Nurses' Perceived Causes of Medication Administration Errors: A Qualitative Systematic Review

Experiences of clinical nurses with medication interruption: A systematic review and qualitative meta-synthesis

BACKGROUND

Managing medication interruptions is considered one of the biggest dilemmas for nurses in clinical settings. To improve medication safety, it was imperative to conduct a systematic review to get a deeper understanding of nurses' experiences with medication interruptions.

AIMS

A systematic review and qualitative meta-synthesis aimed to explore clinical nurses' experiences of interruption during medication in hospitals.

METHODS

Systematic searches were conducted in PubMed, CINAHL, Ovid Medline, Embase, Web of Science, and The Cochrane Library from inception to January 2024. The search strategy included four groups of keywords: (1) qualitative research, (2) nurses, (3) medication interruption, and (4) experience. Critical Appraisal Skills Programme was used to assess the quality of the studies. Meta-ethnography was utilized to synthesize the findings of the included studies.

RESULTS

Nine articles published between 2012 and 2023 were included; the number of participants varied from 5 to 40, aged 20-68 years, and the majority were female. Four synthesized findings were identified as follows: (1) an inevitable part of the routine, (2) a decision-making process, (3) working in a minefield, and (4) coping with interruption.

LINKING EVIDENCE TO ACTION

Nurses embraced interruptions as an inherent component of clinical care. Previous experience and nursing culture, encompassing personal and professional aspects, significantly influence nurses' attitudes toward medication interruptions. It is crucial to incorporate the distinctive work experiences of nurses into techniques aimed at efficiently handling interruptions in future research. The registration number in PROSPERO is CRD42023470276.

Analysis of the Incidence and Factors Influencing Medication Administration Errors Among Nurses: A Retrospective Study

AIMS

To explore the incidence and factors influencing medication administration errors (MAEs) among nurses.

BACKGROUND

Medication administration is a global concern for patient safety. Few studies have assessed the incidence of MAEs or explored factors that considered the interplay between behaviour, the individual and the environment.

METHODS

This retrospective study included 342 MAEs reported in the electronic nursing adverse event reporting system between January 2019 and September 2023 at a university-affiliated teaching hospital in China. Data on nurses' demographics and medication administration were extracted from the nursing adverse event reports. The reports were classified according to the severity of patient harm. The causes of the 342 MAEs were retrospectively analysed using content analysis based on Bandura's social cognitive theory. Descriptive statistics were used to calculate the proportion of medication errors and the distribution of subcategories.

RESULTS

In total, 74.3% of MAEs were adverse events owing to mistakes and resulted in no harm or only minor consequences for patients. Nurses aged 26-35 years and those with 6-10 years of experience were the most common groups experiencing MAEs. Factors influencing MAEs included personal ('knowledge and skills' and 'physical state'), environmental ('equipment and infrastructure,' 'work settings' and 'workload and workflow') and behavioural ('task performance' and 'supervision and communication') factors. The study further highlighted the interrelationships among personal, behavioural and environmental factors.

CONCLUSION

Multiple factors influence MAEs among nurses. Nurse-related MAEs and the relationship between behaviours, individual factors and the environment, as well as ways to reduce the occurrence of MAEs, should be considered in depth.

RELEVANCE TO CLINICAL PRACTICE

Understanding the factors influencing MAEs can inform training programs and improve the clinical judgement of healthcare professionals involved in medication administration, ultimately improving patient prognoses and reducing MAEs.

PATIENT OR PUBLIC CONTRIBUTION

The findings can help develop clinical guidelines for preventing MAEs.

Addressing Medication Administration Safety Through Simulation: A Quasi-Experimental Study Among Nursing Students

Healthcare institutions are dedicated to minimizing medication errors and promoting their reporting. This study investigates the impact of simulation on nursing students' attitudes toward and intention to report medication errors. A quasi-experimental one-group pre-post-test study was conducted. Third-year nursing students (N = 63) participated in a scenario-based simulation for medication administration. Participants' errors were documented. Participants self-reported attitudes toward medication administration safety and intention to report errors. The most reported error was "contraindicated in disease" (61%). The simulation increased attitudes of preparedness by the training program received (p < 0.01) and belief in the patient's involvement in preventing errors (p < 0.01), and decreased the belief that professional incompetence reveals errors (p = 0.015). Intention to report errors was influenced by medication error training received (p = 0.045), confidence in error reporting (p < 0.001), and a sense of responsibility to disclose errors (p = 0.001). Simulation effectively shapes attitudes and intentions regarding medication error reporting. Improving nursing students' awareness, skills, and clinical judgment can foster a safety culture and potentially reduce patient harm. Future research should examine the long-term effects of simulation and its impact on reducing medication errors.

