Week 7 Flashcards

1
Q

What are the National Health Response Arrangements used for?

A
  1. inform and guide a coordinated Australian health sector response to, and recovery from, emergencies of national consequence; and
  2. provide a strategic planning framework for guidance to the future revisions of existing health sector emergency plans.

Q

What is the difference between the NatHealth Atrrangements and other emergency response plans?

A

Unlike a plan that is activated in times of need, the NatHealth Arrangements remain in place at all times.

Q

When are the NatHealth Arrangments utilised?

A

in response to domestic or international event that:
that:
- impacts or threatens to impact two or more states and/or territories and across jurisdictional borders;

  • has the potential to overwhelm or exhaust a state and/or territory’s health assets and resources; or
  • its scale or complexity warrants a nationally coordinated response.

Q

What is the national disaster resilience framwork?

NOT ON EXAM

A

how we overcome and recover from a disaster.

“Protecting Australia from the impacts of disasters is a shared responsibility that cannot be borne by the emergency management sector alone.

Q

who does the emergency management manual cover?

A

“Protection and preservation of life is paramount this includes:

  • Safety of emergency services personnel; and
  • Safety of community members, including vulnerable community members and visitors/tourists located within the incident area…”

A
Comprehensive Approach
     • Before: Prevention (Mitigation) & Preparedness

Q

WHat are the ICS (AIIMS) principles?

A
  • One agency is controller of an incident
  • Functional delegation
  • Management by objectives
  • Management plans
  • Span of controls
  • Command within agencies
    • When CIM of HC role becomes too large or complex to be
    undertaken by one individual, some of the functions are
    delegated to another person
    • Division of functions
    • Control -> operations -> planning -> logistics

Q

what are the elements of an Incident Action Plan

SMEAC PLAN

A
  • Situation – what has happened
  • Mission – what do we need to achieve
  • Execution – how are we going to achieve it
  • Administration – what are the details
  • Command & Communication – who is doing what and how will we
    communicate

Q

What is the communicable disease triad?

A

Host
• Intrinsic
• Behaviours / Extrinsic

Agent
• Eg pathogenicity, infectiousness, infectious dose, virulence,
immunogenicity, drug resistance

• Physical
• Social

16
Q

Define pathogenesis?

A

mechanism by which pathogen produces disease

17
Q

Define virulence?

A

degree of pathogenicity (disease inducing ‘power’ of pathogen)

18
Q

Define susceptible in relation to disease

A

able to contract infection, ie at risk of transmission

19
Q

Define reservoir in relation to disease

A

habitat where a pathogen normally lives, grows or multiplies

may be human, animal, environment

20
Q

Define carrier in relation to disease

A

asymptomatic person or animal that harbours a pathogen and

serves as potential source of infection

21
Q

define vector in relation to disease

A

living organism that plays a role in the transmission of a pathogen
to a susceptible host

22
Q

Define Arbovirus

A

arthropod-borne virus transmitted by arthropod vectors

23
Q

Define Zoonosis

A

infectious disease transmitted from vertebrate animals to

humans

24
Q

What are some examples of direct mode of transmission

A

transfer of a pathogen from an infected host to a
susceptible host ie person to person

  • Skin to skin eg Gp A strep
  • Sexual contact
  • Blood borne
  • Respiratory droplet
  • Vertical (mother to foetus)
  • Transplant
25
Q

What are some examples of indirect mode of transmission

A

transmission of a pathogen to a susceptible host via the aid of a vector, vehicle or air

  • Food borne
  • Water borne
  • Soil borne
  • Fomite borne
  • Vector borne
  • Animal borne
  • Air borne (aerosol)
26
Q

What is the reproductive ratio (R)?

A

average number of infections resulting from an

infectious case ie average number of successful transmissions

27
Q

what is the purpose of health surveillance?

A

Purposes
• determine the magnitude of a disease
• examine trends over time
• examine differences in different settings
• identify risk factors
• identify cases that require defined response(s)
• detect outbreaks
• monitor impact of health interventions
• facilitate future planning, interventions etc

28
Q

What are the types of disease surveillence?

A
  • Syndromic surveillance
  • Disease surveillance
  • Passive v active
  • Enhanced surveillance
  • Laboratory based
  • Sentinel surveillance
  • Case definitions
  • Cases
29
Q

What is included in the infection control program?

A
  • Hand hygiene
  • PPE
  • Isolation
  • Surveillance: monitoring and prevention
  • Vaccination
  • Cleaning / disinfecting / sterilisation
  • Outbreak investigation and management
  • Antimicrobial stewardship
30
Q

What is an endemic?

A

disease that occurs in the community with incidence

falling within an expected range

31
Q

what is an epidemic

A

occurrence of disease in the community/region clearly in

excess of the normal expected incidence

32
Q

what is an outbreak

A

equivalent to epidemic, but usually taken to refer to the

first cluster or epidemic cases, or to a small epidemic

33
Q

What is contact tracing?

A

interrupts ongoing transmission, finds those at high risk of
infection and those who may benefit from Rx, and counsel and give information
as needed

34
Q

what is quarantine?

A

separates and restricts the movement of people who have been

exposed to a communicable disease (observe if they become symptomatic)

35
Q

what is herd immunity

A

critical levels of immunisation coverage required to prevent

outbreaks of a specific disease, in a given context

36
Q

what are the steps of investigating an outbreak

A
  • Establish existence of outbreak
  • Verify diagnosis
  • Define and identify cases
  • Perform descriptive epidemiology
  • Determine who is at risk
  • Develop and evaluate hypothesis
  • Perform additional studies
  • Implement control and prevention measures
  • Communicate findings
37
Q

What do you look for in investigating an outbreak?

A
  • Cause of disease
  • Source of infection
  • Mode of transmission
  • Who is at risk
  • Control / prevention
38
Q

What are the 5 elementns of risk communication?

A
  • Trust
  • Early announcement
  • Transparency
  • Listening
  • Operational planning
39
Q

What is the equation for working out the reproductive ratio (R) in infectious disease?

A

R = C x P x D

Reproductive ratio = Contact rate x probability of transmission x infectious period
