To determine the relative value that patients place on consent for procedures in the emergency department (ED) and to define a set of procedures that fall in the realm of implied consent.
A questionnaire was administered to a convenience sample 134 of 174 patients who were seen in the ED of a Midwestern teaching hospital. The questionnaire asked how much time they believed was necessary to give consent for various procedures. Procedures ranged from simple (venipuncture) to complex (procedural sedation).
Participants valued a simple blood draw at a low mean of 1.02 minutes of extra time and a lumbar puncture at a high mean of 7.78 minutes. Of all participants 52% and 48% noted a time-value of "0" time on blood draw and intravenous line starts, respectively, indicating that they desire no additional consent for these procedures.
Defining a set of ED procedures covered under implied consent will be difficult because many patients value formal consent for even the simplest procedure.
确定患者对急诊科（ED）手术同意书的相对重视程度，并定义一系列属于默示同意范围内的手术。
对中西部一家教学医院急诊科就诊的174名患者中的134名进行了便利抽样问卷调查。问卷询问了他们认为同意各种手术需要多少时间。手术范围从简单的（静脉穿刺）到复杂的（程序性镇静）。
参与者认为简单的抽血平均额外需要1.02分钟，腰椎穿刺平均需要7.78分钟。在所有参与者中，分别有52%和48%的人表示抽血和开始静脉输液的时间价值为“0”分钟，这表明他们不希望对这些手术进行额外的同意。
定义一系列默示同意涵盖的急诊科手术将很困难，因为许多患者即使对最简单的手术也重视正式同意。
