Disposição para pagar uma intervenção para melhorar o controlo da hipertensão em hipertensos não controlados : um estudo-piloto

RESUMO - A valorização económica de intervenções preventivas pode contribuir para melhorar a afetação de recursos em saúde. A hipertensão, primeira causa de morte em Portugal, é um grave problema de saúde Pública e o principal fator de risco para a ocorrência de Acidente Vascular Cerebral (AVC). O presente estudo é um primeiro ensaio para quantificar a disposição para pagar (DPP) da sociedade por uma intervenção de promoção da adesão à terapêutica em hipertensos não controlados. Foi aplicado um questionário presencial a uma amostra de conveniência (n=93), numa perspetiva ex post, sendo o questionário constituído por dois formatos de questões e dois cenários de diferentes reduções de pressão arterial sistólica (cenário 1 corresponde à redução de 10 mmHg e cenário 2 à redução de 20 mmHg). O risco de AVC a 10 anos foi adaptado à idade e ao sexo de cada participante. Relativamente ao cenário 1, a DPP média foi de €25,87 e €33,93, dependendo do formato da questão (resposta aberta ou bidding game, respetivamente). Na questão de resposta aberta, 78,3% dos participantes estavam dispostos para pagar pela intervenção, no bidding game 75,6% dos participantes referiram estar dispostos para pagar pelo menos €10. No cenário 2, a DPP média foi de €26,81 e €34,79, dependendo se o formato da questão era do tipo resposta aberta ou bidding game, respetivamente. Na questão de resposta aberta, 84,3% dos participantes estavam dispostos para pagar pela intervenção, no bidding game 76,1% dos participantes referiram estar dispostos para pagar pelo menos €10. Ao contrário do bidding game, nas questões de resposta aberta verificou-se 25,8% e 24,7% de respostas “não sei”, para o cenário 1 e cenário 2 respetivamente, diretamente relacionada com a baixa escolaridade dos participantes (p=0,004). Também se verificou uma maior tendência para respostas às questões de bidding game com valores mais elevados, comparativamente às questões de resposta aberta. Identificaram-se duas variáveis explicativas para os valores DPP: o rendimento e a ocupação principal. A sensibilidade dos respondentes à magnitude dos ganhos em saúde foi verificada internamente em cada questionário (os participantes referiram DPP mais elevadas no cenário 2 relativamente ao cenário 1), no entanto, os participantes que beneficiariam mais da intervenção não demonstraram DPP superiores aos restantes. Para confirmar os efeitos identificados neste estudo e extrapolá-los para a população portuguesa é necessário realizar um estudo representativo de população portuguesa.

Environmental contamination by Toxocara sp eggs in public areas of Salvador, Bahia state, Brazil

A survey ofparasite eggs and cysts in soil and dog feces collected in public places of 23 boroughs of Salvador, a city in the Northeast of Brazil, was performed. High degree of contamination by Toxocara sp eggs was observed in all boroughs studied; other parasites found included: Ascaris lumbricoides, hookworms, whipworms and protozoan cysts. Parks andpublic gardens were more contaminated than streets and beachesfor all parasites, including Toxocara sp.

Re-evaluation of the basic procedures involved in the storage of measles vaccine in public health units of the municipality of Niterói, state of Rio de Janeiro, Brazil

Four years after the first visit seventeen public health units were visited again and evaluated as to standards of storage recommended by the Brazilian Immunization Programme. In 100% of the units, refrigerators and proper inside location of vaccines in the refrigerator were adequatety or regularfy maintained and checked, respectively. However, when control of temperature was checked, onfy 64.7% presented adequate storage conditions. In 94.1 % of the units, health workers complained of lack of immediate technical support in emergency situations. In 55.2 % the titers vaccine samples of were under the minimal recommended potency. It is necessary that the factors concerning the cold chain be continualfy evaluated so that the quality of the vaccines that will be used is not affected.

Directed Giving: Evidence from an Inter-Household Transfer Experiment*

We investigate the determinants of giving in a lab-in-the-field experiment with large stakes. Study participants in urban Mozambique play dictator games where their counterpart is the closest person to them outside their household. Dictators share more with counterparts when they have the option of giving in kind (in the form of goods), compared to giving that must be in cash. Qualitative post-experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources. Standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving, but the effects of even large changes in these determinants are significantly smaller than the effect of the in-kind option. Our results support theories of giving where the utility of givers depends on the composition (not just the level) of gift-recipient expenditures, and givers thus seek control over transferred resources.

Public funding of higher education: who gains, who loses?

This paper analyses the effects of public funding of higher education on the welfare of the different agents. It takes into account the hierarchical nature of the educational system and also the fact that parents always have the possibility to complement basic public education with private expenditures in individual tutoring. It is obtained that although public funding implies a larger access to higher education it is always the case that some of the agents that gain access lose in welfare terms. Moreover, it is shown that the marginal agent to access university would always prefer a pure private funding system. Thus, when studying the effects of public funding of higher education, we can not identify gaining access to University with an increase in welfare. Finally, I consider a funding system where only those that send their o¤spring to university support the funding of higher education.
