Popis: The Hirsch Index (h-index) is often used to assess research impact, and on average a social science senior lecturer will have an h-index of 2.29, yet its validity within the context of UK General Surgery (GS) is unknown. The aim of this study was to calculate the h-indices of a cohort of GS consultants in a UK Deanery to assess its relative validity.Individual h-indices and total publication (TP) counts were obtained for GS consultants via the Scopus and Web of Science (WoS) Internet search engines. Assessment of construct validity and reliability of these 2 measures of the h-index was undertaken.All hospitals in a single UK National Health Service Deanery were included (14 general hospitals).All 136 GS consultants from the Deanery were included.Median h-index (Scopus) was 5 (0-52) and TP 15 (0-369), and strong correlation was found between h-index and TP (ρ = 0.932, p0.001), with the intraclass correlation between Scopus and WoS h-index also significant (intraclass correlation coefficient = 0.973 [95% CI: 0.962-0.981], p0.001). Academic GS consultants had higher h-indices than nonacademic University Hospital and District General Hospital consultants (Scopus 12 vs 7 vs 4 [p0.001] and WoS 10.5 vs 7 vs 4 [p0.001]). h-Index was2.29 in 57.4% of consultants. No subspecialty differences were apparent in median h-indices (p = 0.792) and TP (p = 0.903).h-Index is a valid GS research productivity metric with over half of consultants performing at levels equivalent to social science Senior Lecturers.
