This study analyzes the elements that compose the emergency physicians' criterion for selecting elderly patients for intensive care treatment. This issue has not been studied in-depth.
A cross-sectional study was conducted at 4 university teaching hospitals, covering 101 randomly selected elderly patients admitted to emergency department and their respective physicians. Physicians were asked to forecast their plans for treatment or therapeutic abstention, in the event that patients might require aggressive measures (cardiopulmonary resuscitation or admission to critical care units). Data were collected on physicians' reasons for taking such decisions and their patients' functional capacity and cognitive status (Katz index and Informant Questionnaire on Cognitive Decline in the Elderly). A logistic regression model was constructed taking physicians' decisions as the dependent variables and adjusting for patient factors and physician impressions.
The functional status reported by reliable informants and the mental status measured by validated instruments were not coincident with the physicians' perception (functional status κ, 0.47; mental status κ, 0.26). A multivariate analysis showed that the age and the functional and mental status of patients, as perceived by the physicians, were the variables that better explained the physicians' decisions.
Physicians' impressions on the functional and mental status of their patients significantly influenced their selection of patients for high-intensity treatments despite the fact that some of these impressions were not correct.
本研究分析了构成急诊医师选择老年患者进行重症监护治疗标准的要素。这个问题尚未得到深入研究。
在 4 所大学教学医院进行了一项横断面研究,涵盖了 101 名随机选择的老年患者及其各自的医师。要求医师预测他们在患者可能需要积极治疗(心肺复苏或入住重症监护病房)的情况下的治疗计划或治疗放弃。收集了医师做出这些决定的原因以及患者的功能能力和认知状态(Katz 指数和认知下降老年知情者问卷)的数据。构建了一个逻辑回归模型,将医师的决策作为因变量,并调整了患者因素和医师印象。
可靠信息提供者报告的功能状态和经过验证的仪器测量的精神状态与医师的感知不一致(功能状态 κ,0.47;精神状态 κ,0.26)。多变量分析表明,患者的年龄以及医师感知到的功能和精神状态是更好地解释医师决策的变量。
尽管有些印象并不正确,但医师对患者功能和精神状态的印象会显著影响他们选择接受高强度治疗的患者。
