Changes in waiting time, need for mechanical circulatory support and outcomes in paediatric heart transplant recipients.

AIMS: Heart transplantation is a well-established treatment for end-stage heart failure in paediatric patients, demonstrating excellent long-term outcomes. METHODS: This retrospective study analyses 35 years of data on 244 paediatric recipients (<18 years) at a single institution from 1986 to 2022. The analysis explores changes in diagnoses, survival, waiting times and mechanical circulatory support (MCS) over three decades (1991-2000, 2001-2010 and 2011-2020). RESULTS: Survival outcomes significantly improved over the study period, with 1-year survival rates increasing from 79.3% (1991-2000) to 92.3% (2011-2020, P = 0.041). The median overall survival was 18.0 years, and median conditional survival to 1 year post-transplant was 20.9 years. Survival differences were noted among age groups, with infants under 1 year of age experiencing higher early mortality, and adolescents (aged 11-17 years) facing increased long-term risks, possibly linked to adult donor characteristics. Waiting times for heart transplantation increased, especially for younger age groups (0-5 and 6-10 years), reflecting the growing demand for donor organs. The use of MCS, including ventricular assist devices (VAD), surged, with 67% of recipients in the most recent decade receiving pre-transplant VAD support. Importantly, despite prolonged waiting times and increased VAD use, overall survival continued to be favourable. CONCLUSIONS: Early and long-term results after paediatric heart transplantation have been continuously improving over the past decades. Despite an increased demand for donor organs and the growing reliance on VAD as bridge to transplantation, post-transplantation survival is not compromised.

Multilevel perspectives on the implementation of the collaborative care model for depression and anxiety in primary care.

BACKGROUND: The Collaborative Care Model (CoCM) is an evidence-based mental health treatment in primary care. A greater understanding of the determinants of successful CoCM implementation, particularly the characteristics of multi-level implementers, is needed. METHODS: This study was a process evaluation of the Collaborative Behavioral Health Program (CBHP) study (NCT04321876) in which CoCM was implemented in 11 primary care practices. CBHP implementation included screening for depression and anxiety, referral to CBHP, and treatment with behavioral care managers (BCMs). Interviews were conducted 4- and 15-months post-implementation with BCMs, practice managers, and practice champions (primary care clinicians). We used framework-guided rapid qualitative analysis with the Consolidated Framework for Implementation Research, Version 2.0, focused on the Individuals domain, to analyze response data. These data represented the roles of Mid-Level Leaders (practice managers), Implementation Team Members (clinicians, support staff), Innovation Deliverers (BCMs), and Innovation Recipients (primary care/CBHP patients) and their characteristics (i.e., Need, Capability, Opportunity, Motivation). RESULTS: Mid-level leaders (practice managers) were enthusiastic about CBHP (Motivation), appreciated integrating mental health services into primary care (Need), and had time to assist clinicians (Opportunity). Although CBHP lessened the burden for implementation team members (clinicians, staff; Need), some were hesitant to reallocate patient care (Motivation). Innovation deliverers (BCMs) were eager to deliver CBHP (Motivation) and confident in assisting patients (Capability); their opportunity to deliver CBHP could be limited by clinician referrals (Opportunity). Although CBHP alleviated barriers for innovation recipients (patients; Need), it was difficult to secure services for those with severe conditions (Capability) and certain insurance types (Opportunity). CONCLUSIONS: Overall, respondents favored sustaining CoCM and highlighted the positive impacts on the practice, health care team, and patients. Participants emphasized the benefits of integrating mental health services into primary care and how CBHP lessened the burden on clinicians while providing patients with comprehensive care. Barriers to CBHP implementation included ensuring appropriate patient referrals, providing treatment for patients with higher-level needs, and incentivizing clinician engagement. Future CoCM implementation should include strategies focused on education and training, encouraging clinician buy-in, and preparing referral paths for patients with more severe conditions or diverse needs.

Addressing Issue of Fast-Tracking in Consultation-Liaison Psychiatry Fellowship Training: Expanding Access or Undermining Competence?

Fast-tracking is an option for residents to pursue fellowship training in place of their final residency year. It is currently permissible to fast-track into a child and adolescent psychiatry fellowship, but this remains a controversial idea for other psychiatry subspecialties. In 2022, the Annual Meeting of the Academy of Consultation-Liaison Psychiatry featured a plenary session debate about the pros and cons of fast-tracking. Here, the authors present some of the information discussed at that session and highlight the potential benefits and pitfalls of fast-tracking into consultation-liaison psychiatry.

