Little is known about ICU physicians' self-confidence and knowledge related to palliative care. Our objective was to investigate self-confidence and knowledge of German ICU physicians related to palliative care, and to assess the impact of work experience, gender, specialty and additional certifications in pain or palliative medicine.
In a multicentre prospective observational study ICU physicians of ten hospitals were asked to rate their self-confidence and to complete a multiple choice questionnaire for the assessment of knowledge. Beyond descriptive statistics and non-parametric tests for group comparisons, linear regression analysis was used to assess the impact of independent variable on self-confidence and knowledge. Spearman's rank test was calculated.
55% of answers in the knowledge test were correct and more than half of the participants rated themselves as "rather confident" or "confident". Linear regression analysis revealed that an additional certificate in either pain or palliative medicine significantly increased both knowledge and self-confidence, but only 15 out of 137 participants had at least one of those certificates. Relation between self-confidence and the results of the knowledge test was weak (r = 0.270 in female) and very weak (r = -0.007 in male).
Although the questionnaire needs improvement according to the item analysis, it appears that, with respect to palliative care, ICU Physicians' self-confidence is not related to their knowledge. An additional certificate in either pain or palliative medicine was positively correlated to both self-confidence and knowledge. However, only a minority of the participants were qualified through such a certificate.
关于 ICU 医生在姑息治疗方面的自信和知识，我们知之甚少。我们的目的是调查德国 ICU 医生在姑息治疗方面的自信和知识，并评估工作经验、性别、专业和疼痛或姑息医学方面的额外认证对其的影响。
在一项多中心前瞻性观察研究中，我们要求十家医院的 ICU 医生评估他们的自信，并完成一份多项选择问卷，以评估他们的知识。除了描述性统计和组间比较的非参数检验外，我们还使用线性回归分析评估独立变量对自信和知识的影响。计算 Spearman 秩检验。
知识测试中 55%的答案是正确的，超过一半的参与者自我评估为“相当自信”或“自信”。线性回归分析显示，在疼痛或姑息医学方面的额外证书显著提高了知识和自信，但在 137 名参与者中只有 15 人拥有其中一个证书。自信与知识测试结果之间的关系较弱（女性为 r=0.270），非常弱（男性为 r=-0.007）。
尽管根据项目分析，问卷需要改进，但似乎 ICU 医生在姑息治疗方面的自信与知识无关。在疼痛或姑息医学方面的额外证书与自信和知识呈正相关。然而，只有少数参与者有资格获得此类证书。
