When curative treatments are no longer options for patients dying of cancer, the focus of care often turns from prolonging life to promoting quality of life (QOL). Few data exist on what predicts better QOL at the end of life (EOL) for advanced cancer patients. The purpose of this study was to determine the factors that most influence QOL at the EOL, thereby identifying promising targets for interventions to promote QOL at the EOL.
Coping With Cancer is a US multisite, prospective, longitudinal cohort study of 396 advanced cancer patients and their informal caregivers who were enrolled from September 1, 2002, through February 28, 2008. Patients were followed up from enrollment to death a median of 4.1 months later. Patient QOL in the last week of life was a primary outcome of Coping With Cancer and the present report.
The following set of 9 factors, preceded by a sign indicating the direction of the effect and presented in rank order of importance, explained the most variance in patients' QOL at the EOL: 1 = (-) intensive care unit stays in the final week (explained 4.4% of the variance in QOL at the EOL), 2 = (-) hospital deaths (2.7%), 3 = (-) patient worry at baseline (2.7%), 4 = (+) religious prayer or meditation at baseline (2.5%), 5 = site of cancer care (1.8%), 6 = (-) feeding-tube use in the final week (1.1%), 7 = (+) pastoral care within the hospital or clinic (1.0%), 8 = (-) chemotherapy in the final week (0.8%), and 9 = (+) patient-physician therapeutic alliance at baseline (0.7%). The vast majority of the variance in QOL at the EOL, however, remained unexplained.
Advanced cancer patients who avoid hospitalizations and the intensive care unit, who are less worried, who pray or meditate, who are visited by a pastor in the hospital/clinic, and who feel a therapeutic alliance with their physicians have the highest QOL at the EOL.
当治愈性治疗不再是癌症晚期患者的选择时,护理重点往往从延长生命转向提高生活质量(QOL)。关于哪些因素能预测晚期癌症患者临终时更好的生活质量的数据很少。本研究的目的是确定在临终时对生活质量影响最大的因素,从而确定有望改善临终生活质量的干预目标。
“应对癌症”是一项在美国多地点开展的前瞻性纵向队列研究,纳入了396例晚期癌症患者及其非正式护理人员,他们于2002年9月1日至2008年2月28日入组。患者从入组开始随访至死亡,中位随访时间为4.1个月。患者临终前一周的生活质量是“应对癌症”研究及本报告的主要结局指标。
以下9个因素,前面带有表示效应方向的符号,并按重要性排序,解释了临终时患者生活质量的大部分变异:1 =(-)临终前一周入住重症监护病房(解释了临终时生活质量变异的4.4%),2 =(-)在医院死亡(2.7%),3 =(-)基线时患者担忧(2.7%),4 =(+)基线时进行宗教祈祷或冥想(2.5%),5 =癌症护理地点(1.8%),6 =(-)临终前一周使用饲管(1.1%),7 =(+)医院或诊所内的牧师关怀(1.0%),8 =(-)临终前一周进行化疗(0.8%),9 =(+)基线时患者与医生的治疗联盟(0.7%)。然而,临终时生活质量的绝大多数变异仍无法解释。
避免住院和入住重症监护病房、担忧较少、进行祈祷或冥想、在医院/诊所接受牧师探访以及与医生建立治疗联盟的晚期癌症患者在临终时生活质量最高。
