Please update your RDS app to v4.7.3

We asked you in January to update to v4.7.2.  After the deployment planned for 27th February, this new update will be needed to ensure that you are able to download RDS toolkits even when the RDS website is not available. We will wait until as many users as possible have downloaded the new version before switching off the old system for app downloads and moving entirely to the new approach.

To check your current RDS version, click on the three dots bottom right of the RDS app screen. This takes you to a “More” page where you will see the version number. 

To update to the latest release:

 On iPhones – go to the Apple store, click on your profile icon top right, scroll down to see the apps waiting to be updated and update the RDS app.

On Android phones – these can vary, but try going to the Google Play store, click on your profile icon top right, click on “Manage apps and device”, select and update the RDS app.

Right Decision Service newsletter: February 2025

Welcome to the February 2025 update from the RDS team

1.     Next release of RDS

 

A new release of RDS is planned (subject to outcomes of current testing) for week beginning 24th February. This will deliver:

 

  • Fixes to mitigate the recurring glitches with the RDS admin area and the occasional brief user interface outages which have arisen following implementation of the new distributed technology infrastructure in December 2024.

 

  • Capability to embed content from Google calendar, Google Maps, Daily Motion, Twitter feeds, Microsoft Stream into RDS pages.

 

  • Capability to include simple multiplication in RDS calculators.

 

The release will also incorporate a number of small fixes, including:

  • Exporting of form within Medicines Sick Day Guidance in polypharmacy toolkit
  • Links to redundant content appearing in search in some RDS toolkits
  • Inclusion of accordion headers alongside accordion text in search result snippets.
  • Feedback form on mobile app.
  • Internal links on mobile app version of benzo tapering tool

 

We will let you know when the date and time for the new release are confirmed.

 

2.     New RDS developments

There is now the capability to publish toolkits on the web with left hand side navigation rather than tiles on the homepage. To use this feature, turn on the “Toggle navigation panel” option at the top of the Page settings menu at toolkit homepage level – see below. Please note that publication to downloadable mobile app for this type of navigation is still under development.

The Benzodiazepine tapering tool (https://rightdecisions.scot.nhs.uk/benzotapering) is now available as part of the RDS toolkit for the national benzodiazepine prescribing guidance developed by the Scottish Government Effective Prescribing team. The tool uses this national guidance developed with a wide-ranging multidisciplinary group. This should be used in combination with professional judgement and an understanding of the needs of the individual patient.

3.     Archiving and version control and new RDS Search and Browse interface

Due to the intensive work Tactuum has had to undertake on the new technology infrastructure has pushed back the delivery dates again and some new requirements have come out of the recent user acceptance testing. It now looks likely to be an April release for the search and browse interface. The archiving and version control functionality may be released earlier. We’ll keep you posted.

4.     Statistics

At the end of January, Olivia completed the generation of the latest set of usage statistics for all RDS toolkits. If you would like a copy of the stats for your toolkit, please contact Olivia.graham@nhs.scot .

 

5.     Review of content past its review date

We have now generated reports of all RDS toolkit content that has exceeded its review date by 6 months or more. We will be in touch later this month with toolkit owners and editors to agree the plan for updating or withdrawing out of date content.

 

6.     Toolkits in development

Some important toolkits in development by the RDS team include:

  • National CVD prevention pathways – due for release end of March 2025.
  • National respiratory pathways, optimal cancer diagnostic pathways and cancer prehabilitation pathways from the Centre for Sustainable Delivery. We will shortly start work on the national cancer referral pathways, first version due for release via RDS around end of June 2025.
  • HIS Quality of Care Review toolkit – currently in final stages of quality assurance.

 

The RDS team and other information scientists in HIS have also been producing evidence summaries for the Scottish Government Realistic Medicine team, to inform development of national guidance around Procedures of Limited Clinical Value. This guidance will in due course be translated into an RDS toolkit.

 

7. Training sessions for new editors (also serve as refresher sessions for existing editors) will take place on the following dates:

  • Friday 28th February 12-1 pm
  • Tuesday 11th March 4-5 pm

 

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.)

 

To invite colleagues to sign up to receive this newsletter, please signpost them to the registration form  - also available in End-user and Provider sections of the RDS Learning and Support area.   If you have any questions about the content of this newsletter, please contact his.decisionsupport@nhs.scot  If you would prefer not to receive future newsletters, please email Olivia.graham@nhs.scot and ask to be removed from the circulation list.

Cow's milk protein allergy in infants, Paediatrics (300)

Objectives

This guideline is intended for use by all health professionals in the acute and primary care settings for the diagnosis and management of infants and young children (up to two years) with symptoms of suspected cow’s milk protein allergy (CMPA).

The following steps should be followed

  • Undertake an allergy focused clinical history
  • Refer to the signs and symptoms guide to determine the diagnosis
  • Follow the appropriate pathway for IgE and non IgE mediated CMPA
  • Refer to the NHSGGC Formulary, Hypoallergenic formula for  the management of cow’s milk allergy in Children, for guidance on  the appropriate formula

Allergy focused clinical history

If cows' milk protein allergy is suspected, take an allergy-focused clinical history tailored to the presenting symptoms and the age of the infant.

