RESUMO
OBJECTIVE: Describe the tracheostomy and ventilation management of patients admitted due to COVID-19 as facilitated by speech language pathologists (SLPs) and otolaryngologists within the long-term acute care hospital (LTACH) setting. STUDY DESIGN: Retrospective cohort study. SETTING: Long-term acute care hospital. SUBJECTS AND METHODS: A retrospective chart review was conducted on all patients admitted to RML Specialty Hospital for respiratory failure secondary to COVID-19 from April 1, 2020 to November 30, 2021. Demographic information, laryngeal findings, and tracheostomy management was reviewed. Descriptive statistics and chi-square analysis were performed. RESULTS: Amongst the 213 subjects, 80.0 % arrived on mechanical ventilation. 23.0 % required otolaryngology consultation during LTACH stay due to poor Passy Muir Valve (PMV) or tracheostomy capping tolerance. 35 (71.4 %) of those consulted had abnormal laryngeal findings on exam with subglottic/tracheal stenosis and laryngeal edema being most common at 38.8 % and 20.4 %, respectively. 28.6 % of those with laryngeal findings were decannulated by discharge. Mechanical ventilator weaning and decannulation success were 86.6 % and 62.5 %, respectively. No association (p > 0.05) between number of intubations and abnormal laryngeal findings were found. No association (p > 0.05) between number of intubations or prone-positioning and decannulation success at discharge were found. CONCLUSION: LTACHs can serve a specific role in upper airway rehabilitation and tracheostomy care in the post COVID-19 period. SLPs and otolaryngologists should be involved in the care of these patients to help facilitate decannulation and return to normal laryngeal function.

PURPOSE: Long term acute care hospitals (LTACHs) saw a significant increase in COVID-19 patients with prolonged acute illness recovery. Speech language pathologists (SLP) in LTACHs were integral in assessing swallowing and providing rehabilitation for dysphagia, however, there is limited research on LTACHs and dysphagia. Our aim was to describe this unique dysphagia management experience to improve future patient care. METHODS: Retrospective chart reviews were conducted for patients admitted to RML Specialty Hospital for respiratory failure secondary to COVID-19 from April 1, 2020 to October 31, 2021. Demographic information, videofluoroscopic swallow study (VFSS) reports with Penetration and Aspiration Scale (PAS) scores and SLP notes were reviewed. Descriptive statistics and chi-square analysis were performed. RESULTS: A total of 213 patients met inclusion criteria. Most patients presented with tracheostomy (93.9%) and were NPO (92.5%) on admission. A strong correlation (p = 0.029) was noted between dependence on mechanical ventilation and significant airway invasion, as indicated by PAS score of 7 or 8 on VFSS. There was a strong association (p = 0.001) between patients who had tracheostomy placed within 33 days of VFSS and recommendation for thin liquids. Upon discharge, the majority of patients (83.57%) transitioned successfully to oral diets, however, a strong association (p = 0.009) between higher age (≥ 62) and NPO at discharge was demonstrated. CONCLUSION: Patients admitted post COVID-19 to LTACH, especially those requiring tracheostomy, demonstrated various degrees of dysphagia and benefited from SLP intervention and instrumental swallow assessments. Most patients admitted to LTACH for COVID-19 were successfully rehabilitated for dysphagia.

Rationale: Patients managed at a long-term acute-care hospital (LTACH) for weaning from prolonged mechanical ventilation are at risk for profound muscle weakness and disability. Objectives: To investigate effects of prolonged ventilation on survival, muscle function, and its impact on quality of life at 6 and 12 months after LTACH discharge. Methods: This was a prospective, longitudinal study conducted in 315 patients being weaned from prolonged ventilation at an LTACH. Measurements and Main Results: At discharge, 53.7% of patients were detached from the ventilator and 1-year survival was 66.9%. On enrollment, maximum inspiratory pressure (Pimax) was 41.3 (95% confidence interval, 39.4-43.2) cm H2O (53.1% predicted), whereas handgrip strength was 16.4 (95% confidence interval, 14.4-18.7) kPa (21.5% predicted). At discharge, Pimax did not change, whereas handgrip strength increased by 34.8% (P < 0.001). Between discharge and 6 months, handgrip strength increased 6.2 times more than did Pimax. Between discharge and 6 months, Katz activities-of-daily-living summary score improved by 64.4%; improvement in Katz summary score was related to improvement in handgrip strength (r = -0.51; P < 0.001). By 12 months, physical summary score and mental summary score of 36-item Short-Form Survey returned to preillness values. When asked, 84.7% of survivors indicated willingness to undergo mechanical ventilation again. Conclusions: Among patients receiving prolonged mechanical ventilation at an LTACH, 53.7% were detached from the ventilator at discharge and 1-year survival was 66.9%. Respiratory strength was well maintained, whereas peripheral strength was severely impaired throughout hospitalization. Six months after discharge, improvement in muscle function enabled patients to perform daily activities, and 84.7% indicated willingness to undergo mechanical ventilation again.

