Psychosocial and behavioural interventions for the negative symptoms of schizophrenia: a systematic review of efficacy meta-analyses.

BACKGROUND: Currently there is no first-line treatment recommended for the negative symptoms of schizophrenia. Psychosocial and behavioural interventions are widely used to reduce the burden of negative symptoms. Meta-analytic studies have summarised the evidence for specific approaches but not compared evidence quality and benefit. AIM: To review and evaluate the evidence from meta-analytic studies of psychosocial and behavioural interventions for the negative symptoms of schizophrenia. METHOD: A systematic literature search was undertaken to identify all meta-analyses evaluating psychosocial and behavioural interventions reporting on negative symptom outcomes in people with schizophrenia. Data on intervention, study characteristics, acceptability and outcome were extracted. Risk of bias was evaluated. Results were summarised descriptively, and evidence ranked on methodological quality. RESULTS: In total, 31 systematic reviews met the inclusion criteria evaluating the efficacy of negative symptom interventions on 33 141 participants. Exercise interventions showed effect sizes (reduction in negative symptoms) ranging from -0.59 to -0.24 and psychological interventions ranging from -0.65 to -0.04. Attrition ranged between 12% to 32%. Across the studies considered heterogeneity varied substantially (range 0-100). Most of the reviews were of very low to low methodological quality. Methodological quality ranking suggested that the effect size for cognitive remediation and exercise therapy may be more robust compared with other approaches. CONCLUSIONS: Most of the interventions considered had a small-to-moderate effect size, good acceptability levels but very few had negative symptoms as the primary intervention target. To improve the confidence of these effect sizes being replicated in clinical settings future studies should minimise risk of bias.

Risk of first-episode psychosis in migrants to the Republic of Ireland.

BACKGROUND: Migration is an established risk factor for developing a psychotic disorder in countries with a long history of migration. Less is known for countries with only a recent history of migration. This study aimed to determine the risk for developing a psychotic disorder in migrants to the Republic of Ireland. METHODS: We included all presentations of first-episode psychosis over 8.5 years to the DETECT Early Intervention for psychosis service in the Republic of Ireland (573 individuals aged 18-65, of whom 22% were first-generation migrants). Psychotic disorder diagnosis relied on SCID. The at-risk population was calculated using census data, and negative binomial regression was used to estimate incidence rate ratios. RESULTS: The annual crude incidence rate for a first-episode psychotic disorder in the total cohort was 25.62 per 100000 population at risk. Migrants from Africa had a nearly twofold increased risk for developing a psychotic disorder compared to those born in the Republic of Ireland (IRR = 1.83, 95% CI 1.11-3.02, p = 0.02). In contrast, migrants from certain Asian countries had a reduced risk, specifically those from China, India, Philippines, Pakistan, Malaysia, Bangladesh and Hong Kong (aIRR = 0.36, 95% CI 0.16-0.81, p = 0.01). CONCLUSIONS: Further research into the reasons for this inflated risk in specific migrant groups could produce insights into the aetiology of psychotic disorders. This information should also be used, alongside other data on environmental risk factors that can be determined from census data, to predict the incidence of psychotic disorders and thereby resource services appropriately.

Early intervention in psychosis: health economic evaluation using the net benefit approach in a real-world setting.

BACKGROUND: Early intervention in psychosis is a complex intervention, usually delivered in a specialist stand-alone setting, which aims to improve outcomes for people with psychosis. Previous studies have been criticised because the control used did not accurately reflect actual practice. AIMS: To evaluate the cost-effectiveness of early intervention by estimating the incremental net benefit (INB) of an early-intervention programme, delivered in a real-world setting. INB measures the difference in monetary terms between alternative interventions. METHOD: Two contemporaneous incidence-based cohorts presenting with first-episode psychosis, aged 18-65 years, were compared. Costs and outcomes were measured over 1 year. The main outcome was avoidance of a relapse that required admission to hospital or home-based treatment. RESULTS: From the health sector perspective, the probability that early intervention was cost-effective was 0.77. The INB was €2465 per person (95% CI - €4418 to €9347) when society placed a value of €6000, the cost of an in-patient relapse, on preventing a relapse requiring admission or home care. Following adjustment, the probability that early intervention was cost-effective was 1, and the INB to the health sector was €3105 per person (95% CI -€8453 to €14 663). From a societal perspective, the adjusted probability that early intervention was cost-effective was 1, and the INB was €19 928 per person (95% CI - €2075 to €41 931). CONCLUSIONS: Early intervention has a modest INB from the health sector perspective and a large INB from the societal perspective. The perspective chosen is critical when presenting results of an economic evaluation of a complex intervention.

