Reducing Outpatient Infant Blood Draws with Transcutaneous Measurement of Bilirubin

Introduction Newborn jaundice is a common outpatient problem. Transcutaneous bilirubin (TcB) measurements correlate well with total serum bilirubin (SB) measurements below 15 mg/dl and are efficient and noninvasive. Some concern exists that TcB measurement may subsequently lead to an increase in the number of SB measurements performed in the outpatient setting. We aimed to implement the use of a TcB device in an outpatient clinic. By doing so, we sought to increase the number of newborns screened solely by TcB as opposed to SB, by 30%, within 12 months. Methods We conducted plan-do-study-act cycles with targeted interventions to promote the use of TcB in an outpatient clinic for eligible newborns older than 35 weeks gestational age, aged 1-20 days, and without a history of transfusion, phototherapy, extensive bruising, or risk of hemolysis. We used statistical process control methods to measure proportions of newborns evaluated with TcB (run chart) and patients-between SB measurements (G-chart) over time in the outpatient clinic. Results We collected preintervention data for 18-months and intervention data for 12 months. For newborns attending the outpatient clinic, the proportion of TcB measurements increased after implementation of the use of TcB measurement. There was an increase in patients-between SB measurements. At project inception, SB was drawn for every 8 eligible patients. By the end of the project, there were 98 eligible newborns between instances of SB testing. Conclusion Implementation of a quality-improvement initiative to measure TcB in the outpatient clinic was feasible and reduced the number of SB tests.