Clinical and economic impact of medication administration errors among neonates in neonatal intensive care units

Despite efforts in improving medication safety, medication administration errors are still common, resulting in significant clinical and economic impact. Studies conducted using a valid and reliable tool to assess clinical impact are lacking, and to the best of our knowledge, studies evaluating the economic impact of medication administration errors among neonates are not yet available. Therefore, this study aimed to determine the potential clinical and economic impact of medication administration errors in neonatal intensive care units and identify the factors associated with these errors. A national level, multi centre, prospective direct observational study was conducted in the neonatal intensive care units of five Malaysian public hospitals. The nurses preparing and administering the medications were directly observed. After the data were collected, two clinical pharmacists conducted independent assessments to identify errors. An expert panel of healthcare professionals assessed each medication administration error for its potential clinical and economic outcome. A validated visual analogue scale was used to ascertain the potential clinical outcome. The mean severity index for each error was subsequently calculated. The potential economic impact of each error was determined by averaging each expert's input. Multinomial logistic regression and multiple linear regression were used to identify factors associated with the severity and cost of the errors, respectively. A total of 1,018 out of 1,288 (79.0%) errors were found to be potentially moderate in severity, while only 30 (2.3%) were found to be potentially severe. The potential economic impact was estimated at USD 27,452.10. Factors significantly associated with severe medication administration errors were the medications administered intravenously, the presence of high-alert medications, unavailability of a protocol, and younger neonates. Moreover, factors significantly associated with moderately severe errors were intravenous medication administration, younger neonates, and an increased number of medications administered. In the multiple linear regression analysis, the independent variables found to be significantly associated with cost were the intravenous route of administration and the use of high-alert medications. In conclusion, medication administration errors were judged to be mainly moderate in severity costing USD 14.04 (2.22-22.53) per error. This study revealed important insights and highlights the need to implement effective error reducing strategies to improve patient safety among neonates in the neonatal intensive care unit.

An Interruption Management Education Bundle: Feasibility Testing With Nursing Students

BACKGROUND

Interruptions and distractions are pervasive in health care settings, increase risks for errors, and decrease task efficiency. Researchers recommend the use of strategies to mitigate their negative effects.

PURPOSE

The purpose was to assess the feasibility and acceptability of (1) an education bundle that included an interruption management strategy and (2) simulated scenarios with embedded interruptions and distractions.

METHODS

Nineteen undergraduate nursing students participated in this repeated-measures, multimethods feasibility study. Data on interruption management behaviors were collected across 3 timepoints via direct observation of individual-simulated medication administration. Participants' perceptions of the education bundle were explored via semistructured interviews.

RESULTS

Participants described the simulated scenarios as realistic and interruption management strategy as easy to use and remember. Participants voiced increased confidence in handling interruptions after learning the strategy. The strategy averaged 4 seconds to apply.

CONCLUSIONS

Findings support the feasibility and acceptability of the bundle and need for studies to investigate the impact of the strategy on errors and task durations.

Empowering Nursing Students to Prevent Medication Error-Related Harms: A Step Toward Improving Patient Safety

Aim: Existing gaps in nursing curriculum particularly related to medication management such as administration and monitoring increase the propensity of nurses to commit medication errors during clinical practice. The present training program was conducted with an aim to sensitize and educate undergraduate nursing students on medication errors' related aspects. Methods: The participants were students pursuing bachelors nursing degree course (second and third year). The training "Medication errors: Role of Nurse practitioners" comprised of blended teaching methods such as theme lectures, hands on training exercises, small group case‑based learning, role plays, and nursing officer's practical experiences. The participants' knowledge and perception about medication errors were assessed at baseline (pre-intervention phase) and 1 week after program (post-intervention phase) with the help of a structured self-administered questionnaire in English language. Results: A total of 110 nursing students participated in the program. Post program there was a consistent increase in the number of correct responses to all knowledge-based questions with a significant improvement in knowledge scores from baseline [Baseline: (mean ± SD) 12.62 ± 2.33; Post-training: 18.52 ± 2.22; P < .001]. There was a positive change in the perception about medication errors among students. The participants rated the overall quality of program as excellent [66 (60%)] or very good [40 (36.4%)]. More than 90% agreed on its applicability in their future practice. Conclusions: The training was quite successful in educating nursing students on medication errors. There is a constant need to educate nurses and other healthcare providers including doctors and pharmacists on medication safety related aspects with an ultimate goal to improve patient safety.

