Suicide mortality rates are a strong indicator of population mental-health and can be used to determine the efficacy of prevention measures. Monitoring suicide mortality rates in real-time provides an evidence-base to inform targeted interventions in a timely manner and accelerate suicide prevention responses. This paper outlines the importance of real-time suicide surveillance in the context of policy and practice, with a particular focus on public health and humanitarian crises.

Aims:
To compare Lithium prescribing practices in a Psychiatry of Old Age (POA) Service in the North-West ofIreland among adults aged 65 years and over with best practice guidelines.
Methods:Review of the literature informed development of audit standards for Lithium prescribing. These included National Institute for Clinical Excellent (NICE) 2014 guidelines, The British National Formulary(2019) and Maudsley Prescribing Guidelines (2018). Data was collected retrospectively, using an audit-specific data collection tool, from clinical files of POA team caseload, aged 65 years or more and prescribed Lithium over the past year.
Results:At the time of audit in February 2020, 18 patients were prescribed lithium, 67% female, average age 74.6 years. Of those prescribed Lithium; 50% (n=9) had depression, 44% (n=8) had bipolar affective disorder (BPAD) and 6% (n=1) schizoaffective disorder.
78% (n= 14) of patients met the NICE standard of 3-monthly lithium level. Lithium levels were checkedon average 4.5 times in past year, average lithium level was 0.61mmol/L across the group and 39% (n=7) had lithium level within recommended therapeutic range (0.6-0.8mmol/L).
83% of patients (n=15) met the NICE standards of 3 monthly renal tests. Taking into consideration mostrecent blood test results, 100% (n=18) had abnormal renal function.
Half (n=9) were initiated on lithium by POA service and of these, 56% (n=5) had documented renal impairment prior to initiation. Of patients on long term lithium at time of referral (n=9), almost half (n=4) had a documented history of lithium toxicity.
Conclusions:The results of this audit highlight room for improvement in lithium monitoring of older adults attending POA service. Furthermore, all patients prescribed lithium had impaired renal function. This is an important finding given the associations between those admitted to hospital with COVID-19 and co- morbid kidney disease and increased risk of inpatient death.
Our findings highlight the need for three monthly renal function monitoring in elderly prescribed lithiumgiven the additive adverse effects of increasing age and lithium on the kidney. Close working with specialised renal services to provide timely advice on renal management for those with renal impairment prescribed lithium is important to minimise adverse patient outcomes.

INTRODUCTION:
Lithium has a narrow therapeutic index with a risk of toxicity and potential to increase morbidity and mortality, particularly in the elderly with co-morbid illness and polypharmacy. Lithium therapy and monitoring of lithium levels require precision and several guidelines have been issued including recommendations for strict control of lithium levels in the elderly population.
RESEARCH OBJECTIVE:We evaluated the effect of implementation of a multifaceted management programme on the compliance with international practice standards for lithium monitoring in patients under the care of Psychiatry of Old Age (POA), Sligo Leitrim Mental Health Services in the North West of Ireland.
METHODS:Results from a prior audit performed in February 2020 involving a cohort of 18 patients prescribed lithium under the care of POA were analysed and compared to accepted standards. The guideline used as the benchmark for compliance was the National Institute for Clinical Excellence (NICE) guidelines on the use and monitoring of lithium therapy, as published in 2014. Several deficits were found and therefore a designated Lithium Management Programme was established. A subsequent audit, performed using a simplified audit tool incorporating the NICE guidelines, delivered results which were directly compared to the initial findings and analysed to evaluate the effect of the implemented management programme.
PRELIMINARY RESULTS OF THE ONGOING STUDY:In comparison with findings from 2020, there had been a significant improvement in most facets of lithium management and compliance to practice standards. Of particular note was the improvement of biochemical monitoring, side effect screening, polypharmacy surveillance, patient education and interdisciplinary communication.
CONCLUSION:The launch of a dedicated Lithium Management Programme with specific features aimed at identifying and addressing poor compliance with monitoring guidelines has led to improved adherence to accepted international practice standards. Our model provides a dynamic, multi-layered system which paves the way for better patient outcomes, timely access to care and furthering education for patients and staff members.

