Interventions for oropharyngeal dysphagia in acute and critical care: a systematic review and meta-analysis

[Medical nutrition therapy in amyotrophic lateral sclerosis - Do we act or react? A case report and multidisciplinary review]

Introduction

Background: amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with a progressive course. The current prevalence is between 3 and 6 cases/100,000. Malnutrition is closely related to patient prognosis in ALS. The implications of this conditions have been that we should recommend patient care in a multidisciplinary unit. Case report: the case presented shows the evolution of a patient with ALS. The patient was referred to different clinical departments after neurological evaluation and her nutritional, functional and respiratory status were assessed. There was no nutritional deterioration at diagnosis; however, intake was below energy-protein requirements. The clinical evolution of the patient showed a decrease in muscle mass with preservation of weight and fat mass. "Aggressive" measures to control nutritional status such as gastrostomy were rejected in the initial stages of the disease, but had to be carried out after development of dysphagia and associated malnutrition. This situation of progressive morphofunctional deterioration and the development of disease-related complications made essential the participation of different health services and professionals in its control. Dicussion: the management of ALS in a multidisciplinary manner allows to improve the course of the disease and the quality of life of both the patients and their families. Patient follow-up is based on the adjustment and management of complications. The basis of the relationship with these patients includes maintaining an adequate communication with them and their families, and ensuring joint decision-making about their condition.

Rehabilitative intervention for successful decannulation in adult patients with acquired brain injury and tracheostomy: a systematic review

PURPOSE

Tracheostomy and dysphagia are independently associated with increased complications and poorer functional outcome after acquired brain injury (ABI). The aim of this study was to identify and evaluate rehabilitation to restore functional swallowing ability and respiratory capacity during tracheal tube weaning.

MATERIALS AND METHODS

The review was conducted according to PRISMA guidelines. Any study design with adult patients with ABI and tracheostomy was eligible. The primary outcome was decannulation.

RESULTS

A total of 2647 records were identified and eight papers included. Four studies investigated pharyngeal electrical stimulation (PES), two explored Facial Oral Tract Therapy (F.O.T.T.), one respiratory physiotherapy (RPT), and one study investigated external subglottic air flow (ESAF). Two RCTs found a significant difference between intervention and control on successful decannulation and readiness for decannulation in favour of PES. Time from rehabilitation admission and tracheostomy to decannulation was significantly reduced after implementing an F.O.T.T.-based protocol.

CONCLUSION

Four interventions were identified, PES, F.O.T.T., RPT, and ESAF, all aimed at increasing oropharyngeal sensory input through stimulation. Due to heterogeneity of interventions, designs and outcome measures, effect could not be estimated. This review highlights the limited research on rehabilitative interventions and thus the limited evidence to guide clinical rehabilitation.

Dysphagia Rehabilitation in Dysphagic Patients with Acute or Critical Illness: A Systematic Review and Meta-Analysis

Dysphagia or swallowing dysfunction is common in patients with acute or critical illness, and diverse methods of dysphagia rehabilitation are provided worldwide. We aimed to examine the efficacy of rehabilitation to treat dysphagia in patients with acute or critical illness. We searched PubMed, ICHUSHI, and Cochrane Central Register of Controlled Trials databases from inception to November 22, 2023 for relevant randomized controlled trials. We focused on dysphagic patients with acute or critical illness who were not orotracheally intubated. Our target intervention included conventional rehabilitation and nerve stimulation/neuromodulation techniques as dysphagia rehabilitation. Comparators were conventional or standard care or no dysphagia interventions. Primary outcomes included mortality, incidence of pneumonia during the study period, and health-related quality of life (HRQoL) scores within 90 days of hospital discharge. We pooled the data using a random-effects model, and classified the certainty of evidence based on the Grading of Recommendations, Assessment, Development, and Evaluation system. Nineteen randomized controlled trials involving 1,096 participants were included. Dysphagia rehabilitation was associated with a reduced incidence of pneumonia (risk ratio [RR], 0.66; 95% confidence interval [CI], 0.54-0.81; moderate certainty), but not with reduced mortality (RR, 0.92; 95% CI, 0.61-1.39; very low certainty) or improved HRQoL scores (mean difference, -0.20; 95% CI, -20.34 to 19.94; very low certainty). Based on the available moderate- or very low- quality evidence, while dysphagia rehabilitation had no impact on mortality or HRQoL, they might reduce the incidence of pneumonia in dysphagic patients with acute or critical illness.

Efficacy observation, complications and nursing of enteral nutrition suspension in patients with acute ischemic stroke

OBJECTIVE

This study focuses on exploring the efficacy observation, complications and nursing aspects of using enteral nutrition suspension in patients with acute ischemic stroke.

METHODS

This study retrospectively analyzed clinical data from 188 patients with acute ischemic stroke treated in the Neurology Department of our hospital from October 2022 to September 2023. Patients who received intermittent enteral nutrition and nursing interventions were included in the control group (n=96), while patients who received continuous enteral nutrition and nursing interventions were included in the treatment group (n=92). Relevant indicators data changes before and after treatment were recorded for each patient, along with the occurrence of complications in both groups, and statistical analysis was conducted.

RESULTS

The treatment group had fewer days in the ICU and total hospitalization days compared to the control group, with p < .05. Patients in the treatment group had higher levels of serum albumin and serum prealbumin than those in the control group, with p < .05. The occurrence of abdominal pain, diarrhea, constipation, bloating and acid reflux in the treatment group was lower than in the control group, with p < .05. There was no significant difference in the occurrence of adverse outcomes at discharge, death at discharge, cerebral hemorrhage, lung infection and gastrointestinal bleeding between the two groups (p > .05).

