Traditionally corridor consultations happen when colleagues bump into each other or, as working practices have changed, specialists respond to a phone call. At their heart they are ad hoc and impromptu. Holistic joint consultations are most effective when they happen early in the patients journey. In many instances, this is the moment the patient first presents in a GPs surgery. A specialist service needs to organise its specialist’s time effectively to satisfy this need and provide a reactive, on-demand service. An advice and guidance system should work so that multiple specialists can give advice whilst doing other non-patient facing activities. In theory (cue scoffing and general derision), a consultant has 10 hours available each week for supporting professional activities (SPA’s). This means when a GP is looking for advice, the system can automatically contact multiple specialists using their mobiles to see if they are available to give advice. This flexibility lowers the threshold for specialist availability and increases the chance that a specialist will be available to give advice.
