Observational Study
Delayed mechanical ventilation with prolonged high-flow nasal cannula exposure time as a risk factor for mortality in acute respiratory distress syndrome due to SARS-CoV-2.
In a high proportion of patients, infection by COVID-19 progresses to acute respiratory distress syndrome (ARDS), requiring invasive mechanical ventilation (IMV) and admission to an intensive care unit (ICU). Other devices, such as a high-flow nasal cannula (HFNC), have been alternatives to IMV in settings with limited resources. This study evaluates whether HFNC exposure time prior to IMV is associated with mortality. ⋯ This study also identified a significant increase in mortality after 36 h in HFNC (46.3%, p: 0.003). In patients with ARDS due to COVID-19, HFNC exposure ≥ 48 h prior to IMV is a factor associated with mortality after controlling multiple confounders. Physiological mechanisms for such an association are need to be defined.

Although the role played by general practitioners (GPs) is historically consolidated, continuous changes have been recently introduced in Europe because of the increasing multimorbidity and complexity of patients. Here we try to compare the roles played by GPs in the four major countries of Europe. In France GPs are self-employed medical doctors, and their remuneration consists of a payment scheme for the services provided. ⋯ The weekly hours worked by Spanish GPs are 38 hours, as for any other civil servant. Trying to draw positive lessons from the comparison, the Spanish facilities seem to be the most advanced examples of horizontal-integrated organizations able to fulfil the expectations of a growing population of ageing people. The range of generalist professionals could be enlarged beyond GPs, as the German example shows.
