Background and study aims
Since smoking has a deep impact on socioeconomic inequality in illness and death, it is important that vulnerable populations of smokers be targeted with treatment. The US Public Health Service recommends that all patients be asked about their smoking at every visit, and that smokers be given brief advice to quit and referred to treatment. Initiatives to facilitate these practices include the five As (i.e., Ask, Advise, Assess, Assist, Arrange) and Ask Advise Refer (AAR). Unfortunately, primary care referrals are low, and most smokers referred fail to enroll. This study evaluated the effectiveness of the Ask Advise Connect (AAC) approach to linking smokers with treatment in a large, safety-net public healthcare system.
Who can participate?
Participants were patients who presented for care at any of the 10 clinics participating in the trial, reported any level of current smoking, and were age 18 or older.
What does the study involve?
AAC was evaluated in 10 community health clinics that are part of the Harris Health System, a large multi-specialty safety-net medical organization with three hospitals, two specialty clinics, 13 community health clinics, and eight school-based clinics. The Harris Health System community health clinics serve nearly 200,000 unique patients over the age of 18 per year, and the majority of patients (90%) are members of racial/ethnic minority groups. Nearly half have annual household incomes below the poverty level and more than 80% qualify for Harris Health Systems charity care program or other insurance programs for the poor (e.g., Medicaid). Their secure electronic health record (EHR) system was in place before the start of this study.
Five community health clinics were randomly allocated to AAC (intervention) and five were randomized to a control condition (AAR). In both AAC and AAR, Licensed Vocational Nurses (LVNs) were trained to assess and record the smoking status of all patients at all visits in the EHR when vital signs were collected. They were also trained to provide all patients reporting current smoking with brief advice to quit consistent with the Guideline. An initial 30-minute training session on how to assess smoking status, deliver brief advice to quit, and connect (in AAC) or refer (in AAR) patients to the Quitline was held at the beginning of the study. The intervention delivered by the Quitline comprised five proactive telephone calls that were delivered over a period of up to 3 months and the total study duration was 19 months.
What were the possible benefits and risks of participating?
Participants were provided with referrals to smoking cessation programs other than the Quitline when desired or appropriate. There were minimal risks associated with this study. It was unlikely that connections and referrals to the Quitline, or counseling provided by the Quitline, would lead to any potential legal, social or psychological problems.
Where is the study run?
This study was a collaboration between the University of Texas MD Anderson Cancer Center, the Harris Health System and the Texas Quitline. Data were collected at the Harris Health System and sent to MD Anderson. Data regarding Quitline treatment enrollment were collected by the Texas Quitline and provided to MD Anderson.
When is the study starting and how long is it expected to run for?
The intervention period for AAC and AAR within each clinic was 18 months. All data were collected between June 2010 and March 2012.

Scientific title | Dissemination of a smoking Quitline to the underserved: a group-randomized trial |
Study objectives | It was hypothesized that Ask Advise Connect (AAC) would have greater reach than Ask Advise Refer (AAR) because many of the barriers to successful treatment enrollment were eliminated in AAC relative to AAR. It was also hypothesized that the efficacy of AAR would exceed that of AAC because smokers who contacted the Quitline would be more motivated to enroll in cessation treatment. Finally, it was hypothesized that the impact of AAC would greatly exceed the impact of AAR because of its much broader reach.

Ethics approval(s) | The study was originally approved by the MD Anderson IRB on November 7, 2008. It was approved by the Texas Department of State Health Services IRB on March 17, 2009. The protocol was approved by the Harris Health System IRB on November 12, 2009. |

Intervention | Clinics were randomized to AAC (n=5; intervention) or AAR (n=5; control). Licensed Vocational Nurses (LVNs) were trained to assess and record the smoking status of all patients at all visits in the electronic health record (EHR). Smokers were given brief advice to quit. In AAC, the names and phone numbers of smokers who agreed to be connected were sent electronically to the Texas Quitline daily, and patients were proactively called within 48 hours. In AAR, smokers were offered a Quitline referral card and encouraged to call on their own. The intervention delivered by the Quitline comprised five proactive telephone calls that were delivered over a period of up to 3 months. |
Intervention type | Other |
Primary outcome measure | Impact was defined as the proportion of identified smokers that enrolled in treatment. 1. Whether or not smokers agreed to be connected (AAC) with or referred (AAR) to the Quitline at the time of the clinic visit 2. Whether or not those individuals enrolled in the treatment program offered by the Quitline. Quitline counsellors attempted to reach participants within 48 hours of receiving their contact information, and they made five attempts to reach each participant before declaring them unreachable. The time period over which the call attempts were made spanned a period of approximately 2 weeks. |
Secondary outcome measures | 1. Reach was defined as the number of smokers visiting the clinics that talked with the Quitline / total number of smokers that visited the clinics. 2. Efficacy was defined as the total number of smokers visiting the clinics that enrolled in treatment with the Quitline / total number of smokers visiting the clinics that talked with the Quitline. |
