Factors contributing to incidents in medicine administration. Part 1

Part one of this two-part article explores the factors contributing to errors during the administration of medicines through a detailed literature review. Medication incidents cause serious harm to patients. In a typical NHS hospital approximately 7000 medication doses are administered daily (Audit Commission, 2002a). The costs of errors to patients, practitioners and the NHS are significant. While some errors can be prevented, it is unlikely that they will ever be eliminated as they arise from human nature (Kohn et al, 2000). There is a lack of strong evidence in the literature about what nurses feel the factors contributing to medication errors are. The majority of studies were carried out in the USA and tended to be carried out by non-nurses with the exception of those by Gladstone (1995), Hand and Barber (2000) and King (2004). Gibson (2001) felt that nurses' experiences and knowledge appear to be undervalued.     

Factors Affecting Incident Reporting by Registered Nurses: The Relationship of Perceptions of the Environment for Reporting Errors, Knowledge of the Nursing Practice Act, and Demographics on Intent to Report Errors

Patient safety has assumed an international focus. In the past, the focus on detecting and preventing errors was up to the individual clinician, often the registered nurse. With impetus from the Institute of Medicine and other national agencies, a shift to emphasis on systems and processes and near miss and error reporting has occurred. Information from caregiver reporting has taken on new importance. This study was conducted to explore nurses' willingness to report errors of varying degrees of severity and the factors that impacted that intent. Registered nurses were selected randomly from the Texas Board of Nurse Examiners' roster and surveyed regarding perceptions of the environment for reporting, perceptions of reasons for not reporting, knowledge of the nursing practice act, and demographic variables. A majority of nurses were willing to report all levels of errors. Primary position, reasons for not reporting, and years since initial licensure were predictors of intent to report incidents with no injury and those with minimal injury. All but four nurses (99%) indicated that they would report incidents resulting in moderate to severe injury or death.     

Antecedents of Severe and Nonsevere Medication Errors

Purpose: To investigate if differences in antecedents of severe and nonsevere medication errors exist.
Design: A longitudinal study of 6 months of data from 279 nursing units in 146 randomly selected hospitals in the United States (US).
Methods: Antecedents of severe and nonsevere medication errors included work environment factors (work dynamics and RN hours), team factors (communication with physicians and nurses' expertise), person factors (nurses' education and experience), patient factors (age, health status, and previous hospitalization), and medication-related support services. Generalized estimating equations with a negative binomial distribution were used with nursing units as the unit of analysis.
Findings: None of the antecedents allowed predicting both types of medication errors. Nurses' expertise had a negative and medication-related support services had a positive association with nonsevere medication errors. Nurses' educational level had a significant nonlinear relationship with severe medication errors only: As the percentage of unit BSN-prepared nurses increased, severe medication errors decreased until the percentage of BSN-prepared nurses reached 54%. In contrast, RN experience had a statistically significant relationship with nonsevere medication errors only and nursing units with more experienced nurses reported more nonsevere medication errors.
Conclusions: Severe and nonsevere medication errors might have different antecedents.
Clinical Relevance: Error prevention and management strategies should be targeted to specific types of medication errors for best results.     

Nurses’ views on reporting medication incidents

Walker SB, Lowe MJ. International Journal of Nursing Practice 1998; 4: 97–102 Nurses’ views on reporting medication incidents The purpose of this project was to identify nurses’ beliefs about medication incident reporting. A new medication incident form was developed and trialled in six clinical units. Forty-three nurses from these areas were recruited to participate in the project, with a 20-point self-reporting questionnaire and focus group discussions being used to collect the data. Theme analysis of the data was undertaken with the results of the project indicating nurses report medication incidents that are life threatening to patients, but do not want identifying information collected about themselves. This situation represents nurses’ fear of reprimand from those in authority and may also indicate an unwillingness to accept responsibility for errors in which they may be merely the final player in a complex series of events. The results of the project also highlight problems associated with self-reported medication incident monitoring and challenge its effectiveness in gathering data required by managers and staff development educators.

