Persistent patency of the ductus arteriosus is a major cause of morbidity and mortality in premature infants. In infants born prior to 28 weeks of gestation, a hemodynamically-significant patent ductus arteriosus (PDA) can cause cardiovascular instability, exacerbate respiratory distress syndrome, prolong the need for assisted ventilation, and increase the risk of bronchopulmonary dysplasia, intraventricular hemorrhage, renal dysfunction, intraventricular hemorrhage, cerebral palsy, and mortality. In this article, we review the pathophysiology, clinical features, and assessment of hemodynamic significance, and provide a rigorous appraisal of the quality of evidence to support current medical and surgical management of PDA of prematurity. Cyclo-oxygenase inhibitors such as indomethacin and ibuprofen remain the mainstay of medical therapy for PDA, and can be used both for prophylaxis as well as rescue therapy to achieve PDA closure. Surgical ligation is also effective and is used in infants who do not respond to medical management. Although both medical and surgical treatment have proven efficacy in closing the ductus, both modalities are associated with significant adverse effects. Because the ductus does undergo spontaneous closure in some premature infants, improved and early identification of infants most likely to develop a symptomatic PDA could help in directing treatment to the at-risk infants and allow others to receive expectant management.

The objective of this study is to determine the safety and efficacy of an extended interval aminoglycoside dosing guideline implemented in our neonatal intensive care unit (NICU). A retrospective review of pharmacokinetic data on 44 patients led to the development of an extended interval aminoglycoside guideline utilizing a 5-mg/kg dose given at an interval based on postconceptional age and risk factors that may alter aminoglycoside clearance. After implementation of the new clinical guideline, a retrospective review of patient records was performed. Thirty-six of 43 peak levels were within the goal range. Trough levels were <1 microg/mL in 41 of 46 patients, with no trough >2 microg/mL. Thirty-three patients had clinical or culture proven sepsis and were successfully treated with the new regimen. No difference between pre- and post-treatment blood urea nitrogen (BUN) and serum creatinine values was observed. Hearing evaluations were performed in 32 patients with one failure. The patient who failed the hearing screen, passed a follow-up hearing test. Three deaths, none attributed to infection or the drug, occurred during the evaluation period. The dosing guidelines developed for our NICU patients are safe and effective, although evaluation of the longterm potential for ototoxicity should be performed.

Most of the clinical track pharmacy faculty indicated that they have insufficient time to fulfill their nonclinical academic responsibilities. Provision of protected time may alleviate some of these time constraints.

OBJECTIVES Assess the competency of community pharmacists in identifying errors in pediatric prescriptions and to determine how often pharmacists perform interventions known to mitigate the likelihood of error. The study sought to recognize factors that may impact the pharmacist's ability to identify and mediate these errors, and to detect barriers that limit the role of the pharmacist pediatric patient care. METHODS A survey was distributed through the University of Illinois at Chicago College of Pharmacy Alumni Network and the Illinois Pharmacists Association email listservs. Pharmacists practicing in a retail setting within the last 5 years were included. Three prescription scenarios for commonly used pediatric medications with corresponding questions were created to assess a pharmacist's ability to identify errors. Demographics pertaining to the pharmacist and the practice site, as well as information about dispensing practices, were collected. Logistic regression was used to identify factors that might impact the pharmacists' ability to identify errors. RESULTS One hundred sixty-one respondents began the survey and 138 met inclusion criteria. In 15% to 59% of scenario-based questions, pharmacists did not appropriately identify errors or interventions that would decrease the likelihood of error. Correct identification of doses was associated with total prescription volume in one scenario and with pediatric prescription volume in another scenario. Pharmacists did not consistently label prescriptions for oral liquids in milliliters or dispense oral syringes. Barriers to pharmacist involvement included availability and interest of the caregiver, ability to contact prescriber, and pharmacy staffing. CONCLUSION Community pharmacists did not consistently identify medication errors or use interventions known to mitigate error risk.
