Medicines in Clinical Practice
Foundations of safe prescribing and medicines responsibility
Applied learning on foundations of safe prescribing and medicines responsibility.
Learning objectives
• Explain why prescribing is a clinical process rather than a signature or electronic transaction. • Identify the minimum information needed before proposing or continuing treatment. • Distinguish individual professional accountability from multidisciplinary support. • Use a structured approach when information is incomplete, uncertain or conflicting. • Recognise when not prescribing, delaying prescribing or reviewing an existing medicine is the safer decision.
Overview
Learning objectives
- Explain why prescribing is a clinical process rather than a signature or electronic transaction.
- Identify the minimum information needed before proposing or continuing treatment.
- Distinguish individual professional accountability from multidisciplinary support.
- Use a structured approach when information is incomplete, uncertain or conflicting.
- Recognise when not prescribing, delaying prescribing or reviewing an existing medicine is the safer decision.
Prescribing is a longitudinal responsibility
A medicine decision begins before a prescription is written and continues after it has been supplied. Safe practice includes establishing the indication, confirming relevant history, checking interactions and contraindications, explaining benefits and harms, agreeing the plan with the patient, arranging monitoring, reviewing response and stopping treatment when it is no longer appropriate. A technically correct prescription can still be unsafe if the clinical reasoning around it is weak.
Adequate knowledge of the patient
Current GMC prescribing guidance requires clinicians to have adequate knowledge of the patient and to be satisfied that proposed treatment meets the patient’s needs. The amount of information required depends on the decision. Starting a high-risk medicine after an acute deterioration demands more information than continuing a stable low-risk medicine, but repeat prescribing must not become an automatic administrative act. Relevant information may include diagnosis, current symptoms, recent observations or examination, renal and hepatic function, allergies and previous adverse reactions, pregnancy potential where relevant, current medicines including non-prescription products, adherence, recent changes and the patient’s priorities.
Indication, goals and proportionality
Every medicine should have a current purpose. The question is not only ‘Is there an evidence-based indication?’ but also ‘Does this medicine make sense for this patient now?’ Benefit can be reduced by limited life expectancy, competing morbidity, treatment burden, poor adherence, intolerable adverse effects or a change in the patient’s goals. Conversely, stopping a medicine simply because the list is long can cause harm. Good prescribing is therefore proportionate rather than maximal or minimalist.
Responsibility in team-based care
Pharmacists, nurses and specialist teams improve prescribing safety, but their involvement does not erase the responsibility of the clinician who makes or signs the prescribing decision. A recommendation from another clinician should be considered in context: is the indication clear, is the medicine appropriate for this patient, are monitoring arrangements in place, and is responsibility for follow-up understood? Good systems distribute tasks; they do not make accountability disappear.
When information is incomplete
Incomplete information is common during urgent care, out-of-hours work and transitions. The safe response is not automatically to prescribe or refuse. First define what decision is genuinely urgent, identify the missing information that could change that decision, use reliable sources to verify it, and choose the least hazardous interim plan. Sometimes a short supply, temporary hold, enhanced monitoring, pharmacy discussion or prompt review is safer than either a full continuation or abrupt cessation. The reasoning and follow-up plan should be documented.
Electronic systems and clinical judgement
Electronic prescribing systems can reduce some errors, but alerts are imperfect. Alert fatigue, incomplete medicines lists, duplicated records, default doses and copied-forward instructions can all create new risks. A computer warning should be interpreted rather than blindly overridden or obeyed. Likewise, absence of an alert is not evidence that a prescription is safe.

Practical decision framework
A useful sequence is: What is the problem? What is the medicine intended to achieve? What do I know about this patient today? What could make the medicine unsafe or ineffective? What alternatives exist? What does the patient understand and prefer? What monitoring or review is required? Who owns the next action? If any of these questions cannot be answered, the gap itself becomes part of the clinical decision.
