Abstract
BACKGROUND Almost 260,000 people in Germany suffer from a stroke each year. As a consequence, for more than 60% this leads to dysphagia. In order to prevent secondary diseases, such as pneumonia, malnutrition and dehydration, a differentiated diagnosis by a multiprofessional team in a stroke unit is required. The guidelines in 2015 for diagnosing neurologic dysphagia by the German Society of Neurology recommend a detailed anamnesis, a standardized screening, a clinical swallowing examination and additional instrumental diagnostics. OBJECTIVE This study examined whether dysphagia is diagnosed by speech therapists at certified stroke units according to the recommended guidelines. MATERIAL AND METHODS An online questionnaire was compiled and sent to 1 speech therapist at each of the 195 certified stoke units and 112 participants responded to the questionnaire. The questionnaire consisted of questions about anamnesis, clinical swallowing diagnostics and the instrumental diagnostics. Of the speech therapists working on a stroke unit 57% participated in this study. RESULTS The results show that 50% of the participants elaborated a detailed and differentiated anamnesis, 64% used a standardized screening (Daniels test) and 66% implemented a guideline conform swallowing test. As technical instruments, 35% of the respondents used video fluoroscopy and 71% of the respondents a fiber endoscopy. CONCLUSION The implementation of a detailed and differentiated anamnesis, standardized screening, and a clinical swallowing examination with testing of different food consistencies suggests a high quality of the dysphagia diagnostics at stroke units in Germany. The increasing availability of technical instruments, especially fiber endoscopy, substantiates this view.

Abstract
Early identification of bulbar involvement in persons with ALS is critical for improving diagnosis and prognosis; however, efficacious diagnostic markers have not yet been identified. The purpose of this study was to determine whether kinematic changes of the tongue and jaw during swallowing, measured using 3D electromagnetic articulography (EMA), predate clinically identifiable symptoms of speech and swallowing impairment in persons diagnosed with ALS. Data were collected from 16 adults diagnosed with ALS and 18 neurotypical controls. Groups were aged matched. Eligible participants with ALS were tolerating an unrestricted diet (FOIS = 7), produced intelligible speech (> 97%), and had a speaking rate greater than 150 words per minute. Participants completed a 3-mL water swallow task, during which EMA recorded kinematic measures of the anterior and posterior regions of tongue including lingual speed, range of motion, duration, coordination, and efficiency. Jaw speed and range of motion were also recorded. Persons diagnosed with ALS demonstrated reduced posterior lingual range of motion (11.40 mm ± 4.01 vs. 16.07 mm ± 5.27), slower posterior lingual speeds (83.67 mm/s ± 47.96 vs. 141.35 mm/s ± 66.54), increased lingual movement duration (13.46 s ± 6.75 vs. 9.21 s ± 3.28), and reduced lingual coordination (0.04 s ± 0.11 vs. 17 s ± 0.19) during the 3-oz water swallow task compared to controls. Persons diagnosed with ALS demonstrated increased range of motion (9.86 mm ± 5.38 vs. 6 mm ± 3.78) and increased jaw speed (68.62 mm/s ± 50.13 vs. 34.72 mm/s ± 17.75) during swallowing compared to controls. The current findings suggest that changes in lingual and jaw motor performance during a simple water swallow task are present in persons with ALS who are pre-symptomatic of clinically detectable bulbar impairment.

Abstract
PURPOSE The early detection of dysphagia, a common clinical issue among older adults, is important. However, healthcare professionals sometimes experience difficulties in applying the current screening tools to older adults. Therefore, we developed the Easy Dysphagia Symptom Questionnaire (EDSQ), a simplified tool for the older adults, and investigated its reliability and validity. METHODS The 12-item "yes/no" EDSQ assesses dysphagia symptoms, with a total score being the sum of all "yes" responses. Each item was determined by consensus of three physiatrists after reviewing the previous dysphagia questionnaires. Participants were aged 65 years or older who either complained of or were suspected by a physician of facing swallowing disturbance. They completed the EDSQ, modified water swallow test (MWST), and videofluoroscopic swallowing study. The EDSQ's internal consistency was assessed. Correlations between the EDSQ total score and the MWST, American Speech-Language-Hearing Association's National Outcome Measurement System (ASHA NOMS) swallowing scale, and videofluoroscopic dysphagia scale (VDS) were analyzed. RESULTS The sample comprised 51 participants (29 male, 56.9%; mean age 76.7 ± 6.6 years). Mean EDSQ total score was 4.33 ± 3.03 (range 0-12). Regarding the EDSQ's reliability, the Cronbach's α coefficient was 0.785. The EDSQ total score correlated with the MWST (r = - 0.468, p = 0.001), ASHA NOMS swallowing scale (r = - 0.635, p < 0.001), and VDS (r = 0.449, p = 0.001). The receiver-operating characteristic analysis revealed an optimal cut-off score of ≥ 5, with a sensitivity of 90.9% and a specificity of 67.5%. CONCLUSIONS The EDSQ showed acceptable reliability and validity, indicating its applicability to older adults as a simple screening tool for safe swallowing.

Abstract
Changes in both swallowing and taste commonly occur in advanced age, though the relationship between the two is unknown. This study examined the association between a water swallow screen test and taste identification and intensity rating. Participants included 47 community-dwelling women aged 85–94 years. Participants completed three trials of a water swallow screen and were observed for signs of aspiration, which, if present, indicated failure. Four pure taste stimuli at low and high concentrations and water were presented, and participants selected one of five taste labels and rated their intensity on the generalized Labeled Magnitude Scale. Ratios of intensity ratings were computed for each taste stimulus to compare the perception of low and high concentrations. The association between water swallow screen failure, correct taste identification, and taste intensity ratio was evaluated with logistic regression modeling, with mediating factors of frailty and number of comorbidities. Failure of three water swallow screen trials was associated with a higher taste intensity ratio for caffeine (bitter) and a lower taste intensity ratio for sucrose (sweet). Correct identification of taste, frailty, and number of comorbidities were not associated with failure of any number of water swallow screen trials. Intensity ratings of certain tastes may be associated with swallowing in old-old women. Heightened vigilance in this population may be necessary to prevent complications related to dietary intake.

