PD02 Home daylight photodynamic therapy

Abstract Actinic keratoses (AK) on the face and scalp are often extensive a major cause of morbidity associated with increased risk skin cancer. Field-directed treatment approaches, such as daylight photodynamic therapy (DPDT) required, this has been shown to be effective, well-tolerated feasible in UK between April September. We have used DPDT since 2013, good outcomes. Patient engagement indicated that convenience tolerability were rated highly efficacy, we therefore developed an entirely home-based approach ‘home (H-DPDT)’ 2021. Working art-and-design student, fully recyclable home kit enable patients self-treat H-DPDT their environment. Patients selected by dermatologist then received nurse-led training prior treatment. In-person review after second was undertaken assess response decide if further needed, telephone follow-up first third treatments. Final clinician 3–6 months last reported implementation 2021 introduced into our routine PDT service options, now wish report findings from 2021–22. Seventeen (82% male) treated 2021–2022 for AK head neck. Each patient completed average four (range 2–5) Clinical (≥ 75% response) nine 15 (60%) assessed. Response moderate one (7%) (50–75% remaining five (33%) had poor (< 50% response). Treatment success correlated grade disease. more hyperkeratotic disease poorer In 2022, responded questionnaire. Of these, two Excellent other three it Good. Four stated they tried treatments, which thought H-PDT better. One felt alternative treatments effective but tolerated Three expressed preference repeat would recommend it. This innovative enables environment, initial results showed high rates satisfaction. outcomes better those milder disease, highlighting need careful selection surface preparation. As proof concept, is therapeutic option empowers patients, may place work optimize indicated.
