Street Medicine: Creating a “Classroom Without Walls” for Teaching Population Health

“Street Medicine” programs provide medical care to homeless populations outside of traditional healthcare institutions, literally on the street and in transitional settings where unsheltered homeless people live. Such programs are emerging around the world often based at medical schools and primary care residency programs, and can provide ideal frameworks for twenty-first century “Classrooms Without Walls” aimed at improving Population Health. We provide a 12-step blueprint for creating a Street Medicine program in the context of a medical teaching institution.

Introduction

The evolution of Street Medicine

In 1992, Jim Withers, a faculty attending physician at the University of Pittsburgh Medical Center Mercy Hospital Internal Medicine Residency Program, dressed like a homeless person and, with a backpack filled with medicine, began clandestinely providing free healthcare on the streets at night for the unsheltered in his community [1]. What began as one doctor’s mission to create a “Classroom of the Streets” to teach about caring for excluded people, has grown over the last 25 years into the Street Medicine Institute (SMI) and movement (www.streetmedicine.org). Through the Street Medicine Institute’s annual international symposium, the movement has developed global reach. Based on information from the SMI website as well as anecdotal reports, Street Medicine colleagues on every continent are innovating and defining best practices, in partnership with a wide range of brick and mortar settings from academic centers to rural health clinics, all geared towards serving the unsheltered.

As the Street Medicine movement has grown, so has learner interest, as evidenced by the many clubs and programs that have popped up in affiliation with various medical institutions around the world. Despite the anecdotal growth in learner interest in homelessness and street medicine, its true extent has yet to be formally studied. It is important to distinguish between educational initiatives about homelessness (sometimes done via panels, didactics, speaker series, and electives) and the practice of street medicine—where medical care is provided on the street and in transitional settings where unsheltered homeless people live: under bridges and overpasses, in parks, alleys, and on street corners.

Street Medicine programs are often started by inspired learners who engage faculty sponsors, put on backpacks filled with medical supplies, and go out to homeless populations with the guidance of the SMI. Dr. Jim Withers describes these practices as “level one programs” or the "Robin Hood stage” in which there is minimal programmatic infrastructure, but a high level of commitment to the philosophy of social justice and health care as a human right.

While the impulse to respond rapidly to the health crisis of homelessness is laudable, creating a successful and sustainable Street Medicine program is challenging. Street Medicine practices involve many of the same challenges encountered with creating any new clinical service including accessibility, continuity, liability, continuous quality improvement, maintaining standards of care and avoiding negative unintended consequences. Furthermore, homeless populations are medically complex, transitory, and live in unpredictable and, sometimes, inaccessible, settings. Homelessness is tightly linked with barriers to care, co-morbidity with substance abuse and mental illness, as well as poor health outcomes overall, a shortened lifespan and increased mortality [2–6].

Street Medicine programs provide rich environments for teaching and studying health equity, and for exploring improvement in population health measures and practices [7]. These “Classrooms Without Walls” are clinically, philosophically, ethically, and pedagogically aligned with the depth and scope of primary care. We believe that Family Medicine, and other primary care clinical practices, are the ideal educational homes for such initiatives due to their broad scope which includes Behavioral Health, and their emphasis on Population Health and community oriented primary care [8].

Discussion

At the moment, there are no standardized, peer-reviewed published best-practices or approaches for starting a Street Medicine program.

Herein, we describe a model for developing a Street Medicine program that combines family medicine and population health concepts.

Define educational competencies

Inherent in its mission, identity, and name, Street Medicine requires skills that go beyond what is routinely taught in undergraduate or graduate medical education. With its atypical clinical setting and complex patient population, the skills and competencies most aligned with Street Medicine could be borrowed from other fields where medicine is delivered in low resource settings, with underserved or marginalized patient populations and in the field or under harsh conditions. For example, educators may review and adapt the skills and competencies most commonly suggested for Global Health education [9, 10].

Furthermore, learners must possess knowledge anchored in a deep appreciation for the impact of the social determinants of health [11] and the political determinants of health [12, 13] on the lives of homeless patients, and an understanding of the enormous disease burden [3] experienced by this population. Attitudes should be tied to exploration of themes related to health equity [14] and social justice [15]. Clinical skills can be linked with existing undergraduate and graduate recommendations, involving communication and interpersonal skills, professionalism and ethics, system-based issues (including healthcare financing and utilization), among others.

