Initiation of maintenance antiinflammatory medication in asthmatic children in a pediatric emergency department

Acute Asthma in the Pediatric Emergency Department: Infections Are the Main Triggers of Exacerbations

Background

Asthma exacerbations are a common reason for Emergency Department (ED) visits in children.

Aim

To analyze differences among age groups in terms of triggering factors and seasonality and to identify those with higher risk of severe exacerbations.

Methods

We retrospectively revised the files of children admitted for acute asthma in 2016 in our Pediatric ED.

Results

Visits for acute asthma were 603/23197 (2.6%). 76% of the patients were <6 years old and 24% ≥6. Infections were the main trigger of exacerbations in both groups; 33% of the school-aged children had a triggering allergic condition (versus 3% in <6 years; p < .01). 191 patients had a previous history of asthma; among them, 95 were ≥6 years, 67% of whom were not using any controller medication, showing a higher risk of a moderate-to-severe exacerbation than those under long-term therapy (p < .01). Exacerbations peaked in autumn and winter in preschoolers and in spring and early autumn in the school-aged children.

Conclusions

Infections are the main trigger of acute asthma in children of any age, followed by allergy in the school-aged children. Efforts for an improved management of patients affected by chronic asthma might go through individualized action plans and possibly vaccinations and allergen-avoidance measures.

Initiation of an Inhaled Corticosteroid During a Pediatric Emergency Visit for Asthma: A Randomized Clinical Trial

STUDY OBJECTIVE

We determine whether prescribing an inhaled corticosteroid during a pediatric emergency department (ED) asthma visit increases ongoing use and improves outcomes.

METHODS

This randomized trial enrolled children aged 1 to 18 years, with persistent asthma not previously prescribed a controller medication, and who were being discharged after ED asthma treatment. Intervention subjects received a 1-month prescription for an inhaled corticosteroid (fluticasone or budesonide by age) in addition to standard asthma therapy and instructions given to all patients. Outcomes included filling of the intervention and subsequent inhaled corticosteroid prescriptions, asthma-related symptoms and quality of life, and follow-up rates with a primary care provider. Outcomes were assessed during telephone interviews 2 and 8 weeks after the ED visit and by review of primary care provider and pharmacy records.

RESULTS

One hundred forty-seven children were enrolled, and baseline measures were similar between groups. In the intervention group, 53.5% of patients filled an initial ED prescription for inhaled corticosteroid. There was no important difference between groups in subsequent filling of a primary care provider prescription (21% intervention versus 17% control; relative rate=1.24; 95% confidence interval 0.63 to 2.41). During the 2 weeks after the ED visit, intervention subjects reported reduced shortness of breath while awake and cough while asleep compared with controls. Groups did not differ by rates of primary care provider follow-up, functional limitations, or asthma-related symptoms and quality of life.

CONCLUSION

There was no difference in the proportion of patients who filled a primary care provider prescription after ED initiation of an inhaled corticosteroid. The intervention was associated with reduced reported symptoms but did not affect other asthma outcomes or primary care provider follow-up.

Pediatric acute asthma exacerbations: Evaluation and management from emergency department to intensive care unit

OBJECTIVE

The goal of this report is to review available modalities for assessing and managing acute asthma exacerbations in pediatric patients, including some that are not included in current expert panel guidelines. While it is not our purpose to provide a comprehensive review of the National Asthma Education and Prevention Program (NAEPP) guidelines, we review NAEPP-recommended treatments to provide the full range of treatments available for managing exacerbations with an emphasis on the continuum of care between the ER and ICU.

DATA SOURCES

We searched PubMed using the following search terms in different combinations: asthma, children, pediatric, exacerbation, epidemiology, pathophysiology, guidelines, treatment, management, oxygen, albuterol, β2-agonist, anticholinergic, theophylline, corticosteroid, magnesium, heliox, BiPAP, ventilation, mechanical ventilation, non-invasive mechanical ventilation and respiratory failure. We attempted to weigh the evidence using the hierarchy in which meta-analyses of randomized controlled trials (RCTs) provide the strongest evidence, followed by individual RCTs, followed by observational studies. We also reviewed the NAEPP and Global Initiative for Asthma expert panel guidelines.

