Post-extubation dysphagia incidence in critically ill patients: A systematic review and meta-analysis

Postextubation dysphagia management in Danish intensive care units: A national survey

BACKGROUND

Postextubation dysphagia (PED) is a common complication to endotracheal intubation in critically ill patients and may lead to pneumonia, prolonged ventilation, longer hospital stays, and increased mortality. Recognizing dysphagia is paramount to preventing adverse events. The aim of this study was to describe PED management by investigating practice in Danish intensive care units (ICUs) focusing on current practice in 2023 (screening, prevention, and treatment), perceived best practice (barriers and facilitators), and when possible, to compare practice in 2017 and 2023.

METHODS

Self-reported, cross-sectional survey of dysphagia practice in Danish ICUs administered from April to May 2023. In addition, data were compared with the 2017 Dysphagia in Intensive Care Evaluation study, when possible.

RESULTS

Only half of Danish ICUs reported to have a PED protocol, and less than half routinely screen patients for dysphagia after extubation. Most common screening methods were the oral mechanism examination, water test, and Facio-oral tract therapy. Nurses and physicians often relied on an overall physical assessment of the patient. Best treatment methods were uniformly agreed to be patient positioning, modification of food and fluids, use of ergonomic utensils, and compensatory maneuvers. Key barriers to dysphagia management were lack of specialized staff, under-recognition of dysphagia as a health issue, and lack of standardized protocols.

CONCLUSION

Awareness of PED is increasing and identification, prevention, and treatment is slowly improving, but systematic implementation of protocols for dysphagia screening and treatment could enhance dysphagia management in Danish ICUs.

Screening and early detection of post-extubation oropharyngeal dysphagia: a best practice implementation project

INTRODUCTION

Patients undergoing intubation and mechanical ventilation in an intensive care unit risk developing post-extubation oropharyngeal dysphagia (PED). PED can lead to aspiration complications, aspiration pneumonia, and prolonged hospitalization, as well as increased repeat intubation and in-hospital morbidity and mortality.

OBJECTIVE

This evidence implementation project aimed to promote evidence-based screening and early detection of PED in an adult intensive care unit in a secondary public hospital in Brazil.

METHOD

The project followed the seven-phase JBI Evidence Implementation Framework to promote changes at the study site. The JBI Practical Application of Clinical Evidence System (PACES) and Getting Research into Practice (GRiP) approach were also used. The project was developed considering the main barriers to best practices, which were identified through a baseline audit. An educational program was designed to address the identified barriers. Two follow-up audits were then conducted to assess the changes in compliance with the evidence-based practices.

RESULTS

The baseline audit showed deficits in current practices. The first follow-up audit indicated improved compliance with best practices, with five of the seven audit criteria showing 100% compliance. The second follow-up audit indicated that compliance remained at 100% for those five criteria and increased for the other two after an additional intervention to address poor results in nursing care documentation.

CONCLUSION

The first follow-up audit showed good adherence to the educational program for the screening and detection of PED by nurses. The second follow-up audit, in line with the new strategies, showed improvement in nursing documentation.

Dysphagia management by nurses in Spanish intensive care units

INTRODUCTION/PURPOSE

Dysphagia is a disorder that presents with specific signs and symptoms in critically ill patients. Intensive care unit (ICU) nurses are responsible for monitoring and detecting abnormalities in critically ill patients, so they must be trained to assess swallowing and the complications that may arise. The aim of this research is to analyse the dynamics of the detection and assessment of dysphagia by ICU nurses.

METHOD

Cross-sectional descriptive study using an electronic questionnaire to nurses from different Spanish ICUs. The survey was adapted from previous research and consisted of 6 sections with 30 items of qualitative questions. The collection period was between December 2022 and March 2023. Statistical analysis was performed using frequencies and percentages, and the Chi-Square test was used for bivariate analysis.

OUTCOMES

43 nurses were recruited. Dysphagia is considered an important problem (90,7%) but in 50,3% of the units there is no standard or care protocol for this disorder. The most common technique is the swallowing test (32,6%). There is a consensus in our sample that aspiration pneumonia is the main problem; however, nurses in the busiest care units consider sepsis to be a frequent complication (p = ,029). The most common treatment is modification of food consistency (86,0%).

CONCLUSION

The findings of this research show a low systematisation of dysphagia screening in the units included. There is a need for greater implementation of interventions and clinical protocols for monitoring complications as well as for compensatory and rehabilitative management.

Identifying High-Quality Non-Instrumental Dysphagia Screening Tools for Detection of Adult Dysphagia Case in Acute-Care Settings: A Systematic Review

INTRODUCTION

As patients nowadays tend to have multiple diseases and complex medical histories, our aim was to identify high-quality, non-instrumental dysphagia screening tools used for the detection of adult dysphagia cases in all disease categories in acute-care settings.

METHOD

A literature search was conducted in five databases from each database's earliest inception to 31 July 2021 and guided by five keywords: 'dysphagia', 'deglutition', 'screening', 'test' and 'measure'. Without limiting the search in any specific disease category, reviewers assessed original studies and identified tools if they had been validated against instrumental evaluations and if they had been designed as a pass-fail procedure to screen whether dysphagia is absent or present. We further excluded any tool if it was (1) for pediatric focus, or (2) a patient self-report questionnaire. All final tool candidates underwent a methodological quality appraisal using the Revised Tool for the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2).

RESULT

Out of 195 studies with 165 tools identified, 20 tool candidates underwent QUADAS-2 review. We found six high-quality, non-instrumental screening tools for detecting adult dysphagia cases in acute-care settings, including the Yale Swallow Protocol, Gugging Swallowing Screen, Toronto Bedside Swallowing Screening Test (both English and Portuguese versions), Sapienza Global Bedside Evaluation of Swallowing and Two-Step Thickened Water Test. These high-quality tools were developed primarily for patients with stroke. Only Yale Swallow Protocol was originally tested for heterogeneous populations with stroke, multiple sclerosis, traumatic brain injury, oesophageal surgery, neurosurgery and head-and-neck cancer.

CONCLUSIONS

The results highlight the gap in the unavailability of high-quality dysphagia screening tool in several emerged high-risk populations including elderly inpatients, or patients following endotracheal extubation. Further research is needed to determine whether these six tools can be effectively applied across different high-risk populations in acute-care settings to screen for cases finding.

