What are the steps to complete a mini CEX (Clinical Evaluation Exercise) for a patient?

Mini-CEX Implementation Steps

The mini-CEX should be conducted as a brief, focused clinical encounter lasting approximately 20-25 minutes, where a faculty member or senior resident directly observes a trainee performing a focused history and physical examination with a real patient, followed by immediate structured feedback lasting 5-8 minutes. 1, 2

Pre-Encounter Preparation

• Select an appropriate clinical setting - The mini-CEX can be performed in inpatient wards, outpatient clinics, emergency departments, or any location where actual patient encounters occur 1, 2
• Choose a suitable patient case - Select either new or follow-up patients presenting with diverse clinical problems that match the trainee's level and learning objectives 1, 3
• Brief the trainee - Inform the resident they will be observed conducting a focused (not complete) history and physical examination, and that immediate feedback will follow 1, 4
• Ensure documentation tools are ready - Have the mini-CEX evaluation form available with the 9-point rating scale for seven core competencies 1, 2

During the Clinical Encounter

• Observe the focused clinical interaction - The evaluator watches the trainee perform a targeted history and physical examination relevant to the patient's presenting problem, without interruption 1, 3
• Monitor specific competencies - Assess medical interviewing skills, physical examination technique, professionalism/humanistic qualities, clinical judgment, counseling skills, organization/efficiency, and overall clinical competence 1, 2
• Time the observation - The clinical observation portion should average 12-25 minutes, though this may vary based on case complexity 2, 3
• Request diagnostic formulation - After the patient encounter, ask the trainee to present their differential diagnosis and proposed treatment plan 1

Post-Encounter Assessment and Feedback

• Rate performance immediately - Score each of the seven competencies using the 9-point scale (1=unsatisfactory, 4-6=satisfactory, 7-9=superior) 1, 5
• Provide structured verbal feedback - Spend 5-8 minutes giving specific, actionable feedback on observed strengths and areas for improvement 2, 3
• Document the encounter - Complete the mini-CEX form including patient demographics, clinical setting, case complexity, time spent, and satisfaction ratings from both evaluator and trainee 1, 2
• Identify learning gaps - Use the assessment to pinpoint specific knowledge or skill deficiencies requiring remediation 3

Program Implementation Requirements

• Plan for multiple encounters per trainee - Each resident requires 7-9 mini-CEX evaluations throughout the rotation to achieve adequate reliability and reproducibility 2, 5
• Distribute evaluations across settings and evaluators - Collect assessments from different faculty members and residents in both inpatient and outpatient environments to capture diverse clinical scenarios 2
• Schedule strategically - Conduct mini-CEX sessions at regular intervals (e.g., one evaluation every 1-2 weeks) rather than clustering them 2
• Orient all evaluators - Train faculty and senior residents on the mini-CEX format, rating scale interpretation, and feedback techniques before implementation 2

Common Pitfalls to Avoid

• Do not confuse with traditional CEX - Unlike the traditional clinical evaluation exercise, the mini-CEX focuses on a brief, targeted encounter rather than a complete history and physical examination 1
• Avoid single evaluations - One mini-CEX provides insufficient data; the tool requires multiple observations (minimum 7) to achieve acceptable reliability 5
• Manage trainee anxiety - Residents initially perceive the mini-CEX as anxiety-provoking due to its assessment component, but this diminishes with repeated exposure 4
• Balance assessment and education - While the mini-CEX serves dual purposes, emphasize its educational value through high-quality feedback to reduce performance anxiety 4, 3
• Ensure timely feedback - Immediate post-encounter feedback is essential; delayed feedback significantly reduces the educational impact 1, 3

Quality Metrics

• Evaluator satisfaction - Faculty and resident evaluators typically rate satisfaction with the mini-CEX at 6-7 on a 9-point scale 2, 3
• Trainee satisfaction - Residents generally rate satisfaction higher (6.8-7.5) once they understand the format and receive constructive feedback 2, 3
• Internal consistency reliability - The mini-CEX demonstrates strong internal consistency (reliability coefficient 0.90) when multiple encounters are aggregated 5
• Validity evidence - Mini-CEX scores correlate significantly with corresponding sections of standard evaluation forms and in-training examination performance 5
