Initial Approach to a Patient Presenting with Symptoms
The initial approach to any patient presenting with symptoms must begin with a rapid assessment to identify life-threatening conditions requiring immediate intervention, followed by a systematic evaluation of clinical and epidemiological features to guide diagnosis and management.
Immediate Assessment for Critical Conditions
The first priority is to identify patients who require urgent intervention:
- Assess for sepsis immediately in any patient with acute illness by asking "could this be sepsis?" and following established sepsis identification protocols 1
- Evaluate cardiopulmonary stability and provide support as needed, including supplemental oxygen for hypoxemic patients (oxygen saturation <94%) 1
- Identify red flags for serious illness that require immediate action or specialist referral 1
Systematic Clinical Evaluation
Once life-threatening conditions are ruled out or addressed, proceed with structured assessment:
History Taking
Obtain specific clinical features systematically 1:
- Onset and duration: When and how symptoms began (abrupt vs. gradual), duration of illness 1
- Symptom characteristics: Quality, frequency, intensity, and pattern of symptoms 1
- Associated symptoms: Fever, pain location and character, nausea, vomiting, altered mental status, volume depletion signs (thirst, decreased urination, lethargy) 1
- Functional impact: Ability to perform routine and desired activities of daily living 1
Epidemiological Risk Factors
Identify exposure risks and predisposing conditions 1:
- Recent travel to developing areas or areas with known disease transmission 1
- Occupational exposures (healthcare, food handling, day-care) 1
- Consumption of unsafe foods or water 1
- Contact with ill persons or animals 1
- Recent medications (antibiotics, antacids, anti-motility agents) 1
- Underlying conditions predisposing to infection or complications (immunosuppression, extremes of age, chronic diseases) 1
Physical Examination
Conduct targeted examination focusing on 1:
- Vital signs: Temperature, heart rate, blood pressure (including orthostatic changes), respiratory rate 1
- Volume status assessment: Mucous membrane moisture, skin turgor, jugular venous pulsations 1
- System-specific findings: Based on presenting complaint (e.g., abdominal tenderness, neurological deficits, cardiac findings) 1
- Weight and body mass index for baseline documentation 1
Remote vs. Face-to-Face Assessment
When initial contact is remote 1:
- Do not routinely prescribe based on remote assessment alone - if a patient is potentially ill enough to require antimicrobials or other treatment, arrange face-to-face evaluation 1
- Arrange urgent face-to-face assessment if symptoms suggest serious illness, rapid deterioration, or if adequate evaluation cannot be completed remotely 1
- Consider patient context: Lower threshold for in-person evaluation in patients with comorbidities, frailty, or social circumstances that increase risk of poor outcomes 1
Initial Diagnostic Testing
Based on presenting complaint, obtain appropriate initial tests 1:
- Laboratory evaluation: Complete blood count, electrolytes (including calcium and magnesium), renal function, glucose, relevant biomarkers based on suspected diagnosis 1
- Electrocardiogram: For cardiac symptoms or risk factors 1
- Imaging: Chest radiograph, other imaging as indicated by clinical presentation 1
- Results should be available within 60 minutes to guide second-step decision-making 1
Common Pitfalls to Avoid
Action bias in uncertain diagnoses: When diagnosis is unclear, physicians tend to favor testing and intervention over watchful waiting 2. However, not all unexplained symptoms require immediate workup - consider whether follow-up is more appropriate than extensive testing 2.
Dismissing patient and family concerns: Patients with medically unexplained symptoms often feel unheard 1. Take time to acknowledge symptoms are real, conduct thorough examination, and address fears even when diagnosis is uncertain 1.
Missing the therapeutic alliance: Building rapport during initial evaluation improves outcomes and adherence to recommendations 1. Emphasize collaboration and shared decision-making from the first encounter 1.
Disposition Decision
After initial evaluation 1:
- Refer to specialist if red flags present: suspected malignancy, neurological disease, recurrent infections, abnormal screening tests, or symptoms requiring specialized evaluation 1
- Initiate treatment and arrange follow-up for patients with clear diagnosis who can be managed in current setting 1
- Provide self-care guidance with explicit safety-netting instructions for patients whose symptoms can be managed at home, including when and how to seek further care 1
