Introduction:
The Physical Therapy Network for Smoke-free Thai Society has a role in supporting physical therapists to develop smoking-cessation projects in 12 regional health services in Thailand. These projects provided smoking-cessation services in population level approach to allow easy access. During 2016-2018, 36 projects had been supported; however, the lesson learnt from implementing these projects had not yet been formulated.

Objectives:
This qualitative study aimed to draw lesson learnt from the smoking-cessation project managers’ experiences.

Methods:
Five project managers were asked to answer two open ended questions including “What were the successful factors?”, and “what were the barriers?”. Data was analyzed by content analysis. The finding was validated by the 12 regional network coordinators.

Results:
The results found that the successful factors were as follows: 1) Physical therapists working as a regional team to develop smoking cessation service systems together and to consistently follow up the measures. 2) Strengthening and empowering the community network such as village health volunteers and smokers’ family members. 3) Taking health crisis such as cerebrovascular disease and chronic obstructive pulmonary disease to persuade smokers to quit smoking. 4) Utilizing Line group for efficient communication within the network. The main barriers were lack of time due to high workload, and lack of smoker database that can be used for referral and follow-up by multi-disciplinary team.

Conclusion(s):
Smoking cessation projects developed by regional physical therapy team are more efficient than those developed by individual. The smoker database systems should be developed to serve the utilization of multi-disciplinary team.
