Effectiveness of a PRECEDE-based education intervention on quality of life in elderly patients with chronic heart failure

Abstract

BackgroundOne of the most important challenges in public health is to improve the quality of life in patients with chronic heart failure (CHF). Depression, self-care capacity, and quality of life interact each other in these patients. It’s difficult to treat with general education programs and conventional therapy. PRECEDE model is a comprehensive and exclusive theory-based education programs. Its effectiveness for reducing depression and increasing quality of life has been demonstrated in patients with coronary artery bypass grafting, type 2 diabetes, and the elderly. It has not been used in elderly patients with CHF. Thus, this study aims to investigate the effects of this model on self-care behaviors, depression, and quality of life in these patients.MethodsPatients who met the inclusion criteria were randomly assigned to the intervention or control group. All the patients received conventional medical care. The patients in the intervention group also received 9 sessions of education intervention based on the PRECEDE model and then followed up for 3 months after the intervention. Data were collected before and 3 months after the intervention using 4 questionnaires, namely a PRECEDE-based questionnaire to evaluate predisposing, reinforcing, and enabling factors; the 9-item European Heart Failure Self-care Behavior Scale (EHFScBS-9); the 9-item Personal Health Questionnaire (PHQ-9); and the Minnesota Living with Heart Failure Questionnaire (MLHFQ).ResultsNo significant differences were found in the mean scores for the predisposing, enabling, and reinforcing factors, and the mean total scores in EHFScBS-9, PHQ-9, and MLHFQ before the intervention between the intervention and control groups. After the intervention, the scores for the predisposing, reinforcing, and enabling factors increased significantly, and the mean total scores in EHFScBS-9, PHQ-9, and MLHFQ decreased significantly in the intervention group. In addition, these scores significantly differed from those of the control group. Furthermore, the MLHFQ score significantly correlated with the EHFScBS-9 and PHQ-9 scores.ConclusionThis study demonstrates a trend that PRECEDE model of health education promotion is effective in relieving depression symptoms, enhancing self-monitoring, and improving the quality of life of elderly patients with CHF.Trial registrationTrial registration number: ChiCTR-IOR-17012779; Trial registry: Chinese Clinical Trial Registry; Date registered: 22 Sep 2017; Retrospectively registered.

Self-care ability and influencing factors in chronic heart failure patients

“…[14]. Wang et al [15] found that education level was positively correlated with patients' abilities to self-manage medication, treatments, and administration of medication, and that higher education levels could facilitate compliance with adaptive healthy behaviours. Hailan et al [16] discovered that males tended to have a greater need for medical help at the onset of CHF than females, that patients in poorer health engaged in fewer activities, and that patients with low incomes had lower levels of self-care ability.…”

The effect of educational intervention based on precede proceed model on life quality in hypertensive patients

“…The results of other studies based on PRECEDE-PROCEED model show that this pattern is effective in enhancing life quality. The results of the study by Shore concerning improving life quality in relation to epilepsy [29], the study by Wang et al regarding life quality in the elderly with chronic heart failure [30], as well as the study by Zhu et al on the effect of educational intervention on improving physical health, as one of the dimensions of life quality of immigrant women workers [31] are in this regard. One has to note that the role of educational interventions in improving the life quality in different people, especially chronic diseases like hypertension, should not be ignored.…”

The Effects of Add-on Self-Care Therapy on Epidural Catheter Analgesia and Quality of Life in Patients after Surgical Stabilization of Multiple Rib Fractures

“…The self-care theory, rst introduced in 1959 by Dorothea Orem, has been demonstrated to reduce side effects of medical treatments and improve QoL among patients of various diseases [14][15][16]. It contains descriptions regarding the role of the nurse to help individuals who experiences inabilities in self-care.…”
