The impact of providing care for physical health in severe mental illness on informal carers: a qualitative study.

BACKGROUND: People with severe mental illness (SMI) such as schizophrenia and bipolar disorder are at a substantially higher risk of premature death in that they die between 10 and 20 years earlier than the general population. Cardiovascular disease (CVD) and diabetes are the main potentially avoidable contributors to early death. Research that explores the experiences of people with SMI highlights their struggles in engaging with health professionals and accessing effective and timely interventions for physical health conditions. A consequence of such struggles to navigate and access physical healthcare results in many people with SMI relying heavily on support provided by informal carers (e.g., family members, close friends). Despite this, the experiences of informal carers, and the roles they undertake in relation to supporting the physical health and psychotropic medication use of people with SMI, remains under-researched. AIMS: To explore the impacts of providing care for physical health in severe mental illness on informal carers. METHOD: Thematic analysis of semi-structured interviews with eight informal carers of people with SMI in United Kingdom (UK) national health services. RESULTS: Informal carers played an active part in the management of the patient's conditions and shared their illness experience. Involvement of informal carers was both emotional and practical and informal carers' own lives were affected in ways that were sometimes deeply profound. Informal carers were involved in both 'looking after' the patient from the perspective of doing practical tasks such as collecting dispensed medication from a community pharmacy (caring for) and managing feelings and emotions (caring about). CONCLUSIONS: Providing care for the physical health of someone with SMI can be understood as having two dimensions - 'caring for' and 'caring about'. The findings suggest a bidirectional relationship between these two dimensions, and both have a cost for the informal carer. With appropriate support informal carers could be more actively involved at all stages of care without increasing their burden. This should be with an awareness that carers may minimise the information they share about their own needs and impacts of their role to spare the person they care and themselves any distress.

What really is nontokenistic fully inclusive patient and public involvement/engagement in research?

Patient and public involvement and engagement (PPIE) is critically important in healthcare research. A useful starting point for researchers to understand the scope of PPIE is to review the definition from the National Institute for Health and Care Research (NIHR) as, 'research being carried out "with" or "by" members of the public rather than "to", "about" or "for" them'. PPIE does not refer to participation in research, but to actively shaping its direction. The 'Effectiveness of a decision support tool to optimise community-based tailored management of sleep for people living with dementia or mild cognitive impairment (TIMES)' study is funded through the NIHR programme grant for applied research. TIMES has thoroughly embraced PPIE by ensuring the person's voice is heard, understood, and valued. This editorial showcases how the TIMES project maximised inclusivity, and we share our experiences and top tips for other researchers. We base our reflections on the six key UK standards for public involvement; Inclusive Opportunities, Working Together, Support and Learning, Communications, Impact and Governance. We present our work, which had been co-led by our PPIE leads, academics and partners including, together in dementia everyday, Innovations in Dementia, The UK Network of Dementia Voices (Dementia Engagement & Empowerment Project) and Liverpool Chinese Wellbeing. We have a Lived Experience Advisory Forum on Sleep, which includes people with dementia, family carers, representatives of the South Asian Community and the Chinese community.

Community pharmacists' perceptions on managing people with oral health problems-A prioritisation survey.

BACKGROUND: Alternative sources of oral health information are likely to be of benefit to the public, particularly where access to dental services is limited. There is evidence that community pharmacists are willing to advocate for oral health, but it is unclear what is needed to develop this role. OBJECTIVES: The aims of this study were to obtain the views of community pharmacy staff on the frequency and type of oral health conditions they encounter challenges in management and training/research priorities. METHODS: An anonymous online survey targeted pharmacy staff and elicited quantitative data related to the types and frequencies of oral health conditions experienced. Participants were stratified by age, gender, ethnicity, experience and setting. Free text responses allowed participants to detail challenging aspects of patient management, their priorities for service development and future research. Reflexive thematic analysis of free text responses identified key themes. RESULTS: Oral/facial pain and swelling were seen weekly by most respondents, and daily by 28.8%. Other commonly presenting conditions were ulcers, dry-mouth, thrush and denture issues. Challenges in managing oral health conditions included: access to NHS dentistry, awareness of referral pathways, examination/diagnosis and understanding 'Red Flags'. CONCLUSION: Acute and chronic oral health conditions commonly present to community pharmacists who lack necessary knowledge/training, which may result in missing 'red flag' symptoms for oral cancer or acute facial swellings which can be life threatening. There is a need to support pharmacists, who are willing to act as oral health advocates, in recognition, prevention and onward referral for oral diseases.

