Consultation-liaison psychiatry: stability and change over a 10-year-period

The adjustment disorder is not a wastebasket diagnosis: a grounded theory study of psychiatrists' and psychologists' clinical reasoning

Background: the aim of this study is to understand the diagnostic process undertaken by psychiatrists and psychologists regarding adjustment disorder (AD) in their clinical practice and how they differentiate it from major depressive episode (MDE).Methods: A hermeneutic study using grounded theory techniques was carried out. Semi-structured interviews were conducted with twelve psychiatrists and eight psychologists in Colombia, and transcribed verbatim. Initial line-by-line coding was performed, followed by focused and axial coding to construct categories explaining the professionals' reasoning process.Results: The clinical reasoning of professionals regarding AD was understood through four major categories. (1) Difficulty in addressing the experience of stressful events, as there is a risk of pathologizing and medicalizing them. (2) Mental health diagnoses are necessary but not apodictic. (3) The diagnostic category of AD allows for the description of a fluctuating depressive and anxious syndrome occurring in reaction to a stressful event, whose abnormality criteria are based on intersubjective knowledge of the patient's life history and consequential reasoning regarding the need for professional support. (4) The AD label could potentially protect against overdiagnosis of MDE and overuse of antidepressants. Many clinicians in their practice thus subordinate the diagnosis of MDE to ensuring it is not AD, contrary to what is outlined in diagnostic manuals.Conclusion: This study allowed us to understand the clinical reasoning of psychiatrists and psychologists about AD as a diagnosis that inherently indicates the need to work on coping and intervene in the stressor and should be considered as a diagnostic possibility in the same hierarchy as MDE in reactive syndromes, rather than a residual category.

Objective cognitive functioning in patients with stress-related disorders: a cross-sectional study using remote digital cognitive testing

BACKGROUND

Patients with stress-related mental disorders often report cognitive impairment, but studies investigating objective cognitive impairment in patients with stress-related disorders have produced inconsistent findings.

AIM

The primary aim of this study was to investigate objective cognitive functioning in patients diagnosed with the stress-related disorders adjustment disorder or exhaustion disorder, compared to a healthy normative group. Secondary aims were to conduct subgroup analyses of cognitive functioning between the diagnostic groups and explore associations between self-reported symptoms and cognitive functioning.

METHODS

Cognitive test results on a digitally self-administered cognitive test battery from 266 patients (adjustment disorder, n = 131; exhaustion disorder, n = 135) were cross-sectionally compared with results from a healthy normative group (N = 184 to 692) using one-tailed t-tests. ANOVAs were conducted for subgroup analyses, and regression analyses for associations between self-reported symptoms and cognitive functioning. Effect sizes were calculated.

RESULTS

Patients performed significantly worse than the normative group on all measures with small to moderate effect sizes ranging from d = -.13 to -.57. Those diagnosed with exhaustion disorder performed worse than norms on more measures than did patients with adjustment disorder, but no significant differences between diagnostic groups were found on any measure. Self-reported memory impairment was weakly associated with one of two memory measures. No clear associations between self-reported burnout symptoms and objective cognitive functioning were found.

CONCLUSIONS

This study adds to the literature indicative of small to moderate objective cognitive impairments in patients diagnosed with stress-related mental disorders. Further exploration into mechanisms of cognitive functioning in different populations is needed for development of theoretical models that may explain the weak correlation between self-reported symptoms and objective measures.

History of mental disorder in an ICU and referrals to psychiatry

OBJECTIVE

To describe the prevalence of patients with mental disorders (MD) admitted to the ICU. To compare the clinical characteristics according to the presence of psychiatric history. To review the relevance of the consultations made to Psychiatry.

DESIGN

Retrospective descriptive study.

SETTING

ICU of the General Hospital of the Parc Sanitari Sant Joan de Deu, Sant Boi de Llobregat, Barcelona, Spain.

PATIENTS

Patients admitted between January 2016 and June 2018.

INTERVENTIONS

None.

MAIN VARIABLES OF INTEREST

Severity level (APACHE II), reason for admission, days of admission, days of mechanical ventilation, psychiatric history and reason for psychiatric consultation.

RESULTS

A total of 1,247 patients were included; 194 (15.5%) met MD criteria, their mean age being younger (59 vs 68, P < .001) and with a lower mean score on the APACHE II scale (12 vs 14, P ≤ .003). There were 64 consultations to Psychiatry (5.1% of admissions), 59 of which were in patients with TM (92.1%). Regarding the reasons for the consultation, 22.6% were for attempted suicide, 61.3% for pharmacological adjustment, 11.3% to rule out mental disorder, and 4.8% for competence assessment. The probability of a consultation being carried out while it was indicated was 89.1%, while the probability of not carrying it out when it was not indicated was 99.4%.

CONCLUSIONS

This study supports the need to expand the specific recommendations for consultation to Psychiatry, beyond the assessment after a suicide attempt, since a large percentage (77.5%) of the pertinent consultations were for other reasons.

