Perceived Hospital Stress, Severe Acute Respiratory Syndrome Coronavirus 2 Activity, and Care Process Temporal Variance During the COVID-19 Pandemic.

OBJECTIVES: The COVID-19 pandemic threatened standard hospital operations. We sought to understand how this stress was perceived and manifested within individual hospitals and in relation to local viral activity. DESIGN: Prospective weekly hospital stress survey, November 2020-June 2022. SETTING: Society of Critical Care Medicine's Discovery Severe Acute Respiratory Infection-Preparedness multicenter cohort study. SUBJECTS: Thirteen hospitals across seven U.S. health systems. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We analyzed 839 hospital-weeks of data over 85 pandemic weeks and five viral surges. Perceived overall hospital, ICU, and emergency department (ED) stress due to severe acute respiratory infection patients during the pandemic were reported by a mean of 43% ( sd , 36%), 32% (30%), and 14% (22%) of hospitals per week, respectively, and perceived care deviations in a mean of 36% (33%). Overall hospital stress was highly correlated with ICU stress (ρ = 0.82; p < 0.0001) but only moderately correlated with ED stress (ρ = 0.52; p < 0.0001). A county increase in 10 severe acute respiratory syndrome coronavirus 2 cases per 100,000 residents was associated with an increase in the odds of overall hospital, ICU, and ED stress by 9% (95% CI, 5-12%), 7% (3-10%), and 4% (2-6%), respectively. During the Delta variant surge, overall hospital stress persisted for a median of 11.5 weeks (interquartile range, 9-14 wk) after local case peak. ICU stress had a similar pattern of resolution (median 11 wk [6-14 wk] after local case peak; p = 0.59) while the resolution of ED stress (median 6 wk [5-6 wk] after local case peak; p = 0.003) was earlier. There was a similar but attenuated pattern during the Omicron BA.1 subvariant surge. CONCLUSIONS: During the COVID-19 pandemic, perceived care deviations were common and potentially avoidable patient harm was rare. Perceived hospital stress persisted for weeks after surges peaked.

Rapid Adaptation of a Surgical Research Unit to Conduct Clinical Trials During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has brought most ongoing clinical trials to a standstill, while at the same time emphasizing the need for new therapeutic treatments and strategies to mitigate the morbidity and mortality related to COVID-19. Recent publication of several observational studies has generated much discussion surrounding efficacy of drugs including hydroxychloroquine, azithromycin, and remdesivir, stressing the need for high-quality prospective, randomized control trials in patients with COVID-19. Ongoing "stay at home" orders and institutional policies mandating "work from home" for nonessential employees, which includes most research personnel, have impacted the ability to implement and conduct clinical studies. This article discusses the approach of an experienced clinical trials unit to make adjustments for ongoing studies and ensure the safety of study participants. At the same time, plans were implemented to continue collection of data to achieve endpoints, safely enroll and follow participants in studies offering potential benefit, and quickly implement new COVID-19 clinical trials. The existence of a Division of Clinical Research with regulatory, budgeting, contracting, and coordinating expertise within a department of surgery can successfully accommodate a crisis situation and rapidly adapt to new requirements for the safe, efficient, and effective conversion to a remote work force without compromising the research process.

Costimulation targeting therapies in organ transplantation.

PURPOSE OF REVIEW: Long-term side effects of posttransplant immunosuppressive agents contribute to graft loss and death. This article reviews recent publications on the potential role of costimulation targeting therapies, especially belatacept, in solid organ transplantation. RECENT FINDINGS: Belatacept, currently undergoing phase III clinical trials in renal transplantation, has shown promise as a safe and effective alternative immunosuppression regimen to calcineurin inhibitor and steroid-based therapies. Phase II trials demonstrated similar efficacy to cyclosporine, with greatly improved renal function. Although its side effects are not yet well characterized, belatacept has shown a decrease of the renal, cardiovascular, and metabolic side effects associated with calcineurin inhibitors. SUMMARY: Belatacept appears to be a safe and effective alternative to calcineurin inhibitor and steroid-based immunosuppressive strategies. Using belatacept in combination with another agent that blocks a different costimulatory pathway has proved especially effective. The results of ongoing and future phase III trials will be needed to validate current findings and determine the most effective belatacept-based regimen for patient populations.
