Optimal History-Taking Workflow for Emergency Medicine Residents
Use a chief complaint-driven, differential diagnosis-guided approach that prioritizes parallel progression and anticipatory actions while maintaining structured documentation of key elements.
Core Workflow Structure
The most effective history-taking approach for EM residents centers on starting with the chief complaint and immediately generating a differential diagnosis that directs all subsequent questioning 1. This method aligns with how expert clinicians develop diagnostic expertise through pattern recognition and illness scripts, rather than exhaustive systematic reviews.
Initial Patient Encounter
Take the initial history with the nurse present whenever possible—this practice is strongly associated with enhanced resident efficiency 2. This approach allows you to:
- Gather information simultaneously from multiple sources
- Clarify discrepancies in real-time
- Begin forming your differential immediately
- Initiate orders earlier in the patient encounter
The History-Taking Sequence
Structure your questioning around these elements, documented in this order:
- Chief complaint and onset (acute vs. chronic presentation)
- Pertinent positives and negatives specific to your differential diagnosis 1
- Red flag symptoms that change disposition or urgency
- Medication history and allergy status (commonly omitted but critical) 3
- Relevant past medical history (only what impacts current presentation)
- Social factors affecting disposition
Critical caveat: Avoid the medical school approach of comprehensive review of systems. Instead, ask targeted questions that distinguish between competing diagnoses on your differential 1, 4. The experienced physician knows which questions to ask and how to interpret the answers—this is what you're learning.
Efficiency-Enhancing Practices
Parallel Progression
Maintain an average patient load and work multiple patients simultaneously 2, 5. High-productivity physicians demonstrate:
- Cognitive offloading: Write orders and document findings immediately rather than holding information in working memory 5
- Anticipatory communication: Inform consultants, imaging, and nursing of likely needs before complete workup 5
- Selective resource utilization: Order only tests that will change management 5
Documentation Strategy
Use dictation or templated notes rather than typing whenever possible—this is associated with higher efficiency 2. Your documentation must include 6, 3:
- Responsible consultant name
- Complete medication list with doses
- Allergy status (explicit documentation, not assumed)
- Differential diagnosis (not just final diagnosis)
- Clinical reasoning for testing and disposition decisions
Common pitfall: 37% of interruptions occur during order entry, and 41.5% during charting 7. These are high-risk moments for errors. When interrupted during these tasks, use cognitive offloading strategies—write down where you were before addressing the interruption.
Managing Workflow Interruptions
Residents experience frequent interruptions (attending physicians are the most common source) 7. To mitigate risks:
- Return to your initial task after interruptions—residents fail to do this 17% of the time 7
- Advocate for yourself: Nearly 93% of residents don't stop inappropriate interruptions 7
- Minimize EMR review time: Excessive chart review is negatively associated with efficiency 2
Practical Implementation
High-Acuity Areas
Expect 6-8 more interruptions per shift than in low-acuity areas 7. Compensate by:
- Using structured proformas to prevent omissions 3
- Increasing frequency of cognitive offloading
- Setting clear communication expectations with team
Running the Board
Regularly "run the board" (review all active patients)—this practice correlates with higher efficiency 2. Use this time for:
- Anticipating next steps for each patient
- Identifying bottlenecks
- Communicating proactively with consultants and nursing
Time Allocation
Increase time spent on:
- Direct conversations with care team members (positively associated with efficiency) 2
- Dictation and smartphone text communication for rapid information transfer 2
Decrease time spent on:
- Repeated patient room visits (negatively associated with efficiency) 2
- Prolonged attending conversations during active patient care 2
The fundamental principle: Your history-taking should be a focused, hypothesis-driven process that enables rapid parallel progression through multiple patients while maintaining safety through structured documentation and cognitive offloading strategies. This approach teaches clinical expertise by forcing you to develop increasingly refined illness scripts and pattern recognition 1.
