Tracking the 3-year trajectory of referrals to an early psychosis intervention service.

AIM: To review the baseline and clinical characteristics of patients referred to a New Zealand Early Psychosis Intervention (EPI) service across a 4-year timeframe. METHOD: We compared two cohorts, and identified variables associated with being accepted or declined, and reasons for decline, by an EPI service between 2013 and 2017. RESULTS: There were 576 people with suspected psychosis referred to the EPI service for assessment: 300 (52%) were accepted, 221 (38%) declined and 55 (10%) were not processed. Reasons for being declined by EPI services were a long duration of psychosis (DUP, 48%) and no evidence of psychosis (47%). There were no significant differences between the accepted and declined group in Emergency Department presentations for self-harm or suicide attempts and acute admissions to a psychiatric inpatient unit over the 3-year follow-up period. CONCLUSION: To optimise the identification of true positive cases, EPI services require clear entry criteria. Replicating this study in other EPI services with different entry criteria may provide evidence to develop a more uniform screening process. Improved outcomes may be enhanced by measuring effectiveness and liaising with other EPI services.

Anti-dementia medication use in Aotearoa New Zealand: An exploratory study using health data from the Integrated Data Infrastructure (IDI).

OBJECTIVE: Anti-dementia medications such as acetylcholinesterase inhibitors are an important part of the management pathway for dementia. However, there are limited data in New Zealand that have examined the rates and patterns of use of funded anti-dementia medication and how use differs with ethnicity, age and sex. METHODS: This was a retrospective population-based descriptive study. Using the Integrated Data Infrastructure, we identified individuals of all ages coded for a diagnosis of dementia and estimated the proportion dispensed funded anti-dementia medication - donepezil tablets and rivastigmine patches - between 1 July 2016 and 30 June 2020. Rates of medication use in five main ethnic groups (Maori, Pacific peoples, Asian, European, and Middle Eastern, Latin American and African) in the <65, 65-79 and 80 and over (80+) age groups were compared and also between males and females in all sub-groups. Log-binomial models were used to calculate relative risks to determine any differences in anti-dementia medication use in the five ethnic groups and the three age groups and between males and females in each of the four study years. RESULTS: Overall, one-third of the dementia population received a funded anti-dementia medication in the total population (all ages) between 2016 and 2020. Donepezil tablets were dispensed in 31.6-34.0% and rivastigmine patches in 1.4-2.1% across the four study years. Compared to people of European ethnicity, Maori, Pacific peoples, and Middle Eastern, Latin American and African groups were less likely to be dispensed an anti-dementia medication (Maori: relative risk = 0.79-0.81, p < 0.0001; Pacific peoples: relative risk = 0.72-0.74, p < 0.0001; Middle Eastern, Latin American and African: relative risk = 0.73-0.78, p < 0.05). Compared to the age 80+ group, the 65-79 age group was more likely (relative risk = 1.50-1.54, p < 0.0001), while the age <65 group was less likely (relative risk = 0.67-0.71, p < 0.0001) to be dispensed an anti-dementia medication. There were no statistically significant differences in anti-dementia medication use between males and females. CONCLUSION: This study provides important information about funded anti-dementia medication use in New Zealand and how this differs by ethnicity, age and sex. Despite higher dementia prevalence in Maori and Pacific peoples, these groups were less likely to receive funded anti-dementia medication.

A survey of the psychiatric care provided for medically ill older adults in general hospitals in New Zealand.

