emr-ndr.net Topic.6 January 6, 2012: Do EMRs reduce medical costs?


This Part 1 of 2 posts concludes “yes”

The following are interview excerpts from F David Winter, Jr, MD, MSC, FACP

 The excerpts from the interview with DAVID WINTER, MD can be viewed on the documentary website, http://www.emr-ndr.net

IN: Some broadly publicized studies have examined the effect of EMRs on medical costs and quality of care.

F. DAVID WINTER, JR.: A Rand study indicated EMRs would reduce medical costs and improve quality of care; but a Harvard group questioned whether hard evidence existed to support Rand’s findings.

IN: Have you had changes in costs and quality of care since your EMR system was implemented?

 F. DAVID WINTER, JR.: Costs have not decreased. EMR systems are expensive to install and maintain; I do not expect ours to reduce total costs. On the other hand, we used to spend much more on transcription; we have reduced costs there and could end up breaking even.

********************************************************************************

The authors of a Rand paper (Hillestad, Bigelow et al. 2005) state that health information technology can decrease healthcare costs in the USA. In this paper, health information technology (HIT) which is also referred to as electronic medical record (EMR) systems include the EMR, clinical decision support (CDS), IT-enabled functions and a central data repository (CDR) for the information. EMRs contain present and past patient information. CDS presents best practice protocols for patient treatment. An example of an IT-enabled function is computerized physician order entry (CPOE). CDR is the database that contains all this information.  (Hillestad, Bigelow et al. 2005) Most medical records are in paper form. Therefore, the information on the paper cannot be easily used to coordinate patient care, measure quality or track medical errors.

The National Ambulatory Medical Care Surveys, produced by the CDC, did a national probability sample survey of nonfederal office-based physicians.” In 2005, 23.9 percent of the physicians polled had adopted an EHR. The numbers have steadily risen with a 48.3 percent adoption rate at the end of 2009.” (Hsiao, Hing et al.)

The central assumption of this Rand study that EMR systems can influence healthcare cost savings, improve healthcare outcomes and patient safety is based on the assumption that “interconnected and interoperable EMR systems are adopted widely and used effectively."

The impact  of vendor barriers to sharing information was emphasized by the Rand study’s “lower-bound estimate of HIT adoption which assumed an integrated system that had an EMR, clinical decision support, and a central data repository—from the same vendor to ensure interoperability.”

The “estimation of potential HIT efficiency savings” was based on a “literature survey” to identify “evidence of HIT effects”. Expert opinion was sought for their opinion of this evidence. The authors conceded that the “evidence is not robust enough to make strong predictions, and we describe our results only as "potential." Nonetheless, the authors believe that their estimates are most likely an underestimation of the healthcare cost savings due to a number of factors not included in their analysis. Other factors such as “as transaction savings, reductions in malpractice costs, and research and public health savings” can reduce costs as a result of using EMR systems. Interconnected EMR systems may be more effective, than current sources of medical information, in providing data that characterizes the effectives of patient treatments.  Potential changes in the cost and quality of long term care between the current systems of medical information with a fully integrated EMR system is not included in this study’s estimates.

The authors did not include evidence of a “negative or no effect of HIT” because they felt that such a result would be due to “ineffective or not-yet-effective implementation [of EMR systems].Our next blog issue will focus on analyses that do not indicate that EMR systems will result in large healthcare savings. 

The authors assumed a ten- and fifteen-year adoption periods “and excluded products that did not have most of the desirable features of an ambulatory EMR system.

The authors estimated the “potential safety benefits” by using medication error and adverse drug event rates from the literature, as well as limited evidence of CPOE’s reduction of medication error rates”.

Interventions for disease prevention and chronic disease management were used to estimate “other potential health benefits” that would result from the use of “key features of HIT”. The authors used the “literature and clinicians’ opinions regarding the effect of the interventions” to calculate the “potential safety benefits” that would be realized by the use of EMR systems.

