Text Description.

The analytic framework depicts the five Key Questions (KQs) described in the research plan. Specifically, it illustrates the following questions: whether counseling patients on skin cancer prevention improves intermediate outcomes (sunburn or precursor lesions) or skin cancer outcomes (melanoma, squamous cell, or basal cell carcinoma incidence, morbidity, or mortality) (KQ 1); whether primary care–relevant counseling interventions improve skin cancer prevention behaviors (e.g., reduced sun exposure, sunscreen use, use of protective clothing, avoidance of indoor tanning, and skin self-examination) (KQ 2); the harms of counseling interventions for skin cancer prevention (e.g., increased time in the sun, reduced physical activity, vitamin D deficiency, and anxiety) (KQ 3); the association between skin self-examination and skin cancer outcomes (melanoma, squamous cell, or basal cell carcinoma incidence, morbidity, or mortality) (KQ 4); and the harms of skin self-examination (KQ 5).

  1. Does counseling patients in skin cancer prevention improve a) intermediate outcomes (sunburn or precursor lesions) or b) skin cancer outcomes (melanoma, squamous cell, or basal cell carcinoma incidence, morbidity, or mortality)?
  2. Do primary care–relevant counseling interventions improve skin cancer prevention behaviors (e.g., reduced sun exposure, sunscreen use, use of protective clothing, avoidance of indoor tanning, and skin self-examination)?
  3. What are the harms of counseling interventions for skin cancer prevention (e.g., increased time in the sun, reduced physical activity, vitamin D deficiency, and anxiety)?
  4. What is the association between skin self-examination and skin cancer outcomes (melanoma, squamous cell, or basal cell carcinoma incidence, morbidity, or mortality)?
  5. What are the harms of skin self-examination?

*Key Questions (KQs) 4 and 5 will only be addressed systematically if there is sufficient evidence from KQs 1 to 3 that behavioral counseling increases skin self-examination behavior.

  1. What is the association between sunscreen use, sun exposure, indoor tanning, skin self-examination, and a) skin cancer incidence, morbidity, or mortality or b) other health outcomes?

The Proposed Research Approach identifies the study characteristics and criteria that the Evidence-based Practice Center will use to search for publications and to determine whether identified studies should be included or excluded from the Evidence Review. Criteria are overarching as well as specific to each of the KQs.

  Include Exclude
Population
  • Persons of any age
  • Parents/caregivers of children
 Persons with prior history of skin cancer or who are otherwise under surveillance for skin cancer because of known increased risk
Settings
  • Any setting linked with primary care health care delivery (e.g., hospital, home, clinic)
  • Studies conducted in countries categorized as “Very High” on the Human Development Index (as defined by the United Nations Development Programme)
 Settings not affiliated with primary care, such as community, worksites, child care, school, or recreational/tourism settings
Intervention
  • Stand-alone or multicomponent/multidimensional interventions aimed at improving sun protection behaviors or teaching skin self-examination
  • Intervention must be initiated in, conducted in, or referable from primary care
  • Interventions may include, but are not limited to: individual or group counseling, peer counseling, home visits, structured education, technology- or computer-based support, or distribution of written materials
  • Interventions may be conducted by, but are not limited to: nurses/nurse practitioners, lay health workers, or physicians
  • Health care system interventions (e.g., staff training)
  • Interventions not referable from primary care (occupational, recreational/ tourism, policy-level)
  • Mass media campaigns
  • Community interventions not affiliated with primary care
  • Multicomponent interventions for which the impact of primary care–relevant counseling cannot be isolated
Comparison Usual care, no intervention, waitlist, or minimal intervention Another skin cancer counseling intervention
Outcomes KQs 1, 4: Skin cancer outcomes: melanoma, basal cell carcinoma, or squamous cell carcinoma incidence, morbidity, or mortality

Intermediate outcomes: sunburn, nevi, and actinic keratosis

KQ 2: Behavioral outcomes: sunscreen use; time spent in the sun; shade-seeking; avoiding midday sun; avoiding indoor tanning; use of protective clothing, hats, or sunglasses; composite measures of sun protection behavior; skin self-examination behavior

KQ 3: Any harm of behavioral counseling interventions, such as anxiety, increased time spent in the sun, reduced physical activity, or vitamin D deficiency

KQ 5: Any harm of skin self-examination, including overdiagnosis and cosmetic or psychosocial harms

 Skin cancer metastasis or progression

KQs 1, 2, 4: Outcomes with less than 3 months followup after baseline assessment
Study design KQs 1, 2: Randomized, controlled trials and controlled clinical trials

KQs 3, 4, 5: Randomized, controlled trials; controlled clinical trials; and prospective cohort studies

 Observational studies, case series, case reports, narrative reviews, commentaries, editorials, and theses; qualitative studies; and ecologic studies
Language English  
Timing 2009 to present*  
Quality Fair or good (according to design-specific USPSTF criteria) Poor (according to design-specific USPSTF criteria)

* The USPSTF will continue to consider and use evidence that was included in its prior systematic reviews. For skin self-examination, the search period will begin with August 2005, the search date of the last USPSTF review on this topic.