The Delphi Delirium Management Algorithms. A practical tool for clinicians, the result of a modified Delphi expert consensus approach.

Delirium is common in hospitalised patients, and there is currently no specific treatment. Identifying and treating underlying somatic causes of delirium is the first priority once delirium is diagnosed. Several international guidelines provide clinicians with an evidence-based approach to screening, diagnosis and symptomatic treatment. However, current guidelines do not offer a structured approach to identification of underlying causes. A panel of 37 internationally recognised delirium experts from diverse medical backgrounds worked together in a modified Delphi approach via an online platform. Consensus was reached after five voting rounds. The final product of this project is a set of three delirium management algorithms (the Delirium Delphi Algorithms), one for ward patients, one for patients after cardiac surgery and one for patients in the intensive care unit.

Scattered tree death contributes to substantial forest loss in California.

In recent years, large-scale tree mortality events linked to global change have occurred around the world. Current forest monitoring methods are crucial for identifying mortality hotspots, but systematic assessments of isolated or scattered dead trees over large areas are needed to reduce uncertainty on the actual extent of tree mortality. Here, we mapped individual dead trees in California using sub-meter resolution aerial photographs from 2020 and deep learning-based dead tree detection. We identified 91.4 million dead trees over 27.8 million hectares of vegetated areas (16.7-24.7% underestimation bias when compared to field data). Among these, a total of 19.5 million dead trees appeared isolated, and 60% of all dead trees occurred in small groups ( ≤ 3 dead trees within a 30 × 30 m grid), which is largely undetected by other state-level monitoring methods. The widespread mortality of individual trees impacts the carbon budget and sequestration capacity of California forests and can be considered a threat to forest health and a fuel source for future wildfires.

DRESS syndrome: quetiapine associated case report and literature review.

Drug rash with eosinophilia and systemic symptoms (DRESS syndrome) is a rare systemic adverse drug reaction with a high mortality rate. Cases of DRESS syndrome have been reported with almost all classes of psychiatric medications, but data remains limited. We describe the case of a 33-year-old woman who presented with acute respiratory distress syndrome secondary to severe pulmonary blastomycosis. Her hospital course was complicated by severe agitation for which the psychiatry consult team was involved and several medications were trialed including quetiapine. She developed a diffuse erythematous rash during her hospital stay and later eosinophilia and transaminitis consistent with DRESS syndrome due to either quetiapine or lansoprazole based on the timeline. Both medications were discontinued, and she was started on a prednisone taper leading to resolution of the rash, eosinophilia, and transaminitis. Her HHV-6 IgG titer later returned elevated at 1:1280. DRESS syndrome along with many other cutaneous drug reactions can be associated with psychiatric medications and familiarity and recognition are imperative. There are limited reports of quetiapine-associated DRESS syndrome in the literature; however, rash and eosinophilia should alert psychiatrists to the potential for quetiapine to be a precipitant for DRESS syndrome.

Implementation Barriers and Experiences of Eligible Patients Who Failed to Enroll in Collaborative Care for Depression and Anxiety.

BACKGROUND: Effective and efficient implementation of the Collaborative Care Model (CoCM) for depression and anxiety is imperative for program success. Studies examining barriers to implementation often omit patient perspectives. OBJECTIVES: To explore experiences and attitudes of eligible patients referred to CoCM who declined participation or were unable to be reached, and identify implementation barriers to inform strategies. DESIGN: Convergent mixed-methods study with a survey and interview. PARTICIPANTS: Primary care patients at an academic medical center who were referred to a CoCM program for anxiety and depression by their primary care clinician (PCC) but declined participation or were unable to be reached by the behavioral health care manager to initiate care (n = 80). Interviews were conducted with 45 survey respondents. MAIN MEASURES: Survey of patients' referral experiences and behavioral health preferences as they related to failing to enroll in the program. Interview questions were developed using the Consolidated Framework for Implementation Research version 2.0 (CFIR 2.0) to identify implementation barriers to enrollment. KEY RESULTS: Survey results found that patients were uncertain about insurance coverage, did not understand the program, and felt services were not necessary. Referred patients who declined participation were concerned about how their mental health information would be used and preferred treatment without medication. Men agreed more that they did not need services. Qualitative results exhibited a variety of implementation determinants (n = 23) across the five CFIR 2.0 domains. Barriers included mental health stigma, perceiving behavioral health as outside of primary care practice guidelines, short or infrequent primary care appointments, prioritizing physical health over mental health, receiving inaccurate program information, low motivation to engage, and a less established relationship with their PCC. CONCLUSIONS: Multiple barriers to enrollment led to failing to link patients to care, which can inform implementation strategies to address the patient-reported experiences and concerns.

