US veterans are a unique group that is predominantly male and tends to have higher rates of medical comorbidities and tobacco use, common risk factors for hernia development.

Patients were predominantly male (306\u202f905 [99.4%]; 1971 female patients [0.6%]), with a median (IQR) age of 65 (57-73) years. They had high rates of hypertension (198\u202f792 [64.4%]), depression (102\u202f880 [33.3%]), chronic obstructive pulmonary disease (82\u202f608 [26.7%]) and alcohol use disorder (68\u202f427 [22.2%]). A total of 60\u202f088 patients (19.5%) underwent minimally invasive (MIS) IHR while 246\u202f403 procedures (79.8%) were open. Most were outpatient (300\u202f400 [97.3%]); only 17\u202f352 (5.6%) were urgent or emergent. Compared with men, women were more likely to undergo MIS-IHR (452 women [22.9%] vs 59\u202f636 men [19.4%]) and urgent\/emergent procedures (218 women [11.1%] vs 17\u202f134 men [5.6%]). Annual IHR volume increased from 12\u202f086 in 2002 to 17\u202f897 in 2022, with an increase in MIS-IHR from 1102 (9.2%) to 7286 (41.0%). After a decline during COVID-19, IHR numbers have since recovered and surpassed pre-2020 volume. Throughout the study period, IHRs performed in the community were less likely to be urgent or emergent cases (1006 [3.0%] vs 16\u202f346 [5.9%] in Veterans Affairs [VA] facilities).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-soi260010-10\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>This study found that over the past 20 years, the volume of IHRs performed in the VHA system has increased, along with MIS approaches.
