Data quality is defined by Health Information and Quality Authority HIQA in Ireland as “Data that are complete, valid, accurate, reliable, relevant, legible and available in a timely manner.” (HIQA, 2021) We need quality data for better decision-making, healthcare management, policy development, public health campaigns, and population health evaluation. At the NPEC we use a variety of methodologies to achieve this: the implementation of the HIQA data quality framework, development of online data collection tools, visual aids for the dissemination of information.
