Evaluation of the safety of medication-use systems in hospital emergency services. / Evaluación de la seguridad del sistema de utilización de los medicamentos en los servicios de urgencias hospitalarios.

INTRODUCTION: The aim of this study was to assess the implementation of safe medication practices in hospital emergency services, in order to understand the points of greatest risk as well as the safety challenges faced by these departments, and to plan collaboratively improvement initiatives. METHOD: Multicentric and descriptive study based on completion of the "Medication safety self-assessment of emergency services" from 5/16/2023 to 11/16/2023, at voluntarily participating emergency services. The survey contained 93 items grouped into 10 key elements. Mean score and mean percentages based on the maximum possible values for the overall survey, for the key elements and for each individual item of evaluation, were assessed. RESULTS: A total of 72 emergency services completed the questionnaire. The mean score obtained for the overall questionnaire was 428.3 points (51.1% of the maximum score). Results showed a large variation among the scores of the participating services (range: 164-620.5). Four key elements had values below 50%, corresponding to competence and training of professionals in safety practices (38.4%); incorporation of pharmacists in emergency departments (42.1%), availability and accessibility of information about patients (43.1%), and patient education (48.1%). The highest values corresponded to labeling, packaging, and naming of medications (69.2%) and communication of prescriptions and other medication information (64%). No differences were found between emergency services in the key elements according to the dependency or size of the hospital, or the type of service, except for the item referring to the incorporation of pharmacists in the emergency service, where differences were observed between hospitals with less than 200 beds (28.9%) and those with more than 500 (52.2%). CONCLUSION: The application of the specific self-assessment questionnaire has made it possible to identify safety practices that are insufficiently implemented into emergency services in our country and to identify critical points for improvement for which planning collaborative initiatives to reduce medication errors in these departments should become a priority.

Simulated medication administration for vulnerable populations using scanning technology: a quasi-experimental pilot study.

BACKGROUND: Medication errors may occur due to shortcuts and pressures on time and resources on nurses. Nursing students are enculturated into these environments where their perceptions of norms around reporting and responding to medication errors are formative, yet simulated medication administration experiences are rarely reflective of the real-world environment. such as the standard use of medication scanning technology. The purpose of the present study is to test a pilot intervention, Medication Quick Response (QR) code scanning, and evaluate its effect on medication errors during simulation when compared to traditional simulation medication administration practices and to assess the students' perceptions of the intervention. METHODS: We conducted a quasi-experimental, observational study involving Junior and Senior (3rd and 4th year) undergraduate, pre-licensure nursing students from Spring 2022 until Fall 2023. Seven simulations were conducted in pediatric and obstetric courses. The intervention group used non-patented, low cost QR scanning during medication administration. The control group used standard manual administration. Medication errors were measured based on the quantity, type of error, and degree of patient risk. A Qualtrics survey was used to assess the students' perceptions of the intervention following simulation participation. RESULTS: A total of 166 students participated in the study. In each course, 7 groups were assigned to the intervention and 8 were assigned to the control. More than half of the groups made at least one medication error (n = 17), one-third of groups (n = 10) made a high-risk medication error. There was no statistically meaningful difference in the rate, type, or potential patient risk of medication errors between the intervention and control groups. The majority of participants (n = 53) felt that QR scanning more closely mimicked medication administration in clinical settings. Half of the participants responded that it improved their safety practices (n = 37). CONCLUSIONS: The results of this pilot study indicate that while there is a high risk for error among pre-licensure nursing students, the use of QR scanning did not increase the risk of medication errors. The next study iteration will build upon these pilot findings to integrate the use of embedded medication errors, time management tasks, and a multi-site implementation.

[Dispensing Service: An Essential Service Provided by Community Pharmacy to Enhance Patient Safety. A Case Study]. / Servicio de Dispensación: un servicio esencial brindado desde la Farmacia Comunitaria que permite reforzar la Seguridad del Paciente. A propósito de un caso.

