This retrospective cohort study was conducted in accordance with the Declaration of Helsinki and approved by the Ethics Committee of Suzhou Hospital, Affiliated Hospital of Medical School, Nanjing University (Approval No. IRB2025091). The manuscript was revised in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement for cohort studies. The study used routinely collected, anonymized clinical data; the consent process complied with institutional ethics requirements for retrospective research.
1. Study design, setting, and cohort assembly
This single-center retrospective cohort study included consecutive adult patients admitted between January 2020 and May 2025. Eligibility criteria were age ≥18 years, stroke confirmed by CT or MRI, dysphagia identified by a bedside water swallow test and/or videofluoroscopic swallowing study (VFSS), and complete medical and nursing records during the index hospitalization. Exclusion criteria were pre-existing swallowing disorders unrelated to stroke (such as esophageal disease or head and neck tumors), severe cognitive impairment or inability to cooperate with swallowing assessment, concomitant progressive neurological disease (such as Parkinson's disease), and incomplete in-hospital follow-up data. Of 247 screened patients, 37 were excluded, leaving 210 for the final analysis (Figure 1). Patients were assigned to the conventional care or clinical pathway group according to the nursing model documented in the medical record during the index admission.
2. Baseline and follow-up swallowing assessment
Baseline swallowing assessment was completed within 24 h of dysphagia recognition. Bedside screening used a 30 mL water swallow test performed with the patient in a seated or semi-recumbent position. Results were recorded as follows: Grade I, one uninterrupted swallow without coughing; Grade II, more than one swallow without coughing; Grade III, one swallow with coughing, throat clearing, or a wet voice; Grade IV, multiple swallows with coughing, throat clearing, or a wet voice; and Grade V, inability to complete the test safely5,6. When aspiration risk remained uncertain, silent aspiration was suspected, or dietary advancement decisions required imaging confirmation, the rehabilitation team performed VFSS using standard lateral fluoroscopic observation of liquid and semi-solid boluses. Swallowing status was reassessed during hospitalization and again at discharge using the same clinical workflow. Improvement in swallowing function was defined as at least a one-grade reduction in dysphagia severity between admission and discharge and/or documented improvement on VFSS.
3. Conventional nursing care
Conventional nursing care consisted of routine dysphagia management delivered during hospitalization, including basic diet texture modification, general feeding precautions, simple postural guidance, and non-standardized swallowing exercises. The frequency and intensity of these interventions depended on routine ward practice and the patient’s clinical condition, but they were not delivered within a predefined multidisciplinary pathway.
4. Clinical pathway-based rehabilitation nursing
The clinical pathway group received a standardized nursing program jointly implemented by neurologists, rehabilitation physicians, rehabilitation nurses, and dietetic support personnel (Figure 2).
- Initial assessment phase (day 0-1)
Within 24 h of dysphagia identification, nurses documented water swallow test grade, level of consciousness, cough strength, respiratory status, feeding safety, nutritional risk, and aspiration history. Oral intake was deferred or restricted in patients with clear aspiration risk until team review.
- Early intervention phase (day 1-3)
Patients received upright positioning during feeding, oral hygiene, individualized diet texture adjustment, feeding pace control, and compensatory swallowing postures. Enteral feeding support was maintained when oral feeding was considered unsafe.
- Daily rehabilitation phase
Oropharyngeal muscle strengthening and tongue-lip mobility exercises were delivered for 15-20 min twice daily when tolerated. Breathing-swallow coordination training was delivered for approximately 10-15 min daily. Safe-feeding training and compensatory posture practice were reinforced at each supervised meal. Nurses monitored coughing, wet voice, oxygen desaturation, sputum burden, and intake tolerance after each feeding session.
- Reassessment and pathway adjustment
A multidisciplinary review was performed every 48-72 h, or earlier if clinical deterioration occurred. Diet texture was advanced only when the patient tolerated the current diet without obvious choking or desaturation for 24-48 h, and reassessment supported progression. VFSS was repeated when bedside findings were inconsistent with clinical symptoms or when aspiration risk remained unclear.
- Discharge preparation
Before discharge, nurses repeated the swallowing assessment, reviewed aspiration precautions, instructed caregivers on feeding posture and home exercises, and documented a home rehabilitation plan.
5. Outcome measures and variable definitions
The primary outcomes were improvement in swallowing function by discharge and the absence of aspiration pneumonia during hospitalization. Aspiration pneumonia was diagnosed based on clinical symptoms, radiographic findings, and, when available, microbiological data. Secondary outcomes included discharge serum albumin (≥35 g/L vs. <35 g/L), discharge functional recovery (Barthel Index ≥70), length of ICU stay, overall in-hospital complication rate, and length of hospital stay. Demographic and clinical covariates included age, sex, stroke type, smoking history, alcohol consumption, hypertension, diabetes mellitus, dyslipidemia, body mass index (BMI), family history of stroke, and dysphagia severity at baseline.
6. Statistical analysis
Data were analyzed using SPSS version 25.0 (IBM Corp., Armonk, NY, USA). Continuous variables were tested for normality using the Kolmogorov–Smirnov test. Normally distributed continuous variables were expressed as mean ± standard deviation and compared using the independent-samples t test; non-normally distributed data were summarized as median (interquartile range) and compared using the Mann–Whitney U test. Categorical variables were expressed as n (%) and compared using the chi-square test or Fisher’s exact test, as appropriate. Multivariable logistic regression was used to identify factors independently associated with swallowing improvement, with adjusted models including prespecified demographic and clinical covariates recorded in the medical record. All tests were two-sided, and P < 0.05 was considered statistically significant.
