Traumatic Memory

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Background:

Traumatic subdural hematoma (TSDH) is a critical surgical condition.
The impact of weekend hospital admission on TSDH patient outcomes remains unclear.

Purpose of the Study:

To investigate the association between weekend admission and surgical intervention rates.
To evaluate the effect of weekend admission on in-hospital outcomes for TSDH patients.

Main Methods:

Analysis of Nationwide Inpatient Sample data (2002-2011) for TSDH admissions.
Identification of patients undergoing surgical evacuation for TSDH.
Multivariable analysis to assess weekend admission's impact on outcomes like complications, length of stay, cost, and mortality.

Main Results:

Weekend admissions were linked to reduced surgical intervention rates (OR: 0.85).
Weekend admissions showed increased in-hospital complications, prolonged length of stay, higher costs, adverse discharge, and mortality.
Despite higher severity in surgical cohorts, mortality rates were similar between weekend and weekday admissions.

Conclusions:

Weekend admission for TSDH is associated with poorer outcomes and increased costs.
No clinically significant weekend effect on mortality was observed for TSDH patients, despite higher severity on weekends.
