Freestyle Libre

FreeStyle LibreLink: First Impressions!

8 Comments

I must admit that I couldn’t get too excited at the news of FreeStyle LibreLink hitting our shoes Down Under. However I was really blown away by the response to my vlog last week, which suggests that perhaps I am in the minority on this new smartphone app.

FreeStyle LibreLink is a smartphone app that can either complement or replace the fundamental role of a FreeStyle Libre reader. So if you are thinking about trialling or getting started with a FreeStyle Libre system, you will no longer need to invest in a $95 reader. I also thought that LibreLink may be advantageous to parents or loved ones, who could have their own access to the data provided they scan the sensor with their respective devices (devices don’t share data).

Abbott told us that while LibreLink was originally due in August, they have fast tracked the launch as a show of their commitment to get their technology into the hands of as many people as possible.

The FreeStyle Libre system utilises Near Field Communication (NFC) technology in order to scan the sensor and obtain a blood glucose reading. In order to use the FreeStyle LibreLink app, your phone must have these same NFC capabilities as the FreeStyle Libre system, and this is the reason for limitations on compatible phone models.

So, blame Apple. Or Samsung. Or whoever else you feel like blaming.

Apple users will need an iPhone 7 or higher, running on iOS 11 or higher. Android users will need a phone with NFC, running on Android 5.0 (Lollipop) or higher.

If you wish to use your reader in conjunction with the LibreLink app, you must activate a new FreeStyle Libre sensor with your reader, followed by the LibreLink app during the 60 minute warmup period. If you do not activate with both devices during the warmup period, then you will only be able to read data with the one device you activated with.

Why can LibreLink only be used with a new sensor, and not an existing one? I am told this is purely for security reasons, otherwise I could theoretically approach anyone wearing a sensor and scan it.

My loaner iPhone seemed to scan my FreeStyle Libre sensor just as well as my reader did. A reading is best taken by pointing the top end of your iPhone, where your ear rests, over the sensor.

One noteworthy feature is the text to voice, which will voice your blood glucose level and trend following a scan. This may prove useful when you’re in bed and don’t want to open your eyes, or if you’re wanting to interrupt someone else’s presentation and show off your reading of 6.6 and steady to the rest of the group (sorry, Kim!).

I also think that the app will be really valuable for accessing blood glucose reports without the need to upload to a computer. I must admit I can’t remember the last time I uploaded my pump or my meters to the computer. In the whole scope of managing diabetes, little tasks like these often slip and features like this really do make a big difference.

LibreLink does not have the capability to transmit blood glucose data to another device. Nor can data be shared between a phone and a reader. You know how you can click on that little forward button when browsing your iPhone to share a link or a photo? That’s basically how you can share things like screenshots or reports from inside the LibreLink app with others.

Everything else that you’re used to seeing in the reader is there, with a bit of an expanded view.

      

Also on the horizon is Libreview, a cloud based software designed as a companion to LibreLink that provides a way to share data with healthcare professionals.

I don’t have any plans to upgrade my old iPhone 6 anytime soon to use the LibreLink at home. I’m also not sure that I view carrying my Libre reader around as a hassle. Having my iPhone on me all the time can be equally distracting. Another reservation I have is the increased demand placed on my iPhone’s resources from the introduction of two new mobile apps in the space of a week (YpsoPump app and LibreLink).

That being said, I have definitely underestimated LibreLink. It’s fantastic that FreeStyle Libre users will have more ways to access and engage with their blood glucose data. More choice for people with diabetes is always a good thing.

The FreeStyle LibreLink app launches in Australia tomorrow, and is available as a free download from your Apple or Google Play store on a compatible device.

Disclosures: Abbott Diabetes Care covered my travel and accommodation costs to attend DX2Sydney. I was fed and watered across the duration of the event. I was also provided with a FreeStyle Libre sensor and a loaner phone if I wished to trial the FreeStyle LibreLink app during the event.

DX2Sydney 2018

1 Comment

I’m at home today, nursing a sore throat and a cold which was most likely picked up at the end of Abbott’s third annual DX blogger event in Sydney earlier this week.

DX – which stands for Diabetes Exchange – is now into its third year Down Under. Abbott was the first company in the Australian diabetes space, that I’m aware of, who began talking to consumers when the FreeStyle Libre was launched in May 2016. From there we have seen other companies follow suit, providing more platforms for the lived experience to be heard (no doubt with a little push from some of my fellow diabetes advocates).

It was nice to be reminded of my first encounter with this special group of advocates back in May 2016, and how much my voice has grown and evolved since then. This group of oversharers have become somewhat of a close knit family over a short space of time, with a few new faces entering the fold every year.

While we were primarily convened ahead of the launch of the LibreLink app in Australia on June 5, we also had the opportunity to present some feedback to Abbott on the FreeStyle Libre.

My question to both Diabetes Australia CEO Greg Johnson and the Abbott team was around whether partial subsidies for Flash Glucose Monitoring in the form of co payments would be an option, as seen with our test strips and pump consumables. 

I have only ever seen full reimbursement noted by Abbott in official communications, and wondered whether more of a focus on partial reimbursement would help get the FreeStyle Libre subsidised sooner. Bionic Wookiee David also rightly corrected Abbott’s term of ‘reimbursement’ with ‘subsidy,’ given that consumers won’t be reimbursed for anything should the product receive federal government funding.

Professor Johnson told us that co payments were certainly an option as we often see through Medicare, and that Diabetes Australia were surprised by the Federal Government’s last election promise of fully subsidised CGMs for people under the age of 21.

Abbott’s Regional Director Peter Chalikias told us that reimbursement decisions rested with the Federal Government and the Department of Health, with the company’s priority to get the FreeStyle Libre into the hands of as many people as possible.

