Opinion - Safe and Responsible Artificial Intelligence in Health Care


I wrote a submission as part of the public consultation on Safe and Responsible AI in Healthcare. I haven’t really ever done one of these before, but since it was interesting - I thought I might share it here.


1.      How can AI benefit health and care in Australia and how can we measure and deliver these benefits?

There are many possible ways AI could benefit health and care in Australia. It could assist in improving diagnostics, possibly improve patient outcomes (via detecting trends/clinical abnormalities), and may aid rural & remote areas.

In Radiology, it is already being noted that some AI systems are able to detect or flag possible issues for Radiologists to review – this also occurs for some Gastroenterologists who have advanced imaging systems integrated into their scopes.

From one Sydney specialist, their current comment is that “AI helps highlight or query areas that may not have been seen by the human eye – it doesn’t replace my role or my expertise, but acts almost like a live second opinion. In this way, I feel like I am providing clinically superior investigations but also have a form of backup”.

I believe one of biggest ways that AI can assist are in systems that use tap into clinical data/observation inputs to help predictive analytics – helping to identify deteriorating patients or flagging certain patients that may fall within risk of certain conditions. An example of this is the “the Ainsoff Deterioration Index” that made news in June 2023 – see publication (Link: Link: https://pubmed.ncbi.nlm.nih.gov/37150397/);

Bassin L, Raubenheimer J, Bell D. The implementation of a real time early warning system using machine learning in an Australian hospital to improve patient outcomes. Resuscitation. 2023 Jul;188:109821. doi: 10.1016/j.resuscitation.2023.109821. Epub 2023 May 5. PMID: 37150397 -

There are now ways and methods for patients to be monitored and assessed at home or outside the clinical setting; and changes in data received could be flagged or alerted for medical intervention. Any AI system should be measured and assessed to determine their benefits. This could be done via randomized controlled trials (RCTs) in healthcare settings and a system of consistent auditing.

2.      Can AI improve access to care, and what regulations could be amended or added to enable this?

Yes – I believe that AI would enable additional support for remote diagnostics, telemedicine, and mobile health apps in areas of need. I’m not an expert, and would have to defer to others with greater understanding of Australian healthcare regulations – but I think you would need to look at the; the Privacy Act 1988 and My Health Records Act 2012. These would need to be updated incorporate the use of AI.

As part of this, you may need to establish specific guidelines for AI-powered tools, ensuring that cover data protection, accuracy, and fairness standards. There may be similar regulations internationally that could be used to base this on. One that would be worth reviewing would be the EU's Artificial Intelligence Act.

 

3.      What risk does AI pose to patients/consumers or healthcare professionals? Are the risks high or low? What criteria could be used to characterise risk? Should consumers be informed when AI is used in these low-risk ways?

I believe the main risks that AI could pose is inaccurate diagnoses, problems with bias in how algorithms operate, the concern about privacy breaches / how data is governed, and perhaps an eventual over-reliance on automation.

Risks could be high (ie, if AI makes a critical error which leads to a mis or missed diagnosis or inappropriate/missed treatment) or the risks could be low (ie for things like administrative assistance in appointment scheduling). If AI tools are adopted, then organisational risk-management systems would need to be updates to assess the severity of the clinical impact, the level of autonomy given to the AI system, and the degree of human oversight.

Consumers should be informed whenever AI is being used – and this should be explained clearly, and staff given resources to handle any questions or concerns.

 

4.      What factors are important for rural, regional or remote Australia when assessing the benefits, risks, and safety of AI? Are there other communities that face specific risks when implementing AI in health care? What considerations should be made to ensure all Australians have access to the benefits of AI?

In rural areas one factor that would need to be considered would be quality and accessibility to sufficient internet services. There are also things like staffing / expertise shortages, and the level of health literacy. AI could assist by enabling telemedicine, remote monitoring, and perhaps automated diagnostics. There is also a possible concern surrounding the amount of reliance on these tools – particularly with risk of system failures.

 

5.      Should health care professionals have a choice about whether they use AI as part of their work?

Yes, in every case healthcare professionals should have the autonomy to decide whether to incorporate AI tools into their practice or not. Many healthcare professionals may wish to rely on more conventional (traditional) methods. If AI systems are implemented or adopted, there should always be adequate training and support so that clinicians feel confident in using them.

 

6.      What unique considerations are specific to AI in health care, and why? Should the government address them through regulatory change?

Healthcare requires a high level of accuracy, accountability, and transparency due to the life-or-death stakes involved. Unlike other industries or sectors, an error in healthcare can directly (physically) harm people. The increased stakes mean there needs to be strict regulatory oversight. The Government should assess changing existing healthcare laws and regulations to specifically address AI-related issues – particularly things like clinical accountability, patient consent, and data security.