Factors Influencing Medication Administration Errors as Perceived by Nurses in Pediatric Units in a Jordanian Tertiary Hospital: A Qualitative Descriptive Study

BACKGROUND

The World Health Organization declared that medication errors are the third largest global patient safety challenge. The medication administration stage is a common and susceptible stage for medical errors to occur.

OBJECTIVE

To explore the factors contributing to medication administration errors specifically in pediatric care units as perceived by nurses in a Jordanian hospital.

METHODS

A qualitative descriptive study was conducted involving face-to-face audio-recorded interviews with 9 nurses in a tertiary hospital located in the north of Jordan. A convenience sampling technique was used to select the participants of our study. Data were collected between October 2022 and November 2022. The data were analyzed using inductive thematic analysis.

RESULTS

Four themes emerged affecting medication administration errors in pediatric care units. These were environmental, staff, parents and patient, and medication-related factors.

CONCLUSION

The findings of this study raise awareness of the most frequent sources of medication errors in a Jordanian hospital. Holding training and supervision to raise awareness among nurses and the availability of equipment and supplies could improve medication safety practices.

A grounded theory of the implementation of medical orders by clinical nurses

OBJECTIVE

To explore the process of implementing medical orders by clinical nurses, and identify specific areas of concern in the implementation process, and uncover strategies to address these concerns.

BACKGROUND

The implementation of medical orders is a crucial responsibility for clinical nurses, as they bear legal accountability for the precise implementation of directives issued by medical practitioners. The accurate implementation of these orders not only shapes the quality and safety of healthcare services but also presents numerous challenges that demand careful consideration.

METHOD

This study employed a qualitative design using a grounded theory approach to construct a comprehensive theoretical framework grounded in the insights and experiences of nurses operating within the hospital settings of Iran. The study encompassed 20 participants, comprising 16 clinical nurses, two nurse managers, and two specialist doctors working in hospital settings. The selection process involved purposeful and theoretical sampling methods to ensure diverse perspectives. Data collection unfolded through in-depth, individual, semi-structured interviews, persisting until data saturation was achieved. The analytical framework proposed by Corbin and Strauss (2015) guided the process, leading to the development of a coherent theory encapsulating the essence of the study phenomenon.

FINDINGS

The primary finding of the study underscores the significance of 'legal threat and job prestige' highlighting diverse repercussions in case of errors in the implementation of medical orders. At the core of the investigation, the central variable and the theory of the study was the 'selective and tasteful implementation of orders to avoid legal and organizational accountability.' This indicated a set of strategies employed by the nurses in the implementation of medical orders, encapsulated through three fundamental concepts: 'accuracy in controlling medical orders,' 'untruth documentation,' and 'concealment of events. The formidable influence of legal threats and job prestige was further compounded by factors such as heavy workloads, the doctor's non-compliance with legal instructions for giving verbal orders, the addition of orders by the doctor without informing nurses, and pressure by nursing managers to complete documentation. The resultant psychological distress experienced by nurses not only jeopardized patient safety but also underscored the intricate interplay between legal implications and professional standing within the healthcare framework.

CONCLUSION

Alleviating staff shortages, enhancing the professional rapport between doctors and nurses, offering legal support to nursing staff, implementing measures such as recording departmental phone conversations to deter the non-acceptance of verbal orders, fostering an organizational culture that embraces nurse fallibility and encourages improvement, and upgrading equipment can ameliorate nurses' apprehensions and contribute to the safe implementation of medical orders.

The insomnia, fatigue, and psychological well-being of hospital nurses 18 months after the COVID-19 pandemic began: A cross-sectional study

BACKGROUND

Research has shown sleep problems, elevated fatigue, and high cases of burnout, as well as signs of post-traumatic stress and psychological distress among nurses during the COVID-19 pandemic. Many US hospitals attempted to minimise its impact on staff by providing basic resources, mental health services, and wellness programs. Therefore, it is critical to re-evaluate these well-being indices and guide future administrative efforts.

