The incidence of adverse events and medical error in pediatrics

Incidence of Hospital-Acquired Conditions During Pediatric Clinical Research Inpatient Hospitalizations: A Matched Cohort Study

OBJECTIVES

In this matched cohort study using data from pediatric hospitals, we compared the incidence of hospital-acquired conditions (HACs) during clinical research hospitalizations to nonresearch hospitalizations.

METHODS

Using Pediatric Health Information System data for inpatient discharges January 2017-June 2022, we matched research hospitalizations (identified by International Classification of Diseases, Tenth Revision, diagnosis code) to nonresearch hospitalizations within hospital on age (±3 y), sex, discharge year (±2), and All Patients Refined Diagnosis Related Groups classification, severity of illness (±1), and risk of mortality (±1). We calculated the incidence (per 1000 discharges) and incidence rate (per 10,000 patient days) of HAC identified by International Classification of Diseases, Tenth Revision, codes and compare research versus nonresearch using logistic and Poisson regression, accounting for matching using generalized estimating equations and adjusting for sociodemographic factors and hospital utilization.

RESULTS

We matched 7000 research hospitalizations to 26,447 nonresearch from 28 hospitals. Median age was 6.0 years (interquartile range, 10.6 y). Median length of stay was 4.0 days (interquartile range, 11.0 days) with longer stays among research hospitalizations ( P < 0.001). Incidence of HAC among research hospitalizations was 13.1 versus 7.2 per 1000 for nonresearch ( P < 0.001) and incidence rate 6.7 versus 4.5 per 10,000 patient days. Adjusting for sociodemographic and clinical factors, research stays had 1.65 times the odds of any HAC (95% confidence interval, 1.27-2.16; P < 0.001) and 1.38 times the incidence rate (95% confidence interval, 1.09-1.75; P = 0.009).

CONCLUSIONS

Our findings indicate that pediatric research hospitalizations are more likely to experience HACs compared with nonresearch hospitalizations. These findings have important safety implications for pediatric inpatient clinical research that warrant further study.

Paediatric harmful adverse drug events (PHADE)

Background and Objectives

It is well established that adverse drug events are frequent in paediatric hospital practice. The objective of this study is to systematically quantify and report the incidence of harmful adverse drug events across our institution and to identify predominant medications and error types.

Methods

We prospectively compiled a validated medication safety database for paediatric inpatients within our institution over a three-and-a-half-year period. All incidences of apparent patient harm relating to medication error were investigated and analyzed to determine veracity, severity of harm, phase of medication process, error type, causative medication, and contributory factors enabling each event.

Results

We identified 59 harmful adverse drug events, with an overall rate of 15.5 per 105 patient bed days. Most events occurred during administration (n = 27) and prescribing (n = 26) phases. Almost half of all harm (49%) was associated with opioids; a broad range of medication classes accounted for other harm. Harmful events occurred in 7.3 per 105 administrations of morphine and 13.3 per 105 administrations of hydromorphone. Wrong dose was the most frequently encountered error type.

Conclusions

This is the first study to quantify harmful adverse drug events in paediatric hospital practice. Our prospective analysis and compilation of harmful medication errors in paediatric hospital practice, reported with denominators of opioid administrations, and patient bed days, is a new standard for comparison in the long-discussed problem of paediatric harmful adverse drug events. By focusing on identified problematic drugs, error types, and contributory factors, we identify opportunities for interventions, error prevention and harm reduction.

Global Assessment of Pediatric Patient Safety Tool for identifying safety incidents in pediatric patients

OBJECTIVE

The aim of this study was to evaluate the accuracy of the Global Assessment of Pediatric Patient Safety (GAPPS) in order to identify patient safety incidents with patient harm or adverse events (AEs).

METHODS

This is a cross-sectional, retrospective study of 240 records of hospitalized patients of both genders under 18 years of age, systematically and randomly selecting 10 charts of patients that meet the GAPPS criteria every 15 days from the 4,041 records of 2017.

RESULTS

The prevalence of AEs was 12.5%, i.e., detected in 30 out of 240 medical records. In total, 53 AEs and 63 harm were recorded, of which 53 (84.1%) were temporary and 43 AE (68.2%) were definitely or probably preventable. The presence of at least one trigger in a medical chart revealed 13 times greater chance of the occurrence of an AE, with sensitivity index of 48.5%, specificity of 100%, and accuracy of 86.5%.

CONCLUSION

GAPPS was effective in detecting patient safety incidents with harm or AE.

Liver enzymes after short-term acetaminophen error in critically ill children: a cohort study

Drug-associated harm is common but difficult to detect in the hospital setting. In critically ill children, we sought to evaluate drug-associated hepatic injury following enteral acetaminophen error, defined as acetaminophen dosing that exceeds daily maximum recommendations. This retrospective cohort study took place in two pediatric intensive care units within a pediatric hospital center. The included patients are children (< 18 years of age) admitted to the pediatric and cardiac intensive care unit between January 2008 and January 2018, and receiving enteral acetaminophen. We defined acetaminophen dosing error as exceeding daily acetaminophen dosing by > 10% the upper limit of maximum recommended dose for weight and age (> 82.5 mg/kg/day or > 4400 mg/day). We included 14,146 admissions, who received 147,485 doses of acetaminophen. Acetaminophen dosing errors occurred 1 in every 9.5 patient-days on acetaminophen. ALT and AST decreased significantly over the course of ICU admission (p < 0.0001). In patients with acetaminophen errors, ALT and AST measured in the 24 to 96 h post error were not significantly different than when measured outside this window. A sensitivity analysis using > 100 mg/kg/day as the upper daily acetaminophen error cut-off did not reveal any subsequent significant increase in ALT or ALT in the 24 to 96-h post-error window, compared to measurements taken outside the window.

CONCLUSION

Although the administration of acetaminophen in critically ill children frequently exceeds the daily recommended limit and vigilance is needed, we did not find any associated increase in liver transaminases following acetaminophen errors.

WHAT IS KNOWN

• Acetaminophen dosing errors are common in pediatric outpatients. • Excessive acetaminophen dosing can be associated with harm, including hepatic injury.

WHAT IS NEW

• Exceeding daily acetaminophen dosing limit occurs 1 in every 9.5 patient-days in children admitted to the critical care unit. • In patients with daily dose excess of acetaminophen, we did not find a significant increase in the measured liver enzymes in the 24 to 96 h following the overdosing.

