- W4381386144 abstract "Introduction: Ultrasound is the standard imaging technique for diagnosing lower limb deep venous thrombosis (DVT). The National Institute for Health and Care Excellence (NICE) guidance 158 recommendation 1.1.3 states that all patients with sufficient pretest probability for DVT should be offered a proximal leg vein ultrasound within four hours. However, due to high patient volumes, formal radiology department ultrasound wait times often exceed one week. Point-of-care ultrasound (POCUS) is used to bridge diagnostic delay in our emergency department (ED) . This study aimed to quantify numbers offered POCUS for suspected proximal lower DVT in our ED and accuracy of such studies. Method: A retrospective review of electronic records was conducted for patients who underwent formal lower-limb ultrasound for suspected DVT at our hospital over a three-month period (August 1, 2022-October 12, 2022). Patient charts for all ED presentations were assessed to determine whether POCUS was offered and whether DVT was diagnosed. Statistical analysis was conducted using PRISM v9. Results: 80 formal ultrasound scans were performed at our hospital for lower limb DVT. 58 were requested for patients presenting to ED, of which 42 had complete records available meeting selection criteria. POCUS was offered to 24 patients in ED (57.1%). Sensitivity was 66% (95% CI 12%- 98%), and specificity was 94.1% (95% CI 75%-99%). Overall accuracy was 90%, with only one false negative study identified at formal follow-up ultrasound. Conclusion: Although sample size was small, our results suggest that POCUS is an accurate but underused tool to diagnose lower limb DVT. Developing a standardized protocol for performing and reporting POCUS DVT scans in ED should allow for earlier diagnosis and initiation of appropriate treatment where necessary." @default.
