The purpose of this study was twofold. First, to identify current roles and future role perceptions for Certified Registered Nurse Anesthetists (CRNAs) using the delphi methodology. Second, to analyze the level of agreement or disagreement of anesthesiologists and CRNAs with the identified roles. A survey instrument was developed using the delphi methodology which involved five CRNAs and five anesthesiologists. The instruments with a dimensional rating scale were labeled "Current Roles for CRNAs" and "Future Role Perceptions for CRNAs." The former instrument contained 26 items and the latter contained 28 items. Participants in this study were randomly selected from the active memberships of the American Association of Nurse Anesthetists and the American Society of Anesthesiologists. Usable responses were obtained from 369 of the 684 CRNAs and 354 of the 1,400 anesthesiologists. Analysis of the data revealed there were significant differences between the two professions on all roles. There was evidence of extreme polarity on roles relating to expanded practice, independent practice, the role of CRNAs on the anesthesia care team, and nontraditional practice settings. CRNAs differed from anesthesiologists in their role as nurse anesthesia educators. Anesthesiologists who worked with CRNAs were influenced in their support of CRNA roles, except for roles in independent and expanded practice, and responded differently from anesthesiologists who did not work with CRNAs. The conclusions were as follows: 1. CRNAs and anesthesiologists differ in support for expanded practice in both current and future perceptions. 2. CRNAs and anesthesiologists differ on the issue of independent practice. 3. The perception of anesthesiologists relative to the anesthesia care team appeared to be influenced by a working relationship with CRNAs.(ABSTRACT TRUNCATED AT 250 WORDS)
本研究有两个目的。其一，运用德尔菲法确定注册护士麻醉师（CRNA）当前的角色以及对其未来角色的认知。其二，分析麻醉医生和注册护士麻醉师对所确定角色的认同或分歧程度。采用德尔菲法开发了一种调查问卷，涉及5名注册护士麻醉师和5名麻醉医生。带有维度评级量表的问卷分别被标记为“注册护士麻醉师的当前角色”和“注册护士麻醉师的未来角色认知”。前一份问卷包含26个项目，后一份包含28个项目。本研究的参与者是从美国护士麻醉师协会和美国麻醉医师协会的活跃会员中随机选取的。在684名注册护士麻醉师中，有369人给出了有效回复；在1400名麻醉医生中，有354人给出了有效回复。数据分析显示，在所有角色方面，这两个职业之间存在显著差异。在与扩大执业、独立执业、注册护士麻醉师在麻醉护理团队中的角色以及非传统执业环境相关的角色方面，存在极端两极分化的证据。注册护士麻醉师在担任护士麻醉教育工作者的角色方面与麻醉医生不同。与注册护士麻醉师共事的麻醉医生在支持注册护士麻醉师的角色方面会受到影响，但独立执业和扩大执业方面的角色除外，并且他们的回答与未与注册护士麻醉师共事的麻醉医生不同。研究结论如下：1. 注册护士麻醉师和麻醉医生在当前及未来对扩大执业的支持方面存在差异。2. 注册护士麻醉师和麻醉医生在独立执业问题上存在分歧。3. 麻醉医生对麻醉护理团队的认知似乎受到与注册护士麻醉师工作关系的影响。（摘要截选至250字）
