Performance audits
Audit UTPI performance
- The measured UTPI is influenced by gestational age, maternal age, weight, racial origin and history of PE in the previous pregnancy.
- To assess the quality of your measurements you need to upload an excel file providing data for each patient. For instructions on how the excel file should be formatted, please click here.
- The application will use these data to calculate the MoM values for each case. It will then assess the results and highlight whether your values are within or outside acceptable limits. The distribution of your measurements, adjusted for maternal factors, will be presented in a graph of UTPI against gestational age.
- If your results are outside acceptable limits, you will need to review your technique for measuring UTPI.
