General / Multi-Specialty A
Elixhauser Comorbidity Index
van Walraven point version of the Elixhauser comorbidity measures (21 of 30 conditions carry weight). Designed for in-hospital mortality risk adjustment of administrative data.
Score interpretation
van Walraven Elixhauser Score -19–89
Higher scores mean higher in-hospital mortality (c-statistic 0.76, van Walraven 2009). There are no validated low / moderate / high cut-offs; negative weights reflect coding associations, not protection.
→ Use for risk adjustment of groups and research, not for individual treatment decisions.
