Introduction: Malaysia has a high rate of smoking prevalence and the figure is increasing. Although there has been many local and regional studies on the prevalence and symptomatology of chronic obstructive pulmonary disease patients, data is lacking on the degree of compliance to national management guidelines in the treatment of chronic obstructive pulmonary disease., Methods: 86 patients who attended the respiratory outpatient clinic of the Hospital Universiti Kebangsaan Malaysia were enrolled into a prospective, observational study., Results: 88 percent of the patients were male and the majority was ethnically Chinese (65 percent). The majority of patients were in the moderate to very severe categories, with a mean FEV1 of 0.97 +/- 0.56 L/sec and predicted mean FEV1 percentage of 43.1 +/- 21.3 percent. 58 percent of the patients were on long-acting beta-agonist, 65 percent were on inhaled steroids, and only 16 percent were on scheduled pulmonary rehabilitation., Conclusion: The low uptake rate for long-acting beta-agonist and pulmonary rehabilitation could be attributed to several factors. Financial cost, the need for strict compliance to a structured rehabilitation regime, lack of significant social support and clear up-to-date guidelines are possible reasons.

Background: This study was proposed to develop a composite of outcome measures using forced expiratory volume percentage of predicted, exercise capacity and quality of life scores for assessment of chronic obstructive pulmonary disease (COPD) severity., Materials and Methods: Eighty-six patients with COPD were enrolled into a prospective, observational study at the respiratory outpatient clinic, National University Hospital Malaysia (Hospital Universiti Kebangsaan Malaysia--HUKM), Kuala Lumpur., Results: Our study found modest correlation between the forced expiratory volume in 1 s (FEV(1)), 6 min walk distance and the SGRQ scores with mean (SD) values of 0.97 (0.56) litres/s, 322 (87) m and 43.7 (23.6)%, respectively. K-Means cluster analysis identified four distinct clusters which reached statistical significance which was refined to develop a new cumulative staging system. The SAFE Index score correlated with the number of exacerbations in 2 years (r = 0.497, p<0.001)., Conclusion: We have developed the SGRQ, Air-Flow limitation and Exercise tolerance Index (SAFE Index) for the stratification of severity in COPD. This index incorporates the SGRQ score, the FEV(1) % predicted and the 6 min walk distance. The SAFE Index is moderately correlated with the number of disease exacerbations.
