Can Researchers Assess the Suitability of Datasets to Answer Their Research Questions, with Access to Metadata Only?

Health research increasingly requires effective ways to identify existing datasets and assess their suitability for research. We sought to test whether researchers could use an existing metadata catalogue to assess the suitability of datasets for addressing specified research questions. Five datasets were described in the National Institute for Health Research Health Informatics Collaborative metadata catalogue, and for each dataset five associated research questions were formulated, some of which were answerable with the dataset while others were not.

Health Economic Analysis of Access Site Practice in England During Changes in Practice: Insights From the British Cardiovascular Interventional Society.

Background: Transradial access (TRA) for percutaneous coronary intervention (PCI) is associated with a reduced risk of mortality compared with transfemoral access, access site-related bleeding complications, and shorter length of stay. The budget impact from a healthcare system that has largely transitioned to TRA for PCI has not been previously published.

Methods And Results: Data from 323 656 patients undergoing PCI between 2010 and 2014 were obtained from the British Cardiovascular Intervention Society database.
