Abstract
PURPOSE The purpose of the present study was to characterize the differences between respiration and swallowing in patients with dysphagia after cervical spinal cord injury (CSCI) and to explore the underlying physiological changes. METHOD A total of 95 participants were recruited for bedside swallowing evaluation followed by a flexible endoscopic evaluation of swallowing and surface electromyography with a thermocouple nasal airflow sensor examination: 32 with dysphagia, 33 without dysphagia, and 30 healthy controls. The differences in respiratory patterns, swallowing apnea duration (SAD), inspiratory-expiratory ratio, and swallowing efficiency were observed among healthy adults, CSCI patients with and without dysphagia after CSCI. RESULTS Compared with those of healthy controls and patients without dysphagia after CSCI, the postswallow respiratory pattern of patients with dysphagia after CSCI was an inspiratory pattern, and the SAD was significantly shorter in patients with dysphagia after CSCI (p < .001). Additionally, the expiratory time in patients with dysphagia was significantly shorter than the inspiratory time, and the swallowing efficiency was reduced, requiring multiple swallows. Moreover, the index of SAD was statistically significant for predicting the development of dysphagia in patients with CSCI (p < .001). CONCLUSION Patients with CSCI have an inspiratory pattern after swallowing, and the SAD is significantly reduced; SAD can be used as the predictor of dysphagia in patients after CSCI; the pattern of coordination between respiration and swallowing in patients with dysphagia after CSCI is different from that of healthy controls and patients without dysphagia after CSCI.

Abstract
Introduction Dysphagia is a common complication in patients with cervical spinal cord injury (C-SCI) and can cause various pulmonary complications, such as aspiration pneumonia and mechanical airway obstruction increasing mortality and morbidity. This study evaluated the clinical factors that predict dysphagia in patients with traumatic and non-traumatic C-SCI. Methods Ninety-eight patients with C-SCI were retrospectively enrolled in this study and were divided into those with and without dysphagia. Clinical factors such as age, sex, tracheostomy, spinal cord independence measure, pulmonary function test (PFT) including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and FVC/FEV1, American Spinal Cord Injury Association score, Berg Balance Scale, and surgical approach were investigated retrospectively. Results Multivariate logistic regression analysis revealed that FVC and the presence of tracheostomy were significantly correlated with dysphagia in patients with C-SCI (p < 0.05). FVC and the presence of tracheostomy are useful tools for detecting dysphagia in patients with C-SCI. Conclusion Considering the results of our study, early PFTs, especially FVC, in patients with C-SCI and early initiation of dysphagia management and treatment in patients with C-SCI and tracheostomy will be advantageous in lowering the mortality and morbidity due to pulmonary aspiration in these patients.

Abstract
OBJECTIVES To elucidate the incidence and risk factors for pneumonia after acute traumatic cervical spinal cord injury (CSCI). DESIGN Retrospective cohort study.Setting: Spinal injuries center in Japan.Participants: Of 184 individuals who were admitted within 2 weeks after acute traumatic cervical spinal injuries, 167 individuals who met the criteria were included in this study.Interventions: The occurrence of pneumonia, degree of dysphagia using the Dysphagia Severity Scale, patient age, history of smoking, presence of tracheostomy, vital capacity, level of injury, and the American Spinal Injury Association Impairment Scale (AIS) 2 weeks after injury were assessed.Outcomes: Incidence of pneumonia were analyzed. Moreover, the risk factors of pneumonia were evaluated using logistic regression analysis. RESULTS From the 167 individuals who met the criteria, 30 individuals (18%) had pneumonia; in 26 (87%) of these individuals, pneumonia was aspiration related, defined as Dysphagia Severity Scale ≤ 4. The median occurrence of aspiration pneumonia was 11.5 days after injury. A logistic regression analysis revealed that severe AIS and severe Dysphagia Severity Scale scores were significant risk factors of pneumonia after CSCI. CONCLUSIONS It was highly likely that the pneumonias following CSCI were related to aspiration based on the Dysphagia Severity Scale. In addition, most of the patients developed aspiration pneumonia within 1 month after injury. Aspiration and severe paralysis were significant risk factors for pneumonia. The treatment of dysphagia in the acute phase should be considered an important indicator to prevent pneumonia.

Abstract
INTRODUCTION Early detection and management of dysphagia are essential for preventing aspiration pneumonia and reducing mortality in patients with cervical spinal cord injury (C-SCI). In this study, we identified risk factors for dysphagia in patients with C-SCI by analyzing the correlation between the clinical factors and the severity of dysphagia, not the presence or absence of dysphagia. Combined with the analysis results of previous studies, we thought that this additional analysis method could more accurately reveal the risk factors for dysphagia in patients with C-SCI. METHODS The presence and severity of dysphagia in patients with C-SCI was evaluated using a modified videofluoroscopic dysphagia scale (mVDS) and penetration-aspiration scale (PAS). All included patients with C-SCI performed a video fluoroscopic swallowing study (VFSS). Clinical factors such as age, sex, the presence of tracheostomy, spinal cord independence measure (SCIM), pulmonary function test (PFT), including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FVC/FEV1, maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP), American Spinal Cord Injury Association (ASIA) score, Berg Balance Scale (BBS), and operation method were investigated. RESULTS In the multivariate regression analysis, the anterior surgical approach was the only clinical factor that had a significant correlation in both mVDS and PAS, which represents the severity of dysphagia in C-SCI patients (p < 0.05). CONCLUSION The anterior surgical approach was correlated with the severity of dysphagia in patients with C-SCI. Considering this, as one of the risk factors affecting dysphagia in patients with C-SCI, surgical method may also need to be considered. Additionally, we recommend that clinicians should pay particular attention to the potential for development of dysphagia in patients who received anterior cervical surgery. However, further prospective studies with larger sample sizes are needed for more accurate generalization.

