Introduction: Despite rapid shifts in consultation-liaison psychiatry (CLP) training in residency, including increasing general residency training requirements from the Accreditation Council for Graduate Medical Education, greater utilization of advanced practice providers, and effects of the coronavirus-2019 pandemic, the Academy of Consultation-Liaison Psychiatry (ACLP) has not updated recommendations for residency training in CLP since 2014. A national survey of residency program directors in 2021 suggested many changes to the structure of CLP rotations at individual programs over the past decade.

Methods: We convened a workgroup of 8 ACLP members holding leadership positions in residency and fellowship education on local and national levels. The project was approved by the ACLP Executive Council and conducted via a three-stage iterative process.

Results: Consensus was reached on 34 recommendations across four domains, including structural issues, faculty supervsion, formal curriculum and evaluations, and elective experiences.

Discussion: Residents must spend sufficient time on CLP rotations to achieve relevant milestones. Given that consultants are expected to offer unique insight, the ideal placement of core CLP rotations comes at a time in residency where residents are able to provide expert opinion and lead teams. Faculty expertise in CLP and availability to provide direct supervision and oversight to trainees is essential. A separate and formal CLP didactic curriculum should exist, and elective opportunities should be offered to supplement training.

Conclusions: These recommendations are intended to guide residency program directors towards optimizing CLP training for all residents, including those who will eventually pursue CLP fellowship. Establishing a strong CLP foundation for all residents is essential for ensuring competency in providing psychiatric care for medically complex patients and collaborating with our colleagues in other specialties, as well as fostering trainee interest in pursuing a career in CLP.

Background: Major Depressive Disorder (MDD) is often associated with Subclinical Hypothyroidism (SCH), but the clinical and biochemical characteristics in young, first-episode, drug-naive patients remain unclear. This study aims to examine the prevalence and clinical correlates of SCH in this population to enhance screening and management strategies.

Method: A cross-sectional study included 917 young Chinese patients (aged 18-35) diagnosed with first-episode, drug-naive MDD. Comprehensive clinical assessments were conducted, involving demographic data, psychiatric evaluations using the Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), and Positive and Negative Syndrome Scale (PANSS), alongside biochemical measurements such as thyroid stimulating hormone, thyroid peroxidase antibodies (TPOAb), fasting blood glucose (FBG), total cholesterol (TC), high-density lipoprotein cholesterol (HDLC), low-density lipoprotein cholesterol (LDLC), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Binary logistic regression identified clinical correlates of SCH.

Results: The prevalence of SCH among the study population was 58%. Logistic regression analysis identified significant predictors of SCH, including higher HAMD scores (OR = 1.26), TPOAb (OR = 1.003), FBG (OR = 2.28), TC (OR = 1.66), SBP (OR = 1.11), and DBP (OR = 1.07). In contrast, lower HDLC levels (OR = 0.28) were inversely associated with SCH.

Conclusion: The high prevalence of SCH in young, first-episode, drug-naive MDD patients emphasizes the need for comprehensive metabolic and endocrine evaluations. Regular monitoring of thyroid function, glucose levels, blood pressure, and lipid profiles is crucial for early detection and intervention, potentially improving clinical outcomes in this vulnerable group.

Background: Delirium commonly occurs in older adults following surgery; although its pathophysiology is not fully understood, underlying neurodegeneration is a risk factor.

Objective: Examine the association of preoperative levels of markers of neuronal damage, neurofilament light (NfL) and phosphorylated tau (p-tau)₁₈₁, with postoperative delirium.

Methods: Preoperative CSF and plasma were obtained from 158 patients undergoing hip fracture repair and enrolled in the clinical trial "A STrategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients" (STRIDE). Delirium diagnosis was adjudicated by a consensus panel. The association of plasma and CSF NfL and p-tau₁₈₁ levels with delirium incidence and severity were examined for the overall cohort and for the subgroup (n=134) of patients without dementia.

Results: Patients who developed delirium were older, had lower Mini-Mental State Exam (MMSE) score, higher Clinical Dementia Rating (CDR) and Geriatric Depression Scale (GDS) scores at baseline; the overall incidence of delirium was 37.6% and 31.1% for the subgroup without dementia. Plasma and CSF p-tau₁₈₁ levels were not associated with delirium incidence or severity. CSF NfL levels were significantly associated with delirium severity, but not with incidence in the overall cohort. In the subgroup of patients without dementia, CSF NfL levels were significantly associated with increased odds of delirium incidence (OR 4.74, 95% CI 1.21-18.59, p=0.03) adjusted for age, sex, and CDR.

