[P] A key benefit of wearable technology is that continuous monitoring can identify health risks earlier than traditional healthcare.
[E] Smartwatches track heart rhythm throughout the day, so they can detect irregularities that may not appear during a brief GP visit and flag them for follow-up.
[Ev] For instance, the Apple Heart Study had over 400,000 participants. About one-third of those notified of an irregular pulse who completed follow-up monitoring were confirmed to have atrial fibrillation.
[L] As a result, individuals can seek treatment earlier, reducing the risk of serious outcomes such as stroke.
[P] However, this must be weighed against concerns about data accuracy and unequal access.
[E] Consumer wearables are not medical-grade devices, so inaccurate readings can create false reassurance or unnecessary anxiety. Device cost also means the benefits are concentrated among people who can afford them.
[Ev] A Stanford study found that none of seven popular wrist-worn devices measured energy expenditure accurately, even though their heart rate readings were generally reliable.
[L] Nevertheless, when health professionals interpret wearable data rather than individuals relying on it alone, the benefits of earlier detection outweigh these limitations.

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)

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.

A sleep-tracking app records time awake, time asleep, and oxygen levels. What is the purpose of this technology?

Provide an early diagnosis of cardiovascular disease
Help identify patterns for further medical assessment
Perform minimally invasive surgery
Replace the role of medical imaging

Show Answers Only

\(B\)

Show Worked Solution

B is correct. An app that records time awake, time asleep and oxygen levels helps identify patterns in a person’s sleep which can be used for further medical assessment.

Other options:

A is incorrect. The app does not diagnose cardiovascular disease although it may indicate irregularities that require professional follow-up.
C is incorrect. Minimally invasive surgery is part of precision surgery, not health monitoring via apps.
D is incorrect. Sleep apps do not replace medical imaging, rather they collect lifestyle data.

Which health condition could be monitored using a smart contact lens?

Blood glucose levels
Blood clotting
Sleep quality
Lung function

Show Answers Only

\(A\)

Show Worked Solution

A is correct. A smart contact lens can be used to monitor blood glucose levels.

Other options:

B is incorrect. Blood clotting requires medical imaging or laboratory testing, not wearable eye-based technology.
C is incorrect. Sleep quality is tracked using devices such as smartwatches, rings or apps, not contact lenses.
D is incorrect. Lung function is assessed through respiratory monitoring devices.

Which of the following best explains how wearable technology contributes to preventative healthcare?

It warns the user when surgical treatment is needed
Diagnoses diseases without medical input
Removes the need for professional health consultation
Tracks lifestyle behaviours and identifies early risk factors

Show Answers Only

\(D\)

Show Worked Solution

D is correct. Wearables track lifestyle behaviours such as physical activity, sleep and heart rate, which can help identify early risk factors for chronic conditions.

Other options:

A is incorrect. Wearables cannot directly warn a user when surgical treatment is needed; that requires medical assessment and diagnosis.
B is incorrect. Wearables provide health data but do not independently diagnose diseases without professional interpretation.
C is incorrect. Professional health consultation remains essential; wearables complement, rather than replace, medical expertise.
