RESUMO
BACKGROUND: Our objective was to assess in non-critically-ill adult inpatients receiving parenteral nutrition (PN) the risk of developing liver function test (LFT) alterations when receiving concomitant possibly hepatotoxic medications or others reported to improve LFTs during PN. METHODS: A multicenter retrospective analysis of prospectively collected data was performed on patients receiving PN. Two groups were recruited: group LALT (patients with any LFT alterations during PN), and group NOLALT (patients without such alterations). Exclusion criteria were previous sepsis, shock, renal failure, hyperglycemia, LFT alteration, or biliopancreatic surgical procedures. Medications were classified into 2 categories: medications reported to improve LFTs during PN (n = 8) and possibly hepatotoxic medications (n = 54), including a subgroup of possibly highly hepatotoxic medications (n = 30). RESULTS: The study included 200 patients, 136 (68.0%) in the LALT group. The groups differed in the number of patients requiring surgical intervention ≤7 days before PN (LALT, 94 [69.1%]; NOLALT, 29 [45.3%]; P < .002) and those receiving possibly hepatotoxic medications (LALT, 126 [92.6%]; NOLALT, 45 [70.3%]; P < .001). Variables in the final Cox regression model were possibly hepatotoxic medications, odds ratio (OR) 3.310 (1.678-6.530); surgical intervention prior to PN, OR 1.861 (1.277-2.711); baseline triglyceridemia, OR 1.005 (1.001-1.009); and creatinine, OR 1.861 (1.043-3.323). CONCLUSIONS: Patients who received PN and concomitantly possibly hepatotoxic medications had a 3-fold risk of developing LFT alterations. Medications reported to improve LFTs had no effect. The use of possibly hepatotoxic medications during PN was associated with LFT alterations.

OBJECTIVE: The biochemical test validation process of parenteral nutrition bags is described to verify the correct composition of critical compounds before its administration, as well as its impact on safety after two years since its implantation in a population of premature infants. METHOD: For the validation of the technique, 35 samples of parenteral nutrition without lipids were processed by the emergency laboratory, following the routine procedures used to measure the concentrations of glucose and electrolytes in plasma and urine. To analyze its impact on safety, pre-implantation and post- implantation risk analysis was carried out using failure mode, effects and criticality analysis (FMECA). Likewise, all out-of-range results and their potential repercussions on patient safety were evaluated. RESULTS: Regression analysis showed no systematic measurement error for glucose, calcium and potassium; however, there is a constant systematic error for sodium and magnesium, thus both were discarded for routine analysis. Failure mode, effects and criticality analysis results showed a decrease in the risk of the process of 11% for the biochemical test. We tested 1,734 parenteral nutritions from 218 premature neonates; 58 (3.3%) results were out of the acceptance range, and 7 were considered to be potentially dangerous compounding errors. CONCLUSIONS: The biochemical test of glucose and electrolytes is an efficient and reproducible method that prevents possible compounding errors from reaching the patient.
Objetivo: Se describe el proceso de validación del control bioquímico de las bolsas de nutrición parenteral para verificar la correcta composición de ingredientes críticos antes de la administración, así como su impacto en la seguridad tras dos años desde la implantación en una población de recién nacidos prematuros.Método: Para la validación de la técnica se usaron 35 muestras de nutrición parenteral sin lípidos, que se procesaron en el laboratorio de Urgencias, siguiendo los procedimientos rutinarios utilizados para medir las concentraciones de glucosa y electrolitos en plasma y orina. Para analizar su impacto en la seguridad se realizaron análisis pre y post implantación mediante análisis modal de falla, efectos y criticidad. También se evaluaron los resultados fuera de rango y sus potenciales repercusiones en la seguridad del paciente.Resultados: El análisis de regresión no muestra error sistemático de medida para glucosa, calcio y potasio; en cambio, para el sodio y el magnesio sí existe un error sistemático, por lo que ambos fueron descartados para los análisis rutinarios. Los resultados del análisis modal de fallos y efectos, atribuibles a la implantación del control bioquímico, mostraron una disminución del riesgo del proceso del 11%. Se analizaron 1.734 nutriciones, correspondientes a 218 neonatos prematuros; se encontraron 58 (3,3%) resultados fuera del rango de aceptación, de los cuales 7 se consideraron errores de preparación potencialmente peligrosos.Conclusiones: El control bioquímico de glucosa y electrolitos es un método eficiente y reproducible que evita que posibles errores de preparación afecten al paciente.

OBJECTIVE: this study assessed the incidence of hyperglycemia, hypertriglyceridemia, and liver function test (LFT) alterations among patients older and younger than 65 years receiving parenteral nutrition (PN). A secondary objective was to compare the incidence of any of these three events. MATERIAL AND METHODS: inclusion criteria were non-critically ill adult inpatients receiving PN for ≥ 7 days in 15 hospitals in Spain. Exclusion criteria were hyperglycemia, hypertriglyceridemia, LFT alterations, sepsis, shock, pancreatic/hepatobiliary surgery, renal failure, diabetes mellitus (DM) type 1, insulin-treated DM type 2, acute DM complications, or obesity prior to PN. Patients were classified into groups YOUNG (aged 35-64) and OLD (aged 65-95). RESULTS: this study recruited 200 patients. Group YOUNG included 63 (31.5%) patients and OLD, 137 (68.5%). Hyperglycemia appeared in 37 (18.5%) patients, eight (12.7%) in group YOUNG and 29 (21.2%) in group OLD (p = 0.174). Hypertriglyceridemia appeared in only one (0.7%) patient. LFT alterations appeared in 141 (70.5%) patients, 44 (69.8%) in group YOUNG and 97 (70.8%) in group OLD (p = 1.000). The model for hyperglycemia included DM type 2, previous surgical procedure, and use of hyperglycemia-inducing medications. The model for LFT alteration included previous surgical procedure, amount of lipids and amino acids, medications causing LFT alterations and a trend for age group. The model for any event included surgical procedure, DM type 2, and medications causing alterations. CONCLUSION: patients of ≥ 65 years receiving PN had similar incidences of hyperglycemia, hypertriglyceridemia, and LFT alterations as younger patients. Additionally, older patients had trends toward lower LFT alterations.
