Cancelamentos de cirurgias no próprio dia

RESUMO - INTRODUÇÃO: Para garantir a qualidade e universalidade dos cuidados de Saúde, é fundamental, que os recursos disponíveis sejam bem utilizados, evitando desperdícios. Os resultados de um hospital estão diretamente ligados aos resultados do Bloco Operatório. A taxa de utilização e a taxa de cancelamentos são indicadores da atividade dos Blocos Operatórios. Realizou-se um estudo piloto no Hospital Dr. José de Almeida em Cascais. OBJECTIVO: Conhecer as taxas de cancelamento de cirurgias no próprio dia. METODOLOGIA: Estudo descritivo longitudinal, retrospectivo, quantitativo, às cirurgias agendadas, entre 1 de Janeiro e 31 de Março de 2012. Utilizou-se a estatística descritiva e a inferência estatística através de testes de independência de variáveis. RESULTADOS: 1524 cirurgias agendadas, canceladas 205, com 100 cancelamentos no próprio dia. Os resultados revelam na globalidade taxas de cancelamento (13,45%) inferiores às fornecidas pelo Ministério da Saúde em relação a 2008, 2009 e 2010, com 28,4%, 26,0% e 26,6% respectivamente. No entanto, as taxas de cancelamento no próprio dia são semelhantes 48,78% no estudo e, entre 44,1% e 50,5% nos dados do Ministério da Saúde. Os estudos internacionais consultados revelam taxas globais de 0,34% na China (Sung,2010) num hospitalar multidisciplinar e 30,3% (taxa de cancelamentos no dia) na Índia (Garg, 2009). CONCLUSÃO: A imputação do motivo de cancelamento é feita ao “serviço/ hospital” ou a “outros”, o utente apresenta uma taxa baixa de imputação do motivo de cancelamento. Foi encontrada uma relação de dependência entre as variáveis, com exceção da relação entre data do cancelamento e a especialidade cirúrgica. Assim, considera-se pertinente a realização de um estudo mais aprofundado e abrangente deste fenómeno nas instituições de saúde em Portugal.

Urban deforestation and urban development

This paper has developed a model of a single forest owner operating with perfect foresight in a dynamic open-city environment that allows for switching between alternative competing land uses (forest and urban use) at some point in the future. The model also incorporates external values of an even-aged standing forest in addition to the value of timber when it is harvested. Timber is exploited based on a multiple rotation model a la Faustmann with clear-cut harvesting. In contrast to previous models, our alternative land use to forest land is endogenous. Within this framework, we study the problem of the private owner as well as that of the social planner, when choosing the time to harvest, the time to convert land and the intensity of development. We also examine the extent to which the two-way linkage between urban development and forest management practices (timber production and provision of forest amenities) contributes to economic efficiency and improvements in non-market forest benefits. Finally, we consider policy options available to a regulator seeking to achieve improvements in efficiency including anti-sprawl policies (impact fees and density controls) and forest policies such a yield tax. Numerical simulations illustrate our analytical results.

The strength of the waterbed effect depends on tariff type

We show that the waterbed effect, i.e. the pass-through of a change in one price of a firm to its other prices, is much stronger if the latter include subscription rather than only usage fees. In particular, in mobile network competition with a fixed number of customers, the waterbed effect is full under two-part tariffs, while it is only partial under linear tariffs.
