Abstract Aim Analysis of all healthcare encounters (readmissions and emergency department visits, EDV) following both inpatient and outpatient abdominal hernia repairs (AHR), with respect to the timeline of such encounters. Material and Methods Patients undergoing AHR were identified in Maryland State Inpatient and State Ambulatory Surgery and Services Databases, 2016-2017, and all their hospital and ED encounters were assembled into a comprehensive database, covering almost 95% of all AHR performed in Maryland. Results Of the total 26,215 patients who underwent AHR (3,333 inpatient and 22,950 outpatient; 48.7% inguinal and 53.0% ventral/umbilical), 5,802 (22.1%) had at least one postoperative encounter (4,186 EDV, 1,415 readmissions, and 248 encounters for mostly outpatient another AHR). 419 (80.4%) post-operative encounters within the first 48 hours were EDV and 98 (18.8%) were readmissions. Fraction of EDV within later encounters was in 69.6–71.1% range. Most frequent reasons for EDV were urinary complaints (24.1%, 10.6% and 4.0% on POD 0–2, 3–7, and 8–30, respectively), followed by pain control issues (18.1%, 24.9%, 14.4%) and delayed return of bowel function or constipation (10.5%, 9.9%, 3.4%). Readmissions mainly occurred for aforementioned GI complaints (15.3%, 19.9%, 6.9% on POD 0–2, 3–7, and 8–30, respectively), local surgical site infections (5.1%, 15.5%, 26.8%), and respiratory complications (8.2%, 6.6%, 4.1%). Conclusions 2.3% of all patients had at least one readmission while 6.4% patients had at least one EDV within 30 days following herniorrhaphy. Early postoperative EDV were mainly caused by urinary complaints, inadequately controlled pain, or delayed bowel function. Factors associated with these largely preventable complications require dedicated analysis.
