The regulatory atmosphere on the US Meals and Drug Administration (“FDA”) has an amazing impression on how firms function, and consequently information on that atmosphere might be fairly helpful in enterprise planning. Consistent with the theme of those posts of unpacking averages, it’s vital to drill down sufficiently to get a way of the regulatory atmosphere during which a selected firm operates quite than depend on extra world averages for all the medical machine business. However, getting too particular within the information and specializing in one specific product class can stop an organization from seeing the forest for the bushes.
Just lately, I used to be requested by firms within the subject of digital medical units used within the care of individuals with diabetes to assist them assess tendencies within the regulatory atmosphere. To do this, I made a decision to create an index that will seize the regulatory atmosphere for medium danger digital diabetes units, making an attempt to keep away from getting too particular but in addition avoiding world information on all medical units. On this sense, the index is like some other index, such because the Normal & Poor 500, which is used to evaluate the financial efficiency of the most important firms when it comes to capitalization. My plan was to first outline an index of product codes for these medium danger digital diabetes merchandise, then use that index to evaluate the regulatory atmosphere in each premarket and postmarket regulatory necessities.
Product codes are the language of FDA regulation. Each medical machine FDA regulates is positioned right into a product code. If there isn’t a product code for a brand new machine, FDA has to create one, typically by way of the de novo course of. Roughly 2100 machine classifications discovered within the rules are additional subdivided into over 6700 product codes, and they’re organized roughly by medical specialties corresponding to anesthesiology, medical chemistry and basic surgical procedure.
Whereas medical specialties might be helpful groupings, every of them can also be fairly broad and none of them are illness particular. Because of this, if your organization is targeted, for instance, on merchandise for diabetes, the diagnostic codes may be in a single or two completely different medical specialties whereas the therapeutic merchandise may be in but a unique medical specialty grouping. Extra problematic, in case your focus is diabetes, these medical specialties will likely be far too overbroad to be helpful for assessing the related regulatory atmosphere.
For prior posts, I created a database of the 510(okay) summaries submitted to FDA. Utilizing that database, I started by trying to find the phrase ‘diabetes,’ but in addition phrases and phrases like ‘insulin’, ‘diabetic retinopathy’, ‘diabetic nephropathy’, and ‘diabetic neuropathy’. My search additionally included extra unique phrases simply to ensure that it was complete, utilizing the PubMed MeSH (medical topic headings) framework to establish synonyms and associated situations.
My focus was on digital diabetes merchandise, so I then individually looked for the phrase ‘software program.’ I reasoned that it was extremely probably that any digital product would no less than point out the phrase ‘software program’ within the abstract, though technically it’s additionally attainable that somebody may need written that ‘our product contains no software program.’ Provided that the development is towards digital, it appeared unlikely to me that very many submissions would come with the phrase “no software program” as if to brag about being decrease tech, however it’s attainable.
On the finish, I selected the product codes that have been on the intersection of the 2 completely different searches. That course of produced an inventory of roughly 50 product codes.
I needed to focus the listing in order to not embrace merchandise that have been solely tangentially associated to digital units for diabetes, so I took two extra steps. First, I divided the variety of submissions in every product code that point out diabetes by the full variety of submissions. I reasoned that this could give me a proportion of submissions in a given product code that talked about diabetes, which might be an excellent bellwether for the relevance of the product code for my goal. Second, I consulted some medical specialists to ask them what they might contemplate out of my listing to be probably the most related product codes for this goal. On this mission, for instance, many wound therapy merchandise talked about diabetes, however the specialists didn’t contemplate wound therapy to be really a diabetes product.
On the finish of this course of, I got here up with an index primarily based on the next 30 product codes as representing medium danger digital diabetes medical units.
I used to be centered on medium danger, as a result of fairly frankly there are giant variations in regulatory environments between class I, class II and sophistication III medical units (starting from merchandise which are exempt from premarket assessment to those who require premarket approval), and the folks with whom I used to be talking have been largely within the medium danger enterprise.
Having outlined my index by product codes, that index then allowed me to see how that class performs broadly in nearly any dimension for which FDA produces information. For instance, I needed to first see how these medium danger digital diabetes medical units truthful when it comes to FDA assessment instances.

The black strains are the 30 digital diabetes product codes. What appears to be like like a blue space is definitely 6600 vertical blue strains representing the typical assessment time inside every product code sorted from shortest to longest. The shortest common assessment time for a single product code is simply over 50 days, and the longest common assessment time for a selected product code is over 500 days.
The digital diabetes merchandise are clustered towards the lengthy assessment finish. The common is marked by the dotted line, and the digital diabetes merchandise are all nicely above common. And you’ll see why I do that, as a result of there actually isn’t any such factor as a typical medical machine assessment time. As an alternative, they differ extensively relying on the product codes.
Having seen this, I used to be excited by whether or not this sample adjustments over time. The chart above was merely the averages over about 12 years’ value of knowledge (2010-2022). Within the chart under, I broke it down by 12 months.

These are calendar years, and I did the evaluation in October 2022, in order that 12 months is a partial 12 months.
The colours require a little bit of clarification as a result of I solely used two colours. I used pink to depict the digital diabetes index assessment instances, and I picked blue to characterize the averages for all medical units. This makes it straightforward to see that in all however two years, the pink assessment instances – the digital diabetes assessment instances – exceeded the typical for all medical units sometimes by a large margin. However in two years – 2019 and 2020 – the averages for all medical units exceeded the assessment instances for digital diabetes merchandise. Truthfully, I do not know why 2019 and 2020 have been completely different from the general development.
Trying on the information, naturally I questioned why FDA was so sluggish in its assessment of digital diabetes merchandise compared to the general averages. To search for a solution, I studied the information on the postmarket expertise for these merchandise. Specifically, I examined the variety of medical machine reviews filed for the listed digital diabetes product codes versus all the opposite product codes.
Right here, to make the visualization extra readable, I solely centered on the 20 worst medical machine product codes, the place “worst” means these having the best variety of medical machine reviews (“MDRs”) filed in a given 12 months. Thus, these are those that FDA has the best concern with regard to product security and effectiveness. I picked 2021 as a result of that was the latest full 12 months of knowledge that I had.

You’ll discover that the magnitude of the variety of MDRs falls quickly by product code. The black bars are the product codes from the digital diabetes index. There are 5 product codes among the many prime 20 which are included within the digital diabetes house.
I don’t need to take care of this complicated problem too simplistically. It’s past the scope of this put up to investigate why these information are the best way they’re. I believe most individuals acknowledge that folks with diabetes have many challenges in that a lot of them are aged and have restricted imaginative and prescient and handbook dexterity, making it troublesome for them to make use of medical units of assorted kinds. Additionally, clearly, the sheer variety of folks with diabetes implies that there are lots of of those merchandise in circulation at anyone time.
Whereas I don’t imply to dismiss the necessity for a extra nuanced evaluation of the information, I might merely level out from a giant image perspective that these information are what FDA appears to be like at within the postmarket expertise, and this expertise in all probability contributes to FDA’s conservatism in how they assessment new product submissions on this class.
Typically it’s vital when wanting on the information to not have a look at the medical machine business as a complete as if it’s homogenous, nor to zero in too intently on particular person merchandise and product codes when making an attempt to discern FDA tendencies. Creating an index is a method that an organization can observe the related regulatory atmosphere during which it operates. And that monitoring can produce insights about what the business usually must do at a excessive stage and what they will anticipate from FDA regulation.