OBJECTIVE: The aim of this study was to conduct an in-depth survey of the psychiatric care provided for medically ill older adults in general hospitals in New Zealand (NZ). METHOD: As part of a larger survey of Consultation-Liaison Psychiatry (CLP) services for all ages in NZ (CLPSNZ-2), a 44-question survey was emailed to clinicians who were involved in providing psychiatric care for medically ill older adults at each of the 16 general hospitals with designated CLP services. RESULTS: Responses were obtained from 22 services at 16 hospitals - 14 CLP services and eight Psychiatry of Old Age (POA) in-reach services. These services were found to be under-resourced, operate with highly variable service models, and predominantly provide inpatient consultations. Services could be conceptualised as six prototypes with variations of POA in-reach to hospitals, scope of CLP cover and collaboration between services. CONCLUSION: The heterogeneity in the psychiatric care for medically ill older adults in NZ means that there is an urgent need to develop more consistent CLP service models that better serve the specialist needs of older adults, and establish the policies, resources and standards needed to support them.

Prevalence of young-onset dementia: nationwide analysis of routinely collected data.

INTRODUCTION: Young-onset dementia prevalence is understudied internationally. Previous studies have been limited by low case numbers, reliance on single sources of routinely collected health data for case identification and inclusion of a limited age range. Our objective was to determine the 1-year period prevalence of diagnosed dementia in people aged 0-64 in the entire New Zealand population using routinely collected health data. METHODS: A population-based descriptive study was carried out in New Zealand (population 4.8 million) using routinely collected deidentified health data from 2016 to 2020. Dementia cases in seven linked health datasets in the New Zealand Integrated Data Infrastructure were identified using diagnostic codes and/or use of antidementia medication. Prevalence for each of the four study years was calculated by age, sex and ethnicity. RESULTS: From a total population of 4 027 332-4 169 754 individuals aged 0-64, we identified 3396-3474 cases of 'all-cause' dementia in each of the study years (prevalence crude range: 83-84/100 000 people aged 0-64; 139-141/100 000 people aged 30-64 years; 204-207/100 000 people aged 45-64 years). Age-standardised prevalence was higher in males than females. Age-standardised and sex-standardised prevalence was higher in Maori and Pacific People than European and Asian. DISCUSSION: By using a large study population and multiple national health datasets, we have minimised selection bias and estimated the national prevalence of diagnosed young-onset dementia with precision. Young-onset dementia prevalence for the total New Zealand population was similar to reported global prevalence, validating previous estimates. Prevalence differed by ethnicity, which has important implications for service planning.

Clinical judgement by primary care physicians for the diagnosis of all-cause dementia or cognitive impairment in symptomatic people.

