slide1. Assessing the Impact of Individual Risk Factors in Predicting Adverse Outcomes of Ventral Hernia Repair: An ACHQC Analysis Delaney D. Ding

slide2. Disclosures This work was supported by the 2022 Resident and Fellow Research Grant from the Abdominal Core Health Quality Collaborative (ACHQC)<br>
slide3. Background Ventral hernia repair (VHR) complication risk factors<br>
slide4. Aim and Hypothesis Quantify and compare the influence of numerous risk factors on VHR complications for ACHQC patients AIM Hypothesis We hypothesize that hernia- and procedure-specific factors are more predictive of surgical outcomes compared to patient-specific risk factors.<br>
slide5. Methods Ret Adults, Elective VHR, 30-day follow-up completed
Primary outcome: overall 30-day postoperative complications
Area under the curve (AUC) of the receiver operator curve Area Under Curve (AUC)<br>
slide6. Patient characteristics Elective VHR (n=35,108)<br>
slide7. Hernia characteristics Elective VHR (n=35,108)<br>
slide8. Operative Details Elective VHR (n=35,108)<br>
slide9. Results Elective VHR (n=35,108)<br>
slide10. Results AUC ≥ 0.60:
Defect width
Defect length
Drain use
Myofascial Release
ASA class
Mesh position
Incisional hernia<br>
slide11. Conclusions ><br>
slide12. Conclusions Most individual risk factors were poorly associated with VHR complications Assessment of VHR complication risk should not rely on a single risk factor<br>
slide13. Limitations Sampling bias
ACHQC is designed to measure outcomes of VHR, but not watchful waiting
Long-term outcomes (e.g. recurrence) were not evaluated<br>
