Temporal trends in socioeconomic inequalities and risk of infection after hip fracture surgery: a nationwide cohort study, 2010–2021
Authors' conclusion
Our results indicate growing inequality in health among patients with hip fracture, whereby lower education, lack of social support, and reliance on residential care represent increasing disadvantages for infection risk.
Study context
- Population
- Patients with hip fracture undergoing surgery, Danish population-based registries, 2010–2021
- Participants
- 74,068 patients
- Exposure
- Socioeconomic position markers across four calendar periods, 2010–2021
- Outcome
- Any hospital-treated or community-treated infection after surgery; inequality measured by adjusted SII (hazard difference/100 person years) and adjusted RII (relative hazard)
- Follow-up
- 30 days after surgery
Methodological detailspopulation-based registries, additive hazard regression, Cox proportional hazard regression
- Population-based registries
- Additive hazard regression
