The gag reflex and aspiration: a retrospective analysis of 120 patients assessed by videofluoroscopy

Diagnostic Accuracy of Mann Assessment of Swallowing Ability for Predicting Dysphagia in Patients with Psychiatric Disorders

Dysphagia occurs in various diseases and constitutes a major concern in patients with psychiatric disorders. The Mann Assessment of Swallowing Ability (MASA) comprises 24 clinical parameters designed to identify swallowing disorders. One item in MASA, the "gag reflex", involves an unpleasant stimulus, which means that it is often omitted when the test is administered. The aims of this study were to determine the presence/absence of dysphagia in patients with psychiatric disorders using the MASA and determine its diagnostic accuracy when the gag reflex item was excluded in patients with psychiatric disorders. The study participants comprised patients admitted to a hospital psychiatric ward in whom dysphagia had been suspected based on oral intake status. The following items were determined: age, total MASA score (23 out of 24 items, giving a score out of 195 points), body mass index score, milligram equivalents of chlorpromazine, and the Food Intake Level Scale score. The patients were divided into two groups according to the presence or absence of swallowing problems as assessed by videoendoscopic or videofluoroscopic examination. The scores for each item investigated in the MASA, including the total score, were compared between the two groups. Receiver operating characteristic curve analysis was carried out to determine the optimum cut-off value. The total MASA score, which excluded the "gag reflex" item, was lower in the problematic swallowing group than in the non-problematic swallowing group. The MASA scores for cooperation, respiratory, dysphasia, tongue coordination, oral preparation, pharyngeal phase, and pharyngeal response tended to be lower in the problematic swallowing group. Furthermore, an optimum cut-off value of 169 points (sensitivity, 0.92; specificity, 0.68; likelihood ratio, 2.84) was identified. These results indicate that the cut-off MASA score is effective in screening for dysphagia, even when the "gag reflex" item is excluded.

Questionnaire survey on pharyngolaryngeal sensation evaluation regarding dysphagia in Japan

OBJECTIVE

The objective is to conduct a questionnaire survey regarding pharyngolaryngeal sensation evaluation in dysphagia to understand the current situation in Japan.

METHOD

The questionnaire was sent to the councilor of the Society of Swallowing and Dysphagia of Japan and the Japanese Society of Dysphagia Rehabilitation-Certified Clinician. The prospective questionnaire survey included the questions listed below: Q1: What do you think of the importance of pharyngolaryngeal sensory evaluation? Q2: Select one of the essential swallowing sensations. Q3: Select one of the following regarding the frequency of sensory examination of the larynx. Q4: Select the proportion of cases the sensory test results affect. Q5: As a pharyngolaryngeal sensory evaluation method in swallowing function evaluation, please fill in the table below for the frequency, difficulty, and effectiveness of the following tests, such as gag reflex, touching the larynx by endoscopy, touching the larynx by the probe with endoscopy, cough reflex test, swallowing provocation test.

RESULTS

The essential swallowing sensations of mechanical stimulation, chemical stimulation, thermal stimulation were 84.9%, 5.4%, and 9.7%, respectively. The frequency of touching the larynx by endoscopy in the otolaryngology group and cough reflex test in dentistry was significantly higher than the other groups (p < 0.05). The correlation between the frequency and difficulty or effectiveness of the sensory tests indicated that the frequency and difficulty are significantly correlated between each item.

CONCLUSION

Our results aid in increasing understanding and selection of pharyngolaryngeal sensation evaluation for dysphagia patients.

[Guideline conform diagnostics for dysphagia : A representative survey of speech therapists at certified stroke units in Germany]

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.

The usage of overtube has a favorable effect on endoscopic submucosal dissection

BACKGROUND

Endoscopic submucosal dissection (ESD) may be very time consuming, and depending on the anesthesia, the contents of the stomach may reflux to the esophagus and cause the patient to aspirate. To prevent these situations, many practitioners suggest using an overtube, but no study has been done to evaluate the effect of the use of an overtube while performing the ESD procedure. Our aim was to investigate the effects of performing an upper gastrointestinal ESD with and without overtube.

