An attempt to study the economic loss arising from Schistosoma japonicum infection and the benefits derived from treatment.

From the northern and southern portions of Leyte Province, which are endemic for schistosomiasis, a total of 801 infected individuals were interviewed, examined, and classified into mild, moderate, severe and very severe forms of disease with an assumed loss of working capacity for each category. The frequency rate or number of spells of illness for the past year under observation were correlated with the degree of incapacity to get the total days lost per person per year. Following a series of computations, of which the disability rate was considered as the most important, a total of 45.4 days lost per infected person per year was arrived at. Treatment of the disease with praziquantel was carried out and the patients were followed up one year after treatment, at which time the same methodology was applied. The results show that the 45.4 days lost prior to treatment went down to 4 days lost. There was an economic gain of 41.4 days as a result of treatment. This can be expressed in terms of financial value if we consider half of the infected cases as breadwinners receiving a minimum wage. It should be noted that a number of assumptions in this study were made. It is, however, hoped that this work will serve as a guide and a starting point for others to carry out related studies on economic loss and subsequent economic benefits to justify budgetary requests/allocations for the implementation of various preventive and control measures.

Evaluation of the losses produced by hydatidosis and cost/benefit analysis of different strategic interventions of control in the province of Rio Negro Argentina

Los programas de control de la hidatidosis requieren de la elaboración de ecuaciones costo/beneficio para la justificación técnica del mantenimiento de su fuente de financiamiento. Así, el objetivo del presente trabajo es analizar los costos para los servicios de salud de la Provincia de Río Negro, Argentina, la atención médica de los casos de hidatidosis humana, evaluar el impacto económico generado por un programa de control y evaluar económicamente alternativas futuras en las estrategias de control. Para ello se obtuvo información de casos humanos atendidos en tres hospitales, tratados con métodos quirúrgicos convencionales, con quimioterapia y con PAIR (punción, aspiración, inyección y respiración), procediéndose a valorizar las prácticas médicas efectuadas. Se estimaron asimismo costos del programa de control basado en la desparasitación de perros y de programas alternativos basados en diagnóstico masivo en personas mediante ecografía y serología y tratamientos no convencionales. Se estimó un costo de tratamiento de US$ 4.511 por paciente, US$ 5.936 en cirugía convencional, US$ 1988 en PAIR y US$ 1.350 en quimioterapia con albendazol. Los costos globales de atención médica para 1997 fueron estimados en US$ 293.215, resultando un 77 por ciento inferiores a 1980. Se estimaron los costos operativos del programa tradicional de control en US$ 440000 y uno alternativo basado en diagnóstico y tratamiento en US$ 260.218. Se analizan relaciones costo/beneficio para cada una de las estrategias planteadas
