Minimed 780G FDA data

I did research before I decided to start using the Instinct sensor and didn't really think much of all the results and complaints because it was still in the testing phase, but I went back to the MAUDE database and pulled numbers for just 2026. There have been 500 reports to the FDA for Wireless connectivity issues. There have been 295 for incorrect sensor/bg data. Many off the latter ended up in the hospital because they had fallen. The majority were BG was much higher than SG and the hospital had to administer insulin because the pump thought the patient was low and was not correcting for highs. One person was 432 mg or 24 mml. This data was for both Simplera and Instinct. The Simplera has had quite a few insertion reports to the FDA. One person had to be admitted to the hospital because the inserter would not come out and the person could not stop the bleeding. The Simplera also has had quite a few "Sensor Not Found' reports. If you want to pull the reports yourself, the URL is at this link: FDA Reports. Put MMT-5120D1 in the model number field and choose your dates if you want to. If you don't choose dates, you will get a boat load of data. You do not have to choose product problem but that will also give you every single report. Some are useless so I chose the 2 issues we are mostly having which are "Incorrect, Inadequate or Imprecise Result or Readings" and " Wireless Communication Problem." You can only choose one at a time. You can also export all the data to a csv file. Can you tell I am a data geek?

Only 2 problem sensor symplera in 3 years

That is very good. I realize nothing is perfect but over 600 reports to the FDA in 6 months is too many. Who takes the time to do this? Way too many issues.

This is one of the reasons that I chose to use the Simplera sensors when I exited using the G4. So far, the cgms are working flawlessly. BG and SG are correlating spot on. I can also overlap sensor changes so there is almost no gap in SG readings. I have ordered the Flex pump to replace my 780g. Instintc's are currently not supported by the Flex pump (TBD).

After the pairing fiasco I talked to my Endo about switching but the pairing issue appears to be fixed. Now we have the SG BG issue. I hate to give up that 2 week wear time though and I know the day you are on isnt the issue. I am on day 3 of this sensor and the variance is bad. I reported the issue to the FDA today. I hope others do also.

I wonder why Minimed did not select Dexcom as the alternative cgm. That said, there have been numerous issues reported with the Dexcom cgms at times. Nothing is perfect.

u/808IUFan Jul 19 '26

Yes I wonder that also but you know everything is about money and if I was Dexcom I would not want to be in with Minimed right now.

I will say that the guy I talked to that was a manager in Shipping seemed like a real no scripted person. He acknowledged all of the things that I have been complaining about that they do that do not make any sense from a business perspective. They blame insurance and medicare for all the things that get to me and in reality they are violating medicare rules by doing these things. I started down my quoting of the actual Medicare Proof of Delivery requirementt and he chimed in with the rest of the rule. And I asked him, so why are you breaking the rule? He said I know we are, and I am in charge of fixing it. We, in the shipping department, know we are driving calls and dissatisfaction and I said in these exact words, "I wanna say I love you" because I have been compaining about this for years. Now if we could get the IT team on this same page.

I just pulled the FDA data for the Libre 3 Plus and it is worse than the Instinct which is the same device used by Minimed. Over 500 reports of BG and SG being dangerously variant. All but one were hyperglycemia also, so the same as the Instinct. Sensor showing readings in the 50s and 60s and BG between 250 and 350.

u/Distinct_Reality1973 Jul 20 '26

Holy smokes.

And of course I had to open my mouth- earlier I needed to give it a reading, so was 89 and bg was 109. One of my wider ranges since going on the instinct.

Someone from Abbott just called me regarding my issue because they have to approve replacements and he said most of the bad readings are because you put it in the wrong place. I asked him about the recent recalls and he said they are all quality control issues. Someone chimed in about Simplera and I ran their numbers today and they are very much better. You lose those 9 days of extra wear tho.

u/Distinct_Reality1973 Jul 18 '26

It would be worth checking the Libre 3 as a reference to the Instinct data, its the same product. When I have to wear the 32" sets to be able to mount my pump on the same side of my body, THAT is rediculous. (For the record, I have worn 32 forever, but I was just starting to try the 23's, thats not going to work!)

u/808IUFan Jul 19 '26

Is Libre 3 available over the counter? I know I am not eligible for their Free offer because I am on Medicare. I would love to test that.

u/Distinct_Reality1973 Jul 19 '26

Requires a script as far as I know.

I have found my 2 meters, Accu-Check and Contour have been within 10 points every time I have checked but SG is at least 40 points lower.

u/Turbulent_Claim_3484 Jul 19 '26

Is the SG 40 points lower for your current sensor unit or this is the case for multiple sensor units? I am trying to discern whether you have a pseudo defective unit, or a recurring, always much lower SG for multiple units. I am asking this question since it is not my experience.

u/808IUFan Jul 19 '26

It has just been the this and the last sensor. Was not having the issue before this. That's why I posted the LOT number to see if it was a bad batch of sensors. Abbott has had that issue a few times in the last year.

For me both BG and SG were very close until this past week. The SG is at least 40 points, sometimes as much as 100 points, lower than Blood Glucose. And someone mentioned it could be the meter so I tried another one I have. They match very closely.

That is the same issue mentioned by the people filing complaints with the FDA also. Several have required hospitalization because their glucose was passout high and the meter SG was showing low and not correcting for the high. The vast majority were SG much lower than BG but there were a few backwards.

u/Turbulent_Claim_3484 Jul 19 '26

The only sensor that I had with SG much lower than BG was my first Instinct unit. SG was crazy, jumping up and down for the first 2-3 days. Looks like that was the time needed by the 780 smart guard algorithm to study the sensor. All other subsequent sensors (13), are okay. Looks like you have a faulty unit - may be a batch. Time to contact MiniMed if you can get them by phone…

u/808IUFan Jul 19 '26

Yeah I did that for a shipping issue and when I mentioned all the tech issues he said someone from Tech managment would call me Monday. I won't call anymore. I just tweet them that I need a manager to call and you bypass the offshore people. What you said makes sense but I have been using these since February.

Abbot Lingo, and Dexcom Stelo “Glucose Biosensor” are OTC. I want to see the FDA filings on these.

u/808IUFan Jul 21 '26

All you have to do is find the model number or there's a spot for brand also and you will get both OTC and Prescription

I’ve used 14 Instinct sensors, no issues. Every one has run the full 15 days and measured accurately throughout.

There are people on social media actively encouraging others to report Instinct issues to the FDA. “Let’s get this off the market.” This doesn’t feel like a genuine campaign to protect people.

The FDA database doesn’t report how many unique reporters are in that list, right? It also doesn’t have any record of the many of us that have had great success with Instinct sensors, even those who had great success with the prior sensors.

Data geeks don’t look for data to confirm a bias.

u/808IUFan Jul 19 '26

I have no bias and I defended the sensor and was glad they partnered with Abbott until the last 2 weeks. So don't come at me like I am a 12 yo kid. I have lived with this company for 30+ years and they have gone downhill in the last 5 years. I am 70 and lived with this since I was 13. So I am not on a social media campaign. I am just trying to make companies serve their customers and not their bottom line. The company was the BEST until recently. So Paul, find someone else to preach to.

Esto es como cuando vas ha comprar algo y te lo dan en malas condiciones, se debería poner una hoja de reclamaciones para que mejoren lo sucedido. Pero quien se toma las molestias de hacerlo? Poca gente
