    Rapid tranquillisation for psychiatric in-patients with a diagnosis of personality disorder: under-recognised issue

    by Carol Paton, Mike J. Crawford, Matthew Hartley, Clive E. Adams, Elena M. Edokpolor Pernia, Olivia Rendora, Thomas R. E. Barnes

    Background: Clinical guidelines for personality disorder emphasise the importance of patients being supported to develop psychological skills to help them manage their symptoms and behaviours. But where these mechanisms fail, and hospital admission occurs, little is known about how episodes of acutely disturbed behaviour are managed. Aims: To explore the clinical characteristics and management of episodes of acutely disturbed behaviour requiring medication in in-patients with a diagnosis of personality disorder. Method: Analysis of clinical audit data collected in 2024 by the Prescribing Observatory for Mental Health, as part of a quality improvement programme addressing the pharmacological management of acutely disturbed behaviour. Data were collected from clinical records using a bespoke proforma. Results: Sixty-two mental health Trusts submitted data on 951 episodes of acutely disturbed behaviour involving patients with a personality disorder, with this being the sole psychiatric diagnosis in 471 (50%). Of the total, 782 (82%) episodes occurred in female patients. Compared with males, episodes in females were three times more likely to involve self-harming behaviour or be considered to pose such a risk (22% and 70% respectively: p < 0.001). Parenteral medication (rapid tranquillisation) was administered twice as often in episodes involving females than in males (64 and 34% respectively: p < 0.001). Conclusions: Our findings suggest that there are a large number of episodes of acutely disturbed behaviour on psychiatric wards in women with a diagnosis of personality disorder. These episodes are characterised by self-harm and regularly prompt the administration of rapid tranquillisation. This has potential implications for service design, staff training, and research.

    Understanding the medication regimens associated with anticholinergic burden in older people's mental health services in the UK

    by Thomas R. E. Barnes, Delia Bishara, Alistair Burns, Phyo K. Myint, Olivia Rendora, Elena M. Edokpolor Pernia, Carol Paton

    Background: Medications with anticholinergic properties are associated with a range of adverse effects that tend to be worse in older people. Aims: To investigate medication regimens with high anticholinergic burden, prescribed for older adults under the care of mental health services. Method: Clinical audit of prescribing practice, using a standardised data collection tool. Results: Fifty-seven trusts/healthcare organisations submitted data on medicines prescribed for 7915 patients: two-thirds (66%) were prescribed medication with anticholinergic properties, while just under a quarter (23%) had a medication regimen with high anticholinergic burden (total score ≥3 on the anticholinergic effect on cognition (AEC) scale). Some 16% of patients with a diagnosis of dementia or mild cognitive impairment were prescribed medication regimens with a high anticholinergic burden, compared with 35% of those without such diagnoses. A high anticholinergic burden was mostly because of combinations of commonly prescribed psychotropic medications, principally antidepressant and antipsychotic medications with individual AEC scores of 1 or 2. Conclusions: Adults under the care of older people's mental health services are commonly prescribed multiple medications for psychiatric and physical disorders; these medication regimens can have a high anticholinergic burden, often an inadvertent consequence of the co-prescription of medications with modest anticholinergic activity. Prescribers for older adults should assess the anticholinergic burden of medication regimens, assiduously check for adverse anticholinergic effects and consider alternative medications with less anticholinergic effect where indicated. The use of a scale, such as the AEC, which identifies the level of central anticholinergic activity of relevant medications, can be a helpful clinical guide.

