Introduction Severe asthma is a debilitating, life-threatening disease associated with substantial global morbidity, mortality, and health care resource utilization. Patients may not receive guideline-directed medical care for severe asthma. Moreover, viable precision-based assessment tools and newer preventive therapies that can reduce the frequency of exacerbations and associated functional impact are underused. As a result, high rates of poorly controlled severe asthma persist, and patient health-related quality of life suffers. Methods In 2019, the Improve Access to Better Care Task Force of the PRECISION Steering Committee set out to develop a global template on quality standards for severe asthma care to support improved access to and delivery of quality care. This Quality Standard is grounded in the vast body of published evidence available for severe asthma care, published clinical guidelines (i.e., from the Global Initiative for Asthma in 2019 and the European Respiratory Society/American Thoracic Society in 2014), and the 2018 PRECISION-supportedCharter to Improve Patient Care in Severe Asthma. Results The Quality Standard developed emphasizes four key elements aimed at optimizing clinical care and outcomes in severe asthma: (1) organization of services, (2) timely identification and referral for suspected severe asthma, (3) specialized assessment and management of severe asthma to optimize outcomes, and (4) patient-centric care and shared decision-making that is reflective of the patient's expectations, priorities, and values. Four key Quality Statements are provided, along with quality metrics and strategies for local adaptation to optimize implementation. Conclusion This Global Quality Standard is intended to mobilize policymakers, health care providers, and patient advocacy groups to build consensus on the definition and expectations of quality care in severe asthma, to promote patient-centric care, to identify gaps in care and areas for improvement, and systematically implement improvement measures and outcomes and to reduce the burden of illness for patients with severe asthma. Plain Language Summary Although only 10% of patients with asthma have severe disease, these patients use up to half of all health care resources used to treat asthma. For the patient, severe asthma is associated with substantial morbidity, increased risk of death, and poor quality of life. Effective treatments for severe asthma are available, yet access to these treatments varies for many patients around the globe, and they are not always used effectively when available. A task force of leading global asthma experts was recently assembled to develop global standards to support improved access and delivery of quality care for patients with severe asthma. The task force identified four key elements to optimize management and outcomes: (1) coordination of services, (2) timely detection and referral of patients with severe asthma, (3) use of guideline-recommended assessments and therapies, and (4) integration of patient expectations and values when making treatment decisions. This Quality Standard details each of these elements by providing supporting rationale, ways to measure improvements in each area, and strategies to implement these elements at local clinics around the world. Ultimately, this Quality Standard is intended to help policymakers, health care providers, patient advocacy groups, and other key stakeholders build consensus on the requirements for quality care in severe asthma to improve patient care while also reducing the overall global burden of severe asthma.
