Proactive Consultation-Liaison Psychiatry: American Psychiatric Association Resource Document.

In 2019, the American Psychiatric Association Council on Consultation-Liaison (C-L) Psychiatry convened a work group to develop a resource document on proactive C-L psychiatry. A draft of this document was reviewed by the Council in July 2020, and a revised version was approved by this Council in September 2020. The accepted version was subsequently reviewed by the American Psychiatric Association Council on Health Care Systems and Financing in November 2020. The final version was approved by the Joint Reference Committee on November 24, 2020, and received approval for publication by the Board of Trustees on December 12, 2020. This resource document describes the historical context and modern trends that have given rise to the model of proactive C-L psychiatry. Styled as an inpatient corollary to outpatient collaborative care models, proactive C-L provides a framework of mental health care delivery in the general hospital designed to enhance mental health services to a broad range of patients. Its 4 elements include systematic screening for active mental health concerns, proactive interventions tailored to individual patients, team-based care delivery, and care integration with primary teams and services. Studies have found that proactive C-L psychiatry is associated with reduced hospital length of stay, enhanced psychiatric service utilization, reduced time to psychiatric consultation, and improved provider and nurse satisfaction. These favorable results encourage further studies that replicate and build upon these findings. Additional outcomes such as patient experience, health outcomes, and readmission rates deserve investigation. Further studies are also needed to examine a broader array of team compositions and the potential value of proactive C-L psychiatry to different hospital settings such as community hospitals, surgery, and critical care.

Attitude change after a curriculum on the science and philosophy of well-being and happiness for high school students: A classroom-randomized trial.

BACKGROUND: Multiple interventions have been tested to promote well-being in high school students, often focusing on depression prevention. AIMS: To test the impact of a one-semester active learning curriculum covering the modern science and philosophy of well-being and happiness on attitudinal measures related to the curriculum and standard measures of depression and well-being. SAMPLE: Subjects were first-year students in an urban high school in Beijing, China (equivalent to US tenth grade). METHODS: Nine classrooms were randomly assigned to the intervention curriculum (n = 252), and nine classrooms were randomly assigned to a traditional psychology curriculum (n = 263). Students completed questionnaires pre- and post-semester including a Positive Attitude Scale (PAS, concerning Relatedness, Competence, Autonomy, Gratitude, Calmness, Mindfulness, and Hope), Positive and Negative Affect Scale (PANAS), Centers for Epidemiological Studies Depression Scale (CES-D), Life Satisfaction Scale (LS), Subjective Happiness Scale (SHS), Meaning in Life Questionnaire (MLQ), and a test of knowledge about well-being (Knowledge Test, KT). RESULTS: In a hierarchical linear model, there were statistically significant intervention effects on six of the seven subscales of the PAS, on PANAS balance, and on the KT. CES-D, LS, SHS, and MLQ were improved but not significantly so. Notable overall secular trends in measures of well-being were observed, with a peak in September and nadir in April. CONCLUSIONS: A one-semester course for high school students regarding well-being and happiness demonstrated significant changes in positive attitudes, affective balance, and knowledge about happiness. Circannual trends in well-being measures over the academic year have implications for those designing school intervention studies.

Factors Affecting Psychiatry Resident Decision to Pursue Consultation-Liaison Psychiatry or Other Subspecialty Fellowship Training.

BACKGROUND: There is a national shortage of psychiatrists with subspecialty fellowship training, and many fellowship positions are unfilled. OBJECTIVE: We conducted a survey of US psychiatry residents to better understand the motivation to pursue fellowship training and to determine any specific factors that were particularly influential in choosing a fellowship in consultation-liaison (C-L) psychiatry. METHODS: Online surveys were distributed electronically to US general psychiatry residents through the American Association of Directors of Psychiatric Residency Training list server. RESULTS: A total of 219 questionnaires were completed. Interest in fellowship declined during residency training. Most important factors in consideration of fellowship training were lifestyle (89%), finances (69%), and academic opportunities (63%). Specific influential factors were residency experiences, attending staff as a role model, and medical school experiences. Most important discouraging factors were extra training time, financial concerns, and belief that fellowship training was not necessary. Only 30% of residents had outpatient C-L psychiatry experiences. Few residents belonged to any subspecialty organization or attended any subspecialty meeting. Residents interested in C-L psychiatry fellowships had lower expectation of increased salary than other residents. Outpatient practice settings were seen as preferable over inpatient settings by most residents. CONCLUSIONS: Results of this survey suggest that enhancing consultation psychiatry exposure in medical school and residency with strong role models, outpatient C-L psychiatry experiences, facilitating subspecialty organization membership and meeting attendance, emphasizing academic opportunities of fellowship training, and improving remuneration for fellowship-trained psychiatrists might be important factors that could improve recruitment into C-L psychiatry and other psychiatric fellowships.

