Program Policies

 Biostatistics Program at Arkansas Children’s Hospital Campus

Overview of Policies


The mission of the Biostatistics Program is to provide outstanding statistical and informatics support to clinical, applied, translational, and biomedical researchers while advancing the reputation and research capacity of the Arkansas Children’s Research Institute (ACRI), Arkansas Children’s Hospital (ACH), the University of Arkansas for Medical Sciences (UAMS) Department of Pediatrics (DOP) and ACH-based UAMS faculty.

Support Provided

Protocol Development

The program provides assistance with protocol development. This support includes framing and refining of research questions and study design. This also includes creating a statistical analysis plan (SAP), developing a randomization plan, determining/justifying sample size, and developing a data management and data collection plan. A biostatistician should be involved early  in the grant submission process.

Grant Development

The program provides grant planning for both intramural and extramural grant development.  This includes research design development as well as creating a statistical analysis plan (SAP), developing a randomization plan, determining/justifying sample size, and developing a data management and data collection plan. A biostatistician should be involved early  in the grant submission process.

Database Support

The program provides comprehensive database design and support to produce quality improvement, research and clinical databases and surveys.  Various database systems, including REDCap, are available to fit the specific needs of your project.  Click database support for information about database services and policies.

Data Retrieval

The program provides data retrieval from the MEDITECH system.  If data retrieval is in preparation of research, the Use of PHI in Activities Preparatory to Research form must be submitted to ACHRI Regulatory Compliance.

Statistical Data Analysis

The program provides statistical analysis and interpretation of results. Assistance in the preparation of results for grants, manuscripts, and presentations is also provided.

Manuscript Preparation

The program provides assistance with the preparation of statistical results for manuscripts.

Teaching & Journal Clubs

The program provides teaching and journal club support through seminars and courses on various statistical topics.


Project Funding

Project support from the Biostatistics Program can be funded through General Research Funds, Division/Section Funds, Discretionary Funds, Specialized Purpose Funds, Endowed Chair Funds, Intramural Grant Funding, Extramural Grant Funding, and other funds.  There is no charge for the initial consultation.  On a limited basis, projects can be funded by institutional support subsidized through the DOP, ACH, and ACHRI.  Grant development is usually provided through institutional support.

Institutional Support

Institutional support allows the program to offer comprehensive biostatistics and database support for all types of research activities and also supports growth and expanded expertise to enhance the Biostatistics Program.

Requests for subsidized assistance will only be considered after all other funding sources have been fully explored. All requests for institutional support are submitted through the Biostatistics Program and will be routed to section chief and the appropriate administrative office for approval and signatures.

Percent Effort Cost Basis

Biostatistics Program personnel can be funded through grants and contracts for appropriate percent efforts (e.g. 5% Biostatistics Faculty, 10% Biostatistics Staff, and 10% Informatics Staff) based upon the defined work scope. This funding is usually the result of the Biostatistics Program support provided during grant development, which is provided through institutional support.

For extramural grants, the minimum percent effort for biostatistics faculty is generally 5% annually. The biostatistics staff needs are negotiated on a case by case basis with approval by the Biostatistics Program Director. Note: Pre-approval must be obtained from the director before including faculty or staff on a grant application submission.

Any division within the DOP can directly support the Biostatistics Program faculty and staff. Divisional long-term support (for at least a 6 month period) qualifies for a 20% discount in salary and fringe benefits,provided the support is arranged in advance of the work performed.

Hourly Cost Basis

Support can be funded using an hourly cost basis. Cost estimates will be provided by the Program Manager after an initial project consultation with a biostatistics faculty supervisor.  There is no charge for the initial consultation.  Effective January 1, 2013, the hours worked will be billed monthly at the following hourly rate:

      Biostatistics Faculty: $120 per hour

      Biostatistics Staff: $75 per hour

      Informatics Staff: $75 per hour

Other Policies/Guidelines


Co-authorship is independent of funding and should be based on the level of participation. General guidelines can be found here. If the program’s faculty and/or staff make a contribution that warrants authorship based on the guidelines, they should be listed as co-author.

IRB Application

Any biostatistics faculty collaborating on a research proposal requiring IRB approval should be considered as co-investigator or sub-investigator on the IRB application. All program personnel maintain current human subject research credentials with the IRB. Investigator status (e.g. co-investigator, sub-investigator, key personnel) should be determined based on the level of participation.

For projects involving research, please provide the protocol, approval letter, or determination form from the IRB or IACUC. Please note that if at any time during the course of your support IRB approval expires, all access and work on the project will be suspended until approval is reinstated.

Grant Application

Any biostatistics faculty collaborating on the development of a grant application should be considered as co-investigator on the application, regardless of funding source (e.g. intramural or extramural). For CUMG applications, percent effort for faculty listed as co-investigator are provided at no charge and are funded with support from DOP/ACH/ACHRI. However, biostatistics staff and informatics staff should be listed in the CUMG budget, as needed.  Please let the Biostatistics Program Manager know outcome of the grant application (e.g. awarded, not awarded) in a timely fashion.


For anything with a deadline (grants, abstracts, etc.), the program recommends at least eight weeks of collaboration prior to the submission date. This allows the program to manage staffing levels and ensure that there is time to provide input on design and analysis issues.

Biostatisticians need sufficient time to develop a strong grant for submission. For R21 grant applications, it is best to contact the Biostatistics Program as soon as possible, but at least three months prior to the deadline is required. For R01 applications, contact the program six to eight months prior to the deadline. For CUMG and ABI applications, the program requires at least four weeks of collaboration prior to the deadline (e.g. contact by February 1 for a March 1 deadline).

Outside Biostatisticians

It is understood that existing projects may receive statistical support from other sources outside of the DOP/ACH/ACHRI Biostatistics Program. However, it is expected that all future projects (new or extended) requiring biostatistical support on ACH’s campus collaborate with faculty and staff within the Biostatistics Program at DOP/ACH/ACHRI. If there is a need to use an outside biostatistician (external to ACH’s campus), please discuss this with the Biostatistics Program Director, Dr. Mario Cleves. This requirement may be waived at the discretion of Dr. Richard Jacobs.

Request Support

To request support from the Biostatistics Program, complete a Pediatric Biostatistics Project Registration Request.

After support is requested, an initial consultation will be set up by the Biostatistics Program.  If the investigator requesting support is not the Principal Investigator (PI) of the project, the PI should be included in the initial meeting and on all future correspondence.
