Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome of this study is a composite endpoint of mortality and infectious complications related to appendectomy including intra-abdominal abscess and surigical site infection. You will find a more detailed definition of the primary endpoint in Chapter 8 (Methods) of the studyprotocol, on page 29. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secundary outcomes are amongst others: intra-abdominal abscess, superficial and/or deep surgical site infections, restart of antibiotics, hospital stay in hours, readmission rate and cost-effectiveness. Study variables are: age at time of diagnosis, location of operation, medical history (including diabetes mellitus, corticosteroid use), ASA score, gender, BMI, body temperature and laboratory results at time of presentation (CRP, WBC, eGFR), diagnostic radiological imaging, duration and severity of abdominal pain (VAS scale), antibiotic use prior to clinical diagnosis of acute appendicitis (type and dosage), prophylactic antibiotic use (type and dosage), laparoscopic or open appendectomy, duration of operation (skin-to-skin time), type of appendicitis (phlegmonous, gangrenous or perforated, with or without abscess), degree of peritonitis, level of expertise of surgeon, peritoneal irrigation and/or suction, wound management, use of (endo)loops or (endo)stapler, intraperitoneal drain placement, cultures of intra-abdominal fluid collections, histological type of appendicitis, (time to reach) discharge criteria, postoperative imaging for suspected complications, intra-abdominal abscess (IAA), deep and/or superficial surgical site infection (SSI), treatment of IAAs and SSIs, any other postoperative complication including severity, duration and doses of antibiotics received, restart of antibiotics and type, adverse events on antibiotics, type and resistance profile of cultured micro-organisms postoperatively, length of hospital stay, post-operative outpatient visit, readmission, re-interventions for complications (all within 90 days after appendectomy). | — |
