A Modern Epidemic: Increasing Pediatric Emergency Department Visits and Admissions for Headache

Optimizing Advanced Imaging of the Pediatric Patient in the Emergency Department: Technical Report

Advanced diagnostic imaging modalities, including ultrasonography, computed tomography, and magnetic resonance imaging, are key components in the evaluation and management of pediatric patients presenting to the emergency department. Advances in imaging technology have led to the availability of faster and more accurate tools to improve patient care. Notwithstanding these advances, it is important for physicians, physician assistants, and nurse practitioners to understand the risks and limitations associated with advanced imaging in children and to limit imaging studies that are considered low value, when possible. This technical report provides a summary of imaging strategies for specific conditions where advanced imaging is commonly considered in the emergency department. As an accompaniment to the policy statement, this document provides resources and strategies to optimize advanced imaging, including clinical decision support mechanisms, teleradiology, shared decision-making, and rationale for deferred imaging for patients who will be transferred for definitive care.

Triptans in the Acute Migraine Management of Children and Adolescents: An Update

PURPOSE OF REVIEW

To summarize recent findings regarding triptan use in the acute treatment of pediatric migraine.

RECENT FINDINGS

Prevalence of pediatric migraine is rising. The American Headache Society and American Academy of Neurology updated guidelines to provide evidence-based recommendations for the treatment of acute migraine in youth. In the setting of a dearth of new randomized controlled trials (RCTs), we review current guidelines, triptan use in the emergency department, and an era of secondary analyses. Measuring the efficacy of triptans in pediatric migraine has been challenged by high placebo response rates. Secondary analyses, combining data from multiple RCTs, support that triptans are safe and effective in the treatment of migraine. Triptans are a vital tool and the only FDA-approved migraine-specific treatment available in pediatrics. There is a need for further studies and funding support in pediatric headache medicine.

Optimizing Advanced Imaging of the Pediatric Patient in the Emergency Department: Technical Report

Advanced diagnostic imaging modalities, including ultrasonography, computed tomography, and magnetic resonance imaging (MRI), are key components in the evaluation and management of pediatric patients presenting to the emergency department. Advances in imaging technology have led to the availability of faster and more accurate tools to improve patient care. Notwithstanding these advances, it is important for physicians, physician assistants, and nurse practitioners to understand the risks and limitations associated with advanced imaging in children and to limit imaging studies that are considered low value, when possible. This technical report provides a summary of imaging strategies for specific conditions where advanced imaging is commonly considered in the emergency department.

Clinical Characteristics and Appropriateness of Investigations in Children With Headaches at the Emergency Department

BACKGROUND

Identifying the cause of headaches in pediatric emergency departments (PEDs) can be challenging due to the lack of comprehensive research. This study aims to identify the frequency, characteristics, and unnecessary diagnostic procedures of patients with headaches in the PED setting.

METHODS

A six-month cross-sectional study was conducted at the PED of Alexandria University Children's Hospital, including all children with headaches. Children were classified as having primary headache (PH), secondary benign headache (SBH), and secondary serious headache (SSH) according to predetermined criteria. Logistic regression was employed to analyze the risk factors associated with SSH.

RESULTS

A total of 164 visits to the PED were recorded, out of a total of 22,662 visits, accounting for approximately 0.72% of all visits and 1.17% of the total number of children admitted. PH was the most common cause, accounting for 61.0% of cases, followed by SSH with 24.4%, whereas SBH was the least common with 13.4%. Abnormal neurological examination (odds ratio, 53.752 [1.628 to 1774.442], P = 0.026∗) was found to have a strong and statistically significant association with SSH in the multivariate analysis. Regarding the appropriateness of the investigations conducted, it was found that over half (66.5%) of the cases had unnecessary neuroimaging, with 52% of these cases being children with PH.

CONCLUSIONS

Headaches in children are commonly reported during visits to the PED. PH was the most prevalent, followed by SSH, whereas SBH was the least common. Many of the children received inaccurate first diagnoses and performed unnecessary laboratory tests, neuroimaging, and other tests, mostly electroencephalography.

How Can Specialist Advice Influence the Neuroimaging Practice for Childhood Headache in Emergency Department?

