Aim To understand the individualization process of the standardized care plan (SCP) that nurses design for hospitalized patients. Background To apply the nursing process, it is advisable to use SCP to standardize the diagnosis, planning and evaluation stages. However, the fundamental element of this methodology is the individualization of the care plan. Design A qualitative study, framed within the constructivist paradigm and applying the Grounded Theory method, in accordance with Strauss and Corbin's approach. Methods Multicentre study. Theoretical sampling with maximum variation will be used. The data collection will consist of: in‐depth individual interviews, participant observation, document analysis, focus group, and the questionnaires for Critical Thinking Assessment in relation to clinical practice and Nursing Competency Assessment for hospital nurses. The qualitative data will be analysed according to the constant comparative method of Strauss and Corbin's Grounded Theory, which involves performing open, axial and selective coding. The questionnaire results will be used to make a qualitative analysis that will consist of a triangulation between the level of critical thinking, level of expertise and record of the individualization process performed by the nurses. This protocol was approved in July 2015. Discussion By knowing the possible stages used in the individualization of a SCP, together with the elements that facilitate or hinder said individualization and nurses’ attitudes and experiences regarding this phenomenon, it could help direct improvement strategies in the standardization and individualization process. In addition to recommendations for teaching and research. 目的 了解护理人员为住院患者设计的标准化护理计划(SCP)的个体化程序。 背景 为了适应护理过程,建议使用标准化护理计划来规范诊断、规划和评价阶段。然而,本方法的基本要素是护理计划的个体化。 设计 根据施特劳斯和科尔宾方法,在建构主义范式框架下,应用扎根理论方法进行定性研究。 方法 多中心研究。将采用最大变化的理论抽样。资料收集将包括:深度个人访谈、参与观察、文献分析、焦点小组以及针对临床实践的批判性思维评估问卷调查和医院护士的护理能力评估。定性数据将根据施特劳斯和科尔宾扎根理论的常量比较法,进行分析,其中包括执行开放、轴向和选择性的编码。问卷调查结果将用来进行定性分析,其中包括评判性思维水平、专业知识水平与护士负责的个体化程序记录之间的三角测量。本方案于2015年7月获得批准。 讨论 通过了解标准化护理计划之个体化的潜在阶段,以及促进或阻碍个体化的因素和护士对这种现象的态度和经验,除了可为教学和研究提供建议,还有助于对标准化和个性化过程中的改进策略提供指导。
