Welcome to the Right Decision Service (RDS) newsletter for October 2024.
Development of the contingency solutions to maximise RDS resilience and minimise risk of future outages is in progress, aiming for completion by Christmas. As a reminder, these contingency arrangements are:
In the meantime, a gentle reminder to encourage users to download essential clinical toolkits to their mobile devices so that there is an offline version always available.
A new scheduled deployment with minor improvements drawn from support tickets, externally funded projects, information related to outages, and feature requests will take place in early December. Key improvements planned are:
We are also seeking approval to use the NHS Scotland logo and title for the RDS app on the app stores to help with audience engagement and clarity around the provenance of RDS.
We are still hopeful that user acceptance testing for at least the Search and browse enhancements can take place before Christmas. Thank you for your patience and understanding in waiting for these improvements. Timescales have been pushed back by old app migration challenges, work to address outages, and most recently implementing the contingency arrangements.
We are aware that there continue to be some issues around a number of RDS support tickets, in part due to constraints around visibility for the RDS team of the tickets in the existing support portal. We are investigating the potential to move to a new support ticket requesting system from early in the new year. We will organise the proposed webinar around support ticket processes once we have confirmed the way forward with the system.
There is a known issue with alterations in formatting of some RDS tables which seems to have arisen as a result of the 17 October deployment. Tactuum is working on a fix and on implementing additional regression testing to prevent this issue recurring.
Recently launched toolkits include:
NHS Lothian Infectious Diseases
Scottish Health Technologies Group – Technology Assessment recommendations
NHS Tayside Anaesthetics and Critical Care projects – an innovative toolkit which uses PowerAutomate to manage review and response to proposals for improvement projects.
If you would like to promote one of your new toolkits through this newsletter, please contact ann.wales3@nhs.scot
A number of toolkits are expected to go live before Christmas, including:
We have had a good response to the recent invitation to sign up to the new Teams channel for RDS editors. This provides a forum for editors to share learning, ideas and questions and we hope to hold regular webinars on topics of interest. The RDS team is in the process of joining participants to the channel and we’d encourage all editors to take part, using the registration form – available in Providers section of the RDS Learning and Support area.
The RDS team has worked with colleagues in NHS Grampian and the Digital Health & Care Innovation Centre to evaluate the impact of the Prevent the progress of diabetes web and mobile app in a small-scale pilot project. This app provides access to local and national resources and services targeted at people with prediabetes, a history of gestational diabetes, or candidates for remission. After just 8 weeks of using the app, 94% of patients reported increased their knowledge and understanding of diabetes, and 88% said it had increased their confidence and motivation to make lifestyle changes, highlighting specific behaviour changes. The learning from this project is informing development of a service model based on tailored support for patient groups with, high, medium and low digital self-efficacy.
Please contact ann.wales3@nhs.scot if you would like to know more about this project.
To book a place, please contact Olivia.graham@nhs.scot, providing your name, organisation, job role, and level of experience with RDS editing (none, a little, moderate, extensive.)

EDD should be calculated from the first scan ≥ 11+ 2 weeks gestational age (≥ 45mm).
If the initial scan is performed < 11+2 weeks gestation, the patient should have a return appointment at approximately 12-13 weeks gestation to perform optimal dating +/- NT measurements.
(Refer to Screening / Non-screening Pathways)
Upper and lower limbs must be assessed as well as cranial anatomy
Recommended criteria for measurement of CRL for pregnancy dating (UKNSC, 2015):
| CRL | DETAIL TO BE DEMONSTRATED |
| MIDLINE SECTION |
|
| POSITION |
|
| MAGNIFICATION |
|
| CALIPER PLACEMENT |
|
| IMAGE ARCHIVING |
|
The HC should be calculated using the recommended values of Altman and Chitty as per BMUS recommendations.
Technique for calculation of HC:
A cross-sectional view of the fetal head at the level of the ventricles should be obtained. The image should have the midline echo lying as close as possible to the horizontal plane.
The following landmarks should be identified and the image frozen:
If HC measurements cannot be made then EDD should be calculated using the femur length (FL)
Technique for calculation of FL:
The image should be obtained with the femur lying as close as possible to the horizontal plane. The full length of the bone should be visualised with soft tissue visible at both ends. Calipers should be placed at the centre of the ‘U’-shape at each end of the bone.
After 25 completed weeks the patient will be classed as ‘LATE BOOKER'.
All three measurement parameters [HC, AC and FL] should be obtained.
An EDD will be calculated from the HC measurement and entered on Badgernet. On the ultrasound report page type in comments ‘EDD based on HC >25 weeks GA’ and create a LATE BOOKER alert.
If there is discrepancy in the sizes between the fetuses, the EDD should be calculated from the largest fetus, using the criteria above.
Gestational age may be assessed from measurements of the mean sac diameter (MSD). This is calculated from the maximal diameters of the gestation sac (in mm) in the longitudinal and transverse views on transvaginal scan. The Mean gestation sac volume should be calculated where a transvaginal examination is declined using the full bladder technique.
An EDD should only be generated once a live embryo or fetus has been identified measuring ≥ 45mm.
