Efficacy, cost-minimization, and budget impact of a personalized discharge letter for basal cell carcinoma patients to reduce low-value follow-up care.

BACKGROUND: The incidence of keratinocyte carcinomas is high and rapidly growing. Approximately 80% of keratinocyte carcinomas consist of basal cell carcinomas (BCC) with 50% of these being considered as low-risk tumors. Nevertheless, 83% of the low-risk BCC patients were found to receive more follow-up care than recommended according to the Dutch BCC guideline, which is one visit post-treatment for this group. More efficient management could reduce unnecessary follow-up care and related costs. OBJECTIVES: To study the efficacy, cost-utility, and budget impact of a personalized discharge letter for low-risk BCC patients compared with usual care (no personalized letter). METHODS: In a multi-center intervention study, a personalized discharge letter in addition to usual care was compared to usual care in first-time BCC patients. Model-based cost-utility and budget impact analyses were conducted, using individual patient data gathered via surveys. The outcome measures were number of follow-up visits, costs and quality adjusted life years (QALY) per patient. RESULTS: A total of 473 first-time BCC patients were recruited. The personalized discharge letter decreased the number of follow-up visits by 14.8% in the first year. The incremental costs after five years were -€24.45 per patient. The QALYs were 4.12 after five years and very similar in both groups. The national budget impact was -€2,7 million after five years. CONCLUSIONS: The distribution of a personalized discharge letter decreases the number of unnecessary follow-up visits and implementing the intervention in a large eligible population would results in substantial cost savings, contributing to restraining the growing BCC costs.

A Non-Surgical and Cost-Effective Treatment Approach Employing Topical Imiquimod, 5-Fluorouracil, and Tretinoin for Primary Non-Melanoma Skin Cancers.

BACKGROUND: Minimally invasive alternative approaches to treat non-melanoma skin cancers remain limited and unproven. OBJECTIVE: We aim to assess the efficacy of varying combinations of anti-tumor agents—imiquimod 5% cream, 5-fluorouracil 2% solution, and tretinoin 0.1% cream—with brief cryotherapy in treating non-melanoma skin cancers. METHODS: This retrospective study included 690 cases of non-melanoma skin cancers in 480 patients who received a diagnosis of a basal cell carcinoma or squamous cell carcinoma during a ten-year period. During treatment period, patients applied 30 applications of one of three combinations (imiquimod/tretinoin, 5-fluorouracil/tretinoin, or imiquimod/5-fluorouracil/tretinoin) and had cryotherapy every 2 weeks. Each patient had a clinical examination at least three years post-treatment or documented treatment failure. Clearance was defined by a lack of persistence or recurrence for 3 years following the completion of treatment. The likelihood of lesion clearance was evaluated using multivariable logistic regression analysis. RESULTS: A total of 186 cases (97; basal cell carcinoma and 89; squamous cell carcinoma) in 133 patients [37% women and 63% men; median (interquartile range) age, 77 (69, 83) years] met the inclusion criteria. Multivariable logistic regression analysis adjusting for clinical and lesion variables demonstrated that, relative to the imiquimod/5-fluorouracil/tretinoin treatment approach, imiquimod/ tretinoin (odds ratio, 0.05; 95% confidence interval, 0.00-0.99) and 5-fluorouracil/tretinoin (0.02; 0.00–0.45) were associated with lower likelihoods of lesion clearance. Likewise, morpheaform basal cell carcinoma had a lower probability of clearance (0.05; 0.00–0.72). CONCLUSIONS: The combination of imiquimod/5-fluorouracil/tretinoin with cryotherapy had high clearance rates and was the most effective treatment regimen.

Treatment of cutaneous basal cell carcinoma with combined laser extirpation and methyl aminolevulinic acid: five-year success rates.

