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

Development and in vitro evaluation of an infant friendly self-nanoemulsifying drug delivery system (SNEDDS) loaded with an amphotericin B-monoacyl phosphatidylcholine complex for oral delivery

Until relatively recently, the pediatric population has largely been ignored during the development of new drug products, which has led to a high level of "off-label" use of drugs in this particular population. In this study, an infant friendly self-nanoemulsifying drug delivery system (SNEDDS) was developed for oral delivery of a commonly used "off-label" drug - amphotericin B (AmB). AmB was complexed with monoacyl-phosphatidylcholine (MAPC) by lyophilization, transforming crystalline AmB into its amorphous state in the AmB-MAPC complex (APC). The APC-loaded SNEDDS (APC-SNEDDS) showed excellent self-emulsifying properties; after dispersion of the APC-SNEDDS in purified water, nanoscale emulsion droplets were formed within 1 min with a z-average size of 179 ± 1 nm. In vitro pediatric gastrointestinal (GI) digestion and dissolution results showed that the APC-SNEDDS significantly increased the amount of AmB solubilized in aqueous phase and that the precipitated AmB from the APC-SNEDDS re-dissolved faster, compared with crystalline AmB in SNEDDS (AmB-SNEDDS), the complex without the SNEDDS (APC), the physical mixture of AmB and MAPC (AmB/MAPC PM), and crystalline AmB alone (AmB). Overall, the present in vitro results suggest that integrating the APC into an infant friendly SNEDDS is a promising approach for oral delivery of AmB to young pediatric patients.

The epidemiology of drug-related hospital admissions in paediatrics - a systematic review

BACKGROUND

Despite previous efforts, medication safety in paediatrics remains a major concern. To inform improvement strategies and further research especially in outpatient care, we systematically reviewed the literature on the frequency and nature of drug-related hospital admissions in children.

METHODS

Searches covered Embase, Medline, Web of Science, grey literature sources and relevant article citations. Studies reporting epidemiological data on paediatric drug-related hospital admissions published between 01/2000 and 01/2024 were eligible. Study identification, data extraction, and critical appraisal were conducted independently in duplicate using templates based on the 'Joanna Briggs Institute' recommendations.

RESULTS

The review included data from 45 studies reporting > 24,000 hospitalisations for adverse drug events (ADEs) or adverse drug reactions (ADRs). Due to different reference groups, a total of 52 relative frequency values were provided. We stratified these results by study characteristics. As a percentage of inpatients, the highest frequency of drug-related hospitalisation was found with 'intensive ADE monitoring', ranging from 3.1% to 5.8% (5 values), whereas with 'routine ADE monitoring', it ranged from 0.2% to 1.0% (3 values). The relative frequencies of 'ADR-related hospitalisations' ranged from 0.2% to 6.9% for 'intensive monitoring' (23 values) and from 0.04% to 3.8% for 'routine monitoring' (8 values). Per emergency department visits, five relative frequency values ranged from 0.1% to 3.8% in studies with 'intensive ADE monitoring', while all other eight values were ≤ 0.1%. Heterogeneity prevented pooled estimates. Studies rarely reported on the nature of the problems, or studies with broader objectives lacked disaggregated data. Limited data indicated that one in three (median) drug-related admissions could have been prevented, especially by more attentive prescribing. Besides polypharmacy and oncological therapy, no other risk factors could be clearly identified. Insufficient information and a high risk of bias, especially in retrospective and routine observational studies, hampered the assessment.

CONCLUSION

Given the high frequency of drug-related hospitalisations, medication safety in paediatrics needs to be further improved. As routine identification appears unreliable, clinical awareness needs to be raised. To gain more profound insights especially for generating improvement strategies, we have to address under-reporting and methodological issues in future research.

Estimating the impact of label design on reducing the risk of medication errors by applying HEART in drug administration

Medication errors are one of the biggest problems in healthcare. The medicines' poor labelling design (i.e. look-alike labels) is a well-recognised risk for potential confusion, wrong administration, and patient damage. Human factors and ergonomics (HFE) encourages the human-centred design of system elements, which might reduce medication errors and improve people's well-being and system performance.

