BI Directional API Applications in Healthcare

Jul 16, 2021

As most of the clinical determinations are based on lab tests, interfacing labs with EMR systems is essential to secure connectivity with healthcare providers to develop workflow, productivity and degree of care. Physicians are also obligated to transfer orders electronically as part of the meaningful use condition and obtain test results undeviatingly in their EMR systems.

When a medical practice uses an EHR, a lab interface is part of the software that enables one system to talk to another. A laboratory interface can be either uni-directional (allowing the lab to record the lab data straight to the EHR) or bi-directional (allowing the clinician to manage the lab investigation and accept the itemized data electronically in the EHR). With a bi-directional interface, the entire process is electronic, from when the lab investigation is ordered to the resulting arrival in the patient’s electronic record.

Nature of Bi-Directional Interface

A bidirectional interface heightens the fluid transfer of patient information, analysis orders, results, and other vital aspects to and from clinics, labs, and land registries.

It develops workflow and productivity by practically reducing test code errors, electronically routing back decisions to individual physicians, and helping trace rebuffs and management status. The systemized method diminishes effort and costs considerably by excluding manifold interfaces needed to correlate diverse EMR systems.

Virtually, bi-directional functionality eradicates the demand for manual data variations and significantly lessens the rate of errors produced by out-of-date or out-of-sync data. Patients traveling between healthcare providers can have peace of mind, recognizing that their health data is always reachable via reliable lines of communication.

Bidirectional Benefits for Healthcare Practice

Communication is the lifeblood of effective healthcare distribution. When clinicians can share data efficiently with lab technicians, the quality of care improves.

1. Real-time Exchange of Patient Data

Healthcare providers require a bi-directional interface to circumvent burnout. Employing uni-directional interfaces puts doctors at a loss. They will need to keep giving and getting information to convey lab orders and collect the test results. Consequently, it will spell concern for patients due to the generated data lag.

When each stakeholder has access to the most up-to-date data by exercising bi-directional interfaces, errors can be classified more swiftly and acknowledged promptly. Furthermore, an integrated operation decreases wait times, empowering patients to access their results via a patient gateway and understand the data before going over it with a practitioner.

2. Exclusion of Unnecessary Lab Orders

Needless inpatient laboratory orders are a persistent dilemma in many healthcare teams. It’s a significant waste source for the patients and providers, with advanced communication restricting redundant lab orders. A bi-directional interface enables physicians to communicate immediately with lab professionals in real-time.

They can ask inquiries about a test event, and the lab technicians will present observations to help clinicians make more intelligent diagnostic verdicts. Since each person included in managing tests, testing, or communicating results has a passage to the bi-directional interface, there’s no call for any redundant data exchanges.

3. Exclusion of Errors

Many features and fine details influence the nature and timeliness of test results. The patient’s demographics, such as name, age, blood group, gender, bill number, sample type, list of tests, and an individual patient ID, must be communicated precisely to the laboratory. These aspects are captured in the lab data management operation along with test outcomes.

Utilizing a bi-directional interface makes it feasible to associate the test results and analysis directly to the test order and patient accounts without any mismatch or inaccuracies. It reduces the mental strain on the physician and lab professional and elevates the quality of care experienced by the patient.

4. Augmentation of Value-based Care

When bi-directional interfaces consolidate with HL7 interfaces, providers and labs can correlate anywhere around the globe. In addition to implementing fundamental care for patients when they are not in the same region as their principal care provider, bi-directional communication also empowers providers and labs to add to health trade-offs and develop an active health data system.


Bi-directional order management streamlines processes, boosts productivity and checks expenses. These advantages add up to a safer, more dynamic patient encounter. And when patients experience metrics better, there will be many more possibilities to bolster patient satisfaction standards. An organized enterprise to develop methods can have a definite and decisive impression on patient outcome metrics.
