Skin in the game: The cost consequences of skin cancer diagnosis, treatment and care in Northern Ireland

BACKGROUND

Skin cancer is a prevalent cancer in the UK. Its rising incidence and mortality rates are expected to result in substantial financial implications, particularly on diagnostic and treatment services for skin cancer management in Northern Ireland (NI). Such anticipated disease increases underscore the need for prevention and control measures that should help guide policymaking and planning efforts.

METHODS

We conducted a cost of illness study to assess the economic impact of skin cancer in NI from the healthcare system's perspective, using a bottom-up method, employing NHS reference costs (UK£) for skin cancer diagnosis and treatment patient pathways in 2021/22. Sensitivity analyses varied diagnostic volumes by applying multipliers for benign cases, assuming a diagnostic conversion rate of 6.8%, and examined an alternative chemotherapy regimen compliance rate of 75%. Additionally, proportional cost increases were projected based on future estimated increases of 9% and 28% to malignant melanoma (MM) cases for diagnostic, treatment, and follow-up volumes.

RESULTS

Significant numbers of non-melanoma skin cancers (NMSC) and MM cases were recorded, 4289 NMSCs and 439 MM cases. The total cost for managing NMSC was £ 3,365,350. Total costs for MM skin cancer were £ 13,740,681, including £ 8,753,494 for procurement, administration, and chemotherapy drug use. Overall healthcare spending on skin cancer care totalled £ 21,167,651. Sensitivity analysis suggested diagnostic cost may increase significantly to £ 12,374,478 based on referral volume assumptions. If base case rates rise by 9 or 28% estimated total costs of treating skin cancer will increase to £ 22.3 million and £ 24.9 million, respectively.

CONCLUSIONS

Skin cancer management costs in NI totalled ∼£ 21.1 million to £ 32.1 million, depending on diagnostic referral assumptions. Costs have risen ∼10-fold over the past decade for MM due largely to chemotherapy costs. A predicted 28% increase in MM cases by 2040 would lead to ∼£ 3.8 million of additional expenditures, providing a significant challenge for cancer health systems.

Skin Cancer Prevention across the G7, Australia and New Zealand: A Review of Legislation and Guidelines

Incidence rates of melanoma and keratinocyte skin cancers have been on the rise globally in recent decades. While there has been a select focus on personal sun protection awareness, to our knowledge, there is a paucity of legislation in place to help support citizens' efforts to protect themselves from the harmful effects of ultraviolet radiation (UVR). Given this, we conducted a comprehensive review of legislation and guidelines pertaining to a variety of sun protection-related topics in countries of the Group of Seven (G7), Australia and New Zealand. Australia was the only country to have banned tanning beds for individuals of all ages, while other select countries have instituted bans for minors. In workplace policy, there is very little recognition of the danger of occupational UVR exposure in outdoor workers, and thus very few protective measures are in place. With regard to sports and recreation, certain dermatological/professional associations have put forward recommendations, but no legislation was brought forward by government bodies outside of Australia and New Zealand. With regard to youth, while there are various guidelines and frameworks in place across several countries, adherence remains difficult in the absence of concrete legislation and standardization of procedures. Finally, only Australia and a few select jurisdictions in the United States have implemented sales tax exemptions for sunscreen products. In light of our findings, we have made several recommendations, which we anticipate will help reduce the rates of melanoma and keratinocyte cancers in years to come. However, minimizing UVR exposure is not without risk, and we, therefore, suggest the promotion of vitamin D supplementation in conjunction with sun protective practices to limit potential harm.

Public Health Messaging to Address Indoor Tanning: A Scoping Review

Indoor tanning (IT) is an avoidable skin cancer risk. Although numerous communication interventions have been assessed for IT deterrence, less attention has been paid to the persuasive messages within these interventions. This scoping review summarizes the current peer-reviewed literature on persuasive messages for IT. Overall, 20 articles (21 studies) were included. Most were experimental or quasi-experimental and conducted in the US. Participants were mostly young women who had tanned indoors before. Few studies evaluated persuasive theme; in those that did, health and appearance themes were effective. Narrative and statistical evidence formats were also effective. The included studies also supported normative messages, loss-framed messages, and images. Improved reporting on message design and evaluation would be beneficial for future evidence synthesis. Our understanding of persuasive messages for IT has expanded in recent years, but more research is needed to optimize them.

