BACKGROUND: Caring for infants on respiratory support is a challenge in the middle-income countries, applying a protocol of targeted oxygen reduction test (tORT) guided by daily assessment of oxygen histograms is novel and practical approach.
OBJECTIVE: To study the impact of tORT guided by daily assessment of oxygen histograms as a quality improvement project aiming to decrease days on oxygen support, and duration of hospital admission in preterm infants.
STUDY DESIGN: A quality project conducted in neonatal intensive care units (NICU) of two hospitals, from 2017- 2018 (Epochs II). After a period of observation of a cohort of preterm Infants, 2016-2017 (Epoch I). The main aims were to reduce days on oxygen and hospital admission days. All infants in Epoch II underwent daily assessment of oxygen histograms and a trial of oxygen reduction if applicable as per a predefined protocol. Comparison was made between these two Epochs, and the primary outcome was the time to successful discontinuation of oxygen support.
RESULTS: Fifty-nine infants were included; 30 underwent the protocolized tORT (Epoch II) with a median (IQR) of 4 (2-6) tORC per infant. Postanal age at presentation (time of initial tORT assessment was performed at the postnatal age of 8 (5, 13) days. Days on oxygen and total numbers of hospital days were significantly less in Epoch II. Oxygen histograms significantly improved after tORT.
CONCLUSIONS: Applying tORT guided by oxygen histograms may have a significant impact on oxygen exposure and hospitalization days of patients admitted to the NICU.