Some programs have been working on developing general guidelines and resources [16–19], especially related to homelessness in general. Related competencies include Adverse Childhood Experiences [20], trauma informed care [21], harm reduction, principles of homeless outreach [16], and de-escalation techniques [22]. In addition, skill development should focus on substance abuse, and mental and behavioral health, as these issues are interlinked with each other and with homelessness both as risk factors and as chronic health problems. Methods for ensuring competency in continuous quality improvement should be integrated throughout the curriculum.

Develop a Curriculum

Once competencies have been defined, the curriculum can be designed to meet these requirements. Street Medicine provides a “Classroom Without Walls” and as such the goal is to offer experiential learning to health profession students and residents, out on the streets working directly with individuals who are unsheltered. However, any curriculum must involve preparation before going out to the streets and include didactic teaching to provide learners with contextual background. Pedagogically, didactics can be delivered via small group discussions and case-studies [18] and with “bedside teaching” during street rounds.

Ultimately, Street Medicine is about engaging with this population where it lives. Various experiential electives for the provision of health care for homeless populations have been described in the literature, in various settings, primarily at fixed location homeless shelters and specialized clinics [23], but not necessarily on the street or in transitory settings. A program for medical and pharmacy students in New Mexico where learners provided care to homeless individuals in shelters as well as conducted street outreach was perceived by the learners “uniformly” as “transformative” [16]. One leader, Dr. Aurinés Torres-Sánchez, describes the Street Classroom as an ideal environment for training medical learners in the values and practices of social justice and equity [24].

Create evaluation and assessment protocols

Measurement and reporting outcomes will be important for population health data, epidemiology, and continuous quality improvement as well as for medical education scholarship. For learners, we can assess knowledge acquisition via exams and surveys as well as from direct observation of clinical encounters. Attitudinal changes can be assessed via surveys [25, 26] or via instruments such as the Health Professional Attitudes Toward the Homeless Inventory (HPATHI) [27]. Some have looked for associations between homeless medicine programs and various professionalism measures, showing improvements in empathy and decreases in negative stereotypes [19, 28].

Additional learner-associated measurements can include changes in wellness metrics and burnout scores, an emerging field of research in medical education and in primary care. Previous studies have demonstrated that feeling engaged leads to increased satisfaction at work [29–31]. We can hypothesize that Street Medicine may improve learner engagement, and thus wellness, but needs further study. Table ​ Table1 1 includes some suggestions for learner evaluation and assessment modalities.

Patient-oriented outcomes must be included so that we can learn what interventions work best for this population [32]. One study assessing the quality and “best practices” of several Street Medicine programs recommended two patient-centered outcome measures: patient engagement and patients' subjective assessment of their well-being [33].

Other metrics can assess the population health and downstream benefits of Street Medicine, including changes in acute care vs. primary care utilization; hospital Length of Stay; housing status; morbidity and mortality; and improvements in social and political determinants of health.

Acquire sustainable sources of funding

As with any new educational program, the business case must be made to the sponsoring institution so that the program can be sustainably funded. International data show that complex populations, including the homeless, comprise approximately 5% of the overall population and incur 50% of health care costs [34]. Homeless populations tend to be super-utilizers of acute systems of care [35–37], so a Street Medicine program, providing “hotspotting”, (medical outreach to super-utilizers), such as described by the Camden Coalition Hot-spotting Curriculum (www.camdenhealth.org/curriculumum, www.camdenhealth.org/curriculum), may be cost-saving, especially if linked with primary care. Some talking points may include that Street Medicine (a) may improve access to primary care, thus avoiding unnecessary utilization of acute care services (b) may overlap with Disaster medicine, thus improving the effectiveness and reach of disaster preparedness and response. Planners should use data from annual homeless surveys such as the, federally mandated Point in Time counts. Tracking of homeless populations is challenging and is done differently in different settings. There are several grant funded Street Medicine programs across the USA which the authors have learned about anecdotally. It would be beneficial to develop a tracking system of successful grants for Street Medicine programs in order to help guide future grant writing efforts. For example, in September 2019, a $ 1-million HRSA RCORP (Health Resources and Services Administration Rural Communities Opioid Response Program) grant written by one of the authors (Doohan) was awarded to Adventist Health Ukiah Valley hospital for a “Safe Haven Clinic” that includes Street Medicine, sobering, medical respite, and a pharmacy in one facility located proximal to the Emergency department.

