Disparities in sex
In many studies, the sex of the patients is included when describing the demographics. However, not many studies are designed and conducted specifically on the association between sex and outcomes in pediatric respiratory diseases. Frigyesi et al. showed a higher female mortality ratio in patients admitted with respiratory failure at the PICU but no difference was found in received care between the groups, and thus no explanation was found on the observed differences in outcomes related to the patient’s sex40. However, no distinction was made between the different etiologies of the respiratory insufficiency40. Further research is needed to identify if there truly is a sex difference related to outcomes in this patient group, and the underlying causes if so.
