Prevalence of depression among heart failure inpatients and its associated socio-demographic factors: implications for personal-and family-based treatment management in health facilities in Vietnam.

OBJECTIVE: Our objective is to identify the prevalence of depression among inpatients with heart failure (HF), and to ascertain the factors associated with the depression from a wide spectrum of sociodemographic variables. MATERIALS AND METHODS: We conducted a hospital-based cross-sectional survey of prospectively collected data in inpatients with a diagnosis of HF at Vietnam National Heart Institute, Bach Mai Hospital (Hanoi, Vietnam) from July 2020 to July 2021. A sample size of 128 inpatients with HF was finally included. Primary outcome variable was depression ICD-10. RESULTS: The mean age was 62.34 (SD = 14.76). The sex ratio was 66 males to 62 females. The overall prevalence of depression ICD-10 was 46.88% among HF inpatients. The proportion of the depressed patients fluctuated between 37.21% and 83.33% by NYHA heart failure classification. Compared to the depressive prevalence among patients with NYHA class II, the odds were 8.43 times higher for those with NYHA class IV (OR univariate 8.43; 95% CI 1.63-43.46). Patient's age was significantly associated with increased prevalence of depression (OR multivariate 1.07; 95% CI 1.003-1.14). It was significantly higher odds of depression in HF patients who felt sadness after a diagnosis of an illness (OR multivariate 18.02, 95% CI: 4.21-77.08). Individuals with higher household economic status were less likely to be diagnosed with depression compared to those with lower household economic status (OR multivariate 0.15, 95% CI: 0.02-0.92). The odds of depression were significantly higher in HF patients who reported family conflict (OR multivariate 23.45, 95% CI: 1.29-423.55), and in those having the loss of a close family member (OR multivariate 38.62, 95% CI: 1.41-1055.98). CONCLUSIONS:   The prevalence of depression by ICD-10 was relatively high. Age of patient, sadness after a diagnosis of an illness, household economic status, family conflict and loss of a close family member were significantly associated with the depression among HF inpatients. Present results suggest a need for a disease management program addressing both psychological and HF aspects with the aim of improving health outcomes for the inpatients in Vietnam health facilities.
