The Three Laws of Robotics  are a set of rules devised by the science fiction author Isaac Asimov. The rules were introduced in his 1942 short story “Runaround“, although they had been foreshadowed in a few earlier stories. The Three Laws, quoted as being from the “Handbook of Robotics, 56th Edition, 2058 A.D.”, are:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

How many people do you know who’ve bought a Fitbit or similar device to track their exercise patterns–who have then let the whole venture lapse? The Fitbit now resides comfortably and peacefully in their drawer!

Well, there’s a useful way to recycle them, offered by Tufts University professor Lisa Gulatieri. As noted in this article:

Gualtieri started RecycleHealth in April with the goal of giving unused activity trackers — mostly Fitbits so far, but RecycleHealth accepts all devices — a second life. The company has collected about 20 devices so far and has plans to donate them to the Montachusett YMCA in Fitchburg, Massachusetts, where they will be used to help older and lower income individuals have access to devices, as well as to learn about how those populations interact with activity trackers.

Check out the Facebook page for stories on how the idea is spreading, plus more information, including how to get free mailing labels.

The Aga Khan delivered the Samuel L. and Elizabeth Jodidi Lecture at Harvard University yesterday.  He has been a strong proponent of pluralism in the world and has devoted billions of dollars in resources from the Aka Khan Development Network to enhancing education, health care , culture, and economic development in the world’s poorest countries in Asia, Africa, and the Middle East. The full text is here, but I offer a pertinent excerpt, with lessons about an increasingly divisive level of political debate in the US and elsewhere:

In looking back to my Harvard days (in the 1950s), I recall how a powerful sense of technological promise was in the air — a faith that human invention would continue its ever-accelerating conquest of time and space. I recall too, how this confidence was accompanied by what was described as a “revolution of rising expectations” and the fall of colonial empires. And of course, this trend seemed to culminate some years later with the end of the Cold War and the “new world order” that it promised.

The joke goes like this:

Sherlock Holmes and Dr. Watson decide to go on a camping trip. After dinner and a bottle of wine, they lay down for the night, and go to sleep.

Some hours later, Holmes awoke and nudged his faithful friend.
“Watson, look up at the sky and tell me what you see.”

Watson replied, “I see millions of stars.”

“What does that tell you?”

Watson pondered for a minute.

“Astronomically, it tells me that there are millions of galaxies and potentially billions of planets.”

“Astrologically, I observe that Saturn is in Leo.”

“Horologically, I deduce that the time is approximately a quarter past three.”

“Theologically, I can see that God is all powerful and that we are small and insignificant.”

“Meteorologically, I suspect that we will have a beautiful day tomorrow.”

“What does it tell you, Holmes?”

Holmes was silent for a minute, then spoke: “Watson, you idiot. Someone has stolen our tent!”

There have been some interesting and important discussions flying across the web in recent days on the issue of protocols in helping to reduce variation and reduce the incidence of harm to patients.  My mistake in the debate was assuming that medical leaders would be reasonable about how protocols should and should not be used.

A doctor friend, highly committed to patient safety, notes:

My point about the protocols is that I have been chastised for not following them in situations where it was blatantly obvious that they did not apply. (“The protocol is there for a reason.”)

The chastisement comes not from hospital administrators, but from clinician leaders in the doctor’s own department:

We just got another email scolding us for not following the “colorectal pathway” sufficiently. One of the provisions of that pathway, for example, is strict limitation of iv fluids, sometimes difficult to “comply” when patients are severely dehydrated from their bowel preps, particularly the elderly.

The initial goals were to decrease opiate use and decrease PACU LOS, both worthy goals, but we’re all annoyed at being beaten over the head with them and getting our hands slapped if we deviate, even with good reason.

It’s ironic that on the one hand we are extolling the virtues of gene-based individualized therapies, but on the other hand we are trying to pigeon-hole every patient into a standardized protocol.
