We queried survey participants regarding their perspectives on harm reduction philosophies and counseling practices. Immunizations for tetanus were also uncommon, with only 36% of ID physician respondents routinely including this as part of standard care for PWID (Figure 1). When asked to consider what practice patterns form their standard care and counseling for PWID, ID physicians almost universally reported screening for HIV (98%) but were less likely to offer screening for other STIs, such as syphilis or gonorrhea (63%). As one respondent commented, “Management of OUD is critical in caring for our patients. Among those who reported having an X-waiver, even fewer (15 of 45 33.3%, or 4% of the total sample) reported actively prescribing buprenorphine to patients. Multiple respondents included additional comments in their surveys regarding the need for addiction medicine services when caring for PWID.

For policymakers, this review relays evidence from a growing body of literature demonstrating the effectiveness of SIFs in reducing overdose mortality and frequency, as well as improving access to addiction treatment. Both Gaddis et al.33 and Milloy and colleagues44 assessed the association between frequent use of the Vancouver SIF and access to care, finding a significant and favorable association with on-site detoxification services and null association with reporting being “unable” to access addiction treatment services, respectively. Finally, Kerr et al.34 using a before–after study design (rather than cross-sectional), identified a null change in community injection drug use and binge drug use in the year before and after the opening of the Vancouver SIF.

By reducing needle sharing, these strategies play a crucial role in disease control, helping to prevent the transmission of HIV, hepatitis C, and other blood-borne diseases.
However, 1 study found that an accelerated vaccination schedule (0, 1, and 2 months) offered through SSPs, with the initial vaccination dose given at screening, could improve completion rates .
Of the 22 included studies.28,29,31,33–36,39–49,51,53–55 8 studies39–41,46,48,49,51,54 had good quality of execution (1 or no limitation); the other 14 had fair quality of execution (2–4 limitations).
Critics argue that these sites send a message of societal surrender and that public funds would be better spent on prevention and abstinence-based treatment programs that aim to stop drug use entirely.
Stoltz and colleagues49 and Wood et al.53 were both prospective cohort studies analyzed in a cross-sectional manner, and Folch and colleagues31 was a cross-sectional study.

Thus, knowledge gaps related to clinical training, or generational differences in perceived role of the consultant, might represent additional barriers to both prescribing MOUD and counseling on harm reduction. Adding addiction management to traditional ID care likely presents an opportunity cost to the ID physician, who may feel pulled away from other critical work. One way ID physicians can fill this gap is by prescribing MOUD to PWID with infectious complications of injection opioid use. Recognizing these limitations, there has been a growing call for ID physicians to fill this gap for patients with infectious complications of IDU .

We attempted to evaluate the harm reduction counseling that infectious diseases physicians provide to PWID presenting with infections. Lastly, to further expand treatment access and reduce harm, ID clinicians should offer naloxone and become waivered to initiate buprenorphine for those interested in this treatment pathway. Methadone access is restricted due to prescribing limitations for OUD outside of a certified opioid treatment program, which preclude low-threshold access from an ID setting. Despite this, methadone and buprenorphine remain underutilized given significant treatment access limitations .

Review authors used standard systematic review methods outlined by the Community Guide.23,24 This systematic review was not registered and the protocol was not previously published. This is the first review, to review authors’ knowledge, that utilizes the Community Guide systematic review methods,23,24 which form the basis for findings of the U.S. One well-conducted review by Potier et al.22 examined SIF literature (database inception–January 2014). The original analysis plan for this review included quantitative synthesis methods, which benefit from a narrower, more-homogenous scope. Caulkins and colleagues20 looked at “higher-quality” literature (i.e., quasi-experiments, modeling studies) of SCFs, framing conclusions in the perspective of various decision makers (e.g., politicians, academics). Quantitative synthesis was not conducted given inconsistent outcome measurement across studies.

Access to Subspecialty Addiction Medicine Care and MOUD

Our community distribution plans need to continue to identify ways to get naloxone into the hands of individuals most at risk of overdose, who are also the individuals most likely to save someone’s life. Sometimes when people hear the term “harm reduction” they only think of naloxone or syringe service programs, which are specific harm reduction services. Rates of transmission of HIV were exceedingly high, and we knew that it could be transmitted through sharing injection equipment, which people still couldn’t access. Past negative experiences in health care make people very hesitant to go back. Finally, I have heard countless stories from my own patients about how terribly they have been treated in a variety of healthcare environments. For example, if you’re in a community where very few people inject substances, it’s still important to have access to syringes.

