Improving prescribing at the Royal Free Hospital

This document explains how a new drug chart improved antimicrobial stewardship at the Royal Free Hospital.

Summary

The spread of bacteria resistant to antibiotics is an important health threat. It means that antibiotics may no longer work when needed to treat infections.

Antibiotics are unlike other drugs used in medicine, as the more we use them the less effective they become.

The efficacy of antibiotics can be conserved through antimicrobial stewardship (AMS) programmes.

The aims of AMS initiatives are to:

  • improve the safety and quality of patient care
  • contribute significantly to reductions in the emergence and spread of antimicrobial resistance (AMR)

The Start Smart then Focus (SSTF) toolkit is designed to improve AMS in secondary care. It is a recommended resource for AMS included in NICE guidance on antimicrobial stewardship.

Royal Free Hospital: prescribing quality audit

An audit of antibiotic prescribing quality at Royal Free Hospital in February 2014 showed poor compliance to SSTF principles. For example, on drug charts, staff didn’t state clearly the indication and duration of antibiotics.

What was involved

In response to the audit, the Royal Free designed a specific antibiotic prescribing section for drug charts, and ran a pilot. This pilot tested if the chart improved how staff recorded indication and duration of antibiotics.

After a successful pilot, the trust drug chart was redesigned with a specific section for short term antibiotics.

This included a new section for 48 hour review, allowing prescribers to:

  • review whether the patient needs to stop or switch antibiotics
  • see what the antibiotic prescribing decision was

Marisa Lanzman, senior pharmacist, antimicrobials, Royal Free London NHS Foundation Trust, said:

The specific section on the drug chart for antibiotics has made short term antimicrobial prescriptions more prominent than on the previous chart.

The chart also limits prescriptions to a maximum of 7 days. The review section makes the choice of options at 48 hours clearer and allows prescribers to sign off their antibiotic prescribing decision.

The drug chart was launched at the Royal Free Hospital in August 2015 and an audit was carried out in September 2015 to look again at antibiotic prescribing quality.

Pilot outcomes

191 antibiotic prescriptions were reviewed over a 1 week period. 77% of prescriptions were prescribed on the correct section on the drug chart.

Improvements were seen in:

  • documentation on the drug chart of indication for antibiotic therapy (27% increased to 74%)

The pilot highlighted a need for further training and improvement in the documentation of:

  • duration on the drug chart (completion rate 47%)
  • the 48 hour review on the drug chart (completion rate 30%)

Previous audits have shown that documentation of the 48 hour review in the notes is 74%. This has not yet translated to documentation on the drug chart.

Compliance with antibiotic guidelines improved from 77% to 90%.

Prescribing Quality Criteria % compliance pre drug chart launch (point prevalence survey February 2015) % compliance post drug chart launch (September 2015)
Indication for antibiotics written on drug chart 27% 74%
Compliant with antibiotic guidelines or micro/ID advice 77% 90%
Duration or stop/review date on drug chart 35% 47%
Review section completed not available 30%

What works well

The Royal Free Hospital’s strengths in antimicrobial stewardship include:

  • high compliance with antibiotic guidelines, resulting in improved antibiotic prescribing practice
  • commitment to tackling antimicrobial resistance through antimicrobial stewardship
  • improvements in surveillance through keeping better prescribing records

What could be better

There has been a significant increase in documenting prescribing decisions at the Royal Free Hospital. The audit recommends:

  • indicating prescribing decisions on every prescription to help review prescriptions
  • engaging further with clinical staff to review antibiotics at 48 hours to consider switching to narrow spectrum antibiotics

Next steps

Marisa Lanzman, senior pharmacist, antimicrobials, Royal Free London NHS Foundation Trust said:

This audit in 2015 has shown that the new design of the drug chart has improved antimicrobial stewardship within the Royal Free Hospital and resulted in better prescribing behaviour.

The results of this audit were disseminated to the Antimicrobial Stewardship Committee and will be shared throughout the Trust.

They will continue to shape further initiatives within the hospital to improve antimicrobial stewardship and assist with training prior to implementation of the drug chart across other sites in the Trust.
