Annotated Bibliography: Bedside Dysphagia Screening and Aspiration Prevention After Acute Stroke

Clinical Area and Purpose

Swallowing problems affect a large share of patients in the first days after an acute stroke, because damage to the cortex, the corticobulbar tracts or the brainstem swallowing centers delays the swallow reflex, weakens the tongue and pharynx and blunts the cough that normally protects the airway. Some patients aspirate silently, with no cough at all. The result is a risk of aspiration pneumonia, malnutrition and dehydration that nurses can reduce by screening every patient before any food, fluid or oral medication is given. As a nurse on a stroke unit, I chose this area to find out which screening tools are most accurate, what guidelines ask nurses to do, how nurses should be trained and which follow-up care lowers pneumonia risk.

Boaden, E., Burnell, J., Hives, L., Dey, P., Clegg, A., Lyons, M. W., Lightbody, C. E., Hurley, M. A., Roddam, H., McInnes, E., Alexandrov, A., & Watkins, C. L. (2021). Screening for aspiration risk associated with dysphagia in acute stroke. Cochrane Database of Systematic Reviews, 2021(10), Article CD012679. https://doi.org/10.1002/14651858.CD012679.pub2

This Cochrane diagnostic accuracy review asked how well bedside screening tests performed by nurses and other health professionals detect aspiration risk in adults with acute stroke, compared with expert or instrumental assessment. Boaden et al. (2021) included 25 studies with 3,953 participants and 37 screening tests. Water-only tests showed sensitivity from 46% to 100% and specificity from 43% to 100%, while tests using water and other consistencies ranged from 75% to 100% for sensitivity and 69% to 90% for specificity. The best-performing tools in their categories were the Bedside Aspiration test, the Gugging Swallowing Screen and the Toronto Bedside Swallowing Screening Test, but each rested on a single small study. Strengths include Cochrane methods, independent screening by two authors and a formal risk of bias assessment with QUADAS-2. The weakness is the honesty of its conclusion: no tool had high, precisely estimated accuracy from a low-bias study, so the review could not crown a winner. Its searches also ended in December 2019. For practice, it supports using a screen that tests more than one consistency while recognizing that any screen is a first step before a full assessment.

Gardiner et al. (2026) mapped what training stroke nurses receive before they screen swallowing. Searching MEDLINE, CINAHL and Scopus under the PRISMA-ScR checklist, they found 318 studies and included 10. Four themes emerged: comprehensive and structured training, a variety of teaching methods, ongoing education with competency assessment, and standardized protocols and tools. Comprehensive programs were associated with more timely interventions and better outcomes, but training varied so widely that its results could not be benchmarked. The review's strengths are its current publication date, a transparent screening process and a focus on the nurse, who performs most screens. Its weaknesses follow from its design: a scoping review maps evidence rather than judging its quality, only ten studies were found, and the association between training and outcomes cannot prove that the training caused the improvement. The practical message for a unit is that competency should be checked again after initial training, not assumed for years.

This systematic review appraised guidelines on post-stroke dysphagia published between 2017 and 2022 and turned their nursing recommendations into an algorithm. From 991 records, Jiang et al. (2023) included 10 guidelines and, using the AGREE II instrument, rated 5 as high quality. They summarized 27 recommendations from those five and organized them by the nursing process, from assessment and diagnosis to intervention and evaluation. The main strength is the use of a validated appraisal tool, which separates strong guidelines from weak ones instead of treating all recommendations as equal. The algorithm also gives bedside nurses a single pathway. Weaknesses include the narrow five-year window for guidelines, which may have excluded influential older documents, and the fact that the algorithm itself was not tested with patients. The authors also found real variability among guidelines, which means local policy still has to choose among them. For my unit, the algorithm offers a template to compare against our current protocol.

Jiang et al. (2024) used a network meta-analysis to compare six bedside tools against videofluoroscopy or endoscopic evaluation. They screened 6,979 records and included 21 studies with 3,314 participants from 10 countries. The Gugging Swallowing Screen, the Mann Assessment of Swallowing Ability and the volume-viscosity swallow test performed best; the Gugging screen showed a sensitivity of 92% and specificity of 85%, and the Mann assessment 89% and 83%. The water swallow test and the Bedside Swallowing Screening Test were less accurate. A network design is a strength because it compares tools that were never tested against each other directly, and the search ran to December 2023. The authors report low heterogeneity and publication bias. Weaknesses include pooling studies with different reference standards and settings, and the contrast with the more cautious Cochrane review suggests the pooled figures may be more confident than the underlying studies allow. Read alongside Boaden et al. (2021), it supports choosing a multiconsistency screen such as the Gugging Swallowing Screen.

Because aspiration pneumonia develops when bacteria from the mouth reach the lungs, oral care is the natural partner of screening. Lu et al. (2026) gathered the best evidence on oral health care for patients with post-stroke dysphagia, searching guideline sites, decision systems and databases through December 2025. They included 17 publications, namely 10 guidelines, 3 expert consensus statements, 1 clinical decision aid and 3 evidence summaries, and extracted 21 pieces of evidence in four domains: team formation, screening and assessment, nursing interventions and health education. Key recommendations included nurse-led multidisciplinary collaboration, standardized oral and swallowing assessments, brushing twice a day with a soft toothbrush, careful use of chlorhexidine mouthwash and caregiver training before discharge. The strengths are its recency and its practical, nurse-centered framework. Its weakness is that it synthesizes guidelines and consensus rather than original trials, so the strength of each recommendation depends on the documents it drew from. On my unit, it supports adding a twice-daily oral care check to the dysphagia pathway.
