Root cause analysis is an important tool for finding out what went wrong. If you don't pull up the whole root, the problem will just come back. Process safety managers and engineers use various methods to do root cause analyses.
One of the simplest methods of root cause analysis is known as the "Five Whys." The person conducting the analysis simply starts by asking why things happened at least five times. I am going to use that method to examine the possible root cause(s) of my wife's recent death.
(1) Why did my wife die? Her death certificate states she died from bleeding as a result of the intervention the medical professionals did on her. (I am not going to go into specifics.)
(2) Why were they doing an intervention? Her death certificate states she had an acute circulatory catastrophe, which caused her to pass out at the grocery store.
(3) Why did that catastrophic event occur? Her death certificate states she had a deformity in her circulatory system. I believe this is a presumption because there was no testing or imaging done prior to the event, although I am sure the surgeon could tell what had gone on.
This is as far as the death certificate goes and I did not want them to do an autopsy.
Continuing with the "whys"...
(4) Why was there a deformity or weakness in her circulatory system? Only God knows, but she had chronic inflammation for a long time. That was diagnosed by an immunologist. Had the medical professionals looked into her records, they would have known that.
(5) Why did she have inflammation? This is the key question, in my opinion, and one the medical community never pursued. They harped about cholesterol and blood pressure, although her numbers were not bad. Those are symptoms of inflammation, but they have been labelled as discrete medical conditions: hyperlipidemia and hypertension. Through our own research we learned that the official advice for addressing those issues only leads to worsening of those "conditions," so we found our own paths to improving our health, often by going in exactly the opposite direction. For example, we did the Whole 30 diet for a month. It made big improvements in our health and allowed us to learn what foods were, and were not, causing problems for each of us.
But despite all of our efforts, her inflammation remained and I couldn't figure out why.
Then, two months after she died, I learned she was deficient in vitamin D. I did an entire post on that and I encourage you to read it here. That realization explained everything.
(6) Why was she deficient in vitamin D? Because she never went in the sun.
(8) Why do people parrot that advice? Because they believe those who seem to be in authority.
(9) Why would the authorities give bad advice? That's a very important question, and one people need to pursue on their own. That's because they wouldn't believe it if they were told.
When we understand the "big picture," everything makes sense.
All glory to God.

UPDATE, September 3, 2022...
I know absolutely nothing about the culture of that country, and am pleased things are being done to make people's lives better. That is what God wants. When we see an opportunity to do good, we are called to do it.
As an engineer, I immediately analyze things and try to fix problems. I look forward to debriefing my friend when they are back to see if there are ways I can help. I think some root-cause analysis of the situation would be fascinating to do, and am looking forward to perhaps giving it a try. It's what I do.
This is so much fun!!
