Chronic Non-Healing Wound Care
Article
When conducting a research study, you should have a sampling component attached to it, as this is what the research is based on. Gray and Grove (2021), explain the definition of Sampling as the selection of a group of people, events, behaviors, or other elements with which to conduct a study (p.409). There are five components of research sampling, which are the population, target population, Accessible population, sample, and element.
The element component in the population would be referred to as subjects. The population could include everyone in the world who meets the criteria in the study but that would be too vast of a sample group so instead I would focus on a study population. In a study population, it is considered a sample of the target population, this is called the sampling method. (Elfil & Negida,2017).
The main eligibility criteria for my population of interest are that they have a chronic non-healing wound. My picot question involves the correlation between two different dressings in wound care and how they affect healing time. I would have an accessible population-based in either the hospital setting or assisted living facility. Many times, my population of interest is found in hospital settings, outpatient clinics, nursing homes, or patients of a home health agency.
My focus is on selecting patients with hard-to-heal wounds who are willing to participate in the study. I would try and limit the selection to a certain age group and a specific geographical area. By focusing mainly on participants in an inpatient setting there is a higher probability for closer observation and monitor as opposed to participants that are home-based where more external factors can affect the study.

Response
Hi,
I appreciate the information you provided in your initial discussion about how you would carry out sampling when conducting your research. I believe that sampling is a vital research process that has a significant impact on the result. Therefore, I also feel that it is an important topic to discuss to gain a better understanding. In that regard, Elfil & Negida (2017) stated that practical research includes a part of the study population called the sample population.
They defined a population as a group of individuals with a common character or a condition, which in most cases is a disease. The whole population is also called the study population while the sample population is called the study population (Elfil & Negida, 2017). When doing research, it is important to ensure that the sample is representative of the population, as much as possible.
Cash et al. (2022) define both populations as the sample in simple terms; the population is the total set of relevant cases while the sample is a subset of the population. The two major symptoms include probability sampling methods and non-probability sampling methods. In probability sampling, all the subjects in the target population have an equal chance to be selected in the sample (Elfil & Negida, 2017).
In non-probability sampling, the researcher selects the sample population in a non-systematic manner that does not allow equal chances for each one of the subjects. Subtypes of probability sampling include random sampling, stratified random sampling, systematic sampling, and cluster random sampling (Elfil & Negida, 2017). On the other hand, subtypes of non-probability sampling include convenience sampling, judgmental sampling, and snowball sampling.
Cash et al. (2022) provide eight key things to consider when carrying out a sampling process. The first one is scientific ethical concerns. Any research design requires the researcher to balance between scientific and practice concerns. The second consideration is design framing. The five considerations here include theoretical framing, scope, generalization approach, sample schema, and sample size Cash et al. (2022).
In theory development, for instance, the sample is more appropriate if it contributes to knowledge. Another consideration is the cope. A sample of a given population depends on the variable and relationships in focus as well as the planned generalizability and abstraction of the contribution. Others include theoretical framework, generalization approach, sample schema, sample size, and sample strategy Cash et al. (2022). This information is essential when deciding to conduct a study sampling.
