Asthma Control Test Scores for Severe Asthma in 2020

Asthma control can be formally assessed by using validated instruments, including the Asthma Control Test™ (ACT). The ACT includes 5 questions that assess daytime symptoms, nighttime symptoms, reliance on as-needed “rescue” medication, the effect of asthma on everyday functioning, and patient assessment of control, with each of these 5 responses scored on a 1 to 5 scale. Higher scores reflect improved asthma control, a major objective of asthma management.

The ACT has been routinely used at Cleveland Clinic’s Asthma Center for more than a decade. All asthma patients are asked to complete the ACT when seen at initial and follow-up visits.

The 2020 data are reported in the context of a quality measure. The American Academy of Allergy, Asthma, and Immunology Qualified Clinical Data Registry (QCDR),¹⁻² which has been approved by Centers for Medicare and Medicaid Services, qualifies as a reporting tool for the Merit-based Incentive Payment System (MIPS).² Poor asthma control is measured by the ACT and indicated by an ACT score < 20, and an increase of 3 has been shown to be the minimal important difference for the ACT.³

With the unprecedented events of the coronavirus pandemic, a larger scale evaluation was limited due to ACT availability during this time, as in-person visits were suspended and most management was remote via phone calls or virtual visits. However data available was promising, demonstrating that asthma control in the most severe asthma patients improved and did not worsen.

Proportion of Severe Asthma Patients With Well Controlled Asthma Improved Between 2019 and 2020 (N = 258)

2020

ACT = Asthma Control Test

The chart displays a cohort of 258 patients with severe asthma and ACT data available who were cared for in the Asthma Center. Analysis demonstrates that the proportion of patients with controlled asthma seen in 2019 and subsequently in 2020 improved during that time interval.

These outcomes data demonstrate that, with comprehensive evaluation and multidisciplinary management (and often multimodal management in-person/virtually/telephonically) of 258 patients with ACT scores presenting to the Asthma Center, improved asthma control is possible even in the most severe cases. Rigorous monitoring and adjustments of therapies are needed as patients improve or require alternative advanced therapies available.⁴
