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 APACHE II Diagnostic Categories 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