Assessing the oral and suprahyoid muscles in healthy adults using muscle ultrasound to inform the swallowing process: a proof-of-concept study

The oral and suprahyoid muscles are responsible for movements of swallowing. Our study aimed to determine the reproducibility of static and dynamic measurements of these muscles using bedside ultrasound equipment. Forty healthy participants were recruited prospectively. Primary outcomes were evaluation of mass measurements of the anterior bellies of the digastric, mylohyoid, geniohyoid and tongue in B-mode ultrasound. Secondary outcomes were evaluation of geniohyoid muscle layer thickness and function using M-mode. Muscle mass measurements demonstrated little within-participant variability. Coefficient of Variance (CoV) across muscles were: anterior belly digastric (5.0%), mylohyoid (8.7%), geniohyoid (5.0%) and tongue (3.2%). A relationship between sex (r2 = 0.131 p = 0.022) was demonstrated for the geniohyoid muscle, with males having higher transverse Cross Sectional Area (CSA) (14.3 ± 3.6 mm vs. 11.9 ± 2.5 mm, p = 0.002). Tongue size was correlated with weight (r2 = 0.356, p = 0.001), height (r2 = 0.156, p = 0.012) and sex (r2 = 0.196, p = 0.004). Resting thickness of the geniohyoid muscle layer changed with increasing bolus sizes (f = 3.898, p = 0.026). Velocity increased with bolus size (p =  < 0.001, F = 8.974). However swallow time and slope distance did not, potentially influenced by higher coefficients of variation. Oral and suprahyoid muscle mass are easily assessed using bedside ultrasound. Ultrasound may provide new information about muscle mass and function during swallowing.

Independent Risk Factors for Prolonged Tube Feeding After Endotracheal Intubation and Ventilation

PURPOSE

Postextubation dysphagia (PED) can lead to prolonged tube feeding, but risk factors associated with prolonged tube feeding in this population are largely unknown. The purpose of this study was to identify factors independently associated with prolonged tube feeding in adult inpatients who required intubation and mechanical ventilation.

MATERIALS AND METHODS

Retrospective observational cohort study in a dataset of 1.3 million inpatients. Extubated adults without preventilation dysphagia or tube feeding who underwent instrumental swallowing assessment were included. To characterize factors independently associated with prolonged tube feeding, we compiled a set of potential factors, completed factor selection using a random forest algorithm, and performed logistic regression.

RESULTS

In total, 206 of 987 (20.9%) patients had prolonged tube feeding. The regression model produced an area under the curve of 0.79. Factors with the greatest influence on prolonged tube feeding included dysphagia with thickened liquids, dysphagia with soft/solid foods, preadmission weight loss, number of intubations, admission for neurologic disorder, and hospital of admission.

CONCLUSIONS

Several factors predicted prolonged tube feeding after extubation. The strongest were some, but not all, aspects of swallowing function and clinical practice pattern variability. Clinical decision-making should consider bolus-specific data from instrumental swallowing evaluation rather than binary presence or absence of dysphagia.

Dysphagia characteristics at FEES examination in post-extubation patients with COVID-19

Objective

The aims of this study was to analyse fibreoptic endoscopic evaluation of swallowing (FEES) findings in tube-fed patients with coronavirus disease 2019 (COVID-19).

Methods

Seventeen patients who had been intubated during intensive care unit (ICU) stay were enrolled. Pooling of secretions, dysphagia phenotype, penetration/aspiration and residue after swallow were assessed through FEES. The Functional Oral Intake Scale (FOIS) scores were also collected. Patients with significant swallowing impairment were evaluated again after 2 weeks.

Results

All patients were tube-fed at enrollment. According to the FEES results, 7 started total oral feeding with at least one consistency. The more common dysphagia phenotypes were propulsive deficit and delayed pharyngeal phase. Pooling of secretions, penetration/aspiration, and residue after swallow were frequently documented. A significant improvement in FOIS scores was found during the second FEES examination.

Conclusions

Swallowing impairment in patients with severe COVID-19 after discharge from the ICU is characterised by propulsive deficit and delayed pharyngeal phase. Most of these patients required feeding restrictions even if feeding abilities seem to improve over time.

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.

Volume and Practice-Setting Shift of Laryngology Procedures During the COVID-19 Pandemic: A Reg-ENT Database Analysis

Objective

The onset of the coronavirus disease 2019 (COVID-19) pandemic changed practice patterns throughout medicine. The purpose of this study is to evaluate changes in the volume and location setting of laryngology procedures after the onset of COVID-19.

Study Design

Retrospective database cohort study.

Setting

Reg-ENT registry.

Methods

Retrospective review from 2017 to 2022 of patients who underwent a laryngology procedure identified by procedure code categorized by site of service code-"ambulatory surgical" versus "office" setting. Based on March 2020 as the cutoff point, the procedures were designated as pre-COVID versus COVID time period.

Results

A total of 5989 patients underwent laryngology procedures. Forty-two percent more procedures were performed in the COVID period (n = 3780) versus pre-COVID (n = 2209). Pre-COVID, the procedure distribution between office and ambulatory surgical setting was 70% (n = 1546) compared with 30% (663). This shifted to 77% (n = 2920) and 23% (n = 860) during COVID, P = .9. The most common diagnoses associated with laryngology procedures during the study period were vocal fold paralysis 47% (n = 2831), dysphonia 33% (n = 1392), and laryngotracheal stenosis 14% (n = 838). These trends remained in both pre-COVID and COVID time periods. After the start of the pandemic, among patients undergoing laryngology procedures, there was a 93% increase (n = 284-549) in the diagnosis of laryngotracheal stenosis, 70% increase (n = 520-882 patients) in dysphonia and 69% increase (n = 1054-1777) in vocal fold paralysis.

Conclusion

An increase in laryngology procedures performed after the onset of the COVID-19 pandemic was identified with an overall procedural shift to the office-setting.

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.

Incidence and factors associated with dysphagia in intensive care unit patients 24 h after extubation

BACKGROUND

Post-extubation dysphagia deserves attention because it places patients at risk following extubation, especially critically ill patients in intensive care unit. However, there are limited studies of post-extubation dysphagia in the early stages after extubation.

AIMS

To investigate the incidence and factors associated with post-extubation dysphagia among patients in intensive care unit within 24 h of extubation.

STUDY DESIGN

A prospective descriptive study was carried out with 173 adult patients in intensive care unit with tracheal extubation at a tertiary hospital in Guangzhou, China. The Gugging Swallowing Screen was used to evaluate the swallowing function of patients 1, 4 and 24 h after extubation. Demographic and clinical data were retrieved from medical records.

