Summary
Comparing electronic health record (EHR) systems, Epic demonstrated superior usability over Cerner SurgiNet for patient order management (POM). This EHR conversion study highlights Epic's streamlined interface, reducing user burden and improving perioperative workflow efficiency.
Area of Science:
- Health Informatics
- Human-Computer Interaction
- Perioperative Medicine
Background:
- Patient order management (POM) is crucial for perioperative workflow but is often hindered by complex electronic health record (EHR) interfaces.
- Poor EHR usability increases documentation burden and impacts task efficiency.
Purpose of the Study:
- To compare the navigational complexity and usability of POM interfaces between two EHR systems: Cerner SurgiNet and Epic.
- To evaluate the impact of EHR conversion on user experience and task performance in perioperative settings.
Main Methods:
- Employed a navigational complexity framework.
- Utilized expert-based methods: functional analysis, Keystroke Level Model (KLM), and cognitive walkthrough.
- Conducted quantitative analysis of observed user behaviors.
Main Results:
- The Cerner SurgiNet interface had 12 unused POM functions, while Epic had 7.
- Epic exhibited a higher number of unused functions compared to Epic.
- Epic facilitated a more streamlined, task-focused user experience across all measures.
Conclusions:
- EHR interface design significantly impacts usability and task performance in perioperative patient order management.
- Epic offers a more user-friendly interface compared to Cerner SurgiNet, potentially reducing documentation burden.
- The navigational complexity framework effectively identifies usability barriers in EHR systems.

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.

01:22Routes of Drug Administration: Overview
7.8K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

01:45ER Retrieval Pathway
4.3K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
