Patient Assessment and Clinical Decision-Making
Structured assessment
Advanced assessment builds on a primary survey (catastrophic threats first) and a secondary survey (history, focused examination, vital signs, monitoring). The exam rewards a disciplined sequence: identify and treat immediate threats, then gather the information that changes your plan. Know the components of a focused history - presenting complaint, onset, provocation, quality, radiation, severity, time, associated features, and relevant past history and medications.
Concepts to master
- Primary versus secondary findings: a finding in the primary survey changes management immediately; the same finding in the secondary survey may only refine it.
- Baseline and trend: a single set of observations is weaker than a trend; deterioration is often a change, not an absolute value.
- Differential reasoning: generate plausible causes, then use findings to include or exclude; avoid anchoring on the first impression.
- Red flags: findings that mandate escalation, rapid transport or a specific CPG regardless of how well the patient looks.
- Reassessment: after every intervention, reassess the relevant parameters and document the response.
Traps
Common traps include a reassuring single observation masking a deteriorating trend; a distracting injury drawing attention from an airway or breathing threat; and a history that sounds benign but contains a red flag (e.g. syncope, exertional onset, anticoagulant use). Questions may also test whether you reassess after an intervention - the answer that omits reassessment is usually wrong.
Rule of thumb
Treat the patient, not the number - but never ignore a number that is trending the wrong way. Use the sequence: threat → history → focused exam → vitals → decision → intervention → reassess → document.
Worked example
A patient reports chest discomfort but looks comfortable with normal initial observations. The history reveals exertional onset and radiation. The correct reasoning treats the history as a red flag, prompts a full assessment and appropriate CPG entry, and does not let the normal first set of observations close the case.
