Introduction: • Contemporary issues • Speed of cultural changes in UK. • Individualistic ,competitive , materialistic, market driven. • Yet 25th Anniversary of the PBU! • NHS 65th anniversary! • EBM and VBM; evidence and Values. • Lack of relationship based Person Centered health care 1986
Screening: a misused and misunderstood word A public health service in which members of a defined population, who do not necessarily perceive that they are at risk of, or are already affected by a disease or its complications, are asked a question or offered a test to identify those individuals who are more likely to be helped than harmed by further tests or treatments reduce the risk of disease or its complications (National Screening Committee 2000) • Criteria for appraising programmes:
The Condition • An important health problem • Natural History of the condition understood. • All primary prevention interventions have been implemented
The Test • Simple Safe precise and validated • Acceptable to the population • Agreed policy on further diagnostic investigations following a positive screen.
The Treatment • An effective intervention. Evidence that early treatment is advantageous. • Evidence-based policies about which treatment option • Patient management options optimised prior to screening.
The Screening Programme • There must be evidence from the high quality RCTs that the screening programme is effective in reducing morbidity and mortality. • The programme is acceptable to the public and the professionals. • Benefits outweigh the risks
Values, ethics and humanity: EBM and VBM; clinical common-sense • National Institute of Clinical Excellence. Antenatal and Postnatal Mental Health Guidelines.
Severe mental illness Schizophrenia Bipolar disorder Depression Mild, moderate or severe Anxiety disorders Panic disorder Generalised anxiety disorder Obsessive–compulsive disorder (OCD) Post-traumatic stress disorder (PTSD) Eating disorders Mental disorders during pregnancy and the postnatal period
??? • Need to develop new classifications of • perinatal mental disorder ICD-11 and DSM-5 • eg mandatory 3 months specifier.
At first contact with maternity services, ask specific questions about: Past or present severe mental illness Previous treatment by psychiatrist/specialist mental health team Family history of perinatal mental illness Prediction
??? • Risk factors well-established for over 30 years. • Why have the midwifery profession and the medical profession not acted? • Why have obstetricians in the UK no postgraduate training in mental health?
Use the ‘Whooley’ questions at first contact with primary care, at the booking visit, and postnatally Other self-report measures can be used as part of subsequent assessment Identify possible depression Detection
??? • No established evidence-base for the Whooley questions yet! • Are they too woolly?! • Evidence for use of screening scales such as the EPDS considerably more conspicuous!
During the past month, have you often been bothered by feeling down, depressed or hopeless? During the past month, have you often been bothered by having little interest or pleasure in doing things? Consider a third question: Is this something you feel you need or want help with? The ‘Whooley’ questions
provide treatment within 1 month of initial assessment Subthreshold symptoms Previous depression or anxiety 4–6 sessions of brief psychological treatment such as interpersonal therapy (IPT) or cognitive behavioural therapy (CBT) No previous depression or anxiety Social support such as regular informal individual or group-based support Psychosocial treatments
Mild or moderate depression Self-help strategies Counselling (listening visits) Brief cognitive behavioural therapy Interpersonal psychotherapy Management of depression
??? • Is it the content of the therapy, or its regularity by a usually female professional, that is effective? • Is the health visitor, children’s nurse or psychologist providing the empathic support traditionally given by the mother?
Effective detection Effective assessment and referral to appropriate services Timely, appropriate management and treatment Accurate information about the disorder and the benefits and risks associated with interventions Provision of care in the most appropriate setting Appropriate communication about care with other services as required, taking into account confidentiality Choice Organisation of care
??? • Ethics of screening • National screening committee controversy with regard to the EPDS
Coordinating board Specialist perinatal services in each locality providing direct services, consultation and advice Access to specialist expert advice on psychotropic medication Clear referral and management protocols Clearly defined roles and competencies for all professional groups Clearly defined pathways of care for service users Service delivery:perinatal mental health networks

Identifying Perinatal Depression • Listen to what the mothers are telling you • ‘I have never felt like this before’ • It was ‘terrible’ ‘absolutely ghastly’ ‘something had got a hold’
