Study on Cannabinoid Hyperemesis Syndrome in Adults Visiting Emergency Departments in Maine-et-Loire

What this Trial Is About

Researchers are studying cannabinoid hyperemesis syndrome CHS, a condition causing severe abdominal pain and vomiting in people who use cannabis regularly. This syndrome is hard to diagnose and often leads to repeated emergency room visits. The study aims to estimate how common CHS is among patients visiting adult emergency departments in Maine et Loire with abdominal pain or vomiting. It is a prospective, observational study involving multiple centers. The study includes patients aged 18 to 65 who visit an emergency department for abdominal pain or vomiting for the first time during the study period. Those who report using cannabis at least once a week for more than six months complete a questionnaire either online or on paper while in the emergency room. Patients identified with CHS will be followed up by telephone three months later to track symptom changes, recurrences, treatments, and cannabis use. Participants complete questionnaires during their emergency visit, providing information about their symptoms and cannabis use. For those with CHS, follow-up calls occur three months later to assess their health and treatment outcomes. Researchers will measure the number of patients diagnosed with CHS, their age and gender distribution, clinical features, cannabis use patterns, hospital treatments, and recurrence of symptoms. The study lasts 15 months, with a 12-month inclusion period and a 3-month follow-up for CHS patients.