A 38-year-old patient diagnosed with asthma and anxiety, who takes two medications (salbutamol 100 mcg inhaler (2 puffs every 6 hours), and diazepam 5 mg (0-0-1), visited the Community Pharmacy to pick up a treatment prescribed by the Primary Care Physician (PCP) following a diagnosis of anxious-depressive symptoms.During the Dispensing Service, a potential Drug-Related Problem (DRP) of prescription error is detected, which could be related with a Negative Outcomes Releated to Medicines (NOM) due to the concurrent use of desvenlafaxine and mirtazapine. Additionally, a Health Problem (HP)-related DRP was detected, as the proposal to discontinue the use of diazepam could result in an Insufficiently Treated HP, potentially leading to a NOM of Treatment Necessity due to the risk of worsening anxiety episodes.From de Community Pharmacy, a report was prepared with recommendations that were accepted by the PCP. Subsequent case monitoring revealed an improved management of the patient's health problems, as well as the resolution of the identified DRP and NOM. This ensured a rational, safe, and effective use of the medication.

Characteristics and causes of reported clozapine-related medication errors: analysis of the Ministry of Health database in Saudi Arabia.

BACKGROUND: Clozapine has shown great efficacy in treating treatment-resistant schizophrenia, but it is associated with a variety of medication- related safety problems. Despite this, there remains a lack of research on medication errors (MEs) associated with its use. AIM: To characterize the nature and contributory factors of clozapine-related MEs reported from government hospitals and primary care centres in Saudi Arabia (SA). METHOD: A cross-sectional analysis was carried out on MEs related to clozapine use reported to the General Administration of Pharmaceutical Care at the Ministry of Health (MOH) in Saudi Arabia between 2018 and 2022. The data were analysed descriptively to examine the nature and contributory factors of MEs. RESULTS: A total of 1,165 MEs were reported. The majority of reported errors involved patients aged > 18 years old, with 72.2% (n = 841) being male. The central region was found to report errors more frequently (32.3%, n = 376). Pharmacists were reported to detect errors most frequently (59.6%, n = 695). MEs most often occurred in the prescribing stage (77.8%, n = 906), with "missing prescription information" (30.1%, n = 351) being the most frequent finding. The most frequent contributing factor was the lack of policy (33.1%, n = 351). The majority of errors did not reach the patients (92.3%, n = 1,075), and those that did reach patients rarely resulted in harm (0.3%, n = 2). CONCLUSION: This study identified areas for improvement which could expedite the development of remedial interventions to reduce the risk of errors.

Analysis of medication errors in Neonatal Intensive Care: A systematic review.

Medication errors, potentially causing harm and causing harm, increase significantly in newborns cared for in intensive care settings. In this sense, this work carries out a systematic review to analyze the most current evidence in relation to medication errors in neonatal intensive care, discussing the topics that refer to health technology from smart pumps, cost-effectiveness of medications, the practice of nursing professionals on the medication administration process and quality improvement models. In this way, it could be considered a useful tool to promote quality and safety in neonatal intensive care.

Antimicrobial infusion practices within intensive care units: Carbapenem infusion preparation and administration process errors.

