Foraging Theory Applied to Medical Information Searching

Workload and other constraints prevent General Practitioners from accessing medical evidence for clinical decisions. This problem was studied in New Zealand GPs using Optimal Foraging Theory developed in ecology. GPs’ information search strategies were modelled as sequential steps associated with costs and benefits measured from logbooks of actual searches. By consulting the most profitable sources, switching sources when unsuccessful, and double checking, GPs seem close to an optimal trade-off between maximizing search success and information reliability, and minimizing searching time. Subsidised training in information searching and provision of a literature search service are two inferred avenues to access medical evidence.