The estimated lifetime cost of medical care for one person living with HIV is approximately $510,000. This service significantly reduces contaminated needles discarded in public spaces like parks, playgrounds, and sidewalks, protecting the public and first responders from accidental needlestick injuries. Nearly three decades of research consistently show that comprehensive SSPs do not increase illegal drug use or crime. One persistent concern is that SSPs will increase crime and public disorder. Beyond distribution, they provide critical education on recognizing overdose signs, responding properly, and administering naloxone correctly.

Associated Data

So there are a lot of ways that stigma can make people afraid to step forward and ask for help. We also have a very punitive child protective services system in our country and there’s a lot of racial and ethnic discrimination in that system. This often makes people who use substances feel anxious about stepping forward and asking for help. Even if someone generally knows how much they can safely use, it can be very dangerous if they’re exposed to something they weren’t expecting.

WHAT IS HARM REDUCTION?

However, access could be readily expanded Reducing injection harm if ID clinicians obtained the DATA waiver and offered this as a treatment option to PWID alongside harm reduction during ID encounters. Other studies examined the behavioral changes among PWID after incorporating fentanyl test strips into their injection practices and found an association between positive change in risk behavior and receiving a confirmatory result on a fentanyl test 78, 79. Therefore, in the setting of ID, particular attention should be paid to not only incorporate harm reduction strategies to target injection technique as discussed above, but also to understand the underlying cause behind the infection. Preventative measures, such as supplying sterile equipment, educating on proper injection techniques, and providing postexposure prophylaxis (PEP) or pre-exposure prophylaxis (PrEP) to those who qualify can be taken to attenuate risk of infections.

The Impact of Safe Consumption Sites: Physical and Social Harm Reduction and Economic

By reducing needle sharing, these strategies play a crucial role in disease control, helping to prevent the transmission of HIV, hepatitis C, and other blood-borne diseases. The near-final results of this study were presented at the annual meeting of the American Public Health Association on October 27, 2020. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Angela R. Bazzi made a substantial contribution to the conception of the study and design of the study and to data interpretation; revised the article for important intellectual content; and read and approved the final version of the submitted manuscript. Sean R. Cahill made a substantial contribution to the conception of the study and design of the study and to data interpretation; revised the article for important intellectual content; and read and approved the final version of the submitted manuscript.

Review authors deemed four studies to be of greatest suitability of study design, with one of these studies (Wood and colleagues54) rated good quality of execution and the rest (Lloyd-Smith et al.,39 DeBeck and colleagues,29 and Kimber et al.36) rated fair.
One respondent commented that it is “difficult, if not impossible in the absence of addiction services to get very far,” while another responded, “we need better resources for treatment of the primary problem.” This was a common theme repeated in many of the comments.
First, EIN is a convenience sample of physicians and overrepresents academic medical centers and larger hospitals; thus, our results may be less generalizable to other ID physicians at smaller community hospitals.
We are also seeing some newer programs in the community like drug-checking services that allow people to test their substance and have a better sense of what is in it before they use it.
Studies in Vancouver have shown that SIF users reported less frequent reuse of syringes, and in 1 study, 57% of clients entered MOUD treatment programs.49,50 SIFs can also facilitate referrals to the hospital for earlier intervention.41,42

Decrease public injecting and increase public safety

In fact, several included studies in this review documented decreases in crime following the opening of SIFs. These outcomes were observed with no increase in crime and drug use–related public nuisance. The goal with this systematic review is to inform debates between local municipalities considering implementing SIFs7–9 and the U.S. federal government, which as of this writing, still considers such harm reduction interventions illegal under federal law.10,11 Finally, no effectiveness studies in the bridge search assessed how SIFs are responding to emerging trends in the opioid overdose epidemic. This likely reflects a historical, systemic withholding of funding and limited governmental support for harm reduction interventions.57,58 It also reflects the reality that SIFs are first and foremost community responses to crises; structuring ideal research conditions is, rightly, not their priority.

