Min et al developed a nomogram for predicting complications in geriatric patients with severe trauma. These can help to identify a patient who may require more aggressive management. The authors are from the University of Michigan, VA Ann Arbor Healthcare System, the University of California Los Angeles and the University of California Davis.
Patient selection: adult with severe trauma from 20 to 90 years of age
Pre-existing comorbid conditions:
(1) dementia
(2) cancer
(3) coronary artery disease (CAD)
(4) congestive heart failure (CHF)
(5) pulmonary disease
(6) liver disease
(7) dialysis (kidney disease)
(8) drug use
(9) alcoholism
(10) history of cardiac surgery
(11) coagulopathy
(12) diabetes mellitus
(13) neurologic condition
(14) psychiatric condition
Mortality-Associated Geriatric Complications (MGC) = complications most associated with mortality:
(1) pneumonia
(2) aspiration pneumonia
(3) compartment syndrome
(4) pulmonary embolism
(5) urinary tract infection (UTI)
(6) abscess
(7) fungemia or bacteremia
(8) deep vein thrombosis
(9) pressure ulcer
(10) empyema
(11) wound infection
(10) “failure of wound reduction”
Parameters:
(1) age
(2) number of comorbid conditions
(3) gender
The risk of complications increases as the age and number of comorbid conditions increase.
