Keller SC, et al. - Researchers plan this study to improve the understanding of risk factors for and timing of outpatient parenteral antimicrobial therapy (OPAT)-associated adverse drug events (ADEs) to better monitor patients on OPAT. They observe that OPAT-related ADEs were common and often occurred within 2 weeks of hospital discharge. The patients on OPAT are recommended to be monitored more closely for ADEs, including clinical assessment and laboratory monitoring. Monitoring should be performed especially within the first weeks after hospital discharge and particularly among women and patients who receive vancomycin.
