Nurses' perceptions of medication errors.
This study reports nurses' perceptions of medication errors and of their appropriate reporting. Thirty-three percent of the participants believed the main cause of medication errors was nurses' tiredness or exhaustion, while 30% of participants indicated that the main cause was the poor legibility or illegibility of physcians' writing on the doctor's order form. Some medication errors were not reported because nurses were afraid of reprisals (63%).

A comparison of medication errors between two storage sites.
This prospective single-blinded study aimed to compare the types of medication errors and medication error rates of two medication delivery systems. The setting was a 30 bed surgical ward that was divided into two identical areas. In one area medications were stored and issued in a ward bay workstation immediately outside the patients' rooms. The alternate area used a medication trolley at the patients' bedside. Three hundred and forty opportunities for errors were observed using five nurse educators. Twenty administration errors (5.8% error rate) and two dispensing errors (0.6% error rate) were detected. A statistically significant difference was found between the two systems, where four errors occurred from the medication trolley (2.6% error rate), and fifteen errors occurred from the ward bay (9.2% error rate). These results suggest that medications were less likely to be omitted and more likely to be given on time when they were issued at the patient's bedside using the medication trolley.

Development of an expert system for classification of medical errors.
The 1999 report published by the Institute of Medicine (IOM) indicated that between 44,000 and 98,000 unnecessary deaths per year occurred in hospitals alone, as a result of errors committed by medical professionals in the United States. There has been considerable speculation that these figures are either overestimated or underestimated. For example, the possibility that they focus on isolated injuries rather than error, or the majority of surveyed respondents did not know what constitutes a (medical) error. These disagreements have led experts to challenge the estimates of patient harm attributable to error, as well as the methodologies used to enumerate them. Of particular concern is the process used in the identification, classification and prevention of medical errors. There have been numerous attempts to develop classifications of medical errors, and currently an abundance of taxonomies exist to describe their mechanism.In previous research, (Kopec, Kabir, Reinharth, Rothschild & Castiglione, 2003) a new taxonomy of Medical Errors was designed by expanding the IOM classification. This model and its extension can be used as a blueprint for future design, development and implementation of an expert system for classification of medical errors. Effective classification can facilitate pattern recognition, and pattern recognition will help in understanding the nature, background and abatement of medical errors. Such a system's goal will be to perform convincingly as an advisory consultant, exhibiting expertise on a par with and beyond human experts in specified domains. Despite substantial disagreement on the validity of the published figures for fatalities in hospitals in the IOM report, what is of importance is that the number of deaths caused by such errors is nonetheless alarming. The identification and classification of errors in medical care delivery is a very complex process, and this process can be facilitated and simplified by the implementation of an effective classification system.

Bioethics for clinicians: 23. Disclosure of medical error.
Adverse events and medical errors are not uncommon. In this article we review the literature on such events and discuss the ethical, legal and practical aspects of whether and how they should be disclosed to patients. Ethics, professional policy and the law, as well as the relevant empirical literature, suggest that timely and candid disclosure should be standard practice. Candour about error may lessen, rather than increase, the medicolegal liability of the health care professionals and may help to alleviate the patient's concerns. Guidelines for disclosure to patients, and their families if necessary, are proposed.

The SHEL model: a useful tool for analyzing and teaching the contribution of Human Factors to medical error.
Recent reports on the problem of medical error pointed to a discipline that has been until recently, largely disregarded by the medical profession. The interdisciplinary science of Human Factors, the reports argue, provides a pragmatic framework for analyzing and assessing risk and reducing error in health care. The argument for applying Human Factors analysis to health care is increasingly accepted, and the application of Human Factors systems models for understanding medical error in particular have proved to be especially illuminating. The authors present a conceptual model of Human Factors--the SHEL model (named after the initial letters of its components' names, Software, Hardware, Environment, and Liveware)--that has been used in investigations of error in aviation. The authors use this simple model to examine and elucidate the Human Factors issues in a specific real-life example of medical error. The SHEL model is particularly useful in examining Human Factors issues in microsystems in health care such as the emergency room or the operating theatre; it argues that mismatches at the interface between the components in these health care microsystems are often conducive to medical errors. The authors propose that the SHEL model may have some unexploited potential in analyzing error and in training medical professionals about the science of Human Factors and its application to medical error. Empirical studies are needed, however, to ascertain the optimal amount of training needed to make clinically significant reductions in the occurrence of medical error.

