[RSO in clinical practice: Status in Germany 2020].

BACKGROUND

Radiosynoviorthesis (RSO) is a local radionuclide therapy of inflammatory joint diseases, successfully performed since several decades mainly as an outpatient-protocol in ambulatory health care centers or nuclear medicine practices. Despite of long-term experience in some centers, only very few valuable or comparable data about the procedure itself and/or the clinical results of this treatment are available.

OBJECTIVES

The aim of this online survey is to assess reliable data of the current status in Germany.

MATERIALS AND METHODS

A web-based questionnaire was designed to evaluate the status of RSO in Germany including demographic data, training, pretherapeutic diagnostics, clinical procedures, and follow-up. The survey was distributed via the supplier of RSO-nuclides, national nuclear medicine societies, and personal networks. It was available for 28 days and closed on November 30, 2020.

RESULTS

A total of 78 specialists in nuclear medicine answered the questionnaire, which corresponds to a response rate of 23 %. Several differences and concordances in pre-therapeutic diagnostics, in the procedure of RSO itself, and follow-up were documented in this survey for the first time. Most important, less than 70 nuclear medicine specialists in Germany perform more than 75 % of all RSO-procedures and most of them are older than 50 years of age. This implies the urgent need of a dedicated advancement of young academics in nuclear medicine and a professional advanced training in RSO to offer this beneficial treatment to future patients.

CONCLUSIONS

To achieve these goals, an association of RSO experts would be useful, through which, among other things, an RSO training curriculum is developed and theoretical and practical trainings are organized. Moreover, possible cooperation agreements between ambulant and inpatient institutions would foster the education of young nuclear medicine specialists interested in RSO.
