A system for processing patient health information (PHI) protects the confidentiality of PHI to achieve regulatory compliance. The PHI contains patient medical data and associated patient identification data. A de-identification agent extracts patient medical data and separates from all identification data to create de-identified patient data. A key is generated that allows subsequent reassociation of the patient medical data and the patient identification data. The de-identified patient data base may be queried for patient screening purposes. Patient queries are processed only if the study or patient screening has been authorized by appropriate authorities, such as an internal review board. Patients whose medical characteristics conform with the patient query are selected for possible use in a study. If re-identification of the selected patients is necessary, and authorized, the key may be used to provide the necessary reassociation. A data log records all access to patient data.

According to one aspect of the invention, health insurance claim data for a first group of individuals is obtained to generate a training corpus, including a training set of claim data and a holdout set of claim data. The first group of individuals represents enrollees of one or more first health insurance plans and the health insurance claim data represents historic insurance claim information for each individual in the first group. A Bayesian belief network (BBN) model is created by training a BBN network based on the training set of claim data using predetermined machine learning algorithms. The BBN model is validated using the holdout set of claim data. The BBN model, when having been successfully validated, is configured to identify at least one of individuals with risk for a disorder and individuals with risk who are most likely to benefit from intervention and treatment for the disorder.

A computer-implemented method of tracking patient data in a clinical trial is provided. The clinical trial has one or more investigative sites which perform patient screening and enrollment for the clinical trial, one or more diagnostic sites which perform analysis on one or more patient diagnostic tests ordered by an investigative site and generate analysis results, and a centralized data center in electronic communication with the one or more investigative sites and the one or more diagnostic sites.

A predictive system and method for using a physician's existing patient database to more effectively and efficiently identify potential candidates for medical treatments or clinical research trials. The system and method includes an automated three-tiered qualification process using information about a specific medical treatment received from a company looking for potential candidates for the medical treatment wherein potential candidates are initially prequalified by comparing the information about the medical treatment to the information contained in a physician's patient database. The potential candidates that are identified by the first tier of the qualification process then answer additional questions from a patient screening survey. Finally, additional questions from a physician consultation questionnaire are completed by the referring physician's office. If a potential candidate passes all three tiers of qualification, the potential candidate is then passed to the company looking for potential candidates for the medical treatment.
