Lesson 17 · Technology and data in healthcare
Digital health: connecting health information, and what it costs to do it
Digital health exists to solve one problem: a person's health information sits in pieces held by organisations that cannot see each other's pieces. That is the fragmentation problem from earlier in this module, restated as an information problem — which is why evaluating digital health is really evaluating whether a technology can fix something structural.
You are unconscious in an emergency department in a city you were visiting. The staff do not know your name.
List the five pieces of information you would most want them to have. Then say, for each, where that information currently lives — and whether the emergency department could get it.
- Define digital health, and say what problem it exists to solve.
- Describe what services exist in Australia.
- Evaluate to what extent digital health has been successful in connecting health information — the sub-point that requires a judgement.
- Explain the challenges and opportunities it creates for individuals and for organisations.
- Explain why an information technology can fail for reasons that are not technical.
- Digital health — the use of information and communication technology to deliver, coordinate and record health care.
- Electronic health record — a person's health information held digitally; may be a single provider's record or a shared one.
- My Health Record — Australia's national shared health summary, holding key documents from providers who choose to upload to it.
- Interoperability — the ability of different systems to exchange information and use it. The central technical problem of digital health.
- Telehealth — consultation by video or telephone rather than in person.
- Electronic prescribing — a prescription issued and dispensed digitally rather than on paper.
- Secure messaging — sending clinical information directly between providers in a protected form.
- Opt-out — a participation model in which people are included by default and must act to be excluded.
- Digital exclusion — being unable to use a digital service through lack of device, connectivity, skill or confidence.
Digital health is not a technology; it is a response to a specific failure. In a system where funding, delivery and regulation are split across governments and sectors, a person's health information ends up in pieces held by organisations that cannot see each other's pieces: the general practice, the specialist, the pathology provider, the pharmacy, two hospitals and an aged care service.
The consequences are concrete, and they are the reason this dot point sits in the syllabus:
- Tests are repeated because the previous result cannot be seen — cost, delay and sometimes radiation.
- Medicines are prescribed without the full list, which is one of the more common causes of preventable harm.
- The patient becomes the carrier of information, which fails exactly when they are least able to do it: unconscious, confused, unwell, or speaking a different language.
- Care is duplicated or missed at the seams, particularly on discharge and between health, aged care and disability services.
Digital health is the attempt to make a fragmented system behave, from the patient's point of view, like a single one. That framing is worth stating in any answer, because it explains both the ambition and the difficulty.
Quick check: Digital health is best understood as a response to which underlying problem?
- My Health Record. The national shared summary. It holds discharge summaries, medicines information, pathology and imaging reports, immunisation history and shared health summaries. It operates on an opt-out basis, so most Australians have one, and individuals control access settings and can see who has viewed their record. Crucially, it is a summary that providers choose to contribute to, not a complete clinical record automatically fed by every system.
- Telehealth. Video and telephone consultation, expanded very rapidly during the pandemic and now a permanent part of the system. It removes distance for the part of care that does not require physical examination.
- Electronic prescribing. Prescriptions issued and dispensed digitally, which removes the paper token and the trip to collect it.
- Secure messaging. Direct transfer of referrals, results and discharge information between providers — unglamorous, and probably the single largest practical improvement available.
- Provider electronic records. Nearly every general practice and hospital keeps digital records; the difficulty is that they were built separately and frequently cannot exchange information usefully.
- National registers for immunisation, organ donation and cancer screening, which quietly work well and are the clearest success in this list.
- Consumer-facing tools — appointment booking, results access, apps — and the national health information services people telephone or search.
Notice the pattern: the components that work best are the ones with a narrow, defined purpose and a single custodian — registers, electronic prescribing, secure messaging. The component with the broadest ambition is the one whose success is most contested.
True or false: My Health Record is a shared summary that providers choose to contribute to, rather than a complete clinical record automatically populated by every system a person uses.
This sub-point asks “to what extent”, which requires a graded judgement rather than a verdict. The honest answer has three parts.
Genuine successes
- Registers work. Immunisation and screening registers connect information reliably, at national scale, and are used every day.
- Telehealth is established. A decade of slow progress happened in months under necessity, and it did not reverse. It is now a real access improvement for distance and mobility.
- Electronic prescribing and secure messaging remove friction and error, quietly and without controversy.
- Coverage exists. Most Australians have a My Health Record, which is not nothing — the infrastructure is in place.
Where it has fallen short
- Coverage is not use. Having a record is not the same as it being populated, viewed or relied on, and a record clinicians do not consult adds nothing.
- Contribution is uneven. If some providers upload and others do not, the summary is incomplete — and an incomplete record is worse than none, because it can be trusted as complete.
- Interoperability remains the hard problem. Systems built separately do not exchange information usefully just because a national platform exists.
- Clinical usability. A record that is slow to search, or dumps unstructured documents on a clinician mid-consultation, will not be used regardless of what it contains.
- Trust. Privacy concern at introduction affected participation, and trust once damaged is slow to rebuild.
