Data Resources at CPCE

The Center for Pediatric Clinical Effectiveness (CPCE) gathers and manages pediatric health information as complex data resources that can be accessed or utilized by our researchers to answer clinical effectiveness research questions.

The Healthcare Analytics Unit

The Healthcare Analytics Unit (HAU), a core facility of CHOP’s Research Institute that is co-directed by CPCE and PolicyLab, administers these resources. HAU’s staff has expertise in managing and using various data sources, ranging from electronic health records and clinical trial or registry data to administrative, claims, or survey data.

The HAU serves as a resource for CPCE, PolicyLab, and other CHOP investigators using complex data to address research questions. HAU provides services in data extraction and management, statistical programming, biostatistics analysis, and analytics data consultation.