Abstract
Older adults with multimorbidity, polypharmacy, and complex health needs are the major consumer of health care. Ensuring that medicines are used safely, effectively, and delivered efficiently in this population is challenging. In this context, the approach to medicines delivery should seek to overcome some of the difficulties of delivering medicines to older people, and ensure each medication is delivered by the optimal and most convenient route for the patient in question. However, this poses significant obstacles, as the development of medicines suitable for use in older populations does not often account for complex health needs, potential challenges in relation to drug disposition, safety of excipients and limitations with practical usability of dosage forms. The objective of this review is to summarise and discuss current challenges and novel approaches to delivering medications to older adults.

Abstract
BACKGROUND We initiated a prospective interventional study using a nurse-driven bedside dysphagia screen (BDS) in patients with cervical spine injury (CI) to address three objectives: (1) determine the incidence of dysphagia, (2) determine the utility of the new BDS as a screening tool, and (3) compare patient outcomes, specifically dysphagia-related complications, in the study period with a retrospective cohort. METHODS All patients with CI admitted to a Level I trauma center were enrolled in a prospective 12-month study (June 2016-June 2017) and then were compared with a previous 18-month cohort of similar patients. Our new protocol mandated that every patient underwent a BDS before oral intake. If the patient failed the BDS, a modified barium swallow (MBS) was obtained. Exclusion criteria were emergency department discharge, inability to participate in a BDS, leaving against medical advice, BDS protocol violations, or death before BDS. A failed MBS was defined as a change in diet and a need for a repeat MBS. Dysphagia was defined as a failed MBS or the presence of a dysphagia-related complication. RESULTS Of 221 consecutive prospective patients identified, 114 met inclusion criteria. The incidence of dysphagia was 16.7% in all prospective study patients, 14.9% in patients with isolated CI, and 30.8% in patients with spinal cord injury. The BDS demonstrated 84.2% sensitivity, 95.8% specificity, 80.0% positive predictive value, and 96.8% negative predictive value. There were no dysphagia-related complications. The prospective study patients demonstrated significantly less dysphagia-related complications (p = 0.048) when compared with the retrospective cohort of 276 patients. CONCLUSIONS The introduction of the BDS resulted in increased dysphagia diagnoses, with a significant reduction in dysphagia-related complications. We recommend incorporating BDS into care pathways for patients with CI. LEVEL OF EVIDENCE Study type diagnostic test, level III.

Awareness and Management of Dysphagia in Dutch Intensive Care Units: A Nationwide Survey. Dysphagia 2018; 34:220-228.

Abstract
Dysphagia is a common problem in the intensive care unit (ICU), yet no national guidelines on dysphagia prevention, screening, and management exist. We performed a survey to learn which strategies are commonly being used in Dutch ICUs. A survey was developed based on current literature and experts' opinions. It comprised questions regarding hospital and ICU characteristics, perceived prevalence and importance of dysphagia, screening strategies, modalities used to prevent aspiration, and interventions used to improve swallowing function. It was sent to all 90 non-pediatric ICUs in The Netherlands. 67 of 90 addressed ICUs (74%) replied to our survey. A median relevance score of 4 (IQR 4-5) out of 5 was given to the topic of dysphagia. In 22% and 45% of ICUs, patients were always screened for dysphagia after extubation or tracheotomy, respectively. The water swallow test was always part of the work-up in 88% of ICUs. Fiberoptic endoscopic evaluation of swallowing was used occasionally in 60% of ICUs, versus videofluoroscopic swallowing study in 25%. In 49% of ICUs, no standardized active rehabilitation protocol for dysphagia existed. In the remaining 51%, swallowing exercises were always part of standard rehabilitation, occasionally supplemented by electrical stimulation or surface-EMG biofeedback training in 6 and 10%, respectively. Most Dutch ICUs do not regularly screen for dysphagia and almost half do not seem to have a diagnostic, treatment, or rehabilitation protocol, despite recognizing it as a significant and relatively frequent problem in the ICU with potentially serious patient consequences.

Abstract
Older adults may evidence changes in swallowing physiology. Our goals were to identify dysphagia risk in community-dwelling older adults with no history of dysphagia, and to compare swallowing physiology and safety between older and younger adults. Thirty-two older adults with no history of dysphagia were prospectively recruited and completed the Dysphagia Handicap Index (DHI), two trials of a 3 oz. swallow screen, and videofluoroscopy (VFSS). Self-ratings of swallowing function were compared to published norms by paired t tests, and multivariate logistic regression models were generated to determine whether these ratings and VFSS analysis of swallowing function were associated with failure of one or both swallow screen trials. Archived VFSS of 33 younger adults were compared to older adults with Wilcoxon rank-sum tests. The DHI scores of older adults were higher than published non-dysphagic adults but lower than dysphagic adults. Older participants with greater Oral Residue scores were more likely to fail both swallow screen trials. Older adults received higher median MBSImP™© scores for select pharyngeal components than younger adults. The two age groups did not differ on Penetration-Aspiration Scale scores, and no aspiration was observed. Measures of swallowing in older individuals may reflect age-related sensory and motor changes in the context of functional swallowing and adequate airway protection.

Abstract
BACKGROUND To utilize cervical auscultation as a means of screening for risk of dysphagia, we must first determine how the signal differs between healthy subjects and subjects with swallowing disorders. METHODS In this experiment we gathered swallowing sound and vibration data from 53 (13 with stroke, 40 without) patients referred for imaging evaluation of swallowing function with videofluoroscopy. The analysis was limited to non-aspirating swallows of liquid with either thin (< 5 cps) or viscous ([Formula: see text]) consistency. After calculating a selection of generalized time, frequency, and time frequency features for each swallow, we compared our data against our findings in a previous experiment that investigated identical features for a different group of 56 healthy subjects. RESULTS We found that nearly all of our chosen features for both vibrations and sounds showed significant differences between the healthy and disordered swallows despite the absence of aspiration. We also found only negligible differences between dysphagia as a symptom of stroke and dysphagia as a symptom of another condition. CONCLUSION Non-aspirating swallows from healthy controls and patients with dysphagia have distinct feature patterns. These findings should greatly help the development of the cervical auscultation field and serve as a reference for future investigations into more specialized characterization methods.

