A systems approach to medication error reduction

Nurses' medication administration practices at two Singaporean acute care hospitals

This study examined registered nurses' overall compliance with accepted medication administration procedures, and explored the distractions they faced during medication administration at two acute care hospitals in Singapore. A total of 140 registered nurses, 70 from each hospital, participated in the study. At both hospitals, nurses were distracted by personnel, such as physicians, radiographers, patients not under their care, and telephone calls, during medication rounds. Deviations from accepted medication procedures were observed. At one hospital, the use of a vest during medication administration alone was not effective in avoiding distractions during medication administration. Environmental factors and distractions can impact on the safe administration of medications, because they not only impair nurses' level of concentration, but also add to their work pressure. Attention should be placed on eliminating distractions through the use of appropriate strategies. Strategies that could be considered include the conduct of education sessions with health professionals and patients about the importance of not interrupting nurses while they are administering medications, and changes in work design.

Strategies to reduce medication errors with reference to older adults

Background  In Australia, around 59% of the general population uses prescription medication with this number increasing to about 86% in those aged 65 and over and 83% of the population over 85 using two or more medications simultaneously. A recent report suggests that between 2% and 3% of all hospital admissions in Australia may be medication related with older Australians at higher risk because of higher levels of medicine intake and increased likelihood of being admitted to hospital. The most common medication errors encountered in hospitals in Australia are prescription/medication ordering errors, dispensing, administration and medication recording errors. Contributing factors to these errors have largely not been reported in the hospital environment. In the community, inappropriate drugs, prescribing errors, administration errors, and inappropriate dose errors are most common. Objectives  To present the best available evidence for strategies to prevent or reduce the incidence of medication errors associated with the prescribing, dispensing and administration of medicines in the older persons in the acute, subacute and residential care settings, with specific attention to persons aged 65 years and over. Search strategy  Bibliographic databases PubMed, Embase, Current contents, The Cochrane Library and others were searched from 1986 to present along with existing health technology websites. The reference lists of included studies and reviews were searched for any additional literature. Selection criteria  Systematic reviews, randomised controlled trials and other research methods such as non-randomised controlled trials, longitudinal studies, cohort or case-control studies, or descriptive studies that evaluate strategies to identify and manage medication incidents. Those people who are involved in the prescribing, dispensing or administering of medication to the older persons (aged 65 years and older) in the acute, subacute or residential care settings were included. Where these studies were limited, evidence available on the general patient population was used. Data collection and analysis  Study design and quality were tabulated and relative risks, odds ratios, mean differences and associated 95% confidence intervals were calculated from individual comparative studies containing count data where possible. All other data were presented in a narrative summary. Results  Strategies that have some evidence for reducing medication incidents are: •  computerised physician ordering entry systems combined with clinical decision support systems; •  individual medication supply systems when compared with other dispensing systems such as ward stock approaches; •  use of clinical pharmacists in the inpatient setting; •  checking of medication orders by two nurses before dispensing medication; •  a Medication Administration Review and Safety committee; and •  providing bedside glucose monitors and educating nurses on importance of timely insulin administration. In general, the evidence for the effectiveness of intervention strategies to reduce the incidence of medication errors is weak and high-quality controlled trials are needed in all areas of medication prescription and delivery.

Going blank: factors contributing to interruptions to nurses' work and related outcomes

AIM

To examine interruptions to nurses' work, the systems issues related to these and the associated outcomes.

BACKGROUND

While some research has described the role interruptions play in medication errors, work is needed to examine specific factors in the nursing work environment that cause interruptions and to assess the impact of these on nurses' work and patient outcomes.

METHODS

The present study utilized a mixed method design that involved work observation to detect nursing interruptions in the workplace followed by focus groups with a subsample of nurses.

RESULTS

A total of 13,025 interruptions were observed. Equal numbers of these took place on medical and surgical units. The predominant source of interruptions was members of the health team, who interrupted more frequently on medical units.

CONCLUSIONS

Differences in the type of patient and the care needs between medical and surgical units may be a contributing factor to these findings. As members of the health team were among the leading source of interruptions, an interdisciplinary team-based approach to changing the organization and design of work should be explored.

