RESUMO
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.
RESUMO
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. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04532398,31/08/2020.

BACKGROUND: Swallowing disorder is a common clinical symptom that can lead to a series of complications, including aspiration, aspiration pneumonia, and malnutrition. This study aimed to investigate risk factors of post-extubation dysphagia (PED) in intensive care unit (ICU) patients with endotracheal intubation, and to develop a risk-predictive model for PED, which could serve as an assessment tool for the prevention and control of PED. METHODS: Patients retrospectively selected from June to December 2021 in a tertiary hospital served as the derivation cohort. Patients recruited from the same hospital from March to June 2022 served as the external validation cohort for the predictive model. We used a combination of variable screening and least absolute shrinkage and selection operator (LASSO) regression to select the most useful candidate predictors and checked the multicollinearity of independent variables using the variance inflation factor method. Multivariate logistic regression analysis was performed to calculate the odds ratio (OR; 95% confidence interval [95% CI]) and P-value for each variable to predict diagnosis. The screened risk factors were introduced into R software to build a nomogram model. The performance of the model, including discrimination ability, calibration, and clinical benefit, was evaluated by plotting the receiver operating characteristic (ROC), calibration, and decision curves. RESULTS: A total of 305 patients were included in this study. Among them, 235 patients (53 PED vs. 182 non-PED) were enrolled in the derivation cohort, while 70 patients (17 PED vs. 53 non-PED) were enrolled in the validation cohort. The independent predictors included age, pause of sedatives, level of consciousness, activities of daily living (ADL) score, nasogastric tube, sore throat, and voice disorder. These predictors were used to establish the predictive nomogram model. The model demonstrated good discriminative ability, and the area under the ROC curve (AUC) was 0.945 (95% CI 0.904-0.970). Applying the predictive model to the validation cohort demonstrated good discrimination with an AUC of 0.907 (95% CI 0.831-0.983) and good calibration. The decision-curve analysis of this nomogram showed a net benefit of the model. CONCLUSION: A predictive model that incorporates age, pause of sedatives, level of consciousness, ADL score, nasogastric tube, sore throat, and voice disorder may have the potential to predict PED in ICU patients.
RESUMO
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.
RESUMO
Introduction: Post-extubation dysphagia (PED) can have serious consequences for critically unwell patients. COVID-19 has resulted in an increasing need for a PED screen in order to effectively identify patients and mitigate risk, whilst balancing under-resourced services. Online training provides the advantage of reducing time pressures on staff and supporting social distancing. This project aimed to adapt the Leeds Post-Extubation Dysphagia Screen (L-PEDS) and the associated training package to be more suitable and effective for use during COVID-19 pandemic. Methods: The screen was modified to a digital format with additional guidance for users. The training package was shortened and converted to an online package while keeping the interactive mode of training. Results: Preliminary results of 14 staff members indicate that the median confidence levels for screening patients for PED improved from 5 to 8 (on a scale of 0 to 10) after completing the L-PEDS-COVID training package. Likewise, knowledge of PED improved from a median of 4 to 8 (on a scale of 0 to 10). Training quality was rated at a median of 8 on a scale of 0 to 10 (0 being very poor; 10 being very good). Conclusions: Preliminary evidence demonstrated increased knowledge of PED and confidence in screening. The development of an adapted version of the L-PEDS and online training package may allow easier implementation of post-extubation dysphagia screening. This could help to compensate for insufficient speech and language therapy critical care staffing, assist in identifying patients at risk and improve outcomes by enabling earlier and safe resumption of oral intake.
RESUMO
Data on long-term effects of post-extubation dysphagia is lacking. We investigate mid- and long-term clinical outcomes in a large sample of ICU patients with systematic dysphagia screening. DESIGN: Outcome analysis with a follow-up of 6 years or death (whichever occurred earlier) of ICU patients from a prospective observational trial (Dysphagia in Mechanically Ventilated ICU Patients study) with systematic dysphagia screening. SETTING: ICU of a tertiary care academic center. PATIENTS: Nine-hundred thirty-three mixed medical-surgical ICU patients (median age, 66 yr; interquartile range [IQR], 54-74, Acute Physiology and Chronic Health Evaluation II score 19 [IQR, 14-24], 71% male). INTERVENTIONS: ICU patients were followed up for a mean follow-up period of 1,731 ± 772 days (4.7 ± 2.1 yr). Primary outcome measures were 180-day and 360-day all-cause mortality in ICU patients with versus without dysphagia. MEASUREMENTS AND MAIN RESULTS: Two-hundred seventy-three patients died (29.3%) during the observational interval (n = 76 lost to follow-up). In dysphagia screening positive versus negative ICU patients, mortality at 180 days was 16% versus 5.8% (excess mortality 10.2%), whereas mortality at 360 days was 25% versus 9.1% (excess mortality 15.9%). Adjustment for confounders in a Cox model revealed a significant association of dysphagia with all-cause mortality in a time-dependent manner. The risk of death in ICU patients with versus without post-extubation dysphagia declined from about 2.5 times higher to about equal risk for both groups over the first year (i.e. 1.03 yr) post-ICU admission (at 360 d: hazard ratio [HR], 1.03; 95% CI, 0.42-3.70). The mean mortality HR for the first year post-ICU admission was HR 2.09 (95% CI, 1.34-3.24; p = 0.0009). CONCLUSIONS: Long-term follow-up of a large cohort of medical-surgical adult ICU patients systematically screened for dysphagia showed that dysphagia is associated with increased hazards for death for up to 1 year after ICU admission. Our data underline effects of post-extubation dysphagia on long-term clinical outcomes in affected critically ill patients.
RESUMO
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.

