Abstract: Abstract The goal of this study was to measure the scientific output of 480 authors—leaders in 12 selected branches of medicine, using the Hirsch index (the h-index) and a newly proposed Scientific Quality Index (SQI). Data were collected from the Scopus database (2008–2017) and scientific output assessments, by the h-index were compared with those by SQI. SQI is calculated by the addition of the percentage of papers cited ≥ 10 times and the mean citation score (excluding self-citations and the citations of all co-authors for both). The following mean values of basic bibliometric parameters were obtained in the whole study group: the citation index: 7250 ± 7817, the total number of papers: 187 ± 104, the total number of cited papers: 175 ± 101, the number of papers cited at least 10 times: 110 ± 75, the percent of papers cited at least 10 times: 51 ± 16, the mean number of citations per paper: 28 ± 21. The mean value of the h-index was 33.2 ± 16.1 and the mean SQI was 78.5 ± 33.4. When ranked, according to the SQI, 279 (58.1%) authors decreased, while 199 (41.5%) improved their ranking position in comparison to the h-index scores. When correlated with the basic bibliometric parameters, SQI was less dependent on both the number of publications and the number of citations in comparison with the h-index. The SQI was strongly influenced by the mean citation score, followed by the percent of papers cited ≥ 10 times. The h-index correlated with the SQI, r = 0.73, p
