Prospective Assessment of Peristomal Infections Using Objective Criteria.

Abstract

Enteral nutrition (EN) is a safe and cost-effective intervention with significant morbidity and mortality benefit that can also be associated with complications. Peristomal infections can occur in 5%-30% of cases after percutaneous endoscopic gastrostomy placement. Despite this common occurrence, widespread use of objective diagnostic criteria is not prevalent, possibly leading to overuse of antibiotics. All patients who were reporting symptoms consistent with peristomal infection were evaluated. Criteria based on erythema, induration, and exudates were applied with cumulative score ≥8 indicating peristomal infection. All patients were followed, with additional factors being collected if available. Forty-three patients noted complaints consistent with peristomal infection. In patients with a score <8 (n = 16), only 2 required antibiotics (12.5%) and 1 patient was hospitalized (6.3%). In patients with a score ≥8 (n = 27), 16 had a score of 8 or 9; all patients responded to antibiotics (100%), and 1 was hospitalized (6.3%). In patients with a score ≥10, all (100%) were treated with antibiotics. Five of 11 (45%) patients were hospitalized, with the most common diagnosis being sepsis. Of the baseline variables analyzed, higher body mass index correlated with score ≥10 (26.36 ± 2.94 vs 22.91 ± 4.35 in score <9, P = .0128). Objective criteria were effective in risk stratifying patients who presented with reports of peristomal infection. Patients with a score <8 tended to be at low risk, scores of 8-9 were of moderate risk, and patients with a score ≥10 were at high risk and required very close monitoring or hospitalization.
