PurposeImaging technology can improve patient outcomes by allowing greater precision in diagnosing and treating patients. However, there is evidence that overuse, underuse, and misuse of imaging services occur. The purpose of this project was to develop evidence-based diagnostic imaging practice guidelines for musculoskeletal complaints for use by doctors of chiropractic and other primary health care professionals.MethodsAn electronic search of the English and French language literature (phase 1) was conducted on several databases. Cross references, and references provided by clinicians, were also used. Independent assessment of the quality of the citations used to support recommendations in the guidelines was performed using the QUADAS, the AGREE,and the SPREAD evaluation tools. A first draft of a diagnostic imaging practice guideline was produced, using the European Commission's Referral Guidelines for Imaging document as a template. Results were sent to 12 chiropractic specialists for a first external review. A modified Delphi process, including 149 international experts, was used to generate consensus on recommendations for diagnostic imaging studies. The reliability of proposed recommendations was further tested on field chiropractors and on a group of specialists both in chiropractic and in medicine in both Canada and the United States. All recommendations were graded according to the strength of the evidence.ResultsThe research procedure resulted in the recommendations for diagnostic imaging guidelines of adult extremity and spine disorders supported by more than 685 primary and secondary citations. High levels of agreement among Delphi panelists were reached for all proposed recommendations. Comments received by specialists were generally very favorable and reflected high levels of agreement with the proposed recommendations, perceived ease of use of guidelines, and implementation feasibility.ConclusionsThese evidence-based diagnostic imaging practice guidelines are intended to assist chiropractors and other primary care providers in decision making on the appropriate use of diagnostic imaging for specific clinical presentations. In all cases, the guidelines are intended to be used in conjunction with sound clinical judgment and experience. Application of these guidelines should help avoid unnecessary radiographs, increase examination precision,and decrease health care costs without compromising the quality of care. All guidelines are documents to be refined and modified regularly with new information and experience.
