Dying for a Meal: An Integrative Review of Characteristics of Choking Incidents and Recommendations to Prevent Fatal and Nonfatal Choking Across Populations.

Purpose The purpose of this study was to conduct an integrative review of original research, across adult populations relating to fatal or nonfatal choking on food, to understand ways to respond to and prevent choking incidents. Method Four scientific databases (CINAHL, Medline, Web of Science, and EMBASE) were searched for original peer-reviewed research relating to fatal or nonfatal choking on foods. Data were extracted on study characteristics; factors leading up to, events at the time of, and actions taken after the choking incident; and impacts of choking incidents. An integrative review of the findings across studies identified several risk factors and recommendations to reduce the risk of choking. Results In total, 52 studies met the criteria for inclusion in this review, of which 31 were quantitative, 17 were qualitative, and 4 were of a mixed methods design. Studies reported the observations and narratives of bystanders or researchers, or else were large-scale autopsy studies, and included both the general public and people at risk of dysphagia. A range of food types were involved, and several actions were reported in response to food choking. Strategies to reduce the risk of choking were identified in the studies and are presented in 5 main categories. Conclusions Factors leading up to choking incidents extend well beyond the individual to the environment for mealtimes; the provision of appropriate mealtime assistance and oral care; and regular monitoring of general health, oral health, and medications. Bystanders' increased awareness and knowledge of how to respond to choking are vital. The results of this review could be used to inform service policy and training, for individuals at risk of choking, the people who support them, and the general public. Further research is needed to explore choking prevention and airway protection in individuals with dysphagia. Supplemental Material https://doi.org/10.23641/asha.8121131.

Validation of the Choking Risk Assessment and Pneumonia Risk Assessment for adults with Intellectual and Developmental Disability (IDD).

BACKGROUND: Risk assessments are needed to identify adults with intellectual and developmental disability (IDD) at high risk of choking and pneumonia. AIM: To describe the development and validation of the Choking Risk Assessment (CRA) and the Pneumonia Risk Assessment (PRA) for adults with IDD. METHODS: Test items were identified through literature review and focus groups. Five-year retrospective chart reviews identified a positive choking group (PCG), a negative choking group (NCG), a positive pneumonia group (PPG), and a negative pneumonia group (NPG). Participants were tested with the CRA and PRA by clinicians blind to these testing conditions. RESULTS: The CRA and PRA differentiated the PCG (n=93) from the NCG (n=526) and the PPG (n=63) from the NPG (n=209) with high specificity (0.91 and 0.92 respectively) and moderate to average sensitivity (0.53 and 0.62 respectively). Further analyses revealed associations between clinical diagnoses of dysphagia and choking (p=0.043), and pneumonia (p<0.001). CONCLUSIONS: The CRA and PRA are reliable, valid risk indicators for choking and pneumonia in adults with IDD. Precautions for mitigating choking and pneumonia risks can be applied selectively thus avoiding undue impacts on quality of life and unnecessary interventions for low risk individuals.

The Role of the Corpus Callosum in Pediatric Dysphagia: Preliminary Findings from a Diffusion Tensor Imaging Study in Children with Unilateral Spastic Cerebral Palsy.

The purpose of this study is to determine the relationship between the structural integrity of the corpus callosum (CC) and clinical feeding/swallowing performance in children with unilateral spastic cerebral palsy (USCP). Twenty children with USCP, (11 males, 5.11-17.6 yoa) were assessed via the Dysphagia Disorder Survey (DDS) and diffusion tensor imaging. Children were grouped into left hemisphere lesion (LHL; n = 13) and right hemisphere lesion (RHL; n = 7) groups. DTI variables analyzed for three CC regions (anterior, middle, posterior) were: fractional anisotropy (FA), radial diffusivity (RD), mean diffusivity (MD), and fibers count. Children with RHL presented with higher clinical dysphagia severity (p = 0.03). Six of seven children with RHL had lesions affecting periventricular/subcortical areas, and 8/13 children with LHL had lesions affecting the sensorimotor cortex. In the LHL group, as FA and fiber count of the anterior CC decreased and RD increased (all indicating reduced CC structural integrity), signs of dysphagia increased (r = -0.667, p = 0.013; r = -0.829, p ≤ 0.001; r = 0.594, p = 0.032, respectively). Reduced fiber count in the middle and posterior CC was also significantly associated with increased DDS scores (r = -0.762, p = 0.002; r = -0.739, p = 0.004, respectively). For the RHL group no significant correlations were observed. We provide preliminary evidence that corpus callosum integrity correlates with feeding/swallowing performance in children with USCP, especially when cortical sensorimotor areas of the left hemisphere are impacted. In this sample, CC integrity appeared to enable interhemispheric cortical plasticity for swallowing, but was not as critical when intrahemispheric connections were disrupted, as seen in the RHL group.

A telehealth approach to conducting clinical swallowing evaluations in children with cerebral palsy.

BACKGROUND: Accurate and timely evaluation of dysphagia in children with cerebral palsy (CP) is critical. For children with limited access to quality healthcare, telehealth is an option; however, its reliability needs to be investigated. AIM: To test the reliability of an asynchronous telehealth model for evaluating dysphagia in children with CP using a standardized clinical assessment. METHODS AND PROCEDURES: Nineteen children (age range 6.9-17.5) were assessed at three mealtimes via the Dysphagia Disorder Survey (DDS) by three clinicians (face-to-face evaluations). Mealtimes were video-recorded to allow asynchronous evaluations by a remote clinician who also completed approximately 1/3 of face-to-face evaluations. Agreement was tested on DDS variables and dysphagia severity. OUTCOMES AND RESULTS: Results revealed substantial to excellent agreement between face-to-face and remote assessments by the same rater (78-100%, KW=0.64-1) on all, but two variables (oral transport and oral pharyngeal swallow) and by different raters (69-89%, KW=0.6-0.86) on all but one variable (orienting). For dysphagia severity, intrarater agreement was excellent (100%, KW=1); interrater agreement was substantial (85%; KW=0.76). CONCLUSIONS AND IMPLICATIONS: Asynchronous clinical swallowing evaluations using standardized tools have acceptable levels of agreement with face-to-face evaluations, and can be an alternative for children with limited access to expert swallowing care.

