Reduced Activity in an Inpatient Liaison Psychiatry Service During the First Wave of the COVID-19 Pandemic: Comparison With 2019 Data and Characterization of the SARS-CoV-2 Positive Cohort

Police-referred psychiatric emergency presentations during the first and second wave of COVID-19 in Berlin, Germany: a retrospective chart review

BACKGROUND

Literature on psychiatric emergency services (PES) presentations during the COVID-19 pandemic showed heterogeneous results regarding patients brought in by police (BIBP). This is the first study primarily focusing on patients BIBP in a PES during the COVID-19-period.

METHODS

Case documentation records during the first and second wave of the COVID-19 pandemic in a PES in Berlin, Germany were analyzed using descriptive data analysis and binomial logistic regression analysis to detect factors that predict presentations BIBP.

RESULTS

5440 PES presentations: 20.4% BIBP during the first wave vs. 16.3% during its control period; second wave: 17.6% BIBP vs. 14.9% during its control period. In both waves, absolute increases in presentations BIBP were seen compared to control (p = .029, p = .028, respectively). COVID-19-period was a predictor for presentations BIBP during the first and the second wave. The following factors also predicted presentations BIBP: younger age, male gender, aggressive behavior, suicide attempt prior to presentation and diagnosis of psychotic or substance use disorders; depressive disorders were negatively associated.

CONCLUSIONS

During the two first waves of the COVID-19 pandemic, there was an increase in presentations BIBP in a PES in Berlin. Regression analysis shows that the pandemic itself was a predictor of presentations BIBP. The underlying factors of this association need to be further elucidated in future research. Additionally, general factors predicting PES presentations BIBP are reported that replenish the present literature.

First-Onset Psychosis After COVID-19 Infection: A Systematic Review of the Literature

BACKGROUND

The COVID-19 pandemic has been an inciting factor for a wide variety of neuropsychiatric symptoms, including first-episode psychosis (FEP).

OBJECTIVE

The aim of this systematic review was to summarize the current literature on COVID-19 associated postviral FEP.

METHODS

A systematic review was completed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and identified 81 articles that met inclusion criteria.

RESULTS

Articles included case reports, case series, and cohort studies with postviral FEP occurring outside the setting of delirium, demonstrating a broad range of symptoms.

CONCLUSIONS

This systematic review shows that postviral FEP associated with COVID-19 follows a pattern similar to psychosis associated with other viral infections and is an important consideration when building a differential for FEP when delirium has been ruled out. Better understanding of postviral FEP associated with COVID-19 and other viral illnesses may help clarify aspects of underlying pathophysiology of psychotic symptoms broadly.

Increase in presentations with new-onset psychiatric disorders in a psychiatric emergency department in Berlin, Germany during the second wave of the COVID-19 pandemic - a retrospective cross-sectional study

Introduction

While numerous studies have identified an increase in symptoms of depression as well as anxiety and distress due to the COVID-19 pandemic, relatively few studies have investigated the new-onset of psychiatric diseases during the pandemic.

Methods

This study focuses on the number of psychiatric new-onset diagnoses in a psychiatric emergency department (pED) in Berlin, Germany during the second wave of the pandemic (i.e. from 09/15/2020 to 03/01/2021 = COVID-19-period) compared to pre-pandemic times (09/15/2019 to 03/01/2020 = control period). We focused on diagnostic subgroups and performed logistic regression analysis to investigate potential risk groups based on covariables such as age, gender, homelessness, attending in police custody and familial relationship.

Results

Overall, there was a 59.7% increase in new-onset psychiatric diagnoses during the COVID-19-period. Increases in the following diagnoses were observed: new-onset of substance-related and addictive disorders (+192.5%), depressive disorders (+115.8%), schizophrenia spectrum and psychotic disorders (+113.3%) and anxiety disorders (+63.6%). These diagnostic subgroups, together with attending in police custody, were found to predict pED presentations with new-onset during the COVID-19-period. Interestingly, in the group of new-onset psychiatric diseases in the COVID-19-period, higher amounts of job loss and living alone as well as a relative decrease in familial relationships were observed.

Discussion

COVID-19 infections and post-COVID-19 syndrome are unlikely to have played a substantial role in the increase of new-onset diseases in this study. Conclusion: Our findings underline the role of indirect factors in new-onset of psychiatric diseases during the pandemic and should be a caveat for future pandemic control policies.

