VICIEM is a clinical and laboratory databank for patients with Inborn Errors of Metabolism (inherited metabolic diseases).  VICIEM consolidates disparate records into a single unified electronic database and includes data on patients treated at the Royal Children’s Hospital (RCH), Melbourne, since 1970.  RCH is a tertiary centre for the diagnosis and management of patients with inherited metabolic diseases from Victoria and Tasmania.  By meticulously collating longitudinal clinical data and outcomes of patients with inherited metabolic disorders, and their causative mutations and biochemical derangements, we aim to develop a better understanding of the natural history of these disorders and provide information that can aid in improving prognostication, effectiveness of newborn screening, cost and effectiveness of treatment (including dietary manipulations), and possibly analyses of the correlation between mutations and clinical outcome, where applicable. It is hoped it will serve as an important step towards devising evidence-based therapies.

Please note: VICIEM is not a traditional longitudinal cohort study, but rather a longitudinal databank that includes retrospective data, based on medical records (including teacher and primary caregiver reports within those medical records where applicable). Recruitment of newly diagnosed patients is ongoing. With the implementation of the new campus EMR system, newly diagnosed patients are partially entered into the VICIEM database for identification purposes (including information pertaining to birth, demographics, diagnosis and presentation).