Objective:
To examine whether usual beverage intake was associated with sleep timing, duration and fragmentation among adolescents.
Design:Usual beverage intake was assessed with a FFQ. Outcomes included sleep duration, midpoint (median of bed and wake times) and fragmentation, assessed with 7-d actigraphy. Sex-stratified linear regression was conducted with sleep characteristics as separate outcomes and quantiles of energy-adjusted beverage intake as exposures, accounting for age, maternal education, physical activity and smoking.
Setting:Mexico City.
Participants:528 adolescents residing in Mexico City enrolled in a longitudinal cohort.
Results:The mean age (sd) was 14·4 (2·1) years; 48 % were male. Among males, milk and water consumption were associated with longer weekday sleep duration (25 (95 % CI 1, 48) and 26 (95 % CI 4, 47) more minutes, in the 4th compared to the 1st quartile); and higher 100 % fruit juice consumption was related to earlier weekday sleep timing (−22 (95 % CI −28, 1) minutes in the 1st compared to the last quantile; P = 0·03). Among females, soda was associated with higher sleep fragmentation (1·6 (95 % CI 0·4, 2·8) % in the 4th compared to the 1st), and coffee/tea consumption was related to shorter weekend sleep duration (−23 (95 % CI −44, 2) minutes in the 4th compared to the 1st).
Conclusions:Among females, adverse associations with sleep were observed for caffeinated drinks, while males with higher consumption of healthier beverage options (water, milk and 100 % juice) had evidence of longer and earlier-timed sleep. Potential mechanisms involving melatonin and tryptophan should be further investigated.

Background.
Abnormalities in the semantic and syntactic organization of speech have been reported in individuals at clinical high-risk (CHR) for psychosis. The current study seeks to examine whether such abnormalities are associated with changes in brain structure and functional connectivity in CHR individuals.
Methods.Automated natural language processing analysis was applied to speech samples obtained from 46 CHR and 22 healthy individuals. Brain structural and resting-state functional imaging data were also acquired from all participants. Sparse canonical correlation analysis (sCCA) was used to ascertain patterns of covariation between linguistic features, clinical symptoms, and measures of brain morphometry and functional connectivity related to the language network.
Results.In CHR individuals, we found a significant mode of covariation between linguistic and clinical features (r = 0.73; p = 0.003), with negative symptoms and bizarre thinking covarying mostly with measures of syntactic complexity. In the entire sample, separate sCCAs identified a single mode of covariation linking linguistic features with brain morphometry (r = 0.65; p = 0.05) and resting-state network connectivity (r = 0.63; p = 0.01). In both models, semantic and syntactic features covaried with brain structural and functional connectivity measures of the language network. However, the contribution of diagnosis to both models was negligible.
Conclusions.Syntactic complexity appeared sensitive to prodromal symptoms in CHR individuals while the patterns of brain-language covariation seemed preserved. Further studies in larger samples are required to establish the reproducibility of these findings.

Introduction
Peer relationships play a critical role in the development of adolescents, not only for the acquisition of social skills but also for the sense of personal identity and competence. Thus the quality of peer relationships influences actual and future mental health of the adolescent.
ObjectivesSEYLE (Saving and Empowering Young Lives in Europe) is a randomized controlled trial, funded by the EU, evaluating interventions for mental health promotion and suicide prevention. The study comprised 12,395 high-school students from 11 European countries.
AimsWe investigated the differences on psychological problems between students with poor and good peer relationships.
Methods1,195 adolescents (mean age 15.3 ± 0.6; 68% females) from the Molise region constituted the Italian sample. Adolescents were identified as with poor peer relationships if they never or just sometimes get along with people of their age, feel that peers like having them in the group and feel that peers were kind and helpful. Psychometric measures were used to assess mental health problems such as depression (Beck Depression Inventory II), anxiety (Zung Self-Assessment Anxiety Scale), well-being (WHO-5) and suicidal ideation (Paykel Suicide Scale).
ResultsAdolescents who reported poor peer relationships scored significantly higher (p < .005) on the scales assessing depression, anxiety and suicidal ideation and significantly lower (p < .001) on the WHO-5.
ConclusionsParticularly in adolescence peer relationships may influence psychological well-being and vice versa mental health influences the openness to the others. So promoting mental health and contemporary improve social skills could lead adolescents to a better life.