BACKGROUND: In primary care, general practitioners (GPs) unavoidably reach a clinical judgement about a patient as part of their encounter with patients, and so clinical judgement can be an important part of the diagnostic evaluation. Typically clinical decision making about what to do next for a patient incorporates clinical judgement about the diagnosis with severity of symptoms and patient factors, such as their ideas and expectations for treatment. When evaluating patients for dementia, many GPs report using their own judgement to evaluate cognition, using information that is immediately available at the point of care, to decide whether someone has or does not have dementia, rather than more formal tests. OBJECTIVES: To determine the diagnostic accuracy of GPs' clinical judgement for diagnosing cognitive impairment and dementia in symptomatic people presenting to primary care. To investigate the heterogeneity of test accuracy in the included studies. SEARCH METHODS: We searched MEDLINE (Ovid SP), Embase (Ovid SP), PsycINFO (Ovid SP), Web of Science Core Collection (ISI Web of Science), and LILACs (BIREME) on 16 September 2021. SELECTION CRITERIA: We selected cross-sectional and cohort studies from primary care where clinical judgement was determined by a GP either prospectively (after consulting with a patient who has presented to a specific encounter with the doctor) or retrospectively (based on knowledge of the patient and review of the medical notes, but not relating to a specific encounter with the patient). The target conditions were dementia and cognitive impairment (mild cognitive impairment and dementia) and we included studies with any appropriate reference standard such as the Diagnostic and Statistical Manual of Mental Disorders (DSM), International Classification of Diseases (ICD), aetiological definitions, or expert clinical diagnosis. DATA COLLECTION AND ANALYSIS: Two review authors screened titles and abstracts for relevant articles and extracted data separately with differences resolved by consensus discussion. We used QUADAS-2 to evaluate the risk of bias and concerns about applicability in each study using anchoring statements. We performed meta-analysis using the bivariate method. MAIN RESULTS: We identified 18,202 potentially relevant articles, of which 12,427 remained after de-duplication. We assessed 57 full-text articles and extracted data on 11 studies (17 papers), of which 10 studies had quantitative data. We included eight studies in the meta-analysis for the target condition dementia and four studies for the target condition cognitive impairment. Most studies were at low risk of bias as assessed with the QUADAS-2 tool, except for the flow and timing domain where four studies were at high risk of bias, and the reference standard domain where two studies were at high risk of bias. Most studies had low concern about applicability to the review question in all QUADAS-2 domains. Average age ranged from 73 years to 83 years (weighted average 77 years). The percentage of female participants in studies ranged from 47% to 100%. The percentage of people with a final diagnosis of dementia was between 2% and 56% across studies (a weighted average of 21%). For the target condition dementia, in individual studies sensitivity ranged from 34% to 91% and specificity ranged from 58% to 99%. In the meta-analysis for dementia as the target condition, in eight studies in which a total of 826 of 2790 participants had dementia, the summary diagnostic accuracy of clinical judgement of general practitioners was sensitivity 58% (95% confidence interval (CI) 43% to 72%), specificity 89% (95% CI 79% to 95%), positive likelihood ratio 5.3 (95% CI 2.4 to 8.2), and negative likelihood ratio 0.47 (95% CI 0.33 to 0.61). For the target condition cognitive impairment, in individual studies sensitivity ranged from 58% to 97% and specificity ranged from 40% to 88%. The summary diagnostic accuracy of clinical judgement of general practitioners in four studies in which a total of 594 of 1497 participants had cognitive impairment was sensitivity 84% (95% CI 60% to 95%), specificity 73% (95% CI 50% to 88%), positive likelihood ratio 3.1 (95% CI 1.4 to 4.7), and negative likelihood ratio 0.23 (95% CI 0.06 to 0.40). It was impossible to draw firm conclusions in the analysis of heterogeneity because there were small numbers of studies. For specificity we found the data were compatible with studies that used ICD-10, or applied retrospective judgement, had higher reported specificity compared to studies with DSM definitions or using prospective judgement. In contrast for sensitivity, we found studies that used a prospective index test may have had higher sensitivity than studies that used a retrospective index test. AUTHORS' CONCLUSIONS: Clinical judgement of GPs is more specific than sensitive for the diagnosis of dementia. It would be necessary to use additional tests to confirm the diagnosis for either target condition, or to confirm the absence of the target conditions, but clinical judgement may inform the choice of further testing. Many people who a GP judges as having dementia will have the condition. People with false negative diagnoses are likely to have less severe disease and some could be identified by using more formal testing in people who GPs judge as not having dementia. Some false positives may require similar practical support to those with dementia, but some - such as some people with depression - may suffer delayed intervention for an alternative treatable pathology.

Modelling vulnerability: qualitative study of the Balint process for medical students.

BACKGROUND: Health professionals in training may be overwhelmed by the emotional dimensions of their work. Balint groups have been proposed as an intervention to support students to process emotional aspects their encounters with patients. The aim of this study was to explore medical students' emotional experiences of a Balint group during their psychiatry attachment. METHODS: Medical students completing a six week clinical attachment in psychiatry took part in weekly Balint group sessions. Five sessions were audio-recorded, transcribed and coded by members of the research team and an independent researcher co-coded all transcripts. Themes were discussed and refined over three rounds of coding. RESULTS: Four themes were identified: the Balint process as a container to enable vulnerability; becoming attuned to clinical and professional encounters; an evolving sense of identity within the medical hierarchy; and, the need for self-preservation to retain empathy for others. CONCLUSION: The Balint structure provides medical students with a secure and emotionally resonant experience. Medical students' engagement with the Balint process, even over a relatively short time period, teaches them how to reflect on difficult emotions associated with clinical encounters. Early exposure during a psychiatry placement may benefit students in terms of understanding relationship dynamics and the need for self-integration and lifelong reflection over the course of their medical career.

