Changing patterns in lung transplant for respiratory failure due to COVID-19 in the U.S.

Many patients with severe COVID-19 have been affected by acute respiratory distress syndrome, which has been associated with increased mortality, and up to 31% of these survivors had persistent interstitial lung abnormalities with impaired lung function and quality of life even after 6 to 24 months after initial disease. Lung transplantation quickly emerged as a viable therapy for select patients with respiratory failure due to COVID-19 by mid-2020. In this report, we identified 477 patients who underwent lung transplantation for COVID-19 in the U.S. between March 2020 and December 2022. The number of patients waitlisted and undergoing lung transplantation for COVID-19 increased steadily in the early part of the pandemic with a peak of 97 patients waitlisted between October and December 2021, before steadily decreasing since. Notably, the procedure is now increasingly being done for survivors of COVID-19 with pulmonary fibrosis, rather than for refractory ARDS patients. The 1-year post-transplant mortality was 13.7%.

One Year Into the Pandemic: Evolving COVID-19 Outcomes in Lung Transplant Recipients, a Single-center Experience.

In the early months of the coronavirus disease 2019 (COVID-19) pandemic, our center reported a mortality rate of 34% in a cohort of 32 lung transplant recipients with COVID-19 between March and May 2020. Since then, there has been evolving knowledge in prevention and treatments of COVID-19. To evaluate the impact of these changes, we describe the clinical presentation, management, and outcomes of a more recent cohort of lung transplant recipients during the second surge and provide a comparison with our first cohort. Methods: We conducted a retrospective cohort study that included all consecutive lung transplant recipients who tested positive for severe acute respiratory syndrome coronavirus 2 between November 2020 and February 28, 2021. We compared baseline demographics and major outcomes between the first- and second-surge cohorts. Results: We identified 47 lung transplant recipients (median age, 60; 51% female) who tested positive for severe acute respiratory syndrome coronavirus 2 between November 2020 and February 28, 2021. The current cohort had a higher proportion of patients with mild disease (34% versus 16%) and fewer patients with a history of obesity (4% versus 25%). Sixty-six percent (n = 31) required hospitalization and were treated with remdesivir (90%) and dexamethasone (84%). Among those hospitalized, 77% (n = 24) required supplemental oxygen, and 22% (n = 7) required invasive mechanical ventilation. The overall 90-d mortality decreased from 34% to 17% from the first cohort to the second (adjusted odds ratio, 0.26; 95% confidence interval, 0.08-0.85; P = 0.026). Conclusions: Although COVID-19-associated mortality rate in lung transplant recipients at our center has decreased over time, COVID-19 continues to be associated with significant morbidity and mortality.

Use of the Serious Illness Conversation Guide to Improve Communication with Surrogates of Critically Ill Patients. A Pilot Study.

Background: International family-centered critical care guidelines recommend formal, structured communication to ensure that clinical decision making is informed by a shared understanding of diagnosis and prognosis and patient goals and preferences. Tools to facilitate these recommendations are limited. Objective: To examine the feasibility, acceptability, and utility of a standardized serious illness conversation (SIC) to guide communication between nonpalliative care trained providers and surrogates of critically ill, mechanically ventilated patients. Methods: After providers received training, including simulation, we implemented SIC in October 2018. A total of 11 hospitalist providers were eligible to perform SICs over the study interval. Providers met in person with surrogates of adult, mechanically ventilated patients in the medical intensive care unit within 48 hours of intubation. To determine acceptability, surrogates were surveyed 2 months after SIC completion, and providers were surveyed between June and July 2018. To determine feasibility and utility, two independent investigators reviewed SIC documentation and coded responses into categories. Results: Of 72 eligible patients, advanced care planning documentation was completed in 50 patients, including 36 SICs, for an advance care planning completion rate of 69% and an SIC completion rate of 50%. The average SIC was completed in 30 minutes, 3 days after intubation. Of the 19 surrogates surveyed, 95% found the SIC to be mostly or extremely worthwhile. Nine of 11 hospitalist providers completed the follow-up survey. Each of the nine providers who completed the survey found the guide valuable to patient care and easy to administer. The conversation yielded valuable information in terms of goals, fears, and worries; sources of strength; abilities critical to the patient; and understanding how much the patient would be willing to go through for the possibility of gaining more time. Conclusion: We found that implementation of a structured communication tool in the intensive care unit was feasible and acceptable to surrogates and providers; yet, fidelity to the timing and completion was modest. The tool appeared to yield valuable information for understanding the goals, fears, and care preferences of mechanically ventilated patients. Steps to increase fidelity, in accordance with family-centered care guidelines, are warranted.

Utilization of Continuous Cardiac Monitoring on Hospitalist-led Teaching Teams.

Guidelines for continuous cardiac monitoring (CCM) have focused almost exclusively on cardiac diagnoses, thus limiting their application to a general medical population. In this study, a retrospective chart review was performed to identify the reasons that general medical patients, cared for on hospitalist-led inpatient teaching teams between April 2017 and February 2018, were initiated and maintained on CCM, and to determine the incidence of clinically significant arrhythmias in this patient population. The three most common reasons for telemetry initiation were sepsis (24%), arrhythmias (12%), and hypoxia (10%). Most patients remained on telemetry for more than 48 hours (62%) and a significant number of patients were on telemetry until they were discharged from the hospital (39%). Of the cumulative total of more than 20,573 hours of CCM provided to this patient population, 37% of patients demonstrated only normal sinus rhythm and 3% had a clinically significant arrhythmia that affected management.
