United Kingdom physiotherapists injection therapy practice for musculoskeletal complaints: A cross-sectional survey.

BACKGROUND

Physiotherapists in the United Kingdom (UK), who have received additional training can adopt injection therapy for the treatment of musculoskeletal (MSK) disorders.

OBJECTIVES

The objective of this practice survey was to explore (i) the frequency of use of injection therapy by UK physiotherapists for MSK disorders; and (ii) the clinical reasoning for selection of injectate, dose and pre/post injection practice.

DESIGN

Cross-sectional online survey.

METHODS

The online survey was disseminated via social media and professional networks over a 3-month period. Responses to closed multiple choice survey questions were analysed with descriptive data, with reporting of confidence intervals at 95%. Open questions were analysed using content analysis.

RESULTS

The survey received 320 responses. The majority (86.6%, n = 277) used landmark guided approaches. The highest frequency of injections administered were for trigger digits, sub acromial pain and the knee joint. Corticosteroid drugs were widely used (99.7%, n = 319, CI 95% 98 to 100) with Triamcinolone (Kenalog) being the most frequently utilised for both joints (58.8%, n = 160, 53 to 65) and soft tissues (46.3%, n = 126, 40 to 52). Drug choice was largely based on availability in clinic (47.1%, n = 128, 41 to 53). Drug doses for common injection sites varied among the respondents with variation also evident in pre and post-injection practice.

CONCLUSION

Marked variation across some elements of injection therapy practice was evident. Notable differences in corticosteroid preparation used, the doses of drug injected, and the use of local anaesthetic were reported by respondents. Injecting physiotherapists should endeavour to ensure practice is aligned to best available evidence.
