In providing quality patient outcomes, current evidence based research has to be an important part of this process. With every new research proposal, a solid foundation has to be the basis for that specific research. The following paper is a literature analysis of current studies that support the use of negative pressure wound therapy (NPWT) in healing diabetic foot ulcers in adults. This paper will also discuss what search methods were used, strengths and weaknesses of each study, and the validity and relevancy of the research on the issue of non-healing diabetic foot ulcers in healthcare today. Strategies Used in Literature Analysis This is a literature analysis of evidence based articles that studied the effects of NPWT on people with diabetic …show more content…

(2008) study is of a multicenter RCT comparison of 342 participants with a mean age of 58 and 79% were male. Methods of assessment and tracings were done to monitor the progress of the wound of each participant. The study concluded 73 of 169 participants healed in approximately 96 days by using NPWT whereas, participants without the NPWT took longer or did not heal completely. There was no difference in the healing time if the participant had complications such as infection, cellulitis or osteomyelitis but NPWT was more efficacious than SMWT. There can be some bias as the results are based on a higher count of males than females but the strength of the results support the proposal …show more content…

Each study had a combination of strengths to support the importance of NPWT in healing diabetic foot ulcers. It was also shown that each article was valid, relevant, and peer-reviewed in the support of this need of new methods (NPWT) in improving the patients’ quality of life. The majority of the literature reviewed had a high degree on internal validity through the use of randomized control studies. According to Jarrett (2013), “a high degree of internal validity can be achieved through random control studies because of the decrease in bias that could develop is decreased”. Even though the three systematic reviews supported NPWT, there could possibly be internal threats if the researchers had any personal bias in the selection of studies reviewed. All the articles met the inclusion criteria needed for this proposal. Six studies were excluded due to either being too broad or too inconclusive and could potentially cause errors in the data. Selection bias does not appear to be a factor as the research methods used shows no history of bias in any of the random groups made. Overall, the internal validity is strong. The external validity of this research (NPWT) can be used with all patients’ that have diabetic foot ulcers. Steps were taken to control characteristics that could impact outcomes when considering the sample group such as bias by the