Clinical Profile and Length of Hospital Stay in a Sample of Psychogeriatric Patients Referred to Consultation Liaison Psychiatric Unit

Background and objectives: There has been a recent increase in older patients admitted to general hospitals. A significant percentage of hospitalized older patients are ≥75 years old, which differ from the patients aged 65 to 74 years old in terms of functional status at patient discharge. This study aims to compare sociodemographic, clinical features, and factors associated with length of hospital stay in youngest-old and oldest-old populations of inpatients referred to the consultation liaison psychiatry unit. Material and methods: This is an observational, cross-sectional, retrospective, and comparative study. We obtained data from a sample of 1017 patients (≥65 years) admitted to a general hospital and referred from different services (medicine, surgery, etc.) to the consultation liaison psychiatry unit. The sample was divided into two groups of patients: youngest-old (65–74 years) and oldest-old (≥75 years). Psychiatric evaluations were performed while the patients were on wards at the hospital. Psychopharmacs were started as needed. A comparative analysis was carried out and predictive factors related to length of hospital stay were calculated. Results: The reference rate to consultation liaison psychiatry unit was 1.45% of the total older patients hospitalized. Our study demonstrates differences between the groups of older people: the oldest-old group were mainly female (p < 0.001), had more previous psychiatric diagnoses (p < 0.001), physical disabilities (p = 0.02), and neurocognitive disorders (p < 0.001), they used more antipsychotics (p < 0.001), and more frequently had a discharge disposition to a nursing home (p = 0.036). The presence of physical disability (beta = 0.07, p < 0.001) and logtime to referral to consultation liaison psychiatry unit (beta = 0.58, p < 0.001) were associated with increased length of hospital stay. Conclusions: Youngest-old and oldest-old people should be considered as two different types of patients when we consider clinical features. The time to referral to consultation liaison psychiatry unit seems to be a relevant factor associated with length of hospital stay.

[Diagnosis and treatment of adjusment disorder in primary care]

Adjustment disorder (AD) corresponds to the combination of affective, cognitive and behavioral symptoms that appear after a stressful event. It is a frequent reason for consultation in primary care and is one of the most common diagnoses in suicide attempts attended in the emergency department. Its essential feature is that the symptoms must appear in direct relation to an event perceived as stressful, so it tends to be transitory if the event ceases or the patient adapts. The mainstay of treatment are psychosocial interventions, aimed at modifying the event or its consequences, supporting adaptation and optimizing resources to cope with the event. However, prescription of psychotropic drugs is favored in practice, when its use should be limited to symptomatic relief. This highlights the need to properly identify and treat it. This article presents the strategies for diagnosis and treatment of AD in primary care.

Impact of the addition of a clinical pharmacist to a community hospital psychiatric consult liaison team

The objective of this data analysis was to assess the impact of the addition of a clinical psychiatric pharmacist to a community hospital inpatient psychiatric consult liaison team. Consult liaison psychiatry deals with medically ill patients in general hospital settings and involves the timely recognition and treatment of mental health conditions while coordinating with other medical providers. Each patient consulted to the psychiatry team was reviewed by the clinical pharmacist. Recommendations made by the clinical pharmacist were tracked over a 9-month period. During that time frame, 596 opportunities for intervention were identified. The largest proportion of identified opportunities for intervention were related to admission medication reconciliation, equating to roughly 30%. Optimization of safe medication use had the second largest number of opportunities for intervention at approximately 27%. Additional data, such as time spent on patient care, reason for consultation, and number of accepted recommendations based on medication class/type of intervention, were collected.

Psychiatric Consultations in General Hospitals: A Scoping Review

Context: The rapid growth of psychiatric disorders requires psychiatric consultations to be provided on a greater scale, particularly for hospitalized patients. Objectives: The aim of this study was to evaluate the extent of psychiatric consultation requests in general hospitals and to identify potential gaps in the literature. Evidence Acquisition: This scoping review was based on relevant research published in Web of Science, Scopus, PubMed, Embase, and Cochrane (1977- Dec 2019). The collected literature was closely examined prior to selecting the applicable studies by means of peer review. Data were summarized within a framework of themes comprised of psychiatric consultation, prevalence of psychiatric disorders, hospital departments, diagnosis of psychiatric disorders, and nature of research prior to theoretical classification and tabulation. Results: Ultimately, 22 studies were included in this scoping review. Requests for psychiatric consultations were highest in Austria and Italy, with 22.6% and 13.6% of cases, respectively. The majority of requests were from internal and surgical departments. Consultations were requested more frequently for female patients compared to male patients. mood disorders and substance use disorder were the most diagnostic reports. Conclusions: Taking into consideration the prevalence of psychiatric disorders in patients suffering from physical illnesses, the referral rate results were considerably low. Although the frequency of psychiatric consultation reports vary widely between countries. As we limited the review to articles written in English, this may be due to selection bias. In this review, we identified that methodological differences and the use of different diagnostic criteria are major gaps that limit a definitive statistical comparison between studies.

The effect of a hospital liaison psychiatry service on inpatient lengths of stay: interrupted time series analysis using routinely collected NHS hospital episode statistics

BACKGROUND

The purpose of the study was to determine whether establishment of a specific liaison psychiatry service designed to offer a rapid response with facilitated hospital discharge led to reduced acute hospital length of inpatient stay.

METHODS

We used interrupted time series based upon routine NHS data from secondary care service in two acute general hospitals, for all adult (16+ years) inpatient admissions (114,029 inpatient spells representing 70,575 individual patients) over 3 years.

