Forecasting models for leprosy cases: a scoping review protocol

Abstract

IntroductionLeprosy is a neglected tropical disease caused by Mycobacterium leprae that mainly affects the skin, the peripheral nerves, the mucosa of the upper respiratory tract and the eyes. Mathematical models and statistical methodologies could play an important role in decision-making and help maintain the gains in elimination programmes. Various models for predicting leprosy cases have been reported in the literature, but they have different settings and distinct approaches to predicting the cases. This study describes the protocol for a scoping review to identify and synthesise information from studies using models to forecast leprosy cases.Methods and analysisA scoping review methodology will be applied following the Joanna Briggs Institute methodology for scoping reviews and will be reported according to Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews. We will perform a systematic search from when each database started until April 2022 and we will include the following electronic databases: MEDLINE via PubMed, Embase, Cochrane Library and Latin American and Caribbean Health Science Literature Database. Data will be extracted and recorded on a calibrated predefined data form and will be presented in a tabular form accompanied by a descriptive summary. The Prediction Model Study Risk of Bias Assessment Tool (PROBAST) will be used.Ethics and disseminationNo ethical approval is required for this study. This scoping review will identify and map the methodological and other characteristics of modelling studies predicting leprosy cases. We hope that the review will contribute to scientific knowledge in this area and act as a basis for researchers designing and conducting leprosy models. This information can also be used to enhance national surveillance systems and to target specific policies. The protocol and consequent publications of this scoping review will be disseminated through peer-reviewed publications and policy briefs.Systematic review registrationThis scoping review was registered in the Open Science Framework (https://doi.org/10.17605/OSF.IO/W9375).

Políticas públicas e fatores socioeconômicos na dinâmica da hanseníase no Estado do Pará

“…Para o melhor entendimento destas variáveis que norteiam a dinâmica da hanseníase em nossa sociedade é relevante o emprego de técnicas multivariadas que permitam análises das diferentes interrelações existentes, quando corretamente utilizadas, estas ferramentas podem desempenhar um papel relevante na tomada de decisão para a manutenção de programas para a eliminação de hanseníase e na identificação e vigilância de casos novos, ainda que existam diferentes abordagens metodológicas, ou dificuldades práticas como fontes de dados confiáveis e tratamento de eventual subnotificação de casos 7 .…”
