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.

UNLABELLED: The aim of the study was to identify the reasons for medication administration errors, describe the barriers in their reporting and estimate the number of reported medication administration errors. BACKGROUND: Providing quality and safe healthcare is a key priority for all health systems. Medication administration error belongs to the more common mistakes committed in nursing practice. Prevention of medication administration errors must therefore be an integral part of nursing education. DESIGN: A descriptive and cross-sectional design was used for this study. METHODS: Sociological representative research was carried out using the standardized Medication Administration Error Survey. The research study involved 1205 nurses working in hospitals in the Czech Republic. Field surveys were carried out in September and October 2021. Descriptive statistics, Pearson's and Chi-square automatic interaction detection were used to analyze the data. The STROBE guideline was used. RESULTS: Among the most frequent causes of medication administration errors belong name (4.1 ± 1.4) and packaging similarity between different drugs (3.7 ± 1.4), the substitution of brand drugs by cheaper generics (3.6 ± 1.5), frequent interruptions during the preparation and administration of drugs (3.6 ± 1.5) and illegible medical records (3.5 ± 1.5). Not all medication administration errors are reported by nurses. The reasons for non-reporting of such errors include fear of being blamed for a decline in patient health (3.5 ± 1.5), fear of negative feelings from patients or family towards the nurse or legal liability (3.5 ± 1.6) and repressive responses by hospital management (3.3 ± 1.5). Most nurses (two-thirds) stated that less than 20 % of medication administration errors were reported. Older nurses reported statistically significantly fewer medication administration errors concerning non-intravenous drugs than younger nurses (p < 0.001). At the same time, nurses with more clinical experience (≥ 21 years) give significantly lower estimates of medication administration errors than nurses with less clinical practice (p < 0.001). CONCLUSION: Patient safety training should take place at all levels of nursing education. The standardized Medication Administration Error survey is useful for clinical practice managers. It allows for the identification of medication administration error causes and offers preventive and corrective measures that can be implemented. Measures to reduce medication administration errors include developing a non-punitive adverse event reporting system, introducing electronic prescriptions of medicines, involving clinical pharmacists in the pharmacotherapy process and providing nurses with regular comprehensive training.

BACKGROUND: Medication administration errors (MAE) are a worldwide issue affecting the safety of hospitalized patients. Through the early identification of potential causes, it is possible to increase the safety of medication administration (MA) in clinical nursing. The study aimed to identify potential risk factors affecting drug administration in inpatient wards in the Czech Republic. MATERIAL AND METHODS: A descriptive correlation study through a non-standardized questionnaire was used. Data were collected from September 29 to October 15, 2021, from nurses in the Czech Republic. For statistical analysis, the authors used SPSS vers. 28 (IBM Corp., Armonk, NY, USA). RESULTS: The research sample consisted of 1205 nurses. The authors found that there was a statistically significant relationship between nurse education (p = 0.05), interruptions, preparation of medicines outside the patient rooms (p < 0.001), inadequate patient identification (p < 0.01), large numbers of patients assigned per nurse (p < 0.001), use of team nursing care and administration of generic substitution and an MAE. CONCLUSIONS: The results of the study point to the weaknesses of medication administration in selected clinical departments in hospitals. The authors found that several factors, such as high patient ratio per nurse, lack of patient identification, and interruption during medication preparation of nurses, can increase the prevalence of MAE. Nurses who have completed MSc and PhD education have a lower incidence of MAE. More research is needed to identify other causes of medication administration errors. Improving the safety culture is the most critical challenge for today's healthcare industry. Education for nurses can be an effective way to reduce MAEs by enhancing their knowledge and skills, mainly focusing on increasing adherence to safe medication preparation and administration and a better understanding of medication pharmacodynamics.

Ceramides based on phytosphingosine, sphingosine and dihydrosphingosine are essential constituents of the skin lipid barrier that protects the body from excessive water loss. The roles of the individual ceramide subclasses in regulating skin permeability and the reasons for C4-hydroxylation of these sphingolipids are not completely understood. We investigated the chain length-dependent effects of dihydroceramides, sphingosine ceramides (with C4-unsaturation) and phytoceramides (with C4-hydroxyl) on the permeability, lipid organization and thermotropic behavior of model stratum corneum lipid membranes composed of ceramide/lignoceric acid/cholesterol/cholesteryl sulfate. Phytoceramides with very long C24 acyl chains increased the permeability of the model lipid membranes compared to dihydroceramides or sphingosine ceramides with the same chain lengths. Either unsaturation or C4-hydroxylation of dihydroceramides induced chain length-dependent increases in membrane permeability. Infrared spectroscopy showed that C4-hydroxylation of the sphingoid base decreased the relative ratio of orthorhombic chain packing in the membrane and lowered the miscibility of C24 phytoceramide with lignoceric acid. The phase separation in phytoceramide membranes was confirmed by X-ray diffraction. In contrast, phytoceramides formed strong hydrogen bonds and highly thermostable domains. Thus, the large heterogeneity in ceramide structures and in their aggregation mechanisms may confer resistance towards the heterogeneous external stressors that are constantly faced by the skin barrier.

Dihydroceramides (dCer) are members of the sphingolipid family that lack the C4 trans double bond in their sphingoid backbone. In addition to being precursors of ceramides (Cer) and phytoceramides, dCer have also been found in the extracellular lipid membranes of the epidermal barrier, the stratum corneum. However, their role in barrier homeostasis is not known. We studied how the lack of the trans double bond in dCer compared to Cer influences the permeability, lipid chain order, and packing of multilamellar membranes composed of the major skin barrier lipids: (d)Cer, fatty acids, cholesterol, and cholesteryl sulfate. The permeability of the membranes with long-chain dCer was measured using various markers and was either comparable to or only slightly greater than (by up to 35%, not significant) that of the Cer membranes. The dCer were less sensitive to acyl chain shortening than Cer (the short dCer membranes were up to 6-fold less permeable that the corresponding short Cer membranes). Infrared spectroscopy showed that long dCer mixed less with fatty acids but formed more thermally stable ordered domains than Cer. The key parameter explaining the differences in permeability in the short dCer and Cer was the proportion of the orthorhombic phase. Our results suggest that the presence of the trans double bond in Cer is not crucial for the permeability of skin lipid membranes and that dCer may be underappreciated members of the stratum corneum lipid barrier that increase its heterogeneity.