RESULTS

Length of stay reduced over time in both hospitals. Against a background of falling length of stay across the study period, there was no discernible effect of the rapid access/early discharge liaison service on length of stay, either as a step change or linear decline. This finding held for all patients and for those over 65 years and those discharged with a mental health diagnosis.

CONCLUSIONS

Using routine NHS data for a whole hospital it was not possible to replicate a previous report that a rapid access liaison psychiatry service for inpatients produces substantial reductions in length of stay, and commissioners of services should be cautious of claims to the contrary. Further research to determine if there is an effect for sub-groups will require major improvements in the way co-morbid mental disorders are coded in NHS practice.

Why are hospital doctors not referring to Consultation-Liaison Psychiatry? - a systemic review

BACKGROUND

Consultation-Liaison Psychiatry (CLP) is a subspecialty of psychiatry that provides care to inpatients under non-psychiatric care. Despite evidence of benefits of CLP for inpatients with psychiatric comorbidities, referral rates from hospital doctors remain low. This review aims to understand barriers to CLP inpatient referral as described in the literature.

METHODS

We searched on Medline, PsychINFO, CINAHL and SCOPUS, using MESH and the following keywords: 1) Consultation-Liaison Psychiatry, Consultation Liaison Psychiatry, Consultation Psychiatry, Liaison Psychiatry, Hospital Psychiatry, Psychosomatic Medicine, the 2) Referral, Consultation, Consultancy and 3) Inpatient, Hospitalized patient, Hospitalized patient. We considered papers published between 1 Jan 1965 and 30 Sep 2015 and all articles written in English that contribute to understanding of barriers to CLP referral were included.

RESULTS

Thirty-five eligible articles were found and they were grouped thematically into three categories: (1) Systemic factors; (2) Referrer factors; (3) Patient factors. Systemic factors that improves referrals include a dedicated CLP service, active CLP consultant and collaborative screening of patients. Referrer factors that increases referrals include doctors of internal medicine specialty and comfortable with CLP. Patients more likely to be referred tend to be young, has psychiatric history, live in an urban setting or has functional psychosis.

CONCLUSION

This is the first systematic review that examines factors that influence CLP inpatient referrals. Although there is research in this area, it is of limited quality. Education could be provided to hospital doctors to better recognise mental illness. Collaborative screening of vulnerable groups could prevent inpatients from missing out on psychiatric care. CLP clinicians should use the knowledge gained in this review to provide quality engagement with referrers.

Opening the 'black box': liaison psychiatry services and what they actually do

Aims and method To develop a simple, pragmatic typology to characterise the nature of liaison interventions delivered by a liaison service in a National Health Service setting. We carried out a retrospective electronic case-note review of referrals to a ward-based liaison psychiatry service. Results Three hundred and forty-four patients were referred to the service over a 12-month period. Ten different types of liaison interventions were identified, with the most common interventions being diagnosis (112 patients, 32.6%), medication management (57 patients, 16.6%), risk assessment and treatment (56 patients, 16.3% each). Mental Health Act work accounted for the greatest number of contacts per patient (median 7). Clinical implications There are inherent limitations in any single-site observational study, as site-specific results cannot be generalised to other liaison services. The intervention categories we developed, however, are easy to use and will provide a way of comparing and benchmarking the range of interventions delivered by different liaison psychiatry services.

Comparison of consultation-liaison psychiatry services for inner-city, district or regional general hospitals using a common tool: Does one size fit all?

OBJECTIVE

Consultation-liaison psychiatry (CLP) services vary in terms of structure, function and responsiveness. It is not known whether evaluation measurements can be meaningfully compared across different CLP services to assess value and efficiency. The aim was to develop and test a common tool for measuring process and outcome measures in CLP.

METHODS

A data collection tool was developed using the literature and consultation with CLP clinicians. The tool was used to prospectively gather referral data, response times, health utilisation data and functional outcomes for individuals referred over seven months to three different CLP teams, servicing inner city, district and regional areas.

RESULTS

The structure, staffing, liaison attachments and scope of practice varied between the services. The regional CLP service attended seven hospitals and had the highest referral rate and largest inpatient population pool. The three services received referrals for similar reasons and made similar diagnoses. Multimodal management was the norm, and CLP facilitated follow-up arrangements upon discharge. Only the district CLP service saw all emergency referrals within an hour. Age and need for an interpreter did not affect response times.

CONCLUSION

Despite local differences in geography, CLP roles, hospital and community mental health service pathways and patient populations, the CLP data collection tool was applicable across sites. Staff resourcing and referral demand are key determinants of CLP response times.

Consultation-Liaison Psychiatry-from theory to clinical practice: an observational study in a general hospital

BACKGROUND

To investigate significant association between various clinical and extra-clinical factors brought out the activities of Consultation-Liaison Service.

METHODS

Data from all psychiatric consultations for patients admitted to the Perugia General Hospital and carried out over a 1-year period (from July the 1st 2009 to June the 30th 2010) were collected by a structured clinical report including: socio-demographic features, features of referrals, features of back-referrals. T-test, Mann-Whitney U-test, χ(2)-test and Fischer's were statistically used.