Abstract
Cervical auscultation is a method for assessing swallowing performance. However, its ability to serve as a classification tool for a practical clinical assessment method is not fully understood. In this study, we utilized neural network classification methods in the form of Deep Belief networks in order to classify swallows. We specifically utilized swallows that did not result in clinically significant aspiration and classified them on whether they originated from healthy subjects or unhealthy patients. Dual-axis swallowing vibrations from 1946 discrete swallows were recorded from 55 healthy and 53 unhealthy subjects. The Fourier transforms of both signals were used as inputs to the networks of various sizes. We found that single and multi-layer Deep Belief networks perform nearly identically when analyzing only a single vibration signal. However, multi-layered Deep Belief networks demonstrated approximately a 5% to 10% greater accuracy and sensitivity when both signals were analyzed concurrently, indicating that higher-order relationships between these vibrations are important for classification and assessment.

Abstract
Dysphagia is often associated with head and neck and upper gastrointestinal (GI) tract cancers. Evidence suggests that those with solid malignancies in other primary sites may also have swallowing difficulties. Timely and accurate identification of dysphagia is important given the impact it has on hydration, medical treatment, nutrition, prognosis, and quality of life. A systematic review was conducted to identify swallow screening, evaluation, and quality of life tools for those with solid malignancies outside the head and neck and upper GI tract. Ten electronic databases, one journal and two published conference proceedings were searched. Following deduplication, 7435 studies were examined for relevance. No tools were validated solely in this cancer population, though some included this group in larger cohorts. Comments are provided on the diagnostic properties and applicability of these tools. In the absence of appropriate diagnostic instruments, the exact prevalence of dysphagia and its impact on clinical and psychosocial well-being remain unknown. Accurate and adequate measurement of therapeutic intervention is also compromised. This review establishes the need for validated dysphagia evaluation tools for this clinical population.

Abstract
BACKGROUND AND AIMS Our aim is to review the literature and provide guidelines for the assessment of uninvestigated dysphagia. METHODS A systematic literature search identified studies on dysphagia. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach. Statements were discussed and revised via small group meetings, teleconferences, and a web-based platform until consensus was reached by the full group. RESULTS The consensus includes 13 statements focused on the role of strategies for the assessment of esophageal dysphagia. In patients presenting with dysphagia, oropharyngeal dysphagia should be identified promptly because of the risk of aspiration. For patients with esophageal dysphagia, history can be used to help differentiate structural from motility disorders and to elicit alarm features. An empiric trial of proton pump inhibitor therapy should be limited to four weeks in patients with esophageal dysphagia who have reflux symptoms and no additional alarm features. For patients with persistent dysphagia, endoscopy, including esophageal biopsy, was recommended over barium esophagram for the assessment of structural and mucosal esophageal disease. Barium esophagram may be useful when the availability of endoscopy is limited. Esophageal manometry was recommended for diagnosis of esophageal motility disorders, and high-resolution was recommended over conventional manometry. CONCLUSIONS Once oropharyngeal dysphagia is ruled out, patients with symptoms of esophageal dysphagia should be assessed by history and physical examination, followed by endoscopy to identify structural and inflammatory lesions. If these are ruled out, then manometry is recommended for the diagnosis of esophageal dysmotility.

Abstract
BACKGROUND Early detection of dysphagia is critical to reducing hospital complications and length of stay in patients with various types of strokes. The aim of this study was to develop and evaluate the DePaul Hospital Swallow Screener (DHSS) tool to assess for dysphagia in patients with stroke. METHODS This prospective observational study investigated patients admitted to a comprehensive stroke center. The DHSS is composed of a questionnaire containing 8 nonswallow items and a water swallow test. All patients admitted under a standard stroke protocol are screened by the nursing staff using the DHSS and then objectively evaluated by a speech-language pathologist using the Mann Assessment of Swallowing Ability (MASA). Validity measures and reliability through Cohen's κ-coefficient with associated 95% confidence intervals were calculated. RESULTS A total of 224 patients completed the DHSS and had at least 1 MASA score. The overall Content Validity Index score for the DHSS was .92. Compared with the MASA dysphagia cutoff value, the DHSS had a specificity of 93% and a sensitivity of 69%, and compared with the MASA aspiration risk cutoff value, the DHSS had a specificity of 90% and a sensitivity of 70%. Stratified analysis for those with any documented stroke (ischemic or hemorrhagic) compared with those admitted with transient ischemic attack or no stroke yielded similar sensitivity and specificity in both dysphagia and aspiration risk. CONCLUSION The DHSS is a valid and reliable swallow screening tool with moderate agreement, high specificity, and reliable predictive values when compared with the MASA.

Neural Mechanisms of Swallowing Dysfunction and Apraxia of Speech in Acute Stroke. Dysphagia 2018; 33:610-615.

Abstract
Speech and swallowing utilize overlapping anatomy and are thus inherently related processes. We sought to identify common neural mechanisms between risk of swallowing dysfunction and apraxia of speech (AOS). This was a retrospective analysis using data from a prospectively collected cohort. Left hemisphere stroke patients (68 subjects) tested with the Apraxia Battery for Adults II, a swallow screen, and MRI were included in the study. Main outcome measure was the presence of AOS or aspiration risk after stroke. We identified a significant association between AOS measures and increased aspiration risk (defined by failed swallow screen; p = 0.04; OR 5.2). Lesions in pars opercularis of Broca's area (BA 44) were associated with both AOS (p = 0.044; OR 9.7) and increased aspiration risk (p = 0.04; OR 5) but deficits rarely co-occurred in the same cases. Lesions in left premotor cortex (BA 6) were not significantly associated with increased aspiration risk (p = 0.06; OR 3.3) but were significantly associated with AOS (p = 0.008; OR 7). Impaired swallowing function was also associated with lesions in Wernicke's area (BA 22; p = 0.05; OR 3.5) and pars triangularis (BA 45; p = 0.02; OR 6.8). AOS and risk of aspiration are associated in patients with acute left hemisphere stroke. Acute infarct in the pars opercularis of Broca's area is associated with both deficits, though they rarely co-occur in the same individual. The co-occurrence of AOS and risk of aspiration likely reflects dependence on closely related neural structures.