Differentiating between primary and secondary headaches can be challenging, especially in the emergency department (ED). Since symptoms alone are inadequate criteria for distinguishing between primary and secondary headaches, many children with headaches undergo neuroimaging investigations, such as brain CT and MRI. In various studies, the frequency of neuroimaging utilization is influenced by several factors, including teaching status, ownership, metropolitan area, insurance status, and ethnicity of patients. However, only a few studies have considered the role of specialist consultations in ordering neuroimaging studies on childhood headaches. We report the contributions of different specialists to the evaluation of children with headaches admitted to the ED and their influence on neuroimaging decisions. We retrospectively reviewed the medical reports of paediatric patients who presented with headaches to the paediatric ED of the Ospedale Maggiore Policlinico of Milano between January 2017 and January 2022. Overall, 890 children with headaches were evaluated (mean age: 10.0 years; range: 1 to 17 years). All patients were examined by the ED paediatricians, while specialist consultations were required for 261 patients, including 240 neurological (92.0%), 46 ophthalmological (17.6%), and 20 otorhinolaryngological (7.7%) consultations. Overall, 173 neuroimaging examinations were required, of which 51.4 and 48.6% were ordered by paediatricians and neurologists, respectively. In particular, paediatricians required 61.4% of brain CT scans, and neurologists required 92.0% of brain MRI scans. In conclusion, paediatricians were responsible for the management of most children with headaches admitted to the ED, while specialist consultations were required only in about a third of the cases. Although there was no significant difference in the number of neuroimaging studies ordered by specialists, brain CT scans were most often used by paediatricians, and MRI scans by neurologists.

Pediatric headache patient with cerebral abscesses: a brief review of the literature and case report

BACKGROUND

Pediatric headache is a common cause of pediatric emergency department (ED) visits, and 8.8% of cases require imaging. Alarmingly, 12.5% of imaged cases have a pathologic cause. A pediatric patient with a complicated medical history presented to the pediatric ED with multiple cerebral abscesses. The possible causes and contributors to this rare cause of pediatric headache and a review of pediatric headache emergency management are presented.Case Presentation: A 12-year-old male patient with a complex medical and surgical history, including post-repair pulmonary valve stenosis, visited the pediatric ED for intractable and worsening left frontoparietal headache, refractory to ibuprofen, for 6 days. A physical examination revealed severe photophobia and restlessness secondary to severe head pain. Non-contrast brain computed tomography demonstrated two round, bilateral, parietal hypodense lesions with surrounding vasogenic edema. The lesions were consistent with abscesses on magnetic resonance imaging. Eventually, the patient underwent successful surgical abscess drainage and made a full recovery. The patient was lost to follow-up; therefore, no causative bacterial species was determined.

CONCLUSION

Managing pediatric headache in emergency settings requires a robust history and physical examination. Cerebral abscesses are an infrequent but fatal cause of pediatric headache and therefore should be considered among the differential diagnoses.

Sudden onset headaches in paediatric emergency departments: diagnosis and management

Headache is one of the most common pain syndromes in the paediatric population. Headaches are classified as primary (migraine, tension-type headaches, trigeminal autonomic cephalalgia and other primary headaches) or secondary (e.g. post-traumatic). Non-febrile, non-traumatic headaches represent 1% of all paediatric emergency departments (PED) visits. Many patients present with an acute, moderate to severe pain, sometimes with a sudden onset. Sudden onset headache can be the main symptom of life-threatening neurological conditions as well as a sign of primary headaches such as thunderclap or stabbing headaches. This review aims to describe the presentation of sudden primary headaches in children, in order to help the physician to provide effective management in the emergency setting.

Additive Value of Intranasal Fentanyl on Ibuprofen for Pain Management of Children With Moderate to Severe Headaches: A Randomized Controlled Trial

BACKGROUND

Few studies have evaluated the rapid pain improvement provided by medications for children presenting to an emergency department (ED) with headaches.

OBJECTIVE

Our aim was to evaluate pain reduction provided by intranasal fentanyl (INF) compared with placebo in addition to ibuprofen.

METHODS

A single-center, double-blinded, randomized, placebo-controlled clinical trial was conducted in a tertiary care pediatric ED. All children aged 8-17 years presenting with a moderate to severe headache were eligible. Study participants were randomly allocated to receive INF 1.5 µg/kg (maximum dose of 100 µg) or similar placebo solution. Co-administration of oral ibuprofen 10 mg/kg (maximum dose of 600 mg) was also provided. The primary outcome was the mean pain rating reduction at 15 min.

RESULTS

Among the 62 participants, the median age was 14 years (interquartile range [IQR] 12-16 years in both groups) and the median initial visual analog scale (VAS) score was 64 (IQR 55-72 in the intervention group; IQR 50-81 in the control group). There was no difference in the mean pain score reduction at 15 min between the two groups (mean difference 2 mm; 95% CI -7 to 11 mm). Mean VAS score reductions were also similar at 30 and 60 min. Adverse events were more frequent in the INF group (risk ratio 2.8; 95% CI 1.29 to 6.22), but all events were minor and transient. No significant differences were found in other outcomes.

CONCLUSIONS

This study did not find a benefit from INF for providing additional pain relief in children presenting to ED with headaches.