RESULTS

The incidence of post-extubation dysphagia in patients within 1, 4 and 24 h after extubation was 86.71% (n = 150), 63.01% (n = 109) and 43.35% (n = 75), respectively. The risk factors included older age (OR = 1.057, 95%CI [1.039, 1.072], p < .001), cardiovascular disease (OR = 0.098, 95%CI [0.082, 0.127], p = .012), thyroid dysfunction (OR = 5.042, 95%CI [1.527, 13.684], p < .001), non-post-operative admission (OR = 3.186, 95%CI [1.142, 14.422], p = .036), mechanical ventilation duration >48 h (OR = 3.558, 95%CI [1.217, 10.385], p = .020), intubation duration >24 h (OR = 0.533, 95%CI [0.278, 0.898], p = .048) and intubation model size ≤7 (OR = 0.327, 95%CI [0.158, 0.788], p < .01).

CONCLUSIONS

This study revealed a high incidence of post-extubation dysphagia in critical patients in the 24 h after extubation, with the incidence decreasing over time. Screening of early post-extubation dysphagia after extubation is needed, but the specific evaluation time point requires further investigation. Patients with older age, cerebrovascular disease, thyroid dysfunction, post-operative admission, longer mechanical ventilation time, thicker intubation models and longer intubation time have a higher risk of the occurrence of post-extubation dysphagia.

RELEVANCE TO CLINICAL PRACTICE

The incidence of post-extubation dysphagia is very high in the early stage. Within 24 h after extubation, the patient's swallowing function should be actively evaluated, and the occurrence of aspiration should be vigilant. Patients with older age, cerebrovascular disease, thyroid dysfunction, post-operative admission, longer mechanical ventilation time, thicker intubation models and longer intubation time should receive more attention.

It is not just about prescription. A cohort study of the impact of enteral nutrition on mortality of hospitalized patients with COVID-19

Introduction

Introduction: during COVID-19 pandemic, international societies released guidelines and recommendations for patients requiring nutritional support according to previous similar respiratory diseases. Objectives: the aim of the study was to evaluate the nutritional support provided by enteral nutrition (EN) in patients with COVID-19 infection, identify if the recommendations from international societies were met and their impact on mortality rate. Methods: a cohort study was conducted on adult patients with COVID-19 admitted to a tertiary hospital. Demographic, clinical, biochemical, and nutritional variables were obtained. A random-effect parametric survival-time model was performed to quantify the risk of death for each variable, and the Hausman test was used to confirm the model. Results: two hundred and twenty-nine patients were enrolled. The delivered energy was > 80 % of adequacy in the first two days, as suggested by international guidelines (11.7 ± 4.9 kcal/kg); however, an adequacy rate less than 60 % was achieved on day 14 (25.4 ± 7.4 kcal/kg). The protein adequacy was > 75 % on the first days of infusion (1.3 ± 0.3 g/kg); however, the infusion was < 50 % (1.5 ± 0.4 g/kg) after being extubated. Age, sex, and nutritional risk were related to higher mortality in patients with EN, whereas the infused energy and protein, the percentage of protein adequacy, arginine, and n-3 PUFA were associated with lower mortality. Conclusion: achieving at least 80 % of the energy and protein requirements, as well as n-3 PUFA and arginine supplementation could be associated with lower mortality in COVID-19 patients. More studies are needed to confirm the role of these nutrients on the mortality rate.

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.

Development and Validation of a Risk Prediction Model to Predict Postextubation Dysphagia in Elderly Patients After Endotracheal Intubation Under General Anesthesia: A Single-Center Cross-Sectional Study

At present, the incidence and risk factors for dysphagia after extubation in elderly inpatients are still unclear, and we aimed to develop and validate a risk prediction model that prospectively identifies high-risk patients to reduce the occurrence rate of dysphagia. The 469 patients recruited were randomly divided into modeling and validation groups in a 7:3 ratio. In the modeling group, the postextubation dysphagia (PED) risk factors were analyzed, and a risk prediction model was established. In the validation group, the model was validated and evaluated. The model was constructed based on the risk factors determined by a binary logistic regression analysis. The discrimination ability of the model was evaluated by the receiver operating characteristic (ROC) curve. The calibration curve and Hosmer‒Lemeshow test were performed to evaluate the model's calibration ability. The clinical utility of the risk prediction model was analyzed by decision curve analysis (DCA). The results showed that the incidence of PED was 15.99%, and age, duration of indwelling gastric tube, difficult endotracheal intubation, atomization after extubation, anesthesia risk level and frailty assessment were identified as important risk factors. The model was validated to have favorable discrimination, calibration ability and clinical utility. It has a certain extension value and clinical applicability, providing a feasible reference for preventing the occurrence of PED.

Prediction Models for Dysphagia in Intensive Care Unit after Mechanical Ventilation: A Systematic Review and Meta-analysis

OBJECTIVE

Dysphagia is a common condition that can independently lead to death in patients in the intensive care unit (ICU), particularly those who require mechanical ventilation. Despite extensive research on the predictors of dysphagia development, consistency across these studies is lacking. Therefore, this study aimed to identify predictors and summarize existing prediction models for dysphagia in ICU patients undergoing invasive mechanical ventilation.

METHODS

We searched five databases: PubMed, EMBASE, Web of Science, Cochrane Library, and the China National Knowledge Infrastructure. Studies that developed a post-extubation dysphagia risk prediction model in ICU were included. A meta-analysis of individual predictor variables was performed with mixed-effects models. The risk of bias was assessed using the prediction model risk of bias assessment tool (PROBAST).

RESULTS

After screening 1,923 references, we ultimately included nine studies in our analysis. The most commonly identified risk predictors included in the final risk prediction model were the length of indwelling endotracheal tube ≥72 h, Acute Physiology and Chronic Health Evaluation (APACHE) II score ≥15, age ≥65 years, and duration of gastric tube ≥72 h. However, PROBAST analysis revealed a high risk of bias in the performance of these prediction models, mainly because of the lack of external validation, inadequate pre-screening of variables, and improper treatment of continuous and categorical predictors.

CONCLUSIONS

These models are particularly susceptible to bias because of numerous limitations in their development and inadequate external validation. Future research should focus on externally validating the existing model in ICU patients with varying characteristics. Moreover, assessing the acceptance and effectiveness of the model in clinical practice is needed.

