Clinical images are integral to dermatologic care, research, and education. Studies have highlighted the underrepresentation of images of skin of color (SOC) in educational materials,¹ clinical trials,² and research publications.³ Recognition of this disparity has ignited a call to action by dermatologists and dermatologic organizations to address the gap by improving the collection and use of SOC images.⁴ It is critical to remind dermatologists of the importance of properly obtaining informed consent and ensuring images are not used without a patient’s permission, as images in journal articles, conference presentations, and educational materials can be widely distributed and shared. Herein, we summarize current practices of clinical image storage and make general recommendations on how dermatologists can better protect patient privacy. Certain cultural and social factors in patients with SOC should be considered when obtaining informed consent and collecting images.

Clinical Image Acquisition

Consenting procedures are crucial components of proper image usage. However, current consenting practices are inconsistent across various platforms, including academic journals, websites, printed text, social media, and educational presentations.⁵

Current regulations for use of patient health information in the United States are governed by the Health Insurance Portability and Accountability Act (HIPAA)of 1996. Although this act explicitly prohibits use of “full face photographic images and any comparable images” without consent from the patient or the patient’s representative, there is less restriction regarding the use of deidentified images.⁶ Some clinicians or researchers may consider using a black bar or a masking technique over the eyes or face, but this is not always a sufficient method of anonymizing an image.

One study investigating the different requirements listed by the top 20 dermatology journals (as determined by the Google Scholar h5-index) found that while 95% (19/20) of journals stated that written or signed consent or permission was a requirement for use of patient images, only 20% (4/20) instructed authors to inform the patient or the patient’s representative that images may become available on the internet.⁵ Once an article is accepted for publication by a medical journal, it eventually may be accessible online; however, patients may not be aware of this factor, which is particularly concerning for those with SOC due to the increased demand for diverse dermatologic resources and images as well as the highly digitalized manner in which we access and share media.

Furthermore, cultural and social factors exist that present challenges to informed decision-making during the consenting process for certain SOC populations such as a lack of trust in the medical and scientific research community, inadequate comprehension of the consent material, health illiteracy, language barriers, or use of complex terminology in consent documentation.^7,8 Studies also have shown that patients in ethnic minority groups have greater barriers to health literacy compared to other patient groups, and patients with limited health literacy are less likely to ask questions during their medical visits.^9,10 Therefore, when obtaining informed consent for images, it is important that measures are taken to ensure that the patient has full knowledge and understanding of what the consent covers, including the extent to which the images will be used and/or shared and whether the patient’s confidentiality and/or anonymity are at risk.

Recommendations—We propose that dermatologists should follow these recommendations:

1. Encourage influential dermatology organizations such as the American Academy of Dermatology to establish standardized consenting procedures for image acquisition and use, including requirements to provide (a) written consent for all patient images and (b) specific details as to where and how the image may be used and/or shared.

2. Ensure that consent terminology is presented at a sixth-grade reading level or below, minimize the use of medical jargon and complex terms, and provide consent documentation in the patient’s preferred language.

3. Allow patients to take the consent document home so they can have additional time to comprehensively review the material or have it reviewed by family or friends.

4. Employ strategies such as teach-back methods and encourage questions to maximize the level of understanding during the consent process.

Clinical Image Storage

Clinical image storage procedures can have an impact on a patient’s health information remaining anonymous and confidential. In a survey evaluating medical photography use among 153 US board-certified dermatologists, 69.1% of respondents reported emailing or texting images between patients and colleagues. Additionally, 30.3% (46/152) reported having patient photographs stored on their personal phone at the time of the survey, and 39.1% (18/46) of those individuals had images that showed identifiable features, such as the patient’s face or a tattoo.¹¹

Although most providers state that their devices are password protected, it cannot be guaranteed that the device and consequently the images remain secure and inaccessible to unauthorized individuals. As sharing and viewing images continue to play an essential role in assessing disease state, progression, treatment response, and inclusion in research, we must establish and encourage clear guidelines for the storage and retention of such images.