An Interdisciplinary Reappraisal of Delirium and Proposed Subtypes.

An interdisciplinary plenary session entitled "Rethinking and Rehashing Delirium" was held during the 2021 Annual Meeting of the Academy of Consultation-Liaison Psychiatry to facilitate dialog on the prevalent approach to delirium. Panel members included a psychiatrist, neurointensivist, and critical care specialist, and attendee comments were solicited with the goal of developing a statement. Discussion was focused on a reappraisal of delirium and, in particular, its disparate terminology and history in relation to acute encephalopathy. The authors endorse a recent joint position statement that describes acute encephalopathy as a rapidly evolving (<4 weeks) pathobiological brain process that presents as subsyndromal delirium, delirium, or coma and suggest the following points of refinement: (1) to suggest that "delirium disorder" describe the diagnostic construct including its syndrome, precipitant(s), and unique pathophysiology; (2) to restrict the term "delirium" to describing the clinical syndrome encountered at the bedside; (3) to clarify that the disfavored term "altered mental status" may occasionally be an appropriate preliminary designation where the diagnosis cannot yet be specified further; and (4) to provide rationale for rejecting the terms acute brain injury, failure, or dysfunction. The final common pathway of delirium appears to involve higher-level brain network dysfunction, but there are many insults that can disrupt functional connectivity. We propose that future delirium classification systems should seek to characterize the unique pathophysiological disturbances ("endotypes") that underlie delirium and delirium's individual neuropsychiatric symptoms. We provide provisional means of classification in hopes that novel subtypes might lead to specific intervention to improve patient experience and outcomes. This paper concludes by considering future directions for the field. Key areas of opportunity include interdisciplinary initiatives to harmonize efforts across specialties and settings, enhance underrepresented groups in research, integration of delirium and encephalopathy in coding, development of relevant quality and safety measures, and exploration of opportunities for translational science.

Identity and Relationship-Based Discrimination, and Mental Health in a Sample of Sexual Minority Male Couples.

PURPOSE: The study explored the unique associations of individual identity-based discrimination and relationship-based discrimination with mental health among sexual minority male couples. It also examined whether couples' relationship functioning moderated associations between relationship-based discrimination, the experience of one's romantic relationship being devalued, and mental health outcomes. METHODS: Baseline dyadic data drawn from a clinical trial involving 70 couples (N= 140) were analyzed using Actor-Partner Interdependence Modeling. The sample consisted of sexual minority men, of which 54.3% identified as a person of color. Each partner completed the computerized survey independently. Data were collected using the Relationship Marginalization Scale, Dyadic Adjustment Scale, Generalized Anxiety Disorder-7, and Center for Epidemiologic Studies Depression Scale-Revised scales. RESULTS: Dyadic adjustment moderated (i.e., buffered against) the association between relationship-based discrimination and depressive symptoms. The effects appeared to follow an intra-individual pattern (B ACTOR = -0.06, p = .048 and B PARTNER = -0.07, p = .030) indicating the lack of evidence for crossover effects. The interaction terms predicting anxiety yielded non-significant results. CONCLUSIONS: The current research suggests that dyadic functioning buffers against the effects of stigma. These findings point to the potential utility of interventions to improve relationship functioning into interventions addressing stigma among partnered sexual minority men.

Species densities, assembly order, and competence jointly determine the diversity-disease relationship.

Since species vary in abundance and host competence (i.e., ability to get infected and transmit a pathogen), changes in species composition caused by biodiversity loss impacts disease dynamics. Forecasting effects of species composition on disease depends on community (dis)assembly, processes determining how species are added to (or lost from) communities. We simulated community assembly by planting mesocosms, nested along a richness gradient, and tested how relationships between richness, species assembly order, and overall density affect disease risk. Mesocosms with up to six crop species of varying competence were inoculated with a soilborne fungal pathogen, Rhizoctonia solani. Disease was measured as species-level prevalence, community-level prevalence, and total number of diseased plants. Regardless of metric, richness limited disease when species assembly order negatively correlated with competence and total density remained unchanged with richness. When density increased with richness or species assembled randomly, richness primarily correlated positively or weakly with disease. Our results align with theoretical expectations and represent the first empirical study to test the influence of species densities, assembly order, and competence on diversity-disease relationships.

