Background
Internists commonly perform invasive procedures, but serious deficiencies exist in procedure training during residency.
Objective
Evaluate a comprehensive, inpatient procedure service rotation (MPS) to improve Internal Medicine residents’ comfort and self-perceived
knowledge in performing lumbar puncture, abdominal paracentesis, thoracentesis, arthrocentesis, and central venous catheterization
(CVC).
Design
The MPS comprised 1 faculty physician and 1–3 residents rotating for 2 weeks. It incorporated lectures, a textbook, instructional
videos, supervised practice on mannequins, and inpatient procedures directly supervised by the faculty physician. We measured
MPS impact using pre- and post-MPS rotation surveys, and surveyed all residents at academic year-end.
Measurements and Main Results
Thirty-nine categorical Internal Medicine residents completed the required rotation and surveys over the 2004–2005 academic
year, performing 325 procedures. Post-MPS, the percentage of residents reporting comfort performing procedures rose 15–36%
(p < .05 except for arthrocentesis, and CVC via internal jugular and femoral veins). The fraction desiring more training fell
26–51% (all p < .05). After the MPS rotation, self-rated knowledge increased in all surveyed aspects of the procedures. The year-end survey
showed that improvements persisted. Comfort at year-end, for all procedures except abdominal paracentesis, was significantly
higher among residents who rotated through the MPS than among those who had not. Self-reported compliance with recommended
antiseptic measures was 75% for residents who completed the MPS, and 28% for those who had not (p < 0.001).
Conclusions
A comprehensive procedure service rotation of 2 weeks duration substantially improved residents’ comfort and self-perceived
knowledge in performing invasive procedures. These benefits persisted at least to the end of the academic year.
