Tumor imaging instruction and assessment at chiropractic colleges in North America: a pilot study with implications for National Board of Chiropractic Examiners content.

Objective: This pilot study tested a survey instrument pertaining to the instruction and assessment of tumor imaging in chiropractic training programs. The secondary purpose was to gather data regarding credentials of lead instructors, textbook and resource use, and tumors taught and assessed.

Methods: An electronic survey was distributed to lead tumor imaging instructors at all chiropractic colleges in the United States and Canada. A focus group of tumor imaging instructors was conducted to clarify ambiguous data.

Results: Diplomate status with the American Chiropractic Board of Radiology was held by 87.5% of the instructor respondents. There were similarities in course content and assessment across institutions. A total of 26 tumors were considered clinically significant by more than 65% of instructors, 9 tumors were identified as not clinically significant by more than 65%, and 4 tumors were considered clinically significant by 35% to 65% of instructors. There was correlation between those instructors who evaluated on various tumors and those who feel it is important to evaluate such tumors (r = 0.94, p < .001). The focus group addressed the 4 equivocal tumors and recommended 3 be added to the list of clinically insignificant tumors.

Conclusion: The survey instrument is ready to be used to conduct a study of all clinical areas of the chiropractic curriculum. A total of 12 tumors were recommended for removal from National Board of Chiropractic Examiners tests. The authors recommend that the Academics Committee of the American Chiropractic Board of Radiology share information regarding learning libraries to allow for a richer learning experience across all campuses.
