History of an abdominal operation was ascertained within the 3-year period preceding the index operation. Patients admitted to the hospital with a history of an abdominal operation (ie, bariatric, cholecystectomy, small- or large-bowel resection, prostatectomy, gynecologic) were identified using the International Classification of Diseases, Ninth Revision and Tenth Revision, Clinical Modification <\/jats:italic>procedure codes. Patients with prior IHRWM were propensity score matched (1:1) to controls both with and without a history of an abdominal surgical procedure based on clinical and operative characteristics. Data analysis was conducted from March 1 to November 27, 2021.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>The primary outcome was a composite of adverse postoperative outcomes (surgical and nonsurgical). Secondary outcomes included health care utilization determined by length of hospital stay, hospital charges, and 1-year readmissions. Logistic and Cox regression determined the association of prior IHRWM with the outcomes of interest. Additional subanalyses matched and compared patients with prior IHR without mesh (IHRWOM) to those with a history of an abdominal operation.<\/jats:p><\/jats:sec>Results<\/jats:title>Of the 914\u202f105 patients undergoing common abdominal surgical procedures (81\u202f123 bariatric [8.9%], 284\u202f450 small- or large-bowel resection [31.1%], 223\u202f768 cholecystectomy [24.5%], 33\u202f183 prostatectomy [3.6%], and 291\u202f581 gynecologic [31.9%]), all 3517 patients (age group: 46-55 years, 1547 [44.0%]; 2396 majority sex [68.1%]) with prior IHRWM were matched to patients without a history of abdominal surgical procedures. After matching, prior IHRWM was associated with increased overall complications (odds ratio [OR], 1.43; 95% CI, 1.27-1.60), surgical complications (OR, 1.51; 95% CI, 1.34-1.70), length of hospital stay (mean increase of 1.03 days; 95% CI, 0.56-1.49 days; P<\/jats:italic>\u2009&amp;lt;\u2009.001), index admission charges (predicted mean difference of $11\u202f896.10; 95% CI, $6096.80-$17\u202f695.40; P<\/jats:italic>\u2009&amp;lt;\u2009.001), and 1-year unplanned readmissions (hazard ratio, 1.14; 95% CI, 1.05-1.25; P<\/jats:italic>\u2009=\u2009.002). This trend persisted even when comparing matched patients with prior IHRWM to patients with a history of abdominal surgical procedures, and the treatment outcome disappeared when comparing patients with prior IHRWOM to those without a previous abdominal operation.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>Reoperation through a previously prosthetic-reinforced abdominal wall was associated with increased surgical complications and health care utilization. This risk appeared to be independent of a history of abdominal surgical procedures and was magnified by the presence of a prosthetic-mesh footprint in the abdominal
