To determine whether there is a gap between what patients know about early-stage prostate cancer and what they need to know to make treatment decisions, and whether the information patients receive varies depending on their treating physician.
Needs assessment was performed using a questionnaire consisting of 41 statements about early-stage prostate cancer. Statements were divided into six thematic subsets. Participants used a 5-point Likert scale to rate statements in terms of knowledge of the information and importance to a treatment decision. Information gaps were defined as significant difference between the importance and knowledge of an item. Descriptive statistics were used to describe demographic subscale scores. The information gap was analyzed by a paired t test for each thematic subset. One-way analyses of variance were used to detect any differences on the basis of treating physician.
Questionnaires were distributed to 270 men (135 treated by radical prostatectomy, 135 by external beam radiotherapy). The return rate was 51% (138 questionnaires). A statistically significant information gap was found among all six thematic subsets, with five of the six P values less than 0.0001. Statistically significant variation was observed in the amount of information patients received from their treating physicians among four of the thematic subsets.
There is an information gap between what early-stage prostate cancer patients need to know and the information they receive. Additionally there is a difference in the amount of information provided by different physicians.
确定患者对早期前列腺癌的了解与他们做出治疗决策所需了解的内容之间是否存在差距，以及患者获得的信息是否因治疗医生而异。
使用一份由41条关于早期前列腺癌的陈述组成的问卷进行需求评估。陈述分为六个主题子集。参与者使用5点李克特量表根据对信息的了解程度和对治疗决策的重要性对陈述进行评分。信息差距定义为一个项目的重要性与了解程度之间的显著差异。描述性统计用于描述人口统计学子量表得分。通过对每个主题子集进行配对t检验来分析信息差距。使用单因素方差分析来检测基于治疗医生的任何差异。
向270名男性发放了问卷（135名接受根治性前列腺切除术，135名接受外照射放疗）。回收率为51%（138份问卷）。在所有六个主题子集中均发现了具有统计学意义的信息差距，六个P值中有五个小于0.0001。在四个主题子集中，观察到患者从治疗医生那里获得的信息量存在统计学上的显著差异。
早期前列腺癌患者需要了解的内容与他们获得的信息之间存在信息差距。此外，不同医生提供的信息量也存在差异。
