Mental illness is the single largest cause of disability in the UK, with one in four individuals suffering from a mental health problem. Despite this, only 13% of the NHS budget goes towards treatment of mental illness. It is thus unsurprising that addressing the parity of esteem of mental health has been highlighted as a major priority for the healthcare system, with the NHS Five Year Forward plan aiming to achieve this by 2020.

To explore the barriers to achieving parity of esteem of mental healthcare in the UK and develop recommendations for implementation.

Narrative review of literature and synthesis of findings

Three key barriers to achieving parity of esteem of mental health were identified: the current mental health investment standard (MHIS), medical sub-specialisation, and access to acute day units (ADU). The following recommendations were thus synthesised: to increase the time-period to measure MHIS increments, integrating mental health teaching into specialty training programmes, and increasing the availbility of ADUs to crisis referral teams.

Addressing the disparity between mental and physical health is a major priority for the NHS. This research provides an overview of current barriers and suggests recommendations for improvement. By prioritizing improvement in the MHIS, integrating mental health teaching into specialty training, and increasing access to ADUs, the NHS formulates an excellent founding to achieving the ultimate goal, parity of esteem of mental health.

No significant relationships.

Recent qualitative research suggests that changes to the way eligibility for welfare payments is determined in the UK may be detrimental to claimants with mental illnesses. No large-scale analysis has been undertaken to date.

To examine differences between claimants with psychiatric conditions compared with non-psychiatric conditions in the number of claims disallowed following a personal independence payment (PIP) eligibility assessment for existing disability living allowance (DLA) claimants.

Administrative data on DLA claimants with psychiatric conditions transferring to PIP between 2013 and 2016 was compared with claimants with non-psychiatric conditions to explore differences in the number of claims disallowed following an eligibility assessment.

Claimants with a mental illness were 2.40 (95% CI 2.36–2.44) times more likely to have their existing DLA entitlement removed following a PIP eligibility assessment than claimants with musculoskeletal conditions, neurological conditions and diabetes.

PIP eligibility assessment outcomes show marked differences by health condition, raising questions as to whether the process is equitable.

None.