RESULTS AND CONCLUSIONS

Asthma is the most common chronic disease of childhood, and acute exacerbations are a significant burden to patients and to public health. Optimal assessment and management of exacerbations, including appropriate escalation of interventions, are essential to minimize morbidity and prevent mortality. While inhaled albuterol and systemic corticosteroids are the mainstay of exacerbation management, escalation may include interventions discussed in this review.

Adherence to common cardiovascular medications in patients with schizophrenia vs. patients without psychiatric illness

OBJECTIVE

The purpose of the study was to examine whether individuals with diagnoses of schizophrenia were differentially adherent to their statin or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) medications compared to individuals without psychiatric illness.

METHOD

Using electronic medical record data across 13 Mental Health Research Network sites, individuals with diagnoses of schizophrenia or schizoaffective disorder receiving two or more medication dispensings of a statin or an ACEI/ARB in 2011 (N=710) were identified and matched on age, sex and Medicare status to controls with no documented mental illness and two or more medication dispensings of a statin in 2011 (N=710). Medication adherence, and sociodemographic and clinical characteristics of the study population were assessed.

RESULTS

Multivariable models indicated that having a schizophrenia diagnosis was associated with increased odds of statin medication adherence; the odds ratio suggested a small effect. After adjustment for medication regimen, schizophrenia no longer showed an association with statin adherence. Having a schizophrenia diagnosis was not associated with ACEI/ARB medication adherence.

CONCLUSIONS

Compared to patients without any psychiatric illness, individuals with schizophrenia were marginally more likely to be adherent to their statin medications. Given that patterns of adherence to cardioprotective medications may be different from patterns of adherence to antipsychotic medications, improving adherence to the former may require unique intervention strategies.

Pediatricians Support Initiation of Asthma Controller Medications in the Emergency Department: A National Survey

OBJECTIVES

Although National Asthma Guidelines recommend that emergency department (ED) physicians consider initiating controller medications, research suggests that this practice occurs infrequently. The goal of this study was to assess primary care pediatricians' (PCP) beliefs and attitudes regarding ED initiation of controller medications for children with persistent asthma symptoms.

METHODS

This was a cross-sectional mail survey of a randomly selected national sample of pediatricians from the American Academy of Pediatrics. The survey posed questions regarding beliefs, barriers, and support for national guideline recommendations.

RESULTS

Eight hundred eighty-six (44.3%) of 2000 subjects responded. Five hundred seventy-two (64.5%) respondents met eligibility for analysis. When presented with a vignette of a child with persistent asthma, 476 (83%) of PCPs felt it was appropriate for the ED physician to initiate controller medications. Most (80%) PCPs supported the national guideline recommendation, although a similar proportion reported they have never or rarely experienced this practice before. Only 11% opposed the practice in all circumstances. Beliefs supporting this practice included the following: opportunity to capture patients lost to follow-up (85%), reinforcement of daily use of controller medications (83%), and controller medication may shorten an acute exacerbation (53%). Barriers included lack of time for education in ED (65%), reinforcement of ED use for primary care (64%), lack of PCP communication (62%), and inability to assess severity appropriately (41%). Most (90%) PCPs expect communication from the ED provider.

CONCLUSIONS

A majority of pediatricians support the practice of ED physicians initiating controller medication during an acute visit for asthma. Communication with the PCP, appropriate screening of severity, and education about controller medications were important considerations expressed by these providers.

A systematic review of the implementation and impact of asthma protocols

BACKGROUND

Asthma is one of the most common childhood illnesses. Guideline-driven clinical care positively affects patient outcomes for care. There are several asthma guidelines and reminder methods for implementation to help integrate them into clinical workflow. Our goal is to determine the most prevalent method of guideline implementation; establish which methods significantly improved clinical care; and identify the factors most commonly associated with a successful and sustainable implementation.

METHODS

PUBMED (MEDLINE), OVID CINAHL, ISI Web of Science, and EMBASE.

