Intensive care unit nurses' knowledge and attitudes towards older adults with COVID-19: A cross-sectional survey

Older adults constitute the majority of patients admitted to COVID-19 intensive care units (ICUs). The knowledge and attitudes of ICU nurses towards older adults diagnosed with COVID-19 significantly impact the quality of treatment and nursing care they deliver.

The objective of this study was to determine the ICU nurses' knowledge and attitudes towards older adults with COVID-19.

This descriptive and cross-sectional study was conducted between February and October 2021. The sample consisted of 112 ICU nurses from a public hospital and three university hospitals. Demographic data were collected together with the Nurse COVID-19 Knowledge Level Assessment Form (NKLAF) and the Kogan's Attitudes Toward Old People Scale (KAOPS). The data were analysed using the independent-groups t-test, one-way analysis of variance, Mann-Whitney U Test (Z score), Kruskale-Wallis Variance Test, post hoc test, and Spearman's correlation analysis.

Intensive care nurses had a mean NKLAF score of 21.29 ± 2.63 (mean difference: 21.24). They had a mean KAOPS score of 129.37 ± 15.20 (mean difference: 129.32). There was no correlation between NKLAF and KAOPS scores (r = 0.163, p > 0.05). Female nurses had a significantly higher mean NKLAF score than their male counterparts (Z: -2.733, p = 0.006). The intensive care nurses with bachelor's degrees had a significantly higher mean KAOPS score than those with associate degrees (KW: 6.888, p = 0.032).

The results indicate that ICU nurses know enough about COVID-19 and have positive attitudes towards older adults diagnosed with it. Moreover, some descriptive characteristics affect the knowledge and attitudes of ICU nurses towards older adults. Therefore, nurses should consider these factors when planning interventions to enhance their care for older adults.