Conclusions: CSF NfL was significantly associated with delirium incidence and severity in patients without dementia undergoing hip fracture repair. Results confirm prior studies suggesting NfL as an important marker of delirium risk and supports an association between pre-existing axonal injury and delirium. These results highlight delirium vulnerability in older hip fracture patients, even when clinical dementia is not identified.

Background: Catatonia is a psychomotor syndrome associated with neurotransmitter disturbances, common in both psychiatric and medical settings. Hypoactivity of the GABA_A receptor is one of the predominant theories behind the pathophysiology of catatonia, affecting both motor functioning and emotional regulation. Benzodiazepines such as lorazepam are considered the first-line treatment for catatonia. However, up to 27% of catatonia cases fail to respond to benzodiazepines alone. Zolpidem, which can be used as a challenge, monotherapy, or augmentation agent, serves as a promising pharmacological agent for catatonia due to its unique pharmacodynamic and pharmacokinetic profile.

Objective: We sought to systematically examine the evidence behind zolpidem's use among adult patients to understand its clinical utility in the management of catatonia against prevailing treatments such as lorazepam and electroconvulsive therapy (ECT).

Methods: We conducted a systematic review using search terms related to zolpidem and catatonia in PubMed, EMBASE, and Web of Science. We followed PRISMA guidelines and identified 29 studies, including case studies and case series, that met inclusion criteria.

Results: We reviewed 35 cases in which zolpidem was used for catatonia management (age: M =51.5 ± 21.0 SD years; 68.6% female; Bush Francis Catatonia Rating Scale: M=22.2 ± 9.0 SD). Proportions of positive responses for zolpidem on catatonia varied by treatment approach: 91% as a challenge agent (n=10), 100% as a first-line monotherapy agent (n=3), 57% as a first-line combination therapy agent (n=4), 70% as a second-line monotherapy agent (n=7), and 100% as a second-line augmentation agent (n=4). In total, 28 out of the 35 reported cases of catatonia (80%) responded positively to zolpidem.

Conclusions: An 80% positive response rate for zolpidem in lysing catatonia is encouraging but may be an overestimate due to reporting bias of case level data. Results may be explained by zolpidem's selectivity for the α₁ subunit of the GABA_A receptor. Thus, zolpidem may be an under-utilized catatonia treatment and prove useful in situations when benzodiazepines fail or when ECT access is limited. Given that current literature on the use of zolpidem for catatonia is limited to case reports, more robust research in this area is warranted.

Background: Breastfeeding shares a complex, occasionally contradictory relationship with maternal mental health. Both positive and negative mood impacts have been noted in relation to breastfeeding initiation as well as cessation. Though popular magazines and online forums discuss the onset of psychiatric symptoms following weaning, there is limited medical literature detailing this relationship.

Objective: To increase awareness regarding psychiatric symptom development in the context of breastfeeding cessation.

Methods: We describe the case of a patient who developed psychiatric symptoms shortly after weaning, including acute-onset insomnia and worsening anxiety. A literature review of psychiatric symptom development following breastfeeding cessation was conducted using the search engines PubMed, PsycINFO (EBSCOhost), and Embase. Search terms included controlled vocabulary, keywords (within title and abstract fields), synonyms, and related concepts for postpartum period, postpartum depression, postpartum anxiety, breastfeeding cessation, breastfeeding weaning, lactation, dysphoric milk ejection reflex, and insomnia. Relevant case reports were reviewed and compared to this case. Information including the patient's age, psychiatric symptoms, past psychiatric history, medical workup, treatment, and outcome was extracted from each article.

Results: Nine patients who developed psychiatric symptoms following breastfeeding cessation were identified in six case reports. Three patients experienced recurrent symptoms in multiple pregnancies. This led to documentation of 13 discrete postweaning syndromes. All cases involved either first-time parents, those new to breastfeeding, or those experiencing symptoms during multiple weaning periods. Synthesizes data from the article review. As with our case, 11 clinical cases describe sleep changes (primarily insomnia) and 4 discuss anxiety symptoms. Treatment varied based upon symptoms experienced, with no consistently effective treatments identified across cases.

Conclusions: This case of unspecified insomnia and anxiety disorders following abrupt weaning adds to the limited literature in the field and suggests that physiologic and psychologic factors associated with breastfeeding cessation may play a role in the development or worsening of postpartum mood disorders. Intensive psychiatric treatment resulted in resolution of the patient's symptoms. The relationship between weaning and psychiatric disorders is evident in the lay press but is underrepresented in medical literature. Additional research is needed to better understand this relationship so that physicians can counsel, diagnose, and treat patients more effectively.

Background: Nonprescribed substance use (NPSU) is a recognized phenomenon exhibited by patients with substance use disorders while admitted to inpatient hospitals. What factors distinguish patients who engage in NPSU, or how their hospitalizations and outcomes differ, remains to be understood in full.