    Quality of melatonin use in children and adolescents: findings from a UK clinical audit

    by Carol Paton, Paul Gringras, Alice Ruan, Ashley Liew, Olivia Rendora, Gaia Bove, Thomas R E Barnes

    Background Melatonin is commonly used to treat sleep disturbance in children and adolescents, although uncertainties about its optimal use remain. Objective To determine to what extent prescribing of melatonin complies with evidence-based clinical practice standards. Methods As part of a quality improvement programme, the Prescribing Observatory for Mental Health conducted a retrospective clinical audit in UK services for children and adolescents. Findings Data were submitted for 4151 children and adolescents up to 18 years of age, treated with melatonin: 3053 (74%) had a diagnosis of neurodevelopmental disorder. In 2655 (73%) of the 3651 patients prescribed melatonin to be taken regularly, the main reason was to reduce sleep latency (time taken to fall asleep). In 409 patients recently starting melatonin, a non-pharmacological intervention had already been tried in 279 (68%). The therapeutic response of patients early in treatment (n=899) and on long-term treatment (n=2353) had been assessed and quantified in 36% and 31%, respectively, while for review of side effects, the respective proportions were 46% and 43%. Planned treatment breaks were documented in 317 (13%) of those on long-term treatment. Conclusions Melatonin was predominantly prescribed for evidence-based clinical indications, but the clinical review and monitoring of this treatment fell short of best practice. Clinical implications With limited methodical review of melatonin use in their patients, clinicians will fail to garner reliable information on its risks and benefits for individual patients. The lack of such practice-based evidence may increase the risk of melatonin being inappropriately targeted or continued despite being ineffective or no longer indicated.

    Exploring the clinical factors affecting lithium dose and plasma level and the effect of brand

    by Carol Paton, Paul Bassett, Olivia Rendora, Thomas R. E. Barnes

    Background: Optimal use of lithium involves adjustment of the dose, to keep the plasma level within the narrow, recommended range. Brand-specific prescribing has long been considered critical to achieving this aim, but this is a convention based on very limited data. Objectives: To explore the effect of selected demographic and clinical factors on the relationship between lithium dose and plasma level and determine whether there is an independent effect of lithium brand. Design: Analysis of clinical audit data collected in 2023 as part of a quality improvement programme addressing the use of lithium, conducted by the Prescribing Observatory for Mental Health. Methods: Data were collected from clinical records using a bespoke proforma, submitted online and analysed using SPSS. Results: Data were submitted for 4405 patients who had been prescribed solid-dosage formulations of lithium for more than a year. Priadel® was prescribed for 3722 (84%) of these patients, Camcolit® for 112 (2.5%) and the prescription was written generically for 554 (12.5%). Compared with Priadel, where Camcolit was prescribed, the mean daily dose was 10% higher and the mean plasma lithium level was 11% higher. A multivariable analysis was conducted to explore the relationship between selected clinical variables and maintenance lithium dose. This found that in 4213 patients whose most recent plasma lithium level was between 0.3 and 1.19 mmol/L, the variables age, sex, ethnicity, psychiatric diagnosis and the severity of chronic kidney disease were independently associated with dose while the brand of lithium prescribed was not. Conclusion: Our findings replicate those of previous studies with respect to the demographic and clinical variables that can be expected to influence lithium dosage in routine clinical practice. This reinforces the need to titrate the dosage for each individual patient, to achieve and maintain the target plasma level. However, the findings suggest that the Priadel and Camcolit brands of lithium are essentially interchangeable.

    Management of medically assisted withdrawal from alcohol in acute adult mental health and specialist addictions in-patient services: UK clinical audit findings

    by Julia Sinclair, Thomas R. E. Barnes, Anne Lingford-Hughes, Colin Drummond, Ignatius Loubser, Olivia Rendora, Carol Paton

    Background: Medically assisted alcohol withdrawal (MAAW) is increasingly undertaken on acute adult psychiatric wards. Aims: Comparison of the quality of MAAW between acute adult wards and specialist addictions units in mental health services. Method: Clinical audit conducted by the Prescribing Observatory for Mental Health (POMH). Information on MAAW was collected from clinical records using a bespoke data collection tool. Results: Forty-five National Health Service (NHS) mental health trusts/healthcare organisations submitted data relating to the treatment of 908 patients undergoing MAAW on an acute adult ward or psychiatric intensive care unit (PICU) and 347 admitted to a specialist NHS addictions unit. MAAW had been overseen by an addiction specialist in 33 (4%) of the patients on an acute adult ward/PICU. A comprehensive alcohol history, measurement of breath alcohol, full screening for Wernicke's encephalopathy, use of parenteral thiamine, prescription of medications for relapse prevention (such as acamprosate) and referral for specialist continuing care of alcohol-related problems following discharge were all more commonly documented when care was provided on a specialist unit or when there was specialist addictions management on an acute ward. Conclusions: The findings suggest that the quality of care provided for medically assisted withdrawal from alcohol, including the use of evidence-based interventions, is better when clinicians with specialist addictions training are involved. This has implications for future quality improvement in the provision of MAAW in acute adult mental health settings.

