Systematic review of medication errors in pediatric patients

Medication errors in emergency departments: a systematic review and meta-analysis of prevalence and severity

BACKGROUND

Medication errors significantly compromise patient safety in emergency departments. Although previous studies have investigated the prevalence of these errors in this setting, results have varied widely.

AIM

The aim was to report pooled data on the prevalence and severity of medication errors in emergency departments, as well as the proportion of patients affected by these errors.

METHOD

Systematic searches were conducted in Embase, PubMed, and the Cochrane Library from database inception until June 2023. Studies provided numerical data on medication errors within emergency departments were eligible for inclusion. Random-effects meta-analysis was employed to pool the prevalence of medication errors, the proportion of patients experiencing these errors, and the error severity levels. Heterogeneity among studies was assessed using the I2 statistic and Cochran's Q test.

RESULTS

Twenty-four studies met the inclusion criteria. The meta-analysis gave a pooled prevalence of medication errors in emergency departments of 22.6% (95% Confidence Interval [CI] 19.2-25.9%, I2 = 99.9%, p < 0.001). The estimated proportion of patients experiencing medication errors was 36.3% (95% CI 28.3-44.3%, I2 = 99.8%, p < 0.001). Of these errors, 42.6% (95% CI 5.0-80.1%) were potentially harmful but not life-threatening, while no-harm errors accounted for 57.3% (95% CI 14.1-100.0%).

CONCLUSION

The prevalence of medication errors, particularly those potentially harmful, underscores potential safety issues in emergency departments. It is imperative to develop and implement effective interventions aimed at reducing medication errors and enhancing patient safety in this setting.

Standardisation of intravenous infusion therapy for paediatrics: big challenges for the little patients

BACKGROUND

Worldwide organisations advocate standardising the management of intravenous drugs as an essential strategy to increase safety in paediatric healthcare settings. Intravenous administration is a route associated with some potential complications. Many adverse events are related to the use of intravenous medications, and the great variability in their handling and preparation represents an added risk that jeopardises the safety of children.

PURPOSE

To standardise the dilutions of intravenous drugs most commonly administered to Spanish hospitalised paediatric and neonatal patients.

METHODS

The process leading to the standardisation of concentrations was undertaken following a two-round modified Delphi procedure. The consensus included the most common drugs administered by continuous or intermittent intravenous infusion to hospitalised and/or critically ill paediatric patients.

RESULTS

For paediatric patients, the proposal included a total of 102 drugs (45 continuous infusion and 59 intermittent infusion), with 192 concentrations to be standardised. The final consensus included 101 drugs (99%), of which 44 were continuous infusion and 59 intermittent infusion; 160 concentrations were standardised (72.7%). For neonates, the initial proposal included 80 drugs (38 continuous infusion and 43 intermittent infusion), with 189 concentrations to be standardised. The final consensus included 80 drugs (100%), of which 38 were continuous infusion and 43 were intermittent infusion; 120 concentrations were standardised (49.2%).

CONCLUSIONS

This proposal showed that standardisation is a feasible approach that can be reached by other healthcare institutions. It can be used in other centres and contribute in the future to unifying paediatric clinical practice.

Decreasing Prescribing Errors in Antimicrobial Stewardship Program-Restricted Medications

OBJECTIVES

Antimicrobial stewardship programs (ASPs) restrict prescribing practices to regulate antimicrobial use, increasing the risk of prescribing errors. This quality improvement project aimed to decrease the proportion of prescribing errors in ASP-restricted medications by standardizing workflow.

METHODS

The study took place on all inpatient units at a tertiary care children's hospital between January 2020 and February 2022. Patients <22 years old with an order for an ASP-restricted medication course were included. An interprofessional team used the Model for Improvement to design interventions targeted at reducing ASP-restricted medication prescribing errors. Plan-Do-Study-Act cycles included standardizing communication and medication review, implementing protocols, and developing electronic health record safety nets. The primary outcome was the proportion of ASP-restricted medication orders with a prescribing error. The secondary outcome was time between prescribing errors. Outcomes were plotted on control charts and analyzed for special cause variation. Outcomes were monitored for a 3-month sustainability period.

RESULTS

Nine-hundred ASP-restricted medication orders were included in the baseline period (January 2020-December 2020) and 1035 orders were included in the intervention period (January 2021-February 2022). The proportion of prescribing errors decreased from 10.9% to 4.6%, and special cause variation was observed in Feb 2021. Mean time between prescribing errors increased from 2.9 days to 8.5 days. These outcomes were sustained.

CONCLUSIONS

Quality improvement methods can be used to achieve a sustained reduction in the proportion of ASP-restricted medication orders with a prescribing error throughout an entire children's hospital.

An Assessment of Medication Errors Among Pediatric Patients in Three Hospitals in Freetown Sierra Leone: Findings and Implications for a Low-Income Country

Background

Pediatric patients are prone to medicine-related problems like medication errors (MEs), which can potentially cause harm. Yet, this has not been studied in this population in Sierra Leone. Therefore, this study investigated the prevalence and nature of MEs, including potential drug-drug interactions (pDDIs), in pediatric patients.

Methods

The study was conducted in three hospitals among pediatric patients in Freetown and consisted of two phases. Phase one was a cross-sectional retrospective review of prescriptions for completeness and accuracy based on the global accuracy score against standard prescription writing guidelines. Phase two was a point prevalence inpatient chart review of MEs categorized into prescription, administration, and dispensing errors and pDDIs. Data was analyzed using frequency, percentages, median, and interquartile range. Kruskal-Wallis H and Mann-Whitney U-tests were used to compare the prescription accuracy between the hospitals, with p<0.05 considered statistically significant.

Results

Three hundred and sixty-six (366) pediatric prescriptions and 132 inpatient charts were reviewed in phases one and two of the study, respectively. In phase one, while no prescription attained the global accuracy score (GAS) gold standard of 100%, 106 (29.0%) achieved the 80-100% mark. The patient 63 (17.2%), treatment 228 (62.3%), and prescriber 33 (9.0%) identifiers achieved an overall GAS range of 80-100%. Although the total GAS was not statistically significant (p=0.065), the date (p=0.041), patient (p=<0.001), treatment (p=0.022), and prescriber (p=<0.001) identifiers were statistically significant across the different hospitals. For phase two, the prevalence of MEs was 74 (56.1%), while that of pDDIs was 54 (40.9%). There was a statistically positive correlation between the occurrence of pDDI and number of medicines prescribed (r=0.211, P=0.015).

Conclusion

A Low GAS indicates poor compliance with prescription writing guidelines and high prescription errors. Medication errors were observed at each phase of the medication use cycle, while clinically significant pDDIs were also reported. Thus, there is a need for training on prescription writing guidelines and medication errors.

Root cause analysis of medication errors of the most frequently involved active substances in paediatric patients

BACKGROUND

Use of medicinal products in paediatric patients is identified as a risk factor for the occurrence of medication errors.

OBJECTIVES

To describe and identify root causes of medication errors in children and adolescents spontaneously reported to Agency for Medicinal Products and Medical Devices of Croatia (Agency).

METHOD

Agency's adverse drug reaction database was searched by using the Standardised MedDRA Query: medication errors (Broad) with data lock point set at 30th June 2022. Cases in which medication errors occurred in patients up to 18 years of age were analysed according to the patients' age group and gender, reporter's qualification, seriousness, reported preferred terms and active substances. For the first 30 most frequently reported active substances, an in-depth analysis was performed to identify the root cause of medication errors.

RESULTS

Altogether, 6254 reports were spontaneously reported to the Agency, out of which 1947 (31 %) contained at least one preferred term belonging to Standardised MedDRA Query medication errors. More than half of patients experiencing medication errors belonged to the age group 2-11 years (66 %) and male gender (53 %). The most frequently reported ME PTs included accidental exposure to product by a child (64 %) and accidental overdose (17 %). Medication error root causes for the first 30 most frequently involved active substances included misinterpretation of prescribed dosage due to a very small volume resulting in salbutamol overdose; replacing millilitre and milligram units resulting in paracetamol solution overdose; interchange between medicinal products due to primary package similarities resulting in cholecalciferol overdose and interchange between oral solution and syrup resulting in valproate overdose.

CONCLUSIONS

Healthcare professionals should counsel caregivers about the importance of keeping medicinal products out of children's reach and provide detailed instructions on how to appropriately use medicinal products.

Small patients, big challenges: navigating pediatric drug manipulations to prevent medication errors - a comprehensive review

INTRODUCTION

Medication errors during drug manipulations in pediatric care pose significant challenges to patient safety and optimal medication management. Epidemiological studies have revealed a high prevalenceof medication errors throughout the medication process. Due to the lack of age-appropriate dosage forms, medication manipulation is common in pediatric drug administration. The consequences of these manipulations on drug efficacy and safety could be devastating, highlighting the need for evidence-based guidelines and standardized compounding practices.