Assessing Knowledge, Usage, and Perceptions of the Frazier Free Water Protocol: A Pilot Study

INTRODUCTION

Dysphagia is very common among hospitalized patients and is associated with increased length of hospital stay, morbidity, and mortality. Diet restrictions for dysphagia cause dehydration and discontent. The Frazier Free Water Protocol (FFWP) was developed to improve hydration and quality of life in dysphagia patients by establishing the safety of allowing sips of water between meals. Despite these potential benefits, we hypothesized that the FFWP is not widely utilized. We sought to determine barriers to utilization by assessing the familiarity, usage, and perceptions of the FFWP among health-care providers at our institution.

METHODS

We distributed an anonymous questionnaire to a convenience sample of nurses in the hospital during daily huddles. The questionnaire was adapted from a validated framework to assess provider acceptability of health-care interventions.

RESULTS

Of the 66 surveys distributed, we had 58 completed (88%). Only 10 nurses (17%) had heard of the "FFWP" by name. For those that were familiar with the indications, benefits, and risks of giving free water to patients with dysphagia (n = 18), less than half (39%) reported doing so. No nurses that had less than 10 y of patient care experience gave water to dysphagia patients, even if they knew the indications, benefits, and risks. Similarly, less than a fifth (19%) of all nurses surveyed were comfortable giving water to dysphagia patients, but comfort increased for some if the protocol was recommended by a speech-language pathologist (33%) or physician (13%). Nursing experience of >10 y or in intensive care settings did not yield significant differences in knowledge, usage, or comfort level than those with less years or nonintensive care experience, respectively.

CONCLUSIONS

Nurses are essential to the implementation of the FFWP, yet many are unfamiliar and uncomfortable with utilizing it. Education about the protocol is necessary to improve patient outcomes and quality of life. We plan to provide targeted education about the FFWP as well as assess other members of the health-care team, in an attempt to increase utilization of the protocol and improve dysphagia management.

Development of predictive score for postoperative dysphagia after emergency abdominal surgery in patients of advanced age

Aim

Postoperative dysphagia after emergency abdominal surgery (EAS) in patients of advanced age has become problematic, and appropriate dysphagia management is needed. This study was performed to identify predictive factors of dysphagia after EAS and to explore the usefulness of swallowing screening tools (SSTs).

Methods

This retrospective study included 267 patients of advanced age who underwent EAS from 2012 to 2022. They were assigned to a dysphagia group and non-dysphagia group using the Food Intake Level Scale (FILS) (dysphagia was defined as a FILS level of <7 on postoperative day 10). From 2018, original SSTs including a modified water swallowing test were performed by nurses.

Results

The incidence of postoperative dysphagia was 22.8% (61/267). Patients were significantly older in the dysphagia than non-dysphagia group. The proportions of patients who had poor nutrition, cerebrovascular disorder, Parkinson's disease, dementia, nursing-care service, high intramuscular adipose tissue content (IMAC), and postoperative ventilator management were much higher in the dysphagia than non-dysphagia group. Using logistic regression analysis, high IMAC, postoperative ventilator management, cerebrovascular disorder, and dementia were correlated with postoperative dysphagia and were assigned 10, 4, 3, and 3 points, respectively, according to each odds ratio. The optimal cut-off value was 7 according to a receiver operating characteristics curve. Using 1:1 propensity score matching for high-risk patients, the incidence of postoperative dysphagia was reduced by SSTs.

Conclusions

The new prediction score obtained from this study can identify older patients at high risk for dysphagia after EAS, and SSTs may improve these patients' short-term outcomes.

Persistent Features of Laryngeal Injury Following Endotracheal Intubation: A Systematic Review

This systematic review examined (i) prevalence, severity, and impact of persistent post-extubation laryngeal injury beyond hospital discharge and (ii) differences in persistent laryngeal injury between COVID-19 and non-COVID-19 populations. The review was completed following PRISMA-2020 guidelines. Four databases (PubMed, CINHAL complete, EMBASE, Web of Science) were searched (inception to March 2021). Screening, full text review and data extraction were completed by two reviewers. Primary outcomes were swallow, voice and cough and airway measures obtained after hospital discharge. Quality assessment was measured using Downs & Black Tool and Johanna Briggs Institute Checklist for Cohort Studies. Meta-analysis was not completed due to study heterogeneity. Six cohort studies were included. Total number of participants across the included studies was 436. ICU admission diagnoses included respiratory disease 46% (COVID-19 and non-COVID-19), sepsis 14%, non-sepsis-related organ dysfunction 9%, general medical 11%, general surgical 10%, trauma 2%, ENT 0.6% and other not specified by authors 7%. Outcomes were obtained between 2 and 60 months post hospital discharge. Assessment methods included endoscopic evaluation, clinician ratings and patient-reported outcomes. Persistent features of laryngeal injury identified were airway abnormalities (18.9-27%), dysphonia (13.2-60%) and dysphagia (23-33%). Persistent laryngeal injury was associated with ICU length of stay, respiratory diagnosis and tracheostomy. Study quality ranged from poor-good. This is the first systematic review to examine post-extubation laryngeal injury beyond hospital discharge. Significant gaps in the literature were identified. Given the impact on clinical and patient outcomes, large scale, well-designed research is needed to guide post-ICU service delivery.

Postoperative dysphagia as a predictor of functional decline and prognosis after undergoing cardiovascular surgery

AIMS

Post-extubation dysphagia (PED), an often overlooked problem, is a common and serious complication associated with mortality and major morbidity after cardiovascular surgery. Dysphagia is considered an age-related disease, and evaluating its long-term effects is a pressing issue with rapidly progressing ageing worldwide. Therefore, we examined the effect of PED on functional status and long-term cardiovascular events in patients undergoing cardiovascular surgery.

METHODS AND RESULTS

This single-centre, retrospective cohort study included 712 patients who underwent elective cardiovascular surgery and met the inclusion criteria. Patients were divided into PED and non-PED groups based on their post-operative swallowing status. The swallowing status was assessed using the Food Intake Level Scale. Functional status was evaluated as hospital-associated disability (HAD), defined as a decrease in activities of daily living after hospital discharge compared with preoperative values. The patients were subsequently followed up to detect major adverse cardiac and cerebrovascular events (MACCEs). Post-extubation dysphagia was present in 23% of the 712 patients and was independently associated with HAD (adjusted odds ratio, 2.70). Over a 3.5-year median follow-up period, MACCE occurred in 14.1% of patients. Multivariate Cox proportional hazard analysis revealed HAD to be independently associated with an increased risk of MACCE (adjusted hazard ratio, 1.85), although PED was not significantly associated with MACCE.