METHODS

Records of patients who underwent ESD were evaluated for histopathological results, complications, speed of dissection, dosages of anesthetic medications, and number of suctions performed during the procedure. The patients were classified into two depending on whether an overtube was used or not.

RESULTS

There were a total of 58 patients on which 63 upper gastrointestinal ESD procedures were performed. Regarding age, gender, localization of the lesions, duration of the procedures, dosage of propofol, histopathological results, rate of complete resection, and rate of en-bloc resection, there was no difference between the two groups (p > 0,05). But the size of the lesions, the size of the resected specimen, and the speed of dissection were statistically different in two groups (p = 0.018, p < 0.001, p < 0.001, respectively).The need for suction during the procedure was much lower in the overtube group than those with no overtube (p < 0.001).

CONCLUSIONS

We conclude that using an overtube during an upper gastrointestinal ESD decreases the need for suction, favors the speed of dissection, and eases the comfort of the procedure.

Pneumonia after endoscopic resection for gastric neoplasm

BACKGROUND

Pneumonia following endoscopic procedures may affect the clinical course and prolong hospital stay.

AIM

To investigate the incidence and risk factors for pneumonia after endoscopic resection (ER) for gastric neoplasm.

METHODS

Subjects who underwent ER for gastric neoplasm at the Asan Medical Center from January 1997 to March 2013 were included. To investigate risk factors, control patients were randomly selected from these subjects.

RESULTS

Of the 7,149 subjects who underwent ER for gastric neoplasm, 44 (0.62 %) developed pneumonia. The median age of these 44 patients was 68 years (range 31-82 years), and the male to female ratio was 3:1. Twenty-five of the pneumonia patients (56.8 %) were smokers, and 8 (18.2 %) had underlying pulmonary diseases. The median procedure time was 23 min (range 2-126 min), and pathologic diagnoses included adenocarcinoma (n = 29), dysplasia (n = 10), and hyperplastic polyp (n = 5). Compared with the control group, smoking (current smoker vs. never smoker, odds ratio [OR] 2.366, p = 0.021), total procedure time (OR 1.011, p = 0.048), and hemostasis time (OR 1.026, p = 0.028) were risk factors for the development of pneumonia. In multivariate analysis, age >65 years (OR 2.073, p = 0.031), smoking (current smoker vs. never smoker, OR 2.324, p = 0.023), and hemostasis time (OR 1.025, p = 0.038) were independent risk factors. All patients recovered from pneumonia, and the duration of hospital stay did not differ between patients with pneumonia and the control group (p = 0.077).

CONCLUSIONS

Whereas old age, smoking, and longer hemostasis time are risk factors for pneumonia, its incidence after ER is not associated with clinically significant adverse outcomes.

The normal swallow: muscular and neurophysiological control

Swallowing is a complex physiologic function that involves precisely coordinated movements within the oral cavity, pharynx, larynx, and esophagus. This article reviews the anatomy, muscular control, and neurophysiological control of normal, healthy swallowing.

[Dysphagia screening on resumption of oral intake in inpatients predictive factor for the resumption of oral intake]

There is much concern about the acute phase of restarting an oral diet for hospital inpatients who have been prohibited from any oral intake. We found predictive factors for the successful resumption of oral intake in such patients. A total of 186 subjects who had been hospitalized without oral intake were screened for dysphagia between January 1st and December 31st in 2010 (mean age 80.9 years), and formed the study population. We observed them from the initial consultation day until the discharge. (mean days 32.6) We examined factors of age, sex, appetite, gag reflex, tongue activity, the repetitive saliva swallowing test (RSST), obeying commands, the status of the laryngopharynx, laryngeal sensation and the 3 ml water swallowing test under endoscopy. We excluded those who died in hospital after dysphagia screening because they were obviously lost to follow-up. One hundred and twelve patients (60.2%) could resume oral intake, 54 patients could not and 20 (10.8%) died. Logistic regression analysis identified seven significant factors in predicting the resumption of oral intake : 1) age (p = 0.01, OR = 0.938, 95% CI 0.903-0.976); 2) sex (p = 0.21, OR = 2.15, 95% CI 1.124-4.128); 3) appetite (p = 0.041, OR = 1.983, 95% CI 1.029-3.821); 4) gag reflex (p = 0.06, OR = 1.932, 95% CI 0.971-3.844); 5) tongue activity (P = 0.002, OR = 3.825, 95% CI 1.647-8.883); 6) RSST (P = 0.013, OR = 2.284, 95% CI 1.186-4.397); 7) obeying commands (p = 0.02, OR = 3.005, 95% CI 1.507-5.993); 8) the status of the laryngopharynx (P = 0.668, OR = 0.668, 95% CI 0.351-1.272); 9) laryngeal sensation (P = 0.081, OR = 1.841, 95% CI 0.928-3.650); and the 3 ml water swallowing test under endoscopy (P = 0.000, OR = 0.226, 95% CI 0.102-0.499). These predictive factors could be very useful for dysphagia screening to help forecast the successful resumption of oral intake in affected patients. When the likelihood of dysphagia and the onset of aspiration pneumonia are suggested by dysphagia screening, these factors must be taken into careful consideration when oral intake is to be resumed.

