Repercussions of the Emergency neurological life support on scientific literature: a bibliometric study

Abstract

Background In 2012, the Neurocritical Care Society launched a compilation of protocols regarding the core issues that should be addressed within the first hours of neurological emergencies – the Emergency neurological life support (ENLS).

Objective We aim to evaluate this repercussion through a bibliometric analysis.

Methods We searched Scopus on October 2022 for articles mentioning ENLS. The following variables were obtained: number of citations; number of citations per year; number of publications per year; year of publication; research type; research subtype; country of corresponding author and its income category and world region; journal of publication and its 5-year impact factor (IF); and section where ENLS appeared.

Results After applying eligibility criteria, we retrieved 421 articles, published from 2012 to 2022. The mean number of citations per article was 17.46 (95% Confidence Interval (CI) = 8.20–26.72), while the mean number of citations per year per article was 4.05 (95% CI = 2.50–5.61). The mean destiny journal 5-year IF was 5.141 (95% CI = 4.189–6.093). The majority of articles were secondary research (57.48%; n = 242/421) of which most were narrative reviews (71.90%; n = 174/242). High-Income countries were the most prominent (80.05%; n = 337/421 articles). There were no papers from low-income countries. There were no trials or systematic reviews from middle-income countries.

Conclusion Although still low, the number of publications mentioning ENLS is increasing. Articles were mainly published in journals of intensive care medicine, neurology, neurosurgery, and emergency medicine. Most articles were published by authors from high-income countries. The majority of papers were secondary research, with narrative review as the most frequent subtype.

Resumo

Antecedentes Em 2012, a Neurocritical Care Society lançou uma compilação de protocolos sobre as questões centrais que devem ser abordadas nas primeiras horas de emergências neurológicas – Emergency neurological life support (ENLS).

Objetivo Avaliar a repercussão do ENLS por meio de uma análise bibliométrica.

Métodos A base de dados Scopus foi utilizada em outubro de 2022 para a busca por artigos mencionando o ENLS. As seguintes variáveis foram obtidas: número de citações; número de citações por ano; número de publicações por ano; ano de publicação; tipo de pesquisa; país do autor correspondente e sua categoria de renda; revista de publicação e seu fator de impacto de 5 anos (IF); e seção onde o ENLS apareceu.

Resultados Os 421 artigos incluídos foram publicados de 2012 a 2022. A média de citações por artigo foi de 17.46 (intervalo de confiança (IC) 95% = 8.20–26.72), enquanto a de citações por ano por artigo foi de 4.05 (IC95% = 2.50–5.61). O IF médio por revista foi de 5.14 (IC95% = 4.19–6.09). A maioria dos artigos era de pesquisa secundária (57.48%; n = 242/421), dos quais a maioria eram revisões narrativas (71.90%; n = 174/242). Os países de alta renda foram os mais prolíficos (80.05%; n = 337/421 artigos). Não houve publicações de países de baixa ou média renda.

Conclusão Embora ainda baixo, o número de publicações mencionando o ENLS vem aumentando recentemente. A maioria dos artigos foram publicados em revistas de medicina intensiva, neurologia, neurocirurgia e medicina de emergência. Artigos de pesquisa secundária foram os mais comuns, com revisões narrativas sendo o subtipo mais frequente.
