The need for PGY2-trained clinical pharmacy specialists.

The American College of Clinical Pharmacy and other stakeholder organizations seek to advance clinical pharmacist practitioners, educators, and researchers. Unfortunately, there remains an inadequate supply of residency-trained clinical specialists to meet the needs of our health care system, and nonspecialists often are called on to fill open specialist positions. The impact of clinical pharmacy specialists on pharmacotherapy outcomes in both acute care and primary care settings demonstrates the value of these specialists. This commentary articulates the need for postgraduate year two (PGY2)-trained clinical specialists within the health care system by discussing various clinical and policy rationales, interprofessional support, economic justifications, and their impact on quality of care and drug safety. The integrated practice model that has grown out of the American Society of Health-System Pharmacists Pharmacy Practice Model Initiative (PPMI) could threaten the growth and development of future clinical specialists. Therefore, the ways in which PGY2-trained clinical pharmacist specialists are deployed in the PPMI require further consideration. PGY2 residencies provide education and training opportunities that cannot be achieved in traditional professional degree programs or postgraduate year one residencies. These specialists are needed to provide direct patient care to complex patient populations and to educate and train pharmacy students and postgraduate residents. Limitations to training and hiring PGY2-trained clinical pharmacy specialists include site capacity limitations and lack of funding. A gap analysis is needed to define the extent of the mismatch between the demand for specialists by health care systems and educational institutions versus the capacity to train clinical pharmacists at the specialty level.

MRI patterns in prolonged low response states following traumatic brain injury in children and adolescents.

OBJECTIVES: To explore the relationship between location and pattern of brain injury identified on MRI and prolonged low response state in children post-traumatic brain injury (TBI). METHODS: This observational study compared 15 children who spontaneously recovered within 30 days post-TBI to 17 who remained in a prolonged low response state. RESULTS: 92.9% of children with brain stem injury were in the low response group. The predicted probability was 0.81 for brain stem injury alone, increasing to 0.95 with a regional pattern of injury to the brain stem, basal ganglia, and thalamus. CONCLUSIONS: Low response state in children post-TBI is strongly correlated with two distinctive regions of injury: the brain stem alone, and an injury pattern to the brain stem, basal ganglia, and thalamus. This study demonstrates the need for large-scale clinical studies using MRI as a tool for outcome assessment in children and adolescents following severe TBI.

Clinical experience with spironolactone in pediatrics.

BACKGROUND: In 2003, the Food and Drug Administration placed spironolactone on its list of drugs needing pediatric studies. OBJECTIVE: To describe the use of spironolactone in a large group of children and evaluate its safety, focusing on its effects on potassium. METHODS: A prospective observational study was conducted. Patient demographic information was collected, as well as dosing regimens, use of other medications, and potassium concentrations. Patients were grouped by diagnosis. Comparisons were made with unpaired t-tests. RESULTS: One hundred consecutive patients were evaluated. The average age was 20.8 months and weight was 9.5 kg. Sixty-two patients had heart disease (HD), 29 had chronic lung disease (CLD), and 9 had other conditions. The initial dose was 1.8 +/- 0.7 mg/kg/day. Patients with CLD received a higher dose than those with HD (2 +/- 0.8 vs 1.7 +/- 0.5 mg/kg/day; p = 0.04). Sixty-six patients received furosemide and 37 received thiazides (12 received both). The average potassium concentration after initiation was 4.3 +/- 0.8 mEq/L, with higher values in patients with CLD versus HD (4.7 +/- 0.7 vs 4.2 +/- 0.7 mEq/L; p = 0.007). Twenty-six patients required potassium supplementation, including 16 with CLD and 8 with HD; no other adverse effects were noted. Average length of treatment was 16 days, with a length of stay of 38 days. Of the 92 patients surviving to discharge, 66 continued on spironolactone. CONCLUSIONS: This sample demonstrates that spironolactone is a common component of diuretic regimens in pediatric patients. The only adverse effects were alterations in potassium. While hyperkalemia was more common initially, hypokalemia was more frequent with long-term use. Potassium concentrations should be carefully monitored, particularly in children receiving multiple diuretics. Additional research is needed to define the pharmacokinetics and optimal dosing interval of spironolactone, as well as determine its long-term effects on potassium.
