Proper medication administration in relation to beverage or food is one of the essential tools to achieve the pharmacotherapy goals. It is not known whether this is also considered in the care of inpatients. The aim of this study was to describe and analyse the current practice of medication administration in relation to food and beverages to patients hospitalized in four hospitals in the Czech Republic. This study was conducted based on the results of the first phase of a prospective observation study focused on the safety of medication administration performed by nurses. All data, including the timing of medication administration in relation to food and the data on beverages used, were obtained by the method of direct observation. The team of observersaccompanied the nurse during medication administration. The appropriateness of the medication administration in relationto food/beverages was assessed according to the summary of product characteristics and the published literature. In total, the administration of 5718 oral medications and 198 insulins were analysed. Unproper food timing wasobserved in 15.7% of oral medication administrations and 26.8% of insulin administrations. The highest number ofunproper food timing occurred in the proton pump inhibitors, antihypertensives, and prokinetics. Tea (63.4%) was the most used beverage. Errors with clinically serious impact have been observed in some groups of drugs. The necessity of a systemic approach in management of medication administration is required including interdisciplinary cooperation.
