Prescribing errors remain a significant cause of patient harm. Safe prescribing is not just about writing a prescription, but involves many cognitive and decision-making steps.
A set of national prescribing competencies for all prescribers (including non-medical) is needed to guide education and training curricula, assessment and credentialing of individual practitioners.
We have identified 12 core competencies for safe prescribing which embody the four stages of the prescribing process – information gathering, clinical decision making, communication, and monitoring and review.
These core competencies, along with their learning objectives and assessment methods, provide a useful starting point for teaching safe and effective prescribing.
With the expansion of prescribing rights to nonmedical prescribers, there is a need for an agreed set of national prescribing competencies for all prescribers.1-3 NPS MedicineWise has recently launched a framework which can be used to guide education curricula, assessment, continuing professional development and credentialing of individual practitioners.4 Our paper adds to this body of work.
What makes a good prescriber? Prescribing is often thought of as just the act of writing a prescription, but it is a high-risk intervention such that the privilege to prescribe should require demonstration of competence.5 It has been described as the process of deciding which medication to use and how to use it, while the prescription is the means by which these decisions are communicated.6 Safe prescribing must include cognitive and decision-making steps before the prescription is generated.6
A good prescriber is a safe one. Unfortunately, a systematic review of junior doctors' prescribing found that the range of errors was wide (2–514 of 1000 items prescribed and 4–82% of patients or charts reviewed).7
Education is one of the most effective methods to prevent medication errors.6,8,9 The World Health Organization Good Prescribing Guide was found to be useful in improving students' skills in multiple clinical settings.9 It could serve as a foundation for a targeted prescribing curriculum, although further development in both the teaching and assessment of prescribing is warranted.9 As an example, interactive case-based tutorials in therapeutic areas commonly associated with a high risk of patient harm were found to increase the ability of medical students to prescribe safely.10
Prescribing skills are usually learned during junior doctor training. For example, in general practice, registrars learn to prescribe mainly through their workplace experience.11
Prevention of medication errors can be improved through focused teaching and training. A set of principles have been developed to guide training of both undergraduates and postgraduates in the UK.8 These include:
A four stage model of prescribing has been developed (Fig. 1).12 This emphasises that prescribing is a staged process rather than a single event and is in line with UK prescribing competencies for new medical graduates.8 These stages are:
The prescriber should have the skills to gather the relevant patient information such as medical history, including current symptoms, current and recently ceased or changed medications, allergies, adverse drug reactions and diagnoses.
Prescribers should be able to make clinical decisions. This includes making or reviewing a diagnosis, using pharmacological knowledge to select which medicine to use along with appropriate dosing for the individual patient. The prescriber should also consider non-drug treatments, and engage the patient in collaborative decision making to improve adherence and patient outcomes.13
The prescriber should be able to tailor their decision-making styles, for example directive or collaborative, and decide which is most appropriate for the patient at that point in time,13 always valuing the patient's views14.
The prescriber should be able to convey the prescribing decision in a safe and effective manner to both the patient and to other health professionals involved. The prescription should be legible, unambiguous and without error-prone abbreviations for pharmacists to dispense and patients or nurses to administer. A management plan should be clear and contain triggers for referral or action. Both verbal and written communication skills are important. For example, the patient and their carer should be informed about why they have been prescribed a medication, how to use it and the expected duration of treatment. Monitoring requirements, potential adverse effects and contingency planning should also be discussed.
Electronic prescribing software with clinical decision support is now commonly used. Increasingly, electronic medicines management (including electronic inpatient medication charts) is being introduced. Along with the personally controlled electronic health record, these are powerful enablers of communication between prescribers, the healthcare team and the patient. Prescribers should become competent in using these tools.
The prescriber should be able to review the therapeutic or adverse effects of the treatment to inform dose adjustments or a change in treatment.
For ease of use in curriculum design, assessment, training and development, 12 core competencies were defined (Table). These were aligned against competencies from other organisations 15-20 and two underpinning elements were added:
For each core competency, learning objectives (criteria for meeting that competency) and how these are assessed have been outlined. Fig. 2 illustrates this using core competency four – assessing adherence to current and past medications and risk factors for non-adherence. These may be a useful adjunct to the Australian Curriculum Framework for Junior Doctors which currently does not set out criteria for assessing junior doctors' performance.20
Adult learning principles should be used in teaching the core competencies, including self-evaluation and observation by peers or a mentor with structured advice, such as the agenda-led outcome-based feedback.21 This method empowers the learner, reduces defensiveness, and allows an opportunity for change in behaviour. It identifies what help the learner wants and enables them to achieve learning goals by encouraging self-assessment.
The skills, attitudes and behaviours needed for prescribing could be shown and learned through simulated scenarios. Assessment should comprise a variety of methods so as to include the most appropriate format for any particular criterion.22 For example, to best evaluate whether a prescriber has acquired skills in detecting non-adherent behaviour (core competency four), the prescriber should be directly observed interacting with a patient.
This is in line with Miller's Pyramid23 which describes four levels for assessing clinical skills, competence and performance:
Achievement of level four is assessed through direct observation. To demonstrate prescribing competence, assessing at 'shows' and 'does' levels becomes important although it is more resource intensive and challenging to coordinate. Currently, direct observation of procedural skill is required in order to be deemed competent in surgical procedures. This should equally apply to prescribing.
Multiple source feedback such as peer assessment or 360° feedback can be used to ascertain if communication is clear to other clinicians and to patients and carers. Other means of assessing prescribing competency could include clinical audits of prescribing. These may be structured self audits such as those developed by NPS MedicineWise or targeted clinical audits coordinated within a healthcare facility. Timely feedback to prescribers to close the loop is essential.
A useful method for evaluating nurse prescribing combines practice-based observations with a structured competency checklist, analysis of written prescriptions and documentation of the prescribing episode in the medical record.24
Registrars have expressed difficulty in judging the quality of their own prescribing.11 The 12 core prescribing competencies and their accompanying criteria and assessments could serve as a formative tool for giving explicit feedback about the process and outcome of prescribing decisions. The competencies can also be used as a summative tool.
It has been recommended that qualification as a doctor, which includes a licence to prescribe, be contingent on passing an undergraduate prescribing examination. It has been suggested that clinicians should be reassessed to retain this privilege.25
A perennial tension exists between higher education providers (for example medical schools) and employers (for example health facilities) as to where responsibility lies in producing a graduate who is 'fit for purpose'. When a prescribing error occurs during the early weeks of internship, which party has failed? Closer collaboration between teaching and training graduates is clearly warranted. This could be facilitated by adopting a set of national prescribing competencies and agreeing to adopt set criteria and a framework for assessment. The benefits of standardised prescribing competencies may not otherwise be realised. The 12 core competencies and their accompanying methods of assessment provide a useful starting point for this work, although feasibility of the proposed assessment methods needs broader discussion.