CONCLUSION

Post-extubation dysphagia was an independent HAD predictor, with the odds of HAD occurrence being increased by 2.7-fold due to PED. Hospital-associated disability accompanied by PED is a powerful predictor of poor prognosis. Perioperative evaluation and management of the swallowing status, and appropriate therapeutic interventions, are warranted.

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.

Recommendations and Effects of Rehabilitation Programs in Older Adults After Hospitalization for COVID-19: A Scoping Review

ABSTRACT

The aims of this review were to identify studies on physical rehabilitation programs and describe the potential effects on functional outcomes in patients older than 60 yrs at discharge from acute care post-COVID-19. The literature search was conducted in the MEDLINE, Cochrane CENTRAL, EMBASE, PEDro, LILACS, CINAHL, SPORTDiscus, Web of Science, and The Living OVerview of Evidence (L-OVE) COVID-19 databases. Studies with patients older than 60 yrs, hospitalized with COVID-19, and admitted to a rehabilitation program after discharge from acute care were included. Ten studies were included with a total of 572 patients. The prevalence of patients who received post-intensive care rehabilitation was 53% (95% confidence interval, 0.27-0.79; P = 0.001). The rehabilitation program included physiotherapy in nine studies, occupational therapy in three studies, and psychotherapy in two studies. The rehabilitation programs increased aerobic capacity, functional independence in basic activities of daily living, muscle strength, muscle mass, dynamic balance, physical performance, pulmonary function, quality of life, cognitive capacity and mental health. Multidisciplinary rehabilitation programs are necessary for older adults after hospitalization for COVID-19, especially those coming from intensive care units, as rehabilitation has a positive effect on important clinical outcomes.

A bedside swallowing screen for the identification of post-extubation dysphagia on the intensive care unit - validation of the Gugging Swallowing Screen (GUSS)-ICU

PURPOSE

Screening for dysphagia at the intensive care unit (ICU) soon after extubation can prevent aspiration, pneumonia, lower mortality, and shorten re-feeding interval. This study aimed to modify the Gugging Swallowing Screen (GUSS), which was developed for acute stroke patients, and to validate it for extubated patients in the ICU.

METHODS

In this prospective study, forty-five patients who had been intubated for at least 24 h were recruited consecutively at the earliest 24 h after extubation. The modified GUSS-ICU was performed twice by two speech and language therapists independently. Concurrently, gold standard the flexible endoscopic evaluation of swallowing (FEES) was performed by an otorhinolaryngologist. Measurements were conducted within a three-hour period; all testers were blinded to each other's results.

RESULTS

According to FEES, 36 of 45 (80%) participants were diagnosed with dysphagia; 13 of those were severe, 12 moderate, and 11 mild. Compared to FEES, the GUSS-ICU predicted dysphagia well (area under the curve for the initial rater pair: 0.923, 95% CI 0.832-1.000 and 0.923, 95% CI 0.836 -1.000 for the second rater pair). The sensitivity was 91.7% (95% CI 77.5-98.3%) and 94.4% (95% CI 81.3-99.3%); the specificity was 88.9% (51.8-99.7%) and 66.7% (29.9-92.5%); the positive predictive values were 97.1% (83.8-99.5%) and 91.9% (81.7-96.6%), and the negative predictive values were 72.7% (46.8-89%) and 75% (41.9-92.6%) for the first and second rater pairs, respectively. Dysphagia severity classification according to FEES and GUSS-ICU correlated strongly (Spearman's rho: 0.61 for rater 1 and 0.60 for rater 2, p < 0.001). Agreement by all testers was good (Krippendorffs Alpha: 0.73). The interrater reliability showed good agreement (Cohen`s Kappa: 0.84, p < 0.001).

CONCLUSION

The GUSS-ICU is a simple, reliable, and valid multi-consistency bedside swallowing screen to identify post-extubation dysphagia at the ICU.

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.

Is Postextubation Dysphagia Underestimated in the Era of COVID-19? A Systematic Review and Meta-Analysis

OBJECTIVE

To investigate the incidence rate of postextubation dysphagia (PED) in patients with COVID-19, as well as relative factors potentially influencing the clinical course of dysphagia.

DATA SOURCES

Six databases including PubMed, MEDLINE, Embase, ScienceDirect, the Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science were searched with no restriction on the language.

REVIEW METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Data were extracted and cross-examined among 3 of the authors. The random-effects model was adopted for the statistical synthesis. The percentage and 95% confidence interval (CI) were adopted as the effect measurements of the PED incidence rate. Subgroup analyses, sensitivity analyses, and metaregression were also performed to identify the heterogeneity among the studies.

RESULTS

A total of 594 patients were enrolled and analyzed from the 10 eligible studies. The weighted incidence of PED in patients with COVID-19 was 66.5% (95% CI: 49.7%-79.9%). Age was the potential factor influencing the incidence rate after heterogeneity was adjusted by the metaregression analysis.

CONCLUSION

Compared to the current evidence reporting only 41% of the non-COVID patients experienced PED, our study further disclosed that a higher 66.5% of COVID-19 patients suffered from PED, which deserves global physicians' attention. With the association between COVID-19 and dysphagia having been more clearly understood, future clinicians are suggested to identify intubated patients' risk factors earlier to strengthen PED care programs in the era of COVID-19.

The Characteristics and Predicators of Post-extubation Dysphagia in ICU Patients with Endotracheal Intubation

The current status and characteristics of post-extubation dysphagia in intensive care unit (ICU) patients with endotracheal intubation remain unclear, we aimed to evaluate the characteristics and identify the predicators for post-extubation dysphagia, to provide reliable reference to the clinical management and nursing care of dysphagia. Patients who underwent tracheal intubation for mechanical ventilation in the ICU of our hospital from January 1, 2020-May 31, 2021 were selected. The characteristics of patients with and without post-extubation dysphagia were analyzed. Univarinate and binary logistic regression analysis were used to screen the risk factors of dysphagia after extubation, and we established the risk prediction model according to the regression coefficients of each risk factor. 316 ICU patients with endotracheal intubation were included, the incidence of post-extubation dysphagia was 27.85%. Logistic regression analysis showed that age ≥ 65 years (OR 2.368, 95%CI 1.633 ~ 3.946), APACHE II score ≥ 15 (OR 3.727, 95%CI 3.312 ~ 4.202), length of tracheal intubation indwelling ≥ 72 h (OR 2.495, 95%CI 1.824 ~ 3.715), length of gastric tube stay ≥ 72 h (OR 1.923, 95%CI 1.452 ~ 2.882) were the risk factors of post-extubation dysphagia in ICU patients with endotracheal intubation(all p < 0.05). Six score was used as the cuff value of the model with good sensitivity and specificity. The area under the ROC curve and 95% confidence interval was 0.822 (0.746, 0.872). There are many risks of post-extubation dysphagia in ICU patients with endotracheal intubation. For high-risk patients with a score ≥ 6, early nursing care and interventions should be given as soon as possible to reduce the post-extubation dysphagia.

