Data Type Profile: TimingDE - Detailed Descriptions

Draft as of 2025-07-11

Definitions for the TimingDE data type profile.

Guidance on how to interpret the contents of this table can be foundhere

0. Timing
Definition

Specifies an event that may occur multiple times. Timing schedules are used to record when things are planned, expected or requested to occur. The most common usage is in dosage instructions for medications. They are also used when planning care of various kinds, and may be used for reporting the schedule to which past regular activities were carried out.

ShortA timing schedule that specifies an event that may occur multiple times
Comments

Describes the occurrence of an event that may occur multiple times. Timing schedules are used for specifying when events are expected or requested to occur, and may also be used to represent the summary of a past or ongoing event. For simplicity, the definitions of Timing components are expressed as 'future' events, but such components can also be used to describe historic or ongoing events.

A Timing schedule can be a list of events and/or criteria for when the event happens, which can be expressed in a structured form and/or as a code. When both event and a repeating specification are provided, the list of events should be understood as an interpretation of the information in the repeat structure.

Control0..*
This element is affected by the following invariants: ele-1
Invariantsele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
2. Timing.modifierExtension
Definition

May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

ShortExtensions that cannot be ignored even if unrecognized
Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Requirements

Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

tim-6: If there's a periodMax, there must be a period (periodMax.empty() or period.exists())
tim-7: If there's a durationMax, there must be a duration (durationMax.empty() or duration.exists())
tim-8: If there's a countMax, there must be a count (countMax.empty() or count.exists())
tim-1: if there's a duration, there needs to be duration units (duration.empty() or durationUnit.exists())
tim-10: If there's a timeOfDay, there cannot be a when, or vice versa (timeOfDay.empty() or when.empty())
tim-2: if there's a period, there needs to be period units (period.empty() or periodUnit.exists())
tim-4: duration SHALL be a non-negative value (duration.exists() implies duration >= 0)
6. Timing.repeat.bounds[x]
Definition

Either a duration for the length of the timing schedule, a range of possible length, or outer bounds for start and/or end limits of the timing schedule.

To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

            There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

              Requirements

              Timings are frequently determined by occurrences such as waking, eating and sleep.

              60. Timing.repeat.offset
              Definition

              The number of minutes from the event. If the event code does not indicate whether the minutes is before or after the event, then the offset is assumed to be after the event.

              62. Timing.code
              Definition

              A code for the timing schedule (or just text in code.text). Some codes such as BID are ubiquitous, but many institutions define their own additional codes. If a code is provided, the code is understood to be a complete statement of whatever is specified in the structured timing data, and either the code or the data may be used to interpret the Timing, with the exception that .repeat.bounds still applies over the code (and is not contained in the code).

              Comments

              BID etc. are defined as 'at institutionally specified times'. For example, an institution may choose that BID is "always at 7am and 6pm". If it is inappropriate for this choice to be made, the code BID should not be used. Instead, a distinct organization-specific code should be used in place of the HL7-defined BID code and/or a structured representation should be used (in this case, specifying the two event times).
