Introduction: In adults, readmission within 30 days of heart surgery is a major factor in hospital costs for heart surgery, but current data on risk factors for readmission are scarce. Therefore, we sought to identify performance-adjusted risk factors for coronary artery bypass graft (CABG) re-admissions.

Material and Methods: The records of patients who underwent CABG at our institution between 2012-14 were analyzed for contrast with prospectively recorded case studies, including New York Cardiac Surgery Reporting System (CSRS) events, prescriptions, and testing costs.

Results: Read rate 13% ; The CSRS estimated value is 8.7% (observed/predicted ratio = 1.5). The median time from CABG discharge to readmission was 6 days (interquartile range [IQ] 3 to 13 days). The median length of hospital stay was 4 days (IQ 2 to 7 days). The most common causes of readmission were heart disease (n = 40 [25% of readmissions]) and pneumonia (n = 36 [23%]), including pleural effusions. In addition to CSRS status, serum creatinine excretion alone was not associated with increased readings (p=0.5) OR] 5.7, %95 GA 1.7 ila 18.7).

Conclusion: Readmission for coronary artery bypass surgery remains an ongoing medical challenge. Given that readmissions usually occur within the first week after discharge and are usually short-term, attention is paid to follow-up care and risk of readmission (compare, for example, abnormal serum creatinine or abnormal reactivity) and/or multiple causes of readmission. may reduce readmission after CABG (eg, pleural effusion).
