ODIN is a collaborative group of centres with an interest in periprosthetic joint infections. It encompasses surgeons, infectious disease physicians, nurses, researchers and pharmacists.

ODIN began through a round-table discussion surrounding PJIs. The current literature regarding PJIs is heterogeneous. PJIs can also be considered rare but devastating events. The combination of these factors lead to the recognition of the need for international collaboration to allow meaningful conclusions through the analysis of large cohorts. This lead to reaching out to centres with an interest in PJIs and an agreement to combine resources to tackle PJI research resulting in ODIN.

The primary aim of ODIN is to improve periprosthetic joint infection prevention, diagnosis and management through evidence based research using "big-data": a large registry of homogenous PJI data.

Any centre with an active interest in managing periprosthetic joint infections affecting knee and hip arthroplasty are welcome to apply to join ODIN.

The cornerstone of the ODIN collaboration is the PJI Registry. The Registry relies on collaborator participation via contribution of accurate and comprehensive de-identified patient data using a RedCAP.

Joining is via an Expression of Interest (EOI) either through this website or via one of our current members. The EOI would then be discussed within the governance unit of ODIN and acceptance confirmed. As a basic guide, a centre that would like to join will need to: 1) Obtain ethics to collect data from their centre. 2) Set up a local database in RedCAP (we can help with this) using a pre-specified data-dictionary. 3) Retrospectively collect approximately 5-10 years of data. 4) Once a certain level of data has been collected (this level is variable depending on the size of the centre applying), then the centre would be eligible to join ODIN. 5) Joining ODIN would involve an amendment to the ODIN ethics application, which would then allow data-sharing between centres.

Yes. There is a small fee to join ODIN as the addition of a new centre involves an ethics amendment on our end, and that carries a small fee which will be passed on.

The ODIN Registry is a comprehensive registry of prosthetic joint infections with approximately 900 data points per patient. It is both retrospective and prospective in nature. It encompasses demographic data, index procedure surgical data, peri-operative clinical data, diagnostic data, management and outcome data, microbial and anti-microbial data and patient reported outcome data. It is run through a RedCAP database and is de-identified in nature.

Data is collected via RedCAP from individual centres. Each individual centre is required to have their own RedCAP registry, or be able to utilize an existing ODIN registry. All registries use the same data-collection form, allowing easy collaboration of data amongst participants.

Once you have joined ODIN, we will describe how to propose a question and draw data from the global data-set.

Yes. All shared data is de-idenfied in nature.

All data remains the property and its accuracy is the responsibility of the institution which collects and uploads the data.

Yes, within limitations of current ongoing research projects and ethical board requirements.

The ODIN Registry collects data about joint replacement infections. Data includes information on the operation undertaken, how the infection was diagnosed and managed, what bugs were responsible for the infection and what the outcomes were.

All data within the registry is held securely and remains de-identified. No identifiable data will be held or be accessed by other members of the group.

If you would prefer your data was not used within the registry, please contact your treating centre.

Unfortunately because all data on the Registry is de-identified, it is impossible to view a particular individual's data. Any request for obtaining personal data should be directed to your treating centre.

The data is used to improve prevention, diagnosis and treatment of joint repalcement infections.
