Community Treatment Order (CTO)
• purpose: a community treatment order(CTO)orders a person suffering from a serious mental
disorder to receive treatment and supervision in the community.Based on a comprehensive plan
outlining medications, appointments, and other care believed necessary to allow the person to live in
the community (vs.in a psychiatric facility,where conditions are more restrictive)
• intended for those who:
due to their serious mental disorder, experience a pattern of admission to a psychiatric facility
where condition is usually stabilized
• after being released, these patients often stop treatment,leading to destabilization
• due to the destabilization of their condition, these patients usually require readmission to
hospital
if CTO violated (i.e.treatment not taken,does not comply with follow up),the physician can issue
a Form 47 which is an order for examination that allows the police to bring the patient to the
hospital for an examination (usually the patient is examined and the treatment will continue as
per theCTO)
• criteria for a physician to issue a CIO
patient with a prior history of psychiatric hospitalization (cumulative >30 d over >2
hospitalizations in the past 3 yr),or the person has been subject to a previousCTO in the past 3yr
a community treatment plan for the person has been made
examination by a physician within the previous 72 h before entering into theCTO plan
• ability of the person subject to theCTO to comply with it
consultation with a rights advisor and consent of the person or the person’
ssubstitute decision
maker
• CTOs are valid for 6 mo unless they are renewed or terminated at an earlier date such as
when the person or his/hersubstitute decision-maker withdraws consent to the community
treatment plan
• CTO processis consent-based and allstatutory protections governing informed consent apply
• the rights of a person subject to a CTO include
the right to a review by the Consent and Capacity Board with appeal to the courts each time a
CI'
O isissued or renewed
a mandatory'review by the Consent and Capacity Board every second time a CTO is renewed
the right to request a re-examination by the issuing physician to determine if the CTO isstill
necessary for the person to live in the community
the right to review findings of incapacity'to consent to treatment
provisionsfor rights advice
CTO Legislature
• Ontario passed CTO legislature
on December 1.2000 (known as
"Brian’
slaw")
. Similar CTOs have been implemented
in Saskatchewan (1995), Manitoba
(1997), and British Columbia (1999)

Landmark Psychiatry Clinical Trials
Trial Reference Results
Schizophrenia
CATIE Psychiatr Serv 2008;59(5):500-506 Title:What CATIE Found:Results From the Schizophrenia Trial
Purpose:Compare the effectiveness of a proxy first-generation antipsychotic (perphenazine) toseveral second-generation
antipsycholics.
Methods:1460 patients with chronic schizophrenia were randomly assigned in a double-blind study to receive one of
perphenazine,olanzapine,quetiapine.risperidone, or ziprasidone for up to 18 mo.
Results:Perphenazine did not differ significantly in overal effectiveness or benehts compared to the second-generation
antipsycholics.Perphenazine was the most cost-effective drug.Individual clinical circumstances impacted drug effectiveness.
Patients who have a poor response to an initial medication may tolerate and see greater effectiveness with a different medication.
Conclusions:First and second-generation antipsychotics did not differin overall effectiveness.Patient factors must be considered
when prescribing antipsychotic medications.
Major Depressive Oisorder
TRANSFORMS Am J Psychiatry 2019,176|6):428-438 Title: Efficacy and Safety of Flexibly Dosed Esketamine Nasal Spray Combined with a Newly Initiated Oral Antidepressant in
Treatment-Resistant Depression:A Randomized Double-Blind Active-Controlled Study
Purpose:Evaluate the efficacy and safety of flexibly dosed esketamine nasal spray for patients with treatment-resistant
depression.
Methods:Patients with treatment-resistant depression vrere randomly assigned treatment of esketamine nasal spray witha
newly initiated antidepressant or a placebo nasal spray with a newly initiated antidepressant.
Results:197 participants completed the study. Patients receiving the esketamine nasal spray plus antidepressant treatment
demonstrated a change in Montgomery-Asberg Depression Rating Scale score that was signifrcantly greater than placebo nasal
spray plus antidepressant atd 28. Clinically meaningful improvements were found in the esketamine group earlier in the study
timeline.
Conclusions:Esketamine nasal spray was a safe,rapid-acting, and efficacious therapy for treatment-resistant depression.