PURPOSE

To determine the long-term impact of the COVID-19 pandemic after 18 months on hospital nurses' insomnia, fatigue, burnout, post-traumatic stress, and psychological distress.

DESIGN

Cross-sectional.

METHODS

Data were collected online mainly through state board and nursing association listservs between July-September 2021 (N = 2488). The survey had psychometrically tested instruments (Insomnia Severity Index, Occupational Fatigue Exhaustion Recovery Scale, Maslach Burnout Inventory, Short Post-Traumatic Stress Disorder, and Patient Health Questionnaire-4) and sections on demographics, health, and work. The STrengthening the Reporting of Observational studies in Epidemiology checklist was followed for reporting.

RESULTS

Nurses had subthreshold insomnia, moderate-to-high chronic fatigue, high acute fatigue, and low-to-moderate intershift recovery. Regarding burnout, they experienced increased emotional exhaustion and personal accomplishment, and some depersonalisation. Nurses had mild psychological distress but scored high on post-traumatic stress. Nurses who frequently cared for patients with COVID-19 in the past months scored significantly worse in all measures than their co-workers. Factors such as nursing experience, shift length, and frequency of rest breaks were significantly related to all well-being indices.

CONCLUSION

Nurses' experiences were similar to findings from the early pandemic but with minor improvements in psychological distress. Nurses who frequently provided COVID-19 patient care, worked ≥12 h per shift, and skipped rest breaks scored worse on almost all well-being indices.

RELEVANCE TO CLINICAL PRACTICE

Administration can help nurses' recovery by providing psychological support, mental health services, and treatment options for insomnia, as well as re-structure current work schedules and ensure that rest breaks are taken.

Registered Nurses' Knowledge of Intravenous Fluid Therapy at a Teaching Hospital in Namibia: A Cross-Sectional Survey

Introduction

Insufficient knowledge of intravenous fluid therapy is a significant challenge contributing to morbidity and mortality in hospitalized patients. Nurses play a critical role in evaluating patients' fluid and electrolyte balance as well as in restoring fluid levels. Various studies have indicated a deficiency in nurses' knowledge of intravenous therapy, yet this remains understudied in many settings, including Namibia.

Objectives

To assess nurses' knowledge of intravenous fluid therapy and to describe the variables associated with knowledge of intravenous fluid therapy at a teaching hospital in Namibia.

Methods

A cross-sectional online survey involving 164 nurses who were recruited using total population sampling. Data were collected between September and November 2021, using a self-administered 14-item validated tool (α = 0.8). Data analysis was conducted using SPSSv28.0 software.

Results

The majority of nurses (84%) in this study exhibited an insufficient level of knowledge regarding intravenous therapy, with only a minority (16%) demonstrating a moderately adequate understanding of intravenous fluid therapy. A significant positive correlation was found between educational qualification and knowledge of intravenous therapy (r = 0.21; p = .01).

Conclusion

The study's results indicate a worrying trajectory in nurses' knowledge of intravenous therapy. These findings underscore the need for hospitals to establish comprehensive training programs for nurses to guarantee the provision of secure and efficient intravenous therapy. Additional research is needed to investigate how educational qualifications impact patient outcomes related to intravenous therapy.

Fatigue in nurses and medication administration errors: A scoping review

BACKGROUND

Medication administration errors (MAEs) cause preventable patient harm and cost billions of dollars from already-strained healthcare budgets. An emerging factor contributing to these errors is nurse fatigue. Given medication administration is the most frequent clinical task nurses undertake; it is vital to understand how fatigue impacts MAEs.

OBJECTIVE

Examine the evidence on the effect of fatigue on MAEs and near misses by registered nurses working in hospital settings.

METHOD

Arksey and O'Malley's scoping review framework was used to guide this review and PAGER framework for data extraction and analysis. The PRISMA checklist was completed. Four electronic databases were searched: CINAHL, PubMed, Scopus and PsycINFO. Eligibility criteria included primary peer review papers published in English Language with no date/time limiters applied. The search was completed in August 2021 and focussed on articles that included: (a) registered nurses in hospital settings, (b) MAEs, (c) measures of sleep, hours of work, or fatigue.

RESULTS

Thirty-eight studies were included in the review. 82% of the studies identified fatigue to be a contributing factor in MAEs and near misses (NMs). Fatigue is associated with reduced cognitive performance and lack of attention and vigilance. It is associated with poor nursing performance and decreased patient safety. Components of shift work, such as disruption to the circadian rhythm and overtime work, were identified as contributing factors. However, there was marked heterogeneity in strategies for measuring fatigue within the included studies.

