RESUMEN
BACKGROUND: Medication nonadherence is a common problem that leads to increased healthcare utilization. It is unclear how patient insight and attitude towards their medications affect adherence in the ED. Furthermore, it is unclear how perceived medication importance differs between patients and ED physicians. METHODS: We conducted a cross sectional study of adult patients presenting to 2 academic emergency departments from April 2015 to October 2016. Demographic data were collected and questions were asked regarding medication knowledge, perceived importance, and adherence. We also compared perceived importance of medications between patients and two physician raters. Inter-rater agreement was reported as raw percentages, and categorical data were compared using chi-squared analysis. RESULTS: We identified 1268 patients, representing 4634 individual medications. We identified a significant association between knowledge of medications and perceived importance (p < .05). Secondarily, importance level was highly associated with medication adherence (p < .05). When ranking those medications that were considered "least" and "most" important among each patient's med list, our two physicians agreed with patients only 34.1% and 37% of the time respectively, as opposed to 62% and 62.8% agreement between each other. CONCLUSIONS: These data suggest that there is a difference in perceived medication importance between ED physicians and ED patients. Knowledge of a medication's purpose is significantly associated with perceived importance, while this importance appears to be significantly associated with compliance. These results suggest that concerted efforts by ED physicians and staff to educate patients on the utility and importance of their medications may improve adherence.

Ornithine transcarbamylase (OTC) deficiency is a genetic disorder involving a mutation of the ornithine transcarbamylase gene, located on the short arm of the X chromosome (Xp21.1). This makes the expression of the gene most common in homozygous males, but heterozygous females can also be affected and may be more likely to suffer from serious morbidity. Most males present early in the neonatal period with more devastating outcomes than their female counterparts. Up to 34% will present in the first 30 days of life (J Pediatr 2001;138:S30). Females often have partially functioning mitochondria due to uneven distribution of the mutant gene secondary to lyonization ("X-chromosome Inactivation". Genetics Home Reference, 2012). Occasionally, symptomatic females may not even present until they are placed under metabolic stress such as a severe illness, fasting, pregnancy, or new medication (Roth KS, Steiner RD. "Ornithine Transcarbamylase Deficiency". EMedicine, 2012). The urea cycle is the body's primary tool for the disposal of excess nitrogen, which is generated by the routine metabolism of proteins and amino acids. Mitochondrial dysfunction impairs urea production and result in hyperammonemia (Semin Neonatol 2002;7:27). The sine qua non among all degrees of OTC deficiency at presentation is hyperammonemia. As in adults, children will have similar symptoms of encephalopathy, but this may be expressed differently depending on the child's developmental level. We present an unusual case of OTC deficiency in an older child with undifferentiated symptoms of an anticholinergic toxidrome, liver failure, iron overdose, and mushroom poisoning.