The authors analyzed evidence from other industries (telecommunications, securities trading, and retail and general merchandising) that adopted IT for its impact on productivity.  The impact of IT on these industries over more than years can be seen with the introduction of “bar-coded retail checkouts, automated teller machines, consumer reservation systems, and online shopping and brokerages.” Experts estimated that about 25-35% of the 6-8 percent of the annual productivity growth was related to its “IT investments”. On the other hand, the hotel industry did not experience a significant increase in productivity presumably because it “underused its IT investment”. The authors estimated productivity gains in healthcare over an 8 year period to be from 1.5% to 4% annually. This represents the productivity gains in retail/wholesale and half of that realized in telecommunications. This represents an “average annual [healthcare] spending decrease of $346 billion, and the upper end, $813 billion. “

The authors identified   6 “ingredients” that were needed to achieve a productivity growth that was realized by “the telecom and securities industries: gains of 8 percent or more per year, year after year”. The ingredients were “strong competition on quality and cost, substantial investments in EMR systems, an enhanced infrastructure that can accommodate increased future demand or reduce costs without increasing labor, a strong champion firm or institution that drives change and integrated systems”.  Most of these factors are “absent” in our healthcare industry.

The Potential Efficiency Savings from HIT were based on the assessment of decreased costs from both outpatient and inpatient activities based on “a simulation model of HIT adoption and scaling literature-based HIT effects”. The outpatient activities included transcription, chart pulls, lab tests, drug usage, and radiology. The inpatient ones were nursing time, lab tests, drug usage, length of stay and medical records. The largest sources of the estimated savings were from “reducing hospital lengths-of-stay, nurses’ administrative time, drug usage in hospitals, and drug and radiology usage in the outpatient setting.”

The authors estimated that at 90% adoption rate of EMR systems would results in average annual savings of $77 billion. This estimate is smaller than the “annual IT-enabled productivity gains just described in other industries”.  “Process changes” and “resource reduction” are needed to realize this savings rather than “radical changes in the health care delivery system”. These efficiencies and costs savings could be used to improve health care quality. Healthcare providers, according to the authors, have less incentive to purchase EMRs because there is usually a net revenue loss from this expense.

In February 2009, Congress passed a stimulus bill allocating $150-billion to healthcare. A large portion of this, thirty-six and a half billion dollars, is for health information technology. Most of these billions will be spent on electronic medical records (EMRs).

CPOE is at the heart of the potential safety benefits of EMR systems with its use of reminders, alerts and other components contained in this system. “CPOE makes information available to physicians at the time they enter an order”. This is called “decision support”. Drug-drug interactions are such an example. These systems can track each step involved in a drug order and, therefore, enable it to update the process when errors are discovered. In the in-patient setting, alone, the authors estimate a $1 billion per year savings by reducing adverse drug events. Length of hospital stay, in this estimate, is significantly impacted by decreasing adverse drug effects in those older than 65 years of age. The amount of hospital bed days caused by adverse drug effects is so large that estimated savings accrues even though this age group comprises only 13% of the population. There is less data on the frequency of adverse drug events in the out-patient setting and, hence, on the estimated savings that might accrue due to a reduction in such events. But, small practices such as the solo practioners could comprise about 37% of the potential savings in this out-patient setting. (Wang 2003)

The potential health benefits of EMR systems are based on two interventions: disease prevention measures and chronic disease management.  The following components of EMR systems will be used to realize improved safety benefits: “communication, coordination, measurement, and decision support.” These components will allow a reduction in the 50% failure rate of physicians to deliver the recommended care to their patients. The cost of caring for patients with chronic disease consumes 75% of the national health care dollars. (McGlynn, Asch et al. 2003)    Similar failure rates found in adults to delivery care were found in children. ."(Mangione-Smith, DeCristofaro et al. 2007)

Reactions to the McGlynn study have ranged from agreeing with its predictions and suggesting that future studies should look for improvement of these numbers (Steinberg 2003) to skepticism that the authors recommendations can be carried out in a significant manner because physicians workloads presently leave little room for a significant increase in hours worked that would be required to implement the changes they recommend. (Spiegel and Pechlaner 2003)

Another aspect in the ability of EMR systems to achieve health care benefits is through the use of health information exchange regional health information network (RHIN) or personal health records can facilitate the more accurate flow of patients’ medical information with multiple chronic illnesses between different physicians’ and hospitals. This issue will be discussed in a future blog.

