Specific health risk patterns
Las Marías Municipio, PR: 1 specific risk pattern triggered
Each pattern below combines a specific environmental exposure with a population that is more vulnerable to that exposure. When both are present at meaningful levels in Las Marías Municipio, the pattern triggers. These are the most concrete data points for documenting a significant health need in a Community Health Needs Assessment and for planning where services or community investment would land hardest.
Internally, we call these “Compound Signals.” Each is a versioned, weighted composite scored against the national distribution. The full formula and citations live on the methodology page.
11 dialysis-dependent Medicare beneficiaries (5.17 per 1k).
Extreme heat exposure × Dialysis-dependent population

Heat-Dialysis VulnerabilityLas Marías Municipio: 76/100 (elevated above the 70th-percentile threshold)
Las Marías Municipio: 76/100 (elevated above the 70th-percentile threshold)
Extreme heat × dialysis-dependent Medicare beneficiaries × chronic kidney disease prevalence. Anchored on Taiwan NHIRD findings of 5.3× CKD heat-hospitalization rate, 9× ESRD heat-stroke mortality.
Methodology. Dialysis patients are uniquely heat-vulnerable: missed dialysis sessions during heat-related power loss or transport disruption cause electrolyte cascades within hours. The Taiwan NHIRD analysis (NHIRD = National Health Insurance Research Database) is the strongest population-level evidence we have for the magnitude of the effect.
Threshold. Elevated when score ≥ 70th national percentile across all US counties evaluated for this signal
Peer set. All US counties evaluated for the signal (~3,222, less coverage gaps)
Evidence base
- · Lin Y-K et al. 'Extreme heat and ESRD heat-stroke mortality.' Taiwan NHIRD analysis.
- · Remigio RV et al. 'Association of extreme heat events with hospital admission or mortality among patients with end-stage renal disease.' JAMA Network Open 2019.
Components (3)
Mean of the daily maximum temperature across the meteorological summer (June–August).
NOAA — Applied Climate Information System (ACIS) — RCC-ACIS
Vintage: Multi-year mean (2018–2023 typical) · Refresh: Monthly · Lag: Current year
How it's measured. NOAA ACIS aggregates GHCN-Daily station observations to county-level summer (JJA) daily-max means using inverse-distance weighting. Smooths year-to-year noise; captures the structural heat profile.
Coverage. All 3,222 US counties
5.2 per 1,000 Medicare benes
Rate of Medicare beneficiaries on at-home or in-center dialysis per 1,000 county Medicare beneficiaries.
HHS / ASPR — emPOWER Map — Medicare beneficiary DME data
Vintage: Current month · Refresh: Monthly · Lag: Same month
How it's measured. HHS ASPR derives dialysis-dependent counts from Medicare claims for ESRD-related at-home or in-center service codes, aggregated to county. Reported per 1,000 county Medicare beneficiaries to normalize for size.
Caveat. emPOWER masks counts of 1–10 to the literal value 11 for beneficiary privacy. Per-1k rates derived from masked counts respect the same floor — a small county showing exactly 11 beneficiaries may have anywhere from 1 to 11 actual.
Coverage. All 3,222 US counties (subject to the 1–10 mask)
Percent of adults age 18+ self-reporting chronic kidney disease diagnosis.
CDC — PLACES — Local Data for Better Health
Vintage: PLACES 2022–2023 · Refresh: Monthly · Lag: 1–2 years
How it's measured. PLACES small-area estimation from BRFSS self-report. CKD self-report substantially undercounts true prevalence (most CKD is asymptomatic until late stages).
Coverage. All 3,222 US counties

Where Las Marías Municipio stands
Health risks here sit near national averages
Las Marías Municipio, Puerto Rico sits near the bottom of the national risk distribution across all four major health-risk areas. Pollution exposure, chronic disease rates, doctor access, and social and economic conditions are all better than most U.S. counties. Communities at this end of the spectrum are useful reference points — they help county health planners and CHNA authors understand what a relatively low-need profile looks like across all four dimensions at once.
Methodology: when three or more of the four major health-risk areas (pollution, chronic disease, doctor access, social and economic conditions) score above the 70th national percentile, we call the pattern “multi-pillar convergence.” The scoring approach and citations live on the methodology page.
Risk profile
Las Marías Municipio compared to Puerto Rico and the U.S. average
Four health-risk scores on a 0-100 scale, where 50 is the U.S. average. A higher score means that area is a stronger contributor to community health risk.
Environmental Risk (0) and Provider Gap (8) are at or better than the U.S. average.

Vulnerable Medicare Population
Who needs the grid to stay alive
Medicare beneficiaries in Las Marías Municipio who depend on electricity for dialysis, oxygen, or other powered medical equipment. From the HHS emPOWER program, which CMS publishes monthly so emergency managers know who to find first when the power goes out.

Total Medicare beneficiaries Denominator | 2,128 | — |
Electricity-dependent (any DME) Ventilators, oxygen concentrators, IV pumps, motorized wheelchairs | 135 | 63.4 ▲ +22% vs PR |
Dialysis-dependent ESRD beneficiaries needing in-center or home dialysis | ≤10 | 5.17 ▲ +133% vs PR |
Oxygen-dependent Home oxygen concentrators (outage-vulnerable) | 13 | 6.1 ▲ +5.8% vs PR |