 

7.      How does the use of AI differ in healthcare settings compared to general or other sectors such as finance, education, etc.?

In healthcare, AI may influence or direct clinical decisions that could directly impact human physical well-being, requiring far higher standards of accuracy and reliability than sectors like finance or education. Mistakes in healthcare AI could lead to physical harm or even death, whereas mistakes in other sectors are often financial or reputational. This means that an use of AI should include stringent testing, certification, and regulatory scrutiny.

 

8.      Should there be an Australian body specifically dedicated to overseeing AI in health care?

Yes, a dedicated federal body, similar to / or perhaps reporting to, the Therapeutic Goods Administration (TGA) could be established to oversee regulation of AI in healthcare. This body would be tasked with ensuring that AI tools meet required safety, accuracy, and ethical standards. Additionally, it could also serve to be a liaison between developers, healthcare providers, and policymakers.

 

9.      Are there any specific changes to existing health care laws that would address AI-related harms or help AI to be used safely?

Again, without being an expert in the existing health care laws; I would have to assume that there is an opportunity somewhere akin to how we govern medical devices. Perhaps these could be expanded to explicitly include AI-driven technologies. There should also be updates to legislation that handles data privacy and security (I think this would be The Privacy Act?).

 

10.  Which international approaches should we consider, if any, that are specific to health care?

Internationally, I believe that the EU’s General Data Protection Regulation (GDPR) and possibly their Artificial Intelligence Act would be useful to review as they prioritize patient data protection and ethical AI use. Australia could consider adopting similar standards to ensure AI technologies are safe, transparent, and effective, while also factoring in patient privacy.

11.  Should humans be able to overrule a finding or decision made by AI?

Yes, human healthcare professionals should always retain the ability to overrule AI decisions. AI should only every be used to ASSIST rather than replace human judgment. This is essential in healthcare since these often relate to clinical decisions where clinicians need to be able to be able to think critically, factor in context, and have empathy.

 

12.  Should there always be a person or “human in the loop” to make decisions or deliver a healthcare service? Are there any circumstances in which it would be acceptable to have fully automated health or care decisions made by an AI product?

There should almost always be human oversight and involvement. Humans must always remain “in the loop” for critical elements like diagnosis or treatment planning. There may be lower risk, or more mundane  areas in administrative or clerical tasks that you may be able to fully automate (as long as there are sufficient safety measures in place).

 

13.  Should errors made by AI be reported? If yes, how should they be reported?

Yes – all errors made by AI should be documented and transparently reported. A national or federal reporting system could be created that links into the proposed governing body from question 8. These errors would need to be logged, data analysed, with the aim of improving future AI performance and safety.

 

14.  Should there be transparency about when AI is involved in health or care, and should consent be requested from the consumer or healthcare professional?

Use of AI should always be disclosed and both patients and healthcare professionals should be informed/aware of its use. Patients should provide informed consent, particularly if the AI directly influences clinical decisions.

 

15.  Generative AI may be developed for general use, yet used in health care. Should generative AI have any special treatment, regulatory or otherwise?

I believe that in any areas where there is an update or section relating to AI – that there should be some clause or section that explicitly covers Generative AI. The major concern is that because it is adaptive and can be influenced by bad data/information which could result in unsafe or incorrect medical advice.

 

16.  What protections are needed for patient data used or generated by AI that are different for health care?

Healthcare data is highly sensitive and security is of the utmost importance. AI systems will need to ensure that since they are accessing this highly sensitive data that they should also adhere to the highest standards of data encryption, anonymization, and other prudent modern security methods. Furthermore, regulations should ensure that AI developers/services/companies cannot misuse or sell patient data without explicit consent, oversight, and transparency. Any disclosures or requests to access patient information should also be reviewed or alerted to the proposed governing body (Q8).

 

17.  Is it acceptable for developers of AI products to use patient data to develop their products or to sell patient data collected from use of AI?

It is absolutely unacceptable for any developer/company to sell patient data. Any data-sharing arrangements should be fully transparent, and all stakeholders alerted/notified when it occurs, and should comply with strict privacy laws.

 

18.  Should your healthcare information be kept in Australia? If yes, would your view change if this reduced ability to access advances in AI made overseas?

This is a challenging question – I believe that for the most part all efforts to retain healthcare information and data should be made. However, given the nature of technology and advancements – there should also be reasonable understanding that in some cases data is able to be sent or accessible by offshore. Overall, all options should make certain that patient privacy is protected.

 

19.  Are there any specific safety considerations that have not been raised elsewhere?

One safety concern that hasn’t been explored is the idea of algorithmic bias. There is a potential for AI systems to be trained or access biased/skewed datasets. Steps would need to be taken to ensure that AI systems are trained/based on diverse, representative data is crucial to avoid unintended harm.