Understanding the cognitive work of nursing in the acute care environment

OBJECTIVE: To combine human factors engineering techniques with qualitative observation of nurses in practice to analyze the nature of nurses' cognitive work and how environmental factors create disruptions that pose risks for medical errors. BACKGROUND: Few researchers have examined the nature of nurses' cognitive work while in practice with patients. Researchers have described the broad range of thinking processes required in the acute care work setting, but have failed to examine how such processes are conducted and influenced by the complex care environment. A combined research methodology enables researchers to better understand how the nursing process becomes disrupted and the potential influence of this disruption on the safe and effective care of patients. METHODS: An ethnographic study, using mixed-methodological approaches, involved 7 staff registered nurses. The quantitative and qualitative data collection included field observation and summarative interviews. FINDINGS: A high number of cognitive shifts and interruptions, and a nurse's cumulative cognitive load, create the potential for disrupting a nurse's attention focus during care of patients. A majority of interruptions occurred as nurses performed interventions, particularly medication preparation. CONCLUSION: New attention must be given to how care systems and work processes complement or interfere with nurses' cognitive work.     

Factors associated with reporting of medication errors by Israeli nurses

This study investigated medication error reporting among Israeli nurses, the relationship between nurses' personal views about error reporting, and the impact of the safety culture of the ward and hospital on this reporting. Nurses (n = 201) completed a questionnaire related to different aspects of error reporting (frequency, organizational norms of dealing with errors, and personal views on reporting). The higher the error frequency, the more errors went unreported. If the ward nurse manager corrected errors on the ward, error self-reporting decreased significantly. Ward nurse managers have to provide good role models.     

Let's do no harm: Medication errors in nursing: Part 1

In the current climate of global economic chaos and increasing healthcare litigation, it is perhaps simultaneously unsurprising and yet perplexing that patients continue to fall foul of healthcare systems worldwide. Major incidents in patient care such as serious misdiagnoses, medication errors, the proliferation of superbugs and malpractice persist leading to injury or death of patients, emotional trauma to their families and, understandably, a reduction in the public's confidence in the healthcare system not to mention the financial consequences. Many, if not most or indeed all, of these incidents are preventable and should not happen. Yet the systems in place within healthcare permit their occurrence, with worrying regularity, it would appear. The area that this paper will focus on specifically is that of medication errors. The worrying trends with regard to medication errors will be presented. Potential contributing factors will be examined. The specific aim of this paper is to illuminate the extent and severity of the problem of medication errors in practice and to explore elements within the practice setting that can compound the problem. The multi-faceted nature of the problem will also be considered.     

Geropharmacology: a primer for advanced practice acute care and critical care nurses, part I

Advanced practice nurses' challenge in managing older adults' medication regimens from an evidence base is difficult because older adults are vulnerable to medication errors and adverse drug reactions related to a number of factors. Predicting patients' responses to drugs is compounded during critical illness, adding to the heterogeneity and unpredictability of drug effects that are prevalent premorbidly. In the first part of this 2-part continuing education series, sources of medication errors and older adults' vulnerability are discussed, including normal changes of aging affecting pharmacokinetics and pharmacodynamics, polypharmacy, self-medicating, patient-family noncompliance, and inappropriately prescribed medications. In the second part, drug classes and drugs posing particular problems for older adults and cautions for acute care and critical care nurses who manage the medications of older adults are highlighted.     

Nurses' evaluations of a novel design for an electronic medication administration record

An electronic medication administration record is at the intersection of several disciplines: medicine, nursing, pharmacy, and allied health; however, it is the centerpiece of nurses' work for medication administration in acute care settings. Despite the crucial nature of the electronic medication administration record, human-computer interaction and health literature are silent about design recommendations and evaluations for such records. This study determined critical on-line medication management tasks for acute care nurses through videotaped, semistructured interviews with nurses and then observations of nurses during medication administration tasks. Subsequently, a novel electronic medication administration record prototype was developed and evaluated. The usability evaluation of this new record was positive based upon scores from the Questionnaire for User Interaction Satisfaction and comments about the display. Mean scores for this questionnaire averaged 7.2 to 7.9 (on a scale of 1-9) or from 80.2% to 87.8%. Accuracy scores were low for tasks requiring nurses to examine data outside the immediate field of view. Specific design recommendations are made to alleviate accuracy errors for specific tasks in acute care settings.     