So we worked to obtain a grant that allows us to see people regardless of their ability to pay, and our clinic offers walk-in services. Much of the impetus for opening the clinic was knowing that it’s difficult for patients and families to find evidence-based, patient-centered services. In the community, the most common services are things like naloxone distribution and syringe service programs.

This finding is consistent with the included studies, none of which observed any fatal overdoses at their respective SIFs. McKnight et al.42 (a cross-sectional study) found that public injecting was significantly less likely when the SIF did not have a wait time (i.e., the SIF was readily available). The study authors found no meaningful or significant changes in drug trafficking and assaults/robbery, but observed significant declines in vehicle break-ins/theft. Review authors deemed the 5 remaining studies (Folch and colleagues,31 McKnight et al.,42 Wood and colleagues,51 Milloy et al.,45 and Wood and colleagues52) to be of least suitable study design and fair quality (with the exception of Wood et al.,51 which was deemed good quality). Over the same time period, there was no change in proportion of residents or business operators who had been offered drugs for purchase. Over 5 years, the study authors witnessed a significant decrease in the proportion of residents and business owners reporting witnessing public injecting or observing publicly discarded syringes.

As we look to the future of harm reduction, it’s clear that innovation, policy reform, and community engagement will be key drivers in expanding and enhancing the impact of these crucial strategies. These examples demonstrate that with adequate support and a focus on evidence-based practices, harm reduction strategies can lead to substantial health and social benefits. The effectiveness of SIS in improving public health and safety, while controversial to some, is supported by a substantial body of evidence. The significance of harm reduction in the realm of injection drug use cannot be overstated. This approach is not about encouraging drug use; instead, it’s about recognizing that drug use exists and choosing to prioritize health and safety over moral or legal judgments.

In addition, SCS services lead to greater uptake of addiction and other treatment resources, retain people in care, and expand medical services 6, 7. In a study of risk behavior among 1082 PWID at an SCS, 75% reported positive changes in injection behaviors, such as fewer rushed injections, fewer shared syringes, and a greater likelihood of using sterile supplies as a direct result of the services and counseling provided . However, this public health crisis is not irreparable—clinicians across all specialty settings can take measures to better mitigate this converging epidemic by incorporating harm reduction strategies, and ID specialists are uniquely positioned to promote these measures . Remember, every step taken in the realm of harm reduction is a step towards a healthier, safer community. By prioritizing harm reduction strategies, we not only pave the way for meaningful recovery but also protect the health and well-being of the community at large.

Wood and colleagues51 in 2004 examined drug use–related public nuisance measures in the weeks before and after the Vancouver SIF opened, finding significant reductions in public injection, publicly discarded syringes, and injection-related litter after the SIF opened. Seven studies31,42,45–47,51,52 reported outcomes relevant to crime and drug use–related public nuisance. Folch et al.31 found frequent SIF users in Spain had around twice the odds of accessing addiction treatment services in the previous 6 months as compared with less frequent SIF attendees. They found that frequent SIF use increased the rate of accessing treatment significantly in the study period by anywhere from 1.4 to 1.7 times, as compared with less frequent or nonusers. Wood and colleagues,54 DeBeck et al.,29 and Kimber and colleagues36 each calculated hazard ratios for the association between frequency of SIF attendance and access to addiction treatment or detoxification services.

My impression is that in recent years more medical, nursing, and other health professional schools have included substance use disorder education. We formally and informally ask patients if there are other things they wish we would offer. Our goal is to ensure that patients feel as comfortable as possible. We have a peer support specialist, a nurse care coordinator, medical assistant, and physician assistant on our team, and we meet regularly to talk about service delivery. It drives people away if they call and don’t get the right information or show up and don’t feel welcomed at the front desk. We also had to make sure everyone felt comfortable working with people who use substances.

Overdose Prevention Centers: The Next Step

The muscle tissue has a rich blood supply, allowing the drug to be absorbed into the bloodstream gradually compared to IV injections. Enter the philosophy of harm reduction, a beacon of pragmatism in the stormy debate over drug use and policy. In cities and towns around the world, countless individuals, much like Alex, engage in unsafe injection practices, a decision often made out of necessity rather than choice. Despite his efforts to be cautious, his lack of access to clean needles and a safe environment leaves him vulnerable, a reality faced by millions globally.