Abstract
OBJECTIVES To compare the videofluoroscopic findings of patients with suspected oropharyngeal dysphagia with the results of a clinical screening protocol. METHODS A retrospective observational cohort study was conducted on all consecutive patients with suspected oropharyngeal dysphagia between March 2015 and February 2016 who were assigned to receive a videofluoroscopic assessment of swallowing. All patients were first submitted to videofluoroscopy and then to the clinical assessment of swallowing. The clinical assessment was performed within the first 24 hours after videofluoroscopy. The videofluoroscopy results were analyzed regarding penetration/aspiration using an 8-point multidimensional perceptual scale. The accuracy of the clinical protocol was analyzed using the sensitivity, specificity, likelihood ratios and predictive values. RESULTS The selected sample consisted of 50 patients. The clinical protocol presented a sensitivity of 50% and specificity of 95%, with an accuracy of 88%. "Cough" and "wet-hoarse" vocal quality after/during swallowing were clinical indicators that appeared to correctly identify the presence of penetration/aspiration risk. CONCLUSION The clinical protocol used in the present study is a simple, rapid and reliable clinical assessment. Despite the absence of a completely satisfactory result, especially in terms of the sensitivity and positive predictive values, we suggest that lower rates of pneumonia can be achieved using a formal dysphagia screening method.

Abstract
Traditional dysphagia prescreening diagnostic methods require doctors specialists to give patients a total score based on a water swallow test scale. This method is limited by the high dimensionality of the diagnostic elements in the water swallow test scale with heavy workload (Towards each patient, the scale requires the doctors give score for 18 diagnostic elements respectively) as well as the difficulties of extracting and using the diagnostic scale data's non-linear features and hidden expertise information (Even with the scale scores, specific diagnostic conclusions are still given by expert doctors under the expertise). In this paper, a hybrid classifier model based on Nonlinear-Principal Component Analysis (NPCA) and Deep Belief Networks (DBN) is proposed in order to effectively extract the diagnostic scale data's nonlinear features and hidden information and to provide the key scale elements' locating methods towards the diagnostic results (The key scale elements that affect different diagnostic conclusions are given to improve the efficiency and pertinence of diagnosis and reduce the workload of diagnosis). We demonstrate the effectiveness of the proposed method using the frame of 'information entropy theory'. Real dysphagia diagnosis examples from the China-Japanese Friendship Hospital are used to demonstrate applications of the proposed methods. The examples show satisfactory results compared to the traditional classifier.

Abstract
Background and purpose Preliminary evidence has shown that reduced ability to maximally raise vocal pitch correlates with the occurrence of aspiration (i.e., airway invasion by food or liquid). However, it is unclear if this simple task can be used as a reliable predictor of aspiration in stroke patients. Our aim was to examine whether maximum vocal pitch elevation predicted airway invasion and dysphagia in stroke. Methods Forty-five consecutive stroke patients (<1 month poststroke) at a rehabilitation setting participated in a videofluoroscopic swallow study and two maximum vocal pitch elevation tasks. Maximum pitch was evaluated acoustically [maximum fundamental frequency (max F0)] and perceptually. Swallowing safety was rated using the Penetration/Aspiration Scale and swallowing performance was assessed using components of the Modified Barium Swallow Impairment Profile (MBSImPTM©). Data were analyzed using simple regression and receiver operating characteristics curves to test the sensitivity and specificity of max F0 in predicting aspiration. Correlations between max F0 and MBSImP variables were also examined. Results Max F0 predicted silent aspiration of small liquid volumes with 80% sensitivity and 65% specificity (p = 0.023; area under the curve: 0.815; cutoff value of 359.03 Hz). Max F0 did not predict non-silent aspiration or penetration in this sample and did not significantly correlate with MBSImP variables. Furthermore, all participants who aspirated silently on small liquid volumes (11% of sample) had suffered cortical or subcortical lesions. Conclusion In stroke patients (<1 month poststroke), reduced maximum pitch elevation predicts silent aspiration of small liquid volumes with high sensitivity and moderate specificity. Future large-scale studies focusing on further validating this finding and exploring the value of this simple and non-invasive tool as part of a dysphagia screening are warranted.

Abstract
OBJECTIVE Tracheostomy tubes (TT) are often needed in patients with severe neurologic injuries to protect the respiratory system from aspiration. However, TTs alter physiological oral-nasal airflow and are suspected to influence the pattern of pharyngeal swallowing. The aim of this work was to evaluate the effect of TT occlusion on pharyngeal swallowing physiology and to determine penetration-aspiration (PA) values of open versus closed TTs in neurogenic dysphagia. DESIGN Prospective controlled clinical study with 20 tracheotomized patients after unilateral hemispheric stroke. Pharyngeal manometry and flexible endoscopic evaluation of swallowing were performed simultaneously to determine pharyngoesophageal pressure and timing, as well as PA scores with open and occluded TTs. In each condition, patients had to swallow 5 mL of puree 5 times. RESULTS Pharyngoesophageal pressure amplitudes, duration, and timing of the swallows did not change as a result of the tracheostomy tube status. Penetration-aspiration values were significantly lower in the occluded tube condition (P = 0.024). CONCLUSIONS Airflow and tracheostomy tube status did not influence the physiology of pharyngoesophageal swallowing in patients with neurogenic dysphagia. However, occluded TTs permitted the voluntary clearance of laryngeal residue and resulted in improved PA scores. We recommend performing dysphagia therapy in tracheotomized patients as soon as possible with uncuffed and occluded tubes.

