PAsTAs - Patients Trajectories

Patient pathways have two dimensions that differ from single-service delivery: 1) Pathways consist of the ensemble of services delivered to the same patient and 2) These services are distributed over time. Some divide the patient pathway so that all events related to the same health problem form sub-pathway within a larger personal pathway.


There is little published knowledge about Patient pathways . On the other hand, there are large amounts of data about the patient in various electronic patient records (EPR). The challenge is that the EPJ data is not linked across the registriess and that it is difficult to analyze and interpret the large amounts of data in such a way that they provide meaningful information on patient pathways.

The project seeks to retrieve EPJ data from the GP, hospitals and from the care and care services and assemble them in an event stream. This registry will be the basis for our research on individual and aggregate pathways.


PAsTAs is a project that develops methods for studying and evaluating Patient pathways  in patients with long-term health service needs.

Overall goal is two-fold;

  • Develop methods for examining patient pathways in primary care based on data exported from electronic patient records
  • Investigate the effect of Patient pathways  in relation to the use of specialist health services and the patient's evaluation of the services they have received.
