An Observational Study of Patients Living With Chronic Neurological Diseases

Study Overview

Brief Summary
-----------------
TARGET-NEURO is an observational research study to conduct a comprehensive review of outcomes for patients living with chronic neurological diseases: Alzheimer's disease and related dementia (ADRD), mild cognitive impairment (MCI), Parkinson's disease (PD), and multiple sclerosis (MS).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To characterize the natural history of disease in patients living with chronic neurological diseases including ADRD, MCI, PD, or MS | A detailed analysis of available demographics (age, race, sex, country of birth, insurance status), medications, co-morbidities, and medical history from sites across the US will inform the profile for this patient population. Data from retrospective and prospectively collected medical records will be curated and analyzed to characterize disease natural history and current treatment paradigms. These data may also establish incidence rates of events of special interest. Collection of prospective medical records for each patient enables the continuation of these analyses longitudinally for changes and progression. Part of the characterization of disease or living with a chronic disease may also be informed by patient reported outcome (PRO) measures and care partner surveys. | 15 Years | 
| To assess safety and effectiveness of disease treatments and treatments for complications of patients receiving various treatments, effectiveness of treatment, and medical events that develop while receiving treatment for ADRD, MCI, PD, or MS. | The study will evaluate the characteristics of patients receiving various treatments, effectiveness of treatment, and medical events that develop while receiving treatment for ADRD, MCI, PD, or MS. Interval disease and medical events may vary depending on the patient's stage and type of disease and extent of co-morbidities. The progression of pre-existing co-morbidities and variances across populations will also be evaluated. The type, dose and duration of disease-specific therapies will be closely followed with a goal of monitoring treatment paradigms and various combination regimens for clinical response and disease stabilization/progression. | 15 Years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate provider management practices in the treatment of patients living with ADRD, MCI, PD, or MS | Health care provider type, clinic setting, reason for initiating/not initiating/adjusting dosing of treatments, reason for discontinuing/switching treatments, and monitoring outcomes on and off treatment, will be captured as available in the provided EHR and/or through linked data. Disease-specific quality measures will be selected and evaluated | 15 Years | 
| To evaluate longitudinal and patient and care partner reported outcomes in patients with ADRD, MCI, PD, or MS, including care partner burden and quality of life. | Longitudinal clinical outcomes and disease progression will be assessed. Self and proxy-reported patient health measures collect information directly from patients or their informants to measure physical, mental, and social health. These measures can help clinicians better understand how the disease state and/or various treatments affect what patients are able to do and the symptoms they experience beyond what is typically derived and reported in the EHR as part of traditional clinical evaluations. The information can also be used to help patients make informed decisions about their healthcare and treatment options. Care partner surveys can help define the prevalence and needs of care partners who provide support and care to people living with ADRD, MCI, PD, and MS. | 15 Years | 
| 3. To select and evaluate quality of care measures for patients living with ADRD, MCI, PD, or MS | Identify deficiencies and best practices in care of patients living with neurological diseases Develop a technology infrastructure to evaluate quality measures to support clinicians and clinical decision making | 15 Years |
