Treatment outcomes and associated factors among chronic ambulatory heart failure patients at Jimma Medical Center, South West Ethiopia: prospective observational study

Background Heart failure has been one of the major causes of hospitalization across the world. Focusing on the treatment outcomes of ambulatory heart failure patients will reduce the burden of heart failure such as hospitalization and improve patient quality of life. Even if research is conducted on acute heart failure patients, there is limited data about treatment outcomes of chronic ambulatory heart failure patients. Therefore, this study aimed to assess treatment outcomes and associated factors of chronic ambulatory heart failure patients at Jimma Medical Center, South West Ethiopia. Methods A hospital-based prospective observational study was conducted on 242 chronic ambulatory heart failure patients at Jimma Medical Center from November 2020 to June 2021. The data were collected with pretested data collection format, and analyzed with Statistical Package for Social Sciences version 23. Both univariate and multivariate logistic regression model were used to identify factors associated with treatment outcomes of outpatient heart failure, and with a reported p value < 0.05, 95% confidence interval (CI) was considered statistical significance. Result From 242 patients, 126 (52.1%) were males and 121 (50.0%) patients were aged between 45 and 65 years. Regarding treatment outcomes, 51 (21.1%) of patients were hospitalized, and 58 (24.0%) and 28 (11.6%) of patients had worsened and improved clinical states respectively. Clinical inertia [AOR = 2.820; 95% CI (1.301, 6.110), p = 0.009], out-of-pocket payment [AOR = 2.790; 95% CI (1.261, 6.172), p = 0.011] and New York Heart Association class II [AOR = 2.534; 95% CI (1.170, 5.488), p = 0.018] were independent predictors of hospitalization. Conclusion Hospitalization of ambulatory heart failure patients was relatively high. More than half of the patients had clinical inertia. And also, this study showed most ambulatory HF patients had inadequate self-care. Clinical inertia, out-of-pocket payment, and New York Heart Association class II were independent predictors of hospitalization in ambulatory heart failure patients. Therefore, it is better to give more attention to ambulatory heart failure patients to prevent hospitalization and the burden of heart failure.
