- W4385651574 abstract "Prompt dissemination of clinical trial results is essential for ensuring the safety and efficacy of intracranial neurostimulation treatments, including deep brain stimulation (DBS) and responsive neurostimulation (RNS). However, the frequency and completeness of results publication, and reasons for reporting delays, are unknown. Moreover, the patient populations, targeted anatomical locations, and stimulation parameters should be clearly reported for both reproducibility and to identify lacunae in trial design. Here, we examine DBS and RNS trials from 1997 to 2022, chart their characteristics, and examine rates and predictors of results reporting.Trials were identified using <ext-link ext-link-type=uri xlink:href=http://ClinicalTrials.gov xmlns:xlink=http://www.w3.org/1999/xlink>ClinicalTrials.gov</ext-link>. Associated publications were identified using <ext-link ext-link-type=uri xlink:href=http://ClinicalTrials.gov xmlns:xlink=http://www.w3.org/1999/xlink>ClinicalTrials.gov</ext-link> and <ext-link ext-link-type=uri xlink:href=http://PubMed.gov xmlns:xlink=http://www.w3.org/1999/xlink>PubMed.gov</ext-link>. Pearson's χ2 tests were used to assess differences in trial characteristics between published and unpublished trials.Across 449 trials, representing a cumulative cohort of 42,769 patient interventions, there were 37 therapeutic indications and 44 stimulation targets. The most common indication and target were Parkinson's disease (40.55%) and the subthalamic nucleus (35.88%), respectively. Only 0.89% of trials were in pediatric patients (11.58% were mixed pediatric and adult). Explored targets represented 75% of potential basal ganglia targets but only 29% of potential thalamic targets. Allowing a 1-year grace period after trial completion, 34/169 (20.12%) had results reported on <ext-link ext-link-type=uri xlink:href=http://ClinicalTrials.gov xmlns:xlink=http://www.w3.org/1999/xlink>ClinicalTrials.gov</ext-link>, and 107/169 (63.31%) were published. ∼80% of published trials included details about stimulation parameters used. Published and unpublished trials did not significantly differ by trial characteristics.We highlight key knowledge and performance gaps in DBS and RNS trial research. Over one-third of trials remain unpublished >1 year after completion; pediatric trials are scarce; most of the thalamus remains unexplored; about one-in-five trials fail to report stimulation parameters; and movement disorders comprise the most studied indications." @default.
