Brief summary

Title: Randomized prospective study comparing the effectiveness of spaced learning to mass learning in microsurgical procedures. Background: Spacing phenomenon occurs when learning outcomes are greater with the teaching process spread out over time (spaced learning), as opposed to having the same total duration of teaching carried out over a single session (mass learning). Spaced learning has been shown to improve explicit memory tasks including free recall, recognition, cued -recall and frequency estimation. It has been used in various medical specialties with promising results and has been shown to be at least as good as mass training in learning clinical skills such as cardio-pulmonary resuscitation and laparoscopy skills. We aim to test the concept of spaced learning in learning delicate and complex skilled procedures like microsurgery. Our hypothesis is that spaced learning is better than mass learning in acquiring microsurgical suturing skills. Methodology: Medical students with no prior exposure to microsurgical training were randomized into control (mass-learning) and treatment (spaced learning) groups. The students were all taught to handle microsurgical instruments and to suture a prefabricated 4mm wide elastic strip under the microscope using Digital Surgicals MicroTrainer. The control group was taught continuously over 8hrs while the treatment group was taught in 2-hour sessions held each week over a span of 4 weeks. The learning outcomes that were measured included duration taken as well as the placement of the sutures in relation to each other, with the latter being objectively assessed with the use of a computer program from Digital Surgicals. In addition to being assessed at the beginning of the sessions, all participants completed another test 1 month after the completion of the sessions.

Design outcomes

Primary

MeasureTime frameDescription
DurationFor the mass learning group, at the end of the 1-day teaching session; for the spaced learning group, at the end of 1 month of teaching sessions.Duration taken to place pre-determined number of sutures on elastic strip
Suture density and alignmentFor the mass learning group, at the end of the 1-day teaching session; for the spaced learning group, at the end of 1 month of teaching sessions.Another primary outcome measure is the objective scoring of the placement of sutures using a computer program from Digital Surgicals. In particular, the alignment and spacing of the sutures in relation to each other were assessed.

Secondary

MeasureTime frameDescription
Retention of skills - assessing duration1 month after the end of the final teaching sessionDuration taken to place pre-determined number of sutures on elastic strip - to assess retention of skills at 1 month after the completion of teaching sessions.
Retention of skills - assessing suture density and alignment1 month after the end of the final teaching sessionAssess retention of skills by assessing the suture density and alignment at 1 month after the completion of teaching sessions.
