Celebrating over 30 years of independent research

Medical Technology & Practice Patterns Institute (MTPPI) is a nonprofit organization established in 1986 to conduct research on the clinical and economic implications of health care technologies. MTPPI’s research is directed toward the formulation and implementation of local and national health care policies.

With extensive investigator experience in both the public and private sectors, MTPPI’s staff designs, implements, and conducts a full range of healthcare research and technology development activities. Our staff includes statisticians, epidemiologists, economists, programmers, biomedical engineers, and policy analysts. We specialize in using big data to conduct “real-time”, “real-world” studies that are both affordable and useful for healthcare stakeholders.

“By enhancing the methods for conducting Comparative Effectiveness Research, MTPPI will provide information that will ultimately help people make more fully informed health and healthcare decisions.”
