What is the epidemiology of medication errors, error-related adverse events and risk factors for errors in adults managed in community care contexts? A systematic review of the international literature.

ABSTRACT:

Objective

To investigate the epidemiology of medication errors and error-related adverse events in adults in primary care, ambulatory care and patients' homes.

Design

Systematic review.

Data source

Six international databases were searched for publications between 1 January 2006 and 31 December 2015.

Data extraction and analysis

Two researchers independently extracted data from eligible studies and assessed the quality of these using established instruments. Synthesis of data was informed by an appreciation of the medicines' management process and the conceptual framework from the International Classification for Patient Safety.

Results

60 studies met the inclusion criteria, of which 53 studies focused on medication errors, 3 on error-related adverse events and 4 on risk factors only. The prevalence of prescribing errors was reported in 46 studies: prevalence estimates ranged widely from 2% to 94%. Inappropriate prescribing was the most common type of error reported. Only one study reported the prevalence of monitoring errors, finding that incomplete therapeutic/safety laboratory-test monitoring occurred in 73% of patients. The incidence of preventable adverse drug events (ADEs) was estimated as 15/1000 person-years, the prevalence of drug-drug interaction-related adverse drug reactions as 7% and the prevalence of preventable ADE as 0.4%. A number of patient, healthcare professional and medication-related risk factors were identified, including the number of medications used by the patient, increased patient age, the number of comorbidities, use of anticoagulants, cases where more than one physician was involved in patients' care and care being provided by family physicians/general practitioners.

Conclusion

A very wide variation in the medication error and error-related adverse events rates is reported in the studies, this reflecting heterogeneity in the populations studied, study designs employed and outcomes evaluated. This review has identified important limitations and discrepancies in the methodologies used and gaps in the literature on the epidemiology and outcomes of medication errors in community settings.

Project description:BackgroundMedication errors and adverse drug events are universal problems contributing to patient harm but the magnitude of these problems in Africa remains unclear.ObjectiveThe objective of this study was to systematically investigate the literature on the extent of medication errors and adverse drug events, and the factors contributing to medication errors in African hospitals.MethodsWe searched PubMed, MEDLINE, EMBASE, Web of Science and Global Health databases from inception to 31 August, 2017 and hand searched the reference lists of included studies. Original research studies of any design published in English that investigated adverse drug events and/or medication errors in any patient population in the hospital setting in Africa were included. Descriptive statistics including median and interquartile range were presented.ResultsFifty-one studies were included; of these, 33 focused on medication errors, 15 on adverse drug events, and three studies focused on medication errors and adverse drug events. These studies were conducted in nine (of the 54) African countries. In any patient population, the median (interquartile range) percentage of patients reported to have experienced any suspected adverse drug event at hospital admission was 8.4% (4.5-20.1%), while adverse drug events causing admission were reported in 2.8% (0.7-6.4%) of patients but it was reported that a median of 43.5% (20.0-47.0%) of the adverse drug events were deemed preventable. Similarly, the median mortality rate attributed to adverse drug events was reported to be 0.1% (interquartile range 0.0-0.3%). The most commonly reported types of medication errors were prescribing errors, occurring in a median of 57.4% (interquartile range 22.8-72.8%) of all prescriptions and a median of 15.5% (interquartile range 7.5-50.6%) of the prescriptions evaluated had dosing problems. Major contributing factors for medication errors reported in these studies were individual practitioner factors (e.g. fatigue and inadequate knowledge/training) and environmental factors, such as workplace distraction and high workload.ConclusionMedication errors in the African healthcare setting are relatively common, and the impact of adverse drug events is substantial but many are preventable. This review supports the design and implementation of preventative strategies targeting the most likely contributing factors.

Project description:BackgroundIncreasing numbers of older people are receiving support with medicines management from community nursing services (CNSs) to enable them to live in their own homes. Little is known about these people and the support they receive.ObjectivesTo explore the characteristics of older people referred for medicines management support, type of support provided, medication errors and adverse medication events (AMEs).MethodsA retrospective observational study of a random sample of 100 older people referred to a large non-profit CNS for medicines management support over a 3-month period was conducted. Measures were: demographics, referral source, current medical problems, medicines, medication aids, types of medication authorisations used by nurses, frequency of nurse visits and type of support provided, medication errors, AMEs and interdisciplinary teamwork among community nurses, general practitioners and pharmacists.ResultsOlder people (median 80 years) were referred for medicines support most often by hospitals (39 %). Other referrals were from families/carers, case-managers, palliative care services and general practitioners. Multiple health conditions (median 5) and medicines (median 10) were common; 66 % used ≥5 medicines; 48 % used ≥1 high-risk medicines-most commonly opiates, anticoagulants and insulin. Medication aids were frequently used, mostly multi-compartment dose administration aids (47 %). Most people received regular community nurse visits (≥4 per week) to administer medicines or monitor medicine-taking. Only 16 % had a medication administration chart; for other clients nurses used medicine lists or letters from doctors for medication authorisation. Medication errors occurred in 41 % of people and 13 % had ≥1 AME requiring medical consultation or hospitalisation; 9/13 (64 %) AMEs were potentially preventable. There was little evidence of interdisciplinary teamwork or medication review.ConclusionCNS clients had multiple risk-factors for medication misadventure. Deficiencies in medicines management were identified, including low use of medication charts and interdisciplinary medication review. Strategies are needed to improve medicines management in the home-care setting.

