Detection and Treatment of Mental Disorders in General Health Care

Mental health service delivery in the general health care sector is restricted with regard to understanding the magnitude and impact of mental illness in the medically ill (co-morbidity), as well as the significance of current mental health service delivery. A new model in development in the framework of a Biomed2 grant is presented. It consists of case-finding through complexity of hospital care prediction (COMPRI) followed by an integral health service needs assessment (INTERMED). It might serve to develop a more structural relation with the general health care sector for the management of mentally co-morbid high utilizing patients.

Suicidality in Women with Adjustment Disorder and Depressive Episodes Attending an Irish Perinatal Mental Health Service

Depression is common in the perinatal period, with prevalence rates of 14.4%, but prevalence rates of adjustment disorder in this period have not been established. We aimed to examine the characteristics of women attending a perinatal psychiatry service diagnosed with adjustment disorder (AD) or depressive episodes (DE). The data were collected as part of a multicentre case-control study of 370 patients, 45 of whom were recruited from perinatal psychiatry service at a maternity hospital. We recruited 45 patients with AD or DE diagnosed in the perinatal period and compared them to a matched sample of 109 non-perinatal women. Almost half, 22 (48.9%) perinatal women had a diagnosis of AD and 23 (51.1%) had a diagnosis of DE. Of the perinatal participants, those with AD had more stressful life events, and suicidal ideation and behaviours were three times more common (31.8%) in AD than in DE (8.7%). There were no significant differences in levels of suicidality between the perinatal and the non-perinatal groups. In our cohort, AD is associated with symptoms of depression including suicidal ideation during the perinatal period. Further study is required to examine the relationship between stressors and suicidality in this population.

Delirium diagnosis defined by cluster analysis of symptoms versus diagnosis by DSM and ICD criteria: diagnostic accuracy study

BACKGROUND

Information on validity and reliability of delirium criteria is necessary for clinicians, researchers, and further developments of DSM or ICD. We compare four DSM and ICD delirium diagnostic criteria versions, which were developed by consensus of experts, with a phenomenology-based natural diagnosis delineated using cluster analysis of delirium features in a sample with a high prevalence of dementia. We also measured inter-rater reliability of each system when applied by two evaluators from distinct disciplines.

METHODS

Cross-sectional analysis of 200 consecutive patients admitted to a skilled nursing facility, independently assessed within 24-48 h after admission with the Delirium Rating Scale-Revised-98 (DRS-R98) and for DSM-III-R, DSM-IV, DSM-5, and ICD-10 criteria for delirium. Cluster analysis (CA) delineated natural delirium and nondelirium reference groups using DRS-R98 items and then diagnostic systems' performance were evaluated against the CA-defined groups using logistic regression and crosstabs for discriminant analysis (sensitivity, specificity, percentage of subjects correctly classified by each diagnostic system and their individual criteria, and performance for each system when excluding each individual criterion are reported). Kappa Index (K) was used to report inter-rater reliability for delirium diagnostic systems and their individual criteria.

RESULTS

117 (58.5 %) patients had preexisting dementia according to the Informant Questionnaire on Cognitive Decline in the Elderly. CA delineated 49 delirium subjects and 151 nondelirium. Against these CA groups, delirium diagnosis accuracy was highest using DSM-III-R (87.5 %) followed closely by DSM-IV (86.0 %), ICD-10 (85.5 %) and DSM-5 (84.5 %). ICD-10 had the highest specificity (96.0 %) but lowest sensitivity (53.1 %). DSM-III-R had the best sensitivity (81.6 %) and the best sensitivity-specificity balance. DSM-5 had the highest inter-rater reliability (K =0.73) while DSM-III-R criteria were the least reliable.

CONCLUSIONS

Using our CA-defined, phenomenologically-based delirium designations as the reference standard, we found performance discordance among four diagnostic systems when tested in subjects where comorbid dementia was prevalent. The most complex diagnostic systems have higher accuracy and the newer DSM-5 have higher reliability. Our novel phenomenological approach to designing a delirium reference standard may be preferred to guide revisions of diagnostic systems in the future.

