Reducing roentgenography use. Can patient expectations be altered?

Abstract

Many roentgenographic tests, including lumbar spine roentgenograms, may be overutilized. We examined the psychological, functional, and financial consequences of omitting spine films for patients with back pain with little risk of underlying systemic illness. Patients were randomized to receive immediate roentgenograms (n = 49) or a brief educational intervention, with roentgenography only for failure to improve (n = 52). After three weeks, 73% of the roentgenography group believed "everyone with back pain should have an x-ray," vs 44% of the education group. After three months, although 31% in the education group had received roentgenograms, overall radiology charges were still far less than those of the roentgenography group. No serious diagnoses were missed, and symptom resolution, functional improvement, and satisfaction were similar for the two groups. Thus, eliminating or delaying spine films need not cause anxiety, dissatisfaction, or dysfunction. This strategy may modify future expectations of roentgenography use and reduce health care costs.
