Cost-effectiveness of treatments for temporomandibular disorders: biopsychosocial intervention versus treatment as usual.
BACKGROUND The authors conducted a r and omized clinical trial to evaluate the cost-effectiveness of a biopsychosocial intervention with patients who are at high risk ( HR ) of progressing from acute to chronic TMD-related pain . METHODS The authors classified 96 patients with acute TMD ( less than six months ' duration ) as HR according to a predictive algorithm and r and omized them into an early intervention ( EI ) or a nonintervention ( NI ) group . The NI group received a biopsychosocial treatment that included cognitive behavioral skills training and biofeedback . Both groups were followed up for one year . The authors collected TMD cost data throughout the year . RESULTS The authors found that the EI group spent significantly fewer jaw-related health care dollars , relative to the NI group , from intake to the one-year follow-up . CONCLUSION AND CLINICAL IMPLICATION S The reduced jaw-related health care expenditures for patients in the EI group compared with expenditures for patients in the NI group at one year suggest that an early biopsychosocial intervention is a cost-effective measure in dealing with often unnecessarily costly TMD-related pain
