Análise de custo-efectividade da terapêutica de ressincronização cardíaca : avaliação da selecção baseada na dessincronia mecânica

RESUMO - A Terapêutica de Ressincronização Cardíaca (TRC) apresenta benefícios significativos na classe funcional, função ventricular, hospitalização e mortalidade. É uma técnica com custos elevados e, com os actuais métodos de selecção de doentes, a taxa de não-respondedores ronda os 30%. Objectivo: Compreender se a inclusão da dessincronia mecânica (DM) na selecção de doentes para TRC contribui para a sua relação custo-efectividade, na perspectiva do Serviço Nacional de Saúde português. Metodologia: Estudo prospectivo baseado em coortes histórias de 12 meses de dois grupos submetidos a TRC com desfibrilhador, o grupo de intervenção com doentes seleccionados com inclusão da DM (n=133) e o de controlo com selecção baseada exclusivamente nas recomendações internacionais (n=71). Reuniram-se dados clínicos e de custos nos 12 meses subsequentes à implantação, para cálculo do rácio custo-efectividade incremental (RCEI). Resultados: O grupo de intervenção apresentou uma sobrevivência de 91% e o de controlo de 93%, aos 12 meses (p=0,335). O grupo de intervenção apresentou 60 re-internamentos e o de controlo 46 re-internamentos por qualquer causa aos 12 meses (p=0,032), com RCEI=6.886,09€/re-internamento evitado. O grupo de intervenção apresentou 19 re-internamentos e o de controlo apresentou 31 re-internamentos por Insuficiência Cardíaca (IC) descompensada aos 12 meses (p<0,001), com RCEI=2.686,26€/re-internamento por IC descompensada evitado. Relativamente à melhoria da classe funcional e da fracção de ejecção não foi possível estabelecer associações com custos (p>0,05). Conclusão: É seguro afirmar que recomendar a selecção com inclusão da DM, nos hospitais com capacidade instalada, é um passo positivo na redução de custos com re-internamentos de doentes com TRC.

Managing innovation complexity: About the co-existence of innovation types

The purpose of this study is to contribute to the changing innovation management literature by providing an overview of different innovation types and organizational complexity factors. Aiming at a better understanding of effective innovation management, innovation and complexity are related to the formulation of an innovation strategy and interaction between different innovation types is further explored. The chosen approach in this study is to review the existing literature on different innovation types and organizational complexity factors in order to design a survey which allows for statistical measurement of their interactions and relationships to innovation strategy formulation. The findings demonstrate interaction between individual innovation types. Additionally, organizational complexity factors and different innovation types are significantly related to innovation strategy formulation. In particular, more closed innovation and incremental innovation positively influence the likelihood of innovation strategy formulation. Organizational complexity factors have an overall negative influence on innovation strategy formulation. In order to define best practices for innovation management and to guide managerial decision making, organizations need to be aware of the co-existence of different innovation types and formulate an innovation strategy to more closely align their innovation objectives.

Evaluation of the welfare impact of regulating mobile termination rates in Portugal

Following the European Commission’s 2009 Recommendation on the Regulatory Treatment of Fixed and Mobile Termination Rates in the EU, the Portuguese regulatory authority (ANACOM) decided to reduce termination prices in mobile networks to their long-run incremental cost (LRIC). Nevertheless, no serious quantitative assessment of the potential effects of this decision was carried out. In this paper, we adapt and calibrate the Harbord and Hoernig (2014) model of the UK mobile telephony market to the Portuguese reality, and simulate the likely impact on consumer surplus, profits and welfare of four different regulatory approaches: pure LRIC, reciprocal termination charges with fixed networks, “bill & keep”, and asymmetric termination rates. Our results show that reducing MTRs does increase social welfare, profits and consumer surplus in the fixed market, but mobile subscribers are seriously harmed by this decision.

Market risk charge of the trading book: a comparison of the Basel II and Basel III

This paper aims to investigate if the market capital charge of the trading book increased in Basel III compared to Basel II. I showed that the capital charge rises by 232% and 182% under the standardized and internal model, respectively. The varying liquidity horizons, the calibration to a stress period, the introduction of credit spread risk, the restrictions on correlations across risk categories and the incremental default charge boost Basel III requirements. Nevertheless, the impact of Expected shortfall at 97.5% is low and long term shocks decrease the charge. The standardized approach presents advantages and disadvantages relative to internal models.

Comprehensive income: evidence from Portuguese listed companies on reporting choices and value relevance

This work project aims at analysing choices related to Comprehensive income (CI) of Portuguese listed firms and understanding the reasons behind them. Additionally, it studies the relevance of CI versus Net Income (NI). It was found that firm’s size and volume of Other comprehensive income (OCI) are positively related with the choice for separate statements while smaller firms with positive NI and negative OCI tend to disclose less information about taxes. The value relevance of CI proved to be superior to that of NI but OCI seems to have no incremental value relevance.

Management consulting labs Galp loyalty

The main objective of this project was to investigate methods to create a new loyalty approach for Galp Energia in order to improve customer retention and reduce churn, related with the expansion of hypermarket chains’ in the Fuel Retail Market and the country’s economical situation. The team carried out on-spot surveys and focus groups, researched loyalty programs’ best practices, analyzed peers practices and the company’s past performance in order to find important customer insights. These were used to develop the final recommendations resulting in a new paradigm to the group’s loyalty approach alongside incremental improvements to the current loyalty solutions.

Management consulting labs-Galp loyalty learning experience

The purpose of this project was to analyze Galp’s loyalty approach in the Portuguese fuel market given the industry context, namely the entry of hypermarket and the resulting increase in competitiveness. The team performed analyses based on analytical models, qualitative research and internal interviews in order to assess Galp’s potential in the field of loyalty and consumers’ behavior. The final recommendations were based on incremental improvements to the Galp’s existing loyalty tool and an innovative paradigm change of the approach to loyalty.