OBJECTIVE: To describe nurse preparation and administration of intermittent carbapenem infusions. RESEARCH METHODOLOGY/DESIGN: This observational study documented the carbapenem infusion process to adult patients in three general intensive care units. MAIN OUTCOME MEASURES: Timing and duration of infusions were observed. Volumetric analysis of infusion items was conducted to determine loss of reconstituted carbapenem during preparation and administration phases. RESULTS: Carbapenem infusions (n = 223) administered to twenty adult patients were observed. Infusion duration guidance was variable, with two ICUs following current literature recommendations, and one ICU referring to medication package insert information. Within these parameters, only 60 % of infusions complied with infusion duration. Non-compliance with planned time of administration impacted on desired dosing intervals. Incomplete delivery of intended dose was found during: sub-optimal reconstitution of vials, incorrect number of vials reconstituted, failure to administer a dose (missed dose), and discarding antibiotic residue in infusion items. Volumetric analysis of infusion items showed mean dose losses of 4.9 % and 1.2 % in discarded vials and syringes. Mean drug losses of 6.3 % and 30.8 % occurred in discarded infusion bags and infusion lines respectively. No flushing guidance or practice was observed. CONCLUSION: Incorrect nurse administration of antibiotics resulted in varying durations of infusions and the non-delivery of prescribed dose. Under-dosing has the potential to contribute to selection pressure for bacterial antibiotic resistance. The increasing frequency of intravenous delivery of antimicrobial agents through infusions requires an understanding of the required duration of administration and how to manage residual drug remaining in the intravenous line once the infusion is completed. IMPLICATIONS FOR CLINICAL PRACTICE: Flushing of administration lines is not common practice following intermittent antimicrobial infusions. Although there are multi-factorial risk factors for antimicrobial resistance in the critical care arena, nurse infusion practice must ensure that patients receive intended antimicrobial treatment. Attention must be given to the potential for antimicrobial resistance from environmental contamination with the disposal of infusion items containing undelivered antimicrobial medication.

Identifying factors influencing clinicians' reporting of medication errors: a systematic review and qualitative evidence synthesis using the theoretical domains framework.

INTRODUCTION: Medication errors have a significant impact on patient safety and professional practice. The widespread under-reporting of errors by clinicians indicates the critical need for behavioral change. This systematic review aimed to identify and synthesize qualitative evidence on factors influencing clinicians' reporting of medication errors. AREAS COVERED: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, PubMed, and Embase were searched until March 2023 for studies on factors influencing clinicians' reporting of medication errors. Two independent reviewers conducted the screening, data extraction, and quality appraisal. Using framework synthesis approach, the identified themes were mapped to Theoretical Domains Framework (TDF). EXPERT OPINION: The review analyzed fourteen high-quality studies across various regions. Facilitators of reporting were identified in the TDF domains of beliefs about consequences knowledge and social/professional role and identity. More themes emerged as barriers, mapped to the domains of beliefs about consequences, emotions, environmental context and resources and knowledge. The review suggests aligning these barriers with key behavior change techniques, such as emphasizing the risks of non-reporting, promoting emotional well-being, improving accessibility of reporting systems and advancing knowledge through educational programs. Future work should focus on developing these behavior change techniques into practical interventions.

Unintentional Infusion of Insulin Into the Epidural Space During Labor.

Inadvertent injection of drugs into the epidural space has a potential for serious morbidity and is probably underestimated and underreported. A 39-year-old female with no medical history presented for delivery. An epidural catheter was requested and correctly placed. Continuous epidural infusion was chosen for labor analgesia. Six hours after the parturient complained about inefficient analgesia, a syringe swap with insulin was identified. Despite the risk of possibly neurotoxic preservatives in the insulin formulation, no neurological sequelae were observed. This case highlights the issue of wrong-route drug administration and the urgent need to adopt route-specific connections.

Using personal health records for medication continuity during transition of care: An observational study.

Background: National Personal Health Records (PHRs) have been proposed to improve the transfer of medication-related information during transition of care. Objective: To evaluate the concordance between the medications captured in the Australian national PHR, My Health Record (MyHR), and the pharmacist obtained best possible medication history (BPMH) for patients upon hospital admission. Method: This prospective observational study used a convenience sample of hospital patients. For newly admitted patients, the investigating pharmacist obtained a BPMH and then compared it to the medication list captured in MyHR. Upon comparison, the medications were categorised into either complete match, partial match or mismatch. Medications with a complete or partial match were grouped together. Medications with deviations were then assessed for risk based on their potential consequence, and reported descriptively. A multivariable logistic regression was conducted to assess the factors associated with a drug being mismatched. Results: A total of 82 patients were recruited, with a cumulative total of 1,207 medications documented. Of the 1,207 medications, 714 (59.2%) medications were documented as a complete/partial match. The remaining 493 (40.8%) medications were mismatched. Of the 493 mismatched medications, 442 (89.7%) were deemed low-risk deviations and 51 (10.3%) were deemed high-risk. A medication was more likely to be mismatched, rather than completely/partially matched, if it was a regular non-prescription medication, or "when-required" prescription medication, or "when required" non-prescription medication, or if it was administered parenterally. Conclusion: National PHRs may be a secondary source to either confirm a patient's medication history or be used as a starting point for a BPMH.

