Swiss Implant Register - SIRIS

New SIRIS forms from 01 January 2021!

Please use the new forms for all interventions from 01 January 2021!

General information on the revision of the survey forms

The revised survey forms of the Implant Registry Hip and Knee are in use as of January.
In order to further increase data quality and prevent input errors, the online data entry has been revised and supplemented with additional filter questions and validation rules.
In terms of content, the questionnaires were revised in collaboration with the expert groups of Swiss Orthopaedics and the SIRIS Scientific Advisory Board and supplemented where necessary, and the "Help menus" were newly created. The previous "drop-down fields" were replaced by so-called radio buttons and all paper forms were completely redesigned. We recommend, whenever possible, to make the entry in the online portal.

Here you'll find the updated user manual (german).

Welcome to the Swiss Implant Registry SIRIS

This medical registry makes a valuable contribution to the detailed assessment of the long-term implant or treatment quality and serves as an early warning system for product and process errors.
Every year around 22,000 artificial hip joints and 18,000 artificial knee joints are implanted throughout Switzerland.
About 800 doctors in 157 clinics carry out the interventions. About 95% of these hip and knee implants are already recorded in SIRIS.

The holder of this register is the Foundation for Quality Assurance in Implantation Medicine. This independent and non-profit organization was founded in 2007 by Swiss Orthopedics, Swiss Medtech and santésuisse.