The Effect of Personal Protective Equipment Use on Nurses' Tendencies to Make Medical Errors and Types of Their Medical Errors: A Cross-Sectional Study

This study was conducted to determine the effect of nurses' use of Personal Protective Equipment (PPE) during their care practices on their tendency to make medical errors and types of medical errors. The study was conducted with 505 nurses in Turkey between May 2021 and June 2021. Descriptive statistics, Kruskal-Wallis H test, Spearman's correlation test, and Mann-Whitney U test were used to analyze the data. During the COVID-19 pandemic, nurses often used PPE on different levels. A significant relationship was determined between the type of PPE used by the nurses and falls, hospital infections and patient monitoring/material safety (p < 0.05). The conclusions in this study reveal the necessity of increasing the usability, safety and effectiveness of PPE used by nurses in health institutions.

Multi-incident analysis of reviews of serious adverse clinical events in children with serious bacterial infection and/or sepsis in Queensland, Australia between 2012 and 2017

AIM

To report on findings from a multi-incident analysis of reviews of serious paediatric adverse clinical events related to serious bacterial infection and/or sepsis (hereafter referred to as sepsis for brevity) in Queensland, Australia, between 2012 and 2017.

METHODS

The Queensland Paediatric Quality Council reviewed documentation from reviews of serious adverse events occurring in children (<18 years) with a diagnosis of sepsis at Queensland public hospitals between 2012 and 2017, including clinical details, coronial reports, autopsy reports and root cause analysis documents. A multi-incident tool was designed and used by an expert panel to identify patient and facility demographics, contributing factors, and human and system factors associated with paediatric serious adverse events.

RESULTS

There were 28 serious adverse clinical events reported related to paediatric sepsis, characterised by a high proportion of deaths (23) and a predominance of children aged under 4 years. Approximately half of all facilities were classified as rural and remote health services. Contributing factors included difficulty in recognising and responding to the deteriorating patient, inadequate management/treatment, diagnostic error (mainly diagnostic delay) and escalation delay/failure. Major system factors included communication issues, incorrect use of the early warning tool, inadequate coordination of care planning, policy/protocol/guideline failures and workforce problems.

CONCLUSION

Multi-incident analysis is a useful tool for identifying themes that recur in similar events and presents opportunities for system-wide improvement. Common themes and contributing factors were identified which may provide possibilities for earlier identification and intervention in childhood serious bacterial infection and/or sepsis.

Development of a Trigger Tool to Identify Adverse Events and Harm in a Neuropsychiatry Setting

BACKGROUND OBJECTIVES

Adverse drug events (ADEs) present the greatest risk of harm to patients in hospitals, especially those receiving neuropsychiatric treatment. The objective of the present record-based study was to test the appropriateness of the neuropsychiatry trigger tool (NPTT) to identify and measure harm due to adverse events (AEs).

METHODS

A total of 1324 clinical case notes of discharged patients from 2017 to 2018 with a hospital stay >24 hours to <70 days were examined.

RESULTS

One hundred forty-four (10.88%) patients experienced 166 AEs. A total of 854 triggers (range, 1-12 triggers per patient) were identified in 296 (22.36%) and 39 (2.94%) patients presented with triggers at admission. The overall AE rate per 1000 patient days was 12.73 (intensive care unit, 21; inpatient department, 11.54). Triggers at admission were altered sensorium and abnormal behavior followed by headache, ataxia, and aspiration pneumonia. A small number of triggers accounted for most AEs (laxative, rising liver function test (LFT), hypokalemia, hyponatremia, health care-associated infections, intubation, abnormal behavior/sensorium, hepatic encephalopathy, antiemetics), although type of AE reported differed by level of care. Most AEs caused minor harm, and relatively fewer patients experienced temporary harm requiring intervention (110; 8.29%), permanent harm (45; 3.39%), harm requiring initial/prolonged hospitalization (10; 0.75%), interventions to sustain life (24; 1.81%), and death (109; 8%). The higher the number of AEs, the longer was the length of stay (average increased from 9.32 to 17.33 days). The NPTT identified 30 times more AEs compared with 5 AEs reported by voluntary method. Medication-related ADEs were found in 130 (90%) of 144 patients who experienced AEs. Antitubercular drugs caused most ameliorable AEs (visual disturbance, drug-induced vomiting, deranged LFT, constipation). Care is needed in attributing harm because some triggers (abnormal sensorium/behavior, intubation, headache/dizziness, laxatives) may overlap with neurological illnesses (cerebrovascular accident [CVA]/meningitis/stroke). If the triggers are identified early, harm/discomfort to the patients can be reduced. The NPTT can be used in patient safety improvement projects. Harm occurred in 296 (22.28%) patients (temporary, 120 [9%]; permanent, 178 [13%]). Adverse events prolonged hospital stay (14.29 days) compared with 9.32 days in patients without AEs.

CONCLUSIONS

A higher number of triggers per patient (≥5), trigger nature (intubation, cardiac arrest/shock), or the presenting illness (CVA/neuroinfections/status epilepticus/prolonged seizures) were correlated with the highest harm, that is, death. Because some triggers (abnormal sensorium/behavior, headache/dizziness, laxatives, intubation) may overlap with neurological illness (CVA/meningitis/stroke), care is needed in attributing harm. The NPTT identified 30 times more AEs compared with 5 AEs reported by voluntary method. Antitubercular drugs caused ameliorable AEs (visual disturbance, drug-induced vomiting, deranged LFT, constipation) and, if identified early, can reduce harm/discomfort to the patients.

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.

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.

Principles of Pediatric Patient Safety: Reducing Harm Due to Medical Care

Pediatricians render care in an increasingly complex environment, which results in multiple opportunities to cause unintended harm. National awareness of patient safety risks has grown since the National Academy of Medicine (formerly the Institute of Medicine) published its report "To Err Is Human: Building a Safer Health System" in 1999. Patients and society as a whole continue to challenge health care providers to examine their practices and implement safety solutions. The depth and breadth of harm incurred by the practice of medicine is still being defined as reports continue to reveal a variety of avoidable errors, from those that involve specific high-risk medications to those that are more generalizable, such as patient misidentification and diagnostic error. Pediatric health care providers in all practice environments benefit from having a working knowledge of patient safety language. Pediatric providers should serve as advocates for best practices and policies with the goal of attending to risks that are unique to children, identifying and supporting a culture of safety, and leading efforts to eliminate avoidable harm in any setting in which medical care is rendered to children. In this Policy Statement, we provide an update to the 2011 Policy Statement "Principles of Pediatric Patient Safety: Reducing Harm Due to Medical Care."