RELEVANCE TO CLINICAL PRACTICE

Fatigue is a multidimensional concept that has the capacity to impact nurses' performance when engaged in medication administration. Nurses are susceptible to fatigue due to work characteristics such as nightwork, overtime and the requirement to perform cognitively demanding tasks. The mixed results found within this review indicate that larger scale studies are needed with particular emphasis on the impact of overtime work. Policy around safe working hours need to be re-evaluated and fatigue management systems put in place to ensure delivery of safe and quality patient care.

Prevalence and determinants of medication administration errors in clinical wards: A two-centre prospective observational study

AIMS AND OBJECTIVES

To identify the prevalence and determinants of medication administration errors (MAEs).

BACKGROUND

Insight into determinants of MAEs is necessary to identify interventions to prevent MAEs.

DESIGN

A prospective observational study in two Dutch hospitals, a university and teaching hospital.

METHODS

Data were collected by observation. The primary outcome was the proportion of administrations with one or more MAEs. Secondary outcomes were the type, severity and determinants of MAEs. Multivariable mixed-effects logistic regression analyses were used for determinant analysis. Reporting adheres to the STROBE guideline.

RESULTS

MAEs occurred in 352 of 2576 medication administrations (13.7%). Of all MAEs (n = 380), the most prevalent types were omission (n = 87) and wrong medication handling (n = 75). Forty-five MAEs (11.8%) were potentially harmful. The pharmaceutical forms oral liquid (odds ratio [OR] 3.22, 95% confidence interval [CI] 1.43-7.25), infusion (OR 1.73, CI 1.02-2.94), injection (OR 3.52, CI 2.00-6.21), ointment (OR 10.78, CI 2.10-55.26), suppository/enema (OR 6.39, CI 1.13-36.03) and miscellaneous (OR 6.17, CI 1.90-20.04) were more prone to MAEs compared to oral solid. MAEs were more likely to occur when medication was administered between 10 a.m.-2 p.m. (OR 1.91, CI 1.06-3.46) and 6 p.m.-7 a.m. (OR 1.88, CI 1.00-3.52) compared to 7 a.m.-10 a.m. and when administered by staff with higher professional education compared to staff with secondary vocational education (OR 1.68, CI 1.03-2.74). MAEs were less likely to occur in the teaching hospital (OR 0.17, CI 0.08-0.33). Day of the week, patient-to-nurse ratio, interruptions and other nurse characteristics (degree, experience, employment type) were not associated with MAEs.

CONCLUSIONS

This study identified a high MAE prevalence. Identified determinants suggest that focusing interventions on complex pharmaceutical forms and error-prone administration times may contribute to MAE reduction.

RELEVANCE TO CLINICAL PRACTICE

The findings of this study can be used to develop targeted interventions to improve patient safety.

An umbrella review of systematic reviews on contributory factors to medication errors in health-care settings

INTRODUCTION

Medication errors are common events that compromise patient safety and are prevalent in all health-care settings. This umbrella review aims to systematically evaluate the evidence on contributory factors to medication errors in health-care settings in terms of the nature of these factors, methodologies and theories used to identify and classify them, and the terminologies and definitions used to describe them.

AREAS COVERED

Medline, Cumulative Index to Nursing and Allied Health Literature, Embase, and Google Scholar were searched from inception to March 2022. The data extraction form was derived from the Joanna Briggs Institute (JBI) Reviewers' Manual, and critical appraisal was conducted using the JBI quality assessment tool. A narrative approach to data synthesis was adopted.

EXPERT OPINION

Twenty-seven systematic reviews were included, most of which focused on a specific health-care setting or clinical area. Decision-making mistakes such as non-consideration of patient risk factors most commonly led to error, followed by organizational and environmental factors (e.g. understaffing and distractions). Only 10 studies had a pre-specified methodology to classify contributory factors, among which the use of theory, specifically Reason's theory was commonly used. None of the reviews evaluated the effectiveness of interventions in preventing errors. The collated contributory factors identified in this umbrella review can inform holistic theory-based intervention development.

