Access to sterile syringes through San Francisco pharmacies and the association with HIV risk behavior among injection drug users

Injection drug use practices and HIV infection among people who inject drugs in Kigali, Rwanda: a cross-sectional study

Background

In Rwanda, epidemiological data characterizing people who inject drugs (PWID) and their burden of HIV are limited. We examined injection drug use (IDU) history and practices, and HIV infection in a sample of PWID in Kigali.

Methods

From October 2019 to February 2020, 307 PWID aged ≥ 18 were enrolled in a cross-sectional study using convenience sampling in Kigali. Participants completed interviewer-administered questionnaires on IDU history and practices and HIV testing. We used Poisson regression with robust variance estimation to assess IDU practices associated with HIV infection and assessed factors associated with needle sharing in the six months preceding the study.

Results

The median age was 28 years (IQR 24–31); 81% (251) were males. Female PWID were more likely to report recent IDU initiation, selling sex for drugs, and to have been injected by a sex partner (p < 0.05). In the prior six months, heroin was the primary drug of choice for 99% (303) of participants, with cocaine and methamphetamine also reported by 10% (31/307) and 4% (12/307), respectively. In total, 91% (280/307) of participants reported ever sharing needles in their lifetime and 43% (133) knew someone who died from a drug-related overdose. HIV prevalence was 9.5% (95% CI 8.7–9.3). Sharing needles at least half of the time in the previous six months was positively associated with HIV infection (adjusted prevalence ratio (aPR) 2.67; 95% CI 1.23–5.78). Overall, 31% (94/307) shared needles and 33% (103/307) reused needles in the prior six months. Female PWID were more likely to share needles compared to males (aPR 1.68; 95% CI 1.09–2.59). Additionally, bisexual PWID (aPR 1.68; 95% CI 1.09–2.59), those who shared needles at the first injection (aPR 2.18; 95% CI 1.59–2.99), reused needles recently (aPR 2.27; 95% CI 1.51–3.43) and shared other drug paraphernalia (aPR 3.56; 95% CI 2.19–5.81) were more likely to report recent needle sharing.

Conclusion

HIV infection was common in this study. The high prevalence of needle reuse and sharing practices highlights significant risks for onward transmission and acquisition of HIV and viral hepatitis. These data highlight the urgent need for PWID-focused harm reduction services in Rwanda, including syringe services programs, safe injection education, naloxone distribution, and substance use disorder treatment programs and optimizing these services to the varied needs of people who use drugs in Rwanda.

Prevalence and Correlates of Syringe Disposal Box Use in a Philadelphia Neighborhood with High Levels of Public Drug Injection

Background: Philadelphia (Pennsylvania, USA) is facing an unprecedented public health crisis due to fentanyl use. To combat drug-related litter, the Philadelphia Department of Public Health installed 7 public syringe disposal boxes (SDB) in Kensington, the neighborhood most impacted by the opioid crisis and home to a syringe exchange. Methods: We used street- and business-intercepts to recruit residents (N=358) and business owners/staff (N=78) who completed a brief survey with two binary items measuring observing and using SDB. Multivariable logistic regression was used to assess factors independently associated with SDB observance and use. Results: 78% (340/436) observed SDB and 34.1% (116/340) had ever used SDB among those who had seen them. Unstably housed persons had 4.3 times greater odds of observing SDB (Adjusted odds ratio [aOR= 4.29; 95% confidence interval [CI]: 1.56, 11.82) and had 2.5 times greater odds of using SDB (aOR = 2.51; 95% CI: 1.33, 4.74) as did people who use opioids (aOR = 2.61; 95% CI: 1.45, 4.72). Among individuals reporting opioid use who also saw SDB (n=123), those who were unstably housed were more likely to use SDB than those with stable housing (67.8% vs 45.3%, p=.012). Conclusion: These results suggest Kensington residents, especially those who are unstably housed, use SDB once they see them in the neighborhood.

I could take the judgment if you could just provide the service: non-prescription syringe purchase experience at Arizona pharmacies, 2018

Background

Community pharmacies are important for health access by rural populations and those who do not have optimum access to the health system, because they provide myriad health services and are found in most communities. This includes the sale of non-prescription syringes, a practice that is legal in the USA in all but two states. However, people who inject drugs (PWID) face significant barriers accessing sterile syringes, particularly in states without laws allowing syringe services programming. To our knowledge, no recent studies of pharmacy-based syringe purchase experience have been conducted in communities that are both rural and urban, and none in the Southwestern US. This study seeks to understand the experience of retail pharmacy syringe purchase in Arizona by PWID.

