Brief summary
This add-on study of providing tobacco, alcohol and other drug screening, brief intervention and referral for treatment to a primary care high risk diabetic population leverages the existing research resources of a funded parent project Duke University CMS Innovation Award Southeastern Diabetes initiative (PI: Robert M. Califf, MD) to explore the feasibility of implementing Screening for substance use, Brief Intervention, and Referral to Treatment services in Primary Care (SBIRT-PC) and to examine the effects of substance use status on diabetes health care outcomes. This pilot study also examines the feasibility of the CTN's common data element algorithms of SBIRT for illicit and nonmedical drug use in the primary care setting.
Detailed description
Duke University Translational Medicine Institute has received funds from the Bristol-Myers Squibb Foundation and the Centers for Medicare and Medicaid Services (2012-2016) to augment existing standard of care for patients with diabetes in community-based medical settings in order to achieve goals of better health, better health care, and reduced costs (Duke University CMS Innovation Award Southeastern Diabetes initiative; Principal Investigator, Robert M. Califf, MD). Its goals are to (1) improve population-level diabetes management, health outcomes, and quality of life for diagnosed and undiagnosed adults living with type 2 diabetes, (2) reduce disparities in diabetes management, health outcomes and quality of life for adults living with type 2 diabetes, and (3) reduce healthcare costs associated with type 2 diabetes. This already funded diabetes care project provides a cost-effective platform for conducting an add-on project to examine the feasibility of the CTN's clinical decision support algorithms for SBIRT in primary care settings, as the study team can leverage existing organizational and research infrastructure to facilitate the completion of the study. The add-on study is supported by strong rationale, including the fact that primary care settings serve as common points of contact for adults and provide many opportunities to detect drug misuse and to intervene early in low or mild severity (better outcomes), which in turn may reduce substance use, increase awareness and drug-medication interactions, enhance patient medication adherence, and decrease high inpatient costs and repeat emergency department visits.
Interventions
Patients receive a referral to treatment for substance abuse, with up to 2 follow-up phone calls. Patients are re-screened at followup visits.
Patients receive a brief intervention aimed at reducing substance use, and are re-screened at followup visits.

| Measure | Time frame | Description |
|---|---|---|
| Cigarette Smoking Status and Nicotine Dependence | Baseline, Six Month Follow-up | Results from Fagerstrom Test for Nicotine Dependence. The Fagerström Test for Nicotine Dependence is a standard instrument for assessing the intensity of physical addiction to nicotine. It contains six items that evaluate the quantity of cigarette consumption, the compulsion to use, and dependence. The items are summed to yield a total score of 0-10. The higher the total Fagerström score, the more intense is the patient's physical dependence on nicotine. |
| Alcohol Use Status | Baseline, Six Month Follow-up | Results of AUDIT-C survey. The AUDIT-C is a 3-item alcohol screen that can help identify people who are hazardous drinkers or have active alcohol use disorders. AUDIT-C is scored on a scale of 0-12. The higher the score, the more likely it is that the person's drinking is affecting his/her safety |
| Drug Use Status and Frequency | Baseline, Six Month Follow-up | Results of DAST-10 survey to determine use of illicit or nonmedical drugs.The Drug Abuse Screening Test (DAST-10) is a 10-item brief screening tool that assesses drug use, not including alcohol or tobacco use, in the past 12 months. Each question requires a yes or no response, and the tool can be completed in less than 8 minutes. DAST-10 scores on a 10-point scale. A score of 0 indicates no problems and 10 indicates a severe level of problems are associated with drug abuse. |
| Percentage of Participants Who Reported Substance Use at 6 Month | Baseline, Six Month Follow-up | For SBI and SBIRT groups: Proportion of baseline substance users (SBI, SBIRT) who continue substance use during the study (self reported) For S group: Proportion of baseline non-users (S) who report substance use during follow-up visit |
| Treatment for Drug Use or Alcohol | Baseline, Six Month Follow-up | Percentage of patients who received substance abuse or alcohol treatment (self reported) |

Participant flow
Recruitment details
Based on the results of the baseline substance use screen for the parent Southeastern Diabetes Initiative (SEDI) study at the Durham site, participants were categorized into three groups: Minimal-risk Screen (S) Group; At-risk Screen & Brief Intervention (SBI) Group; and, High-risk Screen, Brief Intervention, & Referral to Treatment (SBIRT) Group.
Pre-assignment details
The clinical team consented 134 adults (84% of the eligible patients) for the SBIRT study. Of the 134 adults consented (enrolled), 36 are not accounted for in the results section (do not have baseline data).
