Model of Hou et al for Prediction of Survival for an HIV-Positive Patient in China Receiving HAART

Description

Hou et al reported a nomogram for predicting survival for an HIV-positive patient in China receiving antiretroviral therapy. The authors are from Wenzhou Medical University and Zhejiang University in China.

Patient selection: HIV-positive patient in China on antiretroviral therapy

Parameters:

(1) CD4 count per microliter

(2) viral load in copies per mL

(3) hemoglobin in g/L

points for CD4 count =

= 100 - (0.111 * (count))

points for hemoglobin =

= 37.4 - (0.106857 * (hemoglobin))

Parameter	Finding	Points
viral load	< 200 copies per mL	0
	200 to 999 copies per mL	20.2
	>= 1,000 copies per mL	52

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 189.4

value of X =

= (-0.000547 * ((score)^2)) + (0.0872597 * (score)) - 0.693078

probability of 3-year survival =

= 1 / (1 + EXP((-1) * X))