Methods

An interview study was conducted between August and December 2018 with 37 people living in 3 rural and 2 urban Arizona counties who identified as current or former users of injection drugs. Coding was both a priori and emergent, focusing on syringe access through pharmacies, pharmacy experiences generally, experiences of stigma, and recommendations for harm reduction services delivered by pharmacies.

Results

All participants reported being refused syringe purchase at pharmacies. Six themes emerged about syringe purchase: (1) experience of stigma and judgment by pharmacy staff, (2) feelings of internalized stigma, (3) inconsistent sales outcomes at the same pharmacy or pharmacy chain, (4) pharmacies as last resort for syringes, (5) fear of arrest for syringe possession, and (6) health risks resulting from syringe refusal.

Conclusions

Non-prescription syringe sales in community pharmacies are a missed opportunity to improve the health of PWID by reducing syringe sharing and reuse. Yet, current pharmacy syringe sales refusal and stigmatization by staff suggest that pharmacy-level interventions will be necessary to impact pharmacy practice. Lack of access to sterile syringes reinforces health risk behaviors among PWID. Retail syringe sales at pharmacies remain an important, yet barrier-laden, element of a comprehensive public health response to reduce HIV and hepatitis C among PWID. Future studies should test multilevel evidence-based interventions to decrease staff discrimination and stigma and increase syringe sales.

Fentanyl test strips as an opioid overdose prevention strategy: Findings from a syringe services program in the Southeastern United States

BACKGROUND

In 2016, the number of overdose deaths involving illicitly-manufactured fentanyl (IMF) surpassed heroin and prescription opioid deaths in the United States for the first time, with IMF-involved overdose deaths increasing more than 500% across 10 states from 2013 to 2016. IMF is an extremely potent synthetic opioid that is regularly mixed with heroin and often sold to unwitting consumers. Community-based organizations have started to distribute fentanyl test strips (FTS) as a strategy to identify IMF in street purchased products. We investigated the association between FTS use and changes in drug use behavior and perceived overdose safety among a community-based sample of people who inject drugs (PWID) in the United States.

METHODS

Between September-October 2017, a total of 125 PWID completed an online survey about their most recent FTS use in Greensboro, North Carolina. Our first outcome of interest included whether PWID engaged in any of the following changes in drug use behavior after using FTS: used less than usual, administered tester shot, pushed syringe plunger slower than usual, and snorted instead of injected. Our second outcome of interest was whether PWID felt that FTS use made them feel better able to protect themselves from overdose. We conducted bivariate and multivariate analyses to determine the association between FTS use and these two outcomes.

RESULTS

Overall, 63% of the sample reported a positive FTS test result and 81% reported using FTS prior to consuming their drugs. For the outcomes, 43% reported a change in drug use behavior and 77% indicated increased perceived overdose safety by using FTS. In multivariable models adjusting for demographic and FTS correlates, PWID with a positive FTS test result had five times the odds of reporting changes in drug use behavior compared to those with a negative result. PWID who used the FTS after drug consumption were 70% less likely to report behavioral changes at subsequent drug consumption compared to those who used it before consumption. PWID who were not existing clients of the syringe services program had four times higher odds than existing clients to report increased overdose safety from using FTS.

CONCLUSIONS

We found that using FTS and receiving a positive test result was associated with changes in drug use behavior and perceptions of overdose safety. FTS may represent an effective addition to current overdose prevention efforts when included with other evidence-based strategies to prevent opioid overdose and related harm.

Factors associated with obtaining sterile syringes from pharmacies among persons who inject drugs in 20 US cities

BACKGROUND

Increased access to sterile syringes has been shown to reduce HIV risk among people who inject drugs (PWID). Where syringe services programs (SSPs) are limited, pharmacies are an important sterile syringe source. We assessed factors associated with using pharmacies as the primary source of syringes among PWID from 20 US cities.

METHODS

PWID ages ≥18 years were recruited for the 2015 National HIV Behavioral Surveillance using respondent-driven sampling. Using generalized estimating equation (GEE) models, we assessed demographic characteristics independently associated with participant-reported primary syringe source: pharmacies vs. SSPs. We calculated associations between primary syringe source and various behavioural outcomes, adjusted for participant characteristics.