Stigma in Consultation Liaison Psychiatry: A Qualitative Study of Trainee Psychiatrists.

OBJECTIVE: Stigma related to mental illness can impact service-user care and clinician wellbeing. The aim of this study was to explore experiences of stigma in consultation-liaison psychiatry from the perspectives of trainee psychiatrists and suggest interventions to tackle stigma within a hospital environment. METHOD: Ethics approval and consent were obtained for the study. In-depth interviews were conducted by telephone with six participants in four New Zealand district health boards. De-identified data was analysed using thematic analysis. An independent co-coder was employed to enhance analytic rigour. RESULTS: Participants experienced stigma during their consultation-liaison rotations. Some felt isolated and undervalued. Education, intergration and role clarification within the hospital environment were identified as ways to reduce stigma. CONCLUSIONS: Stigma experienced by trainee psychiatrists completing consultation-liaison rotations may lead to them feeling devalued and perceiving service-users to experience poorer care. Multidisciplinary education may potentially combat stigma and contribute to improved integration of services.

The evidence for introducing case-finding for delirium and dementia in older medical inpatients in a New Zealand hospital.

OBJECTIVE: The aim of this project was to make the case to the managers of a large urban teaching hospital in New Zealand for the introduction of systematic case-finding for pre-existing cognitive impairment/dementia in older hospital inpatients that screen positive for delirium. METHOD: Two hundred consecutive acute admissions aged 75+ in four medical wards were assessed using the 4AT assessment tool for delirium and the Alzheimer Questionnaire (AQ) for pre-existing cognitive impairment/dementia. Length of stay and mortality at 1 year were also collected. RESULTS: Over a third of the sample screened positive for delirium and nearly two-thirds of these also screened positive for dementia. The median length of stay was 5 days for delirium without dementia and 7 days for delirium with dementia, compared to 3 days for those who screened negative for both. After adjustment for age, gender and ethnic group, people who screened positive for delirium (with or without dementia) had 50% longer length of stay (p < 0.05) and at least double the risk of death (p < 0.05). CONCLUSION: Older hospital inpatients that screen positive for delirium and dementia using 4AT and AQ have longer lengths of stay and higher mortality. Identification may lead to more timely interventions that help to improve health outcomes and reduce hospital costs.

Montreal Cognitive Assessment for the detection of dementia.