STUDY SELECTION

Studies were included if they evaluated an asthma protocol or prompt, evaluated an intervention, a clinical trial of a protocol implementation, and qualitative studies as part of a protocol intervention. Studies were excluded if they had non-human subjects, were studies on efficacy and effectiveness of drugs, did not include an evaluation component, studied an educational intervention only, or were a case report, survey, editorial, letter to the editor.

RESULTS

From 14,478 abstracts, we included 101 full-text articles in the analysis. The most frequent study design was pre-post, followed by prospective, population based case series or consecutive case series, and randomized trials. Paper-based reminders were the most frequent with fully computerized, then computer generated, and other modalities. No study reported a decrease in health care practitioner performance or declining patient outcomes. The most common primary outcome measure was compliance with provided or prescribing guidelines, key clinical indicators such as patient outcomes or quality of life, and length of stay.

CONCLUSIONS

Paper-based implementations are by far the most popular approach to implement a guideline or protocol. The number of publications on asthma protocol reminder systems is increasing. The number of computerized and computer-generated studies is also increasing. Asthma guidelines generally improved patient care and practitioner performance regardless of the implementation method.

Initiating inhaled steroid treatment for children with asthma in the emergency room: current reported prescribing rates and frequently cited barriers

OBJECTIVE

The objective of this study was to determine how frequently emergency department (ED) physicians prescribe inhaled corticosteroids (ICSs) and describe commonly cited barriers.

METHODS

We surveyed members of the American Academy of Pediatrics Section on Emergency Medicine between May and August 2011. Demographic data were collected. Using the knowledge-attitude-behavior model for barriers to physician guideline adherence, we asked 20 Likert scale questions regarding barriers to ICS prescribing. Our primary outcome was reported frequency of ICS prescribing. We defined frequent prescribers as those who prescribe ICS more than 25% of the time. Logistic regression models were built for each barrier category and identified barriers that predict infrequent prescribing.

RESULTS

Two hundred seven (19.5%) of the 1062 surveyed responded; 75.8% report prescribing ICS 25% of the time or less. For knowledge, those who agreed that the National Heart, Lung, and Blood Institute guidelines are not clear regarding the ED physician's role were less likely to be frequent prescribers compared with those who disagreed (adjusted odds ratio [OR], 0.31; 95% confidence interval [CI], 0.11-0.90). For attitude, those who agreed it is not the role of the ED physician to prescribe long-term medications were less likely to be frequent prescribers (adjusted OR, 0.12; 95% CI, 0.04-0.37). For behavior, those who agreed they do not routinely start long-term medications because they cannot see patients in follow-up were less likely to be frequent prescribers (adjusted OR, 0.21; 95% CI, 0.07-0.58).

CONCLUSIONS

Emergency department physicians report low rates of ICS prescribing. Commonly cited barriers include unclear guidelines, believing that long-term medication prescribing is not within their role, and inability to see patients in follow-up. Addressing guideline discrepancies may improve preventive care delivery in the ED.

Parental education on asthma severity in the emergency department and primary care follow-up rates

Asthma is the most prevalent chronic condition affecting children and a common chief complaint in emergency departments (EDs). We aimed to improve parents' understanding of their child's asthma severity on accessing our pediatric ED for an acute asthma exacerbation. A retrospective chart review was conducted to determine outpatient follow-up rates from our ED in 2010-2011. In an attempt to educate parents at ED discharge about their child's asthma severity at presentation, we included a visual severity scale on their discharge instructions. Postdischarge telephone interviews were completed to determine postintervention follow-up rates. Asthma follow-up rates at 1 week improved from 20.8% to 50% after intervention. This difference was statistically significant after controlling for age and clinical asthma score with logistic regression (P < .0001). Offering predischarge education about a child's initial asthma severity is a simple intervention that significantly improved follow-up rates for children seen in the ED for asthma exacerbation.

A cost-effectiveness analysis of inhaled corticosteroid delivery for children with asthma in the emergency department

OBJECTIVE

To determine the clinical effectiveness and cost-effectiveness of 3 inhaled corticosteroid (ICS) delivery options for children with asthma treated in and discharged from the emergency department (ED).

