Calculating the cost of medication errors: A systematic review of approaches and cost variables.

INTRODUCTION: Medication errors are an unnecessary cost to a healthcare system and patients of a country. This review aimed to systematically identify published cost variables used to calculate the cost of medication errors and to explore any updates on findings already known on calculating the cost of medication errors during the past 10 years. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Electronic databases, PubMed, Scopus, Emerald and JSTOR were searched, using keywords "medication error" AND "cost" and predetermined inclusion criteria. Duplicate articles were removed. Quality check was done using 10 criteria. Cost variables used in calculating the cost of medication errors were extracted from each article. RESULTS: Among 3088 articles, 33 articles were selected for review. Most studies were conducted in Western countries. Cost variables used (types and number) by different studies varied widely. Most studies (N=29) had used direct costs only. A few studies (N=4) had used both direct and indirect costs for the purpose. Perspectives considered when calculating cost of medication errors also varied widely. A total of 35 variables used to calculate medication error costs were extracted from selected articles. CONCLUSION: Variables used to calculate the cost of medication errors were not uniform across studies. Almost a decade after systematic reviews previously reporting on this area, a validated methodology to calculate the cost of medication errors has still not been reported to date and highlights the still pending necessity of a standard method to be established.

Retraining transplant pharmacy staff to reduce Medicare Part B prescription billing errors post-transplant.

BACKGROUND: Medicare Part B (MedB) imposes penalties for certain errors in prescription billing of post-transplant medications, which can greatly affect pharmacy revenue. To prevent MedB billing fines, pharmacy staff must be cognizant of specific MedB requirements. OBJECTIVE: This quality improvement project aimed to retrain certified pharmacy technicians (CPhTs) on common billing errors and evaluate changes in error rates and potential fines after retraining. We aimed to determine whether retraining CPhTs minimizes MedB prescription billing errors and reduces potential fines owed by the Vanderbilt Transplant Pharmacy (VTP) to the Centers for Medicare and Medicaid Services (CMS). METHODS: This was a single-center, quality improvement study including post-transplant patients with at least one MedB prescription billing error who filled prescriptions through VTP. All CPhTs involved in MedB prescription billing received retraining focused on the top 3 errors in MedB billing identified at VTP: early refills, missing relationship of caller to patient and residence of patient on order documentation, or no day supply remaining recorded on the order file. Retraining consisted of developing a training checklist, testing current knowledge levels, individualized nonpunitive coaching based on technician specific errors, and retesting for knowledge retention. Outcomes included the number of prescriptions with at least one MedB prescription billing error and the projected amount of dollars fined owing to errors recorded during the 3 months before and 3 months after retraining. RESULTS: Fourteen CPhTs received retraining. Average refill too soon errors decreased by 37.5% (10.7% vs. 6.7%), average missing relationship by 21.7% (7.7% vs. 6%), and day supply errors by 39.7% (1.7% vs. 1%). Error reductions equaled a 28.2% decrease (approximately $12,700) in potential fines. CONCLUSION: Retraining focused on MedB billing error successfully reduced error frequency and fines from CMS. MedB billing error fines can be costly for pharmacies dispensing high-cost medications; therefore, identifying common errors and training staff can be useful and financially prudent.

An Analysis of Incident Reports Related to Electronic Medication Management: How They Change Over Time.

OBJECTIVE: Electronic medication management (EMM) systems have been shown to introduce new patient safety risks that were not possible, or unlikely to occur, with the use of paper charts. Our aim was to examine the factors that contribute to EMM-related incidents and how these incidents change over time with ongoing EMM use. METHODS: Incidents reported at 3 hospitals between January 1, 2010, and December 31, 2019, were extracted using a keyword search and then screened to identify EMM-related reports. Data contained in EMM-related incident reports were then classified as unsafe acts made by users and the latent conditions contributing to each incident. RESULTS: In our sample, 444 incident reports were determined to be EMM related. Commission errors were the most frequent unsafe act reported by users (n = 298), whereas workarounds were reported in only 13 reports. User latent conditions (n = 207) were described in the highest number of incident reports, followed by conditions related to the organization (n = 200) and EMM design (n = 184). Over time, user unfamiliarity with the system remained a key contributor to reported incidents. Although fewer articles to electronic transfer errors were reported over time, incident reports related to the transfer of information between different computerized systems increased as hospitals adopted more clinical information systems. CONCLUSIONS: Electronic medication management-related incidents continue to occur years after EMM implementation and are driven by design, user, and organizational conditions. Although factors contribute to reported incidents in varying degrees over time, some factors are persistent and highlight the importance of continuously improving the EMM system and its use.