IMPLICATIONS FOR NURSING MANAGEMENT

Nurse leaders should examine ways in which nurses' work can benefit from system improvements to reduce interruptions that lead to patient safety issues such as treatment delays and loss of concentration.

A literature review of the individual and systems factors that contribute to medication errors in nursing practice

AIM

This paper reports a review of the empirical literature on factors that contribute to medication errors.

BACKGROUND

Medication errors are a significant cause of morbidity and mortality in hospitalized patients. This creates an imperative to reduce medication errors to deliver safe and ethical care to patients.

METHOD

The databases CINAHL, PubMed, Science Direct and Synergy were searched from 1988 to 2007 using the keywords medication errors, medication management, medication reconciliation, medication knowledge and mathematical skills, and reporting medication errors. RESULTS Contributory factors to nursing medication errors are manifold, and include both individual and systems issues. These include medication reconciliation, the types of drug distribution system, the quality of prescriptions, and deviation from procedures including distractions during administration, excessive workloads, and nurse's knowledge of medications.

IMPLICATIONS FOR NURSING MANAGEMENT

It is imperative that managers implement strategies to reduce medication errors including the establishment of reporting mechanisms at international and national levels to include the evaluation and audit of practice at a local level. Systematic approaches to medication reconciliation can also reduce medication error significantly. Promoting consistency between health care professionals as to what constitutes medication error will contribute to increased accuracy and compliance in reporting of medication errors, thereby informing health care policies aimed at reducing the occurrence of medication errors. Acquisition and maintenance of mathematical competency for nurses in practice is an important issue in the prevention of medication error. The health care industry can benefit from learning from other high-risk industries such as aviation in the prevention and management of systems errors.

Using snowball sampling method with nurses to understand medication administration errors

AIMS AND OBJECTIVES

We aimed to encourage nurses to release information about drug administration errors to increase understanding of error-related circumstances and to identify high-alert situations.

BACKGROUND

Drug administration errors represent the majority of medication errors, but errors are underreported. Effective ways are lacking to encourage nurses to actively report errors.

METHODS

Snowball sampling was conducted to recruit participants. A semi-structured questionnaire was used to record types of error, hospital and nurse backgrounds, patient consequences, error discovery mechanisms and reporting rates.

RESULTS

Eighty-five nurses participated, reporting 328 administration errors (259 actual, 69 near misses). Most errors occurred in medical surgical wards of teaching hospitals, during day shifts, committed by nurses working fewer than two years. Leading errors were wrong drugs and doses, each accounting for about one-third of total errors. Among 259 actual errors, 83.8% resulted in no adverse effects; among remaining 16.2%, 6.6% had mild consequences and 9.6% had serious consequences (severe reaction, coma, death). Actual errors and near misses were discovered mainly through double-check procedures by colleagues and nurses responsible for errors; reporting rates were 62.5% (162/259) vs. 50.7% (35/69) and only 3.5% (9/259) vs. 0% (0/69) were disclosed to patients and families. High-alert situations included administration of 15% KCl, insulin and Pitocin; using intravenous pumps; and implementation of cardiopulmonary resuscitation (CPR).

CONCLUSIONS

Snowball sampling proved to be an effective way to encourage nurses to release details concerning medication errors. Using empirical data, we identified high-alert situations. Strategies for reducing drug administration errors by nurses are suggested.

RELEVANCE TO CLINICAL PRACTICE

Survey results suggest that nurses should double check medication administration in known high-alert situations. Nursing management can use snowball sampling to gather error details from nurses in a non-reprimanding atmosphere, helping to establish standard operational procedures for known high-alert situations.

A Medication Safety Education Program to Reduce the Risk of Harm Caused by Medication Errors

A medication safety education program was developed and implemented to reduce the harm caused to patients by medication errors, specifically errors related to the intravenous infusion of high-alert medications. Participants were required to complete two 30-minute computer modules focusing on medication safety. Changes in the climate of safety, nurses' knowledge and behavior, and the number of infusion pump alerts and reported medication errors were evaluated both before and after completion of the education program. A statistically significant change in knowledge regarding medication errors occurred, but there was no change in the climate of safety scores, the use of behaviors advocated in the medication safety education program to improve medication infusion safety, the number of infusion pump alerts, or the number of reported errors. It was concluded that there was a need for strong administrative support and follow-up to foster changes in behavior, which can lead to a reduction in harm caused by medication errors.