Historical
G
Perspective
Over the last century,the focus of pubic
health has evolved:
. Infectious diseases:a prominent
issue in low- and middle-income
countries and higher income
countries aike:includes emergent
dseases caused by unfamiliar
or new pathogens,inefficient or
inappropriate antibiotic use.travel
global wanning (eg.HV.drugresistant TB.C0V1D-19).and the
manufactured conditions of crisis
and/or routineconditions of poverty
imposed on Indigenous.Black,and
other communities of colour
• Chronic diseases:have increased
morbidity and mortality (e g.heart
disease and cancer due to risk
factors and'or exposures) and
disproportionatety affect Indigenous
populations throughout the world
• Social determinants of health:
driven by a growing body of evidence
since the1980sthat universal
accessto health care services did
not ameliorate health inequalities,
and thatsignificant improvements
in health could only be achieved
by going '

Public Health in Canada
The public health service in Canada is composed of various agencies at the federal (Public Health Agency
of Canada), provincial (Public Health Ontario), and municipal/local levels (local public health units).
The organization of the public health system in each province varies widely and is usually separate from
the healthcare system.
Mission of the Public Health Agency of Canada (federal only):to promote and protect the health of
Canadiansthrough leadership, partnership, innovation, preparedness, and action in public health
•local public health units and services within regional health authorities(in most provinces except
Ontario, where local public health units are either autonomous or within local government) provide
programs and activities for health protection, promotion, and disease prevention at local and regional
levels
•catchment-area populations range widely (hundredsto millions), covering areas of 15-1.5 million km -
•the “core functions" of public health include six essential activities
The Association of Faculties of Medicine of Canada Public Health Educators' Network. AFMC Primer on Population Health[Internet).The organization of
health servicesin Canada;[cited 2006 Mar 25[. Available from https://phpriiner.afnic.ca/enl
1. health protection:measurestaken to address potential health risks at the population level
through regulation and advising government (e.g.safe water and food supply)
2. health surveillance: monitoring and predicting health outcomes and determinants with
systematic,longitudinal data collection
3. disease and injury prevention:addressing infectious disease through preventive (e.g.
vaccination, droplet protection) and control (e.g. quarantine) measures;reduce morbidity
through lifestyle improvement
Example of a Municipal Health Unit
The Middlesex-London Health Unit
• Serves 450000 people living,
working,visiting,and studying in the
city of London and Middesex county
• 275 fulFtime staff indudingMOHs

etc
• Servicesindude infectious disease
control,ensuring environmental
health standards, health promotion,
and providing family health programs

4. population health assessment:studying and engaging with a community to understand their
needs and improve policies and services
5. health promotion: advocating for improved health through broad community and
government measures (e.g.policy, interventions,community organizations)
6. emergency preparedness and response: developing protocols and infrastructure for natural
(e.g.hurricane) and man-made (e.g. opioid crisis) disasters. In many types of health-related
disasters, public health leads the disaster response

Definitions olHealth
• Multidimensional definition ol health,
as defined by the WHO in1948:
"state ol complete physical,menial
and social well being and not merely
the absence ol disease or infirmity"
• WHO updated the definition (socioecological definition) of health In
1986:"The ability to Identify and to
realize aspirations,to satisfy needs,
and to change or cope with the
environment. Health is therefore
a resource for everyday life,not
the objective of living.Health is a
positive concept emphasizing social
and personal resources,as well as
physical capacities"(Ottawa Charter
for Health Promotion)
• Other definitions of health have since
been proposed that incorporate
other dimensions of health
• "Health is a social, economic,
and political issue and above all a
fundamental human right”- The
People's Charter for Health
• "Health is the continuous and
harmonious interaction and balance
between the physical,emotional,
spiritual,and mental/intellectual
realms" The National Aboriginal
Health Organization

Determinants of Health
• I 974: the Honourable Marc Lalonde, federal Minister of Health, publishes A New Perspective on the
Health of Canadians which outlines four factors that determine health: “human biology, environment,
lifestyle, and health care organizations.
"The idea of determinants of health has since been expanded
and refined to include many additional factors

