Application of ICU electronic diary platform based on co-design concept in Chinese critically ill patients: a mixed methods study protocol.

introductionCritically ill patients are at a heightened risk for post-traumatic stress disorder (PTSD). While the intensive care unit (ICU) diary has been shown to improve the mental health and quality of life of ICU patients, the handwritten version still has some limitations such as a lack of support for multimedia content and writing by remote family members, as well as being time-consuming and labour-intensive. We hypothesise that constructing an ICU electronic diary platform based on a co-design approach and verifying its applicability could alleviate these limitations, making the ICU diary more convenient for users. METHODS AND ANALYSIS: This sequential exploratory mixed-methods study will consist of four consecutive phases: understanding the ICU diary research content and implementation, developing an ICU electronic diary platform after conducting qualitative interviews with stakeholders, verifying the applicability of the platform and verifying its effectiveness. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Biomedical Research Ethics Committee of the Affiliated Hospital of Zunyi Medical University (approval number: KLL-2023-602). The results of this study will be distributed through peer-reviewed journals. TRIAL REGISTRATION NUMBER: Chinese Clinical Trial Register (ChiCTR2400079903).