Recommendations—We propose that dermatologists should follow these recommendations:

1. Store clinical images exclusively on password-protected devices and in password-protected files.

2. Use work-related cameras or electronic devices rather than personal devices, unless the personal device is being used to upload directly into the patient’s medical record. In such cases, use a HIPAA-compliant electronic medical record mobile application that does not store images on the application or the device itself.

3. Avoid using text-messaging systems or unencrypted email to share identifying images without clear patient consent.

Clinical Image Use

Once a thorough consenting process has been completed, it is crucial that the use and distribution of the clinical image are in accordance with the terms specified in the original consent. With the current state of technologic advancement, widespread social media usage, and constant sharing of information, adherence to these terms can be challenging. For example, an image initially intended for use in an educational presentation at a professional conference can be shared on social media if an audience member captures a photo of it. In another example, a patient may consent to their image being shown on a dermatologic website but that image can be duplicated and shared on other unauthorized sites and locations. This situation can be particularly distressing to patients whose image may include all or most of their face, an intimate area, or other physical features that they did not wish to share widely.

Individuals identifying as Black/African American, Latino/Hispanic, or Asian have been shown to express less comfort with providing permission for images of a nonidentifiable sensitive area to be taken (or obtained) or for use for teaching irrespective of identifiability compared to their White counterparts,¹² which may be due to the aforementioned lack of trust in medical providers and the health care system in general, both of which may contribute to concerns with how a clinical image is used and/or shared. Although consent from a patient or the patient’s representative can be granted, we must ensure that the use of these images adheres to the patient’s initial agreement. Ultimately, medical providers, researchers, and other parties involved in acquiring or sharing patient images have both an ethical and legal responsibility to ensure that anonymity, privacy, and confidentiality are preserved to the greatest extent possible.

Recommendations—We propose that dermatologists should follow these recommendations:

1. Display a message on websites containing patient images stating that the sharing of the images outside the established guidelines and intended use is prohibited.

2. Place a watermark on images to discourage unauthorized duplication.

3. Issue explicit instructions to audiences prohibiting the copying or reproducing of any patient images during teaching events or presentations.

Final Thoughts

The use of clinical images is an essential component of dermatologic care, education, and research. Due to the higher demand for diverse and representative images and the dearth of images in the medical literature, many SOC images have been widely disseminated and utilized by dermatologists, raising concerns of the adequacy of informed consent for the storage and use of such material. Therefore, dermatologists should implement streamlined guidelines and consent procedures to ensure a patient’s informed consent is provided with full knowledge of how and where their images might be used and shared. Additional efforts should be made to protect patients’ privacy and unauthorized use of their images. Furthermore, we encourage our leading dermatology organizations to develop expert consensus on best practices for appropriate clinical image consent, storage, and use.

Malignant melanoma, basal cell carcinoma, and squamous cell carcinoma account for approximately 40% of all neoplasms among the white population in the United States. Skin cancer is the most common malignancy in the United States.¹ However, despite this occurrence, there are limited data regarding skin cancer in individuals with skin of color (SOC). The 5-year survival rates for melanoma are 58.2% for black individuals, 69.7% for Hispanics, and 70.9% for Asians compared to 79.8% for white individuals in the United States.² Even though SOC populations have lower incidences of skin cancer—melanoma, basal cell carcinoma, and squamous cell carcinoma—they exhibit higher death rates.^3-7 Nonetheless, no specific guidelines exist to address sun exposure and safety habits in SOC populations.^6,8 Furthermore, current demographics suggest that by the year 2050, approximately half of the US population will be nonwhite.⁴ Paradoxically, despite having increased sun protection from greater amounts of melanin in their skin, black individuals are more likely to present with advanced-stage melanoma (eg, stage III/IV) compared to white individuals.^8-12 Furthermore, those of nonwhite populations are more likely to present with more advanced stages of acral lentiginous melanomas than white individuals.^13,14 Hispanics also face an increasing incidence of more invasive acral lentiginous melanomas.¹⁵ Overall, SOC patients have the poorest skin cancer prognosis, and the data suggest that the reason for this paradox is delayed diagnosis.¹

Although skin cancer is largely a preventable condition, the literature suggests that lack of awareness of melanoma among ethnic minorities is one of the main reasons for their poor skin cancer prognosis.¹⁶ This lack of awareness decreases the likelihood that an SOC patient would be alert to early detection of cancerous changes.¹⁷ Because educating at-risk SOC populations is key to decreasing skin cancer risk, this study focused on determining the efficacy of major knowledge-based interventions conducted to date.¹ Overall, we sought to answer the question, do knowledge-based interventions increase skin cancer awareness, knowledge, and protective behavior among people of color?