RESULTS

1098 consultations were performed. The consultations carried out the Emergency Unit were excluded from the study. The type and the reasons for the referrals were discussed such as the ICD-10 diagnosis and the liaison interventions too. Significant associations emerged between gender and: social status and occupation (p < 0.05 and p < 0.01 respectively). Clinical sector related with reason for referral (p < 0.01), type of consultation (p < 0.01), liaison investigations (p < 0.01) and long-term treatment plan after hospital discharge (p < 0.01). The ICD-10 psychiatric diagnosis (Schizophrenia, Affective Syndrome and Neurotic-StressSomatoform Syndrome) was associated with social status (p < 0.01), social condition (p < 0.01), consultation type (p < 0.01), advice (p < 0.01) and reason for consultation (p < 0.01).

CONCLUSIONS

The need for better physical and psychological investigation is confirmed in order to promote not only disease remission but overall wellbeing.

Relationship between timeliness of contact and length of stay in older and younger patients of a consultation-liaison psychiatry service

Aim and methods The aims were to determine whether the timeliness of contact with a consultation-liaison psychiatry (CLP) service is associated with shorter lengths of stay (LOS), whether this relationship persists for stays greater than 4 days and whether this association varies with age. The length of stay was correlated with the time from admission to contact with the service (the referral lag (REFLAG)), and the REFLAG's proportion of length of stay (REFLAG/LOS) for all 140 in-patients, those with stays greater than 4 days, and for those under and over 65 years. Results The length of stay was significantly correlated with referral lag and logREFLAG/logLOS for all patients and for patients with stays greater than 4 days. The correlations remained significant for both age groups, but were stronger in the younger group. Clinical implications Timeliness of contact with CLP was associated with shorter length of stay, particularly in younger patients. Psychiatric factors influencing length of stay in older patients should be studied by CLP services.

Secondary analysis and literature review of community rehabilitation and intermediate care: an information resource

Background and design

This research was based on a reanalysis of a merged data set from two intermediate care (IC) projects in order to identify patient characteristics associated with outcomes [Nancarrow SA, Enderby PM, Moran AM, Dixon S, Parker SG, Bradburn MJ,et al.The Relationship Between Workforce Flexibility and the Costs and Outcomes of Older Peoples’ Services (COOP). Southampton: National Institute for Health Research (NIHR) Service Delivery and Organisation (SDO); 2010 and Nancarrow SA, Enderby PM, Ariss SM, Smith T, Booth A, Campbell MJ,et al.The Impact of Enhancing the Effectiveness of Interdisciplinary Working (EEICC). Southampton: NIHR SDO; 2012]. Additionally, the impact of different team and staffing structures on patient outcomes and service costs was examined, when possible given the data sets, to enable identification of the most cost-effective service configurations and change over time with service provision. This secondary analysis was placed within updated literature reviews focused on the separate questions.

Research objectives

(1) To identify those patients most likely to benefit from IC and those who would be best placed to receive care elsewhere; (2) to examine the effectiveness of different models of IC; (3) to explore the differences between IC service configurations and how they have changed over time; and (4) to use the findings above to develop accessible evidence to guide service commissioning and monitoring.

Setting

Community-based services for older people are described in many different ways, among which are IC services and community rehabilitation. For the purposes of this report we call the services IC services and include all community-based provision for supporting older people who would otherwise be admitted to hospital or who would require increased length of stay in hospital (e.g. hospital at home schemes, post-acute care, step-up and step-down services).

Participants

The combined data set contained data on 8070 patient admissions from 32 IC teams across England and included details of the service context, costs, staffing/skill mix (800 staff), patient health status and outcomes.

Interventions

The interventions associated with the study cover the range of services and therapies available in IC settings. These are provided by a wide range of professionals and care staff, including nursing, allied health and social care.

Outcome measures

(1) Service data – each team provided information relating to the size, nature, staffing and resourcing of the services. Data were collected on a service pro forma. (2) Team data – all staff members of the teams participating in both studies provided individual information using the Workforce Dynamics Questionnaire. (3) Patient data – patient data were collected on admission and discharge using a client record pack. The client record pack recorded a range of data utilising a number of validated tools, such as demographic data, level of care (LoC) data, therapy outcome measure (TOM) scale, European Quality of Life-5 Dimensions (EQ-5D) questionnaire and patient satisfaction survey.

Results

(1) The provision of IC across England is highly variable with different referral routes, team structures, skill mix and cost-effectiveness; (2) in more recent years, patients referred to IC have more complex needs associated with more severe impairments; (3) patients most likely to improve were those requiring rehabilitation as determined by levels 3, 4 and 5 on the LoC (> 40% for impairment, activity and participation, and > 30% for well-being as determined on the TOM scale); (4) half of all patients with outcome data improved on at least one of the domains of the TOM scale; (5) for every 10-year increase in age there was a 6% decrease in the odds of returning home. The chance of remaining or returning home was greater for females than males; (6) a high percentage of patients referred to IC do not require the service; and (7) teams including clinical support staff and domiciliary staff were associated with a small relative improvement in TOM impairment scores when compared with other teams.

Conclusions

This study provides additional evidence that interdisciplinary teamworking in IC may be associated with better outcomes for patients, but care should be taken with overinterpretation. The measures that were used within the studies were found to be reliable, valid and practical and could be used for benchmarking. This study highlights the need for funding high-quality studies that attempt to examine what specific team-level factors are associated with better outcomes for patients. It is therefore important that studies in the future attempt empirically to examine what process-level team variables are associated with these outcomes.

