Evaluation of Cognitive Characteristics among Nurses of Al-Zahra Hospital in Isfahan in Terms of Demographic Variables


Cognitive failures are one of the main reasons for nurses' inattention and reduced patient safety in hospitals. This study aimed to investigate the cognitive failure characteristics in nurses of Al-Zahra Hospital in Isfahan. For this purpose, a cognitive failure questionnaire was provided to nurses working in this treatment unit. After analyzing the data obtained from the questionnaires, the Mann-Whitney test and Kruskal-Wallis test were used. Based on the results of the Kruskal-Wallis test, there is no significant difference in the average of cognitive failure between different age groups (=4.77, p=0.18), different wards (=3.47, p=0.62), different employment statuses (=0.16, p=0.92) and different work experiences (=0.63, p=0.72). According to the results of the U Mann-Whitney test, statistically, between male and female nurses (Z=-0.77, Sig.=0.43), single and double occupational nurses (Z=-0.59, Sig.=0.55), nurses with different education (Z=-0.38, Sig.=0.702), different working hours (Z=-0.65, Sig.=0.51), being under psychiatric treatment and not being under psychiatric treatment (Z=-0.20, Sig.=0.83), the experience of mental illness in the last 6 months and the absence of such experience (Z=-0.53, Sig.=0.59), there is no significant difference between having a chronic disease and not having a chronic disease (Z=-0.93, Sig.=0.35) in terms of the average of cognitive failure. According to the results of this study, the studied parameters do not have a significant effect on the incidence of cognitive failures and therefore do not play a role in the occurrence of disorders in thinking, concentration and attention of nurses. Therefore, the cognitive failures that occurred in Al-Zahra Hospital are related to other parameters.
