We determine the frequency of moderate or severe headache during the first 24 hours after an emergency department (ED) visit for a primary headache disorder (such as migraine or tension-type headache), determine the burden of headache during the 3 months after the ED visit, and identify predictors of poor pain and functional outcomes after ED discharge for each of these periods. ⋯ Regardless of type of primary headache disorder, ED headache patients frequently experience pain and functional impairment during the hours and months after discharge.

The epidemiology of children who present to the emergency department (ED) and leave without being seen has not been well characterized. We evaluate rates and secular trends of children who leave without being seen, identify factors associated with pediatric leave without being seen cases, and determine whether there are differences in leaving patterns between children and adults seeking emergency care. ⋯ In this national sample of patients, leave without being seen rates were similar for pediatric and adult patients and did not increase during the 6-year study period, although some variation in rates was observed for specific patient and ED characteristics. These national estimates provide an important reference for institutions to assess their ED performance.

Severe myocardial ischemia is the leading cause of arrhythmic sudden cardiac death. It is unclear, however, in which percentage of patients sudden cardiac death is triggered by ST-elevation myocardial infarction (STEMI) and whether the diagnosis of STEMI can be reliably established immediately after resuscitation from out-of-hospital sudden cardiac death. ⋯ The diagnosis of STEMI can be established in the field immediately after return of spontaneous circulation in most patients. This may enable an early decision about reperfusion therapy, ie, immediate out-of-hospital thrombolysis or targeted transfer for percutaneous coronary intervention.