Documentation of medication management by graduate nurses in patient progress notes: a way forward for patient safety

Nursing documentation provides evidence of nurses' management, the patient response, and evaluation of care. The aim of the study was to examine how graduate nurses document their medication management in the progress notes. A prospective clinical audit of patient medication charts and the progress notes made by 12 graduate nurses was undertaken. Graduate nurses were also individually interviewed and asked clarifying questions about their medication management. Documentation was examined based on four areas: assessment, planning care, administration of medications, and evaluating outcomes of medications. Recorded information about assessment focused on cues of a biomedical rather than a psychosocial nature. Planning care involved non-specific documentation of discharge planning needs, and little information about communication with doctors, pharmacists, nurses, patients and next of kin. Administration of medications included details about the names of medications given to patients, but no information about medication education provided to patients during this time. Evaluation of outcomes of medication administration was poorly documented. Graduate nurses tended to focus on assessing medications before their administration without considering how the patient responded to treatment. Recommendations are proposed for improving the quality of graduate nurses' progress notes. These recommendations include implementing and evaluating protocols that link nurses' decision-making to documentation processes. Adopting a supportive multidisciplinary approach to quality improvement and providing education that emphasises written documentation of verbal communication are also recommended.

Evidence and expertise

This paper evaluates attempts to defend established concepts of expertise and clinical judgement against the incursions of evidence-based practice. Two related arguments are considered. The first suggests that standard accounts of evidence-based practice imply an overly narrow view of 'evidence', and that a more inclusive concept, incorporating 'patterns of knowing' not recognised by the familiar evidence hierarchies, should be adopted. The second suggests that statistical generalisations cannot be applied non-problematically to individual patients in specific contexts, and points out that this is why we need clinical judgement. In evaluating the first argument, I propose a criterion for what counts as evidence. It is a minimalist criterion but the 'patterns of knowing', referred to in the literature, still fail to meet it. In evaluating the second argument, I will outline the powerful empirical reasons we have for thinking that decisions based on research evidence are usually better than decisions based on clinical judgement; and show that current efforts to rehabilitate clinical judgement seriously underestimate the strength of these reasons. By way of conclusion, I will sketch the ways in which the concept of expertise will have to be modified if we accept evidence-based practice as a template for health-care.

Creating an Organizational Culture for Medication Safety

Medication errors are costly from human, economic, and societal perspectives. All patients are vulnerable to the detrimental effects of these errors. Recommendations regarding the problem of medication errors include: Prevention of error by learning from the nonpunitive reporting of errors and near misses; Evaluation of the system for potential causes of error through failure mode and effects analysis and encouragement of a questioning attitude; Elimination of system problems that increase the risk of error; Recognition that humans are fallible and that error will occur even in a perfect system; Minimization of the consequences of errors when they do occur. An important goal for healthcare organizations should be to create a culture that accepts the imperfection of human performance and solicits the assistance of team members in the development of safeguards for error prevention. Proposed interventions to prevent medication errors can be described by the PATIENT SAFE taxonomy, which includes: Patient participation; Adherence to established policy and procedures; Technology use; Information accessibility; Education regarding medication safety; Nonpunitive approach to reporting of errors and near misses; Teamwork, communication, and collaboration; Staffing: adequate number and staffing mix; Administration support for the clinical goal of patient safety; Failure mode and effects analysis with team member involvement; Environment and equipment to support patient safety

Penetration of medication safety technology in community hospitals

Results of a survey of medication safety technology in community hospitals are presented. A written questionnaire was mailed to pharmacy directors at 88 hospitals located in 21 states. Items in the questionnaire addressed current and planned use of technology intended to improve medication safety. Fifty-six usable responses were received for a response rate of 63.6%. Medication safety was considered one of the most important issues facing pharmacy departments. Barriers identified by respondents to the implementation of medication safety initiatives included lack of time and personnel. Most hospitals had implemented one or more different types of medication safety technology. Computer-generated or electronic medication administration records, pharmacy computer systems interfaced with laboratory values, and unit-based medication dispensing cabinets were the most common medication safety technologies used. Pharmacy managers perceived these technologies to have resulted in a reduction in the rate of medication errors in respondent hospitals.
