Abstract
Purpose This study aimed to identify gender differences with regard to the impact of change in cognitive function on functional status 3 months after receiving critical care. Design and Methods This prospective cohort study investigated 152 intensive care unit (ICU) patients. Their functional status and cognitive function were assessed using the validated Korean version of the Modified Barthel Index and Mini-Mental State Examination, respectively. Hierarchical regression was used to evaluate the impact of change in cognitive function on functional status in ICU survivors by gender. Findings The proportion of women suffering from consistent cognitive impairment was significantly higher than that of men. Women had a rate of improvement to normal cognitive function within 3 months after discharge that was higher than that of men. Functional status 3 months after discharge was significantly lower for patients whose cognitive impairment was consistent than that for those whose cognitive function was normal. The impact of change in cognitive function on men (R(2)change = .28) was greater than that on women (R(2)change = .13). Conclusions Persistent cognitive impairment after critical illness had a negative effect on functional status in ICU survivors. Importantly, the negative impact of consistent cognitive impairment was greater in men than in women. Clinical Relevance Early careful assessment of functional and cognitive status after critical illness is warranted. Strategies addressing the gender-specific characteristics related to cognitive improvement should also be developed.