Evolution of Pediatric Migraine Patients Admitted at an Emergency Department after a 10-Year Follow-Up

BACKGROUND

Despite its high prevalence, the clinical course of pediatric migraine has not been fully understood, and previous studies present conflicting results. We present here the findings of a 10-year follow-up study involving children with severe migraine pain admitted to our emergency department. Furthermore, all studies were carried out on selected outpatient clinical case studies. Our aim was to evaluate a population of migraine children admitted to an emergency department because of increased severity or frequency of pain or even because of very anxious parents concerning their child's headache in order to describe their long-term outcomes, whether it differed from that of outpatient populations and to identify possible predictors of prognosis.

METHODS

We recruited 80 subjects with migraine headaches (mean age 8 years with a range of 4-14 years, 50% females), attending the baseline examination of a population admitted for a headache to the Emergency Department in the first half year of 2012. Of the 80 subjects, 48 (60%) were eligible for follow-up in 2022. We included in our study only patients diagnosed with migraine, according to the diagnostic criteria of the International Classification of Headache Disorders. All were contacted by telephone, and a semi-structured questionnaire was provided to them by email. The association between several possible prognostic factors (gender, familiar neurologic disorders, prenatal and perinatal disorders, social activities, sleep disorders, etc.) and the long-term persistence of migraine headaches were explored using logistic regression analysis.

RESULTS

Of 48 subjects with migraine headaches at baseline, 31 (65%) had persistent migraine, and 17 (35%) experienced remission. The preliminary results showed that the presence of neurologic disorders in parents (p < 0.01-odds ratio 9.34 (2.53-41.64) and sleep disorders (p < 0.01-odds ratio 13.18 (2.25-252.74) significantly predicted the 10-year persistence of migraine headaches, while the other considered predictors were found not to influence prognosis.

CONCLUSIONS

To our knowledge, this was the first study conducted on a selected pediatric population upon admission to the emergency room. Our study suggests that a population of pediatric migraine selected for admission to the emergency department also shows a favorable long-term prognosis, like the studies conducted in the outpatient sample. Familial neurological comorbidity and sleep disorders were unfavorable factors for predicting good outcomes.

Olfactory training reduces pain sensitivity in children and adolescents with primary headaches

Objective

Headache prevalence among children and adolescents has increased over the last few years. Evidence-based treatment options for pediatric headaches remain limited. Research suggests a positive influence of odors on pain and mood. We investigated the effect of repeated exposure to odors on pain perception, headache-related disability, and olfactory function in children and adolescents with primary headaches.

Methods

Eighty patients with migraine or tension-type headache (mean 13.1 ± 3.29 years) participated, of whom 40 underwent daily olfactory training with individually selected pleasant odors for 3 months and 40 received state-of-the-art outpatient therapy as a control group. At baseline and after a 3-month follow-up, olfactory function [odor threshold; odor discrimination; odor identification; comprehensive Threshold, Discrimination, Identification (TDI) score], mechanical detection and pain threshold (quantitative sensory testing), electrical pain threshold, patient-reported outcomes on headache-related disability [Pediatric Migraine Disability Assessment (PedMIDAS)], pain disability [Pediatric Pain Disability Index (P-PDI)], and headache frequency were assessed.

Results

Training with odors significantly increased the electrical pain threshold compared to the control group (U = 470.000; z = -3.177; p = 0.001). Additionally, olfactory training significantly increased the olfactory function (TDI score [t(39) = -2.851; p = 0.007], in particular, olfactory threshold, compared to controls (U = 530.500; z = -2.647; p = 0.008). Headache frequency, PedMIDAS, and P-PDI decreased significantly in both groups without a group difference.

Conclusions

Exposure to odors has a positive effect on olfactory function and pain threshold in children and adolescents with primary headaches. Increased electrical pain thresholds might reduce sensitization for pain in patients with frequent headaches. The additional favorable effect on headache disability without relevant side effects underlines the potential of olfactory training as valuable nonpharmacological therapy in pediatric headaches.

Red flags Presented in Children Complaining of Headache in Paediatric Emergency Department

This study aimed to determine how common are specific red flags of life-threatening headache (LTH) among children with complaints of headache in the emergency department. A retrospective study was conducted over five years, including all patients aged < 18 years who presented for a headache to a Pediatric Emergency Department. We identified patients with life-threatening headaches and compared the recurrence of the main red flags (occipital location, vomit, nocturnal wake-up, presence of neurological signs, and family history of primary headache) to the remaining sample. Two-thousand-fifty-one children (51% female, 49% male) were included. Seven patients (0.3%) were diagnosed with a life-threatening headache. In the analysis of red flags, only the presence of abnormal neurological evaluation and vomiting was found to be more common in the LTH sample. No statistically significant difference was found for nocturnal awakening or occipital localization of pain. Urgent neuroradiological examinations were performed in 72 patients (3.5% of cases). The most common discharge diagnosis was infection-related headache (42.4%), followed by primary headaches (39.7%). This large retrospective study confirms the most recent literature suggesting that night awakenings and occipital pain are common symptoms also associated with not-LTH. Therefore, if isolated, they should not be considered red flags.

