First Step in Managing a Patient with Asthma

The first step in managing a patient with asthma is to assess asthma severity to determine the appropriate initial treatment, which includes classifying the patient's asthma as intermittent or persistent (mild, moderate, or severe) based on both impairment and risk domains. 1

Initial Assessment Components

The initial assessment should focus on characterizing the patient's asthma to guide appropriate therapy initiation:

1. Classify asthma severity using both domains:

   • Impairment domain: Frequency of symptoms, nighttime awakenings, use of rescue medications, activity limitation, and lung function
   • Risk domain: Frequency of exacerbations requiring oral corticosteroids, risk of progressive loss of lung function

2. Identify precipitating factors for symptoms:

   • Exposure to allergens (home, work, school)
   • Irritants and pollutants
   • Exercise triggers
   • Occupational sensitizers

3. Identify comorbid conditions that may worsen asthma:

   • Sinusitis and rhinitis
   • Gastroesophageal reflux disease (GERD)
   • Obstructive sleep apnea (OSA)
   • Obesity
   • Psychological factors (stress, depression)

4. Assess patient's knowledge and skills for self-management

Treatment Algorithm Based on Severity Classification

After assessing severity, treatment follows a stepwise approach:

Step 1: Intermittent Asthma

• Preferred treatment: Short-acting beta-agonist (SABA) as needed for symptoms 1
• No daily controller medication needed
• Consider environmental control measures

Step 2: Mild Persistent Asthma

• Preferred treatment: Low-dose inhaled corticosteroid (ICS) 1
• Alternative treatments: Cromolyn, leukotriene receptor antagonist, nedocromil, or theophylline

Step 3: Moderate Persistent Asthma

• Preferred treatment: Low-dose ICS plus long-acting beta-agonist (LABA) OR medium-dose ICS 1
• Alternative treatment: Low-dose ICS plus either leukotriene receptor antagonist, theophylline, or zileuton

Step 4-6: Severe Persistent Asthma

• Higher-dose ICS plus LABA with additional controllers as needed
• Consider biologics (omalizumab) for allergic asthma
• May require oral corticosteroids in step 6

Essential Components of Initial Management

1. Patient education on:

   • Difference between controller and rescue medications
   • Proper inhaler technique
   • Self-monitoring of symptoms and/or peak flow
   • Recognition of worsening asthma signs

2. Written asthma action plan developed in partnership with the patient that includes:

   • Daily management instructions
   • How to recognize and handle worsening asthma
   • When to seek emergency care

3. Environmental control measures to reduce exposure to allergens and irritants:

   • Identify specific sensitivities through testing if persistent asthma
   • Implement multi-faceted approaches to reduce exposures
   • Advise all patients to avoid tobacco smoke

4. Follow-up scheduling:

   • 2-6 week intervals for patients starting therapy
   • Adjust intervals based on level of control achieved

Common Pitfalls to Avoid

1. Underestimating severity: Each emergency consultation should be treated as potentially severe until proven otherwise 2

2. Delayed corticosteroid administration: Benefits may take 6-12 hours to appear, so early administration is crucial 2

3. Poor adherence assessment: A common reason for treatment failure is non-adherence to controller medications 3

4. Inadequate inhaler technique education: Proper technique is essential for medication effectiveness

5. Failure to address comorbidities: Uncontrolled comorbid conditions can limit asthma control

6. Inappropriate discharge from care settings: Ensure patients meet all criteria before discharge 2

By following this structured approach to initial asthma management, focusing first on severity assessment to guide treatment decisions, clinicians can establish effective control and reduce the risk of exacerbations, hospitalizations, and mortality.
