Nursing Students’ Medication Errors and Adherence to Medication Best-Practice

Background: Nursing students are at risk for committing medication administration errors (MAEs), which significantly alter the delivery of safe and effective healthcare. Purpose: To identify the medications most frequently involved in medication errors as reported by Jordanian nursing students, as well as to identify the level of nursing students’ adherence to best-practice when administering high-risk medications. Methods: A cross-sectional design was used among a convenience sample of 74 nurses. Results: A total of 74 of 110 (67.3%) questionnaires were returned. The most frequent medications subjected to MAEs were Dopamine, Dobutamine, and Insulin continuous intravenous infusion (17.2%, 16.0% and 13.5% respectively). Regarding the adherence to best-practice, nursing students adhered the most to the following best-practices: checking the patient armband prior to medication administration with a mean of 3.81 (±0.6) and bringing the MAR sheet with them when preparing a medication with a mean of 3.46 (±1.1). Conclusion: Developing an effective medication training programs in all undergraduate nursing programs in Jordanis is vital to ensure patient safety. Nursing educators in clinical and academic settings need to reinforce the importance of adherence to medication management best-practice in all courses. Close and effective supervision of students needs to be maintained throughout nursing students’ clinical training, especially during medication preparation and administration.


Introduction
Medication management is a high-risk, high-frequency nursing task in everyday practice [1].It involves the processes of prescription, transcription, dispensing, I. Salami DOI: 10.4236/ojn.2018.85024282 Open Journal of Nursing preparation and administration of medication [2].Providing opportunities for students to become competent in medication management is a core goal of all undergraduate nursing educational programs [3].Medication competence requires a solid knowledge base in pharmacology, mathematical calculation [1], and psychomotor skills in medication preparation [1] [4].Deficiencies in nursing students' medication competence, as well as limited clinical experience significantly increase the risk of medication errors [5].
Medications are part of the patient treatment plan, and appropriate management is critical to ensure patient safety [6].Any medications could cause harm if given in the wrong concentration, at the wrong frequency, or via the wrong route [7].If high-alert medications are given in error, they could cause harm more frequently, therefore increasing patient suffering and maximizing the cost of care [6] [7].Medication error has been defined as any preventable event that may lead to inappropriate use of medication or cause temporary or permanent patient harm [8].
Many international studies have been conducted to measure the incidences, causes and contributing factors to Medication Administration Errors (MAEs) among nursing students.These studies have concluded that the incidence of MAEs among nursing students was surprisingly high and frequently occurred [4] [9] [10].In their cross-sectional survey Cebeci et al. [9] found that 38.8% of nursing students had made at least one MAE during their clinical training.Additionally, they found that the most common cause of MAEs among nursing students was performance deficit, while the most common contributing factor was workload.Other studies found that medication errors committed by students were caused by practicing without full supervision from the bedside registered nurse [11].
In their fourth year of education, undergraduate nursing students at the University of Jordan become more independent in their clinical training and practice without constant supervision from their clinical preceptors.In their last semester, students work 52 shifts in their preferred clinical area shadowing the bedside registered nurses.The transition from directly supervised clinical training to independent self-directed bedside training exposes patients to medication errors committed by nursing students.
Therefore, the aim of this study was to identify the medications most frequently involved in MAEs as reported by Jordanian nursing students.In addition, a secondary objective of this study was to identify the level of nursing students' adherence to best-practice when administering high-risk medications.format from 1 = never to 5 = always to rank their adherence to best-practice when administering high-risk medications, factors that promoted compliance with the protocol, factors that could increase the risk of medication error, the extent of their familiarity with the protocol, and confidence with the protocol [13].A detailed description of the questionnaire used in this research, as well as the psychometric properties including validity and reliability were presented in the research conducted by Salami et al. [13].

Method
Data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 21.0.(SPSS Inc., Chicago, IL, USA).Data were presented using mean, percentage, standard deviation, and proportion for categorical variables.

1) Sociodemographic characteristics
A total of 110 questionnaires were disseminated and 74 of those were returned (67.3% response rate).Table 1 describes the demographic data of the sample.
79.7% of participants were female, their average age was 22.4 (±0.66) and ranged from 22 -24 years old.These nurses did their clinical training in three kinds of hospitals: governmental, teaching, and private hospitals.The highest rate of participation came from students trained in Intensive Care unit (ICU) departments.
2) The most frequent medication involved in MAEs as reported by Jordanian nursing students: Nursing students reported that the medications most frequently subjected to MAEs during medication management (preparing, calculating, mixing, or administering) were Dopamine, Dobutamine, I.V. Insulin, Potassium chloride, Heparin I.V. infusion, S.Q.insulin, Morphine, Amiodarone, Gentamicin and Chemotheray, in respective order of frequency.More details can be found in (Table 2).
3) Adherence to best-practice when administering high-risk medications: Nursing students adhered the most to the following aspects of best-practice: checking the patient armband prior to medication administration with a mean of 3.81 (±0.6) and bringing the MAR sheet with them when preparing a medication (mean 3.46 (±1.1)).One of the primary areas of interest in this study was examining the level to which nursing students adhered to best-practice during the medication management process.However, students also reported participating in practices that increased the risk for medication errors such as: preparing and carrying medications for more than one patient at the same time with a mean of 3.66 (±0.8), and administering medication that another nurse has prepared with a mean of 3.22 (±1.4) (Table 3).