Methods

For this review, the Cochrane method of analysis was used to conduct a thorough search of PubMed articles indexed for MEDLINE (1994-2016), as well as a search of CINAHL (1997-2016), PsycINFO (1999-2016), and Web of Science (1965-2016), using a combination of more than 100 search terms including but not limited to skin cancer, skin of color, intervention, and ethnic skin. The search yielded a total of 52 articles (Figure). Following review, only 8 articles met inclusion criteria, which were as follows: (1) study was related to skin cancer in SOC patients, which included an intervention to increase skin cancer awareness and knowledge; (2) study included adult participants or adolescents aged 12 to 18 years; (3) study was written in English; and (4) study was published in a peer-reviewed journal. Of the remaining 8 articles, 4 were excluded due to the following criteria: (1) study failed to provide both preintervention and postintervention data, (2) study failed to provide quantitative data, and (3) study included participants who worked as health care professionals or ancillary staff. As a result, a total of 4 articles were analyzed and discussed in this review (Table).

Results

Robinson et al¹⁸ conducted 12 focus groups with 120 total participants (40 black, 40 Asian, and 40 Hispanic patients). Participants engaged in a 2-hour tape-recorded focus group with a moderator guide on melanoma and skin cancer. Furthermore, they also were asked to assess skin cancer risk in 5 celebrities with different skin tones. The statistically significant preintervention results of the study (χ²=4.6, P<.001) were as follows: only 2%, 4%, and 14% correctly reported that celebrities with a very fair skin type, a fair skin type, and very dark skin type, respectively, could get sunburn, compared to 75%, 76%, and 62% post-intervention. Additionally, prior to intervention, 14% of the study population believed that dark brown skin type could get sunburn compared to 62% of the same group postintervention. This study demonstrated that the intervention helped SOC patients better identify their ability to get sunburn and identify their skin cancer risk.¹⁸

Hernandez et al¹⁹ used a video-based intervention in a Hispanic community, which was in contrast to the multiracial focus group intervention conducted by Robinson et al.¹⁸ Eighty Hispanic individuals were recruited from beauty salons to participate in the study. Participants watched two 3-minute videos in Spanish and completed a preintervention and postintervention survey. The first video emphasized the photoaging benefits of sun protection, while the second focused on skin cancer prevention. Preintervention surveys indicated that only 54 (68%) participants believed that fair-skinned Hispanics were at risk for skin cancer, which improved to 72 (90%) participants postintervention. Furthermore, initially only 44 (55%) participants thought those with darker skin types could develop skin cancer, but this number increased to 69 (86%) postintervention. For both questions regarding fair and dark skin, the agreement proportion was significantly different between the preeducation and posteducation videos (P<.0002 for the fair skin question and P<.0001 for the dark skin question). This study greatly increased awareness of skin cancer risk among Hispanics,¹⁹ similar to the Robinson et al¹⁸ study.

