[The relationship between system overload and adverse events in obstetric services]

Area of Science:

• Obstetrics and Gynecology
• Patient Safety
• Healthcare Management

Background:

• Adverse events in healthcare can lead to severe patient outcomes, including death.
• Predicting patient volume and complexity in obstetric services is challenging for ensuring adequate staffing.
• Continuous around-the-clock staffing is crucial for managing obstetric emergencies.

Purpose of the Study:

• To investigate the relationship between patient arrival numbers and adverse events in obstetric care.
• To determine if adverse event rates correlate with specific shifts (day vs. night) or days of the week.
• To explore the potential impact of staff availability on adverse event occurrence.

Main Methods:

• Retrospective analysis of data from 2005-2006 at Ha'Emek hospital's risk management and delivery units.
• Comparison of patient arrival numbers and birth rates against reported adverse events.
• Specific examination of third and fourth-degree perineal tears during the 2005 delivery period.

Main Results:

• A total of 8,448 births were analyzed between 2005-2006.
• Significant variations in adverse event rates were observed across different days of the week (6.6%-11.9% per hundred births, P < 0.05).
• Third and fourth-degree perineal tears were notably higher during night shifts (0.24%-0.83%, P < 0.05).

Conclusions:

• The study highlights significant differences in adverse events based on day of the week and shift.
• Investigating reporting variations among staff members is necessary to understand day-of-week differences.
• Further research is needed to clarify the link between staffing levels, reporting, and adverse events in obstetric care.
