Predictive Factors of mortality among heart failure patients in Buri Ram Hospital Fiscal Years 2018-2020

Abstract

Background: Heart failure is a major cause for hospitalizations and high mortality rates. Outcomes following heart failure (HF) hospitalizations are poor.
Objective: This study aimed to investigate the mortality rate of heart failure, the risk factors related to mortality of heart failure in Buri Ram Hospital.
Methods: It’s was conducted as a retrospective case control study. The sample of 2,095 heart failure patients admitted to Buri Ram Hospital between October 2018 and September 2020 were included. A total of 290 subjects were selected by systemic sampling, 1:1. Data were collected by the retrospective medical review and analyzed using by descriptive statistics Chi-square test Fisher’s exact and Multivariable logistic regression
Results: The overall Heart Failure Mortality rate was 7.2%, a Predictive Factors of mortality in patients with heart failure were significantly associated with Pneumonia (OR 2.32 95%CI 1.01-5.33 p=0.047), Cardiac arrhythmia (OR 3.83 95%CI 1.76-8.33 p=0.001), Acute respiratory failure (OR 5.79 95%CI 2.88-11.63 p<0.001), Shock (OR 16.66 95%CI 5.06-54.90 p<0.001), and serum albumin level ≤ 3.4 g/dL (OR 3.59 95%CI 1.78-7.23 p< 0.001). Presence of all five factors have a positive predictive value of 80%.
Conclusions: The finding of this study offers specific insights for care of heart failure patients. These data can assist clinical assessment of patient symptom severity to provide appropriate interventions. That is, patients with the five aforementioned co-morbidities of pneumonia, cardiac arrhythmia, acute respiratory failure, shock, and serum albumin levels ≤ 3.4 g/dL in the hospital setting can be more rapidly treated to decrease heart failure mortality outcomes.
