Outpatient Surgery Admission Index - Medical Algorithm

Description

Fleisher et al developed the Outpatient Surgery Admission Index (OSAI) that can help identify a patient who may need to be admitted to the hospital immediately after an outpatient procedure. The authors are from the University of Pennsylvania, University of Cincinnati, the Johns Hopkins University and the University of Baltimore.

Parameters:

(1) age of the patient

(2) length of the procedure in minutes

(3) cardiac disease

(4) peripheral vascular disease

(5) cerebrovascular disease

(6) malignancy

(7) HIV seropositivity

(8) type of anesthesia

Parameter	Finding	Points
age of the patient	< 65 years	0
	>= 65 years	1
length of procedure	<= 120 minutes	0
	> 120 minutes	1
cardiac disease	absent	0
	present	1
peripheral vascular disease	absent	0
	present	1
cerebrovascular disease	absent	0
	present	1
malignancy	absent	0
	present	1
HIV seropositivity	absent	0
	present	1
type of anesthesia	none	0
	regional	1
	general	2

where:

• Pulmonary disease like COPD is not listed as a risk factor.

OSAI =

= SUM(points for all 8 parameters)

Interpretation:

• minimum score: 0

• maximum score: 9

• The higher the score the greater the risk of being admitted to the hospital immediately after the outpatient surgery.

• The maximum score reported in Table 3 is 6.

OSAI	Risk of Being Hospitalized
0 or 1	very low
2	low to moderate
3	moderate
4, 5 or 6	high
7, 8 or 9	very high
