Introduction:
Influence of Chronic Obstructive Pulmonary Disease (COPD) has a global economic burden of Noncommunicable Diseases. COPD is increasingly becoming a cause of death in Thailand and trending to be a significant cause of death worldwide. In HRH MSMC hospital indicates that COPD is becoming more common amongst patient in significant scale.

Objectives:
COPD clinic is set up in HRH MSMC with contribution from pulmonologists, nurses, pharmacists, physical therapists, nutritionists, and tobacco control team to provide treatment, supervise medication, rehabilitation and counseling. This research aims to study the successful prototype of COPD clinic.

Methods:
A retrospective study collects data of patients in COPD clinic from January 2016 to December 2017. The outcome is compared between before and after enrollment in the COPD clinic.

Results:
Based on 80 patients data, 75 males, mean age is 72 year-old and the median of BMI is 21.72 (18.59-23.65). The median number of pack-year is 30 pack-year (20-37). The median duration of smoking cessation before enrollment is 7 years (3.25-12.0). The patients are composed of GOLD spirometry stage1 43.75%, stage2 37.5%, stage3 14.5%, and stage4 4.1%. We found that 50% of COPD clinic patients were successful in smoking cessation and 60% continued to stop smoking for at least 1 year (5 out of 10 active smokers that attend COPD clinic stopped smoking and 6 patients continued to stop smoking for at least 1 year). The median of COPD Assessment Test (CAT score) before enrollment is 8 (1.5-11.0) which improve to score 5 (2-10.5) and 4 (1-9) at 6 and 12 months after enrollment. And the 6-minute-walk distance (6MWD) test increased from the median of 276 m. (144-318) before enrollment to 282 m. (168-327) and 288 m. (180-324) at 6 and 12 months after enrollment.

Conclusion(s):
The successful of COPD clinic compound with tobacco control program could be a holistic care model.