Care Pathways in a Suicide Crisis Assessment Nurse (SCAN) service.

AIM: The Suicide Crisis Assessment Nurse service has been developed as a Primary Care suicide intervention over the last decade. The current study aimed to describe the demographic details of users of this nurse led service, and to evaluate subsequent care pathways following this intervention. METHODS: This study was conducted using a retrospective file review with a cross-sectional observational design investigating demographic details of service users and care pathways in a Suicide Crisis Assessment Nurse service within a defined catchment area of Ireland between June 2015 and May 2017. RESULTS: The majority of referrals were managed in Primary Care following Suicide Crisis Assessment Nurse intervention. There was an increase in Primary Care management pathway in the second year of the service which was independent of age and gender. CONCLUSION: There was an increase in referrals to the service over time, and the majority of presentations were managed in primary care following Suicide Crisis Assessment Nurse intervention. The study suggests that primary care interventions for suicidal crises merit further research.

The therapeutic relationship after psychiatric admission.

The therapeutic relationship is one of the most central and important factors in the treatment of mental health disorders. A better therapeutic relationship is associated with service engagement, medication adherence, and satisfaction with services. This study aimed to compare the demographic and clinical factors associated with the therapeutic relationship in voluntarily and involuntarily admitted psychiatric service users. We found that individuals who had been admitted involuntarily, who had a diagnosis of a psychotic disorder, and who reported higher levels of perceived pressures on admission were more likely to have a poorer therapeutic relationship with their consultant psychiatrist. Greater levels of insight and treatment satisfaction, together with higher levels of procedural justice experienced on admission, were associated with a better therapeutic relationship. We found that the level of perceived coercion on admission was not related to the therapeutic relationship. Targeted interventions to improve the therapeutic relationship, particularly for involuntarily admitted service users, are discussed.

Satisfaction with services following voluntary and involuntary admission.

BACKGROUND: Service user perspectives are essential for the evaluation and development of mental health services. Service users expressing less satisfaction with services subsequently have poorer treatment outcomes. AIMS: To measure satisfaction with services following psychiatric admission, and to explore its relationship with a number of clinical and service factors. METHODS: A multi-centre observational study was conducted across three mental health services in Ireland. Service users were interviewed and provided with self-report questionnaires. The Client Satisfaction Questionnaire (CSQ-8) was used to measure treatment satisfaction. RESULTS: The overall level of satisfaction with services was good (CSQ-8 mean score 24.5). Service users who were admitted involuntarily, who experienced physical coercion and lower levels of procedural justice were less satisfied. A better therapeutic relationship, improved insight and better functioning were associated with higher levels of treatment satisfaction. CONCLUSION: Mental health services should implement strategies to ameliorate the effects of factors associated with lower levels of treatment satisfaction.

Attachment theory: survival, trauma, and war through the eyes of Bowlby.

Children are no strangers to war and conflict, and for as long as history has been documented, so too has the negative impact of war on children. Attachment theory, which has shone a light upon the ways in which early life experiences can impact individuals across the lifespan, is a helpful lens through which we can view the consequences of war. Similar to the aftermath of war leading to lifelong and transgenerational suffering due to deaths and physical health issues, attachment difficulties created during war further compound long-term damage. Yet, despite our theoretical understanding of the detrimental impact of war on children and on humankind, humanity has failed to find ways to avert, or at least minimise, this unfortunate risk. Instead in this century, we see a growing number of conflicts globally with increasing asylum seekers. In this editorial, we argue that the large-scale disruption to attachment relationships caused by conflict and war is an important consideration for global policy, and that the healthcare community must show leadership in highlighting this serious impact of war.