Medication errors associated with anticoagulant therapy in the hospital.
Anticoagulation in hospitalized patients is frequently associated with medication errors. To determine the extent and severity of this problem, we reviewed consecutively reported, anticoagulation-related medication errors over a 3-year period. We identified 130 medication errors. There were 1.67 medication errors for every 1,000 patients treated with anticoagulants. These were most often associated with unfractionated heparin (66.2%), followed by warfarin (21.5%), low-molecular-weight heparin (9.2%), argatroban (1.5%), and lepirudin (1.5%). There were no deaths attributed to any anticoagulant medication errors, but 6.2% of patients required medical intervention and 1.5% needed prolonged hospitalization. Medication errors frequently occur with anticoagulant therapy in hospitalized patients.

Medication errors in United States hospitals.
This study evaluated hospital demographics, staffing, pharmacy variables, health care outcomes measures (severity of illness-adjusted mortality rates, drug costs, total cost of care, and length of stay) and medication errors. A database was constructed from the 1992 American Hospital Association's Abridged Guide to the Health Care Field, the 1992 National Clinical Pharmacy Services database, and 1992 mortality data from the Health Care Financing Administration. Simple statistical tests and a severity of illness-adjusted multiple regression analysis were employed. The study population consisted of 1116 hospitals that reported information on medication errors and 913 hospitals that reported information on medication errors that adversely affected patient care outcomes. We evaluated factors associated with the 430,586 medication errors and 17,338 medication errors that adversely affected patient care outcomes. Medication errors occurred in 5.07% of the patients admitted each year to these hospitals. Each hospital experienced a medication error every 22.7 hours (every 19.73 admissions). Medication errors that adversely affected patient care outcomes occurred in 0.25% of all patients admitted to these hospitals/year. Each hospital experienced a medication error that adversely affected patient care outcomes every 19.23 days (or every 401 admissions). The following factors were associated with increased medication errors/occupied bed/year: lack of pharmacy teaching affiliation (slope = 0.8875, p=0.0416), centralized pharmacists (slope = 1.0942, p=0.0001), number of registered nurses/occupied bed (slope = 1.624, p=0.032), number of registered pharmacists/occupied bed (slope = 25.0573, p=0.0001), hospital mortality rate (slope = 2.8017, p=0.0192), and total cost of care/occupied bed/year (slope = 0.01432, p=0.0091). Factors associated with decreased medication errors were location in the Mid-Atlantic census region (slope = -1.5182, p=0.03), affiliation with a pharmacy teaching program (slope = -1.0252, p=0.0349), decentralized pharmacists (slope = -0.9843, p=0.0037), and number of medical residents/occupied bed (slope = -1.478, p=0.0014). There was a 45% decrease in medication errors (1.81-fold decrease) in hospitals that had decentralized pharmacists, compared with hospitals that had centralized pharmacists. In addition, there was a 94% decrease in medication errors that adversely affected patient care outcomes (16.88-fold decrease) in hospitals that had decentralized pharmacists compared with hospitals that had only centralized pharmacists. Based on previous field studies and our findings in 1116 hospitals, it appears that one of the most effective ways to prevent or reduce medication errors is to decentralize pharmacists to patient care areas. The results of this study should help hospitals reduce the number of medication errors that occur each year.

[Medical errors in hospitalized patients].
OBJECTIVE: To review the current literature and to discuss medical errors in hospitalized patients emphasizing its incidence, predisposing factors and prevention mechanism. Special attention is given to medication errors and adverse drug events in newborn infants and pediatric patients. SOURCES: Bibliographic review of the current literature through electronic search in Medline data-base, with selection of the most relevant articles. SUMMARY OF THE FINDINGS: Even though most medical errors are not reported, it is important to notice that its incidence is greater than previously assumed. In the USA, approximately one million of patients/year are victims of medical errors and adverse drug events. Today, deaths resulting from these episodes are the fourth cause of mortality in the USA. In neonatal and pediatric intensive care units, where the complexity and frequency of technical procedures are high, medical errors are frequent. Fifteen percent of all admissions to a neonatal intensive care unit is followed by medical errors. Most of these errors occur during night shifts and include incorrect administration of drugs (35%) and errors regarding the interpretation of medical prescription (26%). Environmental factors (noise, heat), psychological factors (anxiety, stress) and physiologic factors (fatigue, absence of sleep) contribute to the occurrence of errors. Recent study shows that after working 24 hours without sleeping, the performance of a health professional is similar to a legally drunk person (serum alcohol level > or =0.08%). CONCLUSIONS: Errors are part of human behavior. The prevention of errors should include a careful review of the organizational system. Medical errors should be seen as an opportunity to change or re-structure the system and to improve the quality of health care delivered and patient safety.

