The burden of bacterial skin infection, scabies and atopic dermatitis among urban-living Indigenous children in high-income countries: a protocol for a systematic review.

Background: Bacterial skin infections and scabies disproportionately affect children in resource-poor countries as well as underprivileged children in high-income countries. Atopic dermatitis is a common childhood dermatosis that predisposes to bacterial skin infection. In Australia, at any one time, almost half of all Aboriginal and Torres Strait Islander children living remotely will have impetigo, and up to one-third will also have scabies. Yet, there is a gap in knowledge of the skin infection burden for urban-living Australian Aboriginal and Torres Strait Islander children, as well as atopic dermatitis which may be a contributing factor. The objective of this study is to provide a global background on the burden of these disorders in Indigenous urban-living children in high-income countries. These countries share a similar history of colonisation, dispossession and subsequent ongoing negative impacts on Indigenous people. Methods: This protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols statement. Observational studies reporting incidence and/or prevalence data on bacterial skin infection, scabies and/or atopic dermatitis in urban-living Indigenous children in high-income countries will be included. Literature searches will be conducted in several international electronic databases (from 1990 onwards), including MEDLINE, Embase, EmCare, Web of Science and PubMed. Reference lists and citation records of all included articles will be scanned for additional relevant manuscripts. Two investigators will independently perform eligibility assessment of titles, abstract and full-text manuscripts, following which both investigators will independently extract data. Where there is disagreement, the senior author will determine eligibility. The methodological quality of selected studies will be appraised using an appropriate tool. Data will be tabulated and narratively synthesised. We expect there will be insufficient data to perform meta-analysis. Discussion: This study will identify and evaluate epidemiological data on bacterial skin infection, scabies and atopic dermatitis in urban-living Indigenous children in high-income countries. Where available, the clinical features, risk factors, comorbidities and complications of these common childhood skin disorders will be described. The evidence will highlight the burden of disease in this population, to contribute to global burden of disease estimates and identify gaps in the current literature to provide direction for future research.
