ICOR

icor ICOR is a U.S. Food and Drug Administration-sponsored initiative that is quickly evolving into a public-private partnership, with over 30 registries participating worldwide. The purpose of ICOR is to facilitate and enhance inter-registry collaboration through the provision of a supportive infrastructure and the development of a distributed data network that uses innovative approaches to analyze the data.

This approach is well suited to meet our goals of working with all registries, whether they are well-established or in the development stages. We also aim to assist our participating organizations with a creation of a learning network. Most importantly registries maintain control of their own data and, when they collaborate, they can contribute data in a manner that is not resource intensive.

Launched in 2011, the ICOR initiative addresses gaps in evidence and data related to medical implants. The network is composed of more than 70 stakeholders and over 30 orthopedic registries, representing 14 nations. Through a contract with the FDA, ICOR is implementing a worldwide surveillance system and meaningful unique device identification (UDI) system with two important goals: 1) demonstration projects of research and surveillance for hip and knee implants, and 2) harmonization of worldwide implant data through creation of an implant library.

About Us

The ICOR initiative was launched in 2011 with an inaugural conference that was held on May 9-10 at the headquarters of the FDA in Silver Spring, MD. This conference summarized the international data sources and methods for post-market evaluations and surveillance of orthopedic devices. The conference attendants included 73 stakeholders from 29 orthopaedic joint registries (total joint arthroplasty) representing 14 nations. In addition, there were  over 25 non-registry stakeholders representing industry, AHRQ, NIH, CMS, academia, device regulatory agencies, device cataloguing experts insurers and payers.  The meeting was the first main step to build the ICOR methodological infrastructure to evaluate orthopaedic implant safety and effectiveness.

The broad participation of national and international registries at various stages of development ensured a comprehensive approach for ICOR. All stakeholders highlighted the need to develop infrastructure to collaborate and focus on understanding the variability in outcomes of total hip (THA) and total knee (TKA) arthroplasty devices.  Currently, the worldwide registries include information about more than 3,500,000 orthopaedic surgeries capturing all implantable devices on the market.

The ICOR initiative is creating one of the largest worldwide collaboration with registries and academic centers that have research and clinically relevant expertise to establish a network. The ICOR recognizes the need to leverage resources and expertise from multiple stakeholders toward the development and application of innovative methods to address data and methodological gaps in studying orthopedic devices.

There are many needs in the orthopedics that can be addressed as the consortium partnership matures. The partial list includes the following:

-Develop priorities for research that reflect the consensus of different stakeholders
-Address the impact of rapid innovations in devices
-Assist the 510(k) process for approval of orthopedic devices
-Fill the gaps in device identification while unique identifiers are developed
-Address the lack of long term safety data
-Conduct medical device research and close evidence gaps for orthopedic devices

 

Mission and Current Projects

The mission of the International Consortium of Orthopedic Registries (ICOR) Initiative is to facilitate international registry stakeholders’ collaboration and develop innovative methodological approaches for conducting robust analytic studies to fill the evidence gaps.  The additional goal is to improve FDA’s understanding of safety and effectiveness of orthopedic devices.

In order to accomplish this mission, we have begun work on three projects:

1. Development of worldwide implant (prosthesis) database

The purpose of this project is to develop a universal prosthesis database and classification system to standardize prosthesis classification and enhance total joint arthroplasty research collaboration worldwide. The implants of interest are all hip and knee arthroplasty prostheses.

2. Comparison of various bearings used in stemmed hip replacement

The purpose of this project is to understand whether different bearing surfaces in hip arthroplasty surgery have different failure modes and revision rates. This project will target primary total hip arthroplasties and will consider any revision, defined as removal, exchange or addition of any implant part (including exchange of inserts and heads only) as the primary outcome variable.

3. Comparison of various fixed and mobile bearings used in knee replacement

The purpose of this project is to measure whether mobile bearing designs will have a higher rate of aseptic revision than fixed total knee arthroplasties after adjusting for appropriate factors, such as age, gender, and co-morbidities. This project will target primary total knee arthroplasties.

Comparative Studies

ICOR-Figure-1
Figure 1

ICOR has established a distributed data system where standardized data extraction is implemented by the ICOR coordinating center and distributed to participating registries (see Figure 1). Each registry completes the analyses and then de-identified, detailed data summaries including all subgroup effects and interactions are shared with the coordinating center. The data are combined in order to investigate the frequency of revision after surgery, which reflects the patients experience and indicates failure of the implant as well the pain and suffering that necessitates a second surgery.