STUDY DESIGN

We conducted cost-effectiveness analysis using a decision tree to compare 3 ED-based ICS delivery options: usual care (recommending outpatient follow-up), prescribe (uniformly prescribing ICS), and dispense (uniformly dispensing ICS). Accounting for expected follow-up rates, prescription filling, and medication compliance, we compared projected rates of ED relapse visits and hospitalizations within 1 month of ED visit across all 3 arms. Direct and indirect costs were compared.

RESULTS

The model predicts that the rate of return to ED per 100 patients within 1 month of the ED visit was 10.6 visits for the usual care arm, 9.4 visits for the prescription arm, and 8.4 visits for the medication-dispensing arm. Rates of hospitalization per 100 patients were 2.4, 2.2, and 1.9, respectively. Direct costs per 100 patients for each arm were $23,400, $20,800, and $19,100, respectively. Including indirect costs related to missed parental work, total costs per 100 patients were $27,100, $22,000, and $20,100, respectively. Total cost savings per 100 patients comparing the usual care arm with the medication dispensing arm was $7000.

CONCLUSIONS

This decision analysis model suggests that uniform prescribing or dispensing of ICS at the time of ED visit for asthma may lead to a decreased number of ED visits and hospital admissions within 1 month of the sentinel ED visit and provides a substantial cost-savings.

Racial and ethnic differences in the management of childhood asthma in the United States

OBJECTIVES

We examined racial and ethnic differences in the management of childhood asthma in the United States and the extent that care conformed to clinical best practices.

METHODS

Two years of pooled data from the National Health Interview Survey were analyzed using logistic regression. The sample included all children between ages 2 and 17 years who had asthma currently and had been diagnosed with asthma by a doctor or health professional (n = 1757; 465 African-American, 212 Mexican-American, 190 Puerto Rican and other Hispanic, 806 white, non-Hispanic, and 84 children of other and multiple races and ethnicities).

RESULTS

African-American children with asthma were significantly less likely than white, non-Hispanic children to have taken preventive asthma medication, but more likely to have had an asthma management plan. Mexican-American and Puerto Rican and other Hispanic children did not differ significantly from white, non-Hispanic children in either receiving preventive asthma medication or having an asthma management plan. Caregivers of African-American and Puerto Rican and other Hispanic children were more likely to report that they or their child had taken a course or class on how to manage their child's asthma. We did not find racial or ethnic differences in the extent children used quick-relief asthma medication or received advice about reducing asthma triggers in their home, school, or work environments.

CONCLUSIONS

This work highlights a need for more research on racial and ethnic differences in asthma management. Implications for public health responses and racial and ethnic disparities in asthma morbidity are discussed.

Low rates of controller medication initiation and outpatient follow-up after emergency department visits for asthma

OBJECTIVE

To determine what proportion of patients who are seen in an emergency department (ED) for asthma receive inhaled corticosteroids or attend follow-up appointments.

STUDY DESIGN

This was a retrospective cohort study of 2007-2009 South Carolina Medicaid data. Enrollees aged 2-18 years who had an ED visit for asthma were included. Patients admitted for asthma or with an inhaled corticosteroid claim in the 2 months before the month of the ED visit were excluded. Covariates were sex, race, age, rural residence, and asthma severity. Outcome measures were a prescription for an inhaled corticosteroid filled within the 2 months after the ED visit and attendance at a follow-up appointment within the 2 months after the ED visit.

RESULTS

A total of 3435 patients were included. Out of the study cohort, 57% were male, 76% were of a minority race/ethnicity, 69% lived in an urban areas, 18% had inhaled corticosteroid use, and 12% completed follow-up. Multivariate analyses demonstrated that patients with severe asthma were more likely to receive an inhaled corticosteroid (OR, 2.9; 95% CI, 2.3-3.7) and attend a follow-up appointment (OR, 2.0; 95% CI, 1.5-2.6). Patients aged 2-6 years and those aged >12 years were less likely to attend follow-up (OR, 0.71; 95% CI, 0.56-0.90 and OR, 0.62; 95% CI, 0.47-0.83, respectively) (all models P < .0001).

