Medication errors in the intensive care unit: literature review using the SEIPS model

Designing Human-Centered AI to Prevent Medication Dispensing Errors: Focus Group Study With Pharmacists

BACKGROUND

Medication errors, including dispensing errors, represent a substantial worldwide health risk with significant implications in terms of morbidity, mortality, and financial costs. Although pharmacists use methods like barcode scanning and double-checking for dispensing verification, these measures exhibit limitations. The application of artificial intelligence (AI) in pharmacy verification emerges as a potential solution, offering precision, rapid data analysis, and the ability to recognize medications through computer vision. For AI to be embraced, it must be designed with the end user in mind, fostering trust, clear communication, and seamless collaboration between AI and pharmacists.

OBJECTIVE

This study aimed to gather pharmacists' feedback in a focus group setting to help inform the initial design of the user interface and iterative designs of the AI prototype.

METHODS

A multidisciplinary research team engaged pharmacists in a 3-stage process to develop a human-centered AI system for medication dispensing verification. To design the AI model, we used a Bayesian neural network that predicts the dispensed pills' National Drug Code (NDC). Discussion scripts regarding how to design the system and feedback in focus groups were collected through audio recordings and professionally transcribed, followed by a content analysis guided by the Systems Engineering Initiative for Patient Safety and Human-Machine Teaming theoretical frameworks.

RESULTS

A total of 8 pharmacists participated in 3 rounds of focus groups to identify current challenges in medication dispensing verification, brainstorm solutions, and provide feedback on our AI prototype. Participants considered several teaming scenarios, generally favoring a hybrid teaming model where the AI assists in the verification process and a pharmacist intervenes based on medication risk level and the AI's confidence level. Pharmacists highlighted the need for improving the interpretability of AI systems, such as adding stepwise checkmarks, probability scores, and details about drugs the AI model frequently confuses with the target drug. Pharmacists emphasized the need for simplicity and accessibility. They favored displaying only essential information to prevent overwhelming users with excessive data. Specific design features, such as juxtaposing pill images with their packaging for quick comparisons, were requested. Pharmacists preferred accept, reject, or unsure options. The final prototype interface included (1) checkmarks to compare pill characteristics between the AI-predicted NDC and the prescription's expected NDC, (2) a histogram showing predicted probabilities for the AI-identified NDC, (3) an image of an AI-provided "confused" pill, and (4) an NDC match status (ie, match, unmatched, or unsure).

CONCLUSIONS

In partnership with pharmacists, we developed a human-centered AI prototype designed to enhance AI interpretability and foster trust. This initiative emphasized human-machine collaboration and positioned AI as an augmentative tool rather than a replacement. This study highlights the process of designing a human-centered AI for dispensing verification, emphasizing its interpretability, confidence visualization, and collaborative human-machine teaming styles.

Generic analysis method to learn from serious adverse events in Dutch hospitals: a human factors perspective

Background

Hospitals in various countries such as the Netherlands investigate and analyse serious adverse events (SAEs) to learn from previous events and attempt to prevent recurrence. However, current methods for SAE analysis do not address the complexity of healthcare and investigations typically focus on single events on the hospital level. This hampers hospitals in their ambition to learn from SAEs. Integrating human factors thinking and using a holistic and more consistent method could improve learning from SAEs.

Aim

This study aims to develop a novel generic analysis method (GAM) to: (1) facilitate a holistic event analysis using a human factors perspective and (2) ease aggregate analysis of events across hospitals.

Methods

Multiple steps of carefully evaluating, testing and continuously refining prototypes of the method were performed. Various Dutch stakeholders in the field of patient safety were involved in each step. Theoretical experts were consulted, and the prototype was pretested using information-rich SAE reports from Dutch hospitals. Expert panels, engaging quality and safety experts and medical specialists from various hospitals were consulted for face and content validity evaluation. User test sessions concluded the development of the method.

