Risk of Death Calculation for APACHE II

• This calculation is used to compute the predicted risk of hospital death for groups of acutely ill patients.

• Our Database Diagnosis Codes are mapped to the Mapping Database Diagnosis Codes to APACHE II but we do not use this model to predict risk of hospital death in our Regional Stat Reports.
• to see the code map marco, refer to: Mapping Database Diagnosis Codes to APACHE II.

• To compute the risk (R) of hospital death for each individual patient we use the following formula:
  • Ln(R/l-R)=3.517+(APACHE II score x 0.146) + (0.603, only if post emergency surgery) + (APACHE II Diagnostic Categories weight)

• • -ve coefficient = good prognosis
  • +ve coefficient = bad prognosis
