Reports and Studies

“N.Y. health information exchange aids doctors, patients.”

  • HIE has been shown to: reduce ER admissions to hospital * reduce redundant radiological scans * reduce readmissions  * save time by avoiding use of fax and avoiding need to obtain permission after initial patient consent.
  • 2009& 2010 studies in Rochester NY showed that use of the network made patients 30% less likely to be admitted to the hospital from the ER, 27% less likely to experience repeated radiological scans, & 55% less likely to be readmitted to the hospital within 30 days.  (see study by Vest, Kern, Kaushal et al, below)

NY study links HIE with reduced hospital admissions

Massachusetts Study: Use of Electronic Health Records = Fewer Malpractice Claims (released June 2012)

"We found that the rate of malpractice claims when EHRs were used was about one-sixth the rate when EHRs were not used. This study adds to the literature suggesting that EHRs have the potential to improve patient safety and supports the conclusions of our prior work,which showed a lower risk of paid claims among physicians using EHRs. By examining all closed claims, rather than only those for which a payment was made, our findings suggest that a reduction in errors is likely responsible for at least a component of this association, since the absolute rate of claims was lower post-EHR adoption."

Memphis Study: Emergency Departments and Exchange of Data (released Nov 2011)

"Twelve hospitals in the Memphis, Tenn., area that shared electronic health record data among emergency departments achieved annual cost savings of nearly $2 million and had fewer hospital admissions." [ 11/09/11]

Humana & Wisconsin Health Information Exchange Study (released Aug 2011)

Findings included "an average savings of $29 per emergency department visit due, in large part, to the reduction of test redundancy, which helped mitigate waste and control costs."

New England Journal of Medicine (released Aug 2011)

A study based in the Cleveland (Ohio) area involving more than 27,000 adults with diabetes found that nearly 51% of patients in EHR practices received care that met all of the endorsed standards. Only 7% of patients at paper-based practices received this same level of care– a difference of 44%.
