One third of hospital costs for atherothrombotic disease are attributable to readmissions: a linked data analysis.

Factors associated with time to ATD readmission Having ATD in more than one vascular territory at the index admission was highly significant, with the risk of ATD readmission approximately 1.5 times higher in those with polyvascular disease compared to those with only one vascular territory affected controlling for age, sex, comorbidity, admission type, procedures, and episode length of stay (HR 1.45; 95% CI 1.27, 1.66).

Readmission costs at each follow-up point were also slightly higher for rural residents, but the difference did not reach statistical significance.
