Social networks evolve over time, driven by the shared activities and affiliations of their members, by similarity of individuals' attributes, and by the closure of short network cycles. We analyzed a dynamic social network comprising 43,553 students, faculty, and staff at a large university, in which interactions between individuals are inferred from time-stamped e-mail headers recorded over one academic year and are matched with affiliations and attributes. We found that network evolution is dominated by a combination of effects arising from network topology itself and the organizational structure in which the network is embedded. In the absence of global perturbations, average network properties appear to approach an equilibrium state, whereas individual properties are unstable.
We examined how well primary-care physicians formulated their clinical referrals when asking for help with patient-related clinical problems using an email-based teleconsultation service. Over 100 family physicians made use of the service. The specialists were medical school faculty members. The service was initiated in May 1996 with 19 specialists and expanded to 34 specialties over the next five years. A total of 1618 patient-related clinical questions were analysed, the outcome for the analysis being whether specialists recommended a clinic consultation. Specialists recommended a clinic consultation in response to 10% of their clinical questions about patients. There was a strong association between how family physicians formulated their clinical questions and whether the specialist recommended a clinic consultation. When the family physicians specified a clinical task (P < 0.001), intervention (P = 0.004) and outcome (P < 0.001) in their questions, specialists were less likely to recommend a clinic consultation. This influence was independent of the amount of clinical information included with the question (P > 0.05). About 5% of the questions that included all three question components resulted in the recommendation for a clinic consultation, compared with nearly 30% of the questions containing none of these components. How family physicians formulate their clinical questions influences whether specialists request a clinic consultation.
