Previous research on the impact of a diary on mental symptoms of PICS, PICS-F, and quality of life in former ICU patients and their relatives has focused specifically on a paper diary. While there has been research on the experiences of former ICU patients, relatives, and ICU nurses regarding the use of a digital diary, it is not known whether this diary has an impact on the psychological well-being and quality of life of former ICU patients and their relatives. A successful implementation of [the digital diary] enables this research. The aim of this study is, therefore, to provide an initial impression of the health-related effects of a digital diary on former ICU patients and their relatives.
