To characterize the informed consent process in routine, primary care office practice.
Cross-sectional, descriptive evaluation of audiotaped encounters.
Offices of primary care physicians in Portland, Oregon.
Internists (54%) and family physicians (46%), and their patients.
Audiotapes of primary care office visits from a previous study of doctor-patient communication were coded for the number and type of clinical decisions made. The discussion between doctor and patient was scored according to six criteria for informed decision making: description of the nature of the decision, discussion of alternatives, discussion of risks and benefits, discussion of related uncertainties, assessment of the patient's understanding and elicitation of the patient's preference. Discussions leading to decisions included fewer than two of the six described elements of informed decision making (mean 1.23, median 1.0), most frequent of these was description of the nature of the decision (83% of discussion). Discussion of risks and benefits was less frequent (9%), and assessment of understanding was rare (2%). Discussions of management decisions were generally more substantive than discussions of diagnostic decisions (p = .05).
Discussions leading to clinical decisions in these primary care settings did not fulfill the criteria considered integral to informed decision making. Physicians frequently described the nature of the decision, less frequently discussed risks and benefits, and rarely assessed the patient's understanding of the decision.
描述常规基层医疗门诊实践中的知情同意过程。
对录音问诊进行横断面描述性评估。
俄勒冈州波特兰市的基层医疗医生办公室。
内科医生(54%)和家庭医生(46%)及其患者。
在之前一项关于医患沟通的研究中,对基层医疗门诊的录音进行编码,统计做出的临床决策的数量和类型。根据知情决策的六个标准对医患之间的讨论进行评分:决策性质的描述、替代方案的讨论、风险和益处的讨论、相关不确定性的讨论、对患者理解情况的评估以及对患者偏好的引出。导致决策的讨论包含的知情决策所述六个要素少于两个(均值1.23,中位数1.0),其中最常见的是决策性质的描述(占讨论的83%)。风险和益处的讨论较少(9%),对理解情况的评估很少见(2%)。管理决策的讨论通常比诊断决策的讨论更具实质性(p = 0.05)。
在这些基层医疗环境中,导致临床决策的讨论未达到被视为知情决策不可或缺的标准。医生经常描述决策的性质,较少讨论风险和益处,很少评估患者对决策的理解。
