Clinical dysphagia risk predictors after prolonged orotracheal intubation

OBJECTIVES: To elucidate independent risk factors for dysphagia after prolonged orotracheal intubation. METHODS: The participants were 148 consecutive patients who underwent clinical bedside swallowing assessments from September 2009 to September 2011. All patients had received prolonged orotracheal intubations and were admitted to one of several intensive care units of a large Brazilian school hospital. The correlations between the conducted water swallow test results and dysphagia risk levels were analyzed for statistical significance. RESULTS: Of the 148 patients included in the study, 91 were male and 57 were female (mean age, 53.64 years). The univariate analysis results indicated that specific variables, including extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking, and other signs, were possible significant high-risk indicators of dysphagia onset. The multivariate analysis results indicated that cervical auscultation and coughing were independent predictive variables for high dysphagia risk. CONCLUSIONS: Patients displaying extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking and other signs should benefit from early swallowing evaluations. Additionally, early post-extubation dysfunction recognition is paramount in reducing the morbidity rate in this high-risk population.

Rehabilitative management of swallowing and oral-motor movements in patients with tetanus of a public service in Brazil.

When looking at developing countries, the prolonged intensive medical and nursing care required by many patients places extra demands on an already stretched healthcare budget. The purpose of this study was to verify the effectiveness of a systematic rehabilitative program for swallowing and oral-motor movements in intensive care unit patients with the diagnosis of tetanus. Forty-five patients who were clinically diagnosed with tetanus were included in the study. Participants were divided in two groups: GI - consisted of 18 tetanus patients who were consecutively admitted to the infectious disease ICU from January 2002 to December 2005, prior to the existence of a systematic swallowing and oral-motor intervention; GII - consisted of 27 tetanus patients who were consecutively admitted to the infectious disease ICU from January 2006 to December 2009 and were submitted to a specific rehabilitative management of swallowing and of the oral-motor movements. Results indicate that the proposed rehabilitative program reduced by approximately 50% the time patients remained in the ICU. The significant improvement observed in patients with tetanus who were submitted to the rehabilitative program for swallowing and oral-motor movements occurred in conjunction with a reduction in the amount of time necessary to reintroduce oral feeding, to decannulate and to remove the feeding tubes. In conclusion, swallowing/muscle exercise, in patients with severe/very severe tetanus, seem to promote the remission of muscle tension and seem to maximize functional swallowing.

Correlation between the severity of critically ill patients and clinical predictors of bronchial aspiration.

Objective: To determine whether the severity of non-neurological critically ill patients correlates with clinical predictors of bronchial aspiration. Methods: We evaluated adults undergoing prolonged orotracheal intubation (> 48 h) and bedside swallowing assessment within the first 48 h after extubation. We collected data regarding the risk of bronchial aspiration performed by a speech-language pathologist, whereas data regarding the functional level of swallowing were collected with the American Speech-Language-Hearing Association National Outcome Measurement System (ASHA NOMS) scale and those regarding health status were collected with the Sequential Organ Failure Assessment (SOFA). Results: The study sample comprised 150 patients. For statistical analyses, the patients were grouped by ASHA NOMS score: ASHA1 (levels 1 and 2), ASHA2 (levels 3 to 5); and ASHA3 (levels 6 and 7). In comparison with the other patients, those in the ASHA3 group were significantly younger, remained intubated for fewer days, and less severe overall clinical health status (SOFA score). The clinical predictors of bronchial aspiration that best characterized the groups were abnormal cervical auscultation findings and cough after swallowing. None of the patients in the ASHA 3 group presented with either of those signs. Conclusions: Critically ill patients 55 years of age or older who undergo prolonged orotracheal intubation (≥ 6 days), have a SOFA score ≥ 5, have a Glasgow Coma Scale score ≤ 14, and present with abnormal cervical auscultation findings or cough after swallowing should be prioritized for a full speech pathology assessment.

Avaliação e classificação da disfagia pós-extubação em pacientes críticos

OBJECTIVE to identify factors associated with dysphagia in patients undergoing prolonged orotracheal intubation (pOTI) and the post-extubation consequences. METHODS 150 patients undergoing pOTI participated in the study, evaluated according to the deglutition functional level (American Speech Language - Hearing Association National Outcome Measurement System - ASHA NOMS), severity determination (The Simplified Acute Physiology Score - SOFA) and submitted to collection of variables age, mortality, days of orotracheal intubation, number of sessions to introduce oral diet, and days to hospital discharge. We grouped patients according to ASHA classification: 1 (levels 1 and 2), 2 (levels 3, 4 and 5) and 3 (levels 6 and 7). RESULTS the variables associated with impaired deglutition functionality were age (p<0.001), mortality (p<0.003), OTI days (p=0.001), number of sessions to introduce oral diet (p<0.001) and days to hospital discharge (p=0.018). Multiple comparisons indicated significant difference between ASHA1 and ASHA2 groups in relation to ASHA3 group. ASHA1 and ASHA2 groups had a lower SOFA score when compared with the ASHA3 group (p=0.004). Only 20% of ASHA1 patients and 32% of ASHA2 patients presented safe deglutition levels before discharge. CONCLUSION factors associated with dysphagia in patients submitted to pOTI were age over 55 years and orotracheal intubation time (greater in the cases with worse deglutition functionality). The post-extubation consequences were increased mortality and length of hospital stay in the presence of dysphagia.

Screening protocol for dysphagia in adults: comparison with videofluoroscopic findings

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.
