TEXAS CHILDREN'S HOSPITAL DATE 7/2008

EVIDENCE-BASED CLINICAL OUTCOMES DECISION SUPPORT

ASTHMA/RECURRENT WHEEZING MANAGEMENT CLINICAL GUIDELINE

Guideline Eligibility Criteria: Patients ≥ 1 year with adiagnosis of asthma/recurrent wheezing in whom foreignbody or vocal cord dysfunction have been ruled out.

Guideline Exclusion Criteria: Bronchiolitis, cystic fibrosis,bronchopulmonary dysplasia, bacterial pneumonia,neurological disorders, immuno-deficiency diseases, trachpatients, and cardiac patients (unless ordered).

Definition:(1-3)

Asthma is the most common chronicdisorder in childhood (10-12%). It is an inflammatorydisorder of the airways in which cells and cellular elementsplay a role. In susceptible individuals, inflammation causesrecurrent episodes of coughing (particularly at night or earlymorning), wheezing, breathlessness, and chest tightness.Asthma breathing problems or exacerbations are “episodic”,however, the underlying inflammation is continuous.Environmental factors play a critical role in asthmarecognition and management. Asthma exacerbations areassociated with widespread but variable airflow obstructionand are often reversible with or without treatment.

Pathophysiology:(1, 3-5)

Asthma is a complex, interactiveprocess that depends on the interaction of: Bronchoconstriction Airway hyper responsiveness Airway edema

Asthma Predictors:(1, 9-12)

Family history of asthma, eczema, and/or smoking Patient history of allergic rhinitis, sinusitis, nasal polyps,

eczema, or BPD Recurrent cough, bronchitis, and bronchiolitis

Diagnosis:(1-5)

The initial diagnosis of asthma in childrenis often difficult and requires that other diagnoses beexcluded. An in depth clinical history combined with athorough physical examination are necessary to make thisdetermination.

History: Assessment of(1, 3-5)

Cough, wheeze, shortness of breath, and/or chesttightening that occurs in an “episodic” fashion. Thesesymptoms may occur or worsen with:

- Exercise- Changes in the weather- Night hours- Viral infection(s)- Inhalant trigger exposure (smoke, fur, dust mites,

mold, pollen, etc.)- Irritant trigger exposure (airborne chemicals

(aerosols), smoke, etc.)- Strong emotional expressions (laughing, crying)- Menstrual cycles

Tests to exclude other diagnoses when H&P is equivocal: Chest x-ray Bronchoprovocation test Allergen testing (eosinophilia, total IgE, rarely aspergillosis)

Physical Examination: Assess for(1, 3-5)

Severity of respiratory symptoms using the ClinicalRespiratory Score (CRS, p.2)

Rhinitis, increased nasal secretions, mucosalswelling, or nasal polyps

Airflow obstruction or airway hyper responsiveness arepresent and are at least partially reversible

e.g. spirometry shows Forced Expiratory Volumein 1 second of 12% from baseline or 10% ofpredicted after the patient inhales a short-actingbronchodilator.

Note: Office based physicians who manage asthmapatients should have access to spirometry that meetsATS standard

(1,6)

Diagnostic Tools to Assess Severity (Tables 1 & 3)(1,6)

1. Spirometry - FEV1 in children ≥ 5 yearsAirway hyper responsiveness test using Methacholine

Patients at risk of asthma-related death should beadvised to seek medical care early during anexacerbation (Table 3, p 4).

Factors that place patients at risk for asthma-relateddeath include:

(1, 4)

Co-morbid conditions such as heart or lung disease Previous severe exacerbation (e.g. intubation or ICU

admission) ≥ 2 hospitalizations or > 3 EC visits in the past year Use of > 1 canister of Short Acting Beta Agonist (SABA)

per month Difficulty perceiving airway obstruction or the severity of

worsening asthma (parent &/or child) Low socioeconomic status or inner-city residence Illicit drug use Major psychosocial problems or psychiatric disease

Life-threatening asthma is a constellation of symptoms thatcan occur in any patient with asthma and includes: Marked chest tightness Wheezing, severe shortness of breath Retractions Cyanosis Inability to speak or speak in sentences due to dyspnea Hunched posture Altered mental status (agitation, anxiety, lethargy)

Co-morbid Conditions:(1, 7-8)

Gastroesophogeal refluxdisease (GERD), obstructive sleep apnea (OSA), obesity,rhinitis, and sinusitis

Goals of Therapy: To reduce the frequency and severityof asthma exacerbations and reduce long term sequelae bymaintaining asthma control with the least amount oftherapeutic interventions/medications possible. Intensiveeducation and monitoring are required in caring for allchildren with asthma.

