Medication Administration Error and its Associated Factors Among Nurses in a Tertiary Hospital, Southeast Nigeria.. Online Journal of Health and Allied Sciences. 2025 Mar; 24(93): 1-70972-5997https://imsear.searo.who.int/handle/123456789/252879Errors in the administration of medications can have serious consequences and put patients' safety in danger Despite this, there remained a dearth of information on this topic in the south-east of Nigeria. This study aimed to identify the frequency, types, and factors linked to medication administration errors (MAE) among nurses working in tertiary institutions in south-eastern Nigeria. This cross-sectional study surveyed a total of 251 Nurses. The data were collected with a questionnaire and analysed using descriptive and inferential statistics. The mean and standard deviation were used for the 4-point scale items that assessed the influencing factors on MAEs and a mean (M) >2.5 was judged to be an influencing factor. Chi-Square test/Fisher's exact test were used to test for significant association between demographic characteristics and medication administration error at a 5% level of significance. The findings revealed that most (86.5%) of the respondents had administered medications incorrectly. The major nurse-related MAEs were a misidentification of drugs (2.71 ±1.00) and poor drug storage (2.70 ±0.90) were the major institutional factors. No significant association was found between medication administration error and the demographic characteristics: age (p = .376), gender (p = .647), rank (p = .067), working experience (p = .141), and highest academic qualification (p = .373). There is a high occurrence of MAEs among the nurses in this study. As a result, it should be a top priority to regularly provide training on medication safety procedures and updates on new guidelines.Medication administration errorNursesFactors associated with MAEsJournal ArticleIndiaDepartment of Nursing Sciences, College of Medicine, University of Nigeria, Enugu Campus, NigeriaDepartment of Nursing Sciences, College of Medicine, University of Nigeria, Enugu Campus, NigeriaDepartment of Nursing Sciences, College of Medicine, University of Nigeria, Enugu Campus, NigeriaDepartment of Nursing Sciences, College of Medicine, University of Nigeria, Enugu Campus, NigeriaDepartment of Nursing Sciences, College of Medicine, University of Nigeria, Enugu Campus, NigeriNew Life Statistics, Enugu, State Nigeria.
