If Dan Diamond, MD, leaves for work in the morning and forgets his white lab coat -- it's no big deal. But if he forgets his iPhone?

"I either go home and get it ... or I have a family member bring it to me. It's as important as the stethoscope," said Dr. Diamond, a family physician from Silverdale, Wash.

Many physicians like Dr. Diamond are finding that personal digital assistants and smartphones -- mobile phones with advanced features such as built-in PDAs, Internet access and customized applications -- not only keep them connected but also can serve many functions in the practice of medicine.

According to New York firm Manhattan Research, doctors are adopting mobile technology more quickly than is the general public. The group published a report in September 2008 saying 54% of U.S. physicians own a PDA or smartphone. Separate research by Dallas-based Diffusion Group predicts that by 2011, 70% of physicians will own a smartphone or PDA.

That compares with only about 20% of physicians who have adopted electronic medical record systems, though there's hope that increased smartphone use will raise that number. Already, developers are creating EMRs that operate from a cell phone.

"We see a major shift, almost a revolution, coming like a tsunami to all physicians, which will really change the role of mobile phones from gadgets to one of the most prized aids and companions to physicians," said C. Peter Waegemann, CEO and president of Medical Records Institute, a Boston-based Health IT research and consultancy firm.

Part of the cause for the penetration is the fact that cell phones, which initially were designed to simply make and receive calls, have become so technically advanced that it's more difficult to find a cell phone without smart features than one with them. And once physicians have the phones, the applications are easy and inexpensive to adopt -- many are free or cost only 99 cents.

"The reason I jumped on it ... is because I wanted to have more information at the point of care, but I didn't have room for a wheelbarrow in the exam room," Dr. Diamond said.

Manhattan found in its research that drug references are the No. 1 function accessed by physicians who use smartphones and PDAs. But that certainly isn't the only application available. If a resource is available in paper form, chances are it's available for the smartphone.

Medical calculators, normal lab value charts, decision-support tools and EMRs are available for download. Netter's Anatomy Flash Cards are available in electronic form and can be downloaded onto phones for $39.99.

Russ Horowitz, MD, emergency medicine physician at Children's Memorial Hospital in Chicago, has several medical applications downloaded onto his iPhone. He said the handheld system saves him at least an hour each shift. With his iPhone, he can prescribe a medication, look for side effects or interactions, find out if the medication is covered under the patient's insurance and tell the parents how much the prescription will cost, all without leaving the exam room.

Dr. Diamond, who also uses several applications, said staying at the patient's bedside while seeking information makes patient visits more efficient. Because he doesn't have to leave the room to look up formularies or dosages, he can answer almost any patient question on the spot, even if it requires some research.

Erika S. Fishman, director of research for Manhattan Research, wrote in an e-mail to AMNews that one potential downside to the handheld devices is that "some consumers may be uncomfortable and miss the traditional doctor-patient roles of face-to-face interaction without a 'third-party' device."

But some users say that hasn't been the case.

"[Patients] love that I admit I don't know everything, but also that I use technology effectively to find the answers I need," Dr. Diamond said.

Michelle Snyder, spokeswoman for Epocrates, a widely used drug reference application, said an internal survey found 80% of physicians with Epocrates were using it during patient visits, and most say their patients feel more confident because the doctors are looking up information.

Improving technology

Epocrates is one of many companies adapting their products. It started nearly a decade ago with providing online data to download before recently offering its product on smartphones.

Another example is Modality. CEO and founder S. Mark Williams, PhD, an adjunct faculty member in the Dept. of Neurobiology at Duke University, developed a CD-ROM several years ago that dissected the brain, giving the terminology and a brief description of each function. As technology evolved, the CD-ROM application turned into a Web-based application that then turned into a mobile application in 2005. Modality now has nearly a dozen applications for the iPhone and iPod Touch, including Netter's Anatomy, and has about a dozen more in development.

"Students study within very limited windows of time," Williams said. "In my day, you had to lock yourself in the basement for several hours. I'm not sure that happens anymore." Because mobile devices can carry literally an entire medical library, learning can occur anywhere the student is. Williams said his "eureka" moment was the day a student told him he had learned five new brain terms while waiting in line for his latte.

