Kunskaps- och Tillämpningsnivån av Standarder för Teknisk Interoperabilitet hos Leverantörer av Vårdinformationssystem (Swedish)
Abstract [en]

This thesis was one of the deliverables of StandIN. The purpose of StandIN was to propose a common framework including standards for technical interoperability. The goal of this thesis was to structure and analyze information about the knowledge- and adoption level of the standards among providers of healthcare information systems (HIS's). Moreover, it aimed to evaluate different aspect that might affect the adoption.

The target group was providers of HIS's used in Swedish county councils and regions. The information was gathered through a survey and semi-structured interviews, and stored in an Excel database. From the database, Pivot tables and charts were created in order to show the knowledge- as well as adoption level of the different standards. The results were thereafter compared to theory about interoperability and standard adoption.

It was clear that the knowledge level varied for the different standards. In addition, the adoption level was very low - except from CCOW and HL7 v2. Least adopted were domain-specific standards. The results also indicated a trend for only adopting parts of standards. Moreover, many providers stated that they performed specific integrations rather than followed common standards. This seemed to be due to the choice of standards being too wide, and the actual adoption not being consistent among the different providers. According to the providers, an introduction of a national framework based on uniform and consistent international standards was an awaited solution to the problem.

A future extension of this thesis would be to perform a similar study involving the customers. The database could also be used to do clustered analyses of the adoption state in different county councils and regions. Moreover, it could be used to analyze the development of standard adoption over time.

Abstract [sv]

Den här uppsatsen var ett utav delresultaten i StandIN, ett initiativ till att ta fram ett gemensamt ramverk med standarder för teknisk interoperabilitet. Den här uppsatsen syftade till att strukturera och analysera information om kunskaps- och tillämpningsnivån för de tilltänkta standarderna.

Målgruppen var leverantörer av vårdinformationssystem som används i Sveriges landsting och regioner. Informationen samlades in genom en enkät samt semi-strukturerade intervjuer, och lagrades sedan i en Excel-databas. Pivot-tabeller och -diagram skapades för att visualisera kunskaps- och tillämpningsnivån, och resultaten jämfördes sedan med teori om interoperabilitet och standardtillämpning.

Det var tydligt att kunskapsnivån skilde sig för de olika standarderna. Tillämpningsnivån var generellt sett väldigt låg, bortsett från CCOW och HL7 v2. Minst tillämpade var domänspecifika standarder. Det var också tydligt att centrala leverantörer inte tillämpade samma standarder, vilket troligtvis påverkar de kompletterande systemen.

Många leverantörer gjorde snarare specifika integrationer, än följde gemensamma standarder. Anledningen var att valet av standarder var för brett, och att den faktiska tillämpningen av standarder inte var konsekvent mellan olika leverantörer. Enligt leverantörerna skulle ett nationellt ramverk med enhetliga och internationella standarder vara en efterlängtad lösning på problemet.

En fortsättning på denna uppsats är att använda databasen till att göra klusteranalyser för tillämpningsnivån av standarder hos system i olika landsting och regioner. Databasen skulle också kunna användas till att analysera utvecklingen av kunskap och tillämpning över tid.