Objectives: Our study describes a cohort of medically admitted patients with substance use disorders with behaviors concerning for NPSU during their hospitalization.

Methods: We extracted electronic health record data for all hospital encounters when an addiction consult was documented (n = 3100). We defined NPSU cases during a clinical, interdisciplinary case review in which patients were deemed high risk based on team members' observations of one or more behaviors described in the NPSU Checklist. These individuals were placed on a "NPSU Protocol," which was implemented for optimization of care, destigmatization, and risk mitigation (n = 61). We compared clinical characteristics, resource utilization, and treatment outcomes among the NPSU cohort to addiction consult patients without suspicion of NPSU but with stimulant or opioid use disorder diagnoses.

Results: Patients on the NPSU protocol were younger and had higher rates of infectious disease diagnoses reported during hospitalization than patients without concern for NPSU. Hospitalizations for individuals suspected of NPSU were longer, had higher rates of before medically advised discharge, as well as discharges without medications for opioid use disorder. These outcome differences were also observed when analysis was restricted to hospitalizations in which an infectious disease was diagnosed.

Conclusions: Our study characterizes a population of people who exhibited behaviors concerning for NPSU and highlights key outcome disparities. To our knowledge, this study is the first to show a direct correlation between infectious disease diagnosis and NPSU, as well as a direct correlation between suspected NPSU and outcomes such as before medically advised discharge and discharge without medications for opioid use disorder, irrespective of infectious disease diagnosis. Further study is necessary to determine interventions to reduce poor outcomes among hospitalized patients with NPSU.

Background: In 2021, suicide was the second leading cause of death in early adolescent Americans ages 10-14. Research into suicidal behavior in this age group is limited. We report on prior psychiatric care, attempt method, and attempt outcomes in a cohort of 164 early adolescents accrued by first suicide attempt coming to medical attention.

Methods: Our cohort constitutes a subsample from a previously reported retrospective-prospective study identified through the Rochester Epidemiology Project that recruited individuals making first suicide attempts coming to medical attention (index attempt [IA]) during a 22-year period (1/1/1986-31/12/07). Among 1490 all-age index attempters followed until 12/31/2010, 164 (11.0%) were aged 10-14.

Results: 3/164 died on IA (1.8% of the cohort; two females, one male). Nearly half (72/164, 43.9%) had no prior psychiatric history. Females were less likely than males to have seen a mental health provider (P = 0.029) or been prescribed psychiatric medications (P < 0.001) prior to IA. Medication overdose was the most common attempt method in females (81/128, 63.3%), while cutting or piercing wounds were the most common method in males (13/36, 36.1%). Females were significantly more likely than males to overdose (P = 0.001). Of IA survivors, 19.9% (32/161) were initially medically hospitalized, 52.8% (85/161) were psychiatrically hospitalized-initially or in transfer-and 37.2% (60/161) were discharged without hospitalization.

Conclusion: Medication overdoses accounted for over half of all IAs and were significantly more common in females. While IA mortality was low relative to older patients from the all-age-cohort, morbidity was substantial with nearly a fifth of attempts severe enough to warrant medical hospitalization and more than half initial or eventual psychiatric hospitalization. These findings emphasize the importance of both means restriction and identification of early adolescents at risk before they make their first attempt.

Medical psychiatry units (MPUs), also known as complexity intervention units, represent an important innovation for integrating medical and behavioral health care in the hospital setting, thereby reducing the need for sequential medical and psychiatric hospitalization. As US hospitals face an increased demand for mental health services, interest in the MPU model is gaining momentum. However, there is no shared definition for what constitutes an MPU, and significant variation exists among units across the United States that have been designated as an MPU. The lack of a unified definition for MPUs results in significant variability and poses challenges for creating new MPUs and studying existing MPUs. To address this gap, the Medical-Psychiatry Unit Consortium recruited a panel of MPU experts to conduct a consensus study. The consortium used a survey to assess the relative importance of various characteristics of MPUs within the following categories: structural organization, environment and design, spectrum of care, staffing, and culture of care. After two rounds of a modified Delphi process, consensus was achieved with regard to which characteristics are necessary or preferred vs. not necessary or harmful. The necessary or preferred characteristics include those that would be expected on a general medical unit, such as having cardiac telemetry monitoring capabilities, as well as characteristics typical of a psychiatric unit, such as locked unit doors, locked cabinets for patient belongings, and common area or milieu. Overall, this suggests that an ideal MPU combines the ability to provide acute medical care with acute psychiatric care. Notably, staffing and culture of care emerged as categories with the highest ranking of necessary characteristics, outweighing environment, design, or the breadth of services offered. These findings suggest that MPU experts feel teamwork and having a shared mission are critical components of effective MPUs and highlight the importance of staff recruitment and training.
