Bundled payments update (2)

 Year 1 of the Bundled Payments for Care Improvement–Advanced Model

A NEJM article shows a negligible effect of bundled payments. Unfortunately, I haven't seen any comment about the flaws in the design. A design mistake for not taking into account a holistic view.

If you reduce 78$ out of 27,315 $ per episode, this is an absolute FAILURE! (it is not a small reduction!!!)

However, the conclusion is:

In this study, we found that the BPCI-A program was associated with small reductions in Medicare payments among participating hospitals. Longer-term evaluation is needed to determine the full effect of the program.

The knowledge economy

 The Knowledge Economy

Adam Smith and Karl Marx recognized that the best way to understand the economy is to study the most advanced practice of production. Today that practice is no longer conventional manufacturing: it is the radically innovative vanguard known as the knowledge economy. In every part of the production system it remains a fringe excluding the vast majority of workers and businesses. This book explores the hidden nature of the knowledge economy and its possible futures.

Incentives for innovation

 Inventing Ideas. Patents, Prizes, and the Knowledge Economy

How do knowledge and ideas influence the competitiveness of firms and nations?

You'll find the answer inside this book:

The twentieth century has been characterized as “the American century,” but at this critical juncture, new global competitors are adopting economic policies and institutions that have the potential to outpace U.S. achievements. Whether the twenty-first century will remain the American century will largely depend on the extent to which the lessons of the past are kept to the forefront. American technological and industrial progress owed to democratic open-access markets in ideas where entrepreneurial innovators succeeded, not by decree of administrators, but because their creations satisfied the ultimate judges—consumers in the marketplace. The evolution of administered innovation systems over the past three centuries largely serves as a cautionary tale rather than as a success story. The economic history of innovations instead suggests that the best incentive for necessary changes is failure in the marketplace; while the best prize for creative contributions to the knowledge economy is success in the marketplace.

AI everywhere (10)

 Atlas of AI. Power, Politics, and the Planetary Costs of Artificial Intelligence

Artificial intelligence is not an objective, universal, or neutral computational technique that makes determinations without human direction. Its systems are embedded in social, political, cultural, and economic worlds, shaped by humans, institutions, and imperatives that determine what they do and how they do it. They are designed to discriminate, to amplify hierarchies, and to encode narrow classifications. When applied in social contexts such as policing, the court system, health care, and education, they can reproduce, optimize, and amplify existing structural inequalities. This is no accident: AI systems are built to see and intervene in the world in ways that primarily benefit the states, institutions, and corporations that they serve. In this sense, AI systems are expressions of power that emerge from wider economic and political forces, created to increase profits and centralize control for those who wield them. But this is not how the story of artificial intelligence is typically told.

The standard accounts of AI often center on a kind of algorithmic exceptionalism—the idea that because AI systems can perform uncanny feats of computation, they must be smarter and more objective than their flawed human creators.

Framing

Framers: Human Advantage in an Age of Technology and Turmoil 

Frames are mental models of the world that we use to understand problems, and to come up with new or refined solutions. As a tool, framing has always been with us. But as long as we were focused on traits like memory and reasoning that were more obviously essential to human cognition, framing didn’t get much attention. Now that computers have become better at some of those cognitive tasks, framing stands out as a critical function—one that matters more than ever because it can’t be handed off to the machines.

Framing means dreaming with constraints, letting your mind wander in a methodical and structured way, or wondering how old tools could be applied to new problems. FRAMERS shows how framing will not just be a way to improve how we make decisions in the era of algorithms, but will be a matter of survival for humanity in the coming age of machine prosperity.

 

A guide to working with frames

I. Harness mental models

  • Framing happens all the time but can deliberately be used to improve decisions.
  • Identify and inspect the assumptions in your mental models.
  • Ask “why” and “how” questions: Why did you reach this conclusion? How must the world work if you anticipate this happening?
  • Imagine how a wise friend, a historical hero, or a rival might frame a certain challenge.
  • Ask yourself what would need to change for you to want to frame a situation differently.
  • When your views clash with another’s, try to characterize the underlying way they see the world.

II. Dream with constraints

  • Applying a frame is about swiftly and efficiently identifying appropriate options.
  • Focus on those elements that are most easily changeable.
  • Start by making minimal changes to your constraints, and gradually contemplate more elaborate modifications.
  • Be careful to remain consistent by weighing whether the change contradicts any underlying assumptions or beliefs.
  • Embed constraints in a physical model if it is too difficult to keep all of them in mind at once.

III. Reframe wisely

  • Switching to an alternative frame lets you see the world differently, but it is risky.
  • See if you already have a frame in your repertoire that will work.
  • Try repurposing a frame that you can apply from a different domain.
  • Invent a new frame as a last resort, since it’s the hardest option.
  • Keep in mind the trade-offs between tight frames (fast but limited) and broad ones (comprehensive but time-consuming).
  • Don’t reframe repeatedly, since it leads to disorientation.

IV. Conditions matter

  • We can improve our framing through cognitive diversity.
  • Develop a curiosity for the unfamiliar to continually challenge your worldview.
  • Be willing to accept tensions among frames: they are less an indication of faulty reasoning than of the complexity of reality.
  • Speak the truth, even when it is not comforting for individuals or organizations. The courage is respected by those who matter.
  • Seek dissent rather than confirmation.
  • When deciding in teams, have each person frame the problem independently before sharing views and deciding as a group.

V. Think beyond yourself

  • The role of society is to ensure frame pluralism to produce optimal responses in times of change.
  • Strive to see the colorful; don’t be color-blind. Speak openly but respectfully about differences.
  • Regard societal friction as an advantage, not a drawback.
  • Use education to instill respect for others’ frames.
  • Promote a commingling of cultures as a way to foster imagination, innovation, and dynamism in a society.
  • Reject anything that presents itself as a single frame to encompass all of reality.
