DVT- Deep Vein Thrombosis occurs when a blood clot develops in the thigh muscles or in the veins or calf. This leads to pulmonary embolism in which the clotted blood moves and travels from the legs to the lungs, which is a more serious problem. Pain, redness and swelling in the affected area, fever and joint pain are the DVT symptoms. But sometimes symptoms cannot be found openly. But these are preventable problems that can increase mortality. Early assessment and recognition of risk as well as initiating appropriate prevention measures can prevent DVT or PE. Problem Statement
There is considerable scientific debate as to how great the risk of DVT is from long distance air travel, not moving for a long time – as occurs during long journeys by air, coach or car – is known to be associated with an increased risk of DVT. When someone is sitting down for a long time their blood tends to pool in their lower leg veins causing swelling and increasing the chance that the blood will clot and form a DVT. DVT isn’t something to be alarmed about and maybe less common, but by being aware and taking simple precautions when flying, the risk can be reduced.
Purpose of the study The purpose of this research project is to test a DVT risk assessment tool and verify the tools validity and whether it is reliable or not. Rationale and theoretical base for investigation The approach to test the DVT risk assessment tool can be divided into three phases: The first phase is to perform a through literature survey to investigate and get a clear idea of risk and predisposing factors for DVT. Expert nursing knowledge and medical staff input would be helpful. The second phase is to concentrate on the item development and weighting.
The third phase should measure the differences in mean assessment tool score between two different groups of patients – one group who developed DVT in the hospital and the other group under the same scenario who did not develop DVT. This is measured by parametric testing for content validity. Now, the inter rater reliability should be measured by taking three nurses as a group and each group giving score to one patient and compare the differences in scores of each individual nurse in the group. Derivation of conclusion
If the inter rater reliability showed a strong correlation among the scores of the three nurses, we can conlude that the DVT group had significantly higher scores than did those who did not experience DVT. Nurses can now evaluate patients at risk for DVT or PE. Research Questions How easily this inter rater reliability can be measured? Can the rationale and theoretical base for investigation be enhanced? References Worldviews on Evidence-Based Nursing.