Drug administration errors among anaesthesia providers in South Africa: a cross-sectional descriptive study.

BACKGROUND: Drug administration errors (DAEs) in anaesthesia are common, the aetiology multifactorial and though mostly inconsequential, some lead to substantial harm. The extend of DAEs remain poorly quantified and effective implementation of prevention strategies sparse. METHOD: A cross-sectional descriptive study was conducted using a peer-reviewed survey questionnaire, circulated to 2217 anaesthetists via a national communication platform. The aim was to determine the self-reported frequency, nature, contributing factors and reporting patterns of DAEs among anaesthesia providers in South Africa. RESULTS: Our cohort had a response rate was 18.9%, with 420 individuals populating the questionnaire. 92.5% of surveyed participants have made a DAE and 89.2% a near-miss. Incorrect route of administration, potentially resulting in serious harm, accounted for 8.2% (n = 23/N = 279) of these errors. DAEs mostly reported in cases involving adult patients (80.5%, n = 243/N = 302), receiving a general anaesthetic (71.8%, n = 216/N = 301), where the drug-administrator prepared the drugs themselves (78.7%, n = 218/N = 277), during normal daytime hours (69.9%, n = 202/N = 289) with good lightning conditions (93.0%, n = 265/N = 285). 26% (n = 80/N = 305) of DAEs involved ampoule misidentification, whilst syringe identification error reported in 51.6% (n = 150/N = 291) of cases. DAEs are often not reported (40.3%, n = 114/N = 283), with knowledge of correct reporting procedures lacking. 70.5% (n = 198/N = 281) of DAEs were never discussed with the patient. CONCLUSIONS: DAEs in anaesthesia remain prevalent. Known error traps continue to drive these incidents. Implementation of system based preventative strategies are paramount to guard against human error. Efforts should be made to encourage scrupulous reporting and training of anaesthesia providers, with the aim of rendering them proficient and resilient to handle these events.

High prevalence of medication errors in a secondary-level Lithuanian hospital: A prospective cross-sectional observational study.

As the population continues to age, the occurrence of chronic illnesses and comorbidities that often necessitate the use of polypharmacy has been on the rise. Polypharmacy, among other factors that tend to coincide with chronic diseases, such as obesity, impaired kidney and liver function, and older age, can increase the risk of medication errors (MEs). Our study aims to evaluate the prevalence of MEs in the Internal medicine, Cardiology, and Neurology departments at the secondary-level university hospital. We conducted a prospective observational study of 145 patients' electronic or paper-based data of inpatient prescriptions and patients' pharmacokinetic risk factors, such as an impairment of renal and/or hepatic function, weight, and age. All included patients collectively received 1252 prescribed drugs. The median (Q1; Q3) number of drugs per patient was 8 (7;10). At least one ME was identified in 133 out of the 145 patients, indicating a significantly higher prevalence than hypothesized (91.7% vs. 50%; p < .001). There was moderate, positive correlation between the quantity of prescribed drugs and the number of MEs, meaning that the more drugs are prescribed, the higher the number of identified MEs (Spearman's ρ = 0.428; p < .001). These findings suggest that there is a need for continuous medication education activity for prescribing physicians, continuous evaluation of prescription appropriateness to objectively identify the MEs and to contribute to more rational patient treatment.

Investigating a Novel Two-Bag N-Acetylcysteine Regimen for Acetaminophen Toxicity.

