    HCI recognises the “sandwich” of users/interactive systems/tasks - ideally achieving effectiveness, efficiency and satisfaction for the user - hence user centred design and other key methodologies of HCI. For medical apps this is not sufficient, as patient outcomes are more important than usability. We aim to stimulate discussion on the need for a new approach, we tentatively call “pizza HCI,” which emphasises the more rounded form of HCI needed to respect the patient: patient/clinician/system/clinical task/patient. Core user-centred design methods, such as think aloud, need extending into pizza HCI by greater emphasis on stakeholders than on users in isolation.
