A "High-Reliability Organization" Approach to Improve Trauma Imaging Performance.

PURPOSE: CT is the gold standard for triaging critically ill patients, including in trauma, and its use has increased over time. CT turnaround times (TATs) are frequently targeted for improvement. As opposed to linear reductionist processes such as Lean and Six Sigma, a high-reliability organization (HRO) approach focuses on culture and teams to enable rapid problem solving. The authors evaluated the HRO model to rapidly generate, trial, select, and implement improvement interventions to improve trauma patient CT performance. METHODS: All trauma patients presenting to a single institution's emergency department during a 5-month period were included. Project periods included 2-month preintervention, 1-month wash-in, and 2-month postintervention. Each initial trauma CT encounter during the wash-in and postintervention periods created job briefs in which the radiologist ensured that all involved had the pertinent clinical information and agreed on the imaging needed, thereby creating a shared mental model as well as an opportunity to raise concerns and provide ideas for improvement. RESULTS: A total of 447 patients were included: 145 preintervention, 68 wash-in, and 234 postintervention. The seven selected interventions were trauma text alert; scripted CT technologist-radiologist communication; modification of CT acquisition, processing, sending, and interpretation; and trauma mobile phones. The seven selected interventions reduced trauma patient CT median TATs by 60% (78 vs 31 min, P < .001), demonstrating the effectiveness of an HRO approach to improvement. CONCLUSIONS: An HRO-based approach was rapid in generating, trialing, selecting, and implementing improvement interventions, and the interventions were effective at substantially decreasing trauma patient CT TATs.

Facial fractures: The "bottom-up" approach.

Given the demands of a busy high-volume trauma center, trauma radiologists are expected to evaluate an enormous number of images covering a multitude of facial bones in a short period of time in severely traumatized patients. Therefore, a comprehensive checklist, search pattern, and practical approach become indispensable for evaluation. Moreover, fracture complex classification conveys abundant information in a succinct shorthand fashion, which can be a large asset in a busy high-volume trauma center: reliably helping clinicians communicate urgent findings, make early treatment decisions, and effectively plan surgical approaches. Traditionally, radiologists' approach the CT axial dataset in top-down fashion: navigating their descent craniocaudal. However, a bottom-up approach may be advantageous, especially when it comes to facial fracture complex classification. Four key anatomic landmarks of the face, when evaluated sequentially in bottom-up fashion, are favorable to rapid single-sweep facial fracture characterization: the mandible, the pterygoid plates, the zygoma, and the bony orbits. That is, when done in succession: 1. Clearing the mandible rules out a panfacial smash fracture. 2. Clearing the pterygoid plates effectively rules out a Le Fort I, II, and III fracture. 3. Clearing the zygoma effectively rules out a zygomaticomaxillary complex (ZMC) type fracture. 4. Clearing the bony orbits effectively rules out a naso-orbital-ethmoid (NOE) fracture. Following this process of exclusion and elimination; as one ascends through the face, fracture characterization becomes more manageable and straightforward. Besides identifying all of the fractures and using the appropriate classification system, the radiologist also needs to recognize key clinically relevant soft tissue injuries that may be associated with facial fractures and thus should address these in the report.
