Inflammatory and blood gas markers of COVID-19 delirium compared to non-COVID-19 delirium: a cross-sectional study.

OBJECTIVES: We aimed to find the association of inflammation and respiratory failure with delirium in COVID-19 patients. We compare the inflammatory and arterial blood gas markers between patients with COVID-19 delirium and delirium in other medical disorders. METHODS: This cross-sectional study used the CHART-DEL, a validated research tool, to screen patients for delirium retrospectively from clinical notes. Inflammatory markers C-reactive protein (CRP) and white cell count (WBC), and the partial pressures of oxygen (PO2) and carbon dioxide (PCO2) were compared between patients with COVID-19 delirium and delirium in other medical disorders. RESULTS: In bivariate analysis, CRP (mg/L) was significantly higher in the COVID-19 group, (81.7 ± 80.0 vs. 58.8 ± 87.7, p = 0.04), and WBC (109/L) was significantly lower (7.44 ± 3.42 vs. 9.71 ± 5.45, p = 0.04). The geometric mean of CRP in the COVID-19 group was 140% higher in multiple linear regression (95% CI = 7-439%, p = 0.03) with age and sex as covariates. There were no significant differences in pO2 or pCO2 across groups. CONCLUSION: The association between higher CRP and COVID-19 in patients with delirium may suggest an inflammatory basis for delirium in COVID-19. Our findings may assist clinicians in establishing whether delirium is due to COVID-19, which may improve management and outcomes of infected patients.

Cognitive impairment and development of dementia in very late-onset schizophrenia-like psychosis: a systematic review.

OBJECTIVES: This study aimed to review the evidence base regarding cognitive impairment and the development of dementia in patients with very late-onset schizophrenia-like psychosis (VLOSLP). METHODS: We conducted a systematic literature search of PubMed, PsycINFO and Web of Science according to Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. Two reviewers independently screened records first by title and abstract and then by full text, resolving differences after each stage. Selected studies were assessed for quality using the GRADE system, and data on study design, participants, cognitive ability and rates of developing dementia were extracted and synthesised. RESULTS: Seventeen publications were identified for review. They were generally poor in quality and heterogenous in design. VLOSLP patients were found to have impaired global cognition compared to non-psychotic controls, but no difference was found between VLOSLP patients and aged early-onset schizophrenia (EOS) patients. No single cognitive domain was consistently affected. Patients with VLOSLP demonstrated significantly higher rates of dementia diagnosis (ranging from 4.4% over 3 years to 44.4% over 15 years) than controls, but no difference was found between VLOSLP patients and aged EOS patients. CONCLUSIONS: VLOSLP may not necessarily predict cognitive decline, but few studies have adequately investigated cohorts on a longitudinal basis. Heterogeneity between and within cohorts and varying selection criteria compromise the clinical generalisability of studies investigating the association between VLOSLP and neurodegenerative disease. Further studies on the clinical presentation, cognitive profile and neuropathology of VLOSLP with comparison to EOS/late-onset schizophrenia (LOS) and neurodegenerative disease are needed to better inform the diagnosis and management of VLOSLP.

Perspectives of GCSE students attending a psychiatry summer school in south London.

AIMS AND METHOD: This study evaluated a pilot psychiatry summer school for GCSE students in terms of participant experience, effects on attitudes to mental illness and perception of psychiatry as a career option. This was done using the Community Attitudes towards the Mentally Ill scale, career choice questionnaires and a discussion group following the week-long programme attended by 26 students. RESULTS: Students were significantly more likely to choose psychiatry after the summer school (P = 0.01). There were statistically significant changes in scores for social restrictiveness (P = 0.04) and community mental health ideology (P = 0.02). Qualitative analysis generated four themes: variation in expectations, limited prior knowledge, perception of the summer school itself and uniformly positive attitudes to psychiatry after the summer school. CLINICAL IMPLICATIONS: Targeting students at this early stage appears to be an underexplored positive intervention for improving both attitudes towards mental illness and recruitment to psychiatry.

Clozapine prescribing in COVID-19 positive medical inpatients: a case series.

There is both uncertainty regarding the safety of clozapine in COVID-19 patients owing to limited published data and a lack of consensus on continuing clozapine in patients with severe respiratory infections. COVID-19 is known to induce an acute immune response which can affect haematological parameters associated with clozapine monitoring, and systemic infection may reduce clozapine clearance. Clozapine, which has been associated with worse outcomes in some pneumonias, may in theory worsen outcomes in COVID-19. Despite these concerns, there are some data to indicate it is safe to continue clozapine in COVID-19 infection. In this retrospective case series, we describe our experiences of clozapine prescribing and disease progression of eight SARS-CoV-2 positive patients on medical wards in a major London teaching hospital. In four cases clozapine was stopped during the hospital admission. A COVID-19 pneumonia developed in four patients: three of these required intensive care unit admission for an average of 34 days. At the time of writing, three patients had died (two directly from COVID-19 pneumonia), two remained in general hospital wards, two were recovering in the community and one had been transferred to an inpatient psychiatric hospital. Follow-up length varied but in each case was not more than 104 days. Delirium was the most common adverse neuropsychiatric event, and in one case a relapse of psychosis occurred after cessation of clozapine. This retrospective case series illustrates the safe use of clozapine during COVID-19 infection. Our experiences suggest that consideration should be made to continuing clozapine even in those most unwell with COVID-19. We also identify areas which require larger scale hypothesis-testing research.

