The figures come from Surescripts, an association of pharmacies and drug-benefit mangers that now permits doctors to order prescriptions electronically, instead of scribbling out a paper order. The data show two things. First, how recently e-prescribing began. Only in 2008 did the numbers become significant enough to track. Second, how rapid the uptake has been. This year, more than one in three drug prescriptions are expected to be written electronically.

Worth noting is that Surescripts—a company few people have heard of—has now become the largest exchanger of medical information in the U.S. That is because its system also queries pharmacies to learn all the medications a patient has purchased in the past. That means it provides doctors with a medication history, letting them know what medicine you take, potentially avoiding dangerous drug reactions. 

In the future, the idea is that doctors will be able exchange not only medication histories, but your entire health-care dossier. Of course, as medical records go online, security is a looming concern. Since 2009, hospitals and doctors have been reporting to the Department of Health and Human Services all thefts or loss of protected patient data (such as Social Security numbers or medication histories) affecting more than 500 people. Consider the following summary of breaches reported in 2010.

Lost and stolen laptops were a major culprit, followed by lost hard drives and hacker invasions of hospital servers. According to these data, paper seems like a comparatively safe way to store medical records. What's certain is that if the pace of data loss continues, just about every American can expect to have their health information privacy breached in their lifetime.

According to surveys, hospital executives don't think they can protect your electronic data, either.

Just as with using programs like Facebook, people may simply need to get used to the idea that they are giving up some privacy in order to gain the benefits of having their data connected to a wider network of innovation in health-care software.

Data show that doctors are aggressive consumers of new technology, particularly tablet computers.

American adults who own an iPad: < 8 percent

U.S. doctors who own an iPad: 30 percent

Doctors who plan to buy one in next six months: 28 percent

By contrast, consumers aren't adopting mobile medicine quite so rapidly. While many people use the Internet to research health information (59 percent of adults, according to Pew Internet), far fewer are prepared to accept electronic media as a substitute for a check up with a real doctor. Technology Review found the following data points worth noting.

Percentage of people who don't want to chat or IM with their doctor: 78 percent

Percentage of people not interested in talking with their doctor over Facebook or Twitter: 84 percent

The odds that a woman wants to chat online with a doctor, compared to a man: +100 percent

Percentage of adults who think online health records will negatively affect their privacy: 49 percent
