Law Enforcement and Community Provision of Fentanyl Test Strips to People Who Use Drugs for Engagement and Referral to Services.

Use of fentanyl test strips (FTS) to test illicit drugs has been shown to be an effective harm-reduction tool for raising awareness of fentanyl risks, increased self-efficacy to prevent overdose, and safer use behavior changes. From March to June 2020, a total of 6 Massachusetts municipal police departments piloted FTS kit distribution during post-overdose outreach visits, community outreach, and related programming. The Police Assisted Addiction and Recovery Initiative developed the kits, trained departments, and oversaw implementation. The pilot evaluation involved site observations, process measures, and interviews with staff and kit recipients. For every kit distributed, there was approximately 1 health or support service or referral provided; 320 kits were distributed. Key themes from interviews were conceptualizing FTS as a tool, collaborations, and adaptations. Police departments that partnered with community programs amplified project reach. FTS distribution is a simple yet powerful tool that community providers and police can offer alongside linkage to care services and engagement with people who use drugs and their family and friends.

Examining the implementation of police-assisted referral programs for substance use disorder services in Massachusetts.

BACKGROUND: In response to the dramatic increase in opioid overdose deaths in recent years, police departments and community partners across the United States have begun to implement programs focused on connecting individuals to substance use disorder services. We examined the implementation of police-assisted referral programs from the perspectives of different team members to understand the key components of these programs and strategies used to implement them. METHODS: Qualitative research methods were used to examine the implementation of police-assisted referral programs in five Massachusetts communities between June 2019 and March 2020. Focus groups and interviews were conducted with 33 individuals, including 5 police chiefs, 12 police officers, 6 outreach workers, 4 community-based organization (CBO) directors, 2 interns, 1 clinician, 1 program manager, 1 religious representative, and 1 prevention specialist. RESULTS: Five key themes emerged regarding the implementation of police-assisted referral programs across the communities: 1) program development was an ongoing process; 2) partnerships between police departments and community stakeholders were essential for starting and sustaining a program; 3) high-level leadership influenced program priorities and facilitated implementation; 4) program success was defined in multiple ways; and 5) programs contributed to shifts in beliefs about substance use and addiction among police officers. CONCLUSIONS: Police-assisted referral programs in Massachusetts have adopted a variety of models of service delivery, evolving from post-overdose outreach and walk-in models to more complex hybrid forms. Implementation was facilitated by the support of departmental leadership, particularly the police chief, and the development of key partnerships across institutional boundaries. Communities continue to develop their programs to incorporate additional components, such as new mechanisms of outreach, harm reduction services, and long-term engagement activities. Further evaluation of these programs is needed to understand how each of these unique components may influence a program's impact on future overdoses, entry to treatment, and long-term recovery.

Characteristics of post-overdose public health-public safety outreach in Massachusetts.

BACKGROUND: As a response to mounting overdose fatalities, cross-agency outreach efforts have emerged to reduce future risk among overdose survivors. We aimed to characterize such programs in Massachusetts, with focus on team composition, approach, services provided, and funding. METHODS: We conducted a two-phase cross-sectional survey of public health and safety providers in Massachusetts. Providers in all 351 municipalities received a screening survey. Those with programs received a second, detailed survey. We analyzed responses using descriptive statistics. RESULTS: As of July 2019, 44 % (156/351) of Massachusetts municipalities reported post-overdose outreach programs, with 75 % (104/138) formed between 2016-2019. Teams conducted home-based outreach 1-3 days following overdose events. Police departments typically supplied location information on overdose events (99 %, 136/138) and commonly participated in outreach visits (86 %, 118/138) alongside public health personnel, usually from community-based organizations. Teams provided or made referrals to services including inpatient addiction treatment, recovery support, outpatient medication, overdose prevention education, and naloxone. Some programs deployed law enforcement tools, including pre-visit warrant queries (57 %, 79/138), which occasionally led to arrest (11 %, 9/79). Many programs (81 %, 112/138) assisted families with involuntary commitment to treatment - although this was usually considered an option of last resort. Most programs were grant-funded (76 %, 104/136) and engaged in cross-municipal collaboration (94 %, 130/138). CONCLUSIONS: Post-overdose outreach programs have expanded, typically as collaborations between police and public health. Further research is needed to better understand the implications of involving police and to determine best practices for increasing engagement in treatment and harm reduction services and reduce subsequent overdose.

Interfacial free energy of a hard-sphere fluid in contact with curved hard surfaces.

Using molecular-dynamics simulation, we have calculated the interfacial free energy γ between a hard-sphere fluid and hard spherical and cylindrical colloidal particles, as functions of the particle radius R and the fluid packing fraction η=ρσ(3)/6, where ρ and σ are the number density and hard-sphere diameter, respectively. These results verify that Hadwiger's theorem from integral geometry, which predicts that γ for a fluid at a surface, with certain restrictions, should be a linear combination of the average mean and Gaussian surface curvatures, is valid within the precision of the calculation for spherical and cylindrical surfaces up to η ≈ 0.42. In addition, earlier results for γ for this system [Bryk et al., Phys. Rev. E 68, 031602 (2003)] using a geometrically based classical density functional theory are in excellent agreement with the current simulation results for packing fractions in the range where Hadwiger's theorem is valid. However, above η ≈ 0.42, γ(R) shows significant deviations from the Hadwiger form indicating limitations to its use for high-density hard-sphere fluids. Using the results of this study together with Hadwiger's theorem allows one, in principle, to determine γ for any sufficiently smooth surface immersed in a hard-sphere fluid.
