Outcomes prediction score for acute abdomen: a proposal.

ABSTRACT Objective: to establish a correlation between objective data collected at the initial evaluation and the outcomes in cases of acute abdominal pain. Methods: we conducted a retrospective, case-control study in which we reviewed medical records of patients treated at an emergency room in 2016, diagnosed with abdominal and pelvic pain. Results: of the 2,352 medical records evaluated, we considered 330 valid for the study. Of these patients, 235 (71.2%) were discharged and the remaining 95 (28.8%) were hospitalized, submitted to surgery, or died. The statistical analysis demonstrated that male gender, age ≥50, axillary temperature >37.3ºC, anemia, leukocytosis >10,000/mm3, neutrophil count above 7,700/mm3, lymphocyte count less than 2,000/mm3 and hyperamylasemia were variables in independently associated with worse outcome. Conclusion: the presence of three or more of the evaluated variables greatly increases the chances of a patient suffering the outcomes of surgery or death, the chance of death being greater the greater the number of variables present.