IMPORTANCE: Patients requiring prolonged mechanical ventilation (>21 days) are commonly weaned at long-term acute care hospitals (LTACHs). The most effective method of weaning such patients has not been investigated. OBJECTIVE: To compare weaning duration with pressure support vs unassisted breathing through a tracheostomy collar in patients transferred to an LTACH for weaning from prolonged ventilation. DESIGN, SETTING, AND PARTICIPANTS: Between 2000 and 2010, a randomized study was conducted in tracheotomized patients transferred to a single LTACH for weaning from prolonged ventilation. Of 500 patients who underwent a 5-day screening procedure, 316 did not tolerate the procedure and were randomly assigned to receive weaning with pressure support (n = 155) or a tracheostomy collar (n = 161). Survival at 6- and 12-month time points was also determined. MAIN OUTCOME MEASURE: Primary outcome was weaning duration. Secondary outcome was survival at 6 and 12 months after enrollment. RESULTS: Of 316 patients, 4 were withdrawn and not included in analysis. Of 152 patients in the pressure-support group, 68 (44.7%) were weaned; 22 (14.5%) died. Of 160 patients in the tracheostomy collar group, 85 (53.1%) were weaned; 16 (10.0%) died. Median weaning time was shorter with tracheostomy collar use (15 days; interquartile range [IQR], 8-25) than with pressure support (19 days; IQR, 12-31), P = .004. The hazard ratio (HR) for successful weaning rate was higher with tracheostomy collar use than with pressure support (HR, 1.43; 95% CI, 1.03-1.98; P = .033) after adjusting for baseline clinical covariates. Use of the tracheostomy collar achieved faster weaning than did pressure support among patients who did not tolerate the screening procedure between 12 and 120 hours (HR, 3.33; 95% CI, 1.44-7.70; P = .005), whereas weaning time was equivalent with the 2 methods in patients who did not tolerate the screening procedure within 0 to 12 hours. Mortality was equivalent in the pressure-support and tracheostomy collar groups at 6 months (55.92% vs 51.25%; 4.67% difference, 95% CI, -6.4% to 15.7%) and at 12 months (66.45% vs 60.00%; 6.45% difference, 95% CI, -4.2% to 17.1%). CONCLUSION AND RELEVANCE: Among patients requiring prolonged mechanical ventilation and treated at a single long-term care facility, unassisted breathing through a tracheostomy, compared with pressure support, resulted in shorter median weaning time, although weaning mode had no effect on survival at 6 and 12 months. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01541462.

Aged mice are less likely to survive following traumatic injury and are more immunosuppressed than young mice who sustain comparable injuries. Immunosuppression in severely injured patients is associated with a TH1-TH2 shift. Young mice had robust delayed-type hypersensitivity (DTH) responses after receiving scald or sham injury, whereas the response was diminished in aged sham-injured mice (P < 0.05), and completely absent in aged burn-injured mice (P < 0.01). Production of interferon-gamma (IFN-gamma) did not differ between splenocytes from sham-injured young and aged mice. Splenocytes from burn-injured young and aged mice yielded similar (63-68%) decreases in IFN-gamma, relative to sham-injured mice (P < 0.05). In the absence of injury, cells from aged mice produced 2-fold more interleukin-4 (IL-4) than cells from young (P < 0.01). Interestingly, after burn, less IL-4 was produced by cell from young and aged mice, when compared to age-matched sham-injured animals (P < 0.05). Further studies revealed that estrogen replacement in aged mice restored the post-injury DTH responses (P < 0.05). Interestingly, this restoration paralleled a recovery in IFN-gamma production by splenocytes, but not IL-4 production. Additional studies will be required to determine if age-specific therapies are needed for the treatment of all trauma patients.

PURPOSE: Weaning from prolonged mechanical ventilation may be associated with mental discomfort. It is not known whether such discomfort is linked with the development of post-traumatic stress disorder (PTSD). Accordingly, we investigated whether PTSD occurs in patients after weaning from prolonged ventilation. We also determined whether administering a questionnaire would identify patients at risk for developing PTSD. METHODS: A prospective longitudinal study of patients transferred to a long-term acute-care hospital for weaning from prolonged ventilation was undertaken: 72 patients were studied 1 week after weaning, and 41 patients were studied again 3 months later. An experienced psychologist conducted a structured clinical interview 3 months after weaning to establish a diagnosis of PTSD. To assess for the presence of PTSD-related symptoms, the post-traumatic stress syndrome (PTSS-10) questionnaire was administered 1 week after weaning and 3 months later. RESULTS: The psychologist diagnosed PTSD in 12% of patients 3 months after ventilator weaning. Patients who developed PTSD were more likely to have a previous history of psychiatric disorders (P < 0.02). A PTSS-10 score >20 one week after weaning reliably identified patients who were diagnosed with PTSD 3 months later: sensitivity 1.0; specificity 0.76; area under the receiver-operating characteristic curve 0.91. CONCLUSION: PTSD was diagnosed in 12% of patients who were weaned from prolonged ventilation. A PTSS-10 score >20 one week after weaning identified patients diagnosed with PTSD 3 months later. This finding suggests that a simple questionnaire administered before hospital discharge can identify patients at risk for developing PTSD.

