ABSTRACT
BACKGROUND: Diaries have been used regularly in international settings as an evidence-based and easily applicable intervention following a person-centred approach in the intensive care unit (ICU). In addition, a diary web application known as 'Post-ICU' has been implemented. AIM: To explore the usability of an innovative digital diary from the perspectives of intensive care patients' relatives. STUDY DESIGN: A cross-sectional online survey study was applied among a convenience sample of relatives in the ICUs of two hospitals in the Netherlands. The investigator-developed questionnaire included, among other things, items with the appreciation of the layout, user friendliness and functionality of the diary. Relevance and applicability were rated between 1 and 10. Data were analysed with SPSS© software, version 27, and reported as the means (±standard deviation [SD]) and percentages. RESULTS: Sixty-three relatives with an average age of 51 years (SD ± 14.3) participated in the study; there was a slight predominance of women (57%). All but one participant found using the digital diary easy and were able to upload photos to the diary. The participants had invited other relatives (75%) and nurses (61%) to write in the diary, which they viewed as easily feasible (89%). The relevance and applicability of the diary were rated with mean scores of 8.1 (SD ± 1.9) and 8.3 (SD ± 1.6), respectively. CONCLUSIONS: The participants found the Post-ICU diary web application highly valuable and easily feasible. Perceived ease of use, perceived usefulness and technophobia were not found to influence the usability of the digital diary. RELEVANCE TO CLINICAL PRACTICE: The implementation of this new digital tool supports a person-centred ICU policy because of its focus on the personal diary entries of the patient and the collaborative writing process featuring relatives and professionals.
