The aim of this study was to describe the level and perception of control in severe asthma in Trinidad after the
introduction of revised guidelines for asthma management. Adult asthmatics (N ¼ 329) at Trinidad’s chest
clinics were cross-sectionally examined for guideline-defined disease control. Patients’ mean (SD) age was
54.36 (14.9) years, with body mass index ¼ 28.54 (7.4) kg/meter2
, and females were proportionally more
(246, 74.74%). Measured (45.29%) and perceived (18.96%) uncontrolled disease were poorly concordant
(k statistic ¼ 0.197). Co-morbidity (2 conditions) correlated with uncontrolled disease in 55.80% of
patients (Spearman correlation p ¼ 0.03). Absolute peak expiratory flow was higher (p < 0.001) in
controlled and/or partially controlled disease than in uncontrolled asthma. Routine work limitation, nighttime
disturbances, work absenteeism, exacerbations, rescue inhalation and perceived control correlated
with uncontrolled asthma (p < 0.001). Few patients self-monitored lung function (9.73%) or kept an
asthma diary (6.69%), but 65.1% believed they had to live with their symptoms. The asthma burden was
at least one hospitalization (53.80%) and emergency department visit (66.36%) in the past year, cough
(74.49%), dyspnoea (84.50%), wheezing (80.55%) and chest tightness (66.87%). After the revised
guidelines, uncontrolled asthma and related morbidity remain suboptimal, with disagreeing actual and
perceived control. Efforts to transform guidelines into patient care with realistic interpretation of control
are recommended.
