MAS Hospitals — Public Data Sources

What publicly available data exists for the 150 MAS-network hospitals? Research conducted March 2, 2026.

Contents

Our Current Data (hospitals.csv) — baseline coverage audit
Wikipedia (es/en) — 18/150 (12%)
Google Business Listings — 150/150, websites 74%, phones 94%, ratings 100%
Wikidata — 140/150 matched (93%), 123 bed counts, 34 websites
CLUES Registry — ~100% coverage, 68 fields per facility
OpenStreetMap — ~60% match, poor metadata
DGIS / Datos Abiertos — comprehensive ecosystem, 8+ datasets, all free
INEGI ESEP — private hospital census, 2,747 establishments, no CLUES match
IMSS Open Data — delegation-level only, DGIS Sectorial already better
ISSSTE Open Data — 10/11 matched, facility-level Anuario Ch. 15
Pediatric-Specific Sources — promising leads for the pediatric lens we actually need

0. Our Current Data big gaps below ~33%

Baseline audit of hospitals.csv (150 rows, 157 columns). Identity and geography are solid; classification, infrastructure, personnel, and contact have major gaps. This is what we're trying to fill.

Oncologists 32%

Hematologists 31%

Nurse/Patient Ratio 31%

The pattern: ~50 hospitals (the ones that responded to the MAS survey) have rich data across all fields. The remaining ~100 have identity + geography but almost nothing else. This is the enrichment opportunity — external sources can fill hospital level, beds, phone, website, inauguration year, and street address for the full 150.

2. Google Business Listings 150/150 scraped, very rich

All 150 hospitals matched to Google Places records via the Places API. Data saved to google-places.json (150 entries, 13 fields each).

Key finding: 150/150 hospitals matched. Google provides 112 websites (74%), 142 phones (94% — 67 we don't have!), star ratings for all 150, and 115 street view panoramas. Coordinates cross-reference reveals 16 hospitals >1km from our CSV positions, with ICP off by 59km. This is the single richest enrichment source.

Verdict: DONE. All 150 hospitals matched. Most actionable enrichment source overall: 67 new phone numbers, 112 website URLs, street addresses for all 150, ratings as a patient-perception metric, and coordinate cross-referencing that flags 16 potential errors in our CSV positions. Data file: google-places.json

3. Wikidata 93% matched, 1,423 Q-items

Queried Wikidata's SPARQL endpoint for all items classified as hospitals (Q16917 and subclasses) located in Mexico (P17=Q96). Found 1,423 unique Q-items. Used coordinate proximity (haversine distance) + name word-overlap scoring to match against our 150 hospitals.

Key finding: 140 of 150 MAS hospitals matched to Wikidata Q-items (93%): 129 HIGH confidence, 11 MEDIUM. The main value: bed counts (123 hospitals), websites (34), inception dates (15), and stable Q-IDs for linking to the Linked Open Data ecosystem. The 10 unmatched are mostly small private hospitals (DPC, PMA, PMX, etc.) with no Wikidata presence.

PMS	Médica Sur	Q30280169	beds, coords
SLP	Hospital Central Morones Prieto	Q29054809	beds, coords

10 unmatched hospitals

These scored LOW confidence and have no reliable Wikidata match. Mostly small private or specialized facilities with no Wikidata presence: DPC, PMA, PMX, PCC, PDH, PSJ, PCO, PPO, and two others. Many bulk Q-items (Q90XXXXXX series) were mass-imported with coords + beds only.

Practical value: Q-IDs serve as stable identifiers for Linked Open Data. Bed counts from Wikidata (123 hospitals) provide a useful cross-reference against CLUES/Sectorial data. Websites (34) and inception dates (15) add data not available elsewhere. Q-IDs also enable linking to Wikipedia articles, Wikimedia Commons images, and OSM (which carries wikidata= tags).