Abstract
BACKGROUND Despite the fact that weaning from mechanical ventilation (MV) is one of the main rehabilitation goals in patients with spinal cord injury (SCI), controversies are still open about the optimal rehabilitation approach. OBJECTIVE This systematic review aimed at characterizing the rehabilitation interventions currently available to optimize weaning from MV in SCI patients. METHODS On April 12nd, 2022, a systematic literature search was performed in PubMed, Scopus, Web of Science, Cochrane, and PEDro, identifying studies assessing MV patients with SCI undergoing pulmonary rehabilitation. The primary outcomes were weaning duration, MV duration, and weaning success rate. Secondary outcomes were pulmonary function, extubation or decannulation time, length of stay, and safety. RESULTS Out of 413 records, 14 studies were included (2 randomized controlled trials, 7 observational studies, and 5 case reports). Most of the studies assessed a comprehensive rehabilitation approach, including high tidal volume ventilation, positioning, mechanical lung recruitment maneuvers, secretion management strategies, respiratory muscle training, and electrical stimulation. CONCLUSION Our findings suggested that a comprehensive rehabilitation intervention might have a role in reducing MV duration in patients with SCI. Further studies are needed to better characterize the optimal rehabilitation strategies for enhancing functional recovery of patients with SCI.

Abstract
Despite centuries of investigation, questions and controversies remain regarding the fundamental genesis and motor pattern of swallow. Two significant topics include inspiratory muscle activity during swallow (Schluckatmung, i.e., "swallow-breath") and anatomical boundaries of the swallow pattern generator. We discuss the long history of reports regarding the presence or absence of Schluckatmung and the possible advantages of and neural basis for such activity, leading to current theories and novel experimental directions.

Abstract
Videofluoroscopic analyses of swallowing in survivors of traumatic cervical spinal cord injury (tCSCI) have been largely limited to case reports/series and qualitative observations. To elucidate the disrupted physiology specifically underlying dysphagia post-tCSCI, this prospective observational study analyzed videofluoroscopic swallow studies (recorded at 30 frames per second) across 20 tCSCI survivors. Norm-referenced measures of swallow timing or displacement, and calibrated area measures of laryngeal vestibule closure (LVC) were explored in relation to the severity of aspiration or pharyngeal residue. Videofluoroscopic performance was compared by injury level, surgical intervention, tracheostomy status, and in relation to clinical bedside assessments. Reduced pharyngeal constriction, delayed hyoid elevation, and impaired LVC characterized post-tCSCI dysphagia. Reduced extent of hyoid excursion and of pharyngoesophageal segment (PES) opening were not as prominent, only present in approximately half or less of the sample. Ten participants aspirated and 94% of aspiration events were silent. Severity of aspiration significantly correlated with pharyngeal constriction and prolonged pharyngeal transit times. Post-swallow residue correlated with delayed PES distention/closure and prolonged pharyngeal transit. Clinical inference regarding the integrity of the pharyngeal phase at bedside was limited; however, EAT-10 scores demonstrated promise as an adjuvant clinical marker of post-tCSCI dysphagia. This exploratory study further describes the pathophysiology underlying post-tCSCI dysphagia to promote deficit-specific rehabilitation and functional recovery.

Abstract
PURPOSE International multi-professional expert consensus was sought to develop best practice recommendations for clinical management of patients following cervical spinal cord injury with oropharyngeal dysphagia and associated complications. Additionally, risk factors for dysphagia were identified to support the development of a screening tool. MATERIALS AND METHODS A two-round Delphi study was undertaken with a 27-member panel of expert professionals in cervical spinal cord injury and complex dysphagia. They rated 85 statements across seven topic areas in round one, using a five-point Likert scale with a consensus set at 70%. Statements not achieving consensus were revised for the second round. Comparative group and individual feedback were provided at the end of each round. RESULTS Consensus was achieved for 50 (59%) statements in round one and a further 12 (48%) statements in round two. Recommendations for best practice were agreed for management of swallowing, respiratory function, communication, nutrition and oral care. Twelve risk factors for dysphagia were identified for components of a screening tool. CONCLUSIONS Best practice recommendations support wider clinical management to prevent complications and direct specialist care. Screening for risk factors allows early dysphagia identification with the potential to improve clinical outcomes. Further evaluation of the impact of these recommendations is needed.Implications for RehabilitationDysphagia is an added complication following cervical spinal cord injury (cSCI) affecting morbidity, mortality and quality of life.Early identification of dysphagia risk allows focused interventions that reduce associated nutritional and respiratory impairments.Best practice recommendations based on expert consensus provide a baseline of appropriate interventions, in the absence of empirical evidence.A multi-professional approach to rehabilitation encourages a consistent and coordinated approach to care across acute and rehabilitation settings.

Abstract
AbstractDysphagia (swallowing impairment) is a frequent complication of cervical spinal cord injury (cSCI). Recently published national guidance in the UK on rehabilitation after traumatic injury confirmed that people with cSCI are at risk for dysphagia and require early evaluation while remaining nil by mouth [National Institute for Health and Care Excellence. Rehabilitation after traumatic injury (NG211), 2022, https://www.nice.org.uk/guidance/ng21]. While the pathogenesis and pathophysiology of dysphagia in cSCI remains unclear, numerous risk factors have been identified in the literature. This review aims to summarize the literature on the risk factors, presentation, assessment, and management of dysphagia in patients with cSCI. A bespoke approach to dysphagia management, that accounts for the multiple system impairment in cSCI, is presented; the overarching aim of which is to support effective management of dysphagia in patients with cSCI to prevent adverse clinical consequences.

