Insights
Regions in Brazil with high COVID-19 mortality from comorbidities also face shortages in intensive care unit (ICU) beds and ventilators. This highlights critical disparities needing policy attention for equitable epidemic response.
Area of Science:
- Public Health
- Epidemiology
- Health Services Research
Background:
- COVID-19 necessitates increased intensive care unit (ICU) capacity globally.
- Specific comorbidities like respiratory diseases, neoplasms, hypertension, and diabetes are linked to higher COVID-19 case-fatality.
- Brazil faces challenges in matching healthcare resources to regional disease burdens.
Purpose of the Study:
- To identify Brazilian Health Regions with high mortality rates from key comorbidities.
- To pinpoint regions experiencing shortages of ICU beds and mechanical ventilators.
- To analyze the spatial overlap between high comorbidity mortality and limited critical care resources.
Main Methods:
- Cross-sectional ecological study utilizing data from DATASUS (2017-2019).
- Calculated disease-specific mortality rates and ICU bed/ventilator availability per 100,000 inhabitants.
- Employed latent profile analysis for mortality patterns and spatial scan statistics for resource analysis.
- Visualized data using Kernel maps.
Main Results:
- Four distinct latent mortality profiles were identified across Brazilian Health Regions.
- Regions exhibiting the highest mortality rates from comorbidities were found to have significant shortages of ICU beds and ventilators.
- This disparity was particularly pronounced in parts of the Northeast, Southeast, and South regions of Brazil.
Conclusions:
- A critical spatial overlap exists between high comorbidity-related mortality and insufficient ICU bed/ventilator resources in Brazil.
- Policymakers and public health planners must address these geographical disparities for effective and equitable COVID-19 management.
- Targeted resource allocation is essential to mitigate the impact of COVID-19 in vulnerable regions.
Abstract:
In response to the accelerated increase in the number of COVID-19 cases, countries must increase their supply of beds in intensive care units (ICUs). Respiratory diseases, neoplasms, cardiopathies and hypertension, and diabetes are associated with higher COVID-19 case-fatality. The study aimed to identify the regions of Brazil with higher specific mortality rates from these comorbidities and the regions with the greatest shortage of ICU beds and mechanical ventilators. A cross-sectional ecological study was performed in which the units of analysis were the country's Health Regions. Data were obtained from Brazilian Health Informatics Department - DATASUS (National Registry of Healthcare Establishments - 2019, Mortality Information Systems - 2017, and Population Projections - 2017). We calculated the disease group-specific mortality rates for hypertension, neoplasms, diabetes, cardiac diseases, respiratory diseases and the rates of total ICU beds, private ICU beds, ICU beds in the Brazilian Unified National Health System (SUS), and ventilators in the SUS, per 100,000 inhabitants. The mortality profile was determined by latent profiles analysis, and the cluster analysis of ICU beds and ventilators used the spatial scan method. Kernel maps were constructed for the data's visualization. Level of significance was set at 5%. Four latent mortality profiles were observed. The Health Regions with the highest mean mortality rates were located in regions with shortages of ICU beds and ventilators, especially in parts of the Northeast, Southeast, and South of Brazil. The spatial localization of regions with both the highest mortality and shortages of ICU beds/ventilators requires attention by policymakers and public planners to deal efficiently and fairly with the COVID-19 epidemic in Brazil.
