Therapeutic Geographic Coverage Gap
Compare person-level therapeutic coverage with area-level geographic coverage.
Description
Treatment reach has two distinct denominators: eligible people and geographic areas.
Treatment reach has two distinct denominators: eligible people and geographic areas. A region can report broad geographic delivery while many eligible people remain untreated.
The tool returns therapeuticCoveragePercent (therapeutic coverage percent); geographicCoveragePercent (geographic coverage percent); coverageGapPoints (coverage gap points). Input measurements and model parameters are supplied by the caller; the tool computes the stated summary rather than acquiring those measurements.
When to use Therapeutic Geographic Coverage Gap
Use Therapeutic Geographic Coverage Gap when you already have therapeuticCoveredPeople, eligiblePeople, coveredAreas, totalAreas and want therapeuticCoveragePercent, geographicCoveragePercent, coverageGapPoints. This is useful for checking a supplied calculation, documenting a measurement convention, or comparing observations prepared on the same basis.
How to use Therapeutic Geographic Coverage Gap and understand its results
- Enter therapeuticCoveredPeople, eligiblePeople, coveredAreas, totalAreas using the field table below. Match the units, ordering and data boundaries described in the calculation.
- Run the tool after checking the stated bounds and matching paired observations or categories. A malformed request gives a tool error rather than a usable measurement.
- Read therapeuticCoveragePercent, geographicCoveragePercent, coverageGapPoints. Use the calculation and interpretation below to distinguish amounts, ratios, signs and decision flags where applicable.
- Review the supplied parameters and assumptions before using the result in a report or comparing it with another observation.
| Input field | Meaning | Value type and bounds | Requirement |
|---|---|---|---|
| therapeuticCoveredPeople | Therapeutic covered people | integer | Required |
| eligiblePeople | Eligible people | integer | Required |
| coveredAreas | Covered areas | integer | Required |
| totalAreas | Total areas | integer | Required |
Validate integer counts and positive denominators, then return both percentages and their signed percentage-point difference.
therapeutic coverage = 100 × treated/eligible; geographic coverage = 100 × coveredAreas/totalAreas; gap = geographic − therapeutic The symbols refer to the supplied quantities or generated values described above; unit conversions and comparison boundaries follow the stated implementation.

}Limitations and assumptions
A gap measures two reported coverage dimensions; it does not identify the cause or independently verify delivery records.
Numerical inputs must be finite. The tool checks its declared input shape and calculation constraints; those checks do not verify the quality, calibration or representativeness of the supplied observations.