Improving Patient Safety in Medication Management by Medication Reconciliation and Pharmaceutical Care Process in Post-Liver Transplant Clinic.

INTRODUCTION: Liver transplant recipients receive many medications for anti-rejection, infection prophylaxis, and treatment of comorbidities. Most of them also receive medications from multiple sources. Therefore, these patients are prone to drug-related problems (DRPs) and medication errors. This study aimed to study the effect of medication reconciliation (MR) and pharmaceutical care processes by transplant pharmacists in the post-liver transplant clinic. METHODS: This study was a retrospective study in Siriraj Liver Transplant Center, Mahidol University, Thailand. Patients who received pharmaceutical care from transplant pharmacists were compared before and after the implementation of MR (October 2020-September 2021 vs October 2021-September 2022) to assess the prevalence of medication errors and identify DRPs between the 2 groups. RESULTS: Before implementation of MR, in a total of 797 visits, 69 medication errors (8.7%) were found. The most errors were medication omissions (44.9%, n = 31). After the implementation of MR, in a total of 879 visits, 44 medication errors (5.0%) were found. Most were medication omission and incorrect strength (31.8%, n = 14). Medication errors significantly decreased by 36.2% (P < .001) after the implementation of MR. Regarding DRPs, transplant pharmacists could significantly detect more DRPs after implementation of MR, 66 DRPs before implementation of MR vs 111 DRPs after implementation of MR (P < .001). The most DRPs were non-adherence (34 vs 41). CONCLUSIONS: MR can reduce medication errors and assist transplant pharmacists in identifying DRPs that will lead to active intervention by attending physicians and/or patients to improve medication management and patient safety in post-liver transplant care.

Advanced prescription of injectable anticancer drugs: Safety assessment in a European Comprehensive Cancer Centre using the risk matrix approach.

AIMS: The purpose of this work was to assess failures in the advanced prescription of parenteral anticancer agents in an adult day oncology care unit with more than 100 patients per day. METHODS: An a priori descriptive analysis was carried out by using the risk matrix approach. After defining the scope in a multidisciplinary meeting, we determined at each step the failure modes (FMs), their effects (E) and their associated causes (C). A severity score (S) was assigned to all effects and a probability of occurrence (O) to all causes. These S and O indicators, were used to obtain a criticality index (CI) matrix. We assessed the risk control (RC) of each failure in order to define a residual criticality index (rCI) matrix. RESULTS: During risk analysis, 14 FMs were detected, and 61 scenarios were identified considering all possible effects and causes. Nine situations (15%) were highlighted with the maximum CI, 18 (30%) with a medium CI, and 34 (55%) with a negligible CI. Nevertheless, among all these critical situations, only three (5%) had an rCI to process (i.e., missed dose adjustment, multiple prescriptions and abnormal biology data); the others required monitoring only. Clinicians' and pharmacists' knowledge of these critical situations enables them to manage the associated risks. CONCLUSIONS: Advanced prescription of injectable anticancer drugs appears to be a safe practice for patients when combined with risk management. The major risks identified concerned missed dose adjustment, prescription duplication and lack of consideration for abnormal biology data.

Exploring the Role of Guidelines in Contributing to Medication Errors: A Descriptive Analysis of National Patient Safety Incident Data.