The impact of the second wave of COVID-19 on liaison psychiatry: a comparative retrospective study with the homologous non-pandemic period

OBJECTIVE

To determine the impact of COVID-19 pandemic (COVID-19-P) on clinical and health organisational variables of patients evaluated by Liaison Psychiatry (LP).

METHODS

Revision of all collaboration requests (CR) to LP for patients hospitalised in a Portuguese General Hospital during the second wave of COVID-19-P, from 1 October to 31 December of 2020. Medical charts were analysed and selected variables were compared with those of the homologous non-pandemic period. Data were statistically analysed.

RESULTS

There was a 22.3% decrease in the number of CR in 2020. The most frequently given reasons for CR were depressive symptoms, psychomotor agitation, and difficulties in adapting to the disease in both years. However, 5.9% more patients reported suicidal ideation in 2020. The hospitalisation length before CR was smaller in 2020 than in 2019 (9 vs 11). There was a higher proportion of patients followed in a psychiatric consultation and previously taking psychotropic medication before hospitalisation in 2020 than in 2019. After the assessment, the trend was that both groups did not meet diagnostic criteria for any disorder and no pharmacological adjustment was needed.

CONCLUSION

This study highlights the need to better characterise the indirect repercussion of COVID-19-P, and focus on the prevention and treatment of mental illness particularly in adverse contexts.Key PointsFewer collaboration requests to liaison psychiatry during the second wave of COVID-19;Collaboration requests were made earlier in the hospitalisation;For patients with more medical comorbidities, psychiatric history, and psychotropic medication;Most because of depressive symptoms and more with suicidal ideation;Fewer collaboration requests to liaison psychiatry during COVID-19;Made earlier in the hospitalisation;For patients with more medical comorbidities, psychiatric history, and medication;Most because of depressive symptoms and more with suicidal ideation.

Psychiatric ward admissions during the COVID-19 pandemic in Canton of Ticino (Swiss Confederation) and the province of Como (Italy): a comparison between two different systems of care and outbreak response strategies

The aim of the study was to estimate the effect of the COVID- 19 pandemic and response policies on the psychiatric ward admissions in the hospitals referring to the ASST Lariana (province of Como, Italy) and the Hospital of Mendrisio (Canton of Ticino, Switzerland), two similar territories that belong to countries that dealt differently with the pandemic. We compared the two territories for type of admission (voluntary vs. compulsory), the Stringency Index (SI) and the country’s number of admission in Intensive Care Units (ICU). We found a significant reduction in the psychiatric ward admission in the lockdown period in both territories, even in periods with milder lockdown measures. The admission rate’s reduction in the ASST Lariana was significantly associated with the ICU admissions (p<0.001). In the Hospital of Mendrisio, admissions included a weekly seasonality, were significantly correlated with SI (p=0.001) and period (pre-pandemic and pandemic; p<0.001) and we observed also a significant reduction of compulsory admission that is influenced both by the stringency index (p<0.001) and period (p<0.001). The differences between the two territories seem influenced by the different mental health systems.

Psychiatric presentations and admissions during the first wave of Covid-19 compared to 2019 in a psychiatric emergency department in Berlin, Germany: a retrospective chart review

BACKGROUND

Most studies agree that the Covid-19 pandemic and the subsequent lockdown had a negative impact on mental health. On the other hand, international studies have shown that psychiatric emergency departments (pED) experienced a decrease in presentations and admissions.

METHODS

Retrospective chart review of all pED presentations and admissions during the first wave of Covid-19 pandemic in Germany (Covid-19 period: 3/2/20 to 05/24/20) in a psychiatric hospital in Berlin compared to 1 year earlier (pre-Covid-19 period). Descriptive statistics and logistic regression were performed.

RESULTS

We observed no statistical significant changes in overall pED presentations and overall hospital admissions during the Covid-19 period compared to the pre-Covid-19 period (813 vs. 894, - 9.1%, p = 0.064 and (363 vs. 437, - 16.9%, p = 0.080 respectively). In the subgroup analysis, less patients with depressive disorders (p = 0.035) and with personality disorders (p = 0.002) presented to the pED, a larger number of presentations with schizophrenia was observed (p = 0.020). In the Covid-19 period, less patients with substance use disorder and paranoid schizophrenia were admitted to the hospital via the pED than in the pre-Covid-19 period (p = 0.035 and p = 0.006, respectively). Bed capacity was reduced in the Covid-19 period by - 32.8% (p <  0.001). Presentations in police custody were 13.7% (p = 0.029) higher during the Covid-19 compared to pre-Covid-19 period, with higher rates in female presentations (p = 0.008) and suicide attempts (p = 0.012) and less hospital admissions (p = 0.048). Logistic regression analyses revealed that positive predictors for pED presentation during Covid-19 period were police custody (p <  0.001), being redirected from another hospital (p <  0.001), suicide attempt (p = 0.038), suicidal thoughts (p = 0.004), presentation with paranoid schizophrenia (p = 0.001) and bipolar and manic disorders (p = 0.004), negative predictors were hospital admission (p <  0.001), depressive disorders (p = 0.021) and personality disorders (p <  0.001).