BACKGROUND: Acetaminophen toxicity remains one of the most common causes of liver failure and is treated with a course of n-acetylcysteine (NAC). This exceptionally effective medication is traditionally administered using a complicated three-bag protocol that is prone to administration errors. OBJECTIVE: We aimed to assess whether switching to a novel two-bag protocol (150 mg/kg over 1 h followed by 150 mg/kg over 20 h) reduced administration errors while not increasing liver injury or anaphylactoid reactions. METHODS: This was a retrospective chart review of hospital encounters for patients with acetaminophen toxicity, comparing outcomes before and after the change from a three-bag protocol to a two-bag protocol at two affiliated institutions. The primary outcome was incidence of medication errors with secondary outcomes including acute liver injury (ALI) and incidence of non-anaphylactoid allergic reactions (NAAR). The study was approved by the health system's Institutional Review Board. RESULTS: 483 encounters were included for analysis (239 in the three-bag and 244 in the two-bag groups). NAAR were identified in 11 patients with no difference seen between groups. Similarly, no differences were seen in ALI. Medication administration errors were observed significantly less often in the two-bag group (OR 0.24) after adjusting for confounders. CONCLUSION: Transitioning to a novel two-bag NAC regimen decreased administration errors. This adds to the literature that two-bag NAC regimens are not only safe but also may have significant benefits over the traditional NAC protocol.

Polypharmacy and high-alert medications in patients with nasally placed feeding tube on admission and at hospital discharge: Multicenter cross-sectional study.

Background: Polypharmacy and the use of high-alert medications in patients with nasally placed feeding tube (NPFT) increase the risks of drug related problems. Objective: Characterize drugs prescribed to patients with NPFT and compare the rates of polypharmacy and high-alert medication use at admission and hospital discharge. Design and setting: Multicenter cross-sectional study with 327 participants. Methods: Data of patients with NPFT were obtained from the medical records and recorded in an electronic data collection tool. Mean number of drugs, polypharmacy and number of high-alert medications prescribed on admission and at discharge were compared using Wilcoxon or McNemar's tests. Generalized Estimating Equations analyzed the relationship between polypharmacy and high-alert medications according to age and time point. Primary reason for hospital admission, level of consciousness, severity of comorbid diseases and patient care complexity were also assessed. Results: Most patients were male, older people, hospitalized for circulatory system diseases and had at least one comorbidity. On admission, a significant number of patients were alert (59.9%), at high risk for death (43.1%) and high dependent on nursing care (35.4%). Additionally, 92% patients were on polypharmacy on admission, versus 84.7% at hospital discharge (p = 0,0011). The occurrence of polypharmacy was independent of age (p = 0.2377). >17% of all drugs prescribed were high-alert medications, with no statistically significant difference between admission and discharge (p = 0,3957). There was no statistical evidence that the use of high-alert medications increases with age (n = 0,5426). Conclusions: These results support the planning of multidisciplinary qualified actions for patients using NPFT.

Predisposing Factors to Medication Errors by Nurses and Prevention Strategies: A Scoping Review of Recent Literature.

Medication errors have serious consequences and high costs for the patient and the system. The treatment process and the care required for critically ill patients are complex, and these patients are more vulnerable to errors and potential consequences. A scoping review using the JBI methodology was conducted across PubMed, CINAHL, and MEDLINE databases and reported by the PRISMA-ScR guidelines to explore strategies that can mitigate medication errors by nurses. The search strategy focused on references published between January 2012 and April 2023. Sixteen studies were included, and the results were organized into thematic areas. Medication errors by nurses are in the areas of preparation, administration, and documentation; organizational, system-related, procedural, personal, and knowledge and training factors are predisposing factors for errors; educational intervention, verification and safety methods, organizational changes, and error reporting are the strategic areas to mitigate medication error. The organization of the data could be different, as it depends on the reviewers' experience. Knowledge of the factors that cause medication errors and interventions to mitigate them make it possible to outline strategies to minimize their occurrence and achieve health gains. The protocol preceding this review has been registered in the Open Science Framework and published.

How intervention studies measure the effectiveness of medication safety-related clinical decision support systems in primary and long-term care: a systematic review.