Sumatriptan as a First-Line Treatment for Headache in the Pediatric Emergency Department

BACKGROUND

Headache is a common presenting condition for patients seen in the pediatric emergency department (ED). Intranasal (IN) sumatriptan is a well-tolerated and safe abortive treatment for migraine headache, but it is infrequently administered in pediatric EDs. In this study we characterize an ED migraine pathway that uses IN sumatriptan as a first-line treatment.

METHODS

We performed retrospective chart analysis from a single center, reviewing a cohort of patients treated on an ED migraine pathway between October 2016 and February 2020. We reviewed patient demographics, clinical characteristics, treatment patterns, change in pain scores, sumatriptan prescriptions at discharge, length of stay (LOS), ED charges, and unexpected return visits.

RESULTS

A total of 558 patients (aged six to 21 years, 66% female) were included in this study. Overall, the median pretreatment pain score was 7 (interquartile range [IQR]: 5 to 8) and the median post-treatment pain score was 2 (IQR: 0 to 4). Forty-eight percent of patients received IN sumatriptan in the ED, and 36% of those who received sumatriptan were prescribed oral sumatriptan at discharge. When intravenous (IV) access was obtained for headache management, this was associated with a significantly longer LOS and higher ED charges.

CONCLUSIONS

IN sumatriptan shows promise as a feasible and potentially effective first-line treatment for pediatric migraine in the ED that could reduce the need for IV therapies, shorten LOS, and lower ED charges. Further research is needed to determine the efficacy of IN sumatriptan relative to other common first-line therapies used to treat pediatric migraine in the ED.

Disparities in the emergency department management of pediatric migraine by race, ethnicity, and language preference

BACKGROUND

There are disparities in pain management for children presenting to the emergency department (ED) according to their racial and ethnic backgrounds. It is not known if there are differences in the treatment of pain associated with pediatric migraines by race, ethnicity, and language for care (REaL).

METHODS

We analyzed treatment patterns and outcomes in our ED for acute migraine in pediatric patients by REaL. Retrospective data on treatments, length of stay (LOS), and charges were collected from the electronic medical record for pediatric patients on the ED migraine pathway from October 2016 to February 2020. Patient race/ethnicity and language for care were self-reported at registration. We analyzed two treatment groups: receipt of oral (PO) or intranasal (IN) medications only or intravenous (IV) ± IN/PO medications. A total of 833 patients (median age 14.8 years, interquartile range [IQR] 12.3-16.5 years; 67% female, 51% non-Hispanic White (nHW), 23% Hispanic, 8.3% Black or African American, 4.3% Asian) were included. A total of 287 received PO/IN medications only and 546 received IV medications.

RESULTS

Initial pain scores in the two groups were similar. Patients who were Asian, Black or African American, and Hispanic or had a language for care other than English (LOE) had significantly lower odds of receiving IV treatment, while patients who were nHW and preferred English had higher odds of receiving IV treatment. The IV treatment group had longer LOS and ED charges. Pediatric ED patients with migraine who were Black, Asian, and Hispanic or had a LOE had a decreased likelihood of receiving IV therapies while patients who were nHW were more likely to receive IV treatments, despite similar initial pain scores.

CONCLUSIONS

These data align with previous studies on pain management disparities and highlight another area where we must improve equity for patients in the ED.

Generalized Anxiety Disorder: A Predictor for Poor Responsiveness to Botulinum Toxin Type A Therapy for Pediatric Migraine

BACKGROUND

To assess the efficacy, safety, and predictors for poor responsiveness of botulinum toxin type A (BoNT-A) for chronic migraine in the adolescent and young adult population.

METHODS

A retrospective analysis of 56 patients who received BoNT-A for chronic migraine with an age range from 13 to 21 years was performed. Of 56 patients, 34 were enrolled in the study based on the inclusion criterion. Patients who received three dosages of BoNT-A were assessed at nine months from the first injection. Variables including age, body mass index, headache intensity, frequency, character, and side effects were assessed. The patients were divided into two groups based on response to BoNT-A therapy, responders and nonresponders.

RESULTS

Overall among the 34 patients enrolled in the study, the average headache frequency decreased from 18.6 of 28 to 9.9 of 28 days, P value, <0.001 from baseline. There was significant decrease in the average headache intensity, 8.1 to 4.3. Of 34 patients, 25 (73%) patients responded to treatment with decrease in headache frequency by ≥ 50% from the baseline. Among the nonresponder patients, a significant number of patients (six of nine, 67%) had generalized anxiety disorder with Generalized Anxiety Disorder-7 score greater than 15 versus the responder group (six of 25, 24%, P value 0.040).

CONCLUSIONS

BoNT-A remains a safe and effective therapy for adolescent and young adult patients with chronic migraines at nine months of follow-up. Generalized anxiety disorder with Generalized Anxiety Disorder-7 score greater than 15 can be a major predictor of poor response to this therapy.