Abstract
Laryngeal function is vital to airway protection. While swallow is mediated by the brainstem, mechanisms underlying increased risk of dysphagia after cervical spinal cord injury (SCI) are unknown. We hypothesized that loss of descending phrenic drive affects swallow and breathing differently, and loss of ascending spinal afferent information alters swallow regulation. We recorded electromyograms from upper airway and chest wall muscles in freely breathing pentobarbital-anesthetized cats and rats. Inspiratory laryngeal activity increased ~two-fold following C2 lateral-hemisection. Ipsilateral to the injury, crural diaphragm EMG amplitude was reduced during breathing (62 ± 25% change post-injury), but no animal had complete termination of activity; 75% of animals increased contralateral diaphragm recruitment, but this did not reach significance. During swallow, laryngeal adductor and pharyngeal constrictor muscles increased activity, and diaphragm activity was bilaterally suppressed. This was unexpected because of the ipsilateral-specific response during breathing. Swallow-breathing coordination was also disrupted and more swallows occurred during early expiration. Finally, to determine if the chest wall is a major source of feedback for laryngeal regulation, we performed T1 total transections in rats. As in the C2 lateral-hemisection, inspiratory laryngeal recruitment was the first feature noted. In contrast to the C2 lateral-hemisection, diaphragmatic drive increased after T1 transection. Overall, we found that SCI alters laryngeal drive during swallow and breathing, and reduced swallow-related diaphragm activity. Our results show behavior-specific effects, suggesting SCI affects swallow more than breathing, and emphasizes the need for additional studies on the effects of ascending afferents from the spinal cord on laryngeal function.

Abstract
Objective To utilize pulmonary function parameters as predictive factors for dysphagia in individuals with cervical spinal cord injuries (CSCIs). Methods Medical records of 78 individuals with CSCIs were retrospectively reviewed. The pulmonary function was evaluated using spirometry and peak flow meter, whereas the swallowing function was assessed using a videofluoroscopic swallowing study. Participants were divided into the non-penetration-aspiration group (score 1 on the Penetration-Aspiration Scale [PAS]) and penetration-aspiration group (scores 2–8 on the PAS). Individuals with pharyngeal residue grade scores >1 were included in the pharyngeal residue group. Results The mean age was significantly higher in the penetration-aspiration and pharyngeal residue groups. In this study, individuals with clinical features, such as advanced age, history of tracheostomy, anterior surgical approach, and higher neurological level of injury, had significantly more penetration-aspiration or pharyngeal residue. Individuals in the penetration-aspiration group had significantly lower peak cough flow (PCF) levels. Individuals in the pharyngeal residue group had a significantly lower forced expiratory volume in 1 second (FEV1). According to the receiver operating characteristic curve analysis of PCF and FEV1 on the PAS, the cutoff value was 140 L/min and 37.5% of the predicted value, respectively. Conclusion Low PCF and FEV1 values may predict the risk of dysphagia in individuals with CSCIs. In these individuals, active evaluation of swallowing is recommended to confirm dysphagia.

Abstract
Context/objective: Swallowing difficulties (dysphagia) are well recognized after spinal injury. There are no published rehabilitation efficacy studies to date. This study explored viability and outcomes of swallowing rehabilitation programs for four patients with persisting dysphagia.Design: Prospective, quantitative experimental longitudinal case series.Setting: Spinal rehabilitation unit or patients' homes.Interventions: Four patients engaged in a 6-week (3×weekly) individualized progressive rehabilitation program.Outcome measures: Objective videofluoroscopic measures of timing and displacement and a validated self-reported questionnaire - the Eating Assessment Tool (EAT-10) were taken pre-therapy, immediately post-therapy and EAT-10 was repeated at 3 months. Feeling and fatigue scale scores were taken before and after each therapy session.Results: Patients (63, 67 yr, 67 yr, 76 yr; 3 male) had varying spinal diagnoses (2 traumatic, all involving the C-spine) and length of dysphagia (6 weeks, 6 weeks, 12 weeks, 10 yr). Common physiological impairments across all patients were: reduced maximum hyoid displacement, reduced pharyngeal constriction and reduced pharyngoesophageal segment maximum opening. Therapy programs were well received with 100% compliance. Participants made quantitative improvements in their videofluoroscopic measures of timing and displacement. Three out of four participants were able to have their percutaneous endoscopic gastrostomies (PEG) removed. EAT-10 scores significantly improved for all patients (P < .001). Poor upper limb function and restricted neck flexion prohibited some exercises.Conclusions: For many patients following spinal injury, dysphagia resolves during the acute phase of post-surgery recovery. For some, significant pharyngeal impairments persist. This case series demonstrates potential to regain functional swallowing following a 6-week tailored rehabilitation program. High-quality research exploring efficacy of rehabilitation programs are warranted.

Coutts KA. Dysphagia in cervical spinal cord injury: How international literature trends can guide South African practice patterns - A scoping review. SOUTH AFRICAN JOURNAL OF PHYSIOTHERAPY 2021; 77:1542. [PMID: 34192210 PMCID: PMC8182465 DOI: 10.4102/sajp.v77i1.1542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 02/15/2021] [Indexed: 11/01/2022] Open
Abstract
Background The limited data regarding dysphagia in high-level spinal cord injuries (SCIs) stem from economically developed countries. Dysphagia is prevalent in patients with cervical SCI; however, in a South African context, speech-language pathologists (SLPs) are not seen as key when managing this population. This may result in patients not being screened or identified early, leading to possible complications. The literature could provide useful insight on how best to address this clinical gap. Objectives The aim of my study was to conduct a scoping review on the description of dysphagia, the risk factors for developing dysphagia post-SCI and the practice patterns of team members working with dysphagia in cervical SCIs. Methods A five-step scoping review was undertaken. Data were analysed by using descriptive statistics as well as a thematic analysis by using a top-down approach. Results Through the process of screening according to the inclusion and exclusion criteria, 25 articles were included. Primarily, the pharyngeal phase was affected, which can lead to an aspiration pneumonia. The key risk factors were the presence of a tracheostomy tube, the use of ventilation and anterior spinal cord surgery. There was little mention regarding specific practice patterns, but an interdisciplinary approach was suggested as the most efficient model. Conclusions Specific guidelines and management options need to be considered for a South African context, given the high incidence of trauma-related injuries. There needs to be locally produced research, providing suggestions on how different team members can screen and identify dysphagia within this population. Solutions need to be unique, and contextually responsive and appropriate. Clinical implications The team members and the roles of these different team members need to be re-examined in order to ensure the early identification and management of cervical SCI patients who are at risk of developing a dysphagia.