CONCLUSION

The application of enteral nutrition suspension in patients with acute ischemic stroke effectively provides the necessary nutrients, maintains nutritional balance, promotes tissue repair and recovery and reduces the length of hospital stay.

Interventions for Postextubation Dysphagia in Critically Ill Patients: A Systematic Review and Meta-analysis

OBJECTIVE

This review evaluates the efficacy and safety of dysphagia interventions for patients with prolonged endotracheal intubation (⩾48 h) in critical care units.

DATA SOURCES

We systematically searched PubMed, Cochrane Library, Medline, Embase, OVID, CINAHL, Wanfang (China), CNKI (China), and ProQuest Dissertations for studies published up to December 31, 2023.

STUDY SELECTION

Inclusion criteria encompassed randomized controlled trials (RCTs), quasi-randomized trials, and cohort studies comparing dysphagia rehabilitation - such as swallowing stimulation, swallowing and respiratory muscle exercise, and neuromuscular electrical stimulation - with standard care or no treatment. The primary outcomes assessed were dysphagia severity, time to resume oral intake, and incidence of aspiration and aspiration pneumonia.

DATA EXTRACTION

Detailed information on study design, setting, participant demographics, interventions, and outcomes was systematically extracted.

DATA SYNTHESIS

Our analysis included ten studies with a total of 1031 participants. The findings demonstrate a significant reduction in dysphagia severity, time to oral intake and the risk of aspiration pneumonia, and an improvement in quality of life among patients receiving swallowing therapy. However, no substantial difference was found in nutritional status. Limited data availability necessitated a descriptive presentation of outcomes like the risk of aspiration, ICU/hospital stay duration, pharyngeal/oral residue severity, and intervention-related adverse events.

CONCLUSION

The current evidence for the effectiveness of dysphagia interventions in critically ill patients with prolonged endotracheal intubation is limited. There is a pressing need for future research, particularly high-quality RCTs employing standardized outcome measures, to substantiate these findings.

Implementing flexible endoscopic evaluation of swallow screening within annual cancer surveillance appointments to monitor for late-stage radiation-induced dysphagia: A feasibility study

BACKGROUND

Late-stage progressive decline of swallowing function after radiotherapy for head and neck cancer (HNC) is often difficult to monitor. This study examined the feasibility and clinical outcomes of speech-language pathology implementing flexible endoscopic evaluation of swallow (FEES) screening during annual cancer surveillance visits to monitor late-stage swallowing function.

METHODS

Patients >2 years post treatment who attended routine oncological visits underwent FEES screening. Feasibility (service data, stakeholder survey) and swallowing outcomes (oral intake, secretions, internal lymphedema, penetration-aspiration, and residue) were collected.

RESULTS

Screening was completed with 70% (50/71) of eligible patients. Medical staff and speech-language pathologists indicated the protocol was worthwhile and achievable to incorporate into practice. Almost all patients were willing to complete the protocol annually. FEES outcomes identified 84% with dysphagia versus only 26% self-reported dysphagia.

CONCLUSION

Findings indicate FEES screening incorporated into annual oncological reviews is feasible and effective at monitoring late-stage swallowing function following HNC.

Management of swallowing disorders in ICU patients - A multinational expert opinion

BACKGROUND

Dysphagia is common in intensive care unit (ICU) patients, yet it remains underrecognized and often unmanaged despite being associated with life-threatening complications, prolonged ICU stays and hospitalization.

PURPOSE

To propose an expert opinion for the diagnosis and management of dysphagia developed from evidence-based clinical recommendations and practitioner insights.

METHODS

A multinational group of dysphagia and critical care experts conducted a literature review using a modified ACCORD methodology. Based on a fusion of the available evidence and the panel's clinical experience, an expert opinion on best practice management was developed.

RESULTS

The panel recommends adopting clinical algorithms intended to promote standardized, high-quality care that triggers timely systematic dysphagia screening, assessment, and treatment of extubated and tracheostomized patients in the ICU.

CONCLUSIONS

Given the lack of robust scientific evidence, two clinical management algorithms are proposed for use by multidisciplinary teams to improve early systematic detection and effective management of dysphagia in ICU patients. Additionally, emerging therapeutic options such as neurostimulation have the potential to improve the quality of ICU dysphagia care.

Does ICU admission dysphagia independently contribute to delirium risk in ischemic stroke patients? Results from a cohort study

BACKGROUND

Delirium is prevalent in ischemic stroke patients, particularly those in the intensive care unit (ICU), and it poses a significant burden on patients and caregivers, leading to increased mortality rates, prolonged hospital stays, and impaired cognitive function. Dysphagia, a common symptom in critically ill patients with ischemic stroke, further complicates their condition. However, the association between dysphagia and delirium in this context remains unclear. The objective of this study was to investigate the correlation between dysphagia and delirium in ICU patients with ischemic stroke.

METHODS

A retrospective analysis was conducted on adult patients diagnosed with ischemic stroke at a medical center in Boston. Ischemic stroke cases were identified using the ninth and tenth revisions of the International Classification of Diseases. Dysphagia was defined as a positive bedside swallowing screen performed by medical staff on the day of ICU admission, while delirium was assessed using the ICU Confusion Assessment Method and review of nursing notes. Logistic regression models were used to explore the association between dysphagia and delirium. Causal mediation analysis was employed to identify potential mediating variables.

