Is crime associated with over-the-counter pharmacy syringe sales? Findings from Los Angeles, California

Community pharmacists' attitudes toward and practice of pharmacy-based harm reduction services in Pittsburgh, PA: a descriptive survey

BACKGROUND

In Pittsburgh, PA, legal changes in recent decades have set the stage for an expanded role for community pharmacists to provide harm reduction services, including distributing naloxone and non-prescription syringes (NPS). In the wake of the syndemics of the COVID-19 pandemic and worsening overdose deaths from synthetic opioids, we examine knowledge, attitudes, and practices of harm reduction services among community pharmacists in Pittsburgh and identify potential barriers of expanded pharmacy-based harm reduction services.

METHODS

We provided flyers to 83 community pharmacies within a 5-mile radius of the University of Pittsburgh Medical Center to recruit practicing community pharmacists to participate in an anonymous electronic survey. We used a 53-question Qualtrics survey consisting of multiple-choice, 5 or 6 point-Likert scale, and open-ended questions adapted from 5 existing survey instruments. Survey measures included demographics, knowledge, attitudes, and practices of harm reduction services (specifically naloxone and NPS provision), and explored self-reported barriers to future implementation. Data was collected July-August 2022. We conducted descriptive analysis using frequencies and proportions reported for categorical variables as well as means and standard deviations (SD) for continuous variables. We analyzed open-ended responses using inductive content analysis.

RESULTS

Eighty-eight community pharmacists responded to the survey. 90% of participants agreed pharmacists had a role in overdose prevention efforts, and 92% of participants had previously distributed naloxone. Although no pharmacists reported ever refusing to distribute naloxone, only 29% always provided overdose prevention counseling with each naloxone distributed. In contrast, while 87% of participants had positive attitudes toward the usefulness of NPS for reducing disease, only 73% of participants ever distributed NPS, and 54% had refused NPS to a customer. Participants endorsed a lack of time and concerns over clientele who used drugs as the most significant barriers to offering more comprehensive harm reduction services.

CONCLUSIONS

Our findings highlight that while most community pharmacists have embraced naloxone provision, pharmacy policies and individual pharmacists continue to limit accessibility of NPS. Future expansion efforts for pharmacy-based harm reduction services should not only address the time and labor constraints identified by community pharmacists, but also fear-based policy and stigma toward people who inject drugs and harm reduction more broadly.

Attitudes, beliefs, knowledge, and practices for over-the-counter syringe sales in community pharmacies: A systematic review

BACKGROUND

Community pharmacies are an important resource for people who inject drugs (PWID) to purchase over-the-counter (OTC) syringes. Access to sterile injection equipment can reduce the transmission of blood-borne illnesses. However, pharmacists and their staff ultimately use discretion over sales.

OBJECTIVE

To identify staff attitudes, beliefs, knowledge, and practices in the sale of OTC syringes in community pharmacies.

METHODS

This systematic review was reported according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and registered with PROSPERO (CRD42022363040). We systematically searched PubMed, Embase, and Scopus from inception to September 2022. The review included peer-reviewed empirical studies regarding OTC syringe sales among community pharmacy staff (pharmacists, interns, and technicians). We screened records and extracted data using a predefined data extraction form. Findings were narratively synthesized, and critical appraisal was conducted using the Mixed Methods Appraisal Tool.

RESULTS

A total of 1895 potentially relevant articles were identified, and 35 were included. Most studies (23; 63.9%) were cross-sectional descriptive designs. All studies included pharmacists, with seven (19.4%) also including technicians, two (5.6%) including interns, and four (11.1%) including other staff. Studies found relatively high support among respondents for harm reduction-related services within community pharmacies, but less common reports of staff engaging in said services themselves. When studies investigated the perceived positive or negative impacts of OTC syringe sales, prevention of blood-borne illness was widely understood as a benefit, while improper syringe disposal and safety of the pharmacy and its staff commonly reported as concerns. Stigmatizing attitudes/beliefs toward PWID were prevalent across studies.

CONCLUSION

Community pharmacy staff report knowledge regarding the benefits of OTC syringes, but personal attitudes/beliefs heavily influence decisions to engage in sales. Despite support for various syringe-related harm reduction activities, offerings of services were less likely due to concerns around PWID.