BACKGROUND: Medication errors and associated adverse drug events (ADE) are a major cause of morbidity and mortality worldwide. In recent years, the prevention of medication errors has become a high priority in healthcare systems. In order to improve medication safety, computerized Clinical Decision Support Systems (CDSS) are increasingly being integrated into the medication process. Accordingly, a growing number of studies have investigated the medication safety-related effectiveness of CDSS. However, the outcome measures used are heterogeneous, leading to unclear evidence. The primary aim of this study is to summarize and categorize the outcomes used in interventional studies evaluating the effects of CDSS on medication safety in primary and long-term care. METHODS: We systematically searched PubMed, Embase, CINAHL, and Cochrane Library for interventional studies evaluating the effects of CDSS targeting medication safety and patient-related outcomes. We extracted methodological characteristics, outcomes and empirical findings from the included studies. Outcomes were assigned to three main categories: process-related, harm-related, and cost-related. Risk of bias was assessed using the Evidence Project risk of bias tool. RESULTS: Thirty-two studies met the inclusion criteria. Almost all studies (n = 31) used process-related outcomes, followed by harm-related outcomes (n = 11). Only three studies used cost-related outcomes. Most studies used outcomes from only one category and no study used outcomes from all three categories. The definition and operationalization of outcomes varied widely between the included studies, even within outcome categories. Overall, evidence on CDSS effectiveness was mixed. A significant intervention effect was demonstrated by nine of fifteen studies with process-related primary outcomes (60%) but only one out of five studies with harm-related primary outcomes (20%). The included studies faced a number of methodological problems that limit the comparability and generalizability of their results. CONCLUSIONS: Evidence on the effectiveness of CDSS is currently inconclusive due in part to inconsistent outcome definitions and methodological problems in the literature. Additional high-quality studies are therefore needed to provide a comprehensive account of CDSS effectiveness. These studies should follow established methodological guidelines and recommendations and use a comprehensive set of harm-, process- and cost-related outcomes with agreed-upon and consistent definitions.

Unveiling the factors influencing public knowledge and behaviours towards medication errors in Jordan: a cross-sectional study.

BACKGROUND: Medication errors are preventable incidents resulting from improper use of drugs that may cause harm to patients. They thus endanger patient safety and offer a challenge to the efficiency and efficacy of the healthcare system. Both healthcare professionals and patients may commit medication errors. METHODS AND OBJECTIVES: A cross-sectional, observational study was designed using a self-developed, self-administered online questionnaire. A sample was collected using convenience sampling followed by snowball sampling. Adult participants from the general population were recruited regardless of age, gender, area of residence, medical history, or educational background in order to explore their practice, experience, knowledge, and fear of medication error, and their understanding of this drug-related problem. RESULTS: Of the 764 participants who agreed to complete the questionnaire, 511 (66.9%) were females and 295 (38.6%) had a medical background. One-fifth of participants had experienced medication errors, with 37.7% of this segment reporting these medication errors. More than half of all medication errors (84, 57.5%) were minor and thus did not require any intervention. The average anxiety score for all attributes was 21.2 (The highest possible mean was 36, and the lowest possible was 0). The highest level of anxiety was seen regarding the risk of experiencing drug-drug interactions and the lowest levels were around drug costs and shortages. Being female, having no medical background, and having experience with medication errors were the main predictors of high anxiety scores. Most participants (between 67% and 92%) were able to recognise medication errors committed by doctors or pharmacists. However, only 21.2 to 27.5% of participants could recognise medication errors committed by patients. Having a medical background was the strongest predictor of knowledge in this study (P < 0.001). CONCLUSION: The study revealed that the prevalence of self-reported medication errors was significantly high in Jordan, some of which resulted in serious outcomes such as lasting impairment, though most were minor. Raising awareness about medication errors and implementing preventive measures is thus critical, and further collaboration between healthcare providers and policymakers is essential to educate patients and establish effective safety protocols.

Factors Influencing Novice and Beginner Nurses' Intention to Report Medication Errors and Near Misses.