Utility of the modified Volume-Viscosity Swallow Test for bedside screening of dysphagia in critically ill patients

BACKGROUND AND AIM

Aspiration and dysphagia are frequent in critically ill patients, and evidence of the validity of bedside screening tests is lacking. This study evaluated the modified Volume-Viscosity Swallow Test (mV-VST) as a screening tool for aspiration and dysphagia in intensive care unit patients.

METHODS

An observational, prospective longitudinal cohort single-center study included patients older than 18 years old, on mechanical ventilation for at least 48 h, conscious and cooperative. Patients had been admitted in intensive care between March 2016 and August 2019 at a university hospital in Spain. Data from the mV-VST and the flexible endoscopic evaluation of swallowing (FEES) test in extubated and tracheostomized patients were collected; the ROC curve was obtained for each group, and the sensitivity (Se), specificity (Sp), positive (pPV) and negative (nPV) predictive values of mV-VST were calculated and compared with the FEES results. We calculated percentages and 95% confidence intervals (CI) for qualitative variables and means or medians for quantitative variables according to the Shapiro-Wilk test. A univariate analysis identified dysphagia risk factors in each group.

RESULTS

The study included 87 patients: 44 extubated and 43 tracheostomized with similar age, body mass index, Sequential Organ Failure Assessment, Charlson comorbidity index, type and reason for admission. Aspiration with FEES was significantly higher in extubated patients than in tracheostomized patients, 43.2% vs. 23.2%, respectively, p = 0.04. With the mV-VST, aspiration was detected in 54.5% of extubated patients and in 39.5% of tracheostomized patients. In the extubated group, the Se of mV-VST to detect aspiration was 89.5%, Sp was 72%, and nPV was 90%. In the tracheostomized group, Se was 100%, Sp was 78.8%, and nPV was 100%. The ROC curve showed that mV-VST similarly identifies aspiration in extubated and tracheostomized patients.

CONCLUSIONS

Dysphagia and aspiration are frequent amongst patients in intensive care after mechanical ventilation. The mV-VST is a valid screening tool to detect aspiration and dysphagia in extubated and tracheostomized patients.

Instrumentos de rastreio da disfagia pós-intubação prolongada: revisão sistemática da literatura

Introdução: A disfagia pós-extubação afeta uma percentagem significativa de doentes. Contudo o seu rastreio não é realizado de forma sistemática, contribuindo para uma reduzida perceção do problema e predispondo à ocorrência de complicações. Metodologia: Revisão Sistemática da Literatura orientada pelos princípios da Cochrane Screening and Diagnostic Test Methods Group e o Preferred Reporting Items for Systematic Reviews and Meta-Analyses, com o objetivo de identificar os instrumentos de rastreio da disfagia em doentes pós-extubação. Consultadas as bases de dados Medline, Cochrane Library, Scielo, Science Direct e CINAHL e efetuada pesquisa na literatura cinzenta. Como critérios de inclusão foram definidos estudos de validação de instrumentos de rastreio para doentes pós-extubação de intubação prolongada (superior a 48 horas). Resultados: Revistos 7043 artigos dos quais foram selecionados sete para leitura integral, sendo que apenas um cumpria os critérios de inclusão. Discussão: Apenas um instrumento de rastreio de disfagia validado foi identificado para esta população específica. O instrumento apresenta boa fiabilidade entre observadores, no entanto, a sensibilidade, sendo de 81%, significa que parte destes doentes não será identificado como disfágico, o que terá repercussões negativas. Este instrumento foi validado contra avaliação clínica, o que se mostra uma limitação à interpretação dos seus resultados. Conclusão: Não existe versão em português deste instrumento, o que dificulta a elaboração de orientações que sistematizem a abordagem terapêutica para doentes pós-extubação. Advoga-se a sua tradução e validação para o contexto nacional e validação com teste de referência. Protocolo registado na Open Science Framework osf.io/q6k7g a 16 de maio de 2022.

Postextubation dysphagia in critically ill children: A prospective cohort study

INTRODUCTION

Postextubation dysphagia (PED) is reported mainly in adults and is associated with poor outcomes. However, data on pediatric intensive care unit (PICU) patients are scarce. We aimed to assess the incidence, risk factors, and outcomes associated with PED in a PICU population.

METHODS

Between 2019 and 2021, we conducted a prospective, observational cohort study of patients aged 1 month to 15 years. Within 24 h after extubation, a speech-language pathologist routinely screened all consecutive patients receiving mechanical ventilation (>24 h) for dysphagia. A Functional Oral Intake Scale (FOIS) score of less than 6 indicated dysphagia.

RESULTS

A total of 161 patients were included, with a PED incidence of 69%. After adjusting for confounding variables, five variables were significantly associated with PED (odds ratio; 95% confidence interval): age <24 months (4.84; 1.5-15.60), neurological comorbidities (7.47; 1.36-40.96), iatrogenic withdrawal syndrome (5.52; 1.31-23.14), use of neuromuscular blocking agents (4.19; 1.18-14.82), and duration of intubation >72 h (3.22; 1.08-9.64). Dysphagia was significantly associated with longer PICU and hospital stays and a longer delay to oral feeding than patients without PED, 14 versus 7.5 days, 21 versus 15 days, and 6 versus 1 day, respectively. Ten participants (9%) failed to resume total oral intake at hospital discharge.

CONCLUSIONS

These findings indicate that PED is highly prevalent in children and associated with adverse patient outcomes. Identifying a core of risk factors might improve prompt recognition of patients at risk for PED and implement preventive approaches and early interventions.