RESULTS

The study comprised 1838 participants, with a median age of approximately 70 years, and 50.5% were female. Among the total study population, the prevalence of delirium was 43.4%, with a higher prevalence observed in the dysphagia group (60.7% vs. 40.8%, p < 0.001) compared to the non-dysphagia group. After adjusting for confounding factors including age, sex, race, dementia, depression, sedative medications, history of falls, visual or hearing deficit, sequential organ failure score, and Glasgow coma score, multifactorial logistic regression analysis demonstrated a significant association between dysphagia and an increased likelihood of delirium (odds ratio [OR]: 1.48; 95% confidence interval [CI]: 1.07-2.05; p = 0.018; E-value = 1.73). Causal mediation analysis revealed that serum albumin levels partially mediated the association between dysphagia and delirium in critically ill patients with ischemic stroke (average causal mediated effect [ACME]: 0.02, 95% CI: 0.01 to 0.03; p < 0.001).

CONCLUSION

ICU admission dysphagia may independently contribute to the risk of delirium in patients with ischemic stroke. Early identification and intervention in ischemic stroke patients with dysphagia may help mitigate the risk of delirium and improve patient prognosis.

Dysphagia in adult intensive care patients: Results of a prospective, multicentre binational point prevalence study

BACKGROUND

Dysphagia occurs in intensive care unit (ICU) patients. However, there is a lack of epidemiological data on the prevalence of dysphagia in adult ICU patients.

OBJECTIVES

The objective of this study was to describe the prevalence of dysphagia in nonintubated adult patients in the ICU.

METHODS

A prospective, multicentre, binational, cross-sectional point prevalence study was conducted in 44 adult ICUs in Australia and New Zealand. Data were collected in June 2019 on documentation of dysphagia, oral intake, and ICU guidelines and training. Descriptive statistics were used to report demographic, admission, and swallowing data. Continuous variables are reported as means and standard deviations (SDs). Precisions of estimates were reported as 95% confidence intervals (CIs).

RESULTS

Of the 451 eligible participants, 36 (7.9%) were documented as having dysphagia on the study day. In the dysphagia cohort, the mean age was 60.3 years (SD: 16.37) vs 59.6 years (SD: 17.1) and almost two-thirds were female (61.1% vs 40.1%). The most common admission source for those patients with dysphagia were from the emergency department (14/36, 38.9%), and seven of 36 (19.4%) had a primary diagnosis of trauma (odds ratio: 3.10, 95% CI 1.25 - 7.66). There were no statistical differences in Acute Physiology and Chronic Health Evaluation (APACHE II) scores between those with and without a dysphagia diagnosis. Patients with dysphagia were more likely to have a lower mean body weight of 73.3 kg vs 82.1 kg than patients not documented as having dysphagia (95% CI of mean difference: 0.43 to 17.07) and require respiratory support (odds ratio: 2.12, 95% 1.06 to 4.25). The majority of patients with dysphagia were prescribed modified food and fluids in the ICU. Less than half of ICUs surveyed reported unit-level guidelines, resources, or training for management of dysphagia.

CONCLUSIONS

The prevalence of documented dysphagia in adult ICU nonintubated patients was 7.9%. There were a higher proportion of females with dysphagia than previously reported. Approximately two-thirds of patients with dysphagia were prescribed oral intake, and the majority were receiving texture-modified food and fluids. Dysphagia management protocols, resources, and training are lacking across Australian and New Zealand ICUs.

FT-GAT: Graph neural network for predicting spontaneous breathing trial success in patients with mechanical ventilation

BACKGROUND AND OBJECTIVES

Intensive care unit (ICU) physicians perform weaning procedures considering complex clinical situations and weaning protocols; however, liberating critical patients from mechanical ventilation (MV) remains challenging. Therefore, this study aims to aid physicians in deciding the early liberation of patients from MV by developing an artificial intelligence model that predicts the success of spontaneous breathing trials (SBT).

METHODS

We retrospectively collected data of 652 critical patients (SBT success: 641, SBT failure: 400) who received MV at the Chungbuk National University Hospital (CBNUH) ICU from July 2020 to July 2022, including mixed and trauma ICUs. Patients underwent SBTs according to the CBNUH weaning protocol or physician's decision, and SBT success was defined as extubation performed by the physician on the SBT day. Additionally, our dataset comprised 11 numerical and 2 categorical features that can be obtained for any ICU patient, such as vital signs and MV setting values. To predict SBT success, we analyzed tabular data using a graph neural network-based approach. Specifically, the graph structure was designed considering feature correlation, and a novel deep learning model, called feature tokenizer graph attention network (FT-GAT), was developed for graph analysis. FT-GAT transforms the input features into high-dimensional embeddings and analyzes the graph via the attention mechanism.

RESULTS

The quantitative evaluation results indicated that FT-GAT outperformed conventional models and clinical indicators by achieving the following model performance (AUROC): FT-GAT (0.80), conventional models (0.69-0.79), and clinical indicators (0.65-0.66) CONCLUSIONS: Through timely detection critical patients who can succeed in SBTs, FT-GAT can help prevent long-term use of MV and potentially lead to improvement in patient outcomes.

Associations Between Dysphagia and Adverse Health Outcomes in Older Adults with Dementia in Intensive Care Units: A Retrospective Cohort Study

BACKGROUND

Dysphagia is common in elderly patients with dementia and is one of the common clinical geriatric syndromes. It imposes a heavy burden on patients and their caregivers and is becoming an important public health problem. This study examined the association between dysphagia in older dementia patients in the ICU and the subsequent adverse health outcomes they experience.

