Abstract
Background: Prescription and administration of oxygen in emergencies by healthcare providers are
reported to be inappropriate in most settings. There is a huge gap in the knowledge of health
care providers on various aspects of oxygen therapy, and this may be a barrier to optimal
oxygen administration. Hence, it is essential to ascertain providers’ knowledge of acute oxygen
therapy so that appropriate educational interventions are instituted for better delivery.
There is no available validated instrument to assess knowledge of acute oxygen therapy.
The study aimed to develop, validate and evaluate the test-retest reliability of a questionnaire
to determine the doctors and nurses understanding of acute oxygen therapy.
Methods: This study involved the development of the questionnaire contents by a literature review,
assessment of face validity (n = 5), content validity, using a panel of experts (n = 10), item
analysis and test-retest reliability among a sample (n = 121) of doctors and nurses.
Results: Face validity indicated that the questionnaire was quick to complete (10–15 min), most
items were easy to follow and comprehensible. The global content validity index (S-CVI)
was 0.85. The test-retest reliability statistics showed a kappa coefficient of 0.546–0.897 (all
P<0.001) and percentage agreement of 80–98.3% indicating high temporal stability in the
target population. In total, 90% of the items fulfilled the reliability acceptance criteria. Item
discrimination analysis showed that most questions were at an acceptable level. The final
questionnaire included 37 item questions and eight sections.
Conclusion: The designed questionnaire is a reliable and valid tool for assessing knowledge of acute
oxygen therapy among doctors and nurses.
