Standard Drug Concentrations and Smart-Pump Technology Reduce Continuous-Medication-Infusion Errors in Pediatric Patients

Objective. To determine if combining standard drug concentrations with “smart-pump” technology reduces reported medication-infusion errors. Design. Preintervention and postintervention comparison of reported medication errors related to infusion therapies during the calendar years 2002 and 2003. Setting. A 242-bed university-affiliated tertiary pediatric hospital. Intervention. Change in continuous-medication-infusion process, comprising the adoption of (1) standard drug concentrations, (2) “smart” syringe pumps, and (3) human-engineered medication labels. Main Outcome Measures. Comparison of reported continuous-medication-infusion errors before and after the intervention. Results. The number of reported errors dropped by 73% for an absolute risk reduction of 3.1 to 0.8 per 1000 doses. Preparation errors that occurred in the pharmacy decreased from 0.66 to 0.16 per 1000 doses; the number of 10-fold errors in dosage decreased from 0.41 to 0.08 per 1000 doses. Conclusions. The use of standard drug concentrations, smart syringe pumps, and user-friendly labels reduces reported errors associated with continuous medication infusions. Standard drug concentrations can be chosen to allow most neonates to receive needed medications without concerns related to excess fluid administration.

An Emergency Department Septic Shock Protocol and Care Guideline for Children Initiated at Triage

BACKGROUND: Unrecognized and undertreated septic shock increases morbidity and mortality. Septic shock in children is defined as sepsis and cardiovascular organ dysfunction, not necessarily with hypotension. OBJECTIVE: Cases of unrecognized and undertreated septic shock in our emergency department (ED) were reviewed with a focus on (1) increased recognition at triage and (2) more aggressive treatment once recognized. We hypothesized that septic shock protocol and care guideline would expedite identification of septic shock, increase compliance with recommended therapy, and improve outcomes. METHODS: We developed an ED septic shock protocol and care guideline to improve recognition beginning at triage and evaluated all eligible ED patients from January 2005 to December 2009. RESULTS: We identified 345 pediatric ED patients (49% male, median age: 5.6 years), and 297 (86.1%) met septic shock criteria at triage. One hundred ninety-six (56.8%) had ≥1 chronic complex condition. Hypotension was present in 34% (n = 120); the most common findings were tachycardia (n = 251 [73%]) and skin-color changes (n = 269 [78%]). The median hospital length of stay declined over the study period (median: 181–140 hours; P < .05); there was no change in mortality rate, which averaged 6.3% (22 of 345). The greatest gains in care included more complete recording of triage vital signs, timely fluid resuscitation and antibiotic administration, and serum lactate determination. CONCLUSIONS: Implementation of an ED septic shock protocol and care guideline improved compliance in delivery of rapid, aggressive fluid resuscitation and early antibiotic and oxygen administration and was associated with decreased length of stay.

Pediatric and neonatal extracorporeal membrane oxygenation: does center volume impact mortality?*.

Objective:Extracorporeal membrane oxygenation, an accepted rescue therapy for refractory cardiopulmonary failure, requires a complex multidisciplinary approach and advanced technology. Little is known about the relationship between a center’s case volume and patient mortality. The purpose of this study was to analyze the relationship between hospital extracorporeal membrane oxygenation annual volume and in-hospital mortality and assess if a minimum hospital volume could be recommended. Design:Retrospective cohort study. Setting:A retrospective cohort admitted to children’s hospitals in the Pediatric Health Information System database from 2004 to 2011 supported with extracorporeal membrane oxygenation was identified. Indications were assigned based on patient age (neonatal vs pediatric), diagnosis, and procedure codes. Average hospital annual volume was defined as 0–19, 20–49, or greater than or equal to 50 cases per year. Maximum likelihood estimates were used to assess minimum annual case volume. Patients:A total of 7,322 pediatric patients aged 0–18 were supported with extracorporeal membrane oxygenation and had an indication assigned. Interventions:None. Measurements and Main Results:Average hospital extracorporeal membrane oxygenation volume ranged from 1 to 58 cases per year. Overall mortality was 43% but differed significantly by indication. After adjustment for case-mix, complexity of cardiac surgery, and year of treatment, patients treated at medium-volume centers (odds ratio, 0.86; 95% CI, 0.75–0.98) and high-volume centers (odds ratio, 0.75; 95% CI, 0.63–0.89) had significantly lower odds of death compared with those treated at low-volume centers. The minimum annual case load most significantly associated with lower mortality was 22 (95% CI, 22–28). Conclusions:Pediatric centers with low extracorporeal membrane oxygenation average annual case volume had significantly higher mortality and a minimum volume of 22 cases per year was associated with improved mortality. We suggest that this threshold should be evaluated by additional study.

Preventable harm occurring to critically ill children.