RESULTS

PWID who were <30 years old, female, white, and less frequent injectors were more likely have used pharmacies as their primary syringe source. Accessing syringes primarily from pharmacies, as compared to SSPs, was associated with receptive syringe sharing and unsafe syringe disposal; using sterile syringes, recent HIV testing and participation in an HIV behavioural intervention were negatively associated with primary pharmacy use.

CONCLUSIONS

Pharmacies can play an important role in comprehensive HIV prevention among PWID. Linkage to HIV interventions and syringe disposal services at pharmacies could strengthen prevention efforts for PWID who cannot access or choose not to utilize SSPs.

A Cost-Benefit Analysis of a Potential Supervised Injection Facility in San Francisco, California, USA

Supervised injection facilities (SIFs) have been shown to reduce infection, prevent overdose deaths, and increase treatment uptake. The United States is in the midst of an opioid epidemic, yet no sanctioned SIF currently operates in the United States. We estimate the economic costs and benefits of establishing a potential SIF in San Francisco using mathematical models that combine local public health data with previous research on the effects of existing SIFs. We consider potential savings from five outcomes: averted HIV and hepatitis C virus (HCV) infections, reduced skin and soft tissue infection (SSTI), averted overdose deaths, and increased medication-assisted treatment (MAT) uptake. We find that each dollar spent on a SIF would generate US$2.33 in savings, for total annual net savings of US$3.5 million for a single 13-booth SIF. Our analysis suggests that a SIF in San Francisco would not only be a cost-effective intervention but also a significant boost to the public health system.

Merchants, samaritans, and public health workers: Secondary syringe exchanger discursive practices

BACKGROUND

Secondary syringe exchangers (SSEs) are a vital component of harm reduction efforts among persons who inject drugs (PWIDs). However, little research has explored how secondary exchange occurs, nor why SSEs do their work. This study looks at secondary exchange as an act of resilience within the PWID risk environment. It asks how secondary syringe exchangers utilize syringes to improve their mental and material well-being.

METHODS

This article draws on findings from semi-structured in-depth interviews of 30 SSEs. It is also informed by 4 years of participant observation as a volunteer and site supervisor at the San Francisco Aids Foundation syringe exchange sites, and 1 year of participant observation with SSEs and their clients.

RESULTS

This study finds that SSEs use syringes as a resource to support three discursive practices - those of merchants, public health workers, and samaritans. These discursive practices correlate to their work and educational backgrounds, and to their accounts of charging for syringes, disseminating public health information, and helping their clients in various ways.

CONCLUSION

SSEs hold heterogeneous motivations and operate in multiple contexts. Many SSEs see themselves as, and behave as, informal health care workers or helpers in their community. They could be utilized, with minimal training and encouragement, to disseminate additional harm reduction information and materials.

Drug-related deaths and the sales of needles through pharmacies

BACKGROUND

Providing needles to people who inject drugs is a well-proven public health response to the transmission of HIV and other blood borne viruses. Despite over a quarter of a century of research, new concerns about potential unintended negative consequences of needle distribution continue to emerge. Specifically, a claim was recently made that the introduction of pharmacy sales of needles was followed by an increase in overdoses in pharmacy parking lots. If true, this would have serious implications for the design of needle access programs, particularly those involving pharmacy sales of needles.

METHODS

We examine spatial relationships between drug-related deaths and pharmacies in Los Angeles County (population 9.8 million) before and after the 2007 enactment of a California law allowing pharmacy sales of needles without a prescription. Seven thousand and forty-nine drugs related deaths occurred in Los Angeles county from 2000 to 2009 inclusive. Four thousand two hundred and seventy-five of these deaths could be geocoded, and were found to be clustered at the census tract level.

RESULTS

We used three methods to examine spatial relationships between overdose death locations and pharmacy locations for two years on either side of the enactment of the pharmacy sales law, and found no statistically significant changes. Among the 711 geocodable deaths occurring in the two years following the change in law, no death was found to occur within 50m of a pharmacy which sold needles.

CONCLUSION

These results are consistent with prior studies which suggest pharmacy sales of needles improve access to needles without causing increased harms to the surrounding community.