AREAS COVERED

This review focuses on examining medication errors in pediatric care and delving into the manipulation of medicinal products.

EXPERT OPINION

The observed prevalence of medication errors and manipulations underscores the importance of addressing these issues to enhance patient safety and improve medication outcomes in pediatric care. Overall, the development of age-appropriate formulations and the dissemination of comprehensive clinical guidelines are essential steps toward improving medication safety and minimizing manipulations in pediatric healthcare settings.

Reducing Medication Errors in Children's Hospitals

OBJECTIVES

Knowledge of the prevalence and characteristics of medication errors in pediatric and neonatal patients is limited. This study aimed to evaluate the incidence and medication error characteristics in a pediatric hospital over 5 years and to determine whether serial error prevention programs to optimize a computerized physician order entry (CPOE) system reduce error incidence.

METHODS

We retrospectively reviewed medication errors documented between January 2015 and December 2019.

RESULTS

A total of 2,591,596 prescriptions were checked, and 255 errors were identified. Wrong dose prescriptions constituted the most common errors (56.9%). Medications with the highest rate of errors were antibiotics/antiviral drugs (36.9%). Oral route medications comprised the highest portion (60.8%), followed by intravenous ones (28.6%). The most common stage for medication errors was physician ordering (93.3%). Junior residents were responsible for most errors (45.9%). Most errors occurred in the pediatric ward (53.7%). In total, 221 (86.7%) errors were near misses. Only 4 errors (1.6%) were considered significant and required active monitoring or intervention. Type of error, stage of error, staff composition, and severity level of errors were significantly related to the number of errors in different years. There was a statistically significant decrease in errors per 100,000 prescriptions across different years after optimizing the CPOE system.

CONCLUSIONS

The incidence of medication errors decreased with extensive use of the CPOE system. Continuous application of the CPOE optimization program can effectively reduce medication errors. Further incorporation of pediatric-specific decision-making and support tools and error prevention measures into CPOE systems is needed.

For children admitted to hospital, what interventions improve medication safety on ward rounds? A systematic review

OBJECTIVE

Every year, medication errors harm children in hospitals. Ward rounds are a unique opportunity to bring information together and plan management. There is a need to understand what strategies can improve medication safety on ward rounds. We systematically reviewed published interventions to improve prescribing and safety of medicines on ward rounds.

DESIGN

Systematic review of randomised controlled trials and observational studies.

SETTING

Studies examining inpatient ward rounds.

PATIENTS

Children and young people aged between 0 and 18 years old.

INTERVENTIONS

Any intervention or combination of interventions implemented that alters how paediatric ward rounds review inpatient medications.

MAIN OUTCOME MEASURE

Primary outcome was improvement in medication safety on paediatric ward rounds. This included reduction in prescribing error rates, healthcare professionals' opinions on prescribing and improvement in documentation on ward rounds.

RESULTS

Three studies were eligible for review. One examined the use of an acrostic, one the use of a checklist, and the other a use of a specific prescribing ward round involving a clinical pharmacist and doctor. None of the papers considered weight-based errors or demonstrated reductions in clinical harm. Reductions in prescribing errors were noted by the different interventions.

CONCLUSIONS

There are limited data on interventions to improve medication safety in paediatric ward rounds, with all published data being small scale, either quality improvement or audits, and locally derived/delivered. Good-quality interventional or robust quality improvement studies are required to improve medication safety on ward rounds.

Medication Errors in Pediatric Patients after Implementation of a Field Guide with Volume-Based Dosing

BACKGROUND

Several studies have demonstrated the high frequency of medication errors in pediatric patients by prehospital providers during both patient care and simulation. In 2015, our hospital-based urban EMS system introduced the Handtevy^TM Field Guide that provides precalculated pediatric doses in milliliters (mL) by patient age. We hypothesized that implementation of the Field Guide would increase the percentage of correct pediatric medication doses to greater than 85%.

METHODS

We performed a single center retrospective cohort study of medications administered to patients < 13 years of age from August 2017 to July 2019 compared to 2014 baseline data through electronic medical record review. We excluded nebulized medications and online medication direction cases. Our primary outcome was the percentage of correct doses defined as a dose within 80-120% of the Field Guide dose recommendation. Each dosing error was reviewed by two investigators.

RESULTS

We analyzed 483 drug administrations in 375 patients for the Field Guide study period. Doses were correct in 89.4% of medication administrations with 68.5% reportedly administered exactly as dictated by the Field Guide compared to 51.1% in the baseline period (p < 0.001). During the Field Guide study period, the following medications had 100% appropriate dosing: adenosine, dextrose 10%, diphenhydramine, epinephrine 1:10,000, glucagon, naloxone and oral ondansetron. Overdoses accounted for 4.4% of medication errors and underdoses accounted for 6.2% of medications errors. The most overdosed medications were intranasal (IN) midazolam (11.8%) and intravenous fentanyl (9.4%). The most underdosed medications were IN midazolam (23.5%) and intramuscular epinephrine 1:1000 (12.5%). The highest percentage of errors (20%) were seen in the zero to one-year-old age group.

CONCLUSION

After implementation of a precalculated mL dose system by patient age for EMS providers, most pediatric medications were reportedly administered within the appropriate dose range. A field guide with precalculated doses (in mL) may be an effective tool for reducing pediatric medication dosing errors by EMS providers.

Prevalence of using folk medicine and/or natural products in the treatment of hypertension problems compared with medicinal drugs in KSA

Introduction

Hypertension (HT), the silent killer, is highly prevalent in KSA due to several reasons. Some patients used to take non-pharmacological treatment for HT management.

Aim

This study focuses on the prevalence of using folk medicine and/or herbal drugs in HT treatment in Saudi Arabia.

Methods

Online questionnaires will be used as a study tool among the population in different regions of Saudi Arabia, keeping in mind all ethical aspects. A sample size of 240 will be taken. Univariate and multivariable regression data analyses were used to identify factors affecting the study. To make comparisons of the proportion, chi-squared tests will be used.

Results

By using online questionnaires conducted on 229 participants as a study tool among the population in different regions of Saudi Arabia, we found that only 30% of the participants tried treating their high blood pressure elevation using alternative or complementary medicine, and 42.2% and 32.5% using herbal therapy and Hyjama, respectively. They consider that using Allium sativum and Hibiscus sabdariffa has a great effect which is 44.1% and 32.9%, respectively, and only 10.5% from them consider that THM is not useful. The selected alternative or complementary medicine beneficial knowledge was from the Qur'an and the Sunnah of the Prophet. Additionally, social media helps in sharing the user/practitioner beliefs, attitudes, and experiences about THM.

Conclusion

From the previous study, we concluded that age and gender have a significant effect on health beliefs and behaviors which are associated with the use of herbal or alternative medicine in HT treatment.

Prevalence, Causes and Severity of Medication Administration Errors in the Neonatal Intensive Care Unit: A Systematic Review and Meta-Analysis

INTRODUCTION

Neonates are at greater risk of preventable adverse drug events as compared to children and adults.

OBJECTIVE

This study aimed to estimate and critically appraise the evidence on the prevalence, causes and severity of medication administration errors (MAEs) amongst neonates in Neonatal Intensive Care Units (NICUs).

METHODS

A systematic review and meta-analysis was conducted by searching nine electronic databases and the grey literature for studies, without language and publication date restrictions. The pooled prevalence of MAEs was estimated using a random-effects model. Data on error causation were synthesised using Reason's model of accident causation.

RESULTS

Twenty unique studies were included. Amongst direct observation studies reporting total opportunity for errors as the denominator for MAEs, the pooled prevalence was 59.3% (95% confidence interval [CI] 35.4-81.3, I² = 99.5%). Whereas, the non-direct observation studies reporting medication error reports as the denominator yielded a pooled prevalence of 64.8% (95% CI 46.6-81.1, I² = 98.2%). The common reported causes were error-provoking environments (five studies), while active failures were reported by three studies. Only three studies examined the severity of MAEs, and each utilised a different method of assessment.

CONCLUSIONS

This is the first comprehensive systematic review and meta-analysis estimating the prevalence, causes and severity of MAEs amongst neonates. There is a need to improve the quality and reporting of studies to produce a better estimate of the prevalence of MAEs amongst neonates. Important targets such as wrong administration-technique, wrong drug-preparation and wrong time errors have been identified to guide the implementation of remedial measures.

Characteristics and Consequences of Medication Errors in Pediatric Patients Reported to Ramathibodi Poison Center: A 10-Year Retrospective Study

Purpose

This study was performed to evaluate the clinical characteristics of, consequences of, and factors associated with medication errors (MEs) that cause harm to pediatric patients (<15 years of age) treated in the hospital setting.

Patients and Methods

We performed a 10-year retrospective study (January 2011–December 2020) by analyzing data from the Ramathibodi Poison Center. MEs were classified into categories A to I according to the severity of the outcome.