EMR systems use “patient data (such as age, sex, and family history)” to identify patients needing “preventive services (such as screening exams)”. Reminders have been shown to increase patient compliance “with preventive care recommendations” when they are used during routine patient follow up visits. (Burack 1997 )

Although increased compliance results will increase health care use and cost “modestly.” The authors estimate that cervical cancer screening can increase life years gained as a result of this screening by 13,000 at a cost of $0.1-0.4 billion.

Using HIT for near-term chronic disease management

Over a 3 year period through 2000, 15 chronic diseases accounted for 50% of the increase in healthcare expenditures, 5 of which accounted or 31% of that increase. (Thorpe, Florence et al. 2005)

EMR systems can use predictive modeling algorithms to target high risk populations for specific types of interventions that can prolong survival, decrease complications and costly acute interventions.

The authors of the Rand study stated that using national disease registries allows for physicians to compare their performance to others. Electronic messaging can facilitate communications between patients, specialists and remote home monitoring of a patient’s data. This allows health care provides to quickly respond to a developing medical problem. Web based patient education can “increase the patient’s knowledge of a disease and compliance with protocols.”

Improved control of acute care episodes of four common chronic diseases, asthma, congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and diabetes with EMR system management resulted in a decrease of admissions to hospitals decreases and increased outpatient office visits and use of prescription drugs for a net decrease in the cost of managing these diseases by as much as $10 of billions of dollars per year.

The authors identified a “key misalignment of incentives”, the savings resulted from a decrease in acute care provider income, which is an “important barrier to EMR adoption.

“Since chronic diseases are, by and large, diseases of the elderly, a large fraction of the long-term savings attributable to prevention and disease management would accrue to Medicare. Yet, to realize these benefits, people would have to begin participating in these programs as relatively young adults.”

“We estimated the potential combined savings, again assuming 100 percent participation, to be $147 billion per year.”

For these benefits to be realized a “a substantial portion of providers and consumers participate.” The authors assume that about half of the patients will be compliant with the EMR systems because that is the percentage that complies with their medical therapy. (Haynes, McDonald et al. 2002)  Only about 10% of patients comply with physicians’ lifestyle recommendation. (Roter, Hall et al. 1998) The authors assume that with “EMR-based reminders and decision support and patient-physician messaging, we could realize at least 20 percent of the long-term benefits.” This represents a net savings on the order of $540 billion per year.

The estimated of the costs of implementation of EMR systems in physician offices in the United States has been in the range of “$28 billion per year during a ten-year deployment, $16 billion per year thereafter and net savings ($21.6–$77.8 billion per year, depending on the level of standardization) of a broadly adopted, interoperable EMR system.”  For hospitals, the “cumulative cost for 90 percent of hospitals to adopt an EMR system is $98 billion if 20 percent of hospitals now have such a system.”

The net cumulative and yearly potential savings

For hospitals and physician practices, the benefits over costs from EMR systems could be nearly $371 and $142 billion over fifteen years. This benefit doubles if the “savings produced by chronic disease prevention and management were included. “

Although the authors predict that “potential savings would outweigh the costs relatively quickly during the adoption cycle” of EMR systems, there are barriers that might impede the “adoption and effective application of EMR systems”. These are the “acquisition and implementation costs, slow and uncertain financial payoffs, and disruptive effects on practices… providers must absorb the costs of EMR systems, but consumers and payers are the most likely to reap the savings and the market might fail to develop interoperability and robust information exchange networks. “ (Bates, Ebell et al. 2003; Miller and Sim 2004) Because of this the authors conclude that there is a “substantial rationale for government policy to facilitate widespread diffusion of interoperable HIT.”

