My project was to improve our use of CT pulmonary angiogram, a scan used to check for blood clots in the lungs. I was supported and trained by the Continuous Improvement team to conduct the project. So we looked at the test we were ordering and conducted an audit of how we were using it and why. We formulated a pathway that all the doctors could use to determine whether they need to do the test and measured the before and after of how we were doing it. It turns out that in some cases, we were ordering tests unnecessarily and with the help of the pathway we reduced the number of unnecessary scans, which also reduced the burden on the radiology department who were doing the scans. So as a result of the pathway, we reduced the number of tests by about 20 per cent and increased the positive rate of the test from about 11 per cent to 20 per cent.