Sedation methods can determine performance of endoscopic submucosal dissection in patients with gastric neoplasia

BACKGROUND

Although proper sedation is mandatory for endoscopic procedures such as endoscopic submucosal dissection (ESD), there is no research investigating the effects of sedation on ESD performance and complications. We aimed to evaluate the relationship among sedation methods, clinical outcomes, and complications after ESD for gastric neoplasia.

METHODS

We retrospectively reviewed clinical data of 1,367 patients with 1,485 lesions who had undergone ESD for gastric adenoma or early gastric cancer at our tertiary teaching hospital in Seoul, Korea, between January 2008 and May 2011. Of these, 1,035 lesions in 958 patients were included in the intermittent midazolam/propofol injection by endoscopists (IMIE) group, and 450 lesions in 409 patients were included in the continuous propofol infusion with opioid administration by anesthesiologists (CPIA) group.

RESULTS

En bloc resection and complete resection rates were higher in the CPIA group than in the IMIE group (CPIA vs. IMIE; en bloc resection, 99.8 and 95.0 %, P < 0.001; complete resection, 94.2 and 88.3 %, P < 0.001). Duration of procedure was shorter in the CPIA group than in the IMIE group (CPIA vs. IMIE; 48.2 ± 32.5 and 57.6 ± 41.3 min, P < 0.001). In multivariate analysis, sedation method was an independent factor associated with en bloc resection and complete resection. Additionally, sedation with CPIA was not a risk factor for bleeding (P = 0.403) or perforation (P = 0.474); however, aspiration pneumonia developed more frequently in patients sedated with CPIA (CPIA vs. IMIE, 4.4 and 1.5 %, P = 0.002).

CONCLUSIONS

Sedation with CPIA can improve ESD performance.

Risk factors and prognosis of pulmonary complications after endoscopic submucosal dissection for gastric neoplasia

BACKGROUND

Hospital-acquired pneumonia after an endoscopic submucosal dissection (ESD) can prolong the patient's stay in the hospital, leading to greater healthcare costs. However, little is known of the characteristics and risk factors associated with this complication.

AIMS

To analyze the clinical features of pneumonia after ESD and to suggest a treatment plan.

METHODS

This was a retrospective study in which the cases of 1,661 consecutive patients who underwent ESD for 1,725 lesions between January 2008 and June 2011 were reviewed.

RESULTS

Of the 1,661 patients who underwent ESD during the study period, 38 were subsequently diagnosed with pneumonia, and an additional 18 patients exhibited lung consolidation, based on chest radiography, without respiratory signs or symptoms. The remaining 1,605 patients showed neither lung consolidation on chest radiography nor respiratory signs/symptoms. Continuous propofol infusion with intermittent or continuous administration of an opioid [odds ratio (OR) 4.498, 95 % confidence interval (CI) 2.267-8.923], a procedure time of >2 h (OR 2.900, 95 % CI 1.307-6.439), male gender (OR 2.835, 95 % CI 1.164-6.909), and age >75 years (OR 2.765, 95 % CI 1.224-6.249) were independent risk factors for pneumonia after ESD. In patients with only lung consolidation (without respiratory signs and symptoms), the length of hospital stay and prognosis were not affected by antibiotics use.

