Key result
Inclusion of cross-jurisdictional hospital and Medicare Benefits Schedule data increased the enumeration of STEMI hospitalisations for NSW residents by 8% and procedure rates from 85.6% to 88.2%.
Why the study?
NSW STEMI patients often undergo transfers including stays in other jurisdictions, requiring cross-jurisdictional data linkage to accurately enumerate hospitalisations and assess cardiac procedure timing.
Does the inclusion of cross-jurisdictional and MBS data improve the ascertainment of STEMI hospitalisations and cardiac procedure rates in NSW residents?
Observational (n=16,659)
Yes
Does the inclusion of cross-jurisdictional and MBS data improve the ascertainment of STEMI hospitalisations and cardiac procedure rates in NSW residents?
Cross-jurisdictional data linkage is essential for accurately estimating STEMI hospitalizations and revascularization rates, particularly for patients living near jurisdictional borders.
Jurisdiction-specific data may underestimate STEMI events and procedures; supports cross-jurisdictional linkage for accurate population estimates.
Introduction: The patient journey for residents of New South Wales (NSW) Australia with ST-elevation myocardial infarction (STEMI) often involves transfer between hospitals and these can include stays in hospitals in other jurisdictions. Objective: To estimate the change in enumeration of STEMI hospitalisations and time to subsequent cardiac procedures for NSW residents using cross-jurisdictional linkage of administrative health data. Methods: Records for NSW residents aged 20 years and over admitted to hospitals in NSW and four adjacent jurisdictions (Australian Capital Territory, Queensland, South Australia, and Victoria) between 1 July 2013 and 30 June 2018 with a principal diagnosis of STEMI were linked with records of the Australian Government Medicare Benefits Schedule (MBS). The number of STEMI hospitalisations, and rates of angiography, percutaneous coronary intervention and coronary artery bypass graft were compared for residents of different local health districts within NSW with and without inclusion of cross-jurisdictional data. Results: Inclusion of cross-jurisdictional hospital and MBS data increased the enumeration of STEMI hospitalisations for NSW residents by 8% (from 15,420 to 16,659) and procedure rates from 85.6% to 88.2%. For NSW residents who lived adjacent to a jurisdictional border, hospitalisation counts increased by up to 210% and procedure rates by up to 70 percentage points. Conclusions: Cross-jurisdictional linked hospital data is essential to understand patient journeys of NSW residents who live in border areas and to evaluate adherence to treatment guidelines for STEMI. MBS data are useful where hospital data are not available and for procedures that may be conducted in out-patient settings.

Igic et al. (2023) conducted an observational in ST-segment-elevation myocardial infarction (STEMI) (n=16,659). Inclusion of cross-jurisdictional hospital and Medicare Benefits Schedule (MBS) data vs. NSW hospital data alone was evaluated on Enumeration of STEMI hospitalisations and procedure rates (2.6 percentage point increase). Inclusion of cross-jurisdictional hospital and Medicare Benefits Schedule data increased the enumeration of STEMI hospitalisations for NSW residents by 8% and procedure rates from 85.6% to 88.2%.