CONCLUSIONS

A larger number of presentations in police custody during the Covid-19 period may represent untreated medical needs. This was seen predominantly in female patients, suggesting this subgroup might have suffered particularly under lockdown measures. Patients with paranoid schizophrenia were the only subgroup, which increased in absolute numbers, also suggesting a particular lockdown effect. Reduced bed capacity due to infection curbing measures is suggestive to have played an important role in augmenting the threshold for hospital admissions.

Suicidality in psychiatric emergency department situations during the first and the second wave of COVID-19 pandemic

Psychiatric patients are prone to mental health deterioration during the Covid-19 pandemic. Little is known about suicidality in psychiatric patients during the Covid-19 pandemic. This study is a retrospective chart review of psychiatric emergency department (pED) presentations with present or absent suicidality (5634 pED attendances, 4110 patients) in an academic pED in Berlin, Germany. Poisson regression analysis was performed on the effect of Covid-19 period on suicidality (suicidal ideation (SI), suicide plans (SP) or suicide attempt (SA)) during the first (3/2/2020-5/24/2020 "first-wave") and second (9/15/2020-3/1/2021 "second-wave") wave of the Covid-19 pandemic compared to the same periods one year earlier. During the first-wave the number of pED visits per person with SI, SP and SA was higher compared to one year earlier (SI RR = 1.614; p = 0.016; SP RR = 2.900; p = 0.004; SA RR = 9.862; p = 0.003). SI and SP were predicted by interaction between substance use disorder (SUD) and second-wave (SI RR = 1.305, p = 0.043; SP RR = 1.645, p = 0.018), SA was predicted by interaction between borderline personality disorder (BPD) and second-wave (RR = 7.128; p = 0.012). Suicidality increased during the first-wave of Covid-19 pandemic in our sample. In the second-wave this was found in patients with SUD and BPD. These patients may be at particular risk of suicidality during the Covid-19 pandemic.

Liaison psychiatry before and after the COVID-19 pandemic

INTRODUCTION

the COVID-19 pandemic had an impact on hospital admissions. The clinical profiles of patients referred to liaison psychiatry teams (LPT) remained stable over the last few decades. We postulate changes in patient profiles due to the COVID-19 pandemic.

MATERIALS AND METHODS

a total of 384 patients admitted to a tertiary care University Hospital in Madrid (Spain) and referred to LPTs were recruited. Patients referred 5 months before and after the first admission for COVID-19 were included. Clinical and sociodemographic characteristics were collected, and non-parametric hypothesis contrast tests were used to study possible differences between both periods.

RESULTS

patients referred during the pandemic were significantly older (U = 2.006; p = .045), most of them were admitted to medical hospitalization units (χ2 (2) = 5.962; p = 015), and with a different reason for admission. There was an increase in the rate of adjustment disorders (χ2 (1) =7.893; p = 005) and delirium (χ2 (1) =9.413; p = 002), as well as psychiatric comorbidity (χ2 (2) = 9.930; p = .007), and a reduction in the proportion of patients treated for substance misuse (χ2 (5) = 19.152; p = .002). The number of deaths increased significantly (χ2 (1) = 6.611; p = .010). In persons over 65 years inappropriate prescription was significantly lower (χ2 (1) = 8.200; p = .004).

CONCLUSIONS

the pandemic had an impact on the activity of the LPTs due to the change in the clinical profile and evolution of referred patients, maintaining standards of care that are reflected through prescription.