4. CLUES Registry ~100% coverage

CLUES (Clave Unica de Establecimientos de Salud) is Mexico's official national registry of all health facilities. Maintained by DGIS under the Secretaria de Salud. Every hospital — public, private, or social sector — gets a unique 11-character code.

Key finding: This is the definitive source. The full database is freely downloadable as XLSX with monthly snapshots from 2016–2026. January 2026: 63,477 facilities (6,651 hospitals). All 150 MAS hospitals are matchable via name + coordinates + institution. Download: gobi.salud.gob.mx/Bases_Clues.html

Matching strategy: Combine name fuzzy matching (within same state), coordinate proximity (<2 km), and institution cross-reference. Estimated match rate: 140–150 out of 150. Note: large complexes (like CMN Siglo XXI) have multiple CLUES codes per sub-facility. Download pattern: gobi.salud.gob.mx/historico_clues/ESTABLECIMIENTO_SALUD_YYYYMM.xlsx

5. OpenStreetMap ~60% match, poor metadata

Queried the Overpass API for amenity=hospital and building=hospital across Mexico. Found 3,389 elements tagged as hospitals (1,412 nodes, 1,950 ways, 27 relations), but many are clinics/health centers. True hospital count is likely 800–1,200.

Assessment: OSM covers geographic location and building footprints well, but metadata is very poor. Beds: 3 out of 3,389. Wikidata links: 14. Operator: 21%. Address: 24%. Our CSV is far more complete. Main value: building outlines and contributing data back to OSM.

UMAE Pediatría CMN Siglo XXI — completely absent as distinct entity (only the campus exists)
HIMFG — exists only as misspelled building outline, not tagged as hospital
Name quality inconsistent: misspellings, ALL CAPS, abbreviations, missing names common
Duplicate entries common (same hospital as both node + way)

6. DGIS / Datos Abiertos Comprehensive ecosystem

DGIS (Dirección General de Información en Salud) maintains Mexico's official health data ecosystem. Multiple complementary datasets exist, all keyed by CLUES code — the universal join key across every government health dataset.

Key finding: DGIS provides a comprehensive ecosystem of freely downloadable datasets covering infrastructure, equipment, staffing, patient volumes, quality certification, and more. The CLUES code links everything together. Once we match our 150 hospitals to CLUES codes, we unlock access to dozens of variables across multiple datasets.

Priority datasets (ranked by relevance to MAS)

Results: Recursos en Salud Sectorial 2024 124/150 matched

Downloaded and matched. The Sectorial dataset (229 columns, 23,749 rows) contains facility-level data for all public-sector hospitals. Matched 124 of our 150 hospitals. The 26 unmatched are all private hospitals (SMP) which don't report to government registries, plus HIV (deactivated in CLUES).

Key data now available for 124 hospitals:

Category	Coverage	Network total
Hospital beds	118/124 (95%)	22,936 beds
Operating rooms	117/124 (94%)	950 ORs
Total doctors	120/124 (97%)	30,972

Oncologists	105/124 (85%)	625
Hematologists	110/124 (89%)	316
Linear accelerators	22/124 (18%)	36 units

Bed count range: 747 (Hospital Civil Fray Antonio Alcalde, Guadalajara) down to 0 (some facilities report beds differently). Median: 151 beds.

Results: SINERHIAS / Recursos SSA 2024

Complementary dataset. The SSA/SINERHIAS dataset (147 coded columns, 15,472 rows) covers only Secretaría de Salud and IMSS-Bienestar facilities. Matched 63 of our 150 hospitals. Uses coded field names (C1301, C1401, etc.) — requires the Descriptores lookup file to decode. Data overlaps significantly with Sectorial but at finer granularity for SSA facilities.

Integration strategy — updated: Steps 1-2 are DONE: all 150 hospitals matched to CLUES codes, Sectorial data joined (124 public hospitals). Step 3: Join Egresos for patient volume/diagnosis data. Step 4: INEGI ESEP explored — no CLUES match possible (anonymized). Step 5: IMSS Open Data explored — delegation-level only, DGIS Sectorial already superior. Step 6: ISSSTE Anuario Ch. 15 identified — facility-level XLSX, worth downloading for ~15 federal ISSSTE hospitals. All datasets are free, no API key needed, direct CSV/XLSX downloads.

