BackgroundThe Glasgow coma scale (GCS) is an objective measurement of a patient's level of consciousness and has prognostic implications in traumatic head injuries. Morbidity and mortality of patients with meningitis have been related amongst others to level of consciousness, hypoglycorrhachia, extremes of age, and high CSF protein values. In this prospective study of 100 patients the correlation between the GCS, age, CSF-neutrophil count and CSF-glucose and protein levels and the eventual outcome of the patients was assessed.MethodsIn 100 consecutive patients with meningitis (bacterial, viral, tuberculous, cryptococcal and other) the GCS, age, CSF-neutrophil count and CSF-protein and glucose levels were determined at admission. After treatment the outcome of the patient was assigned to one of four categories: healthy, minor and severe neurological deficits and death.ResultsFrom a non-parametric one-way analysis of variance it was found that with respect to mean GCS-values significant differences were present among the outcome categories (P < 0.0001). The outcome categories did not differ significantly with respect to age, CSF-neutrophil count or CSF-glucose level, but did differ significantly with respect to the CSF-protein level (P < 0.0025). Additionally, 88% of patients with a GCS value of > 12 had a good neurological outcome, while 88% of those with a GCS value of < or = 8 had a poor outcome.ConclusionA good correlation between both the GCS and CSF-protein level at admission and the outcome of patients with meningitis was found, with the GCS value being a better prognostic indicator than high CSF protein levels.