Abstract
BACKGROUND Individuals with acute cervical spinal cord injury require specialised interventions to ensure optimal clinical outcomes especially for respiratory, swallowing and communication impairments. This study explores the experiences of post-injury care for individuals with cervical spinal cord injury and their family members during admissions in specialised and non-specialised units in the United Kingdom. METHODS Semi-structured interviews were undertaken with individuals with a cervical spinal cord injury and their family member, focussing on the experience of care across units. Eight people with spinal cord injury levels from C2 to C6, were interviewed in their current care settings. Six participants had family members present to support them. Interviews were audio-recorded and transcribed with data inputted into NVivo for thematic analysis. RESULTS The study identified six themes from the participant interviews that highlighted different experiences of care in non-specialised and specialised settings. A number of these were related to challenges with the system, whilst others were about the personal journey of recovery. The themes were titled as: adjustment, transitions, "the golden opportunity", "when you can't eat", communication, and "in the hands of the nurses and doctors". CONCLUSIONS Whilst participants reported being well cared for in non-specialised units, they felt that they did not receive specialist care and this delayed their rehabilitation. Participants were dependent on healthcare professionals for information and care and at times lost hope for recovery. Staff in non-specialised units require training and guidance to help provide support for those with dysphagia and communication difficulties, as well as reassurance to patients and families whilst they wait for transfer to specialised units.

Abstract
Objective The objectives of this study were to clarify whether prevertebral soft tissue (PVST) thickening increases the risk of dysphagia, to identify at which vertebral level determining PVST thickness is useful, and to determine cutoff values. Methods A total of 80 patients with traumatic cervical spinal cord injury (TCSCI) treated over a 43-month period at a single regional institution specializing in cervical spinal cord injuries participated in the study. The exclusion criteria were having undergone anterior cervical spine surgery; a history of complicated traumatic brain injury, complicated vertebral artery injury, or brain injury; endotracheal intubation at day 30 after onset; the disappearance of neurological symptoms within 24 hours after onset; and the use of a halo vest. The associations between PVST thicknesses at C1, C2, C3, C6, and C7 measured by CT on the day of onset and the presence of dysphagia (Food Intake LEVEL Scale score <8) at 30 and 60 days after onset of TCSCI were analyzed using ROC curves to calculate the maximum area under the curve and the PVST cutoff values for these vertebrae. Associations between various risk factors, including PVST thickness, and dysphagia at days 30 and 60 after onset were examined using univariate and multivariate analyses. Results Independent associations with dysphagia were found with the C3 PVST thickness (day 30: ≥8.3 mm, day 60: ≥9.4 mm) and tracheostomy. Conclusion PVST thickness or injury seems to be an independent risk factor for dysphagia. By measuring PVST, it is possible to estimate the severity of dysphagia even in acute conditions.

Abstract
OBJECTIVE To examine whether commonly used comorbidity indexes (Deyo-Charlson comorbidity index, Elixhauser comorbidity index, the Centers for Medicare and Medicaid Services [CMS] comorbidity tiers) capture comorbidities in the acute traumatic and nontraumatic SCI inpatient rehabilitation population. DESIGN Retrospective cross-sectional study. PARTICIPANTS Data were obtained from the Uniform Data System for Medical Rehabilitation from October 1, 2015 to December 31, 2017 for adults with spinal cord injury (SCI) (Medicare-established Impairment Group Codes 04.110-04.230, 14.1, 14.3). This study included SCI discharges (N=66,235) from 833 inpatient rehabilitation facilities. MAIN OUTCOME MEASURES International Classification of Diseases-10th Revision-Clinical Modifications (ICD-10-CM) codes were used to assess 3 comorbidity indexes (Deyo-Charlson comorbidity index, Elixhauser comorbidity index, CMS comorbidity tiers). The comorbidity codes that occurred with >1% frequency were reported. The percentages of discharges for which no comorbidities were captured by each comorbidity index were calculated. RESULTS Of the total study population, 39,285 (59.3%) were men and 11,476 (17.3%) were tetraplegic. The mean number of comorbidities was 14.7. There were 13,939 distinct ICD-10-CM comorbidity codes. There were 237 comorbidities that occurred with >1% frequency. The Deyo-Charlson comorbidity index, Elixhauser comorbidity index, and the CMS tiers did not capture comorbidities of 58.4% (95% confidence interval, 58.08%-58.84%), 29.4% (29.07%-29.76%), and 66.1% (65.73%-66.46%) of the discharges in our study, respectively, and 28.8% (28.42%-29.11%) of the discharges did not have any comorbidities captured by any of the comorbidity indexes. CONCLUSION Commonly used comorbidity indexes do not reflect the extent of comorbid disease in the SCI rehabilitation population. This work suggests that alternative measures may be needed to capture the complexity of this population.

Abstract
Objectives: To identify and describe the types and time course of dysphagia following cervical spinal cord injury (SCI). Methods: This was a prospective cohort study conducted in an SCI inpatient rehabilitation unit. Seventy-six individuals with SCI were enrolled. Inclusion criteria were age 18 years or older, admitted into SCI inpatient rehabilitation unit, and medically stable for participation in bedside swallow evaluation (BSE) and videofluoroscopic swallow study (VFSS). All participants first underwent a BSE, of whom 33 completed a VFSS. A follow-up BSE was conducted on individuals who tested positive on the initial BSE and continued to show signs of dysphagia. Diagnosis and type of dysphagia as well risk factors were collected. Results: Twenty-three out of 76 individuals with cervical SCI were diagnosed with dysphagia using the BSE. All participants with positive BSE and VFSS had pharyngeal dysfunction. For participants with a positive initial BSE and persisting dysphagia (n = 14), a follow-up BSE demonstrated resolution within 34 days. Risk factors associated with dysphagia were older age, nasogastric tube, invasive mechanical ventilation, tracheostomy, and pneumonia. Posterior spinal surgery was associated with a decreased risk of dysphagia. Conclusion: Dysphagia was present in 30% of individuals based on the initial BSE. All individuals with dysphagia demonstrated pharyngeal phase dysfunction on the VFSS. No participants experiencing dysphagia were missed on the BSE as confirmed by VFSS. In the subset of individuals who received a follow-up BSE, the time course of resolution of dysphagia was at most 34 days from initial BSE.

