A collaborative evaluation of remote consultations in mental health services was undertaken by mental health service providers, experts by experience, academic institutions and a Health Innovation Network in south London, UK. ‘Learning healthcare systems’ thinking was applied. Workstream 1 reviewed international published evidence; workstream 2 synthesised findings from three health provider surveys of the perceptions and experiences of staff, patients and carers; and workstream 3 comprised an electronic survey on local projects.
Results
Remote consultations can be acceptable to patients and staff. They improve access for some while restricting access for others, with digital exclusion being a key concern. Providing tailored choice is key.
Clinical implications
The collaboration generated learning to inform choices by healthcare providers to embed or adapt remote delivery. A key output was freely downloadable survey questions for assessing the quantity and quality of appointments undertaken by phone or video or face to face.
People with severe mental illness (SMI) have worse physical health than the general population. There is evidence that support from volunteers can help the mental health of people with SMI, but little evidence regarding the support they can give for physical health.
Aims
To evaluate the feasibility of an intervention where volunteer ‘Health Champions’ support people with SMI in managing their physical health.
Method
A feasibility hybrid randomised controlled trial conducted in mental health teams with people with SMI. Volunteers delivered the Health Champions intervention. We collected data on the feasibility of delivering the intervention, and clinical and cost-effectiveness. Participants were randomised by a statistician independent of the research team, to either having a Health Champion or treatment as usual. Blinding was not done.
Results
We recruited 48 participants: 27 to the intervention group and 21 to the control group. Data were analysed for 34 participants. No changes were found in clinical effectiveness for either group. Implementation outcomes measures showed high acceptability, feasibility and appropriateness, but with low response rates. No adverse events were identified in either group. Interviews with participants found they identified changes they had made to their physical health. The cost of implementing the intervention was £312 per participant.
Conclusions
The Health Champion intervention was feasible to implement, but the implementation of the study measures was problematic. Participants found the intervention acceptable, feasible and appropriate, and it led them to make changes in their physical health. A larger trial is recommended, with tailored implementation outcome measures.
While clozapine has risks, relative risk of fatality is overestimated. The UK pharmacovigilance programme is efficient, but comparisons with other drugs can mislead because of reporting variations. Clozapine actually lowers mortality, partly by reducing schizophrenia-related suicides, but preventable deaths still occur. Clozapine should be used earlier and more widely, but there should be better monitoring and better management of toxicity.

‘Psychotic disorders’ is an umbrella term for psychiatric conditions featuring psychosis, including mood disorders. Despite the prominence of psychotic symptoms across the psychotic spectrum, a distinction between schizophrenia and affective psychoses has been historically established. Findings from genetic studies support the aetiological overlap between affective and non-affective psychosis, although poor characterisation of the schizoaffective population still poses a challenge. Likewise, literature points to shared environmental risk factors between bipolar disorder and schizophrenia. Neuroimaging evidence suggest significant similarities in the pathophysiology of the brain between affective and non-affective psychosis. An overlap is also observed in other biological and behavioural illness markers, as well as in the pharmacotherapy of psychotic disorders. Current diagnostic entities may not accurately delineate the aetiology and pathophysiology of these conditions. Modern classification approaches, such as the RDoC framework, propose the adoption of aetiological factors and pathophysiological evidence to characterise patients, rather than categorical diagnoses based on symptoms.

The chapter describes the history, mechanisms and phases of drug treatment of antipsychotics including at-risk mental states (ARMS), first-episode psychosis (FEP), maintenance, treatment-resistant schizophrenia (TRS) and ultra-resistant psychosis. Specific treatments of schizoaffective disorder, catatonia and affective comorbidities of psychosis target negative symptoms and cognition. Rapid tranquilisation is described: general principles, de-escalation, routes of administration and medication selection. Management of organic psychotic disorders is discussed: general principles and specific conditions, epilepsy, Huntington’s, stroke, drug-induced, autoimmune encephalitis, inflammatory, CNS infections, thyroid disorders and traumatic brain injury. Side effects are elaborated: somnolence and sedation; hyperprolactinaemia and sexual dysfunction; motor, cardiac, metabolic and anticholinergic side effects; and also diabetes and impaired glucose tolerance and clozapine-specific side effects. Finally, potential drug interactions are explored.