build capacity to address poverty in their practice
and facilitate referral to evidence based community
intervention programs.
• cultural humility: an approach to health care based on humble acknowledgement of oneself as a
learner when it comes to understanding a person'
s experience, This is a life-long process of learning
and being self-reflexive
• culturalsafety:
developed by Ur. lrihapeti Ramsden, a Maori nurse scientist, in the 1980s and is “concerned with
the power relationships between nurses and those in their care. The recipients of nursing care are
empowered to decide what is culturally safe rather than complying passively with the authority of
nurses or other health professionals"
- Cancer Australia
“an approach that considers how social and historical contexts, as well asstructural and
interpersonal power imbalances,shape health and health care experiences. Practitioners are selfreflective/self-aware with regards to their position of power and the impact of this role in relation
to patients” - HeretoHelp British Columbia
• cultural awareness: an attitude that includes awareness about differences between cultures
• culturalsensitivity: an attitude that recognizes the differences between cultures and that these
differences are important to acknowledge in health care
• cultural competency: an approach that focuses on practitioners’attaining skills, knowledge, and
attitudesto work in more effective and respectful ways with Indigenous patients and people of
different cultures Ottawa Charier for Health Promotion
(1986)
• Health promotion: the process of
enabling people to increase control
over, and improve their health
• Some health promotion can be
achieved through clinical interactions
with patients,but most health
promotion is done at the population
level by public health professionals
and agencies through engaging
stakeholders,formulating policy, and
influencing upstream factors
• The Ottawa Charter is a framework
for thinking about health promotion
• The Ottawa Charter states that
governments and health care
providers should be involved in
a health promotion process that
includes:
1. Building healthy public policy
2. Creating supportive environments
3. Strengthening community action
4. Developing personal skills
5. Re-orienting health services
Groups Facing Systemic Barriers, Discrimination, and
Structural Violence
• certain groups are at greater risk for poorer health outcomes not due to their identity, but rather due
to systemic barriers, discrimination, and structural violence (e.g. harmful policies, historic, and
contemporary factors). The readers are strongly cautioned against pathologizing entire groups and
are encouraged to further read into the historical factors that have contributed to creating systemic
barriers which perpetuate inequities

Screening for Poverty
• poverty is not always apparent despite being widespread (20% of families in Ontario live in poverty)
• poverty is a risk factor for many chronic diseases, cancer, and mental illness
• women, Indigenous peoples, new immigrants, and LGBTQ+ are some of the groups at highest risk of
living in poverty
• primary healthcare providers should intervene,such as by asking the following two questions:
step 1: “Do you ever have difficulty making ends meet at the end of the month?”
for living below the poverty line,sensitivity 98% and specificity 40%
step 2: “Have you filled out and sent in your tax forms?"
tax returns are required for accessing many income security benefits like GST/HST credit,
working income tax benefits, property tax credits, child benefits, etc.

Colonization and Healthcare
Colonizers have perpetrated specific acts throughout Canadian history that have greatly impacted the
physical, mental, emotional, and spiritual health of Indigenous peoples. Physicians should therefore
be aware of the historical (and current) underpinnings of Indigenous health disparities, and the
way in which health care professionals, including physicians, have acted as agents of the colonial
agenda historically, which are discussed here, and their responsibility to redress previously damaged
healthcare relationships (seeEthical, Legal, and Organizational Medicine, Resources in Indigenous
Health, ELOM29). Despite institutionalized abuse and assimilation, Indigenous people have survived
remarkable injustice and have built resilience through traditional knowledge and practices.
Residential Schools (1870s-1996)
The residentialschool era is well-known for itslasting and damaging effects on many generations
of Indigenous people.Many Indigenousstudentssuffered from poor nutrition, hygiene, and living
conditions, as well as physical,sexual,and psychological abuse from teachers and othersin power.
The intent of residential schools to assimilate Indigenous people also led to spiritual harmsthrough
significant loss of traditional language and culture.Residential schoolsurvivors report poorer general
and self-rated health as well asincreased rates of chronic and infectious diseases, mental distress,
depression,substance use, and suicide. Importantly, many of these outcomes extend to subsequent
generations(i.e.intergenerational trauma).
The term “residentialschoolsyndrome” has been proposed to better characterize the traditional
DSM-V definition of post-traumatic stress disorder with additional criteria speci
schoolsurvivors,such as tendency to misuse alcohol and drugs(often at a young age), loss of cultural
knowledge, violent or angry outbursts, and difficulty parenting. Treatment approaches must take into
account a holistic viewof all these criteria,rather than simply focusing on one aspect,like substance
use,which often perpetuates negative stereotypes.
In Canada,many Indigenous healing
practices include drumming,singing,
smudging,herbalteas, sweat lodges,
and other ceremonies.Healthcare
providers are encouraged to
research and explore these options
as an additional therapeutic toolfor
Indigenous patients requesting them.
Not all Indigenous patients will request
such treatments and so perhaps first ask
patients. “What do I need to know about
you as a person to give you the best care
possible?”

