Background: The introduction of the electronic health record (EHR) has improved the collection and storage of patient information, enhancing clinical communication and academic research. However, EHRs are limited by data quality and the time-consuming task of manual data extraction. This study aimed to use process mapping to help identify critical data entry points within the clinical pathway for patients with vestibular schwannoma (VS) ideal for structured data entry and automated data collection to improve patient care and research.

Article Synopsis
  • New diagnostic criteria for NF2-related schwannomatosis were established in 2022, leading to an updated prevalence study in the UK, which focused on the rate of de novo NF2 cases.
  • A total of 1,084 living NF2 patients were identified, indicating a prevalence of 1 in 61,332, with a striking 72% of cases being de novo, many of which were mosaic.
  • The findings also revealed that nonsense variants were most common (24.8%), while missense variants had a higher familial association (56%), emphasizing the importance of patient databases for accurate genetic counseling.

Background: Phaeochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumours. Pathogenic variants have been identified in more than 15 susceptibility genes; associated tumours are grouped into three Clusters, reinforced by their transcriptional profiles. Cluster 1A PPGLs have pathogenic variants affecting enzymes of the tricarboxylic acid cycle, including succinate dehydrogenase.

 An operative workflow systematically compartmentalizes operations into hierarchal components of phases, steps, instrument, technique errors, and event errors. Operative workflow provides a foundation for education, training, and understanding of surgical variation. In this Part 1, we present a codified operative workflow for the retrosigmoid approach to vestibular schwannoma resection.