Results

In total, 121 patients were included in the study. Most (51.24%) patients were male. Their median age was 1 year (range, 1 hour–14 years). Infants, newborns, and toddlers were the three most common age groups in which MEs were reported. Most MEs occurred during the afternoon shift [n = 60 (49.59%)] and in the inpatient department (66.12%). The most common type of MEs was a dose error (64.46%). Antibiotics, sedative agents, and bronchodilators were the three most common classes of ME drugs. Four patients died. Three deaths occurred because of a dose error. One patient was a 1-year-old girl who received an iatrogenic intravenous phenytoin overdose of 10 times the normal dose, resulting in a phenytoin level of 72.4 mcg/mL. She died 22 hours after the ME occurred. The work shift was the only factor that significantly differed between patients with category C and D MEs and those with category E to I MEs.

Conclusion

Small children were at highest risk for MEs. MEs induced harm and deaths in some patients. A preventive and safety system, including appropriate shift work administration, should be emphasized and implemented to prevent and/or decrease the occurrence of MEs.

A validation of newly developed weight estimating tape for Korean pediatric patients

Pediatric drug dosages are based on body weight, so accurate measurement thereof is essential. However, this is not possible in emergencies. When using weight-estimating tapes, World Health Organization (WHO) growth charts serve as reference weights; however, local growth charts might be more accurate. This study developed a tape based on 2017 Korean National Growth Charts, which are more suitable for the Korean population than WHO growth charts, and evaluated its performance in a Korean pediatric population. This prospective cross-sectional study analyzed 792 pediatric patients who had visited the emergency department from June 2021 to December 2021. Weights were estimated using the Broselow tape (BT), Pediatric Advanced Weight Prediction in the Emergency Room XL (PAWPER XL), and Body Habitus-based Pediatric Emergency Tape (BHPET). The performance and measurement agreement of the tapes were analyzed. Among the tapes, the BHPET had the smallest mean absolute percentage error (MAPE), of 10.23%, and a root mean square percentage error (RMSPE) of 14.14%. Also, the percentage of weight estimations within 10% of the actual weight (PW10) was 59.6%, indicating better accuracy than the BT and PAWPER XL in all age groups. The intraclass correlation coefficients of the BT, PAWPER XL, and BHPET were 0.931, 0.977, and 0.985, respectively (p < 0.001). The performance and accuracy of the BHPET was similar or slightly superior to that of the other tapes. The body weight estimated using the BHPET for a local pediatric population was sufficiently correlated with the actual body weight.

A Clinical Decision Support System for Increasing Compliance with Protocols in Chemotherapy of Children with Acute Lymphoblastic Leukemia

Objective:

In this survey, a protocol-based Chemotherapy Prescription Decision Support System (CPDSS) was designed and evaluated to reduce medication errors in the chemotherapy process of children with ALL.

Methods:

The CPDSS algorithm was extracted by the software development team based on the protocol used by doctors to treat children with ALL. The ASP.Net MVC and SQL Server 2016 programming languages were used to develop the system. A 3-step evaluation (technical, retrospective, and user satisfaction) was performed on CPDSS designed at 2 children’s hospitals in Tehran. The data were analyzed using descriptive statistics. At the technical evaluation step, users provided recommendations included in the system.

Results:

In the retrospective CPDSS evaluation step, 1281 prescribed doses of the drugs related to 30 patients were entered into the system. CPDSS detected 735 cases of protocol deviations and 57 (95%, CI = 1.25-2.55) errors in prescribed chemotherapy for children with ALL. In the user satisfaction evaluation, the users approved two dimensions of the user interface and functionality of the system.

Conclusions:

With the provision of alerts, the CPDSS can help increase compliance with chemotherapy protocols and decrease the chemotherapy prescribing errors that can improve patient safety.

Medication Errors in Pediatrics: Proposals to Improve the Quality and Safety of Care Through Clinical Risk Management

Medication errors represent one of the most common causes of adverse events in pediatrics and are widely reported in the literature. Despite the awareness that children are at increased risk for medication errors, little is known about the real incidence of the phenomenon. Most studies have focused on prescription, although medication errors also include transcription, dispensing, dosage, administration, and certification errors. Known risk factors for therapeutic errors include parenteral infusions, oral fluid administration, and tablet splitting, as well as the off-label use of drugs with dosages taken from adult literature. Emergency Departments and Intensive Care Units constitute the care areas mainly affected by the phenomenon in the hospital setting. The present paper aims to identify the risk profiles in pediatric therapy to outline adequate preventive strategies. Precisely, through the analysis of the available evidence, solutions such as standardization of recommended doses for children, electronic prescribing, targeted training of healthcare professionals, and implementation of reporting systems will be indicated for the prevention of medication errors.

Errors in Antimicrobial Prescription and Administration in Very Low Birth Weight Neonates at a Tertiary South African Hospital

BACKGROUND

Antimicrobial prescription and administration-related errors occur frequently in very low birth weight (VLBW; <1,500 g) neonates treated for bloodstream infections (BSI).

METHODS

Antimicrobial prescriptions for the treatment of laboratory-confirmed BSI were retrospectively analyzed for VLBW neonates at Tygerberg Hospital, Cape Town, South Africa (1 July 2018 - 31 December 2019), describing antimicrobial type, indication, duration of therapy and BSI outcomes. The prevalence of, and risk factors for prescription (dose, interval) and administration errors (hang-time, delayed/missed doses) were determined.

RESULTS

One hundred and sixty-one BSI episodes [16 (9.9%)] early-onset, 145 [90.1%] healthcare-associated) affected 141 neonates (55% male, 25% born to mothers living with HIV, 46% <1,000 g birth weight) with 525 antimicrobial prescription episodes [median 3.0 (IQR 2-4) prescriptions/BSI episode]. The median duration of therapy for primary BSI, BSI-associated with meningitis and BSI-associated with surgical infections was 9, 22, and 28 days, respectively. The prevalence of dose and dosing interval errors was 15.6% (77/495) and 16.4% (81/495), respectively with prescription errors occurring most commonly for piperacillin-tazobactam and vancomycin given empirically. Administration errors were less frequent [3.8% (219/5,770) doses missed; 1.4% (78/5,770) delayed], however 64% had a hang-time (time from sepsis diagnosis to 1st dose of antimicrobial) exceeding 60 min. On multivariable analysis, postnatal age >7 days was associated with prescription errors (p = 0.028). The majority of neonates with BSI required escalation of respiratory support (52%) and 26% required intensive care admission. Despite fair concordance between empiric antimicrobial/s prescription and pathogen susceptibility (74.5%), BSI-attributable mortality in this cohort was 30.4%.

CONCLUSION

VLBW neonates with BSI's were critically ill and had high mortality rates. Hang-time to first antimicrobial administration was delayed in two-thirds of BSI episodes and prescription errors affected almost 1 in 6 prescriptions. Targets for intervention should include reducing hang-time, use of standardized antimicrobial dosing guidelines and implementation of antimicrobial stewardship recommendations.

Medication Order Errors at Hospital Admission Among Children With Medical Complexity

OBJECTIVES

We sought to characterize the nature and prevalence of medication order errors (MOEs) occurring at hospital admission for children with medical complexity (CMC), as well as identify the demographic and clinical risk factors for CMC experiencing MOEs.

METHODS

Prospective cohort study of 1233 hospitalizations for CMC from November 1, 2015, to October 31, 2016, at 2 children's hospitals. Medication order errors at admission were identified prospectively by nurse practitioners and a pharmacist through direct patient care. The primary outcome was presence of at least one MOE at hospital admission. Statistical methods used included χ2 test, Fisher exact tests, and generalized linear mixed models.

RESULTS

Overall, 6.1% (n = 75) of hospitalizations had ≥1 MOE occurring at admission, representing 112 total identified MOEs. The most common MOEs were incorrect dose (41.1%) and omitted medication (34.8%). Baclofen and clobazam were the medications most commonly associated with MOEs. In bivariable analyses, MOEs at admission varied significantly by age, assistance with medical technology, and numbers of complex chronic conditions and medications (P < 0.05). In multivariable analysis, patients receiving baclofen had the highest adjusted odds of MOEs at admission (odds ratio, 2.2 [95% confidence interval, 1.2-3.8]).

CONCLUSIONS

Results from this study suggest that MOEs are common for CMC at hospital admission. Children receiving baclofen are at significant risk of experiencing MOEs, even when orders for baclofen are correct. Several limitations of this study suggest possible undercounting of MOEs during the study period. Further investigation of medication reconciliation processes for CMC receiving multiple chronic, home medications is needed to develop effective strategies for reducing MOEs in this vulnerable population.

Medication Errors in Overweight and Obese Pediatric Patients: A Narrative Review

BACKGROUND

The childhood obesity epidemic in the United States has increased utilization of health care and prescribing of medications in overweight and obese children, yet it is unclear whether this has led to more medication errors. The objective of this study was to review all available literature on incidence and types of medication errors in overweight and obese children.

