Association of dead space fraction to mortality in patients with COVID-19-related ARDS: A historical cohort observational study.

OBJECTIVE: To assess the correlation of dead space fraction (VD/VT) measured through time capnography, corrected minute volume (CMV) and ventilation ratio (VR) with clinical outcomes in COVID-19 patients requiring invasive mechanical ventilation. DESIGN: Observational study of a historical cohort. SETTING: University hospital in Medellin, Colombia. PARTICIPANTS: Patients aged 15 and above with a confirmed COVID-19 diagnosis admitted to the ICU and requiring mechanical ventilation. INTERVENTIONS: Measurement of VD/VT, CMV, and VR in COVID-19 patients. MAIN VARIABLES OF INTEREST: VD/VT, CMV, VR, demographic data, oxygenation indices and ventilatory parameters. RESULTS: During the study period, 1047 COVID-19 patients on mechanical ventilation were analyzed, of whom 446 (42%) died. Deceased patients exhibited a higher prevalence of advanced age and obesity, elevated Charlson index, higher APACHE II and SOFA scores, as well as an increase in VD/VT ratio (0.27 in survivors and 0.31 in deceased) and minute ventilation volume on the first day of mechanical ventilation. The multivariate analysis revealed independent associations to in-hospital mortality, higher VD/VT (HR 1.24; 95%CI 1.003-1.525; p = 0.046), age (HR 1.024; 95%CI 1.014-1.034; p < 0.001), and SOFA score at onset (HR: 1.036; 95%CI: 1.001-1.07; p = 0.017). CONCLUSIONS: VD/VT demonstrated an association with mortality in COVID-19 patients with ARDS on mechanical ventilation. These findings suggest that VD/VT measurement may serve as a severity marker for the disease.

Building an action plan to tackle palliative care inequality through multi-stakeholder platforms.

Background: To achieve universal care and overcome existing barriers, the most effective strategy is to devise an action plan that incorporates palliative care into primary health care (PHC), as recommended by the World Health Organization's (WHO) Astana Declaration. In Colombia, a country with an upper-middle-income status, about 128,000 individuals experience severe health-related suffering (SHS) that necessitates palliative care. Although the country's healthcare system has made steady strides in the integration and development of palliative care, there is still no national plan in place for palliative care. Objective: Build up Colombia's palliative care plan through stakeholder consensus. Method: Based on the participatory action research method and the multi-stakeholder platforms model, this study convened 142 stakeholders from different levels of the health system (patient representatives, journalists, health professionals, government entities, insurance companies, universities, and drug regulatory authorities). Results: The national plan aims to achieve its objectives through a series of strategic actions. These include integrating and diversifying palliative care services, improving access to opioids, increasing palliative care education, promoting community-based palliative care programs, securing funding, and implementing a regulatory framework for palliative care by public policymakers. Conclusions: The national palliative care is an alliance that aims to reduce palliative care inequity in Colombia by 2026 by empowering stakeholders nationwide to collaborate around specific goals and objectives.
