I quote from the study by Jaan Sidorov: "A considerable body of evidence suggests that widespread adoption of the EHR increases health care costs. Although the focus of this paper is on the limitations of the EHR in ambulatory care, ample research shows that this might likewise apply to inpatient settings."
I am not sure where the body of evidence is for the increase in cost due to adoption of EHR. I would agree that there is a lack of juried studies of EHR benefits, and there are some number of reports of poor implementation. On the opposite side, there are a number of studies which point to the type of benefits that can be attained and some number of
reports from HIMSS Nicholas B. Davies Ambulatory Care Award Winners and other references that demonstrate benefits obtained by ambulatory care practices.
That being said, the practices that receive benefits are those that consciously work to obtain the benefits by changing their operations to take advantage of the new technology. It is not sufficient to simply implement an electronic record; a practice must redesign the way it
operates and train the staff to be able to function in this new environment. It is also important to aim for an interoperable electronic medical record (EMR). As other readers have pointed out, there is a real difference between an EMR restricted to documentation within a practice and an EHR which captures data external to the practice setting, providing the ability to view a longitudinal record of patient care. Using the Davies Ambulatory Care Award Winners as my guide, I list the following measurable benefits cited by those practices:
* Elimination of time required to pull, handle, or file charts
* Reduction of paper forms and supplies
* Reduction in space requirements
* Decreased patient wait time
* Reduced number of telephone calls and reduced call turnaround time
* Elimination of lab charting
* Elimination or reduction of transcription cost
* Reduced time for referral letters.
* Reduced calls and time for prescription refills
* Reduced time to code and more accurate coding
* Reduced claims denials
* Reduced time for insurance reimbursement
Although Sidorov reports that there is little evidence of
reduced labor costs and lower staffing occurring "among the 17 percent of practices possessing an EHR," I question the 17% figure as well as the lack of evidence of labor saving. The benefits in these operational sites resulted in reduced cost per patient visit reported to be from 6% to 29%. Some qualitative improvements cited by this same group included:
* Ability to monitor yearly mammograms in women at risk
* Ability to monitor routine screening (colonoscopy, stress test, etc.)
* Ability to track success in reaching the lower ATP III cholesterol goals
* Ability to track hemoglobin a1C levels
* Ability to track patients who are not at goal for blood pressure
* Ability to find lab and other procedures not resulted
* Increased immunization rates
* Increased staff satisfaction leading to lower staff turnover.
Sidorov worries that if "the EHR leads to increases in such interventions, more lives saved will come at a heavy price." It may be true that interventions may result in more costly medications or procedures, but there is a promise that having analytical data will lead to more appropriate interventions and indirect savings from reduction in more costly emergency or inpatient care.
My anecdotal experience, from visiting well-planned, -implemented siteswhere EMRs have been operational for some time and mature enough so that the electronic record is linked to other settings of care such as hospitals and testing centers, is that there is increased physician
satisfaction based on their ability to have clear, legible records. This could mean that a practice could have higher volumes, but more importantly, it allowed physicians to reduce their time in administrative tasks and thereby facilitate the delivery of quality care and improve customer service.
I would agree the documentation of benefits are still scant, but as electronic records become more pervasive and more integrated with data from other care settings, I think we will look back and wonder how we ever allowed paper records to be "gold standard" of care documentation.