Abstract
Spinal cord injury (SCI) is a devastating and complicated condition with no cure available. The initial mechanical trauma is followed by a secondary injury characterized by inflammatory cell infiltration and inhibitory glial scar formation. Due to the limitations posed by the blood-spinal cord barrier, systemic delivery of therapeutics is challenging. Recent development of various nanoscale strategies provides exciting and promising new means of treating SCI by crossing the blood-spinal cord barrier and delivering therapeutics. As such, we discuss different nanomaterial fabrication methods and provide an overview of recent studies where nanomaterials were developed to modulate inflammatory signals, target inhibitory factors in the lesion, and promote axonal regeneration after SCI. We also review emerging areas of research such as optogenetics, immunotherapy and CRISPR-mediated genome editing where nanomaterials can provide synergistic effects in developing novel SCI therapy regimens, as well as current efforts and barriers to clinical translation of nanomaterials.

Abstract
INTRODUCTION Surviving a traumatic cervical Spinal Cord Injury (SCI) has an immense effect on an individual's physical function and independence. It also predisposes them to financial, social, psychological and several medical complications throughout their life. In high-income countries, improved multidisciplinary care has led to better long term outcomes, however in low-income countries, the burden of the condition and its associated mortality remain high. The aim of this study was to illustrate the sociodemographic and clinical characteristics of cervical level Traumatic Spinal Cord Injuries (TSCIs) at Kilimanjaro Christian Medical Centre (KCMC) in northern Tanzania. METHODS This was a retrospective hospital-based study of 105 cervical TSCI cases admitted to KCMC from January 2012 to December 2016. RESULTS We included 105 patients in the study cohort, with a male preponderance of 86.7%, giving a male-to-female ratio of 6.5:1. The mean age at injury was 44.1 years. Overall, 65.7% were farmers and 69 patients were from within the Kilimanjaro region. Road Traffic Crashes (RTCs) accounted for 47.6% of the injuries, 17.9% had associated injuries, 38.1% sustained complete TSCIs and 45.7% developed secondary complications during the ward stay. The mortality rate before discharge from hospital care was 35.2%. CONCLUSION The majority of patients were males from a low socioeconomic background and the most common cause of injury was RTCs. The secondary complication rates and mortality rates before discharge from hospital care are high.

Abstract
Study design A multi-centre online survey to staff working in specialised and non-specialised acute units. Objectives To identify clinical decisions and practices made for acute cervical spinal cord injury (CSCI) patients with respiratory impairments and oropharyngeal dysphagia. Settings All hospital intensive care units in the UK that admit acute cervical spinal cord injury patients. Methods Online distribution of a 35-question multiple-choice survey on the clinical management of ventilation, swallowing, nutrition, oral hygiene and communication for CSCI patients, to multi-disciplinary staff based in specialised and non-specialised intensive care units across UK. Results Responses were received from 219 staff members based in 92 hospitals. Of the 77 units that admitted CSCI patients, 152 participants worked in non-specialised and 30 in specialised units. Non-specialised unit staff showed variations in clinical decisions for respiratory management compared to specialised units with limited use of vital capacity measures and graduated weaning programme, reliance on coughing to indicate aspiration, inconsistent manipulation of tracheostomy cuffs for speech and swallowing and limited use of instrumental assessments of swallowing. Those in specialised units employed a multi-discplinary approach to clinical management of nutritional needs. Conclusions Variation in the clinical management of respiratory impairments and oropharyngeal dysphagia between specialised and non-specialised units have implications for patient outcomes and increase the risk of respiratory complications that impact mortality. The future development of clinical guidance is required to ensure best practice and consistent care across all units.

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.

Abstract
BACKGROUND Healthcare systems internationally are under an ever-increasing demand for services that must be delivered in an efficient, effective and affordable manner. Several patient-related and organisational factors influence health-care expenditure and utilisation, including oropharyngeal dysphagia. Here, we present a systematic review of the literature and meta-analyses investigating how oropharyngeal dysphagia influences healthcare utilisation through length of stay (LOS) and cost. METHODS Using a standardised approach, eight databases were systematically searched for relevant articles reporting on oropharyngeal dysphagia attributable inpatient LOS and healthcare costs through June 2016. Study methodologies were critically appraised and where appropriate, extracted LOS data were analysed in an overall summary statistic. RESULTS Eleven studies reported on cost data, and 23 studies were included reporting on LOS data. Descriptively, the presence of dysphagia added 40.36% to health care costs across studies. Meta-analysis of all-cause admission data from 13 cohort studies revealed an increased LOS of 2.99 days (95% CI, 2.7, 3.3). A subgroup analysis revealed that admission for stroke resulted in higher and more variable LOS of 4.73 days (95% CI, 2.7, 7.2). Presence of dysphagia across all causes was also statistically significantly different regardless of geographical location: Europe (8.42 days; 95% CI, 4.3; 12.5), North America (3.91 days; 95% CI, 3.3, 4.5). No studies included in meta-analysis were conducted in Asia. CONCLUSIONS This systematic review demonstrated that the presence of oropharyngeal dysphagia significantly increases healthcare utilisation and cost, highlighting the need to recognise oropharyngeal dysphagia as an important contributor to pressure on healthcare systems.

Risk factors for dysphagia after a spinal cord injury: a systematic review and meta-analysis. Spinal Cord 2018; 56:1116-1123. [PMID: 29955090 DOI: 10.1038/s41393-018-0170-3] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Revised: 06/07/2018] [Accepted: 06/07/2018] [Indexed: 12/23/2022]
Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To determine the risk factors predictive of dysphagia after a spinal cord injury (SCI). SETTING None. METHODS A comprehensive literature search was performed in five scientific databases for English articles that identified risk factors for dysphagia after a SCI in adult (≥19 years) individuals. Data extracted included: author name, year and country of publication, participant demographics, sample size, study design, method of dysphagia diagnosis, and risk factor percentages. Methodological quality of studies was assessed using the Newcastle-Ottawa Scale. For identified risk factors, risk percentages were transformed into risk ratios (RR) with 95% confidence intervals. Quantitative synthesis was performed for risk factors reported in two or more studies using restricted maximum-likelihood estimator random effects models. RESULTS Eleven studies met inclusion criteria of which ten studies were of moderate quality (n = 10). Significant risk factors included: age, injury severity, level of injury, presence of tracheostomy, coughing, voice quality, bronchoscopy need, pneumonia, mechanical ventilation, nasogastric tubes, comorbid injury, and a cervical surgery. Results of the quantitative synthesis indicated that the presence of a tracheostomy posed a threefold greater risk of the development of dysphagia (RR: 3.67); while, cervical surgery posed a 1.3 times greater risk of the development of dysphagia (RR: 1.30). CONCLUSIONS Knowledge of these risk factors can be a resource for clinicians in the early diagnosis and appropriate medical management of dysphagia post SCI.