Reversible cerebral vasoconstriction syndrome in children: an update

Headaches are one of the most common neurologic complaints leading to emergency room visits in pediatric patients. Of the different type of headache presentations, thunderclap headaches require a particularly urgent work-up. In children, recurrent thunderclap headaches are more often associated with reversible cerebral vasoconstriction syndrome (RCVS) than other etiologies such as subarachnoid hemorrhage. RCVS is a vascular disorder of incompletely understood etiology, characterized by diffuse vasoconstriction of the cerebral arterial vasculature, and commonly associated with recurrent severe headaches. Patients may experience focal neurological deficits, due to hemorrhages, infarcts, and even posterior reversible encephalopathy syndrome . Although RCVS has been best characterized in adults, it does occur in children. This review summarizes the presentation of RCVS in children and highlights some of the differences with the adult population.

Pediatric Headache Attributed to Infection

Pediatric headaches attributed to infection are typically related to non-life threatening illnesses such as upper respiratory tract infections and rhinosinusitis. Although less common, secondary headaches related to life threatening infections are most frequently associated with meningitis. This review provides an overview of the International Classification of Headache Disorders third edition (ICHD-3) categories of infections contributing to secondary headache, describes clinical presentation, and presents a focused review on relevant diagnoses associated with this headache type. An understanding of headache attributed to infection will provide the foundation on distinguishing secondary headaches from various etiological infectious disorders.

Rates and Predictors of Using Opioids in the Emergency Department to Treat Migraine in Adolescents and Young Adults

OBJECTIVES

This study aimed to determine the rate and context in which opioids are used to treat migraine in adolescents and young adults seen in emergency care settings.

METHODS

Data from 2010 to 2016 in the Cerner Health Facts electronic health record data warehouse were analyzed using multilevel logistic regression to estimate the population likelihood of an opioid being used in the emergency department (ED) to treat a primary diagnosis of migraine in adolescents and young adults and to evaluate the extent to which this likelihood varies as a function of characteristics of the patient (age, sex, race, and insurance), encounter (referral source, provider specialty, and encounter duration and year), and ED (region, setting, size, payer mix, and academic status).

RESULTS

The study identified 14,494 eligible ED encounters with unique patients, of which 23% involved an opioid. Likelihood of being treated with opioids was significantly higher for patients who were older, female, white, and seen by a surgeon and who had longer encounters and encounters earlier in the time period sampled. Sites varied widely in percentage of encounters involving opioids (mean, 26.4% ± 20.1%; range, 0-100%), with higher rates associated with smaller sites with relatively higher proportions of commercially insured patients.

CONCLUSIONS

Use of opioids in the ED to treat migraine in youth is fairly common, with rate variation reflecting broader trends in for whom opioids tend to be more likely to be prescribed. These findings may be helpful for benchmarking and informing quality improvement efforts aimed at reducing unwarranted opioid exposure in youth.

Management of Neurological Emergencies in Children: An Updated Overview

Neurological emergencies account for about one-third of the highest severity codes attributed in emergency pediatric departments. About 75% of children with acute neurological symptoms presents with seizures, headache, or other paroxysmal events. Life-threatening conditions involve a minor proportion of patients (e.g., less than 15% of children with headache and less than 5% of children with febrile seizures). This review highlights updated insights about clinical features, diagnostic workup, and therapeutic management of pediatric neurological emergencies. Particularly, details will be provided about the most recent insights about headache, febrile seizures, status epilepticus, altered levels of consciousness, acute motor impairment, acute movement disorders, and functional disorders, as well as the role of diagnostic tools (e.g., neuroimaging, lumbar puncture, and electroencephalography), in the emergency setting. Moreover, the impact of the current novel coronavirus disease2019 (COVID-19) pandemic on the evaluation of pediatric neurologic emergencies will also be analyzed.

Efficacy of a pediatric headache infusion center: A single-center experience

OBJECTIVE

To evaluate the efficacy of a pediatric headache infusion center (HIC) in alleviating the symptoms and preventing future visits to the emergency department (ED).

BACKGROUND

Headache is a common reason for visits to the pediatric ED. ED visits are associated with inordinate costs of care and are conceived by parents to be avoidable if adequate alternatives are available. An infusion center for acute treatment of intractable headache in children with chronic migraine may be an effective alternative to an ED visit.

METHODS

This was a retrospective analysis of data from a single-center cohort of patients with a known history of chronic migraine, presenting to Dayton Children's HIC with an acute migraine from June 1, 2017 to June 1, 2020. Patients were treated according to established protocols divided into two pathways. Patient demographics, clinical characteristics, pre- and postinfusion pain scores, ED visits and inpatient admissions within 2 weeks of HIC visit, and ED visits 1 year prior and 1 year after the HIC visit were noted.

