Background:

Effective patient care in psychogeriatric units relies on timely access to laboratory test results.
Traditional methods of reporting lab results can be inefficient and prone to delays.
Computerized systems offer potential for improved workflow and patient safety.

Purpose of the Study:

To evaluate the impact of a computerized laboratory alerting system on patient care within a psychogeriatric unit.
To assess the efficiency and effectiveness of automated lab result reporting.
To determine the system's contribution to clinical decision-making and patient safety.

Main Methods:

A 34-bed psychogeriatric unit implemented a computerized laboratory alerting system.
Routine laboratory test results were automatically retrieved and registered on daily medication reports.
A senior psychiatrist monitored system performance, message types, and clinical actions for 33 days.

Main Results:

The system generated an average of 0.77 messages per patient daily.
Twelve percent of messages were new alerts, while 88% were rotating updates.
Physician unawareness affected 6% of all messages; 7% of new alerts prompted treatment, and 15% led to retesting.

Conclusions:

The computerized alerting system provides a simple and efficient report.
The system substantially contributes to safe patient care in psychogeriatric settings.
Automated lab result integration enhances clinical oversight and timely interventions.
