LinkageWiz is a Record Linkage program that makes it easy to link client records that exist in separate files or databases.
It can also be used to identify duplicate records within client databases and mailing lists. Probabilistic linkage techniques are used to join the records, utilising common identifiers such as name, date of birth, sex, Social Security Card Number, Medicare number and others. Why re-invent the wheel and write your own program when LinkageWiz is available at a reasonable cost. If you write your own program you will need to consider the following factors, as well as allowing for data quality issues and non-human data: a.. The inconsistent use of spaces and quotes in surnames; b.. Misspelt surnames and first names; c.. Use of nick names and aliases; d.. Date of birth inaccuracy/estimation; e.. Inconsistent entry of first and middle names, particularly for clients of Asian origin; f.. Registration of babies (where the given names have not yet been assigned); g.. Lack of face-to-face verification of patient details within pathology laboratories; h.. Hyphenated surnames; and i.. Surname changes, particularly for women who have changed their marital status. LinkageWiz uses a sophisticated probabilistic linkage approach to match the highest number of records possible, whilst minimising the number of false matches.
