A Quality Improvement Initiative to Reduce Unnecessary Rapid Responses Using Early Warning Scores.

OBJECTIVES: The Pediatric Early Warning Score (PEWS) is an evidence-based tool that allows early collaborative assessment and intervention for a rapid response team (RRT) activation. The goal of our quality improvement initiative was to reduce the percentage of unnecessary RRT activations by 50% over 2 years without increasing PICU transfers or compromising patient safety and timely evaluation. METHODS: A PEWS system replaced preexisting vital signs-based pediatric RRT criteria and was modified through plan-do-study-act cycles. Unnecessary RRT activations, total RRT activation rate, transfers to the PICU, total clinical interventions performed per RRT, and missed RRT activation rate were compared between intervention periods. Likert scale surveys were administered to measure satisfaction with each modification. RESULTS: There was a significant decrease in the percentage of unnecessary RRT activations from 33% to 3.5% after the implementation of the PEWS and modified-PEWS systems (P < .05). The RRT activation rate decreased from 22.6 to 13.3 RRT activations per 1000 patient care days after implementation of the PEWS and modified-PEWS systems (P < .05), without changes in PICU transfer rates. Physicians reported that the PEWS system improved nursing communication and accuracy of RRT criteria (P < .05). Nursing reported that the PEWS system improved patient management and clinical autonomy (P < .05). CONCLUSIONS: The PEWS systems have been an effective means of identifying deteriorating pediatric patients and reducing unnecessary RRT activations. The new system fosters collaboration and communication at the bedside to prevent acute deterioration, perform timely interventions, and ultimately improve patient safety and outcomes.

Development of Pulmonary Hypertension During Treatment with Diazoxide: A Case Series and Literature Review.

Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycemia in infancy. The mainstay of medical management for CHI is diazoxide. Diazoxide inhibits insulin release from the pancreas, but also causes smooth muscle relaxation and fluid retention so it is typically given with chlorothiazide. In July 2015, the FDA issued a drug safety communication warning that pulmonary hypertension (PH) had been reported in 11 infants being treated with diazoxide and that the PH resolved with withdrawal of diazoxide. All three of the cases in our hospital were admitted to the neonatal intensive care unit (NICU) for hypoglycemia. All patients received thorough radiologic and laboratory evaluations related to their diagnosis of CHI. All initially improved when diazoxide was initiated. Case 1 and case 3 were discharged from the NICU on diazoxide and chlorothiazide. Case 2 developed pulmonary hypertension while still in the NICU days after an increase in diazoxide dosing. Case 1 presented to the emergency room in respiratory distress shortly after discharge from the NICU with evidence of PH and heart failure. Case 3 presented to the emergency room after 2 weeks at home due to a home blood glucose reading that was low and developed PH and heart failure while an inpatient. Discontinuation of diazoxide led to resolution of all three patients' PH within approximately one week. The experience of our hospital indicates that pulmonary hypertension may be more common than previously thought in infants taking diazoxide. It is unclear if these symptoms develop slowly over time or if there is some other, as yet undescribed, trigger for the pulmonary hypertension. Our hospital's experience adds to the body of evidence and suggests these infants may benefit from more surveillance with echocardiography.

Ten years of military pediatric care in Afghanistan and Iraq.

BACKGROUND: Besides care for injured US military personnel, doctrine also requires life-, limb-, and eyesight-saving care to all injured casualties, including children. This study's objective was to evaluate the burden and epidemiology of pediatric medical care during the past decade of military operations in Iraq and Afghanistan. METHODS: Retrospective review of two military registries of all patients admitted to combat support hospitals and forward surgical teams from 2001 through 2011 was conducted. Pediatric (PED) patients were defined as younger than 18 years. Adult patients were divided into local civilian/noncoalition military (LOCAL) and coalition (COALITION) soldiers. RESULTS: A total of 7,505 PED patients, 25,459 LOCAL adults, and 95,618 COALITION soldiers were analyzed in the primary registry. Children represented 5.8% of all admissions (11% bed days), LOCAL adults represented 20% (36% bed days), and COALITION soldiers represented 74% (53% bed days). PED median (interquartile range) length of stay was 3 days (1-7 days), longer than LOCAL with 2 days (1-6 days), and COALITION with 1 day (1-2 days) (p < 0.001). PED Injury Severity Score (ISS) was 9 (4-16), similar to LOCAL with 9 (4-16) but higher than COALITION with 5 (2-10) (p < 0.001). Mortality in trauma patients was highest in PED (8.5%) compared with LOCAL (7.1%) and COALITION (3%) (p < 0.01). Mechanisms of injury for PED trauma were blast (37%), penetrating (27%), blunt (23%), and burn (13%). Factors independently associated with PED mortality included ISS (odds ratio, 95% confidence interval) (1.08, 1.06-1.09), Glasgow Coma Scale (GCS) score (0.85, 0.82-0.88), base excess (0.87, 0.85-0.90), female sex (1.73, 1.18-2.52), age less than 8 years (1.43, 1.00-2.04), and burns (3.17, 1.89-5.32). CONCLUSION: Deployed medical facilities not staffed or equipped to typical civilian standards have a high burden of pediatric casualties requiring care. The cause of increased mortality in pediatric versus adult populations despite similar severity of injury is potentially multifactorial. Military medical planners need to consider pediatric resources and training to improve outcomes for children injured during combat. LEVEL OF EVIDENCE: Epidemiologic study, level III.
