The study was carried out from January to May 2013. Among 6600 subjects (age >40), 404 (6.1%) were defined as COPD. The co-morbidities, COPD related symptoms, health care resource utilization, and symptoms associated with obstructive sleep apnea (OSA) were collected and analyzed.ResultsComparing the effectiveness for evaluating co-morbidities, symptoms associated with COPD and OSA, there were significant differences in favor of CAT as compared to mMRC (P=0.021, P<0.001, P<0.001, respectively). When comparing health care resource utilization; CAT and mMRC have equal effectiveness in evaluating patients with regular medical follow-up (P<0.001, P<0.001), there were significant differences in favor of mMRC regarding emergency room visit and hospitalization (P=0.047, P<0.001). However, CAT has better effevtiveness in evaluating patients with ICU admission (P=0.005). In comparison with clinical symptom evaluation, CAT (divided into 2 groups; 0-9 and 10-40) and mMRC (divided into 2 groups; 0-1 and 2-5) did not show association in categorical variables (P=0.150). There was a concordance for categorical variables in only 33% of subjects (low CAT/mMRC or high CAT/ mMRC).ConclusionsThe CAT appears to be better than mMRC in profiling clinical symptoms, co-morbidities and medical resource utilization for ICU admission in COPD patients.