Discussion
This study is the first study conducted on nursing students' MAEs in Jordan.[15] reported a low rate of adherence to checking patient ID prior to medication administration.Additionally, they found that checking patient ID prior to medication administration was highly influenced by many factors such as the nurse's perception of potential harm, type of medication being administered, the nurse's familiarity with the medication or patient, and the age of the patient.Similarly, Dickinson et al. [16] reported that checking patient ID was not always consistent among nurses, even among those working in the same units.This finding was consistent with the result of this study, in which there was a significant number of nursing students who reported noncompliance with this basic safety practice in medication management.b) Bringing the medication sheet (MAR) when preparing the medication The second highest reported practice prior to administering medications was bringing the medication sheet (MAR) when preparing the medication.Even though this practice is an essential part of medication administration protocol, there are still a significant portion of nursing students who are noncompliant with this best-practice protocol.The significance of bringing the MAR sheet to the medication room or patient room prior to medication administration was not investigated in any previous studies.c) Double checking There are very few studies that have investigated the issue of double checking prior to medication administration, and no studies investigated that issue as it relates to nursing students.In this study, there were two items asking nursing students about the practice of double checking: "Do you have unusual doses in-dependently-double checked by another nurse?" and "Do you have insulin doses independently-checked by another nurse?"The level of adherence to these two practices was on the average level of mean 3.06 ± 1 and 3.16 ± 1.0 consecutively.
Again, there are controversies in the literature on the significance of double checking.Armitage [17] reported that double checking may contribute to MAEs because of the checkers' time limitations, and the sense of reduced responsibility in relying on the second nurse.On the other hand, Cohen [18] reported that people checking the work of others will find about 95% of all mistakes.
d) The availability of direct bedside nursing supervision The majority of nursing students in this study reported the absence of a bedside nurse's direct supervision during medication management.This could be explained because nursing instructors from the schools of nursing have a large number of students in the same clinical area or in different scattered areas.Therefore, students may be administering medications on their own, or they may have been given the authority to do so by the bedside registered nurse.This result was not surprising, Reid-Searl et al. [5] reported in their qualitative study on the importance of direct nursing students' supervision that in all cases of medication errors, nursing students reported the absence of required direct supervision.In the same way, Susan [11] reported that the best defense against nursing students' MAEs is the availability of high levels of supervision, guidance, and support that students received from bedside RNs.
2) The most frequent medication involved in MAEs as reported by Jordanian nursing students.
All research studies that have investigated the levels of medication knowledge and MAEs have been conducted on bedside nurses with a wide variety of experiences.No studies were found that have assessed the medications most frequently subjected to MAEs among nursing students.Therefore, the discussion of our results will be compared to results from studies conducted on bedside RNs.
In an investigation of intravenous medication (I.V.) medication error events among critical care nurses, Bagheri-Nesami et al. [19] identified heparin to be the most frequent medication subjected to MAEs (11.5%), followed by insulin (3.8%) in the fourth place, and potassium chloride in the seventh place (3.4%).
Nurses in this study had a working experience of 9.3 ± 5.87 years.In our study, nursing students did not have any previous experience in nursing.They identified dopamine, dobutamine, and insulin I.V. infusion to be the top three medications involved in their MAEs (Table 2).Another survey conducted by the United States Pharmacopoeia (USP) [20] found that insulin was again the number 1 medication (4%) to be misused or mishandled among all healthcare professionals.Potassium chloride (2.2%) was in the third place followed by heparin (1.7%) in the fifth place.

Limitations
Based on the researcher literature search this is the first study to investigate the medication error among Jordanian nursing students.Keeping in consideration that this study was conducted on students studying at the University of Jordan -School of nursing only, other students at other nursing programs in different Jordanian universities were not included in this study.In addition, fear of receiving a low grades may have been contributing to non-reporting the MAEs in some students.Subsequently, the issue of MAEs among Jordanian nursing students may be greater than reported in this study.Finally, the findings must be considered in the context of self-reported recalled medication error during clinical training period, which extends over three years.Therefore, it may not be appropriate to generalize the findings to different educational settings.

Conclusions
The findings of this study suggested that Jordanian nursing students are at high risk of committing MAEs.In addition, it found that noncompliance with medi-
