Policing Drug Users in Russia: Risk, Fear, and Structural Violence

Anya Sarang; Tim Rhodes; Nicolas Sheon; Kimberly Page

We undertook qualitative interviews with 209 injecting drug users (IDUs) (primarily heroin) in three Russian cities: Moscow, Barnaul, and Volgograd. We explored IDUs accounts of HIV and health risk. Policing practices and how these violate health and self, emerged as a primary theme. Findings show that policing practices violate health and rights directly, but also indirectly, through the reproduction of social suffering. Extrajudicial policing practices produce fear and terror in the day-to-day lives of drug injectors, and ranged from the mundane (arrest without legal justification; the planting of evidence to expedite arrest or detainment; and the extortion of money or drugs for police gain) to the extreme (physical violence as a means of facilitating “confession” and as an act of “moral” punishment without legal cause or rationale; the use of methods of “torture”; and rape). We identify the concept of police bespredel—living with the sense that there are “no limits” to police power—as a key to perpetuating fear and terror, internalized stigma, and a sense of fatalist risk acceptance. Police besprediel is analyzed as a form of structural violence, contributing to “oppression illness.” Yet, we also identify cases of resistance to such oppression, characterized by strategies to preserve dignity and hope. We identify hope for change as a resource of risk reduction as well as escape, if only temporarily, from the pervasiveness of social suffering. Future drug use(r)-related policies, and the state responses they sponsor, should set out to promote public health while protecting human rights, hope, and dignity.

Objectives:To test the efficacy and acceptability of a single-session personalized cognitive counseling (PCC) intervention delivered by paraprofessionals during HIV voluntary counseling and testing. Methods:HIV-negative men who have sex with men (MSM; n = 336) were randomly allocated to PCC or usual counseling (UC) between October 2002 and September 2004. The primary outcome was the number of episodes of unprotected anal intercourse (UAI) with any nonprimary partner of nonconcordant HIV serostatus in the preceding 90 days, measured at baseline, 6 months, and 12 months. Impact was assessed as “intent to treat” by random-intercept Poisson regression analysis. Acceptability was assessed by a standardized client satisfaction survey. Results:Men receiving PCC and UC reported comparable levels of HIV nonconcordant UAI at baseline (mean episodes: 4.2 vs. 4.8, respectively; P = 0.151). UAI decreased by more than 60% to 1.9 episodes at 6 months in the PCC arm (P < 0.001 vs. baseline) but was unchanged at 4.3 episodes for the UC arm (P = 0.069 vs. baseline). At 6 months, men receiving PCC reported significantly less risk than those receiving UC (P = 0.029 for difference to PCC). Risk reduction in the PCC arm was sustained from 6 to 12 months at 1.9 (P = 0.181), whereas risk significantly decreased in the UC arm to 2.2 during this interval (P < 0.001 vs. 6 months; P = 0.756 vs. PCC at 12 months). Significantly more PCC participants were “very satisfied” with the counseling experience (78.2%) versus UC participants (59.2%) (P = 0.002). Conclusions:Both interventions were effective in reducing high-risk sexual behavior among MSM repeat testers. PCC participants demonstrated significant behavioral change more swiftly and reported a more satisfying counseling experience than UC participants.

Abstract Antiretroviral nonadherence is a strong determinant of virologic failure and is negatively correlated with survival. HIV-positive African American youth have lower antiretroviral adherence and treatment engagement than other populations. We assessed the feasibility and acceptability of a telehealth (remote videoconferencing) medication counseling intervention as an innovative approach to address these disparities. HIV-positive African American youth (18-29 years old) on antiretrovirals were enrolled in a telehealth medication counseling session, followed by a semi-structured qualitative interview to explore likes/dislikes of the format, modality, and content; potential impact on adherence; privacy issues; and interaction quality. Fourteen participants with a mean age of 24 years, who were 86% male, and had a mean self-reported adherence in the past month of 89%, were interviewed. Participants stated that they liked telehealth, would use it if offered in clinic/research settings, and indicated that their privacy was maintained. Participants described telehealth as convenient and efficient, with positive impact on their knowledge. Telehealth provided a modality to interact with providers that participants described as less intimidating than in-person visits. Telehealth is feasible and acceptable for delivering medication counseling to HIV-positive African American youth when conducted in a controlled clinical setting and may improve quality of patient-provider dialogue. Use of telehealth may lead to more disclosure of treatment difficulties, increased patient comfort, and improved health education.

The aim of this study was to examine the meaning of significantly higher proportions of positive test results through outreach HIV/sexually transmitted infection testing programmes at gay bathhouses compared with clinic programmes among high-risk men who have sex with men. We conducted a random digit dial survey of men who have sex with men in New York, Los Angeles, Chicago, and San Francisco. Half of the men in the sample did not test in the past year. Among those who did not test, a sizeable minority (17%) reported engaging in high-risk sexual behaviour with a casual or secondary partner. Over half of these non-testing, high-risk men went to bathhouses. These findings strongly support the potential value of locating outreach-testing programmes in bathhouses. Although further studies are necessary, such programmes have the potential to increase testing among the high-risk segment of the population. This is particularly noteworthy given that many men among those who do not test regularly engage in high-risk behaviours.

