Asthma Control Test Scores for Severe Asthma
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 2021 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 were promising, demonstrating that asthma control in the most severe asthma patients improved.
