I would choose the stratified sampling method for studies like this, which allows to represent the population on a smaller scale. The population is conveniently divided by several characteristics: gender, social class, level of education, and religion (Moser & Korstjens, 2018). It is then important to sample within each category to obtain the necessary subsets from the sets used in the HAC study. This method can minimize the disadvantages of random sampling through division into different categories followed by selection, thereby guaranteeing broad representation. Stratified selection will better characterize the response to surgical site infections.
The necessary data should collect for further study from the selected participants. The focus group formation method should use to obtain relevant comments to achieve this goal. The free-focus group discussion allows for a better understanding of the problems faced by each of the representatives of the original groups (Moser & Korstjens, 2018). One of the significant advantages of this method is its speed, ease, and minimal cost. However, opinions can be quite subjective due to the presence of other representatives, who will not want to talk about some things. An ethical problem that can be solved by more careful selection at the initial stage will make people feel more comfortable and open when it comes to the HAC directly.
I believe that these sampling and information collection methods make the study more representative and relevant to the majority of the population. The methods are valid and reliable because they cover the general population equally and under the same conditions. The measurements are more accurate and relevant to our days to make a fair assessment of the problems associated with surgical site infections. It is essential to choose the right research strategies to detect timely errors that can quickly be corrected in medical matters.