Feasibility of providing interventions for injection drug users in pharmacy settings: a case study among San Francisco pharmacists

In addition to syringe exchange programs, pharmacies are important venues where injection drug users (IDUs) can access non-prescription syringes and other prevention interventions. This study assessed the feasibility of providing a range of interventions for IDUs in pharmacy settings. Semi-structured qualitative interviews were conducted with 23 participants (policy makers, owner/managers, dispensing pharmacists, and pharmacy staff) from independent and chain/retail pharmacies in San Francisco, California, USA. The highest level of support was for a coupon syringe program and educational materials. Several overarching themes illustrate challenges to implementing pharmacy-based preventive interventions: time, space, sufficient staff, pharmacist training, legal considerations, pharmacist attitudes toward IDUs, and cost and reimbursement issues. This study provides concrete examples of the types of preventive services that pharmacists support and consider feasible, and illustrates that pharmacists welcome the opportunity to broaden their role as critical partners in public health matters related to injection drug use.

Evaluating the impact of Mexico's drug policy reforms on people who inject drugs in Tijuana, B.C., Mexico, and San Diego, CA, United States: a binational mixed methods research agenda

Background

Policymakers and researchers seek answers to how liberalized drug policies affect people who inject drugs (PWID). In response to concerns about the failing “war on drugs,” Mexico recently implemented drug policy reforms that partially decriminalized possession of small amounts of drugs for personal use while promoting drug treatment. Recognizing important epidemiologic, policy, and socioeconomic differences between the United States—where possession of any psychoactive drugs without a prescription remains illegal—and Mexico—where possession of small quantities for personal use was partially decriminalized, we sought to assess changes over time in knowledge, attitudes, behaviors, and infectious disease profiles among PWID in the adjacent border cities of San Diego, CA, USA, and Tijuana, Baja California, Mexico.

Methods

Based on extensive binational experience and collaboration, from 2012–2014 we initiated two parallel, prospective, mixed methods studies: Proyecto El Cuete IV in Tijuana (n = 785) and the STAHR II Study in San Diego (n = 575). Methods for sampling, recruitment, and data collection were designed to be compatible in both studies. All participants completed quantitative behavioral and geographic assessments and serological testing (HIV in both studies; hepatitis C virus and tuberculosis in STAHR II) at baseline and four semi-annual follow-up visits. Between follow-up assessment visits, subsets of participants completed qualitative interviews to explore contextual factors relating to study aims and other emergent phenomena. Planned analyses include descriptive and inferential statistics for quantitative data, content analysis and other mixed-methods approaches for qualitative data, and phylogenetic analysis of HIV-positive samples to understand cross-border transmission dynamics.

Results

Investigators and research staff shared preliminary findings across studies to provide feedback on instruments and insights regarding local phenomena. As a result, recruitment and data collection procedures have been implemented successfully, demonstrating the importance of binational collaboration in evaluating the impact of structural-level drug policy reforms on the behaviors, health, and wellbeing of PWID across an international border.

Conclusions

Our prospective, mixed methods approach allows each study to be responsive to emerging phenomena within local contexts while regular collaboration promotes sharing insights across studies. The strengths and limitations of this approach may serve as a guide for other evaluations of harm reduction policies internationally.

High HIV incidence among persons who inject drugs in Pakistan: greater risk with needle sharing and injecting frequently among the homeless

Background

The incidence of HIV among persons who inject drugs (PWIDU) has fallen in many nations, likely due to successes of clean needle/syringe exchange and substance abuse treatment and service programs. However in Pakistan, prevalence rates for PWID have risen dramatically. In several cities, prevalence exceeded 20% by 2009 compared to a 2003 baseline of just 0.5%. However, no cohort study of PWID has ever been conducted.

Methods

We enrolled a cohort of 636 HIV seronegative PWID registered with three drop-in centers that focus on risk reduction and basic social services in Karachi. Recruitment began in 2009 (March to June) and PWID were followed for two years. We measured incidence rates and risk factors associated with HIV seroconversion.

Results

Incidence of HIV was 12.4 per 100 person-years (95% exact Poisson confidence interval [CI]: 10.3–14.9). We followed 474 of 636 HIV seronegative persons (74.5%) for two years, an annual loss to follow-up of <13 per 100 person years. In multivariable Cox regression analysis, HIV seroconversion was associated with non-Muslim religion (Adjusted risk ratio [ARR] = 1.7, 95%CI:1.4, 2.7, p = 0.03), sharing of syringes (ARR = 2.3, 95%CI:1.5, 3.3, p<0.0001), being homeless (ARR = 1.7, 95%CI:1.1, 2.5, p = 0.009), and daily injection of drugs (ARR = 1.1, 95%CI:1.0, 1.3, p = 0.04).

