Auckland GP cooperative and primary health organisation ProCare has partnered with the University of Auckland and the University of Otago to run a large-scale population health study on the effects of multi-morbidity on the risk of hospitalisation or death from heart disease or stroke.

ProCare-collected data on more than 550,000 Aucklanders will be anonymised and linked with regional blood test results from the TestSafe clinical data repository as well as national health databases reporting hospitalisations, deaths and community pharmacy dispensing to track patients over time and determine the effects of having two or more long-term conditions on the risk of hospitalisation or death from heart disease or stroke.