Over 30 projects have been completed and published.

 

Implant Library

The creation of an implant library and relevant nomenclature for device attributes and characteristics is a critical step in linking the clinical and research communities and facilitating the post-market surveillance of medical devices. In orthopedics, large registries or networks of registries can capture device information on a very detailed level and are particularly important for active surveillance and post-market evaluation. The registries can provide denominator data for adverse events related to specific implants and allow proper conduct of comparative effectiveness studies.

ICOR-Figure-2
Figure 2. UDI database and contribution of ICOR Note: GMDN, Global Medical Device Nomenclature; GDSN, Global Data Synchronization Network; HL7, Health Level 7; SPL, Structured Product Labeling

The FDA Unique Device Identifier (UDI) rule mandates that manufacturers must label medical devices with a UDI code that identifies model and production characteristics. Additionally, manufacturers must provide the FDA with the attributes of UDI-labeled devices to populate the Global Unique Device Identification Database (GUDID), a public hub of standardized UDI data intended to integrate with billing, inventory, and electronic records. The ICOR implant library of clinical attributes and characteristics is an adjunct database to GUDID (see Figure 2).

In order to monitor and evaluate total joint arthroplasty procedures, the specific devices used must be accurately identified and classified. The ICOR Initiative facilitated a standardized process that enabled the development of a universal implant library that all registries could use for consistency of reporting and enhanced inter-registry collaboration. The ICOR process is based on a catalogue number assigned by a company to an implant that will be specific for a particular size or configuration. Any change to the design of an implant necessitates a change in the catalogue number. The combination of manufacturer name and catalogue number leads to unique identification of 99% of products. ICOR is continuing to work with registries to reduce the burden of maintenance and updates for their individual databases based on catalog numbers. As UDI becomes available the registries will also link implant characteristics to UDI.

ICOR-USA (Ortho CRN)

The International Consortium of Orthopedic Registries’ USA Collaboration (ICOR-USA) aims to develop a US national device surveillance network in the orthopedic device space. ICOR-USA is a collaborative effort between the FDA’s MDEpiNet-Weill Cornell Medicine Science and Infrastructure Center, and orthopedic registries such as the American Joint Replacement Registry, Kaiser Permanente’s Total Joint Replacement Registry, the FORCE-TJR project, and HealthEast.

The FDA’s new post-market surveillance vision highlights the importance of national registries and linkages with detailed datasets such as billing or administrative claims data and other routinely collected electronic data for the creation of a national system for post-market surveillance. Total joint replacement is the fastest growing elective device based surgery in the nation, if not in the world, with over 1.2 million hip and knee replacements performed annually in the U.S. With the aging of the baby boomer generation, higher rates of osteoarthritis diagnoses, innovative treatment options, and the growing demand for improved mobility and quality of life, procedure volumes are projected to reach 3 million annually in the next two decades. The performance of thousands of hip and knee devices is the most critical device safety issue in the U.S. today.

Major evidence gaps in device performance exist and, through this project, we will capitalize on a novel partnership within the FDA’s Medical Device Epidemiology Network (MDEpiNet) to build a national infrastructure and fill the gaps in evidence. Our initiative aims to bring together registries in a systematic way and obtain longer, more complete patient follow-up via data linkages. Our network will be a resource to address the safety and effectiveness of new devices as they enter routine usage. Using this data network, researchers will be able to conduct comparative effectiveness studies within a short period after their market entry. Linkages between registries and state/national claims datasets will also significantly benefit registry efforts, including validation of complications, increased follow-up rate, ability for risk adjustment, and increased information about patient characteristics. This in turn will allow the registries to better serve their contributing hospitals by providing more detailed, useful reports.

By harmonizing and linking clinical registry information from diverse registries in the orthopedic setting, we aim to share knowledge about best practices for data collection, linkages with claims and other data systems, analytics, and dissemination. Moreover, the collaboration and demonstration of the value of registries will strengthen support from stakeholders. The consortium can serve as a basis for fulfillment of pre- and post-approval requirements related to orthopedic devices.

