Patient autonomy has been promoted as the most important principle to guide difficult clinical decisions. To examine whether practising physicians indeed value patient autonomy above other considerations, physicians were asked to weight patient autonomy against three other criteria that often influence doctors' decisions. Associations between physicians' religious characteristics and their weighting of the criteria were also examined.
Mailed survey in 2007 of a stratified random sample of 1000 US primary care physicians, selected from the American Medical Association masterfile. Physicians were asked how much weight should be given to the following: (1) the patient's expressed wishes and values, (2) the physician's own judgment about what is in the patient's best interest, (3) standards and recommendations from professional medical bodies and (4) moral guidelines from religious traditions.
Response rate 51% (446/879). Half of physicians (55%) gave the patient's expressed wishes and values "the highest possible weight". In comparative analysis, 40% gave patient wishes more weight than the other three factors, and 13% ranked patient wishes behind some other factor. Religious doctors tended to give less weight to the patient's expressed wishes. For example, 47% of doctors with high intrinsic religious motivation gave patient wishes the "highest possible weight", versus 67% of those with low (OR 0.5; 95% CI 0.3 to 0.8).
Doctors believe patient wishes and values are important, but other considerations are often equally or more important. This suggests that patient autonomy does not guide physicians' decisions as much as is often recommended in the ethics literature.
患者自主权已被推崇为指导艰难临床决策的最重要原则。为了探究执业医师是否真的将患者自主权置于其他考量因素之上,研究人员要求医师们在患者自主权与另外三个常常影响医生决策的标准之间进行权衡。同时还考察了医师的宗教特征与其对这些标准的权衡之间的关联。
2007年对从美国医学协会主文件中选取的1000名美国初级保健医师进行分层随机抽样并邮寄调查问卷。医师们被问及应给予以下各项多大权重:(1)患者表达的意愿和价值观;(2)医师自己对患者最佳利益的判断;(3)专业医学机构的标准和建议;(4)宗教传统的道德准则。
回复率为51%(446/879)。一半的医师(55%)给予患者表达的意愿和价值观“尽可能高的权重”。在比较分析中,40%的医师给予患者意愿的权重高于其他三个因素,13%的医师将患者意愿排在其他某些因素之后。有宗教信仰的医生往往给予患者表达的意愿较低的权重。例如,内在宗教动机强烈的医生中,47%给予患者意愿“尽可能高的权重”,而内在宗教动机较弱的医生中这一比例为67%(比值比0.5;95%置信区间0.3至0.8)。
医生认为患者的意愿和价值观很重要,但其他考量因素往往同样重要或更重要。这表明患者自主权在指导医师决策方面,并不像伦理文献中经常建议的那么有效。