Experience of Nurses with Intravenous Fluid Monitoring for Patient Safety: A Qualitative Descriptive Study

Purpose

Medication administration is a complex process and constitutes a substantial component of nursing practice that is closely linked to patient safety. Although intravenous fluid administration is one of the most frequently performed nursing tasks, nurses’ experiences with intravenous rate control have not been adequately studied. This study aimed to explore nurses’ experiences with infusion nursing practice to identify insights that could be used in interventions to promote safe medication administration.

Patients and methods

This qualitative descriptive study used focus group interviews of 20 registered nurses who frequently administered medications in tertiary hospitals in South Korea. Data were collected through five semi-structured focus group interviews, with four nurses participating in each interview. We conducted inductive and deductive content analysis based on the 11 key topics of patient safety identified by the World Health Organization. Reporting followed the consolidated criteria for reporting qualitative research (COREQ) checklist.

Results

Participants administered infusions in emergency rooms, general wards, and intensive care units, including patients ranging from children to older adults. Two central themes were revealed: human factors and systems. Human factors consisted of two sub-themes including individuals and team players, while systems encompassed three sub-themes including institutional policy, culture, and equipment.

Conclusion

This study found that nurses experienced high levels of stress when administering infusions in the correct dose and rate for patient safety. Administering and monitoring infusions were complicated because nursing processes interplay with human and system factors. Future research is needed to develop nursing interventions that include human and system factors to promote patient safety by reducing infusion-related errors.

Assessing Nursing Students' Self-Perceptions about Safe Medication Management: Design and Validation of a Tool, the NURSPeM

Objective: The objective was to design and validate a tool for assessing nursing students’ self-perceptions about safe medication management. Methods: A descriptive instrumental study was conducted involving construct definition, development of the tool, analysis of the content validity, and psychometric evaluation. Consensus regarding the content was obtained through a two-round Delphi process, and the resulting tool (the NURSPeM) was administered to nursing students to examine its internal consistency, temporal stability, and construct validity, the latter through exploratory factor analysis. Results: Thirteen experts participated in the Delphi process, which yielded a tool comprising two questionnaires: (1) Self-perceptions about safe medication management (27 items) and (2) the frequency and learning of drug-dose calculation (13 items). The tool’s psychometric properties were then examined based on responses from 559 nursing students. This analysis led to the elimination of three items from questionnaire 1, leaving a total of 24 items distributed across seven dimensions. All 13 items in questionnaire 2 were retained. Both questionnaires showed good internal consistency (Cronbach’s alpha = 0.894 and 0.893, respectively) and temporal stability (ICC = 0.894 and 0.846, respectively). Conclusions: The NURSPeM is a valid and reliable tool for assessing nursing students’ self-perceptions about safe medication management. It may be used to identify areas in which their training needs to be enhanced, and to evaluate the subsequent impact of new teaching initiatives.

Untenable Expectations: Nurses’ Work in the Context of Medication Administration, Error, and the Organization

We explored nurses’ work in the context of medication administration, errors, and the organization. Secondary analysis of ethnographic data included 92 hours of non-participant observation, and 37 unstructured interviews with nurses, administrators, and pharmacists. Think-aloud observations and analysis of institutional documents supplemented these data. Findings revealed the nature of nurses’ work was characterized by chasing a standard of care, prioritizing practice, and renegotiating routines. The rich description identified characteristics of nurses’ work as cyclical, chaotic and complex shattering studies that explained nurses’ work as linear. A new theoretical model was developed, illustrating the inseparability of nurses’ work from contextual contingencies and enhancing our understanding of the cascading components of work that result in days that spin out of the nurses’ control. These results deepen our understanding why present efforts targeting the reduction of medication errors may be ineffective and places administration accountable for the context in which medication errors occur.

Exploring Nurses' Perceptions of Medication Error Risk Factors: Findings From a Sequential Qualitative Study

A focus group study was conducted to explore nurses' perceptions of medication administration error associated factors in two medical wards of a tertiary hospital. Nurses were invited to participate in focus group discussions. Thematic analysis was employed and identified four themes: professional practice environment related factors, person-related factors, drug-related factors, and processes and procedures. Staffing, interruptions, system failures, insufficient leadership, and patient acuity were perceived as risk factors for medication errors. The findings of this study complement the findings of an observational study which investigated medication administration errors in the same setting. Although some findings were similar, important risk factors were identified only through focus group discussions with nurses. Nurses' perceptions of factors influencing medication administration errors provide important considerations in addressing factors that contribute to errors and for improving patient safety.
