The usability of a digital diary from the perspectives of intensive care patients' relatives: A pilot study

_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.}