Patient Characteristics Associated With Voluntary Safety Event Reporting in the Acute Care Setting

OBJECTIVES

Adverse events are increasingly important to health care delivery and financial reimbursement. Most hospitals use voluntary event reporting (VER) systems to detect safety events, which may be vulnerable to individual and systemic biases. We tested the hypothesis that patient demographic factors such as weight status and race would be associated with safety event reporting in the acute care setting.

METHODS

We reviewed all acute care encounters for patients 2 to 17 years of age and corresponding safety events entered in the VER system of a tertiary-care children's hospital from February 2015 to February 2016. Data collected included patient demographics, clinical characteristics, incident description, and reported harm score. Our primary outcome was any report of a safety event. Using χ² and multivariable logistical regression methods, we determined patient characteristics associated with safety event reporting.

RESULTS

A total of 22 056 patient encounters were identified, and 341 (1.5%) of those had a reported safety event. In univariate analysis, age, weight category, and race were found to be significantly associated with event reporting, whereas sex and insurance provider were not. In the multivariable logistic regression model, obesity (odds ratio [OR] 0.69; 95% confidence interval [CI] 0.49-0.97) and African American race (OR 0.65; 95% CI 0.46-0.93) were negatively associated with event reporting, whereas length of stay was positively associated (OR 1.51; 95% CI 1.46-1.55).

CONCLUSIONS

We identified associations between patient demographic factors and voluntary safety event reporting in the acute care setting. In future studies, we will compare VER to event identification by more objective measures, such as a trigger tool.

Views of children, parents, and health-care providers on pediatric disclosure of medical errors

Despite the prevalence of medical errors in pediatrics, little research examines stakeholder perspectives on the disclosure of adverse events, particularly in the case of children's own perspectives. Stakeholder perspectives, however, are integral to informing processes for pediatric disclosure. Building on a systematic review of the literature, this article presents findings from a series of focus groups with key pediatric stakeholders where perspectives were sought on the disclosure of medical errors. Focus groups were conducted with three stakeholder groups. Participants included child members of the Children's Council from a large pediatric hospital (n = 14), parents of children with chronic medical conditions (n = 5), and health-care providers including physicians, nurses, and patient safety professionals (n = 27). Children acknowledged various disclosure approaches while citing the importance of children's right to know about errors. Parents generally identified the need for full disclosure and the uncovering of hidden errors. Health-care providers were concerned about the process of disclosure and whether it always served the best interest of the child or family. While some health-care providers addressed the need for more clarity in pediatric policies, most stakeholders agreed that a case-by-case approach was necessary for supporting variations in how medical errors are disclosed.

Less is More: Modern Neonatology

Iatrogenesis is more common in neonatal intensive care units (NICUs) because the infants are vulnerable and exposed to prolonged intensive care. Sixty percent of extremely low-birth-weight infants are exposed to iatrogenesis. The risk factors for iatrogenesis in NICUs include prematurity, mechanical or non-invasive ventilation, central lines, and prolonged length of stay. This led to the notion that "less is more." In the delivery room delayed cord clamping is recommended for term and preterm infants, and suction for the airways in newborns with meconium-stained fluid is not performed anymore. As a symbol for a less aggressive attitude we use the term neonatal stabilization rather than resuscitation. Lower levels of oxygen saturations are accepted as normal during the first 10 minutes of life, and if respiratory assistance is needed, we no longer use 100% oxygen but 0.21-0.3 FiO₂, depending on gestational age and the level of oxygen saturation. We try to avoid endotracheal ventilation by using non-invasive respiratory support and administering continuous positive airway pressure early on, starting in the delivery room. If surfactant is needed, non-invasive methods of surfactant administration are utilized. Use of central lines is shortened, and early feeding of human milk is the routine. Permissive hypercapnia is allowed, and continuous non-invasive monitoring not only of the O₂ but also of CO₂ is warranted. "Kangaroo care" and Newborn Individualized Developmental Care and Assessment Program (NIDCAP) together with a calm atmosphere with parental involvement are encouraged. Whether "less is more," or not enough, is to be seen in future studies.

Introduction of pharmacy technicians onto a busy oncology ward as part of the nursing team

A project was planned to explore the practicality of using pharmacy technicians to support the workload of nursing teams on a busy haematology oncology ward of 28 beds in a university acute care children's hospital of 300 beds. The question asked was, could pharmacy technicians be part of the nursing team to undertake what has traditionally been considered a nursing role? Three pharmacy technicians were trained and participated in the study. Assisting in the preparation and administration of 509 intravenous injections out of a possible 1123 (45%) of all intravenous injections prepared on the ward during the study period. The results indicated a reduction in adverse events of 1-2 a day during the study period, a reduction in work-related stress by nursing staff associated with preparing complex medication and releasing a nurse, 4 hours a day to enable them additional time to care for patients.

Is the "July Effect" Real? Pediatric Trainee Reported Medical Errors and Adverse Events

Introduction:

The “July Effect” suggests an increase in patient adverse events in July compared with other months due to the introduction of new providers throughout the training continuum. The aim of this initiative was to analyze reported pediatric trainee medical errors from May through September 2015 at a tertiary care free-standing academic children’s hospital to determine if there were more reported medical errors and more adverse events from those errors in July.

Methods:

An error surveillance system is used to report and track near misses, adverse events, and medical errors. Three of the authors reviewed each report, which was electronically collected in the institution during the time period of interest. The reported medical error incidence per 1,000 trainee-days was compared against those in July for a significant difference.

Results:

There are a total of 282 trainees (86 pediatric residents, 81 nonpediatric residents, and 115 fellows) who are clinically active in the hospital at any given month. Pediatric residents had more reported medical errors in July (31) compared with May (16; P = 0.015), June (16; P = 0.019), and August (19; P = 0.046). There was no significant difference in the number of adverse events from reported medical errors by trainees in July (7) compared with May (5), June (8), August (4), or September (8; P > 0.2).

Conclusion:

In this single-center evaluation, there is an increase in reported medical errors involving pediatric residents in July compared with the months surrounding July. However, there is no difference in numbers of adverse events from those errors between these months.

Assessing safety culture in NICU: psychometric properties of the Italian version of Safety Attitude Questionnaire and result implications

RATIONALE, AIMS AND OBJECTIVE

Neonatal intensive care units (NICUs) are a high-risk setting. The Safety Attitude Questionnaire (SAQ) is a widely used tool to measure safety culture. The aims of the study are to verify the psychometric properties of the Italian version of SAQ, to evaluate safety culture in the NICUs and to identify improvement interventions.

