Emergency department walk-in patients study

Area of Science:

• Emergency Medicine
• Public Health

Background:

• Walk-in patients constitute a significant portion (44%) of emergency department (ED) visits.
• Understanding the characteristics and outcomes of ED walk-in patients is crucial for resource allocation and service improvement.

Purpose of the Study:

• To characterize the demographic, clinical, and dispositional profiles of walk-in patients in a university hospital's ED.
• To compare the characteristics and outcomes of trauma versus medical walk-in patients.
• To identify patient groups requiring further investigation, such as those with ill-defined conditions.

Main Methods:

• A 25-week observational study of walk-in patients at a university hospital ED.
• Data collection utilized a Latin square method for time-based sampling (6-hour blocks).
• Included 1,800 walk-in patients, analyzing demographics, reason for visit (trauma/medical), referral source, symptom duration, and disposition.

Main Results:

• The walk-in population was predominantly male, under 40, and younger than the general population.
• Trauma patients (46%) typically presented within 3 hours, while medical patients (53%) often had longer symptom durations and were frequently referred by practitioners.
• Medical walk-ins had a significantly higher admission rate (47%) compared to trauma walk-ins (10%).
• Approximately 10% of walk-ins presented with 'symptoms, signs, and ill-defined conditions,' with 52% discharged home.

Conclusions:

• Medical walk-in patients represent a distinct group with a higher likelihood of admission, necessitating tailored ED management strategies.
• A notable proportion of walk-in patients present with non-specific symptoms, highlighting a need for further research into their care pathways and outcomes.
• The findings underscore the importance of differentiating between trauma and medical walk-ins for effective ED operations and patient management.
