Homelessness is Traumatizing

Homelessness and Resilience

• Few homeless individuals are isolated and alone

– Street culture community may be essential for survival even if not “healthy”

• Strengths based approaches support resilience and coping

– Specific daily life skills training

– Spiritual support

common co‐occurring challenges in homeless

• Cognitive impairments– > 50% of HL with SUD with significant impairment– Use several forms of communication – Keep It Simple

• Mental Health Disorders– Trauma – Get practical about trauma informed approach– Psychiatric Disorders– Substance Use Disorders– Poorly recognized conditions– Complex trauma/Autism Spectrum/ADHD

Adaptations to Practice

• Ask about Homelessness and housing stability– “What is your Living Situation?”– “Will you be able to stay there? Is that safe?”

• Assess Homeless Street Smarts and Survival Skills– How will current illness change persons ability to

survive?– How can we scaffold persons success when back in the

community

Shelter

Street/Vehicle /Encampment

• Most people experiencing homelessness will remain homeless for the foreseeable future

• Use Bio‐Psycho‐Social‐Spiritual approach– Multi‐disciplinary, integrated, whole person

• Explore barriers to care specific to each patient• Develop action plan to overcome specific barriers• What is back up plan? What is back up plan to the back up plan?

CSAM State of the Art Conference | August 30 – September 1, 2018 | San Francisco

Barriers to Treatment: Patient challenges– No insurance/medi‐cal

inactive– No ID– No phone– Getting to appointments on 

time very difficult– Can’t / won’t leave stuff / 

pets– Can’t / won’t leave partner– Will lose everything by 

entering treatment– 86’d from clinics and services

– Can’t trust doctors– Feel ashamed due to 

appearance, hygiene, chance of meeting other community members

– Warrants or other criminal justice complications

– Chaotic constant drug use– Acute medical issues

– “No one cares about my health”

Barriers to Treatment:Provider Perception of Patients

– “They just don’t care about their health”

– They don’t belong in the hospital but they don’t belong on the street

– Frequent lost or stolen medication

– If we are overly kind to them they’ll keep coming back

– Poor previous track record of adherence to medical plans

– Miss appointments– Safety risk– Poor hygiene– Disturbing to other 

patients– Time consuming and 

manipulative

Selected Adaptations

• No Insurance: 

– Formulary of medications free on site or arrangements with a local pharmacy

– Exceptions to eligibility criteria to assure people get care

– Assistance to get on Medicaid (CA medi‐cal)

• benefits navigator In locations where HL are – Shelters, clinics, 

Adaptations to Practice

• Appointments are the enemy of people experiencing homelessness– Open access – more than just drop in– Offer “meaningful waiting”– CAYA ‐ “Come as you are”

• Opportunities to practice in unconventional sites– Deliver services where people are– Respite, shelter, navigation center, needle exchange, 

residential programs, etc

CSAM State of the Art Conference | August 30 – September 1, 2018 | San Francisco

Selected Adaptations

• Trauma histories including bad experience in health care and treatment– Trauma informed approach– Kind human interaction from first moments of encounter

• Cognitive impairments:– Multiple forms of communication– Outreach, frequent visits

Selected Adaptations• Victimization: Lost, Stolen, Destroyed Medications

– Short Rx duration –small Rx with refills rather than 1 month supply

– Strategies for safe storage– Shelters may offer daily dispensed

• Chaotic substance use and chaotic lives– Mutual goal setting– Welcome people back who are intermittent with follow up– Creative approaches to intensifying treatment

Selected Adaptations

• Usual healthcare quality indicators may not be relevant for homeless populations

– Review indicators and eliminate or adapt them

– Add new indicators based on risks in population

Selected Adaptations

• Patients leaving “Against Medical Advice”– Establish this as an “unusual occurrence” or critical marker to initiate quality improvement

– The reason is virtually never “don’t care about my health”

– Ask patients experiencing homelessness as a matter of course early in hospitalization whether there is anything that would interfere with their staying in the hospital until their condition is stabilized

Selected Adaptations

• Immersion in substance using community– Naloxone for everybody

– Alternatives to abstinence from all drug use as treatment goal

– Retention in care as primary desirable outcome

– Improved functioning and safety as desirable outcomes

Selected Adaptations

• Respite Care

• Street Medicine

• Shelter Health

• Formal and informal collaborations

• Ambulatory Intensive Care

Selected AdaptationsAdherence Assistance

• Recognize unique challenges and opportunities related to homelessness

• Ask about patient’s typical daily activities• Use patients’ already established habits

– E.g. when is there time to take meds, patterns of drug use,

• Consider patients limited choices when offering dietary / nutritional advice 

Selected AdaptationsAdherence Assistance

• Diuretics or meds causing diarrhea may be major challenges when there are no bathrooms– May need to change usual advice of no diuretics at night

• Sedating meds may be problem for individuals who need to maintain vigilance

• Pay attention to interactions with street drugs

Top Ten Pearls

1. Lice Are Not Scary– Body lice: shower and fresh clothes – that’s all– Head lice: clip hair to <1cm if possible, nitpick!

