摘要
OBJECTIVES:To analyze barriers to recruitment encountered during a prospective study in the PICU and evaluate strategies implemented to improve recruitment.
DESIGN:Prospective observational study of continuous electroencephalogram monitoring in comatose children.
SETTING:PICUs at four North American institutions.
PATIENTS:Patients with a Glasgow Coma Scale score of less than or equal to 8 for at least an hour.
INTERVENTIONS:Four strategies to increase recruitment were sequentially implemented.
MEASUREMENTS AND MAIN RESULTS:The baseline enrollment rate was 2.1 subjects/mo, which increased following the single-site introduction of real-time patient screening using an online dashboard (4.5 subjects/mo), deferred consenting (5.2 subjects/mo), and weekend screening (6.1 subjects/mo). However, the subsequent addition of three new study sites was the greatest accelerator of enrollment (21 subjects/mo), representing a 10-fold increase from baseline (p < 0.0001).
CONCLUSIONS:Identifying barriers to recruitment and implementing creative strategies to increase recruitment can successfully increase enrollment rates in the challenging ICU environment.
