  The shared positive outcome ratio (SPOR) provides a weight for relationships based on the relative success of a provider pair. The SPOR answers this question: How many more positives outcomes do these providers attain when they collaborate vs when they collaborate with other providers? In this example, 30 patient encounters are shown. Some patients report a positive outcome (“highly likely to recommend Northwestern Medicine to others”, red), whereas others report a negative outcome (“not highly likely to recommend,” black). Provider 1 (P1) interacts with 20 of these patients and Provider 2 (P2) interacts with an overlapping 20 patients. Providers 1 and 2 share 10 patient encounters with 9 of 10 reporting a positive outcome. If the rate of satisfaction was the same inside the overlap as it is outside of the overlap, the SPOR would be 1, which is the expected value. In this example, however, both providers have greater success when working together (ie, inside the overlap) and the SPOR value is greater than 1. This metric was calculated for each pair of providers in the network.Show Less

  Shared positive outcome ratio (SPOR) distribution densities. The effect of 5 shared patient threshold values on the density of the SPOR value distributions in the collaboration network is shown. The SPOR values are given in log₂ form. The distribution narrows as the threshold is increased, revealing the trade off between the relative stability of an approximately normal distribution and the inclusion of potentially interesting relationships based on fewer shared encounters.
