| Definition of critical COVID-19 patient in Brazil | ||||
| Criteria for admission to the Intensive Care Unit (ICU) are clinical instability, i.e. the need for support for organ dysfunctions and intensive monitoring. | https://sistemas.cfm.org.br/normas/visualizar/resolucoes/BR/2016/2156 | 17 November 2016 | ||
| Priority criteria:
Priority 1 - Patients who need life support interventions, with a high probability of recovery and without any limitation of therapeutic support; Priority 2 - Patients who need intensive monitoring due to high risk of needing immediate intervention and without any limitation of therapeutic support; Priority 3 - Patients who need life support interventions with low probability of recovery or with limited therapeutic intervention; Priority 4 - Patients who need intensive monitoring due to high risk of needing immediate intervention but with limited therapeutic intervention; Priority 5 - Patients with a terminal illness or dying with no possibility of recovery. In general, these patients are not suitable for admission to the ICU (unless they are potential organ donors). However, their admission can be justified on an exceptional basis, considering the peculiarities of the case and conditioned to the criteria of the intensive care physician. |

| Critical or seriously ill patients are defined as those who present instability or risk of instability of a vital system with risk of death. These patients may suffer deterioration of one or more functions of vital organs, presenting cardiovascular, respiratory, neurological, renal, metabolic instability or pathologies that can lead to instability of these systems. | https://sistemas.cfm.org.br/normas/visualizar/resolucoes/BR/2020/2271 | 23 April 2020 | ||
| Definition of Intensive Care Unit (ICU) | ||||
| ICU is a hospital environment with an organized system to offer vital support of high complexity, with multiple modalities of monitoring and advanced organic support to maintain life during clinical conditions of extreme severity and risk of death from organ failure. This assistance is provided continuously, 24 hours a day, by a specialized multidisciplinary team. Therefore, these units aim to assist patients of greater severity, who present instability or risk of vital clinical instability and are at risk of death. Thus, they need constant vigilance and continuous treatment, according to the evolution of the disease, so that they can obtain a good result. | https://sistemas.cfm.org.br/normas/visualizar/resolucoes/BR/2020/2271 | 23 April 2020 | ||
| Definition of ICU discharge criteria | ||||
| Patient whose clinical condition is controlled and stabilized;
Patient for whom all curative/restorative therapeutic possibilities have been exhausted and who can remain in the hospital outside the ICU in a dignified manner and, if possible, together with his family. |

| Criteria for death certificate by COVID-19 in Brazil | ||||
| Any death confirmed for COVID-19 by the Death Verification Service (SVO) must be notified
immediately to the local surveillance system;
The local epidemiological surveillance system must also know when the cause of death is inconclusive or ruled out for COVID-19. |
