Laboratory Testing Workflow (LTW) integrates the ordering, scheduling, processing, and result reporting activities associated with in vitro tests performed by clinical laboratories in healthcare institutions.
Summary
The Laboratory Testing Workflow Profile covers the workflow related to tests performed on in vitro specimens by a clinical laboratory inside a healthcare institution, for both existing and pending orders, related to identified patients and unidentified or misidentified patients. It specifies transactions that maintain the consistency of patient and order information from registration through ordering, scheduling, pre-analytical processing, testing, technical and clinical validation, to reporting and usage of test results by the care providers. This profile leverages IT Infrastructure profiles [PAM] or [PDQ] to rely on up to date patient and encounter data. This profile leverages IT Infrastructure profiles [ATNA] and [CT] for security.
Benefits
Reduces Errors and Enhance Patient Care
- Prevents manual data entry errors by ensuring that each piece of information is entered only once, by the person closest to the source of this information, and from there, made available in due time to any system who needs it.
- Reduce over-ordering and over blood sampling from the patient by letting the current lab orders and their results follow the movements of the patient from a ward to another.
- Accelerate the delivery of laboratory results to the ward staff, especially in emergency situations where a clinical decision is conditioned by some test results.
Improves Throughput in Care Process
- Suppresses manual order entry time on the laboratory side since the order is placed directly by the clinical system operated in the ward to the laboratory information system.
- Stremalines sample collection and transportation process, delivering a unique identifier to each specimen collected.
- Saves telephone calls between ward and laboratory since urgent results are delivered immediately and all status changes of any current order are reported in real time to the ordering system.
- Reduces the amount of paper reports since all lab results are consolidated in a global system that shares them with the authorized caregivers in the wards.
Favors independence of healthcare institution from their clinical and ancillary systems
- By providing clear specifications of interfaces between CIS, LIS and LAS, enables to replace one of these systems without breaking the existing data workflows.