2. TB among homeless is way down– Always symptoms screen– Test and document TB clearance early

3. Bad Teeth Suck– Dental care is scary but can be life changing

Top Ten Pearls4. Appointments are the enemy5. Understand the exact details of a persons daily life and 

activities before attempting to make interventions and give advice– Staff involved in care and discharge planning need to see 

shelters, navigation centers, drop in centers, etc

6. Trauma leads to disconnection of mind and body and will create challenges in providing care

7. Working with people experiencing homelessness will change you– Incorporate self‐care for vicarious trauma programmatically and 

personally

Top Ten Pearls8. Create a trauma informed space

– Do a walk through with a consumer or imagine you’ve just been traumatized and are walking in.

9. Train all staff on homeless related issues– Professional staff can have the best intentions to treat patients with dignity and respect but have poor outcome if other staff have stigmatized or shamed a patient

10. Celebrate small incremental positive outcome– Low Expectations High Hopes

Bio‐Psycho‐Social‐Spiritual care for people experiencing homelessness

• Consider unusual infections – lice borne, flea borne, rat borne, conditions of neglect– Bartonella, leptospirosis, deep tissue infections

• Medical effects of methamphetamine use are underestimated– High rates heart failure, neurological conditions, infections

• Methadone and buprenorphine for opioid use disorder are our most effective treatments for any substance use disorders– Project Shout  https://www.projectshout.org/

Bio‐Psycho‐Social‐Spiritual care for people experiencing homelessness

• Violence and victimization are daily occurrences on the street, they are the constant accompaniment of the homeless person.

• Hospitalization (medical or psychiatric) is a good time to establish an accurate psychiatric diagnosis and initiate treatment 

Bio‐Psycho‐Social‐Spiritual care for people experiencing homelessness

• Priorities such as obtaining food and shelter may be placed above medical care.

• Homeless people are often blamed for a variety of social ills and exploited for political purposes

• Getting beyond compassion fatigue– Homeless consult service (social medicine service)

– Empower staff to create ad‐hoc or informal multi‐disciplinary teams

Bio‐Psycho‐Social‐Spiritual care for people experiencing homelessness

• Widespread Depression, Addiction, and Other “Mental Illnesses” reflect something widespread wrong with our way of living

– materialism, consumerism, enormous wealth disparity, family and community disintegration, loss of meaning, loss of self value and worth

Bio‐Psycho‐Social‐Spiritual care for people experiencing homelessness

• Problem of Boredom and withdrawal from living on the edge– Homelessness and addiction are like a full time job

– Lack of a meaningful role in society is extremely destructive

• Authentic concern, engaged supportive listening, understanding of what it means to be homeless are key interventions

San Francisco 2019 Landscape• 18,000 registered as Homeless

– 4000+ psychotic disorder and severe SUD

• 300 – 1000 housing slots open per year• Effort to rationalize housing based on vulnerability

Interagency Prioritization Method

WHOLE PERSON CARE DELIVERABLES

ACCOMPLISHMENTS:

- HSH (Dept of Homelessness and Supportive Housing) completed over 6,000 Coordinated Entry assessments in FY1819 and prioritized 1,001

- DPH endorsed HSH’s Coordinated Entry prioritization methodology- HSH endorsed DPH’s ranking methodology to prioritize those with co-occurring histories of

psychoses diagnoses and substance use disorders

WORKS IN PROGRESS:

- Individuals with histories of psychoses under-represented in Coordinated Entry pools:- assessed, but not prioritized- not yet assessed

• Prioritization process is fair, equitable, and transparent

• Pathway is clear to necessary resources and services

• Response is trauma-informed, culturally-competent, and adaptableto the unique needs of individuals

• For clients and staff, process is hopeful and reinforces belief that positive change is possible

• Process is built and success is measured with a racial equity lens

• Success and accountability are shared across agencies

Policy Approach

• No single “problem of homelessness”

– Define problems before solving them

– Adopt housing as a human right

– Provide housing and services that are effective and acceptable and recognize long term need

– Collaborate within community

• Until we house those experience homeless:– Provide Realistic / practical solutions

• Problem: people urinating and defecating in street, spread of contagious diseases

• Solution: more accessible toilets and handwashing where homeless people are

• Problem: Homeless people congregating in streets and parks

• Solution: Create compelling places for people to be during the day (and night) other than streets and parks

Policy Approach

– Realistic / practical solutions• Problem: people drinking alcohol and using drugs in plain view of the public, high rate of overdose deaths

• Solution: Sobering / safer recovery centers, supervised consumption facilities

• Problem: Overuse of emergency and acute healthcare services by individuals experiencing homelessness

• Solution: Careful analysis and then targeted solutions– Example SF and other counties Whole Person Care initiatives