What are patients' experiences of discontinuing clozapine and how does this impact their views on subsequent treatment?

BACKGROUND: Discontinuing what is considered the most effective treatment for treatment-resistant schizophrenia may precipitate feelings of failure or a relapse of illness. Clozapine treatment is discontinued for a variety of reasons, including non-adherence, intolerance, or lack of efficacy. Patients' experiences of discontinuing the "best" treatment and the impact on perceptions of subsequent antipsychotic treatment are important in developing an understanding of the factors affecting people's treatment choices. This study is the first of its type, seeking to explore people's perspectives on clozapine discontinuation. METHOD: Semi-structured interviews with sixteen patients who had received clozapine and discontinued treatment-thirteen males and three females, age range: thirty-two to seventy-eight years old-were audio-recorded and transcribed. A modified inductive approach to analysis, based on grounded theory, was taken to identify commonalities and differences in patients' perceptions. RESULTS: The three main themes identified from participants' experiences were: (1) positive and negative effects of treatment; (2) feelings of agency, being the capacity to make decisions about treatment and act independently; (3) choice of treatment in the future. Participants exhibited agency in making choices about medication, including risking relapse, while attempting self-management of medication effects. Different participants perceived the same side effect as beneficial or intolerable. Variation in subsequent treatment choices was reported, with some participants favouring depot (long-acting) injections. A participant was frightened when not told about clozapine's side effects, which led to the participant not being engaged in future treatment decisions. Others, despite suffering serious adverse effects, retained positive perceptions of clozapine; they experienced despair at finding an effective alternative. CONCLUSIONS: Experiences with clozapine discontinuation evoked powerful emotions and resulted in clozapine being the benchmark for other treatments. Knowledge, agency, and being in control were important to participants in relation to treatment. Personal perceptions of treatments or beliefs about illness could lead to non-adherence. People value the clinician listening to their experiences to better understand their perspective, enabling concerns about medication to be addressed through true shared decision making.

Deprescribing psychotropic medicines for behaviours that challenge in people with intellectual disabilities: a systematic review.

BACKGROUND: Clear evidence of overprescribing of psychotropic medicines to manage behaviours that challenges in people with intellectual disabilities has led to national programmes within the U.K. such as NHS England's STOMP to address this. The focus of the intervention in our review was deprescribing of psychotropic medicines in children and adults with intellectual disabilities. Mental health symptomatology and quality of life were main outcomes. METHODS: We reviewed the evidence using databases Medline, Embase, PsycINFO, Web of Science, CINAHL and Open Grey with an initial cut-off date of 22nd August 2020 and an update on 14th March 2022. The first reviewer (DA) extracted data using a bespoke form and appraised study quality using CASP and Murad tools. The second reviewer (CS) independently assessed a random 20% of papers. RESULTS: Database searching identified 8675 records with 54 studies included in the final analysis. The narrative synthesis suggests that psychotropic medicines can sometimes be deprescribed. Positive and negative consequences were reported. Positive effects on behaviour, mental and physical health were associated with an interdisciplinary model. CONCLUSIONS: This is the first systematic review of the effects of deprescribing psychotropic medicines in people with intellectual disabilities which is not limited to antipsychotics. Main risks of bias were underpowered studies, poor recruitment processes, not accounting for other concurrent interventions and short follow up periods. Further research is needed to understand how to address the negative effects of deprescribing interventions. TRIAL REGISTRATION: The protocol was registered with PROSPERO (registration number CRD42019158079).

Higher anticholinergic burden from medications is associated with significant increase in markers of inflammation in the EPIC-Norfolk prospective population-based cohort study.

