Perceptions of asthma control in the United Kingdom: a cross-sectional study comparing patient and healthcare professionals' perceptions of asthma control with validated ACT scores.

Perceptions of asthma control often vary between patients and physicians. This cross-sectional survey provided UK-specific data on actual and perceived asthma control in patients (18-75 years) attending routine asthma reviews in primary, secondary and tertiary settings. Differences between healthcare professionals' (HCP) and patients' perceptions of asthma control were evaluated via an online questionnaire and compared to a control-the validated asthma control test (ACT)-which patients completed. Treated patients (at least a short acting ß-agonist) with a documented diagnosis of asthma were enroled and consented within a month of their last appointment. Patients were grouped according to the British Thoracic Society (BTS)/Scottish Intercollegiate Guidelines Network (SIGN) 2014 treatment guidelines (BTS/SIGN steps 1-5). A total of 260 patients were screened: 234 were eligible for enrolment: 33, 52, 50, 49 and 50 patients in steps 1-5, respectively. Seventy per cent (164) were women. The percentage of patients aged 45-64 years was 47.4%. HCPs classed 70% (164) as non-smokers. 84.2% of patients and 73.9% of HCPs perceived that asthma was controlled but ACT results suggest that asthma was only controlled in 54.7% of patients (ACT score ≥20). Patients in steps 4 and 5 had the highest levels of uncontrolled asthma. Correct agreement between ACT score with perceptions of controlled or uncontrolled asthma occurred in 67.9% of patients and 68.8% of HCPs; the poorest levels of agreement occurred in patients in steps 4 and 5. Uncontrolled asthma is common in UK patients. High proportions of patients and HCPs have incorrect perceptions of asthma control, especially in relation to patients with asthma in steps 4 and 5. ASTHMA: MISPERCEPTIONS OF CONTROL ABOUND AMONG UK PATIENTS AND DOCTORS: Asthma patients and their doctors often misperceive whether the disease is under control, according to a British study. Andrew Menzies-Gow from Royal Brompton Hospital in London and Gavin Chiu from Boehringer Ingelheim UK in Bracknell used an online questionnaire to assess perceptions of asthma control among 234 patients and their healthcare providers. All participants had at least intermittent asthma that required occasional treatment; many had more severe disease. The researchers found that 84% of patients and 74% of doctors thought the asthma was well controlled, but results of the Asthma Control Test indicated only 55% of patients objectively achieved disease control. Correct agreement between the validated test and more subjective perceptions occurred in only 68 % of patients and 69% of doctors. Addressing this mismatch could go a long way to improving asthma control among British patients.
