The relationship of simplified acute physiology score 3 (SAPS 3) and C-reactive protein (CRP) levels with mortality rates and length of stay of patients in surgical intensive care unit

Abstract

Objectives: The individual risk of surgical patients is more often underestimated and < 15% of patients whounderwent surgery were admitted to ICU. The prognostic scores were developed to assess the mortality rateand prognosis for critical patients including surgical ones. The Acute Physiology and Chronic Health Evaluation(APACHE) score and the Simplified Acute Physiology Score (SAPS) were most popular ones and they wererevised with the improvements in health care opportunities. As a prognostic scoring system SAPS 3’ resultswere defined as excellent in high risk surgical patient study group. CRP is useful as a prognostic indicator oran index of disease progression but its value has not been tested in acute settings adequately. The aim of thisstudy is to test the calibration power of SAPS 3 score and identify correlations between hospital mortality andpatient outcomes with SAPS 3 scores and CRP levels.Methods: This retrospective and analytical study was conducted one year period in surgical ICUs of tertiarylevel of attention in a public institution. It was a case–control medical record review and the patients includedin this study were those who admitted in the surgical ICU for any reason.Results: A total of 806 patients admitted to the Gastroenterological surgical ICU was included in the studybetween March 2016 and March 2017. The relation between mortality rate, length of stay in ICU and SAPS 3score was significant statistically and the relation of CRP levels with SAPS score and mortality rate was foundsignificant statistically.Conclusion: The discriminative power of SAPS 3 score was very good and the calibration was appropriate.