CONCLUSIONS

Deep sedation under continuous propofol infusion with opioid injection during ESD may be a risk factor for pneumonia.

Cryostimulation improves recovery from oropharyngeal dysphagia after stroke

Introduction: Stroke is considered one of the most frequent neurological causes of oropharyngeal dysphagia.

Aim: To determine the effect of cryostimulation on oropharyngeal sensitivity and, subsequently, on the swallowing reaction and premature escape of food in patients with neurogenic dysphagia after stroke.

Methods: Clinical and experimental study. The study enrolled 7 adult subjects, 6 men and 1 woman ranging from 28 to 64 years of age, with a diagnosis of stroke and current oropharyngeal dysphagia without any other underlying disease. The selected subjects underwent speech-language pathology evaluation and videofluoroscopic assessment of the dysphagia. The subjects were then treated with cryostimulation consisting of 10 applications to each structure (anterior faucial pillar, posterior oropharyngeal wall, soft palate, and back tongue) 3 times a day (for a total of 30 daily applications per structure) for 4 consecutive days. The patients were then re-evaluated based on the same criteria. The pre- and post-cryostimulation results of the clinical and videofluoroscopic evaluations were analyzed descriptively and statistically using Student's t-test and Fisher's exact test.

Results: Cryostimulation had beneficial effects on oropharyngeal sensitivity in 6 of the 7 subjects. There was also a significant improvement in swallowing and in the premature escape in six subjects.

Conclusion: Cryostimulation increased sensitivity and subsequently improved the swallowing reaction and premature escape of food in patients with neurogenic dysphagia after stroke. These effects were evident by both speech-language pathology and videofluoroscopic evaluation.

Oropharyngeal dysphagia in long-term care: misperceptions of treatment efficacy

The assessment and management of patients in long-term care who have oropharyngeal dysphagia has developed into an apparently complex and distinct field of practice. It is unfortunate that it lacks an evidence base, the efficacy of treatment is not established, and many clinicians are unfamiliar with appropriate and effective interventions because of a lack of training. Some commonly used interventions are not only ineffective but potentially hazardous. Physicians must become more familiar with the assessment process and appropriate management.

Postoperative acute respiratory insufficiency following adenotonsillectomy in children with neuropathy

OBJECTIVE

Evaluate the incidence of acute respiratory insufficiency (ARI) in the immediate postoperative period following adenotonsillectomy in children with neurological diseases.

METHODS

Medical records from all pediatric adenotonsillectomies performed from January 1997 through August 2003 at the Roberto de Abreu Sodré Hospital of the Association for the Welfare of Physically Handicapped Children (AACD) in São Paulo were reviewed. Data were collected for patient age, neurological diagnosis, associated comorbidities, index of respiratory insufficiency in the immediate postoperative period and period of hospitalization.

RESULTS

One hundred and nine patients charts had sufficient documentation to be included in this study. Of these, 15 (13.7%) developed ARI in the immediate postoperative period. Ages ranged from 1 to 12 years old (average of 5). Of the 15 patients that presented ARI, 10 (67%) were intubated in the first 3h following extubation. The predominant neurological diagnosis was non-progressive chronic encephalopathy, observed in 84 children (77%), and, among that, 14 (17%) presented ARI. Other neurological diagnoses present in this study were Rett syndrome, neuromuscular disease and meningomyelocele. All of the children that developed ARI presented quadriplegia. Among children that did not develop ARI, the predominant motor pattern was: 28 with quadriplegia, 38 diplegia, 10 hemiplegia, 12 with involuntary movement (choeroathethosis) and six without motor involvement. Children presenting ARI needed mechanical ventilation for an average of 37.87 h (1.5 days) in the intensive care unit. ARI increased the period of hospitalization; these children had an average length of stay of 7 days versus 1.5 days for those that did not develop complications.

CONCLUSION

Children with neurological disorders, especially those with quadriplegic pattern of motor involvement and severe oropharyngeal dysphagia, are at higher risk for respiratory insufficiency in immediate postoperative period of adenotonsillectomy and should be observed in intensive care unit.

Adult Dysphagia Assessment in the UK and Ireland: Are SLTs Assessing the Same Factors?

