Patient preferences for life-sustaining treatment are frequently unknown at critical moments, which often results in clinicians providing treatment that is not medically indicated and/or may not be consistent with patient desires. A consortium of Oregon health care professionals developed the Medical Treatment Coversheet (MTC) to standardize documentation of patient preferences in the out-of-hospital setting by having corresponding physician orders available at the patient's location. We describe a unique process of development, evaluation, and implementation of the MTC.
First, we conducted focus groups of providers to help draft the MTC. Second, the accuracy of MTC interpretation was determined by cohorts of acute and long-term care providers by indicating their treatment approach to three hypothetical written scenarios. They responded to the same scenarios twice, with and without the MTC. Responses were compared with each other and with ideal responses (most medically appropriate and in agreement with patient preferences) as defined by an expert panel. Finally, we are instituting pilot projects and developing a plan for statewide voluntary implementation of the MTC.
Urban and rural long-term care facilities and emergency medical service systems in Oregon.
Focus groups included 28 general internists practicing in urban and rural settings and five nurses working in a long-term care facility. In addition, 87 providers (19 primary care physicians, 20 emergency physicians, 26 paramedics, and 22 long-term care nurses) participated in the evaluation of the form by responding to hypothetical scenarios. Providers in long-term care facilities in both an urban and rural area helped with pilot implementation of the MTC. Use of the MTC in noninstitutional settings was not evaluated.
Suggestions from focus groups were incorporated into the form. For the hypothetical scenario responses, ideal appropriateness scores were analyzed, with a total possible score of 30 for each acute care provider and 15 for each long-term care provider. Statistically significant differences were determined using a paired t test. We report the experience of providers who helped with the pilot implementation of the form.
Focus groups would use the MTC and believed it would be useful for their patients. Comparing responses to the hypothetical scenarios without the MTC to those with the MTC, 37% of treatment decisions changed for acute care and 29% changed for long-term care providers. Changes were attributable overwhelmingly to withholding treatments consistent with patient preferences. Compared with the ideal, decisions were more appropriate for all specific treatments across all scenarios and clinician groups with the MTC, with one exception: some advanced emergency treatments were withheld inappropriately by 18% of acute care providers with the MTC, (chi-square = 15.94, P < .0001). For all scenarios combined, appropriateness scores increased significantly with the MTC for both acute care (16.4 to 22.3, P < .0001) and long-term care providers (8.8 to 12.2, P < .0001). Overall, providers helping with the pilot implementation were satisfied with the document, organizational endorsements, and available informational resources.
We describe our process for development, initial evaluation, and implementation of the MTC. In clinical scenarios overall, the MTC improves the appropriateness of clinicians' decisions about life-sustaining treatments. We are planning statewide implementation of the MTC after appropriate education of clinicians.
在关键时刻,患者对维持生命治疗的偏好往往不明,这常常导致临床医生提供的治疗在医学上并无必要,和/或可能不符合患者的意愿。俄勒冈州的一个医疗保健专业人员联盟开发了《医疗治疗覆盖表》(MTC),通过在患者所在地提供相应的医生医嘱,来规范院外环境中患者偏好的记录。我们描述了MTC独特的开发、评估和实施过程。
首先,我们组织了提供者焦点小组以帮助起草MTC。其次,急性和长期护理提供者群体通过表明他们对三种假设书面情景的治疗方法,来确定MTC解释的准确性。他们对相同情景进行了两次回应,一次有MTC,一次没有。将这些回应相互比较,并与专家小组定义的理想回应(最符合医学要求且符合患者偏好)进行比较。最后,我们正在开展试点项目,并制定一项在全州范围内自愿实施MTC的计划。
俄勒冈州的城乡长期护理机构和紧急医疗服务系统。
焦点小组包括28名在城乡环境中执业的普通内科医生和5名在长期护理机构工作的护士。此外,87名提供者(19名初级保健医生、20名急诊医生、26名护理人员和22名长期护理护士)通过回应假设情景参与了该表格的评估。城乡长期护理机构的提供者协助了MTC的试点实施。未评估MTC在非机构环境中的使用情况。
焦点小组的建议被纳入表格。对于假设情景的回应,分析了理想适宜性得分,每位急性护理提供者的总分可能为30分,每位长期护理提供者为15分。使用配对t检验确定统计学上的显著差异。我们报告了协助该表格试点实施的提供者的经验。
焦点小组会使用MTC,并认为它对他们的患者有用。将无MTC时对假设情景的回应与有MTC时的回应进行比较,急性护理提供者的治疗决策有37%发生了变化,长期护理提供者有29%发生了变化。这些变化绝大多数归因于根据患者偏好停止治疗。与理想情况相比,对于所有情景和临床医生群体中的所有具体治疗,有MTC时的决策更合适,但有一个例外:18%使用MTC的急性护理提供者不适当地停止了一些高级急救治疗(卡方 = 15.94,P < .0001)。对于所有情景综合来看,有MTC时急性护理提供者(从16.4到22.3,P < .0001)和长期护理提供者(从8.8到12.2,P < .0001)的适宜性得分均显著提高。总体而言,协助试点实施的提供者对该文件、组织认可和可用的信息资源感到满意。
我们描述了MTC的开发、初步评估和实施过程。在总体临床情景中,MTC提高了临床医生关于维持生命治疗决策的适宜性。我们计划在对临床医生进行适当培训后在全州范围内实施MTC。