Feasibility of implementing oral health guidelines in residential care settings: views of nursing staff and residential care workers.

PURPOSE: To determine the views of nurses and on the feasibility of implementing current evidence-based guidelines for oral care, examining barriers and facilitators to implementation. RESULTS: This mixed-methods study involved an online survey of 35 nurses and residential care workers, verified and expanded upon by one focus group of six residential care workers. Results reflected that nurses and residential care workers (a) have little or no training in recommended oral care techniques, and (b) lack access to the equipment and professional supports needed to provide adequate oral care. Basic oral care might be performed less than once per day in some settings and patients with problematic behaviours, dysphagia, or sensitivities associated with poor oral health might be less likely to receive oral care. While lack of time was highlighted as a barrier in the survey findings, focus group members considered that time should not be a barrier to prioritising oral care practices on a daily basis in residential care settings. CONCLUSION: There are several important discrepancies between the recommendations made in evidence-based guidelines for oral care and the implementation of such practices in residential care settings. Nursing and residential care staff considered adequate oral care to be feasible if access, funding and training barriers are removed and facilitators enhanced.

The dysphagia disorder survey: validation of an assessment for swallowing and feeding function in developmental disability.

Swallowing and feeding disorder (dysphagia) have high incidence and prevalence in children and adults with developmental disability. Standardized screening and clinical assessments are needed to identify and describe the disorder. The aim of this study was to describe the psychometric properties of the Dysphagia Disorder Survey (DDS), a screening and clinical assessment of swallowing and feeding function for eating and drinking developed specifically for this population. The statistical analysis was performed on a sample of 654 individuals (age range 8-82) with intellectual and developmental disability living in two residential settings in the United States that served somewhat different populations. The two samples had similar factor structures. Internal consistency of the DDS and subscales was confirmed using Chronbach's coefficient alpha. The DDS demonstrated convergent validity when compared to judgments of swallowing and feeding disorder severity made by clinical swallowing specialists. Discriminative validity for severity of disorder was tested by comparing the two samples. The results of the study suggest that the DDS is a reliable and valid test for identifying and describing swallowing and feeding disorder in children and adults with developmental disability.

Telepractice for pediatric Dysphagia: a case study.

A closed-ended intensive pediatric swallowing telepractice program was developed and piloted in one pediatric patient with Opitz BBB/G and Asperger's Syndromes, oropharyngeal dysphagia and aerophagia. The present study is a case report. Outcome variables included behavioral, swallowing and quality of life variables, and were assessed at baseline and at the end of the four-week program. Selective variables were also assessed at a follow-up family interview four weeks post program completion. Over the four-week intervention period, the patient demonstrated substantial improvements in: oral acceptance of eating-related objects and a variety of foods (behavioral variable), timing of voluntary saliva swallows and aerophagia levels (swallowing variables) and quality of life. Follow-up interview analysis showed that most skills were retained or improved one-month post intervention. This intensive telepractice program proved to be feasible and effective for this pediatric patient with dysphagia.

Understanding mealtime changes for adults with cerebral palsy and the implications for support services.

BACKGROUND: Changes in the swallowing capabilities of adults with cerebral palsy as they age may impact on their health, safety, and well-being. METHOD: Thirty-two adults with cerebral palsy aged between 30 and 69 years participated in in-depth interviews about their experiences of changes in their swallowing and related management of their mealtimes within the last two years. A constant comparative qualitative analysis of the interviews elucidated the changes they experienced. RESULTS: Changes included increased coughing and choking, digestive or gastro-oesophageal symptoms, diet modification, loss of independence with psychosocial consequences. Participants reported unsatisfactory collaboration with service providers over mealtime management decisions and interventions. CONCLUSIONS: Adults with cerebral palsy may experience gradual changes in their swallowing and mealtime capabilities from as early as 30 years of age. Regular collaborative assessment and involvement of all stakeholders in decisions are important to facilitate compliance with recommendations, ongoing safety, and optimal well-being.

Evidence-based interventions for breast and bottle feeding in the neonatal intensive care unit.

Breast and bottle-feeding are areas of concern in the neonatal intensive care unit (NICU). The clinical issues encompass the typically developing preterm infant, who requires special supports to develop the skills needed for successful oral feeding, and the preterm and term infants with dysphagia, who, when able, require specialized assessment and treatment strategies to facilitate the maturation of sucking behaviors and transition to oral feeding. Research is increasingly addressing the development from non-nutritive to nutritive sucking, maturation of typical and atypical nutritive sucking in young infants, as well as assessment strategies and treatment supports for emerging sucking and remediation of feeding or swallowing problems. There continue to be gaps in the available information. These gaps are filled by expert opinion and clinical experience. However, an increase of clinically relevant, databased information is promising. The primary goals of treatment in this population are to facilitate transition from tube to oral feeding and advance sucking skills sufficiently to support needs for nutrition and hydration as the infant grows. The purpose of this article is to review the recent research that has provided an evidence base for clinical practice. The discussion includes research and practice for the use of clinical and instrumental assessments, and for therapeutic interventions selected to prepare the infant for nipple feeding and to support the infant and improve sucking competencies during oral feeding.
