Abstract

Introduction This study was conducted to describe the ability to comprehend basic epidemiologic and statistical concepts among doctors in selected hospitals in the Western Province.

Methodology A cross-sectional descriptive study was conducted during January to February, 2008. The study population consisted of 315 doctors - 43 (13.7%) specialists, 50 (16%) postgraduate trainees (PG) and 222 (70.3%) grade medical officers. A self administered questionnaire was used to assess perceived knowledge on selected epidemiologic and statistical concepts/parameters and two problem based questions which tested the ability to apply knowledge were used. Data were analyzed calculating the proportion who perceived to have good knowledge regarding each concept. Logistic regression was applied to test for differences in good knowledge between different groups of subjects.

Results More than 75% of the respondents claimed to have good knowledge on prevalence, sensitivity, specificity and case control studies. Less than 50% of them had good knowledge on risk difference, number needed to treat, systematic reviews, meta-analysis, p-value and 95% confidence intervals. Male doctors had a significantly higher good knowledge than female doctors (p<0.001), and those who read medical journals regularly than those who did not (p<0.05). Specialists and PG trainees had a significantly higher good knowledge (p<0.001) than grade medical officers. Correct answers of the respondents to the two problem based questions were 25% (n=79) and 15.8% (n=50), respectively.

Conclusion Even though some doctors claimed to have a good knowledge with regard to selected epidemiologic and statistical concepts, their ability to apply their knowledge was poor.
