In HF patients with mild cognitive impairment, factors including HF knowledge, race, disease severity, social support, age, and education explained 19-22% of the variance in self-care domains (P<.001).
Cross-Sectional (n=125)
In hospitalized heart failure patients with mild cognitive impairment, adequate heart failure knowledge does not translate to adequate self-care, which is influenced by factors including social support, disease severity, age, and race.

BACKGROUND: Heart failure (HF) is associated with cognitive impairment, which could negatively affect a patient's abilities to carry out self-care, potentially resulting in higher hospital readmission rates. Factors associated with self-care in patients experiencing mild cognitive impairment (MCI) are not known. OBJECTIVE: This descriptive correlation study aimed to assess levels of HF self-care and knowledge and to determine the predictors of self-care in HF patients who screen positive for MCI. METHODS: The Montreal Cognitive Assessment was used to screen for MCI. In 125 patients with MCI hospitalized with HF, self-care (Self-care of Heart Failure Index) and HF knowledge (Dutch Heart Failure Knowledge Scale) were assessed. We used multiple regression analysis to test a model of variables hypothesized to predict self-care maintenance, management, and confidence. RESULTS: Mean (SD) HF knowledge scores (11.24 1.84) were above the level considered to be adequate (defined as >10). Mean (SD) scores for self-care maintenance (63.57 19.12), management (68.35 20.24), and confidence (64.99 16.06) were consistent with inadequate self-care (defined as scores <70). In multivariate analysis, HF knowledge, race, greater disease severity, and social support explained 22% of the variance in self-care maintenance (P < .001); age, education level, and greater disease severity explained 19% of the variance in self-care management (P < .001); and younger age and higher social support explained 20% of the variance in self-care confidence scores (P < .001). Blacks, on average, scored significantly lower in self-care maintenance (P = .03). CONCLUSION: In this sample, patients who screened positive for MCI, on average, had adequate HF knowledge yet inadequate self-care scores. These models show the influence of modifiable and nonmodifiable predictors for patients who screened positive for MCI across the domains of self-care. Health professionals should consider screening for MCI and identifying interventions that address HF knowledge and social support. Further research is needed to explain the racial differences in self-care.
Davis et al. (Wed,) conducted a cross-sectional in Heart failure with mild cognitive impairment (n=125). Predictors (HF knowledge, race, disease severity, social support, age, education) was evaluated on Self-care maintenance, management, and confidence scores (p=< .001). In HF patients with mild cognitive impairment, factors including HF knowledge, race, disease severity, social support, age, and education explained 19-22% of the variance in self-care domains (P<.001).
