PICOT Question: In the critically ill elderly patients, does nurses knowledge of evidence-based recommendations for pressure ulcer prevention affect the incidence and prevalence of pressure ulcers?
General Description of Study
Overview of Study
Purpose of Study
The purpose of the study was to find out how a planned intervention applying the evidence-based pressure ulcer prevention would affect important aspects of pressure ulcer care. These aspects of pressure ulcer management include; the practice of pressure ulcer prevention and the nursesâ€™ knowledge of the updated evidence based pressure ulcer prevention recommendations. The above aspects of care influence the prevalence of pressure ulcer that was also the aim of the researchers in this study (Sving, Hogman, Mamhidir&Gunningberg, 2014).
The researchers employed a quasi-experimental research design. This methodology is sometimes referred to as pre-post-intervention design because it involved testing before and after intervention (pre- and post-testing) during data collection. The study under review involved testing nursesâ€™ level of knowledge about evidence-based pressure ulcer prevention strategies, in addition, the researchers established baseline data regarding pressure ulcer prevention and noting the prevalence of pressure ulcers before testing. Following the establishment of the baseline data (pre-testing), the researchers executed the planned intervention i.e. multi-faceted unit-tailored intervention (Sving, Hogman, Mamhidir& Gunningberg, 2014 p.1). The post-testing involved testing the resultant nursesâ€™ knowledge of pressure ulcer prevention as well as observing how pressure ulcer prevention changed in the hospital units and the prevalence of pressure ulcers.
It should be noted that both patients and nurses were participated in the intervention. All patientsof aged â‰¥ 18 years admitted in the units under study were eligible. Although only 145 nurses participated, all nurses working in the units under study were eligible. The study therefore adequately employed the quasi-experimental study design. This research approach has exhibited substantial importance in the field of clinical research especially where the pursuit of complete randomised (pure experimental) is unethical or unfeasible (Eliopoulos et al., 2004).
From the purpose of the study, it can be deducted that the researchersâ€™ main hypothesis was that the multi-faceted intervention applying evidence-based pressure ulcer recommendations enhanced the practice of pressure ulcer prevention. The researchers categorically stated that pressure ulcer prevention was their main area of interest (Sving, Hogman, Mamhidir&Gunningberg, 2014 p.2). The following research questions can then be derived from this hypothesis;
* How does a multi-faceted unit-tailored intervention using evidence-based recommendations affect the performance of pressure ulcer prevention?
* What is the effect of the intervention on the knowledge and attitudes of nurses on recommended pressure ulcer prevention strategies?
* The last question that the researchers aimed at answering was how the intervention affected the prevalence of pressure ulcers.
The aim of the study was to evaluate, through pre- and post-intervention testing, the effect of a applying updated pressure ulcer prevention recommendations on the practice of pressure ulcer prevention, prevalence of pressure ulcers and the knowledge and attitudes of nurses on pressure ulcer prevention strategies (Sving, Hogman, Mamhidir&Gunningberg, 2014).
The method of sampling employed can be categorised as simple random sampling because each nurse in the selected units had an equal chance of participating in the study. This also applied to the patients who participated in the study. The sample size for the nurses during pre-test was 145 out of 149 (97%) while at post-test those who participated were 130 out of 169 (76%). The sample size for the patients during pre-test was appropriate at 251 out of 304 (82%) while at post-test was 255 out of 312 (81%)(Sving, Hogman, Mamhidir & Gunningberg, 2014).
According to (Dereshiwsky, 1998), study variables refer to specific characteristics that can change through manipulation. Also according to (Dereshiwsky, 1998) these variables of a study can be classified to dependent, independent, extraneous and confounding variables. The dependent and independent variables are the major variables of the study. In this study by Sving and colleagues (2014) the use of evidence-based pressure ulcer recommendation (Multi-faceted intervention) is the independent variable because the independent variable refers to what the researcher is manipulating or the variable that the researcher has control over (Dereshiwsky, 1998).
The dependent variable can be simply defined as the characteristics that the researcher is measuring. In other words, the aspects of the study the researcher expects to change after manipulation of the independent variable. Therefore, from the study under appraisal t...
