Lower social capital correlates with higher rates of unplanned surgery.

Medicare beneficiaries from low social capital areas underwent unplanned surgery for access-sensitive conditions at higher rates (40.67%) than those from high social capital areas (35.28%). Additionally, they experienced more postoperative complications (24.99% vs. 22.90%). However, no significant differences were noted in readmission or mortality rates. When analyzing elective procedures, disparities in complications diminished, with readmission rates remaining insignificant and mortality rates equalized. Enhancing social capital may help reduce unplanned surgeries in these communities.