Jessica Shi, Abbott’s QA & RA Manager, must have been reading my mind when she addressed the need for call centre staff to better gauge the level of expertise from the person with diabetes reporting an issue over the phone. Nothing is more frustrating than receiving a basic lecture on what interstitial fluid is!

Once again, I cannot express how important it is to get in contact with the call centre should you have any issues with the product. Some of Abbott’s current priorities based on user feedback are cost, adhesion and accuracy. Cost reductions that Abbott are able to make in the manufacture of the FreeStyle Libre get put back into research and development that will potentially help to address these user issues. 

Does that mean we’re likely to see the product shift towards something that more closely resembles a Continuous Glucose Monitor? Would Abbott not prefer customers to be using a more trusted, in house data sharing solution, rather than third party products such as the BluCon Nightrider?

At this stage, it’s understandably not a priority. I personally wouldn’t want to see the FreeStyle Libre change. Providing consumers with choice is important, and the product in its current iteration means that more people will be able to access Continuous Glucose Data.

“Do you feel that you have had any input into the FreeStyle Libre by attending these events?”

My answer to this question I was posed last week was simple. None. 

I don’t have a technical mind. I don’t know anything about all of the research, development and regulatory compliance that goes into making a medical device as such. 

Abbott also know that they don’t need me, or any of the other bloggers in the room to sell their hugely successful product. Yet their continued respect and commitment to hearing what’s important to (highly privileged) people with diabetes through these DX events, is where I hope I am making a very small difference.

Any company operating in the diabetes space that chooses to engage with people with diabetes is a good thing.

It’s been a pleasure to be part of the DX Family.

Disclosures: Abbott covered my travel and accommodation costs to attend the DX event in Sydney. I was also fed and watered through the duration of the event, and received a goodie bag which contained a FreeStyle Libre sensor. There was no expectation that I would blog about anything covered at DX2 Sydney. My opinions and my time, including the annual leave I took from work to be here, are as always my own.

FreeStyle LibreLink App Launches in Australia!

I’m in Sydney over the next two days attending Abbott’s third annual DX event, which brings together a group of Aussie diabetes bloggers.

Abbott are launching the FreeStyle LibreLink app in Australia on June 5, and this can either complement or replace the fundamental role of a FreeStyle Libre reader. Abbott are letting me road test the LibreLink app for 24 hours, so hit the play button below to see how it all works.

I’ll be sharing further insights on LibreLink and the Ypsopump on Instagram, so send me a follow request if you’re not following me already!

Insulin Gone Bad.

3 Comments

I couldn’t help but notice the reading of 14.1. Is that high? My friend asked me from across the table as I was demonstrating my FreeStyle Libre.

Yeah, I obviously haven’t given enough insulin for the banana bread, I replied, pulling my pump out of my pocket and bolusing for another 30 grams of carbs ever so casually.

I had already bolused a very generous 60 grams of carbs for the slice of banana bread and iced coffee I had ordered at the local cafe, but I wasn’t overly surprised to see the upward trend arrow on my Libre.

My blood sugar was still skyrocketing by the time I arrived home an hour later, with my Libre clocking in at a lovely 17.4. I bolused for another 10g of carbs, bringing the total for my mid morning coffee catch up to an overly generous 100g of carbs. I was certain that all of this insulin was bound to kick in any minute now.

After another hour had passed and my Libre clocked in at 25, I had figured that banana bread was the devil. After a prick of the finger came in at 20.4, I ignored all insulin I had on board and gave a full 4 unit correction. I also set a temporary basal rate of 100% to help get things moving in the right direction.

After a bucketful of insulin, my blood sugars slowly but surely began moving in the right direction over the course of the afternoon.

When dinner time rolled around and I was back in range, I bolused for the 50 grams of carbs on my plate. I drank a glass of water. I stepped outside and turned the sprinklers on. I washed some strawberries that I planned on having post dinner. I drank yet another glass of water. I stepped outside again, and switched the reticulation off. After distracting myself for a good 20 minutes or so for the bolus to kick in, I finally tucked into my dinner with the hope of avoiding another blood sugar rollercoaster.

Fast forward to me in front of the television 2 hours later, and my blood sugar clocked in at 16.1 with an upward trend arrow on my Libre.

I scrolled back through my pump history, noting that my last prime was four and a half days ago. As I swapped out the infusion site, my brain began to cotton on to other moments of particularly difficult-to-manage post meal blood sugars in recent days.

The lone milky coffee that sent my blood sugar upwards of 10. The hot cross bun that I’d carefully pre bolused for, but landed me close to 20. Rising blood sugars, despite a long walk fuelled by 10g of chocolate beforehand. Even a pasta meal had been extremely difficult to manage.

As I connected all of these recent occurrences together, I eventually recalled another occurrence of skyrocketing levels when my insulin had spoiled 2 years ago.

My insulin had spoiled! There was my answer! 

So, maybe Banana bread wasn’t the devil after all.

Which Meter Do I Trust?

6 Comments

One of the more “fun” pieces I recently had the opportunity to cover for Diabetes Daily was meter accuracy.

“To be fair, all blood glucose meters will only be accurate to the nearest 1 mmol/L (18 mg/dL) of a laboratory result. Which explains why two simultaneous blood glucose checks will likely produce two different results.

Most blood glucose meters must have a mean absolute relative difference (MARD) within 15 to 20 percent of laboratory results. This standard deems these devices a reliable indicator of blood glucose levels and safe to dose insulin from.

Which blood glucose meter can I trust? I conducted an experiment of sorts at home comparing all of the blood glucose monitoring devices that I currently use.”

You can see the results of my little experiment for yourself in the full column at Diabetes Daily here.
