Background
Heart failure (HF) is a complex clinical syndrome resulting from structural and functional heart problems, such as impairment of ejection fraction in ventricles and a low level of tissue or organ perfusion [
1]. The global burden of HF has been increasing, with 26 million patients suffering from HF globally [
2]. Recently, governments and policymakers have begun to pay attention to the readmission rate of HF patients to reduce unnecessary health care costs [
3]. The 30-day readmission rates for HF in developed regions, such as the United States (US) and Europe, are greater than 20 % [
4]. In Korea, the prevalence of HF has been increasing steadily since 2002 [
5], and the readmission rate of HF patients (27.6 %) is as high as in developed countries [
6]. The US started the hospital readmission reduction program (HRRP), which reduces the payment to hospitals with excess readmissions, in 2012 and chose HF as a target disease. The Korean government has also used readmission rate as a hospital quality indicator since 2016. After the HRRP was implemented, the readmission rate of HF patients in the US decreased slightly, but their short-term mortality rate increased [
7]. In other words, either hospitals did not allow hospitalization of severe HF patients, or high-quality care services are required to enhance self-care in the community and at home after discharge.
It is generally known that HF is a common disease in elderly patients [
8], and that HF patients have difficulties in self-management because of the complexity of the disease characteristics [
9]. Care for HF patients includes complex medication adherence, symptom management, weight management, dietary management, and physical activity [
10]. Effective self-management interventions for HF patients could theoretically improve their health outcomes, including readmission, short-term mortality, and quality of life [
11]. However, a meta-analysis result from 5,264 HF patients showed that self-management interventions were ineffective in reducing readmission rate [
12]. Some studies have suggested that the low efficacy of self-management interventions was caused by the knowledge gap between health care professionals (HCPs) and patients [
13,
14]. A previous study reported that fewer than 10 % of all patients who received discharge education understood what they had learned [
15]. In addition, HF patients adhered to their prescribed medication regimes but did not follow the recommended behavioral changes, including physical activity and weight monitoring [
16]. These findings indicate that effective discharge education is needed to improve self-management among HF patients.
Educational interventions using the teach-back method (TBM) for chronically ill patients who have difficulties in self-management have improved knowledge, adherence, self-efficacy, self-care skills [
17], and readmission rates [
18]. The TBM is defined as a communication confirmation method used by HCPs to confirm whether a patient or caregiver understands what is being explained to them [
19,
20]. Several studies have identified the effectiveness of TBM for discharge education, finding that it increased knowledge retention, improved self-care, and reduced the readmission rate for HF patients [
21‐
24]. Boyde et al.’s (2018) randomized controlled trial showed that self-care educational intervention using TBM for HF patients effectively reduced unplanned hospital readmission by 30 % [
21]. Also, Dihn et al.’s (2019) presented that the discharge education program using TBM for patients with HF improved knowledge and self-care maintenance [
22]. These results indicated that the discharge education using TBM for HF patients could be improved not only the knowledge aspect but also the clinical outcomes. However, previous studies lacked a detailed description of the program development process.
To our knowledge, no previous study used TBM in Korea. Several studies to improve self-management among HF patients were recently conducted in Korea, but they focused only on a health diary [
25] and telephone follow up [
26]. They did not consider effective education strategies such as TBM or essential outcomes including readmission rate. Therefore, our aims in this study were to develop a discharge education program using TBM, to evaluate the quality of the program, and to share the program development process in detail with researchers and HCPs.
Discussion
Our main goal was to develop a discharge education program using TBM for HF patients. Our evaluation of the HEART program found that the content was valid, and the educational material was appropriate for both providers and patients.
The TBM was designed to deliver a discharge education program. Growing evidence indicates that discharge education using TBM for HF patients effectively improves health outcomes compared with other educational methods [
22‐
24]. Howie-Esquivel and colleagues (2015) compared 548 elderly patients who received TBM education with 485 elderly patients who received usual care. The 30-day readmission rate in the TBM group was significantly lower than in the control group (12 % TBM group vs. 19 % usual care group). Recently, Dihn et al. (2019) conducted a cluster randomized controlled trial to test the effectiveness of a discharge education program using TBM among 140 adult patients with HF in Vietnam [
22]. They found that the TBM group had significantly higher knowledge and self-care maintenance than the control group. However, those previous studies lacked detailed information about how TBM was used in the education programs. We are contributing methodologically by describing and sharing our program development process in detail. We have also added teach-back questions about attitude and skill, in addition to teach-back questions about self-management knowledge. Of course, TBM is a way to identify and close the knowledge gap between HCPs and patients [
19,
20]; therefore, measuring knowledge is the most important metric. However, given that the ultimate goal of educational interventions to improve self-management is to change behaviors and attitudes [
11], teach-back questions about attitudes and skills could also be helpful.
We used the ADDIE model to develop our discharge education program. ADDIE is a well-known instructional-systems design model that education technologists and instructional designers use for curriculum development [
38]. The strengths of ADDIE include a systematic approach to generating a program and a robust and logical process for developing a program. It also provides an essential process to design engaging learning and training programs [
38]. However, it does not address the needs and factors during the analysis process. We overcame the shortcomings of the ADDIE model by conducting a needs assessment using focus group interviews during the analysis phase. We recommend performing a needs assessment when using the ADDIE model to develop training programs for patients.
The content validity and user validity of the HEART program were deemed suitable by patients and providers. In particular, patients rated the understandability as 90.2 % and the actionability as 91.3 %. Most previous studies did not report results from evaluation of the suitability of their patient educational materials [
22‐
24] and thus cannot be compared directly with our findings. However, this is a fairly high score compared with patient evaluations of HF information available through websites [
39]. A recent analysis of 46 websites found that the overall mean understandability was 56.3 %, and the overall mean actionability was 34.7 % [
39]. The PEMAT has excellent measurement properties and is useful in evaluating the quality of educational materials [
36]. Therefore, future researchers should consider evaluating their educational materials from a patient perspective.
There are several limitations that we should consider for the next steps. First, this program was developed for only one tertiary hospital in Korea, which means restriction of the generalizability. To test external validity, more discharge educational program using TBM should be implemented and evaluated as the experimental studies or the quality improvement project at various settings. Second, the outcome measurement for self-care was accounted for on the self-reported questionnaire, so we cannot assume the real change in behaviors. To overcome this limitation, monitoring objective health behaviors using internet of medical things devices could be one way.
Conclusions
The contents of the HEART program were valid, and the educational material was appropriate for both patients and nurses. We expect our structured discharge education program using TBM to enhance the self-management of HF patients. Our study shows how HCPs and researchers can practically develop an intervention program using a methodological model and systematic approach. The detailed phases by which we developed the HEART program illustrate essential elements that HCPs need to consider during implementation. Also, the structure, process, and results of the program designed in this study could guide both research and practice and can be used in settings other than Korea. Finally, the teach-back questions we use to identify gaps between HCPs and HF patients in knowledge, skill, and attitude regarding self-management could be used in clinical practice.