Conclusions

Even though all members of the cohort of PWID were attending risk reduction programs, the HIV incidence rate was very high in Karachi from 2009–2011. The project budget was low, yet we were able to retain three-quarters of the population over two years. Absence of opiate substitution therapy and incomplete needle/syringe exchange coverage undermines success in HIV risk reduction.

Pharmacy nonprescription syringe distribution and HIV/AIDS: a review

OBJECTIVE

To summarize current research findings on pharmacy nonprescription syringe distribution to prevent the spread of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) among injection drug users (IDUs), including research on pharmacist attitudes and behavior, drug user attitudes and behavior, and the health impact on HIV/AIDS risk behavior.

DATA SOURCES

Data were collected using PubMed and PsycINFO through July 2011. Search terms used were pharmacist or pharmacy and syringe or syringe exchange or needle or needle exchange. Two journals (Journal of Urban Health and Journal of the American Pharmacists Association) with a high number of hits were manually inspected. Reference sections for each article also were examined.

STUDY SELECTION

Studies were included if they examined attitudes toward, experiences with, or the impact of pharmacy nonprescription syringe distribution for the purpose of preventing the spread of HIV/AIDS among IDUs in the United States. Studies were excluded that mentioned these topics in passing or did not report empirical results.

DATA SYNTHESIS

47 studies were identified that met the inclusion criteria. Studies included a diverse range of perspectives, including pharmacist viewpoints, IDU attitudes, and evaluations.

CONCLUSION

According to the available literature, many pharmacists express willingness to sell and report selling syringes to customers without a prescription. IDUs show willingness to use pharmacies to obtain syringes. Finally, pharmacy syringe sale and the legalization of this practice appear to have a positive impact on HIV risk behavior. Accordingly, the nonprescription sale of syringe should be promoted. However, the literature remains incomplete and future research is required.

Factors associated with presence of pharmacies and pharmacies that sell syringes over-the-counter in Los Angeles County

Community pharmacies serve as key locations for public health services including interventions to enhance the availability of syringes sold over-the-counter (OTC), an important strategy to prevent injection-mediated HIV transmission. Little is known about the community characteristics associated with the availability of pharmacies and pharmacies that sell syringes OTC. We conducted multivariable regression analyses to determine whether the sociodemographic characteristics of census tract residents were associated with pharmacy presence in Los Angeles (LA) County during 2008. Using a geographic information system, we conducted hot-spot analyses to identify clusters of pharmacies, OTC syringe-selling pharmacies, sociodemographic variables, and their relationships. For LA County census tracts (N = 2,054), population size (adjusted odds ratio [AOR], 1.22; 95 % confidence interval [CI], 1.16, 1.28), median age of residents (AOR, 1.03; 95 % CI, 1.01, 1.05), and the percent of households receiving public assistance (AOR, 0.97; 95 % CI, 0.94, 0.99) were independently associated with the presence of all pharmacies. Only 12 % of census tracts had at least one OTC syringe-selling pharmacy and sociodemographic variables were not independently associated with the presence of OTC syringe-selling pharmacies. Clusters of pharmacies (p < 0.01) were located proximally to clusters of older populations and were distant from clusters of poorer populations. Our combined statistical and spatial analyses provided an innovative approach to assess the sociodemographic and geographic factors associated with the presence of community pharmacies and pharmacies that participate in OTC syringe sales.

The feasibility of pharmacy-based naloxone distribution interventions: a qualitative study with injection drug users and pharmacy staff in Rhode Island

This study analyzed qualitative data from a Rapid Policy Assessment and Response project to assess the feasibility of a potential pharmacy-based naloxone intervention to reduce opioid overdose mortality among injection drug users (IDUs). We conducted in-depth, semistructured interviews with 21 IDUs and 21 pharmacy staff (pharmacists and technicians). Although most participants supported the idea of a pharmacy-based naloxone intervention, several barriers were identified, including misinformation about naloxone, interpersonal relationships between IDUs and pharmacy staff, and costs of such an intervention. Implications for future pharmacy-based overdose prevention interventions for IDUs, including pharmacy-based naloxone distribution, are considered. The study's limitations are noted.

