Use it or lose it: is de-skilling evidence-based?

Area of Science:

• Medical Education
• Procedural Skills Assessment
• Healthcare Quality Assurance

Background:

• The concept of 'de-skilling' suggests skill attrition due to infrequent practice.
• Current medical accreditation often mandates minimum annual procedure numbers for practitioners.
• The evidence supporting these minimums for maintaining procedural competence is largely anecdotal.

Purpose of the Study:

• To review the existing literature on evaluating procedural skill competence.
• To assess the relationship between procedure frequency and skill maintenance.
• To critically examine the basis for mandatory procedural minimums in medical practice.

Main Methods:

• Literature review methodology.
• Analysis of studies evaluating procedural skill competence.
• Synthesis of evidence regarding skill decay and procedural volume.

Main Results:

• Limited empirical evidence supports the direct link between infrequent practice and significant skill degradation in procedural medicine.
• The effectiveness and necessity of arbitrary minimum procedure counts for maintaining competence are questionable.
• Current accreditation requirements may not be optimally aligned with evidence-based competency assessment.

Conclusions:

• The assumption that a specific minimum number of procedures guarantees competence requires further rigorous investigation.
• Alternative or supplementary methods for assessing and ensuring procedural competence should be explored.
• Policy decisions regarding procedural practice requirements should be evidence-based rather than anecdotal.