Wand A. Quality indicators for a consultation-liaison psychiatry service

Purpose

– Consultation-liaison psychiatry (CLP) researchers have not yet developed accepted quality indicators to measure efficiency or effectiveness. The purpose of this paper is to combine objective and subjective quality indicators to assess hospital-based CLP service utilisation, efficiency and effectiveness.

Design/methodology/approach

– Service utilisation rate was calculated over the service's first four years. Patient characteristics and objective quality indicators relating to response timeliness in 2012 were examined. Totally, 41 staff and 52 consecutive patients completed evaluation surveys to subjectively evaluate effectiveness.

Findings

– The utilisation rate increased initially and then slightly declined to 1.03 per cent of all hospital admissions. In 2012, 91.5 per cent were seen on the same referral day and 99.4 per cent by the next day. The benchmark for urgent referrals was not met (77.4 per cent). Patients rated involvement with the CLP service a positive experience (90 per cent), but were less clear about follow-up plans (68 per cent). Staff believed that the service improved the patients’ hospital course (98 per cent) and was communicated well (93-95 per cent). Only 63 per cent agreed that relevant CLP education was provided and 76 per cent rated follow-up plans as clear.

Originality/value

– This CLP service was evaluated by measuring utilisation rates, referral response timeliness and consumer feedback. Referral to contact time is a useful objective quality indicator but should be combined with subjective yet standardised measures surveying service recipients (patients and referring staff) to be comprehensive and meaningful.

Reasons for referral and consultation liaison psychiatry diagnoses

Objectives:

Focused management strategies, including effective distribution of available resources is dependent on ongoing analysis of referral type in any liaison psychiatry consultation service. This survey sought to measure rate of diagnoses in an Irish liaison psychiatry consultation service, and compare the results with other similar services.

Method:

A survey of referral reasons and diagnoses was performed on all patients presenting to a Dublin based inpatient liaison psychiatry consultation service over two six month periods. The results were subsequently compared with other similar international studies.

Results:

Commonest referral reasons were for depressive disorders, while commonest diagnoses included alcohol related disorders, depressive disorders, and delirium, with notably higher rates of alcohol related disorders than in other similar international studies.

Conclusions:

This study provides valuable information for referral reasons and diagnoses present in an Irish liaison psychiatry consultation service. The differences noted between diagnoses in our study and other international studies, as well as some of the difficulties in establishing these diagnoses, are discussed.

Perioperative psycho-educational intervention can reduce postoperative delirium in patients after cardiac surgery: a pilot study

OBJECTIVE

Postoperative delirium after cardiac surgery is associated with many consequences such as poorer functional recovery, more frequent postoperative complications, higher mortality, increased length of hospital stay, and higher hospital costs. The aim of this study was to evaluate the efficacy of perioperative psycho-educational intervention in preventing postoperative delirium in post cardiac surgery patients.

METHOD

We conducted a comparative retrospective study between 49 patients who had received perioperative psycho-educational intervention and 46 patients who had received standard care. The primary outcome was the incidence of postoperative delirium. Secondary outcomes included length of ICU stay, and severity and duration of postoperative delirium among the patients who had developed delirium.

RESULTS

The incidence of postoperative delirium was significantly lower in the intervention group than that in the control group (12.24% vs. 34.78%, P = 0.009). Among the patients who had developed postoperative delirium, there was no statistical difference between the two groups regarding secondary outcomes.

CONCLUSIONS

Our results show that the patients who received perioperative psycho-educational intervention were associated with a lower incidence of postoperative delirium after cardiac surgery than those who received standard care. Clinicians would be able to implement this psycho-educational intervention as part of routine practice to reduce delirium.

Diagnosis of adjustment disorder: reliability of its clinical use and long-term stability

BACKGROUND

Adjustment disorder is a common diagnosis in mental health services. However, the diagnostic reliability and stability of this nosological construct are unclear.

SAMPLING AND METHODS

Clinical chart records of patients who had been discharged with a clinical diagnosis of adjustment disorder were re-evaluated by two independent raters using ICD-10 criteria. On the basis of the chart material, the frequency of readmissions and diagnostic changes were recorded.

RESULTS

Of 142 patients with a clinical diagnosis of adjustment disorder, only 91 (64.1%) retrospectively met ICD-10 criteria for this diagnosis. Eighteen of these 91 patients (19.8%) were readmitted to a mental health hospital within a 5-year period and 9 (9.9%) showed a diagnostic change at readmission, 5 of them to substance use disorders (5.5%).

CONCLUSIONS

The dramatic divergence between the clinical diagnosis and ICD-10 criteria challenges the validity and usefulness of the current nosological concept of adjustment disorder.

Medical inpatients' adherence to outpatient psychiatric aftercare: a prospective study of patients evaluated by an inpatient consultation liaison psychiatry service

OBJECTIVE

This study sought to determine whether patients on psychiatric medication evaluated by inpatient consultation psychiatrists followed up with psychiatric aftercare and continued psychiatric medication 8 weeks post-discharge. Barriers to care and their effect on aftercare follow-up were assessed.

METHOD

This was a prospective study of a consecutive sample of adults who received a psychiatric consultation and were prescribed psychotropic medication during hospitalization on the general medical or surgical inpatient units at the University of Maryland Medical Center. Baseline information was collected from 36 patients who received an inpatient psychiatric consultation and were: (1) prescribed psychiatric medications; and (2) discharged to home. Follow-up data was collected from 21 (58.3%) of these patients 8 weeks post-discharge.