Abstract
PURPOSE Treatment in intensive care units (ICUs) often results in swallowing dysfunction. Recent longitudinal studies have described the recovery of critically ill people, but we are not aware of studies of the recovery of swallowing function in patients with ICU-acquired muscle weakness. This paper aims to describe the time course of regaining water swallowing function in patients with ICU-acquired weakness in the post-acute phase and to describe the risks of regaining water swallowing function and the risk factors involved. METHODS This cohort study included patients with ICU-acquired muscle weakness in our post-acute department, who were unable to swallow. We monitored the process of regaining water swallowing function using the 3-ounce water swallowing test. RESULTS We included 108 patients with ICU-acquired muscle weakness. Water swallowing function was regained after a median of 12 days (interquartile range =17) from inclusion in the study and after a median of 59 days (interquartile range= 36) from the onset of the primary illness. Our multivariate Cox Proportional Hazard model yielded two main risk factors for regaining water swallowing function: the number of medical tubes such as catheters at admission to the post-acute department (adjusted hazard ratio [HR] = 1.282; 95% confidence interval [CI]: 1.099-1.495) and the time until weaning from the respirator in days (adjusted HR =1.02 per day; 95%CI: 0.998 to 1.008). CONCLUSION We describe a time course for regaining water swallowing function based on daily tests in the post-acute phase of critically ill patients. Risk factors associated with regaining water swallowing function in rehabilitation are the number of medical tubes and the duration of weaning from the respirator. Implications for rehabilitation Little guidance is available for the management of swallowing dysfunction in the rehabilitation of critically ill patients with intensive-care-units acquired muscle weakness. There is a time dependent pattern of recovery from swallowing dysfunction with daily water swallowing tests in the post-acute phase of critically ill patients. Daily water swallowing tests can be used to test swallowing dysfunction in the post-acute phase of critically ill patients The amount of medical tubes and the duration of weaning from respirator are associated risk factors for recovery of swallowing dysfunction.

Abstract
BACKGROUND Dysphagia with subsequent aspiration occurs in up to 60% of acute respiratory failure (ARF) survivors. Accurate bedside tests for aspiration can reduce aspiration-related complications while minimizing delay of oral nutrition. In a cohort of ARF survivors, we determined the accuracy of the bedside swallowing evaluation (BSE) and its components for detecting aspiration. METHODS Patients who were extubated after at least 24hours of mechanical ventilation were eligible for enrollment. Within 3 days of extubation, patients underwent comprehensive BSE including 3-oz water swallowing test (3-WST), followed by a criterion standard test for aspiration, flexible endoscopic evaluation of swallowing (FEES). RESULTS Forty-five patients were included in the analysis. Median patient age was 55years (interquartile range, 47-65). Median duration of mechanical ventilation was 3.3days (interquartile range 1.8-6.0). Fourteen patients (31%) aspirated on FEES. Physical examination findings on BSE and abnormal swallowing during trials of different consistencies were variably associated with aspiration. Compared with FEES, the 3-WST yielded a sensitivity of 77% (95% confidence interval [CI], 50%-92%), specificity of 65% (95% CI, 47%-79%), and an area under the receiver operating characteristic curve (AUC) of 0.71; a speech language pathologist's recommendation for altered diet yielded a sensitivity of 86% (95% CI, 60%-96%), a specificity of 52% (95% CI, 35%-68%), and an AUCof 0.69; an speech language pathologist's recommendation for nil per os (nothing by mouth) yielded a sensitivity of 50% (95% CI, 27%-73%), a specificity of 94% (95% CI, 79%-98%), and an AUCof 0.72. CONCLUSIONS The BSE and its components, including the 3-WST, demonstrated variable accuracy for aspiration in survivors of ARF. Investigation to determine the optimal noninvasive test for aspiration in ARF survivors is warranted.

Abstract
Background Swallowing difficulties are common, and dysphagia occurs frequently in intensive care unit (ICU) patients after extubation. Yet, no guidelines on postextubation swallowing assessment exist. We aimed to investigate the safety and effectiveness of nurse-performed screening (NPS) for postextubation dysphagia in the medical ICU. Methods We conducted a retrospective cohort study of mechanically ventilated patients who were extubated in a 20-bed medical ICU. Phase I (no NPS, October 2012 to January 2014) and phase II (NPS, February 2014 to July 2015) were compared. In phase II, extubated patients received NPS up to three times on consecutive days; patients who failed were referred to speech-language pathologists. Outcomes analyzed included oral feeding at ICU discharge, reintubation, ICU readmission, postextubation pneumonia, ICU and/or hospital mortality, and ICU and/or hospital length of stay (LOS). Subgroup analysis was done for patients extubated after >72 h of mechanical ventilation, as the latter may predispose patients to postextubation dysphagia. Multivariable adjustments for Acute Physiology and Chronic Health Evaluation (APACHE) II score and comorbidities were done because of baseline differences between the phases. Results A total of 468 patients were studied (281 in phase I, 187 in phase II). Patients in phase II had higher APACHE II scores than those in phase I (27.2 ± 8.2 vs. 25.4 ± 8.2; P = 0.018). Despite this, patients in phase II showed a 111 % increase in (the odds of) oral feeding at ICU discharge and a 59 % decrease in postextubation pneumonia (multivariate P values 0.001 and 0.006, respectively). In the subgroup analysis, NPS was associated with a 127 % increase in oral feeding at ICU discharge, an 80 % decrease in postextubation pneumonia, and a 25 % decrease in hospital LOS (multivariate P values 0.021, 0.004, and 0.009, respectively). No other outcome differences were found. Conclusions NPS for dysphagia is safe and may be superior to no screening with respect to several patient-centered outcomes.

Abstract
PURPOSE The clinical swallowing evaluation (CSE) represents a critical component of a comprehensive assessment of deglutition. Although universally utilized across clinical settings, the CSE demonstrates limitations in its ability to accurately identify all individuals with dysphagia. There exists a need to improve assessment and screening techniques to improve health outcomes, treatment recommendations and ultimately mortality in individuals at risk for dysphagia. The following narrative review provides a summary of currently used validated CSE's and examines the potential role of cough testing and screening in the CSE. RECENT FINDINGS Recent evidence highlights a relationship between objective physiologic measurements of both voluntarily and reflexively induced cough and swallowing safety status across several patient populations. Although more research is needed across a wider range of patient populations to validate these findings; emerging data supports the consideration of inclusion of cough testing during the CSE as an index of airway defense mechanisms and capabilities in individuals at risk for aspiration. SUMMARY The sensorimotor processes of cough and swallowing share common neuroanatomical and functional substrates. Inclusion of voluntarily or reflexively induced cough testing in the CSE may aide in the identification of dysphagia and reduced airway protection capabilities.