BACKGROUND: Higher medication anticholinergic burden is associated with increased risk of cardiovascular disease and cognitive decline. A mechanistic pathway has not been established. We aimed to determine whether inflammation may mediate these associations. METHODS: Participants were drawn from the European Prospective Investigation into Cancer, Norfolk cohort (40-79 years at baseline). Anticholinergic burden score (ACB) was calculated at first (1HC) (1993/97) and second (2HC) (1998/2000) health checks. Fibrinogen and C-reactive protein (CRP) were measured during 1HC and tumour necrosis factor alpha (TNF-α) and interleukin 6 (IL-6) during 2HC. Cross-sectional associations between ACB and inflammatory markers were examined for both health checks. Prospective associations were also examined between 1HC ACB and 2HC inflammatory markers. Models were adjusted for age, sex, lifestyle factors, comorbidities and medications. RESULTS: In total, 17 678 and 22 051 participants were included in cross-sectional analyses for CRP, and fibrinogen, respectively. Furthermore, 5101 participants with data on TNF-α and IL-6 were included in the prospective analyses. Cross-sectionally, compared to ACB = 0, ACB ≥ 4 was associated with higher fibrinogen, beta (95% confidence interval) = 0.134 g/L (0.070, 0.199), CRP 1.175 mg/L (0.715, 1.634), IL-6 0.593 pg/mL (0.254, 0.932) and TNF-α 0.137 pg/mL (0.033, 0.241). In addition, a point increase in ACB was associated with higher levels of all markers. Prospectively, compared to ACB = 0, ACB ≥ 4 was associated with higher IL-6(pg/mL) of 0.019 (-0.323, 0.361) and TNF-α (pg/mL) of 0.202% (0.81, 0.323). A unit increase in ACB was associated with a significantly higher TNF-α and IL-6. CONCLUSION: Higher ACB was associated with higher inflammatory markers. Inflammation may mediate the relationship between anticholinergic medications and adverse outcomes.

A novel Artificial Intelligence-based tool to assess anticholinergic burden: a survey.

BACKGROUND: many medications possess anticholinergic activity. Their use is associated with a number of serious adverse effects including cognitive effects. The cumulative anticholinergic effect of medications as assessed by tools such as the anticholinergic burden scale (AchB) can identify people particularly at risk of anticholinergic side-effects. Currently, >20 tools are available for clinicians to use, but there is no consensus on the most appropriate tool. METHODS: a newly created online tool-International Anticholinergic Cognitive Burden Tool (IACT)-based on natural language processing and chemical structure analysis, was developed and made available for clinicians to test its functions. We carried out a survey (between 8th of February and 31st of March 2021) to assess the overall need for an assessment tool as well as the usability of the IACT. RESULTS: a total of 110 responses were received from different countries and practitioners' groups. The majority of the participants (86.11%) stated they would use a tool for AchB assessment if available and when they were asked to rate the IACT against other tools, amongst 34 responders, 20.59% rated it better and 8.82% rated it significantly better, 44.12% rated it neither better, nor worse, 14.71% rated it worse and 11.76% somewhat worse. CONCLUSION: there is a need for an anticholinergic burden calculator to assess the anticholinergicity of medications. Tools such as the IACT potentially could meet this demand due to its ability to assign scores to current and new medications appearing on the market based both on their chemical structure and reported adverse pharmacological effects.

Medication management in Minority, Asian and Black ethnic older people in the United Kingdom: A mixed-studies systematic review.

WHAT IS NEW AND OBJECTIVES: Older people from ethnic minorities experience the intersectionality of age and ethnicity in relation to complex medication management and polypharmacy. Minority ethnic groups in the United Kingdom are at risk of poor medication management because factors such as cultural beliefs, language barriers, lack of knowledge of how the healthcare system works may affect their ability to safely manage their medications. The aim of this systematic review was to review the literature focussing on medication management in the older population amongst ethnic minority communities in United Kingdom. METHODS: The review was conducted and reported according to methods in the Cochrane Handbook and in the PRISMA 2020 statement using databases such as EMBASE, ASSIA, MEDLINE, PsychINFO and others. Studies conducted in the United Kingdom on individuals over 60 years of age and from a minority ethnic background were included. A thematic analysis was used to synthesize the results. RESULTS AND DISCUSSION: Nine studies (eight from initial searches, one from a search update in 2021) met the inclusion criteria. Three main themes were identified: misbeliefs around medications, poor health literacy, communication and education as possible intervention to improve medication management. Misbeliefs around long-term illnesses exert a negative impact on medication management. Poor health literacy around medications influences patients' adherence to treatments. Poor communication is perceived as barrier to successful medication management. Despite extensive searching, the team identified a limited number of studies and a lack of intersectional studies focussing on minority ethnic groups and the older population. WHAT IS NEW AND CONCLUSION: Our findings suggest tailored education as a possible intervention to improve medication management amongst these minority groups. Future research should look at recruiting participants from specific ethnic groups and from rural as well as urban areas to explore how medication management operates in different areas of the United Kingdom.