The Role of Nonprescription Syringe Sales in Ending the Human Immunodeficiency Virus Epidemic

In 2019, the executive branch of the United States released "Ending the Human Immunodeficiency Virus (HIV) Epidemic: A Plan for America" (EHE). EHE proposes to end the HIV epidemic in the United States by 2030. To do so requires a multifaceted effort from all health care providers addressing every possible avenue of HIV transmission. An important aspect of this mission is to increase access to sterile syringes for people who inject drugs (PWID). For many PWID, access to Syringe Service Programs is limited because of hours, location, and state laws. Pharmacies are able to provide clean syringes in a safe, clean, climate-controlled atmosphere with access to a health professional. Although published research shows pharmacist ambivalence toward the nonprescription sales of syringes, pharmacist involvement in states with established guidance and support from departments of health suggests that pharmacists are interested in this public health effort. However, without proper support from departments of health and access to training on the dignified delivery of services, pharmacies will continue to be an ineffective avenue for prevention of HIV spread through the provision of sterile syringes.

Application and utility of geographic information systems in pharmacy specific health research: A scoping review

BACKGROUND

Geographic Information Systems (GIS) are considered essential tools to analyze spatially referenced health data.

OBJECTIVES

The purpose of this scoping review is to describe how GIS is used in pharmacy specific health research.

METHODS

During July 2020, the following databases were searched: EMBASE, MEDLINE (PubMed), Web of Science and Scopus. The search strategy included terms relating to spatial analysis and pharmacy. Studies were considered eligible if they involved the use of GIS and focused on pharmacies. A narrative and tabular synthesis of the results was carried out, structured around the spatial analysis methods utilized across studies, as well as the characteristics of pharmacies evaluated in studies.

RESULTS

After a review of 6967 sources, 48 studies were included in this review. Twenty-nine studies were conducted in the United States (60.4%) and thirty-six focused on accessibility (75.0%; n = 36). Twenty-two studies investigated the relationship between sociodemographic aspects of the population and the accessibility and availability of pharmacies (45.8%). Twelve studies (25.0%) performed distance analysis and six studies (12.5%) performed geostatistical analysis. Community pharmacies were the setting evaluated most frequently, with over-the-counter selling products being the most evaluated pharmacy variable (13.3%; n = 6). Population density (58.3%; n = 28), income indicators (43.8%; n = 21) and minority community composition rates (41.7%; n = 20) were the most used population variables.

CONCLUSIONS

GIS have been increasingly used in pharmacy specific health research. Generally, research has sought to identify potential barriers to access and their effects on the population. Future research may benefit by utilizing robust spatial methods and applications across countries outside of the United States. Doing so could help to confirm the impact of sociodemographic characteristics on the availability and/or accessibility of pharmacies globally.

Prevalence and correlates of receptive syringe-sharing among people who inject drugs in rural Appalachia

BACKGROUND AND AIMS

Syringe-sharing significantly increases the risk of HIV and viral hepatitis acquisition among people who inject drugs (PWID). Clearer understanding of the correlates of receptive syringe-sharing (RSS) is a critical step in preventing bloodborne infectious disease transmission among PWID in rural communities throughout the United States. This study aimed to measure the prevalence and correlates of RSS among PWID in a rural county in Appalachia.

DESIGN

Observational, cross-sectional sample from a capture-recapture parent study.

SETTING

Cabell County, West Virginia (WV), USA, June-July 2018.

PARTICIPANTS

The sample was restricted to people who reported injecting drugs in the past 6 months (n = 420). A total of 180 participants (43%) reported recent (past 6 months) RSS. Participants reported high levels of homelessness (56.0%), food insecurity (64.8%) and unemployment (66.0%).

MEASUREMENTS

The main outcome was recent re-use of syringes that participants knew someone else had used before them. Key explanatory variables of interest, selected from the risk environment framework, included: unemployment, arrest and receipt of sterile syringes from a syringe services program (SSP). Logistic regression was used to determine correlates of recent RSS.

FINDINGS

PWID reporting recent RSS also reported higher prevalence of homelessness, food insecurity and unemployment than their non-RSS-engaging counterparts. In adjusted analyses, correlates of RSS included: engagement in transactional sex work [adjusted odds ratio (aOR) = 2.27, 95% confidence interval (CI) = 1.26-4.09], unemployment (aOR = 1.67, 95% CI = 1.03-1.72), number of drug types injected (aOR = 1.33, 95% CI = 1.15-1.53) and injection in a public location (aOR = 2.59, 95% CI = 1.64-4.08). Having accessed sterile syringes at an SSP was protective against RSS (aOR = 0.57, 95% CI = 0.35-0.92).