Nurses' perceptions of causes of medication errors and barriers to reporting

This study describes nurses' perceptions about medication errors and the effects of physician order entry and barcode medication administration on medication errors. A convenience sample of 61 medical-surgical nurses was surveyed. All nurses surveyed perceived that information technology decreases medication errors. However, medication errors continue to occur despite the availability of sophisticated information technology systems.     

Medication errors in the emergency department: a systems approach to minimizing risk

Adverse drug events caused by medication errors represent a common cause of patient injury in the practice of medicine. Many medication errors are preventable and hence particularly tragic when they occur, often with serious consequences. The enormous increase in the number of available drugs on the market makes it all but impossible for physicians, nurses, and pharmacists to possess the knowledge base necessary for fail-safe medication practice. Indeed, the greatest single systemic factor associated with medication errors is a deficiency in the knowledge requisite to the safe use of drugs. It is vital that physicians, nurses, and pharmacists have at their immediate disposal up-to-date drug references. Patients presenting for care in EDs are usually unfamiliar to their EPs and nurses, and the unique patient factors affecting medication response and toxicity are obscured. An appropriate history, physical examination, and diagnostic workup will assist EPs, nurses, and pharmacists in selecting the safest and most optimum therapeutic regimen for each patient. EDs deliver care "24/7" and are open when valuable information resources, such as hospital pharmacists and previously treating physicians, may not be available for consultation. A systems approach to the complex problem of medication errors will help emergency clinicians eliminate preventable adverse drug events and achieve a goal of a zero-defects system, in which medication errors are a thing of the past. New developments in information technology and the advent of electronic medical records with computerized physician order entry, ward-based clinical pharmacists, and standardized bar codes promise substantial reductions in the incidence of medication errors and adverse drug events. ED patients expect and deserve nothing less than the safest possible emergency medicine service.     

Nurses' views on ethical codes: a focus group study

AIM: This paper reports a study exploring nurses' views on the 'potential' content and functions of an ethical code for nurses in Belgium. The term 'potential' is used, because Belgian nurses do not have experience with an ethical code. BACKGROUND: Ethical codes have been developed to guide nurses' practice and to improve their professional status. Little empirical research, however, has been undertaken to determine nurses' views on the content and functions of these codes. The available quantitative studies merely give some information on nurses' (lack of) knowledge and use of their ethical code. No nursing ethical code currently exists in Belgium. Qualitative research exploring nurses' views, therefore, was needed in order to find out which functions an ethical code could fulfil and what the code's content could be. METHOD: Eight focus groups were conducted with 50 nurses in different healthcare settings in Belgium. Data were generated during 2003. FINDINGS: According to participants, an ethical code could fulfil several functions, including supporting their professional nursing identity (external function) and giving guidelines for nursing practice (internal function). In addition, some aspects of content were mentioned, including nurses' responsibilities in a relational context: particular attention should be paid to the personality of the nurse and to the specificity of nursing as a relational activity. Most agreement was reached on the 'ethical' function of the code, namely guiding nurses' professional moral practice. Regarding disciplinary use and the need for legalization of the ethical code, on the contrary, opinions were divergent. CONCLUSIONS: It is of utmost importance to take into account nurses' views when developing an ethical code for their profession. This study gave a first picture of the views of nurses themselves. These initial findings should be completed with nurses' views on the formulation, dissemination and promotion of the ethical code. Such evidence-based development of an ethical code will probably give more guarantees that the code will meet nurses' expectations and will function optimally.
