At the Dekalb Medical Center at the Neonatal Intensive Care Unit (NICU), Heel Stick, a small procedure used to measure blood glucose (BG) by pricking the heel, is often performed on newborns (Vedder, & Sawyer, 2015). Also, at the Special Care Nursery (SCN), the Accu-Chek, a hand-held device that calculates the BG level is performed to check the BG level of neonates. In exposure to these two methods of BG intake, the accuracy in analyzing BG in both tests is of interest. Through research and review of literature, this paper will explore the methodology and accuracy of both BG tests and describe why this variety exists. According to the US National Library of Medicine (NML), National Institutes of Health (NIH) (2006), most health care settings …show more content…

Particularly, such tests are performed to examine immediate neonatal hypoglycemia on high-risk newborns, such as babies born with low birth weight, small for gestational age, large for gestational age, and asphyxia. Based on the current evidence-based practice, this kind of testing is not consistent in newborns and is prone to occurrence of sample or performance errors (NML/NIH, 2006). Even though there are some discrepancies, Accu-Chek is often used in NICU because it is a point of care test (POCT), requires small volume of blood, and the result can be obtained within 5-10 seconds. On the other hand, the Heel Stick is performed on newborns to measure BG levels and newborn screenings, which yield accurate readings by sending it to laboratory. According to Vedder, et al. (2015), the Heel Sticks are discouraged in newborn patients if there …show more content…

The study done on the POCT glucose meter shows that evaluating the venous blood from 600 patients from different NICU achieved less desired degree of accuracy and exactness. In this study, 98.8% of the Accu-Chek glucose meter’s value range within ±20 mg/dl of the average laboratory analysis values (Joseph, 2013). A study done by Nuntnarumi, Chittamma, Pongmee & Goonthon (2011) revealed Accu-Chek, has mean bias of 95%, test discrepancy of 78%, and BG test result within 20% of the laboratory analyzer value. Another research done to check the accuracy of Accu-Chek along with other two BG measuring meters devices discovered errors and inaccuracy on 4 out of 155 newborn infants that have incidence of hypoglycemia (Thomas, Signal, & Harris, 2014). This illustrates that accuracy on determining the hypoglycemic events on newborns could lead to discrepancies on using these POCT devices in hospitals. The evidence-based practice research done by Harris, Weston, Battin, & Harding (2014), discussed the importance of doing heel stick, which is more accurate and reliable than any other methods. In his research, 180 surveys were sent and 127 (71%) responded the survey. Most of the responders (126 out of 127, 99%) reported that BG of newborn was measured using heel stick sampling during hospital stay. These level III nurseries have protocols to prevent hypoglycemia whose blood glucose are <40