Response rates to sequential trials of antipsychotic medications according to algorithms or treatment guidelines in psychotic disorders. A systematic review and meta-analysis.

BACKGROUND: There is a relative lack of research evaluating the outcomes when treatment guidelines or algorithms for psychotic disorders are followed. This systematic review and meta-analysis determined the response rates to antipsychotic medications at different stages of these algorithms and whether these response rates differ in first episode cohorts. METHODS: Data sources: A systematic search strategy was conducted across four databases PubMed, EMBASE, PsycINFO (Ovid) and CINAHL. Studies that had sequential trials of different antipsychotic medications were included. A meta-analysis of proportions was performed using random effects models and sub-group analysis in first episode psychosis studies. RESULTS: Of the 4078 unique articles screened, fourteen articles, from nine unique studies, were eligible and included 2522 participants. The proportion who experienced a response to any antipsychotic in the first stage of an algorithm was 0.53 (95 % C.I.:0.38,0.68) and this decreased to 0.26 (95 % C.I.:0.15,0.39) in the second stage. When clozapine was used in the third stage, the proportion that achieved a response was 0.43 (95 % C.I. 0.19, 0.69) compared to 0.26 (95 % C.I.:0.05,0.54) if a different antipsychotic was used. Four studies included 907 participants with a first episode of psychosis and the proportions that achieved a response were: 1st stage: 0.63 (95 % C.I.: 0.45, 0.79); 2nd stage: 0.34 (95 % C.I.:0.16,0.55); clozapine 3rd stage: 0.45 (95 % C.I.:0.0,0.97), different antipsychotic 3rd stage: 0.15 (95 % C.I.,0.01,0.37). DISCUSSION: These findings support the recommendation to have a trial of clozapine after two other antipsychotic medications have been found to be ineffective.

Impact factor and future directions for the Irish Journal of Psychological Medicine.

Impact factor (IF) is a concept dating back over half a century, created to evaluate the impact of a journal within a particular scientific field. In spite of limitations, IF remains a widely used metric for journals to establish the average number of citations for articles published in a journal. The Irish Journal of Psychological Medicine (IJPM) recently received an IF of 5.1, the first IF for the journal. We believe that this is a reflection of the hard work and dedication of our authors, reviewers, publishers and editorial board. The IJPM is the official research journal of the College of Psychiatrists of Ireland, and while psychiatry is the primary discipline of the journal, the current multidisciplinary approach will continue into the future. The journal has a strong Irish and international readership; while the journal will continue to publish research with an Irish focus, the editorial team are aware of the importance of ongoing global contributions to ensure the journal maintains high-quality publications of an international standard. This is an exciting time to be involved in mental health research, and the journal will continue to publish cutting edge themes with the goal of improving mental healthcare in Ireland and beyond.

Outcomes 1 year after a first episode of psychosis in migrants to the Republic of Ireland.

BACKGROUND: Migration is a robust risk factor for developing a psychotic disorder, yet there is a paucity of research on the outcomes of migrants who develop a psychotic disorder. Identifying sub-groups within FEP cohorts who have a poorer outcome, could assist in the development and delivery of more targeted interventions. AIMS: There is a paucity of research on the outcomes of migrants who develop a psychotic disorder. This study aimed to evaluate a broad range of outcomes for those with a FEP who migrated to the Republic of Ireland, including: (i) symptomatic; (ii) functional; (iii) hospitalisation and (iv) engagement with psychosocial services. METHODS: All individuals with a FEP aged 18 to 65 who presented between 01.02.2006 and 01.07.2014 were included. Structured and validated instruments were used to measure positive, negative, depressive symptoms and insight. RESULTS: Of the 573 individuals with a FEP, 22.3% were first-generation migrants and 63.4% (n = 363) were followed up at 1 year. At this time, 72.4% of migrants were in remission of positive psychotic symptoms compared to 78.5% of the Irish born (OR = 0.84, 95% CI [0.50-1.41], p = .51). In relation to negative symptoms, 60.5% of migrants were in remission compared to 67.2% of the Irish born (OR = 0.75, 95% CI [0.44-1.27], p = .283). There was no difference in the severity of positive, negative or depressive symptoms between groups and there was a trend for the Irish born to have better insight (p = .056). The functional outcomes were similar across groups. One third of migrants were admitted to hospital compared to 28.7% of the Irish born (OR = 1.24, 95% CI [0.73-2.13], p = .426). Just over half of both groups attended CBT and 46.2% of caregivers for migrants attended the psychoeducation programme, compared to 39.7% for the Irish born (OR = 1.30, 95% CI [0.79-2.16], p = .306). CONCLUSIONS: These findings demonstrate that migrants have broadly similar outcomes to the native-born populations, however there is still considerable scope for the outcomes for all individuals affected by psychotic disorders to be improved.