Results

The final version of the GAM consists of a framework and affiliated questionnaire. GAM combines elements of three methods for SAE analysis currently practised by Dutch hospitals. It is structured according to the Systems Engineering Initiative for Patient Safety model, which incorporates a human factors perspective into the analysis. These eases aggregated analysis of SAEs across hospitals and helps to consider the complexity of healthcare work systems.

Conclusion

The GAM is a valuable new tool for hospitals to learn from SAEs. The method can facilitate a holistic aggregate analysis of SAEs across hospitals using a human factors perspective, and is now ready for further extensive testing.

Risk factors associated with medication ordering errors

OBJECTIVE

We utilized a computerized order entry system-integrated function referred to as "void" to identify erroneous orders (ie, a "void" order). Using voided orders, we aimed to (1) identify the nature and characteristics of medication ordering errors, (2) investigate the risk factors associated with medication ordering errors, and (3) explore potential strategies to mitigate these risk factors.

MATERIALS AND METHODS

We collected data on voided orders using clinician interviews and surveys within 24 hours of the voided order and using chart reviews. Interviews were informed by the human factors-based SEIPS (Systems Engineering Initiative for Patient Safety) model to characterize the work systems-based risk factors contributing to ordering errors; chart reviews were used to establish whether a voided order was a true medication ordering error and ascertain its impact on patient safety.

RESULTS

During the 16-month study period (August 25, 2017, to December 31, 2018), 1074 medication orders were voided; 842 voided orders were true medication errors (positive predictive value = 78.3 ± 1.2%). A total of 22% (n = 190) of the medication ordering errors reached the patient, with at least a single administration, without causing patient harm. Interviews were conducted on 355 voided orders (33% response). Errors were not uniquely associated with a single risk factor, but the causal contributors of medication ordering errors were multifactorial, arising from a combination of technological-, cognitive-, environmental-, social-, and organizational-level factors.

CONCLUSIONS

The void function offers a practical, standardized method to create a rich database of medication ordering errors. We highlight implications for utilizing the void function for future research, practice and learning opportunities.

Medication errors in prescription and administration in critically ill patients

AIM

To determine the prevalence and magnitude of medication errors and their association with patients' sociodemographic and clinical characteristics and nurses' work conditions.

DESIGN

An observational, analytical, cross-sectional and ambispective study was conducted in critically ill adult patients.

METHODS

Data concerning prescription errors were collected retrospectively from medical records and administration errors were identified through direct observation of nurses during drug administration. Those data were collected between April and July 2015.

RESULTS

A total of 650 prescription errors were identified for 961 drugs in 90 patients (mean error 7[SD 4.1] per patient) and prevalence of 47.1% (95% CI 44-50). The most frequent error was omission of the prescribed medication. Intensive care unit stay was a risk factor associated with omission error (OR 2.14; 1.46-3.14: p < .01). A total of 294 administration errors were identified for 249 drugs in 52 patients (mean error 6 [SD 6.7] per patient) and prevalence of 73.5% (95% CI 68-79). The most frequent error was interruption during drug administration. Admission to the intensive care unit (OR 0.37; 0.21-0.66: p < .01), nurses' morning shift (OR 2.15; 1.10-4.18: p = .02) and workload perception (OR 3.64; 2.09-6.35: p < .01) were risk factors associated with interruption.

CONCLUSIONS

Medication errors in prescription and administration were frequent. Timely detection of errors and promotion of a medication safety culture are necessary to reduce them and ensure the quality of care in critically ill patients.

IMPACT

Medication errors occur frequently in the intensive care unit but are not always identified. Due to the vulnerability of seriously ill patients and the specialized care they require, an error can result in serious adverse events. The study shows that medication errors in prescription and administration are recurrent but preventable. These findings contribute to promote awareness in the proper use of medications and guarantee the quality of nursing care.