    Who is prescribed valproate and how carefully is this treatment reviewed in UK mental health services? Data from a clinical audit

    by Carol Paton, Leslie Citrome, Emilio Fernandez-Egea, Olivia Rendora, Thomas R.E. Barnes

    Background: The licensed indications for valproate are narrow, yet this medication is commonly prescribed in mental health services. Objectives: To explore the target symptoms/behaviours for which valproate is prescribed and how well the efficacy and tolerability of this treatment are monitored in routine clinical practice. Design: An audit-based quality improvement (QI) programme in UK mental health services. Methods: Information on valproate prescribing was collected from clinical records using a bespoke data collection tool. Results: Sixty-four NHS mental health Trusts/healthcare organisations submitted data on valproate treatment for 5320 patients. Valproate was clearly prescribed for a licensed indication in 1995 (38%) patients, off-label in 1987 (37%) while the indication was uncertain/not available in 1338 (25%). Of the 919 patients started on valproate treatment within the past year, between a half and two-thirds had each of the relevant baseline physical health checks documented. In 539 (59%) of these patients, valproate was prescribed for an unlicensed indication; the prescription was recognised as off-label in 363 (67%), 20 (6%) of whom were documented as having had this explained to them. Of 631 patients prescribed valproate for between 3 months and a year, early on-treatment assessments of response and side effects were documented in 441 (70%) and 332 (53%), respectively. Of 4401 patients treated for more than a year, annual on-treatment reviews of clinical response and side effects were documented in 2771 (63%) and 2140 (49%), respectively. Conclusion: Our data suggest the majority of prescriptions for valproate in mental health services are not for a licensed indication. Furthermore, patients rarely receive an explanation that their valproate prescription is off-label, perhaps partly because the licensed indications are not widely understood by prescribers. Given the very limited evidence for efficacy for the off-label uses of valproate, failure to routinely conduct early on-treatment and annual reviews of the benefits and side effects of this medication may result in patients remaining on ineffective and poorly tolerated treatment by default.

    Prescribing clozapine in the UK: Quality improvement issues identified by clinical audit

    by Thomas Re Barnes, James H MacCabe, John M Kane, Oriana Delgado, Mareeha Khan, Carol Paton

    Introduction: The Prescribing Observatory for Mental Health initiated a quality improvement (QI) programme on clozapine use in UK mental health services. Methods: Clinical audits conducted in 2019 and 2021. Results: Sixty-three participating NHS Trusts/healthcare organisations in 2019, and 61 in 2021, submitted treatment data for 6948 and 8155 patients, respectively. In both audits, high-dose and/or combined antipsychotic medications had been prescribed immediately before initiating clozapine in over a quarter of patients recently started on clozapine. In patients who were tobacco smokers and recently discharged from a smoke-free ward, the impact of the potential change in smoking status had been considered in the care plans of just under one-third in 2019 and just over a half in 2021. For community patients, their Summary Care Records (SCRs) included their clozapine prescriptions in 58% of cases in 2019 and 72% in 2021. Conclusions: Three QI issues were identified. (1) Antipsychotic regimens with limited evidence for efficacy in treatment-resistant schizophrenia were prescribed for over a quarter of cases before starting clozapine. Use of such strategies may delay clozapine treatment, potentially reducing the likelihood of a therapeutic response. (2) While anticipation of the consequences of a change in smoking status on plasma clozapine concentration following discharge from hospital showed improvement over time, even in 2021 it was not evident for nearly a half of relevant cases. (3) While inclusion of clozapine in the SCR also improved over time, even in 2021 it was missing for more than a quarter of community patients.

