[Shift- and Nightwork - a scientometric analysis]. / Schicht- und Nachtarbeit - eine szientometrische Analyse.

ABSTRACT

Economic restructuring processes in Germany require changes within all social and health care systems regarding night shiftwork. The aim of this paper was to analyse research results referring to shift- and nightwork using scientometric methods. A total of 3092 items could be detected. A constant increase in the number of publications per year since 1977, especially since 1990' was obvious. One third of the research results, a total of 884 articles could be assigned to the USA. Great Britain could be identified with 365 articles and France with 244 published articles. Sleep, Ergonomics and Chronobiology International are the most prolific journals. The Swedish scientist Torbjörn Akerstedt is to this date the most acclaimed researcher referring to his issue. He has written 105 articles about shift- and nightwork. He is not only a most efficient author, but also has the highest h-index [30]. Self-citations and multiple co-authorships distort parameters like impact factor and h-index enormously and should be regarded from a critical point of view.
