Results

The content of the three reference websites (NYSORA, ACEP and USRA) were analyzed for completeness using the categories outlined in Column 1 of Table 1. NYSORA had the most complete instructional content, recording 100% of the categories for each of the seven blocks. ACEP and USRA achieved means of 93.5 and 95.2%, respectively, of categories discussed. The TAP block was omitted for statistical calculations for ACEP, as they did not provide any instructional content for this particular block. "Indications" was the category missed most by USRA, with five out of seven blocks missing this content, while ACEP did not discuss "catheter placement" in any of its instructional videos.

Column 2 of Table 1 demonstrates the percentage of the analyzed YouTube videos (35 total videos from 7 blocks and 5 videos each) which contained each of the 18 educational characteristics, that were established as a control from NYSORA, USRA and ACEP. The least included category in the YouTube videos was "references". Only 6 of the 35 (17.1%) videos evaluated by the research team referenced primary sources. "Guide for catheter placement" (40%) and "Atlas picture of anatomy" (48.6%) were the second and third least referenced categories included in all YouTube videos reviewed.

Table 2 compares and contrasts the differences in percentage of educational characteristics found in educational material between the 3 anesthesia societies (NYSORA, USRA and ACEP) compared to the YouTube videos. This is broken down by each of the individual 7 nerve blocks reviewed for this study. As is evident in the table, none of the reference material for the 7 blocks contains less than 94.4% of the educational categories in the anesthesia society reference material. Compare that to the YouTube videos, which range as low as 68.9% for the popliteal nerve block videos and no higher than 90.0% for the interscalene nerve block instructional videos. (Note: ACEP TAP block was omitted for statistical calculations, as they did not provide any instructional content for this particular block).

Overall, the regional anesthesia societies' websites offered very thorough instruction for each nerve block. Figure 1 compares the percentage of educational characteristics present in the traditional online sources (NYSORA, ACEP and USRA) to the average seen in the YouTube videos. As demonstrated herein, in each of the 18 educational characteristics examined, there was a higher percentage of societal reference educational material that contained the material than was present in the YouTube videos analyzed.

Finally, Figure 2 compares and contrasts the percentage of educational categories referenced in educational material by nerve block. For each of the seven nerve blocks, the educational material provided by NYSORA, ACEP and USRA contained higher percentages of the educational categories than the YouTube videos. Interestingly, the YouTube videos for the four brachial plexus blocks (interscalene, supraclavicular, infraclavicular and axillary) had a higher percentage of educational categories than other classes including lower extremity (femoral and popliteal) and TAP blocks.
