Digital records show no effect on diabetes care

The study, of 42 physician practices in two U.S. states, found offices that used electronic records actually gave lower-quality diabetes care than those that stuck with old-fashioned paper records.
On the bright side, diabetes management actually improved across all the practices over the course of the study period. But offices using electronic records lagged.
The findings highlight the fact that switching from paper to e-records, alone, is not enough, according to lead researcher Jesse C. Crosson, an assistant professor at the UMDNJ-Robert Wood Johnson Medical School in Somerset, New Jersey.
"Just having these records doesn't mean they're being used in a meaningful way," Crosson said in an interview.
More needs to be done, he said, to help medical practices translate electronic records into better care.
The study, which appears in the Annals of Family Medicine, adds to others showing that digital records do not magically improve medical care on their own.
Electronic records have been part of a push to improve healthcare quality and cut costs. That's because digital records can, among other things, allow doctors, hospitals and other providers to communicate more easily — with the goal of preventing errors and making sure patients get the tests and treatments they need.
Some electronic systems also have "decision support" software that gives doctors tips on how to best treat individual patients.
The U.S. Congress authorized up to $27 billion in government incentives to get doctors and hospitals to switch to "meaningful use" of health information technology. And by 2015, providers will face penalties if they don't switch.
"Meaningful use" means steps like having up-to-date medication lists for each patient, electronically prescribing drugs, and giving patients electronic copies of their health records if they request.
But so far, studies on the impact of electronic records have been mixed.
There's some evidence that going digital may help cut down on unnecessary tests — but that benefit may be limited to larger doctor-hospital networks using the most-advanced electronic systems.
And it's not clear how much of an effect e-records have had on overall quality of care.
For the new study, Crosson's team focused on diabetes care at 42 medical practices in Pennsylvania and New Jersey, 16 of which had switched to electronic records.
They measured patients' quality of care by looking at how many were getting recommended tests, including regular blood sugar, blood pressure and cholesterol checks — and, if necessary, medication to rein in high numbers.
Over a total of three years, the study found, quality of care generally improved.
At the outset, 44 percent of all patients were meeting treatment guidelines, for example. That had improved to 52 percent at the two-year mark.
But offices using paper records actually did a little better. In those practices, 61 percent of diabetes patients were getting recommended tests two years into the study. That figure was 51 percent among practices using electronic records.
