Right Decision Service newsletter: September 2024

Welcome to the Right Decision Service (RDS) newsletter for September 2024.

1.Business case for permanent provision of the Right Decision Service from April 2025 onwards

This business case has now been endorsed by the HIS Board and will shortly be submitted to Scottish Government.

2. Management of RDS support tickets

To balance increasing demand with available capacity and financial resource, the RDS team and Tactuum are now working together to  implement closer management of support tickets. As a key part of this, we want to ensure clear, timely and consistent communication with yourselves as requesters.  

Editors will now start seeing new messages come through in response to support ticket requests which reflect this tightening up and improvement of our processes.

Key points to note are:

2.1 Issues confirmed by the RDS and Tactuum teams as meeting the critical/urgent and high priority criteria will continue to be prioritised and dealt with immediately.

Critical/urgent issues are defined as:

  1. The Service as a whole is not operational for multiple users. OR
  2. Multiple core functions of the Service are not operational for multiple users.

Example – RDS website outage.

Please remember to email ann.wales3@nhs.scot and his.decisionsupport@nhs.scot with any critical/urgent issues in addition to raising a support ticket.

High priority issues are defined as:

  1. A single core function of the Service is not operational for multiple users. OR:
  2. Multiple non-core functions of the Service are not operational for multiple users.

Example – Build to app not working.

2.2 Support requests that are outwith the warranty period of 12 weeks since the software was originally developed will not be automatically addressed by Tactuum. The RDS team will consider these requests for costed development work and will obtain estimate of effort and cost from Tactuum for priority issues.

2.3 Support tickets for technical issues that are not classified as bugs will not be automatically addressed by Tactuum. The definition of a bug is ‘a defect in the software that is at variance with documented user requirements.’  Issues that are not bugs will also be considered for costed development work.

The majority of issues currently in support tickets fall into category 2 or 3 above, or both.

2.4 Non-urgent requests that require a deployment (i.e a new release of RDS) will normally be factored into the next scheduled release (currently end of Nov 2024 and end of Feb 2025) unless by special agreement with the RDS team.

Please note that we plan to move in the new year to a new system whereby requests all come to an RDS support portal in the first instance and are triaged from there to Tactuum when appropriate.

We will be organising a webinar in a few weeks’ time to take you through the details of the current support processes and criteria.

3. Next scheduled deployment.

The next scheduled RDS deployment will take place at the end of November 2024.  We are reviewing all outstanding support tickets and feature requests along with estimates of effort and cost to determine which items will be included in this deployment.

We will update you on this in the next newsletter and in the planned webinar about support ticket processes.

4. Contingency arrangements for RDS

Many thanks to those of you who attended our recent webinar on the contingency arrangements being put in place to prevent future RDS outages as far as possible and minimise impact if they do occur.  Please contact ann.wales3@nhs.scot if you would like a copy of the slides from this session.

5. Transfer of CKP pathways to RDS

The NES clinical knowledge pathway (CKP) publisher is now retired and the majority of pathways supported by this tool have been transferred to the RDS. Examples include:

NHS Lothian musculoskeletal pathways

NHS Fife rehabilitation musculoskeletal pathways

NHS Tayside paediatric pathways

6. Other new RDS toolkits

Include:

Focus on frailty (from HIS Frailty improvement programme)

NHS GGC Money advice and support

If you would like to promote one of your new toolkits through this newsletter, please contact ann.wales3@nhs.scot

To go live imminently:

  • Focus on dementia
  • NHS Lothian infectious diseases toolkit
  • Dumfries and Galloway Adult Support and Protection procedures
  • SIGN guideline – Prevention and remission of type 2 diabetes

 

7. Evaluation projects

We have recently analysed the results of a survey of users of the Scottish Palliative Care Guidelines toolkit.  Key findings from 61 respondents include:

  • Most respondents (64%) are frequent users of the toolkit, using it either daily or weekly. A further 25% use it once or twice per month.
  • 5% of respondents use the toolkit to deliver direct patient care and 82% use it for learning
  • Impact on practice and decision-making was rated as very high, with 80% of respondents rating these at a 4-5 on a 5 point scale.
  • Impact on time saving was also high, with 74% of respondents rating it from 3-5.
  • 74% also reported that the toolkit improved their knowledge and skills, rating these at 4-5 on the Likert scale

Key strengths identified included:

  • The information is useful, succinct, and easy to understand (31%).
  • Coverage is comprehensive (15%)
  • All information is readily accessible in one place and users value the offline access via mobile app (15%)
  • Information is reliable, evidence-based and up to date (13%)

Users highlighted key areas for improvement in terms of navigation and search functionality. The survey was very valuable in enabling us to uncover the specific issues affecting the user experience. Many of these can be addressed through content management approaches. The issues identified with search results echo other user feedback, and we are costing improvements with a view to implementation in the next RDS deployment.

