NEXT Inventory and Comparison of ICU datasets by Christopher SAUER

"Why talk on differences in ICU databases?"
Ans: becuase data is "CORE"
@ESICM #ml #ai #databases #datascience #LIVES2022

@ESICM Merit of publicly available ICU databases
- no randomzined evidence exists for most clinical situations
-data and pt level insights incredibly useful.
-local epidemiology and treatment difers
-real world data sets help deliver optimal treatment policies.
#DataScience #LIVES2022

@ESICM 1st publicly available dataset MIMIC-3 in 2016,
Beth Israel Deaconess Medical Centre, Boston,MA
>70,000 icu stays, 2008 to 2019
now also includes chest x-rays, emergency room data

What's the logical order of SQL query operations? SQL Query Execution Order (Visualized). #SQL #Databases

1. FROM & JOIN: The DB looks at the tables we specified in FROM and in the JOINs, and then merges this data - this merged data is our starting "working set".

2. WHERE: Perhaps we don't want the whole merged working set - perhaps we want to filter this data, so this means we end up with a subset of our working set - we've retained some rows and discarded other rows.

Without effective testing, there's no way to know if your database has been migrated correctly. There are many things you need to verify.

🧵1/10

#databases #databasemigration #dataengineering #sql #googlecloud

1. Was the database schema migrated correctly?
2. Has all the data been migrated?
3. How about user logins?
4. Can all of the users still connect and can users only access the data they're permitted to access?

🧵2/10

#databases #databasemigration #dataengineering #sql

There are basically three categories of testing that needs to be considered; structural, functional and non-functional.

On this I can agree with @Dominic2306, and go further.

#SW1 #IT and #IG has been in a parlous state for well over a DECADE, and more.

A year and a slew of inquiries after the @HMRC #ChildBenefit #DataBreach in 2007, we #FOIed every Government Department about the #databases...

https://twitter.com/Dominic2306/status/1421826256933359622

..of #PersonalData they held. (Initially just the ones containing over 1 million records.)

I'll have to dig up the responses, but I clearly remember only 4 or 5 (out of 24) even had an #InformationAssetRegister, i.e. just a basic list of all the #databases for which they were...

...'#responsible'.

The responses from @cabinetofficeuk & @10DowningStreet were even more appalling; they admitted allowing officials to routinely make copies of #population-scale data "for policy reasons" with no #oversight, no #audit, no defined #IG processes, and no idea of...

A thread on how I managed to encrypt and store a video using #Flutter

Scroll for links, code snippets, and my general thought process...

Recording and saving videos locally isn't too difficult.

Dependencies:
- camera
- path_provider

#flutter #android #s21 #video #coding

Below is the code for getting a file reference:

Created with @carbon_app

Encryption on the other hand is a foreign language to me. From my research, I learned that each user needs an #AsymmetricKeyPair that can be used to #encrypt and #decrypt data.

To generate these, I used the rsa_encrypt package.

What are the most common types of #NoSQL #databases?

* Document databases store data in documents similar to JSON objects. Each document contains pairs of fields and values. The values can be a variety of types including strings, numbers, booleans, arrays, or objects 1/n

* Key-value databases are a type of database where each item contains keys and values. A value can typically only be retrieved by referencing its key, so learning how to query for a specific key-value pair is typically simple 2/n

* Wide-column stores store data in tables, rows, and dynamic columns, wide-column stores are commonly used for storing IoT data and user profile data. Cassandra and HBase are two of the popular wide-column stores 3/n

Important to keep in mind that #AI is made by humans. Our flaws and biases get encoded and amplified. We need the right diversity of people at the table to design and implement #ArtificialIntelliegence and #ML. #humancentereddesign for all of humanity. #design

https://twitter.com/marcusborba/status/1357116081916309511

Who determines definitions, labels of #data cut offs? Too often we get all nerdy on which variables & factors in the model. But are we even using the right data? #tech #technology types might consider reading Maya Angelou & Toni Morrison and others to think outside the box
#AI

Example: many people are interested in #SDoH #socialdeterminantsofhealth & #data for it.
Who has existing large #databases?
Banks
Banks are traditionally risk averse, block/exclude those who are labeled high risk
So can their data improve health equity?

Exploring variation in the use of feedback from national clinical #audits: a realist investigation @HSRatBMC by @tasha_alvarado
bmchealthservres.biomedcentral.com/articles/10.11…

National Clinical Audits (NCAs) are a well-established quality improvement strategy used in #healthcare settings.@CardiacAudit @HQIP #NHS #MINAP #PICANET @BCIS_uk

Significant resources, including clinicians’ time, are invested in participating in NCAs, yet there is variation in the extent to which the resulting feedback stimulates quality improvement.

@SavvasStephnds

There are a lot of types of databases out there. Which one you use depends on what you need it for. Here are a few examples 👇🧵

#100DaysOfCode #CodeNewbies #databases

▶️ RELATIONAL DATABASE

This is the most popular database out there. It depends on tables which have relationships between them (thus "relational"). Popular examples include:

👉@MySQL
👉 @PostgreSQL
👉 @SQLServer

▶️ NOSQL DATABASE

The opposite of a relational database. It doesn't rely on tables and relationships, which is why it's called No-SQL. It is instead (usually) reliant on documents. Popular examples include:

👉 @MongoDB
👉 @couchbase
👉 @dynamodb by @awscloud

Let’s talk #safetyculture

@TheIHI

It’s a framework for a harm reduction towards all: patients & families as well as all staff

Important:
growth mindset
instead of
fixed mindset

to have needed uncomfortable conversations

#MedTwitter #AcademicTwitter #MedEd #NurseTwitter

This framework has been applied to reducing harm, mostly through medication error (though intended to achieve population health)

Then was expanded to patient experience

Also, cost of care

More recently we have added clinician wellbeing

=quadruple aim

ihi.org/communities/bl…

What has not been clearly stated in any of these #safety framework is disparities, structural inequity, or racism

The acute care side of the hospital - money maker - thinks of this as type of safety & #quality

but not #populationhealth

#Implicitbias elicits 🙄😡😴 response
