Summary of Work The overall objective of this proposal is to identify factors associated with cardiovascular complications ≤90 days of cancer surgery among older adults with solid tumors and elicit the perspectives of PCPs on the quality of communication with surgical providers following patients’ surgery. Our central hypothesis is that older adults with solid tumors who are at increased risk of cardiovascular complications are identifiable early in the perioperative period and that potentially modifiable factors in care coordination (such as having a PCP, early post-discharge follow-up with PCP, direct communication with PCP) are associated with lower rates of cardiovascular complications 90-days post-surgery.