Background
Smoking among adolescents is still a major public health problem and a global concern. Early onset and long-term smoking are associated with physical and psychological health problems.
ObjectiveTo identify risk factors and comorbidities for occasional and daily smoking among European adolescents.
MethodsIn the context of the Europe-wide 'Saving and Empowering Young Lives in Europe” (SEYLE) study we surveyed 12,328 youths at the age of 13 to 17 from 11 countries. We applied questions from the Global School-Based Student Health Survey to determine nicotine consumption as well as other risk behaviors. Psychiatric symptoms were assessed by the Strengths and Difficulties Questionnaire, the Becks Depression Inventory-II, the Zung Self-Rating Anxiety Scale,the Deliberate Self-Harm Inventory and the Paykel Suicide Scale.
ResultsOn average 30.9% of adolescents reported daily smoking and the onset of smoking was reported by 35.3% between the age of 12 and 13 already. Multinomial logistic regression model showed significant correlations between adolescent smoking and migration background, living in single parent households, no physical activity, parental smoking and physical fights. Further it revealed significant associations of adolescent smoking with alcohol consumption, illegal drug use, anxiety, conduct problems, hyperactivity, suicidal ideation, self-injury and internet-dependence.
ConclusionOur data show that adolescent smoking is associated with psychosocial factors, especially family setting and parental behaviors. Further, smoking and psychiatric problems are highly correlated. Therefore, early preventive measures are necessary and essential not only for adolescents but also for their parents.

Background:
According to previous studies the prevalence of adolescent depression is 4–8% both in the USA and Europe. the aim of the current study was to investigate the prevalence of adolescent depression separately in several European countries.
Method:Data were drawn from the Saving and Empowering Young Lives in Europe (SEYLE) study, which included 11 countries (Austria, Estonia, France, Germany, Hungary, Ireland, Italy, Israel, Romania, Slovenia and Spain) and Sweden served as the coordinating centre. Depression was measured by the Beck Depression Inventory-II (BDI-II). Adolescents with a score of 20 or greater on the BDI-II were defined as depressed. Multiple imputations were conducted to address missing data.
Results:Out of 14,115 students who consented to participate, finally 12,395 adolescents (5,568 (44.92%) boys and 6,827 (55.08%) girls) were enrolled into the study. the mean age of the students was 14.81 years (SD = .83). Significant differences were detected in the ratio of non-depressed and depressed adolescents among countries (χ2(20) = 385.352 p = .000). the prevalence of depressed adolescents ranged from 7.1% to 19.4%. the prevalence of depressed adolescents according to country in increasing order is: Hungary: 7.1%, Austria: 7.6%, Romania: 7.6%, Estonia: 7.9%, Ireland: 8.5%, Spain: 8.6%, Italy: 9.2%, Slovenia: 11.4%, Germany: 12.9%, France: 15.4%, Israel: 19.4%.
Conclusion:Based on a screening tool our data underlines the importance of taking account country specific prevalence rates of adolescent depression.

Background
DSM-5 proposes an Attenuated Psychosis Syndrome (APS) for further investigation, based upon the Attenuated Positive Symptom Syndrome (APSS) in the Structured Interview for Psychosis-Risk Syndromes (SIPS). SIPS Unusual Thought Content, Disorganized Communication and Total Disorganization scores predicted progression to psychosis in a 2015 NAPLS-2 Consortium report. We sought to independently replicate this in a large single-site high-risk cohort, and identify baseline demographic and clinical predictors beyond current APS/APSS criteria.
MethodWe prospectively studied 200 participants meeting criteria for both the SIPS APSS and DSM-5 APS. SIPS scores, demographics, family history of psychosis, DSM Axis-I diagnoses, schizotypy, and social and role functioning were assessed at baseline, with follow-up every 3 months for 2 years.
ResultsThe conversion rate was 30% (n = 60), or 37.7% excluding participants who were followed under 2 years. This rate was stable across time. Conversion time averaged 7.97 months for 60% who developed schizophrenia and 15.68 for other psychoses. Mean conversion age was 20.3 for males and 23.5 for females. Attenuated odd ideas and thought disorder appear to be the positive symptoms which best predict psychosis in a logistic regression. Total negative symptom score, Asian/Pacific Islander and Black/African-American race were also predictive. As no Axis-I diagnosis or schizotypy predicted conversion, the APS is supported as a distinct syndrome. In addition, cannabis use disorder did not increase risk of conversion to psychosis.
ConclusionsNAPLS SIPS findings were replicated while controlling for clinical and demographic factors, strongly supporting the validity of the SIPS APSS and DSM-5 APS diagnosis.

