de Bruin, A., Kardaun, J., Gast, F., et al. "Record linkage of hospital discharge register with population register: Experiences at Statistics Netherlands". Statistical Journal of the United Nations ECE 21 (2004): 23-32.


Linkage


Linkage is possible, but linkage to key LMR is limited, therefore not all discharges can be linked. Data can be longitudinally linked with auxiliary file of uniquely linkable persons based on population register.


Data quality


Missing registrations of hospitalizations, unknown diagnosis (from 2006 onwards; 18% in 2011). Missing registrations are imputed to make a complete file, but the imputed records cannot be linked.


Change in ICD-version from 2012 onwards (ICD10). Linkable data from 1995 onwards.


Yes, except for ICD9-ICD10 change from 2012 onwards


Applicability


Strengths: The data source provides long time series and high coverage (up to 2005). Weaknesses: The registry is missing registrations from 2006 onwards.
