EP08.08: Improving estimated fetal weight accuracy at a tertiary centre: a quality improvement intervention

Implementation of improvement strategies targeting identified error drivers of EFW identified by a quality assurance project in a tertiary healthcare centre in Canada. Based on previous reported quality improvement project at our centre, we proposed a lean goal of improving the error by 15% by sonographer education and incorporation of feedback. We audited our population 6 months after the intervention. 2 PDSA cycles were conducted. Images obtained within 14 days from delivery were analysed by independent examiner. The framework from 2019 ISUOG biometry guidelines scoring was used. Results were reported as descriptive statistics. Pre- and post-intervention were compared by T-test (P<.05). EFW error was found in 81 (5%) from 20% preintervention. When analysing images individually and comparing EFW parameters head-to-head for the scans with error, there were statistically significant improvements. Accurate EFW is critical for clinical decision-making and is a quality measure in antenatal care. Identifying key sonographic error drivers, education and feedback led to significant improvement.
