使用 python hl7apy 在 ORU_R01 消息 hl7 中组合多个 OBX 段

Question

我正在尝试创建具有多个 OBX 段的 HL7 RU_R01 消息。但是，我找不到将这些片段合并到消息中的方法。

这是我的代码：

message = Message("ORU_R01", validation_level=VALIDATION_LEVEL.STRICT)
has_xxx_formatted = '2'

text_formatted = DEFAULT_HL7_TEXT["EN"]["XXXX"]

## MSH Segment
message.MSH.msh_3 = 'XXXXX'
message.msh.msh_4 = 'XXXXX'
message.msh.msh_9 = "ORU^R01^ORU_R01"
message.msh.msh_10 = ""
message.msh.msh_11 = ""

# patient details
message.ORU_R01_PATIENT_RESULT.ORU_R01_PATIENT.PID.pid_2 = "patient_id"
message.ORU_R01_PATIENT_RESULT.ORU_R01_PATIENT.PID.pid_3 = ""
message.ORU_R01_PATIENT_RESULT.ORU_R01_PATIENT.PID.pid_5 = ""

## OBR Segment -- frature details
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.OBR.obr_4 = "Observations"
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.OBR.obr_7 = f"{datetime.now().strftime('%Y%m%d%H%M%S.%f')[:-2]}"


# obx0
obx0 = Segment('OBX', version='2.5')
obx0.obx_1 = "1"
obx0.obx_2 = "HD"
obx0.obx_3 = "REFInstanceUID"
obx0.obx_5 = "ref_uid"
obx0.obx_11 = "F"

# obx1
obx1 = Segment('OBX', version='2.5')
obx1.obx_1 = "2"
obx1.obx_2 = "TX"
obx1.obx_3 = "Presence"
obx1.obx_5 = "XXXX"
obx1.obx_11 = "F"

# obx2
obx2 = Segment('OBX', version='2.5')
obx2.obx_1 = "3"
obx2.obx_2 = "TX"
obx2.obx_3 = "Result"
obx2.obx_5 = "XXXXX"
obx2.obx_11 = "F"

现在，如果我使用以下命令添加这些 obx 段：

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_OBSERVATION.OBX.obx_1 = 1
# adds individual values of obx0
....

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_OBSERVATION.OBX.obx_1 = 2
# adds individual values of obx1
....

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_OBSERVATION.OBX.obx_1 = 3
    # adds individual values of obx2
    ....

它只将最后一个 OBX 段添加到消息中。

如果我尝试按照here 的建议将转换 OBX 段添加到一个组中：

name = 'MDM_T02_OBXNTE_SUPPGRP'
mdm_group = Group(name, version='2.5')
mdm_group.obx = obx0
mdm_group.add(obx1)
mdm_group.add(obx2)

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_ORDER_OBSERVATION = mdm_group

我收到以下错误：

InvalidName：组名无效：MDM_T02_OBXNTE_SUPPGRP

我想知道如何在 OBR 之后将这些多个片段添加到单个消息中。提前谢谢你

我不知道 python 库，所以我无法为您提供确切的语法，但 ORU_R01_OBSERVATION 是一个可重复的字段，它允许单个 OBX 和多个 NTE 段。如果我猜测代码应该是这样的。

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_OBSERVATION[0].OBX.obx_1 = 1
# adds individual values of obx0
....

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_OBSERVATION[1].OBX.obx_1 = 2
# adds individual values of obx1
....

message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.ORU_R01_OBSERVATION[2].OBX.obx_1 = 3
    # adds individual values of obx2
    ....

似乎添加多个段的正确方法是将每个hl7apy.core.Segment 添加到它的单个hl7apy.core.Group。这在here 进行了解释，来自 hl7apy 的 java 版本的documentation 很有用。

message = Message("ORU_R01", validation_level=VALIDATION_LEVEL.TOLERATED)
has_xxx_formatted = '2'

text_formatted = DEFAULT_HL7_TEXT["EN"]["XXXX"]

## MSH Segment
message.MSH.msh_3 = 'XXXXX'
message.msh.msh_4 = 'XXXXX'
message.msh.msh_9 = "ORU^R01^ORU_R01"
message.msh.msh_10 = ""
message.msh.msh_11 = ""

# patient details
message.ORU_R01_PATIENT_RESULT.ORU_R01_PATIENT.PID.pid_2 = "patient_id"
message.ORU_R01_PATIENT_RESULT.ORU_R01_PATIENT.PID.pid_3 = ""
message.ORU_R01_PATIENT_RESULT.ORU_R01_PATIENT.PID.pid_5 = ""

## OBR Segment -- frature details
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.OBR.obr_4 = "Observations"
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.OBR.obr_7 = f"{datetime.now().strftime('%Y%m%d%H%M%S.%f')[:-2]}"

obs_name = 'ORU_R01_OBSERVATION'

# obx0
obx0_group = Group(obs_name, version='2.5')
obx0 = Segment('OBX', version='2.5')
obx0.obx_1 = "1"
obx0.obx_2 = "HD"
obx0.obx_3 = "REFInstanceUID"
obx0.obx_5 = "ref_uid"
obx0.obx_11 = "F"
obx0_group.add(obx0)
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.add(obx0_group)

# obx1
name = 'ORU_R01_OBSERVATION'
obx1_group = Group(obs_name, version='2.5')
obx1 = Segment('OBX', version='2.5')
obx1.obx_1 = "2"
obx1.obx_2 = "TX"
obx1.obx_3 = "Presence"
obx1.obx_5 = "XXXX"
obx1.obx_11 = "F"
obx1_group.add(obx1)
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.add(obx1_group)

# obx2
name = 'ORU_R01_OBSERVATION'
obx2_group = Group(obs_name, version='2.5')
obx2 = Segment('OBX', version='2.5')
obx2.obx_1 = "3"
obx2.obx_2 = "TX"
obx2.obx_3 = "Result"
obx2.obx_5 = "XXXXX"
obx2.obx_11 = "F"
obx2_group.add(obx2)
message.ORU_R01_PATIENT_RESULT.ORU_R01_ORDER_OBSERVATION.add(obx2_group)

另请注意，验证级别设置为可容忍TOLERATED。 STRICT 模式仅适用于单个 OBX 段。

现在验证工作。

assert hl7.validate() is True
