Given the high frequency of cardiovascular disease, vascular surgery may be frequent among individuals with serious mental illness (SMI). Unfortunately, there hasn't been much research done on the postoperative results of vascular surgery, especially in a subgroup of SMI. We used data from the South London and Maudsley NHS Foundation Trust (SLaM) using its Clinical Record Interactive Search (CRIS) platform and linkage with Hospital Episode Statistic to conduct a retrospective observational analysis (HES). OPCS version codes were used to identify patients who had undergone vascular surgery. For patients with SMI compared to the general population, the length of stay (LOS) was simulated using incidence rate ratios (IRRs) and a month's worth of emergency hospital readmissions (ORs).