Medication errors and drug knowledge gaps among critical-care nurses: a mixed multi-method study

BACKGROUND

Medication errors are a serious and complex problem in clinical practice, especially in intensive care units whose patients can suffer potentially very serious consequences because of the critical nature of their diseases and the pharmacotherapy programs implemented in these patients. The origins of these errors discussed in the literature are wide-ranging, although far-reaching variables are of particular special interest to those involved in training nurses. The main objective of this research was to study if the level of knowledge that critical-care nurses have about the use and administration of medications is related to the most common medication errors.

METHODS

This was a mixed (multi-method) study with three phases that combined quantitative and qualitative techniques. In phase 1 patient medical records were reviewed; phase 2 consisted of an interview with a focus group; and an ad hoc questionnaire was carried out in phase 3.

RESULTS

The global medication error index was 1.93%. The main risk areas were errors in the interval of administration of antibiotics (8.15% error rate); high-risk medication dilution, concentration, and infusion-rate errors (2.94% error rate); and errors in the administration of medications via nasogastric tubes (11.16% error rate).

CONCLUSIONS

Nurses have a low level of knowledge of the drugs they use the most and with which a greater number of medication errors are committed in the ICU.

Exploring leadership within a systems approach to reduce health care-associated infections: A scoping review of one work system model

BACKGROUND

Despite efforts to prevent health care-associated infections (HAIs), these infections continue to challenge health care systems. The Centers for Disease Control and Prevention emphasizes implementation of evidence-based practices. Within the complex health care environment, sustained implementation calls for work systems that harness expertise of interprofessional teams, which, in turn, calls for suitable executive, mid-level, and local leadership. The purpose of this review is to highlight the need to study leadership when using a systems approach to reduce HAIs.

METHODS

This is a scoping review of HAI studies that used a systems engineering model called the Systems Engineering Initiative for Patient Safety model. We examined if and how leadership was addressed within 1 systems approach.

RESULTS

We found 15 studies using the Systems Engineering Initiative for Patient Safety model and, of these, leadership was directly mentioned in 3 studies. In the remaining studies, reference to leadership may be inferred by use of terms such as teamwork, managerial oversight, climate and culture, staffing support, and institutional/administrative support.

CONCLUSIONS

Research is needed to bring recognition of the role of leadership within a work systems approach to reducing HAIs. We need further examination of leadership attributes and communication behaviors that allow staff to diffuse and sustain best practices to prevent HAIs.

Application of the SEIPS Model to Analyze Medication Safety in a Crisis Residential Center

PURPOSE

Medication safety and error reduction has been studied in acute and long-term care settings, but little research is found in the literature regarding mental health settings. Because mental health settings are complex, medication administration is vulnerable to a variety of errors from transcription to administration. The purpose of this study was to analyze critical factors related to a mental health work system structure and processes that threaten safe medication administration practices.

BACKGROUND

The Systems Engineering Initiative for Patient Safety (SEIPS) model provides a framework to analyze factors affecting medication safety. The model approach analyzes the work system concepts of technology, tasks, persons, environment, and organization to guide the collection of data.

METHODS

In the study, the Lean methodology tools were used to identify vulnerabilities in the system that could be targeted later for improvement activities. The project director completed face-to-face interviews, asked nurses to record disruptions in a log, and administered a questionnaire to nursing staff. The project director also conducted medication chart reviews and recorded medication errors using a standardized taxonomy for errors that allowed categorization of the prevalent types of medication errors.

RESULTS

Results of the study revealed disruptions during the medication process, pharmacology training needs, and documentation processes as the primary opportunities for improvement. The project engaged nurses to identify sustainable quality improvement strategies to improve patient safety.

CONCLUSION

The mental health setting carries challenges for safe medication administration practices. Through analysis of the structure, process, and outcomes of medication administration, opportunities for quality improvement and sustainable interventions were identified, including minimizing the number of distractions during medication administration, training nurses on psychotropic medications, and improving the documentation system. A task force was created to analyze the descriptive data and to establish objectives aimed at improving efficiency of the work system and care process involved in medication administration at the end of the project.

