Study design and population
This was a prospective interventional study that was conducted at the outpatient pediatric clinics at a university teaching hospital in Saudi Arabia. The study included only parents, aged 20 years or older, and who are fluent Arabic (native language) as the primary language of the studied educational tools. Participants were selected by convenient sampling while visiting the pediatric clinics, and each subject was randomly assigned to either conventional arm group or video-guided group. Subjects who were approached in weeks 1, 2, 7, and 8 of the study and were allocated to the conventional arm group, while the subjects involved in the second video-based arm group were approached in the other period (weeks 3-6). Noteworthy, none of them were scheduled to have LP on them or their siblings.
The conventional arm was the verbal explanation (Appendix I) that is being given on a routine basis for parents of children undergoing LP in the pediatric emergency department. In contrast, in the second video-based arm group, we utilized a standardized video on this group that contains the same information as the conventional arm, with streaming of graphic depictions (https://www.youtube.com/watch?v=Q2gm_iL5ZQE&t=95s or the shortcut: https://bit.ly/2mG12q0 ).
The verbal and video-recorded information were standardized as per the multiprofessional discussions between the pediatric intensive care (PICU), the pediatric infectious disease (PID), the pediatric neurology, and the pediatric emergency department (ED) teams within our institution.
