Resumen
Introduction: Malignant hyperthermia is an acute syndrome
triggered by certain anesthetic medications. Dantrolene is the
only specific treatment for malignant hyperthermia crises.
Without treatment, lethalitymay be as high as 80%. In Colombia,
it is not mandatory to keep dantrolene supplies in stock. Objective: To establish the cost-benefit ratio, from the
perspective of healthcare institutions, of keeping dantrolene
supplies in stock in the operating theater.
Methods: Using a decision tree, a Monte Carlo simulation was
run with 10 thousand scenarios to determine the median annual
cost of keeping full or partial stocks (36 or 12 vials 20mg,
respectively) of dantrolene. For the option of not keeping supplies
in stock, the cost threshold was calculated where the expected
value of both alternatives of the decision tree is equalized.
Indifference curves were constructed for complete and partial
supplies.
Results: The median annual cost was estimated at 6.6 million
Colombian pesos (COP) for full dantrolene supplies, and at COP 2.2
million for partial supplies. The median economic consequence
threshold for one death due to the unavailability of dantrolene
was estimated at COP 18.5 million for full supplies, and at COP 57.0
million for partial supplies.
Conclusion: If, as a result of the unavailability of dantrolene,
the economic consequences of a death due to malignant
hyperthermia exceed the threshold of COP 57.0 or COP 18.5 million,
the purchase of full or partial stocks, respectively, is justified. Introduccion: La hipertermia maligna (HM) es un síndrome agudo
desencadenado por algunos medicamentos anestésicos. El
dantroleno es el unico tratamiento especí fico para las crisis de
HM. Sin tratamiento puede tener una letalidad cercana al 80%. En
Colombia, el abastecimiento de dantroleno no es obligatorio.
Objetivo: Establecer la relacion costo-efectividad, desde el
punto de vista de las instituciones prestadoras de servicios
de salud, de mantener un abastecimiento de dantroleno en
quirofanos.
Métodos: Mediante un árbol de decisiones se realizo una
simulacion Monte Carlo con 10 mil escenarios para determinar la
mediana del costo anual de un abastecimiento completo o parcial
(36 o 12 viales de 20mg, respectivamente) de dantroleno. Para la
alternativa de no tener abastecimiento, se calculo el umbral de
costo, donde se iguala el valor esperado de ambas alternativas del
árbol de decisiones. Se construyeron curvas de indiferencia para
el abastecimiento completo y parcial.
Resultados: La mediana del costo anual del abastecimiento
completo de dantroleno se estimo en $6.6 millones de
pesos colombianos (COP), y el del abastecimiento parcial en
$2.2 millones COP. La mediana del umbral de consecuencias
economicas por una muerte sin disponibilidad de dantroleno se
estimo en 18.5 millones COP para el abastecimiento completo, y
en 57.0 millones COP para el abastecimiento parcial.
Conclusion: Si por no disponer de dantroleno las
consecuencias economicas de una muerte por HM superan el
umbral de $57.0 o $18.5 millones COP, se justifica la compra de un
abastecimiento completo o parcial, respectivamente.