Patients' and physicians' attitudes regarding the disclosure of medical errors.
CONTEXT: Despite the best efforts of health care practitioners, medical errors are inevitable. Disclosure of errors to patients is desired by patients and recommended by ethicists and professional organizations, but little is known about how patients and physicians think medical errors should be discussed. OBJECTIVE: To determine patients' and physicians' attitudes about error disclosure. DESIGN, SETTING, AND PARTICIPANTS: Thirteen focus groups were organized, including 6 groups of adult patients, 4 groups of academic and community physicians, and 3 groups of both physicians and patients. A total of 52 patients and 46 physicians participated. MAIN OUTCOME MEASURES: Qualitative analysis of focus group transcripts to determine the attitudes of patients and physicians about medical error disclosure; whether physicians disclose the information patients desire; and patients' and physicians' emotional needs when an error occurs and whether these needs are met. RESULTS: Both patients and physicians had unmet needs following errors. Patients wanted disclosure of all harmful errors and sought information about what happened, why the error happened, how the error's consequences will be mitigated, and how recurrences will be prevented. Physicians agreed that harmful errors should be disclosed but "choose their words carefully" when telling patients about errors. Although physicians disclosed the adverse event, they often avoided stating that an error occurred, why the error happened, or how recurrences would be prevented. Patients also desired emotional support from physicians following errors, including an apology. However, physicians worried that an apology might create legal liability. Physicians were also upset when errors happen but were unsure where to seek emotional support. CONCLUSIONS: Physicians may not be providing the information or emotional support that patients seek following harmful medical errors. Physicians should strive to meet patients' desires for an apology and for information on the nature, cause, and prevention of errors. Institutions should also address the emotional needs of practitioners who are involved in medical errors.

Toward efficient medication error reduction: error-reducing information management systems.
Hospitals and other health-care providers today are being pressed more than ever to use technologies for reducing medical errors. Particularly, medication errors are likely to increase fast as Americans age. This paper intends to provide a starting point for understanding information technologies and database systems supporting such technologies as Computerized Physician Order Entry (CPOE), Automated Dispensing System (ADS), and Bar Coding System designed to reduce medication errors in hospitals. Although vendors provide the necessary communication software and applications, actions involving governments, technology vendors, pharmaceutical companies, and clinical researchers are needed to put to actual use the applications with a massive potential to significantly reduce medication-related errors.

Disclosure of medical errors: what factors influence how patients respond?
BACKGROUND: Disclosure of medical errors is encouraged, but research on how patients respond to specific practices is limited. OBJECTIVE: This study sought to determine whether full disclosure, an existing positive physician-patient relationship, an offer to waive associated costs, and the severity of the clinical outcome influenced patients' responses to medical errors. PARTICIPANTS: Four hundred and seven health plan members participated in a randomized experiment in which they viewed video depictions of medical error and disclosure. DESIGN: Subjects were randomly assigned to experimental condition. Conditions varied in type of medication error, level of disclosure, reference to a prior positive physician-patient relationship, an offer to waive costs, and clinical outcome. MEASURES: Self-reported likelihood of changing physicians and of seeking legal advice; satisfaction, trust, and emotional response. RESULTS: Nondisclosure increased the likelihood of changing physicians, and reduced satisfaction and trust in both error conditions. Nondisclosure increased the likelihood of seeking legal advice and was associated with a more negative emotional response in the missed allergy error condition, but did not have a statistically significant impact on seeking legal advice or emotional response in the monitoring error condition. Neither the existence of a positive relationship nor an offer to waive costs had a statistically significant impact. CONCLUSIONS: This study provides evidence that full disclosure is likely to have a positive effect or no effect on how patients respond to medical errors. The clinical outcome also influences patients' responses. The impact of an existing positive physician-patient relationship, or of waiving costs associated with the error remains uncertain.

Why the need to reduce medical errors is not obvious.
According to Leape & Berwick (2000) the need to reduce medical errors is 'obvious and the mandate is clear'. My article questions this assertion. I go beyond the unknown incidence of medical errors in a general medical population to suggest that the meaning of medical errors is itself equivocal. I contest the assumption that the 'wrongness' of medical errors is always problematic, arguing instead for a distinction between desirable errors and undesirable errors. This distinction takes into account the consequences of errors, and why they may occur. Reasons include the inappropriateness of two cultural contexts--evidence-based medicine and continuous quality improvement--within which patient safety standards can be constructed and hence, medical errors can be defined.

