A Review of Factors Contributing to Adults' Adherence to Dysphagia Dietary Recommendations Through an Ecological Lens

Communicating Risks and Food Procedures through a Visual Poster for Caregivers of Patients with Dysphagia in Inpatient Care: Usability and Impact

Food-related procedures are a part of rehabilitation interventions for dysphagia. However, studies show that professional-caregiver communication is often lacking in dysphagia, risking caregivers' knowledge, understanding, and practice of those procedures, with negative consequences for patient safety and rehabilitation. The aim of this study was to evaluate caregivers' perspectives about the utility of a poster designed to communicate dysphagia-related risks and food procedures for caregivers of patients in inpatient care. The impact of caregivers' exposure to the poster on patients' dysphagia-related health was additionally explored. The poster was placed by the beds of a randomly assigned group of patients (n = 21). Their caregivers responded to a questionnaire about the poster's utility. In addition, to explore whether the caregiver exposure to the poster could already have some effect on patient dysphagia-related health, patient risk of aspiration, food swallowing capacity, nutritional status, and oral cavity health were assessed before and one month after placement of the poster, and the poster-exposed group was compared with a (randomly-assigned) non-exposed group (n = 21). Data were analyzed with descriptive statistics and generalized linear models based on analyses of covariance. All caregivers across various education levels reported noticing, reading, and understanding the poster (100%). Nearly all reported that the poster added new information to their knowledge (17 out of 21). In the additional analysis, the patients in the poster-exposed group showed greater improvements in the health outcomes, compared with the non-exposed group, although the effects were statistically non-significant within this study's one-month period. A poster with pictorial information was effective in increasing awareness about dysphagia-specific information among caregivers of patients in inpatient care and can be used as an augmentative means of information, with potential benefits for patient safety and rehabilitation.

Stratifying Risk of Nonadherence in Lingual Strengthening Dysphagia Rehabilitation

PURPOSE

Exercise-based treatments may improve swallowing safety and efficiency; yet, it is not clearly understood which factors predict nonadherence to recommended treatment protocols. The aim of this study was to construct an algorithm for stratifying risk of nonadherence to a lingual strengthening dysphagia treatment program.

METHOD

Using recursive partitioning, we created a classification tree built from a pool of sociodemographic, clinical, and functional status indicators to identify risk groups for nonadherence to an intensive lingual strengthening treatment program. Nonadherence, or noncompletion, was defined as not completing two or more follow-up sessions or a final session within 84 days.

RESULTS

The study cohort consisted of 243 Veterans enrolled in the Intensive Dysphagia Treatment program across six sites from January 2012 to August 2019. The overall rate of nonadherence in this cohort was 38%. The classification tree demonstrated good discriminate validity (C-statistic = 0.74) and contained eight groups from five variables: primary diagnosis, marital status, Penetration-Aspiration Scale (PAS) severity score, race/ethnicity, and age. Nonadherence risk was categorized as high (range: 69%-77%), intermediate (27%-33%), and low risk (≤ 13%-22%).

CONCLUSIONS

This study identified distinct risk groups for nonadherence to lingual strengthening dysphagia rehabilitation. Additional research is necessary to understand how these factors may drive nonadherence. With external validation and refinement through prospective studies, a clinically relevant risk stratification tool can be developed to identify patients who may be at high risk for nonadherence and provide targeted patient support to mitigate risk and provide for unmet needs.
