Encourage all States to participate. |
Share best practices and lessons learned and partner with other States to leverage Medicaid program and financing capabilities in implementing Medicaid EHR and HIE efforts. Will address a variety of topics over time, including maximizing American Recovery and Reinvestment Act of 2009 (ARRA) funding, implementing meaningful use requirements in Medicaid, and preparation for incentive payments for health information technology (health IT).
The Collaboration will provide to its members: -
Information collection and dissemination.
- National meetings.
- Liaison between the Collaboration, Federal agencies, Federal policymakers, and relevant partners.2
|
- Educational forums.
- State-to-State mentoring.
- Continuous learning workgroups.
- Workgroup discussions (calls and Web meetings).
- Opportunities to comment on draft guidance from CMS and other Federal agencies.
- Technical assistance opportunities.
- Web site for sharing references, CMS guidance, environmental scan, health IT State plans, HITECH planning APDs by State, consent materials, workgroup archives, and other relevant resources.3
- Conducted survey with participants to assess: most useful technical assistance for HIE, EHR, and e-prescribing; most useful leadership and training opportunities;
and level of staff participation in collaborative workgroups.4

Medicaid Medical Directors Learning Network |
Since 2006, Medicaid medical directors have been meeting to share ideas and best practices related to issues of access,
quality, and costs in Medicaid.
Sponsored by the Agency for Healthcare Research and Quality (AHRQ) and supported by NASMD.
As of 2009, 42 States had joined the Medicaid Medical Directors Learning Network.5 |
Improve the quality and safety of health care delivered to the Medicaid population.6
Focused on specific target problems such as reducing C-section rates, improving preventive screening and vaccinations.
First project: benchmark antipsychotic and mental health drug use in Medicaid children. Data from 16 States were collected to provide best practices to work with providers of mental health to improve prescribing practices.5 This project resulted in a report Antipsychotic medication use in Medicaid children and adolescents.7
Similar approach used to reduce readmissions.5 |
- Offer clinical programs during NASMD meetings in summer and fall.
- Collaborate on targeted research and quality improvement projects.

AHRQ Primary Care Practice-Based Research Networks (PBRNs) |
Primary care practice-based research
networks (PBRNs) emerged between the 1970s and 1990s, all around the United
States, primarily led by family physicians.
Through partnerships with private
foundations, professional societies, academic institutions, and State and Federal
agencies, these PBRN have evolved into much more robust national networks.8
Since the 1990s, AHRQ has supported capacity-building among the PBRNs and currently funds the PBRN Resource Center.8
As of 2009, there were 113 primary care
PBRNs operating throughout the United States.9 |
PBRNs are defined as "a group of
ambulatory practices devoted principally to the primary care of patients.
Typically, PBRNs draw on the experience and insight of practicing clinicians
to identify and frame research questions whose answers can improve the
practice of primary care. By linking these questions with rigorous research
methods, the PBRN can produce research findings that are immediately relevant
to the clinician and, in theory, more easily assimilated into everyday
practice."10
PBRNs are autonomous organizations, often affiliated
with an academic medical center. Some focus primarily on research, while others
incorporate member learning activities as well. (MP) |
Elements of the Network include:
- PBRN Resource Center—provides technical
support, research methodology, education in best practices of primary care
research, and data collection.
- Peer Learning Groups—Conference
calls and presentations on relevant topics such as comparative effectiveness
research, quality improvement research, PBRN operations, health IT, and research
methods.
- Annual PBRN Conference—three-day
meeting sharing information related to primary care and PBRN research.
Opportunity to interact and learn from primary care colleagues.
- PBRN Literature—virtual library
of research conducted through PBRNs.
- PBRN Secure Portal—Secure Web site
for registered PBRNs to share documents, communicate, collaborate, and
develop resources with others involved in the network.10
|
- Membership buy-in is critical. There needs to be value-added to maintain members' interest. The PBRN Resource Center
helps networks conduct membership surveys to assess member interest, experience,
and needs. (CL)
- Even when strong interest exists, finding time is often an issue. (CL)
- Many networks have established practice facilitators or practice coaches as part of the infrastructure. (CL)
- Coordination costs money, and PBRNs may have different cost structures.11
- Less experienced networks gain a lot by collaborating with more experienced networks.11
- Multisite research increases the profile of the networks.11
- A project was conducted to identify best practices in PBRNs. This project was to be completed by August 2011. (CL)
|
Annual assessments are completed during the
AHRQ PBRN registration process. These self-assessed areas include network governance,
network membership, network operations, research issues, and information
technology. (CL)
PBRNs measure their own successes, using
metrics such as level of involvement, number of studies, finances, and number
of publications. (CL) |
Knowledge Translation (KT) Canada |
|
The vision of the network is "To
collectively lead knowledge translation theory and research nationally and internationally
by creating a sustainable organizational structure that supports national and
international collaboration advancing education, theory and research, and
health care delivery service. We see KT Canada as the development of an
intellectual commons to spark innovation, debate, theory building, and
testing of KT research innovations across boundaries: disciplinary,
geographical, institutional, and others."12
The mission of the network is, "To form a
national Canadian research network to identify and study solutions to ensure
that key stakeholders in the Canadian health care system have the opportunities,
tools, and skills necessary to achieve KT in order to improve health for
Canadians."12
The networks goals are to:
- Improve the communication of research results.
- Develop a consensus terminology in knowledge translations and approaches to measuring success.
- Evaluate different approaches to knowledge translation.
- Engage health professionals, members of
the community, and other decisionmaking entities to ensure that the impact of
knowledge translation initiatives is sustained.13
|
KT Canada has four research programs aimed
at the loop between knowledge and action (knowledge distillation; determinants
of knowledge use; selecting, tailoring, and evaluating effectiveness and
efficiency of KT interventions; and sustaining KT). These research projects
are targeted at three key stakeholder groups (consumers, health care
professionals and managers, and policymakers). Each research program and
stakeholder group has a study group that publishes the methodological
insights drawn from the corresponding research program.
Several training programs are offered by KT
Canada for graduate students, postdoctoral fellows, physicians, and the
general public.14 |

Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network |
The Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network was created in 2002, when investigators in pediatric
clinical care who were participating in four multi-site research projects in
the United States and Canada decided to join together and establish one research
network.15
Participation in the network is voluntary.
Participating sites must secure funding for their research projects from
government, foundation, and industry sources.15 |
PALISI is a collaboration of clinical
researchers from 79 pediatric intensive care units throughout North America. Together,
the researchers aim to "identify optimal supportive, preventive, and therapeutic
strategies for acute lung injury, sepsis, multi-organ failure, and other
acute, life-threatening pulmonary or systemic inflammatory syndromes that
affect infants and children."16
The goal of the PALISI Network is "to
perform multi-center research studies to better describe disease processes
and outcomes in pediatric patients and to evaluate interventions in this
population."16 |
- Hold 3-day conferences, twice per year. Opportunity to share research and get feedback from fellow investigators. (SV)
- Also have subgroups that focus on specific topic areas and have smaller group meetings during the biannual conferences. (SV)
- Currently developing a Web site to be able to share research and accommodate the needs of the growing network. (SV)

Robert Wood Johnson Foundation Clinical Scholars |
The Robert Wood Johnson Foundation (RWJF)
Clinical Scholars program supports physician leaders in their efforts to
conduct innovative research and work with communities, organizations,
practitioners, and policymakers.17 |
"The goal of the program is to integrate
Scholars' clinical expertise with training in program development and
research methods to help them find solutions for the challenges posed by the
U.S. health care system, community health, and health services research."17
Through the typical 2-year training
program, scholars receive a master's degree, with significant time allotted
for research.17
Up to 29 scholars are selected each year to
participate at one of four universities across the country.
A critical part of the program is the
mentorship. |
- The RWJF Clinical Scholars program maintains
a strong network of current and past scholars. Several mechanisms are used to
maintain the scholar network.
- Clinical Scholars Online Directory.18
- RWJF Alumni Network creates connections between
alumni of the RWJF's scholars, fellows, and leaders programs to support their
work improving health and health care in the United States.18
- Interactive Alumni Scholars Map.18
- Alumni Ambassadors program to support new
scholar recruitment.18
- Social networking resources include Facebook,
LinkedIn, and a private Wordpress blog, where scholars and alumni can post
information and interact.19
- Web site offers several resources, including
job opportunities, funding resources, and a call for abstracts.

