Clinical pathway for pediatric parenteral nutrition.

The nutrition support team at Lucile Salter Packard Children's Hospital at Stanford developed a clinical pathway for infants and children receiving parenteral nutrition (PN). Use of clinical pathways for health care delivery is one way in which clinicians and institutions are responding to pressure from managed care organizations to reduce costs and maintain or improve quality. This pathway was developed to standardize the process for ordering, implementing, and monitoring PN. Specific goals for the pathway are as follows: to decrease the number of patients receiving PN inappropriately, to decrease the duration of PN for those patients who require it, to determine complication rates, and to monitor outcomes of therapy. Such comprehensive monitoring will help identify areas for improvement. By developing and implementing action plans to address these issues, we expect to improve continuously the processes and outcomes associated with PN therapy.

Medication error prevention by clinical pharmacists in two children's hospitals.

The purpose of this study was to record prospectively the frequency of and potential harm caused by errant medication orders at two large pediatric hospitals. The objective of the study was to assess the impact of pharmacist intervention in preventing potential harm. The study was conducted during a 6-month period. A total of 281 and 198 errors were detected at the institutions. The overall error rates for the two hospitals were 1.35 and 1.77 per 100-patient days, and 4.9 and 4.5 per 1,000 medication orders, respectively. Pediatric patients aged 2 years and less and pediatric intensive care unit patients received the greatest proportion of errant orders. Neonatal patients received the lowest rate of errant orders. The most common type of error was incorrect dosage, and the most prevalent type of error was overdosage. Antibiotics was the class of drugs for which errant orders were most common. Orders for theophylline, analgesics, and fluid and electrolytes, including hyperalimentation, were also frequently in error. In general, the error rate was greatest among physicians with the least training, but no physician group was error free. Involving pharmacists in reviewing drug orders significantly reduced the potential harm resulting from errant medication orders.

Calcium and phosphorus in neonatal parenteral nutrition solutions.

Due to calcium and phosphorus solubility problems in parenteral nutrition solutions, it is difficult to provide the premature infant with enough of these two minerals for adequate bone mineralization. In order to determine the maximum amounts of both Ca and P soluble in neonatal parenteral nutrition solutions, we employed the following procedure: (1) using concentrations of dextrose 10 to 25% and amino acid 0.5 to 4.0% with standard electrolyte and vitamin concentrations, Ca and P additions were sequentially made to determine the critical concentrations at which precipitates formed; (2) the pH of each test solution was determined; (3) all test solutions were incubated for 30 hr at room temperature; (4) following incubation, all tests were visually observed for calcium-phosphate crystals; (5) the solutions not obviously precipitated were filtered using black Millipore filters to determine the presence of any microprecipitates. Multiple graphs of Ca and P solubility in various dextrose/amino acid solutions were prepared from data generated by the study. The Ca and P interaction is primarily pH sensitive. Factors affecting the solution pH include both dextrose and amino acid concentrations. Our study showed that increases in amino acid concentrations enabled us to increase both Ca and P in the solutions.
