Aims. To study the use of @entity358 ( @entity358 ) at Hutt Hospital and investigate the use of pretest probability scoring in the assessment of @entity1 with suspected @entity1151 ( @entity1151 ). Methods. We studied @entity1 with suspected @entity1151 that underwent @entity358 between January and May 2012 and collected data on demographics, use of pretest probability scoring, and use of D Dimer and compared our practice with the British @entity1514 Society (BTS) guideline. Results. 105 @entity1 underwent @entity358 and 15% of @entity1 had @entity1151 . 13% of @entity1 had a Wells score prior to their scan. Wells score calculated by researchers revealed 54%, 36%, and 8% @entity1 had low, medium, and high risk pretest probabilities and 8%, 20%, and 50% of these @entity1 had positive scans. D Dimer was performed in 58% of @entity1 and no @entity1 with a negative D Dimer had a @entity1151 . Conclusion. The @entity358 positive rate was similar to other contemporary studies but lower than previous New Zealand studies and some international guidelines. Risk stratification of suspected @entity1151 using Wells score and D Dimer was underutilised. A number of scans could have been safely avoided by using accepted guidelines reducing resources use and improving @entity1 safety.