Project description:BackgroundInitiation and up-titration of guideline-directed medical therapies (GDMTs) for heart failure with reduced ejection fraction (HFrEF) remains suboptimal, in part because of concerns regarding tolerability and adverse events (AEs).ObjectivesThe authors sought to compare rates of AE in patients randomized to GDMT medication vs placebo in a meta-analysis of landmark cardiovascular outcomes trials.MethodsThe authors assessed rates of reported AE in 17 landmark HFrEF clinical trials across each class of GDMT in the placebo and intervention arms. The overall rates of AE for each drug class, the absolute difference in frequency in AEs between the placebo and intervention arms, and the odds of each AE according based on randomization strata were calculated.ResultsAE were reported commonly in trials across each class of GDMT, with 75% to 85% of participants reporting at least 1 AE. There was no significant difference in the frequency of AE between the intervention and placebo arms, except for angiotensin-converting enzyme inhibitors (87.0% [95% CI: 85.0%-88.8%] vs 82.0% [95% CI: 79.8%-84.0%], absolute difference: +5% with intervention; P < 0.001). There was no significant difference in drug discontinuation because of AE between placebo and intervention arms in angiotensin-converting enzyme inhibitors, mineralocorticoid receptor antagonists, sodium glucose cotransporter 2 inhibitors, or angiotensin receptor neprilysin inhibitor/angiotensin II receptor blocker trials. Patients randomized to beta-blocker were significantly less likely to stop study drug because of AE than placebo (11.3% [95% CI: 10.3%-12.3%] vs 13.7% [95% CI: 12.5%-14.9%], absolute difference: -1.1%; P = 0.015). When individual types of AE were assessed, the initiation of an intervention vs placebo resulted in small differences in absolute frequency of AE that were largely not statistically significant.ConclusionsIn clinical trials of GDMT for HFrEF, AEs are observed frequently. However, rates of AE are similar between active medication and control, suggesting these may reflect the high risk nature of the heart failure disease state rather than be attributive to a specific therapy.

Project description:IntroductionChildren admitted to paediatric and neonatal intensive care units may be at high risk from medication errors and preventable adverse drug events.ObjectiveThe 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 sourcesSeven electronic databases were searched between January 2000 and March 2019.Study selectionQuantitative 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 extractionData on study design, detection method used, rates and types of medication errors/preventable adverse drug events, and medication classes involved were extracted.ResultsThirty-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.ConclusionsMedication 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.

Project description:BackgroundIt is estimated that 237 million medication errors occur in England each year with a significant number occurring in the community. Our understanding of the causes of preventable medication errors and adverse drug events (ADE) affecting patients with mental illness is limited in this setting. Better understanding of the factors that contribute to errors can support the development of theory-driven improvement interventions.MethodsRemote qualitative semi-structured interviews with 26 community-based healthcare professionals in England and Wales were undertaken between June-November 2022. Recruitment was undertaken using purposive sampling via professional networks. Interviews were guided by the critical incident technique and analysed using the framework method. Any data that involved speculation was not included in the analysis. Independent analysis was carried out by the research team to extract themes guided by the London Protocol.ResultsA total of 43 medication errors and 12 preventable ADEs were discussed, with two ADEs having an unknown error origin. Prescribing errors were discussed most commonly (n = 24), followed by monitoring errors (n = 8). Six contributory factor themes were identified: the individual (staff); the work environment; the teams/interfaces; the organisation and management; the patient; and the task and technology. The individual (staff) factors were involved in just over 80% of all errors discussed. Participants reported a lack of knowledge regarding psychotropic medication and mental illnesses which accompanied diffusion of responsibility. There were difficulties with team communication, particularly across care interfaces, such as ambiguity/brevity of information being communicated and uncertainty concerning roles which created confusion amongst staff. Unique patient social/behavioural contributory factors were identified such as presenting with challenging behaviour and complex lifestyles, which caused difficulties attending appointments as well as affecting overall clinical management.ConclusionThese findings highlight that the causes of errors are multifactorial with some unique to this patient group. Key areas to target for improvement include the education/training of healthcare professionals regarding neuropharmacology/mental illnesses and enhancing communication across care interfaces. Future research should explore patient perspectives regarding this topic to help develop a holistic picture. These findings can be used to guide future intervention research to ameliorate medication safety challenges for this patient group.

