Introduction: Many children require sedation for imaging. We aimed to reduce sedation for thoracic (chest and cardiac) computed tomography (CT) scans in children 0-4 years old from 65% to 20% by December 2018 and to sustain.
Methods: We counted baseline, intervention, and a follow-up period thoracic CT scans performed with sedation in children 0-4 years old. We developed a new volumetric target-mode electrocardiogram-gated CT imaging protocol to reduce scan time and control for factors that decrease image quality. Additional interventions included technologist training, communication to radiologists and clinicians, and eliminating a default request for sedation accompanying the electronic order for most thoracic CT scans. A statistical process control chart tracked data to study process changes over time.
Results: During the baseline and intervention periods, 232 of 357 and 217 of 794 scans required sedation. Interventions created 2 centerline shifts. Overall, thoracic CT scans in children 0-4 years old requiring sedation decreased from 65% to 24% and was sustained 5 years later. No patients during the baseline period, one (1 of 794, 0.1%) during the intervention period and 2 (2 of 480, 0.4%) during the audit period 5 years later, initially had nondiagnostic nonsedated scans that required an additional scan with sedation.
Conclusions: We developed a volumetric target-mode electrocardiogram-gated CT protocol, eliminated default sedation ordering, and trained and educated staff to reduce sedation in young children undergoing thoracic CT scans. The frequency of sedation for thoracic CT in children 0-4 years old decreased from 65% to 24% and was sustained after revising imaging parameters and eliminating a default sedation order.
