Abstract: Method and apparatus for the collection and management of healthcare practitioner profile information prior to inclusion in a hospital directory of affiliated practitioners or insurance provider directory of participating practitioners. Healthcare practitioners (e.g., physicians) enter and communicate changes to their profile data to a central database to increase their compliance and decrease the frequency of providing updated or incomplete information in a hospital or insurance provider directory. The profile data can be credentialed according to rules specific to each hospital or insurance provider, prior to inclusion in the directory. The directory may further provide online booking of available appointment times for affiliated physicians from multiple practice groups. The online booking process can simultaneously be available on multiple websites of a hospital, insurance provider, physician practice group and/or centralized provider (aggregator).