Implementing Motivational Interviewing for Substance Misuse on Medical Inpatient Units: a Randomized Controlled Trial.

BACKGROUND: General medical hospitals provide care for a disproportionate share of patients who misuse substances. Hospitalization provides a unique opportunity to identify and motivate patients to address their substance misuse. OBJECTIVE: To determine the effectiveness of three strategies for implementing motivational interviewing for substance misuse with general medical inpatients. DESIGN: Type 3 hybrid effectiveness-implementation randomized controlled trial (Clinical Trials.gov: NCT01825057). PARTICIPANTS: Thirty-eight providers (physicians, physician assistants, nurses) from 13 general medical inpatient services, and 1173 of their patients admitted to an academically affiliated acute care hospital. INTERVENTIONS: Implementation strategies included (1) a continuing medical education workshop on detection of substance misuse and provision of a motivational interview; (2) workshop plus bedside supervision (apprenticeship condition); and (3) a workshop plus ability to place a medical order for an interview from a consultation-liaison service (consult condition). MAIN MEASURES: Primary outcomes were the percentage of study-eligible patients who received an interview for substance misuse and the integrity (adherence, competence) of the interviews. The secondary outcome was the percent of patient statements within the interviews that indicated motivation for reducing substance misuse. KEY RESULTS: 20.5% of patients in the consult condition received an interview, compared to 0.8% (Hedge's g = 1.49) and 3.0% (Hedge's g = 1.26) in the respective workshop only and apprenticeship conditions (p < 0.001). Motivational interviews in the consult condition were performed with more fundamental motivational interviewing adherence and competence than the other conditions. Most statements made by patients during the interviews favored reducing substance misuse, with no differences between conditions. CONCLUSIONS: Providers' ability to place an order to have experts from the consultation-liaison service deliver a motivational interview was a more effective implementation strategy than a workshop or apprenticeship method for ensuring motivational interviewing is available to medical inpatients who misuse substances. TRIAL REGISTRY: NCT01825057.

Commercially Available Phototherapy Devices for Treatment of Depression: Physical Characteristics of Emitted Light.

Objective: The purpose of this study was to evaluate key physical properties of commercially available light devices for the treatment of seasonal or nonseasonal depression and to determine whether the devices met clinical criteria, derived from evidence-based clinical guidelines, for generating adequate light at a reasonable distance, over a reasonable field of illumination, and with an adequate degree of user acceptability. Methods: Twelve manufacturers loaned or donated 24 light therapy devices: 16 light boxes, one light column, four light-emitting diode beam devices, and three light visors. Each device was evaluated for spectral power distribution, light dispersion, subjective discomfort from glare, adequacy of diffusion, photopic illuminance (in lumens per square meter [lux]), melanopic illuminance relative to photopic illuminance (efficacy ratio), and blue light hazard relative to melanopic illuminance (protection ratio). Results: Physical properties of emitted light varied widely among devices. Only seven larger light boxes satisfied the three clinical criteria. Some devices advertised as "10,000-lux" devices produced this intensity only at unreasonably close distances, over a restricted field, or with unacceptable glare or unevenness of illumination. Five other devices emitted light with physical properties whose efficacy is less supported by research, although these devices may be useful for some patients. Conclusions: These results should help clinicians identify appropriate devices for patients seeking light therapy for seasonal or nonseasonal depression. Device selection is key to ensuring that patients receive evidence-supported doses of light.

Alcohol and Sedative-Hypnotic Withdrawal Catatonia: Two Case Reports, Systematic Literature Review, and Suggestion of a Potential Relationship With Alcohol Withdrawal Delirium.

BACKGROUND: Withdrawal from alcohol and sedative-hypnotics can be complicated by seizures, hallucinations, or delirium. Withdrawal catatonia is another, less commonly discussed complication that clinicians should appreciate. METHODS: We present a case of alcohol withdrawal catatonia and a case of benzodiazepine withdrawal catatonia and offer a systematic review of previous cases of alcohol or sedative-hypnotic withdrawal catatonia. We outline clinical features that suggest a potential link between withdrawal catatonia and withdrawal delirium. RESULTS: We identified 26 cases of withdrawal catatonia in the literature-all principally with catatonic stupor-with an average age of 56 years (range: 27-92) and balanced prevalence between sexes. Withdrawal catatonia tends to occur only after chronic use of alcohol or sedative-hypnotic agents with a typical onset of 3-7 days after discontinuation and duration of 3-10 days. Withdrawal catatonia is responsive to benzodiazepines or electroconvulsive therapy. Features that suggest a parallel between withdrawal catatonia and withdrawal delirium include time course, neurobiologic convergence, efficacy of benzodiazepines and electroconvulsive therapy, typical absence of abnormal electroencephalographic findings, and phenotypic classification suggested by a recent literature in sleep medicine. CONCLUSION: Alcohol and sedative-hypnotic withdrawal may present with catatonia or catatonic features. The clinical and neurobiologic convergence between withdrawal catatonia and withdrawal delirium deserves further attention. In view of these similarities, we propose that withdrawal delirium may represent excited catatonia: these new viewpoints may serve as a substrate for a better understanding of the delirium-catatonia spectrum.

