Schizophrenia Admission Incidence in North Wales Across Two Historical Periods

1875-1924 and 1994-2010 cohorts contain 3,523 total patient admissions from two North Wales psychiatric institutions. The data maps incidence of hospital admissions for schizophrenia and non-affective psychoses, revealing changes in admission rates and gender ratios over time. It was compiled by David Healy from archived patient case notes and modern hospital records.

Use Cases

• Analyze temporal trends in admission incidence for schizophrenia between the 1875-1924 and 1994-2010 cohorts.
• Compare admission rates for males versus females across the historical and modern periods to study shifting gender ratios.
• Investigate differences in admission patterns for schizophrenia relative to affective psychoses or organic disorders.
• Model the increase in admission incidence between 1875 and 1900 and the subsequent drop in rates after 2006.

Strengths

• Contains 3,523 patient admission records across two distinct historical periods.
• Epidemiologically complete cohorts from two specific psychiatric institutions in North Wales.
• Covers a broad time span, enabling analysis of long-term trends from 1875 to 2010.

Limitations

• Column names and specific data fields are unknown, limiting detailed feature analysis.
• Sample data and file formats are unavailable for preview, complicating usability assessment.
• The modern cohort (1994-2010) is significantly smaller (355 patients) than the historical one (3,168 patients), potentially limiting comparative power.
