Compliance to clinical pathways in the management of suspected pulmonary embolus: are there cost implications?

This study investigated the cost implications of poor compliance to established guidelines for management of suspected pulmonary embolism (PE) in two NSW public hospitals. A retrospective audit showed that the prevalence of PE overall was 9.9% (4.3% in the low-risk groups) in 436 patients. An estimated total of $32 454 (14%) was spent on unnecessary tests.
