An Initiative to Decrease Laboratory Testing in a NICU.

BACKGROUND AND OBJECTIVES: Laboratory testing is performed frequently in the NICU. Unnecessary tests can result in increased costs, blood loss, and pain, which can increase the risk of long-term growth and neurodevelopmental impairment. Our aim was to decrease routine screening laboratory testing in all infants admitted to our NICU by 20% over a 24-month period. METHODS: We designed and implemented a multifaceted quality improvement project using the Institute for Healthcare Improvement's Model for Improvement. Baseline data were reviewed and analyzed to prioritize order of interventions. The primary outcome measure was number of laboratory tests performed per 1000 patient days. Secondary outcome measures included number of blood glucose and serum bilirubin tests per 1000 patient days, blood volume removed per 1000 patient days, and cost. Extreme laboratory values were tracked and reviewed as balancing measures. Statistical process control charts were used to track measures over time. RESULTS: Over a 24-month period, we achieved a 26.8% decrease in laboratory tests performed per 1000 patient days (∽51 000 fewer tests). We observed significant decreases in all secondary measures, including a decrease of almost 8 L of blood drawn and a savings of $258 000. No extreme laboratory values were deemed attributable to the interventions. Improvement was sustained for an additional 7 months. CONCLUSIONS: Targeted interventions, including guideline development, dashboard creation and distribution, electronic medical record optimization, and expansion of noninvasive and point-of-care testing resulted in a significant and sustained reduction in laboratory testing without notable adverse effects.

A novel and accurate method for estimating umbilical arterial and venous catheter insertion length.

OBJECTIVE: To develop a novel, rapid, and more accurate model for estimating umbilical arterial (UAC) and venous catheter (UVC) insertion length. STUDY DESIGN: We evaluated UACs and UVCs from a retrospective cohort to determine the rate of correct initial positioning based on conventional birth weight-based equations utilized in our neonatal intensive care unit. We then derived new equations, developed the mobile application, UmbiCalc, to simplify implementation of the new equations, and validated their accuracy with prospective utilization. RESULTS: The conventional equations successfully predicted insertion length in 69% (364 of 524) of UACs and only 36% (194 of 544) of UVCs. Our new model was prospectively applied to 68 UAC and 80 UVC placements with successful initial positioning achieved in 90% [95% CI, 80.2-94.9] and 76% [95% CI, 65.9-84.2], respectively. CONCLUSIONS: Our novel approach more accurately estimates UAC and UVC insertion length.

Is Extracorporeal Membrane Oxygenation for a Neonate Ever Ethically Obligatory?

Certain interventions in the neonatal intensive care unit are considered ethically obligatory, and should be provided over parental objections. After reviewing a case, comparative outcome data, and relevant ethical principles, we propose that extracorporeal membrane oxygenation for meconium aspiration syndrome may, in some cases, be an ethically obligatory treatment.

Perinatal onset mevalonate kinase deficiency.

Defects in mevalonate kinase, a critical rate-limiting enzyme in cholesterol and isoprene metabolism, have been associated with 2 clinical phenotypes: mevalonic aciduria, which presents in infancy or early childhood with growth failure, dysmorphic features, and neurologic disease; and hyperimmunoglobulinemia D and periodic fever syndrome, which usually presents outside the neonatal period as an autoinflammatory periodic fever syndrome. This report describes a kindred with 2 siblings affected by severe mevalonate kinase deficiency (mevalonic aciduria) with perinatal onset. Dysmorphic and central nervous system abnormalities, anemia, and cholestasis were prominent features in 1 sibling. Both cases were fatal, 1 in the immediate neonatal period and 1 in utero. The small number of cases of mevalonate kinase deficiency presenting in the perinatal period have typically been severely affected, with signs and symptoms of a severe multisystem disorder. Predominant features of perinatal onset mevalonate kinase deficiency include intrauterine growth restriction, cerebral ventriculomegaly, dysmorphic features, skeletal abnormalities, dyserythropoietic anemia with extramedullary erythropoiesis, thrombocytopenia, cholestatic liver disease, persistent diarrhea, renal failure, recurrent sepsis-like episodes, and failure to thrive. Clinical findings may mimic severe intrauterine viral infection, a chromosomal abnormality, or an acute sepsis syndrome, potentially contributing to delays in diagnosis of this rare condition. Perinatal onset mevalonate kinase deficiency is associated with a very poor prognosis, with death in utero or in early infancy. Detailed autopsy findings in mevalonate kinase deficiency have rarely been reported.

Attending physician work hours: ethical considerations and the last doctor standing.

Based at least in part on concerns for patient safety and evidence that long shifts are associated with an increased risk of physician error, residents' and fellows' work hours have been strictly limited for the past several years. Little attention has been paid, however, to excessive attending physician shift duration, although there seems to be no reason to assume that this common practice poses any less risk to patients. Potential justifications for allowing attending physicians to work without hourly limits include physician autonomy, workforce shortages in certain communities or subspecialties, continuity of care, and financial considerations. None of these clearly justify the apparent increased risk to patients, with the exception in some settings of workforce shortage. In many hospital settings, the practice of allowing attending physicians to work with no limit on shift duration could pose an unnecessary risk to patients.
