Study design plays an important role in the quality, execution, and interpretation of biomedical and public health research ( 1вЂ“ 12). This manuscript is meant to provide an overview of study design types, strengths and weaknesses of common observational and interventional study designs. Additionally, each study design has potential limitations that are more severe and need to be addressed in the design phase of the study. Each study design has specific outcome measures that rely on the type and quality of data utilized.

Interventional studies are often prospective and are specifically tailored to evaluate direct impacts of treatment or preventive measures on disease. These include diagnostic accuracy designs, diagnostic cohort designs, and diagnostic randomized controlled trials. An important subset of observational studies is diagnostic study designs, which evaluate the accuracy of diagnostic procedures and tests as compared to other diagnostic measures. Observational study designs include ecological designs, cross sectional, case-control, case-crossover, retrospective and prospective cohorts. Observational study designs, also called epidemiologic study designs, are often retrospective and are used to assess potential causation in exposure-outcome relationships and therefore influence preventive methods.

Each design has its own strengths and weaknesses, and the need to understand these limitations is necessary to arrive at correct study conclusions. There are many study designs to choose from within two broad categories of observational and interventional studies. Its five components located in communities throughout Texas are Baylor College of Dentistry, the College of Medicine, the Graduate School of Biomedical Sciences, the Institute of Biosciences and Technology and the School of Rural Public Health.The appropriate choice in study design is essential for the successful execution of biomedical and public health research. The Texas A&M University System Health Science Center provides the state with health education, outreach and research.

CBHECВ’s strategy is to work with the community, policy makers, and health care professionals. CBHEC is funded through the Texas State Legislature as well as private support from area health care systems and industry. CBHEC delivers health education programs to 19 counties in the greater Coastal Bend. Reiner will take questions from the media as part of the question and answer session after his talk.Д®stablished in 1999, CBHEC is an affiliate of The Texas A&M University System Health Science Center in College Station. WHERE: Corpus Christi Town Club, 800 North Shoreline Blvd., Crystal Room The program will review recent clinical trials in ACS and discuss recent changes to American Heart Association/American College of Cardiology Guidelines, as well as identify evolving clotting-prevention strategies in interventional cardiology. WHAT: CBHECвЂ™s Continuing Medical Education (CME) program will present a CME program to area physicians on Acute Coronary Syndromes (ACS). WHO: The Coastal Bend Health Education Center (CBHEC) will host Jonathan Samuel Reiner, M.D., associate professor of medicine, director-Cardiac Catheterization Laboratory at George Washington University Medical Center, and cardiologist to Vice President Dick Cheney.