 Allergy-focused clinical history (Start from birth)1, 2

History of reaction 

Age of first onset:

(soon after birth, first introduction of formula to breast fed baby or around starting complementary feeding)

Type of feeding:

(breast, formula fed or mixed fed infant)

Breastfed infants:

  • Has the infant had any previous exposure to formula milk? e.g. given a formula top up at the time of birth
  • Does the mother consume dairy products? Is it a milk free diet? 
  • Details of any changes in maternal diet and apparent response to such changes, e.g. any response to the symptoms on elimination of milk and milk containing products and/or soya
  • Details of any feeding difficulties, e.g. positioning and attachment issues, aversion

The likelihood of symptoms being related to milk is much lower in exclusively breast fed infants than in formula fed infants.3, 4, 5

Formula fed infants

  • Age formula introduced
  • Any changes to formula e.g. extensively hydrolysed formula (eHF)
  • Any feeding difficulties e.g. food aversion, refusal of feeds 
  • Volume of milk offered (should not exceed 180ml/kg)

Mixed fed infants (Breast & Formula)

  • Age formula introduced
  • Any changes to formula e.g. eHF
  • Any feeding difficulties, e.g. food aversion, refusal of feeds
  • Did the symptoms only present when cow's milk based formula was given to a breast fed infant
  • Volume of milk offered (should not exceed 180ml/kg)

Weaning Period

Age when weaning foods introduced and types of foods
If symptoms presented when milk products were introduced into the weaning diet but no reaction to formula then it is unlikely to be CMPA

Time to reaction 

Immediate: usually within minutes

Delayed: usually after ≥ 2 hours to days

What were the symptoms/signs, the sequence and the severity;

respiratory symptoms (e.g. wheeze/breathing difficulties), signs of hypotension (e.g. lethargy, floppy), gastrointestinal symptoms (e.g. vomiting, loose stools, bowel motions alternating between diarrhoea and constipation, skin symptoms (urticaria, eczema)

How long to resolve?

e.g. minutes-hours or days

Treatment received and response?

e.g. antihistamines, anti reflux treatment, laxatives, hypoallergenic formula milk

Details of any changes in diet and apparent response to such changes.

e.g. changes in formula milk; anti-reflux, partially hydrolysed, extensively hydrolysed, amino acid or soya infant milk.

Reproducibility of symptoms/signs on repeat exposure 

Growth history

Weight (centiles)

Height (centiles)

Head circumference (centiles)

Does the infant's weight:
  • follow the centiles, or 
  • is the weight static, or
  • is there a significant drop on the centiles (2 or more)?

History of eczema (atopic dermatitis)

Signs of eczema;

(e.g. eczematous patches; dry inflamed/infected skin)

Affected areas

(e.g. Facial, flexural or trunk)

Severity and response to treatment

(first line treatment; mild to moderate potency topical steroids and moisturizers)

 

Family history of atopy

History of atopic diseases (e.g. asthma, allergic rhinitis, food allergy or eczema) or food allergy in parents or siblings. 
If allergy to CMPA is suspected please follow the algorithm for non-IgE or IgE (under development) mediated cows milk protein allergy

Signs and symptoms of cow's milk protein allergy

The table below depicts the list of possible signs and symptoms of CMPA and should be used in conjunction with the allergy focused history. The non-IgE signs and symptoms are common in infants and can be related to causes other than CMPA3. This guideline must be used in conjunction with the allergy focused history.

A small number of infants can present with features of both IgE and non-IgE mediated symptoms.

Non-IgE mediated

Delayed onset symptoms (within 48hrs - 72hrs post ingestion) 

IgE mediated

Mostly immediate onset of symptoms (within minutes or up to 2hrs post ingestion)

The clinical features of non-IgE CMPA are variable in type and severity so the diagnosis can be challenging.

NICE CDG/ESPGHAN recommend that a differential diagnosis should be considered based on the findings of a thorough allergy focused history. 

Many of the symptoms associated with CMPA can occur as a result of other common conditions, or as variants of normal, so it is important to consider CMPA as only one in a range of possible diagnoses.

There is a wide range in the severity of symptoms from skin symptoms only to life threatening reactions anaphylaxis.

Skin

  • Pruritis (itch)
  • Erythema
  • Atopic eczema
Gastrointestinal Tract
  • Repeated episodes of gastro-oesophageal reflux persistent or not responding adequately to 1st line treatment
  • Vomiting
  • Constipation, or soft stools with excessive straining 
  • Diarrhoea
  • Mucus and/or blood in stools (in otherwise well baby)
  • Abdominal pain (discomfort, painful flatus)
  • Infantile colic (irritability); prolonged & persistent (>3hrs/day, >3 times/week, >3 weeks)
  • Feed refusal/aversion
  • Faltering growth and one or more of the above gastrointestinal symptoms

Consider cows milk protein allergy only if symptoms not responding to 1st line treatment.

See NHSGGC Guideline on the Management of Eczema in Children for more info