Pharmacy syringe purchase test of nonprescription syringe sales in San Francisco and Los Angeles in 2010

The two main legal sources of clean needles for illicit injection drug users (IDUs) in California are syringe exchange programs (SEPs) and nonprescription syringe sales (NPSS) at pharmacies. In 2004, California became one of the last states to allow NPSS. To evaluate the implementation of NPSS and the California Disease Prevention Demonstration Project (DPDP), we conducted syringe purchase tests in San Francisco (SF) and Los Angeles (LA) between March and July of 2010. Large differences in implementation were observed in the two cities. In LA, less than one-quarter of the enrolled pharmacies sold syringes to our research assistant (RA), and none sold a single syringe. The rate of successful purchase in LA is the lowest reported in any syringe purchase test. In both sites, there was notable variation among the gauge size available, and price and quantity of syringes required for a purchase. None of the DPDP pharmacies in LA or SF provided the requisite health information. The findings suggest that more outreach needs to be conducted with pharmacists and pharmacy staff. The pharmacies' failure to disseminate the educational materials may result in missed opportunities to provide needed harm reduction information to IDUs. The varied prices and required quantities may serve as a barrier to syringe access among IDUs. Future research needs to examine reasons why pharmacies do not provide the mandated information, whether the omission of disposal options is indicative of pharmacies' reluctance to serve as disposal sites, and if the dual opt-in approach of NPSS/DPDP is a barrier to pharmacy enrollment.

Demographic, risk, and spatial factors associated with over-the-counter syringe purchase among injection drug users

Since 2005, California law allowed over-the-counter (OTC) syringe sales pending local authorization. Although pharmacy sales of OTC syringes are associated with reduced injection-mediated risks and decreases in human immunodeficiency virus infection rates, little is known about the factors associated with syringe purchase among injection drug users (IDUs). Using a cross-sectional design, the authors applied targeted sampling to collect quantitative survey data from IDUs (n = 563) recruited in San Francisco, California, during 2008. They also compiled a comprehensive list of retail pharmacies, their location, and whether they sell OTC syringes. They used a novel combination of geographic information system and statistical analyses to determine the demographic, behavioral, and spatial factors associated with OTC syringe purchase by IDUs. In multivariate analyses, age, race, injection frequency, the type of drug injected, and the source of syringe supply were independently associated with OTC syringe purchases. Notably, the prevalence of OTC syringe purchase was 53% lower among African-American IDUs (adjusted prevalence ratio = 0.47, 95% confidence interval: 0.33, 0.67) and higher among injectors of methamphetamine (adjusted prevalence ratio = 1.35, 95% confidence interval: 1.07, 1.70). Two neighborhoods with high densities of IDUs had limited access to OTC syringes. Increased access to OTC syringes would potentially prevent blood-borne infectious diseases among IDUs.

Social, structural and behavioral determinants of overall health status in a cohort of homeless and unstably housed HIV-infected men

BACKGROUND

Previous studies indicate multiple influences on the overall health of HIV-infected persons; however, few assess and rank longitudinal changes in social and structural barriers that are disproportionately found in impoverished populations. We empirically ranked factors that longitudinally impact the overall health status of HIV-infected homeless and unstably housed men.

METHODS AND FINDINGS

Between 2002 and 2008, a cohort of 288 HIV+ homeless and unstably housed men was recruited and followed over time. The population was 60% non-Caucasian and the median age was 41 years; 67% of study participants reported recent drug use and 20% reported recent homelessness. At baseline, the median CD4 cell count was 349 cells/µl and 18% of eligible persons (CD4<350) took antiretroviral therapy (ART). Marginal structural models were used to estimate the population-level effects of behavioral, social, and structural factors on overall physical and mental health status (measured by the SF-36), and targeted variable importance (tVIM) was used to empirically rank factors by their influence. After adjusting for confounding, and in order of their influence, the three factors with the strongest negative effects on physical health were unmet subsistence needs, Caucasian race, and no reported source of instrumental support. The three factors with the strongest negative effects on mental health were unmet subsistence needs, not having a close friend/confidant, and drug use. ART adherence >90% ranked 5th for its positive influence on mental health, and viral load ranked 4th for its negative influence on physical health.

CONCLUSIONS

The inability to meet food, hygiene, and housing needs was the most powerful predictor of poor physical and mental health among homeless and unstably housed HIV-infected men in an urban setting. Impoverished persons will not fully benefit from progress in HIV medicine until these barriers are overcome, a situation that is likely to continue fueling the US HIV epidemic.