Eta Carinae is one of the most massive observable binaries. Yet determination of its orbital and physical parameters is hampered by obscuring winds. However the effects of the strong, colliding winds changes with phase due to the high orbital eccentricity. We wanted to improve measures of the orbital parameters and to determine the mechanisms that produce the relatively brief, phase-locked minimum as detected throughout the electromagnetic spectrum. We conducted intense monitoring of the He ii λ4686 line in η Carinae for 10 months in the year 2014, gathering ~300 high S/N spectra with ground- and space-based telescopes. We also used published spectra at the FOS4 SE polar region of the Homunculus, which views the minimum from a different direction. We used a model in which the He ii λ4686 emission is produced by two mechanisms: a) one linked to the intensity of the wind-wind collision which occurs along the whole orbit and is proportional to the inverse square of the separation between the companion stars; and b) the other produced by the ‘bore hole’ effect which occurs at phases across the periastron passage. The opacity (computed from 3D SPH simulations) as convolved with the emission reproduces the behavior of equivalent widths both for direct and reflected light. Our main results are: a) a demonstration that the He ii λ4686 light curve is exquisitely repeatable from cycle to cycle, contrary to previous claims for large changes; b) an accurate determination of the longitude of periastron, indicating that the secondary star is ‘behind’ the primary at periastron, a dispute extended over the past decade; c) a determination of the time of periastron passage, at ~4 days after the onset of the deep light curve minimum; and d) show that the minimum is simultaneous for observers at different lines of sight, indicating that it is not caused by an eclipse of the secondary star, but rather by the immersion of the wind-wind collision interior to the inner wind of the primary.

In October 2012, an outbreak of gentamicin-resistant, ciprofloxacin non-susceptible extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae occurred in a neonatal intensive care unit in Ireland. In order to determine whether the outbreak strain was more widely dispersed in the country, 137 isolates of K. pneumoniae with this resistance phenotype collected from 17 hospitals throughout Ireland between January 2011 and July 2013 were examined. ESBL production was confirmed phenotypically and all isolates were screened for susceptibility to 19 antimicrobial agents and for the presence of genes encoding blaTEM, blaSHV, blaOXA, and blaCTX-M; 22 isolates were also screened for blaKPC, blaNDM, blaVIM, blaIMP and blaOXA-48 genes. All isolates harboured blaSHV and blaCTX-M and were resistant to ciprofloxacin, gentamicin, nalidixic acid, amoxicillin-clavulanate, and cefpodoxime; 15 were resistant to ertapenem, seven to meropenem and five isolates were confirmed as carbapenemase producers. Pulsed-field gel electrophoresis of all isolates identified 16 major clusters, with two clusters comprising 61% of the entire collection. Multilocus sequence typing of a subset of these isolates identified a novel type, ST1236, a single locus variant of ST48. Data suggest that two major clonal groups, ST1236/ST48 (CG43) and ST15/ST14 (CG15) have been circulating in Ireland since at least January 2011.

Background.
Schizophrenia is characterized by profound and disabling deficits in the ability to recognize emotion in facial expression and tone of voice. Although these deficits are well documented in established schizophrenia using recently validated tasks, their predictive utility in at-risk populations has not been formally evaluated.
Method.The Penn Emotion Recognition and Discrimination tasks, and recently developed measures of auditory emotion recognition, were administered to 49 clinical high-risk subjects prospectively followed for 2 years for schizophrenia outcome, and 31 healthy controls, and a developmental cohort of 43 individuals aged 7–26 years. Deficit in emotion recognition in at-risk subjects was compared with deficit in established schizophrenia, and with normal neurocognitive growth curves from childhood to early adulthood.
Results.Deficits in emotion recognition significantly distinguished at-risk patients who transitioned to schizophrenia. By contrast, more general neurocognitive measures, such as attention vigilance or processing speed, were non-predictive. The best classification model for schizophrenia onset included both face emotion processing and negative symptoms, with accuracy of 96%, and area under the receiver-operating characteristic curve of 0.99. In a parallel developmental study, emotion recognition abilities were found to reach maturity prior to traditional age of risk for schizophrenia, suggesting they may serve as objective markers of early developmental insult.
Conclusions.Profound deficits in emotion recognition exist in at-risk patients prior to schizophrenia onset. They may serve as an index of early developmental insult, and represent an effective target for early identification and remediation. Future studies investigating emotion recognition deficits at both mechanistic and predictive levels are strongly encouraged.