METHODS

A search of MEDLINE, Embase, and Scopus databases was conducted for all studies and oral abstracts through December 2020 reporting medication errors in overweight or obese children aged ≤ 18 years. All studies were identified and extracted via a Covidence database. Two reviewers independently reviewed studies and rated the methodologic quality of those included per GRADE (Grading of Recommendations, Assessment, Development and Evaluations) criteria.

RESULTS

The search identified 1,016 abstracts from databases. Following review, full text was obtained for 146 articles, of which 141 were excluded. A total of 5 studies met criteria for inclusion and described dosing errors of antimicrobials, anesthetics, and paracetamol in overweight and obese pediatric patients. Two of the 5 studies compared medication errors in obese to nonobese children, and both found that medication errors (both over- and underdosing) were generally more common among obese children. The identified reasons for medication errors included incorrect dosing weight, incorrect dosing strategy, over- and underdosing with weight-based and flat-fixed dosing, and inapposite use of age-based dosing schemas.

CONCLUSION

There is a paucity of patient safety evidence available evaluating medication use in overweight and obese children and associated medication errors. Overweight and obese children may be at increased risk of medication errors, although the clinical significance of this is unknown.

Arzneimittelnebenwirkungen und Medikationsfehler bei Kindern

Hintergrund

Kinder sind einem höheren Risiko für Nebenwirkungen (NW) und Medikationsfehler (MF) als Erwachsene ausgesetzt, auch weil es häufig an geeigneten Dosierungsempfehlungen, Arzneiformen und adäquaten Applikationsformen mangelt.

Material und Methode

Kurze Literaturübersicht und Auswertung von Spontanberichten aus der Datenbank EudraVigilance bezüglich NW zu Kindern zwischen 2000 und 2019 sowie einer Datensammlung zu MF bei Kindern zwischen 2014 und 2020 in Deutschland.

Ergebnisse

MPH als zentral wirksames Sympathomimetikum wird zur Behandlung der Aufmerksamkeitsdefizit‑/Hyperaktivitätsstörung (ADHS) eingesetzt.

Im Bewertungszeitraum 2014–2020 wurden dem Bundesinstitut für Arzneimittel und Medizinprodukte 151 MF direkt gemeldet. Häufig gemeldet wurden nicht korrekt durchgeführte Zubereitungen von Arzneimitteln, wie z. B. bei antibiotischen Trockensäften, die zu fehlerhaften Dosierungen führten.

Schlussfolgerung

Zudem sollten andere Informationsquellen (z. B. Dosierungsdatenbanken) intensiv genutzt werden, zum einen, um bereits vorhandene Informationen im klinischen und im ambulanten Setting besser umzusetzen, zum anderen, um die Kenntnisse zu Anwendungsrisiken bei Kindern zu verbessern. Diesbezüglich sollte die Meldebereitschaft der Ärzte- und Apothekerschaft zu NW und MF weiter erhöht werden.

Systemic Causes of In-Hospital Intravenous Medication Errors: A Systematic Review

OBJECTIVES

Delivery of intravenous medications in hospitals is a complex process posing to systemic risks for errors. The aim of this study was to identify systemic causes of in-hospital intravenous medication errors.

METHODS

A systematic review adhering to PRISMA guidelines was conducted. We searched MEDLINE (Ovid), Scopus, CINAHL, and EMB reviews for articles published between January 2005 and June 2016. Peer-reviewed journal articles published in English were included. Two reviewers independently selected articles according to a predetermined PICO tool. The quality of studies was assessed using the GRADE system and the evidence analyzed using qualitative content analysis.

RESULTS

Eleven studies from six countries were included in the analysis. We identified systemic causes related to prescribing (n = 6 studies), preparation (n = 6), administration (n = 6), dispensing and storage (n = 5), and treatment monitoring (n = 2). Administration, prescribing, and preparation were the process phases most prone to systemic errors. Insufficient actions to secure safe use of high-alert medications, lack of knowledge of the drug, calculation tasks, failure in double-checking procedures, and confusion between look-alike, sound-alike medications were the leading causes of intravenous medication errors. The number of the included studies was limited, all of them being observational studies and graded as low quality.

CONCLUSIONS

Current intravenous medication systems remain vulnerable, which can result in patient harm. Our findings suggest further focus on medication safety activities related to administration, prescribing, and preparation of intravenous medications. This study provides healthcare organizations with preliminary knowledge about systemic causes of intravenous medication errors, but more rigorous evidence is needed.

How to use low-molecular-weight heparin to treat neonatal thrombosis in clinical practice

Among children, neonates have the highest incidence of thrombosis due to risk factors such as catheter instrumentation, an evolving coagulation system and congenital heart disease. Low-molecular-weight heparins (LMWHs) are the most commonly used anticoagulants in neonates. Published guidelines delineate dosing and monitoring protocols for LMWH therapy in newborns. However, challenging clinical situations frequently present that warrant healthcare providers to think critically beyond the range of guidelines, and judiciously resolve specific problems. This review describes the use of LMWH in the neonatal population, including practical aspects such as route and site of administration, preparation from concentrated formulations and methods to minimize pain of subcutaneous injection. It is followed by a discussion on dosing, monitoring and outcomes of LMWH therapy in neonates. The risk of recurrence of thrombosis in neonates after LMWH therapy is approximately 3% based on a pooled analysis of studies reporting this outcome over the last 24 years. The article concludes with an overview of the side-effects of LMWH, including the risk of bleeding which is around 4% based on pooled analyses of more than 30 studies.

Role of the nurses in partnering with mothers to give oral medication to their hospitalised child: Modification and development of a contextualised evidence-based practice guideline

Background

In paediatric wards, children are often reluctant to receive medication from nurses and eventually it is given by the parents. It is a common practice for nurses to hand the medication to mothers to give to their children, However, it is an ‘informal’ practice and lacks evidence-based guidelines.

Objectives

To develop a contextualised and adapted evidence-based guideline to support nurses to partner with mothers/carers so that they can safely give oral medication to their hospitalised child under the supervision of a competent nurse.

Method

Existing relevant guidelines were identified through searches of bibliographic databases and websites. The AGREE II: Appraisal of Guidelines for Research and Evaluation II instrument was used to appraise the quality of the identified sources. The process of guideline adaptation recommended by the South African Guidelines Excellence project was followed, and a list of adapted recommendations was developed, aligned with the legislative and regulatory frameworks for nursing in South Africa. Accessible end user documentation was developed.

Results

Six sources were screened and three sources were found to be eligible and were subjected to full appraisal. Two guidelines and one policy document were identified as suitable for adaptation. Expert consultation confirmed that the resulting adapted guideline was sound, easy to understand, and well presented for the target audience.

Conclusion

This process successfully led to the development of a modified evidence-based practice guideline to enable nurses to partner with mothers/caregivers in safely giving oral medication to their hospitalised child in lower-resourced African settings.

Prevalence and Nature of Medication Errors and Medication-Related Harm Following Discharge from Hospital to Community Settings: A Systematic Review

Background

Little is known about the epidemiology of medication errors and medication-related harm following transition from secondary to primary care. This systematic review aims to identify and critically evaluate the available evidence on the prevalence and nature of medication errors and medication-related harm following hospital discharge.

Methods

Studies published between January 1990 and March 2019 were searched across ten electronic databases and the grey literature. No restrictions were applied with publication language or patient population studied. Studies were included if they contained data concerning the rate of medication errors, unintentional medication discrepancies, or adverse drug events. Two authors independently extracted study data.

Results

Fifty-four studies were included, most of which were rated as moderate (39/54) or high (7/54) quality. For adult patients, the median rate of medication errors and unintentional medication discrepancies following discharge was 53% [interquartile range 33–60.5] (n = 5 studies) and 50% [interquartile range 39–76] (n = 11), respectively. Five studies reported adverse drug reaction rates with a median of 27% [interquartile range 18–40.5] and seven studies reported adverse drug event rates with a median of 19% [interquartile range 16–24]. For paediatric patients, one study reported a medication error rate of 66.3% and another an adverse drug event rate of 9%. Almost a quarter of studies (13/54, 24%) utilised a follow-up period post-discharge of 1 month (range 2–180 days). Drug classes most commonly implicated with adverse drug events were antibiotics, antidiabetics, analgesics and cardiovascular drugs.

Conclusions

This is the first systematic review to explore the prevalence and nature of medication errors and adverse drug events following hospital discharge. Targets for future work have been identified.