INTRODUCTION: Clinical guidelines can contribute to medication errors but there is no overall understanding of how and where these occur. OBJECTIVES: We aimed to identify guideline-related medication errors reported via a national incident reporting system, and describe types of error, stages of medication use, guidelines, drugs, specialties and clinical locations most commonly associated with such errors. METHODS: Retrospective analysis of reports to the National Reporting and Learning System for England and Wales. A hierarchical task analysis (HTA) was developed, describing expected practice when using guidelines. A free-text search was conducted of medication incident reports (2016-2021) using search terms related to common guidelines. All identified reports linked to moderate-severe harm or death, and a random sample of 5100 no/low-harm reports were coded to describe deviations from the HTA. A random sample of 500 cases were independently double-coded. RESULTS: In total, 28,217 reports were identified, with 608 relating to moderate-severe harm or death. Fleiss' kappa for interrater reliability was 0.46. Of the 5708 reports coded, 642 described an HTA step discrepancy (including four linked to a death), suggesting over 3200 discrepancies in the entire dataset of 28,217 reports. Discrepancies related to finding guidelines (n = 300 reports), finding information within guidelines (n = 166) and using information (n = 176). Discrepancies were most frequently identified for guidelines produced by a local organisation (n = 405), and most occurred during prescribing (n = 277) or medication administration (n = 241). CONCLUSION: Difficulties finding and using information from clinical guidelines contribute to thousands of prescribing and medication administration incidents, some of which are associated with substantial patient harm.

Assessment of medication discrepancy, medication appropriateness, and cost analysis among patients with pediatric nephrotic syndrome: An ambispective cohort observational study.

BACKGROUND: Nephrotic syndrome (NS) is a commonly encountered chronic kidney disease in pediatric populations, with South Asian children being at high risk and requiring long-term pharmacological management. Thus, identifying medication discrepancies and evaluating the appropriateness of therapy and its economic burden are vital for inpatient management. The aim of the study was to assess medication reconciliation, medication appropriateness, and cost analysis in NS cases. METHODS: An ambispective cohort observational study was carried out with 150 NS patients where medication discrepancies were identified retrospectively and prospectively using the best possible medication history and following up patients correspondingly. Further, the Medication Appropriateness Index and cost variation analysis were used to assess the prescribed therapy and cost analysis, respectively. RESULTS: Out of 150 patients with NS included, 67.3% were male and the mean age was 7.2 years. In total, 36.7% medication discrepancies were found at baseline and 6% discrepancies at follow-up. The majority of discrepancies were unintentional and due to dosing error both at baseline and follow-up. Further, in only 2% of the patients was there inappropriately prescribed medication, and the majority of patients spent between INR (Indian Rupees) 500 and 1000. CONCLUSION: Chronic conditions like NS require continuous monitoring by the specialist pediatric clinical pharmacist, who can contribute significantly by minimizing the medication discrepancies, by assessing the appropriateness of therapy, and lessening the economic burden.

Flow of information contributing to medication incidents in home care-An analysis considering incident reporters' perspectives.

AIM: To describe the contributing factors and types of reported medication incidents in home care related to the flow of information in different phases of the medication process, as reported by multi-professional healthcare groups. DESIGN: This descriptive, qualitative study used retrospective data. METHODS: An incident-reporting database was used to collect 14,289 incident reports from 2017 to 2019 in a city in Finland. We used this data to select medication incidents (n = 1027) related to the flow of information in home care and between home care and hospitals. Data were divided into five groups based on the medication phase: (1) prescribing, (2) dispensing, (3) administration, (4) documentation and (5) self-administration. In addition, the types of medication-related incidents were described. The data were examined using abductive content analysis. The EQUATOR SRQR checklist was used in this report. RESULTS: Four main categories were identified from the data: (1) issues related to information management, (2) cooperation issues between different actors, (3) work environment and lack of resources and (4) factors related to healthcare workers. Cooperation issues contributed to medication-related incidents during each phase. Incomplete communication was a contributing factor to medication incidents. This occurred between home care, remote care, hospital, the client and the client's relatives. Specifically, a lack of information-sharing occurred in repatriation situations, where care transitioned between different healthcare professionals. CONCLUSION: Healthcare professionals, organisations, clients and their relatives should focus on the efficient and safe acquisition of medications. Specifically, the use of electronic communication systems, together with oral reports and checklists for discharge situations, and timely cooperation with pharmacists should be developed to manage information flows. RELEVANCE TO CLINICAL PRACTICE: These findings demonstrate that healthcare professionals require uniform models and strategies to accurately and safely prescribe, dispense and administer medications in home care settings. No patient or public contributions.