Community Health Care Association of New
York State (CHCANYS) and Primary Care Development Corporation (PCDC) Learning
Collaborative for Meaningful Use (health IT) and the Patient-Centered Medical
Home (The PCMH/MU Collaborative)20 |
Initiated in July 2010. Combines the
expertise of CHCANYS, which has the buy-in of community health centers (CHCs)
across New York State with PCDC, which is a trusted entity within the primary
care community (fits well with CHCs) and has a demonstrated record of success
in building collaboratives. |
Provides CHCs with training and tools to:
- Attain a level of PCMH recognition/designation
that reflects capacities of CHC.
- Enable collection of data that will demonstrate
CHCs have satisfied Stage I Meaningful Use Standards and Measures.
- Identify targets for improvement for CHCs
to progress in PCMH and MU recognition.
|
- Features an "action-learning" approach
that "meets providers where they are" while focusing on teambuilding and
identifying specific, measurable changes (i.e., process) that can be directly
linked to corresponding outcomes.
- Sustainability is "built into" this
effort.20
Specific action elements of the collaborative
(occurring over 6 months):
- Four learning sessions (4 days)
- Three activity periods (8 weeks each)
- Coaching (TBD by situation)
- Phone conferences, Webinars, Webinettes, Sharepoint
Tools (password-protected, shared e-workspace).
|
Not identified. |
Feedback: "Does this meet your needs?"
Detailed PCMH-MU assessments (Note these assessments
are related to PCMH and MU achievements for individual CHCs within the collaborative,
not the work of the collaborative, per se. However, the success of CHCs may
be a measure of success of the collaborative)21 |
Novel Methods Leading to New Medications in
Depression and Schizophrenia (NewMeds).22 Collaboration between pharmaceutical
industry and academic institutions. |
"Research academic-industry collaboration" initiated
in 2009 to explore "new methods for the development of drugs for schizophrenia
and depression."22 |
The collaboration seeks to address
bottlenecks in the drug discovery, development, and clinical trials processes
to bring more medications for schizophrenia and depression to market more rapidly. |
- 10 "Workpackages" introduced at various points
during the drug discovery and development phases (e.g., pre-clinical, Phase I-III)23
- Each workpackage has a deputy (administrative)
and academic (scientific) "lead," both of whom are responsible for the deliverables
of the individual workpackage.23
- Notifies members of upcoming conferences relevant
to their research interests.
- Publications (potentially also a measure
of success).
|
"The one and only supporting action for
every workpackage is communication... Nothing has more power than meeting
someone face-to-face." (KS) |

Centre of Excellence for External Drug Discovery
(CEEDD)24 |
Idea stage: 2000-2005. In 2005, initiated
first "autonomous scientific investment team."24 |
As a "pioneer in the quest to find new
medicines," CEEDD brings together external collaborators to form alliances
for drug discovery, development, and clinical trials at any point in the
process.18 Through this process, CEEDD hopes to "bring more
medicines of value to patients."24 |
- Provides formal guidance to potential collaborators
to "form multi-program, risk-reward sharing alliances" that maintain member
companies' "independence and creativity."24,25
- Seeks out collaborations at any point in
the drug discovery, development, and clinical trials processes.
- CEEDD carefully vets potential partners
for an alliance and only selects those that strongly align with its mission.26
CEEDD approach:24-27
- Semi-autonomous, flexible team (of 25)
- Two centers (U.S. and U.K.)
- Work across multiple therapy areas
- Form alliances at any point in clinical development
- "Full strength of GlaxoSmithKline resources"
"CEEDD of Innovation" and the "Media
Center" are the online voices and platforms through which news about new
alliances and progress in existing alliances is communicated.28,29 |

