The importance of patient-centred care to overcome barriers in the management of actinic keratosis

The "Personalising Actinic Keratosis Treatment for Immunocompromised Patients" (IM-PAKT) Project: An Expert Panel Opinion

Actinic keratosis (AK) is an intraepithelial condition characterized by the development of scaly, erythematous lesions after repeated exposure to ultraviolet radiation. Significant immunosuppression is a risk factor for the development of AK and subsequent lesion progression to squamous cell carcinoma. Immunocompromised patients (ICPs), particularly organ transplant recipients, often have more advanced or complex AK presentations and an increased risk of skin carcinomas versus non-ICPs with AK, making lesions more difficult to treat and resulting in worse treatment outcomes. The recent "Personalising Actinic Keratosis Treatment" (PAKT) consensus reported that delivering patient-centric care may play a role in supporting better clinical outcomes and patient satisfaction with treatments for chronic dermatologic conditions such as AK, which require repeated cycles of treatment. Additionally, currently published guidance and recommendations were considered by the PAKT panel to be overly broad for managing ICPs with their unique and complex needs. Therefore, the "Personalising Actinic Keratosis Treatment for Immunocompromised Patients" (IM-PAKT) panel was established to build upon general recommendations from the PAKT consensus. The panel identified current gaps in guidance for AK care in ICPs, offered practical care approaches based on typical ICP scenarios, and highlighted the need to adapt AK management to optimize care and improve treatment outcomes in ICPs. In particular, dermatologists should establish collaborative and transparent relationships with patients' multidisciplinary teams to enhance overall care for patients' comorbidities: given their increased risk of progression to malignancy, earlier assessments/interventions and frequent follow-ups are vital.The panel also developed a novel "triage" tool outlining effective treatment follow-up and disease surveillance plans tailored to patients' risk profiles, guided by current clinical presentation and relevant medical history. Additionally, we present the panel's expert opinion on three fictional ICP scenarios to explain their decision-making process for assessing and managing typical ICPs that they may encounter in clinical practice.

Refusal of Retreatment With Topical 5-Fluorouracil Among Patients With Actinic Keratosis: Qualitative Analysis

BACKGROUND

Actinic keratosis (AK) is a common premalignant skin lesion, and topical 5-fluorouracil (5-FU) is commonly used in field-directed therapy. However, 5-FU is associated with frequent local skin reactions.

OBJECTIVE

This study aimed to qualitatively assess experiences among patients with AK who refuse retreatment with 5-FU.

METHODS

Semistructured interviews were conducted with 10 adult participants who had received treatment with 5-FU for AK between January 1, 2017, and January 1, 2020, and refused future treatment with 5-FU. Results were analyzed using qualitative research methods.

RESULTS

Although most participants had low concern upon having received a diagnosis of AK, most felt that treatment is very important. When initiating treatment with 5-FU, most cited recommendation by their health care professionals as the primary motivator and initially had low concern regarding treatment. The side effects associated with treatment were physically and psychosocially burdensome for most participants and led to temporary lifestyle adjustments. After treatment, most did not believe that their health care provider prepared them for treatment or were unsure. While half of the participants felt that 5-FU helped treat AKs, half were either unsure, due to premature discontinuation, or did not think that 5-FU treated their AKs.

CONCLUSIONS

5-FU is one of the most commonly prescribed treatments for AKs, yet most patients experienced both a physical and psychosocial burden with the treatment. Inability to assess efficacy due to premature discontinuation secondary to 5-FU-related reactions is common, and shared decision-making, navigating treatment options, and taking into account patient preferences may be critical to help assure better adherence and outcomes. Although our study was limited by input from participants who refused future treatment with 5-FU, most stated that they would still continue to seek treatment for AKs in the future and would consider other topical treatments, especially if associated with a milder tolerability profile.

Actinic Keratoses (AK): An Exploratory Questionnaire-Based Study of Patients’ Illness Perceptions

Simple Summary

We recorded 208 patients receiving treatment for AK and conducted a cross-sectional questionnaire-based study, which aimed to investigate patients’ perceptions of their illness. Our main objective was the detection not only of the illness perception of AK patients, but also of its influence on their perception of treatment and the correlation with patients’ demographic characteristics and history, as well as the readiness to use sunscreen. The rising incidence of AK and its socioeconomic burden place the illness perception of AK patients among the most important barriers to overcome for the effective management of the disease. To the best of our knowledge, this is one of the first studies to attempt to unveil the illness perceptions of AK patients and their correlation with patients’ demographics and sunscreen use and the influence on AK treatment. We strongly support reinforcing the awareness of AK and the role of dermatologists is crucial for this direction.