CONCLUSION

The prevalence of receptive syringe-sharing among people who inject drugs in a rural US county appears to be high and comparable to urban-based populations. Receptive syringe-sharing among people who inject drugs in a rural setting appears to be associated with several structural and substance use factors, including unemployment and engaging in public injection drug use. Having recently acquired sterile syringes at a syringe services program appears to be protective against receptive syringe sharing.

Pharmacy on-site overdose protocols and prevention of overdose

BACKGROUND

Opioid overdose is a preventable injury leading to high morbidity and premature mortality in communities across the United States. Overdoses take place where people use drugs, including commercial and public locations like community pharmacies, and necessitate swift detection and response to avoid harm and, even more seriously, death. The presence of emergency and safety protocols improves occupational health and safety for all in the workplace. The aim of this study was to assess the prevalence of experience with on-site pharmacy overdose and to explore pharmacist and site characteristics associated with having a known protocol for responding to on-site overdose emergencies.

Methods: An anonymous, online survey about naloxone provision and opioid safety was delivered by email, through professional pharmacy associations and continuing education attendance lists, to 3,100 pharmacists in Massachusetts and Rhode Island between October 2017 and January 2018. Survey items gauged socio-demographics, practice site characteristics, safer opioid dispensing and naloxone provision. Summary statistics and bivariate analyses were conducted to describe characteristics associated with items pertaining to on-site overdose policy awareness.

Results: Of the 357 respondents (11.5% response rate), 154 (5.0%) answered the questions of interest: 17.5% reported having at least one suspected overdose on-site at their practice location, while 42.9% reported that they were knowledgeable about and could locate at their practice location an on-site overdose protocol detailing how to respond to an overdose. Pharmacists who were knowledgeable about protocols were also more likely to offer naloxone to patients (p = 0.02) and did not practice at a chain pharmacy (p = 0.01).

Conclusions: Community pharmacies that stock and distribute naloxone are key parts of community efforts to address the opioid crisis. Pharmacies and other healthcare settings should develop and implement on-site overdose response protocols and cultivate a norm of naloxone provision to patients.

Leveraging the role of community pharmacists in the prevention, surveillance, and treatment of opioid use disorders

The global rise in opioid-related harms has impacted the United States severely. Current efforts to manage the opioid crisis have prompted a re-evaluation of many of the existing roles in the healthcare system, in order to maximize their individual effects on reducing opioid-associated morbidity and preventing overdose deaths. As one of the most accessible healthcare professionals in the US, pharmacists are well-positioned to participate in such activities. Historically, US pharmacists have had a limited role in the surveillance and treatment of substance use disorders. This narrative review explores the literature describing novel programs designed to capitalize on the role of the community pharmacist in helping to reduce opioid-related harms, as well as evaluations of existing practices already in place in the US and elsewhere around the world. Specific approaches examined include strategies to facilitate pharmacist monitoring for problematic opioid use, to increase pharmacy-based harm reduction efforts (including naloxone distribution and needle exchange programs), and to involve community pharmacists in the dispensation of opioid agonist therapy (OAT). Each of these activities present a potential means to further engage pharmacists in the identification and treatment of opioid use disorders (OUDs). Through a careful examination of these approaches, we hope that new strategies can be adopted to leverage the unique role of the community pharmacist to help reduce opioid-related harms in the US.

How Do Social Capital and HIV/AIDS Outcomes Geographically Cluster and Which Sociocontextual Mechanisms Predict Differences Across Clusters?

BACKGROUND

Place of residence has been associated with HIV transmission risks. Social capital, defined as features of social organization that improve efficiency of society by facilitating coordinated actions, often varies by neighborhood, and hypothesized to have protective effects on HIV care continuum outcomes. We examined whether the association between social capital and 2 HIV care continuum outcomes clustered geographically and whether sociocontextual mechanisms predict differences across clusters.

METHODS

Bivariate Local Moran's I evaluated geographical clustering in the association between social capital (participation in civic and social organizations, 2006, 2008, 2010) and [5-year (2007-2011) prevalence of late HIV diagnosis and linkage to HIV care] across Philadelphia, PA, census tracts (N = 378). Maps documented the clusters and multinomial regression assessed which sociocontextual mechanisms (eg, racial composition) predict differences across clusters.

