Abstract

Abstract Objective: The aim of the this study was to find out the outcome differences in septic shock patients based on the vasopressor dependency index (VDI) value at Dr. Soetomo General Hospital Surabaya. Design: This was an analytical observational research. Setting: Resuscitation Room of Dr. Soetomo General Hospital Surabaya from March to May 2019. This study was approved by the Research Ethics Committee of Dr. Soetomo General Hospital Surabaya. Patients and participants: The inclusion criteria was septic shock patient who met sepsis-3 criteria. There were 44 samples in the inclusion criteria. Interventions: Samples were taken by consecutive sampling. VDI was measured starting from 10 minutes, 1 hour, 6 hours, 12 hours, 24 hours, and 48 hours after the treatment of vasopressor drug. Measurements and results: The most common causes of sepsis was pneumonia (47.7%). Septic shock patients were given norepinephrine (80.0%) as the first line vasopressor drug. There were patient outcome differences within 7 days of treatment based on the VDI value. The VDI value at the 24th hour and the 48th hour were the most influential variable to the patient outcome (p=0.034). The VDI value threshold of the 24th hour was 0.176/mmHg (81.8% sensitivity; 85.2% specificity; 95% CI 0.818-1.000; p=0.000) and of the 48th hour was 0.150/mmHg (88.9% sensitivity; 92.6% specificity; 95% CI 0.859-1.000; p=0.000). Conclusion: There were significant differences in septic shock patient's outcome in the first 7 days of treatment based on VDI value. The VDI value at the 24th hour and the 48th hour were the most influential variables to the patient outcome (p=0.034). The threshold of VDI at the 24th hour was 0.176/mmHg. The threshold value of VDI at 48th hour was 0.150/mmHg.