BACKGROUND: Dementia is a progressive syndrome of global cognitive impairment with significant health and social care costs. Global prevalence is projected to increase, particularly in resource-limited settings. Recent policy changes in Western countries to increase detection mandates a careful examination of the diagnostic accuracy of neuropsychological tests for dementia. OBJECTIVES: To determine the accuracy of the Montreal Cognitive Assessment (MoCA) for the detection of dementia. SEARCH METHODS: We searched MEDLINE, EMBASE, BIOSIS Previews, Science Citation Index, PsycINFO and LILACS databases to August 2012. In addition, we searched specialised sources containing diagnostic studies and reviews, including MEDION (Meta-analyses van Diagnostisch Onderzoek), DARE (Database of Abstracts of Reviews of Effects), HTA (Health Technology Assessment Database), ARIF (Aggressive Research Intelligence Facility) and C-EBLM (International Federation of Clinical Chemistry and Laboratory Medicine Committee for Evidence-based Laboratory Medicine) databases. We also searched ALOIS (Cochrane Dementia and Cognitive Improvement Group specialized register of diagnostic and intervention studies). We identified further relevant studies from the PubMed 'related articles' feature and by tracking key studies in Science Citation Index and Scopus. We also searched for relevant grey literature from the Web of Science Core Collection, including Science Citation Index and Conference Proceedings Citation Index (Thomson Reuters Web of Science), PhD theses and contacted researchers with potential relevant data. SELECTION CRITERIA: Cross-sectional designs where all participants were recruited from the same sample were sought; case-control studies were excluded due to high chance of bias. We searched for studies from memory clinics, hospital clinics, primary care and community populations. We excluded studies of early onset dementia, dementia from a secondary cause, or studies where participants were selected on the basis of a specific disease type such as Parkinson's disease or specific settings such as nursing homes. DATA COLLECTION AND ANALYSIS: We extracted dementia study prevalence and dichotomised test positive/test negative results with thresholds used to diagnose dementia. This allowed calculation of sensitivity and specificity if not already reported in the study. Study authors were contacted where there was insufficient information to complete the 2x2 tables. We performed quality assessment according to the QUADAS-2 criteria. Methodological variation in selected studies precluded quantitative meta-analysis, therefore results from individual studies were presented with a narrative synthesis. MAIN RESULTS: Seven studies were selected: three in memory clinics, two in hospital clinics, none in primary care and two in population-derived samples. There were 9422 participants in total, but most of studies recruited only small samples, with only one having more than 350 participants. The prevalence of dementia was 22% to 54% in the clinic-based studies, and 5% to 10% in population samples. In the four studies that used the recommended threshold score of 26 or over indicating normal cognition, the MoCA had high sensitivity of 0.94 or more but low specificity of 0.60 or less. AUTHORS' CONCLUSIONS: The overall quality and quantity of information is insufficient to make recommendations on the clinical utility of MoCA for detecting dementia in different settings. Further studies that do not recruit participants based on diagnoses already present (case-control design) but apply diagnostic tests and reference standards prospectively are required. Methodological clarity could be improved in subsequent DTA studies of MoCA by reporting findings using recommended guidelines (e.g. STARDdem). Thresholds lower than 26 are likely to be more useful for optimal diagnostic accuracy of MoCA in dementia, but this requires confirmation in further studies.

Mini-Mental State Examination (MMSE) for the early detection of dementia in people with mild cognitive impairment (MCI).

