Abstract
Background: An important principle in basic and clinical pharmacology is Pharmacokinetics. Medical and Allied Health students tend to use online resources such as YouTube among their learning resource.
Objectives: The aim of this study is to investigate whether YouTube videos on pharmacokinetics provide accurate and reliable information that can be used by medical and allied health students.
Methods: YouTube was searched between 1-15 November using the following search terms: “Pharmacokinetics”, “Drug absorption”, “Drug distribution”, “Drug metabolism”, “Drug elimination”, “drug biliary excretion”, and “Drug renal excretion”. Only videos in the English and those matching the inclusion criteria were included. For each video, the following data were collected: title, URL, duration, number of viewers, date uploaded, and viewership per day, like, dislike, number of comments, number of video sharing, and the uploader /creator. Using a standardized criteria comprising technical (such as clarity of image and voice, absence of background noises), content, authority and pedagogy1, three evaluators (with medical/pharmacology background) independently assessed the videos (maximum score= 15). Data were analyzed and the agreement between the evaluators was calculated using Cohen’s kappa analysis. The agreement between evaluators had an overall score in the range of 0.582-0.949.
Results: The search identified 1460 videos. Of these, only 48 (3.3%) fulfilled the inclusion criteria. Thirty (62.5%) videos were classified as educationally useful scoring 13.83±0.45 (mean±SD). The remaining 18 videos scored on average 6.48±1.64 (p=0.000). The useful videos had been created by pharmacologists/educators (83.3%, n=25), professors from two universities conducting sessions to their students (13.3%, n= 4) and private tutoring body (3.3%, n= 1). No correlation was found between video total score and number of like, dislike or viewership/day.
Conclusions: YouTube videos on pharmacokinetics and drug elimination showed a range of variability in regard to the contents of their educational usefulness. However, some videos on Pharmacokinetics in English are suitable for use by students and can be recommended by teachers. Medical and Health educators should be aware of the potential influence of YouTube videos may have on student’s understanding of pharmacokinetics and drug elimination.