(Add score from all rows to calculate total CRS score)

Exacerbation Management (see RespiratoryAssessment and Management Protocol (RAMP, p 6):In-Home and/or Office1. Assess severity to initiate therapy (1st time episode

(CRS Score above & Table 1, p 3)2. Classify severity of exacerbations (Table 3, p 4)3. Identify triggers and manage control measures4. Initiate use of inhaled short acting beta agonist

(SABA)5. Begin oral systemic corticosteroid6. Offer supplemental oxygen if necessary and available7. Identify and manage aggravating co-morbid conditions8. Provide ongoing education (Table 4, p 4)9. Consider EC admission if symptoms persist, are of

sufficient severity, or patient has risk factors forasthma related death (see sections below)

Emergency Center1. Follow above steps, and if severity warrants2. Place on continuous SABA3. Double up dose of inhaled corticosteroids4. Initiate ipratropium bromide5. Change systemic corticosteroids to IV6. If condition unchanged or worsening consider initiation

of adjunctive therapies including: IV magnesiumsulfate (evidence supports), IV terbutaline (evidenceinconclusive), heliox (evidence inconclusive), andnon-invasive positive pressure ventilation (NPPV -evidence inconclusive). If symptoms do not improveconsider PICU admission

7. If symptoms are unchanged or improving slightly butcontinued close monitoring is still required considerinpatient admission

8. If symptoms have improved or ceased initiateASTHMA ACTION PLAN and discharge home to f/uwith PCP.

PICU1. Continue above and consider adjunctive therapies yet

to be initiated (see RAMP p 6)2. Consider intubation for mechanical ventilation

Inpatient Care1. Continue therapies initiated and wean as appropriate

according to RAMP (p 6)2. Evaluate patient/caregiver knowledge and skills and

provide re-enforcement or required education (Table4, p 4)

3. Initiate Asthma Action Plan to prevent chronic anddisabling symptoms

Office Follow-up and Long-term Management1. Assess control (frequency of SABA use for symptom

management and PEF) to monitor and adjust therapy(Table 2, p 3)

Note: Spirometry can demonstrate obstruction andassess reversibility in patients ≥ 5 years

2. Consider daily peak-flow monitoring in patients withmoderate or severe persistent asthma; a history ofsevere exacerbations; or who are unable to perceiveairway obstruction or worsening asthma.

3. Classify severity of exacerbations (Table 3, p 4)4. Initiate Asthma Action Plan (see p 7 & 8)

Pharmacotherapies that should be included are:Long Term Control Medications: Inhaled corticosteroids (ICS) Long acting ß agonists for mod persistent asthma

(LABA) Leukotriene receptor agonists Anti-immunoglobulin E for severe persistent allergic

asthma in children ≥ 12 yearsQuick Relief or Exacerbation Medications: Short acting ß agonists (SABA) Oral systemic corticosteroids (OCS)

(Refer to TCH Formulary for prescribing info)(22)

Outcome Measures:(23-25)

1. Increased use of asthma order sets2. All pts have Action Plans with copy on chart3. Appropriate treatment with anti-inflammatory medication4. Reduction in Average Length of Stay (LOS)5. Arrival to delivery timing of steroid administration6. Number of IDS pts with an Action Plan at admission7. Increased % of pts receiving influenza immunization8. Neb Mask vs MDI exclusions appropriately applied

Keys Components of Patient and Family Asthma Education

Basic Facts: The contrast between

airways of a person whohas and a person whodoes not have asthma

The role of inflammation.

What happens to theairways during an asthmaattack.

Role of Medications: Long-term control medications:

o Prevent symptoms, often byreducing inflammation. Mustbe taken daily.

Quick-relief medications:o Short acting beta agonists

relax airway muscles toprovide prompt relief ofsymptoms.

Note: Use of short acting ß agonistquick relief medications >2 days aweek to relieve asthma symptomssuggests the need to re-assessasthma control and considerescalation of therapy.