PATIENTS AND METHODS

A retrospective analysis of adults (≥65 years) with dementia in ICUs of a Boston tertiary academic medical center was conducted. Using the International Classification of Diseases' Ninth and Tenth Revisions, dementia patients were identified. The study cohort comprised 1009 patients, median age 84.82 years, 56.6% female, predominantly White (72.9%). Patients were grouped based on swallowing function: dysphagia (n=282) and no-dysphagia (n=727). Dysphagia was identified via positive bedside swallowing screening. Primary outcomes were 90- and 180-day mortality, secondary outcomes included aspiration pneumonia, pressure injury, and delirium. Cohort characteristics were compared using the Wilcoxon rank-sum and chi-square tests. Dysphagia and outcomes correlations were examined via Kaplan-Meier survival analysis, Cox proportional-hazards regression models, logistic regression models, and subgroup analysis.

RESULTS

After adjusting for covariates, the results from multivariate Cox proportional-hazards regression indicated that dysphagia was significantly associated with increased 90-day (HR=1.36, 95% CI=1.07-1.73, E-value=1.78) and 180-day (HR=1.47, 95% CI=1.18-1.82, E-value=1.94) mortality; the multifactorial logistic regression results indicated that dysphagia was associated with significant increases in pressure injury (OR=1.58, 95% CI=1.11-2.23, E-value=1.83) and aspiration pneumonia occurrence (OR=4.04, 95% CI=2.72-6.01, E-value=7.54), but was not significantly associated with delirium prevalence (OR=1.27, 95% CI=0.93-1.74).

CONCLUSION

Dysphagia is likely to increase the risk of adverse health outcomes in older adults with dementia in ICU, and these adverse outcomes mostly include 90- and 180-day mortality, aspiration pneumonia, and pressure injury.

Effects of a swallowing and oral-care program on resuming oral feeding and reducing pneumonia in patients following endotracheal extubation: a randomized, open-label, controlled trial

BACKGROUND

The resumption of oral feeding and free from pneumonia are important therapeutic goals for critically ill patients who have been successfully extubated after prolonged (≥ 48 h) endotracheal intubation. We aimed to examine whether a swallowing and oral-care (SOC) program provided to critically ill patients extubated from prolonged mechanical ventilation improves their oral-feeding resumption and reduces 30-day pneumonia incidence.

METHODS

In this randomized, open-label, controlled trial, participants were consecutively enrolled and randomized to receive the SOC program or usual care. The interventions comprised three protocols: oral-motor exercise, sensory stimulation and lubrication, and safe-swallowing education. Beginning on the day following patient extubation, an SOC nurse provided the three-protocol care for seven consecutive days or until death or hospital discharge. With independent outcome assessors, oral-feeding resumption (yes, no) corresponded to level 6 or level 7 on the Functional Oral Intake Scale (censored seven days postextubation) along with radiographically documented pneumonia (yes, no; censored 30 days postextubation), abstracted from participants' electronic medical records were coded.

RESULTS

We analyzed 145 randomized participants (SOC group = 72, control group = 73). The SOC group received, on average, 6.2 days of intervention (14.8 min daily) with no reported adverse events. By day 7, 37/72 (51.4%) of the SOC participants had resumed oral feeding vs. 24/73 (32.9%) of the control participants. Pneumonia occurred in 11/72 (15.3%) of the SOC participants and in 26/73 (35.6%) of the control participants. Independent of age and intubation longer than 6 days, SOC participants were likelier than their control counterparts to resume oral feeding (adjusted hazard ratio, 2.35; 95% CI 1.38-4.01) and had lower odds of developing pneumonia (adjusted odds ratio, 0.28; 95% CI 0.12-0.65).

CONCLUSIONS

The SOC program effectively improved patients' odds that oral feeding would resume and the 30-day pneumonia incidence would decline. The program might advance dysphagia care provided to critically ill patients extubated from prolonged mechanical ventilation.

Dysphagia in intensive care, a real problem: analysis of risk factors

AIMS

To identify risk factors present in patients with dysphagia in a population of critically ill patients.

METHODS

Case series of a cohort of patients recruited in the intensive care unit (ICU) until hospital discharge. Patients who gave consent and met the inclusion criteria were recruited. The Volume-Viscosity clinical examination method was used for the screening of dysphagia. An uni- and bivariate statistical analysis was performed using odds ratio (OR) to detect risk factors for dysphagia.

OUTCOMES

103 patients were recruited from 401 possible. The mean age was 59,33 ± 13,23, men represented 76,7%. The severity of the sample was: APACHE II (12,74 ± 6,17) and Charlson (2,98 ± 3,31). 45,6% of patients showed dysphagia, obtaining significant OR values (p < 0,050) for the development of dysphagia: older age, neurological antecedents, COVID19, long stay in ICU and hospitalization, and the presence of tracheotomy. COVID19 patients represented 46,6% of the sample, so an analysis of this subgroup was performed, showing similar results, with a Charlson risk (OR:4,65; 95% CI:1,31-16,47; p = 0,014) and a hospital stay (OR: 8,50; 95%CI: 2,20-32,83; p < 0,001) On discharge from the ICU, 37,9% of the population still had dysphagia; 12,6% maintained this problem at hospital discharge.

CONCLUSIONS

Almost half of our patients developed dysphagia. Clinical severity and the presence of tracheotomy were risk factors. We observed in patients with dysphagia a longer stay in both ICU and hospitalization.