Turning the Spotlight on Apathy: Identification and Treatment in Schizophrenia Spectrum Disorders.

Among negative symptoms, apathy is central to the impairments in real-life functioning in schizophrenia spectrum disorders (SSD). Thus, optimizing treatment for apathy appears key to improve outcomes. In treatment research, however, negative symptoms are typically studied as a unifactorial construct. We, therefore, aim to shed necessary light on the status of apathy identification and treatment in SSD.

Keyworker mediated enhancement of physical health in patients with first episode psychosis: A feasibility/acceptability study.

AIM: Early intervention for people experiencing first episode psychosis is a priority, and keyworkers are vital to such services. However, keyworkers' roles in addressing first episode psychosis patients' physical health are under researched. This study addresses this knowledge gap by evaluating a keyworker-mediated intervention promoting physical health among first episode psychosis patients. METHODS: The study was informed by the Medical Research Council's Framework for Complex Interventions to Improve Health. First episode psychosis participants were recruited from three Irish mental health services. The intervention was evaluated in terms of its feasibility/acceptability. RESULTS: Feasibility outcomes were mixed (recruitment rate = 24/68 [35.3%]; retention rate = 18/24 [75%]). The baseline sample was predominantly male (M:F ratio = 13:6; Med age = 25 y; IQR = 23-42 y). Common health issues among participants included overweightness/obesity (n = 11) and substance use (smoking/alcohol consumption [n = 19]). Participants' initial health priorities included exercising more (n = 10), improving diet (n = 6), weight loss (n = 7) and using various health/healthcare services. The intervention's acceptability was evidenced by the appreciation participants had for physical health keyworkers' support, as well as the healthy lifestyle, which the intervention promoted. Acceptability was somewhat compromised by a low-recruitment rate, variable linkages between keyworkers and general practitioners (GPs) and COVID-19 restrictions. CONCLUSIONS: Physical health-oriented keyworker interventions for first episode psychosis patients show promise and further evaluation of such initiatives is warranted. Future interventions should be mindful of participant recruitment challenges, strategies to enhance relationships between keyworkers and GPs, and if necessary, they should mitigate COVID-19 restrictions' impacts on care.

Comorbid psychiatric diagnoses among individuals presenting to an addiction treatment program for alcohol dependence.

A retrospective patient record review was conducted to examine comorbid psychiatric diagnoses, and comorbid substance use, among 465 patients below 45 years of age, presenting to a national alcohol addiction treatment unit in Dublin, between 1995 and 2006. Rates were high for depressive disorder (25.3%) particularly among females (35.4%). Lifetime reported use of substances other than alcohol was 39.2%, and further analysis showed significantly higher rates of deliberate self-harm among this group. Lifetime reported use of ecstasy was also significantly associated with depression in this alcohol-dependent population using logistic regression analysis. Implications and limitations of the findings are discussed.

Advanced paediatric conscious sedation: an alternative to dental general anaesthetic in the U.K.

