To determine what treatment decisions physicians will make when faced with a hypothetical incompetent elderly patient with life-threatening gastrointestinal bleeding and to examine the relative importance of physician characteristics and factors (legal and ethical concerns, hospital costs, level of dementia, patient's age, physician's religion, patient's wishes and family's wishes) in making those decisions.
Survey.
Family practice, medical and geriatrics rounds in academic medical centres and community hospitals in seven countries.
Physicians who regularly cared for incompetent elderly patients.
A self-administered questionnaire describing the elderly patient. Respondents were asked to choose one of four levels of care and to identify the level of importance factors had in making that decision. Older physicians, those less concerned about litigation, those for whom the level of dementia was important and those for whom the patient's age was important were expected to give less aggressive care than the other physicians.
Supportive care was chosen by 8.1% of the respondents, limited therapeutic care by 41.5%, maximum therapeutic care without admission to the intensive care unit (ICU) by 32.2% and maximum care with admission to the ICU by 18.2%. The patient's wishes were reported by 91.0% as being extremely or very important in choosing the treatment. Stepwise logistic regression analysis revealed that the following variables independently predicted the level of treatment: level of dementia, country of residence, duration of practice, legal concerns, patient's age and ethical concerns. These factors were significantly correlated with the physicians' treatment choices (p less than 0.05).
The importance that the physicians placed on the level of dementia was the strongest predictor of the level of care that would be provided. A societal consensus on the influence of cognitive function on the appropriate level of care as well as training of physicians in ethical issues are required.
确定医生在面对一名患有危及生命的胃肠道出血的老年无行为能力患者时会做出何种治疗决策,并研究医生特征和因素(法律和伦理问题、医院成本、痴呆程度、患者年龄、医生宗教信仰、患者意愿和家属意愿)在做出这些决策时的相对重要性。
调查。
七个国家的学术医疗中心和社区医院的家庭医疗、内科和老年病科查房。
经常照顾老年无行为能力患者的医生。
一份描述老年患者情况的自填式问卷。要求受访者从四种护理级别中选择一种,并确定各因素在做出该决定时的重要程度。预计年长的医生、那些不太担心诉讼的医生、那些认为痴呆程度很重要的医生以及那些认为患者年龄很重要的医生会比其他医生提供的治疗更保守。
8.1%的受访者选择了支持性护理,41.5%选择了有限的治疗性护理,32.2%选择了不入住重症监护病房(ICU)的最大程度治疗性护理,18.2%选择了入住ICU的最大程度护理。91.0%的受访者表示患者意愿在选择治疗方案时极其或非常重要。逐步逻辑回归分析显示,以下变量独立预测了治疗级别:痴呆程度、居住国家、行医年限、法律问题、患者年龄和伦理问题。这些因素与医生的治疗选择显著相关(p<0.05)。
医生对痴呆程度的重视是所提供护理级别最强的预测因素。需要就认知功能对适当护理级别影响达成社会共识,并对医生进行伦理问题培训。