8.RDS High risk prescribing (polypharmacy) decision support embedded in Vision and EMIS primary care E H R systems

This decision support software, sponsored by Scottish Government Effective Prescribing and Therapeutics Division,  is now available for all primary care clinicians across NHS Tayside. Board-wide implementation is also planned for NHS Lothian, and NHS GGC, NHS Ayrshire and Arran and NHS Dumfries and Galloway have initial pilots in progress. The University of Dundee has been commissioned to evaluate impact of this decision support software on prescribing practice.

9. Video tutorials for RDS editors

Ten bite-size (5 mins or less) video tutorials for RDS editors are now available in the “Resources for providers of RDS tools” section of the RDS.  These cover core functionality including Save and preview, content page and media management, password management and much more.

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

  • Wednesday 23rd October 4-5 pm
  • Tuesday 29th October 11 am -12 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.)

Maternal Sepsis (572)

Please report any inaccuracies or issues with this guideline using our online form

NB  Sepsis can kill mothers AND babies. If either of this pairing is infected ensure that those looking after the mother/baby know about this promptly to ensure risk evaluation of cross-infection is made.

Sepsis remains an important cause of maternal death (1). The development of sepsis is often insidious and the physiological adaptations in normal pregnancy may mask developing sepsis or make it more difficult to identify. Once infection becomes systemic the woman’s condition can deteriorate extremely rapidly over the course of a few hours into septic shock, disseminated intravascular coagulation and multi-organ failure2. A high index of suspicion should be maintained.

Briefly learn that SIRS > sepsis > septic shock unless appropriate action taken

 SIRS (systemic inflammatory response syndrome) -  a  clinical state consisting of two or more coexisting conditions: fever or hypothermia, tachycardia, tachypnoea, and an abnormally high leukocyte count.

Severe sepsis with acute organ dysfunction has a mortality rate of 20-30%, rising to 40-50% if septic shock (sepsis with hypotension refractory to fluid resuscitation) develops. Severe Sepsis with multi-organ failure carries a mortality rate >60%3.

The purpose of this guideline is to provide a structured approach to investigation and management of these women. The screening tool is to be filed in the patient notes and completed goals documented.

  • IT IS IMPORTANT TO NOTE THAT MOST LABOURING WOMEN WILL MEET NON-PREGNANT “SIRS” CRITERIA: see MODIFIED MATERNITY SEPSIS TOOL BELOW
  • SIMILARLY, NON-PREGNANT RISK ASSESSMENTS (eg CURBS 65) DO NOT PERFORM WELL IN THE PREGNANT POPULATION.
  • IF IN DOUBT MANAGE AS SEPSIS AND THEN REVIEW DIAGNOSIS.

Signs and symptoms

Modified Early Warning Scoring System charts should be used to aid timely recognition, treatment and referral of women who have or who are developing a critical condition. These do not take into account the physiological changes in pregnancy, however, they allow a trend in the patients’ observations to be documented and acted upon. SEE SEPSIS SCREENING TOOL BELOW

In labour changes in some parameters are highlighted in red and should be considered. Err on overdiagnosis / response if in doubt

Temperature <36°C or >38°C 4

In labour a temperature of ≥ 37.5°C on 2 separate occasions at least 2 hours apart

Persistent tachycardia > 100bpm5
Or

>110bpm in labour

Tachypnoea >20 breaths per minute4
Or

>22 in labour

WCC <4 or >16 x 109 /L  4

WCC in labour >20 x 109 /L(although WCC of up to 30 have been seen in labour, a WCC of 20 is the generally recommended threshold for investigation in the literature)3,5

Oliguria <0.5mls/hour4

Arterial Hypoxaemia <8k Pa on air and/or metabolic acidosis pH <7.35 / H+ >45nmol/l

(pregnancy results in a relative respiratory alkalosis)4

Hypotension MAP <65mmHg or systolic BP <90mmHg4

Abnormal U&Es, LFTs , Coagulation 

CRP – However a normal CRP may be falsely reassuring and does not rule out systemic sepsis.  There is often a delay in CRP increase in acute sepsis.

Fetal tachycardia and/or non reassuring CTG

  • this can be evidence of intrauterine infection / choriomamnioitis
  • these changes may serve as an early warning sign for derangements in maternal end-organ systems  

Hyperglycaemia in the absence of diabetes


The Common Organisms

The organisms most commonly implicated are2:

  • Streptococcus pyogenes ( Group A strep)
  • Group B streptococcus 
  • Escherichia coli
  • Staphylococcus aureus
  • Gram- positive and gram – negative mixed infections
  • Streptococcus pneumoniae
  • Klebsiella
  • Enterococcus faecalis
  • MRSA

Investigations

Seek the organism

This should ideally be guided by the history and take place before administration of antibiotics – HOWEVER, do not delay starting antibiotic therapy.