Nurse compliance with a protocol for safe injectable medication administration: comparison of two multicentre observational studies

OBJECTIVES

Medication administration errors with injectable medication have a high risk of causing patient harm. To reduce this risk, all Dutch hospitals implemented a protocol for safe injectable medication administration. Nurse compliance with this protocol was evaluated as low as 19% in 2012. The aim of this second evaluation study was to determine whether nurse compliance had changed over a 4-year period, what factors were associated over time with protocol compliance and which strategies have been implemented by hospitals to increase protocol compliance.

METHODS

In this prospective observational study, conducted between November 2015 and September 2016, nurses from 16 Dutch hospitals were directly observed during intravenous medication administration. Protocol compliance was complete if nine protocol proceedings were conducted correctly. Protocol compliance was compared with results from the first evaluation. Multilevel logistic regression analyses were used to assess the associations over time between explanatory variables and complete protocol compliance. Implemented strategies were classified according to the five components of the Systems Engineering Initiative for Patient Safety (SEIPS) model.

RESULTS

A total of 372 intravenous medication administrations were observed. In comparison with 2012, more proceedings per administration were conducted (mean 7.6, 95% CI 7.5 to 7.7 vs mean 7.3, 95% CI 7.3 to 7.4). No significant change was seen in complete protocol compliance (22% in 2016); compliance with the proceedings 'hand hygiene' and 'check by a second nurse' remained low. In contrast to 2012, the majority of the variance was caused by differences between wards rather than between hospitals. Most implemented improvement strategies targeted the organisation component of the SEIPS model.

CONCLUSIONS

Compliance with 'hand hygiene' and 'check by a second nurse' needs to be further improved in order to increase complete protocol compliance. To do so, interventions focused on nurses and individually tailored to each ward are needed.

Knowledge, behaviours, training and attitudes of nurses during preparation and administration of intravenous medications in intensive care units (ICU). A multicenter Italian study

BACKGROUND

Medication errors can put at risk the life of patients hospitalized in the ICUs. These errors occur more frequently in the ICUs due to their peculiar medical framework. There is not much information about the knowledge, attitudes, behaviours and training needs of the nurses who work in ICUs towards the medication errors.

OBJECTIVE

This study aims at describing the knowledge, attitudes, behaviours and training needs of the Italian nurses who work in ICUs towards the use of IV drugs, and identifying the strategies that nurses can adopt to prevent the occurrence of medication errors.

MATERIALS AND METHODS

Cross-sectional study. The survey was carried out through a self-administrated questionnaire and it was addressed to 529 Italian nurses who work in the ICUs of Southern, Centre and Northern Italy hospitals (average age of the sample 39.9, SD=9.1, 68.1% females). The questionnaire, made of 36 items divided into 7 sections, was validated after the results of the pilot study.

RESULTS

The study highlighted the importance of the role, behaviours and knowledge of the nurses to prevent the medication errors. The results of the multivariate analysis of the multicentre study show a relation among correct behaviours and positive attitudes, even if it is not statistically significant. Worth mentioning is the fact that the achievement of a university degree affects negatively the correct behaviours (OR 0.56, 95% CI 0.34-0.95), as well as the years of work (OR 0.97, 95% CI 0.94-0.99).

CONCLUSIONS

The results of this multicentre study are encouraging. Nurses who have a good command of the English language (sufficient, good, and excellent) dedicate more than an hour per week to the bibliography update. Extending and deepening the knowledge of the nurses in a cyclical way might be an effective strategy to keep a high level of security of the drugs in the ICUs. The study highlighted that almost all the surveyed nurses (93%) are aware that an adequate knowledge of the drugs dosage calculation is essential to reduce the occurrence of medication errors in the drugs preparation phase.

The culture contributing to interruptions in the nursing work environment: An ethnography

AIMS AND OBJECTIVES

To understand the occurrence of interruptions within the culture of the medical nursing unit work environment.

