We sought to determine the prevalence, recognition, and consequences of mental impairment among chronic hemodialysis patients. We administered the Mini Mental Status Exam (MMSE), a brief validated method for assessing cognitive mental status that is commonly used by clinicians, to 84 patients from our dialysis units. To determine the clinical implications of mental impairment, we obtained Kt/V, albumin, protein catabolic rate, blood pressure, and hematocrit values. We found that 21% of subjects had mild mental impairment (MMSE 18 to 23) and that 11% had moderate-severe mental impairment (MMSE 0 to 17). We found no relationship between MMSE score and years on dialysis, Kt/V value, hematocrit value, or erythropoietin use. On univariate analysis, MMSE score was associated with albumin, protein catabolic rate, inter-dialytic weight gain, number of co-morbid conditions, number of hospitalizations. Outcomes on univariate analysis were further analyzed by multivariate analysis. There was an independent relationship between decrement in MMSE score and lower protein catabolic rate and increased hospitalization number and number of co-morbid conditions. Based on our findings, we recommend that clinicians routinely screen hemodialysis patients for mental impairment and target impaired patients for interventions to improve mental status and associated adverse outcomes.
