Bibliometric Analysis of Studies on Delirium in Critical Care.

BACKGROUND

Delirium leads to prolongation in intensive care unit (ICU) and hospital length of stay and an increase in ICU costs and mortality. As a result of this, the number of studies on delirium in ICUs has recently increased significantly, and many articles have been published.

OBJECTIVES

The aim of this study was to evaluate the articles related to "delirium" in "critical care" field in the Web of Science database and the first hundred most cited articles on this subject.

METHODS

The Web of Science database was searched for articles relevant to "delirium" in the critical care medicine field published between 1980 and 2024. Text analytics and network models used in bibliometric mapping were used for prolific authors, annual trend, citation, and countries.

RESULTS

In our study, it was determined that a total of 1834 articles in the field of delirium in critical care medicine were included. It was determined that the annual citation average was 42.79 and the H-index value was 134. There is a general upward trend over the years, and it was observed that it has intensified in the last 5 to 6 years. With the Reference Spectroscopy analysis, it was determined that the most intensively cited studies on delirium were the studies of 2013 and 2010. The distribution of keywords in recent years has focused on analgosedation, acute brain injury, older patient, COVID-19, and fragility. When examined for the top 100 cited articles, it was seen that mobilization, guidelines, pain, activities of daily living, anesthesia, sedation, and haloperidol have become prominent in recent years.

CONCLUSION

In recent years, there has been a noticeable increase in the volume of research focusing on delirium studies within the field of critical care medicine. Staying current with trends, incorporating findings from frequently cited studies, and customizing interventions to suit modern difficulties can all improve the quality of care offered to critically ill patients and lead to better outcomes.