OBJECTIVE: The main objective was to assess the prevalence of dysphagia in the intensive care unit in patients with coronavirus disease 2019.Methods. A cohort, observational, retrospective study was conducted of patients admitted to the intensive care unit for severe acute respiratory syndrome coronavirus 2 pneumonia at the University Hospital of Rouen in France. RESULTS: Over 4 months, 58 patients were intubated and ventilated, 43 of whom were evaluated. Screening revealed post-extubation dysphagia in 62.7 per cent of patients. In univariate analysis, a significant association was found between the presence of dysphagia and: the severity of the initial pathology, the duration of intubation, the duration of curare use, the degree of muscle weakness and the severity indicated on the initial scan. At the end of intensive care unit treatment, 22 per cent of the dysphagic patients had a normal diet, 56 per cent had an adapted diet and 22 per cent still received exclusive tube feeding. CONCLUSION: Post-extubation dysphagia is frequent and needs to be investigated.

BACKGROUND: A significant portion of critically ill patients with coronavirus disease 2019 (COVID-19) are at high risk of developing intensive care unit (ICU)-acquired swallowing dysfunction (neurogenic dysphagia) as a consequence of requiring prolonged mechanical ventilation. Pharyngeal electrical stimulation (PES) is a simple and safe treatment for neurogenic dysphagia. It has been shown that PES can restore safe swallowing in orally intubated or tracheotomized ICU patients with neurogenic dysphagia following severe stroke. We report the case of a patient with severe neurogenic post-extubation dysphagia (PED) due to prolonged intubation and severe general muscle weakness related to COVID-19, which was successfully treated using PES. CASE PRESENTATION: A 71-year-old Caucasian female patient with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection developed neurogenic dysphagia following prolonged intubation in the ICU. To avoid aerosol-generating procedures, her swallowing function was evaluated non-instrumentally as recommended by recently published international guidelines in response to the COVID-19 pandemic. Her swallowing function was markedly impaired and PES therapy was recommended. PES led to a rapid improvement of the PED, as evaluated by bedside swallowing assessments using the Gugging Swallowing Screen (GUSS) and Dysphagia Severity Rating Scale (DSRS), and diet screening using the Functional Oral Intake Scale (FOIS). The improved swallowing, as reflected by these measures, allowed this patient to transfer from the ICU to a non-intensive medical department 5 days after completing PES treatment. CONCLUSIONS: PES treatment contributed to the restoration of a safe swallowing function in this critically ill patient with COVID-19 and ICU-acquired swallowing dysfunction. Early clinical bedside swallowing assessment and dysphagia intervention in COVID-19 patients is crucial to optimize their full recovery. PES may contribute to a safe and earlier ICU discharge of patients with ICU-acquired swallowing dysfunction. Earlier ICU discharge and reduced rates of re-intubation following PES can help alleviate some of the pressure on ICU bed capacity, which is critical in times of a health emergency such as the ongoing COVID-19 pandemic.

