OBJECTIVE: To determine the clinical effectiveness and cost-effectiveness of testing for and empirically treating herpes simplex virus (HSV) infection in neonates with fever aged from birth to 28 days. DESIGN: Cost-effectiveness analysis. SETTING: Decision model. PATIENTS: Neonates with fever with no other symptoms and neonates with fever with cerebrospinal fluid (CSF) pleocytosis. INTERVENTIONS: Four clinical strategies: (1) HSV testing and empirical treatment while awaiting test results; (2) HSV testing and treatment if test results were positive for HSV or the patient had symptoms of HSV; (3) treatment alone without testing; or (4) no HSV testing or treatment unless the patient exhibited symptoms. The 2 HSV testing methods used were CSF HSV polymerase chain reaction (PCR) and comprehensive evaluation with blood HSV PCR, CSF HSV PCR, and multiple viral cultures. MAIN OUTCOME MEASURES: Twelve-month survival and quality-adjusted life expectancy with a cost-effectiveness threshold of $100,000 per quality-adjusted life year (QALY) gained. RESULTS: Clinical strategy 1, when applied in febrile neonates with CSF pleocytosis, saved 17 lives per 10,000 neonates and was cost-effective using CSF HSV PCR testing ($55,652/QALY gained). The cost-effectiveness of applying clinical strategy 1 in all febrile neonates depended on the cost of the CSF HSV PCR, prevalence of disease, and parental preferences for neurodevelopmental outcomes. Clinical strategies using comprehensive HSV testing were not cost-effective in febrile neonates ($368,411/QALY gained) or febrile neonates with CSF pleocytosis ($110,190/QALY gained). CONCLUSIONS: Testing with CSF HSV PCR and empirically treating with acyclovir sodium saves lives and is cost-effective in febrile neonates with CSF pleocytosis. It is not a cost-effective use of health care resources in all febrile neonates.
