Stress Testing the Cardiac Catheterization Laboratory: A Novel Use of In Situ Simulation to Identify and Mitigate Latent Safety Threats During Acute Airway Management.

INTRODUCTION: Although uncommon, cardiac arrests in the cardiac catheterization laboratory (CCL) are often catastrophic and likely to increase with rising case complexity. In situ simulation (ISS) has been used to identify latent safety threats (LSTs) in inpatient units but has not yet been studied in the CCL. METHODS: Three Plan-Do-Study-Act (PDSA) cycles leveraging ISS were conducted focused on acute airway management. Data collected through debriefs focused on (1) airway management, (2) equipment availability, and (3) interdepartmental communication. The LSTs were subcategorized and plotted on the Survey Analysis for Evaluating Risk (SAFER)-Matrix. A SAFER score was calculated based on quantifying the likelihood of harm, scope, and the number of times a threat was identified during simulation. Time to definitive airway was collected as a secondary measure. Interventions were developed using cause and effect and driver diagrams between PDSA cycles. RESULTS: Eleven total simulations through 3 PDSA cycles were conducted between January and December 2021 (5 in PDSA 1, 4 in PDSA 2, and 2 in PDSA 3). One hundred one LSTs were identified with 14 total subcategories. The mean SAFER score decreased from 5.37 in PDSA 1, to 2.96 in PDSA 2, and to 1.00 in PDSA 3. Bivariate regression analysis showed a decrease in SAFER score of 2.19 for every PDSA cycle ( P = 0.011). Ordinary least squares regression had a decrease of 1.65 in airway-related threats every PDSA cycle ( P < 0.01) as well as an increase in intubation time of 35.0 seconds for every 1-unit increase in communication threat identified ( P = 0.037). CONCLUSIONS: This study successfully leveraged ISS and existing quality improvement initiatives in the CCL, resulting in a decrease in airway-related threats as measured through simulation.

Design and implementation of the hospital airway resuscitation trial.

Guidelines for the management of in-hospital cardiac arrest resuscitation are often drawn from evidence generated in out-of-hospital cardiac arrest populations and applied to the in-hospital setting. Approach to airway management during resuscitation is one example of this phenomenon, with the recommendation to place either a supraglottic airway or endotracheal tube when performing advanced airway management during in-hospital cardiac arrest based mainly in clinical trials conducted in the out-of-hospital setting. The Hospital Airway Resuscitation Trial (HART) is a pragmatic cluster-randomized superiority trial comparing a strategy of first choice supraglottic airway to a strategy of first choice endotracheal intubation during resuscitation from in-hospital cardiac arrest. The design includes a number of innovative elements such as a highly pragmatic design drawing from electronic health records and a novel primary outcome measure for cardiac arrest trials-alive-and-ventilator free days. Many of the topics explored in the design of HART have wide relevance to other trials in in-hospital cardiac arrest populations.

Outcomes After Tracheostomy for Patients With Respiratory Failure due to COVID-19.

OBJECTIVE: To evaluate the utility and safety of tracheostomy for patients with respiratory failure from COIVD-19 and describe patient clinical characteristics and process of management. METHODS: Case series of the first 24 COVID-19 patients who underwent tracheostomy at our institution, a single-center tertiary care community hospital intensive care/ventilator weaning unit. The patients all had respiratory failure from COVID-19 and required endotracheal intubation and mechanical ventilation. Outcomes reviewed include mortality, percent discharged, percent liberated from mechanical ventilation, percent decannulated, time from tracheostomy to ventilator liberation and discharge, and number of staff infected with COVID-19 during tracheostomy and management. RESULTS: Of the 24 patients who underwent tracheostomy, 21 (88%) of 24 survived. Twenty (83%) were liberated from mechanical ventilation, and 19 (79%) were discharged. Fourteen (74%) of the discharged had been decannulated. The average (± SD) time from tracheostomy to ventilator liberation was 9 ± 4.3 days and from tracheostomy to discharge 21 ± 9 days. All discharged patients had been liberated from mechanical ventilation. No health care workers became infected with COVID-19 during the procedure or subsequent patient management. CONCLUSION: Patients with respiratory failure from COVID-19 who underwent tracheostomy had a high likelihood of being liberated from mechanical ventilation and discharged. Tracheostomy and subsequent ventilator weaning management can be performed safely. Tracheostomy allowed for decompression of higher acuity medical units in a safe and effective manner.

Predictors for inpatient mortality during the first wave of the SARS-CoV-2 pandemic: A retrospective analysis.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic overwhelmed healthcare systems, highlighting the need to better understand predictors of mortality and the impact of medical interventions. METHODS: This retrospective cohort study examined data from every patient who tested positive for COVID-19 and was admitted to White Plains Hospital between March 9, 2020, and June 3, 2020. We used binomial logistic regression to analyze data for all patients, and propensity score matching for those treated with hydroxychloroquine and convalescent plasma (CP). The primary outcome of interest was inpatient mortality. RESULTS: 1,108 admitted patients with COVID-19 were available for analysis, of which 124 (11.2%) were excluded due to incomplete data. Of the 984 patients included, 225 (22.9%) died. Risk for death decreased for each day later a patient was admitted [OR 0.970, CI 0.955 to 0.985; p < 0.001]. Elevated initial C-reactive protein (CRP) value was associated with a higher risk for death at 96 hours [OR 1.007, 1.002 to 1.012; p = 0.006]. Hydroxychloroquine and CP administration were each associated with increased mortality [OR 3.4, CI 1.614 to 7.396; p = 0.002, OR 2.8560, CI 1.361 to 6.160; p = 0.006 respectively]. CONCLUSIONS: Elevated CRP carried significant odds of early death. Hydroxychloroquine and CP were each associated with higher risk for death, although CP was without titers and was administered at a median of five days from admission. Randomized or controlled studies will better describe the impact of CP. Mortality decreased as the pandemic progressed, suggesting that institutional capacity for dynamic evaluation of process and outcome measures may benefit COVID-19 survival.

The spectrum of lung disease due to chronic occult aspiration.

RATIONALE: Chronic aspiration of small volumes of oral and gastric contents can lead to lung disease. This process is less familiar than the acute aspiration syndromes, which can create confusion in terminology as well as with radiologic and pathologic definitions. OBJECTIVES: In this study we analyze a series of cases of patients with chronic occult aspiration to better define the disease process. METHODS: Twenty-five patients with chronic occult aspiration as defined pathologically on lung biopsy were studied by means of retrospective review of their case records. Clinical associations and radiologic and pathologic patterns were noted. MEASUREMENTS AND MAIN RESULTS: Among patients with chronic occult aspiration, there was a high prevalence of gastroesophageal reflux disease (96%), esophageal dysfunction (40%), oropharyngeal/laryngeal dysfunction (40%), hiatal hernias (32%), obstructive sleep apnea (32%), and obesity (52%). The radiologic presentation was typically one of multilobar centrilobular nodularity, tree-in-bud, and airway thickening, with a subset of patients having evidence of fibrosis. The disease presented pathologically with exogenous lipoid pneumonia, poorly formed granulomas, and foreign body-type multinucleated giant cells with or without foreign material. Pathologic fibrosis was also seen. CONCLUSION: In this study, chronic occult aspiration was associated with a number of comorbid conditions and a spectrum of radiologic and pathologic patterns, which in some patients included fibrosis.