BACKGROUND: Dementia is a progressive global cognitive impairment syndrome. In 2010, more than 35 million people worldwide were estimated to be living with dementia. Some people with mild cognitive impairment (MCI) will progress to dementia but others remain stable or recover full function. There is great interest in finding good predictors of dementia in people with MCI. The Mini-Mental State Examination (MMSE) is the best-known and the most often used short screening tool for providing an overall measure of cognitive impairment in clinical, research and community settings. OBJECTIVES: To determine the accuracy of the Mini Mental State Examination for the early detection of dementia in people with mild cognitive impairment SEARCH METHODS: We searched ALOIS (Cochrane Dementia and Cognitive Improvement Specialized Register of diagnostic and intervention studies (inception to May 2014); MEDLINE (OvidSP) (1946 to May 2014); EMBASE (OvidSP) (1980 to May 2014); BIOSIS (Web of Science) (inception to May 2014); Web of Science Core Collection, including the Conference Proceedings Citation Index (ISI Web of Science) (inception to May 2014); PsycINFO (OvidSP) (inception to May 2014), and LILACS (BIREME) (1982 to May 2014). We also searched specialized sources of diagnostic test accuracy studies and reviews, most recently in May 2014: MEDION (Universities of Maastricht and Leuven, www.mediondatabase.nl), DARE (Database of Abstracts of Reviews of Effects, via the Cochrane Library), HTA Database (Health Technology Assessment Database, via the Cochrane Library), and ARIF (University of Birmingham, UK, www.arif.bham.ac.uk). No language or date restrictions were applied to the electronic searches and methodological filters were not used as a method to restrict the search overall so as to maximize sensitivity. We also checked reference lists of relevant studies and reviews, tracked citations in Scopus and Science Citation Index, used searches of known relevant studies in PubMed to track related articles, and contacted research groups conducting work on MMSE for dementia diagnosis to try to locate possibly relevant but unpublished data. SELECTION CRITERIA: We considered longitudinal studies in which results of the MMSE administered to MCI participants at baseline were obtained and the reference standard was obtained by follow-up over time. We included participants recruited and clinically classified as individuals with MCI under Petersen and revised Petersen criteria, Matthews criteria, or a Clinical Dementia Rating = 0.5. We used acceptable and commonly used reference standards for dementia in general, Alzheimer's dementia, Lewy body dementia, vascular dementia and frontotemporal dementia. DATA COLLECTION AND ANALYSIS: We screened all titles generated by the electronic database searches. Two review authors independently assessed the abstracts of all potentially relevant studies. We assessed the identified full papers for eligibility and extracted data to create two by two tables for dementia in general and other dementias. Two authors independently performed quality assessment using the QUADAS-2 tool. Due to high heterogeneity and scarcity of data, we derived estimates of sensitivity at fixed values of specificity from the model we fitted to produce the summary receiver operating characteristic curve. MAIN RESULTS: In this review, we included 11 heterogeneous studies with a total number of 1569 MCI patients followed for conversion to dementia. Four studies assessed the role of baseline scores of the MMSE in conversion from MCI to all-cause dementia and eight studies assessed this test in conversion from MCI to Alzheimer´s disease dementia. Only one study provided information about the MMSE and conversion from MCI to vascular dementia. For conversion from MCI to dementia in general, the accuracy of baseline MMSE scores ranged from sensitivities of 23% to 76% and specificities from 40% to 94%. In relationship to conversion from MCI to Alzheimer's disease dementia, the accuracy of baseline MMSE scores ranged from sensitivities of 27% to 89% and specificities from 32% to 90%. Only one study provided information about conversion from MCI to vascular dementia, presenting a sensitivity of 36% and a specificity of 80% with an incidence of vascular dementia of 6.2%. Although we had planned to explore possible sources of heterogeneity, this was not undertaken due to the scarcity of studies included in our analysis. AUTHORS' CONCLUSIONS: Our review did not find evidence supporting a substantial role of MMSE as a stand-alone single-administration test in the identification of MCI patients who could develop dementia. Clinicians could prefer to request additional and extensive tests to be sure about the management of these patients. An important aspect to assess in future updates is if conversion to dementia from MCI stages could be predicted better by MMSE changes over time instead of single measurements. It is also important to assess if a set of tests, rather than an isolated one, may be more successful in predicting conversion from MCI to dementia.

Predictors of mortality in Maori, Pacific Island, and European patients diagnosed with dementia at a New Zealand Memory Service.

BACKGROUND: As the economic impact of dementia on health and social care increases, governments require disease-specific epidemiological data that will help inform spending and policy decisions. The aim of this study is to examine predictors of mortality in dementia in consecutive referrals to a New Zealand (NZ) memory service that includes Maori, Pacific Islander, and NZ European patients. METHODS: Date of birth, sex, ethnicity, living situation, cognitive function, dementia subtype, dementia severity, physical comorbidity, and medication data were collected from electronic health records. The resulting data set was linked to administrative data on mortality and last hospital contact dates to allow time-dependent survival analyses. RESULTS: The risk of death in people with dementia was increased by age (adjusted HR per year 1.08, 95%CI:1.05-1.12) and lower cognitive score at baseline (adjusted HR for severe impairment:2.54, 95% CI:1.25-5.16), and was reduced by cholinesterase inhibitors (adjusted HR:0.54, 95% CI:0.34-0.88). Compared to NZ Europeans (HR:1.19, 95% CI:0.63-2.25), antipsychotics increased the risk of death three-fold in Maori (adjusted HR:3.62, 95% CI:0.79-16.7) and Pacific Islanders (adjusted HR:2.54, 95%CI:1.10-5.85). CONCLUSIONS: Further research is required to elucidate the mechanisms underlying the survival rates in Maori and Pacific Islanders living with dementia in NZ,and their increased risk of death if antipsychotics are used.