In contrast to 2-hour focus groups or 3-minute video–based interventions, a study by Kundu et al¹⁷ employed a 20-minute educational class-based intervention with both verbal and visual instruction. This study assessed the efficacy of an educational tutorial on improving awareness and early detection of melanoma in SOC individuals. Photographs were used to help participants recognize the ABCDEs of melanoma and to show examples of acral lentiginous melanomas in white individuals. A total of 71 participants completed a preintervention questionnaire, participated in a 20-minute class, and completed a postintervention questionnaire immediately after and 3 months following the class. The study population included 44 black, 15 Asian, 10 Hispanic, and 2 multiethnic participants. Knowledge that melanoma is a skin cancer increased from 83.9% to 100% immediately postintervention (P=.0001) and 97.2% at 3 months postintervention (P=.0075). Additionally, knowledge that people of color are at risk for melanoma increased from 48.4% preintervention to 82.8% immediately postintervention (P<.0001). However, only 40.8% of participants retained this knowledge at 3 months postintervention. Because only 1 participant reported a family history of skin cancer, the authors hypothesized that the reason for this loss of knowledge was that most participants were not personally affected by friends or family members with melanoma. A future study with an appropriate control group would be needed to support this claim. This study shed light on the potential of class-based interventions to increase both awareness and knowledge of skin cancer in SOC populations.¹⁷

A study by Chapman et al²⁰ examined the effects of a sun protection educational program on increasing awareness of skin cancer in Hispanic and black middle school students in southern Los Angeles, California. It was the only study we reviewed that focused primarily on adolescents. Furthermore, it included the largest sample size (N=148) analyzed here. Students were given a preintervention questionnaire to evaluate their awareness of skin cancer and current sun-protection practices. Based on these results, the investigators devised a set of learning goals and incorporated them into an educational pamphlet. The intervention, called “Skin Teaching Day,” was a 1-day program discussing skin cancer and the importance of sun protection. Prior to the intervention, 68% of participants reported that they used sunscreen. Three months after completing the program, 80% of participants reported sunscreen use, an increase of 12% prior to the intervention. The results of this study demonstrated the unique effectiveness and potential of pamphlets in increasing sunscreen use.²⁰

Comment

Overall, various methods of interventions such as focus groups, videos, pamphlets, and lectures improved knowledge of skin cancer risk and sun-protection behaviors in SOC populations. Furthermore, the unique differences of each study provided important insights into the successful design of an intervention.

An important characteristic of the Robinson et al¹⁸ study was the addition of photographs, which allowed participants not only to visualize different skin tones but also provided them with the opportunity to relate themselves to the photographs; by doing so, participants could effectively pick out the skin tone that best suited them. Written SOC scales are limited to mere descriptions and thus make it more difficult for participants to accurately identify the tone that best fits them. Kundu et al¹⁷ used photographs to teach skin self-examination and ABCDEs for detection of melanoma. Additionally, both studies used photographs to demonstrate examples of skin cancer.^17,18 Recent evidence suggests the use of visuals can be efficacious for improving skin cancer knowledge and awareness; a study in 16 SOC kidney transplant recipients found that the addition of photographs of squamous cell carcinoma in various skin tones to a sun-protection educational pamphlet was more effective than the original pamphlet without photographs.²¹

In contrast to the Robinson et al¹⁸ study and Hernandez et al¹⁹ study, the Kundu et al¹⁷ study showed photographs of acral lentiginous melanomas in white patients rather than SOC patients. However, SOC populations may be less likely to relate to or identify skin changes in skin types that are different from their own. This technique was still beneficial, as acral lentiginous melanoma is the most common type of melanoma in SOC populations. Another benefit of the study was that it was the only study reviewed that included a follow-up postintervention questionnaire. Such data is useful, as it demonstrates how muchinformation is retained by participants and may be more likely to predict compliance with skin cancer protective behaviors.¹⁷

The Hernandez et al¹⁹ study is unique in that it was the only one to include an educational intervention entirely in Spanish, which is important to consider, as language may be a hindrance to participants’ understanding in the other studies, particularly Hispanics, possibly leading to a lack of information retention regarding sun-protective behaviors. Furthermore, it also was the only study to utilize videos as a method for interventions. The 3-minute videos demonstrated that interventions could be efficient as compared to the 2-hour in-class intervention used by Robinson et al¹⁸ and the 20-minute intervention used by Kundu et al.¹⁷ Additionally, videos also could be more cost-effective, as incentives for large focus groups would no longer be needed. Furthermore, in the Hernandez et al¹⁹ study, there was minimal to no disruption in the participants’ daily routine, as the participants were getting cosmetic services while watching the videos, perhaps allowing them to be more attentive. In contrast, both the Robinson et al¹⁸ and Kundu et al¹⁷ studies required time out from the participants’ daily schedules. In addition, these studies were notably longer than the Hernandez et al¹⁹ study. The 8-hour intervention in the Chapman et al²⁰ study also may not be feasible for the general population because of its excessive length. However, the intervention was successful among the adolescent participants, which suggested that shorter durations are effective in the adult population and longer interventions may be more appropriate for adolescents because they benefit from peer activity.