METHOD

A cross-sectional study was conducted in 6 level III NICUs. The SAQ was translated into Italian and adapted to the context, a confirmatory factor analysis (CFA) was performed to validate the questionnaire.

RESULTS

193 questionnaires were collected. The mean response rate was 59.7% (range 44.5%-95.7%). The answers were analysed according to six factors: f1 - teamwork climate, f2 - safety climate, f3 - job satisfaction, f4 - stress recognition, f5 - perception of management, f6 - working conditions. The CFA indexes were adequate (McDonald's omega indexes varied from 0.74 to 0.94, the SRMR index was equal to 0.79 and the RMSEA index was 0.070, 95% CI = 0.063-0.078). The mean composite score was 57.6 (SD 17.9), ranging between 42.3 and 69.7 on a standardized 100-point scale. We highlighted significant differences among units and professions (P < 0.05).

CONCLUSIONS

The Italian version of the SAQ proved to be an effective tool to evaluate and compare the safety culture in the NICUs. The obtained scores significantly varied both within and among the NICUs. The organizational and structural characteristics of the involved hospitals probably affect the safety culture perception by the staff.

An Indian pediatric emergency weight estimation tool: prospective adjustment of the Broselow tape

BACKGROUND

This study aims to remodel the Broselow Pediatric Emergency Tape for the Indian pediatric population. The Broselow tape overestimates the heights of the Indian pediatric population and remits inaccurate predicted weights for all color zones with varying degrees and could result in overresuscitation of Indian children in emergency settings. The Indian children are underweight for their age and height.

METHODS

We prospectively collected cross-sectional data on a sample of 1185 children aged 1 month to 12 years old in Chennai, India. The Broselow tape was used for length-based weight estimation, and actual weight was recorded by a weighing scale. In the first stage, we recruited 769 children. With univariate linear regression, we adjusted the Broselow tape by an 8 % correction factor to enhance accuracy and created a new tape with new weight and height ranges. In the second stage, we recruited 416 children and tested the new ranges for accuracy.

RESULTS

The Broselow tape overestimates weights with a mean percentage difference of 5-15 % depending on the color zone. Accuracy of the Broselow tape by color-coded zone was between 33-86.6 %, with higher weight color zones showing lower accuracy. The new Indian pediatric weight estimation tool (IPWET), based on the Broselow tape has a weight range of 4-36 kg and height range of 50-150 cm (Broselow tape, 3-36 kg, 46-146.5 cm) and an improved accuracy between 51-97.8 %.

CONCLUSIONS

A remodeled Broselow tape can predict weights with higher accuracy in the Indian pediatric population.

A trigger tool to detect harm in pediatric inpatient settings

OBJECTIVES

An efficient and reliable process for measuring harm due to medical care is needed to advance pediatric patient safety. Several pediatric studies have assessed the use of trigger tools in varying inpatient environments. Using the Institute for Healthcare Improvement's adult-focused Global Trigger Tool as a model, we developed and pilot tested a trigger tool that would identify the most common causes of harm in pediatric inpatient environments.

METHODS

After formal training, 6 academic children's hospitals used this novel pediatric trigger tool to review 100 randomly selected inpatient records per site from patients discharged during the month of February 2012.

RESULTS

From the 600 patient charts evaluated, 240 harmful events ("harms") were identified, resulting in a rate of 40 harms per 100 patients admitted and 54.9 harms per 1000 patient days across the 6 hospitals. At least 1 harm was identified in 146 patients (24.3% of patients). Of the 240 total events, 108 (45.0%) were assessed to have been potentially or definitely preventable. The most common patient harms were intravenous catheter infiltrations/burns, respiratory distress, constipation, pain, and surgical complications.

CONCLUSIONS

Consistent with earlier rates of all-cause harm in adult hospitals, harm occurs at high rates in hospitalized children. Availability and use of an all-cause harm identification tool will establish the epidemiology of harm and will provide a consistent approach to assessing the effect of interventions on harms in hospitalized children.

Development of a consensus-base list of criteria for prescribing medication in a pediatric population

BACKGROUND

Although many people are involved in the optimal use of a medication within this process, the use of medications carries risks of adverse events, which are greater in the pediatric population because of many factors.

OBJECTIVE

In this context, our aim was to develop a consensus-based list of criteria for the safety of the pediatric medication-use process or circuit (referred to from now on as the CIRCUS tool: CIRcuit-of-Child-drug-USe).

SETTING

Multicenter with a trio of experts from eight university hospitals.

METHODS

A literature search (1998-2013) was conducted in order to identify the different safety practice domains for the pediatric medication use process. Twenty-six safety practice domains were identified and 48 compliance criteria were formulated. In order to reach a consensus on the most relevant compliance criteria for safety practices, an international 24 French-speaking multidisciplinary panelists (8 doctors, 8 pharmacists and 8 nurses) selected to represent a broad range of experience levels and specialties took part in a two round Delphi survey which was conducted between March and July 2013. Each panelist was asked to rate each proposed criterion on a 1-9 Likert scale in order to show their level of agreement (i.e. 1 reflects strong disagreement and 9 reflects strong agreement).

MAIN OUTCOME MEASURE

Development of a consensus-base list for safety practices in pediatrics.

RESULTS

Twenty-two of the 24 professionals invited to take part in this survey (92% participation rate) completed the two Delphi rounds. At the end of the two Delphi rounds, a total of 38/48 (79%) safety practice compliance criteria achieved consensus by the panelists. The criteria were grouped into 23 domains.

CONCLUSION

This study presents the development of a self-assessment tool for safety practices in the pediatric drug-use process using a Delphi method. This tool may be used in order to record and compare the prevalence of best safety practices in the pediatric drug-use process.

Paediatric critical incident analysis: lessons learnt on analysis, recommendations and implementation

The objectives of this study were to identify causal and contributing factors of serious patient safety incidents in a paediatric university hospital, to report on ensuing recommendations and to assess the extent of implementation of the recommendations. The possible causal and contributing factors identified in 17 incidents were classified by a system devised by Vincent et al. Proposed recommendations were classified by the same system, and degrees of implementation were established. A median of 5 causal and contributing factors per incident were identified. Twenty-two percent of all factors were related to teamwork and 22 % to task factors. A median of 5 recommendations per analysis were formulated. Most recommendations were related to task factors (36 %). The time load of each analysis was a mean of 27 h. One third of the recommendations have been acted upon, mostly those related to task and team factors.

