Educational assessment of the major lower limb amputations videos on YouTube.

OBJECTIVE

Videos of surgical procedures are viewed by some as potential training resources for surgeons and residents. However, there is little evidence on the effectiveness of surgical videos on learning and understanding complex three-dimensional surgical procedures. Lower extremity amputation is a complex surgery, and many residents and surgeons have low exposure to this type of procedures. This paper investigates the educational quality of lower extremity amputation videos posted on YouTube.

METHODS

The search was limited to the first 100 videos. Full-length videos of any major lower limb amputation or disarticulation were included. Key basic video data such as title, YouTube address (http://), country of origin, channel source, uploading date, video duration time, number of views, number of up-voters and number of down-voters were collected. An educational assessment tool has been developed specifically for limb amputations. It consists in 11 items: three general and eight amputation-specific, each having a maximum score of 2.

RESULTS

In total, 13 videos met the inclusion criteria for final analysis. Four videos reported the surgical technique of above knee amputation, two reported that of knee disarticulation and the remaining seven videos described below knee amputation. The average score (±SD) was 12.77 ± 5.2 yielding an average grade close to "Fair." A high level of concordance was found between the two assessors ( = 0.79). No correlation was found between educational assessment tool score and the pre-set variables (r = 0.6, R = 35.4%, F = 1.09,  = 0.4).

CONCLUSIONS

Most videos describing lower extremity amputation techniques were found to be of low-to-moderate quality. Only 4 out of 13 (30.7%) had an excellent educational and technical quality. Surgeons and surgical residents should be aware that not all posted videos on YouTube are beneficial. High educational quality videos are needed since many surgeons and residents have a low exposure to such surgeries.
