The study was carried out to describe the situation and factors influence on practice capacity on STI among HCPs in Ba Vi district, Hanoi. The results indicated that STI practice of HCPs in Ba Vi district is at low level and influenced by several factors. On avereage, practice score is 4.4/24. Factors contribute good impact on practice levels include dealing with STI patients, participating STI/RTI trainings (regression coefficient 2.2 and 1.2
p 0.05). However, effective of training programs is still at low level. Conclusion and recommendations: At grassroot healthcare level, practise on STI is very poor among HCPs.
