Biostatistics is well recognized as an essential tool in medical research, clinical decision making, and health management. Deficient basic biostatistical knowledge adversely affects research quality. Surveys on this issue are uncommon in the literature.
To study the use of biostatistics in research by teaching faculty and postgraduate students from colleges of modern medicine.
Cross-sectional study in colleges of modern medicine.
A pretested proforma was used to collect information about the use of biostatistics by teaching faculty and final-year postgraduate students from colleges of modern medicine. The study period was 6 months.
Chi-square test, Spearman rank correlation coefficient, and multivariate analysis were used for analysis of data.
With this questionnaire, the maximum possible score for appropriate use of biostatistics in research was 20. The range of scores obtained by the study subjects was 1-20 and the median was 11. Appropriate use of biostatistics was independent of sex, designation, and education (P>.05). Spearman coefficient showed low-but significant-correlation between the score and the number of papers presented and published (P=.002 and P=.000, respectively).
The study showed that nearly half of the respondents were not using statistics appropriately in their research. There was also lack of awareness about the need for applying statistical methods from the stage of planning itself.
生物统计学被公认为医学研究、临床决策和健康管理中的一项重要工具。基础生物统计学知识的欠缺会对研究质量产生不利影响。关于这一问题的调查在文献中并不常见。
研究现代医学院校教师和研究生在研究中对生物统计学的使用情况。
在现代医学院校进行横断面研究。
使用一份经过预测试的表格收集现代医学院校教师和最后一年研究生对生物统计学使用情况的信息。研究为期6个月。
采用卡方检验、Spearman等级相关系数和多变量分析对数据进行分析。
通过这份问卷,在研究中正确使用生物统计学的最高可能分数为20分。研究对象获得的分数范围为1至20分,中位数为11分。生物统计学的正确使用与性别、职称和学历无关(P>.05)。Spearman系数显示分数与发表和出版的论文数量之间存在低但显著的相关性(分别为P=.002和P=.000)。
该研究表明,近一半的受访者在其研究中未正确使用统计学方法。从研究计划阶段开始就缺乏对应用统计方法必要性的认识。
