Optimizing inhaled therapy requires viewing each inhaler - patient pairing as a specific delivery system rather than interchangeable components. Durable antistatic VHCs, appropriate interfaces, and regular technique assessment with targeted education should be the standard of care. Future efforts should prioritize device-specific guidance, scalable education strategies, and implementation research to close the persistent gap between evidence and real-world practice.
