Synopsis
Translate a clinical assessment into an accurate prescription that has a justified indication, practical administration instructions and an owned review plan.
- Confirm the person, therapeutic objective, medicine exposure and allergy history before selecting a treatment.
- An apparently usual dose can be unsafe after dehydration, renal deterioration, weight loss or an interacting prescription.
- Write the medicine, formulation, route, dose, frequency, indication and intended duration so the administrator need not infer them.
Reasoning priorities
Establish whose prescription is being written and what exposure already exists.
Use reliable identifiers and ask about prescribed, purchased, borrowed and recently stopped products. Record the active ingredient in combination remedies. An electronic repeat list shows intended prescribing, while the interview reveals administration; discrepancies require resolution rather than choosing whichever account is easiest to copy.
Worked reasoning
A 76-year-old with three days of vomiting, reduced urine output and a painful wrist requests repeat oral ibuprofen. She takes ramipril and a diuretic, has not checked her blood pressure and cannot recall her last kidney result.
- Identify the immediate problem: dehydration and reduced urine output could represent acute kidney injury. Ask about collapse, confusion, severe pain, trauma and systemic illness, and arrange prompt face-to-face assessment rather than treating the request as a routine repeat transaction.
- Reconstruct the medicine exposure, including the last ibuprofen dose and any purchased analgesics. The interaction risk comes from the combination of impaired perfusion, altered renal autoregulation and an NSAID; an old normal kidney result cannot establish present safety.
- Decide against authorising ibuprofen at this assessment. Evaluate the wrist and hydration, obtain relevant observations and renal tests, and arrange an alternative pain plan. Review the other medicines individually in the context of the acute illness, documenting any temporary withholding and criteria for restarting.
- Explain the decision in terms of the current illness and treatment goal. Provide a written record of exactly which medicines are being changed, whom to contact if intake or urine output worsens and when the pain and hydration will be reassessed.
- Verify closure: establish who will review the blood results and confirm that the prescription system reflects the plan. At follow-up, reassess pain, renal recovery and the continuing indication before any restart; a temporary hold must not disappear into an indefinite omission.
