Researching self-care evidence-based practice is significant in ensuring patients meet their self-care deficit demands. According to Ambrosy et al. (2014), registered heart failure readmissions in the globe account for a total of 26 million individuals. In U.S and Europe, the readmissions were 1 million (Merkow et al., 2015, p.1123). The evidence-based practice of the study formulating education-based intervention for outpatient heart failure health facilities that aim at lowering hospital readmissions.
The sample will include patients that were previously discharged in heart failure clinics and their families. Discharged heart failure patients and their families reflect the population as identified for the purposes of study because they are the most affected stakeholders. Also, families of the patients take nursing roles at home. The sample will be selected using stratified and theoretical sampling techniques. Theoretical sampling focus on collecting a series of data with an aim of developing theory (Etikan, & Bala, 2017, p.2). The technique is appropriate for the study because, in this type of sampling, a research has to have information about the general perspective of the study area and identify key concepts of the research. It allows a high degree of flexibility when determining concepts of a theory because it prevents limiting one-self to a particular concept of an evidence-based practice that results in researchers overlooking other concepts. It involves grouping an entire population into homogenous subgroups deepening on the factors of study. Stratified sampling is appropriate because it reduces sampling errors that lead to improved precision during the study. According to Etikan and Bala (2017), it produces less variability in the study because each stratum selected for the study is mutually exclusive depending on their characteristics or factors of study (p.2). Therefore, stratified and theoretical sampling methods are appropriate for descriptive, meta-analytic, experimental and correlational research design.
The sample size of 70 discharged patients is appropriate because it allows conducting statistical analysis such as t-test and multi-variant regression analysis. Considering that random sampling is used when selecting the population from a particular stratum, the sample size can be used to represent the findings of the entire generalized group. The population size is generalized to Omaha city. The study used analytical generalization whose generalizability is restricted by casual extrapolation on whether the organized variance between control and experimental groups are reinforced by statistical evidence. Also, the degree to which an experiment can be conducted in such a way that the experimental group results can be ascribed to a particular operating cause-driven from EBP intervention limit the generalizability.
The design used was descriptive, meta-analytic, experimental and correlational research design. Combination of the study design flow with the previously discussed parts of the research because it involved trying to lower the increased rate of hospital readmissions of heart failure patients by focusing on developing an EBP that can be proved theoretically. Also, it may help the participants to fulfill self-care deficit.
