Measuring Integrated Care from the Perspective of Patients: Adaptation and Validation of a Generic Patient Reported Questionnaire (PPIC)

随着德国采用不同类型和不同水平的综合护理来改善其支离破碎的医疗体系，评估这些举措对患者结局的影响变得至关重要。这些成果与卫生政策研究、卫生保健提供者、卫生服务管理和研究以及质量改进项目特别相关。我们建议修改和验证德国版的患者综合护理感知问卷(PPIC)，该问卷可以得出患者体验和以患者为中心的综合护理结果。除了改编的PPIC，我们还将提供支持文档和参考价值。问卷调整将包括PPIC的向前和向后翻译；就该仪器采访患者和卫生保健专家；以及在一小部分患者中预先测试德国PPIC。由于没有衡量综合护理的金标准，我们将招募已知综合护理水平不同的患者组来测试该工具的有效性。我们将比较纳入综合护理的患者和未纳入综合护理的患者：背部疼痛、损伤和门诊患者。我们将评估可接受性、维度和结构效度。德国PPIC将提供给对评估综合护理感兴趣的研究人员和/或其他利益相关者。

As different types and levels of integrated care are adopted in Germany to improve its fragmented health care system, evaluating the impact of these initiatives on patient outcomes becomes crucial. These outcomes are particularly relevant to health policy research, health care providers, health service management and research and quality improvement projects. We propose to adapt and validate a German version of The Patient Perceptions of Integrated Care Questionnaire (PPIC) which elicits patient experiences and patient centered outcomes of integrated care. Along with the adapted PPIC, we will also provide supporting documentation and reference values. Questionnaire adaptation will involve forward and backward translations of the PPIC; interviewing patients as well as health care experts regarding the instrument; and pre-testing the German PPIC in a small group of patients. Because there is no gold standard for measurement of integrated care, we will recruit patient groups known to differ in levels of integrated care to test validity of this instrument. We will compare patients enrolled and patients not enrolled in integrated care: back pain, injury and ambulatory patients. We will assess acceptability, dimensionality and construct validity. The German PPIC will be made available for researchers and/or other stakeholders interested in assessing integrated care.
