Q

Why should inequities be reduced?

A

Inequities are unfair. People are not given freedom to determine their health outcome. Lack of freedom caused by determinants beyond their control.

Reducing inequities is cost effective. Ensures workforce remains healthy and effective, and reduces costs of treatment. Usually involves only reallocation of resources according to need which adds no additional cost.

Inequities are avoidable. If health outcomes are different at different locations, it means that there are ways to change it. They stem from environmental factors which can be amended at the policy level.

Inequities affect everyone. By affecting the health outcomes of the most at risk, it can have a flow on effect in the form of incohesive society.

Q

Findings of 7 Modes Study

Hint: Distance and time

A

Average exposure to pollutants decrease with increased distance from the centre of the road.
Active transporters are more exposed to pollutants as they take longer on their commutes, and they are not protected from exhaust etc.

43
Q

Ways to reduce exposure to pollutants.

A

Engineering interventiosnL Physical barrier between active transporters and vehicles.
Increase distance between active transporters and vehicles.
Policy level interventions: increase road calming measures in residential areas to reduce volume of traffic. Improve experience of active transporters. Ensure basic services are accessible by active transport.
Actively avoiding sources of pollution, such as walking on the less busy side of the road, or not stopping the bus where there is a lot of vehicle exhaust.
Behavioural changes: Walking in green spaces or further from sources of pollutants, such as on the opposite side of a busy road.

44
Q

Definition of Access

A

The end result of a process flowing from predisposing characteristics and enabling resources, through need (perceived and evaluated) to an ultimate health outcome.

45
Q

Potential Access

A

The amount of services available to clients.

46
Q

Realised Access

A

The amount of resources actually being used due to factors of the 5 dimensions of access.

47
Q

Availability

A

The knowledge/existence of service barrier.

Relationship between the volume and type of services available to the volume and type of services demanded.

48
Q

Questions regarding availability.

A
  1. All things considered, how much confidence do you have in being able to get good medical care for you and your family when you need it?
  2. How satisfied are you with your ability to find one good doctor to treat the whole family?
  3. How satisfied are you with your knowledge of where to get health care?
  4. How satisfied are you with your ability to get medical care in an emergency?
49
Q

Accomodation

Organisational barriers.

The relationship between the manner in which supply of resources is managed in preparation for clients.

50
Q

Questions regarding accommodation

A
  1. How satisfied are you with how long you have to wait for an appointment?

  3. How satisfied are you with how long you have to wait?
  4. How satisfied are you with how easily it is to contact your physician?
51
Q

Accessibility

A

Geographical Barriers. Relationship between location of supply and location of client. Must take into account time and cost of transport.

52
Q

Questions regarding accessibility.

A
  • How satisfied are you with how convenient your physician’s offices are to your home?
  • How difficult is it for you to get your physician’s office?
53
Q

Acceptability

55
Q

Affordability

A

Financial barriers. The relationship between the cost of provided services and the clients’ ability and willingness to pay. Links to other barriers- lower willingness to pay leads to accessibility issues as affordable gps are far away.

56
Q

Questions regarding affordability

A

How satisfied are you with your health insurance?
How satisfied are you with the doctors’ prices?
How satisfied are you with how soon you need to pay the bill?

57
Q

The Inverse Care Law

A

The availability of good healthcare varies inversely with need for it.
Due to tendency for paid healthcare to follow economic distributions, where willingness to pay increases availability.

58
Q

Characteristics of Big Data

A

Volume: Computing power needed to store and compute big data.
Velocity: How quickly can the data be processed and analysed?
Variety: The diversity in the type (texts, image) and source (administration, social media) of data.
Veracity: Accuracy and reliability of data, which can affect the quality of results of inquiries using this data.
Variability: Internal consistency of the data.
Value: Will the cost of obtaining and analysing data be paid off by the benefit that the results of the inquiry will have (for providing better health care for patients, or generating more profit).
Visualisation: Adequate use of infographic techniques to convey key trends in data that would not be visible from seeing datasets as numbers.

59
Q

Sources of Big Data

A

Medical records- HSU/ IDI.
Internet of Things
Data repositories containing data from past research.
Social media.

60
Q

Deterministic data linkage

A

Based on the same identifying information appearing in all datasets to be linked.

61
Q

Probabilistic data linkage

A

Using statistical weights assigned to data from different sets that do not match exactly to calculate how likely it is that they refer to the same individual.

62
Q

Benefits of the IDI

A

Links data from across multiple data sets to establish system wide insights.
Life course information- investigates how factors early in life can affect lifestyle outcomes later on.
Identifies risk and protective factors.
Performs predictive risk modelling.
Evaluate the effectiveness of particular interventions.
Identifies characteristics of groups with positive and negative outcomes- determinants of health.
Tailor interventions for people based on their similarities with studied groups. If they share this risk factor, then that risk factor can be targeted in interventions.

63
Q

What can’t you use the IDI for?

