Variation in the incidence and timing of diagnosis of hospital‐associated venous thromboembolism using linked administrative data
Venous thromboembolism (VTE) is a potentially preventable adverse effect of hospitalisation. Inter‐hospital variation in the incidence of hospital‐associated VTE (HA‐VTE) and timing of diagnosis (in‐hospital or post‐discharge) in New South Wales public hospitals were examined. Large variations in incidence (22% risk difference) and post‐discharge diagnosis (115% odds difference) were evident after adjustment for case mix, which only explained 59% and 32% of inter‐hospital variation respectively. The need for improved compliance with best practice guidelines is reinforced.
