Biostatistics and Data Science Core
The Biostatistics and Data Science (BDS) Core provides CFAR investigators with statistical consultation and collaboration for exploratory investigations and proposal development, and data management and informatics expertise for research planning.
The Core Director is Dr. Susan Ellenberg, Professor of Biostatistics at the University of Pennsylvania. The Core Co-Director is Dr. Pamela Shaw, Associate Professor of Biostatistics.
Dr. Alisa Stephens, Assistant Professor of Biostatistics at the University of Pennsylvania, is a Core Investigator. Mr. Chris Helker, Director of Clinical Data Management at Penn’s Clinical Research Computing Unit, is the Core representative for data management needs.
Drs. Ellenberg and Shaw, together with Core Investigator Dr. Alisa Stephens, Assistant Professor of Biostatistics, and a supporting data analyst, provide consultation and collaboration on study design and analysis issues requested via the Core. Drs. Ellenberg, Shaw and Stephens all have substantial experience and expertise in designing, conducting and analyzing data from clinical trials as well as laboratory studies and observational studies. Dr. Shaw’s ongoing statistical research program addresses the analysis of data that include error-prone or misclassified covariates, such as exposures and outcomes derived from the EHR, and/or outcomes in HIV-related epidemiological and clinical investigations.
Every attempt will be made to link investigators with statistical collaborators who have particular expertise in the methods relevant to the types of data to be generated in their study; other faculty and research staff may become involved in CFAR projects to provide specialized expertise when needed
- Statistical Expertise
- Database Design and Management Expertise
- Using the Clinical Core Database and Specimen Repository
- Biostatistics Training
The Biostatistics and Data Science Core offers advice to CFAR Investigators on study design and data analysis issues. It also provides statistical collaborations for research funding applications, and analytical help for small studies without formal funding for statistical collaboration. Areas of application include:
- laboratory and animal studies
- clinical studies relating to prognostic characteristics and disease course
- clinical trials of therapeutic and preventive regimens
- analysis of EHR data
To request consultation regarding statistical issues, please contact Dr. Susan Ellenberg at firstname.lastname@example.org.
Database Design and Management Expertise
Informatics expertise is provided by staff of the Clinical Research Computing Unit (CRCU) and covers all aspects of data management, including:
- Proposal development and submission coordination
- Database design, construction and management
- Development of data collection instruments/case report forms
- Data quality assurance/control
- Data mining and integration (CFAR database and Penn Data Store)
To request any of these services, contact Chris Helker at email@example.com.
Clinical Core Database and Specimen Repository
The Penn CFAR Biostatistics and Data Science Core maintains and facilitates access to a clinical care database for use in studying the epidemiology of HIV/AIDS, for evaluating feasibility of intervention studies, and for facilitating conduct of such studies. The Clinical Core Database and Specimen Repository can be used to identify potential subjects for study or can be used as a basis for independent clinical investigation.
Data and samples available to investigators include:
- Biological Specimens
- Medical History
- Previous Antiviral Treatments
- Present Antiviral Treatments
- Sexual History
- Adherence Questions
- Alcohol and Drug Use
- Hepatitis Treatment
- CES-D (Center for Epidemiologic Studies-Depression)
- Clinical Laboratory Measures
To access the database please follow the steps below:
1. Please contact Amy Onorato to receive a username and password.
2. Once your username and password have been received, Click here to access the database
To identify the data that are available, you may download the Case Report Form (CRF) that patients are given at intake and the Follow-up CRF that is done at subsequent visits.
Consultations, queries of the Databases, and access to specimens from the Specimen Repository are provided to CFAR investigators and their collaborators by request.
For more information, to request consultation, or to request training on accessing the database, please contact Ted Barrell, CRCU Data Manager, at firstname.lastname@example.org Phone: 215-573-5486
Core G biostatisticians are available to make introductory presentations on biostatistical concepts and methods that are appropriate for faculty and fellows working in other Core areas. These presentations are routinely made to Virology faculty and fellows in spring semesters and can be presented to other groups as well. Click here for a PDF of a prior training seminar.
