A survey was sent to all hospital-based IPs in Kentucky in November 2010. Density and component analyses were used to evaluate network cohesion, and centrality statistics and key player algorithms were used to identify IPs important to the network.
A total of 75 (58%) IPs completed the survey. The network density was 1.8%. Three components were identified. The median (range) centrality measures were as follows: in-degree, 2 (0-11); out-degree, 0.5 (0-5); betweenness, 0 (0-567); and eigenvector 0.02 (0-0.45). Three key players were identified.
Low network statistics indicate that the knowledge-sharing network of hospital-based IPs might not be adequate for efficient knowledge-sharing. Interventions to increase the density of the network and reduce the number of components are needed.