OBJECTIVE

The aim of the present study is twofold: (i) to use a human reliability analysis technique to evaluate a medication administration task within a simulated scenario of a neonatal intensive care unit (NICU) and (ii) to estimate the impact of a human-centred design (HCD) label in medication administration compared to a look-alike (LA) label.

METHOD

This paper used a modified version of the human error assessment and reduction technique (HEART) to analyse a medication administration task in a simulated NICU scenario. The modified technique involved expert nurses quantifying the likelihood of unreliability of a task and rating the conditions, including medicine labels, which most affect the successful completion of the task.

RESULTS

Findings suggest that error producing conditions (EPCs), such as a shortage of time available for error detection and correction, no independent checking of output, and distractions, might increase human error probability (HEP) in administering medications. Results also showed that the assessed HEP and the relative percentage of contribution to unreliability reduced by more than 40% when the HCD label was evaluated compared to the LA label.

CONCLUSION

Including labelling design based on HFE might help increase human reliability when administering medications under critical conditions.

Understanding the informal aspects of medication processes to maintain patient safety in hospitals: a sociotechnical ethnographic study in paediatric units

Adverse drug events (ADEs) are common in hospitals, affecting one in six child in-patients. Medication processes are complex systems. This study aimed to explore the work-as-done of medication safety in three English paediatric units using direct observation and semi-structured interviews. We found that a combination of the physical environment, traditional work systems and team norms were among the systemic barriers to medicines safety. The layout of wards discouraged teamworking and reinforced professional boundaries. Workspaces were inadequate, and interruptions were uncontrollable. A less experienced workforce undertook prescribing and verification while more experienced nurses undertook administration. Guidelines were inadequate, with actors muddling through together. Formal controls against ADEs included checking (of prescriptions and administration) and barcode administration systems, but these did not integrate into workflows. Families played an important part in the safe administration of medication and provision of information about their children but were isolated from other parts of the system.

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.

Medication Safety Gaps in English Pediatric Inpatient Units: An Exploration Using Work Domain Analysis

OBJECTIVES

Medication is a common cause of preventable medical harm in pediatric inpatients. This study aimed to examine the sociotechnical system surrounding pediatric medicines management, to identify potential gaps in this system and how these might contribute to adverse drug events (ADEs).

METHODS

An exploratory prospective qualitative study in pediatric wards in three hospitals in the north of England was conducted between October 2020 and May 2022. Analysis included a documentary analysis of 72 policies and procedures and analysis of field notes from 60 hours of participant observation. The cognitive work analysis prompt framework was used to generate a work domain analysis (WDA) and identify potential contributory factors to ADEs.

RESULTS

The WDA identified 2 functional purposes, 7 value/priority measures, 6 purpose-related functions, 11 object-related processes and 14 objects. Structured means-ends connections supported identification of 3 potential contributory factors-resource limitations, cognitive demands, and adaptation of processes. The lack of resources (equipment, materials, knowledge, and experience) created an environment where distractions and interruptions were unavoidable. Families helped provide practical support in medicines administration but were largely unacknowledged at an organizational level. There was a lack of teamwork with regards to medication with different professionals responsible for different parts of the system. Mandated safety checks on medicines were frequently omitted because of limited resources and perceived redundancy. Interventions to support adherence to safety policies were also often bypassed because they created more work.

CONCLUSIONS

The WDA has provided insights into the complex system of medication safety for children in hospital and has facilitated the identification of potential contributory factors to ADEs. We therefore advocate (in priority order) for processes to involve parents in the care of their children in hospital, development of skill-mix interventions to ensure appropriate expertise is available where it is needed, and modified checking procedures to permit staff to use their skills and judgment effectively and efficiently.

Medication errors related to high-alert medications in a paediatric university hospital - a cross-sectional study analysing error reporting system data

BACKGROUND

Paediatric patients are prone to medication errors, and only a few studies have explored errors in high-alert medications in children. The present study aimed to investigate the prevalence and nature of medication errors involving high-alert medications and whether high-alert medications are more likely associated with severe patient harm and higher error risk classification compared to other drugs.

METHODS

This study was a cross-sectional report of self-reported medication errors in a paediatric university hospital in 2018-2020. Medication error reports involving high-alert medications were investigated by descriptive quantitative analysis to identify the prevalence of different drugs, Anatomical Therapeutic Chemical groups, administration routes, and the most severe medication errors. Crosstabulation and Pearson Chi-Square (χ2) tests were used to compare the likelihood of more severe consequences to the patient and higher error risk classification between medication errors involving high-alert medications and other drugs.

