Outcome Measures
Primary Outcome Measures
- Describe the prevalence of common mental health conditions in adults diagnosed with vitiligo and matched controls without vitiligo [At the time of diagnosis in all people diagnosed with vitiligo 2004-2020 inclusive. For matched controls, the date of diagnosis of their matched case.]
Prevalence of common mental health conditions (depressive episodes, recurrent depressive disorder and anxiety disorder) in adult people diagnosed with vitiligo.
- Describe the incidence of common mental health conditions in adults diagnosed with vitiligo and matched controls without vitiligo [Within two years of vitiligo diagnosis. For matched controls, within two years of the date of diagnosis of their matched case.]
Incidence of common mental health conditions (depressive episodes, recurrent depressive disorder and anxiety disorder) in adult people with vitiligo in a contemporary real-world population compared with matched controls.
- Describe healthcare utilisation in adults with incident (new onset) vitiligo and matched controls without vitiligo [Within one year of vitiligo diagnosis. For matched controls, within one year of the date of diagnosis of their matched case.]
Healthcare utilisation comprises of number of primary care visits.
- Describe mental health management patterns in adults with vitiligo and mental health conditions (depressive episodes, recurrent depressive disorder and anxiety disorder) [Within one year of vitiligo diagnosis. For matched controls, within one year of the date of diagnosis of their matched case.]
Mental health management comprises of referrals for cognitive behavioural therapy, counselling, psychotherapy, psychiatry, and other psychological intervention either through direct referral or the Improving Access to Psychological Therapies (IAPT) services programme.
- Describe the burden of 'sick days' and unemployment in adult people of normal working age diagnosed with vitiligo and matched controls without vitiligo [Within one year of vitiligo diagnosis.]
Sick days will be indicated by the issuing of Med 3 certification from primary care (Statement of Fitness for Work) certification. Unemployment will be identified using Read codes relating to unemployment recorded in the clinical record or the issuing of an Incapacity Benefit (IB113) or Employment and Support Allowance (ESA113) form. Normal working age is defined as aged 18 - 65 years.
- Describe other potential psychological complications in adult people diagnoses with vitiligo and matched controls without vitiligo [Within one year of vitiligo diagnosis.]
Psychological complications comprises of social phobia, adjustment disorder, substance abuse, self-harm, overdose, and parasuicide or suicide attempts.
Secondary Outcome Measures
- Describe the incidence of common mental health conditions (depressive episodes, recurrent depressive disorder and anxiety disorder) in adult people with vitiligo stratified by sociodemographic factors compared to matched controls. [Within two years of vitiligo diagnosis. For matched controls, within two years of the date of diagnosis of their matched case.]
Sociodemographic groups are defined by 10-year age category, sex, socio-economic status and ethnicity.
