A newly-published study conducted jointly by eighteen neuroscientists from the United States and Europe – including two researchers from The Ohio State University College of Nursing and Wexner Medical Center – and using crowdsourcing as an information-gathering method reveals the first epidemiologic data on coma in the United Kingdom and the U.S.
"In contrast to neurological conditions for which epidemiological data are available, coma results from many different brain injuries or medical diseases,” said Daniel Kondziella, a neurologist from Rigshospitalet, Copenhagen (Denmark) University Hospital and a lead author of the study. “Coma is not readily identifiable with conventional methods that utilize electronic medical records, insurance billing codes or clinical surveyance data.”
“Crowdsourcing allows us to achieve a representative sampling of participants based on official census data,” said Molly McNett, PhD, clinical professor at The Ohio State University College of Nursing and a co-author of the study. “Family members are acutely aware of the impact of coma on their loved ones and can share information with high confidence when a relative has been in a coma recently.”
The survey of nearly 2,000 people – 994 from the U.K. and 977 from the U.S. – provided data on more than 30,000 first- and second-degree family members and identified 714 plausible cases of common coma. Among the findings:
“Having this data at our disposal is critical not only in our understanding of the incidence of coma, but also in how we approach the condition at the bedside,” said Thomas Lawson, MS, lead advanced practice provider in the Neurocritical Care Unit at The Ohio State University Wexner Medical Center who is also a co-author and a PhD candidate at the College of Nursing. “The seriousness of coma requires us to gain a deeper understanding that can broaden our perspective for this and other disorders of consciousness.”
The study was sponsored by the Neurocritical Care Society’s Curing Coma Campaign which, according to its website, “is the first global public health initiative to tackle the unifying concept of coma as a treatable medical entity.”
