Biostatisticians’ Goals When Working with You
  • Enhance the integrity and validity of your study

  • Ensure the design has strong internal validity and, if possible, external validity

  • Specific aims

  • Measurement quality

  • Sampling plan

  • Randomization procedures

  • Data management

  • Statistical power

  • Appropriate analyses

Start Working with Us Early and Always!
  • Early in proposal development stage is the best

  • Studies have problems, that is OK

    • Definitely consult with a statistician before making changes and hoping for the best

    • If biostatisticians are active collaborators on the project, they can sometimes see trouble ahead and help to prevent or alleviate it

  • Involve us in database design and data management approach

  • We are an important part of the DSMB

  • We love to do complex analyses but in reality that is a very small part of how we spend our time on a project

  • Role of Co-Investigator on the proposal

  • Biostatistician role in proposal development

    • Align aims, methods, and analyses

    • Conduct preliminary study analyses, if needed

    • Conduct power analyses

    • Write the analysis section of proposals

  • Review the budget to ensure support for data management, data cleaning, and analyses

  • We are able to help depending on the scope of the request

  • Best approach

    • Meet with Nancy Perrin to discuss what is needed, devise analysis plan, and timeline

    • Work will be assigned to a Biostatistics Core member based on interest, expertise, and workload

  • Depending on the amount involvement in the project, the biostatistician may be considered for co-authorship

  • Monthly seminars

    • Measurement

    • Data Management

    • Mediators and Moderators

    • Adaptive Trials

    • Pragmatic Trials

    • Cluster Randomized Trials

    • Observational Methods

    • PROMIS Measures

  • Considering having mini-courses that go more in-depth on certain topics

    • Possible credit for student

  • PhD NRSA Proposal Support

    • Student works with one Biostatistics Core member on the proposal

    • The Student, Adviser, and Biostatistician reach agreed upon aims, research design, and analysis plan

    • Help with power analyses, writing of the analysis section

    • Need to begin working together at least 45 days prior to the submission date

  • PhD Dissertation

    • Goal is to have students participate in the data management training and working group so they can do their own data management under guidance

    • If analyses are complex, it is recommended a Biostatistics Core member is on the committee

    • If no biostatistician on the PhD committee, Biostatistics Core will provide basic consultation

  • DNP Students

    • The DNP program has statistical support integrated into the course of study. DNP students should direct requests for statistical support to the faculty for 817 and/or 818 and their DNP advisors

  • Train project staff in data management, data cleaning, and data integrity (TBD)

  • Hold monthly or bimonthly working group of project staff to discuss issues in recruitment, retention, and data management (TBD)

  • Develop a pool of trained and mentored statistical analysts that can be written into grants (NP)

  • 3-4 students who have demonstrated experience with data management and data analysis

  • After completing a test project, students are assigned to a project and mentored by a Biostatistician

  • Students and Biostatistics Core meet together to discuss ongoing projects

  • Students may be able to help with analyses of manuscripts and presentations when there is no funding available

  • Could satisfy a Research Residency