Abstract
Communication and swallowing disorders are common after stroke. Targeted surveillance followed by prompt evaluation and treatment is of paramount importance. The overall goals of rehabilitation for impaired swallowing and communication and swallowing deficits may differ based on the specific deficits caused by the stroke but the main goal is always to improve the patient's everyday interpersonal interactions and optimize participation in society. Fortunately, therapeutic or compensatory interventions can decrease the effects that communication and swallowing deficits have on the quality of life of stroke survivors.

Abstract
United States census data project dramatic increases in the geriatric population ageing demographics by 2060 with concomitant health-care consequences. The purpose of this replication and continuation study was to collect new 2014 demographic data relative to ageing, swallow evaluation referral rates, and oral feeding status in geriatric-hospitalized patients for comparison with published data from 2000 to 2007. This was a planned data acquisition study of consecutive hospitalized patients referred for swallow assessments. Swallow evaluation referral rates for 2014 were described according to inpatient discharges, age range 60-105 years grouped by decade, gender, admitting diagnostic category, results of swallow evaluations, and oral feeding status. Determination of aspiration risk status was made with the Yale Swallow Protocol and diagnosis of dysphagia made with fiberoptic endoscopic evaluation of swallowing (FEES). There were 1348 referrals and 961 patients ≥60 years of age participated. Overall swallow evaluation referral rates increased an average of 63 % between the comparison years 2007 and 2014 with consistent increases corresponding to the decades, i.e., 60-69 (46 %), 70-79 (68 %), 80-89 (53 %), and 90+ (222 %). A total of 75 % of participants resumed oral alimentation and oral medications. Swallow evaluation referral rates increased by 63 % for 60-90+ year-old acute care geriatric-hospitalized participants despite only a 23 % increase in inpatient discharges for the years 2007 versus 2014. This corroborated previously reported increases for individual years from 2000 to 2007. For timely, safe, and successful initiation of oral alimentation, it is important to perform a reliable swallow screen for aspiration risk assessment with the Yale Swallow Protocol and, if failed, instrumental testing with FEES. More dysphagia specialists are needed through 2060 and beyond due to projections of continued population ageing resulting in ever increasing referral rates for swallow assessments.

Abstract
OBJECTIVE To investigate electrophysiological parameters of swallowing in all stages of Alzheimer's disease. METHODS Forty Alzheimer's disease patients, 20 age-matched normal controls and 20 young normal controls were included. Dysphagia limit (DL) and sequential water swallowing (SWS) tests were performed. Cardiac rhythm, respiration and sympathetic skin responses were concomitantly recorded. RESULTS Dysphagia was found in 30/40 (75%) of Alzheimer's disease patients. Mean volume at the DL test was significantly reduced (16.5±1.0mL) in the Alzheimer's disease group. Swallowing and apnea times in the SWS test were significantly prolonged in elderly controls, but even longer in Alzheimer's disease patients. CONCLUSIONS Alzheimer's disease patients had electrophysiological features of dysphagia, even in the early period of disease. The cortical involvement and severity of cognitive disorder can increase swallowing problems, but subclinical signs of dysphagia may be observed even in patients with mild or moderate Alzheimer's disease.

Abstract
OBJECTIVE To develop and validate a nurse-administered screening tool to identify aspiration risk in patients with suspected stroke. DESIGN Validity study comparing evidence-based swallowing screening items with the videofluoroscopic swallowing study (VFSS) results. SETTING A certified primary stroke center in a major metropolitan medical facility. PARTICIPANTS Consecutive patients (N=250) admitted with suspected stroke. INTERVENTIONS Patients were administered evidence-based swallowing screening items by nurses. A VFSS was completed within 2 hours of swallowing screening. MAIN OUTCOME MEASURES Validity relative to identifying VFSS-determined aspiration for each screening item and for various combinations of items. RESULTS Aspiration was identified in 29 of 250 participants (12%). Logistic regression revealed that age (P=.012), dysarthria (P=.001), abnormal volitional cough (P=.030), and signs related to the water swallow trial (P=.021) were significantly associated with aspiration. Validity was then determined on the basis of the best combination of significant items for predicting aspiration. The results revealed that age >70 years, dysarthria, or signs related to the water swallow trial (ie, cough, throat clear, wet vocal quality, and inability to continuously drink 90mL water) yielded 93% sensitivity and 98% negative predictive value. CONCLUSIONS The final validated tool, Rapid Aspiration Screening for Suspected Stroke, is a valid nurse-administered tool to detect risk of aspiration in patients presenting with suspected stroke.

Screening Accuracy for Aspiration Using Bedside Water Swallow Tests: A Systematic Review and Meta-Analysis. Chest 2016; 150:148-63.

Abstract
BACKGROUND Hospitalizations for aspiration pneumonia have doubled among older adults. Using a bedside water swallow test (WST) to screen for swallowing-related aspiration can be efficient and cost-effective for preventing additional comorbidities and mortality. We evaluated screening accuracy of bedside WSTs used to identify patients at risk for dysphagia-associated aspiration. METHODS Sixteen online databases, Google Scholar, and known content experts through May 2015 were searched. Only prospective studies with patients ≥ 18 years of age given WST screenings validated against nasoendoscopy or videofluoroscopy were included. Data extraction used dual masked extraction and quality assessment following Meta-analysis of Observational Studies in Epidemiology guidelines. RESULTS Airway response (eg, coughing/choking) with or without voice changes (eg, wet/gurgly voice quality) was used to identify aspiration during three different bedside WSTs. Pooled estimates for single sip volumes (1-5 mL) were 71% sensitive (95% CI, 63%-78%) and 90% specific (95% CI, 86%-93%). Consecutive sips of 90 to 100 mL trials were 91% sensitive (95% CI, 89%-93%) and 53% specific (95% CI, 51%-55%). Trials of progressively increasing volumes of water were 86% sensitive (95% CI, 76%-93%) and 65% specific (95% CI, 57%-73%). Airway response with voice change improved overall accuracy in identifying aspiration. CONCLUSIONS Currently used bedside WSTs offer sufficient, although not ideal, utility in screening for aspiration. Consecutive sips with large volumes in patients who did not present with overt airway responses or voice changes appropriately ruled out risk of aspiration. Small volumes with single sips appropriately ruled in aspiration when clinical signs were present. Combining these bedside approaches may offer improved screening accuracy, but further research is warranted.