Objective: To develop a trigger tool for identifying adverse events occurring in critically ill pediatric patients; to identify and characterize adverse events and preventable adverse events experienced by critically ill pediatric patients; and to characterize the patients who experience preventable adverse events. Design: Retrospective chart review using a trigger tool. Setting: Pediatric intensive care unit of a tertiary, university-affiliated pediatric hospital. Patients: A systematic sample of 259 pediatric intensive care unit patients from a 1-yr period. Interventions: None. Measurements and Main Results: We measured frequency of occurrence (0.19 preventable adverse events per patient-day), severity of harm (78% minor, 19% moderate, 3% serious, no deaths), and type of event (sedation, 22%; skin, 16%; medical device complication, 14%; pulmonary, 13%; and cardiovascular, 11%). Patients who experienced preventable adverse events were younger, had longer lengths of stay, and had higher illness burdens. Preventable adverse events occurred more frequently among surgical patients than medical patients. Conclusions: Preventable adverse events occurred fairly frequently in the pediatric intensive care unit, but serious harm was rare. Conditions that increased the likelihood of a preventable adverse event were a) need for sedation or pain control; b) relative immobility; and c) need for vascular devices, feeding tubes, or ventilators. Adverse event prevention strategies that focus on improving patient monitoring under increased-risk conditions and improving early detection and treatment of potential harm will likely be more effective than strategies aimed at general error prevention.

Classifying undetermined poisoning deaths

Objective: To classify poisoning deaths of undetermined intent as either suicide or unintentional and to estimate the extent of underreported poisoning suicides. Methods: Based on 2002 statewide death certificate and medical examiner data in Utah, the authors randomly selected one half of undetermined and unintentional poisoning deaths for data abstraction and included all suicides. Bivariate analyses assessed differences in demographics, death characteristics, forensic toxicology results, mental health history, and other potentially contributing factors. Classification and regression tree (CART) analysis used information from unintentional and suicide poisoning deaths to create a classification tree that was applied to undetermined poisoning deaths. Results: The authors analyzed 41 unintentional, 87 suicide, and 84 undetermined poisonings. Undetermined and unintentional decedents were similar in the presence of opiates, physical health problems, and drug abuse. Although none of the undetermined decedents left a suicide note, previous attempt or intent to commit suicide was reported for 11 (13%) of these cases. CART analysis identified suicidal behavior, drug abuse, physical health problems, depressed mood, and age as discriminating between suicide and unintentional poisoning. It is estimated that suicide rates related to poisoning are underreported by approximately 30% and overall suicide rates by 10%. Unintentional poisoning death rates were underreported by 61%. Conclusions: This study suggests that manner of death determination relies on circumstance dependent variables that may not be consistently captured by medical examiners. Underreporting of suicide rates has important implications in policy development, research funding, and evaluation of prevention programs.

The safety culture in a children's hospital.

Efforts to improve patient safety require an understanding of organizational culture. In a survey of inpatient healthcare providers in a childrens hospital, physician perceptions of teamwork were higher than those of all other staff (P < .001). Recognition of the impact of stress and fatigue was low, and job satisfaction was high for all groups. A majority of respondents did not feel rewarded for incident reporting. Information on hospital-level safety culture can lead to targeted system improvement.

Effect of an anonymous reporting system on near-miss and harmful medical error reporting in a pediatric intensive care unit.

Adverse event reporting is a key element for improving patient safety. This study describes a new voluntary, anonymous reporting system that facilitates reporting of near-miss and patient harm events and an assessment of patient harm by the bedside care provider in a pediatric intensive care unit. The results demonstrated the effectiveness of the Patient Safety Report as a method to capture near-miss and patient harm events.

Comparative effectiveness of pleural drainage procedures for the treatment of complicated pneumonia in childhood.

OBJECTIVE To determine the comparative effectiveness of common pleural drainage procedures for treatment of pneumonia complicated by parapneumonic effusion (ie, complicated pneumonia). DESIGN Multicenter retrospective cohort study. SETTING Forty childrens hospitals contributing data to the Pediatric Health Information System. PARTICIPANTS Children with complicated pneumonia requiring pleural drainage. MAIN EXPOSURES Initial drainage procedures were categorized as chest tube without fibrinolysis, chest tube with fibrinolysis, video-assisted thoracoscopic surgery (VATS), and thoracotomy. MAIN OUTCOME MEASURES Length of stay (LOS), additional drainage procedures, readmission within 14 days of discharge, and hospital costs. RESULTS Initial procedures among 3500 patients included chest tube without fibrinolysis (n = 1762), chest tube with fibrinolysis (n = 623), VATS (n = 408), and thoracotomy (n = 797). Median age was 4.1 years. Overall, 716 (20.5%) patients received an additional drainage procedure (range, 6.8-44.8% across individual hospitals). The median LOS was 10 days (range, 7-14 days across individual hospitals). The median readmission rate was 3.8% (range, 0.8%-33.3%). In multivariable analysis, differences in LOS by initial procedure type were not significant. Patients undergoing initial chest tube placement with or without fibrinolysis were more likely to require additional drainage procedures. However, initial chest tube without fibrinolysis was the least costly strategy. CONCLUSION There is variability in the treatment and outcomes of children with complicated pneumonia. Outcomes were similar in patients undergoing initial chest tube placement with or without fibrinolysis. Those undergoing VATS received fewer additional drainage procedures but had no differences in LOS compared with other strategies.

