Design and reporting characteristics of clinical trials investigating sedation practices in the paediatric intensive care unit: a scoping review by SCEPTER (Sedation Consortium on Endpoints and Procedures for Treatment, Education and Research)

Sedation Research in Critically Ill Pediatric Patients: Proposals for Future Study Design From the Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research IV Workshop

OBJECTIVES

Sedation and analgesia for infants and children requiring mechanical ventilation in the PICU is uniquely challenging due to the wide spectrum of ages, developmental stages, and pathophysiological processes encountered. Studies evaluating the safety and efficacy of sedative and analgesic management in pediatric patients have used heterogeneous methodologies. The Sedation Consortium on Endpoints and Procedures for Treatment, Education, and Research (SCEPTER) IV hosted a series of multidisciplinary meetings to establish consensus statements for future clinical study design and implementation as a guide for investigators studying PICU sedation and analgesia.

DESIGN

Twenty-five key elements framed as consensus statements were developed in five domains: study design, enrollment, protocol, outcomes and measurement instruments, and future directions.

SETTING

A virtual meeting was held on March 2-3, 2022, followed by an in-person meeting in Washington, DC, on June 15-16, 2022. Subsequent iterative online meetings were held to achieve consensus.

SUBJECTS

Fifty-one multidisciplinary, international participants from academia, industry, the U.S. Food and Drug Administration, and family members of PICU patients attended the virtual and in-person meetings. Participants were invited based on their background and experience.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Common themes throughout the SCEPTER IV consensus statements included using coordinated multidisciplinary and interprofessional teams to ensure culturally appropriate study design and diverse patient enrollment, obtaining input from PICU survivors and their families, engaging community members, and using developmentally appropriate and validated instruments for assessments of sedation, pain, iatrogenic withdrawal, and ICU delirium.

CONCLUSIONS

These SCEPTER IV consensus statements are comprehensive and may assist investigators in the design, enrollment, implementation, and dissemination of studies involving sedation and analgesia of PICU patients requiring mechanical ventilation. Implementation may strengthen the rigor and reproducibility of research studies on PICU sedation and analgesia and facilitate the synthesis of evidence across studies to improve the safety and quality of care for PICU patients.

Pediatric Intensive Care Unit Patients: Sedation, Monitoring, and Neurodevelopmental Outcomes

The design and conduct of pediatric sedation studies in critically ill patients have historically been challenging due to the complexity of the pediatric intensive care unit (PICU) environment and the difficulty of establishing equipoise. Clinical trials, for instance, represent 1 important means of advancing our knowledge in this field, but there is a paucity of such studies in the literature. Accounting for ground-level factors in planning for each trial phase (eg, enrollment, intervention, assessment, and follow-up) and the presence of broader system limitations is of key importance. In addition, there is a need for early planning, coordination, and obtaining buy-in from individual study sites and staff to ensure success, particularly for multicenter studies. This review synthesizes the current state of pediatric sedation research and the myriad of challenges in designing and conducting successful trials in this particular area. The review poses consideration for future research directions, including novel study designs, and discusses electroencephalography monitoring and neurodevelopmental outcomes of PICU survivors.
