Assessing prescribing competence

Prescribing of medicines is the key clinical activity in the working life of most doctors. In recent years, a broad consensus regarding the necessary competencies has been achieved. Each of these is a complex mix of knowledge, judgement and skills. Surveys of those on the threshold of their medical careers have revealed widespread lack of confidence in writing prescriptions. A valid and reliable assessment of prescribing competence, separate from an overall assessment of medical knowledge and skill, would have many benefits for clinical governance and patient safety, and would provide a measure of the success of training programmes in therapeutics. Delivering such an assessment presents many challenges, not least of which are the difficulty in identifying a surrogate marker for competent prescribing in clinical practice and the challenge of ensuring that competence assessed in a controlled environment predicts performance in clinical practice. This review makes the case for an on‐line OSCE as the most valid form of assessment and sets out the requirements for its development, scope, composition and delivery. It describes an on‐going attempt to develop a national assessment of prescribing skills towards the end of undergraduate medical training in the UK.
