Has the management of patients with COVID-19 improved?

Text updated on 2020-09-30

Yes, between March 2020 and June 2020, the care of people with COVID-19 in hospitals has improved a lot.

In hospitals in several countries (Italy, the United Kingdom, and the United States), it has been observed that the proportion of patients hospitalized for COVID-19 who died (the in-hospital mortality rate of COVID-19 patients) decreased between March 2020 and June 2020.

There are several reasons for this good news:

In Milan, the hospital mortality rate fell from 24% in March 2020 to 2% in May 2020. And the percentage of inpatients who had to be admitted to intensive care units has also fallen.

In the United Kingdom, the hospital mortality rate fell from 6% in April 2020 to 1.5% in June 2020.

June 2020 Report of the Centre for Evidence-Based Medicine, UK.

A study of the 16,749 people with COVID-19 and admitted to hospital in the United Kingdom between February and April 2020 calculated an in-hospital mortality rate of 33%.

The analysis of 5,700 patients hospitalized for COVID-19 in the New York area between March 2020 and early April 2020 revealed a 21% hospital mortality rate.

RECOVERY clinical trial conducted in the United Kingdom in 6,324 patients with COVID-19. Clinical follow-up of 2,104 patients who were treated with corticosteroids for 10 days compared to 4,321 patients who received conventional therapeutic management. Treatment with corticosteroids reduces mortality by 35% in patients with severe COVID-19 that required invasive mechanical ventilation.

In this prospective meta-analysis of 7 randomized trials including 1,703 patients of whom 647 died, all-cause mortality at 28 days was lower in patients who received corticosteroids than in those who received usual care or a placebo.

This study in patients with COVID-19 who suffer from severe respiratory symptoms shows that ventilation through high-flow nasal cannulas can reduce the rate of intubation, which is an invasive mechanical ventilation technique for the patient.