This is the first study to examine dysphagia assessment practices of UK/Ireland speech and language therapists. The aims were to (1) examine practice patterns across clinicians, (2) determine levels of consistency in practice, and (3) compare practices of clinicians in the UK/Ireland with those previously reported of clinicians in the United States. A questionnaire, developed for earlier U.S. research, was adapted following a pilot study. The resulting email survey was completed by 296 speech and language therapists working with dysphagic adults. Respondents were asked to rate how frequently they use 31 components of a clinical dysphagia examination. Consistency was determined by calculating the percentage of respondents who agreed on frequency of use. Low frequency of use was reported for four components: trials with compensatory techniques, obtain patient's drug history, assessment of speech articulation/intelligibility, and screening/assessment of mental abilities. Variability among clinicians was high, with inconsistency observed for 6/31 components (19%) and high consistency for only 10/31 (32%). Results were compared with data from the earlier U.S. study. Notable differences in practice were observed for five components: cervical auscultation, trials with compensatory techniques, gag reflex, assessment of sensory function, and screening/assessment of mental abilities. Inconsistency among UK/Ireland clinicians was higher than in the comparator U.S. study. The clinical implications of these findings are discussed.

Deglutição e envelhecimento: enfoque nas manobras facilitadoras e posturais utilizadas na reabilitação do paciente disfágico

Resumo O propósito deste artigo é apresentar uma revisão de literatura sobre as manobras utilizadas na reabilitação das disfagias. O aumento da população idosa acarreta maior prevalência de doenças neurológicas que cursam com quadro de disfagia, o que reforça a necessidade de estudos sobre o tema. Esse fato vem despertando atenção de profissionais que atuam na reabilitação, em especial a fonoaudiologia. Dentro da reabilitação encontramos manobras facilitadoras e posturais que podem proporcionar maior segurança alimentar. Baseados na literatura, observamos que as manobras facilitadoras supraglótica, supersupraglótica e de esforço ajudam na proteção da via aérea através da técnica do controle da apnéia confortável, tendo como propósito a segurança alimentar do paciente disfágico. As manobras posturais de cabeça para baixo, cabeça para trás, rotação de cabeça para o lado comprometido e cabeça inclinada para o lado bom mostraram ter como propósito o fechamento do vestíbulo laríngeo, reduzir a distância hio-laríngea e a drenagem gravitacional do alimento em direção à faringe. Assim sendo, o estudo da dinâmica da deglutição através do método videofluoroscópico e o conhecimento, por parte dos profissionais, das diferentes manobras e suas complicações clínicas, mostraram ser importantes para a reabilitação do paciente idoso disfágico.

Is the gag reflex useful in the management of swallowing problems in acute stroke?

The goal of this study was to compare the diagnostic value of an absent gag reflex in acute stroke patients with the bedside swallowing assessment (BSA) and assess its relationship to outcomes. Two hundred forty-two acute stroke patients had their gag reflex tested and a BSA performed. Numbers needing nasogastric or gastrostomy tube insertion were noted, also their discharge destination, discharge Barthel Index, and mortality. The mean age of the subjects was 76.5+/-10.2 years; 37.6% were male; 41.7% of the patients were dysphagic on BSA; 18.2% had an absent gag. Dysphagia was present in 88.6% of the patients with an absent gag and in 31.3% of those with an intact gag. The gag reflex was absent in 38.6% of dysphagic and 3.5% of nondysphagic patients. Comparing an absent gag against the criterion of the BSA, its specificity was 0.96, sensitivity 0.39, positive predictive value 0.89, and negative predictive value 0.69. Regression analyses found that an intact gag gave an Odds Ratio [CI] of 0.23 [0.06-0.91] for gastrostomy feeding but did not predict other outcomes. We conclude that the gag reflex is as specific as but less sensitive than the BSA in detecting dysphagia in acute stroke patients. An intact gag may be protective against longer-term swallowing problems and the need for enteral feeding.

Predictors and consequences of pneumonia in critically ill patients with stroke

OBJECTIVE

Ascertain the incidence, predictors and consequences of early (within 48 hours of admission) and nosocomial pneumonia among critically ill patients with stroke.

