Risk Factors for Multiple Hospitalizations of Elderly Patients with Chronic Heart Failure Worsens
Objective To explore the risk factors of multiple hospitalization in elderly patients with chronic heart failure worsens.Methods From January 2019 to December 2020,elderly patients who were hospitalized for exacerbation of chronic heart failure worsens and discharged with remission in Biyang County People's Hospital were consecutively included.The clinical features,treatment and follow-up for 12 months were collected.The end point of observation was the maximum number of hospitalizations per year.According to the annual maximum number of hospitalization,the study subjects were divided into multiple hospitalization group(annual maximum number of hospitalization≥2 times)and non-multiple hospitalization group(annual maximum number of hospitalization＜2 times).The normal characteristics were compared and multivariate logistic regression was used to analyze the risk factors of multiple hospitalization in elderly patients with chronic heart failure.Results A total of 361 patients were included,82(22.7％)patients were included in multiple hospitalizations group,279(77.3％)patients were included in non-multiple hospitalizations group.There were statistically significant differences between the two groups in age and complications(P＜0.05).Multivariable logistic regression analysis showed valvular heart disease(OR=1.992,95％CI 1.319-2.289,P=0.002),atrial fibrillation(OR=3.780,95％CI 1.790-4.675,P=0.038),renal insufficiency(OR=2.938,95％CI 1.233-6.312,P=0.004),and prior myocardial infarction(OR=1.765,95％CI 1.376-2.932,P=0.026)were independent risk factors for multiple hospitalizations,while female(OR=0.706,95％CI 0.687-0.986,P＜0.001)was the protective factor for multiple hospitalizations.Conclusion Valvular heart disease,atrial fibrillation,renal insufficiency,and prior myocardial infarction are related to an increased risk of multiple hospitalizations among elderly chronic heart failure worsens patients,while female is a protective factor for the risk of multiple hospitalizations.
