Driving forces for development of health it

Driving Forces for Development of Health IT

  • Parallels trends seen in other industries

    • Automate administrative functions (billing, financial management)

    • Automate core business processes  access to information, greater consistency

    • Transform core business processes  dramatic gains in quality and efficiency

  • Pre-2000 emphasis in health care systems

    • Administrative—patient management (registration, bed control) and patient billing

    • Systems for clinical departments—laboratory, radiology, pharmacy, operating room, ED

  • Current emphasis, pre-stimulus package

    • It’s not about technology, or even information—it’s about leveraging “I” as well as “T” to transform care

    • Automate risk-prone processes—barcode medication administration

    • Integrate data and systems around the patient, not hospital departments

    • And beyond the bedside—across the continuum of care

      • Integrate across institutions—health information exchange (HIE), regional health information organization (RHIO)

      • Involve the patient and family—personal health record (PHR)

    • Care coordination—Patient-Centered Medical Home (PCMH)

    • Comparative effectiveness research

      • Use real-world data to determine which treatments are most (cost-)effective

  • Economic stimulus package—American Recovery and Reinvestment Act

    • $19 billion for Health IT—combination of grants and loans for purchase, incentives for “meaningful use”

    • $1.1 billion for comparative effectiveness research

    • Promotion of standards and certification, expand privacy protections, “extension” program

Implications for skill development?

...for culture?


Goals for hospital point of care systems

Potential Quantitative Benefits

Recruitmentand Retention

Goals for (Hospital) Point-of-Care Systems

  • Important “twists” in ambulatory care

  • Longitudinal perspective—prevention

  • Fee-for-service payment—documentation

  • Enhance patient safety

  • Reduce unwarranted variation in practice

    • Smart resource utilization  better outcomesat lower cost

  • Improve productivity and convenience for clinicians

    • Physician loyalty  volume

    • Recruitment and retention for nurses and other clinicians

    • Competitive position of GME programs

  • Increase operational efficiency (workflow)

    • Eliminate rework and delay

    • Credibility for resource utilization efforts

Patient safety may be the main reason to adopt point-of-care systems, but safety is only one of many benefits.


Reasons to be cautious

Reasons to be Cautious

  • Technology—EHR is far more than an electronic “record”

    • Point-of-care—decision support, decision execution (workflow management/monitoring), team interaction

    • Semantic interoperability—messaging standards, coding/content (information in “computable” form)

    • Use of data for improvement—analytical tools and skills, leading change

  • Workflow redesign

    • Never “designed” in the first place

    • Hospital ≠ Ambulatory

  • Payment incentives

    • System developers have focused on documentation and coding  tangible ROI (“pay-for-verbosity”)

    • Fee-for-service encourages services: if costs are to be controlled, the payment mechanism must change

  • Culture of collaboration

    • Trust

    • Systems thinking

    • Data-driven QI


Benefits and risks of ehrs

Rate of absorption of stimulus funding

Rate of “Absorption” of Stimulus Funding

  • Informatics training—AMIA 10×10 initiative

    • Both practical skills (project management, workflow redesign) and theoretical work (knowledge representation)

  • Pace of cultural change

    • Organizational structures and governance

    • Clarify roles and expectations, build trust—generational effects

    • Alignment of incentives (payment)

  • Realistic expectations

    • Care coordination in an “open” system—many moving parts to the “medical home”

    • Many complex issues—are “alerts” and provider responses part of the legal medical record?

    • Current products and standards are still maturing—limited adoption, limited measurable impact

  • Stimulus includes $20 billion for health IT and comparative effectiveness

    • Entire US health IT industry was $26 billion in 2007

    • Stimulus funding is a great deal, but it is also not enough to cover full implementation

Benefits and risks of ehrs

  • Alerts and reminders

    • “Evidence-based” care guidelines

  • Documentation standards

  • Potentially even more powerful: customized care protocols

  • Randomized controlled trials (RCTs) are regarded as the “gold standard”

    • Questions are narrow by design, relying on randomization to neutralize potentially confounding effects, in order to obtain “definitive” answers

  • RCTs typically involve younger patient populations, with single diagnoses, over brief study periods

    • Are the conclusions applicable to older patientsand those with multiple diseases?

  • RCTs are expensive and time-consuming

    • Typical drug trial may take 10–15 years and cost $10–300 million

    • Cannot keep pace with development of new diagnostic and therapeutic modalities

“Small-area analysis”


Children s hospital of pittsburgh

Children’s Hospital of Pittsburgh

“The usual ‘chain of events’ that occurred when a patient was admitted through our transport system was altered after CPOE implementation. Before implementation of CPOE, after radio contact with the transport team, the ICU fellow was allowed to order critical medications/drips, which then were prepared by the bedside ICU nurse in anticipation of patient arrival. When needed, the ICU fellow could also make arrangements for the patient to receive an emergent diagnostic imaging study before coming into the ICU. A full set of admission orders could be written and ready before patient arrival. After CPOE implementation, order entry was not allowed until after the patient had physically arrived to the hospital and been fully registered into the system, leading to potential delays in new therapies and diagnostic testing (this policy later was rectified). The physical process of entering stabilization orders often required an average of ten ‘clicks’ on the computer mouse per order, which translated to ~1 to 2 minutes per single order as compared with a few seconds previously needed to place the same order by written form. Because the vast majority of computer terminals were linked to the hospital computer system via wireless signal, communication bandwidth was often exceeded during peak operational periods, which created additional delays between each click on the computer mouse. Sometimes the computer screen seemed ‘frozen.’

