Implementing evidence-based alcohol interventions in a resource-limited setting: novel delivery strategies in Tomsk, Russia.

Effective implementation of evidence-based interventions in "real-world" settings can be challenging. Interventions based on externally valid trial findings can be even more difficult to apply in resource-limited settings, given marked differences-in provider experience, patient population, and health systems-between those settings and the typical clinical trial environment. Under the auspices of the Integrated Management of Physician-Delivered Alcohol Care for Tuberculosis Patients (IMPACT) study, a randomized, controlled effectiveness trial, and as an integrated component of tuberculosis treatment in Tomsk, Russia, we adapted two proven alcohol interventions to the delivery of care to 200 patients with alcohol use disorders. Tuberculosis providers performed screening for alcohol use disorders and also delivered naltrexone (with medical management) or a brief counseling intervention either independently or in combination as a seamless part of routine care. We report the innovations and challenges to intervention design, training, and delivery of both pharmacologic and behavioral alcohol interventions within programmatic tuberculosis treatment services. We also discuss the implications of these lessons learned within the context of meeting the challenge of providing evidence-based care in resource-limited settings.

Alcohol consumption among men and women with tuberculosis in Tomsk, Russia.

Drinking behavior among Russian women remains poorly described. We analyzed gender differences in alcohol use among 374 tuberculosis patients in Tomsk, Siberia. Twenty-six (28.3%) women had lifetime alcohol abuse or dependence, compared with 70.6% of men. Women with alcohol use disorders drank 12.7 +/- 14.0 standard drinks per day and > or = 34.6% drank 2 three days per week. Among individuals with a lifetime alcohol use disorder, age of onset and typical consumption did not differ significantly by gender. We conclude that Russian women with alcohol use disorders consume almost as much alcohol as men and may be at greater risk for negative social and medical consequences.

Knowledge, attitudes, and practices of physicians in Tomsk Oblast tuberculosis services regarding alcohol use among tuberculosis patients in Tomsk, Russia.

In recent years, the Russian Federation has seen a dramatic rise in morbidity and mortality from tuberculosis (TB), attributed in part to an increase in alcohol use disorders (AUDs), which are associated with worse TB treatment outcomes. This study describes the knowledge, attitudes and practices of physicians who treat TB patients in Tomsk, Russia. We conducted semistructured interviews with 16 TB physicians and 1 addiction specialist. Interviews were audiorecorded, transcribed, translated and systematically analyzed. We identified four key domains: definitions of alcohol use and abuse and physicians' knowledge, attitudes and practices regarding these problems. Physicians described patients as largely precontemplative and reluctant to seek treatment. Physicians recognized their limited knowledge in diagnosing and treating AUDs but expressed interest in acquiring these skills. Few options are currently available for treatment of AUDs in TB patients in Tomsk. These findings suggest that Tomsk physicians are aware of the need to engage AUDs in TB patients but identify a knowledge gap that restricts their ability to do so. Training TB physicians to use simple screening instruments and deliver evidence-based alcohol interventions improves TB outcomes among patients with co-occurring AUDs.

Integration of alcohol use disorders identification and management in the tuberculosis programme in Tomsk Oblast, Russia.

Alcohol use disorders (AUDs) among tuberculosis (TB) patients are associated with nonadherence and poor treatment outcomes. We developed a multidisciplinary model to manage AUDs among TB patients in Tomsk, Russia. First, we assessed current standards of care through stakeholder meetings and ethnographic work. The Alcohol Use Disorders Identification Test (AUDIT) was incorporated into routine assessment of all patients starting TB treatment. We established treatment algorithms based on AUDIT scores. We then hired specialists and addressed licensing requirements to provide on-site addictions care. Our experience offers a successful model in the management of co-occurring AUDs among patients with chronic medical problems.

The effect of initial drug resistance on treatment response and acquired drug resistance during standardized short-course chemotherapy for tuberculosis.

BACKGROUND: In Tomsk Oblast, Russian Federation, during the period of 1996-2000, most previously untreated patients with tuberculosis received standardized short-course chemotherapy, irrespective of drug-susceptibility testing results. A retrospective analysis was done to determine the effect of initial drug resistance on treatment outcome and acquired drug resistance in new patients receiving standardized short-course chemotherapy. METHODS: During the period of 1 November 1996 through 31 December 2000, a total of 2194 patients received a category 1 treatment regimen. Drug susceptibility test results for 1681 patients were available for analysis. Drug resistance patterns before and during treatment were compared for 73 patients whose culture results were persistently positive during treatment. Acquired resistance was defined as new drug resistance (during or at the end of treatment) that was not present at the beginning of treatment. RESULTS: Pretreatment drug resistance was strongly associated with treatment failure. In patients who had strains with pretreatment resistance patterns that included isoniazid or rifampin resistance, but not resistance to both, 17 (70.8%) of 24 cases involving treatment failures acquired new multidrug resistance. In patients with pretreatment pan-susceptible or streptomycin-monoresistant strains, 13 (41.9%) of 31 cases involving treatment failures acquired new multidrug resistance. CONCLUSIONS: Early diagnosis of drug-resistant tuberculosis and judicious use of second-line drugs is recommended to decrease transmission of drug-resistant strains and to prevent the creation of multidrug-resistant strains. Finally, if drug susceptibility tests are not available or results are delayed, physicians should recognize that patients who do not respond to directly observed empirical short-course chemotherapy are at high risk of having multidrug-resistant tuberculosis and should be treated accordingly.
