Risk-adjusted funnel plot for venous thromboembolism (VTE) prophylaxis administration rates across Burns Registry of Australia and New Zealand units. Factors included in the risk adjustment were: age; gender; the primary cause of the burn; natural logarithm transformation of the percentage total body surface area burned; whether the patient had a full thickness burn; whether the patient had a documented inhalation injury; whether the patient sustained a burn to their leg and/or foot; whether the patient sustained a burn to their chest and/or trunk; and whether the patient was admitted to the intensive care unit. The black line represents the overall risk-adjusted mean VTE prophylaxis administration rate. The grey dashed lines represent the 95% (inner) and 99.8% (outer) control limits. Units beyond the outer control limits are deemed outliers. Unit codes are randomized