RESULTS

Among the reported errors (n = 2,132), approximately one-third (34.8%, n = 743) involved high-alert medications (n = 872). The most common Anatomical Therapeutic Chemical subgroups were blood substitutes and perfusion solutions (B05; n = 345/872, 40%), antineoplastic agents (L01; n = 139/872, 16%), and analgesics (N02; n = 98/872, 11%). The majority of high-alert medications were administered intravenously (n = 636/872, 73%). Moreover, IV preparations were administered via off-label routes (n = 52/872, 6%), such as oral, inhalation and intranasal routes. Any degree of harm (minor, moderate or severe) to the patient and the highest risk classifications (IV-V) were more likely to be associated with medication errors involving high-alert medications (n = 743) when compared to reports involving other drugs (n = 1,389).

CONCLUSIONS

Preventive risk management should be targeted on high-alert medications in paediatric hospital settings. In these actions, the use of intravenous drugs, such as parenteral nutrition, concentrated electrolytes, analgesics and antineoplastic agents, and off-label use of medications should be prioritised. Further research on the root causes of medication errors involving high-alert medications and the effectiveness of safeguards is warranted.

Evaluation of nurses' knowledge and performance regarding preparation and injection of intravenous drugs in pediatric wards in Iran

BACKGROUND

A error in intravenous injection in pediatric wards can cause irreparable injuries. This study aimed to determine the level of knowledge and performance of nurses in terms of preparation and injection of intravenous drugs in pediatric wards of hospitals affiliated to Isfahan University of Medical Sciences.

METHODS

This cross-sectional study was conducted in 2022 on 156 nurses working in pediatric wards. The data was collected with demographic information questionnaire and the knowledge and performance of the participants were determined using a researcher-made questionnaire, including the five rights of medication administration (preparation and injection, medication error, drug side effects, family empowerment, and documentation) using self-reporting and observation methods. Formal and content validity was calculated using the opinions of 10 experts and Cronbach's alpha with 40 samples.

RESULTS

The mean and standard deviation of total nurses' knowledge and performance scores were 58.31 + 10.1 and 66.1 + 14.4, respectively. Moreover, the mean and standard deviation of nurses' knowledge scores were 63.55 + 14.3 for documentation, 46.1 + 7.9 for preparation and injection, 73.9 + 12.3 for drug side effects, 58.4 + 10.2 for medication error, and 69.4 + 9.4 for family empowerment. Besides, the mean performance was 69.1 + 17.6 for documentation, 61.3 ± 9.9 for preparation and injection, 78.21 + 12 for drug side effects, 58.6 + 15 for medication error, and 65.4 + 17.7 for family empowerment.

CONCLUSION

The results showed that the mean knowledge and pharmacological performance of nurses working in pediatric wards in different areas of the principles of medicine were not at the desired level, and this can affect children adversely.

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.

Adverse Drug Reactions in Children: Comparison of Reports Collected in a Pharmacovigilance Project Versus Spontaneously Collected ADR Reports

BACKGROUND

Adverse drug reactions (ADRs) and medication errors in children may result from a lack of appropriate drugs, dosages, and pharmaceutical forms. In addition, children may respond differently to drugs than adults. Reporting of ADRs in the pediatric population is therefore of importance in order to increase the amount of safety data. However, different methodological approaches are used to collect ADRs.

OBJECTIVE

The aim of the present study was to analyze whether there were differences in the ADRs collected in the KiDSafe project (845 ADR reports) compared with the spontaneous ADR reports sent to EudraVigilance (697 reports) in the same time period. The strengths and limitations of these two different approaches should be discussed.

METHODS

The same inclusion criteria were applied for the systematically collected ADRs in the KiDSafe project and the spontaneous reports from EudraVigilance, and only reports of ADRs coded with hospitalization were considered. In both datasets, the number of reports (related to number of hospitals), their documentation quality (VigiGrade), causal relationship (World Health Organization-Uppsala Monitoring Centre [WHO-UMC] criteria), most frequently reported drugs and ADRs, demographical parameters of the patients, reported medical histories, and the seriousness of ADR reports were analyzed descriptively. The results of the two analyses were compared.