Following the onset of the COVID-19 pandemic, healthcare trusts began to implement remote working arrangements, with little knowledge of their impact on staff well-being.
Aims
To investigate how remote working of healthcare workers during the pandemic may have been associated with stress, productivity and work satisfaction at that time, and associations between loneliness, workplace isolation, perceived social support and well-being.
Method
A questionnaire was developed to explore remote working and productivity, stress and work satisfaction during time spent working remotely. Associations between current loneliness, workplace isolation and well-being, and the influence of perceived social support, were explored with perceived social support as a potential moderator.
Results
A total of 520 participants responded to the study, of whom 112 were men (21.5%) and 406 were women (78.1%), with an age range of 21–77 years (mean 40.0, s.d. = 12.1). Very few (3.1%) worked remotely before the COVID-19 pandemic, and this had increased significantly (96.9%). Those who worked ≥31 h a week remotely reported higher stress and lower workplace satisfaction at that time, compared with office work, yet also felt more productive. Current loneliness, workplace isolation and perceived social support were cross-sectionally associated with lower current well-being.
Conclusions
Those who worked more hours a week remotely during the pandemic reported increased stress, which may be related to the lack of resources in place to support this change in work.
There are few data on the profile of those with serious mental illness (SMI) admitted to hospital for physical health reasons.
Aims
To compare outcomes for patients with and without an SMI admitted to hospital in England where the primary reason for admission was chronic obstructive pulmonary disease (COPD).
Method
This was a retrospective, observational analysis of the English Hospital Episodes Statistics data-set for the period from 1 April 2018 to 31 March 2019, for patients aged 18–74 years with COPD as the dominant reason for admission. Patient with an SMI (psychosis spectrum disorder, bipolar disorder) were identified.
Results
Data were available for 54 578 patients, of whom 2096 (3.8%) had an SMI. Patients with an SMI were younger, more likely to be female and more likely to live in deprived areas than those without an SMI. The burden of comorbidity was similar between the two groups. After adjusting for covariates, SMI was associated with significantly greater risk of length of stay than the median (odds ratio 1.24, 95% CI 1.12–1.37, P ≤ 0.001) and with 30-day emergency readmission (odds ratio 1.51, 95% confidence interval 1.34–1.69, P ≤ 0.001) but not with in-hospital mortality.
Conclusion
Clinicians should be aware of the potential for poorer outcomes in patients with an SMI even when the SMI is not the primary reason for admission. Collaborative working across mental and physical healthcare provision may facilitate improved outcomes for people with SMI.
To compare people with diabetes developing severe mental illness (SMI) to those with diabetes alone with respect to risk status, diabetes care receipt, and diabetes-relevant outcomes in primary care.
Methods
Data from mental health care (Clinical Record Interactive Search; CRIS) linked to primary care (Lambeth DataNet; LDN) were used. From patients with a type 2 diabetes mellitus (T2DM) diagnosis in primary care, those with a new SMI diagnosis were matched (by age, gender, and practice) with up to five randomly selected controls. Mixed models were used to estimate associations with trajectories of recorded HbA1c levels; Poisson regression models compared total and cardiovascular comorbidity levels and number of diabetes complications; linear regression models compared BMI and total cholesterol levels; conditional logistic regression models investigated microalbuminuria, receipt of a foot or retinal examination, use of statins and receipt of insulin; Cox proportional hazards were used to model incident microvascular and macrovascular events, foot morbidity and mortality.