BackgroundSmokers over the age of 45 are the only group with an increase in smoking prevalence, are the least likely to quit smoking, and bear most of the burden of tobacco-related disease. Research characterizing older adult perceptions of warning labels and anti-tobacco messages has not been reported in the literature. The purpose of this study was to describe whether older smokers perceived warning labels and anti-tobacco messages as effective for the promotion of smoking cessation. A secondary aim was to explore what types of messages and message delivery formats are most relevant to older adult smokers.MethodsThis focus group study is part of a larger study to characterize older smokers’ perceptions of the risks and benefits associated with conventional and emerging tobacco products and determine the extent to which these perceptions relate to exposure to pro- and anti-tobacco messages. From April 2013 to August 2014 we conducted eight focus groups with 51 current and former smokers a focus group study in urban and suburban California. A semi-structured format about current use of conventional and emerging tobacco products was used. Participants were asked to recall and comment on examples of warning labels and anti-tobacco messages. Data were transcribed and thematically coded.ResultsWarning labels and anti-smoking messages were seen as ineffective for smoking cessation motivation among older California smokers. Positive framed anti-tobacco messages were identified as most effective. Text-only warnings were seen as ineffective due to desensitizing effects of repeated exposure. Negative messages were described as easy to ignore, and some trigger urges to smoke. Older adults are knowledgeable about the risks and health effects of smoking. However, they tend to be less knowledgeable about the benefits of cessation and may underestimate their ability to quit.ConclusionThese findings suggest that messages with a positive frame that outline immediate and long-term benefits of cessation would be an effective approach for long-term smokers.Current anti-tobacco messaging was generally not seen as effective for smoking cessation among long-term smokers.

Adolescents often engage in concurrent sexual partnerships as part of a developmental process of gaining experience with sexuality. The authors qualitatively examined patterns of concurrency and variation in normative and motivational influences on this pattern of sexual partnering among African American adolescents (31 males; 20 females), ages 15 to 17 years. Using content analysis, gender and contextual differences in social norms and motivations for concurrency were explored. Findings describe the normative influences on adolescent males and females with regard to sexual concurrency and the transfer of these norms from one generation to the next.

From questionnaire to conversation: A structural intervention to improve HIV test counseling

Nicolas Sheon; Seung Hee Lee; Shelley Facente

OBJECTIVE We describe the effects of structural intervention to enhance the quality of HIV test counseling interaction with men who have sex with men (MSM) in San Francisco. METHODS Audio recordings of 28 rapid HIV test sessions by seven counselors were collected in two phases: before and after implementation of a waiting room intervention prior to the session. The sessions were analyzed using sequence maps to visualize and compare the sequence and distribution of four activities: counseling, information delivery, data collection, and sample collection. RESULTS Prior to the intervention, counselors and clients often oriented to data collection about the clients past risk as if it were a survey. In sessions recorded after the intervention, questions about past risk were dispersed throughout the session and embedded within an elaborated discussion of the clients particular life circumstances. CONCLUSION Direct observation with the aid of sequence maps illuminates the ways that counselors and clients collaboratively orient to various tasks. PRACTICE IMPLICATIONS We demonstrated the feasibility of a structural intervention that improved the quality of both counseling and the accuracy of client risk data without requiring additional session time or counselor training.

ABSTRACT Background: Emergency Medical Service (EMS) providers are tasked with rapid evaluation, stabilization, recognition, and transport of acute stroke patients. Although prehospital stroke scales were developed to assist with stroke recognition, unrecognized challenges exist in the prehospital setting that hinder accurate assessment of stroke. The goal of this qualitative study was to systematically understand the challenges and barriers faced by paramedics in recognizing stroke presentations in the field. Methods: Paramedics from 12 EMS agencies serving a mix of rural, suburban, and urban communities in the State of California participated in five focus group discussions. Group size ranged from 3–8, with a total of 28 participants. Demographics of the participants were collected and focus group recordings were transcribed verbatim. Transcripts were subjected to deductive and inductive coding, which identified recurrent and divergent themes. Results: Strong consensus existed around constraints to prehospital stroke recognition; participants cited the diversity of stroke presentations, linguistic diversity, and exam confounded by alcohol and or drug use as barriers to initial evaluation. Also, lack of educational feedback from hospital staff and physicians and continuing medical education on stroke were reported as major deterrents to enhancing their diagnostic acumen. Across groups, participants reported attempting to foster relationships with hospital personnel to augment their educational needs, but this was easier for rural than urban providers. Conclusions: While challenges to stroke recognition in the field were slightly different for rural and urban EMS, participants concurred that timely, systematic feedback on individual patients and case-based training would strengthen early stroke recognition skills.