BACKGROUND

Interruptions may lead to errors in nursing work. Little is known about how the culture of the nursing work environment contributes to interruptions.

DESIGN

A micro-focused ethnographic study was conducted.

METHOD

Data collection involved extensive observation of a nursing unit, 1:1 observations of nurses and follow-up interviews with the nurses. Data were analysed from unstructured field notes and interview transcripts. The definitions of interruption and culture guided coding, categorising and identification of themes.

RESULTS

A framework was developed that describes the medical nursing unit as a complex culture full of unpredictable, nonlinear changes that affect the entire interconnected system, often in the form of an interruption. The cultural elements contributing to interruptions included (i) the value placed on excellence in patient care and meeting personal needs, (ii) the beliefs that the nurses had to do everything by themselves and that every phone call was important, (iii) the patterns of changing patients, patient transport and coordination of resources and (iv) the normative practices of communicating and adapting.

CONCLUSIONS

Interruptions are an integral part of the culture of a medical nursing unit. Uniformly decreasing interruptions may disrupt current practices, such as communication to coordinate care, that are central to nursing work. In future research, the nursing work environment must be looked at through the lens of a complex system.

RELEVANCE TO CLINICAL PRACTICE

Interventions to minimise the negative impact of interruptions must take into account the culture of the nursing as a complex adaptive system. Nurses should be educated on their own contribution to interruptions and issues addressed at a system level, rather than isolating the interruption as the central issue.

Facilitated Nurse Medication-Related Event Reporting to Improve Medication Management Quality and Safety in Intensive Care Units

BACKGROUND

Medication safety presents an ongoing challenge for nurses working in complex, fast-paced, intensive care unit (ICU) environments. Studying ICU nurse's medication management-especially medication-related events (MREs)-provides an approach to analyze and improve medication safety and quality.

OBJECTIVES

The goal of this study was to explore the utility of facilitated MRE reporting in identifying system deficiencies and the relationship between MREs and nurses' work in the ICUs.

METHODS

We conducted 124 structured 4-hour observations of nurses in three different ICUs. Each observation included measurement of nurse's moment-to-moment activity and self-reports of workload and negative mood. The observer then obtained MRE reports from the nurse using a structured tool. The MREs were analyzed by three experts.

RESULTS

MREs were reported in 35% of observations. The 60 total MREs included four medication errors and seven adverse drug events. Of the 49 remaining MREs, 65% were associated with negative patient impact. Task/process deficiencies were the most common contributory factor for MREs. MRE occurrence was correlated with increased total task volume. MREs also correlated with increased workload, especially during night shifts.

DISCUSSION

Most of these MREs would not be captured by traditional event reporting systems. Facilitated MRE reporting provides a robust information source about potential breakdowns in medication management safety and opportunities for system improvement.

Learning to manage vasoactive drugs-A qualitative interview study with critical care nurses

OBJECTIVE

Being a nurse in an intensive care unit entails caring for seriously ill patients. Vasoactive drugs are one of the tools that are used to restore adequate circulation. Critical care nurses often manage and administer these potent drugs after medical advice from physicians.

AIM

To describe the experiences of critical care nurses learning to manage vasoactive drugs, and to highlight the competence required to manage vasoactive drugs.

RESEARCH METHODOLOGY/SETTING

Twelve critical care nurses from three hospitals in Sweden were interviewed. Qualitative content analysis was applied.

RESULTS

The theme "becoming proficient requires accuracy, practice and precaution" illustrated how critical care nurses learn to manage vasoactive drugs. Learning included developing cognitive, psychomotor, and effective skills. Sources for knowledge refers to specialist education combined with practical exercises, collegial support, and accessible routine documents. The competence required to manage vasoactive drugs encompassed well-developed safety thinking that included being careful, in control, and communicating failures. Specific skills were required such as titrating doses, being able to analyse and evaluate the technological assessments, adapting to the situation, and staying calm.

CONCLUSION

Learning to manage vasoactive drugs requires a supportive introduction for novices, collegial support, lifelong learning, and a culture of safety.

