The growing use of information systems in the healthcare sector, on top of increasing patient populations, diseases and complicated medication regimens, is generating enormous amounts of complex data that are known by the term ‘big data’. Healthcare sectors are showing a growing interest in making use of sophisticated technologies to utilise big data to improve healthcare delivery and service management. Ms Weerasinghe studied policy makers, planners, funders, implementers and clinicians across the New Zealand healthcare sector to understand their views on the use of big data and related technologies in health. She found there was a shared understanding of the importance of data quality, the increasing challenges of privacy and security, and the importance of new types of data in measuring health outcomes. However, misalignment was observed in differing definitions of big data, as well as perceptions around data ownership, data sharing, use of patient-generated data and interoperability.
