PRIMOF Tool of Di Martino et al for Predicting In-Hospital Mortality for a Patient with a Hip Fracture

Description

Di Martino et al reported the PRIMOF tool for predicting in-hospital mortality for a patient with a hip fracture. This can help to identify a patient who may require more aggressive management. The authors are from the University of Chieti-Pescara, "La Sapienza" University of Rome and local health authorities in Italy.

PRIMOF is derived from "Predict In-hospital Mortality of hip Fractured."

Patient selection: hospitalized patient with hip fracture

Parameters:

(1) age in years

(2) sex

(3) cancer

(4) atrial fibrillation

(5) COPD

(6) cerebrovascular disease

(7) ulcer (unspecified if cutaneous or peptic)

(8) kidney disease

(9) heart failure

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 45 (maximum score seen in study 27)

Score	Class	Odds Ratio for Mortality
0 to 3	1	1
4 to 6	2	2.6-3.4
7 to 9	3	5.7-10
> 9	4	24-40

Performance:

• The area under the ROC curve is 0.74.
