Experimental: Intensive smoking cessation intervention
The intervention includes 1) Individual motivational counseling in combination with 2) nicotine replacement therapy.
The intervention consists of five individual motivational counselling sessions, each lasting 20 to 40 minutes over a period of six weeks with a trained smoking cessation counsellor. The principles of motivational counselling are based on the trans theoretical model of change. The smoking cessation counsellor has also been trained in motivational counselling techniques specific to this intervention.
2. Nicotine replacement therapy The participants in the intervention group will be offered nicotine replacement therapy (NRT) free of charge and if accepted it will be tailored individually according to the Fagerström's Test for Nicotine Dependence.
The participants will note their tobacco and NRT consumption in a smoking diary.
Behavioral: Intensive smoking cessation intervention
The intervention includes 1) Individual motivational counseling (5 meetings within 6 weeks) in combination with 2) nicotine replacement therapy.
No Intervention: Control
The control group will receive the standard treatment and care in the rheumatology outpatient clinic. The participants will be encouraged to write a diary describing their tobacco use during the trial period. If participants in the control group express an interest in receiving smoking cessation counselling, they will be informed about municipal programs.
- Self-reported continuous smoking cessation validated by exhaled carbon-monoxide at 3 months follow-up [ Time Frame: 3 months post-intervention ]The participants' smoking status will be monitored by self-reported continuous smoking cessation validated by exhaled carbon monoxide (CO) in breath (CO-Check, NEOMED GmbH; Germany). Carbon monoxide values > 10 parts per million (ppm) indicate tobacco smoking
- EULAR clinical response (an improvement in DAS28 of >0.6) at 3 months follow-up [ Time Frame: 3 months post-intervention ]The recommended EULAR clinical response in relation to disease activity will be assessed using DAS28 at 3 months post-intervention. The DAS28 score consists of four elements; CRP, number of swollen joints, number of painful joints (maximum 28) and a Global General Health VAS score. The joint count and Global General Health are assessed by both the participant and a project nurse blinded to group allocation
- Self-reported smoking status at 6 and 12 months post-intervention [ Time Frame: 6 and 12 months post-intervention ]Smoking status will be monitored by self-reported continuous smoking cessation and biochemically validated by exhaled CO. Continuous smoking cessation will be measured by asking the patients who reports 7-day point prevalence (7 day time-line follow back) how many days they have not been smoking. Smoking status information is self-reported by the participant and documented in the smoking diary at 3 months post intervention (week 18). To be grouped as having "stopped smoking" both self-reported and biochemical analysis should indicate this.
- EULAR repsonse at 6 and 12 months post-intervention [ Time Frame: 6 and 12 months post-intervention ]Disease activity will be registered by DAS28, as described above in primary outcome.
- Disease activity measured by DAS28 at 3, 6 and 12 months post-intervention [ Time Frame: 3, 6 and 12 months post-intervention ]DAS28 as described above.
- Change in number of swollen and tender joints at 3, 6 and 12 months post-intervention [ Time Frame: 3, 6 an 12 months post-intervention ]Assessed by a person blinded to the intervention
- Physician and patient Global VAS [ Time Frame: 3, 6 and 12 months post-intervention ]Assessed by a person blinded to the intervention
- C-reactive protein (CRP) [ Time Frame: 3, 6 and 12 months post-intervention ]Measured using blood sample.
- Patient assessed disease activity by the FLARE Instrument [ Time Frame: 3, 6 and 12 months post-intervention ]Participants will be asked to answer the FLARE instrument (FI), which is a patient self-assessment questionnaire for detecting changes in disease activity among patients with RA. It is designed to detect both past and present disease activity. The questionnaire consists of 12 questions answered on a Likert scale (0 = completely agree, 10 = completely disagree). Higher scores indicate flare. A score > 2.5 indicates a flare.
- Blood pressure and pulse [ Time Frame: 3, 6 and 12 months post-intervention ]• Blood pressure (mmHg) and heart rate (beats/min) will be measured after 5 minutes of rest (supine position) (Mobil-O-Graph, IEM; Germany). If it exceeds 140/90 mmHg, two additional measurements will be performed and the mean of the last two will be registered.
- Arterial stiffness [ Time Frame: 3, 6 and 12 months post-intervention ]• Arterial stiffness will be measured by pulse wave velocity (PWV) (Mobil-O-Graph, IEM; Germany). High PWV is defined as > 9.9 m/s
- Serum lipids [ Time Frame: 3, 6 and 12 months post-intervention ]Serum lipids (TC, HDL-c, LDL-c and TG) will be measured in venous blood samples.
- HbA1c [ Time Frame: 3, 6 and 12 months post-intervention ]Will be measured using blood sample.
- Waist circumference [ Time Frame: 3, 6 and 12 months post-intervention ]• Waist circumference will be evaluated by a tape measure in centimetres (cm) while the patient is standing. For women with a waist circumference >80 cm there is an increased risk of CVD while the risk is further increased for waist circumference >88 cm. For men the measures are defined as >94 cm and >102 cm, for increased, and further increased, risk of CVD, respectively.
- Body weight [ Time Frame: 3, 6 and 12 months post-intervention ]• Body weight will be measured to the nearest 0.1 kg (with ordinary clothes, but without shoes) (OBH Nordica, Slim Light, 150 kg, Taastrup Denmark).
- Lung function [ Time Frame: 3, 6 and 12 months post-intervention ]FEV1 will be measured by spirometer (EasyOneTM, Model 2001 diagnostic Spirometer, Model 2010 Cradle, NDD Medizintechnik AG; Switzerland).
- Physical function [ Time Frame: 3, 6 and 12 months post-intervention ]HAQ is a standardized questionnaire for assessing disability and physical function in patients with RA. The instrument contains 20 items with four possible answers in eight categories; dressing, rising from a seat, eating, walking, personal hygiene, stretching for an object, grabbing an object and everyday activities. The questionnaire also includes VAS scales for pain, fatigue and general health. In DANBIO five additional questions have been added. They also have four possible answers and relate to physical function, sleep, anxiety and depression. In this study we will use the 25 questions as used in DANBIO.
- Health-related quality of life [ Time Frame: 3, 6 and 12 months post-intervention ]
HR-QoL is measured using the following two questionnaires:
- SF-36 is a generic instrument measuring HR-QoL by 36 items on eight scales. The scales are; physical function, physical activity, limitations, pain, general health, vitality, social function, emotional activity limitations and mental health; they are summarized in two summary scales; 1) the physical component scale (PCS) and 2) the mental component scale (MCS).
- The questionnaire contains five items (movement, personal care, usual activities, pain and anxiety/depression) each with five possible ratings.
- Pain Pain [ Time Frame: 3, 6 and 12 months post-intervention ]Pain related to RA is self-reported by participants using the VAS. Participants rate their subjectively experienced level of pain from 0-10. Zero represents "no pain" and 10 represent the "worst imaginable pain". The scale is included in HAQ.
- Fatigue [ Time Frame: 3, 6 and 12 months post-intervention ]The BRAF-NRS assesses fatigue in patients with RA. It includes three questions concerning fatigue (level, effect and coping) over the previous seven days. Participants rate fatigue on a scale from 0-10 . Zero represent "no fatigue" and 10 represent the "worst fatigue".
