[Radiologic performance in night and emergency care]

Area of Science:

• Radiology
• Medical Imaging
• Healthcare Management

Background:

• Radiologic examinations are crucial for patient diagnosis and management.
• Understanding the patterns of after-hours imaging is essential for resource allocation and staffing.
• The impact of government regulations on healthcare services requires continuous evaluation.

Purpose of the Study:

• To analyze the volume, characteristics, and trends of radiologic examinations performed outside official working hours.
• To assess the influence of new government regulations on these after-hours examinations.
• To compare the demographics and imaging modalities used in after-hours versus regular hours.

Main Methods:

• Retrospective analysis of 65,113 radiologic examinations performed outside official working hours over a 4-year period (July 1990 - June 1994).
• Data collected included patient demographics (age, sex), time of examination, organ systems, and radiologic techniques (CT, MRT, portable chest X-rays).
• Comparison of after-hours data with the overall patient population and examination trends.

Main Results:

• Approximately one-third of after-hours requests occurred between 4 PM and 8 PM, manageable by late shifts.
• Another third required in-house medical and technical staff between 8 PM and 8 AM.
• Portable chest examinations constituted the most frequent after-hours request (50% of all portable chest exams); CT and MRT accounted for 17.2% of all after-hours requests.

Conclusions:

• New government regulations did not alter the number, technique, or frequency of radiologic examinations conducted outside official working hours.
• A significant portion of after-hours imaging, particularly portable chest X-rays, necessitates dedicated staffing and resources.
• The findings highlight the consistent demand for radiologic services beyond standard working hours, irrespective of regulatory changes.
