## Asthma Guideline Modernization
This presentation proposes three major revisions to Canadian primary care asthma guidelines based on recent evidence (2021-2026).

## Change #1: Universal Anti-Inflammatory Reliever Strategy
* **Proposal:** Eliminate SABA-only strategies. Prioritize ICS-Formoterol (MART) as the sole reliever for all severities.
* **Evidence:** As-needed ICS-formoterol reduces exacerbation risk by ~64% compared to SABA-only in mild cases.

## Change #2: Strict OCS Stewardship Protocols
* **Proposal:** Define >1 course of Oral Corticosteroids (OCS) per year as a mandatory trigger for specialist referral.
* **Rationale:** Frequent OCS use (>4g lifetime cumulative) is linked to diabetes, osteoporosis, and cataracts.

## Change #3: Mandated Structured Education
* **Proposal:** Elevate 'Inhaler Technique' and 'Written Asthma Action Plans' (WAAP) to mandatory quality metrics for reimbursement.
* **Data:** Approximately 70-80% of patients use inhalers incorrectly.

## Clinical & Health Systems Impact
* **Primary Care:** Shifting to ICS-Formoterol addresses the 'paradox of mild asthma' where infrequent users still face severe risks.
* **Systems:** Enforcing OCS stewardship reduces chronic disease burden and emergency department visits caused by SABA reliance.

## High Risk Indications for Referral
Specialist referral is recommended for:
* Poor control: >2 daytime symptoms per week despite ICS.
* SABA overuse: >2 canisters per year.
* History: Prior ICU admission or intubation.
* OCS Use: Any maintenance OCS or >1 burst per year.
