Shift in emergency department utilization by frequent attendees with sickle cell disease during the COVID-19 pandemic: A multicentre cohort study.

While the coronavirus disease-2019 (COVID-19) might have increased acute episodes in people living with sickle cell disease (SCD), it may also have changed their reliance on emergency department (ED) services. We assessed the impact of the COVID-19 pandemic and lockdowns on ED visits in adult SCD people followed in five French reference centres, with a special focus on 'high users' (≥10 visits in 2019). We analysed the rate of ED visits from 1 January 2015 to 31 December 2021, using a self-controlled case series. Among 1530 people (17 829 ED visits), we observed a significant reduction in ED visits during and after lockdowns, but the effect vanished over time. Compared to pre-pandemic, incidence rate ratios for ED visits were 0.59 [95% CI 0.52-0.67] for the first lockdown, 0.66 [95% CI 0.58-0.75] for the second and 0.85 [95% CI 0.73-0.99] for the third. High users (4% of people but 33.7% of visits) mainly drove the reductions after the first lockdown. COVID-19 lockdowns were associated with reduced ED visits. While most people returned to their baseline utilization by April 2021, high users had a lasting decrease in ED visits. Understanding the factors driving the drop in ED utilization among high users might inform clinical practice and health policy.

Daily multidisciplinary COVID-19 meeting: Experiences from a French university hospital.

OBJECTIVES: In March 2020, the World Health Organization declared the coronavirus disease 2019 (COVID-19) a pandemic. In absence of official recommendations, implementing daily multidisciplinary team (MDT) COVID-19 meetings was urgently needed. Our aim was to describe our initial institutional standard operating procedures for implementing these meetings, and their impact on daily practice. METHODS: All consecutive patients who were hospitalized in our institution due to COVID 19, from March 31 to April 15, 2020, were included. Criteria to be presented at MDT meetings were defined as a proven COVID-19 by PCR or strongly suspected on CT scan, requiring hospitalization and treatment not included in the standard of care. Three investigators identified the patients who met the predefined criteria and compared the treatment and outcomes of patients with predefined criteria that were presented during MDT meeting with those not presented during MDT meeting. COVID-19 MDT meeting implementation and adhesion were also assessed by a hospital medical staff survey. RESULTS: In all, 318 patients with confirmed or suspected COVID-19 were examined in our hospital. Of these, 230 (87%) were hospitalized in a COVID-19 unit, 91 (40%) of whom met predefined MDT meeting criteria. Fifty (55%) patients were presented at a MDT meeting versus 41 (45%) were not. Complementary exploration and inclusion in the CorImmuno cohort were higher in MDT meeting group (respectively 35 vs. 15%, P=0.03 and 80 versus 49%, P=0.0007). Prescription of hydrocortisone hemisuccinate was higher in group of patients not presented during MDT meeting (24 vs. 51%, P=0.007). Almost half of the patients fulfilling the inclusion criteria were not presented at MDT meeting, which can be partly explained by technical software issues. CONCLUSIONS: Multidisciplinary COVID-19 meetings helped implementing a single standard of care, avoided using treatments that were untested or currently being tested, and facilitated the inclusion of patients in prospective cohorts and therapeutic trials.
