Uncertainty in HFrEF Patients

October 16, 2024 updated by: Seyma Demir, Abant Izzet Baysal University

UNCERTAINTY AS a BARRIER to SELF-CARE and QUALITY of LIFE in PATIENTS with HEART FAILURE with REDUCED EJECTION FRACTION

This study was planned as a descriptive and correlational type study to reveal the effect of perceived uncertainty by heart failure (HF) patients with reduced ejection fraction on quality of life and self-care behaviors. In this study, which aimed to reach 122 inpatients with HF, the dependent variables were quality of life and self-care behaviors, the independent variable will be perceived uncertainty. Data will be collected by Mishel Uncertainty in Illness Scale-Community Form (MUIS-C), Left Ventricular Disfunction Scale (LVD-36) and European Heart Failure Self-Care Behavior Scale (EHFSeBS). Data analysis will basically be done with Multivariate Analysis of Variance (MANOVA).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study aims to reveal the effect of perceived uncertainty on quality of life and self-care behaviors in HF patients with reduced ejection fraction. This descriptive and correlational study will include 122 HF patients hospitalized in the cardiology department of a university hospital in northern Turkey. The sample size was calculated according to parameters based on the power of 90%, 95% confidence interval, error level of 0.05, effect size of 0.59. Data will be collected by Mishel Uncertainty in Illness Scale-Community Form (MUIS-C), Left Ventricular Disfunction Scale (LVD-36) and European Heart Failure Self-Care Behavior Scale (EHFSeBS). Data analysis will basically be done with Multivariate Analysis of Variance (MANOVA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • 18 years or older,
  • Having been diagnosed with heart failure by a physician for more than 6 months,
  • Left ventricular ejection fraction <40% as measured by echocardiography,

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Uncertainty (questionnaire)
Time Frame: Baseline
Mishel Uncertainty in Illness Scale-Community Form (MUIS-C) will be used to measure perceived uncertainty. The 20-item Turkish version of the scale has three sub-dimensions: Perception of the current situation (Cronbach's alpha = 0.86), perception of understanding (Cronbach's alpha = 0.78), ambiguity (Cronbach's alpha = 0.79). The total score is obtained by adding the scores given to each item of the five-point Likert scale. Thus, the score that can be obtained from the scale varies between 20 and 100, with an average of 60. An increase in the score obtained from the scale is interpreted as an increase in perceived uncertainty. Cronbach's alpha coefficients calculated in different HF populations using the scale ranged from 0.79 to 0.92, including the Turkish version.
Baseline
Quality of life (questionnaire)
Time Frame: Baseline
Left Ventricule Disfunction Scale (LVD-36) will be used to measure quality of life. The 36-item Turkish version of the scale consists of 36 items and the questions are presented to the patients with two options as true or false. The correct answers given are added together and the total number of correct answers found is expressed as a percentage. Scores between 0 and 100 are taken from the scale, and as the score increases, the quality of life decreases.Cronbach's alpha coefficient of the Turkish version of the scale was calculated as 0.87.
Baseline
Self-care behavior (questionnaire)
Time Frame: Baseline
European Heart Failure Self-Care Behavior Scale (EHFSeBS) will be used to measure self-care behavior. The scale is a 5-point Likert scale consisting of 12 questions that measures the definition of symptoms such as edema, respiratory distress, and fatigue related to HF, regular use of medications for these symptoms, fluid and salt restriction, communication with health personnel, and self-care assessment actions such as weight monitoring. The total score that can be obtained from the scale varies between 12-60. A high total score indicates low self-care, and a low score indicates high self-care. Cronbach's alpha coefficient of the Turkish version of the scale was calculated as 0.69.
