Failure to diagnose meningitis in children is also among the most misdiagnosed conditions by primary care doctors.

These findings are the result of a computerized literature search that compiled 34 relevant studies mostly in the US but also in Canada and Europe. The complete results of the research, led by Dr. Emma Wallace from the HRB Center for Primary Care Research of the Royal College of Surgeons in Ireland Medical School, in Dublin can be found at BMJ open.