RESULTS

There was considerable underreporting of ADRs via the spontaneous reports (0.4 reports per hospital; 697/1902) compared with 70.4 reports per hospital (845/12) in the systematically collected KiDSafe reports. Documentation quality assessment yielded similar results in both datasets. Among the 10 most frequently reported drugs, anticonvulsants such as levetiracetam (6.6%), valproic acid (5.6%), oxcarbazepine (3.6%), and lamotrigine (3.4%) were mainly reported in the KiDSafe reports, while in the EudraVigilance reports, mite allergen extract (4.4%) and allergens (3.6%) were preferentially reported. Seizures were the most frequently reported clinically specific ADRs in the KiDSafe reports, whereas anaphylactic reactions and urticaria were prominent in the spontaneous reports from EudraVigilance. Notably, the proportion of reports referring to medication errors and other medication safety related issues were more prominent in KiDSafe than in the spontaneous reports (27.8% vs. 12.6% and 46.0% vs. 29.0%, respectively).

CONCLUSION

In general, reports from both data sources contributed to the identification of ADRs and dedicated issues related to drug therapy. However, these differed by nature and strength of the signal, likely due to the characteristics of the individual method. A combined approach could likely compensate for limitations inherent to the single approaches, but will most likely only be applied to dedicated pharmacovigilance topics or research objectives.

Drug-related risk of hospital readmission in children with chronic diseases, a systematic review

BACKGROUND

Drug-related problems (DRPs) are one of the leading causes of hospital readmissions. Children with chronic diseases are more likely to experience DRPs than adults. The burden and characteristics of drug-related readmissions at and after hospital discharge in children remain unclear.

OBJECTIVE

We aimed to summarize the impact of DRPs at and after hospital discharge on the risk of readmissions in children with chronic diseases.

METHODS

We conducted a systematic review searching PubMed from inception until January 2022. Study selection criteria were studies assessing the impact of different factors at discharge and after discharge on the risk of hospital readmissions in children with chronic diseases, reporting an assessment of DRPs. DRP could be the only risk factor assessed or one among others. Included studies were assessed with the Risk of Bias in Non-Randomized Studies - of Exposure (ROBINS-E) tool. We summarized the qualitative impact of the reported DRPs on hospital readmission as conclusive (significant association) or inconclusive.

RESULTS

Of the 4734 studies initially identified, 13 met inclusion criteria. Eleven studies were retrospective, using electronic health records. The studies assessed the impact of DRPs at or after discharge according to the type of medication (in 6 studies), number of medication (in 5 studies) and medication nonadherence (in 2 studies). From the 44 reported associations between DRPs and the risk of readmission 26 (59% [95% CI, 43%-73%]) were conclusive, of which 81% increased the risk and 19% decreased the risk, and 17 (39% [95% CI, 24%-55%]) were inconclusive.

CONCLUSION

The impact of DRPs on hospital readmissions in children with chronic diseases displayed conflicting results, estimated associations having potentially a serious risk of bias. We need more evidence with a lower risk of bias.

Drug-handling problems and expectations of the ideal pediatric drug-reported by children and their parents

Experienced drug-handling problems and inadequately considered expectations for drug therapy have an unfavorable influence on therapy. We performed a questionnaire survey in (i) parents of 0-5-year-old children and (ii) 6-17-year olds and their parents. We assessed (A) experienced drug-handling problems and (B) expectations for drug therapy. (i) Forty-six parents and (ii) 103 children and their parents participated in the study. Experienced drug-handling problems were described by (i) 100% of parents and (ii) 62% of children and 70% of parents. Problems concerned with the preparation of the drug, dosing, compliance with the time interval, and acceptance. (i) Sixty-five percent of parents preferred a peroral route of drug administration, while (ii) 74% of children and 86% of parents did so. Preferred characteristics of peroral drug formulations, e.g., liquid versus solid drug formulations or flavor, were highly heterogeneous. Preferences of 6-17-year-old children and their parents matched in 43 to 66%.   Conclusion: Most children and their parents had already experienced drug-handling problems. Preferences concerning the ideal pediatric drug were highly heterogeneous and in about half of cases, preferences of children and their parents differed. Thus, the children should be approached directly. If information is solely gained from parents, the children's needs might remain unmet. What is Known: • Pediatric drug administration is complex and therefore error-prone. • Experiences and expectations of children and their parents should be considered. What is New: •Most pediatric patients and their parents have already experienced drug-handling problems. • Expectations concerning the ideal pediatric drug are highly heterogeneous. Parents are often insufficiently aware of those expectations in their children.

