ABSTRACT
The rabies is one of the most important officially-known viral zoonotic diseases for its global distribution, outbreak, high human and veterinary costs, and high death rate and causes high economic costs in different countries of the world every year. The rabies is the deadliest disease and if the symptoms break out in a person, one will certainly die. However, the deaths resulting from rabies can be prevented by post-exposure prophylaxis. To do so, in Iran and most of the countries in the world, all the people who are exposed to animal bite receive Post-Exposure Prophylaxis [PEP] treatment. The present survey aimed to investigate the cost-effectiveness of PEP in southern Iran. The present study estimated the PEP costs from the government's Perspective with step-down method for the people exposed to animal bite, estimated the number of DALYs prevented by PEP in the individuals using decision Tree model, and computed the Incremental cost-effectiveness Ratio. The information collected of all reported animal bite cases [n=7111] in Fars Province, who referred rabies registries in urban and rural health centers to receive active care. Performing the PEP program cost estimated 1,052,756.1 USD for one year and the estimated cost for the treatment of each animal bite case and each prevented death was 148.04 and 5945.42 USD, respectively. Likewise 4,509.82 DALYs were prevented in southern Iran in 2011 by PEP program. The incremental cost-effectiveness ratio for each DALY was estimated to be 233.43 USD. In addition to its full effectiveness in prophylaxis from rabies, PEP program saves the financial resources of the society, as well. This study showed performing PEP to be more cost-effective

Objetivando analisar as indicações de profilaxia antirrábica humana no Município de Jaboticabal-SP, foi realizado um estudo retrospectivo descritivo no período de 2000 a 2006, com levantamento de dados registrados nas fichas de investigação de atendimento e cálculo do custo com as vacinas destinadas à profilaxia pós-exposição. Constatou-se que 2.493 pessoas agredidas por animais foram submetidas à profilaxia com uso de vacina, num total de 7.108 doses e um custo de R$ 179.105,14. Da totalidade de casos notificados, 2.184 (71,5 por cento) foram causados por cães e gatos clinicamente sadios no momento da agressão e que assim se mantiveram durante o período de observação, a qual foi feita pela própria vítima ou pelo dono do animal. Considerando este fato e também a situação epidemiológica da raiva no Município, pode-se inferir que essas vítimas poderiam ter sido dispensadas da profilaxia; entretanto, apenas 464 o foram, ou seja, 1.720 pessoas podem ter recebido vacina sem necessidade, ou seja 4.590 doses a um custo de R$ 114.420,81. Em comparação com os números de outros municípios do Estado de São Paulo e com a média nacional, constata-se que o número de profilaxias pós-exposição contra raiva é muito alto em Jaboticabal, evidenciando que na conduta não se considerou o estado do agressor e a condição do Município de área controlada para raiva. Recomenda-se conscientização e capacitação permanentes das equipes de saúde pública quanto à epidemiologia da doença e à necessidade de observação adequada do animal agressor. É essencial a integração dos serviços médicos e veterinários no atendimento às vitimas, visando uma melhor avaliação do caso para que a decisão de se instituir ou não a profilaxia pós-exposição seja feita com critério e segurança.
The present study aimed to evaluate rabies post-exposure prophylaxis (PEP) in humans in the municipality of Jaboticabal, São Paulo from 2000 through 2006. A descriptive and retrospective study was conducted by collecting data available in patient records. Vaccination costs were also calculated; 2,493 patients injured by animals received PEP, totaling R$ 179,105.14 and 7,108 doses; 2,184 (71.5 percent) out of the total reports were caused by dogs and cats clinically healthy at the moment of the attack. These animals remained sound throughout the 10-day observation period. The observation was conducted by the victim or by the owner. Considering animal observation and the epidemiological status of rabies in the municipality, all of these patients could have been dismissed from PEP treatment. Instead, only 464 were dismissed, meaning that 1,720 patients were unnecessarily vaccinated. An estimated 4,590 doses and R$114,420.81 could have been saved. In comparison with rates of other municipalities of the State of São Paulo and with the national mean, the number of PEP in Jaboticabal is very high and it became evident that management evaluated neither the health status of the animal nor the epidemiological status of the area for rabies. Permanent awareness and education of public health professionals with respect to rabies epidemiology and the need to perform correct observation of the aggressors are recommended. It is essential that medical and veterinary services be integrated to provide better assessment of cases and safer decisions on the institution of PEP.
