Wearable devices and portable technologies are changing the way health is measured.

Analyse how these innovations have shifted health assessment beyond hospitals and clinics, and discuss the consequences of this shift for both healthcare professionals and individuals managing their own health.   (8 marks)

Show Answers Only

Overview

  • Wearable devices and portable technologies have changed how health is measured. These tools now connect personal data with professional care.
  • This change presents new opportunities and challenges for individuals and healthcare workers.

Consequences for health professionals

  • Smartwatches and portable ultrasounds are two examples where consumer wearable devices interact with clinical practice.
  • A smartwatch measuring heart rate can connect to digital health records, allowing continuous updates.
  • Similarly, portable ultrasounds enable rural doctors to diagnose without hospital imaging.
  • This interaction leads to earlier identification of problems and faster responses.
  • The implication is that healthcare becomes more proactive, but professionals must adapt to the increased flow of patient data that has become available.

Consequences for individuals

  • Continuous monitoring by individuals influences their health behaviours.
  • Devices that track sleep, steps, or diet affect motivation and self-management. For example, reminders to move or log food intake result in behaviour change.
  • At the same time, constant alerts cause stress or over-reliance on numbers.
  • This relationship shows the double impact: empowerment on one hand, anxiety on the other.
  • Healthcare workers must guide patients to interpret this information accurately and react appropriately.

Implications and Synthesis

  • Together, these technologies create a system where individuals gather data and professionals interpret it.
  • This means that roles are shifting, with patients more involved in their care.
  • The significance is improved access and prevention, but also greater demand for professional support.
  • Therefore, wearable technology is critically reshaping health measurement and redefining patient–professional relationships.

Explain how early diagnosis technologies can improve health outcomes. In your answer, give examples of TWO relevant technologies.   (5 marks)

Early detection enables timely treatment.

  • PET scans, for example, identify abnormal cell activity before symptoms appear. This occurs because these scans detect metabolic changes at cellular level.
  • As a result, doctors can start treatment when diseases are most responsive. This leads to higher survival rates and better prognosis.

Precise identification prevents disease progression.

  • The ACEMID system uses 92 cameras to create 3D body models that identify every mole within 1 second. This works by detecting minute changes in size or appearance.
  • Consequently, melanomas are caught before spreading.
  • This triggers immediate medical intervention, which means that cancer doesn’t advance to dangerous stages.

Comprehensive imaging reduces misdiagnosis

  • Advanced scanning generates detailed internal views. This process ensures doctors see exactly what’s happening inside the body.
  • Therefore, treatment plans target the actual problem. This in turn prevents unnecessary procedures and reduces patient stress.
  • The underlying reason is that accurate diagnosis creates appropriate treatment pathways from the start.

How do 3D holographic models most effectively improve cardiac diagnosis?

  1. They replace the need for other diagnostic tools, creating efficiencies in specialist care
  2. They provide detailed visualisation of heart anatomy for clarity of diagnosis
  3. They show high resolution external heart features
  4. They support decision-making by improving patient understanding of heart conditions
Show Answers Only

\(B\)

Show Worked Solution
  • B is correct. 3D models improve cardiac diagnosis by giving detailed visualisation of internal heart anatomy, helping doctors identify issues.

Other options:

  • A is incorrect. Holographic models complement, rather than replace, other diagnostic tools such as CT, PET, or MRI scans.
  • C is incorrect. The main benefit is not viewing external features, but understanding internal cardiac structures.
  • D is incorrect. While these models can improve patient understanding, their primary role is improving diagnostic accuracy.

The ACEMID system contributes most effectively to early melanoma diagnosis by:

  1. Taking high resolution photographs of suspicious moles
  2. Using cameras to create a 3D body model that identifies and measures moles
  3. Facilitates more effective patient self-examination
  4. Comparing mole changes over time using advanced imaging software
Show Answers Only

\(B\)

Show Worked Solution
  • B is correct. The ACEMID system uses 92 cameras to create a 3D body model (avatar) that identifies, maps and measures moles, enabling early detection of melanoma.

Other options:

  • A is incorrect. While high-resolution photos assist dermatologists, ACEMID provides more comprehensive body-wide imaging, not just individual mole photographs.
  • C is incorrect. ACEMID is a diagnostic tool used by professionals, not primarily designed for self-examination.
  • D is incorrect. Although advanced imaging software can compare mole changes, ACEMID’s key contribution is its 3D whole-body modelling.

Which best describes the role of the ACEMID system in early diagnosis?

  1. Measures oxygen saturation levels
  2. Tracks sleep cycle irregularities
  3. Creates a body avatar for melanoma detection
  4. Assists surgeons with robotic movements
Show Answers Only

\(C\)

Show Worked Solution

  • C is correct. The ACEMID system creates a 3D body avatar using high-resolution imaging to detect and track moles.

Other options:

  • A is incorrect. Oxygen saturation levels are measured using pulse oximeters, not the ACEMID system.
  • B is incorrect. Sleep cycle irregularities are tracked with apps and wearable devices.
  • D is incorrect. Robotic movements are linked to precision surgery.

Which technology is commonly used for early detection of cancer?

  1. PET scan
  2. Fitness tracker
  3. Ultrasound imaging
  4. Sleep app
Show Answers Only

\(A\)

Show Worked Solution

  • A is correct. A PET scan is commonly used for the early detection of cancer, as it identifies abnormal metabolic activity associated with tumour growth.

Other options:

  • B is incorrect. Fitness trackers measure steps, heart rate, and activity but cannot detect cancer.
  • C is incorrect. Ultrasound imaging can assist in identifying some abnormal growths but is not a primary tool for early cancer detection compared to PET scans, CT scans, or MRI.
  • D is incorrect. Sleep apps track sleep behaviours and patterns, not disease detection.

Show Answers Only

\(C\)

Show Worked Solution
  • C is correct: New technologies enable earlier disease detection and diagnosis.

  • A is incorrect: Emerging technologies often have limited initial accessibility.
  • B is incorrect: New technologies typically expensive during early adoption.
  • D is incorrect: Technologies complement rather than replace Medicare/PBS systems.

HMS, HAG 2015 HSC 1 MC

Which of the following is the main benefit of emerging treatments and technologies in health care

  1. Reduced costs for health care
  2.  Reduced dental health problems
  3. Improved early detection and screening procedures
  4. Improved waiting times for surgery in public hospitals
Show Answers Only

\(C\)

Show Worked Solution
  • C is correct: New technologies primarily enable earlier disease identification and screening.

Other Options:

  • A is incorrect: Technology typically increases rather than reduces healthcare costs.
  • B is incorrect: Too specific, not the main overall benefit.
  • D is incorrect: Technology doesn’t directly address surgical waiting times.
