Synthesising diverse evidence: the use of primary qualitative data analysis methods and logic models in public health reviews

By S. Baxter, A. Killoran, M. Kelly and E. Goyder


Objectives: \ud The nature of public health evidence presents challenges for conventional systematic review processes, with increasing recognition of the need to include a broader range of work including observational studies and qualitative research, yet with methods to combine diverse sources remaining underdeveloped. The objective of this paper is to report the application of a new approach for review of evidence in the public health sphere. The method enables a diverse range of evidence types to be synthesised in order to examine potential relationships between a public health environment and outcomes.\ud \ud Study design: \ud The study draws on previous work by the National Institute for Health and Clinical Excellence on conceptual frameworks. It applied and further extended this work to the synthesis of evidence relating to one particular public health area, the enhancing of employee mental wellbeing in the workplace.\ud \ud Methods: \ud The approach utilised thematic analysis techniques from primary research together with conceptual modelling to explore potential relationships between factors and outcomes. \ud \ud Results: \ud The method enabled a logic framework to be built from a diverse document set that illustrates how elements and associations between elements may impact on the wellbeing of employees. \ud \ud Conclusions:\ud Whilst recognising potential criticisms of the approach, it is suggested that logic models can be a useful way of examining the complexity of relationships between factors and outcomes in public health, and of highlighting potential areas for interventions and further research. The use of techniques from primary qualitative research may also be helpful in synthesising diverse document types.\u
