Aims
The objective of this systematic review and meta-analysis is to estimate the prevalence and incidence of diabetic peripheral neuropathy (DPN) in Latin America and the Caribbean (LAC).
Materials and methods
We searched MEDLINE, SCOPUS, Web of Science, EMBASE and LILACS databases of published observational studies in LAC up to December 2020. Meta-analyses of proportions were performed using random-effects models using Stata Program 15.1. Heterogeneity was evaluated through sensitivity, subgroup, and meta-regression analyses. Evidence certainty was performed with the GRADE approach.
Results
Twenty-nine studies from eight countries were included. The estimated prevalence of DPN was 46.5% (95%CI: 38.0–55.0) with a significant heterogeneity (I2 = 98.2%; p<0.01). Only two studies reported incidence, and the pooled effect size was 13.7% (95%CI: 10.6–17.2). We found an increasing trend of cumulative DPN prevalence over time. The main sources of heterogeneity associated with higher prevalence were diagnosis criteria, higher A1c (%), and inadequate sample size. We judge the included evidence as very low certainty.
Conclusion
The overall prevalence of DPN is high in LAC with significant heterogeneity between and within countries that could be explained by population type and methodological aspects. Significant gaps (e.g., under-representation of most countries, lack of incidence studies, and heterogenous case definition) were identified. Standardized and population-based studies of DPN in LAC are needed.
Introducción: El presente artículo resume el proceso de elaboración de la Guía de Práctica Clínica (GPC) para el manejo de dolor en pacientes oncológicos. Este proceso se llevó a cabo con la participación de un equipo multidisciplinario de médicos asistenciales, metodólogos y diversos revisores externos (especialistas con dominio en la metodología y el tema). La priorización de preguntas PICO fue realizada por el Grupo Elaborador de la GPC (GEG), acordando trabajar cinco preguntas PICO. Para dar respuesta a las preguntas se realizó una búsqueda sistemática de GPC, revisiones sistemáticas y estudios primarios. Se utilizó la metodología GRADE y los lineamientos de la normativa nacional para la formulación de recomendaciones. Se formularon 12 recomendaciones (10 fuertes y 2 débiles), 5 puntos de buena práctica clínica y 4 cuadros consensuados sobre el manejo de dolor oncológico. Los temas que abarcaron las recomendaciones para el manejo de dolor en pacientes oncológicos fueron: intervención temprana de tratamiento, terapia analgésica en dolor leve a moderado y en dolor moderado a severo, dolor neuropático e intervenciones no farmacológicas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