Perspectives on speech and language pathology practices and service provision in adult critical care settings in Ireland and international settings: A cross-sectional survey

PURPOSE

Patients admitted to critical care (CC) are at risk of impaired swallowing and communication function. Speech-language pathologists (SLPs) play an important role in this context. In Ireland and internationally speech-language pathology CC guidelines are lacking, with possible variations in practice. To compare clinical practices in dysphagia, communication and tracheostomy management among SLPs working in adult CC units in Ireland and internationally, and explore their perspectives on training, skills and resources.

METHOD

Participants were SLPs working in CC. An international online survey sought information on (i) SLP workforce demographics and staffing levels, (ii) current dysphagia and communication assessment and management practices, (iii) practices and perspectives on training, skills and resources.

RESULT

366 responses were received across 29 countries. 18.03% (66/366) of these respondents worked in Ireland. Findings showed similarities and differences in practices. Total CC SLP whole-time equivalent (WTE) at each staff grade was lower (mean difference: -0.21 to -0.65 WTE p <.001) than desired for optimal service delivery. Negative effects of under-staffing were reported. Recommendations that all tracheostomised patients receive SLP input was unmet in 66% (220/334) of services.

CONCLUSION

SLP input in CC is limited in terms of dedicated posts, multidisciplinary team (MDT) involvement, consistent management approaches and training opportunities internationally. Implications of findings are discussed.

Oxygen therapy alternatives in COVID-19: From classical to nanomedicine

Around 10-15% of COVID-19 patients affected by the Delta and the Omicron variants exhibit acute respiratory insufficiency and require intensive care unit admission to receive advanced respiratory support. However, the current ventilation methods display several limitations, including lung injury, dysphagia, respiratory muscle atrophy, and hemorrhage. Furthermore, most of the ventilatory techniques currently offered require highly trained professionals and oxygen cylinders, which may attain short supply owing to the high demand and misuse. Therefore, the search for new alternatives for oxygen therapeutics has become extremely important for maintaining gas exchange in patients affected by COVID-19. This review highlights and suggest new alternatives based on micro and nanostructures capable of supplying oxygen and/or enabling hematosis during moderate or acute COVID-19 cases.

Exploration of treatment methods for patients with post-stroke dysphagia: a network meta-analysis

To compare the effects of various therapies in patients with post-stroke dysphagia.

DATA SOURCES

We searched databases between January 1980 and 2022.

STUDY ELIGIBILITY CRITERIA

Randomized controlled trials (RCTs) on therapy for dysphagia after stroke.

STUDY APPRAISAL AND SYNTHESIS METHODS

The outcomes were improvement in dysphagia, case fatality, and chest infection or pneumonia, reported as OR (odd ratio), 95% CrI (confidence interval), and SUCRA (the surface under the cumulative ranking curve analysis) score. Forty-two randomized controlled trials (2,993 patients, seven therapies, and one control) were included. In the improvement of dysphagia analysis, the following therapies were superior to the control: Acupuncture, behavioral interventions, drug therapy, neuromuscular electrical stimulation (NMES) and pharyngeal electrical stimulation (PES). In the case fatality analysis, OR and 95% CrI indicated none of the therapies were superior to the control. In the chest infection or pneumonia analysis, OR values showed that no therapy was superior to the control. Our Network Meta-analysis suggests that commonly used therapies for dysphagia after stroke have equal efficacies.

A Predictive Model for Dysphagia after Ventilator Liberation in Severe Pneumonia Patients Receiving Tracheostomy: A Single-Center, Observational Study

The main purpose of this study was to develop a model predictive of dysphagia in hospital survivors with severe pneumonia who underwent tracheostomy during their hospital stay. The present study included 175 patients (72% male; mean age, 71.3 years) over 5 years. None of these patients had a history of deglutition disorder before hospital admission. Binary logistic regression analysis was performed to identify factors predicting dysphagia at hospital discharge. Dysphagia scores were calculated from β-coefficients and by assigning points to variables. Of the enrolled patients, 105 (60%) had dysphagia at hospital discharge. Factors prognostic of dysphagia at hospital discharge included being underweight (body mass index < 18.5 kg/m2), non-participation in a dysphagia therapy program, mechanical ventilation ≥ 15 days, age ≥ 74 years, and chronic neurologic diseases. Underweight and non-participation in a dysphagia therapy program were assigned +2 points and the other factors were assigned +1 point. Dysphagia scores showed acceptable discrimination (area under the receiver operating characteristic curve for dysphagia 0.819, 95% confidence interval: 0.754−0.873, p < 0.001) and calibration (Hosmer−Lemeshow chi-square = 9.585, with df 7 and p = 0.213). The developed dysphagia score was predictive of deglutition disorder at hospital discharge in tracheostomized patients with severe pneumonia.

