Methods of Documentation VII: EMR

Methods of Documentation VII: EMR

Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Barriers to Effective Communication II

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Summary

Patient portal use in emergency departments (EDs) increased over time, but disparities persist. Emergency departments can help bridge this gap by enrolling and training patients to improve access and engagement.

Background:

Inequitable patient portal access is linked to increased emergency department (ED) utilization.
Understanding patient portal usage patterns within ED settings is crucial for improving care access.

Purpose of the Study:

To analyze real-time patient portal usage trends among ED patients.
To compare demographic and clinical characteristics of portal users versus non-users.

Main Methods:

A cross-sectional study evaluated patient portal access and usage data for over 1.2 million ED encounters across 8 health systems.
Data were collected from April 2021 to April 2022, focusing on real-time portal interactions like logging in, viewing test results, and clinical notes.
Pooled random-effects models assessed temporal trends and factors associated with portal use.

Main Results:

17.4% of patients logged into the patient portal during their ED visit; 14.1% viewed test results, and 2.5% viewed clinical notes.
Real-time portal access, test result viewing, and clinical note viewing increased significantly from the beginning to the end of the study period.
Patients with existing portal accounts showed substantially higher odds of engagement. Conversely, male, Black, and uninsured patients had lower odds of portal use.

Conclusions:

Real-time patient portal use in the ED is growing, yet significant disparities in access and utilization mirror broader trends.
Emergency departments present a key opportunity to enroll and educate patients on portal use, thereby enhancing engagement during and after visits.
Addressing these disparities is essential for equitable healthcare delivery and leveraging digital health tools.