INTRODUCTION: Novice and beginner nurses make more medical errors than senior nurses. However, there is significant underreporting of medication errors and near misses among novice and beginner nurses. OBJECTIVE: To identify the factors that influence the intention of novice and beginner nurses to report medication errors and near misses. METHODS: A cross-sectional exploratory study was carried out among third-year nursing students in a Quebec university (n = 143). Data was collected through a self-reported questionnaire based on the adapted Theory of Planned Behavior. Simple descriptive analyses and a series of contingency analyses were performed using Chi-2 or Fisher exact tests. Correction of multiple tests was done using Bonferroni test. RESULTS: All theoretical constructs were significantly associated with intention. Sociodemographic factors (age, sex, experience and education program) were also associated with intention. DISCUSSION AND CONCLUSION: Further studies are needed to identify the determinants of intention to report medication errors and near misses among novice and beginner nurses. More attention is required in nursing practice and education to act on these factors, thus encouraging novice and beginner nurses to report medication errors and near misses.

The pharmacists' interventions after a Drug and Therapeutics Committee (DTC) establishment during the COVID-19 pandemic.

Introduction: Healthcare systems in developing countries faced significant challenges during COVID-19, grappling with limited resources and staffing shortages. Assessment of the impact of pharmaceutical care expertise, particularly in critical care units during the pandemics, in developing countries remains poorly explored. The principal aim of our study was to assess the impact of the Drug and Therapeutics Committee (DTC), comprising clinical pharmacists, on the incidence, types, and severity of medication errors and associated costs in using COVID-19 medications, especially antibiotics. Methods: An interventional pre-post study was carried out at a public isolation hospital in Egypt over 6 months. Results: Out of 499 medication orders, 238 (47.7%) had medication errors, averaging 2.38 errors per patient. The most frequent were prescribing errors (44.9%), specifically incorrect drug choice (57.9%), excessive dosage (29.9%), treatment duplication (4.5%), inadequate dosage (4.5%), and overlooked indications (3.6%). Linezolid and Remdesivir were the most common medications associated with prescribing errors. Pharmacists intervened 315 times, primarily discontinuing medications, reducing doses, introducing new medications, and increasing doses. These actions led to statistically significant cost reductions (p < 0.05) and better clinical outcomes; improved oxygen saturation, decreased fever, stabilised respiratory rates, and normalised white blood cell counts. So, clinical pharmacist interventions made a notable clinical and economic difference (66.34% reduction of the expenses) in antibiotics usage specifically and other medications used in COVID-19 management during the pandemic. Conclusion: Crucially, educational initiatives targeting clinical pharmacists can foster judicious prescribing habits.

Events related to medication errors and related factors involving nurses' behavior to reduce medication errors in Japan: a Bayesian network modeling-based factor analysis and scenario analysis.

PURPOSE: This study aimed to identify the relationships between medication errors and the factors affecting nurses' knowledge and behavior in Japan using Bayesian network modeling. It also aimed to identify important factors through scenario analysis with consideration of nursing students' and nurses' education regarding patient safety and medications. METHODS: We used mixed methods. First, error events related to medications and related factors were qualitatively extracted from 119 actual incident reports in 2022 from the database of the Japan Council for Quality Health Care. These events and factors were then quantitatively evaluated in a flow model using Bayesian network, and a scenario analysis was conducted to estimate the posterior probabilities of events when the prior probabilities of some factors were 0%. RESULTS: There were 10 types of events related to medication errors. A 5-layer flow model was created using Bayesian network analysis. The scenario analysis revealed that "failure to confirm the 5 rights," "unfamiliarity with operations of medications," "insufficient knowledge of medications," and "assumptions and forgetfulness" were factors that were significantly associated with the occurrence of medical errors. Conclusion: This study provided an estimate of the effects of mitigating nurses' behavioral factors that trigger medication errors. The flow model itself can also be used as an educational tool to reflect on behavior when incidents occur. It is expected that patient safety education will be recognized as a major element of nursing education worldwide and that an integrated curriculum will be developed.
