Probabilistic linkage to enhance deterministic algorithms and reduce data linkage errors in hospital administrative data

Probabilistic linking to enhance deterministic algorithms and reduce linkage errors in hospital administrative data

background The pseudonymisation algorithm used to link together episodes of care belonging to the same patient in England [Hospital Episode Statistics ID (HESID)] has never undergone any formal evaluation to determine the extent of data linkage error. Objective To quantify improvements in linkage accuracy from adding probabilistic linkage to existing deterministic HESID algorithms. Methods Inpa...

Probabilistic Linkage of Persian Record with Missing Data

Extended Abstract. When the comprehensive information about a topic is scattered among two or more data sets, using only one of those data sets would lead to information loss available in other data sets. Hence, it is necessary to integrate scattered information to a comprehensive unique data set. On the other hand, sometimes we are interested in recognition of duplications in a data set. The i...

Data linkage errors in hospital administrative data when applying a pseudonymisation algorithm to paediatric intensive care records

OBJECTIVES Our aim was to estimate the rate of data linkage error in Hospital Episode Statistics (HES) by testing the HESID pseudoanonymisation algorithm against a reference standard, in a national registry of paediatric intensive care records. SETTING The Paediatric Intensive Care Audit Network (PICANet) database, covering 33 paediatric intensive care units in England, Scotland and Wales. ...

Linkage between neurological registry data and administrative data.

This section of the guideline discusses considerations when planning and designing a registry that will require linkage to administrative data. Administrative data may include hospitalization and surgical or other procedure data; physician billing data; vital statistics data (e.g. births, deaths); prescription and other pharmacy data; long-term care services and admissions; and other data colle...
