Background.
Statistical methods form the basis for clinical decision-making in evidence-based anesthesia.
Data on the knowledge of anesthesiologists about statistics are lacking.
This pilot study aims to provide a first impression of the anesthesiologists’ understanding of commonly used concepts in statistics.
Methods.
A cross-sectional pilot survey was performed at a major international anesthesia conference.
The questionnaire consisted of three basic multiple-choice questions on the topics “p value,” “confidence interval,” and “correlation.” Results of the questions are reported as percentage of correct answers (95% confidence interval).
Results.
65 questionnaires were analyzed.
Forty participants were male, and mean age was 40 (standard deviation: 10) years.
The question addressing the p value was correctly answered by 15% (95% CI: 8 to 27%) of respondents.
The question concerning the 95% confidence interval was answered correctly by 28% (95% CI: 18 to 40%) of participants.
For the question about correlation, a correct answer was given by 52% (95% CI: 40 to 64%).
None of the participants answered all questions correctly, and 19 participants provided a wrong answer to all questions.
Conclusions.
Anesthesiologists seem to demonstrate a poor understanding of statistical key concepts.
Further studies are needed to address statistical knowledge gaps among anesthesiologists more comprehensively.