Abstract
BACKGROUND Acute cerebral stroke is a common problem that is frequently associated with dysphagia resulting in an increased risk of aspiration pneumonia, complication, and mortality. METHODS A literature review was carried out using the search terms 'stroke unit and endoscopy', 'stroke unit and dysphagia', and 'stroke unit and gastroenterology'. RESULTS Only few papers focus on the role of endoscopy in stroke units. One major role is the early detection of dysphagia by flexible endoscopic evaluation of swallowing (FEES). FEES appears to have a higher sensitivity and specificity compared to bedside tests and challenges videofluoroscopy. In contrast, other stroke-associated gastrointestinal complications requiring endoscopic diagnostic or therapeutic intervention, such as gastrointestinal bleeding, abdominal pain, or stasis, and the need to provide fluid and food via gastrostomy or jejunostomy are rarely seen in stroke units and become relevant during and after the rehabilitation phase. CONCLUSION FEES should involve an interdisciplinary team comprising neurologists, speech and language pathologists and/or therapists, as well as gastroenterologic endoscopists.

Abstract
BACKGROUND There is a need for improved clinical identification of hospitalized patients at risk of aspiration. We evaluated our novel phonetic test in a broad spectrum of patients at risk of aspiration in the ICU or intermediate care unit. METHODS We prospectively enrolled 60 hospitalized patients with aspiration risk, between December 2009 and September 2011, who subsequently underwent audio-recorded three-component phonetic bedside evaluation. The recordings were scored by two blinded speech-language pathologists. The institutional dysphagia admission screening test was performed by a bedside nurse. The primary outcomes, dysphagia and aspiration, were assessed by a videofluoroscopic swallowing study, fiber-optic endoscopic evaluation of swallowing, or both. We assessed the short- and long-term clinical outcomes (length of stay, subsequent aspiration pneumonia and respiratory failure, survival) and how these were associated with the phonetic and swallow assessments. RESULTS Statistically significant linear associations with dysphagia were noted for all three individual phonetic components. Also, there were statistically significant linear associations with aspiration for diadochokinesis (P = .050) and consensus auditory-perceptual evaluation of voice (P = .025). Diadochokinesis alone predicted dysphagia (area under the curve [AUC], 0.74; P = .001) and aspiration (AUC, 0.67; P = .012). Its predictive ability improved when combined with normalized dysphagia admission screening test results (AUC, 0.79; P = .001). The short- and long-term clinical outcomes were adversely affected by the worse phonetic/swallowing scores, although they were not statistically different. CONCLUSIONS Abnormal phonation among ICU and intermediate care unit patients is associated with dysphagia and aspiration. Future investigative efforts should uncover the most effective combination of evaluations for accurate bedside detection of dysphagia and aspiration risk in a broad spectrum of patients.

Abstract
Swallowing disorders are frequent. The main concern is mortality due to aspiration-induced pneumonia and malnutrition. In addition, quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract, and sequelae of tumor treatment in the head and neck region are the main pathologic entities. Predominantly ENT physicians and phoniatricians are asked for diagnostics and therapy, and will coordinate the interdisciplinary treatment according to the endoscopic findings. A differentiated approach in history, diagnostics, and symptom-oriented treatment is necessary for these mostly complex disorders. Integration of non-medical staff such as speech therapists, physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over in close cooperation. In particular, an interdisciplinary cooperation with the staff of intensive care medicine is essential. The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists. Endoscopy is a medical service that is basically not delegable. Consequently, substitution of the physician is excluded.

Abstract
AIM The purpose of this study was to develop a revised version of the Brief Bedside Dysphagia Screening Test for determining penetration/aspiration risk in patients prone to dysphagia. The priority was to achieve high sensitivity and negative predictive value. METHODS The study screeners conducted bedside assessment of the swallowing function in 157 patients with a neurological (mainly stroke) or an ear, nose, and throat diagnosis (mainly head and neck cancer). The results were compared with a gold standard, flexible endoscopic examination of swallowing. RESULTS For the neurological subgroup (N = 106), eight statistically significant bedside assessment items were combined into the Brief Bedside Dysphagia Screening Test-Revised (BBDST-R). Cut-off score 1 produced the highest sensitivity (95.5%; 95% confidence interval CI [CI]: 84.9-98.7%) and negative predictive value (88.9%; 95% CI 67.2-96.9%). CONCLUSION The BBDST-R is suitable for dysphagia screening in departments caring for patients with neurological conditions.

Abstract
Dysphagia impacts on the health and quality of life of individuals and contributes to the cost of health care. This paper summarises current literature regarding the nature, assessment and management of acquired oro-pharyngeal dysphagia in older adults. It examines the aetiology, prevalence and consequences of dysphagia, as well as issues regarding medication administration. Assessment of dysphagia is explored in terms of multidisciplinary screening, speech and language therapist clinical swallowing evaluation and instrumental assessment.