Assessment and analysis of outpatient medication errors related to pediatric prescriptions

BACKGROUND

Medication errors are the errors that impact the efficacy and safety of the therapy. The impact of medication errors is higher for certain subjects, such as pediatrics, who require more attention. Hence, the current study aimed to investigate the types and frequency of outpatient medication errors of pediatric subjects related to different prescription types.

METHODS

A cross-sectional study was carried in several community pharmacies to record the medication errors found in outpatient pediatric prescriptions by gathering data from the outpatient prescriptions besides direct counseling with the subjects and their parents. Many medical resources (disease and drug-related) were used for checking the different aspects of medication errors. The data collection process included a preprepared sheet containing several items representing the medication errors in addition to a counseling session. Data were expressed as percentages and compared through the Chi-square test for results of handwritten and computerized prescriptions.

RESULTS

752 outpatient pediatric prescriptions were recruited in the study as they involve medication errors. Among the highest percentage of medication errors was the absence of essential data in the prescription, such as diagnosis, age, and weight. The duration of the therapy and contraindication for some of the prescribed medications were among the highest recorded errors. Among the critical errors were the drug interaction and drug duplication that directly affect the drug's efficacy and safety. There was a significant difference between computerized and handwritten prescriptions regarding the number of medication errors related to each type.

CONCLUSION

Medication errors related to outpatient pediatric prescriptions vary from one to another prescription with predominant errors that influence the therapy's safety or efficacy. The role of patient counseling and prescription checking is critical for improving patient therapy.

Pharmacogenomics: A road ahead for precision medicine in psychiatry

Psychiatric genomics is providing insights into the nature of psychiatric conditions that in time should identify new drug targets and improve patient care. Less attention has been paid to psychiatric pharmacogenomics research, despite its potential to deliver more rapid change in clinical practice and patient outcomes. The pharmacogenomics of treatment response encapsulates both pharmacokinetic ("what the body does to a drug") and pharmacodynamic ("what the drug does to the body") effects. Despite early optimism and substantial research in both these areas, they have to date made little impact on clinical management in psychiatry. A number of bottlenecks have hampered progress, including a lack of large-scale replication studies, inconsistencies in defining valid treatment outcomes across experiments, a failure to routinely incorporate adverse drug reactions and serum metabolite monitoring in study designs, and inadequate investment in the longitudinal data collections required to demonstrate clinical utility. Nonetheless, advances in genomics and health informatics present distinct opportunities for psychiatric pharmacogenomics to enter a new and productive phase of research discovery and translation.

"Childrens are not just "little adults". The rate of medication related problems and its predictors among patients admitted to pediatric ward of southwestern Ethiopian hospital: A prospective observational study

Background

The rate of medication related problems is high in developing countries due to the complexity of pediatrics medication management. Pediatric population should have their own dosage regimens. The pediatric dosage regimens were derived from the adult dose that might lead to sudden reach of sub or supra-therapeutic doses. As the result, the medication therapy management is difficult in this populations. Despite this, a scanty of studies were conducted on medication related problems among pediatric populations. Therefore, this study examined the prevalence and risk factors for the occurrence of the medication related problems among patients admitted to pediatric ward of Mettu karl referral hospital.

Patients and methods

The pediatric population who were received the pharmacotherapy for their disease was observed and followed for the occurrences of medication related problems at pediatric wards of Mettu karl referral hospital from February 12, 2020 to February 24, 2021. Patients whose age was less than or equal to 18 years and who were on drug therapy or who needs drug therapy during study period were included. The possibility of adverse drug reactions developed from the drug was assessed by using the Naranjo scale. Multivariable logistic regression analysis was used to determine the predictors of medication related problems.