Clinical impact and cost-saving analysis of a comprehensive pharmaceutical care intervention in older patients with cancer.

BACKGROUND: Hospital admission and discharge are at high risk of drug-related problems (DRPs) in older patients with cancer. This study aimed to assess the clinical and economic impact of a comprehensive pharmaceutical care intervention (RECAP) to optimize drug therapy in patients with cancer ≥75 years admitted to oncology or geriatric wards. METHOD: RECAP intervention was defined as follows: at admission and discharge, hospital pharmacists conducted comprehensive medication reconciliation and review, identified relevant DRPs and provided optimization recommendations to prescribers; at discharge, pharmacists also provided patient education and shared information with primary care providers. The impact of the intervention was assessed by the rate of implementation of recommendations by the prescribers and the evolution of polypharmacy rate; a peer review of the clinical significance of DRPs was performed by an expert panel of geriatric oncologists and pharmacists. A cost saving analysis compared cost avoided through resolution of DRPs to cost of pharmacist's time. RESULTS: From January 2019 and August 2020, 201 patients were included (median age 80 [75-97] years), 68.7% with solid tumors. DRPs requiring optimization were identified in 70.9% of patients at admission (mean 1.7 DRP/patient) and 47.7% at discharge (0.9 DRP/patient). Most pharmacist recommendations (70.8%) were followed by prescribers, allowing the correction of 1.2 DRP/patient at admission and 0.7 DRP/patient at discharge. Half of resolved DRPs were rated as clinically significant. However, polypharmacy rate was not reduced at discharge. Cost comparison showed $7.2 avoided for $1 invested, with an estimated total net benefit of $354,822 (mean $1766 per patient). CONCLUSIONS: The RECAP model significantly reduces DRPs in hospitalized older patients with cancer. The model was cost saving, confirming the value of implementing it in routine practice.

Estimated Costs of Drug-Related Problems Prevented by Pharmacist Prescription Reviews Among Hospitalized Internal Medicine Patients.

BACKGROUND AND OBJECTIVES: Data are lacking on the estimated costs of pharmacist prescription reviews (PPRs) for hospitalized internal medicine patients. This study investigates the estimated costs of drug-related problems (DRPs) prevented by PPRs among hospitalized internal medicine patients. METHODS: We reviewed all medication orders for patients at an academic teaching hospital in China for 2 years. DRPs were categorized using the Pharmaceutical Care Network Europe classification. The severity of the potential harm of DRPs was assessed by the Harm Associated with Medication Error Classification (HAMEC) tool. The estimated cost of PPRs was calculated. RESULTS: A total of 162426 medication orders for 4314 patients were reviewed, and 1338 DRPs were identified by pharmacists who spent 2230 hours performing PPRs. Among the 1080 DRPs that were prospectively intervened upon, 703 were resolved. The HAMEC tool showed that 47.1% of DRPs were assessed as level 2, 30.4% as level 3, 20.6% as level 1, and 0.6% carried a life-threatening risk. Pharmacist interventions contributed to the prevention of DRP errors and a reduction of $339 139.44. This resulted in a mean cost saving of $482.42 per patient at an input cost of $21 495.06 over the 2 years. The benefit-cost ratio was 15.8. CONCLUSION: PPRs are beneficial for detecting potential DRPs and creating potential cost savings among hospitalized internal medicine patients.

Medication Safety Event Reporting: Factors That Contribute to Safety Events During Times of Organizational Stress.

