Research design lays out strategies to apply to answer questions that establish a relationship between cause and effect. Through quantitative research, improvements in health care can occur through various research methods. Such methods allow for improved patient outcomes, increased safety and prevention methods. Also, quantitative findings are useful for allowing anticipation of problems and evidence-based solutions to occur. Overall, allowing a better patient experience. An example of a quantitative research design is DVT Prophylaxis during procedural times to increase patient safety, from complications of DVT/PE. The use of VTE prophylaxis during procedure times has proven to decrease complications/death of a patient and cut health care costs. The surgical population can be trended with observing reduction in complications of post op DVT/PE, after the use of VTE Prophylaxis intraprocedural. Mechanical compression has become a common form of prevention against the formation of clots during a procedure. Through quantitative research, strategies were applied to aid in the prevention of post op complications for the patient. In regard to this topic. Through education, compliance, and monitoring of staff, decreased complications occurred for patients. The results could be measured in comparing occurrence of DVT/PE in patients post op before compliance of prophylactic strategies used and the results after compliance of use.

To determine if a change has been effective the results obtained need to be measured against something. The numbers/information altered need to be compared to numbers/information prior to the change being implemented. This is why quantitative research is extremely helpful. It “generates numerical data and usually seeks to establish causal relationships between two or more variables, using statistical methods to test the strength and significance of the relationships” (Finding Quantitative or Qualitative Nursing Research Articles: Helpful Definitions, 2019, p.1). This type of research allows allows for results analyzed for effectiveness and identify areas requiring improvement.

One study that I found which utilizes quantitative research approach focuses on the issue of patient falls. Over the past six decades there have been numerous studies conducted on how to prevent patient falls. Despite efforts to improve safety measures “there has been an increase (estimated to be 46% per 1000 patient days from 1954–6 to 2006–10) in the number of patient falls in hospitals and other health care facilities” (Weil, 2015, p. 342). This study looked at patient fall rates at several different hospitals over the period of six decades. After analysis of patient admission records, incident reports, and hospital expenses related to patient fall injuries this study concluded that incidence of patient falls has increased. The study offers several suggestions for contributing factors such as medication, comorbidities, nurse patient ratio, location of falls, and age. While the author states that further research needs to be done addressing these issues more closely the overall incidence of patient falls continues to increase despite heightened awareness and improved safety precautions. “Reported was a mean fall rate of 3.65 per 1000 patient days during a 54-month period (July 2006–December 2010) in a longitudinal study with a sample of 1524 hospitals participating in a National Database for Nursing Quality endeavor” (Weil, 2015, p.343).  This study shows that this issue needs to be further addressed. Despite all the improvements health car facilities have made they have a long way to go in protecting their patients from falls.
