The aim of this study was to compare four methods for assessing the preferences of the dental profession for topics to be considered for the development of clinical practice guidelines.
The methods were: (1) a survey among dentists, (2) an analysis of topics discussed in dental peer groups, and (3) screening of dental journals. A fourth method was obtained from method number 3. The frequencies of the reported topics were calculated for each of the methods. For the fourth method, the number of publications per topic were plotted against the year of publication, and the slope of the linear regression line was used as an indicator. Within each of the four methods, the topics were ranked according to the frequency in which they were reported, and to the slope value. The reliability of the methods was tested by the "item-rest sum correlation", which is the correlation of the rank positions of one method with the sum of the rank positions obtained by the remaining three methods.
In using all methods, a total of 1027 topics were obtained. Reclassification resulted in 34 topics. Moderate item-rest sum correlations ranging from 0.34 to 0.48 were found for all methods, indicating that the rank order of every method moderately predicts the sum of the rank orders obtained by all other methods. The topic 'prevention of cross-infection' had the highest overall rank position.
It is concluded that the four applied methods appeared to provide a consistent ranking of potential topics. In view of the fact that the questionnaire method is generally applicable, this method should be preferred for assessing dentists' preferences for topics to be considered for the development of clinical practice guidelines.
本研究旨在比较四种评估牙科专业对临床实践指南制定中待考虑主题偏好的方法。
这些方法为：（1）对牙医进行调查，（2）分析牙科同行群体中讨论的主题，以及（3）筛选牙科期刊。第四种方法源自第三种方法。计算每种方法中报告主题的频率。对于第四种方法，将每个主题的出版物数量与出版年份作图，并将线性回归线的斜率用作指标。在这四种方法中的每一种内，根据主题被报告的频率和斜率值对主题进行排名。通过“项目-其余项目总和相关性”测试方法的可靠性，即一种方法的排名位置与其余三种方法获得的排名位置总和之间的相关性。
使用所有方法共获得1027个主题。重新分类后得到34个主题。所有方法的项目-其余项目总和相关性中等，范围为0.34至0.48，表明每种方法的排名顺序适度预测了所有其他方法获得的排名顺序总和。“预防交叉感染”主题的总体排名最高。
得出的结论是，所应用的四种方法似乎为潜在主题提供了一致的排名。鉴于问卷调查方法普遍适用，在评估牙医对临床实践指南制定中待考虑主题的偏好时应首选此方法。
