A Biopsychosocial Approach to Diagnosing and Treating AD and MDD in a Learning Health System
Biochemically-mediated changes related to the stress response and immune system may selectively impact susceptible brain regions or functional networks that correspond with many of the cognitive functions that are often affected clinically during depressive episodes \[1, 2\]. Although MRI-based studies have paved a path toward biological validation of Major Depressive Disorder (MDD), particularly in large-scale studies that have shown promise to detect biological subgroups \[3\], financially prohibitive costs, practical inconveniences related to scanning time and frequency, and a lack of ability to translate a patient's image into a clinically meaningful tool (e.g. aid in clinical diagnosis or treatment prediction) \[4\] are impediments toward clinical application. As a consolation, the next steps in research would be to identify individuals with MDD who have abnormal biochemical profiles, trait-like risk symptoms, or persistent cognitive deficits to establish clearer profiles of overall risk for depression. To make precise estimations of illness risk, the patient's clinical status in the course of illness, and treatment progress through a course of treatment, one must collect data across biopsychosocial dimensions of human behavior utilizing tools that can measure specific behavioral patterns alongside an implementation of statistical methods that can measure subtle changes in stress and immune physiology. This can be achieved through a Learning Health System (LHS) \[5-11\] in order to "harness the power of data and analytics to learn from every patient and feed the knowledge of 'what works best' back to clinicians, public health professionals, patients, and other stakeholders to create cycles of continuous improvement" \[10\]. Compared to traditional approaches to clinical research and medical care delivery, LHSs can provide individualized, streamlined, scalable solutions based on cutting-edge science in real-time.
Current Proposal
The proposed study is a real-world exploratory clinical trial of the diagnosis and treatment for AD and MDD using a combinatorial analytic approach through three phases of clinical care in an outpatient clinical setting. Treatment engagement (phase I) will consist of diagnostic clarification through traditional diagnostic frameworks with symptom identification and characterization using written symptom inventories and scales, spoken language from patients, and audio/video recordings from patients. During the treatment period (phase II), symptoms, spoken language, and audio/video recordings will be obtained during and between in-person weekly clinical sessions. Biological samples will be obtained at time of clinically suspected acute anxiety and/or depression and weekly thereafter until remission (defined as six months symptomatic free). If acute anxiety and/or depression recurs, biological samples will be obtained again on a weekly basis alongside weekly treatment sessions. Upon remission, the patients will move into the remission-maintenance period (phase III), which will consist of biweekly to monthly treatment sessions during which symptoms, spoken language, and audio/video recordings will be obtained during and between clinical sessions.
Data Storage
Data
Clinical data will be managed according to standard policies. Physical (as opposed to electronic) research data will be coded stored in a locked filing cabinet in the investigator's dedicated locked offices to protect subject anonymity. Electronic research data (including imaging data) and electronic personally-identifiable health information (ePHI) will be stored on secured servers within the firewall with access permitted by study personnel only. Data will be stored using codes assigned by the investigators. The key to the code will be kept in a separate, secure area.
Samples
Biological samples are not kept onsite at Singula Medical. Results will be published as group data without the use of specific identify identifiers.
Data and sample sharing plan
Data will be linked with other protocols and can be shared with other Singula investigators, in accordance with participant authorization under the consent form. Samples and data, including genomic data, will be shared with collaborating laboratories at Singula Medical or outside of Singula Medical and/or submitted to Singula Medical-designated repositories and databases. Genomic data will be submitted to the following designated repositories:
Data and samples may also be shared with collaborating laboratories or outside of Singula Medical and/or submitted to designated repositories and databases if consent for sharing was obtained. Repositories receiving data and/or samples from this protocol may be open-access or restricted access.
Samples and data will be stripped of identifiers and may be coded ("de-identified") or unlinked from an identifying code ("anonymized"). When coded data is shared, the key to the code will not be provided to collaborators, but will remain at Singula. Data and samples may be shared with investigators and institutions with an Federalwide Assurance (FWA) for the Protection of Human Subjects, or operating under the Declaration of Helsinki (DoH) and reported at the time of continuing review. Sharing with investigators without an FWA or not operating under the DoH will be submitted for prospective IRB approval. Submissions to NIH-sponsored or supported databases and repositories will be reported at the time of Continuing Review.