The Truth and Reconciliation Commission (TRC) (2015) is a document jointly created by the Canadian
government and residential school survivors that preserves in writing the truth of residentialschools
PH8 Public Health and Preventive Medicine Toronto Notes 2023
and delineates recommendations for reconciliation. Many TRC recommendations pertain directly to
health and healthcare providers. Unfortunately,seven years later they remain recommendations and
have not become Calls to Action.
Nutrition Trials
Prom 1942 to 1952, nutritional scientists in conjunction with the Canadian government performed
unethical research on Indigenous people with tne aim of “studying the state of nutrition of the Indian.”
The lames Bay Survey is perhaps the most well
-known of these studies conducted on the Attawapiskat
and Rupert's House Cree First Nations, though many were conducted on residential school children
as well. One of the lead physician-scientists was Dr. Frederick iisdall (inventor of Pablum),former
president of the Canadian Paediatric Society and paediatrician at the Hospital for Sick Children in
Toronto, Ontario.Some unethical and arguably criminal acts committed by researchers were:
•lack of informed consent from parents or children
•Indigenous children were kept malnourished over a two-year period to establish a baseline
•one group of children received a flour mix not yet approved for sale that caused them to develop
anemia, contributing to greater morbidity and mortality in this group with no therapeutic
intervention
•in an effort to control as many factors as possible, dental care was denied to observe the progression of
dental cavities and gingivitis in the setting of malnutrition
Impact of Sustained Caloric Restriction on Residential School Survivors and Other
Generations
•sustained caloric restriction can cause height stunting, induce physiological changes to prioritize fat
over lean mass, and higher risk of developing type 2 diabetes
•stunting negatively impacts neurological, psychological,and immune systems
•due to sustained starvation, “the child’
s physiology is essentially ‘programmed’ by hunger to continue
the cycle of worsening effects, with their bodies displaying a rapid tendency for fat-mass accumulation
when nutritional resources become available”
•other generations are at risk of having a higher BM1 and developing obesity
Tuberculosis, Tuberculosis Sanatoriums, and “Indian Hospitals”
kuropean colonizers brought tuberculosis (TB) to Indigenous populations as early as the 1700s.
genous communities, particularly the Inuit, already had risk factors predisposing the spread of
TB. For example, there was malnutrition from food scarcity and overcrowding on federally mandated
reserves after forced relocation from traditional territories. From 1930-1940, death rates from TB
in Inuit populations were roughly 700 per 100000, among the highest ever recorded in a human
population. For comparison,TB was the tenth leading cause of death globally in 2016 at a crude death
rate of 17 per 100000, while ischemic heart disease was the first at 126 per 100000. This led the Canadian
government to forcibly relocate many Indigenous people to TB sanatoriums and “Indian hospitals,"
often hundreds of kilometres away.The average length ofstay at these institutions was 2.5 yr and many
patients never returned home.
hull
The TB health crisis persists today;in 2016, the average annual incidence rate of T
'
B among the Inuit in
Canada was roughly 296 times higher than Canadian-born non-lndigenous people.In March 2018, the
national representational organization for Inuit people in Canada, called Inuit Tapiriit Kanatami(1TK),
and the Government of Canada committed to reduce TB rates across Inuit communities by 50% by 2025
and to eliminate TB by 2030 in a project called the Inuit Tuberculosis klimination Framework.
It is worth noting that “Indian hospitals” were initially welcomed by many First Nations who were under
the impression that reasonable healthcare was part of treaty terms. In reality, “Indian hospitals"were
crowded, underfunded, and poorly staffed,serving to segregate sick Indigenous people from the rest
of the population. They were also the site of the cycle of apprehension, coercive sterilization, chemical
and physical restraints, and scientific experimentation, all of which inflicted significant morbidity
and mortality. When the Canadian government began closing these hospitals in the 1960s, Indigenous
people continued to fight for their right to healthcare, which was finally recognized in the Indian Health
Policy of 1979.
Coerced Sterilizations
Throughout the twentieth century, eugenics programs existed across the country. In the 1920s-1930s,
both Alberta and British Columbia legalized eugenic policies in the Sexual Sterilization Acts which
were not repealed until the 1970s.To limit reproduction of ”unfit’’ people in the eyes of the government,
Indigenous women were disproportionately targeted. This is referred to as forced or coerced sterilization
and, according to various accounts by Indigenous women across the country, involved any number of
the fallowing:
•tubal ligations being performed without consent
•being falsely told that a procedure is reversible
•being pressured into signing consent forms while actively in labour or on operating tables
•being given an ultimatum to undergo a tubal ligation or risk child apprehension
It is important to note that many sterilizations also occurred outside legislation, in federally run “Indian
hospitals," and some have been documented as recently as 2018.At least 100 Indigenous women have
come forward with accounts of coerced sterilization by physicians and nurses,spanning from the 1970s
until 2018.

