title: [Is the rate of medical publication from Israel similar to other countries? A comparative study of three medical specialties].
abstract: Academic careers of individual doctors are commonly evaluated by examining the number and quality of authored publications. Similarly, the extent and quality of medical research may be assessed nationwide by measuring the number of publications originating from the country of interest over time. This in turn, may indicate on the quality of medicine practiced. To evaluate the extent and quality of IsraeLi publications we measured the rate and quality of medical publications originating from Israel for two decades in the fields of urology, cardiology and orthopedics, and compared the data to those of other countries.
  
  
  METHODS
  Leading journals in urology, cardiology, and orthopedics were selected. A Medline search (http://www.ncbi.ntm.nih.gov/sites/entrez] was conducted for all the publications originating in Israel between the years 1990-2009 in the selected journals. Data from Israel was compared to those from Italy, France, Germany, Egypt and Turkey. The change in rate of publications was tested using Linear regression. The quality of publications was calculated by multiplying the number of publications by the relevant impact factor.
  
  
  RESULTS
  While the urology publications rate in Israel increased by 32.7% in the second study decade as compared with the first, the urology publication rates during the same time period from Italy, France, Germany, Egypt and Turkey were 199%, 115%, 184%, 180% and 227% respectively. The regression coefficient for the urology publication rate was 0.51 for Israel, and 0.78, 0.95, 0.78, 0.87 and 0.97 for the other countries, respectively. The regression coefficient for the change in the quality of publications from Israel was 0.31 and 0.81, 0.75, 0.92, 0.73, and 0.92 for the other countries, respectively. In cardiology, the Israeli publication rate increased by 26% during the second study decade, whereas in the other countries the increments were 46%, 35%, 76%, 80% and 309% respectively. The regression coefficient for Israeli pubLication rate was 0.45, and 0.78, 0.54, 0.62, 0.13 and 0.75 for the other countries, respectively. The regression coefficient of the quality of publications in Israel was 0.3 as opposed to 0.47, 0.36, 0.48, 0.01, and 0.78 respectively. The Israeli publications in orthopedics increased by 9.3% during the second decade compared with the first. At the same time, other countries increased the publication rate in orthopedics by 69%, 121%, 173%, 140% and 296% respectively. The regression coefficient for the publication rate in orthopedics was 0.02 for Israel, and 0.62, 0.64, 0.78, 0.34 and 0.71 for the other countries, respectively. The regression coefficient of the quality of publications in Israel was 0.05 as opposed to 0.67, 0.62, 0.75, 0.31, and 0.66 in the other countries, respectively.
  
  
  CONCLUSIONS
  Israel lags behind Italy, France, Germany, Egypt and Turkey with regard to the increase of both the number and the quality of medical publications in urology and orthopedics. While the rate and quality of IsraeLi publications in cardiology surpasses those from Egypt, they lag in the number of publications in this medical field behind those of all the rest of the countries examined. In a world of rapid progress and expansion of medical research, Israel has been stagnant in publications in 3 medical specialties, rendering it inferior to other nations.