We investigate the physical properties of large-scale wind structures around massive hot stars with radiatively-driven winds. We observe Discrete Absorption Components (DACs) in optical He i P Cygni lines of the LBV binary MWC 314 (Porb = 60.8 d). The DACs are observed during orbital phases when the primary is in front of the secondary star. They appear at wind velocities between −100 km s−1 and −600 km s−1 in the P Cyg profiles of Hei λ5875, λ6678, and λ4471, signaling high-temperature expanding wind regions of enhanced density and variable outflow velocity. The DACs can result from wave propagation linked to the orbital motion near the low-velocity wind base. The He i lines indicate DAC formation close to the primary's surface in high-temperature wind regions in front of its orbit, or in dynamical wind regions confined between the binary stars. We observed the DACs with Mercator-HERMES on 5 Sep 2009, 5 May 2012, and 6 May 2014 when the primary is in front of the secondary star. XMM-Newton observations of 6 May 2014 significantly detected MWC 314 in X-rays at an average rate of ~0.015 cts s−1.

Background
Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase the risk of psychotic disorder in adulthood. There has been a lack of research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence.
AimsTo investigate the relationship between psychotic symptoms and non-psychotic psychopathology in community samples of adolescents in terms of prevalence, co-occurring disorders, comorbid (multiple) psychopathology and variation across early v. middle adolescence.
MethodData from four population studies were used: two early adolescence studies (ages 11–13 years) and two mid-adolescence studies (ages 13–16 years). Studies 1 and 2 involved school-based surveys of 2243 children aged 11–16 years for psychotic symptoms and for emotional and behavioural symptoms of psychopathology. Studies 3 and 4 involved in-depth diagnostic interview assessments of psychotic symptoms and lifetime psychiatric disorders in community samples of 423 children aged 11–15 years.
ResultsYounger adolescents had a higher prevalence (21–23%) of psychotic symptoms than older adolescents (7%). In both age groups the majority of adolescents who reported psychotic symptoms had at least one diagnosable non-psychotic psychiatric disorder, although associations with psychopathology increased with age: nearly 80% of the mid-adolescence sample who reported psychotic symptoms had at least one diagnosis, compared with 57% of the early adolescence sample. Adolescents who reported psychotic symptoms were at particularly high risk of having multiple co-occurring diagnoses.
ConclusionsPsychotic symptoms are important risk markers for a wide range of non-psychotic psychopathological disorders, in particular for severe psychopathology characterised by multiple co-occurring diagnoses. These symptoms should be carefully assessed in all patients.

Background: Several observational studies have suggested a link between health status and rate of decline among individuals with Alzheimer's disease (AD). We sought to quantify the relationship in a population-based study of incident AD, and to compare global comorbidity ratings to counts of comorbid conditions and medications as predictors of AD progression.
Methods: This was a case-only cohort study arising from a population-based longitudinal study of memory and aging, in Cache County, Utah. Participants comprised 335 individuals with incident AD followed for up to 11 years. Patient descriptors included sex, age, education, dementia duration at baseline, and APOE genotype. Measures of health status made at each visit included the General Medical Health Rating (GMHR), number of comorbid medical conditions, and number of non-psychiatric medications. Dementia outcomes included the Mini-Mental State Examination (MMSE), Clinical Dementia Rating – sum of boxes (CDR-sb), and the Neuropsychiatric Inventory (NPI).
Results: Health status tended to fluctuate over time within individuals. None of the baseline medical variables (GMHR, comorbidities, and non-psychiatric medications) was associated with differences in rates of decline in longitudinal linear mixed effects models. Over time, low GMHR ratings, but not comorbidities or medications, were associated with poorer outcomes (MMSE: β = –1.07 p = 0.01; CDR-sb: β = 1.79 p < 0.001; NPI: β = 4.57 p = 0.01).
Conclusions: Given that time-varying GMHR, but not baseline GMHR, was associated with the outcomes, it seems likely that there is a dynamic relationship between medical and cognitive health. GMHR is a more sensitive measure of health than simple counts of comorbidities or medications. Since health status is a potentially modifiable risk factor, further study is warranted.

Background
Increased sensitivity and exposure to stress are associated with psychotic symptoms in schizophrenia and its risk states, but little is known about the co-evolution of stress sensitivity and exposure with positive and other symptoms in a clinical high-risk (CHR) cohort.
MethodA combined cross-sectional and longitudinal design was used to examine the associations over time of stress sensitivity and exposure (i.e. life events) with ‘prodromal’ symptoms in a cohort of 65 CHR patients assessed quarterly for up to 4 years, and at baseline in 24 healthy controls similar in age and gender.
ResultsImpaired stress tolerance was greater in patients, in whom it was associated over time with positive and negative symptoms, in addition to depression, anxiety and poor function. By contrast, life events were comparable in patients and controls, and bore no association with symptoms. In this treated cohort, there was a trajectory of improvement in stress tolerance, symptoms and function over time.
ConclusionsImpaired stress tolerance was associated with a wide range of ‘prodromal’ symptoms, consistent with it being a core feature of the psychosis risk state. Self-reported life events were not relevant as a correlate of clinical status. As in other treated CHR cohorts, most patients improved over time across symptom domains.

