[Cost analysis of early diagnosis of hydatidosis in children of 5 and 12 years old in the province of Ñuble, Bío-Bío Region, Chile].
This study conducted a cost analysis of different interventions in the early diagnosis of hydatidosis between the years 2006 -2007 in the Province of Nuble, Bio-Bio Region of Chile. The aim was to estimate the costs of early diagnosis of this condition. We included all children of 5 and 12 years old in rural areas of the province. Data collection activities were identified which included specific antibody measurements (indirect ELISA) and an abdominal ultrasound. For the determination of costs, direct and indirect costs were identified using the methodology of activity-based costs. The results demonstrate that the preventive diagnosis costs S17.183 Chilean pesos per child (S35 US dollars), thus making this intervention of lower cost than waiting until the person becomes ill with this disease.