7. INEGI ESEP (Private Hospital Census) No CLUES — can't match

ESEP = Estadísticas de Salud en Establecimientos Particulares. INEGI's census of ALL private hospitals with beds in Mexico. Covers ~2,747 establishments annually (2024 data). Rich infrastructure data but anonymized — no facility names or CLUES codes in public release.

Critical limitation: ESEP microdata uses anonymized internal folios (scefolio). No CLUES codes, no hospital names, no addresses. Geographic granularity goes to AGEB (census tract) level, but individual facilities cannot be identified. Matching our 25 private hospitals would require fragile fuzzy-matching on state + municipality + bed count — unreliable.

What's in the data (5 CSV files per year)

File	Records	Variables	Contents
RECURSOS	2,747	89	Beds, consultation rooms, ORs, labs, equipment, staff by category
CONEXT	2,747	39	Outpatient consultations (general, specialty, emergency)
HOSPLA	2,747	37	Hospitalizations: admissions, discharges, LOS, births, deaths
PROMED	2,747	41	Diagnostic procedures and treatments
MORBILID	166,795	13	Morbidity records: ICD-10 discharge diagnoses

Verdict: Useful for aggregate private-sector statistics (e.g., "private hospitals in Jalisco have X beds total"), but cannot identify specific hospitals in the public release. Our 25 SMP hospitals are almost certainly in this dataset, but we can't find which row is which. The INEGI Microdata Laboratory offers restricted access with identifiers for approved research projects.

8. IMSS Open Data Delegation-level only

IMSS (Instituto Mexicano del Seguro Social) publishes data through datos.imss.gob.mx (~96 CSV datasets) and the annual Memoria Estadística (15 chapters of XLSX). We have ~40 IMSS hospitals in our network.

Key finding: IMSS open data is aggregated at the OOAD/delegation level (each delegation has 2-8 hospitals), NOT by individual facility. The only exception is the ~25 UMAEs (national specialty hospitals) which have individual data in the Memoria Estadística. For per-hospital infrastructure data on our IMSS hospitals, DGIS Recursos Sectorial (which we already have) remains the best source.

What exists and its granularity

Source	Granularity	Format	Useful?
datos.imss.gob.mx "Información en Salud"	By delegation	CSV	Marginal
Memoria Estadística Ch. IV (Services)	By delegation + 25 UMAEs by name	XLSX	For UMAEs only

Verdict: Low additional value for our project. DGIS Recursos Sectorial already provides CLUES-level data for all our IMSS hospitals (beds, equipment, staffing). The IMSS Memoria adds UMAE-specific service volumes (consultations, discharges, surgeries per named facility) that could supplement Sectorial for the ~10 UMAEs in our network. The Cognos cube system is worth investigating interactively — it may allow facility-level queries.

9. ISSSTE Open Data 10/11 matched, facility-level

ISSSTE publishes the Anuario Estadístico annually (25 years: 2000-2024), plus 45 datasets on datos.gob.mx. Chapter 15 is the prize: facility-level XLSX data on infrastructure, equipment, ICU, and staffing for every ISSSTE unit.

Key finding: Downloaded and matched Ch. 15 data. 10 of 11 federal ISSSTE hospitals matched via CLUES codes in the spreadsheets. Extracted beds, ICU, operating rooms, equipment (MRI, CT, ventilators), and staffing by specialty (including oncologists). SGF (Hospital Gómez Farías, Jalisco) not found in 2024 data — possibly transferred or closed. State ISSSTEs (TCA, TCH, TPB) are separate institutions not in the federal Anuario.

State-level ISSSTE equivalents

State ISSSTEs (ISSSTECALI, ISSTECH, ISSSTEP) are separate institutions from federal ISSSTE — their hospitals are NOT in the ISSSTE Anuario.

