Validation of Aboriginal identification algorithms in the APDC and ABS Mortality Data using the 45 and Up Study.

Louisa Jorm (PI), Emily Banks, Alastair Leyland, Sandra Eades, Tim Churches, Mary Haines, Sanja Lujic and Deborah Randall

Project aim(s):

• To investigate the factors (hospital, person or admission) that predict ‘correct’ Aboriginal identification in hospital inpatient and mortality data, with self-identified Aboriginal status in the 45 and Up Study serving as a ‘gold standard’;
• To develop a set of candidate algorithms for improving Aboriginal identification for use with linked hospital inpatient and mortality data, informed by (1);
• To investigate the comparative validity (sensitivity, specificity, positive and negative predictive values) of these algorithms; and
• To investigate how estimated Aboriginal rates and rate ratios for hospital separations, hospital outcomes and mortality vary according to the algorithm used.
