摘要

Background

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality worldwide, often complicated by hospital-acquired pneumonia (HAP) or ventilator-associated pneumonia (VAP). These infections may contribute to prolonged hospitalizations and increased morbidity. We conducted a systematic review and meta-analysis to identify predicting factors associated with the development of pneumonia (HAP or VAP) in patients hospitalized following acute TBI.

Methods

We conducted a comprehensive search of Medline and Embase from inception to 29 September 2025. We included studies that investigated prognostic factors for HAP or VAP in adult patients admitted to hospital with TBI and adjusted for known cofounders. We pooled adjusted odds ratios (aORs) using a random-effects model. We assessed risk of bias using the QUIPS tool and certainty of findings using GRADE methodology.

Results

We included 24 studies involving 34,841 patients. Prognostic factors with a moderate or high association of developing HAP or VAP include male sex (aOR 1.52, 95% CI 1.16–2.01; high certainty), lower Glasgow Coma Scale at any time (aOR 6.36, 95% CI 1.91–21.14; moderate certainty), chest injury severity (aOR 1.56, 95% CI 1.02–2.40; moderate certainty), barbiturate use (aOR 1.83, 95% CI 0.88–3.83; moderate certainty), and the need for invasive mechanical ventilation (aOR 6.22, 95% CI 4.05–9.55; moderate certainty). We also found that early antibiotic use (aOR 0.40, 95% CI 0.23–0.72; moderate certainty) is probably associated with a reduced incidence of pneumonia.

Conclusions

Pneumonia in patients with TBI is influenced by patient characteristics, injury severity, and treatment-related factors. Recognizing these risk factors may guide early interventions to reduce pneumonia and improve patient outcomes.
