We constructed a network by equating access and updates of a patient\u2019s EHR to a provider-patient interaction. We then considered shared patient record access as the basis for a second network that we termed the provider collaboration network. We calculated network statistics, the modularity of provider interactions, and provider cliques.<\/jats:p><jats:p>Results We identified 548 patient records accessed by 5113 healthcare providers in 2012. The provider collaboration network had 1504 nodes and 83\u2009998 edges. We identified 7 major provider collaboration modules. Average clique size was 87.9 providers. We used a graph database to demonstrate an ad hoc query of our provider-patient network.<\/jats:p><jats:p>Discussion Our analysis suggests a large number of healthcare providers across a wide variety of professions access records of patients with heart failure during their hospital stay. This shared record access tends to take place not only in a pairwise manner but also among large groups of providers.<\/jats:p><jats:p>Conclusion EHRs encode valuable interactions, implicitly or explicitly, between patients and providers. Network analysis provided strong evidence of multidisciplinary record access of patients with heart failure across teams of 100+ providers. Further investigation may lead to clearer understanding of how record access information can be used to strategically guide care coordination for patients hospitalized for heart failure.<\/jats:p>","DOI":"10.1093\/jamia\/ocu017","type":"journal-article","created":{"date-parts":[[2015,2,26]],"date-time":"2015-02-26T07:48:08Z","timestamp":1424936888000},"page":"299-311","source":"Crossref","is-referenced-by-count":47,"title":["Visualizing