Updates from literature since this publication:

A review of just a few of the more recent publications that support the RAND HIT Project’s predictions are summarized.

The Health Information Technology for Economic and Clinical Health Act (Blumenthal 2009)has provided incentives for the adoption and implementation of EMR systems.

Miler describes a 10 percent increase in births that occur in hospitals with EMRs reduces neonatal mortality by 16 deaths per 100,000 live births as a result of EMR “assisted careful monitoring” .  The authors calculated “cost-effectiveness” valued at $531,000 per baby's life saved. (Miller and Tucker 2011)

The use of the EMR was associated with a significant reduction in hospital mortality in trauma patients.  (Deckelbaum, Feinstein et al. 2009)

The adoption of EMR systems allowed an increase in chart reviews which resulted in an increase in antimicrobial recommendations. This was associated with a sustained decrease in antimicrobial use and nosocomial infections with methicillin-resistant Staphylococcus aureus following implementation of the EMR. (Cook, Rizzo et al. 2011)

Summary

In summary, the authors of the Rand paper outline the basis for their projections of large cost savings with the implementation and widespread use of EMR systems in the USA. Two of the ingredients, discussed in this Rand paper, strong competition on quality and cost and integrated systems, will have a limited impact on the EMR systems’ ability to deliver such savings until the present barriers of patient privacy regulations and the proprietary nature of medical information can be adjusted to accommodate the sharing of medical information between hospitals and physicians.  (Blogs 1, 2, 3).

The assessment of the quality of patient outcomes in an more accurate manner then is done today would require that medical databases use the master patient index (MPI) that allows the tracking of individual patient treatments and outcomes as compared to the standard of “de-identified data” used in medical databases across the country except for a few states like Utah that uses the MPI. Nonetheless, that the state of Utah was able to introduce the MPI to replace the use of de-identified data in its state medical database indicates that patient privacy and proprietary medical information can co-exist with this method of tracking individual patient outcomes.

Another issue raised by this Rand paper is that Americans will have to start making value judgments about the cost of extending patients’ lives which medical innovations allow. The EMR systems will be an integral component of this process as discussed in this paper. For example, an increase in patient compliance with cervical cancer screening can increase life years gained as a result of this screening by 13,000 at a cost of $0.1-0.4 billion. This comes out to a healthcare expenditure of $7,692 to $30,769 per patient for each year of life extended for the high and low end estimated cost of the screening. 

Clearly, each country has to decide the value that the public and private healthcare sectors will pay for each year of life that is extended by such screenings. Today, such decisions are made on a case by case basis in committees that, often, are not transparent to the public, by private insurance companies and the federal government. As the economist, John McCracken, said in the documentary, “EMR and Healthcare Reform” which can be found at www.emr-ndr.net, there is no right or wrong answer to this issue. It is a matter of values.



Part 2 of this topic will be in the next blog which will present the case that the large cost of implementing EMR systems in all hospitals and physician offices in the USA, estimated by some experts to be more than $100 billion over a ten year period, will not realize the large healthcare dollar savings that experts on the Rand panel have predicted.  Some experts have said that the cost to implement the federal mandate to install EMR systems nationwide by 2014 could be one of the most expensive failed federal government initiatives because these EMR systems cannot produce the cost savings that experts have predicted relative to the cost of implementing these systems.

Metamorphoses Healthcare is a non-profit organization that advocates for the establishment of a national disease registry as an adjunct to the federally mandated purchase and installations of EMRs in all hospitals and physician practices by 2014.

The views presented in this organization’s documentary, “Electronic Medical Records and Health Reform”, focus on physicians' opinions about these issues. These physicians represent a diverse group. They are from a different background in regards to race, ethnic ancestry, religion, regions of the country, medical specialties, and political views (from conservative to liberal viewpoints).

The goal of this organization is to identify reforms that benefit the quality of patient care outcomes. We do not advocate a particular political point of view. That is we are a non-partisan organization.
