Abstract

Background: Spinal disorders are a major public health problem. Appropriate diagnostic imaging is an essential part in the management of back complaints. Nevertheless, inappropriate imaging increases population collective dose and health costs without improving outcome. Purpose: To determine the effects of active implementation of referral guidelines on the number and justification of spine radiography in primary care in one city. Material and Methods: Specified guidelines for spine radiography were distributed to referring practitioners altogether three times during the study period. Educational lectures were provided before the guidelines were taken into use. The guidelines were also made available via the intranet. The number of spine radiography referrals during similar 6-month periods in the year preceding the interventions and the following 2 years was analyzed. Justification of 448 spine radiographs was assessed similarly. Results: After interventions, the total number of spine radiography examinations decreased by 48% (P < 0.001) and that of cervical spine radiography by 46% ( P < 0.001), thoracic spine by 53% ( P < 0.001), and lumbar spine by 47% ( P < 0.001). The results persisted after 1-year follow-up. Before interventions, 24% of the cervical, 46% of the thoracic, and 32% of the lumbar spine radiography referrals were justified. After interventions, only justification of lumbar spine radiography improved significantly, 64% being justified ( P = 0.005). Conclusion: Spine radiography in primary care can be reduced significantly by active referral guideline implementation. The proportion of inappropriate radiography was unexpectedly high. Thus, further education and studies concerning the appropriate use of spinal radiography seems to be needed.
