Global Critical Care: Add Essentials to the Roadmap.

We thank Diaz and co-authors for their recent review of Global Critical Care [1]. We agree that many health systems under-perform as they fail to prioritize illness severity and the care of the critically unwell, focusing instead on diagnoses and medical specialities. We also agree on the great potential for epidemiological, clinical, and implementation research in global critical care to improve patient outcomes. We would like to make one correction and suggest important additions to the roadmap.