    Plus ça change? Switching lithium preparations

    by David A. Cousins, Thomas R. E. Barnes, Allan H. Young, Oriana Delgado, Carol Paton

    Aims and method: A supply disruption alert in 2020, now rescinded, notified UK prescribers of the planned discontinuation of Priadel® (lithium carbonate) tablets. This service evaluation explored lithium dose and plasma levels before and after the switching of lithium brands, in order to determine the interchangeability of different brands of lithium from a pharmacokinetic perspective.Results: Data on the treatment of 37 patients switched from Priadel® tablets were analysed. Switching to Camcolit® controlled-release tablets at the same dose did not result in meaningful differences in plasma lithium levels. Dose adjustment and known or suspected poor medication adherence were associated with greater variability in plasma lithium levels on switching brands.Clinical implications: For comparable pre- and post-switch doses in adherent patients, the most common brands of lithium carbonate appear to produce similar plasma lithium levels. British National Formulary guidance relating to switching lithium brands may be unnecessarily complex.

    Can the use of long-acting injectable antipsychotic preparations be increased in routine clinical practice and the benefits realised?

    by Carol Paton, Chike I. Okocha, Maxine X. Patel

    Background: The use of continuing antipsychotic medication is an established evidence-based strategy for preventing relapse in people with schizophrenia, but medication adherence is known to be suboptimal. Covert non-adherence can be eliminated by the use of long-acting injectable (LAI) formulations. We sought to (1) raise awareness among clinicians of the potential benefits of LAI antipsychotic formulations, (2) increase use of these formulations for the treatment of schizophrenia in routine clinical practice and thereby (3) reduce the number of relapses requiring hospitalisation in patients with schizophrenia under our care. Method: Educational initiatives, promotion of reflective practice and patient-specific reminders were used to prompt increased use of LAI antipsychotic medication for patients with schizophrenia. Data relating to the use of these medications and the number of acute admissions for schizophrenia spectrum disorders (F20-29, ICD-10) over time were extracted from existing clinical information systems. Results: Over the 3-year time frame of our local initiative, the use of LAI antipsychotic preparations increased by 11%, the number of acute admissions for schizophrenia/schizoaffective disorder (F20 and F25) decreased by 26% and the number of acute bed days occupied by patients with these diagnoses decreased by 8%. The number of admissions for other psychosis diagnoses (F21-24 and F28-29) did not show the same pattern of improvement. Conclusion: In our health care organisation, raising clinicians’ awareness of the evidence base relating to the potentially favourable benefit–risk balance for LAI antipsychotic medication compared with oral formulations resulted in more use of the former. There were accompanying reductions in acute admissions and occupied bed days for patients with schizophrenia.

    Prescribing antipsychotic medication for adults with intellectual disability: shared responsibilities between mental health services and primary care

    by Carol Paton, Ashok Roy, Kiran Purandare, Olivia Rendora, Thomas R. E. Barnes

    Aims and method We conducted a secondary analysis of data from a Prescribing Observatory for Mental Health audit to assess the quality of requests from intellectual disability services to primary care for repeat prescriptions of antipsychotic medication. Results Forty-six National Health Service Trusts submitted treatment data on 977 adults with intellectual disability, receiving antipsychotic medication for more than a year, for whom prescribing responsibility had been transferred to primary care. Therapeutic effects had been monitored in the past 6 months in 80% of cases with a documented communication indicating which service was responsible for this and 72% of those with no such communication. The respective proportions were 69% and 42% for side-effect monitoring, and 79% and 30% for considering reducing/stopping antipsychotic medication. Clinical implications Where continuing antipsychotic medication is prescribed in primary care for people with intellectual disability, lack of guidance from secondary care regarding responsibilities for monitoring its effectiveness may be associated with inadequate review.
