HL7段訂購

Question

我解析SIU S14具有以下段下令： MSH SCH PID PV1 RGS AIL AIS

，雖然它分析沒有錯誤，我不能檢索AIS段數據。但是當我在AIL之前移動AIS segement時，一切似乎都正常。那麼細分順序在HL7中是否重要？

Answer 1

HL7消息中段的順序由消息類型預先確定。在附表信息不請自來消息AIS段必須提前AIL。

SIU^S12-S24,S26,S27^SIU_S12: Schedule Information Unsolicited

MSH Message Header 
    SCH Schedule Activity Information  
    [ { TQ1 } ] Timing/Quantity  
    [ { NTE } ] Notes and Comments for the SCH 
    [ { --- PATIENT begin  
     PID Patient Identification 
     [ PD1 ] Additional Demographics  
     [ PV1 ] Patient Visit  
     [ PV2 ] Patient Visit - Additional Info  
     [ { OBX } ] Observation/Result  
     [ { DG1 } ] Diagnosis  
    } ] --- PATIENT end  
    {  --- RESOURCES begin  
    RGS  Resource Group Segment  
    [ { --- SERVICE begin  
     AIS  Appointment Information - Service  
     [ { NTE } ] Notes and Comments for the AIS  
    } ] --- SERVICE end  
    [ { --- GENERAL_RESOURCE begin  
     AIG  Appointment Information - General Resource  
     [ { NTE } ] Notes and Comments for the AIG  
    } ] --- GENERAL_RESOURCE end   
    [ { --- LOCATION_RESOURCE begin  
     AIL  Appointment Information - Location Resource   
     [ { NTE } ] Notes and Comments for the AIL  
    } ] --- LOCATION_RESOURCE end  
    [ { --- PERSONNEL_RESOURCE begin   
     AIP Appointment Information - Personnel Resource  
     [ { NTE } ] Notes and Comments for the AIP  
    } ] --- PERSONNEL_RESOURCE end  
    } --- RESOURCES end  

但是兩個區段分別他們的分段組是可選的。因此，只有AIL和AIS段的消息在語法上沒問題。當HL7消息打開時，在完整的消息之後允許附加或本地定義的段。爲了檢索這些額外的數據，您需要一個改編的模板。