Project description:In 2011, an estimated 26.8 million US adults used prescription medications for mental illness.To estimate the numbers and rates of adverse drug event (ADE) emergency department (ED) visits involving psychiatric medications among US adults between January 1, 2009, and December 31, 2011.Descriptive analyses of active, nationally representative surveillance of ADE ED visits using the National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance system and of drug prescribing during outpatient visits using the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey.Medical records from national probability samples of ED and outpatient visits by adults 19 years or older were reviewed and analyzed.Antidepressants, antipsychotics, lithium salts, sedatives and anxiolytics, and stimulants.National estimates of ADE ED visits resulting from therapeutic psychiatric medication use and of psychiatric medication ADE ED visits per 10,000 outpatient visits at which psychiatric medications were prescribed.From 2009 through 2011, there were an estimated 89,094 (95% CI, 68,641-109,548) psychiatric medication ADE ED visits annually, with 19.3% (95% CI, 16.3%-22.2%) resulting in hospitalization and 49.4% (95% CI, 46.5%-52.4%) involving patients aged 19 to 44 years. Sedatives and anxiolytics, antidepressants, antipsychotics, lithium salts, and stimulants were implicated in an estimated 30,707 (95% CI, 23,406-38,008), 25,377 (95% CI, 19,051-31,704), 21,578 (95% CI, 16,599-26,557), 3620 (95% CI, 2311-4928), and 2779 (95% CI, 1764-3794) respective ADE ED visits annually. Antipsychotics and lithium salts were implicated in 11.7 (95% CI, 10.1-13.2) and 16.4 (95% CI, 13.0-19.9) ADE ED visits per 10,000 outpatient prescription visits, respectively, compared with 3.6 (95% CI, 3.2-4.1) for sedatives and anxiolytics, 2.9 (95% CI, 2.3-3.5) for stimulants, and 2.4 (95% CI, 2.1-2.7) for antidepressants. The commonly used sedative zolpidem tartrate was implicated in 11.5% (95% CI, 9.5%-13.4%) of all adult psychiatric medication ADE ED visits and in 21.0% (95% CI, 16.3%-25.7%) of visits involving adults 65 years or older, in both cases significantly more than any other psychiatric medication.Psychiatric medications are implicated in many ADEs treated in US EDs. Efforts to reduce ADEs should include adults of all ages but might prioritize medications causing high numbers and rates of ED visits.

Project description:BackgroundThe Health Information Technology for Economic and Clinical Health (HITECH) Act subsidizes implementation by hospitals of electronic health records with computerized provider order entry (CPOE), which may reduce patient injuries caused by medication errors (preventable adverse drug events, pADEs). Effects on pADEs have not been rigorously quantified, and effects on medication errors have been variable. The objectives of this analysis were to assess the effectiveness of CPOE at reducing pADEs in hospital-related settings, and examine reasons for heterogeneous effects on medication errors.MethodsArticles were identified using MEDLINE, Cochrane Library, Econlit, web-based databases, and bibliographies of previous systematic reviews (September 2013). Eligible studies compared CPOE with paper-order entry in acute care hospitals, and examined diverse pADEs or medication errors. Studies on children or with limited event-detection methods were excluded. Two investigators extracted data on events and factors potentially associated with effectiveness. We used random effects models to pool data.ResultsSixteen studies addressing medication errors met pooling criteria; six also addressed pADEs. Thirteen studies used pre-post designs. Compared with paper-order entry, CPOE was associated with half as many pADEs (pooled risk ratio (RR)?=?0.47, 95% CI 0.31 to 0.71) and medication errors (RR?=?0.46, 95% CI 0.35 to 0.60). Regarding reasons for heterogeneous effects on medication errors, five intervention factors and two contextual factors were sufficiently reported to support subgroup analyses or meta-regression. Differences between commercial versus homegrown systems, presence and sophistication of clinical decision support, hospital-wide versus limited implementation, and US versus non-US studies were not significant, nor was timing of publication. Higher baseline rates of medication errors predicted greater reductions (P?<?0.001). Other context and implementation variables were seldom reported.ConclusionsIn hospital-related settings, implementing CPOE is associated with a greater than 50% decline in pADEs, although the studies used weak designs. Decreases in medication errors are similar and robust to variations in important aspects of intervention design and context. This suggests that CPOE implementation, as subsidized under the HITECH Act, may benefit public health. More detailed reporting of the context and process of implementation could shed light on factors associated with greater effectiveness.