Despite the success of the educational interventions as outlined in the 4 studies described here, a major epidemiologic flaw is that these interventions included only a small percentage of the target population. The largest total number of adults surveyed and undergoing an intervention in any of the populations was only 120.¹⁷ By failing to reach a substantial proportion of the population at risk, the number of preventable deaths likely will not decrease. The authors believe a larger-scale intervention would provide meaningful change. Australia’s SunSmart campaign to increase skin cancer awareness in the Australian population is an example of one such large-scale national intervention. The campaign focused on massive television advertisements in the summer to educate participants about the dangers of skin cancer and the importance of protective behaviors. Telephone surveys conducted from 1987 to 2011 demonstrated that more exposure to the advertisements in the SunSmart campaign meant that individuals were more likely to use sunscreen and avoid sun exposure.²² In the United States, a similar intervention would be of great benefit in educating SOC populations regarding skin cancer risk. Additionally, dermatology residents need to be adequately trained to educate patients of color about the risk for skin cancer, as survey data indicated more than 80% of Australian dermatologists desired more SOC teaching during their training and 50% indicated that they would have time to learn it during their training if offered.²³ Furthermore, one study suggested that future interventions must include primary-, secondary-, and tertiary-prevention methods to effectively reduce skin cancer risk among patients of color.²⁴ Primary prevention involves sun avoidance, secondary prevention involves detecting cancerous lesions, and tertiary prevention involves undergoing treatment of skin malignancies. However, increased knowledge does not necessarily mean increased preventative action will be employed (eg, sunscreen use, wearing sun-protective clothing and sunglasses, avoiding tanning beds and excessive sun exposure). Additional studies that demonstrate a notable increase in sun-protective behaviors related to increased knowledge are needed.

Because retention of skin cancer knowledge decreased in several postintervention surveys, there also is a dire need for continuing skin cancer education in patients of color, which may be accomplished through a combination effort of television advertisement campaigns, pamphlets, social media, community health departments, or even community members. For example, a pilot program found that Hispanic lay health workers who are educated about skin cancer may serve as a bridge between medical providers and the Hispanic community by encouraging individuals in this population to get regular skin examinations from a physician.²⁵ Overall, there are currently gaps in the understanding and treatment of skin cancer in people of color.²⁶ Identifying the advantages and disadvantages of all relevant skin cancer interventions conducted in the SOC population will hopefully guide future studies to help close these gaps by allowing others to design the best possible intervention. By doing so, researchers can generate an intervention that is precise, well-informed, and effective in decreasing mortality rates from skin cancer among SOC populations.

Conclusion

All of the studies reviewed demonstrated that instructional and educational interventions are promising methods for improving either knowledge, awareness, or safe skin practices and sun-protective behaviors in SOC populations to differing degrees (Table). Although each of the 4 interventions employed their own methods, they all increased 1 or more of the 3 aforementioned concepts—knowledge, awareness, or safe skin practices and sun-protective behaviors—when comparing postsurvey to presurvey data. However, the critically important message derived from this research is that there is a tremendous need for a substantial large-scale educational intervention to increase knowledge regarding skin cancer in SOC populations.

