First Claim
1. A method comprising:
- processing, using a natural language understanding engine implemented by one or more processors, a first free-form narration, narrated by a clinician, of an encounter with a patient, the processing comprising;
detecting a mention in the first free-form narration of a first orderable item of a type selected from the group consisting of a medication, a clinical procedure, and a laboratory test;
performing a first semantic analysis of at least a part of the first free-form narration, wherein performing the first semantic analysis comprises;
determining a type of the first orderable item detected in the first free-form narration, wherein the determining is performed by the natural language understanding engine;
in response to determining that the type of the first orderable item is one of one or more first types, performing the first semantic analysis by applying a trained statistical model; and
in response to determining that the type of the first orderable item is one of one or more second types, performing the first semantic analysis by applying a rules-based system;
determining, based on the first semantic analysis, that the detected mention of the first orderable item is in a statement expressing that the clinician intends to order the first orderable item;
in response to determining that the detected mention of the first orderable item in the first free-form narration is in a statement expressing that the clinician intends to order the first orderable item, generating an order for the first orderable item; and
processing, using the natural language understanding engine implemented by the one or more processors, a second free-form narration, narrated by the clinician, of an encounter with the patient, the processing comprising;
detecting a mention in the second free-form narration of a second orderable item of the type selected from the group consisting of a medication, a clinical procedure, and a laboratory test;
performing a second semantic analysis of at least a part of the second free-form narration, wherein performing the first semantic analysis comprises;
determining a type of the second orderable item detected in the second free-form narration, wherein the determining is performed by the natural language understanding engine;
in response to determining that the type of the second orderable item is one of the one or more first types, performing the second semantic analysis by applying a trained statistical model; and
in response to determining that the type of the second orderable item is one of the one or more second types, performing the second semantic analysis by applying a rules-based system;
determining, based on the second semantic analysis, that the detected mention of the second orderable item is in a statement not expressing that the clinician intends to order the second orderable item; and
in response to determining that the detected mention of the second orderable item in the second free-form narration is in a statement not expressing that the clinician intends to order the second orderable item, not generating an order for the second orderable item.

Abstract
Techniques for determining a clinician'"'"'s intent to order an item may include processing a free-form narration, of an encounter with a patient, narrated by a clinician, using a natural language understanding engine implemented by one or more processors, to extract at least one clinical fact corresponding to a mention of an orderable item from the free-form narration. The processing may comprise distinguishing between whether the at least one clinical fact indicates an intent to order the orderable item or does not indicate an intent to order the orderable item. In response to determining that the at least one clinical fact indicates an intent to order the orderable item, an order may be generated for the orderable item.

10. Apparatus comprising:
-
at least one processor; and at least one processor-readable storage medium storing processor-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform a method comprising; processing, using natural language understanding, a first free-form narration, narrated by a clinician, of an encounter with a patient, the processing comprising; detecting a mention in the first free-form narration of an orderable item of a type selected from the group consisting of a medication, a clinical procedure, and a laboratory test; performing a first semantic analysis of at least a part of the first free-form narration, wherein performing the first semantic analysis comprises; determining a type of the first orderable item detected in the first free-form narration, wherein the determining is performed by the natural language understanding engine; in response to determining that the type of the first orderable item is one of one or more first types, performing the first semantic analysis by applying a trained statistical model; and in response to determining that the type of the first orderable item is one of one or more second types, performing the first semantic analysis by applying a rules-based system; determining, based on the first semantic analysis, whether the detected mention of the orderable item is in a statement expressing that the clinician intends to order the orderable item; and in response to determining that the detected mention of the orderable item in the first free-form narration is in a statement expressing that the clinician intends to order the orderable item, generating an order for the orderable item. - View Dependent Claims (11, 12, 13)
