Key Points

To evaluate the disparities in critical care research output between high-income countries and middle/low-income countries over five years.
Conducted a bibliometric analysis of published critical care literature from 2018 to 2022.
Compared research outputs from high-income countries with those from middle and low-income countries.
Analyzed trends in publication percentages and research focus areas.
High-income countries produced 90% of critical care publications during the study period.
Notable mismatch found between research focus and critical illness burden in middle/low-income countries.
Recommendations for improving research output in underrepresented regions were identified.

Implication

Analysis assesses disparities in critical care research production between countries of different income levels, indicating inequality in health focus.

Abstract

INTRODUCTION Inequality in scientific production is a persistent global health issue.(1) In critical care, high-income countries (HICs) accounted for up to 90% of published papers between 2018 and 2022.(2,3) This concentration may lead to a mismatch between the research focus and the critical illness burden, which disproportionately affects middle and low-income countries (M/LICs).(4) To assess […]
