Patient Demographics

With seven health care systems treating over 10 million patients, PaTH gives researchers the opportunity to work with and learn from larger and more diverse populations than would be available in any single system.

For instance, sites with smaller percentages of young patients, such as Penn State and Temple, can benefit from their partner sites’ higher percent of patients under 18. Meanwhile, the other sites gain Penn State’s high percent of patients who are 65 and older and Utah’s high percent of patients aged 18 to 44.

Likewise, Temple University offers a higher percent of African American patients than its partner sites, while the University of Utah brings a higher percent of Hispanic and Latino patients to studies.

By combining populations, the PaTH Network is able to increase the quantity, quality, and diversity of patient data available to researchers and therefore strengthen their study findings.