Conduct needs assessment

A needs assessment determines best locations and times for street rounds, identifies interested stakeholders such as law enforcement and first responders, and seeks collaboration from partner agencies, including churches, inclement weather shelters, and sobering centers. The goal is to provide Street Medicine rounds on the same day of week and at the same time, to enhance reliability. It may be preferable to conduct street medicine rounds at night when volunteer clinicians are available and homeless populations have settled and may be more open for “house calls”.

One key concept is to “follow the food” and set up a mobile clinic alongside a program that provides free meals. Such places can serve as a starting point for street rounds, and then expand to a route leading to/from that spot that includes places like sobering centers [38].

Programs should conduct a safety assessment of the area where rounds take place so that every precaution is taken to ensure that faculty, learners, and the people served are kept safe. This can be achieved by coordinating with local law enforcement, avoiding areas where criminal behavior has been known to occur, and meeting in well-lit and populated area. According to anecdotal reports from the Street Medicine Institute website, Street Medicine is a relatively safe practice, such that “thousands of street rounds have been conducted throughout the world without incident”.

Define organizational structure

Because Street Medicine programs are complex systems of healthcare delivery in atypical clinical settings, it is important to have clear organizational structures and chains of command. It can be very helpful to use a system such as the Incident Command Structure (https://www.fema.gov/incident-command-system-resources) developed by the US government for disaster preparedness and response. A typical team may include an Incident Commander (the lead faculty physician/medical director) and 4 team leaders: Finance; Logistics (medical packs, transportation, volunteer coordination); Operations; and Planning. Not all individuals in the program are involved in the operations on the street. In fact most of the work is actually done behind the scenes and not on the front lines of care provision.

Partner with local agencies

In addition to getting buy-in from a medical education institution, teaching hospital, or residency program, it is crucial to develop partnerships with local organizations or healthcare institutions that serve the homeless population, have insight about their needs and behaviors, and could contribute to the provision of social services and self-care capacity. Partners can include the local police, department of health, Emergency Medical Systems, local emergency departments, homeless shelters, food pantries, substance use disorder treatment a services, and housing authorities. These partnerships can foster and enhance care coordination and provision of multiple other services via regularly scheduled meetings. Having an MOU (Memorandum of Understanding) between the partner agencies and the Street Medicine program is advisable and typically requires institutional legal review.

Create policies, procedures, and protocols

Commonly, Street Medicine programs are quick to respond to the call to service without creating policies and procedures first. Indeed, many policies and procedures will develop and be fine-tuned over time, but basic policies and procedures must be established from the start and reviewed by legal counsel and/or risk management according to the standards of the institutions involved. Suggested protocols include: principles of homeless outreach, response to violence, interacting with the media, and “follow-ups”. Referral procedures must be established related to calling an ambulance, sending a patient by non-urgent transport to the hospital Emergency Department, facilitating timely access to continuity primary care, and communicating referrals and “warm hand offs” to partners or other agencies [39].

From the medico-legal and ethics perspective it is important to have written policies about the different roles and responsibilities of the various team members, especially the learners, to avoid anyone working beyond their scope of practice or above their level of education or expertise. It is essential to confirm how medical malpractice insurance will be provided to the team or to volunteer faculty from organizations outside the teaching institution.

Establish electronic medical record and data tracking system

A Street Medicine program must be held to the same standards as any medical clinic, and that includes record keeping and maintaining HIPPA compliance despite the public environment where Street Medicine clinics occur. There are affordable, cloud based mobile Electronic Health Records that can be customized such as OpenMRS. Data can be integrated with the home-institution to improve care coordination, for Quality Improvement projects and outcome reporting. Strategies should be explored for ethical data sharing with partner agencies to improve the health of the population served [40].

Determine medication formulary and stock medical packs

In the model described herein, the scope of practice is urgent care. All drugs, tools, and supplies are carried by team members in backpacks. Three packs are typically needed: a clinician (“prescriber”) pack, a nursing pack, and a wound care pack. Table ​ Table2 2 includes a description of tools, equipment, and medications included in the packs. Consider conducting periodic vaccine clinics and health screenings for chronic and communicable diseases such as HIV, Tuberculosis, Hepatitis C, and diabetes and adjust the supplies accordingly. Collaborate with the pharmacy department of the sponsoring institution to determine protocols and mechanisms for dispensing free medications, storage, tracking, and removal of expired drugs. Do not carry “high street value” medications in the packs such as narcotics and benzodiazepines.
