Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention (1): Regular prescribing feedback and targeted education of junior doctors by a clinical pharmacist, through three ten minute sessions per week for four weeks.
- These sessions were face-to-face with a clinical pharmacist, in a convenient ward space (eg meeting rooms), and were conducted as a group (3 interns, 1 registrar and the clinical pharmacist)
- One of the principle investigators collected data from the medication charts of the general medical wards, pertaining to the type and frequency of prescribing errors. This was discussed with the clinical pharmacist and the feedback/teaching sessions focussed on common prescribing errors seen on the wards, as well as dangerous prescribing errors recently identified.


Intervention (2): e-learning intervention whereby junior doctors completed the Australian National Prescribing Service’s (NPS) National Inpatient Medication Chart Training e-learning course.
- This e-learning course comprises 7 modules covering aspects of safe prescribing.
- The modules are estimated to take between 80-95 minutes to complete all together.
- E-learning intervention doctors were asked to complete the course between the end of the baseline data collection period and the start of the intervention data collection (over the weekend) and to show the investigators the certificate of completion.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All junior doctors who were rotated onto general medicine at the time of the study participated, consisting of 12 interns and four registrars. The unit each doctor was assigned to was pre-determined by the hospital as part of the usual junior doctor rotations.

All units were made aware of the study before it began, and doctors were informed that they were expected to participate as part of an ongoing quality assurance process. Consultants were not involved in the study. Each unit was randomised to an intervention, as described below.

Allocation was not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The four general medical units were randomised to two intervention groups (one unit each) and control groups (two units) using a random number generator and a pre-defined sequence of allocation. Each medical unit was known by its number (medical unit 1, medical unit 2, medical unit 3 and medical unit 4). We pre-defined a sequence of allocation of unit to intervention group as (in order) Intervention one, intervention two, control unit 1 and control unit 2. Using a random number generator to provide numbers between 1 and 4, we allocated the first intervention to the unit corresponding to the first number produced, the second unit to the second number produced, etc.

Statistical methods / analysis
Statistical analysis was undertaken by chi-squared comparison of prescribing error rate for each group prior to, and following the intervention.

Our study objectives related to number of medication errors recorded rather than participant numbers. Based on a two-sided alpha value of 0.05 and 80% power to detect a 20% difference in error rate between the two periods (pre-intervention vs post-intervention: 40% vs 32%), we estimated that 589 medication orders were required per study group (a total of 1767). It was elected to collect data for longer than this number required due to the continuous nature of the pharmacist educational intervention.
