Abstract
Objective: In the Brazilian public national healthcare system, botulinum toxin type A has traditionally been the sole treatment option for patients with dystonia. However, as of October 2022, Deep Brain Stimulation (DBS) garnered positive recommendations for the condition. This study aims to assess the cost-effectiveness of DBS in treating adults with generalized and cervical dystonia within the Brazilian healthcare context, considering its recent inclusion.
Methods: A systematic review identified randomized controlled trials (RCTs) assessing DBS efficacy in treating adults with generalized and cervical dystonia. Two cost-utility analyses compared the cost-effectiveness of DBS plus the Best Clinical Practice (BCP) to BCP alone. Markov models, which included three health states (no clinical improvement, clinical improvement, and death), employed a one-year cycle and a lifetime horizon. The study utilized both one-way and probabilistic sensitivity analyses.
Results: Two RCTs, one for each condition, revealed superior clinical improvement with DBS when compared to sham simulation. The Incremental Cost-Utility Ratio (ICUR) was $ 1,121.66 for generalized dystonia and $4,556.50 for cervical dystonia. Effectiveness discount rates and age at surgery were identified as influential parameters. In 1,000 Monte Carlo simulations, 99.9% of the ICUR values for generalized dystonia and 74.2 % for cervical dystonia fell below the cost-effectiveness threshold in Brazil ($8,146.64 per QALY).
Conclusions: From the perspective of the Brazilian public health system, the combination of DBS and BCP appears to be cost-effective for the treatment of both generalized and cervical dystonia when compared to BCP alone.
期刊介绍:
World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The journal''s mission is to:
-To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care.
-To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide.
-To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients.
Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