Hospital Guardianship: A Quality Needs Assessment of "Unbefriended" Patients Who Lack Decisional Capacity.

BACKGROUND: The "unbefriended" patient does not demonstrate capacity to make their own medical decisions, does not have an advance directive, and lacks a surrogate decision maker. For these patients without a designated health care proxy, hospitals may need to petition for public guardianship, a notoriously arduous process with undefined impact on hospital resources. OBJECTIVE: The objective of this study was to describe the characteristics, system needs, and financial impact of unrepresented inpatients in an academic, tertiary care, urban medical center. METHODS: The Northwestern Memorial Hospital Quality and Patient Safety Committee approved a systematic needs assessment. Retrospective chart review was conducted for patients admitted from September 1, 2013 to August 31, 2019 for whom the hospital petitioned for a public guardian. RESULTS: From fiscal years 2014 to 2019, 156 patients were petitioned for public guardianship. The number of cases rose sequentially from 8 in 2014 to 44 in 2019. The 2 most common conditions that impaired capacity were neurocognitive disorders (56.4%) and psychotic disorders (17.9%). The psychiatry consultation service consulted 71.2% of cases vs 71.1%. There were 2347 medically unnecessary hospital days related to the pursuit of guardianship, and the associated costs to the health system were estimated to be more than $5.8 million. CONCLUSIONS: The number of unbefriended patients who lacked decisional capacity necessitating public guardianship dramatically escalated over 5 years. These patients had high rates of homelessness and psychiatric illness, consistent with previous research. Further investigation is needed to understand and address the needs of this vulnerable population.

Community-level prevalence of a forest pathogen, not individual-level disease risk, declines with tree diversity.

Understanding why diversity sometimes limits disease is essential for managing outbreaks; however, mechanisms underlying this 'dilution effect' remain poorly understood. Negative diversity-disease relationships have previously been detected in plant communities impacted by an emerging forest disease, sudden oak death. We used this focal system to empirically evaluate whether these relationships were driven by dilution mechanisms that reduce transmission risk for individuals or from the fact that disease was averaged across the host community. We integrated laboratory competence measurements with plant community and symptom data from a large forest monitoring network. Richness increased disease risk for bay laurel trees, dismissing possible dilution mechanisms. Nonetheless, richness was negatively associated with community-level disease prevalence because the disease was aggregated among hosts that vary in disease susceptibility. Aggregating observations (which is surprisingly common in other dilution effect studies) can lead to misinterpretations of dilution mechanisms and bias towards a negative diversity-disease relationship.

Long-term experience using CNI-free immunosuppression in selected paediatric heart transplant recipients.

BACKGROUND: CNI-free immunosuppression with conversion to mTORi-based immunosuppression has been demonstrated to reduce CNI-toxicity and to exhibit anti-proliferative properties. However, the experience of CNI-free immunosuppression in paediatric heart transplantation is limited. METHODS: A retrospective analysis was conducted of 129 paediatric heart transplants performed between 1997 and 2015. Fifteen patients with clinically indicated conversion from CNI-based to CNI-free immunosuppression were identified. Survival data, rejection episodes, renal function, post-transplantation lymphoproliferative disorder and CAV, including examination with OCT were analysed. RESULTS: Immunosuppression conversion was successful in all patients. Fourteen of 15 patients (93%) are currently living with good graft function. Median post-transplant survival was 15 years (range, 5-23 years), and median follow-up since conversion was 6 years (range, 1-11 years). Mild (grade 1R) ACR was present in three patients after discontinuation of CNIs. The recovery of renal function with a significant increase in eGFR was observed at 1 and 3 years after conversion. No patient had angiographic signs of macroscopic CAV according to the current ISHLT classification; however, OCT showed the signs of angiographically silent CAV in all patients. CAV did not progress in any patient, implying CAV was stabilised by mTORi-based CNI-free immunosuppression. CONCLUSIONS: CNI-free immunosuppression based on mTORis is a safe and appropriate strategy for maintenance therapy in selected paediatric patients, significantly improves renal function and stabilises CAV. OCT revealed early development of angiographically silent CAV.

Collaborative care for depression management in primary care: A randomized roll-out trial using a type 2 hybrid effectiveness-implementation design.