Circadian Rhythm Disruption in the Critically Ill: An Opportunity for Improving Outcomes.

OBJECTIVES: Circadian rhythms are severely disrupted among the critically ill. These circadian arrhythmias impair mentation, immunity, autonomic function, endocrine activity, hormonal signaling, and ultimately healing. In this review, we present a modern model of circadian disruption among the critically ill, discuss causes of these circadian arrhythmias, review observational and intervention studies of the effects of circadian-rhythm-restoring factors on medical outcomes, and identify needed key trials of circadian interventions in the critically ill. DATA SOURCES: MEDLINE, EMBASE, PsychINFO, Google Scholar through December 2014. STUDY SELECTION: Articles relevant to circadian rhythms, melatonin, and light in the critically ill were selected. DATA EXTRACTION AND DATA SYNTHESIS: Articles were synthesized for this review of circadian arrhythmia and the use of circadian-rhythm-restoring interventions among the critically ill. CONCLUSIONS: Circadian disruption often demonstrates serial degradation: initially, the amplitude attenuates along with delayed circadian phase. With increasing acuity of illness, circadian rhythmicity may be lost entirely. Causes of chronodisruption may be environmental or internal to the patient. In particular, inadequate daytime illumination and nocturnal light pollution disrupt healthy circadian periodicity. Internal causes of circadian arrhythmia include critical illness itself and subjective experience of distress and pain. Observational studies of windowed rooms and real-time ambient lighting have found that physiologic light-dark patterns may support recovery from critical illness. Studies of early morning bright light or evening melatonin agonists have found improved rates of delirium, enhanced sleep, and lower arrhythmia prevalence. The current evidence base emphasizes that lighting and melatoninergic interventions deserve to be tested in full-scale trials.

SAD and the not-so-single photoreceptors.

Research in the last century has demonstrated that light is a critical regulator of physiology in animals. More recent research has exposed the influence of light on human behavior, including the phenomenon of seasonal affective disorder (SAD). Repeated studies have shown that light treatment is effective in this disorder. The molecular mechanism by which the body absorbs the light that has energizing and antidepressant effects is still uncertain. This review presents evidence regarding the role of rod and cone photoreceptors, as well as the role of recently discovered nonvisual neuronal melanopsin-containing photoreceptors. The authors discuss an evolutionary-based theoretical model of humoral phototransduction. This model postulates that tetrapyrrole pigments, including hemoglobin and bilirubin, are blood-borne photoreceptors, regulating gasotransmitters such as carbon monoxide when exposed to light in the eye. Recent studies in an animal model for seasonality provide data consistent with this model. Understanding the molecular mechanisms by which light affects physiology may guide the development of therapies for SAD and other pathologies of circadian and circannual regulation.

Association of smoking with wound complications after cesarean delivery.

OBJECTIVE: To determine whether smoking is an independent risk factor for wound dehiscence after cesarean delivery. METHODS: In this case-control study, medical records were reviewed for all patients with wound dehiscence after cesarean delivery during a 7-month period. Wound dehiscence was defined as separation of wound edges requiring treatment. Three control patients without such complications were randomly selected for each case patient. Univariate associations were assessed using t test or Fisher's exact test; univariate odds ratios (OR) and 95% confidence intervals (CI) were calculated with logistic regression. Multivariate associations were assessed with logistic regression on variables with a univariate association significant at p ≤ 0.10. RESULTS: Of 597 cesarean deliveries, 30 cases (5 %) with wound dehiscence were identified. As individual variables, smoking (46.7 vs. 21.1%, p < 0.01, cases vs. controls), histological chorioamnionitis (27.6 vs. 6.7%, p < 0.01) and preoperative hematocrit (34.0 ± 3.2 vs. 35.4 ± 3.4, p < 0.05) were significantly associated with wound complications. In a multivariate logistic regression model, only smoking (OR 5.32; 95% CI 1.77-15.97, p < 0.01) and histological chorioamnionitis (OR 5.62; 95% CI 1.43-22.11, p < 0.01) were independently associated with wound dehiscence. CONCLUSIONS: Smoking and histological chorioamnionitis are independently associated with wound dehiscence after cesarean delivery.

Proactive psychiatric consultation services reduce length of stay for admissions to an inpatient medical team.

