nonmelanoma skin cancer (NMSC) and cutaneous malignant melanoma (CMM), is the most frequent cancer worldwide. It is amenable to early detection, and screening for skin cancer has the potential to reduce mortality and morbidity. However, there are no recommendations for population-based skin cancer screening programmes due to the lack of evidence for the effectiveness from epidemiological studies. In 2008 the first nationwide screening programme for NMSC and CMM in the world was established in Germany. The decision for implementing such a programme was based on the results and evidence of a pilot study that was conducted from 2003 to 2004. The pilot study revealed that a population-based screening programme for skin cancer is feasible and effective. Careful evaluation of the nationwide programme is crucial to generate strong evidence for long-term public health benefits.     

Measuring the quality of skin cancer management in primary care: A scoping review

Skin cancer is a growing global problem and a significant health and economic burden. Despite the practical necessity for skin cancer to be managed in primary care settings, little is known about how quality of care is or should be measured in this setting. This scoping review aimed to capture the breadth and range of contemporary evidence related to the measurement of quality in skin cancer management in primary care settings. Six databases were searched for relevant texts reporting on quality measurement in primary care skin cancer management. Data from 46 texts published since 2011 were extracted, and quality measures were catalogued according to the three domains of the Donabedian model of healthcare quality (structure, process and outcome). Quality measures within each domain were inductively analysed into 13 key emergent groups. These represented what were deemed to be the most relevant components of skin cancer management as related to structure, process or outcomes measurement. Four groups related to the structural elements of care provision (e.g. diagnostic tools and equipment), five related to the process of care delivery (e.g. diagnostic processes) and four related to the outcomes of care (e.g. poor treatment outcomes). A broad range of quality measures have been documented, based predominantly on articles using retrospective cohort designs; systematic reviews and randomised controlled trials were limited.     

Melanoma screening behavior among primary care physicians

The incidence of malignant melanoma is rising concomitantly with dramatic changes in our healthcare system. Primary care physicians (PCPs) are responsible for an increasing number of skin-related healthcare visits. Therefore, PCPs must be on the forefront of early detection of suspicious pigmented lesions. Understanding the PCPs' screening and referral patterns for pigmented lesions is the first step in ensuring that atypical pigmented lesions will be properly evaluated within the confines of the present healthcare system. To develop a better understanding of how PCPs (internists, family practitioners, and pediatricians) manage pigmented lesions in their practice, we mailed a 28-question survey to 999 PCPs in Connecticut. Fewer than half of the 248 respondents indicated they "often" performed full skin examinations. However, when suspicious lesions were found, most PCPs referred patients to a dermatologist for a biopsy of the lesion. PCPs did not feel pressure from managed care companies to limit these referrals. However, many PCPs did not feel highly confident in their ability to recognize melanoma and thought their training was not adequate to prepare them to diagnose and manage pigmented lesions. Family practitioners were more likely than internists and pediatricians to manage suspicious pigmented lesions and to perform a biopsy on their own. Family practitioners also were more confident in performing these tasks and were more likely to think their training in these areas was adequate. Very few PCPs reported sending their biopsy specimens to a dermatopathology laboratory. In fact, many PCPs seemed unaware of who interpreted the histopathology. PCPs do not emphasize full skin examinations in their practice and seem unaware of the advantages inherent in using dermatopathologists in the histopathologic interpretation of pigmented lesions. Furthermore, lack of confidence on the part of PCPs, as well as their concern about adequate training in the management of pigmented lesions, suggest there is need for improvement in the education of primary care residents and physicians.     

College students' knowledge and attitudes about cancer and perceived risks of developing skin cancer

Skin cancer is the most commonly occurring cancer in the United States. Primary prevention practices for skin cancer are fully documented in the literature for reducing the damaging effects of ultraviolet radiation on skin. Late adolescents, inherent to their young age and risk-taking behaviors, are more likely to sunbathe. The cancer attitudes and suntanning knowledge, attitudes, perceptions, beliefs, and behaviors among college students were examined. Gender-specific interventions for educating this age group are recommended.     

Fundamentals of skin cancer/melanoma screening campaigns

There is increased world-wide concern about the rising incidence of melanoma and non-melanoma skin cancer. Screening theoretically reduces death and morbidity from skin cancer/melanoma. Visual examination of the skin is a rapid, safe and inexpensive screening tool. In this review the fundamentals of early disease detection before implementation of a public-health screening programme are critically analysed with reference to the skin cancer/melanoma, epidemic. It is concluded that skin cancer/melanoma fulfils, for the most part, the criteria enunciated by Wilson and Jungner in 1968. However, information about the effect of screening on reducing incidence and mortality is still lacking. Future research should focus on methods of improving compliance and on the costs and benefits of such screening programmes.     

Follow-up and evaluation of skin cancer screening in British Columbia.

BACKGROUND: Skin cancer screening is thought to be a useful public health tool for the early detection of skin cancers. However, few studies have reported on follow-up and outcome of subjects who have a positive screen. OBJECTIVE: The aims of this study were to evaluate attendance at skin cancer screening clinics in British Columbia for the period 1994 and 1995 and to assess follow-up outcome among participants who were identified to have a potentially serious skin lesion that warranted further medical review. METHODS: A self-administered questionnaire was sent to participants screening positive for skin cancer and to their attending physicians. RESULTS: Five hundred twenty people were screened. Of these, 105 were referred for evaluation of a potential malignancy or precursor lesion. One melanoma, 3 basal cell carcinomas, 4 atypical nevi, and 1 actinic keratosis were histologically confirmed in 76 referred participants for whom follow-up information was available. The positive predictive values ranged from 17% to 89% depending on the screening diagnosis. Several false-positive results and one false-negative result were observed. Reasons for not seeking recommended follow-up were addressed. CONCLUSIONS: Our yield and positive predictive values for different screening diagnoses were virtually identical to those previously reported in larger US studies. Improved communication between screening physicians and screening participants may improve follow-up rates in those people who would benefit from further medical care.
