Comparative Effectiveness Research in Pediatric Respiratory Disease: Promise and Pitfalls

Comparative effectiveness research (CER) has become increasing central to clinical research in medicine. CER seeks to conduct clinical trials that compare different commonly used interventions in real-world settings (pragmatic clinical trials) and use a multitude of sources of evidence (including registries and cohort studies) to inform clinical decision making. CER also ensures that stakeholders (patients, families, care providers, insurers) have a voice in the research process by integrating formal stakeholder engagement as part of the research. This innovative approach to clinical research has distinct benefits and pitfalls. This review first defines what CER is and then describes some of its benefits and then pitfalls. The focus is on the role of CER in pediatrics.
