Abstract
Background and Aims
Regional anaesthesia techniques are a part of perioperative medicine that affects both perioperative and long-term outcomes. We have a paucity of the data on the usage and practices of plexus and peripheral nerve blocks (PNBs). To the best of our knowledge, this is the first effort to validate a survey for plexus and PNBs. Subsequently, this questionnaire could be used for the survey to look for the trends and disparities in PNB practices and further to develop a national registry in the future.
Methods
Thirty questions were prepared after evidence-based search and reviewed by experts for suggestions. Changes were done and the questionnaire with the grading sheet was sent to 19 experts. The responses were analysed to calculate the content validity index (CVI) item-wise (I-CVI), scale-wise (S-CVI), and modified kappa statistics. The I-CVI of 0.78 and an S-CVI/average of 0.90 was taken as acceptable with more than six experts.
Results
Fourteen experts out of 19 assessed and graded the questions as per the provided sheet and submitted suggestions through the mail. Question reframing, option reconsideration, and change from single to multiple choices were incorporated as per the suggestions of the experts. Mean I-CVI for relevance, simplicity, clarity, and ambiguity was 0.99, 0.98, 0.98, and 0.99, respectively. S-CVI/average was 0.98, 0.97, 0.98, and 0.99 for relevance, simplicity, clarity, and ambiguity, respectively.
Conclusion
We conclude that this questionnaire has met the content validity criteria and can be used to study plexus and PNBs practices.
