Teacher: Now, understand the problem? Solve this instance: Question: Is care of patients undergoing vascular surgery at safety net public hospitals associated with higher cost but similar mortality to nonsafety net hospitals?
Answer: Patients undergoing vascular surgery at SNPHs, despite being younger, had higher comorbidities, presented more urgently with more advanced disease, and incurred higher costs than the SNPH cohort despite similar adjusted odds of in-hospital mortality. Delayed presentation and higher comorbidities are most likely related to poor access to routine and preventive health care for the SNPH patients.
