Clinical Trial Summary

Introduction. Heart failure (HF) is the most prevailing chronic illness in the world. In Colombia, high morbidity and mortality rates because of HF are registered, as well as a significant burden of symptoms, frequent hospitalizations, poor quality of life, significant consumption of health resources and early mortality. It is necessary to propose novel strategies that can change the current picture. Objective: determine the efficacy of an intervention centered in decision taking for the handling of symptoms in adults with HF who live in the department of Cordoba, Colombia. Hypothesis Primary hypothesis: the intervention Decision taking for the handling of symptoms in adults with HF: 1) Increases self-care. Secondary hypothesis: 1) reduces clinical events: emergency care and hospitalizations, 3) Improves quality of life related to health.

Clinical Trial Description

Intervention: The theoretic approach of the Theory of the Specific Situation Self-care in HF was used for the design of the intervention. Supplier/dosage/duration. The intervention was given by the researcher (nurse trained in the intervention protocol) in three doses, each contact lasts 60 minutes. Frequency: sessions are given once a week during a one-month period (duration). Nurse controls are implemented after the intervention after one month and three months. There is also telephonic accompaniment on application of the participant. Delivery method/environment. Verbal: Individual face to face. Printed educational written material type brochure, outpatient clinic of a health institution. Methodology Participants: inclusion criteria: adults (over the age of 18 years), more than two months of having been diagnosed; functional New York Heart Association (NYHA) Class II - III, left ventricular ejection fraction reduced (<40%). Cognitive state conservation (Lobo cognitive mini exam - MEC-35). Absence or low co-morbidity (Charlson index). Exclusion criteria: acute HF, advanced HF Sample: The study was designed to have a 90% output, (alpha = 0.05), an expected difference of 0.5 in the outcome score of the management and maintenance evaluation in both groups, a standard deviation of outcome scores of 1.0, a correlation average between the first and the second evaluation of 0.2 and a rate of wear of 20%. Therefore, the required final sample size was 124 (62 per group - theoretic sample). Pilot study: 176 adults with HF were recruited. 114 entered the study. 62 were excluded (did not meet the inclusion criteria (n=39), did not want to participate (=14), other reasons (n=9)). Randomization. Table of random numbers without repetition. The Participants randomly assigned to the control group CG (n=57) received the standard attention, including standard education given by attention providers, and the ones assigned to the intervention group IG (n=57) received the intervention protocol. Information collection (research assistant). The study registers information in the following time points: beginning (base line), follow up after a month (outpatient appointment), follow up after 3 months (outpatient appointment). The study is classified as simple blind; the research assistant, who is in charge of applying the instrument measuring the effect of the intervention, will remain blinded during the whole study regarding the group assigned to each participant. Risk control. Compliance with methodological recommendations used to guarantee reliability and validity of the research studies proving a clinic intervention for behavioral changes. A plan is being contemplated that includes goals and strategies to monitor and counter possible threats to internal and external validity. Ethical aspects. Compliance with universal ethical principles for research on humans, according to international ethical guidelines - CIOMS, national regulations, informed consent and deontological Nursing responsibilities in Colombia. Analysis framework Excel database - SPSS Program analysis 1. Descriptive analysis of the total sample and by groups (intervention and control): absolute and relative frequency distributions; median and standard deviation. 2. Data normality analysis: Kolmogorov-Smirnov test Statistical analysis for independent samples a) difference of proportions: X2, b) difference of means: t for student, c) difference of medians: U test of Mann - Whitney. In all cases a statistic significance will be assumed if the value p < 0.05. 3. Intrasubject and intergroup analysis: ANOVA with repeated measurements. 4. Hypothesis proof: W of Mauchly test. When the sphericity premise is fulfilled, test F will be used. 5. Analysis of possible confusion and/or interaction effect. 1. Stratified analysis: X2 of Mantel-Haenszel (M-H), 2. Logistic regression analysis. Stepwise method. Minimum change % considered as favorable (≥20=1, ≤19=0). 6. Analysis of the magnitude of the intervention's effect. Improvement of at least 20% of the score on the scale, with the analysis principle of the intention of trying. The absolute increase in benefit and the necessary number for treatment (NNT) will be calculated afterwards. ;
