Used to be, when doctors prescribed a drug, they'd open up a book summarizing drugs and dosages,

or go by memory for the common stuff.

But nowadays...

Now you can type in whatever it is, and then it's placing an order via the computer,

so you type in an order of the name of the drug,

and it will pre-populate everything. Juan Carlos Montoy is an emergency medicine physician at San Francisco

General Hospital. He also studies decision-making in health care. He says for an antibiotic,

the default dose programmed into a doctor's computer might be pretty standard, but for pain,

the number of opioids prescribed might vary a lot, depending on the patient and their type of pain.

Well, we wanted to look at is whether and to what extent the presets, the default settings

that we had in the electronic medical record influence provider prescribing.

Specifically, would lower defaults result in fewer opioids being prescribed.

So Montoy's team systematically changed the recommended opioid pill number defaults

in the computer systems of two hospitals in the San Francisco Bay Area during an eight-month period.

Each hospital's pre-existing defaults were

12 and 20 pills, respectively. The researchers dialed in new defaults of 5, 10, 15, or an unspecified
