What Is a Good H-Index in Medicine? 2026 Benchmarks for Medical Researchers

Medicine is a high-citation discipline: large research communities and citation-rich review articles produce H-Index values above most other fields. But values depend strongly on how long a researcher has been publishing. This guide shows measured H-Index percentiles for Medicine & Biology by academic age, from a seeded OpenAlex author sample (October 2026).

H-Index benchmarks for medical researchers 2026
// Key Findings
  • Medicine & Biology median H-Index: h=4 (measured, n=9,286 authors)
  • Top 10% of medical researchers: h≥17; top 5%: h≥24
  • Academic age 21+ years: median h=5, top 10% h≥24 (n=4,407)
  • El Emam et al. (2012), Scopus-based medical informatics percentiles: p50≈4.9, p75≈12.6, p90≈22.9
  • H-Index used as supporting evidence in O-1A and EB-1A visa petitions

Measured percentiles from a seeded random sample of 9,286 OpenAlex author records in Medicine & Biology (snapshot 2026-10; doi:10.5281/zenodo.23744421). OpenAlex-based; Google Scholar values are typically higher. Academic age (years since first publication) approximates, but is not, academic rank.

Direct comparison study: El Emam et al. (2012)

For medical informatics researchers publishing in the two top journals of that specialty (Scopus data, 2006–2011), El Emam et al. report H-Index percentiles of p50 ≈ 4.9, p75 ≈ 12.6, p90 ≈ 22.9 (Table 3, doi:10.2196/jmir.2177). Different database, population and time window than our OpenAlex sample — values are close at the median but higher at the top end.

// Review Articles and H-Index Inflation in Medicine

Review Articles and H-Index Inflation

A systematic review or clinical guideline in Medicine can accumulate thousands of citations. Researchers who write review articles tend to reach higher H-Index values than colleagues publishing only original research.

Hiring committees at research-focused institutions are aware of this and often examine the composition of an applicant's citation record alongside the H-Index.

H-Index Differences by Medical Specialty

Not all medical specialties produce the same citation volumes. Basic science fields tend to generate more citations per paper than clinical specialties.

Specialty / Area Citation Volume Relative H-Index Threshold
Molecular Biology / GeneticsVery HighAbove median
OncologyVery HighAbove median
CardiologyHighAt or above median
Neurology / NeuroscienceHighAt or above median
General Internal MedicineModerateNear median
SurgeryModerateNear or below median
PsychiatryModerateNear median
// H-Index in O-1A and EB-1A Visa Applications

H-Index in O-1A and EB-1A Visa Petitions

Medical researchers applying for O-1A or EB-1A visas increasingly include bibliometric data as supporting evidence of outstanding achievement.

Important: No official H-Index threshold exists

USCIS does not publish an H-Index threshold. The H-Index is used as contextual evidence. Field-normalised percentile data showing top 10% or top 5% standing is typically more persuasive than the raw number.

Always work with an immigration attorney for visa petitions.

The benchmarks on this page and in our H-Index Benchmarks 2026 report provide the field-normalised percentile context that these applications require.

// Frequently Asked Questions
What is a good H-Index for a medical researcher?
In our measured OpenAlex sample, the median H-Index in Medicine & Biology is h=4 (n=9,286). By academic age: median h=2 at 0–5 years, h=4 at 6–10, h=5 at 11–20 and h=5 at 21+ years. Reaching the top 10% requires h≥9 at 6–10 years, h≥14 at 11–20 and h≥24 at 21+ years. OpenAlex-based; Google Scholar values are typically higher.
What H-Index is needed for a medical school faculty position?
There is no official cutoff. For context: in our measured sample, researchers at 6–10 academic years have a median of h=4 and reach the top 25% at h≥6 — many Assistant Professor candidates fall in this band. Committees usually weigh trajectory and citation composition more than the raw value.
How does H-Index differ between clinical and basic science in medicine?
Basic science researchers typically accumulate citations faster than clinical researchers. Oncology/cardiology higher than surgical specialties.
Can H-Index help with O-1A or EB-1A visa petitions?
Yes — bibliometric data is commonly included as supporting evidence. However, USCIS has no published H-Index threshold. Field-normalised percentile data showing top 10% or top 5% standing is typically more useful than the raw H-Index value alone. Always work with an immigration attorney.
Does writing review articles inflate H-Index in medicine?
Yes. Review articles in Medicine accumulate citations much faster than original research papers, so researchers who write reviews tend to reach higher H-Index values than colleagues at the same academic age.