INTRODUCTION: Basal cell carcinoma is the most common cancer. Excisional surgery is associated with a high clearance rate, at the expense of significant functional and aesthetic morbidity, especially within the T-zone or for extensive lesions. We report five-year follow-up outcomes for carbon dioxide laser extirpation of cutaneous basal cell carcinoma, assisted by immediate methyl aminolevulinate photodynamic therapy and cost-benefit considerations. MATERIALS AND METHODS: Retrospective cohort database analysis of adult patients with biopsy-proven primary cutaneous basal cell carcinoma, completing five years of follow-up. Direct per-lesion cost was compared with conventional wide local excision. Patients with morphoeic basal cell carcinoma were excluded. RESULTS: Treated lesions were up to 1% total body surface area and up to 3.8mm (1.38 ± 0.695cm, mean ± standard deviation) in biopsy-proven depth. At the five-year follow-up mark, 93.6% of treated areas remained free of recurrence. Nodular basal cell carcinoma was the most common subtype (41.5%). A mean tumour depth greater than 2 ± 0.872mm was significantly associated with recurrence (Mann-Whitney, p = 0.0487). For a service delivered through the NHS at 2015 prices, we report a 43% saving, equating to a saving of £235 per basal cell carcinoma or a national annualised saving of £70 million by 2025 for the NHS. CONCLUSION: Our results suggest that CO2-assisted photodynamic therapy is non-inferior to excision but may offer better functional and cosmetic preservation at a fraction of the direct like for like cost of operative surgery. Investigation of this method by randomised controlled methodology is warranted.

Willingness to Pay for Surgical Treatments for Basal Cell Carcinoma: A Population-Based Cross-Sectional Study.

BACKGROUND: Keratinocyte carcinoma (KC) treatment accounts for approximately $5 billion in spending per year, yet no studies have evaluated the US general public's willingness to pay (WTP) for these procedures. OBJECTIVE: To determine the monetary value of surgical KC treatments, as perceived by society, as a measure of preference. PARTICIPANTS, METHODS AND MATERIALS: We performed an internet-based age-, sex-, and race-stratified cross-sectional survey of 425 subjects representative of the US general population. Stated WTP and desirability of electrodesiccation and curettage (EDC), excision, and Mohs micrographic surgery (MMS) for facial and extrafacial basal cell carcinoma (BCC) were assessed. A discrete choice experiment was performed using maximum likelihood estimation, and a secondary analysis was performed to determine the influence of framing MMS as the best treatment option. RESULTS: A total of 425 subjects finished their questionnaires, yielding a completion rate of 97%. Median (interquartile range) stated WTP for EDC, excision, and MMS were $1,000 (421-2,079), $1,503 (562-3,062), and $3,006 (1,250-5,084), respectively, when MMS was framed in a standard fashion. Stated WTP for MMS increased to $3,989 (2,015-5,801) when it was framed as the best option. For BCC on the back, WTP for MMS dropped by 12%. CONCLUSION: There is markedly higher societal WTP for MMS on both the face and trunk, regardless of whether MMS is framed as the best option. Gold-standard bias may affect WTP and desirability in medical decision-making under uncertainty, inflating the WTP of options framed as the best while decreasing the desirability of alternatives.

Keratinocyte cancer excisions in Australia: Who performs them and associated costs.

BACKGROUND/OBJECTIVE: To describe the clinical settings in which keratinocyte cancers are excised in Queensland and describe the types of practitioners who excise them; to examine costs; and to identify predictors of hospital admission. METHODS: We used linked data for participants from the QSkin study (n = 43 794), including Medicare claims and Queensland hospital admissions relating to treatment episodes for incident keratinocyte cancers from July 2011 to June 2015. We used multinomial logistic regression to measure associations between demographic and clinical characteristics and treatment setting. The median costs of Medicare claims (AU$) were calculated. RESULTS: During 4 years of follow-up, there were 18 479 skin cancer excision episodes among 8613 people. Most excisions took place in private clinical rooms (89.7%), the remainder in hospitals (7.9% private; 2.4% public). Compared with other anatomical sites, skin cancers on the nose, eyelid, ear, lip, finger or genitalia were more likely to be treated in hospitals than in private clinical rooms (public hospital OR 5.7; 95%CI 4.5-7.2; private hospital OR 8.3; 95%CI 7.3-9.4). Primary care practitioners excised 83% of keratinocyte cancers, followed by plastic surgeons (9%) and dermatologists (6%). The median Medicare benefit paid was $253 in private clinical rooms and $334 in private hospitals. Out-of-pocket payments by patients treated in private hospitals were fourfold higher than those in private clinical rooms ($351 vs $80). CONCLUSIONS: Most keratinocyte cancers are excised in primary care, although more than 10% of excisions occur in hospital settings.

The economic burden of occupational non-melanoma skin cancer due to solar radiation.