Abstract

Background: Decreased illness perception among actinic keratoses (AK) patients is a major barrier to the effective management of AK. Objective: We aimed to investigate patients’ illness and treatment perceptions, their correlation to demographics and AK/skin cancer history, and secondarily the influence of these perspectives on treatment and sunscreen use. Materials and Methods: Participants completed questionnaires based on the Brief Illness Perception Questionnaire and statistical analysis was performed. Results: In total, 208 AK patients were enrolled. A large proportion were poorly aware of the disease (41.4%), with less than half (43%) being familiar with AK. Patients were aware of the chronic nature of the disease and its correlation to sunlight regardless of demographic characteristics. The level of education played a role in disease awareness (p = 0.006), and treatment plan perception (p = 0.002). The increase in sunscreen protection after AK diagnosis was higher in women (p = 0.009) and younger patients (p = 0.044). Patients’ concerns regarding treatment were mainly related to the duration (30%) and effectivity (25%). Dermatologists’ statements highlighting that AK are precancerous lesions (86.2%) influenced patients’ willingness for treatment. Conclusion: Improved awareness of AK is necessary to increase treatment seeking and compliance, regarding both treatment and sunscreen use. Dermatologists’ statements may have critical influence on patients’ decisions to receive treatment for AK.

A Review of Existing Therapies for Actinic Keratosis: Current Status and Future Directions

Actinic keratosis (AK) is a chronic skin disease in which clinical and subclinical cutaneous lesions coexist on sun-exposed areas such as the head and neck region and the extremities. The high prevalence of AK means the disease burden is substantial, especially in middle-aged and elderly populations. Evidence indicates that AK may progress into invasive cutaneous squamous cell carcinoma, so the European guidelines recommend treatment of any AK regardless of clinical severity. Given the aging population and therefore the increasing incidence of AK and cutaneous field carcinogenesis, further updates on the long-term efficacy of current therapies and new investigational agents are critical to guide treatment choice. Patients often have difficulty adequately applying topical treatments and coping with adverse local skin reactions, leading to less than optimum treatment adherence. The development of associated local skin symptoms and cosmetic outcomes for the area of interest are also relevant to the choice of an appropriate therapeutic strategy. Treatment is always individually tailored according to the characteristics of both patients and lesions. This review focuses on the therapeutic approaches to AK and illustrates the currently available home-based and physician-managed treatments.

Guidelines of care for the management of actinic keratosis

BACKGROUND

Actinic keratoses (AK) are rough scaly patches that arise on chronically ultraviolet-exposed skin and can progress to keratinocyte carcinoma.

OBJECTIVE

This analysis examined the literature related to the management of AK to provide evidence-based recommendations for treatment. Grading, histologic classification, natural history, risk of progression, and dermatologic surveillance of AKs are also discussed.

METHODS

A multidisciplinary Work Group conducted a systematic review to address 5 clinical questions on the management of AKs and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of the evidence and formulating and grading clinical recommendations. Graded recommendations were voted on to achieve consensus.

RESULTS

Analysis of the evidence resulted in 18 recommendations.

LIMITATIONS

This analysis is based on the best available evidence at the time it was conducted. The pragmatic decision to limit the literature review to English language randomized trials may have excluded data published in other languages or limited identification of relevant long-term follow-up data.

CONCLUSIONS

Strong recommendations are made for using ultraviolet protection, topical imiquimod, topical 5-fluorouracil, and cryosurgery. Conditional recommendations are made for the use of photodynamic therapy and diclofenac for the treatment of AK, both individually and as part of combination therapy regimens.

Patient-reported outcomes of topical therapies in actinic keratosis: A systematic review

Patients' perspectives on actinic keratosis treatments may have an impact on treatment adherence and, therefore, therapeutic outcomes. We performed a systematic review to assess patients' perspectives of topical, field‐directed treatments for actinic keratoses. A literature search was conducted, and 14 studies were identified encompassing 4433 patients. Only four studies were focused on face and/or scalp, which are the locations that typically impact patients' quality of life. Four studies were clinical trials. One study utilized a validated patient‐reported outcomes (PRO) instrument specifically developed for actinic keratosis. In general, treatment adherence and patient satisfaction were better with shorter‐duration treatment regimens such as ingenol mebutate gel. Imiquimod improved quality of life in one study but not in another. No data was available on topical piroxicam. The findings underscore the need for effective and well‐tolerated, short‐duration topical treatment for actinic keratosis.

