This study proposes an integrative review of the literature based on articles and publications on the use of the Primary Care Assessment Tool (PCAT) as a tool for evaluating these services, discussing the results found in Brazil and in other countries of the world, from the initial matrix conceived by Professor Barbara Starfield's team and proposing updates for the Brazilian version. We identified 124 studies, of which 42 were selected after full reading and according to the established inclusion criteria. Of this subtotal, 17 (40.5%) were Brazilian studies. There is a need to update items of each tool's attribute, in particular "access - first contact", including new forms of doctor-patient communication such as: email, mobile application messages, use of videoconference software for communication and even use of telemedicine, among others. PCAT's use, application and calculation of scores is simple, which makes it useful and suitable for use in the local management of services, especially in its short version.