Prevalence of oropharyngeal dysphagia and risk of mortality among hospitalized COVID-19 patients: A meta-analysis

Background

Post-extubation and neurologic complications in COVID-19 patients have been shown to cause oropharyngeal dysphagia (OD). We performed the first meta-analysis to explore and estimate the pooled prevalence of OD, risk of mortality, and associated factors among hospitalized COVID-19 patients.

Methods

We searched Scopus, PubMed, Embase, CINAHL, WHO COVID-19 database, and Web of Science for literature on dysphagia in COVID-19 patients. We used the generalized linear mixed model (GLMM) to determine the prevalence estimates of OD in the R software and the DerSimonian-Lard random-effects model in the Comprehensive Meta-Analysis software to explore the risk of mortality and associated factors of OD, presented as odds ratios (ORs) and corresponding 95% confidence intervals (CIs). We used Cochran's Q, τ², and the I² statistic to assess heterogeneity and conducted a moderator analysis to identify moderator variables.

Results

We included eighteen studies with a total of 2055 participants from the 910 studies retrieved from electronic databases. The prevalence of OD among hospitalized COVID-19 patients was estimated at 35% (95% CI = 21-52; low certainty of evidence) associated with a high risk of mortality (OR = 6.41; 95% CI = 1.48-27.7; moderate certainty of evidence). Intubation (OR = 16.3; 95% CI = 7.10-37.3; high certainty of evidence), use of tracheostomies (OR = 8.09; 95% CI = 3.05-21.5; high certainty of evidence), and proning (OR = 4.97; 95% CI = 1.34-18.5; high certainty of evidence) among hospitalized COVID-19 patients were highly associated with developing OD. The prevalence of OD was higher among hospitalized COVID-19 patients who were admitted in intensive care units (ICU), intubated, and mechanically ventilated.

Conclusions

The prevalence of OD among hospitalized COVID-19 patients is estimated at 35% associated with a high risk of mortality. OD assessment among hospitalized COVID-19 patients who are managed in an ICU, prone position, intubated, and mechanical ventilated deserves more attention.

The prevalence of post-extubation dysphagia in critically ill adults: an Australian data linkage study

Objective: To define the prevalence of dysphagia after endotracheal intubation in critically ill adult patients. Design: A retrospective observational data linkage cohort study using the Australian and New Zealand Intensive Care Society Adult Patient Database and a mandatory government statewide health care administration database. Setting: Private and public intensive care units (ICUs) within Victoria, Australia. Participants: Adult patients who required endotracheal intubation for the purpose of mechanical ventilation within a Victorian ICU between July 2013 and June 2018. Main outcome measures: Presence of dysphagia, aspiration pneumonia, ICU length of stay, hospital length of stay, and cost per episode of care. Results: Endotracheal intubation in the ICU was required for 71 124 patient episodes across the study period. Dysphagia was coded in 7.3% (n = 5203) of those episodes. Patients with dysphagia required longer ICU (median, 154 [interquartile range (IQR), 78-259] v 53 [IQR, 27-107] hours; P < 0.001) and hospital admissions (median, 20 [IQR, 13-30] v 8 [IQR, 5-15] days; P < 0.001), were more likely to develop aspiration pneumonia (17.2% v 5.6%; odds ratio, 3.0; 95% CI, 2.8-3.2; P < 0.001), and the median health care expenditure increased by 93% per episode of care ($73 586 v $38 108; P < 0.001) compared with patients without dysphagia. Conclusions: Post-extubation dysphagia is associated with adverse patient and health care outcomes. Consideration should be given to strategies that support early identification of patients with dysphagia in the ICU to determine if these adverse outcomes can be reduced.

Airway Ultrasound in Critically Ill Patients: A Narrative Review

Airway assessment and management have a central role in critical care medicine. Airway ultrasound can help us evaluate the anatomy, facilitate interventions such as intubation in difficult airways and tracheostomy, prevent post-extubation complications, and diagnose dysphagia. In this review, we will summarize the current use of ultrasound in airway assessment and management in critically ill patients.

Nutritional Support Protocol for patients with COVID-19

Background & aims

COVID-19 is a hypercatabolic disease with possible pulmonary and gastrointestinal symptoms, and consequent deterioration of the nutritional status and the worst clinical prognosis. This study presents a protocol to guide the nutritional care of adult and elderly people non-critically and critically ill with COVID-19.

Methods

A critical review of the literature was carried out in the databases PubMed, Scielo, Bireme, and Science Direct, in search of articles and guidelines that presented assessment criteria and nutritional conduct for COVID-19 and Severe Acute Respiratory Syndrome (SARS), as well as guidelines for managing the symptoms presented by patients.

Results

The results are recommendations based on the literature and the professional experience of nutritionists who provide nutritional assistance to individuals hospitalized with COVID-19 since the beginning of the pandemic in Brazil. We present tools and suggestions for assessing the nutritional status, calculating nutritional needs, initiating nutritional therapy and monitoring tolerance to it, nutritional monitoring during hospitalization, and guidelines for hospital discharge.

Conclusion

Patients with COVID-19 are at nutritional risk. A complete nutritional assessment (anthropometric, dietary, and laboratory assessment) enables the establishment of an individualized nutritional approach in order to contribute to better clinical and nutritional prognoses.

[Postextubation dysphagia in intensive care patients : Current findings and clinical recommendations]

BACKGROUND

A considerable number of critically ill and mechanically ventilated intensive care patients show pronounced dysphagia after extubation. Many studies have shown that postextubation dysphagia (PED) leads to a significant decline of outcome. The awareness, timely diagnostic procedures and integration of suitable treatment methods in intensive care units are therefore of great importance.

OBJECTIVE

Current basic findings on PED, diagnostic possibilities, therapeutic methods as well as the development of concrete recommendations for clinical practice.

METHODS

A selective literature search was performed in PubMed, Medline and Cochrane using keywords.

RESULTS

In the literature the incidence PED is reported very heterogeneous but is probably at least 10% in intensive care patients after mechanical ventilation. The duration of intubation plays a critical role here. A multifactorial interaction of several factors is assumed to be the cause, whereby the impairment of laryngeal structures is of particular relevance. A PED leads to longer hospital stays, higher mortality, more reintubation and a higher number of patients with tube feeding. With respect to diagnostics, screening by trained nurses, clinical swallowing examinations and, in particular, the use of instrumental examinations by flexible endoscopic evaluation of swallowing (FEES) are recommended. The treatment should include adaptive measures in the sense of an adapted diet but also functional exercises. Innovative approaches, such as electrical stimulation are also conceivable. The aim is primarily to avoid penetration and aspiration in order to counteract respiratory complications.