Treatment Motivations and Expectations in Patients with Actinic Keratosis: A German-Wide Multicenter, Cross-Sectional Trial

Patient-centered motives and expectations of the treatment of actinic keratoses (AK) have received little attention until now. Hence, we aimed to profile and cluster treatment motivations and expectations among patients with AK in a nationwide multicenter, cross-sectional study including patients from 14 German skin cancer centers. Patients were asked to complete a self-administered questionnaire. Treatment motives and expectations towards AK management were measured on a visual analogue scale from 1-10. Specific patient profiles were investigated with subgroup and correlation analysis. Overall, 403 patients were included. The highest motivation values were obtained for the items "avoid transition to invasive squamous cell carcinoma" (mean ± standard deviation; 8.98 ± 1.46), "AK are considered precancerous lesions" (8.72 ± 1.34) and "treating physician recommends treatment" (8.10 ± 2.37; p < 0.0001). The highest expectation values were observed for the items "effective lesion clearance" (8.36 ± 1.99), "safety" (8.20 ± 2.03) and "treatment-related costs are covered by health insurance" (8.00 ± 2.41; p < 0.0001). Patients aged ≥77 years and those with ≥7 lesions were identified at high risk of not undergoing any treatment due to intrinsic and extrinsic motivation deficits. Heat mapping of correlation analysis revealed four clusters with distinct motivation and expectation profiles. This study provides a patient-based heuristic tool for a personalized treatment decision in patients with AK.

Physician-patient communication and patient-reported outcomes in the actinic keratosis treatment adherence initiative (AK-TRAIN): a multicenter, prospective, real-life study of treatment satisfaction, quality of life and adherence to topical field-directed therapy for the treatment of actinic keratosis in Italy

BACKGROUND

Patients with multiple actinic keratoses (AKs) should be treated with field-directed therapy. Such treatments challenge patients' adherence due to out-of-pocket costs, length of treatment and severity of local skin reactions (LSRs). Effective physician-patient communication (PPC) may buffer therapy-related distress, thus improving quality of life, treatment satisfaction and adherence.

OBJECTIVES

We evaluated the interplay between PPC, LSR intensity (safety) and lesion clearance rates (effectiveness) on treatment satisfaction, quality of life and treatment adherence among patients with multiple AKs receiving topical field-directed therapies.

METHODS

In this observational, multicentre, longitudinal, cohort study, we included 1136 adult patients with discrete, clinically detectable, visible, multiple (three or more lesions in a 25 cm² area), Grade I/II AKs, for whom the attending dermatologist has prescribed treatment with a topical field-directed therapy. We matched self-reported data and medical information recorded by dermatologists in standard clinical forms. Patients were followed up at two time points (T1: 8 days; T2: 25-30 days) RESULTS: Most patients were elderly, married, men with poor socio-economic status and multiple lesions of the scalp or face. The majority (n = 961) had a prescription of ingenol mebutate (IMB) and 175 received either diclofenac 3% in hyaluronic acid (DHA) or imiquimod 5% (IMQ). Clearance rate at 1 month was 84%. Most patients felt very supported (n = 819, 73%) and rated dermatologist's explanations very clear (n = 608, 54%). Treatment satisfaction (effectiveness and convenience scales) increased along the follow-up, especially for those on IMB (Δ_pre-post  = -4.00; other: Δ_pre-post  = -0.25; interaction P < 0.001). Communication clarity was associated with higher treatment satisfaction scores (β = 0.4-0.6, P < 0.01) and lower risk of non-adherence among IMB patients (risk difference: 16%, P < 0.01).

CONCLUSION

Communication clarity was associated with patient-reported outcomes and adherence beyond AK-related clinical parameters. Our study questions the current episodic approach to AK management and provides the rationale to develop chronic care models fostering patients' engagement and treatment alliance.

Swiss (German) Version of the Actinic Keratosis Quality of Life questionnaire

BACKGROUND

Actinic keratosis (AK) is a sun-induced skin lesion that may progress to invasive squamous cell carcinoma of the skin. Recently, the Actinic Keratosis Quality of Life questionnaire (AKQoL) was designed for patients with AK in Denmark as a specific quality of life instrument for AK patients.

OBJECTIVE

The objective of this study was to adapt the AKQoL for the German language region of Switzerland and to evaluate its psychometric properties (validity, reliability).

METHODS

Translation and cultural adaptation of the questionnaire were assessed by using the technique of cognitive interviewing. During the translation process, 34 patients with AK from the Department of Dermatology, University Hospital Zurich, were interviewed in 3 sessions of cognitive interviewing. The translated questionnaire was then distributed together with the Dermatology Life Quality Index (DLQI) to a second group of 113 patients for validation and reliability testing. Within this group, we measured the internal consistency by the Cronbach coefficient α and Spearman correlation coefficient between the AKQoL and the DLQI.

RESULTS

The problems encountered during the translation process led to changes in 5 categories as described by Epstein: stylistic changes, change in breadth, change in actual meaning, change in frequency and time frame, change in intensity. We found a Cronbach α of 0.82, an acceptable internal consistency. The Spearman correlation coefficient between total scores of AKQoL and DLQI was 0.57.

CONCLUSION

We culturally adapted and validated a Swiss (German) version of the AKQoL questionnaire applicable for the population of a university center in Switzerland to measure and monitor the quality of life in patients with AK.