BACKGROUND: Some studies suggest intensive psychiatric consultation services facilitate medical care and reduce length of stay (LOS) in general hospitals. OBJECTIVE: To compare LOS between a consultation-as-usual model and a proactive consultation model involving review of all admissions, rapid consultation, and close follow-up. METHODS: LOS was compared in an ABA design between a 33-day intervention period and 10 similar control periods, 5 before and 5 after the intervention, on an internal medical unit. During the intervention period, a staff psychiatrist met with the medical team each weekday, reviewed all admissions, provided immediate consultation as needed, and followed all cases throughout their hospital stay. RESULTS: Time required for initial case review was brief, 2.9 ± 2.2 minutes per patient (mean ± S.D.). Over 50% of admissions had mental health needs: 20.3% were estimated to require specialist consultation to avoid potential delay of discharge. The consultation rate for the intervention sample was 22.6%, significantly greater than in the control sample, 10.7%. Mean LOS was significantly shorter in the intervention sample, 2.90 ± 2.12 versus 3.82 ± 3.30 days, and the fraction of cases with LOS > 4 days was significantly lower, 14.5% versus 27.9%. A rough cost benefit analysis was favorable with at least a 4.2 ratio of financial benefit to cost. CONCLUSIONS: Psychiatric review of all admissions is feasible, indicates a high incidence of mental health barriers to discharge, identifies more necessary consultations than typically requested, and results in earlier consultation. A proactive consultation model can reduce hospital LOS.

A controlled trial of the Litebook light-emitting diode (LED) light therapy device for treatment of Seasonal Affective Disorder (SAD).

BACKGROUND: Recent research has emphasized that the human circadian rhythm system is differentially sensitive to short wavelength light. Light treatment devices using efficient light-emitting diodes (LEDs) whose output is relatively concentrated in short wavelengths may enable a more convenient effective therapy for Seasonal Affective Disorder (SAD). METHODS: The efficacy of a LED light therapy device in the treatment of SAD was tested in a randomized, double-blind, placebo-controlled, multi-center trial. Participants aged 18 to 65 with SAD (DSM-IV major depression with seasonal pattern) were seen at Baseline and Randomization visits separated by 1 week, and after 1, 2, 3 and 4 weeks of treatment. Hamilton Depression Rating Scale scores (SIGH-SAD) were obtained at each visit. Participants with SIGH-SAD of 20 or greater at Baseline and Randomization visits were randomized to active or control treatment: exposure to the Litebook LED treatment device (The Litebook Company Ltd., Alberta, Canada) which delivers 1,350 lux white light (with spectral emission peaks at 464 nm and 564 nm) at a distance of 20 inches or to an inactivated negative ion generator at a distance of 20 inches, for 30 minutes a day upon awakening and prior to 8 A.M. RESULTS: Of the 26 participants randomized, 23 completed the trial. Mean group SIGH-SAD scores did not differ significantly at randomization. At trial end, the proportions of participants in remission (SIGH-SAD less than 9) were significantly greater (Fisher's exact test), and SIGH-SAD scores, as percent individual score at randomization, were significantly lower (t-test), with active treatment than with control, both in an intent-to-treat analysis and an observed cases analysis. A longitudinal repeated measures ANOVA analysis of SIGH-SAD scores also indicated a significant interaction of time and treatment, showing superiority of the Litebook over the placebo condition. CONCLUSION: The results of this pilot study support the hypothesis that light therapy with the Litebook is an effective treatment for SAD. TRIAL REGISTRATION: Clinicaltrials.gov: NCT00139997.

Assessment and management of patients with psychiatric disorders.

OBJECTIVE: To review key issues in the preoperative assessment of patients with psychiatric disorders: assessment of cognitive capacity, psychiatric history, capacity to give informed consent, and the impact of psychotropic medications or substances of abuse. We also outline a general approach to the psychiatric patient. Our review focuses on those psychiatric conditions and medications most likely to complicate perioperative care. DATA SOURCE: Critical studies and expert reviews in the field, as well as the authors' clinical experience in general hospital psychiatry. CONCLUSIONS: Psychiatric disorders need not unduly complicate perioperative care, but they present certain challenges; a systematic approach as described here will simplify perioperative care of these patients.

Effects of light on low nocturnal bilirubin in winter depression: a preliminary report.

BACKGROUND: The light-absorbing pigments involved in the induction of treatment of winter depression are unknown. It has been proposed that circulating bilirubin serves as a photoreceptor, in part because of its similarity to the chromophore of phytochrome, a primary time-setting plant molecule. METHODS: We measured nocturnal bilirubin levels in nine patients with winter depression, and seven age- and gender-matched normal comparison volunteers. RESULTS: Nocturnal bilirubin levels were lower in patients than in controls (p <.02), increased in both groups during the night (p <.0001), and increased in patients after 2 weeks of morning light treatment (p =.0009), which was accompanied by clinical improvement. CONCLUSIONS: Low nocturnal bilirubin levels may be associated with winter seasonal depression.
