Prognosis of Spontaneous Pneumothorax/Pneumomediastinum in Coronavirus Disease 2019: The CoBiF Score.

ABSTRACT: Objectives: Pneumothorax and pneumomediastinum are associated with high mortality in invasively ventilated coronavirus disease 2019 (COVID-19) patients; however, the mortality rates among non-intubated patients remain unknown. We aimed to analyze the clinical features of COVID-19-associated pneumothorax/pneumomediastinum in non-intubated patients and identify risk factors for mortality. Methods: We searched PubMed Scopus and Embase from January 2020 to December 2021. We performed a pooled analysis of 151 patients with no invasive mechanical ventilation history from 17 case series and 87 case reports. Subsequently, we developed a novel scoring system to predict in-hospital mortality; the system was further validated in multinational cohorts from ten countries (n = 133). Results: Clinical scenarios included pneumothorax/pneumomediastinum at presentation (n = 68), pneumothorax/pneumomediastinum onset during hospitalization (n = 65), and pneumothorax/pneumomediastinum development after recent COVID-19 treatment (n = 18). Significant differences were not observed in clinical outcomes between patients with pneumomediastinum and pneumothorax (±pneumomediastinum). The overall mortality rate of pneumothorax/pneumomediastinum was 23.2%. Risk factor analysis revealed that comorbidities bilateral pneumothorax and fever at pneumothorax/pneumomediastinum presentation were predictors for mortality. In the new scoring system, i.e., the CoBiF system, the area under the curve which was used to assess the predictability of mortality was 0.887. External validation results were also promising (area under the curve: 0.709). Conclusions: The presence of comorbidity bilateral pneumothorax and fever on presentation are significantly associated with poor prognosis in COVID-19 patients with spontaneous pneumothorax/pneumomediastinum. The CoBiF score can predict mortality in clinical settings as well as simplify the identification and appropriate management of patients at high risk.

Project description:ImportanceManagement of severe coronavirus disease 2019 relies on advanced respiratory support modalities including invasive mechanical ventilation, continuous positive airway pressure, and noninvasive ventilation, all of which are associated with the development of subcutaneous emphysema, pneumomediastinum, and pneumothorax (herein collectively termed barotrauma).ObjectivesTo assess the occurrence rate of barotrauma in severe coronavirus disease 2019 and to explore possible associated factors.Design setting and participantsA retrospective, single-center cohort study with nested case series, conducted at University Hospital Lewisham: a 450-bed general hospital in London, United Kingdom. All patients with confirmed coronavirus disease 2019 admitted to the critical care department from March 12, to April 12, 2020, were included.Main outcomes and measuresPatients were retrospectively screened for radiological evidence of barotrauma. Admission characteristics, modalities of respiratory support, and outcomes were compared between barotrauma and nonbarotrauma groups. Respiratory parameters in the period preceding barotrauma identification were recorded.ResultsOf 83 admissions with coronavirus disease 2019, eight suffered barotrauma (occurrence rate 9.6%; 95% CI 4.3%-18.1%). Barotrauma cases had longer illness duration prior to critical care admission (10 vs 7 d; interquartile range, 8-14 and 6-10, respectively; p = 0.073) and were more often treated with continuous positive airway pressure or noninvasive ventilation as the initial modality of advanced respiratory support (87.5% vs 36.0%; p = 0.007). Patients managed with continuous positive airway pressure or noninvasive ventilation prior to the development of barotrauma had median minute ventilation of 16.2-19.9 and 21.3-22.7 L/min, respectively. Compared with the nonbarotrauma group, a higher proportion of patients with barotrauma had died (62.5% vs 43.2%), and a lower proportion of patients had been discharged (25.0% vs 53.3%) at 3-month follow-up.Conclusions and relevanceBarotrauma appears to be a common complication of severe coronavirus disease 2019. Determining whether high minute ventilation while using continuous positive airway pressure or noninvasive ventilation predisposes patients to barotrauma requires further investigation.

Project description:ObjectiveTo determine the incidence, predictors, and outcome of pneumothorax (PNX)/pneumomediastinum (PMD) in coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS).DesignObservational study.SettingTertiary-care university hospital.ParticipantsOne hundred sixteen consecutive critically ill, invasively ventilated patients with COVID-19 ARDS.InterventionsThe authors collected demographic, mechanical ventilation, imaging, laboratory, and outcome data. Primary outcome was the incidence of PNX/PMD. Multiple logistic regression analyses were performed to identify predictors of PNX/PMD.Measurements and main resultsPNX/PMD occurred in a total of 28 patients (24.1%), with 22 patients developing PNX (19.0%) and 13 developing PMD (11.2%). Mean time to development of PNX/PMD was 14 ± 11 days from intubation. The authors found no significant difference in mechanical ventilation parameters between patients who developed PNX/PMD and those who did not. Mechanical ventilation parameters were within recommended limits for protective ventilation in both groups. Ninety-five percent of patients with PNX/PMD had the Macklin effect (linear collections of air contiguous to the bronchovascular sheaths) on a baseline computed tomography scan, and tended to have a higher lung involvement at intensive care unit (ICU) admission (Radiographic Assessment of Lung Edema score 32.2 ± 13.4 v 18.7 ± 9.8 in patients without PNX/PMD, p = 0.08). Time from symptom onset to intubation and time from total bilirubin on day two after ICU admission were the only independent predictors of PNX/PMD. Mortality was 60.7% in patients who developed PNX/PMD versus 38.6% in those who did not (p = 0.04).ConclusionPNX/PMD occurs frequently in COVID-19 patients with ARDS requiring mechanical ventilation, and is associated with increased mortality. Development of PNX/PMD seems to occur despite use of protective mechanical ventilation and has a radiologic predictor sign.