BACKGROUND: Child dental anxiety is widespread, and it is not always possible to treat children using traditional methods such as behavioural management, local anaesthesia and even relative analgesia. In such cases a dental general anaesthetic (DGA) is the only option available to facilitate dental treatment in anxious children. AIM: This study describes an advanced conscious sedation protocol which allows invasive treatment to be carried out in anxious children. It incorporates the use of titrated intravenous midazolam and fentanyl and inhalation agents, sevoflurane and nitrous oxide/oxygen, which is administered by a Consultant Anaesthetist. The aim is to produce an evidence- based study which can offer a sedation technique as a safe and effective alternative to a DGA. STUDY DESIGN: Retrospective audit. METHOD: 267 clinical records were audited retrospectively from a specialist sedation-based clinic, for children aged 5-15 years old. The subjects all underwent invasive dental procedures with this technique between August and November 2008 as an alternative to a DGA. RESULTS: 262/267 (98%) of the subjects were treated safely and successfully and without the loss of verbal communication using this technique. This included many treatments requiring four quadrant dentistry, with both restorations and extractions as necessary being carried out in one visit. 5 subjects (2%) did not tolerate treatment and had to be referred for a DGA. No medical emergencies occurred. CONCLUSIONS: Based on the evidence for this group of patients, this advanced conscious sedation technique, offers a safe and effective alternative to DGA. This technique must be carried out in an appropriate environment by an appropriately trained and experienced team who are able to comply with the recommendations for "alternative" sedation techniques.

Perceptions of involuntary admission and risk of subsequent readmission at one-year follow-up: the influence of insight and recovery style.

BACKGROUND: Involuntary admission is one of the most ethically challenging practices in medicine, yet we are only beginning to learn more about the patient's perspective. AIMS: To investigate (i) peoples' perception of the necessity of their involuntary admission at one year after discharge (ii) readmission rates to hospital and the influence of insight and recovery style. METHODS: We interviewed individuals admitted involuntarily at one year following discharge using the Mac Arthur Admission Experience Interview, Birchwood Insight Scale, the Drug Attitude Inventory, Global Assessment of Functioning and the Recovery Style Questionnaire. RESULTS: Sixty-eight people (84%) were re-interviewed at one year and fewer (60%) reported that their involuntary admission had been necessary when compared to inception (72%). Of the 33% that changed their views, most reflected negatively on their involuntary admission. We found that insight was moderately associated with the acknowledgement that the involuntary admission was necessary. Within a year, 43% were readmitted to hospital and half of these admissions were involuntary. Individuals with a sealing over recovery style were at four times the risk of involuntary readmission. CONCLUSIONS: Peoples' perception of the necessity of their involuntary admissions is not stable over time and risk of involuntary readmission is associated with recovery style.

The global impact on mental health almost 2 years into the COVID-19 pandemic.

Approaching 2 years into a global pandemic, it is timely to reflect on how COVID-19 has impacted the mental health of the global population. With research continuing apace, a clearer picture should crystallise in time. COVID-19 has undoubtedly had some impact on population mental health, although the severity and duration of this impact remain less clear. The exceptional period of COVID-19 has provided a unique prism through which we can observe and consider societal mental health. This is a momentous time to be involved in mental health research as we strive to understand the mental health needs of the population and advocate for adequate resourcing to deliver quality mental healthcare in the post-pandemic period.

The role of key workers in improving physical health in first episode psychosis: A scoping review.

AIM: Studies have demonstrated that a majority of the decline in health status and functioning emerges during the first few years following the onset of psychosis. This knowledge led to the development of specialized early intervention services (EIS) targeting patients experiencing their first episode of psychosis (FEP). The central component of EIS is often assertive case management delivered by a multidisciplinary team, where an appointed key worker is responsible for coordinating treatment and delivering various psychosocial interventions to service users. The aim of this scoping review was to examine how key workers can enhance the physical health outcomes in people with FEP by addressing the factors associated with increased mortality in this population. METHODS: The scoping review framework comprised a five-stage process developed by Arksey and O'Malley. The search process was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS: A total of 27 studies conducted across 10 countries were analysed. These studies discussed the various ways in which key workers can mediate enhancements in the various factors contributing to the increased mortality rates in FEP patients. CONCLUSIONS: A broad range of key worker-mediated outcomes was identified, which were broadly classified into three themes: influences on lifestyle, influences on effects of psychosis and influences on organizational barriers. Our findings suggest that key workers primarily mediated the amelioration of psychosis-induced effects and the reduction of organizational barriers. Further trials of key worker interventions to enhance physical health outcomes in this cohort are warranted.

