Higher texture-modified diet intake rates were associated with better functional status after multivariable adjustment, suggesting that monitoring TMD intake may help identify patients who warrant closer nutritional and swallowing assessment.
Key Findings
Results
Each 10% increase in texture-modified diet intake rate was associated with lower odds of a higher modified Rankin Scale category at hospital discharge.
Adjusted odds ratio of 0.85 (95% CI, 0.77–0.94) per 10% increase in TMD intake for discharge mRS
Analysis used ordinal logistic regression models for mRS scores
Models were adjusted for age, sex, admission NIHSS score, premorbid mRS, stroke type, and admission Geriatric Nutritional Risk Index (GNRI)
Study included 406 patients with ischemic stroke or intracerebral hemorrhage who received TMDs between 2012 and 2017
Results
Each 10% increase in texture-modified diet intake rate was associated with lower odds of a higher modified Rankin Scale category at 90 days after stroke.
Adjusted odds ratio of 0.88 (95% CI, 0.80–0.96) per 10% increase in TMD intake for 90-day mRS
The association was statistically significant at 90 days as well as at discharge
Same multivariable adjustment covariates were applied as for the discharge outcome
Results
Higher TMD intake was associated with higher odds of a favorable functional outcome (mRS 0–2) at hospital discharge.
Adjusted odds ratio of 1.31 (95% CI, 1.03–1.66) per 10% increase in TMD intake for favorable outcome at discharge
Favorable outcome was defined as mRS score of 0–2
This was performed as a secondary binary logistic regression analysis
Results
The association between higher TMD intake and favorable outcome (mRS 0–2) at 90 days was not statistically significant.
Adjusted odds ratio of 1.15 (95% CI, 0.98–1.35) per 10% increase in TMD intake for 90-day favorable outcome
The confidence interval crossed 1.0, indicating non-significance
This contrasted with the statistically significant association seen at discharge
Methods
The study population consisted of 406 stroke patients who received texture-modified diets for suspected or confirmed dysphagia at a single center.
Patients had either ischemic stroke or intracerebral hemorrhage
Data were collected retrospectively from 2012 to 2017
TMD intake was calculated as the meal-count-weighted mean consumption proportion across four TMD levels
This was a retrospective single-center observational study
Results
Diet-specific associations between individual TMD texture levels and functional outcomes were inconsistent.
Associations differed across the four TMD levels examined
No consistent pattern of association was found when TMD levels were analyzed separately
Overall TMD intake rate was therefore analyzed as a composite meal-count-weighted mean
Discussion
The authors cautioned that observational findings do not establish causality because TMD intake may reflect swallowing impairment, clinical condition, and early recovery rather than being an independent cause of better outcomes.
TMD intake may act as a surrogate marker for swallowing function and overall clinical status
The study design was retrospective and single-center, limiting generalizability
The authors noted that 'these observational findings do not establish causality'
Monitoring TMD intake was suggested as a tool to identify patients warranting closer nutritional and swallowing assessment
What This Means
This research suggests that stroke patients who eat a higher proportion of their prescribed texture-modified meals tend to have better functional recovery, both at hospital discharge and three months after their stroke. Texture-modified diets (such as pureed or minced foods) are commonly given to stroke patients who have trouble swallowing, but until now it was unclear whether how much patients actually ate of these diets made a difference to their recovery. The study tracked 406 stroke patients and found that for every 10% more of their prescribed texture-modified meals that patients consumed, their odds of having worse disability at discharge decreased by about 15%, and their odds of worse disability at 90 days decreased by about 12%.
However, the researchers are careful to point out that this does not necessarily mean eating more of these modified meals directly causes better recovery. It is quite possible that patients who are recovering better are simply more able to eat — meaning that eating more could be a sign of better health rather than a cause of it. Swallowing difficulty, overall medical condition, and early neurological recovery could all influence how much a patient eats. The study was also conducted at a single hospital looking back at historical records, which limits how broadly the findings can be applied.
This research suggests that tracking how much of their texture-modified diet stroke patients actually consume could be a useful clinical tool. Patients who are eating very little of their prescribed diet may need closer attention from nutrition and swallowing specialists. This kind of monitoring could potentially help medical teams identify patients at higher risk of poor recovery earlier in their hospital stay.
