Costs of pediatric hydrocephalus treatment for the Brazilian public health system in the Northeast of Brazil

To estimate the costs of the surgical treatment of pediatric hydrocephalus, specifically ventriculoperitoneal shunt (VPS) and endoscopic third ventriculostomy (ETV), for the Brazilian public health system (SUS).Retrospective cohort study of health records of patients 14 years of age with a diagnosis of hydrocephalus who underwent VPS or ETV between September 2009 and June 2016, regularly followed up for 24 months.Seventy-six medical records were included. The groups of children who underwent VPS and ETV consisted of 60 and 16 patients, respectively. Complications during 2 years of follow-up were identified in 56% of the children undergoing VPS and in 18% of those undergoing ETV (p = 0.0103). The initial cost of VPS was lower than that of ETV up to approximately 1 year of post-surgical follow-up. After that, VPS generated higher expenses for the SUS due to higher rates of late post-surgical complications and repeated readmissions.Higher public expenditures were observed in the group of children undergoing VPS due to higher rates of infectious and mechanical complications requiring repeated hospitalizations and prosthesis replacements. Public policies must be tailored to offer the best treatment to children with hydrocephalus and to make judicious use of public resources without compromising the quality of treatment.
