Parity of Esteem in Practice: Closing the Physical Health Gap in Severe Mental Illness
Parity of esteem is often described as a principle. For providers working with severe mental illness, it must become operational reality. Within the Physical health, dual diagnosis and parity of esteem resources and the wider Mental health service models and pathways collection, the challenge is practical: people with severe mental illness experience significantly poorer physical health outcomes, yet monitoring, escalation and follow-through are inconsistent. Closing the gap requires structured screening, named accountability, and governance that proves actions were taken—not merely recorded.
Understanding the inequality in operational terms
People living with severe mental illness are more likely to experience diabetes, cardiovascular disease, respiratory illness and reduced life expectancy. In service terms, inequality shows up as missed checks, delayed GP contact, untreated side effects, and unrecognised deterioration masked by mental health symptoms.
Parity of esteem is achieved when these risks are managed with the same discipline as mental state relapse.
The parity operating framework
1) Routine physical health screening embedded into care planning
Screening must align to care plan reviews and medication changes, not be treated as an optional add-on. A defined checklist is embedded in review templates, with prompts for escalation and clear documentation fields.
2) Shared accountability across systems
Providers must clarify what they own and what primary care owns, ensuring no gaps. Consent-based information sharing and named contacts reduce ambiguity. Escalation timelines are written and reviewed in supervision.
3) Positive risk-taking with safeguarding awareness
Some people decline checks. Parity does not mean coercion. It means informed discussion, reasonable adjustments, repeated offers, and clear safeguarding escalation where self-neglect or deteriorating health presents unmanaged risk.
Operational examples (minimum three)
Operational example 1: Reducing avoidable admissions through proactive diabetes monitoring
Context: A person with schizophrenia and type 2 diabetes presents twice to A&E with hyperglycaemia linked to inconsistent medication and irregular meals.
Support approach: The service integrates diabetes monitoring into weekly support rather than treating it as separate medical territory.
Day-to-day delivery detail: Staff review blood glucose logs (where available), support structured meal planning, liaise with GP regarding medication adjustments, and document hydration routines. Missed GP reviews trigger same-week follow-up. A relapse trigger is added: significant appetite change or missed diabetes medication for more than 24 hours prompts escalation.
How effectiveness is evidenced: Evidence includes reduced emergency presentations over six months, improved HbA1c results, and documented coordination between mental health and primary care.
Operational example 2: Closing the gap in annual health checks
Context: Several service users have not completed annual physical health checks despite repeated reminders.
Support approach: The service treats low completion as a system failure requiring adjustment.
Day-to-day delivery detail: A register identifies who is overdue. Named workers contact individuals to identify barriers and offer accompaniment. Appointments are booked at quieter times. Outcomes are tracked weekly until completion. Where risk is high and engagement remains low, safeguarding considerations are documented and discussed in management review.
How effectiveness is evidenced: Completion rates increase over two quarters, and audit shows documented follow-up on abnormal findings rather than passive recording.
Operational example 3: Addressing respiratory risk in people who smoke
Context: High smoking prevalence in supported housing contributes to chronic cough and breathlessness, but it is treated as lifestyle choice rather than health risk.
Support approach: The service integrates smoking status into routine reviews and offers harm-reduction and cessation pathways without coercion.
Day-to-day delivery detail: Staff record smoking frequency at each review, provide practical information about nicotine replacement and local support, and monitor respiratory symptoms. Worsening breathlessness triggers GP referral. Progress is reviewed monthly, and small reductions are recognised.
How effectiveness is evidenced: Evidence includes documented smoking reduction in some individuals, earlier GP referrals for respiratory symptoms, and reduced unplanned urgent contacts.
Explicit expectations (mandatory)
Commissioner expectation
Commissioners typically expect providers to evidence reduced health inequality through measurable indicators: screening completion, timely escalation, reduced crisis use, and clear cross-system coordination. Reporting should show trends and action plans, not just activity volumes.
Regulator / Inspector expectation (e.g., CQC)
Inspectors typically expect safe, person-centred care that recognises physical health as integral to wellbeing. They will examine whether staff identify risk, make reasonable adjustments, escalate concerns appropriately, and evidence learning where harm occurs.
Governance and measurable impact
- Quarterly parity dashboard tracking screening rates, escalation timelines, and outcomes.
- Case-based audit reviewing closed-loop escalation in a sample of severe mental illness cases.
- Deterioration reviews ensuring physical health factors are examined after crisis events.
Parity of esteem becomes credible when operational systems make physical health risk visible, acted upon, and evidenced through measurable reduction in avoidable harm.
