Association of Admission Times on Mortality in Adult Patients with Severe Community-Acquired Pneumonia

Abstract

Objectives

The objective of this study was to examine the association between admission time and in-hospital mortality in patients with severe community-acquired pneumonia.

Research Design

The study population consisted of individuals who were enrolled between January 2019 and December 2023. These individuals were divided into two groups based on the time of admission: daytime admission from 8:00 am to 6:00 pm and nighttime admission from 6:00 pm to 8:00 am The primary endpoint of the study was in-hospital mortality. Binary logistic regression was employed to assess the association between admission time and in-hospital mortality.

Results

A total of 307 patients with severe community-acquired pneumonia were ultimately enrolled in the study. Of the total number of patients, 57% (175 patients) were admitted at night. A comparative analysis of the clinical outcomes in the two groups revealed that the mortality rate for patients admitted at night was 28%, which was not significantly different from that of patients admitted during the day, which was 35.6% (P = .155). The findings from binary logistic regression analyses revealed no statistically significant correlation between nighttime admissions and in-hospital mortality.

Conclusions

This study's findings indicate that nighttime admission for patients diagnosed with severe community-acquired pneumonia is not associated with an elevated risk of mortality. Conversely, there may be a reduced mortality rate for patients admitted during nighttime hours. However, further prospective multicenter studies are required in the future to confirm this.