Dietary Habits, Food Product Selection Attributes, Nutritional Status, and Depression in Middle-Aged and Older Adults with Dysphagia

Dysphagia, which increases the risk of malnutrition and depression, is an important health concern. A total of 304 people aged 50 years or above (148 subjects with dysphagia and 156 non-dysphagia subjects) were recruited for this survey of dietary habits, meal product selection attributes, nutritional status, and depression. For group comparisons, chi-square tests were performed. Exploratory factor analysis was conducted for the meal product selection attributes. Correlation analyses were performed to investigate links between EAT-10 (The 10-item Eating Assessment Tool), nutrition (Nutrition Quotient/Nutrition Quotient for the Elderly, NQ/NQ-E) and depression (The Short-Form Geriatric Depression Scale for Koreans, SGDS-K). Logistic regression analysis was performed to investigate links between EAT-10, nutritional status, and depressive status. Finally, a correlation analysis and logistic regression analysis of nutritional status, depression status, and some dietary factors were performed, targeting only the responses of the dysphagia patients. The average ages were 73.79 years in the dysphagia group and 70.15 years in the non-dysphagia group, and the total average age was 71.88 years. The overall age range was 50 to 92 years. Dysphagia (EAT-10) had significant effects on malnutrition (β = 0.037, OR = 1.095) and depression (β = 0.090, OR = 1.095) (p < 0.001). There was a significant correlation between SGDS-K, needing help with meals, and the amount of food consumed at mealtimes (p < 0.01). The correlation coefficient between SGDS-K and the need for help with meals was 0.474. Dietary factors that affected depression in dysphagia patients were the increase in the need for meal assistance (β = 1.241, OR = 3.460, p < 0.001) and the amount of food eaten at mealtimes (β = −0.494, OR = 0.702, p < 0.05). Dysphagia can increase the risk of depression and malnutrition. To reduce depression in dysphagia patients, it is necessary to develop meal products that address dietary discomfort among patients with dysphagia.

Association Between Early Speech-Language Pathology Consultation and Pneumonia After Cardiac Surgery

PURPOSE

Patients undergoing cardiac surgery are reported to be at higher risk for oropharyngeal dysphagia and aspiration, which may predispose them to respiratory complications such as pneumonia. Speech-language pathology consultation facilitates early identification of swallowing difficulties providing appropriate and timely interventions during the postoperative period. This study explores the association between pneumonia and timing of speech-language pathology order entry and evaluation following cardiac surgery.

METHOD

A retrospective study was performed on adults who underwent cardiac surgery in a tertiary care center, from July 2016 through December 2019. Patients with preexisting tracheostomy upon admission for cardiac surgery were excluded. The medical records of patients who had speech-language pathology consultation orders for swallowing concerns were analyzed in order to compare the timing of speech-language pathology order entry, completion of speech-language pathology evaluation, and incidence of pneumonia during hospitalization following cardiac surgery.

RESULTS

During the study period, 3,168 patients underwent cardiac surgery, of which 2,864 patients met the inclusion criteria. Speech-language pathology was ordered for 473 cases (16.5%), and clinical swallow evaluation (CSE) was completed by speech-language pathology in 419 patients (88.6%), of which 309 patients were suspected to have dysphagia (73.7%). Among the 2,391 patients without speech-language pathology consultation, pneumonia was reported in 34 patients (1.42%). Pneumonia was reported in 53 patients in the speech-language pathology cohort, of which 43 patients (13.9%) were suspected to have dysphagia. Patients with pneumonia had significantly longer median time (20.0 hr, range: 4.9-26.7) from speech-language pathology orders to completion of CSE, compared to those without pneumonia (13.2 hr, range: 3.2-22.4, p = .025). There was no significant difference in the median time from extubation to speech-language pathology consultation order time in patients with pneumonia versus those without pneumonia. Patients with pneumonia were observed to have prolonged, although not statistically significant, median time from extubation to CSE (70.4 hr, range: 21.2-215) compared to those without pneumonia (42.2 hr, range: 19.5-105.8, p = .066).

CONCLUSIONS

Patients without pneumonia in the postoperative period were observed to have shorter median time from extubation to speech-language pathology evaluation. Future studies are needed to further understand the impact of early speech-language pathology consultation and incidence of pneumonia in this population.

Frequency, associated factors, and associated outcomes of dysphagia following sepsis

BACKGROUND

Identifying dysphagia as a potential complication of sepsis may improve swallowing function and survival while decreasing hospital length of stay.

OBJECTIVES

Our goal was to determine the frequency of dysphagia in sepsis survivors on the 7th day after admission, as well as their associated factors and outcomes.

METHODS

This single-centre, retrospective, observational study analysed data from sepsis survivors admitted to Okayama Saiseikai General Hospital from 2018 to 2019. Participants with sepsis were assigned to one of two study groups based on the presence or absence of dysphagia using the criterion of Functional Oral Intake Scale score <5 on the 7th day after admission. We used multivariate logistic regression to determine factors independently associated with dysphagia on the 7th day after admission. Multivariate logistic regression was also used to determine associations between groups and outcomes, including dysphagia on hospital discharge, direct discharge home (discharge of patients directly to their home), and total dependency (Barthel Index score ≤20) on hospital discharge.

RESULTS

One hundred one patients met the study inclusion criteria, 55 with dysphagia and 46 without dysphagia. Fasting period (adjusted odds ratio [AOR]: 1.31, 95% confidence interval [CI]: 1.07-1.59) and enteral tube feeding (AOR: 8.56, 95% CI: 1.95-37.5) were independently associated with the presence of dysphagia on the 7th day after admission. Dysphagia on the 7th day after admission was associated with dysphagia on hospital discharge (AOR: 46.0, 95%, CI: 7.90-268.3), a lower chance of direct discharge home (AOR: 0.03, 95% CI: 0.01-0.15), and a higher incidence of total dependency (AOR: 9.30, 95% CI: 2.68-32.2).

CONCLUSIONS

We found that dysphagia was commonly encountered post sepsis. Fasting period and enteral tube feeding were independently associated with dysphagia on the 7th day after admission. Dysphagia on the 7th day after admission was also associated with dysphagia on hospital discharge, nondirect discharge home, and dependency in activities of daily living at the time of hospital discharge.