Arch Phys Med Rehabil 2015; 97:355-62. [PMID: 26606872 DOI: 10.1016/j.apmr.2015.10.104] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2015] [Revised: 10/24/2015] [Accepted: 10/27/2015] [Indexed: 12/30/2022]
Abstract
OBJECTIVE To evaluate and compare the effects of neuromuscular electrical stimulation (NMES) acting on the sensory input or motor muscle in treating patients with dysphagia with medullary infarction. DESIGN Prospective randomized controlled study. SETTING Department of physical medicine and rehabilitation. PARTICIPANTS Patients with dysphagia with medullary infarction (N=82). INTERVENTIONS Participants were randomized over 3 intervention groups: traditional swallowing therapy, sensory approach combined with traditional swallowing therapy, and motor approach combined with traditional swallowing therapy. Electrical stimulation sessions were for 20 minutes, twice a day, for 5d/wk, over a 4-week period. MAIN OUTCOME MEASURES Swallowing function was evaluated by the water swallow test and Standardized Swallowing Assessment, oral intake was evaluated by the Functional Oral Intake Scale, quality of life was evaluated by the Swallowing-Related Quality of Life (SWAL-QOL) Scale, and cognition was evaluated by the Mini-Mental State Examination (MMSE). RESULTS There were no statistically significant differences between the groups in age, sex, duration, MMSE score, or severity of the swallowing disorder (P>.05). All groups showed improved swallowing function (P≤.01); the sensory approach combined with traditional swallowing therapy group showed significantly greater improvement than the other 2 groups, and the motor approach combined with traditional swallowing therapy group showed greater improvement than the traditional swallowing therapy group (P<.05). SWAL-QOL Scale scores increased more significantly in the sensory approach combined with traditional swallowing therapy and motor approach combined with traditional swallowing therapy groups than in the traditional swallowing therapy group, and the sensory approach combined with traditional swallowing therapy and motor approach combined with traditional swallowing therapy groups showed statistically significant differences (P=.04). CONCLUSIONS NMES that targets either sensory input or motor muscle coupled with traditional therapy is conducive to recovery from dysphagia and improves quality of life for patients with dysphagia with medullary infarction. A sensory approach appears to be better than a motor approach.

Abstract
PURPOSE As the general population lives longer, the perioperative physician is more likely to encounter disease states that increase in incidence in an aging population. This review focuses on anesthetic considerations for rational drug choices during the perioperative care of elderly patients. The primary aim of the review was to identify intraoperative and postanesthetic considerations for diseases associated with advancing age; it includes highlights of the commonly impaired major organs (eg, cardiovascular, pulmonary, neurologic, renal, hepatic systems). We also outline an approach to frequent issues that arise in the immediate postsurgical period while caring for these patients. METHODS A systematic review was performed on aspects of the perioperative and postoperative periods that relate to the elderly. A list of pertinent key words was derived from the authors, and a PubMed database search was performed. FINDINGS The anesthesiologist must account for changes in various organ systems that affect perioperative care, including the cardiovascular, pulmonary, renal, hepatic, and central nervous systems. The pharmacokinetic principles frequently differ and are often unpredictable because of anatomic changes and decreased renal and hepatic function. The most important pharmacodynamic consideration is that elderly patients tend to exhibit an exaggerated hypoactivity after anesthesia. IMPLICATIONS Before surgery, it is essential to identify those patients at risk for delirium and other commonly encountered postanesthesia scenarios. Failure to manage these conditions appropriately can lead to an escalation of care and prolonged hospitalization.

Abstract
OBJECTIVES To collect information on actual nutritional intervention requirements in long-term care institutions and on the role of institutional factors in nutritional care. DESIGN A cross-sectional analysis of baseline data (collected between September 2011 and September 2013) within the context of a multicenter prospective cohort study. SETTING Nineteen long-term care institutions. PARTICIPANTS Thirteen hundred and ninety-four resident elderly (age ≥60 years). MEASUREMENTS The prevalence of nutritional derangements (MNA-Short Form) and the need to introduce nutritional interventions on the residents. RESULTS Prevalence of malnutrition and risk of malnutrition were 35.2% [95%CI, 32.8-37.8] and 52.6% [95%CI, 50.0-55.2], respectively. Malnutrition was more frequent upon admission and in larger institutions (≥50 beds). Overall, 50% of the residents requiring an individualized nutritional care plan (any type) were not receiving it. Oral diet, the use of fluid thickeners and oral nutritional supplements had to be introduced in 306 (22.5%), 201 (15%) and 175 (13%) residents, respectively. The need to implement the oral diet was mainly due to inadequacy of texture according to chewing and swallowing capabilities. In gender and age-adjusted multivariable logistic regression models, nutritional interventions were associated with worse nutritional status (P<0.001 for all). Moreover, while the duration of stay was unrelated to the need for nutritional interventions, we observed that residents living in larger long-term care institutions (≥50 beds) were more likely to require improvement in nutrition care. CONCLUSIONS In long-term care elderly residents nutritional derangements are very common, underdiagnosed and undertreated. Nutritional screening should be part of routine care. However, also the systematic involvement of a nutritional care specialist appears to be an urgent need, particularly in larger institutions where the standards of care are likely to be lower.

Abstract
RATIONALE Endotracheal intubation is associated with postextubation swallowing dysfunction, but no guidelines exist for postextubation swallowing assessments. OBJECTIVES We evaluated the prevalence, patient demographic and clinical factors, and intensive care unit (ICU) and hospital organizational factors associated with swallowing assessment after oral endotracheal intubation and mechanical ventilation in patients with acute lung injury (ALI). METHODS We performed a secondary analysis of a prospective cohort study in which investigators evaluated 178 eligible patients with ALI who were mechanically ventilated via oral endotracheal tube. The patients were recruited from 13 ICUs at four teaching hospitals in Baltimore, Maryland. Patient demographic and clinical factors, types of ICU, and hospital study sites were evaluated for their association with completion of a swallowing assessment both in the ICU and after the ICU stay before hospital discharge. Factors significantly associated with a swallow assessment were evaluated in a multivariable logistic regression model. MEASUREMENTS AND MAIN RESULTS Before hospital discharge, 79 (44%) patients completed a swallowing assessment, among whom 59 (75%) had their assessments initiated in ICU and 20 (25%) had their assessments initiated on the hospital ward. Female sex (odds ratio [OR] = 2.01; 95% confidence interval [95% CI] = 1.03-3.97), orotracheal intubation duration (OR = 1.13 per day; 95% CI = 1.05-1.22), and hospital study site (Site 3: OR = 2.41; 95% CI = 1.00-5.78) were independently associated with swallowing assessment. Although Site 3 had a twofold increase in swallowing assessments in the ICU, there was no significant difference between hospitals in the frequency of swallowing assessments completed after ICU discharge (P = 0.287) or in the proportion of patients who failed a swallowing assessment conducted in the ICU (P = 0.468) or on the ward (P = 0.746). CONCLUSIONS In this multisite prospective study, female sex, intubation duration, and hospital site were associated with postextubation swallowing assessment. These results demonstrate variability in practice patterns between institutions and highlight the need to determine the appropriate timing and indications for swallowing assessment and to more fully understand swallowing dysfunction after intubation.
