The European Sleep Apnea Database (ESADA) (also referred to with spelling European Sleep Apnoea Database and European Sleep Apnoea Cohort) is a collaboration between European sleep centres as part of the European Cooperation in Science and Technology (COST) Action B 26. The main contractor of the project is the Sahlgrenska Academy at Gothenburg University, Institute of Medicine, Department of Internal Medicine, and the co-ordinator is Jan Hedner, MD, PhD, Professor of Sleep Medicine.

The book Clinical Genomics: Practical Applications for Adult Patient Care said ESADA was an example initiatives which afford an "excellent opportunity" for future collaborative research into genetic aspects of obstructive sleep apnea syndrome (OSAS). Both the European Respiratory Society and the European Sleep Research Society have noted the impact for research cooperative efforts of the database resource.

In 2006 the European Sleep Apnea Database (ESADA) began as an initiative between 27 European sleep study facilities to combine information and compile it into one shared resource. It was formed as part of the European Cooperation in Science and Technology (COST) Action B 26. In addition to financial help from COST, the initiative received assistance from companies Philips Respironics and ResMed. The database storing the association's resource information is located in Gothenburg, Sweden. The group's goal was twofold: to serve as a reference guide to those researching sleep disorders, and to compile information about how different caregivers treat patients suffering from sleep apnea.

5,103 patients were tracked from March 2007 to August 2009. Data collected on these patients included symptoms suffered, medication, medical history, and sleep data, all inputted into an online format for further analysis. Database researchers reported on their methodology and results in 2010 to the American Thoracic Society, on their observed findings regarding percentages of metabolic and cardiovascular changes related to patients with obstructive sleep apnea. The 2010 research resulted from collaboration between 22 study centres across 16 countries in Europe involving 27 researchers. The primary participants who presented to the American Thoracic Society included researchers from: Sahlgrenska University Hospital, Gothenburg, Sweden; Technion – Israel Institute of Technology, Haifa, Israel; National TB & Lung Diseases Research Institute, Warsaw, Poland; CNR Institute of Biomedicine and Molecular, Palermo, Italy; Instituto Auxologico Italiano, Ospedale San Luca, Milan, Italy; and St. Vincent University Hospital, Dublin, Ireland. Their analysis was published in 2010 in the American Journal of Respiratory and Critical Care Medicine.