Result

Over the study period, a total of 189 pediatric populations were included. Among these, 115 (60.8%) were males, and the mean age of the patients was 1.4339 ± 0.864 years. The mediciation related problems was found among 121(64.01%) of pediatric patients. Among seven types of drug therapy problems unnecessary drug therapy, need additional drug therapy, ineffective drug therapy and dose too high were the most predominantly occured DRP that accounted 74 (27.72%), 67 (25.09%), 43 (16.10%), 36 (13.48%), respectively. The mean number of hospital stay was 4.29 days with minimum and maximum stay of 2 and 9 days and antibiotics 364(51.3%) were the most common class of drugs that was associated with drug related problems. Being a neonate (AOR = 1.48, 95CI%: 1.69–7.42, P = <0.001), hospital stay greater than or equal to seven days (AOR = 1.98, 95CI%: 2.471–12.644, P = 0.016), and the presence of co-morbidity(AOR = 2.507, 95CI%: 3.270–4.949, P = 0.080) were the predictors of the medication related problems.

Conclusion

The prevalence of medication-related problems in pediatrics patient was found to be high. Being neonatal, prolonged hospital stay and the presence of a multiple disease were the predictors of medication-related problems in pediatric patients. Therefore special attention should be given for newborns, prolonged hospital stay and patients having co-morbidity. Besides this, the drug information service and the patients round activity should be started by clinical pharmacist to decrease the occurences of any preventable medication related problems.

Interventions to Reduce Pediatric Prescribing Errors in Professional Healthcare Settings: A Systematic Review of the Last Decade

INTRODUCTION

Pediatric medication therapy is prone to errors due to the need for pharmacokinetic and pharmacodynamic individualization and the diverse settings in which pediatric patients are treated. Prescribing errors have been reported as the most common medication error.

OBJECTIVES

The aim of this review was to systematically identify interventions to reduce prescribing errors and corresponding patient harm in pediatric healthcare settings and to evaluate their impact.

METHODS

Four databases were systematically screened (time range November 2011 to December 2019), and experimental studies were included. Interventions to reduce prescribing errors were extracted and classified according to a 'hierarchy of controls' model.

RESULTS

Forty-five studies were included, and 70 individual interventions were identified. A bundle of interventions was more likely to reduce prescribing errors than a single intervention. Interventions classified as 'substitution or engineering controls' were more likely to reduce errors in comparison with 'administrative controls', as is expected from the hierarchy of controls model. Fourteen interventions were classified as substitution or engineering controls, including computerized physician order entry (CPOE) and clinical decision support (CDS) systems. Administrative controls, including education, expert consultations, and guidelines, were more commonly identified than higher level controls, although they may be less likely to reduce errors. Of the administrative controls, expert consultations were most likely to reduce errors.

CONCLUSIONS

Interventions to reduce pediatric prescribing errors are more likely to be successful when implemented as part of a bundle of interventions. Interventions including CPOE and CDS that substitute risks or provide engineering controls should be prioritized and implemented with appropriate administrative controls including expert consultation.

Model Based Evaluation of Hypersensitivity Adverse Drug Reactions to Antimicrobial Agents in Children

Drug use in children is-in most cases-supported by extrapolation of data generated from clinical trials in adult populations. This puts children at higher risk of developing adverse drug reactions (ADRs) due to "off-label" use of drugs and dosing issues. Major types of ADRs are drug hypersensitivity reactions, an idiosyncratic type of ADRs that are largely unpredictable and can cause high morbidity and mortality in a hard-to-identify specific population of patients. Lack of a complete understanding of the pathophysiology of DHRs and their unpredictive nature make them problematic in clinical practice and in drug development. In addition, ethical and legal obstacles hinder conducting large clinical trials in children, which in turn make children a "therapeutic orphan" where clear clinical guidelines are lacking, and practice is based largely on the personal experience of the clinician, hence making modeling desirable. This brief review summarizes the current knowledge of model-based evaluation of diagnosis and management of drug hypersensitivity reactions (DHRs) to antimicrobial drugs in the pediatric population. Ethical and legal aspects of drug research in children and the effect of different stages of child development and other factors on the risk of DHRs are discussed. The role of animal models, in vitro models and oral provocation test in management of DHRs are examined in the context of the current understanding of the pathophysiology of DHRs. Finally, recent changes in drug development legislations have been put forward to encourage drug developers to conduct trials in children clearly indicate the urgent need for evidence to support drug safety in children and for modeling to guide these clinical trials.