Results
In a cohort of 693 cases with SMI (122 bipolar disorder, 571 schizophrenia and related) and T2DM compared to 3366 controls, all-cause mortality was increased substantially in the cohort with SMI (adjusted hazard ratio 4.52, 95% CI 3.73–5.47; for bipolar 5.59, 3.37–9.28; for schizophrenia 4.42, 3.60–5.44). However, for all the other outcome comparisons, the only significant findings were of reduced foot examination (adjusted odds ratio 0.75, 0.54–0.98) and reduced retinal screening (0.77, 0.61–0.96).
Conclusion
Higher mortality suggests increased risk of adverse outcomes for people with pre-existing T2DM who develop SMI, and reduced foot/retinal examinations suggest disadvantaged healthcare receipt. However, other potential explanations for the mortality difference could not be identified from the outcomes analysed, so further investigation is needed into underlying causal pathways.
Cannabis use has been linked to psychotic disorders but this association has been primarily observed in the Global North. This study investigates patterns of cannabis use and associations with psychoses in three Global South (regions within Latin America, Asia, Africa and Oceania) settings.
Methods
Case–control study within the International Programme of Research on Psychotic Disorders (INTREPID) II conducted between May 2018 and September 2020. In each setting, we recruited over 200 individuals with an untreated psychosis and individually-matched controls (Kancheepuram India; Ibadan, Nigeria; northern Trinidad). Controls, with no past or current psychotic disorder, were individually-matched to cases by 5-year age group, sex and neighbourhood. Presence of psychotic disorder assessed using the Schedules for Clinical Assessment in Neuropsychiatry and cannabis exposure measured by the World Health Organisation Alcohol, Smoking and Substance Involvement Screening Test (ASSIST).
Results
Cases reported higher lifetime and frequent cannabis use than controls in each setting. In Trinidad, cannabis use was associated with increased odds of psychotic disorder: lifetime cannabis use (adj. OR 1.58, 95% CI 0.99–2.53); frequent cannabis use (adj. OR 1.99, 95% CI 1.10–3.60); cannabis dependency (as measured by high ASSIST score) (adj. OR 4.70, 95% CI 1.77–12.47), early age of first use (adj. OR 1.83, 95% CI 1.03–3.27). Cannabis use in the other two settings was too rare to examine associations.
Conclusions
In line with previous studies, we found associations between cannabis use and the occurrence and age of onset of psychoses in Trinidad. These findings have implications for strategies for prevention of psychosis.
Patients with mental health disorders are known to have worse physical health outcomes. ‘Consultant Connect’ (CC) is an app-based communication platform which aims to improve patient outcomes and experience, by offering clinicians direct access to consultants working in a partnership acute Trust, so they can seek advice and guidance for their patients’ physical health problems. This creates whole system efficiencies by avoiding unnecessary referrals to an Emergency Department or outpatient clinics. This poster describes the implementation of CC in a large UK Mental Health Trust. Initially designed for GPs, this is the first time a UK Mental Health Trust has used CC.
Methods
Consultant Connect was launched in the Mental Health Trust's inpatient services in June 2020 as part of a Trust-wide programme of work aiming to improve the physical healthcare of mental health patients. In July 2021 it was rolled out across all services, including all community services. All platform activity was monitored and the implementation team collected data to determine: a) origin of call, b) which specialty was required, c) numbers of calls successfully connected, and in a subset of calls d) outcome of call. In addition, 183 call recordings were analysed, to identify clinical training needs and inform further development of the platform.
Results
In the period June 2020 – December 2021, there were 1422 use episodes of the CC platform by Mental Health Trust clinicians. There were 401 Trust registered downloads of the CC App by the Trust clinicians. 53 different clinical specialties were contacted, with cardiology (414 calls), diabetes and endocrinology (243 calls), and haematology (124 calls) the most frequently called. 68% of queries received a response. 48% of calls had an outcome recorded, with 70% of these resulting in the physical healthcare being delivered by the mental health team, following the advice received (i.e. referral or admission avoided, or the patient treated out of hospital).
Conclusion
CC is being progressively embedded into clinical practice and has become a well-used pathway for mental health clinicians seeking immediate clinical advice from acute hospital Consultant colleagues. Further qualitative and quantitative work is planned with mental health clinicians, patients and carers to better understand their experience and determine if it improves care from both the clinicians’ and patients’ perspective.
