Publication output in telemedicine during the period January 1964 to July 2003

Abstract

The MEDLINE database was used to survey the period January 1964 to July 2003 for the number of publications relating to telemedicine ( n = 5911), as well as their distribution by country ( n = 42). Publications per million inhabitants were then correlated with each country's population density, gross national product, human development index (HDI) and number of PCs per 1000 inhabitants. Telemedicine publications made up 0.05% of all medical publications cited in MEDLINE. American and European countries along with others classified as industrialized produced 97% of all telemedicine publications. In terms of publications per million inhabitants, Norway and Finland took the lead. There were significant correlations between telemedicine publications per capita and HDI ( r = -0.60), number of PCs per 1000 inhabitants ( r = 0.73) and gross national product per capita ( r = 0.69), but not population density ( r = -0.12).