Cognitive decline associated with anticholinergics, benzodiazepines and Z-drugs: Findings from The Irish Longitudinal Study on Ageing (TILDA).

AIMS: To estimate the association between patterns of anticholinergic, benzodiazepine and Z-drug medication use and change in cognitive function in middle-aged and older adults. METHODS: This prospective cohort study used data from the first three waves of The Irish Longitudinal Study on Ageing (TILDA), including community-dwelling adults aged ≥50 years followed for up to 4 years (n = 7027). Cognitive function was assessed using the Mini Mental State Examination, animal naming test and word recall tests. Regular medication use was self-reported at baseline and follow-up interviews at 2 and 4 years. Pharmacy dispensing claims for a subset (n = 2905) allowed assessment of medication use between interviews and cumulative dosage. Medication use at consecutive waves of TILDA was analysed in relation to change in cognitive function between waves. RESULTS: Strongly anticholinergic medications (Anticholinergic Cognitive Burden scale 3), benzodiazepines and Z-drugs were reported by 7.3%, 5.8% and 5.1% of participants, respectively, at any time during the study. Adjusting for potential confounders, new anticholinergic use between interviews was associated with change in recall score (-1.09, 95% confidence interval -1.64, -0.53) over 2 years compared to non-use, but not with MMSE (0.07; 95% CI -0.21, 0.34) or animal naming (-0.70; 95% CI -1.43, 0.03). The pharmacy claims analysis was consistent with this finding. Other hypothesised associations were not supported. CONCLUSIONS: Except for new use of anticholinergic medications, no other findings supported a risk of cognitive decline over 2-year periods in this middle-aged and older cohort. Patients and prescribers should weigh this potential risk against potential benefits of commencing anticholinergic medications.

The experiences of the caring dyad: (Un)articulated realities of living with cardiometabolic risk, metabolic syndrome and related diseases in severe mental illness.

BACKGROUND: Informal carers play an important role in the care of patients with mental illness. Little is known of the relationship experience of the patient and their informal carer (caring dyad) as the context for the intersection between physical and mental health. AIM: This study aimed to explore the impact of comorbid cardiometabolic risk (CMR), metabolic syndrome (MetS) and related diseases and severe mental illness (SMI) on the caring dyad. DESIGN: Between October 2018 and March 2020, we conducted 11 in-depth semi-structured interviews across 6 adult caring dyads, interviewing each individual separately. SETTING: Dyads were recruited within the United Kingdom; informal carers were nominated by the patient as a person who provided a significant amount of support. VARIABLE BEING STUDIED: Participants were asked about the impacts of illness and caring on daily life. DATA ANALYSIS: Data were analysed at the dyad level using thematic analysis, comparing and contrasting responses from each individual. RESULTS: Themes were identified: enhanced closeness, dissonance and balance within the caring dyad. DISCUSSION AND CONCLUSIONS: This study uses a particular population of patients with comorbid CMR factors, MetS and related diseases and SMI and their informal carers to explore the relevance and utility of caring dyads as an analytical framework to inform practice and policy. Future interventions should consider factors impacting on dyadic relationships to formulate effective and sustainable dyadic care and treatment to improve health outcomes for both patients with SMI and their informal carers. PATIENT/PUBLIC INVOLVEMENT: In this study, patients and informal carers were participants. Topic guides were piloted with a patient and informal carer.

Adverse effects of Z-drugs for sleep disturbance in people living with dementia: a population-based cohort study.

