- Conditions
- Tobacco Use Cessation

- Other: Usual careOther: Chat bot
- Registration Number
- NCT03445507
- Lead Sponsor
- Gerencia de Atención Primaria, Madrid
- Brief Summary
This study aims to evaluate the effectiveness of an intervention to help people to quit smoking throughout an chat bot compared with usual assistance to increase long-term rates of nicotine abstinence in smoking outpatients with biochemical validation at 6 months.
Half of participants(control group) will receive usual care by their usual general practitioners and nurses, and the other half (intervention group) will use an evidence-based chat bot specifically designed to help people quit smoking.
- Detailed Description
An array of interventions have been shown to be both cost-effective and efficacious in helping patients quit smoking and so are included in usual care given by general practitioners and nurses. However, in the primary care setting, this sort of interventions are less common than they should be, due to many circunstances, and solutions must be found due to the huge dimensions of tobacco use challenge.
On the other hand,new kinds of information tecnology give a chance to intervene with less costs and more specific tools. Actually, there are a lot of mobile apps and other devices designed to help people to improve their health in many ways, but without scientific evidence of their effects.
This is a pragmatic, randomised, controled and multicentric clinical trial that tries to evaluate in general population the effectiveness of a chat bot that incorporates evidence based interventions and interacts by a text application instaled in patients mobile phone (intervention group).
Investigators have decided to compare with usual care delivered by the usual general practisioners and nurses of Spanish Public Health Centres, because this interventions have shown their effectiveness (control group).
Efficiency and impact on quality of life will also be compared on both groups.

- Primary Outcome Measures
Name Time Method Continuous tobacco abstinence at six months biochemically validated Six months Patient declares to have smoked less than five cigarettes in the last six months and have less than 10 parts per million (ppm) of carbon monoxide in exhaled air measured by a Pico+TM Smokerlyzer® cooximeter
- Secondary Outcome Measures
Name Time Method Continuous tobacco abstinence at six months referred by patient Six months Patient declares to have smoked less than five cigarettes in the last six months
Number of therapeutic contacts Six months Number of contacts (therapist-patient or bot-patient) during the therapeutic process
Time spent in therapy Six months Total amount of time spent (in minutes) during the therapeutic process
Descriptive improvement in patient´s quality of life Six months EuroQol 5D-5L questionary score descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Patient is asked to indicate health state by ticking the box next to the most appropriate statement in each dimension. This results in a 1-digit number that expresses the level selected for that dimension. Digits can be combined into a 5-digit number that describes the patient's health state.
Sujective improvement in patient´s quality of life Six months EuroQol 5D-5L questionary score visual analogue scale (EQ VAS).
EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. Can be used as a quantitative measure of health outcome that reflect the patient's own judgement.QALYs Six months Quality-adjusted life years
