Evaluation and treatment of infective endocarditis in children and adolescents with underlying CHD: a Paediatric Acute Care Cardiology Collaborative Clinical Practice Guideline.

BACKGROUND

Infective endocarditis is a leading cause of morbidity and mortality in children and adolescents with underlying CHD. Appropriate diagnostic workup and management in the inpatient setting can be challenging in this patient population due to the spectrum of disease complexity and the dynamic nature of the field. Therefore, the Paediatric Acute Care Cardiology Collaborative has undertaken the creation of this clinical practice guideline.

METHODS

A panel of paediatric cardiologists, infectious disease specialists, intensivists, advanced practice practitioners, pharmacists, cardiothoracic surgeons, and a dentist was convened. The literature was systematically reviewed for relevant articles on the management of infective endocarditis in patients with CHD. Using the modified Delphi technique, recommendations were generated and put through iterative Delphi rounds to achieve consensus for inclusion.

RESULTS

Based on 127 articles that met the inclusion criteria, 82 recommendations were generated, 50 of which achieved consensus for inclusion and are included in this guideline. They address risk factors specific to CHD lesion type and prior interventions including implanted material, diagnostic considerations, management strategies, and recommendations on counselling other healthcare providers, patients, and families. Of the 50 consensus recommendations, 36 are strong recommendations, though 20 have low or very low quality of evidence.

CONCLUSIONS

A central theme in this guideline is that an individual's specific CHD lesion and prior interventions must be carefully considered for risk stratification, diagnostic approach, and management. While most are strong recommendations, many are supported by low quality of evidence, emphasising the need for further research in this subject.