Ventilator-Associated Events in Neonates and Children--A New Paradigm.

Objectives:To identify a pediatric ventilator-associated condition definition for use in neonates and children by exploring whether potential ventilator-associated condition definitions identify patients with worse outcomes. Design:Retrospective cohort study and a matched cohort analysis. Setting:Pediatric, cardiac, and neonatal ICUs in five U.S. hospitals. Patients:Children 18 years old or younger ventilated for at least 1 day. Interventions:None. Measurements and Main Results:We evaluated the evidence of worsening oxygenation via a range of thresholds for increases in daily minimum fraction of inspired oxygen (by 0.20, 0.25, and 0.30) and daily minimum mean airway pressure (by 4, 5, 6, and 7 cm H2O). We required worsening oxygenation be sustained for at least 2 days after at least 2 days of stability. We matched patients with a ventilator-associated condition to those without and used Cox proportional hazard models with frailties to examine associations with hospital mortality, hospital and ICU length of stay, and duration of ventilation. The cohort included 8,862 children with 10,209 hospitalizations and 77,751 ventilator days. For the fraction of inspired oxygen 0.25/mean airway pressure 4 definition (i.e., increase in minimum daily fraction of inspired oxygen by 0.25 or mean airway pressure by 4), rates ranged from 2.9 to 3.2 per 1,000 ventilator days depending on ICU type; the fraction of inspired oxygen 0.30/mean airway pressure 7 definition yielded ventilator-associated condition rates of 1.1–1.3 per 1,000 ventilator days. All definitions were significantly associated with greater risk of hospital death, with hazard ratios ranging from 1.6 (95% CI, 0.7–3.4) to 6.8 (2.9–16.0), depending on thresholds and ICU type. Each definition was associated with prolonged hospitalization, time in ICU, and duration of ventilation, among survivors. The advisory board of the study proposed using the fraction of inspired oxygen 0.25/mean airway pressure 4 thresholds to identify pediatric ventilator-associated conditions in ICUs. Conclusions:Pediatric patients with ventilator-associated conditions are at substantially higher risk for mortality and morbidity across ICUs, regardless of thresholds used. Next steps include identification of risk factors, etiologies, and preventative measures for pediatric ventilator-associated conditions.

Treatment of Pediatric Septic Shock With the Surviving Sepsis Campaign Guidelines and Picu Patient Outcomes

Objectives: The Surviving Sepsis Campaign recommends rapid recognition and treatment of severe sepsis and septic shock. Few reports have evaluated the impact of these recommendations in pediatrics. We sought to determine if outcomes in patients who received initial care compliant with the Surviving Sepsis Campaign time goals differed from those treated more slowly. Design: Single center retrospective cohort study. Setting: Emergency department and PICU at an academic children’s hospital. Patients: Three hundred twenty-one patients treated for septic shock in the emergency department and admitted directly to the PICU. Interventions: None. Measurements and Main Results: The exposure was receipt of emergency department care compliant with the Surviving Sepsis Campaign recommendations (delivery of IV fluids, IV antibiotics, and vasoactive infusions within 1 hr of shock recognition). The primary outcome was development of new or progressive multiple organ dysfunction syndrome. Secondary outcomes included mortality, need for mechanical ventilation or vasoactive medications, and hospital and PICU length of stay. Of the 321 children studied, 117 received Surviving Sepsis Campaign compliant care in the emergency department and 204 did not. New or progressive multiple organ dysfunction syndrome developed in nine of the patients (7.7%) who received Surviving Sepsis Campaign compliant care and 25 (12.3%) who did not (p = 0.26). There were 17 deaths; overall mortality rate was 5%. There were no significant differences between groups in any of the secondary outcomes. Although only 36% of patients met the Surviving Sepsis Campaign guideline recommendation of bundled care within 1 hour of shock recognition, 75% of patients received the recommended interventions in less than 3 hours. Conclusions: Treatment for pediatric septic shock in compliance with the Surviving Sepsis Campaign recommendations was not associated with better outcomes compared with children whose initial therapies in the emergency department were administered more slowly. However, all patients were treated rapidly and we report low morbidity and mortality. This underscores the importance of rapid recognition and treatment of septic shock.