CONCLUSION

Incident analysis is time-consuming but yields indispensable information on causal and contributing factors, presenting numerous opportunities for quality improvement. The value of these analyses could be improved by appointing responsibilities and setting up time frames for implementation. A bottom-up approach with managerial support appears to be a key to turning incident analysis and quality improvement into an ongoing process.

Measuring pediatric hospital readmission rates to drive quality improvement

The Pediatric Quality Measures Program is developing readmission measures for pediatric use. We sought to describe the importance of readmissions in children and the challenges of developing readmission quality measures. We consider findings and perspectives from research studies and commentaries in the pediatric and adult literature, characterizing arguments for and against using readmission rates as measures of pediatric quality and discussing available evidence and current knowledge gaps. The major topic of debate regarding readmission rates as pediatric quality measures is the relative influence of hospital quality versus other factors within and outside of health systems on readmission risk. The complex causation of readmissions leads to disagreement, particularly when rates are publicly reported or tied to payment, about whether readmissions can be prevented and how to achieve fair comparisons of readmission performance. Despite these controversies, the policy focus on readmissions has motivated widespread efforts by hospitals and outpatient providers to evaluate and reengineer care processes. Many adult studies demonstrate a link between successful initiatives to improve quality and reductions in readmissions. More research is needed on methods to enhance adjustment of readmission rates and on how to prevent pediatric readmissions.

Identifying significant and relevant events during pediatric transport: a modified Delphi study

OBJECTIVES

Children must often be transported to dedicated pediatric centers to receive specialized medical and surgical care, which places them at risk for significant deterioration and life-threatening events. Studies designed to identify and mitigate these events have been limited by variability in the selection and definition of significant events. The objective of this study was to identify and evaluate indicators that represent significant events during the transport of pediatric patients and are relevant to future research initiatives in transport medicine.

DESIGN

We conducted a modified Delphi study consisting of four iterations.

SETTING

The expert panel included Canadian, interdisciplinary healthcare providers with transport experience.

INTERVENTIONS

In the first Delphi iteration, experts suggested indicators for consideration and evaluated proposed indicators from the literature and introduced by the study steering committee. In subsequent iterations, respondents reevaluated all indicators that had not yet achieved a priori-defined consensus; group comments and aggregate scores for each indicator from previous iterations were provided.

MEASUREMENTS AND MAIN RESULTS

The expert panel consisted of 16 physicians and 17 nonphysician healthcare providers from 10 Canadian institutions. In total, the panel evaluated 57 indicators, including 26 not previously presented in the literature. The expert panel determined 52 were significant and relevant to future studies in pediatric transport. The final indicator list includes trigger tools (interventions, physiological markers, and laboratory values) and team member safety and process issues.

CONCLUSIONS

Using a systematic, modified Delphi approach, we developed an inclusive list of indicators for application to pediatric transport-related quality improvement and clinical research projects.

Situation Awareness and Interruption Handling During Medication Administration

Medication administration error remains a leading cause of preventable death. A gap exists in understanding attentional dynamics, such as nurse situation awareness (SA) while managing interruptions during medication administration. The aim was to describe SA during medication administration and interruption handling strategies. A cross-sectional, descriptive design was used. Cognitive task analysis (CTA) methods informed analysis of 230 interruptions. Themes were analyzed by SA level. The nature of the stimuli noticed emerged as a Level 1 theme, in contrast to themes of uncertainty, relevance, and expectations (Level 2 themes). Projected or anticipated interventions (Level 3 themes) reflected workload balance between team and patient foregrounds. The prevalence of cognitive time-sharing during the medication administration process was remarkable. Findings substantiated the importance of the concept of SA within nursing as well as the contribution of CTA in understanding the cognitive work of nursing during medication administration.

Phenotyping for patient safety: algorithm development for electronic health record based automated adverse event and medical error detection in neonatal intensive care

Background

Although electronic health records (EHRs) have the potential to provide a foundation for quality and safety algorithms, few studies have measured their impact on automated adverse event (AE) and medical error (ME) detection within the neonatal intensive care unit (NICU) environment.

Objective

This paper presents two phenotyping AE and ME detection algorithms (ie, IV infiltrations, narcotic medication oversedation and dosing errors) and describes manual annotation of airway management and medication/fluid AEs from NICU EHRs.

Methods

From 753 NICU patient EHRs from 2011, we developed two automatic AE/ME detection algorithms, and manually annotated 11 classes of AEs in 3263 clinical notes. Performance of the automatic AE/ME detection algorithms was compared to trigger tool and voluntary incident reporting results. AEs in clinical notes were double annotated and consensus achieved under neonatologist supervision. Sensitivity, positive predictive value (PPV), and specificity are reported.

Results

Twelve severe IV infiltrates were detected. The algorithm identified one more infiltrate than the trigger tool and eight more than incident reporting. One narcotic oversedation was detected demonstrating 100% agreement with the trigger tool. Additionally, 17 narcotic medication MEs were detected, an increase of 16 cases over voluntary incident reporting.

Conclusions

Automated AE/ME detection algorithms provide higher sensitivity and PPV than currently used trigger tools or voluntary incident-reporting systems, including identification of potential dosing and frequency errors that current methods are unequipped to detect.

[Adverse events in a Neonatal Intensive Care Unit]

This was a prospective, observational study conducted in a neonatal intensive care unit to determine the incidence of adverse events. A specific trigger tool instrument was used, based on the one from Vermont-Oxford Network. A total of 218 neonates were followed and AEs were detected in 183 (84%) of them, with a rate of 2,6 AE/patient. Thermoregulation disorders (29%), disorders of glycemic control (17,1%) and nosocomial infections (13,5%) were the most frequent. Some AE were associated with birth weight (p<0.05). The accidental extubations and nosocomial infections were associated with hospital days. The incidence of AEs is high, especially among neonates with very low birth weight. Best practices regarding preventive strategies are necessary to improve quality of health care for these infants.

Is preventable harm the right patient safety metric?

Despite increasing attention and discussion, patient harm remains an important issue in health care. Defining and identifying harm remains challenging, and little standardization in approach exists. This summary describes an approach to identifying hospital-wide preventable harm with focused safety efforts using the Preventable Harm Index as a measure of progress and as a metric to motivate improvement. Our hospital's significant decrease in serious safety events, mortality, and preventable harm is outlined.

Medication errors reported in a pediatric intensive care unit for oncologic patients

BACKGROUND

Considering all sources of errors that may occur during healthcare, medication errors are the most common and also the most frequent cause of adverse events.