Spicy Soba Noodles

This recipe is so quick and simple that it’s a go to option when we feel like having something yum for dinner - but don’t have the energy to cook something complicated. Also, despite me making this over a dozen times, it’s only just dawned on me that this is unintentionally a Vegan dish.


INGREDIENTS:

  • 270g dried soba noodles (1 packet is 270g).

  • 4 tablespoons soy sauce

  • 2 tsp chilli bean sauce

  • 2 tsp minced fresh garlic (5-6 cloves)

  • 1 tsp sesame oil

  • 6 cups watercress (1-2 bunches), cut into 3-4 cm long pieces

  • 2 tbsp peanut/rice oil

  • Toasted Sesame seeds (garnish)

  • Optional, 1-2 Bullet chilli, chopped (to taste)


METHOD:

  1. Bring a large pot of water to boil over high heat. Add soba noodles (270g) and cook for 3-4 minutes (or whatever the package instructions are for stir fry).

  2. Whilst that is boiling, in a small bowl stir together the soy sauce (4 tbsp), chilli bean sauce (2 tsp), garlic mince and sesame oil (1 tsp). You can optionally add in 1 bullet chilli here, what I tend to do is cut it up, and add half a chilli to start with, and add to taste / heat tolerance of people eating it.

  3. Drain the boiled noodles in a colander and set aside to be used in a moment.

  4. In a large pot/hotpot, heat the peanut/rice oil over a medium-high heat for a minute.

  5. Add Watercress (be careful, the water from washing the watercress might cause it to spit), heat/cook for 1 -2 minutes until wilted (note: I cook these using kitchen tongs).

  6. Add soba noodles and sauce, and combine over medium heat.

  7. Season to taste with additional soy (be careful with how much you add, I recommend doing it in 1 tbsp amounts, mixing, and taste).

  8. Turn off heat, and serve with a garnish of toasted sesame seeds.

Parmesan Pumpkin Gratin

Be warned, this recipe may ruin how you enjoy pumpkin after tasting it. This is technically a side dish, but every time we have it I’m always wanting to eat more of it.


INGREDIENTS:

  • Butternut Pumpkin, 1 (~1kg)

  • Butter, 1 cup

  • Garlic, 2 cloves, finely chopped

  • Panko Bread Crumbs, 1/4 cup

  • Parmesan cheese, 1/3 cup, grated

  • Fresh Parsley, 1/4 cup, chopped

  • Salt, 1/4 tsp

  • Pepper, 1/8 tsp


METHOD:

  1. Heat oven to 190 degree C (375F). Spray a 30x20 glass baking dish with cooking spray.

  2. Peel, halve lengthwise, and seed the pumpkin. Cut into 1cm thick slices.

  3. Arrange slices overlapping slightly in bottom of baking dish.

  4. In a medium saucepan, melt butter (1 cup) over medium heat.

  5. Reduce heat to low, add Garlic (2 cloves worth); cook for 2-3 minutes, stirring frequently until garlic is soft. (Do not let butter brown).

  6. In a small bowl, mix panko bread crumbs (1/4 cup), parmesan cheese (1/3 cup), and 1 tablespoon of the butter-garlic mixture.

  7. Brush the pumpkin with remaining butter-garlic mixture. Sprinkle on salt (1/4 tsp), pepper (1/8 tsp), and the bread crumb mixture.

  8. Bake uncovered for 30-40 min (or until pumpkin is tender when poked with fork). Increase oven to 220 C (425F) for 5-10 more minutes, or until lightly browned.

  9. Remove from oven, and sprinkle with parsley before serving.

Sue's Awesome Banana Muffins

Quite a lot of the recipes I make and share come from my wife (Sue). When she made these quick, easy, and mostly healthy Banana Muffins the other day I was blown away. Not only were they delicious, but a fun activity to do with Zach.

IMG_8285.jpg

Ingredients:

  • 3 large ripe bananas

  • 3/4 cup white sugar

  • 1 egg

  • 1/3 cup oil vegetable oil is best

  • 1 1/2 cups all purpose flour

  • 1 tsp baking soda (bi carb soda)

  • 1 tsp baking powder

  • 1/2 tsp salt


Optional Ingredients:

  • Chocolate Chips

  • Blueberries

  • Oats (Steel Cut)

METHOD:

  1. Preheat your oven to 180 degrees C and line your muffin tin with 12 paper muffin cups.

  2. In a large mixing bowl, mash the bananas with a fork until no large pieces remain.     

  3. Add the sugar, egg and oil and mix with a wooden spoon until everything is incorporated.

  4. Measure the flour, baking powder, baking soda and salt into a separate mixing bowl and stir them together with a fork. Once they’re mixed together, dump the dry ingredients into the wet ingredients.

