A Quantitative Research Design Critique
The research problem that I have selected in Unit 1 is pressure ulcers. There have been research and studies conducted in order to shed light on this problem. There are research studies that aim to prevent pressure ulcers from happening by implementing interventions. Aside from that, as healthcare professionals, we have to determine the validity of the study. This paper aims to review the research conducted by Bergstrom et al. (2013) in determining the efficacy of the repositioning intervention.
Article Summary
Bergstrom et al. (2013 aimed to “determine optimal repositioning frequency of nursing home (NH) residents at risk for pressure ulcers (PU) when cared for on high-density-density foam mattress” (p. 1705). The study has been conducted in nursing homes located in America and Canada that use high-density foam mattresses for their residents. Bergstrom et al. (2013) implemented three repositioning frequencies as interventions to determine which frequency is best to prevent PUs. The repositioning schedules were 2, 3, or 4 hours for three weeks. The researchers used power analysis to determine the size of their sample, then randomly allocated the repositioning frequencies to the participants who were eligible and where consent was received. In order to maintain the fidelity of the study, the researchers provided on-site training to the NH staff regarding the protocol implementation and documentation, and have maintained communication to