Sixties Scoop and Indigenous Child Welfare
The “Sixties Scoop” (Johnson, 1983) (1951-1980s) refers to the government-mandated practice of
removing Indigenous children from their families without consent for placement in foster care or
adoption. As residential schoolsstarted to close, many children were transitioned to child welfare
facilities as the state deemed Indigenous parents unfit to care for their children - a legacy that persists
today. Similar to the Indian Residential School system,the goal was to assimilate Indigenous children
into a non-lndigenousfamily, rather than to directly provide child welfare to Indigenous communities.
Though Indigenous bands have increasingly been allowed to provide their own child welfare.Indigenous
children are still overrepresented in foster care.In 2016, Indigenous youth ages 0 to 4 made up about
half of all foster children in private households,despite being only 8% of total youth in this age group
in Canada. Youth with a history in government care may be at greater risk forsubstance misuse,street
involvement, and incarceration.
To this day, Indigenous children are disproportionately represented in the child welfare system and are
often apprehended for reasons directly related to the routine conditions of poverty.The apprehensions
that continue today echo the practices of the Sixties Scoop and residential school eras;the displacement
of Indigenous children separatesthem from their language and culture and hindersthe ability of
Indigenousfamilies to build resilience.Importantly,many Indigenous mothers and families avoid
accessing healthcare servicesfor fear of their children being apprehended.
Indigenous Approaches to Health and Wellness
• it isimportant to recognize the significant diversity amongst Indigenous nationsin the land now
known as Canada. Even within the same nation or language group,there will be variability in
practices. Despite this diversity,there are some ideas that recur across many nations
• restoring balance in the four realms ofspiritual,emotional, mental,and physical health of a person
acting as an individual, as well as a member of a family, community,and nation
ideas represented by the medicine wheel of First Nations peoples,the Learning Blanket of Inuit
peoples, and the Metis tree model all share a worldview based on holistic lifelong learning and
wellness
Indigenous medicines may take many forms (song,dance,smudge,ceremonies, plant medicines,
etc.)
practiced by experts who have decades of apprenticeship
while allopathic medicine often focuses on treating illness (like HTN or DM),Indigenous
medicine may understand the cause of a condition and the approach to healing in a different way
than a biomedical guideline
Indigenous medicine may focus on quality'oflife and not just cure
• cultural humility
cultural humility is a respectful, person-centered way of bringing curiosity and compassion
when a patient is willing to come forsupport
it takes courage to be humble enough to admit that we do not know what we do not know
Indigenous medicine is thousands of years old and eludes randomized controlled trials
Traditional Medicine is unlikely to interfere with Western Therapies
Latin root of “curiosity" is “cura,” which means “to care.
” Caring aboutsomeone’
s healing and
their beliefs about what may help them heal is a powerful act of witnessing and honouring.
Beginning with the belief that a person has wisdom about themselvesthat no one else does
and that we can be supporters of their healing, if they consent, can be a way to honour the
inherent wholeness of a person seeking care.This is especially true of Indigenous patientsfor
whom regaining self-determination is tantamount to regaining their wellness.
before assuming that an Indigenous person is interested in using traditional medicine, it is
important to begin with questions and curiosity'
.Dr.Chantal Perrotspeaks about the Patient
Dignity Questionnaire which advises healthcare workers to first ask patients, “What do I need to
know about you as a person to give you the best care possible?”
National Indigenous Health Organization (N1HO) offers 8 guidelines on practicing culturally
safe health care for Indigenous patientsincluding the need to allow Indigenous patientsto access
ceremony,song, and prayer;the need for information and for family support;guidelinesfor the
appropriate disposal of body parts and for handling death
Disease Prevention
Natural History of Disease
• course of a disease from onset to resolution
1. pathological onset
2. presymptomatic stage:from onset to first appearance ofsymptoms/signs
3. clinical manifestation of disease:may regressspontaneously, be subject to remissions and
relapses, or progress to death
Surveillance
• the continuous,systematic collection, analysis, and interpretation of health-related data needed for

• types ofsurveillance
• passive surveillance: reporting of disease data by all institutions that see patients, relying solely
on the cooperation of healthcare providers (laboratories, hospitals, health facilities, and private
practitioners)
most common, least expensive, but difficult to ensure completeness and timeliness of data
active surveillance: regular visits to health facilities for reviewing medical records to identify
suspected cases of disease under surveillance,or active testing of a population for the presence of
a disease
resource-intensive, used when a disease is targeted for eradication where every possible case
must be investigated, or for outbreak investigations
sentinel surveillance:selective reporting of disease data from a limited network of carefully
selected reporting sites with a high probability of seeing cases in question
well-designed system can be used to signal trends, identify outbreaks, and monitor the
burden of disease in a community in a timely and cost-effective manner compared to other
kinds of surveillance
may not be as effective in identifying rare diseases, or diseases that occur outside the
catchment area of sentinel sites