BACKGROUND: The Collaborative Care Model (CoCM) is a well-established treatment for depression in primary care settings. The critical drivers and specific strategies for improving implementation and sustainment are largely unknown. Rigorous pragmatic research is needed to understand CoCM implementation processes and outcomes. METHODS: This study is a hybrid Type 2 randomized roll-out effectiveness-implementation trial of CoCM in 11 primary care practices affiliated with an academic medical center. The Collaborative Behavioral Health Program (CBHP) was developed as a means of improving access to effective mental health services for depression. Implementation strategies are provided to all practices. Using a sequential mixed methods approach, we will assess key stakeholders' perspectives on barriers and facilitators of implementation and sustainability of CBHP. The speed and quantity of implementation activities completed over a 30-month period for each practice will be assessed. Economic analyses will be conducted to determine the budget impact and cost offset of CBHP in the healthcare system. We hypothesize that CBHP will be effective in reducing depressive symptoms and spillover effects on chronic health conditions. We will also examine differential outcomes among racial/ethnic minority patients. DISCUSSION: This study will elucidate critical drivers of successful CoCM implementation. It will be among the first to conduct economic analyses on a fee-for-service model utilizing billing codes for CoCM. Data may inform ways to improve implementation efficiency with an optimization approach to successive practices due to the roll-out design. Changes to the protocol and current status of the study are discussed.

Internalizing symptoms, intersectional discrimination, and social support among Asian-Pacific Islander sexual and gender minority adults.

OBJECTIVE: This study examined associations of discrimination, social support, and their interaction, with internalizing symptoms among Asian-Pacific Islander (API) sexual and gender minority (SGM) adults in the U.S. METHOD: Analyses included data from 544 participants who completed an online survey, including measures of three internalizing symptoms (anxiety, depression, and somatization), five forms of discrimination (racism, heterosexism/cisgenderism, and three forms of intersectional discrimination), and two types of social support (acceptance for sexual/gender identity, general social support). RESULTS: All forms of discrimination were positively associated with all internalizing symptoms, with the strongest associations with somatization symptoms; further, acceptance for sexual/gender identity was negatively associated with all internalizing symptoms. Overall social support did not buffer associations of discrimination with internalizing symptoms. Positive associations between discrimination and symptoms were generally stronger at higher social support levels, and social support had weaker negative associations with internalizing symptoms at higher discrimination levels. CONCLUSION: Findings suggest the importance of increasing sexual/gender identity-specific social support, attending to somatization symptoms as an important manifestation of discrimination and reducing societal discrimination to address mental health needs of API SGM adults in the U.S. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Improving Payment for Collaborative Mental Health Care in Primary Care.

BACKGROUND: There is strong evidence supporting implementation of the Collaborative Care Model within primary care. Fee-for-service payment codes, published by Current Procedural Terminology in 2018, have made collaborative care separately reimbursable for the first time. These codes (ie, 99492-99494) reimburse for time spent per month by any member of the care team engaged in Collaborative Care, including behavioral care managers, primary care providers, and consulting psychiatrists. Time-based billing for these codes presents challenges for providers delivering Collaborative Care services. OBJECTIVES: Based on experience from multiple health care organizations, we reflect on these challenges and provide suggestions for implementation and future refinement of the codes. CONCLUSIONS: Further refinements to the codes are encouraged, including moving from a calendar month to a 30-day reimbursement cycle. In addition, we recommend payers adopt the new code proposed by the Centers for Medicare and Medicaid Services to account for smaller increments of time.

Education of Children With Cyanotic Congenital Heart Disease After Neonatal Cardiac Surgery.

BACKGROUND: The aim of the study was to evaluate the educational achievement of patients diagnosed with univentricular heart physiology (UVHP) or transposition of the great arteries (TGA) after neonatal cardiac surgery. METHODS: An exploratory online survey was performed with patients registered with the National Register for Congenital Heart Defects in Germany. For this publication, a subgroup analysis was conducted among patients diagnosed with TGA (n = 173; 36.3%) and UVHP (n = 304; 63.7%). RESULTS: Median age of the sample at school enrollment was 6 years (range, 5-8 years). The majority were enrolled at a standard elementary school (n = 368 of 477; 77.1%), although patients with UVHP were enrolled significantly more often at a special needs school (n = 52 of 304; 17.1%, TGA patients n = 11/ of 173; 6.4%, P < .001). A total of 45.8% (n = 66 of 144) of the patients graduated with a high school diploma. A substantial number of patients had been diagnosed with behavioral or learning disorders (TGA patients n = 63 of 173 [36.4%], UVHP patients n = 148 of 304 [48.7%]) and received early supportive therapy or remedial teaching before (TGA patients n = 89 of 173 [51.4%], UVHP patients n = 209 of 304 [68.8%]) and/or during their school careers (TGA patients n = 54 of 173 [31.2%], UVHP patients n = 120 of 304 [39.5%]). CONCLUSIONS: A large proportion of patients who underwent neonatal cardiac surgery graduated with a high school diploma. These results are of great importance to congenital heart defect patients, affected families, and treating physicians. Nevertheless, study participants, especially patients with UVHP, face some academic challenges. We conclude that long-term follow-up examinations and regular developmental assessments may be beneficial.