Malignant melanoma, basal cell carcinoma, and squamous cell carcinoma account for approximately 40% of all neoplasms among the white population in the United States. Skin cancer is the most common malignancy in the United States.¹ However, despite this occurrence, there are limited data regarding skin cancer in individuals with skin of color (SOC). The 5-year survival rates for melanoma are 58.2% for black individuals, 69.7% for Hispanics, and 70.9% for Asians compared to 79.8% for white individuals in the United States.² Even though SOC populations have lower incidences of skin cancer—melanoma, basal cell carcinoma, and squamous cell carcinoma—they exhibit higher death rates.^3-7 Nonetheless, no specific guidelines exist to address sun exposure and safety habits in SOC populations.^6,8 Furthermore, current demographics suggest that by the year 2050, approximately half of the US population will be nonwhite.⁴ Paradoxically, despite having increased sun protection from greater amounts of melanin in their skin, black individuals are more likely to present with advanced-stage melanoma (eg, stage III/IV) compared to white individuals.^8-12 Furthermore, those of nonwhite populations are more likely to present with more advanced stages of acral lentiginous melanomas than white individuals.^13,14 Hispanics also face an increasing incidence of more invasive acral lentiginous melanomas.¹⁵ Overall, SOC patients have the poorest skin cancer prognosis, and the data suggest that the reason for this paradox is delayed diagnosis.¹

Although skin cancer is largely a preventable condition, the literature suggests that lack of awareness of melanoma among ethnic minorities is one of the main reasons for their poor skin cancer prognosis.¹⁶ This lack of awareness decreases the likelihood that an SOC patient would be alert to early detection of cancerous changes.¹⁷ Because educating at-risk SOC populations is key to decreasing skin cancer risk, this study focused on determining the efficacy of major knowledge-based interventions conducted to date.¹ Overall, we sought to answer the question, do knowledge-based interventions increase skin cancer awareness, knowledge, and protective behavior among people of color?

Methods

For this review, the Cochrane method of analysis was used to conduct a thorough search of PubMed articles indexed for MEDLINE (1994-2016), as well as a search of CINAHL (1997-2016), PsycINFO (1999-2016), and Web of Science (1965-2016), using a combination of more than 100 search terms including but not limited to skin cancer, skin of color, intervention, and ethnic skin. The search yielded a total of 52 articles (Figure). Following review, only 8 articles met inclusion criteria, which were as follows: (1) study was related to skin cancer in SOC patients, which included an intervention to increase skin cancer awareness and knowledge; (2) study included adult participants or adolescents aged 12 to 18 years; (3) study was written in English; and (4) study was published in a peer-reviewed journal. Of the remaining 8 articles, 4 were excluded due to the following criteria: (1) study failed to provide both preintervention and postintervention data, (2) study failed to provide quantitative data, and (3) study included participants who worked as health care professionals or ancillary staff. As a result, a total of 4 articles were analyzed and discussed in this review (Table).

Results

Robinson et al¹⁸ conducted 12 focus groups with 120 total participants (40 black, 40 Asian, and 40 Hispanic patients). Participants engaged in a 2-hour tape-recorded focus group with a moderator guide on melanoma and skin cancer. Furthermore, they also were asked to assess skin cancer risk in 5 celebrities with different skin tones. The statistically significant preintervention results of the study (χ²=4.6, P<.001) were as follows: only 2%, 4%, and 14% correctly reported that celebrities with a very fair skin type, a fair skin type, and very dark skin type, respectively, could get sunburn, compared to 75%, 76%, and 62% post-intervention. Additionally, prior to intervention, 14% of the study population believed that dark brown skin type could get sunburn compared to 62% of the same group postintervention. This study demonstrated that the intervention helped SOC patients better identify their ability to get sunburn and identify their skin cancer risk.¹⁸

Hernandez et al¹⁹ used a video-based intervention in a Hispanic community, which was in contrast to the multiracial focus group intervention conducted by Robinson et al.¹⁸ Eighty Hispanic individuals were recruited from beauty salons to participate in the study. Participants watched two 3-minute videos in Spanish and completed a preintervention and postintervention survey. The first video emphasized the photoaging benefits of sun protection, while the second focused on skin cancer prevention. Preintervention surveys indicated that only 54 (68%) participants believed that fair-skinned Hispanics were at risk for skin cancer, which improved to 72 (90%) participants postintervention. Furthermore, initially only 44 (55%) participants thought those with darker skin types could develop skin cancer, but this number increased to 69 (86%) postintervention. For both questions regarding fair and dark skin, the agreement proportion was significantly different between the preeducation and posteducation videos (P<.0002 for the fair skin question and P<.0001 for the dark skin question). This study greatly increased awareness of skin cancer risk among Hispanics,¹⁹ similar to the Robinson et al¹⁸ study.

