Summary of the 2023 GINA Guidelines

Assessment

• A brief history and physical exam should be done concurrently with prompt treatment initiation. Important elements include timing, severity, risk factors for poor outcomes, current medications and response.
• Assess for signs of exacerbation severity, complications, and alternative causes of acute breathlessness.
• Objective measures like lung function and oxygen saturation should be obtained if possible before starting treatment. These help assess severity and monitor response.

Treatment

• Give oxygen to target saturation 93-95% in adults or 94-98% in children 6-11 years. Avoid excessive oxygen in adults.
• Give inhaled SABA as first line bronchodilator. Ipratropium bromide provides added benefit. Consider high dose ICS-formoterol as an alternative bronchodilator.
• Give systemic corticosteroids to all but mildest exacerbations. Use for 5-7 days in adults, 3-5 days in children. Oral and IV routes are equally effective.
• Add inhaled corticosteroids within the first hour if not on maintenance treatment. On discharge, prescribe maintenance ICS-containing treatment to reduce future risk.
• Other treatments like magnesium sulfate, leukotriene antagonists, aminophylline/theophylline, and antibiotics have little role unless specific indications. Avoid sedatives.
• Reassess after 1 hour of treatment. Patients with severe exacerbations not responding to treatment need ICU referral.

Hospitalization vs Discharge

• Factors favoring hospitalization include poor lung function after 1st hour of treatment, past history of severe exacerbations or intubations, and social factors impacting follow up.
• Discharge may be considered with post-treatment lung function 40-60% predicted and close follow up.
• Discharge is favored if post-treatment lung function is >60% predicted and risk factors/follow up are acceptable.

Discharge Planning

• Arrange early follow up visit. Provide oral corticosteroids, ICS-containing medications, and written asthma action plan.
• Review modifiable risk factors, inhaler technique, adherence, and patient responses during the exacerbation.
• For adults/adolescents, prescribe ICS-formoterol as the reliever to reduce future exacerbation risk.