Reasons for using indoor tanning devices: A systematic review of qualitative evidence

PURPOSE

Despite the established causal links to skin cancer, skin ageing and eye inflammation, people continue to use indoor tanning devices (hereafter 'sunbeds'). Understanding the reasons underlying the use of sunbeds is essential for developing effective interventions. The purpose of this study was to collate all existing evidence from qualitative papers published to date that had assessed motivations for using sunbeds.

METHODS

Six databases were searched from inception to February 2020 for qualitative studies that explored adults' experiences of using sunbeds. Sixteen studies met the inclusion criteria, and a narrative evidence synthesis was used to collate findings from each primary study.

RESULTS

Users of sunbeds were motivated primarily by aesthetic concerns but also by perceived psychological benefits (well-being, confidence and 'fitting in') and physical benefits (improvement in skin conditions such as acne, acquiring vitamin D and preventing sunburn). People also chose indoor tanning over alternatives such as fake tans because they considered the alternatives unacceptable and did not consider indoor tanning a serious health risk. To date, no studies have explored alternatives to meeting non-aesthetic needs related to the use of sunbeds.

CONCLUSIONS

This comprehensive explanation for the practice of indoor tanning provides the basis for development of complex interventions to reduce the harm caused by using sunbeds. Effective interventions should include promotion of alternatives, such as different methods of relaxing, to satisfy underlying motivations, changing social norms and correcting misperceptions about health benefits.

Educational level-dependent melanoma awareness in a high-risk population in Switzerland

Introduction

The worldwide incidence of melanoma has been increasing rapidly in recent decades with Switzerland having one of the highest rates in Europe. Ultraviolet (UV) radiation is one of the main risk factors for skin cancer. Our objective was to investigate UV protective behavior and melanoma awareness in a high-risk cohort for melanoma.

Methods

In this prospective monocentric study, we assessed general melanoma awareness and UV protection habits in at-risk patients (≥100 nevi, ≥5 dysplastic nevi, known CDKN2A mutation, and/or positive family history) and melanoma patients using questionnaires.

Results

Between 01/2021 and 03/ 2022, a total of 269 patients (53.5% at-risk patients, 46.5% melanoma patients) were included. We observed a significant trend toward using a higher sun protection factor (SPF) in melanoma patients compared with at-risk patients (SPF 50+: 48% [n=60] vs. 26% [n=37]; p=0.0016). Those with a college or university degree used a high SPF significantly more often than patients with lower education levels (p=0.0007). However, higher educational levels correlated with increased annual sun exposure (p=0.041). Neither a positive family history for melanoma, nor gender or Fitzpatrick skin type influenced sun protection behavior. An age of ≥ 50 years presented as a significant risk factor for melanoma development with an odd's ratio of 2.32. Study participation resulted in improved sun protection behavior with 51% reporting more frequent sunscreen use after study inclusion.

Discussion

UV protection remains a critical factor in melanoma prevention. We suggest that melanoma awareness should continue to be raised through public skin cancer prevention campaigns with a particular focus on individuals with low levels of education.

An Epidemiological Update on Indoor Tanning and the Risk of Skin Cancers

Indoor tanning (sunbeds, solarium) uses artificial ultraviolet radiation (UVR) to stimulate cosmetic tanning of the skin. Indoor tanning has been officially classified as a human carcinogen in 2009 by the International Agency for Research on Cancer of the World Health Organization (WHO). The differences in the prevalence of sunbed use across countries and over the years highlight underlying legislative, climatic, and cultural differences. Indoor tanning-seeking behaviors may be driven by motivations for an appealing appearance, largely influenced by gender and age, and several misconceptions that a prevacation tan safeguards the skin, that sunbeds can be used to treat acne or to increase vitamin D, or that tanning is a healthy habit. This review provides an epidemiological update on the prevalence of sunbed use, who tends to use sunbeds and why, and details the current evidence on the association of sunbeds with skin cancers, including cutaneous melanoma, basal cell carcinoma (BCC), and cutaneous squamous cell carcinoma (cSCC). A statistically significant higher risk of cutaneous melanoma, BCC and cSCC with the use of sunbeds has been consistently demonstrated. This risk of skin cancer is even higher with the more frequent use of sunbeds, underscoring a dose-response relationship, and in those first exposed to sunbeds at a younger age. Preventive measures against sunbed use include legislation restricting sunbed use, educational campaigns to inform and discourage from indoor tanning, as well as using the internet, online advertising messages and the social media to reach larger audiences and to promote an untanned appearance.
