Using the Nominal Group Technique: how to analyse across multiple groups

This paper aims to demonstrate the versatility and application of nominal group technique as a method for generating priority information. Nominal group technique was used in the context of four focus groups involving clinical experts from the emergency department (ED) and obstetric and midwifery areas of a busy regional hospital to assess the triage and management of pregnant women in the ED. The data generated were used to create a priority list of discussion triggers for the subsequent Participatory Action Research Group. This technique proved to be a productive and efficient data collection method which produced information in a hierarchy of perceived importance and identified real world problems. This information was vital in initiating the participatory action research project and is recommended as an effective and reliable data collection method, especially when undertaking research with clinical experts. © 2012 Blackwell Publishing Asia Pty Ltd.

Qualitative methods are increasingly recognized as valuable, yet practitioners face difficult decisions in their choice of method and the process of analysis. The nominal group technique combines quantitative and qualitative data collection in a group setting, and avoids problems of group dynamics associated with other group methods such as brainstorming, Delphi and focus groups. Idea generation and problem solving are combined in a structured group process, which encourages and enhances the participation of group members. The stages involved in conducting a nominal group are described, and practical problems of its use in a health care setting are discussed with reference to a study of the priorities of care of diabetic patients, carers and health professionals. Some potential applications of the technique in audit and exploratory research are also outlined.
