U.S. Deaths by Age Group as of 4/24/2020

People over age 55 account for 92% of COVID-19 Deaths (data from CDC). Sweden is using similar data to leave the country open for most citizens while asking seniors to stay at home. How do we reopen the economy? Self-quarantine seniors; let everyone else get back to work.

us covid deaths by age group 65 plus

Here’s the 2019-2020 Influenza (i.e., Flu) deaths. Again, seniors are 83.5% of deaths. The flu death rate is about 1 per 1,000. COVID-19 death rate is 1-2 per 100, perhaps lower in people under the age of 55 and higher for those over age 55.

Countermeasure: Self-quarantining seniors will help flatten the curve and prevent overwhelming healthcare.

Colorado Deaths by Age Group

Since 90% of deaths are among those over 60, perhaps the best countermeasure is to require those of us over 60 (me for example) to stay home. Most of us are retired anyway. Let others go back to work.

Approximately 51% of Colorado hospitalizations involve people 60-80+, 75% of people over 50. Another reason to ask seniors like myself to stay at home even as the economy reopens. This will help reduce the load on hospitals.

How Long Should Lean Six Sigma Projects Take?

Should a project take 4-16 months or 4-16 hours? Should you measure projects with a calendar or a stopwatch? I think the answer is obvious, but here’s my take on it.

“Hi, I’m Jay Arthur. Every year, we exhibit at lots of conferences with QI Macros so I get to go to presentations by all kinds of folks. Now, last year I saw a presentation by some consultants who said they’d done some research into how long Six Sigma projects take. They found Six Sigma projects take anywhere from four months to 16 months.

“I [thought], “What? How’s that possible?” That makes no sense to me, because I’ve done multimillion-dollar projects in between 4 and 16 hours.

COVID-19 Root Cause Analysis and Countermeasures

I started wondering, what would the COVID-19 pandemic look like as an improvement story. We have charts about cases and deaths. What might be the root causes and potential countermeasures? Here’s my draft Ishikawa-fishbone root cause analysis diagram and countermeasures. Root causes circled in red.

COVID-19 Countermeasures

We screen for guns in luggage and knives on passengers, why not temperatures? 

As of 4/12/20, NYC accounted for over a third of U.S. COVID-19 cases and almost 50% of deaths. It’s a hot zone. According to one employee, Denver General Hospital has not had a single COVID-19 patient. It’s a cold zone. What are the boundaries of the cold zone?

Colorado COVID-19 Cases and Deaths in Control Charts

While most COVID-19 charts show cumulative cases and deaths, I wondered what would happen if we turned the cumulative data into a daily data and plotted it as a control chart. It is possible to use c or XmR charts for this purpose. Process changes chosen based on runs and trends in the data.

Daily new cases still unstable, but hovering around 339/day. Cases began to rise 3/18. Potentially leveling off 3/26. the date of state “stay-at-home” order.

Daily deaths still unstable, but hovering around 12/day. Deaths began rising 3/21, but appear to be stabilizing.  Significant spike on 4/2, root cause unknown.

4/9/20 QI Macros Webinar

More than 40 people signed up for this webinar, with Jay Arthur demonstrating how to use some of the useful features of QI Macros, as well as some of the new features introduced in recent releases of the software.

Some attendees were familiar with the software and already use it, some had only begun to use it; all were interested in learning new ways that QI Macros can help them with their Agile Lean Six Sigma and Quality Improvement efforts. (You can hear him answering questions and comments typed in by webinar attendees.)



If you saw a feature demonstrated in the webinar that might have been added to QI Macros after the version you’re using (for instance, the Templates Wizard, the Fixed Limit indicator or the automated Process Change Wizard), you may need to purchase an upgrade to bring your QI Macros to the current version.

COVID-19 Paramedic Dashboard 2020

One of our QI Macros users offered to share his dashboard of paramedic response during the Seattle area response to COVID-19. His team transported the first COVID patient in America. As you can see, turnaround times (TAT) at the hospital averaged 30 minutes and temperatures spiked in transported patients.

How Crisis Affects U.S. Healthcare Workers

Back in 2002, thousands of miles from New York City, I worked with a hospital in Oregon. I was amazed to find that they had staffing data from 9/11 about the up and down for that month. As you can see in this X Chart, absenteeism (understaffing) was lower for each of the four following days, 9/12-15, and then recovered. I have noticed this pattern with COVID-19 as well: a week of paralysis followed by a return to normal. Unfortunately, healthcare workers haven’t had the luxury of downtime when dealing with the new crisis.

So don’t be surprised if crisis and uncertainty cause you or someone you know to hit the pause button.

The Economy is Sick

If you’ve ever been sick, you know that the only thing you can do is wait it out. Here’s what we’re going to have to do:

“Hi, I’m Jay Arthur, author of “Lean Six Sigma for Hospitals” and the QI Macros [software].

“I know all of you have had some sort of cold or flu or been sick for a while. The day before Thanksgiving in 2014, I had this really heavy cough that came from the darkest recesses of my lungs and I said, “That’s not good.” Then I felt a little worse on Thursday, and on Friday I was diagnosed as having the flu.

“I don’t know about you, but right now, I’m staying home because of the directives around COVID-19. I know there’s a lot of people out there who have been displaced and are out of work, and now might be a good time to learn a new skill. I can tell you: being able to do some data analysis that results in problem solving is a skill that every, every, every business wants.
