Pre-Existing Conditions (PEC) of Morris et al Affecting Mortality in Trauma Patients

 

Comorbid conditions with major increase in mortality:

(1) cirrhosis (relative odds 4.5)

(2) hereditary coagulation disorder (relative odds 3.2)

 

Comorbid conditions with some increase in mortality (relative odds 1.2 to 1.8):

(3) ischemic heart disease

(4) chronic obstructive pulmonary disease (COPD)

(5) diabetes mellitus

 

Situations where impact of PEC is greatest:

(1) adult 25 - 64 years of age (maximal from 45-54) with injury of any severity

(2) injuries of mild to moderate severity (ISS < 13)

 

where:

• In the implementation I assigned 3 points to cirrhosis, 2 to coagulopathy and 1 for the remaining 3 PEC.

• In the implementation have also experimented with a "PEC score" based on combining the SUM of the points assigned to the pre-existing conditions (maximal score 8) plus the number of situations with increased PEC impact (maximal 2). This would apply if there was 1 or more PEC).