Association between timing of speech and language therapy initiation and outcomes among post-extubation dysphagia patients: a multicenter retrospective cohort study

Background

Post-extubation dysphagia (PED) is recognized as a common complication in the intensive care unit (ICU). Speech and language therapy (SLT) can potentially help improve PED; however, the impact of the timing of SLT initiation on persistent PED has not been well investigated. This study aimed to examine the timing of SLT initiation and its effect on patient outcomes after extubation in the ICU.

Methods

We conducted this multicenter, retrospective, cohort study, collecting data from eight ICUs in Japan. Patients aged ≥ 20 years with orotracheal intubation and mechanical ventilation for longer than 48 h, and those who received SLT due to PED, defined as patients with modified water swallowing test scores of 3 or lower, were included. The primary outcome was dysphagia at hospital discharge, defined as functional oral intake scale score < 5 or death after extubation. Secondary outcomes included dysphagia or death at the seventh, 14th, or 28th day after extubation, aspiration pneumonia, and in-hospital mortality. Associations between the timing of SLT initiation and outcomes were determined using multivariable logistic regression.

Results

A total of 272 patients were included. Of them, 82 (30.1%) patients exhibited dysphagia or death at hospital discharge, and their time spans from extubation to SLT initiation were 1.0 days. The primary outcome revealed that every day of delay in SLT initiation post-extubation was associated with dysphagia or death at hospital discharge (adjusted odds ratio (AOR), 1.09; 95% CI, 1.02–1.18). Similarly, secondary outcomes showed associations between this per day delay in SLT initiation and dysphagia or death at the seventh day (AOR, 1.28; 95% CI, 1.05–1.55), 14th day (AOR, 1.34; 95% CI, 1.13–1.58), or 28th day (AOR, 1.21; 95% CI, 1.07–1.36) after extubation and occurrence of aspiration pneumonia (AOR, 1.09; 95% CI, 1.02–1.17), while per day delay in post-extubation SLT initiation did not affect in-hospital mortality (AOR, 1.04; 95% CI, 0.97–1.12).

Conclusions

Delayed initiation of SLT in PED patients was associated with persistent dysphagia or death. Early initiation of SLT may prevent this complication post-extubation. A randomized controlled study is needed to validate these results.

Speech-language pathology approaches to neurorehabilitation in acute care during COVID-19: Capitalizing on neuroplasticity

Neurologic manifestations associated with a coronavirus disease 2019 (COVID‐19) diagnosis are common and often occur in severe and critically ill patients. In these patients, the neurologic symptoms are confounded by critical care conditions, such as acute respiratory distress syndrome (ARDS). Patients with dual diagnoses of COVID‐19 and neurologic changes such as myopathy, polyneuropathy, and stroke are likely at a higher risk of experiencing deficits with swallowing, communication, and/or cognition. Speech‐language pathologists are an integral part of both the critical care and neurologic disorders multi‐disciplinary teams, offering valuable contributions in the evaluation, treatment, and management of these areas. Patients in intensive care units (ICUs) who require mechanical ventilation often experience difficulty with communication and benefit from early speech‐language pathology intervention to identify the most efficient communication methods with the medical team and caregivers. Moreover, patients with neurologic manifestations may present with cognitive‐linguistic impairments such as aphasia, thereby increasing the need for communication‐based interventions. Difficulties with voice and swallowing after extubation are common, often requiring frequent treatment sessions, possibly persisting beyond ICU discharge. After leaving the ICU, patients with COVID‐19 often experience physical, cognitive, and mental health impairments collectively called post‐intensive care syndrome. This is often a lengthy road as they progress toward full recovery, requiring continued speech‐language pathology treatment after hospital discharge, capitalizing on the principles of neuroplasticity.

The care needs of persons with oropharyngeal dysphagia and their informal caregivers: A scoping review

INTRODUCTION

Besides affecting physical health, Oropharyngeal Dysphagia (OD) entails limitations in daily activities and social participation for both patients and their informal caregivers. The identification of OD-related needs is crucial for designing appropriate person-centered interventions.

AIMS

To explore and map the literature investigating the care needs related to OD management of adult persons with OD and their informal caregivers during the last 20 years.

METHODS

A scoping review was conducted and reported following PRISMA guidelines. Five electronic databases and reference lists of eligible publications were searched for original works in English or Italian, published between January 2000 and February 2021. Two independent raters assessed studies' eligibility and extracted data; a third rater resolved disagreements. Extracted care needs were analyzed using a Best fit framework synthesis approach.

RESULTS

Out of 2,534 records preliminarily identified, 15 studies were included in the review and 266 care needs were extracted. All studies were conducted in Western countries. Research methods primarily consisted of qualitative interviews and focus groups (14 studies, 93.3%); head and neck cancer was the most frequent cause of patients' dysphagia (8 studies, 53.3%); caregivers' perspective was seldom investigated (5 studies, 33.3%). Both patients and caregivers primarily reported social (N = 77; 28.9%) and practical (N = 67; 25.2%) needs, followed by informational (N = 55; 20.7%) and psychological (N = 54; 20.3%) ones. Only patients reported physical needs (N = 13; 4.9%), while spiritual needs were not cited.

CONCLUSIONS

The recurrence of personal and social needs besides physical ones highlighted the manifold impact of OD on patients' and caregivers' lives. Larger and more focused studies are required in order to design tools and interventions tailored to patients' and caregivers' needs.