  • Take a History and examine the patient
  • Blood cultures
  • Midstream specimen of urine
  • Stool cultures
  • Vaginal swabs
  • Wound/perineal swabs
  • Placental swabs if delivered
  • Baby/fetal swabs if delivered
  • Chest X ray
  • Throat swabs
  • Imaging of the abdomen if suspected intra-abdominal sepsis
  • Breast examination
  • Wound examination
  • Consider the need for:
    • Lumbar puncture
    • Respiratory secretions culture

Bloods

  • FBC +/- blood film
  • COAGULATION STUDIES
  • UREA AND ELECTROLYTES
  • CRP
  • LFT
  • LACTATE
  • Group and Save (X-match if appropriate : see separate MSBOS)
  • Consider Blood Gas analysis (NOT ROUTINE)

Serum lactate

A measure of tissue perfusion and prognostic indicator4.  This can be performed on a venous or arterial blood gas.  A lactate of >4 mmol/l is indicative of tissue hypoperfusion.

  • 2.1- 3.9 Intermediate
  • > 4 Severe

Management

Antibiotics

  • Broad spectrum intravenous antibiotics can be life saving. Immediate aggressive treatment should be initiated as each hour of delay is associated with a measurable increase in mortality3. 
  • Microbiology advice should be sought in severe sepsis or septic shock.
  • Breastfeeding may limit the use of some antimicrobials.
  • If no response after 24-48hrs of antibiotics consider change/addition of antibiotics under microbiology guidance.

See the Antibiotics Policy for Obstetric Patients GG&C guideline. The following table summarises GGC Antibiotic guidance in SEPSIS only. 

Haemodynamic Management

  • Loss of vasomotor tone, myocardial depression and increased vascular permeability contribute to the real risk of pulmonary oedema3. Fluid therapy should be titrated against the womans urine output, blood pressure and central venous pressure (if CVP line in place).
  • Initial fluid bolus of 500mls Hartmanns over 30 mins (caution in PET)
  • Hourly urine output >25mls/hr
  • Mean arterial pressure >65mmHg (used in discussion with anaesthetics)
    • Vasopressors indicated if the MAP is <65mmHg after adequate fluid resuscitation 
  • Consideration of central venous monitoring
    • if CVP line in place aim for CVP 8-12 mmHg 

 

Blood Products

  • Transfuse if Hb<70g/L until in the range 70 to 90g/L2
  • Keep platelet >50 x109/L if there is a significant risk of bleeding or if surgery or invasive procedures are planned
  • Be guided by haematological advice

 

Focus of infection

The focus of infection may need surgical evacuation, drainage or excision of necrotic tissue , e.g. uterine evacuation or breast, wound or pelvic abscess drainage 

 

Thromboprophylaxsis

  • TEDS
  • Low molecular weight heparin2
    • Prophylactic dose based on most recent weight
    • Once platelet count reviewed

 

The Fetus

  • The decision regarding timing and mode of delivery will be made by a consultant obstetrician.
  • During the intrapartum period continuous electronic fetal monitoring should be employed in gestations from 26+0 weeks. Below this gestation, discuss fetal monitoring with the Consultant Obstetrician. 
  • If delivery is required the choice of anaesthesia will be made after discussion with a Consultant Anaesthetist.
  • The paediatric team must be informed of any neonate born to a mother with suspected sepsis

 

Multidisciplinary Team

  • Consultant Obstetrician
  • Consultant Anaesthetist
  • Intensive care specialists
  • Microbiology
  • Haematology
  • Appropriate specific specialty (e.g. Surgical, renal etc.)
  • Pharmacy

 

Indications for Referral to ITU2

  • Cardiovascular - Hypotension or raised serum lactate persisting despite fluid resuscitation, suggesting the need for inotrope support
  • Respiratory - Pulmonary oedema/ Mechanical ventilation/ Airway protection
  • Renal - Renal dialysis
  • Neurological - Significantly decreased conscious level
  • Miscellaneous - Multi-organ failure/ Uncorrected acidosis/ Hypothermia

Referral to ITU should be from a discussion with the consultant obstetrician and consultant anaesthetist.

Once referral for ITU care has been made, the patient should continue receiving at least level 2 care until transferred out of the Obstetric HDU.  This includes maintaining CVP ≥ 8 mmHg, MAP >65mmHg (used in discussion with anaesthetics) and monitoring of appropriate bloods.

There is no place in this guideline for the use of high dose corticosteroids or recombinant human activated protein C
