FHIR R4 Resource: Definition and Structure of the Slot Resource

Details

This document comprehensively explains the structure and attributes of the 'Slot' resource within the HL7 FHIR R4 standard. The Slot resource is used to define specific time intervals (slots) when appointments, such as consultations or tests, can be booked at a healthcare facility. Key elements include its identifier (id), metadata (meta), and essential service information. Specifically, mandatory fields include the 'schedule' reference indicating which schedule the slot belongs to, the status (status: busy, free, etc.), and temporal data such as the start (start) and end (end) times. Furthermore, detailed context regarding specific medical procedures is provided through elements like 'serviceType' (the type of bookable service), 'specialty' (required practitioner specialty), and 'appointmentType' (booking style). This allows the slot to provide more than just availability—it provides concrete context about the required healthcare action. These definitions are critical guidelines for designing advanced, interoperable healthcare IT systems in Japan, such as EHRs or regional medical networks. Developers can use this specification to standardize booking management functions and improve data exchange accuracy, considering the relationships with other related resources (e.g., Appointment, Schedule, Practitioner) for holistic system integration.