The graded judgement: digital health has succeeded where the task was narrow and the custodian single, and has succeeded only partially where the task was to connect information across organisations that were never designed to share it. The failure is not technical — it is that the fragmentation digital health was meant to overcome is the same fragmentation that makes contribution voluntary and inconsistent.
That sentence is the analysis this dot point is asking for, and it is a specific instance of a general truth: a technology cannot solve a structural problem it is embedded in.
Fill the gaps. The ability of different systems to exchange information and use it is called . A participation model in which people are included by default and must act to be excluded is called .
The sub-point names both groups, and they experience digital health differently. Answer for both.
For individuals
Opportunities. Access to your own information, so you can check, correct and carry it. Fewer repeated tests and repeated histories. Safer care in an emergency or away from home. Real access improvement through telehealth for people limited by distance, mobility, work hours or caring responsibilities. And a shift in the relationship: a person who can see their own record is better placed to participate in decisions.
Challenges. Privacy, and the reasonable question of who can see what — which matters most for sensitive information and for people in situations where disclosure carries risk. Digital exclusion, which follows the familiar lines of age, income, remoteness, disability and language. Reading a record without context can alarm rather than inform. And an incomplete record can mislead a person as easily as a clinician.
For organisations
Opportunities. Fewer duplicated tests and safer prescribing. Better coordination across the seams, which is the cheapest available improvement in a fragmented system. Data for planning, quality improvement and research. And workforce reach extended through telehealth, which is the constraint behind almost every other reform in this module.
Challenges. Cost and disruption of implementation, borne by providers while the benefit is spread across the system — a classic reason a good idea is not adopted. Time in the consultation, which is the scarcest resource in primary care. Security obligations, since health data is a target. Medico-legal uncertainty about what a clinician is expected to have read. And the interoperability problem, which is expensive and unglamorous and is the actual bottleneck.
One structural observation worth a sentence in an evaluation: the costs of digital health fall on providers and the benefits fall on the system and the patient. Where costs and benefits land on different parties, adoption is slow no matter how good the idea — and that, rather than technology, is what has determined the pace here.
Two truths and a lie. One of these statements about digital health is false. Find it.
Five conditions. None of them is a new technology, which is the point.
- Contribution has to be the default, not a choice. A shared record is only as good as what is in it, and voluntary contribution guarantees an incomplete record.
- It has to be faster than not using it. Clinicians work in short consultations. A system that costs thirty seconds will be used; one that costs three minutes will not, whatever its contents.
- Interoperability has to be built, not hoped for. Common standards, enforced, so systems can exchange meaning rather than documents. Expensive, invisible, and the actual bottleneck.
- Trust has to be maintained, not assumed. Clear rules about access, visible logs, real consequences for misuse, and honesty when something goes wrong. Trust lost once is very expensive to recover.
- Digital exclusion has to be planned for. Non-digital pathways must remain, or every gain is a gain for people who already had the most access — the distribution rule again.
The general lesson, and the one to take into any question about health technology: digital health's limits are the health system's limits. It was asked to connect a system that is deliberately not unified, and it has connected exactly as much as that system permits.
Activities · evaluate, do not describe
For each situation, say which digital health service would help, what has to be true for it to help, and what would happen if that condition failed.
A person collapses while travelling and cannot give a history; they take several medicines.
A patient has the same blood test repeated three times in five weeks by three different providers.
A person in a remote community needs a specialist review of a stable chronic condition.
An older person is discharged from hospital and their general practitioner does not learn what changed.
Match each digital health service to the problem it principally addresses.
- Shared health summary
- Telehealth
- Secure messaging
- National registers
- Key information unavailable when a person cannot supply it themselves
- Distance and mobility preventing a consultation that needs no examination
- Referrals, results and discharge information not reaching the next provider
- Knowing reliably, at national scale, who has been immunised or screened
Write a four-paragraph evaluation of the extent to which digital health has succeeded in connecting health information in Australia.
Paragraph one: what it was for. Paragraph two: where it has succeeded, with examples. Paragraph three: where it has not, with the reason rather than the complaint. Paragraph four: a graded judgement, and one condition that would have to change.
Constraint: your paragraph three must explain why, not merely state that adoption has been uneven.
Lock it in. In one sentence, explain why an incomplete shared health record can be more dangerous than having none at all.
Evaluate the extent to which digital health has been successful in connecting health information across the Australian healthcare system.
Evaluate demands a judgement against criteria, and the phrase “the extent to which” tells you the answer is a matter of degree rather than yes or no.
Plan: criteria, the case for, the case against, a verdict that says how far, then a qualification.
Success will be judged against three criteria: whether health information follows the patient between providers, whether clinicians actually use the connected record in practice, and whether connection has translated into measurable improvements in care.
Against the first criterion there has been substantial progress. My Health Record provides a national repository accessible across states and sectors, so discharge summaries, prescriptions, pathology and imaging reports can follow a patient who moves between a hospital, a general practitioner and a pharmacy. Electronic prescribing and secure messaging have removed paper handoffs, and telehealth expanded rapidly and permanently, connecting rural patients to specialists without travel.
