*Includes only physicians (MD or DO) who practice ongoing primary care for individual patients. This generally excludes paediatricians and those working in public health, hospitals, institutions or emergency care clinics.
†A total census of all “in-scope” physicians was conducted at the outset of service provision. This commenced using the Kentucky Board of Medical Licensure lists and was supplemented by cross reference to listings of primary care physician providers of at least four separate health insurers with a significant market share within the area. The resulting aggregate listings were then checked by telephone calls to each office to confirm that each individual in the listing was truly “in-scope” for targeting by this service. Throughout the duration of visiting, the listing was adjusted to take account of physician movement in and out of the study area as discovered during visits.