OBJECTIVE

The objective of the study was to describe the medication errors reported in a pediatric intensive care unit for oncologic patients.

METHODS

This is a descriptive and exploratory study. The errors were reported by the professionals involved in the medication system in a medication error report form developed for the study.

RESULTS

The sample consisted of 110 medication errors reported on 71 forms. The omission error was the most common error type reported (22.7%), followed by administration error (18.2%). No harm to patients was reported in 83.1% of the notifications.

CONCLUSION

The analysis of the110 medication errors provides evidence of the context of their occurrence and the need to implement measures that can prevent or intercept these errors.

IMPLICATIONS FOR PRACTICE

In an institution without adverse events report and a formal system to patient safety analysis, the implementation of a local nonpunitive approach to medication errors notification represented an important tool to patient safety promotion.

Erros de medicação em pediatria

A segurança do paciente constitui problema de saúde pública, e erros com medicamentos são os mais freqüentes e graves. O artigo apresenta características epidemiológicas dos erros de medicação em diferentes áreas de atendimento pediátrico, e aponta estratégias de prevenção. Aproximadamente 8% das pesquisas sobre erros de medicação identificadas em bases de dados nacionais e internacionais referem-se à população pediátrica. Crianças apresentam maior vulnerabilidade à ocorrência de erros devido a fatores intrínsecos, destacando-se características anatômicas e fisiológicas; e extrínsecos, relativos à falta de políticas de saúde e da indústria farmacêutica voltadas ao atendimento de tais especificidades. As evidências apontam para a necessidade de implementação de estratégias de prevenção de erros de medicação, contribuindo para promover a segurança do paciente.

Policy statement--principles of pediatric patient safety: reducing harm due to medical care

Pediatricians are rendering care in an environment that is increasingly complex, which results in multiple opportunities to cause unintended harm. National awareness of patient safety risks has grown in the 10 years since the Institute of Medicine published its report To Err Is Human, and patients and society as a whole continue to challenge health care providers to examine their practices and implement safety solutions. The depth and breadth of harm incurred by the practice of medicine is still being defined as reports continue to uncover a variety of avoidable errors, from those that involve specific high-risk medications to those that are more generalizable, such as patient misidentification. Pediatricians in all venues must have a working knowledge of patient-safety language, advocate for best practices that attend to risks that are unique to children, identify and support a culture of safety, and lead efforts to eliminate avoidable harm in any setting in which medical care is rendered to children.

A new framework for quality partnerships in Children's Hospitals

Children's hospitals and their affiliated departments of pediatrics often pursue separate programs in quality and safety; by integrating these programs, they can accelerate progress. Hospital executives and pediatric department chairs from 14 children's hospitals have been exploring practical approaches for integrating quality programs. Three components provide focus: (1) alignment of quality priorities and resources across the organizations; (2) education and training for physicians in the science of improvement; and (3) professional development and career progression for physicians in recognition of quality-improvement activities. Process and resource requirements are identified for each component, and specific, actionable steps are identified. The action steps are arrayed on a continuum from basic to advanced integration. The resulting matrix serves as an "integration framework," useful to a hospital and its pediatric academic department at any stage of integration for assessing its current state, plotting a path toward further integration, tracking its progress, and identifying potential collaborators and models of advanced integration. The framework contributes to health care's quality-improvement movement in multiple ways: it addresses a basic impediment to quality and safety improvement; it is an implementable model for integrating quality programs; it offers career-advancement potential for physicians interested in quality; it helps optimize investments in quality and safety; and it can be applied both within a single children's hospital and across multiple children's hospitals. Widespread adoption of the integration framework could have a transformative effect on the children's hospital sector, not the least of which is improved quality and safety on a large scale.

Performance characteristics of a methodology to quantify adverse events over time in hospitalized patients

OBJECTIVE

To assess the performance characteristics of the Institute for Healthcare Improvement Global Trigger Tool (GTT) to determine its reliability for tracking local and national adverse event rates.

DATA SOURCES

Primary data from 2008 chart reviews.

STUDY DESIGN

A retrospective study in a stratified random sample of 10 North Carolina hospitals. Hospital-based (internal) and contract research organization-hired (external) reviewers used the GTT to identify adverse events in the same 10 randomly selected medical records per hospital in each quarter from January 2002 through December 2007.

DATA COLLECTION/EXTRACTION

Interrater and intrarater reliability was assessed using κ statistics on 10 percent and 5 percent, respectively, of selected medical records. Additionally, experienced GTT users reviewed 10 percent of records to calculate internal and external teams' sensitivity and specificity.

PRINCIPAL FINDINGS

Eighty-eight to 98 percent of the targeted 2,400 medical records were reviewed. The reliability of the GTT to detect the presence, number, and severity of adverse events varied from κ=0.40 to 0.60. When compared with a team of experienced reviewers, the internal teams' sensitivity (49 percent) and specificity (94 percent) exceeded the external teams' (34 and 93 percent), as did their performance on all other metrics.

CONCLUSIONS

The high specificity, moderate sensitivity, and favorable interrater and intrarater reliability of the GTT make it appropriate for tracking local and national adverse event rates. The strong performance of hospital-based reviewers supports their use in future studies.

Neonatal Informatics: Computerized Physician Order Entry

Computerized physician order entry (CPOE) is the feature of electronic medical record (EMR) implementation that arguably offers the greatest quality and patient safety benefits. The gains are potentially greater for critically ill neonates, but the effect of CPOE on quality and safety is dependent upon local implementation decisions. OBJECTIVES: After completing this article, readers should be able to: Define the basic aspects of CPOE and clinical decision support (CDS) systems.Describe the potential benefits of implementing CPOE associated with CDS in a neonatal intensive care unit (NICU).

Prevalence of adverse events in pediatric intensive care units in the United States

OBJECTIVES

Selection of relevant patient safety interventions for the pediatric intensive care (PICU) requires identification of the types and severity of adverse events (AEs) and adverse drug events (ADEs) that occur in this setting. The study's objectives were to: 1) determine the rates of AEs/ADEs, including types, severity, and preventability, in PICU patients; 2) identify population characteristics associated with increased risk of AEs/ADEs; 3) develop and test a PICU specific trigger tool to facilitate identification of AEs/ADEs.

DESIGN, SETTING, PATIENTS

Retrospective, cross-sectional, randomized review of 734 patient records who were discharged from 15 U.S. PICUs between September and December 2005.