BACKGROUND: Sleep disturbance is common in dementia and often treated with Z-drugs (zopiclone, zaleplon, and zolpidem). While some observational studies suggest that Z-drugs are associated with adverse events such as falls and fracture risks in older people, this has not been studied in dementia. METHODS: We used data from 27,090 patients diagnosed with dementia between January 2000 and March 2016 from the Clinical Practice Research Datalink linked to Hospital Episodes Statistics data in England. We compared adverse events for 3532 patients newly prescribed Z-drugs by time-varying dosage to (1) 1833 non-sedative-users with sleep disturbance; (2) 10,214 non-sedative-users with proximal GP consultation matched on age, sex, and antipsychotic use; and (3) 5172 patients newly prescribed benzodiazepines. We defined higher dose Z-drugs and benzodiazepines as prescriptions equivalent to ≥ 7.5 mg zopiclone or > 5 mg diazepam daily. Cox regression was used to estimate hazard ratios (HRs) for incident fracture, hip fracture, fall, mortality, acute bacterial infection, ischaemic stroke/transient ischaemic attack, and venous thromboembolism over a 2-year follow-up, adjusted for demographic- and health-related covariates. RESULTS: The mean (SD) age of patients was 83 (7.7) years, and 16,802 (62%) were women. Of 3532 patients prescribed Z-drugs, 584 (17%) were initiated at higher doses. For patients prescribed higher dose Z-drugs relative to non-users with sleep disturbance, the HRs (95% confidence interval) for fractures, hip fractures, falls, and ischaemic stroke were 1.67 (1.13-2.46), 1.96 (1.16-3.31), 1.33 (1.06-1.66), and 1.88 (1.14-3.10), respectively. We observed similar associations when compared to non-sedative-users with proximal GP consultation. Minimal or inconsistent excess risks were observed at ≤ 3.75 mg zopiclone or equivalent daily, and for mortality, infection, and venous thromboembolism. We observed no differences in adverse events for Z-drugs compared to benzodiazepines, except lower mortality rates with Z-drugs (HR [95% confidence interval] of 0.73 [0.64-0.83]). CONCLUSIONS: Higher dose Z-drug use in dementia is associated with increased fracture and stroke risks, similar or greater to that for higher dose benzodiazepines. Higher dose Z-drugs should be avoided, if possible, in people living with dementia, and non-pharmacological alternatives preferentially considered. Prescriptions for higher dose Z-drugs in dementia should be regularly reviewed. TRIAL REGISTRATION: ENCePP e-register of studies, EUPAS18006.

Anticholinergic drugs and incident dementia, mild cognitive impairment and cognitive decline: a meta-analysis.

BACKGROUND: the long-term effect of the use of drugs with anticholinergic activity on cognitive function remains unclear. METHODS: we conducted a systematic review and meta-analysis of the relationship between anticholinergic drugs and risk of dementia, mild cognitive impairment (MCI) and cognitive decline in the older population. We identified studies published between January 2002 and April 2018 with ≥12 weeks follow-up between strongly anticholinergic drug exposure and the study outcome measurement. We pooled adjusted odds ratios (OR) for studies reporting any, and at least short-term (90+ days) or long-term (365+ days) anticholinergic use for dementia and MCI outcomes, and standardised mean differences (SMD) in global cognition test scores for cognitive decline outcomes. Statistical heterogeneity was measured using the I2 statistic and risk of bias using ROBINS-I. RESULTS: twenty-six studies (including 621,548 participants) met our inclusion criteria. 'Any' anticholinergic use was associated with incident dementia (OR 1.20, 95% confidence interval [CI] 1.09-1.32, I2 = 86%). Short-term and long-term use were also associated with incident dementia (OR 1.23, 95% CI 1.17-1.29, I2 = 2%; and OR 1.50, 95% CI 1.22-1.85, I2 = 90%). 'Any' anticholinergic use was associated with cognitive decline (SMD 0.15; 95% CI 0.09-0.21, I2 = 3%) but showed no statistically significant difference for MCI (OR 1.24, 95% CI 0.97-1.59, I2 = 0%). CONCLUSIONS: anticholinergic drug use is associated with increased dementia incidence and cognitive decline in observational studies. However, a causal link cannot yet be inferred, as studies were observational with considerable risk of bias. Stronger evidence from high-quality studies is needed to guide the management of long-term use.

Towards an understanding of the burdens of medication management affecting older people: the MEMORABLE realist synthesis.