In contrast to 2-hour focus groups or 3-minute video–based interventions, a study by Kundu et al¹⁷ employed a 20-minute educational class-based intervention with both verbal and visual instruction. This study assessed the efficacy of an educational tutorial on improving awareness and early detection of melanoma in SOC individuals. Photographs were used to help participants recognize the ABCDEs of melanoma and to show examples of acral lentiginous melanomas in white individuals. A total of 71 participants completed a preintervention questionnaire, participated in a 20-minute class, and completed a postintervention questionnaire immediately after and 3 months following the class. The study population included 44 black, 15 Asian, 10 Hispanic, and 2 multiethnic participants. Knowledge that melanoma is a skin cancer increased from 83.9% to 100% immediately postintervention (P=.0001) and 97.2% at 3 months postintervention (P=.0075). Additionally, knowledge that people of color are at risk for melanoma increased from 48.4% preintervention to 82.8% immediately postintervention (P<.0001). However, only 40.8% of participants retained this knowledge at 3 months postintervention. Because only 1 participant reported a family history of skin cancer, the authors hypothesized that the reason for this loss of knowledge was that most participants were not personally affected by friends or family members with melanoma. A future study with an appropriate control group would be needed to support this claim. This study shed light on the potential of class-based interventions to increase both awareness and knowledge of skin cancer in SOC populations.¹⁷

A study by Chapman et al²⁰ examined the effects of a sun protection educational program on increasing awareness of skin cancer in Hispanic and black middle school students in southern Los Angeles, California. It was the only study we reviewed that focused primarily on adolescents. Furthermore, it included the largest sample size (N=148) analyzed here. Students were given a preintervention questionnaire to evaluate their awareness of skin cancer and current sun-protection practices. Based on these results, the investigators devised a set of learning goals and incorporated them into an educational pamphlet. The intervention, called “Skin Teaching Day,” was a 1-day program discussing skin cancer and the importance of sun protection. Prior to the intervention, 68% of participants reported that they used sunscreen. Three months after completing the program, 80% of participants reported sunscreen use, an increase of 12% prior to the intervention. The results of this study demonstrated the unique effectiveness and potential of pamphlets in increasing sunscreen use.²⁰

Comment

Overall, various methods of interventions such as focus groups, videos, pamphlets, and lectures improved knowledge of skin cancer risk and sun-protection behaviors in SOC populations. Furthermore, the unique differences of each study provided important insights into the successful design of an intervention.

An important characteristic of the Robinson et al¹⁸ study was the addition of photographs, which allowed participants not only to visualize different skin tones but also provided them with the opportunity to relate themselves to the photographs; by doing so, participants could effectively pick out the skin tone that best suited them. Written SOC scales are limited to mere descriptions and thus make it more difficult for participants to accurately identify the tone that best fits them. Kundu et al¹⁷ used photographs to teach skin self-examination and ABCDEs for detection of melanoma. Additionally, both studies used photographs to demonstrate examples of skin cancer.^17,18 Recent evidence suggests the use of visuals can be efficacious for improving skin cancer knowledge and awareness; a study in 16 SOC kidney transplant recipients found that the addition of photographs of squamous cell carcinoma in various skin tones to a sun-protection educational pamphlet was more effective than the original pamphlet without photographs.²¹

In contrast to the Robinson et al¹⁸ study and Hernandez et al¹⁹ study, the Kundu et al¹⁷ study showed photographs of acral lentiginous melanomas in white patients rather than SOC patients. However, SOC populations may be less likely to relate to or identify skin changes in skin types that are different from their own. This technique was still beneficial, as acral lentiginous melanoma is the most common type of melanoma in SOC populations. Another benefit of the study was that it was the only study reviewed that included a follow-up postintervention questionnaire. Such data is useful, as it demonstrates how muchinformation is retained by participants and may be more likely to predict compliance with skin cancer protective behaviors.¹⁷

