5. Results
4. Method
Medication errors are an important cause of harm to patients.1,2 Prescribing in
paediatrics brings extra challenges with dosing regimes based on age, weight and
surface area requiring complex calculations; small errors could have significant
consequences.2,3,4 Incidence of paediatric prescribing errors may be 0.15-13.2%.1,3,4
Problems we identified
•Age range: 3 days – 17 years
•Ward: Surgical 24, Neurology 10, Infectious Diseases 33, General 16
•Specialty: 59 medicine
24 surgery
•Audit proforma designed and
piloted over one day

Previous Audit
There is increasing recognition that the inappropriate prescription of antibiotics can
lead to adverse events, unnecessary cost, hospital acquired infections and antibiotic
resistance.5 Antibiotic stewardship aims to address this.5 In one study, antimicrobials
were the most common medication involved in paediatric medication errors.2
•Total 83 drug charts
•Sex: 44 male
39 female
•Background research and
consultation with colleagues to
identify key areas for audit
•Day of admission: day 1: 40, days 2-7: 37, days 8-150: 7
•Audited over 7 days including the
weekend: 10-16th February 2011

The GMC states that graduate doctors should ‘prescribe safely, effectively’, ‘calculate
appropriate drug doses’ and ‘provide a safe and legal prescription’ (page 23).6 Local
hospital policy gives clear guidance on writing safe prescriptions and the prescription of
antibiotics.7,8 Having reviewed previous local audit results,9 we audited the paediatric
inpatient department in a London teaching hospital to assess whether prescriptions
adhered to hospital policy for safe written prescriptions and antibiotic prescribing.

2. Objectives
 Investigate the incidence of prescribing errors
 Identify specific areas in which these errors occur
 Compare with previous local audit results
6. Discussion and Evaluation
 Identify key areas for improvement
 Educational interventions to stimulate change
Results showed some areas of success and others needing improvement. Patient details were
completed correctly in 91-100% of prescriptions. Whilst just below the target, this was well above the
78% result from a previous local audit.9 Weight was recorded on 96% of charts; this is essential for
safe dose calculation in paediatrics.

3. Standards
Our hospital Medicines Management Policy gives guidance on what constitutes a
safe written prescription to enable ‘safe, effective and efficient use of medicines’.7
We chose a 100% standard to audit the completion of these mandatory details.
Our hospital Antimicrobial Prescribing Policy states that an ‘intended duration and
indication should be indicated on the medicine chart’.8 The hospital regularly audits
this using a 70% standard, which we adopted. We also used this standard to audit
the documentation of dose calculations for antibiotics i.e. dose in mg/kg, which is
recommended by the local lead paediatric pharmacist.
Prescriptions must include:
• Name
• DOB/age
• Ward/department
• Hospital number
• Known sensitivities
• Consultant
• Weight (if <16 years)
Safe prescriptions:
•Write legibly, ball point
•Careful use of decimals
•Acceptable abbreviations:
micrograms, mg, g
mcg
mL, ml
cc, cm3
Units
U or IU
tabs
“ii”
•Prescribe strength not volume
•Document allergy status
100% standard
for patient details
and safe written
prescriptions
70% standard for
documenting
antibiotic dose
calculation,
indication and
duration.

We were below target on the technical writing of safe prescriptions. Only 59% of prescriptions
were written in capitals. Whilst not mandatory, this is good practice for ensuring legibility. Most
prescriptions (96%) were signed by doctors. Only 76% had been double signed by pharmacists. This
highlighted that the safety net provided by pharmacists cannot always be relied upon, particularly out
of hours. There were 14 instances of medicines being prescribed in volume, not weight. Dangerous
abbreviations were used in 6 charts including ‘U’ for the prescription of insulin units and ‘mcg’ for
micrograms. Widespread use of the abbreviation ‘U’ was found in a previous hospital-wide audit.9
Key messages:
Complete all sections of the drug chart fully
Prescribe clearly, in capitals
Avoid dangerous abbreviations
Document allergy status, with details
For all antibiotic prescriptions:
document dose in mg/kg, indication and duration
A previous audit in the paediatrics department found that only 67% of charts had allergy status
complete.9 Our results show that this practice has improved greatly to 92%, slightly below the 100%
target. However, of those allergies documented, clinical details were only provided for 8/14 e.g.
‘Penicillin – facial rash’. This is important clinical information which may influence drug choice.
Educational Presentations:
Presentation to new paediatric SHO/SpR doctors
Paediatric Surgical Audit Meeting
Paediatric Clinical Governance Meeting
These key findings informed our interventions (see box 7). Our audit had strengths and weaknesses:
Dissemination of key messages to:
All shared care specialties: Orthopaedics,
ENT, Haematology, Neurosurgery
Lead divisional Pharmacist
Lead Paediatric Nurse
The worst area of performance was antibiotic prescription. Documentation of dose calculation
mg/kg (50%), indication (33%) and duration (25%) were all well below the target of 70%. This was
also below the levels achieved in recent hospital audits.9
Support of doctors, nurses, pharmacists
Large number of patients, n=83
7 day period (weekends included)
Wide variety of data collected
Shows we are doing well in some areas
Highlights key areas for improvement
Educational intervention for new doctors
Confounding factors: no blinding, auditors
involved in prescribing
Variable timing of data collection
No data collected on the actual drugs and
doses prescribed
Cohort of doctors have rotated so cannot be
re-audited to assess effect of interventions