HCODE	Institution	Open Data?
TCA	ISSSTECALI (Baja California)	None found
TCH	ISSTECH (Chiapas)	None found
TPB	ISSSTEP (Puebla)	Puebla open data — units directory

Verdict: DONE. 10 of 11 federal ISSSTE hospitals matched and extracted. The Anuario Ch. 15 adds 100+ fields per hospital including detailed staffing by specialty (oncologists, anesthesiologists, geriatrics), equipment inventory (MRI, CT, ventilators, infusion pumps), ICU/NICU capacity, and consulting rooms. CLUES codes are embedded in the spreadsheets — no fuzzy matching needed.

Integration strategy — updated: Steps 1-2 are DONE: all 150 hospitals matched to CLUES codes, Sectorial data joined (124 public hospitals). Step 3: ISSSTE Anuario Ch. 15 DONE — 10/11 federal ISSSTE hospitals matched with 100+ fields each. Step 4: Wikidata DONE — 140/150 hospitals matched with bed counts (123), websites (34), inception dates (15). Step 5: INEGI ESEP explored — not actionable (anonymized). Step 6: IMSS Open Data explored — marginal (delegation-level). Next: Join Egresos for patient volume/diagnosis data. All datasets are free, no API key needed, direct CSV/XLSX downloads.

10. Pediatric-Specific Sources Not yet extracted — promising leads

The fundamental limitation of sources 4-9 (CLUES, DGIS Sectorial, ISSSTE Anuario, Wikidata) is that they measure the whole hospital, while MAS cares about the pediatric hematology/oncology unit within each hospital. A hospital with 500 total beds might have 15 PHO beds. A hospital with 12 total oncologists might have 3 pediatric oncologists. The enrichment data gives useful context (hospital size, general resources) but cannot fill gaps in our survey's pediatric-specific columns.

Key discovery: DGIS Recursos en Salud Sectorial (already downloaded, 229 columns) contains pediatric beds, oncology beds, hematology beds, chemotherapy beds, BMT beds, pediatricians — as separate columns, not just aggregates. We only extracted the totals. Going back to extract these pediatric-specific columns would be the highest-value next step.

DGIS Sectorial: untapped pediatric columns

Column	Field	Units with data
106	Camas de Pediatría	1,165
103	Camas de Oncología	126
96	Camas de Hematología	98
120	Camas en quimioterapia	195
122	Camas en transplante de médula ósea	16
77	Consultorios de Pediatría	1,282
74	Consultorios de Oncología	252
142	Pediatras (count)	1,321
37	Área de quimioterapia (yes/no)	261
36	Área de radioterapia	50
128	Aceleradores lineales	46

95 hospitals have BOTH pediatric beds AND oncology beds — a strong proxy for pediatric oncology capability.

Other promising sources (not yet extracted)

Source	What it offers	Format	Effort
CENSIA UMA Directory	64 hospitals accredited for pediatric cancer treatment. Accreditation type: hematologic malignancies, solid tumors, CNS tumors, BMT.	PDF	Manual / OCR
SAEH Egresos Hospitalarios	Hospital discharge microdata with CLUES + patient age + ICD-10 diagnosis. Filter age<18 + C00-C97 = pediatric cancer caseload per hospital.	CSV	Download + filter
RCNA 2019 Report	Pediatric cancer registry: per-hospital case counts from 52 reporting UMAs. 100% pediatric-specific.	PDF	Manual / OCR
Consejo de Salubridad General	86 certified hospitals (quality standards). Not pediatric-specific but useful as quality flag.	PDF	Manual

Recommended next steps: (1) Re-extract DGIS Sectorial with pediatric-specific columns (already downloaded, just need to re-run extraction). (2) Download SAEH Egresos and compute pediatric cancer caseload per CLUES — this would be the strongest signal of actual PHO activity per hospital. (3) The CENSIA UMA directory and RCNA reports are PDFs requiring manual extraction.
