Community Health Centers
  -- expanding insights through data analytics

Community Health Centers are an important part of the U.S. health care delivery system. Community Health Centers (CHCs) are organizations that participate in the Health Resources and Services Administration (HRSA), Bureau of Primary Health Care (BPHC) U.S. Public Health Service Act Section 330 programs. See more about CHCs below in this section.

Spring Branch Community Health Center
The following graphic shows the Spring Branch Community Health Center, Texas (Houston area) service area. This type of GIS project has been developed for each/all approximate 1,300 CHCs -- see full list of CHCs in table below. The blue ZIP code areas are those where the health center draws patients cumulative to 75% of total. The green ZIP code areas are those where the health center draws patients cumulative to 75% to 100%. Click graphic for larger view. Expand browser window for best quality view.

CHCs are part of the broader neighborhood and community infrastructure. The ability of a CHC to understand the demographic-economic characteristics, conditions and trends are important to the success of the CHC and the overall area served. The ability of the community and region stakeholders to understand the how CHCs interface with the broader health care delivery infrastructure is equally important. ProximityOne develops and integrates geographic, demographic, economic and business data about, and relating to, CHCs and provides data analytics services to CHC stakeholders. This section provides access to some of these data and tools.

Community Health Center Patterns & Distribution
Using GIS tools ... the following graphic shows the approximately 5,600 HRSA funded regular Community Health Center (CHC) locations. There are a total of more than 10,000 HRSA funded health care delivery system locations. Click graphic for larger view.

More About CHCs
CHCs, also referred to Federally-qualified health centers (FQHCs). have been approved for reimbursement programs under Medicare and Medicaid. To participate as a FQHC, the organization must meet numerous criteria including management, quality of care, scope of services and cost standards. Medicare and Medicaid pay these organizations on a cost-based or cost-derived (usually higher) basis than published fee schedules. FQHCs have the opportunity to apply their reimbursement benefits to managed care enrollees under Medicaid.

CHC GIS Projects
The graphic shown below presents a variation (zoom-in Area 1 blue service/ZIP code areas - per HRSA definition) of the view of this CHC service area shown at the top of this section. This view illustrates how easy it is to add block group (red boundaries) smaller area geography to examine demographic-economic characteristics. ZIP code areas often have a population size too large for the best possible demographic analyses. The pointer illustrates how one block group (48-201-543001-2 with population 3,360) relates to corresponding ZIP code area 77433 with population 60,324.

All nursing homes, hospitals and CHC locations (separate layers shown in legend panel at left) have been click-on and show in the map window. Optionally apply queries on these facilities to view only selected facilities.

Benefits from using the CHC projects ...
  • Use these GIS projects/datasets on your computer without sharing confidential data.
  • Flexibly add any geocoded data or additional/different types of geography and subject matter.
  • Benefit from improved presentation quality to create and publish graphics.
  • Flexibly re-define service areas; simply change the query on a layer to add or remove a ZIP code area.
  • Optionally add census block level geography/demographics.
  • Alternatively define service areas as groups of census tracts.
    .. offering twice the geographic granularity.
    .. more consistent with other clinical and epidemiological small area data.
