The truth is that the volume and complexity of the knowledge that we need to master has grown exponentially beyond our capacity as individuals. Worse, the fear is that the knowledge has grown beyond our capacity as a society. When we talk about the uncontrollable explosion in the costs of health care in America, for instance—about the reality that we in medicine are gradually bankrupting the country—we’re not talking about a problem rooted in economics. We’re talking about a problem rooted in scientific complexity.
Half a century ago, medicine was neither costly nor effective. Since then, however, science has combatted our ignorance. It has enumerated and identified, according to the international disease-classification system, more than 13,600 diagnoses—13,600 different ways our bodies can fail. And for each one we’ve discovered beneficial remedies—remedies that can reduce suffering, extend lives, and sometimes stop a disease altogether. But those remedies now include more than six thousand drugs and four thousand medical and surgical procedures. Our job in medicine is to make sure that all of this capability is deployed, town by town, in the right way at the right time, without harm or waste of resources, for every person alive. And we’re struggling. There is no industry in the world with 13,600 different service lines to deliver.