  5. Using a wooden spoon, carefully mix the wet and the dry ingredients together. The danger here is over-mixing which will result in dense, flat and dry muffins. The best technique for mixing is to scoop underneath the mixture and pull up gently instead of stirring around in a circle (like you’d stir your coffee, for example). Continue mixing this way just until the dry ingredients have been incorporated. It’s fine if there are a few small streaks of flour in the batter; it’s the large pockets of flour you want to make sure are incorporated.

  6. Spoon the batter into 12 lined muffin cups. Try your best to ensure you fill the cups evenly. This will ensure each of the muffins is finished baking at the same time (you don’t want some over-baked and some raw in the middle!)

  7. OPTIONAL: Add in Chocolate Chips / Blueberries to filled muffin cups, stir in/mix with toothpick.

  8. OPTIONAL: Coat / top muffins with sprinkle of oats.

  9. Bake the muffins in the oven at 180 degrees C (350F) for about 16-18min (it could be 22-25 min depending on your oven, but check around the 18min mark) or until they are golden brown.

  10. Let them cool in the tins for about 5 minutes and then turn them out of the tins to let them cool completely on a cooling rack. Or, enjoy one warm from the oven slathered in butter.


Notes:

You can store the muffins in an air tight container for about 4 days, but just make sure they are fully cooled before you store them.

Confessions from a Coffee Addict - Factors that influence where I get my coffee

Do you ever stop to think about the factors involved in something you do everyday? I’m a self-diagnosed coffee addict and it’s taken me far too long to come up with a list.

coffee1.jpg

When Sean posed the question "what do you look for in a new local coffee establishment" I started brewing my thoughts on this.

coffee_sean.PNG

As fate would have it, I have recently moved and had to search for my new local.

The factors that play into my deciding where I get my coffee are (in order of most important to least):

Great Coffee

This is most oblivious and most important element - Is the coffee good? Nothing will redeem an average or poor coffee. I don't care about the rest of the items on this list, if you can't pass the basic hurdle of a coffee that makes me smile - it's not likely I'll be back. What goes into a good/great coffee? Beans, Machine, Barista. These are what I think are the core elements that make a great coffee.

Speed of making Coffee

The second element that will often make me decide if I'll go to a cafe or not is how long the baristas take to make a coffee. I'm going to sound like a wanker for this, but if your cafe makes coffees one at a time, and/or gets overwhelmed when 3 people have ordered - then I'm usually going to think twice about going there. Good baristas know how to efficiently churn our coffees, and good cafes know that during rush times it'll pay to have one staff working the beans/coffee and another doing milk & completing orders. I've noticed that the best cafes in Sydney have two staff making coffees when it's peak hour.

Almond Milk brand

This seems trivial at first, but my wife will only have Milk Lab almond milk. Almond Breeze is too sweet for her. This plays a deciding factor because I'm never going to make two trips to different cafes if I'm grabbing both of us coffee.

Perhaps it's a little jaded to say - but I find that cafes that take their coffee seriously stock Milk Lab.

Ability to order via App?

This'll be a bit of contentious view, but I LOVE when a cafe has online ordering via HEY YOU or some other mechanism. There are days where I don't have the time to hang around waiting for a possible delay in my coffee coming out - and in those mornings, when minutes matter, I desperately need a coffee to start my day. Ordering ahead means I can swoop in, grab my coffee, and race off. I'll preference an APP cafe over a non-app cafe often.

Great Service

Friendly and attentive staff are always a draw. It doesn't have to be complex, a simple smile and polite manners (basic customer service) are easy wins. Cafes that stand out to me often have staff that know my name, & usual order.

How busy they are

Whenever you are looking in a new area I gravitate to where the queues and patrons are. Granted, this might be a symptom of a slow barista, but often busy/popular cafes are packed for a good reason (it’s good).

Appearance/Tidiness of cafe

Not as overly important, but plays a factor. If the coffee area is a disaster, looks chaotic, then I'm going to question what’s going on.

Reviews/Ratings

If I'm completely out of my element or in a brand new place, I'll resort to checking online reviews (google review, bean hunter, yelp/zomato maybe).

Remote Work Friendly (Powerpoints/Wifi).

As a remote worker/someone who works from the road a lot, I really appreciate when a cafe has power outlets, enough space to allow for people to work. I'm always aware of amount of seating and how busy the cafe is, you never sit at a spot for too long if it's packed or there are customers that will likely order a larger meal. I always ask the staff when I'm ordering a coffee if it's ok to work. Free Wifi is a bonus.

I’d be curious to see if any of these resonated with other people.