RESULTS

We identified 4 significant clusters (high social capital-high HIV/AIDS, low social capital-low HIV/AIDS, low social capital-high HIV/AIDS, and high social capital-low HIV/AIDS). Moran's I between social capital and late HIV diagnosis was (I = 0.19, z = 9.54, P < 0.001) and linkage to HIV care (I = 0.06, z = 3.274, P = 0.002). In multivariable analysis, median household income predicted differences across clusters, particularly where social capital was lowest and HIV burden the highest, compared with clusters with high social capital and lowest HIV burden.

DISCUSSION

The association between social participation and HIV care continuum outcomes cluster geographically in Philadelphia, PA. HIV prevention interventions should account for this phenomenon. Reducing geographic disparities will require interventions tailored to each continuum step and that address socioeconomic factors such as neighborhood median income.

Barriers to Access to Sterile Syringes as Perceived by Pharmacists and Injecting Drug Users: Implications for Harm Reduction in Lebanon

BACKGROUND

Access to sterile syringes to injecting drug users (IDU) reduces sharing behavior and prevents the transmission of HIV.

OBJECTIVES

To describe the barriers to access to sterile syringes for IDUs in Lebanon from the perspectives of pharmacists and IDUs.

METHODS

in this qualitative study conducted in Lebanon, data were collected from 72 syringe purchase tests at pharmacies, 64 interviewees with pharmacists and 2 focus groups with injecting drug users. Two independent researchers analyzed the verbatim transcripts.

RESULTS

Results revealed that pharmacists often deny access to sterile syringes to IDUs who are frequently stigmatized and intimidated at pharmacies. While no large gender differences in pharmacists' attitudes and practices were observed, inequalities in syringe access were noticed with men IDUs more often denied purchase. Pharmacists had several barriers to sell syringes to IDUs including fear of disease spread, increased drug use, inappropriately discarded syringes, staff and customer safety, and business concerns. IDUs had several challenges to purchase syringes including stigmatization, intimidation, physical harassment, concern to reveal identity, fear of arrest and syringe price abuse.

CONCLUSIONS

Identifying the barriers to and facilitators of access to sterile syringes to IDUs is important to guide the development of efficient policies. Findings implicate the importance of empowering IDUs to purchase syringes at pharmacies through reducing the negative attitude towards IDUs and strengthening pharmacists' role in the promotion of health of IDUs. Findings also suggest that the habit of syringe sharing would decrease if the legal and cultural barriers to access are reduced.

Self-reported participation in voluntary nonprescription syringe sales in California's Central Valley

OBJECTIVES

California Senate Bill 41 (SB41), effective January 2012, is a human immunodeficiency virus/hepatitis C virus prevention measure designed to expand syringe access among injection drug users (IDUs) by allowing pharmacies to sell syringes without a prescription. This study assesses self-reported implementation of SB41 and characterizes barriers amenable to intervention.

DESIGN

Interviewer-administered survey.

SETTING AND PARTICIPANTS

Fresno and Kern Counties, CA. Pharmacists and other pharmacy staff (n = 404) at 212 pharmacies.

OUTCOME MEASURE

Self-reported nonprescription pharmacy sales to known or suspected IDUs.

RESULTS

Overall, 29.3% of participants said their pharmacy would sell nonprescription syringes to a known or suspected IDU, whereas a far higher proportion (79.3%) would sell nonprescription syringes to a person with diabetes. More than one-half said that their pharmacy requires nonprescription syringe purchasers to enter their signature and name and address in a log book although that is not required under SB41. Fewer than 2 out of 3 participants (61.1%) knew that it is legal to sell nonprescription syringes to IDUs. That knowledge, as well as having syringe sales practices based on both store policy and discretion, were positively associated with IDU syringe sales after controlling for other factors. Working at an independent pharmacy, agreeing that only people with "medical conditions" such as diabetes should be able to buy syringes, and viewing syringe sales to IDUs as "not good business" were independently but negatively associated with IDU syringe sales.

CONCLUSION

This study complements an earlier syringe purchase trial documenting low participation in voluntary nonprescription syringe sales under SB41 in Fresno and Kern Counties. In the absence of legislation requiring mandatory syringe sales, interventions should be developed to increase knowledge of the law and frame addiction as a medical condition, with a special focus on independent pharmacies. Informational interventions should stress the need to eliminate log book documentation requirements, which may serve as a barrier to IDU purchase.

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.
