New publication in the Journal of the American Heart Association

Red Door Analytics published research examining the relationship between neighbourhood deprivation and survival outcomes following coronary artery bypass grafting using Medicare administrative data. The study found that patients from less deprived neighbourhoods had better survival rates than those from highly deprived areas, with this advantage varying significantly across racial and ethnic groups.

In an interview, Alessandro discussed why the research focused on standardised survival probabilities rather than hazard ratios. He explained that survival probabilities offer more intuitive real-world interpretation, and that regression standardisation allowed the team to estimate the average survival probability among exposed and unexposed while adjusting for the covariates. The key takeaway emphasised that the interaction between socio-economic status, race/ethnicity, and survival after CABG is complex, suggesting policies addressing deprivation alone may not produce equitable benefits.
