Risk Score of Kim et al for Post-Hip Fracture Delirium (PHFD)

Description

Kim et al reported a risk score for predicting delirium following surgical repair of a hip fracture. This can help to identify a patient who should be monitored more closely. The authors are from Columbia University in New York City and Hallym University in Seoul.

Patient selection: hip fracture, age >= 60 years

Parameters:

(1) preoperative delirium

(2) preoperative dementia

(3) age in years

(4) medical co-management (medical co-morbidity)

(5) ASA status

(6) functional status

(7) smoking

(8) SIRS, sepsis or septic shock

(9) preoperative use of a mobility aid

Parameter	Finding	Points
preoperative delirium	no	0
	yes	8
preoperative dementia	no	0
	yes	3
age in years	60 to 69 years	0
	70 to 79 years	2
	>= 80 years	3
medical co-management	no	0
	yes	1
ASA status	I or II	0
	III, IV or V	1
functional status	independent	0
	dependent	1
smoking	no	0
	yes	1
SIRS, sepsis, septic shock	no	0
	yes	1
preop mobility aid	no	0
	yes	1

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 20

• The higher the score the greater the risk of delirium.
