Key result
Australian administrative databases see widespread use in perioperative outcomes research across seven methodological themes.
Why the study?
Administrative databases are increasingly used in Australian perioperative research, but their applications and associated strengths and limitations have not been comprehensively synthesised.
Systematic Review (n=167)
Australian administrative databases are widely used across surgical specialties for outcomes research, but their validity depends on coding accuracy and understanding data limitations.
Informs use of Australian administrative data for perioperative outcomes research; leaves open validation of linkage accuracy and outcome definitions.
Background Administrative databases are increasingly used in perioperative research in Australia. However, the applications of these datasets and the associated strengths and limitations have not been comprehensively synthesised. Methods A systematic review of observational studies using Australian administrative datasets to examine perioperative outcomes was conducted across MEDLINE, EMBASE, CINAHL and Web of Science on the 4 February 2026. Studies were categorised by primary methodological application. Two reviewers independently screened studies and extracted data. Risk of bias was assessed using ROBINS‐I. Results Of 3485 records identified, 167 publications met inclusion criteria. Studies spanned multiple surgical specialties and jurisdictions and clustered into seven themes: (1) outcome risk modelling ( n = 50), identifying and stratifying factors associated with postoperative outcomes; (2) temporal epidemiology ( n = 24), examining changes in surgical activity and outcomes over time; 14 studies spanned both outcome risk modelling and temporal epidemiology themes; (3) surgical comparison ( n = 23), evaluating outcome differences between operative approaches or treatment strategies; (4) hospital benchmarking ( n = 21), assessing variation across institutions, sectors and regions; (5) health economics ( n = 20), analysing costs and resource utilisation; (6) policy evaluation ( n = 8), investigating effects of guideline implementation or system‐level reforms and (7) health equity assessment ( n = 7), exploring disparities in perioperative outcomes across demographics and socioeconomic groups. Conclusion Australian administrative databases are widely used across broad surgical specialties for outcomes research. The validity of these studies remains contingent on coding accuracy and an understanding of the inherent data limitations. The current literature is state‐focused, limiting broader generalisability of findings.

Chen et al. (2026) conducted a systematic review in Perioperative outcomes (n=167). Australian administrative databases was evaluated on Primary methodological application. A systematic review of 167 studies found that Australian administrative databases are widely used in perioperative outcomes research across seven methodological themes.