Predicting self-intercepted medication ordering errors using machine learning

Current approaches to understanding medication ordering errors rely on relatively small manually captured error samples. These approaches are resource-intensive, do not scale for computerized provider order entry (CPOE) systems, and are likely to miss important risk factors associated with medication ordering errors. Previously, we described a dataset of CPOE-based medication voiding accompanied by univariable and multivariable regression analyses. However, these traditional techniques require expert guidance and may perform poorly compared to newer approaches. In this paper, we update that analysis using machine learning (ML) models to predict erroneous medication orders and identify its contributing factors. We retrieved patient demographics (race/ethnicity, sex, age), clinician characteristics, type of medication order (inpatient, prescription, home medication by history), and order content. We compared logistic regression, random forest, boosted decision trees, and artificial neural network models. Model performance was evaluated using area under the receiver operating characteristic curve (AUROC) and the area under the precision-recall curve (AUPRC). The dataset included 5,804,192 medication orders, of which 28,695 (0.5%) were voided. ML correctly classified voids at reasonable accuracy; with a positive predictive value of 10%, ~20% of errors were included. Gradient boosted decision trees achieved the highest AUROC (0.7968) and AUPRC (0.0647) among all models. Logistic regression had the poorest performance. Models identified predictive factors with high face validity (e.g., student orders), and a decision tree revealed interacting contexts with high rates of errors not identified by previous regression models. Prediction models using order-entry information offers promise for error surveillance, patient safety improvements, and targeted clinical review. The improved performance of models with complex interactions points to the importance of contextual medication ordering information for understanding contributors to medication errors.

Dosing Accuracy of Oral Extemporaneous Suspensions of Antibiotics: Measuring Procedures and Administration Devices

Extemporaneous suspensions are often marketed with several administration devices that can be freely used by patients/caregivers. The homogeneity of suspensions requires shaking before use. Hence, it is crucial to assess the precision of all devices and the users’ awareness of the shaking procedure. This study was conducted at University Institute Egas Moniz with 40 pharmacy students who were asked to measure 2.5 and 5 mL of two extemporaneous azithromycin suspensions. Formulation A is marketed with a double-dosing spoon and oral syringe, whereas B includes a transparent dosing spoon. Both have a reconstitution cup. The user’s preference for administration devices, the degree of compliance with the ‘shake before use’ instruction and the accuracy of the manipulation were assessed. The double-dosing spoon was the preferred device. The “shake before use” instruction was overlooked by most volunteers. The average measured volumes obtained with the double-dosing spoon were significantly different from the ones obtained with the oral syringe (p < 0.001) and significantly lower than the reference dose (p < 0.001). The oral syringe originates significantly higher values than the reference dose (p < 0.001). The dosing spoons values were significantly different from each other (p < 0.001). Liquid medicines containing several administration devices may be a challenge since they are nonequivalent.

Evaluation of medication error rates in Saudi Arabia: A protocol for systematic review and meta-analysis

INTRODUCTION

Due to the diversity of reports and on the rates of medications errors (MEs) in Saudi Arabia, we performed the first meta-analysis to determine the rate of medications errors in Saudi Arabia using meta-analysis in the hospital settings.

METHODS

We conducted a systematic literature search through August 2019 using PubMed, EMBASE, CINAHL, PsycINFO, and Google Scholar to identify all observational studies conducted in hospital settings in Saudi Arabia that reported the rate of MEs. A random-effects models were used to calculate overall MEs, as well as prescribing, dispensing, and administration error rates. The I2 statistics were used to analyze heterogeneity.

RESULTS

Sixteen articles were included in this search. The total incidence of MEs in Saudi Arabia hospitals was estimated at 44.4%. Prescribing errors, dispensing errors, and adminstration errors incidents represent 40.2%, 28.2%, and 34.5% out of the total number of reported MEs, respectively. However, between-study heterogeneity was also generally found to be >90% (I-squared statistic).

CONCLUSIONS

This study demonstrates the MEs common in health facilities. Additional efforts in the field are needed to improve medication management systems in order to prevent patient harm incidents.

Impact of computerised physician order entry (CPOE) on the incidence of chemotherapy-related medication errors: a systematic review

Purpose

Computerised prescriber (or physician) order entry (CPOE) implementation is one of the strategies to reduce medication errors. The extent to which CPOE influences the incidence of chemotherapy-related medication errors (CMEs) was not previously collated and systematically reviewed. Hence, this study was designed to collect, collate, and systematically review studies to evaluate the effect of CPOE on the incidence of CMEs.

Methods

A search was performed of four databases from 1 January 1995 until 1 August 2019. English-language studies evaluating the effect of CPOE on CMEs were selected as per inclusion and exclusion criteria. The total CMEs normalised to total prescriptions pre- and post-CPOE were extracted and collated to perform a meta-analysis using the ‘meta’ package in R. The systematic review was registered with PROSPERO CRD42018104220.

Results

The database search identified 1621 studies. After screening, 19 studies were selected for full-text review, of which 11 studies fulfilled the selection criteria. The meta-analysis of eight studies with a random effects model showed a risk ratio of 0.19 (95% confidence interval: 0.08–0.44) favouring CPOE (I² = 99%).

Conclusion

The studies have shown consistent reduction in CMEs after CPOE implementation, except one study that showed an increase in CMEs. The random effects model in the meta-analysis of eight studies showed that CPOE implementation reduced CMEs by 81%.

Construction and analysis of a database for medication errors in a pharmacovigilance centre-the Moroccan experience

PURPOSE

The study aimed to describe the epidemiological profile of medication errors (MEs) reported to the Moroccan Pharmacovigilance Center (MPVC), to determine factors associated with serious MEs, and to describe signals related to them.

METHODS

We carried out a retrospective descriptive analysis of MEs reported to the MPVC from 2006 to 2016 and a secondary analysis of the seriousness of MEs with adverse drug reactions (ADRs). The reports were sorted by demographic profile and by ME and ADR characteristics. For signal detection, a quantitative approach was adopted, and the root cause analysis was completed. Epi info 7 software was used to perform descriptive and analytical statistics. The statistical significance level was set at p < 0.05.

RESULTS

A total of 1618 ME reports were retrieved. The proportion of MEs associated with serious ADRs was 23.9%. The factors statistically associated with serious MEs were as follows: (i) the age group 16 years old and less (p < 0.001), (ii) the gender (p = 0.01), (iii) the administration and the prescription stages (p < 0.001), and (iv) the ME types related to inappropriate schedule of drug administration, drug prescribing error (p < 0.001), and incorrect drug administration dosage form (p = 0.04). Fourteen signals related to MEs were detected, for which risk minimization actions were implemented.

CONCLUSION

The establishment of a ME unit within the MPVC was an opportunity to further improve the pharmacovigilance centre performance and consequently its contribution to medication safety. The lessons learned from MEs should be shared through pharmacovigilance networks and with institutions involved in medication safety for synergistic results to achieve patient safety worldwide.

Medication errors: a focus on nursing practice

Objectives

Health departments endeavor to give care to individuals to remain in healthy conditions. Medications errors (MEs), one of the most types of medical errors, could be venomous in clinical settings. Patients will be harmed physically and psychologically, in addition to adverse economic consequences. Reviewing and understanding the topic of medication error especially by nurses can help in advancing the medical services to patients.

Methods

A search using search engines such as PubMed and Google scholar were used in finding articles related to the review topic.

Key findings

This review highlighted the classifications of MEs, their types, outcomes, reporting process, and the strategies of error avoidance. This summary can bridge and open gates of awareness on how to deal with and prevent error occurrences. It highlights the importance of reporting strategies as mainstay prevention methods for medication errors.

Conclusions

Medication errors are classified based on multifaceted criteria and there is a need to standardize the recommendations and make them a central goal all over the globe for the best practice. Nurses are the frontlines of clinical settings, encouraged to be one integrated body to prevent the occurrence of medication errors. Thus, systemizing the guidelines are required such as education and training, independent double checks, standardized procedures, follow the five rights, documentation, keep lines of communication open, inform patients of drug they receive, follow strict guidelines, improve labeling and package format, focus on the work environment, reduce workload, ways to avoid distraction, fix the faulty system, enhancing job security for nurses, create a cultural blame-free workspace, as well as hospital administration, should support and revise processes of error reporting, and spread the awareness of the importance of reporting.

Characteristics of Reported Pediatric Medication Errors in Northern Ireland and Use in Quality Improvement

BACKGROUND

To protect children from harm, clinicians, educators, and patient safety champions need information to direct improvement efforts. Critical incident data could provide this but are often disregarded as a source of evidence because under-reporting makes them an inaccurate measure of error rates.

OBJECTIVE

Our aim was to identify key targets for pediatric healthcare quality improvement. The objective was to evaluate the types, characteristics, and areas of risk within reported medication errors in pediatric patients.

METHODS

We conducted a retrospective study of a large regional dataset of 1522 pediatric medication errors reported from secondary care between 2011 and 2015, including all hospitals and community pediatric settings in Northern Ireland. The following characteristics were included: error severity, patient age, drug involved, error type, and area of practice. Two academic pediatricians, a senior medicines governance pharmacist, a Reader in Pharmacy Practice, and a Professor of Medical Education analyzed the data. Validity checks included comparing the findings against key published literature and discussion by a practitioner panel representing five multidisciplinary stakeholder groups.

