One of the barriers identified in palliative care research is the lack of common criteria to describe the population.
The aim of this Delphi process was to obtain consensus on a basic set of core variables to describe or classify a palliative care cancer population.
This was a five-step international Delphi exercise. A total of 117 experts were invited to participate. Based on a literature review and analyses of existing minimum datasets for national databases, a list of 18 proposed variables was presented in the first Delphi round. The two first rounds focused on which variables to include, and several new variables were proposed. The three last Delphi rounds focused on how the agreed variables should be recorded. Consensus was defined as at least 70% agreement.
A total of 64 experts from 30 countries participated. High consensus was reached on 31 variables, divided between a 'patient form' - date of birth, gender, living situation, education, ethnicity and 12 symptoms - and a 'health-care personnel form' - patient's date of birth, principal diagnosis, date of the principal diagnosis, stage of the cancer disease, site of metastases, present anticancer treatment, main additional diagnoses, stage of the additional diagnoses, medication, weight loss, performance status, cognitive impairment, place of care and provision of care. It was more difficult to agree upon how to record the variables, but consensus was reached on all except ethnicity, vomiting and weight loss.
Consensus was reached on a set of core variables and how they should be recorded.
姑息治疗研究中发现的障碍之一是缺乏描述研究对象的通用标准。
本次德尔菲法的目的是就一套描述或分类姑息治疗癌症患者群体的核心变量达成共识。
这是一项五步国际德尔菲法活动。共邀请了117位专家参与。基于文献综述以及对国家数据库现有最小数据集的分析，在第一轮德尔菲法中列出了18个建议变量。前两轮聚焦于应纳入哪些变量，还提出了几个新变量。最后三轮德尔菲法聚焦于如何记录已达成共识的变量。共识定义为至少70%的一致意见。
来自30个国家的64位专家参与其中。就31个变量达成了高度共识，这些变量分为“患者表格”——出生日期、性别、生活状况、教育程度、种族以及12种症状——和“医护人员表格”——患者出生日期、主要诊断、主要诊断日期、癌症疾病分期、转移部位、当前抗癌治疗、主要附加诊断、附加诊断分期、用药情况、体重减轻、体能状态、认知障碍、护理地点和护理提供情况。就如何记录这些变量达成共识更难，但除种族、呕吐和体重减轻外，其他变量均达成了共识。
就一组核心变量以及如何记录这些变量达成了共识。
