Abstract

Background Acute myocardial infarction (AMI) has poorer outcomes in disadvantaged populations such as those in regional and remote locations. We compared long-term outcomes associated with presentation to regional or remote hospitals among AMI patients.Methods and results Administrative claims data from New South Wales (27% regional and remote residents) was used to identify patients >18 years admitted to any NSW hospital with a principal diagnosis of AMI (ICD10 codes: I21·0-I21·4) between 01/07/2004 and 30/06/2008. Hospital of presentation location with a population of <250,000 was defined as regional and remote while hospitals with a population >250,000 were deemed urban. Receipt of revascularisation and mortality were analysed and adjusted for age, comorbidities and previous revascularisation. Patients were censored at death or end of the follow-up period (31 December 2009). 39,798 patients were identified with 9,393 (23.6%) regional and remote presenters. In multivariable models, regional and remote presentation was associated with reduced rates of revascularisation (OR 0.30 95%CI 0.28-0.32; p<0.001), no impact on overall mortality (HR 1.04 95%CI 0.99-1.02; p=0.11), but with increased mortality for patients presenting with STEMI (HR 1.14; 95% CI 1.06-1.23; p<0.001). The propensity analysis was consistent with these findings.Conclusions Presentation to a regional and remote hospital was associated with lower revascularisation rates following AMI, but with a higher long-term mortality if presenting with ST segment elevation.

  • Rural and remote Australians and New Zealanders experience a higher rate of adverse outcomes from acute myocardial infarction.

    “Rural and remote Australians and New Zealanders have a higher rate of adverse outcomes due to acute myocardial infarction, driven by many factors [3,4].”

    From Rural and Remote Cardiology During the COVID-19 Pandemic: Cardiac Society of Australia and New Zealand (CSANZ) Consensus Statement (2020) · cites this paper as [3]

    The Mortality and Sensitivity Analyses sections (pages unavailable) report higher crude mortality for regional and remote NSW patients and higher adjusted mortality for those presenting with STEMI. They found no significant adjusted mortality difference for AMI patients overall, and the study did not examine New Zealanders. (LLM, conf=0.90)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
