Nurses' Knowledge, Attitude and Practice in Nutrition Management of Hospitalised Adults: A Mixed‐Methods Study

ABSTRACT Aim(s) To examine nurses' knowledge, attitude and practice regarding nutrition management in hospitalised adults and explore their views on it. Design A mixed‐method approach combining cross‐sectional and descriptive qualitative methods. Methods 379 enrolled/registered nurses working in acute or intensive units of a tertiary hospital were recruited between 24th August 2023 and 3rd December 2023. Participants completed a questionnaire on their sociodemographic profile, knowledge, attitude and practice (KAP) regarding nutrition management. Data analysis was conducted using R software, reporting levels of KAP and its associations with sociodemographic factors. Mann–Whitney U and Kruskal–Wallis tests were used for non‐normally distributed knowledge and practice scores (reported as median and interquartile range). Two‐sample t ‐tests and ANOVA were used for normally distributed attitude scores (reported as mean and standard deviation). 21 of the participants from the quantitative study were either purposively sampled or snowballed from the quantitative study to undergo semi‐structured interviews (physically or virtually face‐to‐face), which were transcribed verbatim and analysed using content analysis. Results The mean scores on KAP were 61.6, 19.4 and 22.8, respectively. Knowledge varied significantly by educational level ( p < 0.001), while attitudes also differed based on education ( p = 0.001) and years of employment ( p = 0.019). Practice scores showed differences based on subspeciality ( p = 0.032), nursing rank ( p < 0.001) and years of employment ( p = 0.004). Findings identified barriers to effective nutrition management, including prioritisation issues, varying professional roles, limited autonomy and resource shortages. It also emphasises nurses' roles in nutrition management and strategies such as nurses' autonomy and family members involvement to improve nutrition management. Conclusion Sociodemographic factors significantly influence nurses' KAP in nutrition management, revealing knowledge deficits, low prioritisation and time constraints. Tailored education and training, increased autonomy, resource expansion and greater family involvement can enhance nurses' KAP in nutrition management.