CONCLUSION

Children with asthma seen in the ED have low rates of inhaled corticosteroid use and outpatient follow-up. This indicates a need for further interventions to increase the use of inhaled corticosteroids in response to ED visits.

Younger asthmatics are less likely to receive inhaled corticosteroids and asthma education after admission for exacerbation

BACKGROUND

Recommended care prior to discharge from an asthma hospitalization includes prescribing controller medications, providing asthma education, and scheduling a follow-up appointment.

OBJECTIVE

To identify factors associated with receipt of recommended preventive care among children hospitalized for asthma.

METHODS

Retrospective chart review of patients 2-18 years with primary diagnosis of asthma admitted to MUSC Children's Hospital in 2005. Gender, race, age (2-6 yrs v. 7-18 yrs), primary payer, and season of admission were recorded. Outcome variables were: prescription for inhaled corticosteroids (ICS), asthma education, and scheduling a follow-up appointment.

RESULTS

Of the 146 subjects analyzed, 59% were male, 69% non-white, 64% 2-6 years old, 73% Medicaid/other, and 66% were admitted between Oct-March. 73% were prescribed ICS, 71% got asthma education, and 66% had a follow-up appointment scheduled. Bivariate analyses showed that 2-6 year olds were less likely to get ICS (65% v. 88% p < .01) and asthma education (64% v. 84% p < .05). Multivariable analyses demonstrated that younger children were less likely to get ICS (OR= 0.27 95% CI 0.10 - 0.70), younger children were less likely to get asthma education (OR 0.29 95% CI 0.11- 0.74), and commercial payer patients were less likely to get follow-up appointments scheduled (OR 0.39 95% CI 0.18 -0.87) (all models, p < .05).

CONCLUSIONS

Among children hospitalized for asthma at our institution, younger patients are significantly less likely to receive inhaled steroids and asthma education. Targeting younger asthmatics may be a way to efficiently and effectively improve delivery of recommended preventive care in the hospital.

Inhaled corticosteroids should be initiated before discharge from the emergency department in patients with persistent asthma

National and International Guidelines concur that inhaled corticosteroids (ICS) are the preferred long-term maintenance drug therapy for mild persistent asthma for all ages. For moderate and severe persistent asthma, ICS are essential to optimal management, often concurrent with other key therapies. Despite strong evidence and consensus guidelines, ICS are still underused. While some patients who are treated in the emergency department (ED) have intermittent asthma, most have persistent asthma and need ICS for optimum outcomes. Failure to initiate ICS at this critical juncture often results in subsequent lack of ICS therapy. Along with a short course of oral corticosteroids, ICS should be initiated before discharge from the ED in patients with persistent asthma. Although the NIH/NAEPP Expert Panel Report 3 suggests considering the prescription of ICS on discharge from the ED, The Global Initiative for Asthma (GINA) 2008 guidelines recommend initiation or continuation of ICS before patients are discharged from the ED. The initiation of ICS therapy by ED physicians is also encouraged in the emergency medicine literature over the past decade. Misdiagnosis of intermittent asthma is common; therefore, ICS therapy should be considered for ED patients with this diagnosis with reassessment in follow-up office visits. To help ensure adherence to ICS therapy, patient education regarding both airway inflammation (show airway models/colored pictures) and the strong evidence of efficacy is vital. Teaching ICS inhaler technique, environmental control, and giving a written action plan are essential. Lack of initiation of ICS with appropriate patient education before discharge from the ED in patients with persistent asthma is common but unfortunately associated with continued poor patient outcomes.

Make an M-PACT on asthma: rapid identification of persistent asthma symptoms in a pediatric emergency department

OBJECTIVE

To develop and validate a brief assessment instrument for persistent asthma symptoms in a pediatric emergency department (ED) population.

METHODS

Parents of children aged 1 to 18 years being discharged home after treatment for acute asthma in an urban children's hospital completed a 6-item screen for persistent symptoms that had been developed from national guidelines and previously validated. During a follow-up phone call 4 weeks after the ED visit, the instrument was repeated. An 8-item asthma-related quality-of-life (ARQOL) instrument was also administered at both times to assess construct validity. Item analysis assessed the performance of individual items and their combination versus the full instrument.