Involuntary admission from the patients' perspective.

BACKGROUND: Involuntary admission legislation and rates differ greatly throughout the European Union Member States. In Ireland, the Mental Health Act 2001 has introduced significant changes in the care for patients admitted involuntarily, including mental health tribunals that review the involuntary admission orders. AIMS: To investigate (1) people's perception of the involuntary admission, (2) awareness of legal rights and perception of tribunal, (3) the impact of being admitted involuntarily on the relationship with their family, consultant psychiatrist and prospects for future employment. METHODS: Over a 15-month period patients admitted involuntarily to a Dublin Hospital were interviewed using a semi structured interview. RESULTS: Eighty-one people participated in the study. Seventy-two percent of patients believed that their involuntary admission was necessary at the time and this was associated with greater insight into illness. A total of 77.8% of patients felt that the treatment they received had been beneficial. A total of 86.4% of patients were aware that they had been admitted involuntarily and 45.5% of patients found it easier to accept that they had been admitted involuntarily as their case was reviewed by a tribunal. A total of 27.5% experienced a negative impact upon the relationship with their family as a result of the involuntary admission, while for 15% there was a positive impact. For 26.6% of patients the doctor-patient relationship was negatively impacted upon and a third felt their prospects for employment could be affected. CONCLUSION: The majority of patients reflect positively on their involuntary admission and this opportunity should be used to engage patients in follow-up treatment.

Higher rates of disengagement among young adults attending a general adult community mental health team: Time to consider a youth-specific service?

AIM: The initial onset of mental illness occurs most frequently in adolescence or early adulthood. In order to inform the development of mental health services tailored for youth, we sought to compare the characteristics of young (18-25 years old) and older (over 25 years old) adults following referral to a general adult community mental health team. METHODS: All individuals referred to a Dublin-based community mental health team and offered an appointment between January 1 and December 31, 2016 were included in the study. Information in relation to engagement patterns, demographic characteristics and clinical characteristics was collected. RESULTS: A total of 298 appointments were offered during the study period among which 94 (31.6%) were for young adults. Significant differences in demographic and clinical characteristics between the two age groups were evident. Young adults were significantly less likely to have been prescribed psychotropic medication at the point of referral (63% vs. 82% respectively, χ2 = 12.30, p < .001). Older adults were four times more likely to demonstrate a good level of early engagement in treatment than young adults (AOR 4.00, 95% CI 1.11-14.37, p = .03). CONCLUSIONS: Young adults had distinct clinical needs and a lower level of engagement in the early stage of treatment compared with their older counterparts in this community team. Further research and stakeholder consultation is needed to more clearly identify the issues in relation to patient engagement. These insights will help to inform the development of youth-specific community mental health services.

Visible near infrared reflectance molecular chemical imaging of human ex vivo carcinomas and murine in vivo carcinomas.

SIGNIFICANCE: A key risk faced by oncological surgeons continues to be complete removal of tumor. Currently, there is no intraoperative imaging device to detect kidney tumors during excision. AIM: We are evaluating molecular chemical imaging (MCI) as a technology for real-time tumor detection and margin assessment during tumor removal surgeries. APPROACH: In exploratory studies, we evaluate visible near infrared (Vis-NIR) MCI for differentiating tumor from adjacent tissue in ex vivo human kidney specimens, and in anaesthetized mice with breast or lung tumor xenografts. Differentiation of tumor from nontumor tissues is made possible with diffuse reflectance spectroscopic signatures and hyperspectral imaging technology. Tumor detection is achieved by score image generation to localize the tumor, followed by application of computer vision algorithms to define tumor border. RESULTS: Performance of a partial least squares discriminant analysis (PLS-DA) model for kidney tumor in a 22-patient study is 0.96 for area under the receiver operating characteristic curve. A PLS-DA model for in vivo breast and lung tumor xenografts performs with 100% sensitivity, 83% specificity, and 89% accuracy. CONCLUSION: Detection of cancer in surgically resected human kidney tissues is demonstrated ex vivo with Vis-NIR MCI, and in vivo on mice with breast or lung xenografts.
