Our overall goal is to advance science related to using the Internet in health services delivery, and specifically smoking cessation by targeting dental hygienists. Our proposed intervention is the first Internet-delivered intervention to target the dental microsystem for smoking cessation-providing access to hygienists and patients.

Condition Intervention Phase
Smoking Cessation
Other: Electronic Referral
Early Phase 1

Study Type: Interventional

Further study details as provided by Dental Practice-Based Research Network:

Primary Outcome Measures:
  • Number of smokers referred to tobacco cessation website [ Time Frame: 12 months ]
    We will asses the number of patient referrals that the dental hygienists make to the tobacco cessation website.

Secondary Outcome Measures:
  • Proportion of smokers who go to the tobacco cessation website [ Time Frame: 12 months ]
    We will assess the proportion of smokers who were referred to the tobacco cessation website to the number of patients who registered on the website.

  • Point prevalence smoking cessation [ Time Frame: 6 months ]
    Tobacco cessation behaviors will be assessed by follow-up email and/or telephone interviews at six months from website enrollment.

Enrollment: 80
Study Start Date: April 2010
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Electronic Referrals
Dental practices randomized to the experimental group will have options on how to refer patients to the tobacco cessation website.
Other: Electronic Referral
Dental practices in this arm will be able to have option of making electronic patient referrals to the Decide2Quit website.
No Intervention: Routine Referral
Dental practices in this arm will refer patients to the Decide2Quit website by using an information prescription.

Detailed Description:

This study is designed to allow dental hygienists and dentists to provide additional tobacco cessation counseling with little additional marginal effort. This would be done using an Internet-based referral to external resources. This system, termed "ReferASmoker", will allow hygienists and dentists to refer patients to a patient education, self-management website, "Decide2Quit" and accompanying Quitline, while the patient is still in the dental office. We anticipate that hygienists will be the primary drivers of this intervention. Our intervention has several innovations designed to support the dental practice in their tobacco cessation activities and maximize patient cessation rates. We will randomize 80 community-based primary dental practices into a clinical trial.

Aim 1. To test hypothesis 1(H1)that the number of patients REFERRED to the self-management resource website will be larger in the intervention practices compared to control practices.

Aim 2. To test hypothesis 2 (H2) that the proportion of patients referred who GO to the patient self-management website will be larger in intervention practices compared to control practices

Aim 3. To test hypothesis 3 (H3) that the proportion of smokers who are referred who QUIT at six months will be larger among intervention compared to control because of the additional connectivity of the intervention.