RESULTS

Four hundred thirty-three children were enrolled, and 361 patients (83%) had complete data. Sensitivity and predictive value were calculated for the full screen and combination of items in detecting persistent symptoms at baseline and follow-up. A 3-item version included symptoms with activity, symptoms at night, and need for rescue albuterol. This version was 96% sensitive (95% confidence interval, 92-99) for persistent symptoms compared with the 6-item screen, and 69% (95% confidence interval, 62-76) of the participants continued to report persistent symptoms 4 weeks after the visit. For both screens, subjects with persistent symptoms had significantly worse ARQOL score at baseline and follow-up.

CONCLUSIONS

A brief screen can identify persistent symptoms in pediatric ED patients with good sensitivity compared with a longer instrument. Most of these patients will continue to report persistent symptoms and reduced ARQOL score 1 month after the ED visit and may be candidates for additional interventions in the ED to improve long-term asthma care.

Beliefs and barriers to follow-up after an emergency department asthma visit: a randomized trial

BACKGROUND

Studies in urban emergency departments (EDs) have found poor quality of chronic asthma care and identified beliefs and barriers associated with low rates of follow-up with a primary care provider (PCP).

OBJECTIVES

To develop an ED-based intervention including asthma symptom screening, a video addressing beliefs and a mailed reminder; and measure the effect on PCP follow-up and asthma-related outcomes.

METHODS

This randomized, controlled trial enrolled children aged 1 to 18 years who were discharged after asthma treatment in an urban pediatric ED. Control subjects received instructions to follow-up with a PCP within 3 to 5 days. In addition, intervention subjects (1) received a letter to take to their PCP if they screened positive for persistent asthma symptoms, (2) viewed a video featuring families and providers discussing the importance of asthma control, and (3) received a mailed reminder to follow-up with a PCP. All subjects were contacted by telephone 1, 3, and 6 months after the ED visit, and follow-up was confirmed by PCP record review. Asthma-related quality of life (AQoL), symptoms, and beliefs about asthma care were assessed by using validated surveys.

RESULTS

A total of 433 subjects were randomly assigned, and baseline measures were similar between study groups. After the intervention and before ED discharge, intervention subjects were more likely to endorse beliefs about the benefits of follow-up than controls. However, rates of PCP follow-up during the month after the ED visit (44.5%) were similar to control subjects (43.8%) as were AQoL, medication use, and ED visits.

CONCLUSIONS

An ED-based intervention influenced beliefs but did not increase PCP follow-up or asthma-related outcomes.

Towards Excellence in Asthma Management: final report of an eight-year program aimed at reducing care gaps in asthma management in Quebec

BACKGROUND AND OBJECTIVES

Asthma care in Canada and around the world persistently falls short of optimal treatment. To optimize care, a systematic approach to identifying such shortfalls or 'care gaps', in which all stakeholders of the health care system (including patients) are involved, was proposed.

METHODS

Several projects of a multipartner, multidisciplinary disease management program, developed to optimize asthma care in Quebec, was conducted in a period of eight years. First, two population maps were produced to identify regional variations in asthma-related morbidity and to prioritize interventions for improving treatment. Second, current care was evaluated in a physician-patient cohort, confirming the many care gaps in asthma management. Third, two series of peer-reviewed outcome studies, targeting high-risk populations and specific asthma care gaps, were conducted. Finally, a process to integrate the best interventions into the health care system and an agenda for further research on optimal asthma management were proposed.

RESULTS

Key observations from these studies included the identification of specific patterns of noncompliance in using inhaled corticosteroids, the failure of increased access to spirometry in asthma education centres to increase the number of education referrals, the transient improvement in educational abilities of nurses involved with an asthma hotline telephone service, and the beneficial effects of practice tools aimed at facilitating the assessment of asthma control and treatment needs by general practitioners.

CONCLUSIONS

Disease management programs such as Towards Excellence in Asthma Management can provide valuable information on optimal strategies for improving treatment of asthma and other chronic diseases by identifying care gaps, improving guidelines implementation and optimizing care.