RESULTS

Of 36 patients who provided baseline data, 93% recognized they had a psychiatric disorder, 90% recognized the importance of taking psychiatric medication, and 80% recognized the importance of psychiatric aftercare. Aftercare recommendations were included in only 33% of patient discharge instructions. Of 21 patients providing follow-up data, 57% reported receiving psychiatric aftercare. Patients who did not receive psychiatric aftercare were significantly more likely to be at risk for poor literacy (88.9% vs. 33.3% Fisher's exact test = 0.024) and were less often given psychiatric aftercare instructions at discharge (22% vs. 42%).

CONCLUSIONS

Poor communication of aftercare instructions as well as poor literacy may be associated with lack of psychiatric aftercare. Consultation psychiatrists should assess literacy and insure aftercare information is provided to patients.

Service use in consultation-liaison psychiatry: guidelines for baseline staffing

OBJECTIVE

The aim of this study was to determine how referrals and clinical activity in consultation-liaison psychiatry (C-L) vary according to unit type and size, length of stay and psychiatric diagnosis, and to use these data to inform recommendations for the minimum levels of staffing required to conduct consultations in a general hospital.

METHOD

Data were collected across three urban teaching hospitals over a 5-year period. The data included hospital admission data, referrals, psychiatric diagnosis, clinical contact time, clinical equivalent full time (EFT) and a measure of 'busyness'.

RESULTS

Mean clinical staffing was 0.84 EFT per 100 beds. Services received a mean of 2.4 referrals per 100 hospital admissions. On average, each referral generated 3.9 contacts and a total contact time of 2.6 hours. The contact time was greater in patients with multiple psychiatric diagnoses as compared with a single or no diagnosis.

CONCLUSION

In order to provide a minimum level of service for consultations to the expected range of serious and immediate psychiatric disorders present in the general hospital, a C-L service requires about 1.0 clinical EFT per 100 beds. For services to be able to address more complex elements of illness behaviour, provide education, conduct research, contribute to comprehensive care in specialist areas and undertake other liaison activities, greater and more multi-disciplinary EFT is required.

Adjustment disorders: the state of the art

Adjustment disorders are common, yet under-researched mental disorders. The present classifications fail to provide specific diagnostic criteria and relegate them to sub-syndromal status. They also fail to provide guidance on distinguishing them from normal adaptive reactions to stress or from recognized mental disorders such as depressive episode or post-traumatic stress disorder. These gaps run the risk of pathologizing normal emotional reactions to stressful events on the one hand and on the other of overdiagnosing depressive disorder with the consequent unnecessary prescription of antidepressant treatments. Few of the structured interview schedules used in epidemiological studies incorporate adjustment disorders. They are generally regarded as mild, notwithstanding their prominence as a diagnosis in those dying by suicide and their poor prognosis when diagnosed in adolescents. There are very few intervention studies.

Adjustment disorder: epidemiology, diagnosis and treatment

Adjustment disorder was introduced into the psychiatric classification systems almost 30 years ago, although the concept was recognized for many years before that. In DSM-IV, six subtypes are described based on the predominant symptoms, but no further diagnostic criteria are offered to assist the clinician. These are common conditions, especially in primary care and in consultation liaison psychiatry, where the prevalence ranges from 11% to 18% and from 10% to 35%, respectively. Yet they are under-researched, possibly due to the failure of some of the common diagnostic tools to allow for the diagnosis of adjustment disorder. Among the tools that incorporate adjustment disorder, the concordance between the clinical and interview diagnosis is very poor, with the diagnosis being made more commonly in clinical practice than the diagnostic tools allow for. Adjustment disorder is found in all cultures and in all age groups. The presence of a causal stressor is essential before a diagnosis of adjustment disorder can be made, while the symptoms vary and include those that are found in other common psychiatric disorders. It is also important to distinguish adjustment disorder from normal reactions to stressful events. Adjustment disorders are difficult to distinguish from normal responses to life's stressors, while the distinction from major depression also poses a classificatory conundrum since both are conceptually different. Adjustment disorder is a diagnosis based on the longitudinal course of symptoms in the context of a stressor, while a diagnosis of major depression is a cross-sectional one based on symptom numbers. Treatments consist mainly of brief interventions, while pharmacotherapy is limited to the symptomatic management of anxiety or insomnia. There are no robust studies demonstrating benefits from antidepressants. However, the number of studies of either type of intervention is very limited.

A descriptive study of a unique multi-ethnic consultation-liaison psychiatry service in Honolulu, Hawaii

OBJECTIVE

To provide a descriptive characterization of the CL Psychiatry service at a major medical center in Honolulu, Hawaii. We hypothesized differing demographic trends than seen nationally and internationally, an increasing prevalence of elderly and substance abusing patients, and increasing consultation requests related to these issues.

METHODS

Retrospective data was gathered from 180 randomly selected patient records, identified as having a request for inpatient psychiatric consultation on the medical-surgical floors during identical 3-month periods in 2000 and 2005. Descriptive statistics were calculated. Chi-square and ANOVA were used to compare differences across time.

