Longitudinal patterns and predictors of self-care behavior trajectories among Korean patients with heart failure: A 6-month prospective study

Efficacy of a self-monitoring traffic light diary on outcomes of patients with heart failure: A randomized controlled trial

BACKGROUND AND OBJECTIVE

Patients with heart failure experience high hospitalization. However, patients cannot recognize symptoms according to current approaches, which needs to be improved by new self-monitoring instruments and strategies. Thus, we aimed to assess a self-monitoring traffic light diary on outcomes of patients with heart failure.

METHODS

This was a single-blind, two-arm parallel group randomized controlled trial at the heart failure clinic of Tehran Heart Center (Tehran, Iran). Adult patients with a definitive diagnosis of heart failure with reduced ejection fraction (i.e., ejection fraction of less than 40 %), and New York Heart Association functional classes II-IV were included. A block-balanced randomization method was used to assign eligible subjects to the intervention or control group. Baseline data were collected before random allocation. Participants in the intervention group received a comprehensive intervention consisting of (1) self-care education by an Australian Heart Foundation booklet on heart failure, (2) regular self-monitoring of weight and shortness of breath at home, and (3) scheduled call follow-ups for three months. Patients in the control group received usual care. The primary outcome was heart failure self-care; the secondary outcomes were heart failure quality of life, knowledge, and all-cause hospitalization.

RESULTS

From June to August 2017, 68 patients were included in the study. The overall age of participants was 55 (13.6) years old, and 71 % of patients were male. A significant association between the intervention and self-care maintenance (β 5.1; 95 % CI 2.50 to 7.70, P < 0.001), self-care management (β 10.6; 95 % CI 6.50 to 14.8, P < 0.001), self-care confidence (β 8.0; 95 % CI 5.0 to 11.0, P < 0.001) and heart failure knowledge (β 1.7; 95 % CI 1.30, 2.04; P < 0.001) was found. However, there was no association between the intervention and quality of life (β 2.5; 95 % CI -0.79, 5.88, P 0.135) and hospitalization-free survival of the two groups (Log-Rank P 0.540).

CONCLUSION

A self-monitoring traffic light diary can improve self-care behaviors and heart failure knowledge in patients with heart failure with reduced ejection fraction.

Assessment Tools for Measuring Health Literacy and Digital Health Literacy in a Hospital Setting: A Scoping Review

Assessment of (digital) health literacy in the hospital can raise staff awareness and facilitate tailored communication, leading to improved health outcomes. Assessment tools should ideally address multiple domains of health literacy, fit to the complex hospital context and have a short administration time, to enable routine assessment. This review aims to create an overview of tools for measuring (digital) health literacy in hospitals. A search in Scopus, PubMed, WoS and CINAHL, following PRISMA guidelines, generated 7252 hits; 251 studies were included in which 44 assessment tools were used. Most tools (57%) were self-reported and 27% reported an administration time of <5 min. Almost all tools addressed the domain 'understanding' (98%), followed by 'access' (52%), 'apply' (50%), 'appraise' (32%), 'numeracy' (18%), and 'digital' (18%). Only four tools were frequently used: the Newest Vital Sign (NVS), the Short Test of Functional Health Literacy for Adults ((S)TOFHLA), the Brief Health Literacy Screener (BHLS), and the Health Literacy Questionnaire (HLQ). While the NVS and BHLS have a low administration time, they cover only two domains. HLQ covers the most domains: access, understanding, appraise, and apply. None of these four most frequently used tools measured digital skills. This review can guide health professionals in choosing an instrument that is feasible in their daily practice, and measures the required domains.