INTERVENTION

A novel PICU-focused trigger tool for AE/ADE detection.

MEASUREMENTS AND RESULTS

Sixty-two percent of PICU patients had at least one AE. A total of 1488 AEs, including 256 ADEs, were identified. This translates to a rate of 28.6 AEs and 4.9 ADEs per 100 patient-days. The most common types of AEs were catheter complications, uncontrolled pain, and endotracheal tube malposition. Ten percent of AEs were classified as life-threatening or permanent; 45% were deemed preventable. Higher adjusted rates of AEs were found in surgical patients (p = .02), patients intubated at some point during their PICU stay (p = .002), and patients who died (p < .001). Surgical patients had higher preventable adjusted AE (p = .01) and ADE rates (p = .02). The adjusted cumulative risk of an AE per PICU day was 5.3% and 1.6% for an ADE alone. There was a 4% increase in adjusted ADEs rates for every year increase in age.

CONCLUSIONS

AEs and ADEs occur frequently in the PICU setting. These data provide areas of focus for evidence-based prevention strategies to decrease the substantial risk to this vulnerable pediatric population.

Measuring hospital adverse events: assessing inter-rater reliability and trigger performance of the Global Trigger Tool

OBJECTIVE

To determine the inter-rater reliability of the Institute for Healthcare Improvement's Global Trigger Tool (GTT) in a practice setting, and explore the value of individual triggers.

DESIGN

Prospective assessment of application of the GTT to monthly random samples of hospitalized patients at four hospitals across three regions in the USA.

SETTING

Mayo Clinic campuses are in Minnesota, Arizona and Florida.

PARTICIPANTS

A total of 1138 non-pediatric inpatients from all units across the hospital.

INTERVENTION

GTT was applied to randomly selected medical records with independent assessments of two registered nurses with a physician review for confirmation.

MAIN OUTCOME MEASURE

The Cohen Kappa coefficient was used as a measure of inter-rater agreement. The positive predictive value was assessed for individual triggers.

RESULTS

Good levels of reliability were obtained between independent nurse reviewers at the case-level for both the occurrence of any trigger and the identification of an adverse event. Nurse reviewer agreement for individual triggers was much more varied. Higher agreement appears to occur among triggers that are objective and consistently recorded in selected portions of the medical record. Individual triggers also varied on their yield to detect adverse events. Cases with adverse events had significantly more triggers identified (mean 4.7) than cases with no adverse events (mean 1.8).

CONCLUSIONS

The trigger methodology appears to be a promising approach to the measurement of patient safety. However, automated processes could make the process more efficient in identifying adverse events and has a greater potential of improving care delivery and patient 'outcomes'.

Pharmacotherapy in pediatric critical illness: a prospective observational study

BACKGROUND AND OBJECTIVES

Pharmacotherapy is an under-evaluated element of critical care medicine. In order to better understand pharmacotherapy in pediatric critical illness, we evaluated a cohort of emergency admissions to a university-affiliated pediatric intensive care unit (PICU).

METHODS

A prospective, observational study was performed. Eligible patients were admitted to this medical-surgical ICU for at least 24 hours. The primary outcomes were the number of drug orders written, the number of different medications ordered, and the number of drug administrations. Multiple regression analyses were used to identify factors independently associated with each primary outcome.

RESULTS

We studied 100 patients with a median age of 40 months (interquartile range [IQR] 9-82), who were admitted for a total of 851 ICU days. These patients received 4419 drug orders and 11 911 intermittent dose-administrations of 241 different medications. Each patient received a median of 29.5 (IQR 16.5-48.5) drug orders, 14 (IQR 9-18.5) different medications, and 58 (IQR 28-129) drug administrations while in the ICU. The most frequent orders were for morphine 457 (10.6%), furosemide (frusemide) 337 (7.8%), potassium 237 (5.5%), lorazepam 226 (5.2%), and albuterol (salbutamol) 158 (3.7%). The duration of PICU stay and severity of illness were independently associated with all primary outcomes.

CONCLUSIONS

Pharmacotherapy is an active component in the practice of pediatric critical care medicine. We demonstrated that increasing numbers of ordered medications, drug orders, and drug administrations were associated with increasing duration of ICU therapies and the length of ICU stay. These data underscore the potential importance of improved safety and efficacy of medicines used to treat critically ill children.

Implementing a pediatric rapid response system to improve quality and patient safety

Life-threatening events are common in today's hospitals, where an increasing proportion of patients with urgent admission are cared for by understaffed, often inexperienced personnel. Medical errors play a key role in causing adverse events and failure to rescue deteriorating patients. In-hospital cardiac arrest outcomes are generally poor, but these events are often preceded by a pattern of deterioration with abnormal vital signs and mental status. When hospital staff or family members observe warning signs and trigger timely intervention by a rapid response team, rates of cardiac arrest and mortality can be reduced. Rapid response team involvement can be used to trigger careful review of preceding events to help uncover important systems issues and allow for further improvements in patient safety.

Impact of a computerized physician order-entry system

BACKGROUND

The Institute of Medicine has urged the adoption of electronic prescribing systems in all health-care organizations by 2010. Accordingly, computerized physician order entry (CPOE) warrants detailed evaluation. Mixed results have been reported about the benefit of this system. No review of its application in surgical patients has been reported to date. We present the implementation of CPOE in the management of surgical patients within an academic multispecialty practice.

STUDY DESIGN

Retrospective and prospective analyses of patient-safety measures were done pre- and post-CPOE institution, respectively. Other metrics evaluated included medication errors, order-implementation times, efficiencies, personnel requirements, and physician time. Sampling of time span for the order placement process was assessed with direct hidden observation of the provider.

RESULTS

A total of 15 (0.22%) medication errors were discovered in 6,815 surgical procedures performed during the 6 months before CPOE use. After implementation, 10 medication errors were found (5,963 surgical procedures [0.16%]) in the initial 6 months and 13 (0.21%) in the second 6 months (6,106 surgical procedures) (p = NS). Mean total time from placement of order to nurse receipt before implementation was 41.2 minutes per order (2.05 minutes finding chart, 0.72 minutes writing order, 38.4 minutes for unit secretary transcription) compared with 27 seconds per order using CPOE (p < 0.01). Four additional informational technology specialists were temporarily required for assistance in implementing CPOE. After CPOE adoption, 11 of 56 (19.6%) ancillary personnel positions were eliminated related to order-entry efficiencies.

CONCLUSIONS

Present CPOE technology can allow major efficiency gains, but refinements will be required for improvements in patient safety.