RESULTS

A total of 297 HIC visits were analyzed from 201 patients. The HIC was effective in controlling symptoms with a significant reduction in pain score (median [interquartile range; IQR] 7.0 [2.0] preinfusion vs. 1.0 [2.0] postinfusion, p < 0.001). Only 25/297 (8.4%) patients came to the ED within 2 weeks of the HIC visit, and an even smaller number of patients (20/297, 6.7%) were admitted as inpatients within 2 weeks of the HIC visit. The number of ED visits was significantly reduced in the year after the HIC visit compared with the year prior (median [IQR] 1.0 [2.0] before vs. 0.0 [1.0] after, p < 0.001).

CONCLUSION

A pediatric HIC is effective in alleviating the symptoms and preventing ED visits. These centers should be considered as standard of care at children's hospitals.

Standardized Headache Therapy in the Pediatric Emergency Department Using Improvement Methodology

Supplemental Digital Content is available in the text.

Introduction:

Primary headache is a common cause of pediatric emergency department (PED) visits. Without published guidelines to direct treatment options, various strategies lacking evidence are often employed. This study aims to standardize primary headache treatment in the PED by promoting evidence-based therapies, reducing nonstandard abortive therapies, and introducing dihydroergotamine (DHE) into practice.

Methods:

A multidisciplinary team developed key drivers, created a clinical care algorithm, and updated electronic medical record order sets. Outcome measures included the percentage of patients receiving evidence-based therapies, nonstandard abortive therapies, DHE given after failed first-line therapies, and overall PED length of stay. Process measures included the percent of eligible patients with the order set usage and medications received within 90 minutes. Balancing measures included hospital admissions and returns to the PED within 72 hours. Annotated control charts depicted results over time.

Results:

We collected data from July 2017 to December 2019. The percent of patients receiving evidence-based therapies increased from 69% to 73%. The percent of patients receiving nonstandard abortive therapies decreased from 2.5% to 0.6%. The percent of patients receiving DHE after failed first-line therapies increased from 0% to 37.2%. No untoward effects on process or balancing measures occurred, with sustained improvement for 14 months.

Conclusion:

Standardization efforts for patients with primary headaches led to improved use of evidence-based therapies and reduced nonstandard abortive therapies. This methodology also led to improved DHE use for migraine headache resistant to first-line therapies. We accomplished these results without increasing length of stay, admission, or return visits.

Association of Bacteremia with Vaccination Status in Children Aged 2 to 36 Months

OBJECTIVE

To determine the association between bacteremia and vaccination status in children aged 2-36 months presenting to a pediatric emergency department.

STUDY DESIGN

Retrospective cohort study of children aged 2-36 months with blood cultures obtained in the pediatric emergency department between January 2013 and December 2017. The exposure of interest was immunization status, defined as number of Haemophilus influenzae type B (Hib) and Streptococcus pneumoniae vaccinations, and the main outcome positive blood culture. Subjects with high-risk medical conditions were excluded.

RESULTS

Of 5534 encounters, 4742 met inclusion criteria. The incidence of bacteremia was 1.5%. The incidence of contaminated blood culture was 5.0%. The relative risk of bacteremia was 0.79 (95% CI 0.39-1.59) for unvaccinated and 1.20 (95% CI 0.52-2.75) for undervaccinated children relative to those who had received age-appropriate vaccines. Five children were found to have S pneumoniae bacteremia and 1 child had Hib bacteremia; all of these subjects had at least 3 sets of vaccinations. No vaccine preventable pathogens were isolated from blood cultures of unvaccinated children. We found no S pneumoniae or Hib in children 2-6 months of age who were not fully vaccinated due to age (95% CI 0-0.13%) and the contamination rate in this group was high compared with children 7-36 months (6.6% vs 3.7%).

CONCLUSIONS

Bacteremia in young children is an uncommon event. Contaminated blood cultures were more common than pathogens. Bacteremia from S pneumoniae or Hib is uncommon and, in this cohort, was independent of vaccine status.

Rates of Presentation, Treatments and Serious Neurologic Disorders Among Children and Young Adults Presenting to US Emergency Departments With Headache

OBJECTIVE

To evaluate rates of presentation, neuroimaging, therapies, and serious neurologic disorders (SNDs) among children and young adults presenting to the emergency department with headache.

METHODS

We performed a cross-sectional study of a nationally representative sample survey of visits to US emergency departments between 2002 and 2017. We identified encounters of patients ≤25 years old with chief complaint of headache. We report the rates of presentation, imaging, and treatments and report proportions having concomitant diagnoses of serious neurologic disorders.

RESULTS

Among encounters ≤25 years, 2.0% had a chief complaint of headache, with no change in the yearly rates of encounters (P = .98). Overall, 20.8% had a head computed tomography (CT), with a reduction in performance between 2007 and 2016 (P < .01). One-quarter (25.2%, 95% confidence interval [CI] 22.2%-28.3%) were given narcotics and 2.5% (95% CI 1.7%-3.2%) had serious neurologic disorders.

