Advice for before, during, and after injection
Patients need to be “fully informed of the nature of the procedure, the injectable used, and potential effects – benefits and risks – [and] informed consent should be obtained and documented,” said Dr. Usón, outlining the first recommendation. “That seems common,” she said in the interview, “but when we did the survey, we realize that many patients didn’t [give consent], and the doctors didn’t even ask for it. This is why it’s a very general statement, and it’s our first recommendation. The agreement was 99%!”
The recommendations also look at the optimal settings for performing injections, such as providing a professional and private, well-lighted room, and having a resuscitation kit nearby in case patients faint. Accuracy is important, Dr. Usón said, and imaging, such as ultrasound, should be used where available to ensure accurate injection into the joint. This is an area where further research could be performed, she said, urging young rheumatologists and health professionals to consider this. “Intra-articular therapy is something that you learn and do, but you never really investigate in it,” she said.
One recommendation states that when intra-articular injections are being given to pregnant patients, the safety of injected compound must be considered, both for the mother and for the fetus. There is another recommendation on the need to perform IA injections under aseptic conditions, and another stating that patients should be offered local anesthetics, after explaining the pros and cons.
Special populations of patients are also considered, Dr. Usón said. For example, the guidance advises warning patients with diabetes of the risk of transient glycemia after IA glucocorticoids and the need to monitor their blood glucose levels carefully for a couple of days afterward.
As a rule, “IAT is not a contraindication to people with clotting or bleeding disorders, or taking antithrombotic medications,” she said, unless they are at a high risk of bleeding.
Importantly, the recommendations cover when IAT can be performed after joint replacement surgery (after at least 3 months), and the need to “avoid overuse of injected joints” while also avoiding complete immobilization for at least 24 hours afterward. The recommendations very generally cover re-injections, but not how long intervals between injections should be. When asked about interval duration after her presentation, Dr. Usón said that the usual advice is to give IA injections no more than 2-3 times a year, but it depends on the injectable.
“It wasn’t our intention to review the efficacy and the safety of the different injectables, nor to review the use of IAT in different types of joint diseases,” she said. “We do lack a lot of information, a lot of evidence in this, and I really would hope that new rheumatologists start looking into and start investigating in this topic,” she added.
Recommendations will increase awareness of good clinical practice
“IA injections are commonly administered in the rheumatology setting. This is because [IA injection] is often a useful treatment for acute flare of arthritis, particularly when it is limited to a few joints,” observed Ai Lyn Tan, MD, associate professor and honorary consultant rheumatologist at the Leeds (England) Institute of Rheumatic and Musculoskeletal Medicine.
IA injection “also relieves symptoms relatively quickly for patients; however, the response can be variable, and there are side effects associated with IA injections,” Dr. Tan added in an interview.
There is a lack of universally accepted recommendations, Dr. Tan observed, noting that while there might be some local guidelines on how to safely perform IA injections these were often not standardized and were subject to being continually updated to try to improve the experience for patients.
“It is therefore timely to learn about the new EULAR recommendations for IA injections. The advantage of this will be to increase awareness of good clinical practice for performing IA injections.”
Dr. Tan had no relevant conflicts of interest.