A qualitative study on conveyance decision-making during emergency call outs to people with dementia: the HOMEWARD project.

BACKGROUND: Paramedics are increasingly required to make complex decisions as to whether they should convey a patient to hospital or manage their condition at the scene. Dementia can be a significant barrier to the assessment process. However, to our knowledge no research has specifically examined the process of decision-making by paramedics in relation to people with dementia. This qualitative study was designed to investigate the factors influencing the decision-making process during Emergency Medical Services (EMS) calls to older people with dementia who did not require immediate clinical treatment. METHODS: This qualitative study used a combination of observation, interview and document analysis to investigate the factors influencing the decision-making process during EMS calls to older people with dementia. A researcher worked alongside paramedics in the capacity of observer and recruited eligible patients to participate in case studies. Data were collected from observation notes of decision-making during the incident, patient care records and post incident interviews with participants, and analysed thematically. FINDINGS: Four main themes emerged from the data concerning the way that paramedics make conveyance decisions when called to people with dementia: 1) Physical condition; the key factor influencing paramedics' decision-making was the physical condition of the patient. 2) Cognitive capacity; most of the participants preferred not to remove patients with a diagnosis of dementia from surroundings familiar to them, unless they deemed it absolutely essential. 3) Patient circumstances; this included the patient's medical history and the support available to them. 4) Professional influences; participants also drew on other perspectives, such as advice from colleagues or information from the patient's General Practitioner, to inform their decision-making. CONCLUSION: The preference for avoiding unnecessary conveyance for patients with dementia, combined with difficulties in obtaining an accurate patient medical history and assessment, mean that decision-making can be particularly problematic for paramedics. Further research is needed to find reliable ways of assessing patients and accessing information to support conveyance decisions for EMS calls to people with dementia.

The multi-dimensional matrix for consultation-liaison psychiatry (mMAX-LP).

OBJECTIVE: Consultation-liaison psychiatry (CLP) services are particularly susceptible to heterogeneity, developing haphazardly in response to local interests and perceived need. This hampers the generalisability of comparisons between services in terms of service models, resource requirements and outcome data. The objective of this paper therefore is to chronicle the development of a method to meaningfully describe, map and compare different CLP services. METHOD: A review of the literature was followed by multiple site visits in both New Zealand and England, and an extended process of consultation and feedback. RESULTS: Sixteen dimensions common to CLP services were extracted to create a multi-dimensional matrix (mMAX-LP) which had three broad clusters (structure, coverage and relationship with physical health services). The model was applied and discussed with the previously visited hospitals over the succeeding five years. Additionally, the matrix was tested, and its utility demonstrated during the planned reconfiguration of CLP services at a large teaching hospital in South Auckland, New Zealand by tracking the evolution of CLP services. CONCLUSIONS: mMAX-LP shows promise as a useful model for profiling and comparing CLP services; mapping their evolution over time; and sign-posting future service development.

The state of play - the first national survey of consultation-liaison psychiatry services in New Zealand.

OBJECTIVE: The aim of this study was to conduct the first national survey of consultation-liaison psychiatry (CLP) services in New Zealand. METHOD: An online survey based on the Multidimensional Matrix for Consultation-Liaison Psychiatry (mMAX-LP) was circulated to a psychiatrist at each of 12 identified CLP services nationally during April-May 2018. Existing data for Middlemore Hospital (where the lead author is based) were added later for completion. RESULTS: Most CLP services in New Zealand are funded and managed by the mental health division, operate within office hours, and have psychologists and other allied health staff external to their service. However, there was significant heterogeneity amongst these services in terms of structure and function and in particular, the coverage of emergency departments and young/older patient groups. CONCLUSION: This first national survey has provided a snapshot of CLP services in New Zealand in 2018 and found striking heterogeneity. The survey has established a baseline for future local and international comparisons.

Perspectives of dementia from Asian communities living in New Zealand: A focus group of Asian health care professionals.

