Why We Are Losing the War Against COVID-19 on the Data Front and How to Reverse the Situation.

With over 117 million COVID-19-positive cases declared and the death count approaching 3 million, we would expect that the highly digitalized health systems of high-income countries would have collected, processed, and analyzed large quantities of clinical data from patients with COVID-19. Those data should have served to answer important clinical questions such as: what are the risk factors for becoming infected? What are good clinical variables to predict prognosis? What kinds of patients are more likely to survive mechanical ventilation? Are there clinical subphenotypes of the disease? All these, and many more, are crucial questions to improve our clinical strategies against the epidemic and save as many lives as possible. One might assume that in the era of big data and machine learning, there would be an army of scientists crunching petabytes of clinical data to answer these questions. However, nothing could be further from the truth. Our health systems have proven to be completely unprepared to generate, in a timely manner, a flow of clinical data that could feed these analyses. Despite gigabytes of data being generated every day, the vast quantity is locked in secure hospital data servers and is not being made available for analysis. Routinely collected clinical data are, by and large, regarded as a tool to inform decisions about individual patients, and not as a key resource to answer clinical questions through statistical analysis. The initiatives to extract COVID-19 clinical data are often promoted by private groups of individuals and not by health systems, and are uncoordinated and inefficient. The consequence is that we have more clinical data on COVID-19 than on any other epidemic in history, but we have failed to analyze this information quickly enough to make a difference. In this viewpoint, we expose this situation and suggest concrete ideas that health systems could implement to dynamically analyze their routine clinical data, becoming learning health systems and reversing the current situation.

"Universal" doesn't just apply to health care, but to every sector's actions taken to protect the population's health.

Dr Pastor Castell-Florit's career in public health spans work at local, na-tional and international levels. In 2016, he received PAHO's Award for Health Administration in the Americas, for "outstanding leadership and valuable contributions to the management and administration of the Cuban National Health System." He serves as presi-dent of Cuba's National Council of Sci-entific Societies in Health, as director of the National School of Public Health, and is a member of the Cuban Acad-emy of Sciences. He has published numerous books and articles on so-cial determinants of health and inter-sectoral actions to address them, and holds doctorates in science and the health sciences.

Cuba's Pedro Kourí Tropical Medicine Institute:Battling COVID-19 One Study, One Test, One Patient at a Time.

This MEDICC Review roundtable brings you specialists from Havana's Pedro Kourí Tropical Medicine Institute (IPK), who are working directly with testing, research and patient care during the COVID-19 pandemic. Founded in 1937 by its namesake, the Institute has gained considerable worldwide prestige. Today, it is a PAHO-WHO Collaborating Center for the Study of Dengue and Its Vector, and for the Elimination of Tuberculosis. Its main role within Cuba's health system is as the national reference center for prevention, control, management and elimination of infectious diseases, including epidemics. Its 479 workers staff 32 departments, including laboratories, research and teach-ing facilities, a hospital and isolation center. The IPK's hospital treats later-stage AIDS patients, while the Institute is the nation-al reference center for attention to all HIV-positive patients and maintains the national HIV/AIDS registry, as well as registries for other infectious diseases. The institution was responsible for training the Cuban doctors who served in West Africa during the 2014-2016 Ebola outbreaks and for those going abroad to assist in the COVID-19 response today, and its professionals offer an internationally-recognized biennial course on dengue.
