All of this data was accessible in patients’ health records at St. Olavs University Hospital, the
health records in the municipality of Trondheim and in the accounts for both the general
hospital and the municipality for 2004 and 2005.
All information on care within the municipality was collected from the municipal electronic
health records and the municipal electronic administrative system. There was no missing data
in the patient records in the municipality.
The study was originally designed to use only paper based health records at the general
hospital. However, 15 health records (paper based) were not available at the general hospital.
As a consequence all the information that was needed, for every patient, was also collected
from the electronic health records (Doculive) used by the general hospital. There were also
some misclassifications in the patient administrative system at the general hospital. Some
general hospital readmissions were classified with the wrong diagnosis, and others were
classified as acute care readmissions when they should have been classified as elective
admissions. These misclassifications were corrected by the use of information from the
electronic health records. As a consequence, all assessments were done based on unabridged
information for all of the patients.
All data was collected by one of the authors, (HG), according to a prepared protocol from
patients’ medical records at the hospital and from primary health services. He only had access
