Beschreibung This element encodes the start and stop time of the medication regimen. This is an interval of time (xsi:type='IVL_TS'), and must be specified as shown. This is an additional constraint placed upon CDA Release 2.0 by this profile, and simplifies the exchange of start/stop and frequency information between EMR systems.

Item DT Kard Konf Beschreibung Label Auswahl 1 … 1 The effectiveTime element encodes the use period of the medication, it is always expressed as an interval of time. It may be expressed using the low and high OR with the width element. The first is used to indicate a specified interval (e.g. from march 15th, 2017); the latter for indicating a 'floating' period (e.g. 2 weeks). Elemente in der Auswahl: hl7:effectiveTime[hl7:low | hl7:high][not(hl7:width)] hl7:effectiveTime[hl7:width][not(hl7:low|hl7:high)] hl7:effectiveTime[hl7:low | hl7:width][not(hl7:high)] hl7:effectiveTime IVL_TS 0 … 1 C Case 1: specified interval The low and high values of the first effectiveTime element represent the start and stop times for the medication. The low value represents the start time, and the high value represents the stop time. If either the low or the high value is unknown, this shall be recorded by setting the nullFlavor attribute to UNK. In case of unbounded period (continuous therapy) the high element will be valued with the nullFlavor attribute to NA. The high value records the end of the medication regime according to the information provided in the prescription or order. For example, if the prescription is for enough medication to last 30 days, then the high value should contain a date that is 30 days later then the low value. The rationale is that a provider, seeing a prescription that has not been refilled would normally assume that the medication is no longer being taken, even if the intent of the treatment plan is to continue the medication indefinitely. wo [hl7:low oder [not(hl7:width)] @nullFlavor cs 0 … 1     Beispiel Known Interval <effectiveTime type="IVL_TS">   <low value="20130321"/>  <high value="20140321"/></effectiveTime>   Beispiel Information not available about the period <effectiveTime type="IVL_TS" nullFlavor="NI"/>   Beispiel Unknown end date <effectiveTime type="IVL_TS">   <low value="20130321"/>  <high nullFlavor="UNK"/></effectiveTime>   Beispiel continous therapy <effectiveTime type="IVL_TS">   <low value="20130321"/>  <high nullFlavor="NA"/></effectiveTime> hl7:low IVXB_TS 1 … 1 R hl7:high IVXB_TS 0 … 1 R hl7:effectiveTime IVL_TS 0 … 1 C Case 2: 'floating' period: The width element is used to specify a period of (actual or intended) administration that is not anchored to any specific date (e.g. a two weeks therapy) wo [hl7:width] [not(hl7:lowoder hl7:high)]   Beispiel 2 week period <effectiveTime type="IVL_TS">   <width value="2" unit="w"/></effectiveTime> hl7:low NP hl7:high NP hl7:center NP hl7:width PQ 1 … 1 R @unit cs 1 … 1 R   CONF Der Wert von @unit MUSS gewählt werden aus dem Value Set 2.16.840.1.113883.11.21.1 Medication Time Units (UCUM) (DYNAMIC) hl7:effectiveTime IVL_TS 0 … 1 C Case 3: anchored period: The width element is used to specify a period of (actual or intended) administration anchored to a specific date (e.g. a two weeks therapy starting today) wo [hl7:low oder [not(hl7:high)]   Beispiel 2 week period starting on 2013-03-21 <effectiveTime type="IVL_TS">   <low value="20130321"/>  <width value="2" unit="w"/></effectiveTime> hl7:low IVXB_TS 0 … 1 C hl7:width PQ 1 … 1 R @unit cs 1 … 1 R   CONF Der Wert von @unit MUSS gewählt werden aus dem Value Set 2.16.840.1.113883.11.21.1 Medication Time Units (UCUM) (DYNAMIC)