Emerging Knowledge of the Neurobiology of COVID-19

Many patients with COVID-19 will experience acute or longer-term neuropsychiatric complications. The neurobiological mechanisms behind these are beginning to emerge; however, the neurotropic hypothesis is not strongly supported by clinical data. The inflammatory response to SARS-CoV-2 is likely to be responsible for delirium and other common acute neuropsychiatric manifestations. Vascular abnormalities such as endotheliopathies contribute to stroke and cerebral microbleeds, with their attendant neuropsychiatric sequelae. Longer-term neuropsychiatric syndromes fall into 2 broad categories: neuropsychiatric deficits occurring after severe (hospitalized) COVID-19 and "long COVID," which occurs in many patients with a milder acute COVID-19 illness.

Psychiatric liaison service referral patterns during the UK COVID-19 pandemic: An observational study

BACKGROUND AND OBJECTIVES

COVID-19 has had a profound effect on mental health. Liaison psychiatry teams assess and treat people in mental health crises in emergency departments (EDs) and on hospital wards. During the first pandemic wave, new Mental Health Crisis Assessment Services (MHCAS) were created to divert people away from EDs. Our objective was to describe patterns in referrals to psychiatric liaison services across the North Central London care sector (NCL) and explore the impact of a new MHCAS.

METHODS

Retrospective study using routinely collected data (ED and ward referrals) from five liaison psychiatry services across NCL (total population 1.5 million people). We described referrals (per week and month) by individual liaison services and cross-sector, and patterns of activity (January 1st 2020 -September 31st 2020, weeks 1-39) compared with the same period in 2019. We calculated changes in the proportion of ED attendees (all-cause) referred to liaison psychiatry.

RESULTS

From 2019-2020, total referrals decreased by 16.5% (12,265 to 10,247), a 16.4% decrease in ED referrals (9528 to 7965) and 16.6% decrease in ward referrals (2737 to 2282). There was a marked decrease in referrals during the first pandemic wave (March/April 2020), which increased after lockdown ended. The proportion of ED attendees referred to liaison psychiatry services increased compared to 2019.

CONCLUSIONS

People in mental health crisis continued to seek help via ED/MHCAS and a higher proportion of people attending ED were referred to liaison psychiatry services just after the first pandemic wave. MHCAS absorbed some sector ED activity during the pandemic.

Liaison Psychiatry During the Peak of the Coronavirus Pandemic: A Description of Referrals and Interventions

Introduction: The novel coronavirus SARS-CoV-2 belongs to the coronavirus family, a group of viruses that can cause upper respiratory infections in humans. Among other symptoms, it can present as an asymptomatic infection or as a more severe disease requiring hospitalization. Neuropsychiatric symptoms have been described in the acute phase of the illness and as long-term repercussions. We describe the characteristics and interventions in those COVID-19 patients referred to our liaison psychiatry service. Materials and Methods: This is a cross-sectional descriptive study. This study was carried out within the Department of Psychiatry of Cruces University Hospital (Basque Country, Spain). Data from each psychiatric consultation within our consultation-liaison service were consecutively obtained for 1 month from March 17 to April 17, 2020. We recruited data regarding clinical and referral characteristics and psychiatric interventions. Results: Of a total of 721 SARS-CoV-2 hospitalizations, 43 (5.6%) patients were referred to our psychiatry liaison service. The median age was 61 years old, and 62.8% were women. The infectious disease department was the most frequent petitioner (37.2%), and the most common reason for referral was patient anxiety (25.6%). A total of 67.4% of patients received psychological counseling and 55.8% received some pharmacological approach, with a median of 3.7 visits/calls per patient. In addition, 20.3% needed a medication switch due to potential interactions between psychotropics and drugs used to treat SARS-CoV-2. Discussion: In our study, up to 5.6% of SARS-CoV-2 hospitalized patients needed a psychiatric evaluation, especially for anxiety and mood symptoms. Psychosocial factors associated with the pandemic, drugs used to treat the infection, or a direct causative effect of the virus may explain our findings.

Psychiatric Admissions, Referrals, and Suicidal Behavior Before and During the COVID-19 Pandemic in Denmark: A Time-Trend Study

OBJECTIVE

To assess the patterns in psychiatric admissions, referrals, and suicidal behavior before and during the COVID-19 pandemic.

METHODS

This study utilized health records from hospitals and Emergency Medical Services (EMS) covering 46% of the Danish population (n = 2,693,924). In a time-trend study, we compared the number of psychiatric in-patients, referrals to mental health services and suicidal behavior in years prior to the COVID-19 pandemic to levels during the first lockdown (March 11 - May 17, 2020), inter-lockdown period (May 18 - December 15, 2020), and second lockdown (December 16, 2020 - February 28, 2021).