Associations between double-checking and medication administration errors: a direct observational study of paediatric inpatients

BACKGROUND

Double-checking the administration of medications has been standard practice in paediatric hospitals around the world for decades. While the practice is widespread, evidence of its effectiveness in reducing errors or harm is scarce.

OBJECTIVES

To measure the association between double-checking, and the occurrence and potential severity of medication administration errors (MAEs); check duration; and factors associated with double-checking adherence.

METHODS

Direct observational study of 298 nurses, administering 5140 medication doses to 1523 patients, across nine wards, in a paediatric hospital. Independent observers recorded details of administrations and double-checking (independent; primed-one nurse shares information which may influence the checking nurse; incomplete; or none) in real time during weekdays and weekends between 07:00 and 22:00. Observational medication data were compared with patients' medical records by a reviewer (blinded to checking-status), to identify MAEs. MAEs were rated for potential severity. Observations included administrations where double-checking was mandated, or optional. Multivariable regression examined the association between double-checking, MAEs and potential severity; and factors associated with policy adherence.

RESULTS

For 3563 administrations double-checking was mandated. Of these, 36 (1·0%) received independent double-checks, 3296 (92·5%) primed and 231 (6·5%) no/incomplete double-checks. For 1577 administrations double-checking was not mandatory, but in 26·3% (n=416) nurses chose to double-check. Where double-checking was mandated there was no significant association between double-checking and MAEs (OR 0·89 (0·65-1·21); p=0·44), or potential MAE severity (OR 0·86 (0·65-1·15); p=0·31). Where double-checking was not mandated, but performed, MAEs were less likely to occur (OR 0·71 (0·54-0·95); p=0·02) and had lower potential severity (OR 0·75 (0·57-0·99); p=0·04). Each double-check took an average of 6·4 min (107 hours/1000 administrations).

CONCLUSIONS

Compliance with mandated double-checking was very high, but rarely independent. Primed double-checking was highly prevalent but compared with single-checking conferred no benefit in terms of reduced errors or severity. Our findings raise questions about if, when and how double-checking policies deliver safety benefits and warrant the considerable resource investments required in modern clinical settings.

Drug related problems in clinical practice: a cross-sectional study on their prevalence, risk factors and associated pharmaceutical interventions

Drug-related problems (DRP) cause preventable negative health outcomes, especially during hospital admissions. The aim of our study was to examine the prevalence and characteristics of DRP in regular clinical pharmacy, as well as to determine those factors associated with a higher risk of DRP in the hospital setting. We analyzed data from a standardized registry database of regular pharmacy practice (2015- 2016). DRP were classified according to the Pharmaceutical Care Network Europe v6.2 classification. Cross-sectional data were obtained from 1602 adults admitted to medical wards. Crude and adjusted binary logistic regressions were performed to identify associations between potential risk factors and DRP. Overall DRP prevalence was high across medical specialties (45,1%), in a population characterized by advanced age, polypharmacy and multimorbidity. Problems leading to DRP were mainly classified into two domains (effectiveness and adverse reactions), being drug and dose selection the most frequent causes. Interventions were accepted and DRP were totally or partially solved in 74.1% and 4.81% of cases, respectively. In the adjusted model polypharmacy, allergies, BMI > 25 kg/m2 and clearance < 30 mL/min were associated with a higher risk of DRP. The participation of clinical pharmacists into multidisciplinary teams promotes the detection and solution of DRP. Polypharmacy, obesity, renal impairment and allergy are associated with a higher risk of DRP during admission.

Establishing dose bands for commonly prescribed oral medications for children in the UK: Results of a Delphi study

OBJECTIVE

To establish weight-based dose bands for commonly used oral medicines, given in liquid forms, for children in the UK that could be used for prescribing and administering accurate and safe drug doses.

METHODS

A list of commonly prescribed, oral liquid medications was established from the medication dispensing database of four UK hospitals and a primary care database. The evidence base of currently used dose regimens for each drug was identified from paediatric reference books, summary of product characteristics and the literature. Then, weight-based dose bands were developed and a modified Delphi process was used to achieve healthcare professional consensus about the suggested dose bands for each drug.