Prevalence of Burnout in Medical and Surgical Residents: A Meta-Analysis.

The burnout syndrome is characterized by emotional exhaustion, depersonalization, and reduced personal achievement. Uncertainty exists about the prevalence of burnout among medical and surgical residents. Associations between burnout and gender, age, specialty, and geographical location of training are unclear. In this meta-analysis, we aimed to quantitatively summarize the global prevalence rates of burnout among residents, by specialty and its contributing factors. We searched PubMed, PsycINFO, Embase, and Web of Science to identify studies that examined the prevalence of burnout among residents from various specialties and countries. The primary outcome assessed was the aggregate prevalence of burnout among all residents. The random effects model was used to calculate the aggregate prevalence, and heterogeneity was assessed by I2 statistic and Cochran's Q statistic. We also performed meta-regression and subgroup analysis. The aggregate prevalence of burnout was 51.0% (95% CI: 45.0-57.0%, I2 = 97%) in 22,778 residents. Meta-regression found that the mean age (ß = 0.34, 95% CI: 0.28-0.40, p < 0.001) and the proportion of males (ß = 0.4, 95% CI = 0.10-0.69, p = 0.009) were significant moderators. Subgroup analysis by specialty showed that radiology (77.16%, 95% CI: 5.99-99.45), neurology (71.93%, 95% CI: 65.78-77.39), and general surgery (58.39%, 95% CI: 45.72-70.04) were the top three specialties with the highest prevalence of burnout. In contrast, psychiatry (42.05%, 95% CI: 33.09-51.58), oncology (38.36%, 95% CI: 32.69-44.37), and family medicine (35.97%, 95% CI: 13.89-66.18) had the lowest prevalence of burnout. Subgroup analysis also found that the prevalence of burnout in several Asian countries was 57.18% (95% CI: 45.8-67.85); in several European countries it was 27.72% (95% CI: 17.4-41.11) and in North America it was 51.64% (46.96-56.28). Our findings suggest a high prevalence of burnout among medical and surgical residents. Older and male residents suffered more than their respective counterparts.

Service and treatment engagement of people with very late-onset schizophrenia-like psychosis.

Aims and method Electronic patient records were used to investigate the level of engagement and treatment that patients with very late-onset schizophrenia-like psychosis (VLOSLP) had with mental health services. Results Of 131 patients assessed and diagnosed, 63 (48%) were taking antipsychotic treatment at 3 months, 46 (35%) at 6 months and 36 (27%) at 12 months. At discharge from mental health services, 54% of patients had failed to engage with services or became lost to follow-up, 18% had engaged with services but were not taking antipsychotic medication and only 28% were taking treatment. Clinical implications Results showed that less than half of the patients with VLOSLP were commenced on antipsychotic treatment and less than a third remained on treatment at 1 year or at point of discharge. This highlights the need for services to consider being more assertive in taking potentially effective treatment to this patient group.

Reduction of referral to assessment time for an older adults community mental health team.

Anecdotal evidence suggested that waiting times within the older adults community mental health team (OA CMHT) had been increasing over time. An assessment and evaluation was indicated to ensure best quality care was provided for patients. A comparison was made between waiting times in January to December 2011 compared with August 2013 to July 2014. In 2011 the mean number of days until initial assessment from the point of referral was 12 days for routine cases, and 3.6 days for urgent cases. The re-audit showed the number of days increased to 15.89 days for routine cases, and 9.81 days for urgent cases. Contributory factors were reviewed, and it was felt that to address this problem, a duty worker role was necessary. The role of the duty worker was divided into triaging and allocating work. The triaging process was to ensure all urgent cases were highlighted early and acted upon. The duty worker's role was also to gather sufficient information from the referrer, to reduce the risks of inadequate knowledge delaying assessment. In addition, the allocating process required the duty worker to designate a clinician in charge of the case upon receipt of referral. This ensured that clinicians were able to offer the earliest possible appointment slot for the initial assessment, and thus reduce waiting times. Following implementation, findings from September 2014 to February 2015 showed an improvement in average waiting times, as well as an improvement in the percentage of assessments reviewed within previously set standards. For routine reviews, the mean time until assessment was 10.68 days. For urgent reviews, the mean time until initial assessment was 6.8 days. However, it was noted that majority of urgent reviews were still not being reviewed in time. The outcomes of this study demonstrated an improvement of both waiting times, and percentage of patients being seen within set standards following a single intervention. In the current climate of cost efficiency savings, it is important for services to continue to find ways to streamline and improve upon current practices, to ensure the best outcome for patients.
