Practice variation after implementation of a protocol for migraines in children:

Implementation strategies in emergency management of children: A scoping review

BACKGROUND

Implementation strategies are vital for the uptake of evidence to improve health, healthcare delivery, and decision-making. Medical or mental emergencies may be life-threatening, especially in children, due to their unique physiological needs when presenting in the emergency departments (EDs). Thus, practice change in EDs attending to children requires evidence-informed considerations regarding the best approaches to implementing research evidence. We aimed to identify and map the characteristics of implementation strategies used in the emergency management of children.

METHODS

We conducted a scoping review using Arksey and O'Malley's framework. We searched four databases [Medline (Ovid), Embase (Ovid), Cochrane Central (Wiley) and CINAHL (Ebsco)] from inception to May 2019, for implementation studies in children (≤21 years) in emergency settings. Two pairs of reviewers independently selected studies for inclusion and extracted the data. We performed a descriptive analysis of the included studies.

RESULTS

We included 87 studies from a total of 9,607 retrieved citations. Most of the studies were before and after study design (n = 68, 61%) conducted in North America (n = 63, 70%); less than one-tenth of the included studies (n = 7, 8%) were randomized controlled trials (RCTs). About one-third of the included studies used a single strategy to improve the uptake of research evidence. Dissemination strategies were more commonly utilized (n = 77, 89%) compared to other implementation strategies; process (n = 47, 54%), integration (n = 49, 56%), and capacity building and scale-up strategies (n = 13, 15%). Studies that adopted capacity building and scale-up as part of the strategies were most effective (100%) compared to dissemination (90%), process (88%) and integration (85%).

CONCLUSIONS

Studies on implementation strategies in emergency management of children have mostly been non-randomized studies. This review suggests that 'dissemination' is the most common strategy used, and 'capacity building and scale-up' are the most effective strategies. Higher-quality evidence from randomized-controlled trials is needed to accurately assess the effectiveness of implementation strategies in emergency management of children.

The Use of a Pediatric Migraine Practice Guideline in an Emergency Department Setting

OBJECTIVE

The aim of the study was to evaluate the safety and efficacy of a standardized pediatric migraine practice guideline in the emergency department (ED).

METHODS

Migraine Clinical Practice Guideline (MCPG) was created in collaboration with the Division of Pediatric Neurology and Pediatric Emergency Medicine. The MCPG was established on evidence-based data and best practice after a review of the literature. The MCPG was implemented for patients with a known diagnosis of migraine headaches and a verbal numeric pain score (VPS) greater than 6 on a 0 to 10 scale. Patients received intravenous saline, ketorolac, diphenhydramine, and either metoclopramide or prochlorperazine. After 40 minutes, another VPS was obtained, and if no improvement, a repeat dose of metoclopramide or prochlorperazine was administered. If after 40 minutes and minimal pain relief occurred, a consult to neurology was made. A chart review of patients enrolled in the MCPG from April 2004 to April 2013 was conducted. We recorded demographic data, vital signs, ED length of stay, initial VPS, last recorded VPS, adverse events, and admission rate. Nonparametric statistics were performed.

RESULTS

A total of 533 charts were identified with a discharge diagnosis of migraine headache of which 266 were enrolled in the MCPG (179 females and 87 males). Mean (SD) age was 13.9 (3.1). Mean (SD) initial VPS was 7.8 (2.0). Mean (SD) discharge VPS was 2.1 (2.8), representing a 73% reduction of pain. Twenty patients (7.5%) were admitted for status migrainosus; mean (SD) age was 14.0 (3.5) years and mean (SD) VPS was 6.3 (2.8). Mean (SD) length of stay in ED was 283 (107) minutes. No adverse events were identified.

CONCLUSIONS

Our MCPG was clinically safe and effective in treating children with acute migraine headaches. Our data add to the dearth of existing published literature on migraine treatment protocols in the ED setting. We recommend additional prospective and comparative studies to further evaluate the effectiveness of our protocol in this patient population.

Management of pediatric migraine in a tertiary care versus community based emergency department: an observational pilot study

BACKGROUND

Because of a lack of guidelines for the management of pediatric migraine in the emergency department setting, marked variations in treatment protocols exist between institutions. We aimed to characterize differences in management strategies for pediatric migraine treatment between a community-based and a tertiary care emergency department.

METHODS

A retrospective cohort study was performed to include pediatric patients presenting with headache fulfilling the International Classification of Headache Disorders-2 migraine criteria in a tertiary care (site 1) and a community based (site 2) emergency department. The two sites were compared with respect to patient demographics and approach to treatment.

RESULTS

A total of 158 patients at site 1 (mean age 13.6 years, 70% female, 68% African-American) and 63 patients at site 2 (mean age 16.7 years, 71% female, 100% Caucasian) were analyzed. Opiate use (7.6% vs. 33%), imaging (6.3% vs. 20.6%), use of nonsteroidal anti-inflammatory drugs/serotonin agonists at discharge (72.7% vs. 22.2%), and admission rates to hospital (22% vs. 0%) were significantly different. Logistic regression analysis indicated that the main predictors of hospital admission were use of opiates and intravenous combination abortive therapy.

CONCLUSION

Low rates of intravenous combination therapy, antidopaminergic agent, and serotonin agonist use were noted across both hospital settings. Community-based physicians used opiates and obtained neuro-imaging more than those in the academic setting. Standardization of care in the emergency setting coupled with reliable acute care plans that are based on evidenced-based guidelines can allow for better control of episodic migraine and reduce emergency department visits.

Effectiveness of standardized combination therapy for migraine treatment in the pediatric emergency department

OBJECTIVE

To compare outcomes of pediatric migraine patients treated in an emergency department (ED) before and after implementation of a standardized combination intravenous therapy regimen aimed toward improving and standardizing abortive migraine therapy.

BACKGROUND

In a pediatric ED, migraines represent 8-18% of all headache visits. Despite this large number, no standard treatment for acute migraine therapy currently exists.

METHODS

The study utilized a retrospective chart review of patients seeking acute migraine treatment at a tertiary care, pediatric ED from August 2006 to March 2010. Inclusion criteria were pediatric migraine patients as defined by International Headache Society guidelines. The comparison population received various migraine therapies based on attending practice preference. After October 2008, patients received standardized intravenous combination therapy involving a normal saline fluid bolus, ketorolac, prochlorperazine, and diphenhydramine. Occasionally, metoclopramide was substituted during prochlorperazine shortages. Reduction in headache pain score was the primary outcome. Secondary outcome measures included length of ED stay, hospital admission rate, and ED readmission rate within 48 hours.

RESULTS

The study yielded 87 patients who received standardized combination therapy and 165 comparison patients. No significant difference in patient characteristics existed when evaluating patient demographics, outpatient medication use, and initial headache pain score. When compared with the non-standardized therapy population, the combination therapy patients revealed significant reductions in pain score (decrease of 5.3 vs. 6.9, difference -1.6, 95% confidence interval -2.2 to -0.8, P < .001), length of ED stay (5.3 vs. 4.4 hours, difference 0.9, 95% confidence interval 0.2-1.6, P = .008), and hospital admission rate (32% vs. 3%, P < .001) without changes in ED return rate (7% vs. 2%, P = .148).

CONCLUSION

Standardized combination therapy is effective for acute pediatric migraine therapy in the ED by significantly reducing headache pain scores, length of ED stay, and hospital admission rates.
