A database consisting of all hip fractures treated in Norwegian hospitals
from 1994 through 2008 has been established by the Norwegian
Epidemiologic Osteoporosis Studies (NOREPOS) research collaboration
(www.norepos.no). This database, “NORHip”, includes almost 140,000
incident hip fractures. The validity of the database has been assessed
by comparisons to local hip fracture registries (verified by hospital records
and radiographic archives) in the cities of Oslo and Tromsø.More information on the data quality assurance is found in Omsland
et al.
