It outlines how vitagroup\u2019s Health Intelligence Platform (HIP) underpins the region\u2019s open data foundation and details the technical challenges encountered when moving from fragmented systems to a longitudinal, patient-centred model.<\/p>\n<p>Drawing on extensive optimisation work, the paper demonstrates how performance barriers in large-scale openEHR deployments can be overcome through a combination of in-memory query processing, targeted indexing, and query design strategies. The results show substantial improvements in query response times and scalability, while highlighting the need for a hybrid architectural approach to support both transactional and analytical workloads.<\/p>\n<p>The findings provide a practical blueprint for healthcare systems looking to implement open, vendor-neutral data platforms at regional or national scale.[\/vc_column_text]<div class=\"ult-spacer spacer-69d0e53231b7c\" data-id=\"69d0e53231b7c\" data-height=\"30\" data-height-mobile=\"30\" data-height-tab=\"30\" data-height-tab-portrait=\"\" data-height-mobile-landscape=\"\" style=\"clear:both;display:block;\"><\/div>[vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>Get the whitepaper \u2013 available in English and Spanish<\/h2>\n<p>[\/vc_column_text]<div class=\"ult-spacer spacer-69d0e53231b97\" data-id=\"69d0e53231b97\" data-height=\"30\" data-height-mobile=\"30\" data-height-tab=\"30\" data-height-tab-portrait=\"\" data-height-mobile-landscape=\"\" style=\"clear:both;display:block;\"><\/div><style type=\"text\/css\" data-type=\"the7_shortcodes-inline-css\">#default-btn-3ae53ab5cec6e11a915cba6f0cfabb08.ico-right-side > i {\n  margin-right: 0px;\n  margin-left: 8px;\n}\n#default-btn-3ae53ab5cec6e11a915cba6f0cfabb08 > i {\n  margin-right: 8px;\n}<\/style><a href=\"https:\/\/hip.vitagroup.ag\/en\/download-whitepaper-building-a-regional-health-data-backbone\/\" class=\"default-btn-shortcode dt-btn dt-btn-m link-hover-off secondary btn-inline-left \" id=\"default-btn-3ae53ab5cec6e11a915cba6f0cfabb08\" title=\"Whitepaper\"><span>Download now<\/span><\/a>[\/vc_column][\/vc_row][\/vc_section][vc_section full_width=&#8221;stretch_row&#8221; disable_element=&#8221;yes&#8221; el_class=&#8221;lichtgrau no-padding-top&#8221;][vc_row el_class=&#8221;cta-card akzent&#8221;][vc_column el_class=&#8221;lichtgrau no-padding-top&#8221;][vc_column_text css=&#8221;&#8221; el_class=&#8221;top-title&#8221;]Pressemitteilung zum Download[\/vc_column_text][vc_column_text css=&#8221;&#8221;]\u201eKatalonien verl\u00e4ngert Vertrag mit der vitagroup f\u00fcr die Infrastruktur der einheitlichen Patientenakte&#8221;[\/vc_column_text]<div class=\"ult-spacer spacer-69d0e53231c29\" data-id=\"69d0e53231c29\" data-height=\"30\" data-height-mobile=\"30\" data-height-tab=\"30\" data-height-tab-portrait=\"\" data-height-mobile-landscape=\"\" style=\"clear:both;display:block;\"><\/div><style type=\"text\/css\" data-type=\"the7_shortcodes-inline-css\">#default-btn-9f80395ad80feefe58b6696b533d4c99.ico-right-side > i {\n  margin-right: 0px;\n  margin-left: 17px;\n}\n#default-btn-9f80395ad80feefe58b6696b533d4c99 > i {\n  margin-right: 17px;\n}<\/style><a href=\"title:Pressemitteilung|target:_blank\" class=\"default-btn-shortcode dt-btn dt-btn-m link-hover-off ico-right-side secondary invers btn-inline-left \" id=\"default-btn-9f80395ad80feefe58b6696b533d4c99\"><span>PDF downloaden<\/span><i class=\"icomoon-the7-font-the7-arrow-13\"><\/i><\/a>[\/vc_column][\/vc_row][\/vc_section]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>This whitepaper presents one of the largets implementations of an openEHR-based Clinical Data Repository at population scale, supporting over 13 million patients in Catalonia.<\/p>\n","protected":false},"author":11,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[181],"tags":[],"class_list":["post-12019","post","type-post","status-publish","format-standard","hentry","category-no-teaser","category-181","description-off"],"acf":[],"_links":{"self":[{"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/posts\/12019","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/users\/11"}],"replies":[{"embeddable":true,"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/comments?post=12019"}],"version-history":[{"count":4,"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/posts\/12019\/revisions"}],"predecessor-version":[{"id":12026,"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/posts\/12019\/revisions\/12026"}],"wp:attachment":[{"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/media?parent=12019"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/categories?post=12019"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hip.vitagroup.ag\/en\/wp-json\/wp\/v2\/tags?post=12019"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