Patient Skill Set: Self-monitoring:

o Self-assessment of level of asthma control.o Monitoring symptoms and, if prescribed, Peak

Expiratory Flow Measures.o Recognizing symptom patterns & early signs

and symptoms of worsening asthma.o Use of a written asthma action plan to know

when and how to:- Take daily actions to control asthma.- Adjust medication(s) early in response to

signs of worsening asthma- Seek medical care as directed- Value of compliance and periodic

monitoring to adjust therapy Taking medications correctly Inhaler technique (demonstration/return demonstration) Use of devices as prescribed (valved holding chamber or

spacer, nebulizer). Identifying and avoiding triggers that worsen the patient’s

asthma (allergens, irritants, tobacco smoke)

Guideline Preparation

This guideline was prepared by the Evidence-Based (EB)Clinical Decision Support Team in collaboration with contentexperts at Texas Children’s Hospital and the Texas Children’sPediatric Associates. Development of this guideline supports theTCH Quality and Patient Safety Program initiative to promoteclinical guidelines and outcomes that build a culture of qualityand safety

Development Process

This guideline was developed using the process outlined in theEB Clinical Decision Support Manual (2007). The reviewsummary documents the following steps:1. Review Preparation

-PICO questions established-Evidence search terms confirmed with content experts

2. Review of Existing Internal and External Guidelines- One internal bronchiolitis guideline found (Critical Care-

Dr. McPherson)- One published guideline from the AAP/AHRQ and two

from children’s hospitals were used

3. Search for Relevant Evidence-Searched: Medline, EmBase, Cochrane, AHRQ,

CINAHL, Trip, Best BETS, AAP, PedsCCM, U of Mich,Google Scholar

4. Critically Analyze the Evidence5. Summarize the Evidence by preparing the guideline, order

sets and interdisciplinary plan of care- Materials used in the development of the guidelines,

review summaries and content expert team meetingminutes are maintained in a bronchiolitis EB reviewmanual within the Center for Quality.

Evaluating the Quality of the Evidence

The Critical Appraisal Skills Program (CASP) criteria wereused to evaluate the quality of articles reviewed. Application ofthe CASP criteria are completed by rating each reviewed studyor review as:

Strong study/systematic review - well designed, wellconducted, adequate sample size, reliable measures, validresults, appropriate analysis, and clinically applicable/relevant.

Study/systematic review with minor limitations - specificallylacking in one of the above criteriaStudy/systematic review with major limitations - specificallylacking in several of the above criteria.

Published clinical guidelines evaluated for this review using theAGREE criteria. The summary of these guidelines are found atthe end of this document. AGREE criteria uses a 1-4 point likertscale to evaluate 23 questions evaluating: Guideline Scope andPurpose, Stakeholder Involvement, Rigor of Development,Clarity and Presentation, Applicability, and EditorialIndependence. The higher the score the more comprehensivethe guideline.

This guideline specifically summarizes the evidence in supportof or against specific interventions and identifies whereevidence is lacking. The following categories describe howresearch findings provide support for treatment interventions.

“Evidence that supports” the guideline (p.2 & 3) providesevidence from more than one well-done randomized controlledtrial (RCT) (based on CASP criteria) that the benefits of theintervention exceed harm.“Evidence against” (p.2 & 3) provides clear evidence from

more than one well-done RCT (based on CASP criteria) that theintervention is likely to be ineffective or that it is harmful.“Evidence lacking” (p.2 & 3) indicates there is currentlyinsufficient data or inadequate data to recommend for or againstspecific intervention.

RecommendationsRecommendations for the guidelines were developed by aconsensus process directed by the existing evidence, contentexperts and patient and family preference when possible. TheContent Expert Team and EB Clinical Decision Support Teamremain aware of the controversies in the management ofbronchiolitis in young patients. When evidence is lacking, optionsin care are provided in the guideline and the order sets thataccompany the guideline.

Approval ProcessGuidelines are reviewed and approved by the Content ExpertTeam, EB Clinical Decision Support Team, EB ExecutiveSteering Team, Pharmacy and Therapeutics Committee andother appropriate hospital committees as deemed appropriate forthe guideline’s intended use. Guidelines are reviewed andupdated as necessary every 2 years within the EB ClinicalDecision Support Team at Texas Children’s Hospital. ContentExpert Teams will be involved with every review and update.

DisclaimerGuideline recommendations are made from the best evidence,expert opinions and consideration for the patients and familiescared for within TCH/TCPA. The guideline is NOT intended toimpose standards of care preventing selective variation inpractice that are necessary to meet the unique needs ofindividual patients. The physician must consider each patient’scircumstance to make the ultimate judgment regarding best care.