Clozapine is the only drug licensed for treatment-resistant schizophrenia (TRS) but the real-world clinical and cost-effectiveness of community initiation of clozapine is unclear.
Aims
The aim was to assess the feasibility and cost-effectiveness of community initiation of clozapine.
Method
This was a naturalistic study of community patients recommended for clozapine treatment.
Results
Of 158 patients recommended for clozapine treatment, 88 (56%) patients agreed to clozapine initiation and, of these, 58 (66%) were successfully established on clozapine. The success rate for community initiation was 65.4%; which was not significantly different from that for in-patient initiation (58.82%, χ2(1,88) = 0.47, P = 0.49). Following clozapine initiation, there was a significant reduction in median out-patient visits over 1 year (from 24.00 (interquartile range (IQR) = 14.00–41.00) to 13.00 visits (IQR = 5.00–24.00), P < 0.001), and 2 years (from 47.50 visits (IQR = 24.75–71.00) to 22.00 (IQR = 11.00–42.00), P < 0.001), and a 74.71% decrease in psychiatric hospital bed days (z = −2.50, P = 0.01). Service-use costs decreased (1 year: –£963/patient (P < 0.001); 2 years: –£1598.10/patient (P < 0.001). Subanalyses for community-only initiation also showed significant cost reductions (1 year: –£827.40/patient (P < 0.001); 2 year: –£1668.50/patient (P < 0.001) relative to costs prior to starting clozapine. Relative to before initiation, symptom severity was improved in patients taking clozapine at discharge (median Positive and Negative Syndrome Scale total score: initial visit: 80 (IQR = 71.00–104.00); discharge visit 50.5 (IQR = 44.75–75.00), P < 0.001) and at 2 year follow-up (Health of Nation Outcome Scales total score median initial visit: 13.00 (IQR = 9.00–15.00); 2 year follow-up: 8.00 (IQR = 3.00–13.00), P = 0.023).
Conclusions
These findings indicate that community initiation of clozapine is feasible and is associated with significant reductions in costs, service use and symptom severity.
People with psychosis experience cardiometabolic comorbidities, including metabolic syndrome, coronary heart disease and diabetes. These physical comorbidities have been linked to diet, inactivity and the effects of the illness itself, including disorganisation, impairments in global function and amotivation associated with negative symptoms of schizophrenia or co-morbid depression.
Methods
We aimed to describe the dietary intake, physical activity (PA) and sedentary behaviour patterns of a sample of patients with established psychosis participating in the Improving Physical Health and Reducing Substance Use in Severe Mental Illness (IMPaCT) randomised controlled trial, and to explore the relationship between these lifestyle factors and mental health symptomatology.
Results
A majority of participants had poor dietary quality, low in fruit and vegetables and high in discretionary foods. Only 29.3% completed ⩾150 min of moderate and/or vigorous activity per week and 72.2% spent ⩾6 h per day sitting. Cross-sectional associations between negative symptoms, global function, and PA and sedentary behaviour were observed. Additionally, those with more negative symptoms receiving IMPaCT therapy had fewer positive changes in PA from baseline to 12-month follow-up than those with fewer negative symptoms at baseline.
Conclusion
These results highlight the need for the development of multidisciplinary lifestyle and exercise interventions to target eating habits, PA and sedentary behaviour, and the need for further research on how to adapt lifestyle interventions to baseline mental status. Negative symptoms in particular may reduce patient's responses to lifestyle interventions.
High intensity interval training (HIIT) may improve a range of physical and mental health outcomes among people with severe mental illnesses (SMI). However, there is limited data on patients’ reported attitudes towards HIIT and its implementation within inpatient settings, and there remains an absence of data on attitudes towards HIIT from informal family carers of service users and healthcare professionals, who both have key roles to play in facilitating recovery outcomes in service users. This study sought to qualitatively investigate, in inpatients with SMI, carer and staff groups, perspectives on implementing HIIT interventions for patient groups in inpatient settings.