BACKGROUND: Incident reports submitted during times of organizational stress may reveal unique insights. PURPOSE: To understand the insights conveyed in hospital incident reports about how work system factors affected medication safety during a coronavirus disease-2019 (COVID-19) surge. METHODS: We randomly selected 100 medication safety incident reports from an academic medical center (December 2020 to January 2021), identified near misses and errors, and classified contributing work system factors using the Human Factors Analysis and Classification System-Healthcare. RESULTS: Among 35 near misses/errors, incident reports described contributing factors (mean 1.3/report) involving skill-based errors (n = 20), communication (n = 8), and tools/technology (n = 4). Reporters linked 7 events to COVID-19. CONCLUSIONS: Skill-based errors were the most common contributing factors for medication safety events during a COVID-19 surge. Reporters rarely deemed events to be related to COVID-19, despite the tremendous strain of the surge on nurses. Future efforts to improve the utility of incident reports should emphasize the importance of describing work system factors.

Nurses' perception of medication administration errors and factors associated with their reporting in the neonatal intensive care unit.

Medication administration is a complex process, and nurses play a central role in this process. Errors during administration are associated with severe patient harm and significant economic burden. However, the prevalence of under-reporting makes it challenging when analysing the current landscape of medication administration error (MAE) and hinders the implementation of improvements to the existing system. The aim of this study is to describe the reasons for the occurrence of MAEs and the reasons behind the under-reporting of MAEs, to determine the estimated percentage of MAE reporting and to identify factors associated with them from the nurses' perspective. This cross-sectional study was conducted using a validated self-administered questionnaire. The questionnaire contained 65 questions which were divided into three sections: (i) reasons for the occurrence of MAEs, which consisted of 29 items; (ii) reasons for not reporting MAEs, which consisted of 16 items; and (iii) percentage of MAEs actually reported, which consisted of 20 items. It was distributed to 143 nurses in the neonatal intensive care units of five public hospitals in Malaysia. Multivariable logistic regression was used to identify the factors associated with MAE reporting. The estimated percentage of MAE reporting was 30.6%. The most common reasons for MAEs were inadequate nursing staff (5.14 [SD 1.25]), followed by drugs which look alike (4.65 [SD 1.06]) and similar drug packaging (4.41 [SD 1.18]). The most common reasons for not reporting MAEs were that nursing administration focuses on the individual rather than looking at the systems as a potential cause of the error (4.56 [SD 1.32]) and that too much emphasis is placed on MAEs as a measure of the quality of nursing care (4.31 [SD 1.23]). Factors statistically significant with MAE reporting were administration response (adjusted odds ratio [AOR] = 6.90; 95% confidence interval (CI) = 2.01-23.67; P = 0.002), reporting effort (AOR = 3.67; 95% CI = 1.68-8.01; P = 0.001), and nurses with advanced diploma (AOR = 0.29; 95% CI = 0.13-0.65; P = 0.003). Our findings show that under-reporting of MAEs is still common and less than a third of the respondents reported MAEs. Therefore, to encourage error reporting, emphasis should be placed on the benefits of reporting, adopting a non-punitive approach, and creating a blame-free culture.

Measurement of Ambulatory Medication Errors in Children: A Scoping Review.

BACKGROUND AND OBJECTIVES: Children use most medications in the ambulatory setting where errors are infrequently intercepted. There is currently no established measure set for ambulatory pediatric medication errors. We have sought to identify the range of existing measures of ambulatory pediatric medication errors, describe the data sources for error measurement, and describe their reliability. METHODS: We performed a scoping review of the literature published since 1986 using PubMed, CINAHL, PsycINFO, Web of Science, Embase, and Cochrane and of grey literature. Studies were included if they measured ambulatory, including home, medication errors in children 0 to 26 years. Measures were grouped by phase of the medication use pathway and thematically by measure type. RESULTS: We included 138 published studies and 4 studies from the grey literature and identified 21 measures of medication errors along the medication use pathway. Most measures addressed errors in medication prescribing (n = 6), and administration at home (n = 4), often using prescription-level data and observation, respectively. Measures assessing errors at multiple phases of the medication use pathway (n = 3) frequently used error reporting databases and prospective measurement through direct in-home observation. We identified few measures of dispensing and monitoring errors. Only 31 studies used measurement methods that included an assessment of reliability. CONCLUSIONS: Although most available, reliable measures are too resource and time-intensive to assess errors at the health system or population level, we were able to identify some measures that may be adopted for continuous measurement and quality improvement.