RESULTS

There were no significant differences by age, reason for referral, or diagnoses between the 2 years. Patients age 65 years and older accounted for only 16.6% of the consults. Caucasians accounted for 45.6% of consultations despite low prevalence rates in the population. Hawaiian/Pacific Islander (15%), Japanese (12.5%), Filipino (5.6%), and other Asians (10.6%) accounted for the majority of remaining patients. Depression/anxiety (27.4%), alcohol/drugs (21.8%), and agitation/ psychosis (20.5%) were the most frequent reasons for consultation. Substance use (32.5%), mood (16%), and cognitive (14.1%) disorders were the top diagnoses.

CONCLUSIONS

As expected, the patient demographic data reflects a unique patient population served by the QMC CL service. Much of the consultation process, diagnoses, and treatment, however, are in line with our Mainland counterparts. There were no major differences in trends over time.

Adjustment Disorder: epidemiology, diagnosis and treatment

BACKGROUND

Adjustment Disorder is a condition strongly tied to acute and chronic stress. Despite clinical suggestion of a large prevalence in the general population and the high frequency of its diagnosis in the clinical settings, there has been relatively little research reported and, consequently, very few hints about its treatments.

METHODS

the authors gathered old and current information on the epidemiology, clinical features, comorbidity, treatment and outcome of adjustment disorder by a systematic review of essays published on PUBMED.

RESULTS

After a first glance at its historical definition and its definition in the DSM and ICD systems, the problem of distinguishing AD from other mood and anxiety disorders, the difficulty in the definition of stress and the implied concept of 'vulnerability' are considered. Comorbidity of AD with other conditions, and outcome of AD are then analyzed. This review also highlights recent data about trends in the use of antidepressant drugs, evidence on their efficacy and the use of psychotherapies.

CONCLUSION

AD is a very common diagnosis in clinical practice, but we still lack data about its rightful clinical entity. This may be caused by a difficulty in facing, with a purely descriptive methods, a "pathogenic label", based on a stressful event, for which a subjective impact has to be considered. We lack efficacy surveys concerning treatment. The use of psychotropic drugs such as antidepressants, in AD with anxious or depressed mood is not properly supported and should be avoided, while the usefulness of psychotherapies is more solidly supported by clinical evidence. To better determine the correct course of therapy, randomized-controlled trials, even for the combined use of drugs and psychotherapies, are needed vitally, especially for the resistant forms of AD.

Changes to inpatient consultation-liaison psychiatry service delivery over a 7-year period

OBJECTIVE

The aim of this paper was to examine the effect of changes to a consultation-liaison (C-L) service at Maroondah Hospital on referral and service delivery patterns across a period of 7 years. There is no national benchmarking of C-L service. Local services respond to local political and service demands. There have been significant changes to the C-L service at Maroondah Hospital between 1999 and 2006. During the intervening years, psychogeriatric referrals have been included and gazetting of general hospital beds has resulted in detention of patients under the Mental Health Act (MHA).

METHOD

Clinical audit data from assessments by the C-L service during the above period were entered into a database and analysed.

RESULTS

The annual referral rate increased as did the mean age of referred patients. The main reason for referral changed from suicide evaluation and history of psychotic symptoms to depression. Referral lag time did not change significantly. A higher proportion of patients received a single consultation and a greater number required psychiatric inpatient care.

CONCLUSION

The nature of referral changed towards older, sicker patients and away from younger, suicidal patients which, together with an increased referral rate, significantly increased demand on available resources.

The adjustment disorders: the conundrums of the diagnoses

This article discusses the conundrums and the dilemmas of the conceptual framework of the diagnoses of the adjustment disorders (ADs). The psychiatric diagnoses that arise between normal behavior and the major psychiatric morbidities constitute the problematic subthreshold disorders. These subthreshold entities are also juxtaposed between problem-level diagnoses and more clearly defined major disorders. They present important taxonomic and diagnostic dilemmas in that they are often poorly defined, overlap with other diagnostic groupings, and have indefinite symptomatology. ADs were designed as a "wild card" to allow the coding of a psychiatric "diagnosis" for work done by psychiatrists and other mental health care specialists when the patient's symptoms do not reach the criterion of a major mental disorder. It is therefore not surprising that issues of reliability and validity prevail. The issues of diagnostic rigor and clinical utility seem at odds for the AD. Clinicians need a wild card, and field studies need to use reliable and valid concepts of AD and assessments instruments to determine more exact specification of the parameters of the diagnosis. Finally, appropriate and timely treatment is essential for patients with AD so that their symptoms do not worsen; their important relationships are not further impaired; or their capacity to work, study, or be active in their essential interpersonal pursuits is not compromised.

Adjustment disorders as stress response syndromes: a new diagnostic concept and its exploration in a medical sample

OBJECTIVE

Adjustment disorders (AD) are an ill-defined category in the present diagnostic nomenclature. We propose a new diagnostic model that describes AD as particular forms of stress response syndrome, in which intrusions, avoidance of reminders and failure to adapt are the central processes and symptoms. In line with the existing classification, the description of AD subtypes is included. Backgrounds on existing psychopathological models of stress response disorders are outlined.

METHODS

Data from a clinical sample of patients with an automatic implantable cardioverter defibrillator (n = 160, mean age 63 years, 90% males) are investigated.