Method
Seven focus groups and one individual interview were conducted. These included three focus groups held with inpatients with SMI (n = 12), two held with informal carers (n = 15), and two held with healthcare professionals working in inpatient settings (n = 11). An additional individual interview was conducted with one patient participant. The focus group schedule comprised open- ended questions designed to generate discussion and elicit opinions surrounding the introduction of HIIT on inpatient mental health wards. Data were subject to a thematic analysis.
Result
Two key themes emerged from the data, across all participants, that reflected the ‘Positivity’ in the application of HIIT interventions in psychiatric inpatient settings with beliefs that it would help patients feel more relaxed, build their fitness, and provide a break from the monotony of ward environment. Moreover, the short length of HIIT sessions was deemed appealing to mitigate against difficulties that many inpatients can experience with motivation, interest and attention, and was considered to be more appealing than more lengthy forms of exercise, which may require greater physical exertion. The second theme related to ‘Implementation concerns’, that reflected subthemes about i) low patient motivation, particularly with older participants, those administered many medications, and for those with less positive memories of exercise ii) patient safety, including concerns surrounding the intensity of HIIT and inclusion of patients with physical health comorbidities and iii) practical logistical factors, including having access to the right sports clothing and staff availability to supervise HIIT.
Conclusion
HIIT for inpatients with SMI was actively endorsed by patients, carers and healthcare professionals. Patient safety and baseline motivation levels, and practical service considerations were all noted as potential barriers to successful implementation and are worth considering in preparation for trialing a new intervention.
A possible role of vitamin D in the pathophysiology of depression is currently speculative, with more rigorous research needed to assess this association in large adult populations. The current study assesses prospective associations between vitamin D status and depression in middle-aged adults enrolled in the UK Biobank.
Methods
We assessed prospective associations between vitamin D status at the baseline assessment (2006–2010) and depression measured at the follow-up assessment (2016) in 139 128 adults registered with the UK Biobank.
Results
Amongst participants with no depression at baseline (n = 127 244), logistic regression revealed that those with vitamin D insufficiency [adjusted odds ratio (aOR) = 1.14, 95% confidence interval (CI) = 1.07–1.22] and those with vitamin D deficiency (aOR = 1.24, 95% CI 1.13–1.36) were more likely to develop new-onset depression at follow-up compared with those with optimal vitamin D levels after adjustment for a wide range of relevant covariates. Similar prospective associations were reported for those with depression at baseline (n = 11 884) (insufficiency: aOR = 1.11, 95% CI 1.00–1.23; deficiency: aOR = 1.30, 95% CI 1.13–1.50).
Conclusions
The prospective associations found between vitamin D status and depression suggest that both vitamin D deficiency and insufficiency might be risk factors for the development of new-onset depression in middle-aged adults. Moreover, vitamin D deficiency (and to a lesser extent insufficiency) might be a predictor of sustained depressive symptoms in those who are already depressed. Vitamin D deficiency and insufficiency is very common, meaning that these findings have significant implications for public health.
Treatment-resistant schizophrenia is a major disabling illness which often proves challenging to manage in a secondary care setting. The National Psychosis Unit (NPU) is a specialised tertiary in-patient facility that provides evidence-based, personalised, multidisciplinary interventions for complex treatment-resistant psychosis, in order to reduce the risk of readmission and long-term care costs.
Aims
This study aimed to assess the long-term effectiveness of treatment at the NPU by considering naturalistic outcome measures.
Method
Using a mirror image design, we compared the numbers of psychiatric and general hospital admissions, in-patient days, acuity of placement, number of psychotropic medications and dose of antipsychotic medication prescribed before and following NPU admission. Data were obtained from the Clinical Records Interactive Search system, an anonymised database sourced from the South London and Maudsley NHS Trust electronic records, and by means of anonymous linkage to the Hospital Episode Statistics system.
