The retrospective part of the IKARUS Project (Incidence of Skeletal Related Events in Breast Cancer) was focused on monitoring the incidence of skeletal related events in patients with metastatic breast cancer treated in the Czech and Slovak Republics.The aim was to describe the experience with data collection management in the conditions of the Czech and Slovak Republics.
Retrospective collection of data in multi-centre, non-interventional, epidemiological and explorative studies. Female patients diagnosed since 2000 were involved in the project in order to respect the five-year period of monitoring and to describe the treatment of the period.
During the initiation phase of the retrospective study each of the 18 Complex Cancer Centres in the Czech Republic (see www.linkos.cz) and 18 chosen oncology centres in the Slovak Republic were addressed. In the end, data were collected from 13 oncology centres in the Czech Republic and 12 oncology centres in the Slovak Republic. The initial plan to enrol 650 patients was not completed; data on 254 patients from the Czech Republic and 125 patients from the Slovak Republic were finally analysed.The effectiveness of retrospective data collection in the conditions of Czech and Slovak oncology corresponded with the possibilities of access to data of formerly diagnosed and treated patients. In searching for retrospective data the present hospital information systems could not be used in most oncology centres.Therefore, the cost of retrospective data collection was estimated and was shown to be relatively high.
The binding methodical conclusion is that unless a systemic change is made in the functionality of hospital information systems and standardised electronic documentation is introduced, the retrospective collection of clinical data in our conditions will be associated with high costs and a relatively low recovery factor.
IKARUS项目(乳腺癌骨相关事件的发生率)的回顾性部分着重于监测捷克和斯洛伐克共和国接受治疗的转移性乳腺癌患者的骨相关事件发生率。目的是描述在捷克和斯洛伐克共和国的条件下进行数据收集管理的经验。
在多中心、非干预性、流行病学和探索性研究中进行回顾性数据收集。为了符合五年监测期并描述该时期的治疗情况,纳入了自2000年起被诊断的女性患者参与该项目。
在回顾性研究的启动阶段,联系了捷克共和国的18个综合癌症中心(见www.linkos.cz)以及斯洛伐克共和国的18个选定肿瘤中心。最终,从捷克共和国的13个肿瘤中心和斯洛伐克共和国的12个肿瘤中心收集到了数据。最初纳入650名患者的计划未完成;最终分析了来自捷克共和国的254名患者和来自斯洛伐克共和国的125名患者的数据。在捷克和斯洛伐克肿瘤学条件下进行回顾性数据收集的有效性与获取先前诊断和治疗患者数据的可能性相符。在搜索回顾性数据时,大多数肿瘤中心无法使用现有的医院信息系统。因此,对回顾性数据收集的成本进行了估算,结果显示成本相对较高。
具有约束力的方法性结论是,除非医院信息系统的功能发生系统性改变并引入标准化电子文档,否则在我们的条件下进行临床数据的回顾性收集将伴随着高成本和相对较低的回收率。
