A cost-effectiveness analysis of endoscopic third ventriculostomy.

Area of Science:

• Neurosurgery
• Pediatric Hydrocephalus Management
• Health Economics

Background:

• Endoscopic third ventriculostomy (ETV) is a primary alternative to cerebrospinal fluid (CSF) shunts for pediatric hydrocephalus.
• Cost-effectiveness analysis is crucial for optimizing treatment strategies.
• This study compares ETV with CSF shunts in pediatric hydrocephalus management.

Purpose of the Study:

• To conduct a cost-effectiveness analysis of ETV versus CSF shunt placement in pediatric hydrocephalus.
• To evaluate resource consumption and treatment outcomes for both procedures.

Main Methods:

• Retrospective analysis of 28 pediatric patients undergoing ETV between 1989-1998.
• Patients were matched with CSF shunt recipients based on age, pathogenesis, and prior procedures.
• Hydrocephalus-related resource use and treatment-free days were assessed; costs were linked to resource use and discounted.

Main Results:

• ETV success rate was 54% (defined by reoperation); one death and one hemiparesis occurred in the ETV group.
• Shunt group had no permanent procedure-related morbidity/mortality but incurred additional resource use (6 readmissions, 8 reoperations).
• Mean costs were similar ($10,570 ETV vs. $10,922 shunt); ETV provided an additional 86 treatment-free days, but differences were not statistically significant.

Conclusions:

• In this cohort, ETV was not significantly more cost-effective or effective than shunts over a median 35-month follow-up.
• The observed success rate of 54% for ETV, coupled with additional morbidity/mortality, did not demonstrate clear advantages.
• Larger cohorts, longer follow-up, or improved ETV success rates are necessary to establish its cost-effectiveness.