An Observational Study to Identify Drug-related Problems (DRP) in Routine Care and An Expert Panel Assessment to Rate Clinical Risk and Preventability by Unit-dose Dispensing Systems (UDDS) with Computerized Physician Order Entry (CPOE) and Clinical Decision-Support Systems (CDSS).

Background and aim: Drug-related problems (DRP) jeopardize patient safety. Unit-dose dispensing systems (UDDS) with computerized-physician-order-entry (CPOE) and clinical-decision-support-systems (CDSS) were reported as a promising concept for preventing DRP. We aimed at identifying and categorizing DRP in peroral drug administration considering their clinical risk and preventability by UDSS/CPOE/CDSS. Investigations: In surgical and internal-medicine departments, we observed routine procedures in peroral drug administration for DRP. An expert panel including pharmaceutical and nursing expertise categorized the identified 18 DRP categories into three levels: DRP that have not yet resulted in medication errors (ME) (Level-I), DRP where ME have occurred but have not yet reached the patient (Level-II), and DRP where ME have occurred and have reached the patient (Level-III). Additionally, the panel categorized DRP according to their clinical risk and whether the implementation of UDSS/CPOE/CDSS can prevent them. Results: In 77 surgical patients, 1,849 peroral drug administration procedures, and in 149 internal-medicine patients, 1,405 procedures were observed. The 18 DRP categories were identified with a frequency of 0.6%-26.7% (Level-I), 0.1%-21.5% (Level-II), and 0.0%-1.0% (Level-III). Of those, four categories were considered of high clinical risk: "Name of the medication is not readable", "Prescribed medication is not prepared for administration", "An incorrect or non-prescribed medication is prepared", and "A medication is prepared for the wrong patient (mix-up)". Twelve DRP categories were categorized as highly preventable by UDSS/CPOE/CDSS. Conclusions:Under routine conditions, we identified a substantial number of DRPs. An expert panel categorized many of those DRPs as clinically highly relevant and highly preventable by UDSS/CPOE/CDSS.

Impact of the implementation of Identification-Situation-Background-Assessment-Recommendation (ISBAR) tool to improve quality and safety measure in a lithotripsy and endourological unit.

INTRODUCTION: A lack of professional communication and collaboration may be one of the main causes of medication errors. The objective was to evaluate the results of the implementation of ISBAR as a communication and safety tool in a Lithotripsy and Endourologic Unit of a tertiary public hospital. METHODS: A total of 457 patients were included in a retrospective study from 2014 to 2019. Patients were divided into two groups: group A (357 patients) in which an endourological procedure was performed before march of 2018 (without the implementation of ISBAR tool) and Group B (100 patients) with the implementation of ISBAR tool. The inclusion criteria were patients accepted for surgical intervention by anaesthesiology Department and operated in the period of the study. The variables analysed included number of procedures, global, intraoperative and postoperative complications rate, urinary infection or sepsis, NPR (FMEA), percentage of suspended surgical patients and hospital stay. RESULTS: The postoperative complications showed no significant differences between groups, but a trend to diminishing was seen in the complication in the group B. The sepsis reduced its incidence and it was close to significant difference. The operative time was shorter in group B 119,11min (114,63-123,59) vs 115,11min (109,63-121,67) p = 0,3. The reduction in the main postoperative complication (sepsis) explained the lower hospital stay for group B. The severe adverse events detected were reduced completely. CONCLUSIONS: ISBAR tool was an effective patient safety tool improving quality care. To provide safe patient care and improving quality is indispensable an effective communication flow.

