Long QT syndrome has significant mortality, which is reduced with appropriate management. It is known that long QT syndrome masquerades as other conditions, including seizure disorders. We aim to evaluate a series of patients with genetically confirmed long QT syndrome to establish the frequency of delayed recognition. We also examine causes and potential consequences of diagnostic delay. ⋯ Delayed diagnosis of long QT syndrome is frequent. Symptoms are often attributed to alternative diagnoses, most commonly seizure disorder. Patients labeled as epileptic experience a particularly long diagnostic delay. ECGs were frequently requested, but interpretation errors were common. Given the potentially preventable mortality of long QT syndrome, emergency physicians investigating syncope and seizure should maintain a high index of suspicion.

Since 2003, the Society of Chest Pain Centers (SCPC) has provided hospital accreditation for acute coronary syndrome care processes. Our objective is to evaluate the association between SCPC accreditation and adherence to the American College of Cardiology/American Heart Association (ACC/AHA) evidence-based guidelines for non-ST-segment elevation myocardial infarction (NSTEMI). The secondary objective is to describe the clinical outcomes and the association with accreditation. ⋯ SCPC-accredited hospitals had higher NSTEMI ACC/AHA evidence-based guideline adherence in the first 24 hours of care on 2 of the 5 measures. No difference in outcomes was observed. Further studies are needed to better understand the association between SCPC accreditation and improved care for patients with acute coronary syndrome.

Clinical research requires high-quality data collection. Data collected at the emergency department evaluation is generally considered more precise than data collected through chart abstraction but is cumbersome and time consuming. We test whether trained research assistants without a medical background can obtain clinical research data as accurately as physicians. We hypothesize that they would be at least as accurate because they would not be distracted by clinical requirements. ⋯ The relatively fair interrater reliability observed in our study is consistent with previous studies evaluating interrater reliability for cardiovascular disease in the inpatient setting. With respect to research data, we found that prospective ascertainment of clinical data is more often correct when done by research assistants compared with clinicians simultaneously evaluating patients.

Editor's capsule summary for Cruz et al: (1) WHAT IS ALREADY KNOWN ON THIS TOPIC: Valid clinical research requires high-quality data collection. Physicians are commonly considered the standard by which valid prospective data are obtained. WHAT QUESTION THIS STUDY ADDRESSED: This study determined whether non-medically trained research assistants could reliably collect subjective historical data from emergency department patients with chest pain. ⋯ Research assistants demonstrated fair to excellent reliability (as defined by crude agreement and kappa) when obtaining cardiac histories and cardiac risk factors. HOW THIS MIGHT CHANGE CLINICAL PRACTICE: The results of this study will not change clinical practice. They do, however, provide evidence to support the use of trained research assistants for the collection of certain types of clinical data.
