Frequently Asked Questions and Setup Guide



Q - What is it?

The BOFAS Registry is a secure online database hosted by Amplitude. It is designed for online electronic input of clinical data and set up as a series of questions.
The outcome data covers;

  • EQ5D
  • Complications

Q - How much does it cost?

Use of the database is free, funded by BOFAS, for BOFAS members.


Q - What staff will I need?

A secretary and a nurse / physio / clinician to manage data flow



Q - How do I set it up?


1)    Go to the Getting Started page on the BOFAS Registry page :


2)    Download the two sets of documents;

a)    Documents for clinic; consent, paper form of online questionnaires, setup guide etc

b)    The documents which will be required by your Information Governance (IG) Manager


3)    Contact Amplitude via this link (  Include your First name, Last Name, email address, Institution(s) and GMC number.  Ask to be signed up to the BOFAS Registry.  Your information will then be submitted to the Outcomes committee for approval.  Once approved, Amplitude will issue your username and password.       


4)    Contact your Hospital Information Governance manager, send him/her the documents from 2b, and Amplitudes email address. Await an email from IG granting approval.



5)    Upon receipt of your username and password, you can log on via the BOFAS Portal to your Dashboard and run through the setup, which includes enrolment of your secretary and support staff for data input.



6)    Once you have received IG approval, you may start to enter data onto the BOFAS Registry.


Q - What conditions/procedures do I need to collect data for?

Initially, we are only collecting data for patients who have undergone either of these two procedures:

  • First Metatarsophalangeal Joint Arthrodesis
  • Ankle Arthrodesis

Once the system has become established we look the expand the numbers of procedures that will be included.


Q - How do I use it?

The system is designed in PROMs fashion, ideally for patients to answer the questions electronically, either in clinic onto a departmental tablet / PC, or by email.

In practice, surgeon, nurse or physio collection on paper is commonly required.
(see section on data collection for different methods piloting in vanguard centres)

Data collection points include: 

  • Consent for inclusion
  • Preop
  • 6 months post op
  • 12 months post op


Q -  Is my Trust obliged to provide funding for the staff / activity?

No, but surgeon-level outcome measures are becoming a requirement to practice, a directive coming from high Government.
Pressure on Trusts to provide funding is likely to be leveraged via Care Commissioning Groups.



 Q -   Where will my data be kept?

Amplitude’s outsourced, secure, certified servers (see information in IG Manager’s downloads).

Data safety is assured, and certification and relevant materials to satisfy both users and Information Governance Managers and Caldicott Guardians is contained in the IG repository section.


 Q -  What will my data be used for?

  • For you to Revalidate
  • For you to monitor your outcomes in both absolute and comparative terms
  • To generate NJR-type " funnel plots” for publication.
    This is why BOFAS has chosen to pre-empt requirements and develop a compliant system which keeps control of data and its quality with its surgeons. BOFAS, the BOA and the BOA umbrella committee designed to bring together all the orthopaedic registries (Quality Outcomes Committee; QOC) are working to develop a sensitive, constructive protocol for discussion with surgeons outcome data outside the norm.
  • For audit
  • Not for research, initially. This requires special governance permissions and will be explored later.


 Q -  Who will have access to the data?

At first, just you, BOFAS and Amplitude.

Once you have approved the data, anyone logging onto the BOFAS publishing site, as is the case now with the NJR.
