[Validation of data on commitments to mental hospitals. How many persons were committed annually?]

Area of Science:

• Psychiatry
• Public Health
• Health Informatics

Context:

• The Danish Psychiatric Case Register and police statistics are vital for understanding mental health service utilization.
• Accurate data is essential for effective administration, planning, and research in mental healthcare.
• Previous studies have highlighted potential discrepancies in health record data.

Purpose:

• To validate the accuracy of data on psychiatric commitments recorded in the Danish Psychiatric Case Register against police statistics.
• To identify and quantify discrepancies between the two data sources.
• To assess the reliability of the Danish Psychiatric Case Register for research and administrative purposes.

Summary:

• A 1996 study analyzed 437 psychiatric commitments, finding police statistics more accurate than the Danish Psychiatric Case Register.
• Discrepancies included 13.7% of admissions misclassified between voluntary and involuntary status, with police data proving more accurate in medical record reviews.
• Insufficient reporting from psychiatric departments was identified as the primary cause for the register's inaccuracies.

Impact:

• The findings underscore the need for improved data reporting from psychiatric departments to enhance the Danish Psychiatric Case Register's reliability.
• Accurate psychiatric commitment data is critical for evidence-based policy-making and resource allocation in mental health services.
• This research provides a basis for improving health information systems and ensuring data integrity in mental healthcare.
