Groups2
Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention | The intervention group will receive nicotine replacement therapy (NRT) sampling and medication counseling. The nurse will help the subject to decide which NRT product (patch or gum) he/she can use and advise how to use the NRT based on his/her smoking habit and amount of cigarette consumption. In addition, the nurse will deliver medication counselling which addresses five main components: (1) the benefits for using NRT in quitting, (2) withdrawal symptoms due to smoking cessation, (3) side effects of NRT, (4) instructions for using NRT, and (5) making appointments for TWGHs SC clinics. Afterwards, the participant will receive 1-week free NRT, an education card about NRT and a one-page leaflet provided by the SC clinics.~Nicotine replacement therapy (NRT) sampling: 1-week free NRT samples (patch or gum)~Medication counseling: Medication counseling | 0 | 482 | EG000 |
| Group 2 | Control | The control group subjects will receive medication counseling. They will be advised to obtain free NRT by enrolling in the smoking cessation services, but will not be given the sampling. The same one-page leaflet will be provided by the SC clinics.~Medication counseling: Medication counseling | 0 | 352 | EG001 |