[Field 8. Safety practices in paediatric intensive care medicine. French-speaking Society of Intensive Care. French Society of Anesthesia and Resuscitation]

A paediatric intensive care unit is a complex environment with many hazards for potential medical errors. Due to the high acuity of illness and the complexity of medical care with multiple disciplines and individuals involved, medical errors occur due to breakdowns in communication and teamwork. Medication errors are the most frequent errors in paediatrics. This chapter proposes some strategies to prevent medical errors in paediatric intensive care units.

Iatrogenesis in neonatal intensive care units: observational and interventional, prospective, multicenter study

OBJECTIVES

The goals were to determine the incidence of iatrogenic events in NICUs and to determine whether awareness of iatrogenic events could influence their occurrence.

METHODS

We performed a prospective, observational, interventional, multicenter study including all consecutive infants hospitalized in 4 NICUs. In the first 3 months (observation period), the medical teams were unaware of the study; in the next 3 months (intervention period), they were made aware of daily ongoing monitoring of iatrogenic events by a designated "Iatrogenesis Advocate."

RESULTS

The numbers of infants admitted to the NICUs were comparable during the observation and intervention periods (328 and 369 infants, respectively). There was no difference between the 2 periods with respect to the number of infants of <1500 g, hospitalization days, or mean daily occupancy of the NICUs. Although the prevalence rates of iatrogenic events were comparable in the observation and intervention periods (18.0 and 18.2 infants with iatrogenic events per 100 hospitalized infants, respectively), the incidence rate decreased significantly during the intervention period (3.2 and 2.4 iatrogenic events per 100 hospitalization days of new admissions, respectively). Of all iatrogenic events, 7.9% were classified as life-threatening and 45.1% as harmful. There was no death related to an iatrogenic event. Eighty-three percent of iatrogenic events were considered preventable, of which 26.9% resulted from medical errors in ordering or delivery of medical care. Only 1.6% of all iatrogenic events were intercepted before reaching the infants, and only 47.0% of iatrogenic events were corrected. For younger and smaller infants, the rate of iatrogenic events was higher (57% at gestational ages of 24 to 27 weeks, compared with 3% at term) and the iatrogenic events were more severe and harmful. Increased length of stay was associated independently with more iatrogenic events.

CONCLUSIONS

Neonatal medical teams and parents should be aware of the burden of iatrogenesis, which occurs at a significant rate.

Reevaluating the safety profile of pediatrics: a comparison of computerized adverse drug event surveillance and voluntary reporting in the pediatric environment

OBJECTIVES

Children are at exceptionally high risk for adverse drug events. At Duke University Hospital, computerized adverse drug event surveillance and voluntary safety reporting systems work synergistically to identify adverse drug events. Here we identify the most deleterious drug classes to pediatric inpatients and determine which detection methodology provides the greatest opportunity to reduce harm.

PATIENTS AND METHODS

We evaluated all of the medication-related events detected by our computerized surveillance and safety reporting systems over a 1-year period for Duke University Hospital pediatric inpatients. Events from both systems were scored for severity and assigned a drug event category. Surveillance events were additionally scored for causality.

RESULTS

A total of 849 medication-related reports were entered into the safety reporting system, and 93 caused patient harm, resulting in an adverse drug event rate of 1.8 events per 1000 pediatric patient-days. Seventy eight of the 1537 medication-related events detected by surveillance resulted in patient harm, giving a rate of 1.6 events per 1000 patient-days. The most common events identified by the safety reporting system were failures in the medication use process (26.9%), drug omissions (16.1%), and dose- or rate-related events (12.9%). The most frequent adverse drug event surveillance categories were nephrotoxins (20.7%), narcotics and benzodiazepines (19.3%), and hypoglycemia (11.5%). Most voluntarily reported events originated in ICUs (72.0%), whereas surveillance events were split evenly across intensive and general care. There was little overlap between methodologies.

CONCLUSIONS

The epidemiology of pediatric adverse drug events is best addressed by using voluntary reporting in tandem with other strategies, such as computerized surveillance and targeted chart review. Although voluntary reporting excels at identifying administration errors, surveillance excels at detecting adverse drug events caused by high-risk medications and identifies evolving conditions that may provoke imminent patient harm. Surveillance underperformed in pediatrics when compared with adult detection rates, suggesting that tailored rules may be necessary for a robust pediatric adverse drug event surveillance system.

Improving safety for children with cardiac disease

The complexity of the modern systems providing health care presents a unique challenge in delivering care of the required quality in a safe environment. Issues of safety have been thrust into the limelight because of adverse events highly publicized in the general media. In the United States of America, improving the safety and quality in health care has been set forth as a priority for improvements in the 21st century in the report from the Institute of Medicine. Many measures have now been initiated for improving the safety of patients at hospital, regional, and national level, and through initiatives sponsored by governments and private organizations. In this review, we summarize known concepts and current issues on the safety of patients, and their applicability to children with congenital cardiac disease. Prior to examining the issues of medical error and safety, it is important to define the terminology. An error is defined as the failure of a planned action to be completed as intended, also known as an execution error, or the use of a wrong plan to achieve an aim, this representing a planning error. An active error is an error that occurs at the level of the frontline operator, and the effects of which are felt immediately. A latent error is an error in the design, organization, training and maintenance, that leads to operator errors, and the effects of which are typically dormant in the system for lengthy periods of time. Latent errors may cause harm given the right circumstances and environment. An adverse event is defined as an injury resulting from medical intervention. A preventable adverse event is an adverse event that occurs due to medical error. Negligent adverse events are a subset of preventable adverse events where the care provided did not meet the standard of care expected of that practitioner. The study of improving the delivery of safe care for our patients is a rapidly growing field. Important components for development of programmes to improve the safety of patients include the leadership for the programme, the implementation of process design based on human limitations, the promotion of teamwork and function, the anticipation of unexpected events, and the creation of a learning environment. Much is yet to be learned about the risk and incidence of adverse events during hospitalization of children with congenital cardiac disease. Errors due to human factors, such as poor communication, poor coordination, and suboptimal team work, have shown to be important causes of adverse outcomes in children undergoing cardiac surgery, and should be a focus for improvement. Future research on evaluating causes and prevention of medical errors and adverse events in this population at high risk, and consuming high resources, is essential. Issues of inadequate safeguards for patients have been prominent in the media, and have been highlighted in reports from the Institute of Medicine. Our review discusses research on the causes of medical error, and proposes concepts to design successful programmes to improve safety for the patients on a local level.
