What does the future hold for health and fitness in Canada? Advanced Performance HD (@AdvPerformHD) has been working with @GoodLifeFitness to engineer innovative solutions for complex problems in the #COVID19 era. THREAD. 1/ ImageImage
2/ The #COVID19 pandemic has completely changed how we live, & how we perceive and experience risk. Risk is not binary but rather exists on a spectrum influenced by emotions and experiences, which ultimately drives choices & behaviour Image
3/ The “new normal” has compelled us rethink how we interact: We zoom, we distance, we mask. Society has been required to overhaul designs, processes, and procedures on a massive scale. How do we decide what works and what doesn’t? Image
4/ Moreover: How do we estimate the effect of design interventions? How can we best influence behavioural change? And are there unintended consequences in untested plans?
5/ At @AdvPerformHD we use our #simulation and design expertise to “crash test” new systems and processes to help make data-informed decisions. Our collaborative work helps to answer a key and pressing question: Does work as imagined resemble work as done? Image
6/ In 2020, we worked w/ @GoodLifeFitness to test their re-opening plans (goodlifefitness.com/goodlife-stand…). Engagement, reflection and adaptation are key elements of a learning organization (hbr.org/2008/03/is-you…) that we leveraged towards the creation of new & innovative solutions
7/ To do this, we employed numerous evidence-based practices & behavioural nudges to promote social norms (masks, physical distancing, hand washing) that align with public health recommendations and minimize risk Image
8/ We approached this as a wicked problem (): one that lacks a single unifying solution. We used multi-modal #simulation to generate deep engagement by way of testing, debriefing, feedback, revision & re-design ImageImage
9/ What followed was a complex and novel exploration of how to input behavioural psychology, human factors and design engineering to build a responsible and functional fitness experience Image
10/ Interested in knowing more? Stay tuned for details, specifics and outcomes in Part 2 of our Fitness and Design Series #APHD Image

I've started teaching my daughter effective learning techniques. Here's what the evidence tells us

Best: practice testing, distributed practice

Moderate: self-explanation, interleaved practice, elab interrogation

Worst: summarizing, highlighting, rereading, mnemonics

🧵
1/ Image
I'll briefly mention the techniques that I utilize and teach

1. Distributed practice - spreading out study activities over time
- far more effective to study 1hr for 5 nights than 5hrs on 1 night
- this approach benefits long term retention
- basically cramming doesnt work!

2/
In one study, spaced practice where students had 1 or 30 day between sessions produced better results than 0 days betw sessions when evaluated on the final test

Notably, 30d betw sessions was worst at the beginning but overtime was best strategy

Make no mistake the recent words of the premier touting the strength of our healthcare system are not anchored in reality.

The many amazing healthcare workers battle a dysfunctional system to continue to deliver care despite the govt

Let me help the premier understand better

Working in our current healthcare system is like running on treadmill with no end, no food, no water and the pace continues to increase. It’s not sustainable and eventually bad things happen.
A summary
- there aren’t enough nurses
- rural EDs close regularly (that’s crazy)
- EMRs aren’t compatible across institutions and govt is complicit in this - wasting money, time and harming pts
- there aren’t enough family physicians and those remaining want out

What's the best way to practice to improve skill performance?

We studied this.


TL;DR – No difference betw deliberate practice vs self guided practice

BUT more efficient/faster 6months later for deliberate practice

My thoughts & reflections

A 🧵 https://t.co/qyorTESjqGrdcu.be/deI9l
First, we pulled off one of the largest randomized trials looking at practice in the #meded literature.

We enrolled 176 emergency medicine residents across North America at 5 sites. It was a huge undertaking and not an easy study to complete, esp the retention testing.
Key to this conversation is, what is deliberate practice & mastery learning?

Deliberate practice, long studied by Ericcson requires several elements with a primary goal of improving.

Also referred to as 10,000hr rule (from Gladwell) but this is rather a misrepresentation

Starting March 31st @ONThealth announced they will purposefully & systematically reduce healthcare access to those who are marginalized or under resourced.

Ont govt will end a program that provided healthcare access to the uninsured.

Here’s a 🧵 on what this means.

1/
At first glance, this might seem to only affect visitors or travellers (which it will) however it will deliberately negatively impact many Ontario residents who have lost, can’t renew or have an expired OHIP card.

These are people who are in fact OHIP-eligible.

2/
At our hospital, this will represent 1000s of pts per year.

The vast majority are patients who lack the resources to sort out the process required to apply for or renew an OHIP card.

A process made easier with a drivers licence, home address or collateral forms of ID.

In honour of upcoming St. Patrick’s Day and the luck of the Irish, here’s a post on the importance of luck in decision making.

What is luck? Well, it can be either good or bad and it’s the result of chance. By definition it's out of our control.

Here's a thread: 🧵
1/
Luck is a funny thing when it comes to decisions and our interpretation changes depending on who made the decision.

This week we saw an example of bad luck for clients of SVB. The bank run was completing out of their control.

2/
It wasn’t an unreasonable decision to have money deposited there, at least based on all available information. Its easy to criticize others for putting all their money there without diversifying (not luck but bad decison) which unreasonable...as this isn't an investment!.

Every organization will encounter a crisis.

Here’s how we used the concept of pre-mortem to improve.

This week we @Sim_UnityHealth conducted a multi-disciplinary #simulation of a complete loss of IT infrastructure.

Goal: crash test our processes & ensure ongoing care

🧵

1/ Image
Frequently organizations develop policies for crises but we know that work as imagined is never the same as work as done. @StevenShorrock

Orgs guess how ppl respond.

They hope ppl will remember the procedures.

They 🤞 that the system under stress will work.

2/
But there’s a better way to know with greater certainty how the system and people will respond. And what strengths and deficiencies exist.

We use #simulation to support a pre-mortem.