RESULTS

Neonates, particularly in intensive care, were implicated in 19% of all errors. The medications most represented in risk were antimicrobials, paracetamol, vaccines, and intravenous fluids. The error types most implicated were dosing errors (32%) and omissions (21%).

CONCLUSIONS

Incident reports identified neonates, a shortlist of drugs, and specific error types, associated with modifiable behaviors, as priority improvement targets. These findings direct further study and inform intervention development, such as specific training in calculations to prevent dosing errors. Involving experienced practitioners both endorsed the findings and engaged the practice community in their future implementation. The utility of incident reports to direct improvement efforts may offset the limitations in their representativeness.

Pediatric pharmacists' perspectives on essential skills and activities for community pharmacists caring for pediatric patients: A mixed-methods study

BACKGROUND

Provision of care to pediatric patients represents a set of unique challenges for pharmacists. Pharmacists practising in pediatric-specialty areas (acute care or ambulatory) have unique perspectives on approaches to pediatric care that can be shared to support pharmacists less familiar with this group of patients in providing effective, patient-centred care.

METHODS

This was a mixed-methods study using data from pharmacist interviews to quantify and qualitatively describe the approaches to care most commonly reported by pediatric-specialty pharmacists when asked to provide advice to pharmacists on providing pharmaceutical care to infants and children. Data were coded in duplicate using an inductive approach, and discrepancies were resolved by consensus. The number of times a theme (or subtheme) was mentioned and the number of pharmacists who mentioned it were used as markers of the relative importance of the content.

RESULTS

The themes (and subthemes) that emerged as most important were clinical activities (dose checks, considering indication, using up-to-date height/weight), caregiver counselling (demonstrating measurement, discussing administration), medication safety (using consistent concentrations of liquids), compounded medications (risks of, use of caution), adherence (formulation considerations, palatability), avoiding use of over-the counter products (except analgesics/antipyretics) and use of external supports (colleagues, caregivers, resources).

CONCLUSIONS

We present a collated and prioritized list of practical approaches for pharmacists to use when caring for pediatric patients across the spectrum of practice. Can Pharm J (Ott) 2020;153:xx-xx.

Parental Experience of Potential Adverse Drug Reactions Related to Their Oral Administration of Antipyretic Analgesic Medicines in Children in Saudi Arabia

BACKGROUND

Oral antipyretic analgesic medicines are commonly used in children and have the potential for adverse drug reactions (ADRs).

OBJECTIVE

The aim of this study was to explore parental experiences of potential ADRs related to their oral administration of antipyretic analgesics in children in the Kingdom of Saudi Arabia.

METHODS

For this cross-sectional survey, a paper-based questionnaire, consent form and information sheet were handed out to 1000 parents who had administered an oral antipyretic analgesic medicine to their children during the previous 3 months. Data were entered and analyzed using SPSS version 21.0 (IBM-SPSS Inc, Armonk, NY). Simple descriptive and inferential statistics were used. Management and ethical approvals were attained.

RESULTS

During March to April 2017, 661 parents agreed to participate, giving a response rate of 66.1%. Of the surveyed sample, 208 parents had observed 1 or more potential ADRs (31.5%, n = 208 out of 661). Parents' (n = 208) most commonly reported potential ADRs (n = 523) were loss of appetite (23%, n = 120 out of 523), stomachache (20.3%, n = 106 out of 523), abdominal colic (13%, n = 68 out of 523), and diarrhea (10.3%, n = 54 out of 523). Parents described severity of the ADRs as slight (71.8%, n = 342 out of 476), annoying to the child (7.9%, n = 85 to of 476), significant and affecting daily tasks (3.6%, n = 17 out of 476) and significant and led to the hospital (6.7%, n = 32 out of 476). Fever was the top-ranked reason for using antipyretic analgesic medicines (41.0%, n = 271 out of 661), followed by toothache (25.0%, n = 165 out of 661) and tonsillitis/laryngitis (24.7%, n = 163 out of 661). Among parents, 34.7% (n = 165 out of 476) did not seek medical attention when a potential ADR occurred, whereas 26.3% (n = 125 out of 476) of parents took their children to hospital clinics.

CONCLUSIONS

Although the majority of parentally reported (but not proven) ADRs were mild, a number of significant ADRs were reported. Future research should consider whether there is a role for physicians and pharmacists in educating parents in Saudi Arabia, and perhaps more widely, about the optimal use of oral antipyretic and analgesic medicines in children.

Descriptive study of discharge medications in pediatric patients

Background:

Limited studies have evaluated medications in children discharged from hospitals. Knowledge of the number of medications and dosage forms could provide a baseline to establish a medication discharge prescription program.

Objectives:

To identify the median number of discharge prescriptions per patient. Secondary objectives included an evaluation of the dosage formulations and frequency, and comparisons of the prevalence of unrounded medication doses between service type (medical vs surgical) and physician provider level (trainees vs attendings).

Methods:

This retrospective study included children <18 years receiving >1 discharge prescription during 4 selected months over a 1-year time frame. Comparisons were made via Pearson’s chi-square tests, Fisher’s Exact tests, and Kruskal–Wallis nonparametric rank tests as appropriate with a priori p value of <0.05.

Results:

A total of 852 patients were evaluated, with most (78.8%) on a medical service. The median (interquartile range) number of new medications at discharge was 2 (1–3), with the median total number of discharge medications of 3 (2–6). There was no difference in the net change of the median number of home medications stopped and new medications started between service types. The majority (72.2%) received >1 oral liquid medications. There was no difference in prescribing rates per service type and provider level. There was a difference in the number of unrounded doses between trainees versus attendings, 17.8% versus 9.5%, p = 0.048.

Conclusion:

Patients were discharged on a median of three medications, and most received >1 oral liquid medications. These data can be used to target children who would benefit from medication discharge prescription programs.

Prevalence of Medication Errors Among Paediatric Inpatients: Systematic Review and Meta-Analysis

INTRODUCTION

The risk of medication errors is high in paediatric inpatient settings. However, estimates of the prevalence of medication errors have not accounted for heterogeneity across studies in error identification methods and definitions, nor contextual differences across wards and the use of electronic or paper medication charts.

OBJECTIVE

Our aim was to conduct a systematic review and meta-analysis to provide separate estimates of the prevalence of medication errors among paediatric inpatients, depending on hospital ward and the use of electronic or paper medication charts, that address differences in error identification methods and definitions.

METHODS

We systematically searched five databases to identify studies published between January 2000 and December 2018 that assessed medication error rates by medication chart audit, direct observation or a combination of methods.

RESULTS

We identified 71 studies, 19 involved paediatric wards using electronic charts. Most studies assessed prescribing errors with few studies assessing administration errors. Estimates varied by ward type. Studies of paediatric wards using electronic charts generally reported a reduced error prevalence compared to those using paper, although there were some inconsistencies. Error detection methods impacted the rate of administration errors in studies of multiple wards, however, no other difference was found. Definition of medication error did not have a consistent impact on reported error rates.

CONCLUSIONS

Medication errors are a frequent occurrence in paediatric inpatient settings, particularly in intensive care wards and emergency departments. Hospitals using electronic charts tended to have a lower rate of medication errors compared to those using paper charts. Future research employing controlled designs is needed to determine the true impact of electronic charts and other interventions on medication errors and associated harm among hospitalized children.

Prevalence and Nature of Medication Errors and Preventable Adverse Drug Events in Paediatric and Neonatal Intensive Care Settings: A Systematic Review

INTRODUCTION

Children admitted to paediatric and neonatal intensive care units may be at high risk from medication errors and preventable adverse drug events.

OBJECTIVE

The objective of this systematic review was to review empirical studies examining the prevalence and nature of medication errors and preventable adverse drug events in paediatric and neonatal intensive care units.

DATA SOURCES

Seven electronic databases were searched between January 2000 and March 2019.

STUDY SELECTION

Quantitative studies that examined medication errors/preventable adverse drug events using direct observation, medication chart review, or a mixture of methods in children ≤ 18 years of age admitted to paediatric or neonatal intensive care units were included.

DATA EXTRACTION

Data on study design, detection method used, rates and types of medication errors/preventable adverse drug events, and medication classes involved were extracted.

RESULTS

Thirty-five unique studies were identified for inclusion. In paediatric intensive care units, the median rate of medication errors was 14.6 per 100 medication orders (interquartile range 5.7-48.8%, n = 3) and between 6.4 and 9.1 per 1000 patient-days (n = 2). In neonatal intensive care units, medication error rates ranged from 4 to 35.1 per 1000 patient-days (n = 2) and from 5.5 to 77.9 per 100 medication orders (n = 2). In both settings, prescribing and medication administration errors were found to be the most common medication errors, with dosing errors the most frequently reported error subtype. Preventable adverse drug event rates were reported in three paediatric intensive care unit studies as 2.3 per 100 patients (n = 1) and 21-29 per 1000 patient-days (n = 2). In neonatal intensive care units, preventable adverse drug event rates from three studies were 0.86 per 1000 doses (n = 1) and 0.47-14.38 per 1000 patient-days (n = 2). Anti-infective agents were commonly involved with medication errors/preventable adverse drug events in both settings.

