Monitoring Trends and Escalation
Interpret serial results, recognise a concerning trajectory and define the action, ownership and follow-up needed.
How to prepare for the PSA
Combine patient-centred prescribing judgement with fast BNF navigation, reliable calculations, complete prescriptions and explicit monitoring and communication.
Core concepts
Concept 1
A trend can be more informative than one isolated value, particularly when baseline and timing are known.
Exam cue: Compare the current result with baseline, prior values and the expected direction of change.
Concept 2
Monitoring is incomplete unless the plan defines who reviews the result and what threshold triggers a prescribing decision.
Exam cue: Identify the threshold that changes treatment or urgency.
Concept 3
Unexpected deterioration, a narrow therapeutic margin or an unclear result may require urgent senior, pharmacy or specialist input.
Exam cue: Make ownership of review and escalation explicit.
Risk pitfalls and guardrails
Reassuring oneself with a result still inside a reference range despite a concerning trend.
Guardrail: Do not let a familiar medicine, reference search or calculator output replace patient-specific safety checks and escalation.
Ordering a test without a plan to review or act on it.
Guardrail: Do not let a familiar medicine, reference search or calculator output replace patient-specific safety checks and escalation.
Adjusting a high-risk medicine beyond current competence without advice.
Guardrail: Add an independent check of indication, dose, route, interaction, monitoring and practical administration.
Memory anchors
Trend
Interpret change over time alongside the absolute result.
Action Threshold
Define what result will trigger continuation, adjustment, withholding or escalation.
Ownership
Assign who will review the result and by when.
Unexpected Change
Reassess the patient and medicine when results move differently from expectation.
Escalate
Seek senior, pharmacy or specialist help when risk or uncertainty exceeds competence.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
