Potential drug-drug interactions and their risk factors in pediatric patients admitted to the emergency department of a tertiary care hospital in Mexico

Zusammenfassung:Drug-drug interactions (DDIs) detected in a patient may not be clinically apparent (potential DDIs), and when they occur, they produce adverse drug reactions (ADRs), toxicity or loss of treatment efficacy. In pediatrics, there are only few publications assessing potential DDIs and their risk factors. There are no studies in children admitted to emergency departments (ED). The present study estimates the prevalence and describes the characteristics of potential DDIs in patients admitted to an ED from a tertiary care hospital in Mexico; in addition, potential DDI-associated risk factors are investigated. A secondary analysis of data from 915 patients admitted to the ED of the Hospital Infantil de México "Federico Gómez" was conducted. The Medscape Drug Interaction Checker software was used to identify potential DDIs. The results are expressed as number of cases (%), means (95% CI) and medians (25-75th percentiles). Count data regressions for number of total and severity-stratified potential DDIs were performed adjusting for patient characteristics, number of administered drugs, days of stay, presence of ADRs and diagnoses. The prevalence of potential DDIs was 61%, with a median of 4 (2-8). A proportion of 0.2% of potential DDIs was "Contraindicated", 7.5% were classified as "Serious", 62.8% as "Significant" and 29.5% as "Minor". Female gender, age, days of stay, number of administered drugs and diagnoses of Neoplasms (C00-D48), Congenital malformations (Q00-Q99), Diseases of the Blood, Blood-forming Organs and Immunity (D50-D89) and Diseases of the nervous system (G00-G99) were significantly associated with potential DDIs. The prevalence of potential DDIs in the ED is high, and strategies should therefore be established to monitor patients' safety during their stay, in addition to conducting investigations to estimate the real harm potential DDIs inflict on patients.