The addition of respiratory muscle strength training to facilitate swallow and pulmonary rehabilitation following massive tissue loss and severe deconditioning: A case series

INTRODUCTION

Impaired respiratory and swallow function in patients with intensive care unit-acquired deconditioning, such as associated with massive tissue loss, is not uncommon and can require prolonged rehabilitation.

AIM

The aim of the study was to examine the effect of combined inspiratory and expiratory respiratory muscle strength training (RMST) on respiratory and swallow function in two critical care patients with marked deconditioning after massive tissue loss.

METHODS

Case 1 was a 19-year-old male patient with 80% body surface area burns; case 2 was a 45-year-old man with group A streptococcus myositis necessitating quadruple amputation. Both required prolonged intensive care and mechanical ventilation. Both received routine intensive pulmonary and swallow rehabilitation before the trial; however, chronic aspiration and poor secretion clearance remained. At 25 and 26 weeks after initial injury, RMST was performed using EMST150 (expiratory) and Threshold IMT (inspiratory) devices, respectively. At baseline and throughout treatment, data collected included peak expiratory flow (PEF), anthropometry measures, aspiration risk (Penetration-Aspiration Scale [PAS]), pharyngeal clearance (Yale Pharyngeal Residue Scale), secretions (New Zealand Secretion Scale [NZSS]), and functional diet (Functional Oral Intake Scale [FOIS]) via endoscopy.

RESULTS/DISCUSSION

At baseline, the PEF score of case 1 was 41% (predicted age-height norm) and the PEF score of case 2 was 14%, indicating severe expiratory compromise. Both had extreme energy requirements (3300 kcal/day; 3500 kcal/day). The baseline swallowing scores of case 1 and 2 were as follows: PAS, 8 and 8; Yale, 9 and 10; NZSS, 4 and 7; and FOIS, 1 and 1, respectively, indicating profound dysphagia. At week 3 of 7 of RMST, swallow function improved to allow both to commence oral intake, followed by tracheostomy decannulation. At weeks 10 and 11, full dysphagia resolution was achieved (FOIS = 7; PAS = 1, Yale = 2, NZSS = 0), with PEF at 70% and 48% predicted respectively. Both patients continued RMST, and at discharge from the acute facility, PEF was 84% and 80% predicted respectively.

CONCLUSION

The addition of RMST assisted swallow and pulmonary rehabilitation in both cases and was clinically viable to deliver. Controlled validation trials are now required.

Gastrointestinal motility disorders in neurologic disease

The extrinsic and autonomic nervous system intricately controls the major functions of the gastrointestinal tract through the enteric nervous system; these include motor, secretory, sensory, storage, and excretory functions. Disorders of the nervous system affecting gastrointestinal tract function manifest primarily as abnormalities in motor (rather than secretory) functions. Common gastrointestinal symptoms in neurologic disorders include sialorrhea, dysphagia, gastroparesis, intestinal pseudo-obstruction, constipation, diarrhea, and fecal incontinence. Diseases of the entire neural axis ranging from the cerebral hemispheres to the peripheral autonomic nerves can result in gastrointestinal motility disorders. The most common neurologic diseases affecting gastrointestinal function are stroke, parkinsonism, multiple sclerosis, and diabetic neuropathy. Diagnosis involves identification of the neurologic disease and its distribution, and documentation of segmental gut dysfunction, typically using noninvasive imaging, transit measurements, or intraluminal measurements of pressure activity and coordination of motility. Apart from treatment of the underlying neurologic disease, management focuses on restoration of normal hydration and nutrition and pharmacologic treatment of the gut neuromuscular disorder.

Best Practice Recommendations for Stroke Patients with Dysphagia: A Delphi-Based Consensus Study of Experts in Turkey-Part II: Rehabilitation

Dysphagia is one of the most common and important complications of stroke. It is an independent marker of poor outcome following acute stroke and it continues to be effective for many years. This consensus-based guideline is not only a good address to clinical questions in practice for the clinical management of dysphagia including management, diagnosis, follow-up, and rehabilitation methods, but also includes detailed algorithms for these topics. The recommendation paper has been written by a multidisciplinary team and offers 117 recommendations for stroke patients with dysphagia. While focusing on management principles, diagnosis, and follow-up in the 1st part (45 items), rehabilitation details were evaluated in the 2nd part (72 items).

Effect of Mucosal Brushing on the Serum Levels of C-Reactive Protein for Patients Hospitalized with Acute Symptoms

This study was based in a hospital setting. Patients with acute symptoms face a life-threatening crisis and often have systemic complications during the convalescence stage. During the acute stage, oral function does not work and oral hygiene status deteriorates. A gauze or sponge brush is generally used to wipe the oral cavity; however, this process does not clean the oral cavity enough. Effective oral care requires better methods. Patients participating in this study were all hospitalized by ambulance and with acute symptoms. During the convalescence stage, patients were assigned application of mucosal brushing or wiping by gauze or sponge brush by order of hospitalization. The effects were evaluated by the number of bacteria on the tongue surface, serum C-reactive protein (CRP) and body temperature. Changes in bacterial count, body temperature, and CRP were effectively reduced in the mucosal brushing group compared to the wiping by gauze or sponge brush group. Based on mixed effect modeling, the coefficient of mucosal brushing for CRP was −2.296 and for body temperature was −0.067 and statistically significant. This simple method can effectively prevent systemic complication of inpatients with deteriorated oral conditions. This method may also be effective for the elderly in nursing homes or perioperative oral-care management.
