患者は救急外来受診前に「Dr. Google」を受診する

Approximately one-third of adults search the internet for health information before visiting an emergency department (ED), with 75% encountering inaccurate content. This study examineshow such searches influence patient care. We conducted an observational study of ED visits overa 12-month period, surveying 214 of 576 patients about pre-ED internet use. Data on demographics, comorbidities, acuity, orders, prescriptions, and dispositions were extracted. Patients who searched were typically younger, healthier, and more educated. Most used a general search engine to ask symptom-related questions. Compared to non-searchers, they were less likely to receive lab tests (RR 0.78, p=0.053), imaging(RR 0.75, p=0.094), medications (RR 0.67, p=0.038), oradmission (RR 0.68, p=0.175). They were more likely to leave against medical advice (RR 1.67, p=0.067) and receive opioids (RR 1.56, p=0.151). Findings suggest inaccurate health information may contribute to mismatched expectations and alter ed care delivery.
