Classifying atopic dermatitis: protocol for a systematic review of subtypes (phenotypes) and associated characteristics.

ABSTRACT:

Introduction

Atopic dermatitis is a complex disease with differing clinical presentations. Many attempts have been made to identify uniform subtypes, or phenotypes, of atopic dermatitis in order to identify different aetiologies, improve diagnosis, estimate more accurate clinical prognoses, inform treatment andmanagement or predict treatment efficacy andeffectiveness. However, no consensus yet exists on exactly what defines these phenotypes or how many there are and whether they are genuine or statistical artefacts. This review aims to identify previously reported phenotypes of atopic dermatitis, the features used to define them and any characteristics or clinical outcomes significantly associated with them.

Methods and analysis

We will search Ovid Embase, Ovid MEDLINE and Web of Science from inception to the latest available date at the time of the search for studies attempting to classify atopic dermatitis in humans using any cross-sectional or longitudinal epidemiological or interventional design. Primary outcomes are atopic dermatitis phenotypes, features used to define them and characteristics associated with them in subsequent analyses. A secondary outcome is the methodological approach used to derive them. Two reviewers will independently screen titles and abstracts for inclusion, extract data and assess study quality. We will present the results of this review descriptively and with frequencies where possible.

Ethics and dissemination

Ethical approval is not required for this study as it is a systematic review. We will report results from this systematic review in a peer-reviewed journal. The main value of this study will be to inform further research.

Project description:BackgroundNumerous therapies have recently emerged for treatment of patients with atopic dermatitis (AD), a common skin disease, and understanding their cost-effectiveness is of high importance for policy makers. This systematic literature review (SLR) aimed to provide an overview of full economic evaluations that assessed cost-effectiveness of emerging AD treatments.MethodsThe SLR was conducted in Medline, Embase, UK National Health Service Economic Evaluation Database and EconLit. Reports published by the National Institute for Health and Care Excellence, the Institute for Clinical and Economic Review and the Canadian Agency for Drugs and Technologies in Health were manually searched. Economic evaluations published from 2017 to September 2022 that compared emerging AD treatments with any comparator were included. Quality assessment was conducted by using the Consensus on Health Economic Criteria list.ResultsA total of 1333 references were screened after removing duplicates. Among those references, 15 that conducted a total of 24 comparisons were included. Most studies were from the USA, UK or Canada. Seven different emerging treatments were compared, mostly with usual care. In 15 comparisons (63%), the emerging treatment was cost-effective, and 11 out of 14 dupilumab comparisons (79%) reported that dupilumab was cost-effective. Upadacitinib was the only emerging therapy that was never classified as cost-effective. On average, 13 out of 19 quality criteria (68%) per reference were rated as fulfilled while manuscripts and health technology reports received generally higher quality assessment scores than published abstracts.DiscussionThis study revealed some discrepancies in the cost-effectiveness of emerging therapies for AD. A variety of designs and guidelines made comparison difficult. Therefore, we recommend that future economic evaluations use more similar modelling approaches to improve comparability of results.OthersThe protocol was published in PROSPERO (ID: CRD42022343993).