Abstract
Respiratory complications are potential causes of death in patients with spinal cord injury (SCI). Nocturnal swallowing could be related to transient arousals and could lead to fragmented sleep in SCI patients. However, the impact of nocturnal swallowing on breathing and sleep physiology in SCI is unknown. The objectives of this study were 1) to determine whether nocturnal swallowing is more common in SCI than in able-bodied (AB) subjects, 2) to determine the role of nocturnal swallowing on arousal threshold (ArTh) in SCI individuals with sleep-disordered breathing (SDB), and 3) to determine the effect of continuous positive airway pressure (CPAP) treatment on nocturnal swallowing. A total of 16 SCI and 13 AB subjects with SDB completed in-laboratory polysomnography with a pharyngeal catheter. A swallowing event (SW) was defined as a positive spike in pharyngeal pressure and was used to calculate the swallow index (SI) defined as a number of SW/total sleep time. Each SW was assessed for a relationship to the sleep stages and respiratory cycle phases, and associated arousals and ArTh were calculated. SI was higher in the SCI group compared with AB subjects during wake and different sleep stages ( P < 0.05). SWs were found to be significantly higher in the late expiratory phase in the group with SCI compared with the other respiratory phases and were eliminated by CPAP ( P < 0.05). ArTh for the subjects with SCI was significantly lower ( P < 0.05) compared with the AB subjects. Nocturnal swallowing is more common in SCI than in AB individuals who have SDB, particularly during the expiratory phase. The ArTh is significantly lower in SCI (indicating increased arousal propensity), which may contribute to the mechanism of sleep disturbances in SCI. NEW & NOTEWORTHY Nocturnal swallowing is common in patients with chronic spinal cord injury (SCI) and is associated with frequent arousals from sleep. The lower arousal threshold during sleep in SCI may contribute to the mechanism of sleep disturbances that are commonly found in cervical and high thoracic SCI. Continuous positive airway pressure may play a therapeutic role in alleviating nocturnal swallowing, which may contribute to reduced risk of aspiration.

Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVES This prospective cohort study aims to evaluate the recovery of penetration/aspiration and functional feeding outcome in patients with acute TCSCI. SETTING Tampere University Hospital, Tampere, Finland METHODS: Forty-six patients with TCSCI were enrolled. All the patients received speech therapeutic interventions based on their clinical needs and were examined with a videofluoroscopic swallowing study (VFSS) at enrollment. The incidence of VFSS-verified laryngeal penetration/aspiration according to Rosenbek's Penetration-Aspiration Scale (PAS) served as the primary outcome. The secondary outcome was the level of functional oral intake (as per the Functional Oral Intake Scale; FOIS). Based on the PAS results, the patients were divided into two groups: (i) penetrator/aspirators (PAS score ≥3) and (ii) non-penetrator/aspirators (PAS score ≤2). Follow-up VFS studies were primarily conducted on the patients with penetration/aspiration in prior VFS studies. The follow-up VFS studies were scheduled on the basis of clinical demand. RESULTS Of the 46 patients, 48% had penetration/aspiration in the first VFSS. The second VFSS was conducted on 20 patients, of whom 6 patients (30%) had penetration/aspiration. The third VFSS was conducted on 9 patients. Of these, only two (22%) patients were still penetrator/aspirators. The majority (n = 37, 88%) of the patients presented a total oral intake without restrictions at the time of the final follow-up. Only one patient (2%) was still tube-dependent with consistent oral intake. CONCLUSION Swallowing physiology in patients with TCSCI improved during the first months after injury, and the number of penetrator/aspirators decreased progressively.

Abstract
BACKGROUND CONTEXT Laryngeal penetration-aspiration, the entry of material into the airways, is considered the most severe subtype of dysphagia and is common among patients with acute cervical spinal cord injury (SCI). PURPOSE The aim of this study was to investigate risk factors for penetration-aspiration in patients with acute traumatic cervical spinal cord injury (TCSCI). STUDY DESIGN This is a prospective cohort study. PATIENT SAMPLE Thirty-seven patients with TCSCI were included in the study. OUTCOME MEASURES The highest Rosenbek penetration-aspiration scale (PAS; range 1-8) score of each patient was the primary outcome measure. The risk factors consisted of patient characteristics, demographics, and clinical signs observed during a clinical swallowing trial. MATERIALS AND METHODS A clinical swallowing trial and videofluoroscopic swallowing study (VFSS) was performed on all patients within 28 days post injury. For group comparisons, the patients were divided into two groups: (1) penetrator-aspirators (PAS score ≥3) and (2) non-penetrator-aspirators (PAS score ≤2). RESULTS Of the 37 patients, 83.8% were male. The mean age at the time of the injury was 61.2 years. Most patients had an incomplete TCSCI (78.4%) caused by a fall (75.7%). In the VFSS, 51.4% of the patients were penetrator-aspirators, and 71.4% had silent aspiration. The risk factors for predicting penetration-aspiration were (1) necessity of bronchoscopies, (2) lower level of anterior cervical operation, (3) coughing, throat clearing, choking related to swallowing, and (4) changes in voice quality related to swallowing. Binary logistic regression identified coughing, throat clearing, choking, and changes in voice quality related to swallowing as independent risk factors for penetration-aspiration. CONCLUSIONS The necessity of bronchoscopies, postinjury lower cervical spine anterior surgery, coughing, throat clearing, choking, and changes in voice quality related to swallowing was a markedrisk factor for aspiration and penetration following a cervical SCI. These factors and signs should be used to suspect injury-related pharyngeal dysfunction and to initiate preventive measures to avoid complications. The clinical swallowing evaluation is a relevant adjunct in the management of these patients and can improve the detection of penetration and aspiration.