CONCLUSIONS

Medication errors occur frequently in critically ill children admitted to paediatric and neonatal intensive care units and may lead to patient harm. Important targets such as dosing errors and anti-infective medications were identified to guide the development of remedial interventions.

Bibliometric Analysis of Medication Errors and Adverse Drug Events Studies

OBJECTIVES

Medication errors and adverse drug events are a key concern of the health-care industry. The objectives of this study were to map the intellectual structure of the studies of medication errors and adverse drug events and to investigate the developing path of this literature and interrelationships among the main topics.

METHODS

The Web of Science database was searched for documentation of medication errors and adverse drug events from 1961 to 2013. The most cited articles and references were profiled and analyzed using HistCite software to draw a historiograph and Ucinet software to draw a sociogram.

RESULTS

The database search revealed 3343 medication errors and 3342 adverse drug event documents. The most cited articles on medication errors focused on 3 key themes from 1961 to 2013, namely, medication errors in adult inpatients, computerized physician order entry in medication error studies, and medication errors in pediatric inpatients. The developing path for the most cited articles about adverse drug events from 1987 to 2013 was as follows: detection, analysis, effect, and prevention from adult inpatient to pediatric inpatient settings and from hospitalized care to ambulatory care. In addition, social network analysis based on the most cited references revealed a close relationship between medication errors and adverse drug events.

CONCLUSIONS

The mapping results provide a valuable tool for researchers to access the literature in this field and can be used to help identify the direction of medication errors and adverse drug events research.

Impact of pharmacist interventions on medication errors in hospitalized pediatric patients: a systematic review and meta-analysis

Background Medication errors are avoidable events that may occur at any stage of the medication use process. Implementing a clinical pharmacist is one strategy that is believed to reduce the number of medication errors. Pediatric patients, who are more vulnerable to medication errors due to several contributing factors, may benefit from the interventions of a pharmacist. Aim of the review To qualitatively and quantitatively evaluate the impact of clinical pharmacist interventions on medication error rates for hospitalized pediatric patients. Methods PubMed, EMBASE, Cochrane Controlled Trials Register and Google Scholar search engines were searched from database inception to February 2020. Study selection, data extraction and quality assessment was conducted by two independent reviewers. Observational and interventional studies were included. Data extraction was done manually and the Crowe Critical Appraisal Tool was used to critically appraise eligible articles. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a random-effects model for rates of medication errors. Results 19 studies were systematically reviewed and 6 studies (29,291 patients) were included in the meta-analysis. Pharmacist interventions involved delivering educational sessions, reviewing prescriptions, attending rounds and implementing a unit-based clinical pharmacist. The systematic review indicated that the most common trigger for pharmacist interventions was inappropriate dosing. Pharmacist involvement was associated with significant reductions in the overall rate of medication errors occurrence (OR 0.27; 95% CI 0.15 to 0.49). Conclusion Pharmacist interventions are effective for reducing medication error rates in hospitalized pediatric patients.

Standardising the Classification of Harm Associated with Medication Errors: The Harm Associated with Medication Error Classification (HAMEC)

Classifying harm associated with a medication error can be time consuming and labour intensive and limited studies undertake this step. There is no standardised process, and few studies that report harm assessment provide adequate methods to allow for study replication. Studies typically mention that a clinical review panel classified patient harm and provide a reference to a classification tool. Moreover, in many studies it is unclear whether potential or actual harm was classified as studies refer only to ‘error severity’. The tools used to categorise the severity of patient harm vary widely across studies and few have been assessed for inter-rater reliability and criterion validity. In this paper, we describe the systematic process we undertook to synthesise the defining elements and strengths, while mitigating the limitations, of existing harm classification tools to derive the Harm Associated with Medication Error Classification (HAMEC). This new tool provides a harm classification for use across clinical and research settings. The provision of an explicit process for its application and guiding category descriptors are designed to reduce the risk of misclassification and produce results that are comparable across studies. As the World Health Organisation embarks on its international safety challenge of reducing medication-related harm by 50%, accompanying methodological advances are required to measure progress.

[Impact of introducing assisted electronic prescription on paediatric patient safety]

OBJECTIVE

There have been very few studies on the effect of assisted electronic prescription on paediatric patient safety. The objective of this study is to compare medication errors that occurred before and after its introduction in a tertiary hospital.

MATERIAL AND METHODS

A quasi-experimental comparative study of medication errors detected before and after assisted electronic prescription introduction. All treatment lines were analysed in order to detect the point in the chain where the medication error occurred, as well as its type and cause. A Delphi study was conducted on the importance of each medication error involving doctors, nurses, and pharmacists.

RESULTS

The study included 166 patients (83 at each stage). At least one medication error was detected in 92% in the pre-introduction phase patients (2.8±2.1 errors/patient) and 7.2% of post-introduction phase patients (0.1±0.4 errors/patient). The assisted electronic prescription led to an absolute risk reduction of 40% (95% confidence interval=35.6-44.4%). The main cause of error was lapses and carelessness in both stages. Medication errors were considered serious in 9.5% of cases in the pre-introduction phase, while all of them were mild or moderate in the post-introduction phase.

CONCLUSIONS

The assisted electronic prescription implementation with prescription, validation and medication administration assistance systems significantly reduces medication errors and eliminates serious errors.

Mapping the prevalence and nature of drug related problems among hospitalised children in the United Kingdom: a systematic review

BACKGROUND

Problems arising from medicines usage are recognised as a key patient safety issue. Children are a particular concern, given that they are more likely than adults to experience medication-related harm. While previous reviews have provided an estimate of prevalence in this population, these predate recent developments in the delivery of paediatric care. Hence, there is a need for an updated, focussed and critical review of the prevalence and nature of drug-related problems in hospitalised children in the UK, in order to support the development and targeting of interventions to improve medication safety.

METHODS

Nine electronic databases (Medline, Embase, CINAHL, PsychInfo, IPA, Scopus, HMIC, BNI, The Cochrane library and clinical trial databases) were searched from January 1999 to April 2019. Studies were included if they were based in the UK, reported on the frequency of adverse drug reactions (ADRs), adverse drug events (ADEs) or medication errors (MEs) affecting hospitalised children. Quality appraisal of the studies was also conducted.

RESULTS

In all, 26 studies were included. There were no studies which specifically reported prevalence of adverse drug events. Two adverse drug reaction studies reported a median prevalence of 25.6% of patients (IQR 21.8-29.9); 79.2% of reactions warranted withdrawal of medication. Sixteen studies reported on prescribing errors (median prevalence 6.5%; IQR 4.7-13.3); of which, the median rate of dose prescribing errors was 11.1% (IQR 2.9-13). Ten studies reported on administration errors with a median prevalence of 16.3% (IQR 6.4-23). Administration technique errors represented 53% (IQR 52.7-67.4) of these errors. Errors detected during medicines reconciliation at hospital admission affected 43% of patients, 23% (Range 20.1-46) of prescribed medication; 70.3% (Range 50-78) were classified as potentially harmful. Medication errors detected during reconciliation on discharge from hospital affected 33% of patients and 19.7% of medicines, with 22% considered potentially harmful. No studies examined the prevalence of monitoring or dispensing errors.

CONCLUSIONS

Children are commonly affected by drug-related problems throughout their hospital journey. Given the high prevalence and risk of patient harm,, there is a need for a deeper theoretical understanding of paediatric medication systems to enable more effective interventions to be developed to improve patient safety.

Medication Errors and Their Relationship with Care Complexity and Work Dynamics

BACKGROUND:

Medication errors are currently known as the most common medical errors. Research shows that work environment and organisation management, in addition to the role of nurses, contribute to the occurrence of an error.

AIM:

Therefore, the present study was conducted to determine the rate of nurses’ medication errors and its relation to the care complexity and work dynamics in the Taleghani Pediatric Hospital of Gorgan in 2017.

MATERIAL AND METHODS:

This was a descriptive-correlational and cross-sectional study. Sampling was done through census method (N = 100). The data collection tools consisted of four questionnaires of demographic information, Salyer work dynamics, Medication Administration Errors, and Velasquez Nursing Care Complexity. Data were analysed in SPSS V.16 software using descriptive and inferential statistical methods including independent t-test and Pearson’s correlation.

