Sense of Security Mediates the Relationship Between Self-care Behavior and Health Status of Patients With Heart...

Promoting patients' sense of security is among the goals of nursing care within heart failure management.

The aim of this study was to examine the role of sense of security in the relationship between self-care behavior and health status of patients with heart failure.

Patients recruited from a heart failure clinic in Iceland answered a questionnaire about their self-care (European Heart Failure Self-care Behavior Scale; possible scores, 0-100), their sense of security (Sense of Security in Care-Patients' Evaluation; possible scores, 1-100), and their health status (Kansas City Cardiomyopathy Questionnaire, including symptoms, physical limitations, quality of life, social limitations, and self-efficacy domains; possible scores, 0-100). Clinical data were extracted from electronic patient records. Regression analysis was used to examine the mediation effect of sense of security on the relationship between self-care and health status.

The patients (N = 220; mean [SD] age, 73.6 [13.8] years; 70% male, 49% in New York Heart Association functional class III) reported a high sense of security (mean [SD], 83.2 [15.2]) and inadequate self-care (mean [SD], 57.2 [22.0]); their health status, as assessed by all domains of the Kansas City Cardiomyopathy Questionnaire, was fair to good except for self-efficacy, which was good to excellent. Self-care was associated with health status ( P < .01) and sense of security ( P < .001). Regression analysis confirmed the mediating effect of sense of security on the relationship between self-care and health status.

Sense of security in patients with heart failure is an important part of daily life and contributes to better health status. Heart failure management should not only support self-care but also aim to strengthen sense of security through positive care interaction (provider-patient communication) and the promotion of patients' self-efficacy, and by facilitating access to care.