Abstract
PURPOSE Trauma patients admitted to the intensive care unit (ICU) are at heightened risk for oropharyngeal dysphagia and pulmonary aspiration. Timely and appropriate referrals for dysphagia may reduce mortality rates and hospital readmissions. This study sought to identify predictors of dysphagia in a large cohort of patients with multiple traumatic injuries. METHODS The Trauma Registry Database was queried for admissions at a level 1 trauma center from 2012 to 2016 who underwent instrumental swallowing evaluations. Relevant demographics, injuries, and interventions known to be associated with dysphagia were collected. The Dysphagia Outcome and Severity Scale (DOSS) was utilized to define severity of dysphagia. Regression analyses were performed to identify predictors of dysphagia. RESULTS Two hundred and sixty two patients met criteria. Multivariate analyses found injury severity (p<0.01), tracheostomy (p<0.05), TBI (p<0.05), and cervical spinal bracing (p<0.001) to be predictors of dysphagia development. Furthermore, length of ICU stay (p<0.01) and cervical spinal bracing (p<0.01) were associated with a greater severity of dysphagia. CONCLUSIONS Oropharyngeal dysphagia is a common complication in trauma patients. Our results propose a set of predictors that should be considered when identifying critically injured patients at risk for dysphagia.

Abstract
Dysphagia is common in the elderly with significant consequences such as aspiration and malnutrition. This study seeks to investigate oropharyngeal dysphagia in elderly patients with cervical fractures and determine whether the level of cervical fracture impacts the incidence of swallowing dysfunction. Records of trauma patients ≥65 admitted with cervical fractures over a 76-month period to a level 1 trauma center were reviewed. History of dysphagia, stroke, tracheostomy or spinal cord injury were excluded criteria, leaving 161 patients for analysis. Evaluation of swallowing function was performed to identify dysphagia and variables were analyzed. A total of 161 patients met inclusion criteria and 42 (26.1%) had dysphagia. Patients with dysphagia were older (84.1 ± 8.93 vs. 79.9 ± 8.48, p = 0.006), had higher hospital length of stay (9.0 ± 4.48 vs. 4.6 ± 3.30, p = <0.0001), and were more likely to have intensive care unit days (52.4% vs. 21.8%, p = 0.0002). Non-operatively-managed patients with C1 fractures were more likely to have dysphagia than patients without C1 fractures (29.2% vs. 7.1%, p = 0.0008). After regression analysis, C1 fracture increased the likelihood of dysphagia by four times (OR = 4.0; 95% CI 1.2–13.0). Oropharyngeal dysphagia is common in elderly patients with cervical fracture. Non-operatively-managed patients with C1 fractures are at increased risk and may benefit from more vigorous surveillance.

Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVES Dysphagia is a relatively common secondary complication in patients with traumatic cervical spinal cord injuries (TCSCI). The purpose of this study was to determine the incidence of aspiration and penetration in patients with acute TCSCI. SETTING Tampere University Hospital, Tampere, Finland. METHODS A total of 46 patients with TCSCI were evaluated with a videofluoroscopic swallowing study (VFSS). Rosenbek's penetration-aspiration scale (PAS) was used to classify the degree of penetration or aspiration. The medical records of each patient were systematically reviewed. RESULTS Of the 46 patients, 85% were male. The mean age at the time of the injury was 62.1 years. Most patients had an incomplete injury (78%), and most of them due to a fall (78%). In the VFSS 19 (41%) patients penetrated and 15 (33%) aspirated. Only 12 (26%) of the patients had a PAS score of 1 indicating that swallowed material did not enter the airway. Of the patients who aspirated, 73% had silent aspiration. CONCLUSION The incidence of penetration or aspiration according to VFSS is high in this cohort of patients with TCSCI. Therefore, the swallowing function of patients with acute TCSCI should be routinely evaluated before initiating oral feeding. VFSS is highly recommended, particularly to rule out the possibility of silent aspiration and to achieve information on safe nutrition consistency.

Abstract
Objective South Australia is taking an innovative step in transforming the way its healthcare is organised and delivered to better manage current and future demands on the health system. In an environment of transforming health services, there are clear opportunities for allied health to assist in determining solutions to various healthcare challenges. A recent opinion piece proposed 10 clinician-driven strategies to assist in maximising value and sustainability of healthcare in Australia. The present study aimed to seek the perspectives of allied health clinicians, educators, researchers, policy makers and managers on these strategies and their relevance to allied health. Methods A survey of allied health practitioners was undertaken to capture their perspectives on the 10 clinician-driven strategies for maximising value and sustainability of healthcare in Australia. Survey findings were then layered with evidence from the literature. Results Highly relevant across allied health are the strategies of discontinuation of low value practices, targeting clinical interventions to those getting greatest benefit, active involvement of patients in shared decision making and self-management and advocating for integrated systems of care. Conclusions Allied health professionals have been involved in the South Australian healthcare system for a prolonged period, but their services are poorly recognised, often overlooked and not greatly supported in existing traditional practices. The results of the present study highlight ways in which healthcare services can implement strategies not only to improve the quality of patient outcomes, but also to offer innovative solutions for future, sustainable healthcare. The findings call for concerted efforts to increase the utilisation of allied health services to ensure the 'maximum value for spend' of the increasingly scarce health dollar. What is known about the topic? In medicine, clinician-driven strategies have been proposed to minimise inappropriate and costly care and maximise highly appropriate and less expensive care. These strategies were developed based on clinical experiences and with supporting evidence from scientific studies. What does this paper add? Major changes to the health system are required to slow down the growth in healthcare expenditure. This paper describes opportunities in which allied health practitioners can implement similar strategies not only to improve the quality of patient outcomes, but also to offer cost-effective solutions for a sustainable healthcare. What are the implications for practitioners? Allied health practitioners can provide solutions to healthcare challenges and assist in the transformation of healthcare in Australia. However, for this to happen, there should be concerted efforts to increase recognition of and support for the use of allied health services.

