Population Health Program




The HSX Population Health Program provides access to a large, robust healthcare data set of encounter-level and clinical information on groups of individuals from multiple sources.

Participants interested in taking advantage of HSX population-health/public-health services have access to data elements for large sets of patients.  These records include demographics, encounter data, diagnosis, allergy, insurance, medication and other clinically relevant variables (see below).  HSX has recent and longitudinal medical information on more than seven million people in its Greater Philadelphia/Delaware Valley service region, and it accumulates and expands this database daily.


Organizations conducting population health or public health initiatives can use HSX data to support:

  • Disease or Health Risk Monitoring
  • Outbreak Investigations
  • Performance Management
  • Population Health Assessments
  • Community Health Needs Assessment (CHNA)
  • Population Health Management
  • Prevention Services
  • Program Evaluation
  • Public Health Reporting

Access to HSX Data

Participants interested in accessing HSX data can do so by requesting:

  • Extraction of Historical Data — encounter or individual data for requested elements
  • Standard and Custom Reports — scope defined by request, available in various delivery options
  • Participant-Subscribed Reports — custom report run daily, weekly, monthly, or quarterly
  • Dashboards (live data) — visual representation of data in real time, with credentialed web access

Data may be provided in an identifiable or de-identified manner depending upon the scope of the population health endeavor.

Current Initiatives

eCQM Reporting

Hospitals can submit electronic clinical quality measures (eCQMs) via HSX to the Pennsylvania Department of Human Services (DHS) eCQM registry available on the Public Health Gateway (PHG).

See the HSX eCQM Reporting FAQ

Utilization Subscription Reporting

These monthly subscription-utilization reports  support quality programs such as the Hospital Readmissions Reduction Program (HRRP).  See an example of a Scope of Work agreement for this service.

Executive Utilization Dashboard

The HSX Population Health Program provides this utilization snapshot to the leadership of HSX-participating health systems or hospitals.  The dashboard represents aggregate data on acute-care and emergency-department utilization for the recipient's facilities compared to the overall HSX community.

Opioid Reporting

This service provides data to the City of Philadelphia Department of Public Health Opioid Surveillance Task Force on opioid use disorders or overdoses for Philadelphia residents based on the Admission Discharge Transfer (ADT) messages from HSX-contributing emergency departments and acute care hospitals.

The Mission of the program is to improve population health and enhance quality of care by leveraging HSX assets and community data.

The Vision of the program is to expand as the trusted source of population health data for Greater Philadelphia and the neighboring regions.

Montgomery Co. Behavioral Health ED Visits Analysis
Data collection and analysis of the incidence and nature of visits to Montgomery County emergency departments (EDs) by patients for behavioral health needs, performed for the Montgomery County Hospital Partnership. The Partnership has provided Montgomery County hospitals and other stakeholders an opportunity to explore how to effectively and safely address patients’ behavioral health needs, including referring patients to timely and appropriate treatment, with the aim of ultimately reducing ED use for behavioral health needs.  By increasing understanding of the demographics and ED utilization patterns of patients with behavioral health needs in the county, the analysis helped to inform the Partnership’s intervention strategies. HSX provided data to the Health Care Improvement Foundation, which analyzed the data on behalf of the Partnership. HealthSpark Foundation funded this project.

Capstone Project Using HSX Data for Community Health Needs Assessments (CHNA)
Jefferson School of Population Health Capstone project that used HSX data to evaluate and characterize health outcomes and determinants, reflect community perspectives, and identify assets of the community to support a Community Health Needs Assessment (CHNA).

See the poster. 

See the paper.


Examples of Population Health Uses of HSX Data

  • With the aim of identifying barriers to accessing behavioral healthcare in communities and gaining a better understanding of emergency department utilization, a client of HSX population health services requests an Extraction of Historical Data to conduct retrospective data analysis to increase the quality of care for this population.
  • A primary care practice is interested in better understanding its patient population related to birth outcomes, specifically
    birthweights and post-partum visits over a specified period of time. A Participant-Subscribed Report would be generated
    on a predetermined cadence.

    See a detailed description of uses available of the Population Health Program by HSX participants and by public health authorities.
