Synergistic Gentamicin for Endocarditis | Right Decisions

Announcements and latest updates

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

Contingency planning for RDS outages

Following the recent RDS outages, Tactuum and the RDS team have been reviewing the learning from these incidents. We are committed to doing all we can to ensure a positive outcome by strengthening the RDS to make it fully robust and clinically resilient for the future.

We would like to invite you to a webinar on 26^th September 3-4 pm on national and local contingency planning for future RDS outages. Tactuum and the RDS team will speak about our business continuity plans and the national contingency arrangements we are putting in place. This will also be a space to share local contingency plans, ideas and existing good practice. We would also like to gather your views on who we should send communications to in the event of future outages.

I have sent a meeting request for this date to all editors – please accept or decline to indicate attendance, and please forward on to relevant contacts. You can also contact Olivia.graham@nhs.scot directly to register your interest in participating.

2.National IV fluid prescribing calculator

This UK CA marked calculator is now live at https://righdecisions.scot.nhs.uk/ivfluids . It has been developed by a multiprofessional steering group of leads in IV fluids management, as part of the wider Modernising Patient Pathways Programme within the Centre for Sustainable Delivery. It aims to address a known cause of clinical error in hospital settings, and we hope it will be especially useful to the new junior doctors who started in August.

Please do spread the word about this new calculator and get in touch with any questions.

New toolkits

The following toolkits are now live;

Gender identity healthcare: adults and young people standards. (https://rightdecisions.scot.nhs.uk/genderidentity ) Note that this toolkit includes self-evaluation forms for each standard. A Scottish Government launch of these standards, together with the toolkit and NES educational resources, is planned for 3^rd September.
Care Inspectorate staffing method framework.
Vascular surgery pathways from the Modernising Patient Pathways Programme within the Centre for Sustainable Healthcare Delivery.

Updated guidance on current and future Medical Device Regulations

We have updated and simplified this guidance within our standard operating procedures. We have clarified the guidance on how to determine whether an RDS tool is a medical device, and have provided an interactive powerpoint slideset to steer you through the process.

Guide to six stages of RDS toolkit development

We have developed a guide to support editors and toolkit leads through the process of scoping, designing, delivering, quality assuring and implementing a new RDS toolkit. We hope this will help in project planning and in building shared understanding of responsibilities throughout the full development process. The guide emphasises that the project does not end with launch of the new toolkit. Implementation, communication and evaluation are ongoing activities throughout the lifetime of the toolkit.

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

Thursday 5 September 1-2 pm
Wednesday 24 September 4-5 pm
Friday 27 September 12-1 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.)

7 Evaluation projects

Dr Stephen Biggart from NHS Lothian has kindly shared with us the results of a recent survey of use of the Edinburgh Royal Infirmary of Edinburgh Anaesthesia toolkit. This shows that the majority of consultants are using it weekly or monthly, mainly to access clinical protocols, with a secondary purpose being education and training purposes. They tend to find information by navigating by specialty rather than keyword searching, and had some useful recommendations for future development, such as access to quick reference guidance.

We’d really appreciate you sharing any other local evaluations of RDS in this way – it all helps to build the evidence base for impact.

All Patients with suspected or proven endocarditis should be discussed with microbiology.

Synergistic (low dose) gentamicin is prescribed together with a penicillin or vancomycin in the initial treatment of native valve endocarditis due to enterococcal and streptococcal species and in prosthetic valve endocarditis of all aetiology including staphylococci.

Initial Dosing:

Calculate creatinine clearance (CrCl) via MDCalc (age, height, weight and serum creatinine required) and use the table to prescribe an initial dose of gentamicin.

Prescribing:

Prescribe on the regular section of the NHS Fife drug chart; do not use the treatment gentamicin prescribing, administration, monitoring form. Doses should be administered by IV bolus injection over 3-5 minutes.

Monitoring:

For synergistic gentamicin, both peak and trough levels are measured. The aim is to produce a peak (1 hour post dose) of 3-5mg/L and a trough (immediately before a dose) of <1mg/L.

Take the first sample one hour after the first dose (peak). Take the second sample immediately before the second dose (trough).

Record the exact time taken of all gentamicin samples in the clinical details section of the electronic request. Give the second gentamicin dose whilst awaiting levels unless concerns regarding renal function. Record sampling times and levels in the patient’s medical notes.

Interpretation of levels:

Monitor for toxicity:

Renal toxicity: Monitor creatinine daily. Signs of renal toxicity include an increase of creatinine or a decrease in urine output/oliguria
Ototoxicity: Suggested by any of the following – new tinnitus, dizziness, poor balance, hearing loss, oscillating vision, nausea or vomiting.
Stop treatment and seek advice if toxicity develops.
