    Abstract:
    BACKGROUND: This prospective study compared clinical characteristics and prognosis between primary (P) and secondary (S) acute gastrointestinal injury (AGI) (P-AGI)/(S-AGI) in critically ill patients. METHODS: This was a prospective, single-center observational study. Patients were included if they had been hospitalized for at least 72 h before the AGI diagnosis. Patients were classified according to severity of gastrointestinal dysfunction, while P-AGI or S-AGI were defined according to whether the gastrointestinal system was directly or indirectly involved. Clinical characteristics, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and Sepsis-related Organ Failure Assessment (SOFA) scores after inclusion and 28-day mortality were recorded. RESULTS: Altogether, 282 patients were included: P and S groups enrolled 100 and 182 patients, respectively. The S group patients were older and showed increased morbidities and higher APACHE II and SOFA scores. Compared to the S group, the P group had a higher prevalence in abdominal distention and enteroparalysis and fewer patients at AGI grade I, while more patients at grade III or IV. The S group patients had the higher 28-day mortality. Multiple logistic regression analysis showed AGI grades, APACHE II score, and S-AGI independently predicted the odds of 28-day mortality. CONCLUSIONS: Comparing to the P-AGI patients, the S group patients were older, with higher APACHE II and SOFA scores. AGI grade, APACHE II score, and S-AGI independently predicted the odds of 28-day mortality in AGI patients.
