Brief summary

This study investigates 5-fluorouracil cream prescription trends by general practitioners for the treatment of field changes of actinic keratosis over the years 2016-2021. The aim is to analyse whether the publication of the multidisciplinary guideline on suspect skin lesions for general practitioners in 2017 has made an impact in the prescribing behaviour of general practitioners.

Detailed description

Actinic keratosis is the most common epithelial precancerous lesion among the Caucasian race. With an increase in prevalence worldwide due to an aging population and rise of ultraviolet exposure actinic keratosis are among the most frequently encountered skin lesions in clinical practice. Both dermatologists and general practitioners are increasingly confronted with actinic keratosis, entailing to higher healthcare costs and time burden. There are many therapeutic modalities for the treatment of actinic keratosis, depending on multiple factors such as distribution, characteristics, patient preference, side effects, availability and costs. Treatment options can be divided into: lesion directed therapy en field directed therapy. Both dermatologists and general practitioners can treat actinic keratosis and 5-fluorouracil cream can also be prescribed by general practitioners. The objective of this study was to investigate 5-fluorouracil cream prescription trends by general practitioner for the treatment of field changes of actinic keratosis over the years 2016-2021.
