Patients' views on the quality of care are important and it is desirable that these can be assessed using short, yet valid and reliable instruments. The aim of the work reported here was to develop and test a short version of an established questionnaire: Quality from the Patient's Perspective (QPP). Patients (n=162, 79% response rate) receiving care at medical and surgical departments in two Swedish hospitals responded to the original QPP as well as to a newly developed short version. An ethical research committee approved the study. Pearson correlations were computed between the long and short forms and differences between means were analysed with t-tests. Reliability was estimated by computing Cronbach alpha coefficients. Correlations of acceptable size were found between the short form and the original QPP. The short form also had acceptable reliability coefficients. The strengths of the work are that the items in the short version are derived from a patient perspective and are formulated in words used by patients; the items still have a theoretical foundation, which makes the interpretation of results more meaningful; global formulations such as "What do you think about your care?" have been avoided; the short format should make the questionnaire more attractive for many patients to respond to. Limitations are that results indicate that the short form does not fully measure what the long form does. Therefore, when the short form is used in practice, a two-step procedure is suggested, where a follow-up is done with a selection of items from the original long form. This selection could be restricted to areas where problems may be suspected, based on the results from the short form.
患者对医疗质量的看法很重要，理想的情况是能够使用简短、有效且可靠的工具对其进行评估。本文所报告工作的目的是开发并测试一份既定问卷的简短版本：《患者视角的质量》（QPP）。在瑞典两家医院的内科和外科接受治疗的患者（n = 162，应答率79%）对原始的QPP以及新开发的简短版本进行了回应。一项伦理研究委员会批准了该研究。计算了长版和短版之间的皮尔逊相关性，并通过t检验分析了均值之间的差异。通过计算克朗巴哈α系数来估计信度。在短版和原始QPP之间发现了可接受大小的相关性。短版也具有可接受的信度系数。这项工作的优点在于，短版中的项目源自患者视角，并用患者使用的语言表述；这些项目仍有理论基础，这使得结果的解释更有意义；避免了诸如“你如何看待你的治疗？”这样的总体表述；简短的形式应该会使问卷对许多患者更具吸引力，使其愿意做出回应。局限性在于，结果表明短版并未完全涵盖长版所测量的内容。因此，在实际使用短版时，建议采用两步程序，即从原始长版中选择一些项目进行后续跟进。根据短版的结果，这种选择可以限制在可能存在问题的领域。
