Admission Dysphagia Screening Linked to Lower Aspiration Pneumonia Risk
In a retrospective cohort of 12,374 adults admitted to general wards at a Japanese hospital, adherence to a nurse-led admission dysphagia screening protocol was associated with fewer cases of hospital-acquired aspiration pneumonia. The observational findings do not establish that screening caused the reduction.
- Cohort included 12,374 general-ward admissions.
- Pneumonia incidence was 0.8% with protocol adherence versus 2.1%.
- Adjusted risk ratio was 0.424 (95% CI, 0.272–0.663).
- Single-center retrospective design limits causal conclusions.
Researchers evaluated a nurse-led admission protocol that used the Eating Assessment Tool-10, followed by the repetitive saliva swallowing test and mealtime observation. The retrospective cohort included 12,374 adults admitted to general wards between March 2022 and February 2023; 10,947 patients were managed according to the protocol and 1,427 were not. Aspiration pneumonia cases identified through ICD-10 codes were checked against medical records.
Hospital-acquired aspiration pneumonia occurred in 0.8% of protocol-adherent patients and 2.1% of non-adherent patients. After adjustment for demographic and clinical factors, protocol adherence was associated with lower risk (risk ratio, 0.424; 95% CI, 0.272–0.663; p<0.001). Cerebrovascular disease, dementia and respiratory disease were associated with higher incidence.
The findings support further evaluation of admission swallowing assessment as a potential component of hospital pneumonia-prevention strategies. However, this was a single-center retrospective study: adherence was not randomized, and residual confounding may explain some of the association. The study does not show that screening itself prevents pneumonia.
In practice
For adults admitted to general hospital wards, this single-center retrospective cohort found that adherence to a nurse-led dysphagia screening protocol was associated with lower hospital-acquired aspiration pneumonia incidence. The result may inform local evaluation of admission swallowing-assessment processes, but it does not establish that screening caused the reduction or show which protocol components mattered. The study was not randomized, and findings from one Japanese hospital may not generalize to other settings; the evidence alone does not establish a practice change.