CONCLUSION

In many intensive care units the clinical picture of PED is still neglected despite clear evidence. A simple algorithm in the treatment of intensive care patients can contribute to early detection and initiation of further steps. These should be integrated into clinical treatment standards.

Impact of Frailty on Postoperative Dysphagia in Patients Undergoing Elective Cardiovascular Surgery

Background

Postextubation dysphagia (PED) is a serious postoperative complication following cardiovascular surgery that can lead to a worse prognosis. On the other hand, frailty is a prognostic factor in patients who undergo cardiac surgery.

Objectives

This study investigated the effect of frailty status on PED and impact of PED on postoperative complications.

Methods

This single-center retrospective cohort study included 644 consecutive patients who underwent elective cardiovascular surgery between May 1, 2014, and December 31, 2020; they were assigned to the PED or non-PED group based on postoperative swallowing status, and postoperative complications were investigated. Frailty status and physical functions, including walking speed, grip strength, Short Physical Performance Battery, and 6-minute walking distance, were preoperatively assessed; the frailty-status cutoff for predicting PED was determined from the receiver-operating characteristic curve.

Results

In this study cohort (mean age 67.7 years), the overall PED prevalence was 14.8%; preoperative frailty had a significantly higher prevalence in the PED group (50.0%) than in the non-PED group (20.3%; P < 0.001). PED correlated with a higher incidence of postoperative pneumonia and prolonged intensive care unit or hospital stay (P < 0.05 for all). After adjustment for confounders, multiple regression analysis revealed that preoperative frailty was independently associated with PED (P < 0.001).

Conclusions

PED occurred commonly after cardiovascular surgery and increased the risk of postoperative complications. Preoperative frailty was independently associated with PED. The 6-minute walking distance was the most powerful predictor of PED. Evaluation of preoperative frailty status is important for risk stratification and prevention of postoperative morbidity in patients undergoing surgery.

Dysphagia Severity and Management in Patients with COVID-19

COVID-19 has resulted in unprecedented numbers of patients treated at intensive care units (ICUs). Dysphagia is a key concern in critical illness survivors. We investigated the severity of dysphagia in COVID-19 and the need to adapt practices to provide efficient care. We reviewed the literature on COVID-19, post-critical-illness dysphagia, and dysphagia and tracheostomy guidelines during the pandemic. Critically ill COVID-19 patients present a high incidence of dysphagia, aggravated by respiratory distress, deconditioning, and neurological complications. Mechanical ventilation (MV), delirium, sedation and weakness are worse in COVID-19 than in other etiologies of critical care. In awake patients, respiratory compromise impairs breathing-swallowing-coughing coordination. Tracheostomy reduces laryngopharyngeal trauma, sedation, delirium, ICU stay and improves swallowing rehabilitation. Tracheostomy weaning and swallowing evaluation is complex in COVID-19 due to respiratory instability and a team discussion will guide adaptations. Patients assessed in the ICU were 67% recommended to be nil by mouth (were aspirating). Two months following hospital discharge, 83% of those who had undergone tracheostomy were managing a normal diet. Severely ill COVID-19 patients are expected to regain swallow function. Dysphagia care is based on adaptation of practices to the patients' multiple impairments.

Risk Score for Predicting Dysphagia in Patients After Neurosurgery: A Prospective Observational Trial

Background: Acquired dysphagia is common in patients with tracheal intubation and neurological disease, leading to increased mortality. This study aimed to ascertain the risk factors and develop a prediction model for acquired dysphagia in patients after neurosurgery.

Methods: A multicenter prospective observational study was performed on 293 patients who underwent neurosurgery. A standardized swallowing assessment was performed bedside within 24 h of extubation, and logistic regression analysis with a best subset selection strategy was performed to select predictors. A nomogram model was then established and verified.

Results: The incidence of acquired dysphagia in our study was 23.2% (68/293). Among the variables, days of neurointensive care unit (NICU) stay [odds ratio (OR), 1.433; 95% confidence interval (CI), 1.141–1.882; P = 0.005], tracheal intubation duration (OR, 1.021; CI, 1.001–1.062; P = 0.175), use of a nasogastric feeding tube (OR, 9.131; CI, 1.364–62.289; P = 0.021), and Acute Physiology and Chronic Health Evaluation (APACHE)-II C score (OR, 1.709; CI, 1.421–2.148; P < 0.001) were selected as risk predictors for dysphagia and included in the nomogram model. The area under the receiver operating characteristic curve was 0.980 (CI, 0.965–0.996) in the training set and 0.971 (0.937–1) in the validation set, with Brier scores of 0.045 and 0.056, respectively.

Conclusion: Patients who stay longer in the NICU, have a longer duration of tracheal intubation, require a nasogastric feeding tube, and have higher APACHE-II C scores after neurosurgery are likely to develop dysphagia. This developed model is a convenient and efficient tool for predicting the development of dysphagia.

Risk Factors for Postextubation Dysphagia: A Systematic Review and Meta-analysis

OBJECTIVES/HYPOTHESIS

To identify, describe, and where possible meaningfully synthesize the reported risk factors for postextubation dysphagia (PED) in critically ill patients.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A systematic search of peer-reviewed and grey literature was conducted in common scientific databases to identify previously evaluated risk factors of PED. Data extraction and risk of bias assessment used a double-blind approach. Random effects models were used for the meta-analyses. Meta-analyses were conducted where sufficient study numbers allowed after accounting for statistical and clinical heterogeneity.

RESULTS

Twenty-five studies were included, which investigated a total of 150 potential risk factors. Of these, 63 risk factors were previously identified by at least one study each as significantly increasing the risk of PED. After accounting for clinical and statistical heterogeneity, only two risk factors were suitable for meta-analysis, gender, and duration of intubation. In separate meta-analyses, neither gender (RR 1.00 [0.71, 1.43], I² = 0%) nor duration of intubation (RR 1.54 [-0.40, 3.49], I² = 0%) were significant predictors of PED.

CONCLUSIONS

A large number of risk factors for PED have been reported in the literature. However, significant variability in swallowing assessment methods, patient populations, timing of assessment, and duration of intubation prevented meaningful meta-analyses for the majority of these risk factors. Where meta-analysis was possible, gender and duration of intubation were not identified as risk factors for PED. We discuss future directions in clinical and research contexts. Laryngoscope, 2020.
