BACKGROUND: Video‑based teaching has become rapidly popular during the coronavirus disease
2019 (COVID‑19) pandemic. The current study aimed to assess the efficacy of a hybrid video‑based
teaching module of oxygen therapy and critical care troubleshooting in nursing professionals managing
COVID‑19 patients in our institute.
MATERIALS AND METHODS: A retrospective analytical study (pretest and posttest design) was
conducted in our medical education department in March 2022 using the data from a workshop
conducted on oxygen therapy and critical care area troubleshooting during COVID‑19 patient
management for 296 nursing professionals. A hybrid video‑based teaching module was used. Pretest
and posttest data were compared along with subgroup analysis. P value <0.05 was considered
RESULTS: Posttest scores were significantly higher than the baseline scores in the overall group
as well as in all subgroups (P < 0.001). Subgroup comparisons revealed no significant difference
in mean baseline pretest and posttest scores in male versus female participants. Baseline pretest
scores (P = 0.02) and posttest scores (P = 0.08) were lower in the nurses of the noncritical areas
compared to critical area nurses. Mean improvement in posttest score compared to baseline score
was similar between all groups.
CONCLUSION: Hybrid technique involving both video aspects and in‑person teacher presence
for demonstration or troubleshooting improves perceived knowledge in nursing professionals with
some prior formal training and may be superior to the conventional only didactic/lecture‑based
demonstrations, especially in the context of imparting rapid training during pandemics or similar
urgent situations.
