The modified Activities Assessment Scale (AAS) is a 13-question abdominal wall quality of life (AW-QOL) survey validated in patients undergoing ventral hernia repair (VHR). No studies have assessed AW-QOL among individuals without abdominal wall pathology. The minimal clinically important difference (MCID) of the modified AAS and its implications for the threshold at which VHR should be offered also remain unknown. Our objectives were to (1) establish the AW-QOL of patients with a clinical abdominal wall hernia versus those with no hernia, (2) determine the MCID of the modified AAS, and (3) identify the baseline quality of life (QOL) score at which patients derive little clinical benefit from VHR. Patient-centered outcomes data for all patients presenting to General Surgery and Hernia Clinics October-December 2016 at a single safety-net institution were collected via a prospective, cross-sectional observational study design. Primary outcome was QOL measured using the modified AAS. Secondary outcome was the MCID. Patients with no hernia had modified AAS scores of 81.6 (50.4-94.4), while patients with a clinically apparent hernia had lower modified AAS scores of 31.4 (12.6-58.7) (p < 0.001). The MCID threshold was 7.6 for a slight change and 14.9 for definite change. Above a modified AAS score of 81, the risk of worsening a patient's QOL by surgery is higher than the chances of improvement. VHR can improve 1-year postsurgical AW-QOL to levels similar to that of the general population. The MCID of the modified AAS is 7.6 points. Patients with high baseline scores should be counseled about the lack of potential benefit in QOL from elective VHR.
