Acute Assessment & Clinical Decisions
Recognise instability, build a prioritised problem list and turn clinical findings into a safe initial plan.
Quick revision ↓ Medical Dictionary
01Assess before labelling
An acutely unwell adult needs an immediate airway, breathing, circulation, disability and exposure assessment. Call for help early and treat life-threatening problems as they are found, with monitoring and repeated reassessment. A complete history should not delay resuscitation. Record respiratory rate, oxygen saturation, pulse, blood pressure, temperature, consciousness and bedside glucose, interpreting values in context rather than assuming one reassuring measurement excludes deterioration.
02Build a problem representation
Summarise the patient's age, relevant background, time course and defining findings in one sentence. A sudden painful swollen leg after immobility suggests a different problem from months of symmetrical ankle swelling. List the dangerous possibilities as well as the most likely diagnosis. Revise the list as information arrives; premature closure occurs when an early explanation prevents recognition of contradictory evidence or a second simultaneous illness.
03Choose useful investigations
Ask which decision each investigation could change. ECG and glucose may be immediately useful in collapse, while indiscriminate panels can create incidental abnormalities without resolving the urgent question. Consider timing, pretest probability and limitations. A result outside the reference range is not automatically the cause of illness; conversely, an early normal result may need repetition when the suspected process evolves over time.
04Plan treatment and reassessment
State the working diagnosis, immediate threats, supportive care, disease-specific steps and who will review the patient. Consider allergies, existing medicines, kidney function and treatment ceilings. Fluids, oxygen and analgesia require indications and monitoring rather than automatic administration. Record what response is expected and when to escalate if it does not occur. A plan without a review point can miss treatment failure or emerging harm.
05Communicate the clinical story
Use a structured handover that includes the reason for concern, relevant background, current findings and a clear request. Explain uncertainty to the patient without losing the immediate priorities. Document who was contacted and the agreed actions. Before discharge, ensure stability, practical support, responsibility for pending results and clear return precautions. An improvement in one symptom alone does not establish that discharge is safe.
High-Yield Revision
- Treat immediate threats while gathering the history.
- Interpret trends and the whole patient, not one number.
- Every initial plan needs a reassessment and escalation point.
Common Pitfalls
- Do not allow a diagnostic label to hide contradictory findings.
- Do not discharge without a plan for pending results and deterioration.
