Our Services

Design support

Includes producing power calculations, determining sample size, designing studies that minimize the effects of measurement and experimental error, and identifying appropriate methods for data collection, summary and analysis.

Adaptation and development

Includes quantitative research that will produce improved methods and procedures to collect, manage, analyze and interpret biomedical data.  This usually occurs during a long-term collaboration between a UTMB researcher and a member of the Office of Biostatistics.

Data base design

Includes developing project specific systems for data acquisition, scheduling, and modification. Data management includes maintaining data bases and preparing data bases for analysis. Data analysis includes identifying and applying appropriate numerical procedures to allow valid statistical inferences.

Special services

Are available to assist with the conceptualization, formulation, design, use and codification of these data gathering tools.  Pilot testing, training, operational evaluation and analytic support can be obtained on a project specific basis.

Software support and other services

The OBIOS provides support for the computer package SAS® at UTMB. The OBIOS is the point of contact and provides expert support campus-wide for SAS®, a statistical software with extensive data management capabilities. The OBIOS also maintains and supports nQuery Advisor®, a software package for computing power and sample size; ArcGIS, a mapping and spatial analysis program; and TreeAge, a visual modeling tool for building and analyzing decision trees for cost-effectiveness analyses.
The OBIOS maintains an insurance claims data base, Clinformatics DataMart, which contains the medical and pharmacy claims for more than 56 million enrollees, for academic training and research purposes. This database offers numerous opportunities for researchers who are interested in population studies. However, this type of database may require experienced programming, study design and analytic support. Contact Dr. Baillargeon (jbaillar@UTMB.edu) for more information.
