Cumulative sum (CUSUM) chart for comparison of the learning curves for the sonographical fetal weight estimation

Objectives: The assessment of young specialists performing sonographical fetal weight estimation is an important aspect of quality assurance in the department of obstetrics. Therefore, the aim of the study was to evaluate the learning curve of sonographical fetal weight estimation in term pregnancies using CUSUM analysis. Patients and methods: 677 fetal biometry data from routine ultrasound scans, performed by three trainees between 2004–2007, were recruited.