Collaborators

Kaiser Permanente

Kaiser Permanente (KP) is a partner within the MDEpiNet Science & Infrastructure Center, and boasts several inter-regional implant registries that capture patient demographics, implant characteristics, surgical techniques, and outcomes, including a variety of orthopaedic devices/surgeries such as total knee/hip, anterior cruciate ligament (ACL), spine, shoulder, and hip fracture. The device registries were developed to address recall situations, disseminate best practices, identify patients at risk for failure and assess clinical effectiveness of total joint replacement implants. In addition to the inter-regional implant registries, KP also has the world’s largest private sector EHRs, KP HealthConnect®. Interconnection of all patient encounters within the EHR allows extraction of laboratory, procedural, diagnostic, pharmacy, and hospital encounters for all members in every patient care setting across KP’s regions. These data supplement inter-regional implant registries and provide a foundation for longitudinal assessment of medical devices.

American Joint Replacement Registry

The American Joint Replacement Registry (AJRR) is the national clinical data registry for total joint replacement that was certified by the Centers for Medicare & Medicaid Services (CMS) as a Qualified Clinical Data Registry in 2014. Founded in 2009 as a supporting organization of the American Academy of Orthopaedic Surgeons (AAOS), AJRR became an independent not-for-profit 501(c)3 organization in January 2015. AJRR is a multi-stakeholder initiative and also owns and manages the California Joint Replacement Registry (CJRR). As of November 2016, AJRR enrolled 826 hospitals from all 50 states and the District of Columbia nearly 600,000 procedures have been submitted to AJRR, with the most recent year of data submissions corresponding to approximately 18% of the annual procedural volume in the U.S. AJRR’s procedural dataset includes information from other large institutional registries, such as the HealthEast Joint Replacement Registry and  the Connecticut Joint Replacement Institute.. It includes as participants 20 of the top 25 orthopaedic hospitals, as ranked by US News and World Report.

Weill Cornell Medicine

The Department of Healthcare Policy and Research at Weill Cornell Medicine (WCM) is home to MDEpiNet’s Science and Infrastructure Center. It was previously a home to Agency for Healthcare Research and Quality (AHRQ)-funded Center for Education and Research on Therapeutics (CERT) focused on medical devices. WCMC and the partners in this effort provide a robust platform for large-scale research and surveillance efforts. Dr. Sedrakyan, the principal investigator, has extensive experience in medical device research and supervision. He worked at AHRQ and FDA, and supervised many large grants and contracts including the CERT program. He is the lead for the MDEpiNet Science and Infrastructure Center and patient-centered comparative research team at WCM.

Medical Device Epidemiology Network (MDEpiNet)

MDEpiNet Public Private Partnership is a voluntary organization within the FDA’s Center for Devices and Radiological Health (CDRH) which is working to build a national medical device evaluation system bybringing together leadership, expertise, and resources to build and operate a national device ecosystem supporting the development, regulation, and use of innovative medical devices. The MDEpiNet initiative was launched under the leadership of Dr. Danica Marinac-Dabic, who serves as the Director of the Division of Epidemiology within the CDRH. Dr. Marinac-Dabic has years of experience in medical device regulatory science, particularly in the area of safety and effectiveness in the post-market setting.

FORCE-TJR

The Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement (FORCE-TJR) registry is created and managed by University of Massachusetts Medical School’s Department of Orthopaedics. To date, FORCE-TJR has collected and analyzed comprehensive post-TJR data on more than 30,000 patients treated by a diverse and nationally representative group of surgeons, and hospitals in 24 states. Urban and rural environments, academic and community hospitals, and low and high volume practices are represented. Patient enrollment is ongoing and will exceed 35,000 in 2015. Uniquely, patients consent to (a) complete annual patient-reported outcomes (pain and function) and (b) report adverse events and surgical revisions at intervals for years into the future. A secure web-based data collection platform is used for direct data submission from patients and clinicians. Longitudinal data is complete with at least 85% follow-up for patient-reported outcomes. Data from patients and clinicians is supplemented with data from a variety of other sources including administrative claims, implant data, and x-rays.

HealthEast

The HealthEast Joint Replacement Registry (HJRR) began in 1991 and was the first community-based registry of its kind in the US. The HJRR has been influential in the development of the national system for orthopedic device study, and has been performing critical research studies and publishing their findings in the field for decades. The HJRR was one of the first participating sites during the development of the AJRR, and remains a charter member of the AJRR organization. They have been participating in ICOR since its inception in 2011.
