Introduction: Access to surgical care is an essential element of health-systems strengthening. This study aims to compare two diverse healthcare settings in South Asia and the United States (US).
Methods: Patients at the Aga Khan University Hospital (AKUH), Pakistan were matched to patients captured in the US Nationwide Inpatient Sample (US-NIS) from 2009 to 2011. Risk-adjusted differences in mortality, major morbidity, and LOS were compared using logistic and generalized-linear (family gamma, link log) models after coarsened-exact matching.
Results: A total of 2,244,486 patients (n = 4867 AKUH; n = 2,239,619 US-NIS) were included. Of those in the US-NIS, 990,963 (42.5%) were treated at urban-teaching hospitals, 332,568 (14.3%) in rural locations. Risk-adjusted odds of reported mortality were higher for Pakistani patients (OR[95%CI]: 3.80[2.68 -5.37]), while odds of reported complications were lower (OR[95%CI]: 0.56[0.48-0.65]). No differences were observed in LOS. The difference in outcomes was less pronounced when comparing Pakistani patients to American rural patients.
Conclusion: These results demonstrate significant reported morbidity, mortality differences between healthcare systems. Comparative assessments such as this will inform global health policy development and support.
