Combined Predictive Value of RSBI and CALLY Index in Predicting Weaning Success in ICU Patients

Sponsor: Istanbul University - Cerrahpasa

Summary

The primary objective of this prospective observational study is to evaluate the effectiveness of combining the Rapid Shallow Breathing Index (RSBI) and the CALLY index to predict weaning success in adult patients within the intensive care unit. While weaning from mechanical ventilation is a critical clinical step, existing physiological metrics like RSBI do not fully capture a patient's inflammatory or nutritional status. This research introduces the CALLY index calculated as the ratio of the patient's immuno-nutritional reserve (Albumin and Lymphocytes) to systemic inflammation (CRP) as a complementary metabolic marker. By tracking approximately 105 participants at Basaksehir Cam and Sakura City Hospital, the study monitors weaning success over both a 48 hour and a 7 day period to identify both immediate and late phase extubation failures. The ultimate goal is to provide a more holistic prediction model that potentially reduces re-intubation rates and improves clinical outcomes by accurately identifying the optimal time for ventilator removal.
