Pediatric Syncope: Is the Diagnostic Guideline Implemented and Adhered to?

Background: We sought to investigate adherence to the current pediatric syncope guideline in the emergency department and its impact on the frequency of missed or unnecessary diagnostic measures. For the first time, in 2014 updated guideline defines indispensable basic diagnostic measures and a consecutive algorithm for safe clinical decision making.

Patients and method: We analyzed retrospectively 314 pediatric patients, 166 were presented before and 148 after publication of this guideline update.

Results: After guideline publication, 54 patients (36.5%) were not treated in accordance with the guideline and 2 (0.63%) cases caused by epileptic seizures were initially misdiagnosed as reflex syncope. Among these 54 patients, 32 (59.3%) inpatient admissions were inappropriate, as well as 11 (20.4%) electroencephalographies, 4 (7.4%) sleep-deprivation EEGs, 2 (3.7%) magnetic resonance imaging, 5 (9.3%) urine diagnostics and 32 (59.3%) blood tests. In 21 cases (38.9%), the medical history was insufficient. ECG was missed in 42 patients (77.8%). There was no significant difference between the pre- and post-guideline groups concerning diagnostic work-up (p=0,12).

Discussion: This non-compliance with the guideline did not cause a large number of misdiagnosed epileptic seizures (1.4%) or adverse outcomes but led to waste of resources in healthcare system and undue burdens on patients and their families.

Conclusion: In addition to establishment of clinical guidelines, the need for additional measures and strategies to promote their implementation seems obvious.