Physician Burnout and Medical Errors: Exploring the Relationship, Cost, and Solutions.

Physician burnout has demonstrated risks to providers and patients through medical errors. This review aims to synthesize current data surrounding burnout and its impacts on quality to inform targeted interventions that benefit providers and patients. Preferred Reporting Items for Systematic Reviews and Meta-Analyses scoping review methodology was utilized to identify studies of quantitative metrics for burnout and medical errors. Three independent reviewers conducted screening, study selection, and data extraction. Of 1096 identified articles, 21 were analyzed. Overall, 80.9% used the Maslach Burnout Inventory to evaluate for burnout. Moreover, 71.4% used self-reported medical errors as their primary outcome measure. Other outcome measures included observed/identified clinical practice errors and medication errors. Ultimately, 14 of 21 studies found links between burnout and clinically significant errors. Significant associations exist between burnout and medical errors. Physician demographics, including psychological factors, well-being, and training level, modulate this relationship. Better metrics are necessary to quantify errors and their impacts on outcomes. These findings may inform novel interventions that target burnout and improve experiences.

Contributory factors and patient harm including deaths associated direct acting oral anticoagulants (DOACs) medication incidents: evaluation of real world data reported to the National Reporting and Learning System.

INTRODUCTION: Direct oral anticoagulants (DOACs) are considered high risk medicines and are frequently associated with medication errors. The nature of incidents and associated outcomes of such incidents are poorly understood. AREAS COVERED: Using a national patient safety reporting database, the National Reporting and Learning System (NRLS), this study aimed to report the contributory factors and outcomes including severe harm and deaths related to all safety incidents involving DOACs reported in England and Wales between 2017-2019. Reason's accident causation model was used to classify the incidents. EXPERT OPINION: A total of 15,730 incident reports were analyzed. A total of 25 deaths were reported with a further 270 and 55 incidents leading to moderate and severe harm, respectively. A further 8.8% (n = 1381) of incidents were associated with low degree of harm. The majority of the incidents involved active failures (n = 13776; 87.58) including duplication of anticoagulant therapies, patients being discharged without DOACs, non-consideration of renal function, and lack of commencement of DOACs post-surgery suggesting preventability of such reported incidents. This study shows that medication incidents involving DOACs have the potential to cause severe harm and deaths, and there is a need to promote guideline adherence through education, training, and decision support technologies.

The Additional Cost of Perioperative Medication Errors.

ABSTRACT: The purpose of this report was to estimate the additional annual cost to the U.S. healthcare system attributable to preventable medication errors (MEs) in the operating room. The ME types were iteratively grouped by their associated harm (or potential harm) into 13 categories, and we determined the incidence of operations involving each ME category (number of operations involving each category/total number of operations): (1) delayed or missed required perioperative antibiotic (1.4% of operations); (2) prolonged hemodynamic swings (7.6% of operations); (3) untreated postoperative pain >4/10 (18.9% of operations); (4) residual neuromuscular blockade (2.9% of operations); (5) oxygen saturation <90% due to ME (1.8% of operations); (6) delayed emergence (1.1% of operations); (7) untreated new onset intraoperative cardiac arrhythmia (0.72% of operations); (8) medication documentation errors (7.6% of operations); (9) syringe swaps (5.8% of operations); (10) presumed hypotension with inability to obtain a blood pressure reading (2.2% of operations); (11) potential for bacterial contamination due to expired medication syringes (8.3% of operations); (12) untreated bradycardia <40 beats/min (1.1% of operations); and (13) other (13.0% of operations). Through a PubMed search, we determined the likelihood that the ME category would result in downstream patient harm such as surgical site infection or acute kidney injury, and the additional fully allocated cost of care (in 2021 U.S. dollars) for each potential downstream patient harm event. We then estimated the cost of the MEs across the U.S. healthcare system by scaling the number of MEs to the total number of annual operations in the United States (N = 19,800,000). The total estimated additional fully allocated annual cost of care due to perioperative MEs was $5.33 billion U.S. dollars.