OBJECTIVE: The number of Asian New Zealanders with dementia is growing. The objective of this study was to explore with a group of Asian health care professionals about public attitudes towards dementia in Asian communities in New Zealand, the stigma of dementia, and how best to develop culturally appropriate services for Asian people and families living with dementia. METHODS: A focus group was conducted with a group of bilingual Asian health care professionals. A topic guide was developed based on the discussion at a prior meeting with the Cross Cultural Interest Group. The data were independently analysed by three researchers using the thematic qualitative methodology. RESULTS: Eleven overseas-born Asian health care professionals (Chinese: n = 9, 82%) participated in the focus group. Four main themes emerged from the data: (a) cultural interpretations of dementia; (b) stigma; (c) filial piety; and (d) inequity in the availability of resources. CONCLUSION: Our findings suggest that much work is needed to destigmatise dementia in New Zealand Asian communities, through psychoeducation, public awareness, and the availability of readily accessible services that can meet their cultural and language needs.

Do community-dwelling Maori and Pacific peoples present with dementia at a younger age and at a later stage compared with NZ Europeans?

OBJECTIVE: Ethnicity may affect presentation to clinical services in people with dementia; however, no studies have examined this in Maori or Pacific peoples in New Zealand (NZ). Our objective was to examine the routinely collected clinical data from a memory assessment service in South Auckland to examine the presentation of dementia in the major NZ ethnic groups. METHODS: A total of 360 patients presenting to a memory service with a new diagnosis of dementia were included in this study. Demographic data (age, sex, and ethnicity) and dementia sub-type and severity were analyzed. RESULTS: There were 142 NZ European (mean age: 79.2, SD 7.4), 43 Maori (mean age: 70.2, SD 7.6), 126 Pacific (mean age: 74.3, SD 7.6), and 49 other ethnicities (mean age: 78.0, SD 8.5) presenting with a new diagnosis of dementia. After adjustment for gender and dementia subtype, Maori and Pacific patients were 8.5 and 5.3 years younger than NZ European patients (P < 0.0001). Pacific peoples tended to present with more advanced dementia (OR = 1.63, 95% CI: 0.98-2.70, P = 0.06) after adjustment for age and gender. There was little difference in the subtypes of dementia between ethnic groups. CONCLUSIONS: Maori and Pacific peoples with dementia presented to an NZ memory service at a younger age than NZ Europeans, and Pacific peoples presented with more advanced dementia. A population-based epidemiological study is critical to determine whether Maori and Pacific peoples have indeed a higher risk of developing dementia at a younger age.

Supervising trainees in research: what does it take to be a scholarly project supervisor?

OBJECTIVES: Scholarly projects (SPs) are a compulsory component of psychiatry training in Australasia. This article outlines the role of a research supervisor in supporting a trainee to complete an SP. METHODS: A total of 10 old age and forensic psychiatry SPs were reviewed with regard to aims, methodology, supervisor input, trainee tasks and additional resources. RESULTS: The main supervisor tasks are described and discussed. They include practical advice on study design, ethics applications, critical appraisal, data analysis, academic writing and publication. CONCLUSIONS: Supervising SPs can bring significant rewards in awakening a trainee's interest in research. Key competencies for research supervision are discussed and further recommendations for supervisor support and training are provided.

Use of ECT in the presence of acute bilateral posterior vitreous detachmanet.

OBJECTIVES: We describe a case of acute bilateral posterior vitreous detachment (PVD) in a 71-year-old female, which developed during a course of electroconvulsive therapy (ECT) for treatment-resistant depression. The risks and benefits of continuing ECT were assessed and the patient completed the full course of 16 ECT treatments without further ophthalmic complications. CONCLUSIONS: As the incidence of PVD increases with age, and ECT is used more frequently in elderly people with depression, we recommend paying attention to ophthalmic symptoms as part of the routine clinical monitoring of ECT side effects. If ophthalmic symptoms occur, the risks and benefits of ECT need to be weighed up including consultation with an ophthalmologist.