Physician and public opinions on quality of health care and the problem of medical errors.
BACKGROUND: The 1999 Institute of Medicine report on medical errors proposed major changes to the health care system and gained widespread media attention, yet there is limited information on physician or public opinion regarding recommendations from that report. METHODS: Mail survey of 1000 Colorado physicians (n = 594) and 1000 national physicians (n = 304), and telephone survey of 500 Colorado households to assess agreement with several proposals and conclusions from the 1999 Institute of Medicine report. RESULTS: Most physicians believed that reduction of medical errors should be a national priority (69.7% of Colorado physicians). However, physicians were much less likely than the public to believe that quality of care is a problem (29.1% vs 67.6%; P<.001) or that a national agency is needed to address the problem of medical errors (24.1% vs 59.8%; P<.001). Uniformly, physicians believed that fear of medical malpractice is a barrier to reporting of errors and that greater legal safeguards are necessary for a mandatory reporting system to be successful. Nearly all physicians (92.9%) believed that more training in how to handle medical errors is needed, and 60.1% agreed that it is difficult to differentiate errors due to negligence from unintended errors. CONCLUSIONS: There appears to be widespread concern among physicians regarding medical errors, but only a minority in this survey believed that the problem is as significant as the Institute of Medicine and the public believe it to be. Our results suggest that physicians see several barriers to successful error reduction including difficulty defining errors, the need for more training in handling errors, and fear of malpractice litigation. Addressing these barriers will be a necessary step to increasing physician support for many of the changes proposed by the Institute of Medicine.

An interdisciplinary method of classifying and monitoring medication errors.
A system is described for reporting medication errors according to practitioner and type and using these data as part of a departmental quality-assessment program. Types of errors committed in prescribing, in dispensing, and in administering drugs in a teaching hospital were listed. Prescribers' and pharmacists' reports of errors committed. Data on dispensing errors by 16 staff pharmacists were collected over a 12-month period in 1982-83, and data on prescribing by resident physicians were collected during three separate one-month periods. For each pharmacist, data on dispensing errors were compiled monthly. Pharmacists were counseled if they had a large number of errors in one category, a high total number of errors, or a substantial number of errors in a single category over several months. Likewise, physicians who committed more errors than their department's mean were counseled by the clinical chairman. After 12 months, each pharmacist's monthly error rate was compared with the departmental average. The number of dispensing errors reported during the study period (average 60.7 per month for the department) was lower than expected. Serious prescribing errors were minimal. In spite of probable underreporting of errors in this voluntary system, these methods of classifying medication errors by type and practitioner group and of recording error rates were useful tools for monitoring and improving performance of pharmacists and prescribers.

Classification of medical errors and preventable adverse events in primary care: a synthesis of the literature.
OBJECTIVE: To describe and classify process errors and preventable adverse events that occur from medical care in outpatient primary care settings. STUDY DESIGN: Systematic review and synthesis of the medical literature. DATA SOURCES: We searched MEDLINE and the Cochrane Library from 1965 through March 2001 with the MESH term medical errors, modified by adding family practice, primary health care, physicians/family, or ambulatory care and limited the search to English-language publications. Published bibliographies and Web sites from patient safety and primary care organizations were also reviewed for unpublished reports, presentations, and leads to other sites, journals, or investigators with relevant work. Additional papers were identified from the references of the papers reviewed and from seminal papers in the field. OUTCOMES MEASURED: Process errors and preventable adverse events. RESULTS: Four original research studies directly studied and described medical errors and adverse events in primary care, and 3 other studies peripherally addressed primary care medical errors. A variety of quantitative and qualitative methods were used in the studies. Extraction of results from the studies led to a classification of 3 main categories of preventable adverse events: diagnosis, treatment, and preventive services. Process errors were classified into 4 categories: clinician, communication, administration, and blunt end. CONCLUSIONS: Original research on medical errors in the primary care setting consists of a limited number of small studies that offer a rich description of medical errors and preventable adverse events primarily from the physician's viewpoint. We describe a classification derived from these studies that is based on the actual practice of primary care and provides a starting point for future epidemiologic and interventional research. Missing are studies that have patient, consumer, or other health care provider input.
Adverse Drug Reaction Reporting Systems↗
Medication errors analysis is an opportunity to improve practice.
The United States Pharmacopeia (USP) Medication Errors Reporting (MER) Program collected and cataloged 2,213 reports between October 1991 and November 1996. Medication errors occur in all health care facilities, involve health care practitioners from all disciplines, and involve drugs from all categories, including neuromuscular blocking agents (38 out of 2,213). This class of drugs is discussed as an example of the program, and we trust will serve the reader as an educational guide about medication errors that occur with drugs in any class. When used inappropriately, they represent a higher morbidity and mortality than many other drug classes analyzed. Reports indicate various causes for the errors, such as similar-appearing products, and include suggestions by practitioners to prevent recurrence of the error. The USP Advisory Panel on Medication Errors has developed recommendations for facilities that are intended to prevent errors with neuromuscular blocking agents (NMB). The USP Medication Errors Reporting Program is presented in cooperation with the Institute for Safe Medication Practices (ISMP).