Measuring the impact of an interprofessional multimedia learning resource on Japanese nurses and nursing students using the Theory of Planned Behavior Medication Safety Questionnaire

Interprofessional communication and teamwork are essential for medication safety; however, limited educational opportunities for health professionals and students to develop these skills exist in Japan. This study evaluated the impact of an interprofessional multimedia learning resource on registered nurses' and nursing students' intention to practice in a manner promoting medication safety. Using a quasi-experimental design, Japanese registered nurses and nursing students (n = 203) were allocated to an experimental (n = 109) or control group (n = 94). Behavioral intentions of medication safety and the predictor variables of attitudes, perceived behavioral control, and subjective norms were measured using a Japanese version of the Theory of Planned Behavior Medication Safety Questionnaire. Registered nurses in the experimental group demonstrated a greater intention to collaborate and practice in a manner that enhanced medication safety, evidenced by higher scores than the control group on all predictor variables. The results demonstrate the potential for interprofessional multimedia learning resources to positively impact the behaviors of Japanese registered nurses in relation to safe medication practices. Further research in other contexts and with other cohorts is warranted.

Survey of Nursery Errors in Healthcare Centers, Isfahan, Iran

Background & Aim:

Nurse's mistakes usually have a strong effect on the patients trust and satisfaction in the health services systems, and it can also lead to stress and moral contradicts among nurses. This study has aimed to survey the rate of nurses’ mistakes, according to documents in the Isfahan Province during 2007-2012.

Methods:

The study was a descriptive cross-sectional study. The sample population consisted of all complaints concerning nursing services provided in hospitals, private clinics and other health service centers between 2007 and 2012, submitted to the Forensic Medicine Commission Office, in Isfahan. The data were collected by a cheklist and analyzed using SPSS version 16.0 software.

Results:

Out of 708 complaints, 70 (9.8%) cases were related to nurses. Twenty-four cases led to awards. The age range of nurses was 35-40 (25.7%). Out of 70 nurses with a record, 75% (53 people) were female and the rest were male. Sixty four nurses (91.4%) were working in hospitals. Negligence was the first basis of the court rulings (16 cases out of 24). Nurses’ recklessness in providing services was due to their convictions among 66.7% of the cases

Conclusion:

Although efforts to reduce and control nurses’ faults and mistakes depends on using a system for studying and removing the factors which lead to faults, human error is inevitable in every occupation and a 100% accurate operation is unreachable.

Implementation of pharmacists' interventions and assessment of medication errors in an intensive care unit of a Chinese tertiary hospital

Background

Pharmacist interventions and medication errors potentially differ between the People’s Republic of China and other countries. This study aimed to report interventions administered by clinical pharmacists and analyze medication errors in an intensive care unit (ICU) in a tertiary hospital in People’s Republic of China.

Method

A prospective, noncomparative, 6-month observational study was conducted in a general ICU of a tertiary hospital in the People’s Republic of China. Clinical pharmacists performed interventions to prevent or resolve medication errors during daily rounds and documented all of these interventions and medication errors. Such interventions and medication errors were categorized and then analyzed.

Results

During the 6-month observation period, a total of 489 pharmacist interventions were reported. Approximately 407 (83.2%) pharmacist interventions were accepted by ICU physicians. The incidence rate of medication errors was 124.7 per 1,000 patient-days. Improper drug frequency or dosing (n=152, 37.3%), drug omission (n=83, 20.4%), and potential or actual occurrence of adverse drug reaction (n=54, 13.3%) were the three most commonly committed medication errors. Approximately 339 (83.4%) medication errors did not pose any risks to the patients. Antimicrobials (n=171, 35.0%) were the most frequent type of medication associated with errors.

Conclusion

Medication errors during prescription frequently occurred in an ICU of a tertiary hospital in the People’s Republic of China. Pharmacist interventions were also efficient in preventing medication errors.