CONCLUSION

Overall, 2.0% of emergency department encounters among patients ≤25 years were for headache, with low rates of serious neurologic disorders. CT use appeared to be declining.

Multivariate analysis of the impact of weather and air pollution on emergency department visits for night-time headaches among children: retrospective, clinical observational study

OBJECTIVES

To examine the association between the number of visits to the emergency department (ED) by children for night-time headaches and exposure to multifaceted factors, such as meteorological conditions and air pollution.

DESIGN

We conducted a clinical observational time-series analysis study.

SETTING

We reviewed consecutive patients younger than 16 years of age at the primary ED centre in Kobe city, Japan, during the night shift (19:30-7:00 hours) between 1 January 2011 and 31 December 2019.

PARTICIPANTS

In total, 265 191 children visited the ED; 822 presented with headache during the study period.

PRIMARY OUTCOME MEASURES

We investigated the effects of meteorological factors and air pollutants by multivariate analysis of Poisson regression estimates. A subanalysis included the relationship between the number of patients with night-time headaches and the above factors by sex. Furthermore, the effect of typhoon landing on patient visits for headache was also analysed. Headache was not classified because examinations were performed by general paediatricians (non-specialists).

RESULTS

The number of patients with night-time headaches displayed distinct seasonal changes, with peaks during the summer. Multivariate analysis of Poisson regression estimates revealed a significant positive relationship between the number of patients for headache and mean temperature. Subanalysis by sex indicated a positive relationship between the number of patients with headache and mean temperature in both sexes; however, it was significant only for females. No relationship was found between the number of patients with headache and air pollution. There was no change in the number of patients for night-time headaches 3 days before and after typhoon landing.

CONCLUSIONS

High temperature is the main factor for visiting ED for night-time headaches among children in Kobe city. Our results suggest that preventive measures against night-time headaches may be possible by reducing time spent outside during summer.

STUDY SELECTION

Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Full-text, peer-reviewed journal publications from 1994 to 2020 in English; focus on acute sphenoid sinusitis; pediatric patients (<18 years of age); series with two or more children. Studies were assessed for data including demographics, presenting symptoms and signs, radiological investigations, treatment, outcomes and complications.

RESULTS

Ten studies identifying 71 patients were included. Average age at presentation was 12.0 years (range 5-17 years). M:F ratio 1:1. The most common presenting symptoms were headache (98.6%), fever (50.7%), nasal symptoms (22.5%) ocular symptoms (19.7%) and decreased level of consciousness (12.7%). Twenty patients (28.1%) had neurological signs. Twenty-three patients (32.4%) presented with headache in isolation. Unsuspected diagnosis at presentation was noted in 54.0%. Average time to initial presentation was 14.0 days (median = 5.5 days, range 1-90 days). The majority of children were treated with antibiotics (98.6%) with 31.0%, 2.8% and 2.8% also undergoing sinus surgery, revision sinus surgery and neurosurgery, respectively. Intracranial complications occurred in 16.9% of patients. Significant long term sequelae occurred in 2 children (2.8%) and one death (1.4%) was also reported.

LIMITATIONS

All studies were retrospective case note reviews.

CONCLUSIONS

Acute sphenoid sinusitis is a rare and difficult condition to diagnose in children. The majority of patients make a full recovery with appropriate treatment. If treatment is delayed however consequences can be life-threatening.

Serious Diagnoses for Headaches After ED Discharge

BACKGROUND

Headache is a common complaint among children presenting to the emergency department (ED) and can be due to serious neurologic and nonneurologic diagnoses (SNNDs). We sought to characterize the children discharged from the ED with headache found to have SNNDs at revisits.

METHODS

We performed a multicenter retrospective cohort study using data from 45 pediatric hospitals from October 1, 2015, to March 31, 2019. We included pediatric patients (≤18 years) discharged from the ED with a principal diagnosis of headache, excluding patients with concurrent or previous SNNDs or neurosurgeries. We identified rates and types of SNNDs diagnosed within 30 days of initial visit and compared these rates with those of control groups defined as patients with discharge diagnoses of cough, chest pain, abdominal pain, and soft tissue complaints.

RESULTS

Of 121 621 included patients (57% female, median age 12.4 years, interquartile range: 8.8-15.4), 608 (0.5%, 95% confidence interval: 0.5%-0.5%) were diagnosed with SNNDs within 30 days. Most were diagnosed at the first revisit (80.8%); 37.5% were diagnosed within 7 days. The most common SNNDs were benign intracranial hypertension, cerebral edema and compression, and seizures. A greater proportion of patients with SNNDs underwent neuroimaging, blood, and cerebrospinal fluid testing compared with those without SNNDs (P < .001 for each). The proportion of SNNDs among patients diagnosed with headache (0.5%) was higher than for control cohorts (0.0%-0.1%) (P < .001 for each).

