Physician panel

Who answers your studies.

A study is worth what its sample is worth. We publish how we recruit, how we verify and what we control during fieldwork, because that is the only way you can judge a figure before using it in a decision.

Verification

No one joins the panel without a licence

  1. Step 01

    Professional identity

    Professional and specialty licences validated against the public registry before first participation.

  2. Step 02

    Practice profile

    Institution, level of care, region, consultation volume and patient profile treated, declared and cross-checked.

  3. Step 03

    Per-study screening

    Each project applies its own eligibility criteria. Panel membership does not guarantee entry into the sample.

  4. Step 04

    Re-verification

    Profiles updated every 12 months. Anyone who changed institution or left clinical practice drops out of the active quotas.

Field control

What is audited in every fieldwork round

Controls are not an appendix to the report: they are the reason a figure can hold up in a committee. All of them are documented in the methodological memo accompanying every delivery.

  • Audit of 100% of cases

    Full review of every questionnaire, not a control sub-sample.

  • Duration control

    Cases outside the expected range are reviewed one by one and discarded where warranted.

  • Consistency items

    Mirror items within the instrument to detect automatic or contradictory responding.

  • Quota traceability

    Progress by specialty, institution and region visible during fieldwork, not only at close.

  • Declared effective base

    Every table reports its real n and margin of error; cross-tabs under 30 cases are flagged as indicative.

  • Anonymisation

    Microdata are delivered without identifiers, in line with Mexican data protection law and the signed consent.

Coverage

Specialties and institutions

Frequent specialties

Internal medicine · Cardiology · Endocrinology · Medical oncology · Neurology · Rheumatology · Pulmonology · Nephrology · Gastroenterology · Infectious diseases · Psychiatry · Dermatology · Gynaecology · Paediatrics · Family medicine

Sectors

IMSS · ISSSTE · IMSS-Bienestar · State health services · National institutes · Private hospitals · Independent private practice. Samples are stratified by sector because prescribing habit changes with the formulary available.

Geography

National coverage concentrated in the Valley of Mexico, Guadalajara, Monterrey, Puebla, Querétaro and Mérida. LATAM projects through a partner network under the same verification protocol.

If your indication requires a specialty not on the list, we recruit to order. In very small universes we say so before contracting and adjust the design instead of forcing the quota.

Does your sample exist?

Tell us the specialty, the sector and the eligibility criteria. We confirm sample feasibility before you invest in a design.
