Update # 2 on "8." MAUDE Database

I've previously written (here and here) about an error in the FDA medical device adverse events database known as MAUDE. The error prevents the database from reporting patient outcomes (death, hospitalization, etc.).

I received correspondence from someone at the FDA last week indicating that they may have found a fix (see screenshot of email).

However, so far, they have not implemented the fix. You can see this in two ways:

First, if you download the patient outcome file from the FDA website and open it up, you see a series of "8"s where the outcome data should be (see pic).

Second, you can query the MAUDE database using the OpenFDA platform and count the distribution of patient outcomes in the year:
As of this moment, if you click on this link, you will see the distribution of patient outcomes in the MAUDE database from the beginning of 2016 until yesterday. You can see from the pic below that there are no outcomes, only variations on "8."

Update on "8." and MAUDE Patient Outcomes

I have previously posted about the FDA's adverse events database for medical devices (known as MAUDE). In past years, the MAUDE database had captured patient outcome information (whether the patient died, was hospitalized, suffered some form of disability, etc.).

The database no longer reports patient outcomes (it stopped doing so in late 2015). Instead, the database field that should contain outcome data contains the cryptic entry of "8." (the number 8 with a period). I recently contacted the FDA, asking why MAUDE no longer provided patient outcome data. I received the following responses (thus far). I've edited out identifying information (and superfluous text).

This is from an email dated 28 July 2017. It's moderately encouraging. In particular, it's encouraging to know that the patient outcome information  is _still_ captured, and it will probably be added back to the database once they determine what the error is.

I will post updates as they develop.

 Dear Dr. Danese,
Thank you for contacting the Division of Industry and Consumer Education (DICE) at FDA's Center for Devices and Radiological Health (CDRH) e-mail account. As far as I am aware, patient outcome information is still collected on so adverse event reporting forms. So, at this time I am not clear on why this information is not included in the data sets for 2015 and beyond. I am in the process of researching the issue and contacting the medical device reporting staff. I apologize for the delay but hope to have an answer for you next week. ....

I then received a follow-up email on 4 August (Friday)
Dear Dr. Danese, 
Thank you for your patience while I looked into your inquiry. I have spoken with a member of the Information Analysis Branch and it seems some of the patient outcome information may have been inadvertently excluded from the downloadable zip files. xxxxxx has kindly agreed to look into this issue to figure out what happened and how the problem may be corrected. Please feel free to contact xxxx directly. xxxxx name is xxxxxxxxxxxxxx and xxxxx email address is I hope you have a pleasant weekend. Sincerely, 
Division of Industry and Consumer Education Office of Communication and Education Center for Devices and Radiological Health U.S. Food and Drug Administration
And then this email from the Information Analysis Branch (dated 7 August)