CONCLUSIONS

A total 0.5% of pediatric patients discharged from the ED with headache were diagnosed with an SNND within 30 days. Further efforts to identify at-risk patients remain a challenge.

Epidemiology of Headache in Children and Adolescents-Another Type of Pandemia

PURPOSE OF REVIEW

Headaches are not only responsible for restrictions in everyday life in adults. In children and adolescents, regular headaches lead also to reduced life quality and limitations in the social sphere, in school education, and in professional careers. Here, we provide an overview on the frequency of headache in children and adolescents with the aim of increasing awareness about this particular health issue.

RECENT FINDINGS

Overall, headache prevalence in children and adolescents has been increasing in recent years. From various regions worldwide, data describing headache, its forms, and consequences are growing. In addition, factors frequently correlated with headache are repeatedly investigated and named: besides genetic factors, psychosocial and behavioral factors are linked to the prevalence of headache. Increasing evidence indicates that headache is underestimated as a common disorder in children and adolescents. Accordingly, too little emphasis is placed by society on its prevention and treatment. Thus, the extent of the social and health economic burden of frequent headaches in children and adolescents needs to be better illustrated, worldwide. Furthermore, the data collected in this review should support the efforts to improve outpatient therapy paths for young headache patients. Factors correlating with headache in pupils can draw our attention to unmet needs of these patients and allow physicians to derive important therapy contents from this data.

Primary Care Access to an Online Decision Support Tool is Associated With Improvements in Some Aspects of Pediatric Migraine Care

OBJECTIVE

To evaluate whether primary care provider (PCP) access to an online decision support tool is associated with a change in evidence-based primary care medical management of pediatric migraine.

METHODS

In this prospective observational study, PCPs serving a target community were educated on the availability and use of an online clinical decision support tool that was developed to inform treatment of pediatric migraine. For 9 months before and after implementation of the decision tool, the proportions of children with migraine prescribed evidence-based and contraindicated medications by PCPs in the target region were monitored using electronic medical record query and statistically compared to these same proportions for patients in surrounding (control) regions. Rates of visits to the emergency department for migraine also were tracked pre- and postimplementation as an indirect measure of impact of the decision tool. Provider usage of the decision tool was monitored and summarized using web analytics.

RESULTS

Approximately half (56%) of target region PCPs used the online tool at least once over the project period. Relative to control regions and baseline trends, the proportion of children residing in the target region who were prescribed recommended abortive and preventive medications for treating migraine was statistically significantly higher following implementation of the tool. No significant changes to frequency of emergency care visits for migraine by youth in the target region were observed.

CONCLUSIONS

Availability to PCPs of an online decision support tool for pediatric migraine is associated with a modest change in some aspects of evidence-based medical care.

Evaluation and Treatment of Primary Headaches in Adolescents

Headache is a common episodic and chronic pain syndrome in adolescents. Evaluation of headaches in primary care requires a comprehensive assessment including lifestyle behaviors and physical examination, as well as an understanding of when to pursue appropriate testing. Primary headache disorders seen in adolescents include migraine and tension-type headache. Pharmacologic management for primary headache includes both acute and prophylactic treatment strategies.

[Headache, abdominal and back pain in children and adolescents in Germany : Results from KiGGS Wave 2 and trends]

BACKGROUND

Pain not only causes suffering in children and adolescents, but also leads to school absenteeism, medication intake, medical treatment, and an increased risk of recurrent pain in adulthood.

OBJECTIVES

Based on data from the nationwide German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-2017), the 3‑month prevalence of recurrent headache, abdominal and back pain in girls and boys is reported, and is compared with the prevalence from the KiGGS baseline survey (2003-2006). The consequences of recurrent headache were also explored.

MATERIALS AND METHODS

Data from >11,000 participants (KiGGS Wave 2) and from >12,000 (KiGGS baseline) participants aged between 3 and 17 years were analyzed. For 3‑ to 10-year-olds, parents/guardians answered the questions, while 11- to 17-year-olds provided information themselves.

RESULTS

In 3‑ to 10-year-olds, recurrent abdominal pain was most prevalent, affecting one third of girls and one quarter of boys. Headache was the most frequent type of pain in 11- to 17-year-olds, affecting almost every second girl and about every third boy. The 3‑month prevalence of recurrent headache, abdominal and back pain has increased in girls and boys, especially in the age groups 7 to 10 years and 11 to 13 years. Among recurrent headache sufferers, adolescents take medication almost twice as often as children.

CONCLUSIONS

Headache, abdominal, and back pain are still and with increasing prevalence very common symptoms in children and adolescents in Germany. Their prevention requires a holistic view of children's health in the psychosocial living environment, and healthcare context.
