Clinical Neuroscience Research in Saudi Arabia: A Comparative Evaluation of Performance at Country and Worldwide Levels Based on the Relative Specialization Index.

This review is an appraisal of the performance of clinical neuroscience research in Saudi Arabia based on the measurement of the Relative Specialization Index (RSI). The latter is an established quantitative performance indicator that determines whether a country has a relatively higher or lower share in world publications in a specialty than its overall part in the world total publications. The study aimed to assess the trends in the specialty's RSI, comparing it to other medical specialties in Saudi Arabia and to that of the top 50 countries worldwide in clinical neuroscience. SCImago Journal and Country Rank were used to determine the total articles and total citations for 46 medical specialties in Saudi Arabia and clinical neuroscience in the worldwide top 50 countries during 1996‑ 2023. The RSI was calculated for each medical specialty and each country. A positive or negative RSI implied that the specialty's share in the country's total documents or total citations was higher or lower than the average for the specialty worldwide. A steady increase in Saudi Arabia's total articles and total citations in clinical neuroscience was observed over the last 28 years. The RSI values, however, remained negative throughout except for limited periods (2003-2006 for total articles) and (1996 and 1998 for total citations). Compared to other medical specialties in Saudi Arabia, the specialization performance for clinical neuroscience was within the mid-range in total articles (ranking 30 out of 46 specialties) and the low range in total citations (ranking 39 out of 46 specialties). Saudi Arabia's worldwide ranking in clinical neuroscience based on total citations was 39; however, the country's ranking dropped to 45 when the RSI values were applied. Furthermore, clinical neuroscience was considered to have had a strong relative contribution (RSI ≥ 0.1) to the total articles in five countries (Italy, Austria, Germany, Japan, and Canada) and total citations in six countries (Luxembourg, Austria, Germany, Canada, Italy, and Finland). In conclusion, despite an increase in Saudi Arabia's total articles and total citations in clinical neuroscience over the years, the specialty's relative share of the total productivity in the country remains lower than the overall for the specialty worldwide. The performance of the specialty was within the mid-to-low range compared to the other 45 medical specialties in Saudi Arabia. In addition, the country's worldwide ranking based on total citations in the specialty dropped when the RSI was used. Clinical neuroscience researchers in Saudi Arabia are encouraged to improve the quality and quantity of their research productivity to be one of the leading medical specialties in Saudi Arabia.
