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.
