Acquisition of sufficient evidence is very crucial towards facilitating the success of a study. In order to promote validity and objectivity in a research activity, it is important that the researchers embrace strategic and procedural engagement of all the facets of medical and scientific research. This includes a standard way through which all the research steps are carried so as to improve the quality of the research activities (Bernd, Prel & Blettner, 2009). Strategic planning and application of research designs are very crucial. Accurate data analysis and application of scientific conceptual frameworks and models are also critical towards the success of the research activity.

In the article ‘Patient Repositioning and Pressure Ulcer Risk-Monitoring Interface Pressures of at Risk Patients’, Peterson et al try to research on the possibility of the patient reposition repositioning eliminating the prevalence of pressure ulcers (Peterson et al, 2013). The authors note that the risk that is presented from pressure ulcers on the bed-ridden is very risky on their health. The authors indicate that pressure ulcers is as a result of excess pressure applied on the subcutaneous layer of the skin. This compromises the flow of blood and thus decreased oxygen supply to the skin. Prolonged pressure applied on a particular spot of the skin leads to the occurrence of the damage on the tissue.

In determining the efficiency of repositioning patients after every two hours- q2h on reduction of pressure ulcers, the researchers conducted an observational study that is descriptive in nature. This was conducted on 170 intermediate and intensive care beds. 23 participants were enrolled in the study from the convenient sampling interval in both the intensive and intermediate patients. Pressure sensors were strategically used to obtain the pressures exerted by the patients against any barriers within the bed. Matlab was used to analyze the data that was collected from the study. 15,784 pressure profiles acquired from 131 h of monitoring was recorded. 14,527 profiles were analyzed from 121 h. this was due to the turning schedule allowances (Peterson et al, 2013). This was also determined across various degrees of elevation.

From the study, there was no significant variance resultant from positions on peak interface pressures in the risk areas. I all the patients that were under investigation, the risk areas exhibited the same risk to the danger of pressure ulcers. The data was also analyzed for interface thresholds of pressure that were more stringent (Peterson et al, 2013). This indicated that more than 83% of the patients were still at risk especially on the risky areas.

From the research, the q2h repositioning model is the standard of healthcare that is implemented to control and mitigate the prevalence of pressure ulcers. This schedule is usually carried out by the nurses in order to enhance proper circulation of blood. However, the method is not very effective as pressure is always experienced at some parts of the body and thus leading to constant danger of ulcers. However, the results also subject the study into other ambiguous interpretations (Peterson et al, 2013). This is because of the deviation of the results that are generated by the censors as a result of the change intervals. This is because the shear movements may be very beneficial because it assist in redistributing weight and thus reducing the risk of infection of pressure ulcers in the parts that are subjected to more risk.

In order to advance this research activity and achieve more objective results, there are various research activities that can be carried out. This research can study how pressure mapping can be applied to enhance better repositioning of patients in order to improve the tissues that are at risk of the tissue pressure. This can assist in complementing the study by advancing better practices that can be used in improving the quality of care through eliminating the areas that are prone to pressure even with the repositioning medical schedule.