RESULTS

Forty-six experts in paediatric medicines participated in the Delphi process (mean years of experience 17.3 ± 9.4 [standard deviation]) and assessed 45 oral liquid drugs in total. Four categories of weight-based dose bands were established: drugs with two dose bands (17.8%, 8/45), drugs with three dose bands (64.4%, 29/45), drugs with four dose bands (15.6%, 7/45) and drugs with five dose bands (2.2%, 1/45). The 46 participants reached consensus on all the suggested dose bands for 53.3% (24/45) of the drugs. Consensus was reached in the first round of the Delphi process for 91.7% (22/24) of the drugs and after two rounds for two drugs. No agreement was achieved on any of the suggested dose bands for 26.7% (12/45) of the drugs.

CONCLUSION

This study provides healthcare professionals with a set of recommended weight-based dose bands for commonly prescribed oral liquid drugs for children. These bands could establish the basis for change in clinical practice to reduce dosing errors and improve healthcare for children.

Interventions to Reduce Medication Dispensing, Administration, and Monitoring Errors in Pediatric Professional Healthcare Settings: A Systematic Review

Introduction: Pediatric patients cared for in professional healthcare settings are at high risk of medication errors. Interventions to improve patient safety often focus on prescribing; however, the subsequent stages in the medication use process (dispensing, drug administration, and monitoring) are also error-prone. This systematic review aims to identify and analyze interventions to reduce dispensing, drug administration, and monitoring errors in professional pediatric healthcare settings. Methods: Four databases were searched for experimental studies with separate control and intervention groups, published in English between 2011 and 2019. Interventions were classified for the first time in pediatric medication safety according to the "hierarchy of controls" model, which predicts that interventions at higher levels are more likely to bring about change. Higher-level interventions aim to reduce risks through elimination, substitution, or engineering controls. Examples of these include the introduction of smart pumps instead of standard pumps (a substitution control) and the introduction of mandatory barcode scanning for drug administration (an engineering control). Administrative controls such as guidelines, warning signs, and educational approaches are lower on the hierarchy and therefore predicted by this model to be less likely to be successful. Results: Twenty studies met the inclusion criteria, including 1 study of dispensing errors, 7 studies of drug administration errors, and 12 studies targeting multiple steps of the medication use process. A total of 44 interventions were identified. Eleven of these were considered higher-level controls (four substitution and seven engineering controls). The majority of interventions (n = 33) were considered "administrative controls" indicating a potential reliance on these measures. Studies that implemented higher-level controls were observed to be more likely to reduce errors, confirming that the hierarchy of controls model may be useful in this setting. Heterogeneous study methods, definitions, and outcome measures meant that a meta-analysis was not appropriate. Conclusions: When designing interventions to reduce pediatric dispensing, drug administration, and monitoring errors, the hierarchy of controls model should be considered, with a focus placed on the introduction of higher-level controls, which may be more likely to reduce errors than the administrative controls often seen in practice.

[Improving the Safety of Drug Therapy through a Hospital-Internal Reporting System - Analysis of Reports over 15 Years from a Children's Hospital]

BACKGROUND

Patient safety is a major challenge and has high priority in the inpatient care. Notably, drug therapy is considered critical after surgery. The medication process is particularly difficult and problematic in newborns and children.

METHOD

 In a retrospective analysis, hospital-internal spontaneous reports on Drug-related Problems (DRP) from a children's hospital were analysed, which were reported between 2000 and 2014.

RESULTS

229 spontaneous reports on DRP were considered for analysis. 72.5% of these were due to a Medication Error. Nearly half of the DRP occurred during drug dispensing (44.5%), followed by problems during administration (38.0%) and prescribing (11.4%). 61.4% of Medication Errors were dispensing errors (esp. confusion of patients, wrong dose). Almost all Other Incidents happened during drug administration (mainly extravasations). 40.6% of DRP reports were associated with clinically relevant patient harm and occurred particularly during drug administration.

CONCLUSION

These results show that drug therapy in paediatrics is a complex and hazardous process. The system of hospital-internal spontaneous reports has led to regular training and raising awareness of the employees for critical situations. In addition, it fosters a safety culture to report mistakes. Spontaneous reporting is suitable for increasing the safety of drug therapy in paediatrics.

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.
