Essays in health economics: Volume-Outcome Effect, upcoding behaviour and the evaluation of a short-term intervention program

Evidence in the literature suggests a negative relationship between volume of medical procedures and mortality rates in the health care sector. In general, high-volume hospitals appear to achieve lower mortality rates, although considerable variation exists. However, most studies focus on US hospitals, which face different incentives than hospitals in a National Health Service (NHS). In order to add to the literature, this study aims to understand what happens in a NHS. Results reveal a statistically significant correlation between volume of procedures and better outcomes for the following medical procedures: cerebral infarction, respiratory infections, circulatory disorders with AMI, bowel procedures, cirrhosis, and hip and femur procedures. The effect is explained with the practice-makes-perfect hypothesis through static effects of scale with little evidence of learning-by-doing. The centralization of those medical procedures is recommended given that this policy would save a considerable number of lives (reduction of 12% in deaths for cerebral infarction).

Envelhecimento ativo : qualidade de vida relacionada com a saúde em idosos praticantes de atividade física : Gigong

RESUMO - Racional : A proporção da população nacional de idosos regista uma tendência crescente e as suas consequências a nível humano, social e económico são preocupantes para os gestores dos serviços de saúde. O Qigong, componente da Medicina Tradicional Chinesa, compreende a realização de movimentos suaves, controlo da respiração e meditação. Objetivos e hipóteses: No âmbito da prática de atividade física enquanto estratégia de um envelhecimento ativo, investigou-se a hipótese do Qigong contribuir para a melhoria da Qualidade de Vida Relacionada com a Saúde dos idosos participantes nesta investigação. Pretendeu-se igualmente investigar a contribuição do Qigong na redução das Frequências Respiratória e Cardíaca. Métodos: Tratou-se de um estudo quasi-experimental, antes e depois da prática de Qigong, caraterizando-se os idosos, avaliando-se a Qualidade de Vida Relacionada com a Saúde através do Questionário SF-12v2 e as Frequências Respiratória e Cardíaca, antes e depois das sessões de Qigong. Resultados: Observou-se uma adesão ao programa de 46%, constatando-se uma tendência global para a melhoria da Qualidade de Vida Relacionada com a Saúde após a prática de Qigong, com diferença estatisticamente significativa na dimensão Função Social do questionário (p = 0,046) e na redução da Frequência Respiratória (p = 0,031). Nas dimensões Desempenho Emocional e Medida Sumário Mental, observou-se um nível de tendência sugestivo de efeito (p <0,10). Foram demonstrados benefícios sentidos por parte dos idosos, decorrentes da prática de Qigong. Conclusão: O Qigong demonstrou efetividade na melhoria da qualidade de vida social e redução da Frequência Respiratória, sugerindo melhoria ao nível mental e emocional dos idosos.

Exchange rate pressure in Angola

The objective of this work is to develop an operational tool to analyze exchange rate pressure in the context of Angola. The Angolan economy exhibits a number of relevant characteristics: a closed financial account, a partially controlled current account, a highly dollarized economy and exports (oil) price determined in World markets. These features have a direct effect on the demand of foreign currency and motivate their inclusion in the specification of a model for Angola. The model provides the rational for a measure of an exchange market rate pressure (EMP) index that contains exports changes, imports changes, the foreign interest rate and inflation and the change in foreign reserves corrected for a measure dollarization. The empirical performance new measure is comparable (slightly better) to the performance of the EMP indexes obtained in Eichengreen Rose and Wyplosz (1994) and Klassen and Jager (2011).

Connect to success- consulting program of the U.S. embassy Lisbon creation of a business plan for “Quinta dos I’s”

The purpose of this project is to analyse and evaluate if the rural tourism cottage Quinta dos I’s will be profitable within the first five years of operation. It starts with a brief description of the business, followed by an industry analysis of the rural tourism market in Portugal and an intensive competitor analysis to evaluate Quinta dos I’s’ competitive advantages. The project then defines a marketing plan to generate awareness and establish the cottage in the market. Finally, a financial analysis is performed to examine the outcome of Quinta dos I’s’ recommended strategic activities. The results of this project show that the cottage is profitable after the first year of operation and expects to grow annually.
