%X The attitudes of general practitioners (GP) play an influential role in their decision making about patient treatment and care. Considering the GP-patient encounter as a complex system, the interactions between the GP and their personal network of peers give rise to ¡°aggregate complexity,¡± which in turn influences the GP¡¯s decisions about patient treatment. This study models aggregate complexity and its influence in decision making in primary care through the use of social network metrics. Professional network and attitudinal data on decision making responsibility from 107 rural GPs were analysed. Social network measures of ¡°density¡± and ¡°inclusiveness¡± were used for computing the ¡°interrelatedness¡± of components within such a ¡°complex system.¡± The ¡°number of components¡± and ¡°degree of interrelatedness¡± were used to determine the complexity profiles, which was then used to associate with responsibility in decision making for each GP. GPs in simple profiles (i.e., with low components and interactions) in contrast to those in nonsimple profiles, indicate a higher responsibility for the decisions they make in medical care. This study suggests that social networks-based complexity profiles are useful for understanding decision making in primary care as it accounts for the role of influence through the professional networks of GPs. 1. Introduction The attitudes of health professionals such as general practitioners (GPs) play an influential role in their delivery of medical care, such as communication and decision making in patient care. A number of other studies have focused on examining the GP¡¯s delivery of medical care from various perspectives: quality of the consultation [1]; psychological and medical functions [2]; measuring informed decision making through evaluating patient-GP encounters [3]; influence through professional networks [4, 5]. More recently, there is evidence showing how medical care delivery can be conceptually analysed using principles of complexity thinking, where the GP-patient consultation is deemed to be a complex adaptive system [6]. According to Plsek and Wilson [7], ¡°complexity thinking suggests that relationships between parts (of a system) are more important than the parts themselves, and that minimum specifications yield more creativity than detailed plans.¡± It is useful to consider the meaning of systems within which complexity is situated and derived and the type of systems that is referred to in this paper. Broadly speaking, ¡°systems¡± consist of multiple parts (or components) that are connected and interrelated in one or