Injection drug users' perspectives on placing HIV prevention and other clinical services in pharmacy settings

In their role as a source of sterile syringes, pharmacies are ideally situated to provide additional services to injection drug users (IDUs). Expanding pharmacy services to IDUs may address the low utilization rates of healthcare services among this population. This qualitative study of active IDUs in San Francisco explored perspectives on proposed health services and interventions offered in pharmacy settings, as well as facilitators and barriers to service delivery. Eleven active IDUs participated in one-on-one semistructured interviews at a community field site and at a local syringe exchange site between February and May 2010. Results revealed that most had reservations about expanding services to pharmacy settings, with reasons ranging from concerns about anonymity to feeling that San Francisco already offers the proposed services in other venues. Of the proposed health services, this group of IDUs prioritized syringe access and disposal, clinical testing and vaccinations, and provision of methadone. Pharmacists' and pharmacy staff's attitudes were identified as a major barrier to IDUs' comfort with accessing services. The findings suggest that although IDUs would like to see some additional services offered within pharmacy settings, this is contingent upon pharmacists and their staff receiving professional development trainings that cultivate sensitivity towards the needs and experiences of IDUs.

Potential role of safer injection facilities in reducing HIV and hepatitis C infections and overdose mortality in the United States

BACKGROUND

Safer injection facilities (SIFs) reduce risks associated with injecting drugs, particularly public injection and overdose mortality. They exist in many countries, but do not exist in the United States. We assessed several ethical, operational, and public health considerations for establishing SIFs in the United States.

METHOD

We used the six-factor Kass framework (goals, effectiveness, concerns, minimization of concerns, fair implementation, and balancing of benefits and concerns), summarized needs of persons who inject drugs in the United States, and reviewed global evidence for SIFs.

RESULTS

SIFs offer a hygienic environment to inject drugs, provide sterile injection equipment at time of injection, and allow for safe disposal of used equipment. Injection of pre-obtained drugs, purchased by persons who inject drugs, happens in a facility where trained personnel provide on-site counseling and referral to addiction treatment and health care and intervene in overdose emergency situations. SIFs provide positive health benefits (reducing transmission of HIV and viral hepatitis, bacterial infections, and overdose mortality) without evidence for negative health or social consequences. SIFs serve most-at-risk persons, including those who inject in public or inject frequently, and those who do not use other public health programs. It is critical to address legal, ethical, and local concerns, develop and implement relevant policies and procedures, and assess individual- and community-level needs and benefits of SIFs given local epidemiologic data.

CONCLUSIONS

SIFs have the potential to reduce viral and bacterial infections and overdose mortality among those who engage in high-risk injection behaviors by offering unique public health services that are complementary to other interventions.

Three years after legalization of nonprescription pharmacy syringe sales in California: where are we now?

In January 2005, passage of California Senate Bill 1159 enabled California's county or city governments to establish disease prevention demonstration projects (DPDPs) through which pharmacies could subsequently register to legally sell up to 10 syringes to adults without a prescription. California's 61 local health jurisdictions (LHJs) were surveyed annually in 2005-2007 to monitor the progress of DPDP implementation and assess program coverage, facilitators, and barriers. Completed surveys were returned by mail, fax, e-mail, phone, or internet. We analyzed 2007 survey data to describe current DPDP status; data from all years were analyzed for trends in approval and implementation status. By 2007, 17 (27.9%) LHJs approved DPDPs, of which 14 (82.4%) had registered 532 (17.8%) of the 2,987 pharmacies in these 14 LHJs. Although only three LHJs added DPDPs since 2006, the number of registered pharmacies increased 102% from 263 previously reported. Among the LHJs without approved DPDPs in 2007, one (2.3%) was in the approval process, seven (16.3%) planned to seek approval, and 35 (81.4%) reported no plans to seek approval. Of 35 LHJs not planning to seek approval, the top four reasons were: limited health department time (40%) or interest (34%), pharmacy disinterest (31%), and law enforcement opposition (26%). Among eight LHJs pursuing approval, the main barriers were "time management" (13%), educating stakeholders (13%), and enlisting pharmacy participation (13%). The17 LHJs with DPDP represent 52% of California's residents; they included 62% of persons living with HIV and 59% of IDU-related HIV cases, suggesting that many LHJs with significant numbers of HIV cases have approved DPDPs. Outcome studies are needed to determine whether SB 1159 had the desired impact on increasing syringe access and reducing blood-borne viral infection risk among California IDUs.
