Current and Prospective Use of Musculoskeletal Diagnostic Ultrasound Imaging at Chiropractic Teaching Institutions: A Worldwide Survey of Diagnostic Imaging Staff.

OBJECTIVE: The purpose of this study was to survey the use of musculoskeletal diagnostic ultrasound imaging (MSK-DUSI) at chiropractic educational programs worldwide and to elicit opinions of academic diagnostic imaging staff of its prospective use at their teaching institutions. METHODS: An electronic questionnaire was delivered in 2014 using SurveyMonkey and notifications were disseminated by e-mail to 127 diagnostic imaging staff at chiropractic programs worldwide. The questionnaire consisted of 27 items using multiple-choice, Likert-type, and open-ended questions. Descriptive statistics were used for basic demographic data and the results of the numerical scales used in each item. RESULTS: Fifty-nine respondents (46.5%) from 24 (24/41) chiropractic programs returned questionnaires. The reported use of MSK-DUSI at chiropractic programs is low (n = 5/24); however, respondents from 9 institutions stated that it is planned to be implemented. Few respondents stated they had formal MSK-DUSI qualifications (4/59); however, 7 respondents stated they were in the process of becoming certified. Most respondents expressed an interest in the prospect of incorporating MSK-DUSI at their chiropractic program. Sixty-five percent stated that chiropractic programs should provide MSK-DUSI training to chiropractic students, and 75% of respondents stated that chiropractic programs should be providing accredited postgraduate MSK-DUSI courses. CONCLUSIONS: The current use of MSK-DUSI among chiropractic programs that responded to this survey is low. The opinions of diagnostic imaging staff who responded suggest a positive attitude to its use and possible growth in its use if foundational work, including gaining funding, accreditation, and acceptance of within the scope of chiropractic practice, is undertaken.

The accuracy of diagnostic ultrasound imaging for musculoskeletal soft tissue pathology of the extremities: a comprehensive review of the literature.

Musculoskeletal diagnostic ultrasound imaging (MSK-DUSI) has been growing outside the traditional radiology speciality. Increased use of this technology has been reported in several healthcare settings, however an apparent gap in the knowledge of the accuracy of this diagnostic technology indicated a review was warranted. We undertook a structured review of the literature to assess the accuracy of MSK-DUSI for the diagnosis of musculoskeletal soft tissue pathology of the extremities. An electronic search of the National Library of Medicine's PubMed database (1972 to mid-2014) was conducted. All relevant systematic reviews of diagnostic studies, all diagnostic studies published after the date of the latest systematic reviews and relevant diagnostic studies outside the scope the systematic reviews that directly compared the accuracy of MSK-DUSI (the index test) to an appropriate reference standard for the target condition were included. A fundamental appraisal of the methodological quality of studies was completed. The individual sensitivity, specificity and likelihood ratio data were extracted and entered into diagnostic accuracy tables. A total of 207 individual studies were included. The results show that MSK-DUSI has acceptable diagnostic accuracy for a wide spectrum of musculoskeletal conditions of the extremities. However, there is a lack of high quality prospective experimental studies in this area and as such clinicians should interpret the results with some caution due to the potential for overestimation of diagnostic accuracy.
