FLS skill retention (learning) in first year surgery residents.
BACKGROUND
Fundamentals of Laparoscopic Surgery (FLS) certification is reliable and valid; the American Board of Surgery requires FLS certification. Dynamics of skill retention after FLS training effect training schedules for residents. We hypothesized that the initial elevation of performance levels after FLS training would deteriorate predictably with time.


METHODS
FLS performance data on 16 new surgical residents (R01s) was examined retrospectively. These R01s trained at 16 weekly sessions. Training included 4 FLS tasks, VR simulator tasks, and open surgical skills. FLS skills were practiced weekly with feedback but no instruction. Performance was tested PRE, POST, and DELAY. Outcome metrics were task completion times (TCTs).


RESULTS
POST TCTs were below PRE TCTs in all R01s for all FLS tasks (P < 0.05). No difference was seen between the DELAY TCT and POST TCT for peg transfer (P = 0.726) and pattern cut (P = 0.114). The DELAY TCTs were longer than POST TCTs for extra- and intra corporeal knot-tying (P < 0.0001 and P = 0.029). Relative retention was 103% for peg transfer, 85% for pattern cut, 47% for extracorporeal knot tying, and 59% for intracorporeal knot tying. However, many individual's displayed DELAY TCT equal to or lower than POST TCT implying full retention.


CONCLUSIONS
This study extends the data on FLS skill retention to an actual "production" training curriculum. This FLS training provided effective learning in R01s. Although performance levels fell across these tasks on average and for the majority of individual R01s, significant skill retention remained at 7-8 months. Early training will enable R01s to maintain or elevate skill levels with additional training sessions.