RESULTS

The items tapping the individual symptoms meet psychometric requirements for diagnostic applications. The diagnostic algorithm chosen indicates a 17% prevalence of AD in the sample. The subtype most commonly diagnosed is AD with mixed emotional features (41%). In a subsample, diagnostic sensitivity was 0.58 and specificity 0.81 in relation to traditional AD cases diagnosed by the Structured Clinical Interview for DSM-IV. By applying the most strongly conservative exclusion rule analogous to the Structured Clinical Interview for DSM-IV, the AD prevalence was reduced to 9%.

CONCLUSION

The new AD concept is theory driven and shows methodological soundness. Its application to further samples is recommended.

Consultation-liaison psychiatry services to nursing homes

OBJECTIVE

The aim of the present paper is to review current opinion relating to the provision of mental health consultation to nursing homes, and to provide recommendations for future research.

METHOD

The current literature pertaining to consultation-liaison psychiatry within nursing homes was reviewed.

RESULTS

There is a paucity of well-designed empirical studies of mental health service provision to Australian nursing homes. This is of particular concern given the ageing Australian population and the prevalence of psychiatric symptoms in nursing home residents. Psychiatric consultation and liaison to nursing homes may result in reduced need for crisis intervention, improved use of behavioural management strategies for the symptoms associated with dementia, and reduced nursing home staff stress and burnout.

CONCLUSIONS

Further research is required to evaluate the costs and benefits of providing regular mental health services to nursing homes in Australia, particularly in rural areas. Future service development should be complemented by methodologically sound evaluation.

Models and patterns of service in child and youth consultation-liaison services

OBJECTIVE

The aim was to examine referral pathways to child and youth consultation-liaison (C-L) services to identify patterns associated with demographic characteristics of patients, referral sources, the presenting problem and models of service.

METHOD

A case record review with a cross-sectional design. Data were extracted from the records of all patients referred to the C-L service for a 3 month period.

RESULTS

Adolescents were more likely to access mental health services through informal liaison services. Medical specialty areas that were inclusive of nursing and allied health, in both the request for service and initial response to the request, had higher frequencies of referral. There was no difference between the disciplines of medicine and social work in the frequency of referrals. However, medicine, social work and nursing differed in the number of staff who initiated the request for consultation, and the types of problems that were presented as reasons for referral.

CONCLUSIONS

Inclusive multidisciplinary models may facilitate the development of service relationships in paediatric hospital settings, due to the stability of staffing arrangements. The wider participation of allied health and nursing staff within paediatric hospitals may extend opportunities for the identification of mental health problems and enhance timely management of referrals.

Development of a Taiwanese computerized database for psychiatric consultation in a general hospital

OBJECTIVE

The aim of this study was to evaluate the applicability of a modified questionnaire in psychiatric consultation and a new computerized software at one general hospital in Taiwan.

METHOD

The Micro-Cares Clinical Information System for Consultation/Liaison Psychiatry (CISCL), an English language-based patient management application, has multiple clinical variables that were translated into Mandarin Chinese. The Mandarin Chinese version of the Micro-Cares Questionnaire (MCMQ) was further modified after extensive testing and clinical use by two staff psychiatrists and eight senior resident doctors. In addition, the structure of the Mandarin Chinese version of the Micro-Cares CISCL Program (MCMP) was created for direct information entry through a specialized Microsoft Access-based support module.

RESULTS

The MCMQ has been adapted to regular medical practice. Up to 66% of the consultation cases (618/913 patients) were recorded in 2003. Among those registered, 519 (84%) received psychiatric diagnoses. Eight of the 10 participants evaluated agreed that the MCMQ was clinically applicable.

CONCLUSION

MCMQ and MCMP have been routinely applied in the clinical, administrative, research and educational services of our psychiatric consultation.

Redevelopment of a consultation-liaison service at a tertiary paediatric hospital

OBJECTIVE

This paper aims to describe the way a multidisciplinary team set out to redevelop a consultation-liaison (C-L) service at a tertiary paediatric hospital.

METHOD

The activities and processes in which the team members engaged were documented within a continuous quality improvement cycle. These activities included literature review, analysis of referral patterns, consultation with extant services, survey of referral sources and consultation with other tertiary paediatric services.

RESULTS

The outcomes of these initiatives were integrated into a re-formulated multidisciplinary team model dedicated to providing C-L services to the paediatric hospital. Significant challenges identified in the initial process were ongoing issues with caseload management and clarification of boundary demarcations.

CONCLUSION

There has been a gradual acceptance of the new C-L service by medical staff. The structure has resulted in a focused and coordinated C-L team that has contributed to innovations in the C-L process within the hospital.

Psychiatric Diagnoses of 901 Inpatients Seen by Consultation-Liaison Psychiatrists at an Academic Medical Center in a Managed Care Environment

The authors reviewed the diagnoses from all inpatient psychiatric consultations conducted by faculty psychiatrists during calendar year 2001 (N = 901) at an academic medical center In about 25% of the consultations, multiple psychiatric diagnoses were made. The most frequent diagnosis groups were mood (40.7%), cognitive (32.0%), and substance use disorders (18.6%). Among 671 consultations in which only one diagnosis was made, the rates of these diagnosis groups were 35.4%, 20.1%, and 10.2%, respectively. The findings were compared with the findings of 19 previous studies published over the past 27 years. Mood, cognitive, and substance use disorders remain major foci of consultation-liaison practice in the managed care era, although the rate of cognitive disorder diagnoses has increased. No evidence was found of a change over time in referral rates.