RESULTS

During the pandemic, the rate of psychiatric in-patients declined compared to pre-pandemic levels (RR = 0.95, 95% CI = 0.94 - 0.96, p < 0.01), with the largest decrease of 19% observed three weeks into the first lockdown. Referrals to mental health services were not significantly different (RR = 1.01, 95% CI = 0.92 - 1.10, p = 0.91) during the pandemic; neither was suicidal behavior among hospital contacts (RR = 1.04, 95% CI = 0.94 - 1.14, p = 0.48) nor EMS contacts (RR = 1.08, 95% CI = 1.00 - 1.18, p = 0.06). Similar trends were observed across nearly all age groups, sexes, and types of mental disorders examined. In the age group <18, an increase in the rate of psychiatric in-patients (RR = 1.11, 95% CI = 1.07 - 1.15, p < 0.01) was observed during the pandemic; however, this did not exceed the pre-pandemic, upwards trend in psychiatric hospitalizations in the age group <18 (p = 0.78).

CONCLUSION

The COVID-19 pandemic has been associated with a decrease in psychiatric hospitalizations, while no significant change was observed in referrals to mental health services and suicidal behavior. Psychiatric hospitalizations among children and adolescents increased during the pandemic; however, this appears to be a continuation of a pre-pandemic trend.

Trends of new-onset psychosis or mania in psychiatric emergency departments during the COVID19 pandemic: a longitudinal comparative study

COVID19 infection was associated with possible psychiatric manifestations, including psychosis and mania. In addition, psychiatric disorders might be triggered by severe psychological reactions to the pandemic or the measures taken to contain it. This study aimed to assess the trends of new-onset psychosis/mania during the pandemic timeline. Psychiatric emergency department records during January-July 2019 and 2020 of two regional mental health centers were manually examined. Cases of new-onset psychosis or mania were found in 326 out of 5161 records examined. The ratio of these cases increased by 45.5% in 2020 compared to 2019 (189 out of 2367, 137 out of 2479, respectively, p = 0.001). The peak increase was in April 2020 (9.4% vs. 4.7%, p = 0.015). There was no association between the rise of new-onset psychotic or manic episodes and national incidence of COVID19 cases, as observed during Israel 2nd wave. PCR tests were negative, except a single case. In this study, an increase in new-onset psychosis/mania was identified during the initial phase of the pandemic. Though causality could not be directly inferred, lack of infection symptoms, negative PCR testing and temporal distribution incongruent with COVID19 caseload did not support a direct effect of SARS-CoV-2. Alternative explanations are discussed, such as psychological reaction to stress and preventive measures, as well as case-shifting between different mental health settings.

Acute mental health presentations before and during the COVID-19 pandemic

BACKGROUND

A number of community based surveys have identified an increase in psychological symptoms and distress but there has been no examination of symptoms at the more severe end of the mental health spectrum.

AIMS

We aimed to analyse numbers and types of psychiatric presentations to inform planning for future demand on mental health services in light of the COVID-19 pandemic.

METHOD

We analysed electronic data between January and April 2020 for 2534 patients referred to acute psychiatric services, and tested for differences in patient demographics, symptom severity and use of the Mental Health Act 1983 (MHA), before and after lockdown. We used interrupted time-series analyses to compare trends in emergency department and psychiatric presentations until December 2020.

RESULTS

There were 22% fewer psychiatric presentations the first week and 48% fewer emergency department presentations in the first month after lockdown initiated. A higher proportion of patients were detained under the MHA (22.2 v. 16.1%) and Mental Capacity Act 2005 (2.2 v. 1.1%) (χ2(2) = 16.3, P < 0.0001), and they experienced a longer duration of symptoms before seeking help from mental health services (χ2(3) = 18.6, P < 0.0001). A higher proportion of patients presented with psychotic symptoms (23.3 v. 17.0%) or delirium (7.0 v. 3.6%), and fewer had self-harm behaviour (43.8 v. 52.0%, χ2(7) = 28.7, P < 0.0001). A higher proportion were admitted to psychiatric in-patient units (22.2 v. 18.3%) (χ2(6) = 42.8, P < 0.0001) after lockdown.

CONCLUSIONS

UK lockdown resulted in fewer psychiatric presentations, but those who presented were more likely to have severe symptoms, be detained under the MHA and be admitted to hospital. Psychiatric services should ensure provision of care for these patients as well as planning for those affected by future COVID-19 waves.