BACKGROUND: More older people are living in the community with multiple diagnoses and medications. Managing multiple medications produces issues of unrivalled complexity for those involved. Despite increasing literature on the subject, gaps remain in understanding how, why and for whom complex medication management works, and therefore how best to improve practice and outcomes. MEMORABLE, MEdication Management in Older people: Realist Approaches Based on Literature and Evaluation, aimed to address these gaps. METHODS: MEMORABLE used realism to understand causal paths within medication management. Informed by RAMESES (Realist And Meta-narrative Evidence Synthesis: and Evolving Standards) guidelines, MEMORABLE involved three overlapping work packages: 1) Realist Review of the literature (24 articles on medication management exploring causality); 2) Realist Evaluation (50 realist-informed interviews with older people, family carers and health and care practitioners, explaining their experiences); and 3) data synthesis and theorising from 1) and 2). RESULTS: Medication management was viewed from the perspective of 'implementation' and structured into five stages: identifying a problem (Stage 1), getting a diagnosis and/or medications (Stage 2), starting, changing or stopping medications (Stage 3), continuing to take medications (Stage 4), and reviewing/reconciling medications (Stage 5). Three individual stages (1, 3 and 4) are conducted by the older person sometimes with family carer support when they balance routines, coping and risk. Stages 2 and 5 are interpersonal where the older person works with a practitioner-prescriber-reviewer, perhaps with carer involvement. Applying Normalisation Process Theory, four steps were identified within each stage: 1) sense making: information, clarification; 2) action: shared-decision-making; 3) reflection/monitoring; and 4) enduring relationships, based on collaboration and mutual trust. In a detailed analysis of Stage 5: Reviewing/reconciling medications, adopting the lens of 'burden', MEMORABLE identified five burdens amenable to mitigation: ambiguity, concealment, unfamiliarity, fragmentation and exclusion. Two initial improvement propositions were identified for further research: a risk screening tool and individualised information. CONCLUSIONS: Older people and family carers often find medication management challenging and burdensome particularly for complex regimens. Practitioners need to be aware of this potential challenge, and work with older people and their carers to minimise the burden associated with medication management.

Increasing prevalence of anticholinergic medication use in older people in England over 20 years: cognitive function and ageing study I and II.

BACKGROUND: Anticholinergic medication use is linked with increased cognitive decline, dementia, falls and mortality, and their use should be limited in older people. Here we estimate the prevalence of anticholinergic use in England's older population in 1991 and 2011, and describe changes in use by participant's age, sex, cognition and disability. METHODS: We compared data from participants aged 65+ years from the Cognitive Function and Ageing Studies (CFAS I and II), collected during 1990-1993 (N = 7635) and 2008-2011 (N = 7762). We estimated the prevalence of potent anticholinergic use (Anticholinergic Cognitive Burden [ACB] score = 3) and average anticholinergic burden (sum of ACB scores), using inverse probability weights standardised to the 2011 UK population. These were stratified by age, sex, Mini-Mental State Examination score, and activities of daily living (ADL) or instrumental ADL (IADL) disability. RESULTS: Prevalence of potent anticholinergic use increased from 5.7% (95% Confidence Interval [CI] 5.2-6.3%) of the older population in 1990-93 to 9.9% (9.3-10.7%) in 2008-11, adjusted odds ratio of 1.90 (95% CI 1.67-2.16). People with clinically significant cognitive impairment (MMSE [Mini Mental State Examination] 21 or less) were the heaviest users of potent anticholinergics in CFAS II (16.5% [95% CI 12.0-22.3%]). Large increases in the prevalence of the use medication with 'any' anticholinergic activity were seen in older people with clinically significant cognitive impairment (53.3% in CFAS I to 71.5% in CFAS II). CONCLUSIONS: Use of potent anticholinergic medications nearly doubled in England's older population over 20 years with some of the greatest increases amongst those particularly vulnerable to anticholinergic side-effects.

MEDREV (pharmacy-health psychology intervention in people living with dementia with behaviour that challenges): the feasibility of measuring clinical outcomes and costs of the intervention.

BACKGROUND: People living with dementia in care homes frequently exhibit "behaviour that challenges". Anti-psychotics are used to treat such behaviour, but are associated with significant morbidity. This study researched the feasibility of conducting a trial of a full clinical medication review for care home residents with behaviour that challenges, combined with staff training. This paper focusses on the feasibility of measuring clinical outcomes and intervention costs. METHODS: People living with moderate to severe dementia, receiving psychotropics for behaviour that challenges, in care homes were recruited for a medication review by a specialist pharmacist. Care home and primary care staff received training on the management of challenging behaviour. Data were collected at 8 weeks, and 3 and 6 months. Measures were Neuropsychiatric Inventory-Nursing Home version (NPI-NH), cognition (sMMSE), quality of life (EQ-5D-5 L/DEMQoL) and costs (Client Services Receipt Inventory). Response rates, for clinical, quality of life and health economic measures, including the levels of resource-use associated with the medication review and other non-intervention costs were calculated. RESULTS: Twenty-nine of 34 participants recruited received a medication review. It was feasible to measure the effects of the complex intervention on the management of behaviour that challenges with the NPI-NH. There was valid NPI-NH data at each time point (response rate = 100%). The sMMSE response rate was 18.2%. Levels of resource-use associated with the medication review were estimated for all 29 participants who received a medication review. Good response levels were achieved for other non-intervention costs (100% completion rate), and the EQ-5D-5 L and DEMQoL (≥88% at each of the time points where data was collected). CONCLUSIONS: It is feasible to measure the clinical and cost effectiveness of a complex intervention for behaviour that challenges using the NPI-NH and quality of life measures. TRIAL REGISTRATION: ISRCTN58330068. Retrospectively registered, 15 October 2017.