BACKGROUND: Dysphagia related to intubation affects almost one in five patients in the intensive care unit; it may vary due to fluctuations in cerebral status and fatigue and lead to pneumonia, re-intubation and increased mortality. Taking care of patients' nutritional needs is an integral part of nursing and nurses must therefore be able to assess risk of dysphagia at all hours. However, Danish validated methods for use in the critically ill patient population are lacking. AIM: To translate and adapt the Yale Swallow Protocol method for implementation in a Danish intensive care unit setting. METHODS: Translation and adaption followed WHO's recommendations for translation and adaption of instruments. Face validity of the Danish version was evaluated in four group interviews. These were digitally recorded, transcribed and analysed using deductive content analysis. All interviewees gave informed consent. FINDINGS: The translated version of the Yale Swallow Protocol was easy to understand, although nurses needed to have the method explained and needed training in using the method. In addition, the Yale Swallow Protocol must be adapted to local practice in terms of identifying patients at risk of dysphagia and deciding where to document results of the screening. CONCLUSION: The translated version of the Yale Swallow Protocol proved conceptually and culturally sound and acceptable to intensive care unit nurses. Implementation should be followed by theoretical and practical training to build a nursing vocabulary relating to dysphagia and strengthen nurses' sensitivity to clinical manifestations consistent with dysphagia.

BACKGROUND/AIMS: This study aimed to evaluate the correlation between clinical risk factors of post-extubation dysphagia (PED) and the severity of impaired pharyngeal swallowing function assessed via videofluoroscopic swallowing studies (VFSSs). METHODS: This study was a retrospective review of medical records. Of 116 patients who were admitted to the intensive care unit and underwent VFSS, 32 who had non-neurologic disorders and experienced prolonged intubation (for more than 48 hours) were diagnosed with PED. The severity of PED was evaluated by using a functional dysphagia scale (FDS) and a penetration aspiration scale (PAS), on the basis of VFSS. RESULTS: The Simplified Acute Physiology Score 3 and total FDS score were positively correlated (r = 0.40, p = 0.02). Intubation duration was positively correlated with total PAS and FDS scores (r = 0.62, p < 0.001; r = 0.65, p < 0.001, respectively). The amounts of residue in the valleculae (RV) and pyriform sinuses (RP) were associated with intubation duration (r = 0.58, p < 0.001; r = 0.57, p < 0.001, respectively). Multivariate regression analysis revealed that intubation duration was significantly associated with the total FDS score, RV and RP subscales of the FDS, and total PAS score. CONCLUSION: The severity of impaired swallowing function, particularly the amount of residue in the pharyngeal recesses assessed via VFSS, was strongly associated with both severity of medical illness and intubation duration. Intubation duration could be a prognostic factor for assessing impaired swallowing function on the basis of VFSS.

Post-extubation dysphagia is a condition that is becoming a growing concern. The condition occurs in 3-62% of extubated patients and can be related to mixed aetiologies, such as neuromuscular impairment, critical illness and laryngeal damage. The risk factors for developing dysphagia in critically ill patients are under-diagnosed and perhaps underestimated. Recent studies recommend the implementation of a standardized swallowing screen to prevent aspiration and decrease pneumonia rate and mortality. The aim of this quality improvement initiative was the development of a bedside swallowing screening tool to assess effective swallowing post-endotracheal extubation. Post-extubation dysphagia can result in a delay in re-feeding, with the potential for malnutrition as well as overt and covert aspiration if swallowing is not effectively screened. It is apparent that ICU nurses commence the initial screen for swallowing in the absence of an evidence base of care. A review of current local and international practice guidelines excludes the process of an effective swallowing screen of the extubated patient. Previously, a referral to speech and language therapists would be required to assess swallowing only after an initial review by the ICU medical team. This often leads to delays if the referral is made outside normal working practice, such as weekends or evenings. The initial development of a swallowing screening tool is the first step to promoting a nurse-led/-initiated bedside swallow screening tool that will enhance patient care and patient safety. There is growing body of evidence regarding the incidence of post-extubation dysphagia. Currently, there are very few recognized bedside swallowing screening tools to identify patients at risk. The most serious complication associated with post-extubation dysphagia is aspiration pneumonia, which is the leading cause of nosocomial infection in the critically ill patient.
