Model of Phusoongnern et al for a Permanent CSF Shunt for a Patient with Cryptococcal Meningitis

Patient selection: cryptococcal meningitis

Outcome: placement of a permanent CSF shunt

Parameters:

(1) hydrocephalus

(2) initial cerebrospinal fluid opening pressure in cm H2O

(3) HIV status

X =

= SUM(points for all 3 parameters) - 3.85

probability of permanent CSF shunt =

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