Vasa previa is defined as aberrant fetal blood vessels crossing over or within 2 cm of the internal cervical os. These blood vessels are unprotected by the umbilical cord or placenta and run through the amniotic membranes¹.
There are two types of vasa previa. Type 1 occurs when abnormal fetal vessels connect a velamentous cord insertion to the main body of the placenta. Type 2 occurs when fetal vessels connect a bilobed placenta or a placenta with succenturiate lobe¹.

A retrospective data collection of 100 consecutive cases of mid trimester obstetric ultrasounds performed at our practice in March 2020 was done. Assessment of the study for saved images on PACS with a colour box over the lower uterine segment with internal os was performed.
Data was compiled and analysed with particular emphasis on documented evidence of assessment for vasa previa by the sonographer. We presented the data amongst the sonographers across our practices in November and December 2020.
Following the presentation of the findings...
Imaging findings OR Procedure details
ACDS audits have found a wide variety of issues which have contributed to Action Level and OoT audit outcomes since 2010. However, the type of issues being uncovered have changed with fundamental supporting equipment, barometers and thermometers for example, rarely contributing to poor audit outcomes over the past five years. The raw data is shown in Table 1:

This brief review has demonstrated that ACDS audits positively impact the safety of Australian radiotherapy delivery. The number of recommendations and individual findings which have resulted in clinics changing their practice indicate that the hypothesis is proven. However, in performing this investigation, it has become apparent that the ACDS data needs to be re-structured and held within a database which could be interrogated by ACDS staff and customers. To achieve this, the ACDS engaged a programmer tasked with building a database, enabling appropriate data management...
