Analysis of direct costs of decompressive craniectomy in victims of traumatic brain injury

ABSTRACT

Background: Decompressive craniectomy is a procedure required in some cases of traumatic brain injury (TBI). This manuscript evaluates the direct costs and outcomes of decompressive craniectomy for TBI in a developing country and describes the epidemiological profile.

Methods: A retrospective study was performed using a five-year neurosurgical database, taking a sample of patients with TBI who underwent decompressive craniectomy. Several variables were considered and a formula was developed for calculating the total cost.

Results: Most patients had multiple brain lesions and the majority (69.0%) developed an infectious complication. The general mortality index was 68.8%. The total cost was R$ 2,116,960.22 (US$ 661,550.06) and the mean patient cost was R$ 66,155.00 (US$ 20,673.44).

Conclusions: Decompressive craniectomy for TBI is an expensive procedure that is also associated with high morbidity and mortality. This was the first study performed in a developing country that aimed to evaluate the direct costs. Prevention measures should be a priority.

RESUMO

Introdução: A craniectomia descompressiva (CD) é procedimento necessário em alguns casos de trauma cranioencefálico (TCE). Este manuscrito objetiva avaliar os custos diretos e desfechos da CD no TCE em um país em desenvolvimento e descrever o perfil epidemiológico.

Métodos: Estudo retrospectivo foi realizado usando banco de dados neurocirúrgico de cinco anos, considerando amostra de pacientes com TCE que realizaram CD. Algumas variáveis foram analisadas e foi desenvolvida uma fórmula para cálculo do custo total.

Resultados: A maioria dos pacientes teve múltiplas lesões intracranianas, sendo que 69.0% evoluíram com algum tipo de complicação infecciosa. A taxa de mortalidade foi de 68,8%. O custo total foi R$ 2.116.960,22 (US$ 653,216.00) e o custo médio por paciente foi R$ 66.155,00 (US$ 20,415.00).

Conclusões: CD no TCE é um procedimento caro e associado á alta morbidade e mortalidade. Este foi o primeiro estudo realizado em um país em desenvolvimento com o objetivo de avaliar os custos diretos. Medidas de prevenção devem ser priorizadas.