Recruiting people with severe mental illness through community pharmacies: real-world experiences from a UK study.

BACKGROUND: Proxy recruitment of patient participants through community pharmacies may be a valuable strategy to maximise participation. This paper focuses on the feasibility of such a recruitment strategy for research involving people who experience severe mental illness. METHODS: Fifty-three community pharmacies, including 50 'Research Ready' pharmacies, were asked to recruit people with severe mental illness for participation in research. Pharmacists were asked to provide participant information to anyone presenting a prescription meeting specific criteria. RESULTS: Thirteen recruitment sites (25%) (from 4 distinct organisations) were approved to recruit patient participants. Eighty-five percent (n = 11) failed to recruit any potential participants. CONCLUSIONS: Proxy recruitment of people with severe mental illness through community pharmacies was challenging with challenges in both pharmacy- and participant-recruitment. Further investigation into supporting community pharmacists' engagement with recruiting patients with SMI as research participants is required.

History of Benzodiazepine Prescriptions and Risk of Dementia: Possible Bias Due to Prevalent Users and Covariate Measurement Timing in a Nested Case-Control Study.

Previous estimates of whether long-term exposure to benzodiazepines increases dementia risk are conflicting and are compromised by the difficulty of controlling for confounders and by reverse causation. We investigated how estimates for the association between benzodiazepine use and later dementia incidence varied based on study design choices, using a case-control study nested within the United Kingdom's Clinical Practice Research Datalink. A total of 40,770 dementia cases diagnosed between April 2006 and July 2015 were matched on age, sex, available data history, and deprivation to 283,933 control subjects. Benzodiazepines and Z-drug prescriptions were ascertained in a drug-exposure period 4-20 years before dementia diagnosis. Estimates varied with the inclusion of new or prevalent users, with the timing of covariate ascertainment, and with varying time between exposure and outcome. There was no association between any new prescription of benzodiazepines and dementia (adjusted odds ratio (OR) = 1.03, 95% confidence interval (CI): 1.00, 1.07), whereas an inverse association was observed among prevalent users (adjusted OR = 0.91, 95% CI: 0.87, 0.95), although this was likely induced by unintentional adjustment for colliders. By considering the choice of confounders and timing of exposure and covariate measurement, our findings overall are consistent with no causal effect of benzodiazepines or Z-drugs on dementia incidence.

A mixed methods analysis of clozapine errors reported to the National Reporting and Learning System.

PURPOSE: To review and analyse medication errors related to clozapine, an atypical antipsychotic, that were reported to the National Reporting and Learning System (NRLS). METHODS: Following extraction of one year of clozapine related errors from the NRLS, a qualitative analysis (thematic analysis and re-classification) and quantitative analysis was performed. An incident was considered a clozapine error if there was a failure in its medication process (i.e. an error in the prescribing, dispensing, preparing, administering, monitoring or advising of clozapine). RESULTS: "Issues with stock/supply/ordering" was the most common theme derived from the qualitative thematic analysis (n = 338), followed by wrong dose/strength/frequency (n = 221) and medication omissions (n = 202). Most errors occurred in the "administration/supply" medication stage. Over half of reported clozapine incidents involved people 26 to 55 years old (n = 830) and 82% of errors were reported by mental health services (n = 1270). Only 1.5% of reports were classed as moderate/severe harm. CONCLUSION: Issues with availability, stock, and supply were found to be the most common causes. This usually entailed a lack of stock to fulfil a patient's dose/supply. Such incidents could potentially be reduced by improved management of the supply process, and liaison between pharmacy and clinical staff. The implementation of emergency drug cupboards at the discretion of an on-call pharmacist may prove to be a preventative measure for such errors. Despite the potential adverse effects associated with clozapine, very few incidents led to moderate/severe harm. Encouragement of NRLS reporting is recommended for incidents of all degrees of harm.

