The inability to invest in and develop mortality information systems has been considered the single most critical failure in health information systems. Health information systems are an integral part of health systems. This includes strengthening not only the information content but also the information systems themselves, health information platforms and infrastructure. In this article, particular focus has been placed on the regional and inter-sectoral approach to implementation adopted in Portugal. The article shows how legal and operational barriers have been overcome and focuses on the potential of the new system to improve the quality and timeliness of mortality statistics.

This qualitative study focuses on what contributes to making a music information-seeking experience satisfying in the context of everyday life. Data were collected through in-depth interviews conducted with 15 younger adults (18 to 29 years old). The analysis revealed that satisfaction could depend on both hedonic (i.e., experiencing pleasure) and utilitarian outcomes. It was found that two types of utilitarian outcomes contributed to satisfaction: (1) the acquisition of music, and (2) the acquisition of information about music. Information about music was gathered to (1) enrich the listening experience, (2) increase one's music knowledge, and/or (3) optimize future acquisition. This study contributes to a better understanding of music information-seeking behavior in recreational contexts. It also has implications for music information retrieval systems design: results suggest that these systems should be engaging, include a wealth of extra-musical information, allow users to navigate among music items, and encourage serendipitous encountering of music.
