Symposium 33: ‘Big data’ and bipolar disorder in the UK
“A failure of social policy and health promotion, illness prevention and care provision.”
Life expectancy at birth of people with mental disorders in the period of 2007–09 (N = 31,719).
Chang C-K, Hayes RD, Perera G, Broadbent MTM, et al. (2011) Life Expectancy at Birth for People with Serious Mental Illness and Other Major
Disorders from a Secondary Mental Health Care Case Register in London. PLoS ONE 6(5): e19590. doi:10.1371/journal.pone.0019590
http://www.plosone.org/article/info:doi/10.1371/journal.pone.0019590
UK data:
• Bipolar Disorder Research Network (n=8,000)
• Scottish Primary Care data (n=1.8 million)
• UK Biobank (n=0.5 million)
• Glasgow Psychosis cohort (n=7,500)

The analysis of ‘SPICE data’ was conducted as part of the Living Well
with Multimorbidity Programme (CSO Grant ARPG/07/1) with
Professor SW Mercer (Principal Investigator) and Professor Bruce
Guthrie (epidemiology lead).
Multimorbidity and major mental illness in Scotland:
– Data from 314 general practices in Scotland (1.8 million people)
– Schizophrenia and related psychoses and bipolar disorder identified (n=12,504)
– 32 physical health conditions also identified
– Multimorbidity described by age, gender and socioeconomic deprivation
– Some prescribing information
Physical health comorbidities assessed:
Coronary heart
disease
Parkinson’s disease Peripheral vascular
disease
Viral hepatitis
Chronic kidney
disease
Multiple sclerosis Sinusitis Liver disease
Asthma Stroke Chronic obstructive
pulmonary disease
Psoriasis/eczema
Atrial fibrillation Blindness Bronchiectesis Irritable bowel

Epilepsy Glaucoma Crohn’s disease Migraine

Thyroid disorders Hypertension Rheumatoid

Implications:
• Coronary Heart Disease, Heart Failure, Peripheral Vascular
Disease, Stroke and TIA not more commonly recorded in the bipolar group
• Where cardiovascular diseases were recorded for the bipolar group, evidence of less intensive treatment
• Substantial treatment inequalities for bipolar patients with
coronary heart disease and hypertension.

Chronic multisite pain in major depression
and bipolar disorder: cross-sectional study of
149,612 participants in UK Biobank.
(Nicholl et al, under review)
• Definition of multisite pain:
“In the last month have you experienced any of the following
that interfered with your usual activities?”
– Headache pain
– Facial pain
– Neck or shoulder pain
– Back pain
– Stomach or abdominal pain
– Hip pain
– Knee pain
– “Pain all over the body” (widespread)