Anticholinergic and benzodiazepine medication use and risk of incident dementia: a UK cohort study.

BACKGROUND: Studies suggest that anticholinergic medication or benzodiazepine use could increase dementia risk. We tested this hypothesis using data from a UK cohort study. METHODS: We used data from the baseline (Y0), 2-year (Y2) and 10-year (Y10) waves of the Medical Research Council Cognitive Function and Ageing Study. Participants without dementia at Y2 were included (n = 8216). Use of benzodiazepines (including nonbenzodiazepine Z-drugs), anticholinergics with score 3 (ACB3) and anticholinergics with score 1 or 2 (ACB12) according to the Anticholinergic Cognitive Burden scale were coded as ever use (use at Y0 or Y2), recurrent use (Y0 and Y2), new use (Y2, but not Y0) or discontinued use (Y0, but not Y2). The outcome was incident dementia by Y10. Incidence rate ratios (IRR) were estimated using Poisson regression adjusted for potential confounders. Pre-planned subgroup analyses were conducted by age, sex and Y2 Mini-Mental State Examination (MMSE) score. RESULTS: Dementia incidence was 9.3% (N = 220 cases) between Y2 and Y10. The adjusted IRRs (95%CI) of developing dementia were 1.06 (0.72, 1.60), 1.28 (0.82, 2.00) and 0.89 (0.68, 1.17) for benzodiazepines, ACB3 and ACB12 ever-users compared with non-users. For recurrent users the respective IRRs were 1.30 (0.79, 2.14), 1.68 (1.00, 2.82) and 0.95 (0.71, 1.28). ACB3 ever-use was associated with dementia among those with Y2 MMSE> 25 (IRR = 2.28 [1.32-3.92]), but not if Y2 MMSE≤25 (IRR = 0.94 [0.51-1.73]). CONCLUSIONS: Neither benzodiazepines nor ACB12 medications were associated with dementia. Recurrent use of ACB3 anticholinergics was associated with dementia, particularly in those with good baseline cognitive function. The long-term prescribing of anticholinergics should be avoided in older people.

Second-generation antipsychotic long-acting injections in bipolar disorder: Systematic review and meta-analysis.

BACKGROUND: Non-adherence is a significant problem in bipolar disorder. Second-generation antipsychotics (SGA) long-acting injections (LAIs) may improve adherence in bipolar disorder and may prevent relapses. However, the evidence is limited and conflicting. OBJECTIVE: The objective of this study was to evaluate efficacy and safety of SGA LAIs in bipolar disorder. METHOD: Systematic review and meta-analysis of randomised controlled trials (RCTs) (≥6 months duration) investigating safety and efficacy of SGA LAIs for bipolar disorder. We searched Pubmed, Embase, CINAHL, Cochrane, PsycINFO, LiLACS, www.clinicaltrials.gov up to October 2016. We also contacted the manufacturers of SGA LAIs. Primary efficacy and safety outcomes were relapse rate and all-cause discontinuation respectively. RESULTS: Total of seven RCTs (n = 1192) were included. SGA LAIs show superiority over placebo for study-defined relapse rate (RR = 0.58, 95% CI = 0.49-0.68, P < 0.00001) and all-cause discontinuation (RR = 0.72, 95% CI = 0.64-0.82, P < 0.00001). However, no significant difference was found between SGA LAIs and oral active control for relapse rate (RR = 0.92, P = 0.79) and all-cause discontinuation (RR = 1.2, P = 0.31). In terms of secondary outcomes, SGA LAIs performed better than placebo in relapse to mania/hypomania, young mania rating scales (YMRS), clinical global impression-severity (CGI-S), montgomery-asberg depression rating scale (MADRS). There was no significant difference between SGA LAIs and oral active control regarding relapse to mania/hypomania, YMRS, CGI-S, extra-pyramidal side effects (EPSEs), weight gain. However, the active control performed better than SGA LAIs in relapse to depression, MADRS, and prolactin-related AEs. CONCLUSIONS: Current evidence is very limited to support the use of SGA LAIs (compared to oral medication) in bipolar disorder. Further high-quality studies, particularly comparing SGA LAIs with active control, are warranted.