Sporozoites of P. falciparum and other Plasmodia appear to be fairly simple antigenically, in that there is a dominant antigen, the circumsporozoite (CS) protein that forms the sporozoite surface coat (Potocnjak, Yoshida, Nussenzweig & Nussensweig, 1980; Santoro et al. 1983). Consequently, the CS protein and the gene encoding it have now been studied in considerable detail (Ellis et al. 1983; Godson et al. 1983; Ozaki et al. 1983; Dame et al. 1984; Enea et al. 1984). In contrast to sporozoites, the asexual blood stages of P. falciparum are antigenically complex. Two-dimensional gel analyses of immunoprecipitated, biosynthetically labelled antigens indicate that repeated infection with P. falciparum results in the synthesis of antibodies against a large number of distinct antigens (Perrin & Dayal, 1982; Brown et al. 1981, 1983). In further contrast to the sporozoite, the asexual blood stages of different P. falciparum isolates exhibit a high degree of antigenic heterogeneity (Brown et al. 1983; Hall et al. 1983; McBride, Walliker & Morgan, 1982). Much of this antigenic diversity is no doubt due to allelic differences but clonal populations of parasites may also have the capacity to undergo antigenic variation (Hommel, David & Oligino, 1983).

Background
Social dysfunction is a hallmark symptom of schizophrenia which commonly precedes the onset of psychosis. It is unclear if social symptoms in clinical high-risk patients reflect depressive symptoms or are a manifestation of negative symptoms.
MethodWe compared social function scores on the Social Adjustment Scale-Self Report between 56 young people (aged 13–27 years) at clinical high risk for psychosis and 22 healthy controls. The cases were also assessed for depressive and ‘prodromal’ symptoms (subthreshold positive, negative, disorganized and general symptoms).
ResultsPoor social function was related to both depressive and negative symptoms, as well as to disorganized and general symptoms. The symptoms were highly intercorrelated but linear regression analysis demonstrated that poor social function was primarily explained by negative symptoms within this cohort, particularly in ethnic minority patients.
ConclusionsAlthough this study demonstrated a relationship between social dysfunction and depressive symptoms in clinical high-risk cases, this association was primarily explained by the relationship of each of these to negative symptoms. In individuals at heightened risk for psychosis, affective changes may be related to a progressive decrease in social interaction and loss of reinforcement of social behaviors. These findings have relevance for potential treatment strategies for social dysfunction in schizophrenia and its risk states and predict that antidepressant drugs, cognitive behavioral therapy and/or social skills training may be effective.

Objectives: This study examined and compared the number and pattern of referrals from neurosurgery and neurology specialist services to the inpatient liaison neuropsychiatry service in the years 2002 and 2005. We estimated the prevalence of psychiatric illness and evaluated the results of subsequent psychiatric assessment and follow-up of all patients reviewed by the neuropsychiatry service.
Methods: The medical notes of those patients referred to the neuropsychiatry team were retrospectively examined to obtain appropriate information on assessment and management of these cases.
Results: There were 544 referrals over the two years selected for study. Rates of referral to the inpatient neuropsychiatry service increased overall by 35% between 2002 and 2005. Overall, referrals from neurology comprised 85%, neurosurgery 15%. Patients with epilepsy comprised the majority of referrals (36%). A total of 378 (73%) had an acute psychiatric disorder and this group had a significantly higher rate (p = 0.01) of past psychiatric disorder (40%) than that in those with no acute mental illness (33%). Depressive episode was the most frequent acute psychiatric diagnosis (38%), followed by anxiety and organic psychiatric disorder (both 15%). Overall, 21% of patients diagnosed with acute mental illness were referred on discharge to the neuropsychiatry outpatient clinic for specialist follow up and the remainder followed-up by either local mental health teams or their GP.
Conclusions: These findings provide clear evidence that further resources should be allocated to expanding neuropsychiatry mental health services to improve detection and management of mental illness in this vulnerable patient group.
