Health records

Researchers mine tweets in search of health trends

The explosion of social media has given researchers a lot of data to mine and trends to identify, but two computer scientists at Johns Hopkins University say they've developed sophisticated filtering software that is attracting particular attention from public health officials.

Twitter, which launched five years ago, has already been used by computer scientists to try to track the flu.

But when Johns Hopkins University computer scientists Mark Dredze and Michael Paul devised a method to filter and categorize health-related tweets, they weren't sure what they might find. So they decided to sort the tweets (they filtered 1.… Read more

Google euthanizes Google Health, unplugs PowerMeter

Three years after launching Google Health, the company has decided to pull the plug on the ailing personal health records service. The lights are also going out for the Google PowerMeter service, which monitors Web-based home energy use.

The Google Health service will expire on January 1, 2012, but users will have until January 1, 2013, to transfer their data out of the system before it gets deleted entirely.

"Now, with a few years of experience, we've observed that Google Health is not having the broad impact that we hoped it would," Google said in a blog post today. &… Read more

Microsoft sees a role for Kinect in health care

SEATTLE--Microsoft thinks its Kinect motion-sensing game controller will find a spot in operating rooms and doctors offices as it already has in consumers' living rooms.

The software giant, which has been working for years to get health care companies to use its technology, is trying to open doors with Kinect. Today at the Pacific Health Summit here, Microsoft's chief research and strategy officer, Craig Mundie, showed how medical providers can use the technology to improve care.

In one scenario, patients virtually attend group therapy sessions. But rather than displaying their actual images, Kinect allows them to use avatars, which can capture the movements of the arms, shoulders, even eyebrows, while allowing them to maintain anonymity with the group.

"There's a naturalness to it, even though there's a cartoonish quality about it," Mundie said. "But you get a huge amount of clues."

In his scenario, one patient, listening to another member of the group chat, sat with arms crossed, brow furrowed, and appeared disinterested. That could be a clinical sign of depression worth following.

This isn't just about Kinect, though. Microsoft and other big tech companies such as Google have been courting the health care market for years, prompted in no small part by federal initiatives to drive the digitization of medicine. But those initiatives have so far had, at best, mixed success, in an industry that loves the latest technical marvel in equipment but resists the digitization of patient records. But with so much spent on health care, the lure for tech providers is hard to ignore.… Read more

Doctors struggle with transition, but e-records appear superior

As many hospitals and health care centers across the U.S. switch from paper record-keeping to newer, electronic health record systems that qualify them for federal incentives, a team of physician-scientists at Weill Cornell Medical College has been tracking the transition for 19 physicians at an adult ambulatory clinic.

Nearly 4,000 prescriptions for more than 2,000 patients were tracked before the switch, 12 weeks after the switch, and a year after the switch. Researchers found that prescription errors dropped by two-thirds, from 36 percent to 12 percent a year after their physicians had switched to electronic record-keeping systems.… Read more

Skin of Mine helps monitor moles, skin conditions

Directed at the tens of millions of uninsured and underinsured Americans, or for those who want immediate dermatology-related diagnoses, Skin of Mine is a platform for measuring and monitoring moles and other skin conditions.

The app--updated in mid-May and compatible with the iPhone, iPod Touch, and iPad--is now available for $2.99.

The setup is simple: create a free account at SkinofMine.com, upload symptom photos to receive automated analyses, and pay on average $50 to receive a certified diagnosis directly from a Skin of Mine medical professional (these include doctors, nurse practitioners, and physicians' assistants) of the user's … Read more

FDA approves first radiology diagnostics app

There is no shortage of health-related apps. Some 1,500 cater to professional caregivers and laypersons alike for a range of purposes, from counting calories to learning anatomy or pulling up drug dosage recommendations.

But Mobile MIM is the first mobile app to be cleared (just last week) by the U.S. Food and Drug Administration that allows physicians to make medical diagnoses using images transmitted to their iPhones or iPads.

The app transmits several image types, including those from computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine technology such as positron emission tomography (PET). Using software developed by Cleveland-based MIM Software, Mobile MIM allows for not just viewing of medical images, but also displaying measurement lines, annotations, and areas of interest.

While the app is indicated for use only in the absence of a workstation, it's pretty clear that the ability to view radiology images on the go could result in, shall we say, dusty workstations.… Read more

IBM to digitize records for Russian hospitals

IBM announced today that nine hospitals across Russia have switched from paper-based medical systems to electronic medical records using IBM Lotus Notes.

Designed to provide fast electronic medical record (EMR) exchange and unified access to many types of health care data, while at the same time meeting stricter medical information requirements and more secure access to patient information in Russia, the automation system was developed by IBM and Complex Medical Information Systems.

"It provides a single electronic tool for control, accounting and planning which leads to improved operation and higher quality of service," says Roman Novitsky, CEO of … Read more

CES: Tanita unveils wireless body fat monitor for kids

LAS VEGAS--Childhood obesity is a concern throughout most of the U.S., and yet most scales are not child-specific, nor do they take body fat measurements.

So Tanita's BF-2000 IronKids Wireless Body Fat Monitor, for children ages 5 to 17, is an intriguing concept. Just unveiled at CES this week, the monitor is set to be released in March for $150.

Company reps tell me the monitor uses alternating current signals to measure body impedance (a process known as biometric impedance) for body fat calculations. The whole process takes about three seconds for a reading.

Tanita is actually releasing … Read more

Study: EMRs not always linked to better health care

The adoption of electronic medical records, or EMRs, in U.S. hospitals has improved the quality of care in only one of three areas studied, and even in that area, the gains are limited, according to new research by the nonprofit Rand published this week in the American Journal of Managed Care.

Researchers analyzed the quality of care at 2,021 hospitals between 2003 and 2007 across three conditions: pneumonia, heart attack, and heart failure. The number of hospitals using either basic or advanced EMRs grew from 24 percent in 2003 to 38 percent in 2006.

Not only did the … Read more

Audi partnership adds surgeons to team of accident researchers

For an unlucky few, a severe accident will indeed be a learning experience. And the Audi Accident Research Unit puts these lessons to good use.

Audi's team of researchers recreates and deconstructs accident events, taking more than 400 photographs of the vehicle and logging approximately 1,300 technical details in its database to improve safety systems. The carmaker has formed a partnership with the AO Foundation, and Audi's accident database will now be available to the organization's global association of orthopedic surgeons.

The partnership will be a new link in the accident research chain. A case isn'… Read more
