Abstract | Introduction: Targeted ultrasound of the liver (TUSL) has been proposed as a new approach in chronic liver disease to meet the increasing demands on ultrasound services in this patient population. This study analyses the impact of TUSL on examination time. Methods: Retrospective cohort analysis of time taken to perform liver ultrasound on consecutive chronic liver disease patients pre‐ (n = 230) and post‐ (n = 147) introduction of TUSL. Within each cohort, patients were subdivided into three categories based on the clinical indication: Group 1. hepatocellular carcinoma (HCC) surveillance; Group 2. detection of cirrhosis, fibrosis or fatty liver; Group 3. detection of portal hypertension. The primary outcome was difference in examination time in the pre‐ and post‐intervention groups. Results: Introduction of TUSL led to 49% reduction in examination time (median (Q1–Q3) 23.7 (16.7–36.2) min in pre‐TUSL period vs 12.1 (6.4–19.5) min in post, P < 0.001) and it was consistent across all three clinical indication groups (gr1: median 23.1 minutes vs 8.1 minutes (P < 0.001), gr2: 23.0 minutes vs 14.3 minutes (P < 0.001), gr3: 32.2 minutes vs 15.3 minutes (P = 0.006)). After the adjustment for clinical indication and sonographer's experience, impact of TUSL on time reduction remained significant with a 66.6% time reduction (95% CI 53.6 to 79.5). Conclusion: Targeted ultrasound of the liver improves efficiency of chronic liver disease ultrasound with halving of examination times and consequently has the potential to greatly improve resource utilization. |