The Hernandez et al¹⁹ study is unique in that it was the only one to include an educational intervention entirely in Spanish, which is important to consider, as language may be a hindrance to participants’ understanding in the other studies, particularly Hispanics, possibly leading to a lack of information retention regarding sun-protective behaviors. Furthermore, it also was the only study to utilize videos as a method for interventions. The 3-minute videos demonstrated that interventions could be efficient as compared to the 2-hour in-class intervention used by Robinson et al¹⁸ and the 20-minute intervention used by Kundu et al.¹⁷ Additionally, videos also could be more cost-effective, as incentives for large focus groups would no longer be needed. Furthermore, in the Hernandez et al¹⁹ study, there was minimal to no disruption in the participants’ daily routine, as the participants were getting cosmetic services while watching the videos, perhaps allowing them to be more attentive. In contrast, both the Robinson et al¹⁸ and Kundu et al¹⁷ studies required time out from the participants’ daily schedules. In addition, these studies were notably longer than the Hernandez et al¹⁹ study. The 8-hour intervention in the Chapman et al²⁰ study also may not be feasible for the general population because of its excessive length. However, the intervention was successful among the adolescent participants, which suggested that shorter durations are effective in the adult population and longer interventions may be more appropriate for adolescents because they benefit from peer activity.

Despite the success of the educational interventions as outlined in the 4 studies described here, a major epidemiologic flaw is that these interventions included only a small percentage of the target population. The largest total number of adults surveyed and undergoing an intervention in any of the populations was only 120.¹⁷ By failing to reach a substantial proportion of the population at risk, the number of preventable deaths likely will not decrease. The authors believe a larger-scale intervention would provide meaningful change. Australia’s SunSmart campaign to increase skin cancer awareness in the Australian population is an example of one such large-scale national intervention. The campaign focused on massive television advertisements in the summer to educate participants about the dangers of skin cancer and the importance of protective behaviors. Telephone surveys conducted from 1987 to 2011 demonstrated that more exposure to the advertisements in the SunSmart campaign meant that individuals were more likely to use sunscreen and avoid sun exposure.²² In the United States, a similar intervention would be of great benefit in educating SOC populations regarding skin cancer risk. Additionally, dermatology residents need to be adequately trained to educate patients of color about the risk for skin cancer, as survey data indicated more than 80% of Australian dermatologists desired more SOC teaching during their training and 50% indicated that they would have time to learn it during their training if offered.²³ Furthermore, one study suggested that future interventions must include primary-, secondary-, and tertiary-prevention methods to effectively reduce skin cancer risk among patients of color.²⁴ Primary prevention involves sun avoidance, secondary prevention involves detecting cancerous lesions, and tertiary prevention involves undergoing treatment of skin malignancies. However, increased knowledge does not necessarily mean increased preventative action will be employed (eg, sunscreen use, wearing sun-protective clothing and sunglasses, avoiding tanning beds and excessive sun exposure). Additional studies that demonstrate a notable increase in sun-protective behaviors related to increased knowledge are needed.

Because retention of skin cancer knowledge decreased in several postintervention surveys, there also is a dire need for continuing skin cancer education in patients of color, which may be accomplished through a combination effort of television advertisement campaigns, pamphlets, social media, community health departments, or even community members. For example, a pilot program found that Hispanic lay health workers who are educated about skin cancer may serve as a bridge between medical providers and the Hispanic community by encouraging individuals in this population to get regular skin examinations from a physician.²⁵ Overall, there are currently gaps in the understanding and treatment of skin cancer in people of color.²⁶ Identifying the advantages and disadvantages of all relevant skin cancer interventions conducted in the SOC population will hopefully guide future studies to help close these gaps by allowing others to design the best possible intervention. By doing so, researchers can generate an intervention that is precise, well-informed, and effective in decreasing mortality rates from skin cancer among SOC populations.
