Authors' objectives:

This study aims to determine the effectiveness and adverse effects of deep brain stimulation (DBS) in the treatment of symptoms of idiopathic Parkinson's disease (PD), essential tremor, and primary dystonia, and to conduct an economic analysis if evidence for effectiveness is established.

Authors' results and conclusions: There is level 1b evidence that bilateral DBS of the subthalamic nucleus is effective in the short-term control of advanced parkinsonian symptoms, and there is level 3a evidence that the effect is sustained for at least 5 years. There is Level 3a evidence that DBS of the thalamus is effective in the control of tremor in patients with essential tremor and PD for at least 6 years. There is level 3a evidence that bilateral DBS of the globus pallidus is effective in the control of symptoms of primary dystonia for at least 1 year.
Authors' recommendations: According to the estimates of prevalence and evidence of effectiveness, there is a shortfall in the number of DBS procedures currently done in Ontario for drug-resistant PD, essential tremor, and primary dystonia. Since complication rates are lower if DBS is performed in specialized centres, the number of sites should be limited. The cost per procedure to institutions with the expertise to undertake DBS and the human resource considerations are likely to be limiting factors in the further diffusion of DBS.