A

Following individuals who are utilising services- case management.
Identifying at risk individuals who could use an intervention.
Identify individuals who are abusing systems.
Although all of these seem like legitimate reasons, they involve identification of the individual to some degree and this undermines the de-identification of the data.

64
Q

Data Governance

A

Regulating practices and processes involved in data storage, transferring and use to ensure professional use of data assets.

65
Q

Data Quality

A

Regulating how the data is collected and the accuracy of the data being added. Large quantities of data is only reliable if the data going in is correct.

66
Q

Data output

A

Quality interpretation of results.

Administrative difficulties with analysing large amounts of data.

67
Q

Five Safes of Big Data

A

Safe people: Analysts of data must be trustworthy with confidential data, and competent with large amounts of data.
Safe projects: Data usage must be for public benefit, rather than victim blaming or stigmatisation.
Safe settings: Authorised and secure access to data, as well as safe transfer of data outside of this setting for use (ie: proper de-identification and encryption).
Safe data: Data is de-identified, so it is ‘safe’ to be seen by people who aren’t meant to see it because it doesn’t mean anything.
Safe output: See safe data, except in published results.
The gist is that safe use of data would involve protection of individual identity, and the knowledge and intent to do so.

68
Q

Implications of Big Data

A

Ability to conduct and experiment with hypothetical ‘what if’ scenarios to determine impacts of policy.
Inadvertent discrimination of groups in the population that can be identified by non-hidden aspects of data.
Difficult to control the spread of data.
Requires revisitation of privacy policies.

69
Q

Epidemiological Triangle

A

Agent: Microbe causing disease.
Host: Carrier of agent who may be suffering symptoms.
Environment: External factors enabling disease spread,

70
Q

P in PROGRESS

A

Place of Residence: Environmental determinants of health such as availability of healthcare infrastructure at areas of different SEP/ urban or rural areas.

71
Q

What is PROGRESS used for

A

Framework to guide analysis of inequities acting on groups which affect their health outcomes.

72
Q

First R in PROGRESS

A

Race/Ethnicity/Language/ Culture: Differences in experience due to social experiences of specific ethnic groups due to prejudices. Differing access to healthcare due to barriers of cultural practice imposed by cultural community, or barriers of language preventing easy communication.

73
Q

O in PROGRESS

A

Occupation: Encompasses negative determinants associated with work, such as poor working conditions or unemployment. Inequity in health outcomes between different careers due to inherent dangers.

74
Q

G in PROGRESS

A

Gender and Sex
Biological differences in outcome due to differences between sexes is unavoidable and not unfair.
Different gender-specific roles (assigned by societal expectation) contribute to inequity in health outcome as they cause exposure to different determinants. Social convention also leads to unfair treatment of different gender, leading to differing degrees of exposure.

75
Q

Second R in PROGRESS

A

Religion
Religion associated inequities exist when there is lower availability of healthcare to a group due to religious affiliations. Not unfair if treatment is rejected due to religious reasons.

76
Q

E in PROGRESS

A

Education
More educated people are more aware of the determinants of poor health and will take steps to avoid them. The lack of access to education beyond personal choice is unfair, and so will be the consequential difference in health outcome.

77
Q

First S of PROGRESS

A

Socioeconomic Position:
Higher SEP means improved living conditions and general quality of life. Enables individual to make healthy lifestyle choices. Inequitable as the absence of more accessible for the more deprived isn’t inevitable.

78
Q

Second S of PROGRESS

A

Social Capital: Refers to community and the social network around an individual. Improving connection means improved ability to access help. Linked to inequities leading to SEP as increased SEP inequality in a community reduces social cohesion.

79
Q

HSU Dataset

A

Collects hospitalisation and prescription data for each individual. Deficit data set as individuals must get sick to be recorded.
Can be used alongside other health data to see how interaction with healthcare system can have an effect on health outcome.
Data isn’t collected for epidemiological research.

80
Q

NZ Health Survey

A

20000 individuals interviewed per year and self-reported data on health status is collected. Self-reporting can lead to errors in BOM.

81
Q

Vital statistics

A

Nationwide dataset regarding births and deaths in the population. Useful as denominators and can be linked to healthcare data to investigate immunisation rate of newborn or causes of death (etc).

82
Q

Census

A

Collection of relevant personal information from every individual in a population. Investigates composition and allows division of population into cohorts. Cohorts can be used in epidemiology.

83
Q

Integrated Data Infrastructure

A

Combines data routinely collected by the government due to interaction with government agency. Deficit data set as such interaction usually stems from deficit.
Very representative. Allows linking of data between datasets.

84
Q

Prioritised Output Pros/Cons

A

PROS: Ensures all individuals are counted only once across all ethnic groups.
Allows less prevalent groups of policy importance to be represented.
CONS: Does not respect the right for individuals to identify as their chosen ethnicity.
Oversimplification of data.

85
Q

Stages of the Demographic Transition Model

A

Stage 1: High stable birth. High fluctuating death.
Stage 2: High stable birth. High decreasing death.
Stage 3: high decreasing birth. Low stable death.
Stage 4: Low stable birth and death.