PURPOSE: Patients who require mechanical ventilation are at risk of emotional stress because of total dependence on a machine for breathing. The stress may negatively impact ventilator weaning and survival. The purpose of this study was to determine whether depressive disorders in patients being weaned from prolonged mechanical ventilation are linked to weaning failure and decreased survival. METHODS: A prospective study of 478 consecutive patients transferred to a long-term acute care hospital for weaning from prolonged ventilation was undertaken. A clinical psychologist conducted a psychiatric interview to assess for the presence of depressive disorders. RESULTS: Of the 478 patients, 142 had persistent coma or delirium and were unable to be evaluated for depressive disorders. Of the remaining 336 patients, 142 (42%) were diagnosed with depressive disorders. In multivariate analysis, co-morbidity score [odds ratio (OR), 1.23; P = 0.007], functional dependence before the acute illness (OR, 1.70, P = 0.03) and history of psychiatric disorders (OR, 3.04, P = 0.0001) were independent predictors of depressive disorders. The rate of weaning failure was higher in patients with depressive disorders than in those without such disorders (61 vs. 33%, P = 0.0001), as was mortality (24 vs. 10%, P = 0.0008). The presence of depressive disorders was independently associated with mortality (OR, 4.3; P = 0.0002); age (OR, 1.06; P = 0.001) and co-morbidity score (OR, 1.24; P = 0.02) also predicted mortality. CONCLUSION: Depressive disorders were diagnosed in 42% of patients who were being weaned from prolonged ventilation. Patients with depressive disorders were more likely to experience weaning failure and death.

The elderly are less able to survive burn injury than young healthy individuals. Regardless of age, burn victims often succumb to secondary infections rather than the primary injury. Since immune responses diminish with age, it is likely that aged individuals are predisposed to a poor outcome by virtue of their weak immune system. Elevated production of macrophage-derived mediators, including interleukin-6 (IL-6), may lead to post-injury immunosuppression in young adults. Healthy aged individuals produce high circulating levels of these mediators; therefore, the combination of the age and burn trauma could further suppress immune responses and contribute to the rapid demise of aged burn patients. Herein, the effects of age and burn trauma using a murine scald injury model were examined. After injury, aged mice are less likely to survive, are unable to mount immune responses, and produce more IL-6 when compared to young adult mice given the same size injuries. Enhancing our understanding of the mechanisms responsible for regulating cell-mediated immune responses after injury could lead to the development of therapies designed to treat aged burn patients.
RESUMO
BACKGROUND: More than 100,000 people each year are admitted to U.S. hospitals for severe burn injury. Strikingly, ethanol use prior to injury is apparent in nearly 50% of burn patients, rendering them six times more likely to die from infection than patients not exposed to ethanol. We previously reported that the kinetics and magnitude of neutrophil chemokine production and subsequent accumulation of neutrophils in the lung was dramatically altered when ethanol exposure preceded injury. Here, we tested whether burn injury and ethanol exposure combined, altered susceptibility to infection, neutrophil chemoattractant production, and neutrophil accumulation at the site of the burn wound. METHODS: Male B(6)D(2)F1 mice were administered a dose of ethanol designed to achieve 90-100 mg/dl circulating levels and 30 min later subjected to a 15% total body surface area dorsal scald injury. Susceptibility to topically applied Pseudomonas aeruginosa was examined. At various times after injury, burn wound and normal tissues were collected for assessments of neutrophil counts, myeloperoxidase quantitation, and neutrophil chemoattractant (KC and MIP-2) production. RESULTS: Ethanol exposure prior to burn injury enhanced susceptibility to infection after burn and was associated with significantly elevated production of KC, but not MIP-2, at the wound site. Despite the enhanced elevation of KC, neutrophil accumulation in the wounds of ethanol exposed, burn injured mice did not differ from those that received burn injury alone. TNFalpha (a potent activator of neutrophils), however, was found to be significantly elevated in the wounds of mice that received only burn injury, but not in those that received injury in combination with prior ethanol exposure. CONCLUSION: In the presence of ethanol, neutrophils are adequately recruited to the site of burn injury, but their host defense functions are impaired, perhaps due to the lack of proinflammatory cytokines such as TNFalpha.