MindTree, Ltd |
Located in India and the United States (New
Jersey), MindTree was founded in 1999 as an information technology and
business process outsourcing (ITBPO) company. Within 6 years, they earned
$100 million in revenues. The 4,000 employees were called MindTree Minds. Building
a culture of transparency and knowledge management, the basic organizational
unit became a community of practice.30 |
"95% of the people should have 95% of the
information, 95% of the time."30
The company was founded on principles of
creating emotional security, ensuring global communication of information,
and developing capacity to absorb information by making it interesting.
To continually share learning with the world
at large.
The purpose of knowledge management is
helping people to do their jobs better and to develop as professionals. |
To ensure knowledge is created and
disseminated, the organization supported the notion of voluntary communities
of practice.31 The community evolves over time and is motivated by
two questions:
1. What do we want to learn?
2. What do you have to share?
When individuals share an interest and
enjoy talking online, they become a "community of interest." This
is just sharing not learning.
The next level of maturity is "competency-building."
Here people meet face-to-face and learn from each other.
The next level (called capability-building)
was building relationships between other communities, and directly impacting processes.
Finally, the last level called 'capacity-
building' shifts attention from the internal to the external world. |
Communities of practice are informal. If they
can be found on an organizational chart, "they cease to be a community."
All communities have multiple champions who are self-selected and lead the
group.
Communities of practice should have some
face-to-face interactions for brainstorming, telling stories, solving problems,
sharing best practices and service visions, and offering new work tools.
Communities of practice allow for virtual
interactions when people are geographically dispersed.
Shared goals and passionate people create
successful communities of practice.
The key to innovation is collaboration;
before you can become collaborative, you need a social network process. |
At the beginning of every project, they
create a Knowledge Map (K-Map) to identify the knowledge requirements and the
source of knowledge and an action plan. Teams that adopted Kmaps outperformed
projects that did not use them, in terms of on-time, resource utilization,
and, higher gross margins and fewer overruns.
No organizational result is expected, so
there are no metrics.
3% of the workforce were leading a
community of practice, and 75% belonged to at least one community of practice. |
Intermountain Health Care |
In 1975, a group of 15 nonprofit hospitals
came together to form a system called Intermountain Health Care. Today, they
have 150 facilities, 22 hospitals, 25 health centers, and more than 70 clinics.
In 1991, they had a strong consensus that quality improvement and clinical
care management were central to their mission, and they began to roll out
clinical process management throughout their system. In order to do so, they
developed a sophisticated learning collaborative. As a learning collaborative,
they strived to "make it easy, to do it right."32 |
To actively manage clinical care delivery
and to get physicians to learn how to use standardized, evidence-based clinical
practices.
To become a national leader in health
quality and quality improvement. |
- They identified the 60 most common diagnoses
and procedures and the core clinical care programs.
- In these areas, they established learning
collaboratives that conducted literature reviews, defined protocols, and established
key decision points to define current best practices.
- They brought groups of clinicians
together to review the protocols and relied on medical directors and nurses
to oversee implementation.
- They developed tools to manage patients according
to protocols, and monitor performance.
- To integrate clinical services, they
designed an organization with a governance system, a toolbox with electronic protocols,
decision support, and patient health records.
- To manage the learning collaborative,
they allowed physicians to override protocols by managing uncommon cases and
documenting what needs to be improved.
Collaborative projects were based on outcome variance and then RCTs to improve protocols. |
- Knowledge exists not only in the literature,
but it is embedded in the experiences of practitioners.
- To make sure that knowledge is not only disseminated
but also used, a process is needed to support the creation of new knowledge.
New knowledge emerges if outliers are observed when one benchmarks performance
data.
- Knowledge that exists in a community of practice should be codified.
- To create a learning collaborative, learning should come from "real" experience and scientific testing.
|
Intermountain dominates Utah's health
system.
They achieved strong commitment to adopt evidence-based
practice, and much higher than average clinical outcomes.
After developing and implementing
protocols, the learning collaborative, achieved significant reductions in
mortality and readmissions and patients discharged from cardiovascular units
achieved 90% compliance with appropriate medications.
They achieved huge savings in fast-track
extubation, diabetes management, adverse drug event prevention, and
ventilator management. |
Wisconsin Collaborative for Health Care Quality |
In October 2002, nine physician-led health
care organizations and their employer-partners founded a collaboration of
major hospitals and physician groups. WCHC is a "voluntary consortium of
organizations learning and working together to improve the quality and cost-effectiveness
of health care for the people of Wisconsin by developing and publicly reporting
measures of health care performance." Steady growth has been reported since
the collaborative was launched.33 |
The primary goal is to improve the quality
of health care in Wisconsin by publicly reporting performance measures. By making
public outcomes data, increasing transparency of outcomes data, and working together,
that will drive internal managerial and clinical process improvements. |
- Defined a set of performance measures that
incorporates safety, effectiveness, patient-centeredness, timeliness,
efficiency, and equity.34
- The group publishes the data at their Web
site.
- They also convene improvement meetings of
providers and payers and promote frequent communication and informal
interactions to share ideas.
To ensure the quality of the data, they hired an external auditor to check on data reliability and validity. |
- As a learning collaborative, the willingness
to be open and reveal their weaknesses creates value.
- Adopting a set of common performance measures
with common definitions meant providers could not 'pick and choose' the outcomes
to show.
- Learning how to communicate and share ideas
when physical distances do not allow face-to-face interactions requires
relying on telephones and computers.
- A learning collaborative should
ultimately benefit the customer.
|
Baseline performance data and tracking
performance over time have accelerated change and led to a greater sense of
organizational responsibility.
Comparative benchmarking has had a "positive
influence" on health care delivery.
Over time, publicly reporting data created
a sense of urgency to improve. |