Solar ultraviolet (UV) radiation is the second most prevalent carcinogenic exposure in Canada and is similarly important in other countries with large Caucasian populations. The objective of this article was to estimate the economic burden associated with newly diagnosed non-melanoma skin cancers (NMSCs) attributable to occupational solar radiation exposure. Key cost categories considered were direct costs (healthcare costs, out-of-pocket costs (OOPCs), and informal caregiver costs); indirect costs (productivity/output costs and home production costs); and intangible costs (monetary value of the loss of health-related quality of life (HRQoL)). To generate the burden estimates, we used secondary data from multiple sources applied to computational methods developed from an extensive review of the literature. An estimated 2,846 (5.3%) of the 53,696 newly diagnosed cases of basal cell carcinoma (BCC) and 1,710 (9.2%) of the 18,549 newly diagnosed cases of squamous cell carcinoma (SCC) in 2011 in Canada were attributable to occupational solar radiation exposure. The combined total for direct and indirect costs of occupational NMSC cases is $28.9 million ($15.9 million for BCC and $13.0 million for SCC), and for intangible costs is $5.7 million ($0.6 million for BCC and $5.1 million for SCC). On a per-case basis, the total costs are $5,670 for BCC and $10,555 for SCC. The higher per-case cost for SCC is largely a result of a lower survival rate, and hence higher indirect and intangible costs. Our estimates can be used to raise awareness of occupational solar UV exposure as an important causal factor in NMSCs and can highlight the importance of occupational BCC and SCC among other occupational cancers.

Impact of topical fluorouracil cream on costs of treating keratinocyte carcinoma (nonmelanoma skin cancer) and actinic keratosis.

BACKGROUND: It is unknown whether treatment costs for keratinocyte carcinoma (KC) and actinic keratosis (AK) can be lowered by spending more on chemoprevention. OBJECTIVE: To examine the impact of 1-course treatment with topical fluorouracil (5-FU) on the face and ears on KC and AK treatment costs over 3 years. METHODS: The Veterans Affairs Keratinocyte Carcinoma Chemoprevention trial compared the efficacy of topical 5-FU 5% with that of vehicle control cream for reducing KC risk. Trial data and administrative data on costs and utilization were analyzed to measure postrandomization encounters and treatment costs for KC and AK care. Adjusted models were used to test for statistically significant differences between treatment arms for number of treatment encounters and costs. RESULTS: One year after randomization, the control arm had a higher mean number of treatment encounters for squamous cell carcinoma (0.04) than the intervention arm (0.01) (P < .01). At 1 year, the intervention arm had lower treatment and dermatologic costs: $2106 (standard deviation, $2079) compared with $2444 (standard deviation, $2716) for the control patients (P = .02). After 3 years, the intervention arm incurred a cost of $771 less per patient. LIMITATIONS: Care not provided or paid for by the Department of Veterans Affairs was not included. Results may not be generalizable to other payers. CONCLUSION: We found significant cost savings for patients treated with 5-FU.

Cost-Effectiveness Analysis of a Skin Awareness Intervention for Early Detection of Skin Cancer Targeting Men Older Than 50 Years.

OBJECTIVES: To assess the cost-effectiveness of an educational intervention encouraging self-skin examinations for early detection of skin cancers among men older than 50 years. METHODS: A lifetime Markov model was constructed to combine data from the Skin Awareness Trial and other published sources. The model incorporated a health system perspective and the cost and health outcomes for melanoma, squamous and basal cell carcinomas, and benign skin lesions. Key model outcomes included Australian costs (2015), quality-adjusted life-years (QALYs), life-years, and counts of skin cancers. Univariate and probabilistic sensitivity analyses were undertaken to address parameter uncertainty. RESULTS: The mean cost of the intervention was A$5,298 compared with A$4,684 for usual care, whereas mean QALYs were 7.58 for the intervention group and 7.77 for the usual care group. The intervention was thus inferior to usual care. When only survival gain is considered, the model predicted the intervention would cost A$1,059 per life-year saved. The likelihood that the intervention was cost-effective up to A$50,000 per QALY gained was 43.9%. The model was stable to most data estimates; nevertheless, it relies on the specificity of clinical diagnosis of skin cancers and is subject to limited health utility data for people with skin lesions. CONCLUSIONS: Although the intervention improved skin checking behaviors and encouraged men to seek medical advice about suspicious lesions, the overall costs and effects from also detecting more squamous and basal cell carcinomas and benign lesions outweighed the positive health gains from detecting more thin melanomas.
