BACKGROUND: Dental visits represent an opportunity to identify and assist patients with unhealthy substance use, but little is known about how dentists are addressing patients' use of tobacco, alcohol and illicit drugs. The authors surveyed dentists to learn about the role their practices might play in providing substance-use screening and interventions. METHODS: The authors distributed a 41-item Web-based survey to all 210 dentists active in the Practitioners Engaged in Applied Research and Learning Network, a practice-based research network. The questionnaire assessed dental practices' policies and current practices, attitudes and perceived barriers to providing services for tobacco, alcohol and illicit drug use. RESULTS: One hundred forty-three dentists completed the survey (68 percent response rate). Although screening was common, fewer dentists reported that they were providing follow-up counseling or referrals for substance use. Insufficient knowledge or training was the most frequently cited barrier to intervention. Many dentists reported they would offer assistance for use of tobacco (67 percent) or alcohol or illicit drugs (52 percent) if reimbursed; respondents who treated publicly insured patients were more likely to reply that they would offer this assistance. CONCLUSIONS: Dentists recognize the importance of screening for substance use, but they lack the clinical training and practice-based systems focused on substance use that could facilitate intervention. Practical Implications. The results of this study indicate that dentists may be willing to address substance use among patients, including use of alcohol and illicit drugs in addition to tobacco, if barriers are reduced through changes in reimbursement, education and systems-level support.

The feasibility of long-term extended-release naltrexone (XR-NTX) alcohol treatment is unknown. Following an initial 12-week, single-arm, observational trial of XR-NTX plus medical management (MM) in primary care, we offered 48 additional weeks of XR-NTX treatment (12 additional monthly injections) in two public primary care clinics as a naturalistic extension study. Of 65 alcohol dependent adults initiating XR-NTX treatment, 40 (62%) completed the initial 12-week XR-NTX observational trial, and 19 (29%) continued treatment for a median of 38weeks total (range, 16-72weeks; median 8 total XR-NTX injections). Among active extension phase participants, self-reported rates of drinking days (vs. last 30 days pre-treatment baseline) were low: median 0.2 vs. 6.0drinks per day; 82 vs. 38% days abstinent; 11 vs. 61% heavy drinking days. Long-term XR-NTX treatment in a primary care MM model was feasible and may promote lasting drinking reductions or alcohol abstinence (clinical trial: NCT00620750).

INTRODUCTION: Screening and delivery of evidence-based interventions by dentists is an effective way to reduce tobacco use. However, dental visits remain an underutilized opportunity for the treatment of tobacco dependence. This is, in part, because the current reimbursement structure does not support expansion of dental providers' role in this arena. The purpose of this study was to interview dental insurers to assess attitudes toward tobacco use treatment in dental practice, pros and cons of offering dental provider reimbursement, and barriers to instituting a tobacco use treatment-related payment policy for dental providers. METHODS: Semi-structured interviews were conducted with 11 dental insurance company executives. Participants were identified using a targeted sampling method and represented viewpoints from a significant share of companies within the dental insurance industry. RESULTS: All insurers believed that screening and intervention for tobacco use was an appropriate part of routine care during a dental visit. Several indicated a need for more evidence of clinical and cost-effectiveness before reimbursement for these services could be actualized. Lack of purchaser demand, questionable returns on investment, and segregation of the medical and dental insurance markets were cited as additional barriers to coverage. Conclusions: Dissemination of findings on efficacy and additional research on financial returns could help to promote uptake of coverage by insurers. Wider issues of integration between dental and medical care and payment systems must be addressed in order to expand opportunities for preventive services in dental care settings.

ABSTRACT: BACKGROUND: Despite concerns about its health and social consequences, little is known about the prevalence of illicit opioid use in New York City. Individuals who misuse heroin and prescription opioids are known to bear a disproportionate burden of morbidity and mortality. Service providers and public health authorities are challenged to provide appropriate interventions in the absence of basic knowledge about the size and characteristics of this population. While illicit drug users are underrepresented in population-based surveys, they may be identified in multiple administrative data sources. METHODS: We analyzed large datasets tracking hospital inpatient and emergency room admissions as well as drug treatment and detoxification services utilization. These were applied in combination with findings from a large general population survey and administrative records tracking prescriptions, drug overdose deaths, and correctional health services, to estimate the prevalence of heroin and non-medical prescription opioid use among New York City residents in 2006. These data were further applied to a descriptive analysis of opioid users entering drug treatment and hospital-based medical care. RESULTS: These data sources identified 126,681 cases of opioid use among New York City residents in 2006. After applying adjustment scenarios to account for potential overlap between data sources, we estimated over 92,000 individual opioid users. By contrast, just 21,600 opioid users initiated drug treatment in 2006. Opioid users represented 4% of all individuals hospitalized, and over 44,000 hospitalizations during the calendar year. CONCLUSIONS: Our findings suggest that innovative approaches are needed to provide adequate services to this sizeable population of opioid users. Given the observed high rates of hospital services utilization, greater integration of drug services into medical settings could be one component of an effective approach to expanding both the scope and reach of health interventions for this population.

Previous research suggests that some substance users have multiple crisis detoxification visits and never access rehabilitation care. This care-seeking pattern leads to poorer outcomes and higher costs. The authors aimed to identify predictors of repeat detoxification visits by analyzing state-level data routinely collected at the time of substances use services admission. Repeat detoxification clients were more likely to be homeless, city-dwelling fee-for-service Medicaid recipients. Repeat detoxification clients were less likely than those with one admission to enter rehabilitation within 3 days. Treatment providers should aim for rapid transfer to rehabilitation and consider expanding detoxification intake data to improve risk stratification