“This initial time burden seemed to change the organization of bedside care. Before CPOE implementation, physicians and nurses converged at the patient’s bedside to stabilize the patient. After CPOE implementation, while 1 physician continued to direct medical management, a second physician was often needed solely to enter orders into the computer during the first 15 minutes to 1 hour if a patient arrived in extremis. Downstream from order entry, bedside nurses were no longer allowed to grab critical medications from a satellite medication dispenser located in the ICU because as part of CPOE implementation, all medications, including vasoactive agents and antibiotics, became centrally located within the pharmacy department. The priority to fill a medication order was assigned by the pharmacy department’s algorithm. Furthermore, because pharmacy could not process medication orders until they had been activated, ICU nurses also spent significant amounts of time at a separate computer terminal and away from the bedside. When the pharmacist accessed the patient CPOE to process an order, the physician and the nurse were ‘locked out,’ further delaying additional order entry.” (pp. 1508–1509)

Computer Technology and Clinical WorkRobert L. Wears, MD, MS, and Marc Berg, MA, MD, PhDJAMA, March 9, 2005 — Vol. 293, No. 10, pp. 1261-1263

  • Rather than framing the problem as “not developing the systems right,” these failures demonstrate “not developing the right systems” due to widespread but misleading theories about both technology and clinical work.

  • The misleading theory about technology is that technical problems require technical solutions; i.e., a narrowly technical view of the important issues involved that leads to a focus on optimizing the technology. In contrast, a more useful approach views the clinical workplace as a complex system in which technologies, people, and organizational routines dynamically interact....

  • …There is quite a large mismatch between the implicit theories embedded in these computer systems and the real world of clinical work. Clinical work, especially in hospitals, is fundamentally interpretative, interruptive, multitasking, collaborative, distributed, opportunistic, and reactive. In contrast, CPOE systems and decision support systems are based on a different model of work: one that is objective, rationalized, linear, normative, localized (in the clinician’s mind), solitary, and single-minded. Such models tend to reflect the implicit theories of managers and designers, not of frontline workers.

  • Introduction of computerized tools into health care should not be viewed as a problem in technology but rather a problem in organizational change, in particular, one of guiding organizational change by a process of experimentation and mutual learning rather than one of planning, command, and control….

  • This implies that any IT acquisition or implementation trajectory should, first and foremost, be an organizational change trajectory.

Benefits and risks of ehrs

January 9, 2009

IT-related activities of health professionals observed by the committee in these institutions were rarely well integrated into clinical practice. Health care IT was rarely used to provide clinicians with evidence-based decision support and feedback; to support data-driven process improvement; or to link clinical care and research. Health care IT rarely provided an integrative view of patient data. Care providers spent a great deal of time in electronically documenting what they did for patients, but these providers often said that they were entering the information to comply with regulations or to defend against lawsuits, rather than because they expected someone to use it to improve clinical care. Health care IT implementation time lines were often measured in decades, and most systems were poorly or incompletely integrated into practice.

“Although the use of health care IT is an integral element of health care in the 21st century, the current focus of the health care IT efforts that the committee observed is not sufficient to drive the kind of change in health care that is truly needed. The nation faces a health care IT chasm that is analogous to the quality chasm highlighted by the IOM over the past decade….”

Prospects for the future

Prospects for the Future

  • Growing public expectations—safety and quality are no longer taken for granted

  • Providers face increasing pressures on cost, as well as quality

    • We’ve done all the easy stuff—unit cost, straightforward utilization management

    • We’re forced to address the higher level issues—workflow, process integration, over-use, access to care

    • Growing willingness to learn from real-world experience—data warehouses, analytics

  • We are beginning to see realistic incentives: pay-for-performance programs (P4P)

    • Incent improved care enabled by IT, not HIT adoption per se

    • Still need more fundamental payment reform

      • EHR designs have responded to payment pressures: volume (piecework orientation), “pay-for-verbosity”

      • Align economic benefits with investment

  • Still too optimistic about “interoperable IT” as a solution for a fragmented care system

  • Gaining a critical mass of health care workers who demand, rather than reject, technology

  • Learning to distinguish clinical content and systems thinking from techno-gadgetry

  • Recognizing the possibility of making things worse (negative unintended consequences) and learning how to avoid doing so

We tend to underestimate the long-term impact of technology,but we invariably overestimate the pace of adoption.