Abstract
Oropharyngeal dysphagia due to upper esophageal sphincter (UES) dysfunction is commonly encountered in the clinical setting. Selective experimental perturbation of various components of the deglutitive apparatus can provide an opportunity to improve our understanding of the swallowing physiology and pathophysiology. The aim is to characterize the pharyngeal and UES deglutitive pressure phenomena in an experimentally induced restriction of UES opening in humans. We studied 14 volunteers without any dysphagic symptoms (7 men, 66 ± 11 yr) but with various supraesophageal reflux symptoms. To induce UES restriction, we used a handmade device that with adjustment could selectively apply 0, 20, 30, or 40 mmHg pressure perpendicularly to the cricoid cartilage. Deglutitive pharyngeal and UES pressure phenomena were determined during dry and 5- and 10-ml water swallows × 3 for each of the UES perturbations. External cricoid pressure against the UES resulted in a significant increase in hypopharyngeal intrabolus pressure and UES nadir deglutitive relaxation pressure for all tested swallowed volumes (P < 0.05). Application of external cricoid pressure increased the length of the UES high pressure zone from 2.5 ± 0.2 to 3.1 ± 0.2, 3.5 ± 0.1, and 3.7 ± 0.1 cm for 20, 30, and 40 mmHg cricoid pressure, respectively (P < 0.05). External cricoid pressure had no significant effect on pharyngeal peristalsis. On the other hand, irrespective of external cricoid pressure deglutitive velopharyngeal contractile integral progressively increased with increased swallowed volumes (P < 0.05). In conclusion, acute experimental restriction of UES opening by external cricoid pressure manifests the pressure characteristics of increased resistance to UES transsphincteric flow observed clinically without affecting the pharyngeal peristaltic contractile function.

Abstract
BACKGROUND Dysphagia is a common complication after cervical spine trauma with spinal cord injury. We sought to characterize the prevalence of dysphagia within a total cervical spinal injury (CSI) population, considering the implications of spinal cord injury status and age on dysphagia development. We hypothesized that while greater rates of dysphagia would be found in geriatric and spinal cord-injured subgroups, all patients presenting with CSI would be at heightened risk for swallowing dysfunction. METHODS All trauma admissions to a level II trauma center from January 2010 to April 2014 with CSI were retrospectively reviewed. CSI was classified as any ligamentous or cervical spinous fracture with or without cord injury. Patients failing a formal swallow evaluation were considered dysphagic. The implications of dysphagia development on age and spinal cord injury status were assessed in univariate and multivariate analyses. RESULTS A total of 481 patients met study inclusion criteria, of which 123 (26%) developed dysphagia. Within the dysphagic subpopulation, 90 patients (73%) were geriatric, and 23 (19%) sustained spinal cord injury. The dysphagic subpopulation was predominantly free from spinal cord injury (81%). Multivariate analyses found age (adjusted odds ratio: 1.06; 95% confidence interval 1.04-1.07; P < 0.001) and spinal cord injury (adjusted odds ratio: 2.69; 95% confidence interval 1.30-5.56; P = 0.008) to be significant predictors of dysphagia development. CONCLUSIONS Despite spinal cord-injured patients being at increased risk for dysphagia, most of the dysphagic subpopulation was free from spinal cord injury. Geriatric and CSI patients with or without cord injury should be at heightened suspicion for dysphagia development.

Abstract
A traumatic spinal cord injury is a catastrophic event associated with physiologic disruptions to the motor, sensory, cardiovascular, and respiratory systems. Respiratory complications are a common cause of morbidity and mortality in patients with acute cervical spinal cord injury and treatments must be initiated immediately. The longer it takes for a patient to receive pulmonary treatments and mobility activities, the higher the morbidity and mortality and the longer the length of stay. Disrupted pulmonary mechanics and respiratory complications are frequent and are influenced by the level of injury.

Abstract
Safe removal of tracheal cannula is a major goal in the rehabilitation of tracheostomised patients to achieve progressive independence from mechanical support and reduce the risk of respiratory complications. A tracheal cannula may also cause significant discomfort to the patient, making verbal communication difficult. Particularly when cuffed, tracheal cannula reduces the normal movement of the larynx which can further compromise the basic swallowing defect. A close connection between respiratory, phonating, swallowing and feeding abilities to be recovered, implies a strict integration among different professionals of the rehabilitation team. An appropriate management of tracheostomy cannula is closely connected with assessment and treatment of swallowing disorders in order to limit the development of severe pulmonary and nutritional complications, but at present there are no uniform protocols in the scientific literature. Furthermore, several studies report as an essential criterion for decannulation the presence of good patient consciousness, which is often altered in patients with tracheostomy, but a general agreement is lacking.

Abstract
Introduction Traumatic spinal cord injury patients with quadriplegia associated respiratory compromise are at an immediately increased risk of developing pneumonia, but the onset of pneumonia risk and use of prevention strategies in the patient with quadriplegia due to Neuromyelitis Optica has not been described. Case report This is a case of a Neuromyelitis Optica patient with quadriplegia, dysphagia and tracheostomy that suffered recurrent fevers due to respiratory infections. The non-specific presentation and test results led to extensive testing, while the frequent recurrence resulted in the patient residing in the acute care hospital 201 days and outside of this hospital only 118 days during the period of August 2011 to June 2012. The initiation of CPAP 10 cm while sleeping overnight for 8–10 h eliminated the recurrence of respiratory infections and thereby reduced both the frequency and duration of the patient's hospital stays. Conclusions Patients with Neuromyelitis Optica differ from those with traumatic spinal cord injury as they have a chronic progressive systemic illness that causes continued deterioration of their nervous system resulting in the need for routine monitoring that ensures the timely addition of CPAP for the prevention of pneumonia and its associated medical expenses.