Williams said the applications also are used by practicing physicians for patient education. "That was something we did not anticipate," he said.

Because of the enhanced memory, access to a wireless network and even wireless reception are no longer issues, as the applications are able to live on the phones as opposed to being Web-based applications, which require Internet access. But wireless access is crucial for another advanced feature of the devices: no more syncing.

Many applications provide the latest information or research crucial to patient care, and physicians no longer have to search for updates or sync their PDAs to their stationary computers to receive them. With newer mobile devices, updates are sent automatically to the user when they are released.

An essential tool

Dr. Horowitz believes the use of mobile devices in medicine will continue to grow. Students coming out of medical school have never known life without a cell phone. And there also has been a trickle-down effect, he said.

Dr. Horowitz, 38, in his third year as an attending, said residents seek him out for consults because they can send images or reports to his iPhone. He said it's useful for teaching because he quickly can send links or articles he wants a resident to review.

His iPhone has become such a staple of his daily routine that when he forgot it one day, "I felt powerless."

According to Fishman, more than half of physicians who use a handheld device claim the device is "essential" to their professional practice.

"And since the time and cost of integrating mobile devices into a practice is much less steep than other technologies, such as electronic medical records, mobile use will continue to spread throughout the medical field," Fishman wrote.

According to Waegemann, the growth of mobile clinical applications for physicians is expected to surpass the growth of EMRs. The institute has been working on driving EMR adoption for 25 years. By 2012, use of EMRs and clinical cell phone applications are both expected to be about 30%.

Waegemann and Fishman agree that mobile devices will foster adoption of EMRs and other health IT. "Efficiency gained from mobile-device use can help physicians realize other technology can streamline the day as well," Fishman says.

Waegemann said the development of technology that works in conjunction with mobile devices will help speed up adoption of EMRs. For example, patients can now store continuity of care records on their cell phones and send them to physicians' offices ahead of any visit. In the absence of an EMR, that record would go to a fax machine, which would cause more trouble, he said.

"Access to information is what separates good care from great care," Dr. Diamond said. "And I want to deliver great care."

Building a successful app

Are you technically savvy and do you have a great idea for an application? You could create your own application and possibly make money selling it to others.

Since wireless devices first hit the market in the late 1990s, software developers have created applications to download on their own devices or sell to other users. Device manufacturers are making it easier to get those applications into widespread circulation.

In March 2008, Apple released its iPhone SDK (software development kit) to the public. The kit is free to download. But to make your application available to others on the iTunes store, you must pay $100 and be approved by Apple's iPhone Developer Program. Approved developers can sell their applications at their own price and keep 70% of the profits.

BlackBerry's technology developer RIM announced in October 2008 that starting in March, it will have an Internet storefront for approved third-party developers to sell BlackBerry applications. As with Apple, developers must be approved but can set their own price. Sellers there can keep 80%.

But busy doctors with great ideas who lack either the time or the technical savvy to program an application can find a number of developers to take on the technical aspects.

Richard Crouse, of Crouse Creative, which takes content submitted from authors and dresses it up to make it application-friendly, said applications that take information and segment it into portals that are easy to navigate will attract more users than a simple database full of text. Software developers, which are easy to find with a quick Google search, can take that dressed-up information and turn it into an actual application.

Applications differ from device to device

The number of available applications and how robust they are will depend on the smartphone device you are adopting. Therefore, it's a good idea to see what applications are available before making the purchase.

An online search for the device name and "applications" likely will lead you directly to that manufacturer's application store.

Because Apple opened up its application store to approved third-party vendors last year, the number and types of applications available for the iPhone are more expansive than for most other devices. Applications can be found on Apple's iTunes store and searched by categories, which include finance, news, health and fitness, entertainment and more, or by name if you know what you're seeking.

The BlackBerry Alliance Program runs a site that allows users to search through the products of its alliance members. BlackBerry's technology partner RIM will open its online application store to third-party vendors in March, which should help expand its offerings.

Once you purchase the device, and if it has wireless access, pressing an icon on the phone's screen will take users directly to that device's application store. Applications are then downloaded from the site directly to the phone.