Sporulation Potential of Phytophthora ramorum Differs Among Common California Plant Species in the Big Sur Region.

Sudden oak death (SOD), caused by the generalist pathogen Phytophthora ramorum, has profoundly impacted California coastal ecosystems. SOD has largely been treated as a two-host system, with Umbellularia californica as the most transmissive host, Notholithocarpus densiflorus less so, and remaining species as epidemiologically unimportant. However, this understanding of transmission potential primarily stems from observational field studies rather than direct measurements on the diverse assemblage of plant species. Here, we formally quantify the sporulation potential of common plant species inhabiting SOD-endemic ecosystems on the California coast in the Big Sur region. This study allows us to better understand the pathogen's basic biology, trajectory of SOD in a changing environment, and how the entire host community contributes to disease risk. Leaves were inoculated in a controlled laboratory environment and assessed for production of sporangia and chlamydospores, the infectious and resistant propagules, respectively. P. ramorum was capable of infecting every species in our study and almost all species produced spores to some extent. Sporangia production was greatest in N. densiflorus and U. californica and the difference was insignificant. Even though other species produced much less, quantities were nonzero. Thus, additional species may play a previously unrecognized role in local transmission. Chlamydospore production was highest in Acer macrophyllum and Ceanothus oliganthus, raising questions about the role they play in pathogen persistence. Lesion size did not consistently correlate with the production of either sporangia or chlamydospores. Overall, we achieved an empirical foundation to better understand how community composition affects transmission of P. ramorum.

Psychiatric Aspects of Chloroquine and Hydroxychloroquine Treatment in the Wake of Coronavirus Disease-2019: Psychopharmacological Interactions and Neuropsychiatric Sequelae.

BACKGROUND: Chloroquine and hydroxychloroquine are among several experimental treatments being investigated in the urgent response to the coronavirus disease-2019. With increased use of these medications, physicians need to become knowledgeable of these drugs' neuropsychiatric side effects and interactions with psychiatric medications. OBJECTIVE: Clarify evidence base regarding the psychiatric side effects and psychiatric drug interactions of chloroquine and hydroxychloroquine. METHODS: A literature review was performed in PubMed from 1950 to 2020 regarding psychiatric topics and targeted pharmacological properties of chloroquine and hydroxychloroquine. RESULTS: First, chloroquine and hydroxychloroquine may mildly inhibit CYP2D6 metabolism of psychiatric medications, and psychiatric medications that interfere with CYP2D6 or CYP3A4 activity could alter chloroquine and hydroxychloroquine levels. Second, they may prolong the QT interval, warranting caution with concomitant prescription of other QT prolonging agents. Finally, neuropsychiatric side effects are very uncommon but possible and include a potentially prolonged phenomenon of "psychosis after chloroquine." Hydroxychloroquine has less information available about its neuropsychiatric side effects than chloroquine, with psychosis literature limited to several case reports. Weak evidence suggests a possible association of hydroxychloroquine exposure and increased suicidal ideation. It is not clear whether patients with psychiatric illness are more vulnerable to neuropsychiatric sequela of these medications; however, overdose of these medications by suicidal patients has high risk of mortality. CONCLUSION: The risk of neuropsychiatric side effects of chloroquine and hydroxychloroquine when used for coronavirus disease-2019 treatment is not known. Best practice may include suicide risk assessment for patients treated with hydroxychloroquine. However, delirium is expected to be a more likely etiology of neuropsychiatric symptoms in critically ill patients treated for coronavirus disease-2019, and adjustment disorder is a much more likely etiology of anxiety and depression symptoms than the side effects of chloroquine or hydroxychloroquine.
