van Walraven Elixhauser score (points)
Band: van Walraven Elixhauser score (points)
Interpretation. van Walraven Elixhauser score (points)
Suggested management. Weighted sum of comorbidity points; higher scores were associated with higher risk of in-hospital death in the derivation data. The paper reports risk on a continuous scale and defines no risk categories. Designed for coded administrative data.
Elixhauser Comorbidity (van Walraven weights): 0 — van Walraven Elixhauser score (points). Interpretation: van Walraven Elixhauser score (points) What to do: Weighted sum of comorbidity points; higher scores were associated with higher risk of in-hospital death in the derivation data. The paper reports risk on a continuous scale and defines no risk categories. Designed for coded administrative data. Inputs: Congestive heart failure (+7): false; Cardiac arrhythmias (+5): false; Valvular disease (−1): false; Pulmonary circulation disorders (+4): false; Peripheral vascular disorders (+2): false; Hypertension, uncomplicated (0): false; Hypertension, complicated (0): false; Paralysis (+7): false; Other neurological disorders (+6): false; Chronic pulmonary disease (+3): false; Diabetes, uncomplicated (0): false; Diabetes, complicated (0): false; Hypothyroidism (0): false; Renal failure (+5): false; Liver disease (+11): false; Peptic ulcer disease excluding bleeding (0): false; AIDS/HIV (0): false; Lymphoma (+9): false; Metastatic cancer (+12): false; Solid tumour without metastasis (+4): false; Rheumatoid arthritis / collagen vascular (0): false; Coagulopathy (+3): false; Obesity (−4): false; Weight loss (+6): false; Fluid and electrolyte disorders (+5): false; Blood loss anaemia (−2): false; Deficiency anemia (−2): false; Alcohol abuse (0): false; Drug abuse (−7): false; Psychoses (0): false; Depression (−3): false Source: van Walraven C, Austin PC, Jennings A, Quan H, Forster AJ. A modification of the Elixhauser comorbidity measures into a point system for hospital death using administrative data. Med Care. 2009;47(6):626-633. DOI: 10.1097/MLR.0b013e31819432e5. PMID: 19433995. Scope: Sum of van Walraven integer weights for the 30 Elixhauser groups (hypertension and diabetes each split into uncomplicated/complicated): CHF +7, cardiac arrhythmias +5, valvular disease −1, pulmonary circulation disorders +4, peripheral vascular disorders +2, hypertension 0, paralysis +7, other neurological disorders +6, chronic pulmonary disease +3, diabetes 0, hypothyroidism 0, renal failure +5, liver disease +11, peptic ulcer disease excluding bleeding 0, AIDS/HIV 0, lymphoma +9, metastatic cancer +12, solid tumour without metastasis +4, rheumatoid arthritis/collagen vascular disease 0, coagulopathy +3, obesity −4, weight loss +6, fluid and electrolyte disorders +5, blood loss anaemia −2, deficiency anaemia −2, alcohol abuse 0, drug abuse −7, psychoses 0, depression −3. Higher totals mean higher risk of in-hospital death; the paper gives no risk categories, so the result is shown as a continuous score. (2009)