Results
Compared with the 2 years before NPU admission, patients had fewer mental health admissions (1.65 ± 1.44 v. 0.87 ± 0.99, z = 5.594, P < 0.0001) and less mental health bed usage (335.31 ± 272.67 v. 199.42 ± 261.96, z = 5.195 P < 0.0001) after NPU admission. Total in-patient days in physical health hospitals and total number of in-patient days were also significantly reduced (16.51 ± 85.77 v. 2.83 ± 17.38, z = 2.046, P = 0.0408; 351.82 ± 269.09 v. 202.25 ± 261.05, z = 5.621, P < 0.0001). The reduction in level of support required after treatment at the NPU was statistically significant (z = −8.099, P < 0.0001).
Conclusions
This study demonstrates the long-term effectiveness of a tertiary service specialising in treatment-resistant psychosis.
Clozapine is uniquely effective in treatment-resistant psychosis but remains underutilised, partly owing to psychotic symptoms leading to non-adherence to oral medication. An intramuscular formulation is available in the UK but outcomes remain unexplored.
Aims
This was a retrospective clinical effectiveness study of intramuscular clozapine prescription for treatment initiation and maintenance in treatment-resistant psychosis over a 3-year period.
Method
Successful initiation of oral clozapine after intramuscular prescription was the primary outcome. Secondary outcomes included all-cause clozapine discontinuation 2 years following initiation, and 1 year after discharge. Discontinuation rates were compared with a cohort prescribed only oral clozapine. Propensity scores were used to address confounding by indication.
Results
Among 39 patients prescribed intramuscular clozapine, 19 received at least one injection, whereas 20 accepted oral clozapine when given an enforced choice between the two. Thirty-six (92%) patients successfully initiated oral clozapine after intramuscular prescription; three never transitioned to oral. Eight discontinued oral clozapine during the 2-year follow-up, compared with 83 out of 162 in the comparator group (discontinuation rates of 24% and 50%, respectively). Discontinuation rates at 1-year post-discharge were 21%, compared with 44% in the comparison group. Intramuscular clozapine prescription was associated with a non-significantly lower hazard of discontinuation 2 years after initiation (hazard ratio 0.39, 95% CI 0.14–1.06) and 1 year after discharge (hazard ratio 0.37, 95% CI 0.11–1.24). The only reported adverse event specific to the intramuscular formulation was injection site pain and swelling.
Conclusions
Intramuscular clozapine prescription allowed transition to oral maintenance in an initially non-adherent cohort. Discontinuation rates were similar to patients only prescribed oral clozapine and comparable to existing literature.
The first episode of psychosis is a critical period in the emergence of cardiometabolic risk.
Aims
We set out to explore the influence of individual and lifestyle factors on cardiometabolic outcomes in early psychosis.
Method
This was a prospective cohort study of 293 UK adults presenting with first-episode psychosis investigating the influence of sociodemographics, lifestyle (physical activity, sedentary behaviour, nutrition, smoking, alcohol, substance use) and medication on cardiometabolic outcomes over the following 12 months.
Results
Rates of obesity and glucose dysregulation rose from 17.8% and 12%, respectively, at baseline to 23.7% and 23.7% at 1 year. Little change was seen over time in the 76.8% tobacco smoking rate or the quarter who were sedentary for over 10 h daily. We found no association between lifestyle at baseline or type of antipsychotic medication prescribed with either baseline or 1-year cardiometabolic outcomes. Median haemoglobin A1c (HbA1c) rose by 3.3 mmol/mol in participants from Black and minority ethnic (BME) groups, with little change observed in their White counterparts. At 12 months, one-third of those with BME heritage exceeded the threshold for prediabetes (HbA1c >39 mmol/mol).
Conclusions
Unhealthy lifestyle choices are prevalent in early psychosis and cardiometabolic risk worsens over the next year, creating an important window for prevention. We found no evidence, however, that preventative strategies should be preferentially directed based on lifestyle habits. Further work is needed to determine whether clinical strategies should allow for differential patterns of emergence of cardiometabolic risk in people of different ethnicities.
