OBJECTIVES: The objective of this study was to assess contemporary use of operator directed sedation (ODS) and anesthesiologist care (AC) in the pediatric/congenital cardiac catheterization laboratory (PCCL), specifically evaluating whether the use of operator-directed sedation was associated with increased risk of major adverse events.

BACKGROUND: The safety of ODS relative to AC during PCCL procedures has been questioned.

METHODS: A multicenter, retrospective cohort study was performed studying procedures habitually performed with ODS or AC at IMPACT (Improving Adult and Congenital Treatment) registry hospitals using ODS for ≥5% of cases. The risks for major adverse events (MAE) for ODS and AC cases were compared, adjusted for case mix. Current recommendations were evaluated by comparing the ratio of observed to expected MAE for cases in which ODS was inappropriate (inconsistent with those guidelines) with those for similar risk AC cases, as well as those in which ODS or AC was appropriate.

RESULTS: Of the hospitals submitting data to IMPACT, 28 of 101 met inclusion criteria. Of the 7,042 cases performed using ODS at these centers, 88% would be inappropriate. Use of ODS was associated with lower likelihood of MAE both in observed results (p < 0.0001) and after adjusting for case-mix (odds ratio: 0.81; p = 0.006). Use of AC was also associated with longer adjusted fluoroscopy and procedure times (p < 0.0001 for both). The observed/expected ratio for ODS cases with high pre-procedural risk (inappropriate for ODS) was significantly lower than that for AC cases with comparable pre-procedural risk. Across a range of pre-procedural risks, there was no stratum in which risk for MAE was lower for AC than ODS.

CONCLUSIONS: Across a range of hospitals, ODS was used safely and with improved efficiency. Clinical judgment better identified cases in which ODS could be used than pre-procedural risk score. This should inform future guidelines for the use of ODS and AC in the catheterization laboratory.

Radiation Safety in Children with Congenital and Acquired Heart Disease: A Scientific Position Statement on Multimodality Dose Optimization from the Image Gently Alliance.

<p>There is a need for consensus recommendations for ionizing radiation dose optimization during multi-modality medical imaging in children with congenital and acquired heart disease (CAHD). These children often have complex diseases and may be exposed to a relatively high cumulative burden of ionizing radiation from medical imaging procedures including cardiac computed tomography, nuclear cardiology studies and fluoroscopically guided diagnostic and interventional catheterization and electrophysiology procedures. Although these imaging procedures are all essential to the care of children with CAHD and have contributed to meaningfully improved outcomes in these patients, exposure to ionizing radiation is associated with potential risks, including an increased lifetime attributable risk of cancer. The goal of these recommendations is to encourage informed imaging to achieve appropriate study quality at the lowest achievable dose. Other strategies to improve care include a patient-centered approach to imaging, emphasizing education and informed decision making and programmatic approaches to ensure appropriate dose monitoring. Looking ahead, there is a need for standardization of dose metrics across imaging modalities, so as to encourage comparative effectiveness studies across the spectrum of CAHD in children.</p>
