Background: Electronic Prescribing and Medicines Administration (EPMA) systems are being widely implemented to facilitate medication safety improvement. However, translating the resulting big data into actionable knowledge has received relatively little attention.Objective: To use routinely collected EPMA data in the study of exact time discrepancy between physicians' order and nurses' administration of systemic antibiotics. We evaluated first and follow-up dose administration and dose intervals and examined multi-factorial determinants in ordering and administration explaining potential discrepancy.
Methods:We conducted an observational study of electronic health records for all medical patient stays with antibiotic treatment from January to June 2018 (n=4392) in a large Belgian tertiary care hospital. Using an EPMA system with Barcode Medication Administration, we calculated time discrepancy between order and administration of first doses (n=6233), followup doses (n=87 960) and dose intervals. Multiple logistic regression analysis estimated the association between time discrepancy and various determinants in ordering and administration.Results: Time discrepancy between physician order and nurse administration was less than 30 minutes for 48.7% of first doses and 61.7% of follow-up doses with large variation across primary diagnoses. Greater dose intervals, oral versus intravenous administration, and order diversion from regular nurse administration rounds showed strongest association with less timely administration.
Conclusion:Electronic Prescribing and Medicines Administration systems show huge potential to generate actionable knowledge. Concerning antibiotics treatment, having physicians' orders coincide with regular nurse administration rounds whenever clinically appropriate, 4 further taking contextual factors into account, could potentially improve antibiotics administration timeliness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
