Purpose
This is an observational study to evaluate the relative importance of the known risk factors for severe surgical site infections (SSIs) on the development of the more severe SSI cases, and to describe the demographic, clinical features, etiology and the management and outcome of patients suffering from severe SSIs in Spain.

Primary Outcome Measures:
- Percentage of Participants With Pre-surgical Morbidities [ Time Frame: Baseline (Pre-surgical) ] [ Designated as safety issue: No ]Morbidities (risk factors) included: neoplasm, tobacco use, body mass index (weight in kilograms divided by height in meters squared [BMI kg/m2]) greater than (>) 30, diabetes mellitus (DM), immunosuppression/ corticosteroids, anemia (hemoglobin [Hb] less than (>) 9 grams per deciliter [gr/dL]) or malnutrition (hypoalbuminemia).
- Percentage of Participants Who Received Pre-surgical Antibiotic Prophylaxis [ Time Frame: Baseline (Pre-surgical) ] [ Designated as safety issue: No ]
- Percentage of Participants Who Underwent Emergency Surgery or Scheduled Surgery [ Time Frame: Day 0 (day of surgery) ] [ Designated as safety issue: No ]
- Percentage of Participants With Classification of Risk of Surgical Infection of Clean-contaminated, Contaminated or Dirty [ Time Frame: Day 0 (day of surgery) ] [ Designated as safety issue: No ]Surgical infection risk class: Clean-contaminated: controlled entry in normally colonized body cavities/no unusual contamination/minimum fluid discharge/minimal sterile technique violation/re-surgery on clean surgical incision within 7 days/negative surgical exploration through intact skin. Contaminated: no acute inflammation/purulent discharge/significant fluid/material violation of sterile technique/penetrating trauma less than 4 hours old/graft in chronic skin wounds. Dirty: pus-abscess drainage/ preoperatively colonized body cavity perforated/penetrating trauma more than 4 hours old.
- Type of Surgeon [ Time Frame: Day 0 (day of surgery) ] [ Designated as safety issue: No ]Surgical speciality of physician who performed surgery.
- Percentage of Participants With Infection [ Time Frame: Day 0 (day of surgery) up to 30 days post surgery ] [ Designated as safety issue: No ]Microorganism infection by bacterial type.
- Percentage of Participants Who Showed Clinical Improvement of SSI [ Time Frame: Day 0 (day of surgery) up to 30 days post surgery ] [ Designated as safety issue: No ]Clinical improvement of SSI was defined as healed (signs and symptoms of initial infection resolved) or improved (initial signs and symptoms significantly diminished without the appearance of new signs).
- Percentage of Participants With Post-surgical Drainage [ Time Frame: Day 0 (day of surgery) up to 30 days post surgery ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Percentage of Participants Whose National Nosocomial Infection Surveillance System (NNISS) Scores of Preoperative Risk of Infection Were Greater Than >0 [ Time Frame: Baseline (pre-surgical) ] [ Designated as safety issue: No ]Percentage of participants with NNISS score for increased preoperative risk of infection.
- ASEPSIS Classification in Participants With Serious SSI [ Time Frame: Up to 30 days post surgery ] [ Designated as safety issue: No ]Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of deep tissue, Isolation of bacteria, Stay in hospital prolonged over 14 days (ASEPSIS). ASEPSIS classification is a numerical indication of wound healing progress: satisfactory healing (0-10), disturbance of healing (11-20), minor wound infection (20-30), moderate wound infection (30-40), and severe wound infection (over 40).
- Classification of SSI Infection [ Time Frame: Day 0 (day of surgery) up to 30 days post surgery ] [ Designated as safety issue: No ]Participants with organ-space or deep incisional SSI.
- Percentage of Participants Who Had Microbiologic Resolution of SSI (Sensitivity of Microorganisms to Antibiotics) [ Time Frame: Day 0 (day of surgery) up to 30 days post surgery ] [ Designated as safety issue: No ]Resolution of SSI ranged from eradication (infection cured) to persistence (infection continued).
- Number of Participants With Antimicrobial Resistance [ Time Frame: Day 0 (day of surgery) up to 30 days post surgery ] [ Designated as safety issue: No ]Microbiological resistance reported for microorganisms that were found at a frequency greater (>) than 5 percent (%).

Case
Cases will be defined as patients with elective or emergency abdominal surgery who develop severe surgical site infection (deep incisional or organ cavity type; see Center for Disease Control (CDC) criteria for definition in the Appendix), within 0-30 days of surgery.
|
Procedure: Elective or emergency abdominal surgery
Clinical record review.
|
|
Control
Surgeon-matched controls will be patients with elective or emergency abdominal surgery who are free of surgical site infection (SSI) after 30 days from the surgery.
