EXPLORATORY ANALYSIS BASED ON MIMIC-IV DATABASE AND INVESTIGATION OF FACTORS INFLUENCING THE PROGNOSIS OF ATHLETIC PATIENTS RETURNING TO ICU

Abstract

Objective: To investigate the factors influencing the prognosis of athletic patients returning to ICU. Methods: The clinical data of 76,540 intensive care unit (ICU) admissions in the Medical Information Market Critical Care (MIMIC-IV) database from 2008 to 2019 were retrospectively analyzed. The baseline data of the two groups were compared, and then propensity score matching (PSM) was used to balance the baseline data of the two groups in the in-hospital return group and the unplanned return group, and logistic regression model was used to analyze the prognostic factors of the return athletic patients. Results: The probability of ICU return was increased (P<0.05), the probability of ICU return was increased (P<0.05), and the probability of ICU return was increased (P<0.05). In laboratory tests, the probability of ICU return was also increased (P<0.05), and the rate of ICU return was increased (P<0.05). Heart rate, mean pulsatile pressure, INR, continuous renal replacement therapy, ICU length of stay, chronic obstructive pulmonary disease, atrial fibrillation and 30-day mortality were risk factors for ICU return (OR>1). Urea nitrogen, hemoglobin, dopamine use, and chronic kidney disease were protective factors for ICU return (0R<1). Conclusion: The first ICU admission, ICU length of stay, chronic obstructive pulmonary disease, atrial fibrillation and ICU return are risk factors for ICU return. In hospitalization is to timely pay close attention to these factors, early prevention.
