[DNVF-Memorandum III - Methods For Health Services Research, Part 4 - Concept and Methods For Organizational Health Services Research. Chapter 1 - Definition and Concept of Organizational Health Services Research].

Organizational health services research is still a relatively young field of research in Germany which is of increasing interest. The German Network Health Services Research e.V. (DNVF e.V.) published in 2009 - supported by expert associations and individual members of the DNVF - a guide on "Methods for organizational health services research" of the Memorandum III, part 1[1]. Originating from this publication and facilitated by the increasing relevance of the field, a necessity to refine the conceptual and methodological basis became evident. The update and extension of the publication from 2009 consists of three chapters: (1) Definition and concept of organizational health services research, (2) Methodological approaches in organizational health services research: indicators, data sources, data collection and data analysis, (3) Methodological approaches for the design, evaluation and implementation of complex interventions in health care organizations. The aim of the first chapter is to present the theoretical framing and the definition of terms and tasks within organizational health services research.
