Bold typeface indicates the aggregated indicators.
*Percentage compliance calculated as the number of compliant encounters/number of eligible encounters ×100.
†Compliance and per cent of compliance were not calculated for <30 encounters.

††Enoxaparin 40 mg/day; dalteparin 5000 U/day; LDUH 5000 U two times or three times a day; assumed implicit and explicit risk assessments included.
‡‡One of: ventilation perfusion scan; CT angiography; pulmonary angiography.
§§Heparin administered together with warfarin for at least 5 days; unfractionated heparin intravenous (APTT) or subcutaneous (dose/kg); LMWH subcutaneously at least once daily.
¶¶Compliance for this aggregated indicator was both indicators 43 and 44 were compliant for a participant in an episode of hospitalisation. In other aggregated indicators, compliance was measured by adding each individual encounter as each episode of hospitalisation was an independent event.
APTT, activated partial thromboplastin time; DVT, deep venous thrombosis; INR, international normalised ratio; LDUH, low-dose unfractionated heparin; LMWH, low molecular weight heparin; PE, pulmonary embolism; VTE, venous thromboembolism.
