Two major resources on Group Appointments relate to various medical settings (i.e., not primary care alone). The 'Bible' of Group Appointments is Dr. Edward Noffsinger's 500-page book Running Group Visits in Your Practice (2009). He describes two main types of GAs -not limited to the primary care setting. A second foundational source for Canadians in particular, is The Group Medical Appointment Manual (First Edition 2007) published by the Northern Health Authority in British Columbia (developed after a visit by Dr. Noffsinger).