METHODS

Medical records of critically ill patients with acute stroke were reviewed. Predictors and consequences of pneumonia were determined with analysis of variance.

RESULTS

55 patients, aged 33 to 91 (median 74) years, were admitted. The stroke was located at the brainstem in 14 (26.4%) patients. Nine patients (16.4%) had early pneumonia and additional 17 patients (30.9%) developed nosocomial pneumonia. Patients with brain-stem stroke were more likely to develop early pneumonia (p =.04). Nosocomial pneumonia incidence was higher in patients who failed swallowing evaluation (RR = 6.3, 95% CI: 0.9-43.0) and in those who were intubated (58.6% v 0%, p =.00008). Also, nosocomial pneumonia was associated with longer duration of mechanical ventilation and prolonged hospital stay. Nineteen patients (34.5%) died at the hospital. They were more likely to be older (median 77 versus 69 years, p =.03) with higher admission acuity of illness.

CONCLUSION

Pneumonia complicated stroke in 47% of critically ill patients and adversely impacted the duration of mechanical ventilation and overall length of hospital stay. Aggressive preventive measures are needed to reduce pneumonia occurrence in stroke patients.

[Clinical and videofluoroscopic evaluation of deglutition in children with tetraparetic spastic cerebral palsy]

Cerebral palsy is a condition that may be associated with swallowing disorders, that is, oropharingeal dysphagia. The aim of this study was to characterize and compare the swallowing processes of 32 children with this condition, by clinical and videofluoroscopic evaluation, with special focus on tracheal aspiration detectability. Results show an important compromise of oral phase. The most important findings during the pharyngeal phase were velopharingeal incompetence and residuals on the pharyngeal recesses. Aspiration was more common with liquids, before and after deglutition. On clinical and videofluoroscopic evaluation, cervical hyperextension was the commonest postural abnormality. Videofluoroscopy confirmed the occurrence of aspiration on most of the cases that presented suggestive signs of aspiration during clinical evaluation. We conclude that clinical and videofluoroscopic evaluations are complementary on deglutition evaluation and together may point to the most specific rehabilitation procedure.

Dysphagia: the management and detection of a disabling problem

Dysphagia represents a varying group of swallowing difficulties commonly encountered in patients in both acute and community settings. It accompanies a variety of disease states, can be neuromuscular or mechanical/obstructive in origin and encompasses varied prognoses and outcomes. Its consequences include dehydration, malnutrition, bronchospasm, airways obstruction, aspiration pneumonia and chronic chest infection, social isolation, depression and detrimental psychosocial effects. Current "best evidence" in screening, assessment and management is of variable quality but demonstrates that nurses have an important role to play in interventions entailing multiprofessional collaboration within individually tailored programmes. Clear benefits for patients have been indicated. There are gaps in the knowledge base, especially in relation to psychosocial effects and treatment strategies and the nursing contribution in this area.

Screening swallowing function of patients with acute stroke. Part one: Identification, implementation and initial evaluation of a screening tool for use by nurses

Stroke is a major cause of acute and chronic disability in the developed world, producing a wide range of impairments, including dysphagia, which impact upon eating. Dysphagia affects between one and two thirds of patients with acute stroke, with the potential for life-threatening airway obstruction, aspiration pneumonia and malnutrition. Whilst associated with increased impairment, dysphagia may present in isolation or accompanied by minimal disability; universal screening of swallowing function is recommended. This study describes the process undertaken to review the evidence for dysphagia screening methods in patients with acute stroke. It also identifies, implements and establishes sensitivity and specificity of a screening tool (the Standardized Swallowing Assessment, SSA) for use by nurses. Not all ward staff had completed training to use the SSA by conclusion of the patient audit. Nonetheless 123 out of 165 assessable patients (74.5%) had their swallow function screened, 64 by SSA (52%). Based on 68 completed screening episodes by independently competent nurses, a comparison with summative clinical judgement of swallow function revealed a sensitivity of 0.97 and specificity of 0.9 for detection of dysphagia, with positive and negative predictive values of 0.92 and 0.96. This was significantly better than gag reflex performance, supporting the use of the SSA by competent ward nurses.
