CAHRU/LIH improvement science and research methods seminar: Mixed methods

QIlogoThe first of this year’s series of CaHRU/LIH (Community and Health Research Unit/Lincoln Institute for Health) improvement science and research methods seminars was given by Prof Siriwardena on mixed methods on 16 February 2016. Improvement and implementation science benefits from the use of mixed research designs which combine quantitative and qualitative methods to show not only what happened but also why and how this might have occurred. Mixed methods approaches are a subset of multiple methods which involve more than one type of qualitative or quantitative method.

ascqilogoThe seminar covered principles such as definitions, theoretical approaches (such as pragmatism and transformation), basic and advanced (including case study) designs and approaches to data integration and transformation. This was then applied to examples of mixed methods designs used by CaHRU in a previous programme of research: the Ambulance Services Cardiovascular Quality Initiative (ASCQI). ASCQI was a national project, led by CaHRU and East Midlands Ambulance Service NHS Trust, designed to improve care for people presenting to ambulance services with heart attack or stroke using a large-scale quality improvement collaborative (QIC), evaluated using a multiple case-study design.

NWASami170112ASCQI involved gathering quantitative and qualitative data to describe what effect the QIC had, and how improvements, if they did occur, were brought about. Integration of data was carried out using techniques such annotated control charts showing time series data together with what was implemented, pattern matching comparing what services did and whether improvements occurred (doi:  10.1186/1748-5908-9-17), and comparison of quantitative and qualitative data from an online questionnaire (doi: 10.1111/jep.12438). Attendees were finally asked to consider a mixed methods question and think about research designs which they might use to answer it.

Thank you to all those staff and students who attended. Details of future seminars will be posted on the CaHRU and the LIH sites shortly.