RESULTS:

Medication calculation errors, wrong dose and wrong medication were the most common non-injectable medication errors, respectively. Drug incompatibility, wrong infusion rate and medication calculation errors were the most common injectable medication errors, respectively. There was a positive correlation between medication calculation errors (P = 0.02, r = 0.23), wrong solvent (P = 0.04, r = 0.21), and drug incompatibility (P = 0.01, r = 0.25) with amount of work dynamics. Also, there was a positive correlation between medication calculation errors (P = 0.03, r = 0.22) and wrong medication (P = 0.00, r = 0.31) with the nursing care complexity.

CONCLUSION:

Regarding the irrefutable impact of working conditions on the occurrence of errors, it appears that the study and complete recognition of nurses’ working conditions and their adjustment would lead to a reduction in medication errors.

Extended Versus Narrow-spectrum Antibiotics in the Management of Uncomplicated Appendicitis in Children: A Propensity-matched Comparative Effectiveness Study

OBJECTIVE

The aim of this study was to compare the effectiveness of extended versus narrow spectrum antibiotics in preventing surgical site infections (SSIs) and hospital revisits in children with uncomplicated appendicitis.

SUMMARY OF BACKGROUND DATA

There is a paucity of high-quality evidence in the pediatric literature comparing the effectiveness of extended versus narrow-spectrum antibiotics in the prevention of SSIs associated with uncomplicated appendicitis.

METHODS

Clinical data from the ACS NSQIP-Pediatric Appendectomy Pilot Project were merged with antibiotic utilization data from the Pediatric Health Information System database for patients undergoing appendectomy for uncomplicated appendicitis at 17 hospitals from January 1, 2013 to June 30, 2015. Patients who received piperacillin/tazobactam (extended spectrum) were compared with those who received either cefoxitin or ceftriaxone with metronidazole (narrow spectrum) after propensity matching on demographic and severity characteristics. Study outcomes were 30-day SSI and hospital revisit rates.

RESULTS

Of the 1389 patients included, 39.1% received piperacillin/tazobactam (range by hospital: 0% to 100%), and the remainder received narrow-spectrum agents. No differences in demographics or severity characteristics were found between groups following matching. In the matched analysis, the rates of SSI were similar between groups [extended spectrum: 2.4% vs narrow spectrum 1.8% (odds ratio, OR: 1.05, 95% confidence interval, 95% CI 0.34-3.26)], as was the rate of revisits [extended spectrum: 7.9% vs narrow spectrum 5.1% (OR: 1.46, 95% CI 0.75-2.87)].

CONCLUSIONS

Use of extended-spectrum antibiotics was not associated with lower rates of SSI or hospital revisits when compared with narrow-spectrum antibiotics in children with uncomplicated appendicitis. Our results challenge the routine use of extended-spectrum antibiotics observed at many hospitals, particularly given the increasing incidence of antibiotic-resistant organisms.

What causes prescribing errors in children? Scoping review

OBJECTIVES

(1) Systematically assemble, analyse and synthesise published evidence on causes of prescribing error in children. (2) Present results to a multidisciplinary group of paediatric prescribing stakeholders to validate findings and establish how causative factors lead to errors in practice.

DESIGN

Scoping review using Arksey and O'Malley's framework, including stakeholder consultation; qualitative evidence synthesis.

METHODS

We followed the six scoping review stages. (1) Research question-the research question was 'What is known about causes of prescribing error in children?' (2) Search strategy-we searched MEDLINE, EMBASE, CINAHL (from inception to February 2018), grey literature and reference lists of included studies. (3) Article selection-all published evidence contributing information on the causes of prescribing error in children was eligible for inclusion. We included review articles as secondary evidence to broaden understanding. (4) Charting data-results were collated in a custom data charting form. (5) Reporting results-we summarised article characteristics, extracted causal evidence and thematically synthesised findings. (6) Stakeholder consultation-results were presented to a multidisciplinary focus group of six prescribing stakeholders to establish validity, relevance and mechanisms by which causes lead to errors in practice.

RESULTS

68 articles were included. We identified six main causes of prescribing errors: children's fundamental differences led to individualised dosing and calculations; off-licence prescribing; medication formulations; communication with children; and experience working with children. Primary evidence clarifying causes was lacking.

CONCLUSIONS

Specific factors complicate prescribing for children and increase risk of errors. Primary research is needed to confirm and elaborate these causes of error. In the meantime, this review uses existing evidence to make provisional paediatric-specific recommendations for policy, practice and education.

Medication prescribing errors among hospitalized pediatric patients at Nekemte Referral Hospital, western Ethiopia: cross-sectional study

Objective

Incidence and clinical outcomes of medication prescribing errors are common and potentially more harmful in the pediatric population than in the adult population. Hence, this study was aimed to assess the prevalence and types of medication prescribing errors in the pediatric wards of Nekemte Referral Hospital (NRH).

Results

Of 384 pediatric patients included in the study, 241 (63%) were males and 116 (30.21%) of them were aged between 1–3 years. About 241 (62.76%) of the patients were treated based on empirical diagnosis and only 10 (2.60%) pediatrics had co-morbid disease. The most category of medication prescribing error was dosing error 251 (48.6%) followed by incorrect drug selection 98 (19.0%). Being critically ill (AOR = 5.31, 95% CI = 1.80–12.31, p = 0.003), route of administration via IV (AOR = 3.98, 95% CI = 1.85–11.15, p = 0.011) and via IV + IM route (AOR = 2.22, 95% CI = 1.05–9.25, p = 0.045) as well as 4–6 medications per patient (AOR = 3.10, 95% CI = 3.43–12.42, p = 0.012) and > 6 medications per patient (AOR = 7.23, 95% CI = 3.91–21.45, p < 0.001) were independent predictors of medication prescribing errors. Antibiotics were the most common classes of drugs responsible for prescribing errors.

The Prevalence of Dose Errors Among Paediatric Patients in Hospital Wards with and without Health Information Technology: A Systematic Review and Meta-Analysis

INTRODUCTION

The risk of dose errors is high in paediatric inpatient settings. Computerized provider order entry (CPOE) systems with clinical decision support (CDS) may assist in reducing the risk of dosing errors. Although a frequent type of medication error, the prevalence of dose errors is not well described. Dosing error rates in hospitals with or without CPOE have not been compared.

OBJECTIVE

Our aim was to conduct a systematic review assessing the prevalence and impact of dose errors in paediatric wards with and without CPOE and/or CDS.

METHODS

We systematically searched five databases to identify studies published between January 2000 and December 2017 that assessed dose error rates by medication chart audit or direct observation.

RESULTS

We identified 39 studies, nine of which involved paediatric wards using CPOE with or without CDS. Studies of paediatric wards using paper medication charts reported approximately 8-25% of patients experiencing a dose error, and approximately 2-6% of medication orders and approximately 3-8% of dose administrations contained a dose error, with estimates varying by ward type. The nine studies of paediatric wards using CPOE reported approximately 22% of patients experiencing a dose error, and approximately 1-6% of medication orders and approximately 3-8% of dose administrations contained a dose error. Few studies provided data for individual wards. The severity and prevalence of harm associated with dose errors was rarely assessed and showed inconsistent results.

CONCLUSIONS

Dose errors occur in approximately 1 in 20 medication orders. Hospitals using CPOE with or without CDS had a lower rate of dose errors compared with those using paper charts. However, few pre/post studies have been conducted and none reported a significant reduction in dose error rates associated with the introduction of CPOE. Future research employing controlled designs is needed to determine the true impact of CPOE on dosing errors among children, and any associated patient harm.

Medication errors in hospitals in the Middle East: a systematic review of prevalence, nature, severity and contributory factors

PURPOSE

The aim was to critically appraise, synthesise and present the evidence of medication errors amongst hospitalised patients in Middle Eastern countries, specifically prevalence, nature, severity and contributory factors.

METHODS

CINAHL, Embase, Medline, Pubmed and Science Direct were searched for studies published in English from 2000 to March 2018, with no exclusions. Study selection, quality assessment (using adapted STROBE checklists) and data extraction were conducted independently by two reviewers. A narrative approach to data synthesis was adopted; data related to error causation were synthesised according to Reason's Accident Causation model.

RESULTS

Searching yielded 452 articles, which were reduced to 50 following removal of duplicates and screening of titles, abstracts and full-papers. Studies were largely from Iran, Saudi Arabia, Egypt and Jordan. Thirty-two studies quantified errors; definitions of 'medication error' were inconsistent as were approaches to data collection, severity assessment, outcome measures and analysis. Of 13 studies reporting medication errors per 'total number of medication orders'/ 'number of prescriptions', the median across all studies was 10% (IQR 2-35). Twenty-four studies reported contributory factors leading to errors. Synthesis according to Reason's model identified the most common being active failures, largely slips (10 studies); lapses (9) and mistakes (12); error-provoking conditions, particularly lack of knowledge (13) and insufficient staffing levels (13) and latent conditions, commonly heavy workload (9).

CONCLUSION

There is a need to improve the quality and reporting of studies from Middle Eastern countries. A standardised approach to quantifying medication errors' prevalence, severity, outcomes and contributory factors is warranted.
