Abstract

As part of a systematic literature review, a comprehensive literature search was carried out to identify risk factors for aspiration pneumonia in frail older people. A prominent risk factor found was dysphagia with evidence level 2a, according to the Oxford Centre for Evidence-based Medicine Levels of Evidence. Subsequently, a meta-analysis of 4 cohort, 1 case-cohort, and 1 case-control study on dysphagia as a risk factor of aspiration pneumonia in frail older people was performed. Using a random effects model, we found a positive correlation between dysphagia and aspiration pneumonia: OR = 9.84; 95%CI = 4.15 - 23.33 (test for statistical homogeneity: p < 0.001). Then, a subgroup meta-analysis was performed with 4 cohort studies, all including patients with a cerebrovascular disease. Once again, a positive correlation was found between dysphagia and aspiration pneumonia: OR = 12.93; 95%CI = 8.61 - 19.44. The test for statistical homogeneity revealed no statistically significant result (p = 0.15). It was concluded that dysphagia is a serious risk factor for aspiration pneumonia in frail older people, particularly in those suffering from a cerebrovascular disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