Against the second and third criteria success is much more limited. Upload and use by clinicians has been uneven, so records are frequently incomplete, and a record that cannot be relied upon to be complete is not used — a self-reinforcing failure. Systems across states, private providers and primary care remain poorly interoperable, so information is transferred rather than genuinely shared. And benefit depends on digital access and literacy, so older Australians, people with low literacy and those in areas with poor connectivity gain least, despite often having the most complex care to coordinate.
Digital health has therefore been substantially successful at building the infrastructure for connection and only partially successful at achieving connection in practice. The technical capacity to move information now exists nationally; what has not followed is consistent clinical use, genuine interoperability between systems, and equitable access to the benefit.
The qualification is that the remaining barriers are organisational and behavioural rather than technical, which means further progress depends on clinical workflow, incentives and trust rather than on further system development.

Explain the challenges and opportunities digital health presents for individuals and organisations.
The stem has two dimensions — challenges and opportunities, individuals and organisations. Four combinations, and an answer covering only two of them is incomplete.
Plan: name the principle, then take individuals and organisations in turn, covering both sides for each.
Digital health separates health information from the place it was created. That single change generates both the opportunities and the challenges, because information that can travel to where it is useful can equally travel to where it is not authorised.
For individuals the opportunity is access and control: a person can see their own results, medication history and appointments, which supports self-management and reduces repeated tests when they move between providers. The corresponding challenge is that the benefit requires connectivity, a device and the literacy to use both, so those with the most complex health needs — often older or socioeconomically disadvantaged — are least able to realise it, and their sensitive information is held in a system they cannot readily audit.
For organisations the opportunity is coordination and planning: shared records reduce duplicated investigations and adverse events from unknown medication histories, and aggregated data supports service planning. The challenge is that connection multiplies exposure, since a breach in one participating system compromises data drawn from many, and the cost of interoperability, staff training and cyber security falls on providers whose funding models were not designed to carry it.
The opportunities and challenges are therefore not independent: each opportunity is created by the same movement of information that creates its corresponding risk, which is why digital health is governed through access controls and consent rather than by restricting connection itself.

Return to card 01. You listed five pieces of information and where each lives. How many of the five would actually be reachable by an emergency department in another city today? That number, honestly estimated, is your answer to “to what extent has digital health succeeded” — and it is neither zero nor five.
Multiple choice · 5 questions

Multiple choice: 1 → B. 2 → B. 3 → B. 4 → A. 5 → B.
Activity 1 model answers: 1 → The shared health summary. It helps only if the person's providers have uploaded a current medicines list and the emergency department can and does look. If contribution is inconsistent, the record may show an outdated list, which is more dangerous than no list because it may be trusted. 2 → Shared pathology reporting, or secure messaging between providers. It helps only if all three providers can see the result and check before ordering; if one system cannot exchange with the others, the test is repeated regardless. 3 → Telehealth, with remote monitoring for the measurements. It helps only if connectivity and a local practitioner or health worker are available for anything physical; where connectivity fails, the access gain evaporates for exactly the population it was meant to serve. 4 → Electronic discharge summaries through secure messaging. It helps only if the hospital sends promptly, the general practice receives into a usable format, and someone reads it; a summary that arrives weeks later or as an unstructured document has not closed the seam.
SA 1 (4 marks): Digital health defined as the use of information and communication technology to deliver, coordinate and record care [1], with the problem it addresses stated — information held in pieces by organisations that cannot see each other's pieces [1]. Two services described accurately from My Health Record, telehealth, electronic prescribing, secure messaging, national registers or consumer tools [2].
SA 2 (5 marks): For individuals: opportunities including access to and control of their own information, fewer repeated tests and histories, safer emergency care, and telehealth access for distance, mobility or work constraints; challenges including privacy, digital exclusion along familiar lines of age, income, remoteness, disability and language, and information without context [2]. For organisations: opportunities including fewer duplicated tests, safer prescribing, better coordination at the seams, data for planning, and extended workforce reach; challenges including implementation cost and disruption, consultation time, security obligations, medico-legal uncertainty and interoperability [2]. The structural point for the fifth mark [1]: costs fall on providers while benefits fall on the system and the patient, so adoption is slow regardless of merit.
SA 3 (6 marks): Purpose stated — to make a fragmented system behave, from the patient's point of view, like a single one [1]. Successes identified with examples: national registers, telehealth's rapid and durable expansion, electronic prescribing and secure messaging, and near-universal coverage of the shared record [2]. Shortfalls identified with reasons rather than complaints: coverage is not use; contribution is voluntary and therefore uneven, and an incomplete record may be trusted as complete; interoperability between separately built systems remains unsolved; clinical usability inside a short consultation; and trust affected at introduction [2]. A graded judgement [1]: successful where the task was narrow and the custodian single, only partially successful where the task was to connect organisations never designed to share — because a technology cannot resolve a structural problem it is embedded in, and the fragmentation digital health was meant to overcome is what makes contribution optional.
“To what extent” questions want a graded judgement with a reason for the grading, and this dot point is the clearest place in the module to practise that shape. Succeeded here, not there, and here is what explains the difference.
The final lesson of this inquiry question turns from connecting information about one person to using information about everyone — big data, its uses, and the privacy questions that follow from it.