Distinguishing between adjustment disorder and depressive episode in clinical practice: the role of personality disorder

BACKGROUND

There is significant symptomatic overlap between diagnostic criteria for adjustment disorder and depressive episode, commonly leading to diagnostic difficulty. Our aim was to clarify the role of personality in making this distinction.

METHODS

We performed detailed assessments of features of personality disorder, depressive symptoms, social function, social support, life-threatening experiences and diagnosis in individuals with clinical diagnoses of adjustment disorder (n=173) or depressive episode (n=175) presenting at consultation-liaison psychiatry services across 3 sites in Dublin, Ireland.

RESULTS

Fifty six per cent of participants with adjustment disorder had likely personality disorder compared with 65% of participants with depressive episode. Compared to participants with depressive episode, those with adjustment disorder had fewer depressive symptoms; fewer problems with social contacts or stress with spare time; and more life events. On multi-variable testing, a clinical diagnosis of adjustment disorder (as opposed to depressive episode) was associated with lower scores for personality disorder and depressive symptoms, and higher scores for life-threatening experiences.

LIMITATIONS

We used clinical diagnosis as the main diagnostic classification and generalisability may be limited to consultation-liaison psychiatry settings.

CONCLUSIONS

Despite a substantial rate of likely personality disorder in adjustment disorder, the rate was even higher in depressive episode. Moreover, features of likely personality disorder are more strongly associated with depressive episode than adjustment disorder, even when other distinguishing features (severity of depressive symptoms, life-threatening experiences) are taken into account.

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.

A diagnostic interview for acute stress disorder for children and adolescents

The goal of this study was to develop a semistructured clinical interview for assessing acute stress disorder (ASD) in youth and test its psychometric properties. Youth (N = 168) with an acute burn or injury were administered the acute stress disorder module of the Diagnostic Interview for Children and Adolescents (DICA-ASD). The DICA-ASD demonstrated strong psychometric properties, including high internal consistency (alpha = .97) and perfect diagnostic interrater agreement (kappa = 1.00). Participants diagnosed with ASD scored significantly higher than those not diagnosed on validated traumatic stress symptomatology measures but not on other symptomatology measures, providing evidence of convergent and discriminant validity. Preliminary evidence supports the reliability and validity of the first semistructured clinical interview for diagnosing ASD in youth.

Affective syndromes and their screening in cancer patients with early and stable disease: Italian ICD-10 data and performance of the Distress Thermometer from the Southern European Psycho-Oncology Study (SEPOS)

BACKGROUND

The assessment of mood and anxiety disorders secondary to cancer by using easy-to-administer instruments has been the object of recent research.

METHODS

The aim of this study was to examine the accuracy of the short screening tool developed by the National Comprehensive Cancer Network Clinical Practice Guidelines for Distress Management, (0-10 point-scale Distress Thermometer) (DT) in detecting affective syndrome disorders in Italian cancer patients. The sample consisted of 109 cancer outpatients who were administered the ICD-10 psychiatric interview (CIDI), the DT and the Hospital Anxiety Depression Scale (HADS).

RESULTS

Forty-four patients (40.4%) met the criteria for an ICD-10 diagnosis of affective syndromes. The DT was significantly associated with HADS-Total score (r=0.66, p=0.001). A cut-off > or = 4 on the DT showed a sensitivity of 79.5% and a specificity of 75.4% (positive predictive value--PPV = 68.6%; negative predictive value--NPV = 84.5%). The cut-off score > or = 10 on the HADS was associated with a sensitivity of 86% and a specificity of 81.5% (PPV = 76%; NPV = 89.9%). A cut-off score > or = 5 on DT and > or = 15 on HADS maximized sensitivity (78.6% and 85%, respectively) and specificity (83.1% and 96%, respectively) for patients with more severe affective syndromes (major depression, persistent depressive disorders).

CONCLUSIONS

The results suggest that simple instruments can be used as feasible tools in the screening of mood and anxiety disorders among cancer patients.

Three model curricula for teaching clinicians to use the ICF

PURPOSE

Three systematic programmes to train health professionals to use the World Health Organization's International Classification of Functioning, Disability, and Health (ICF) are described, along with efforts to evaluate their effectiveness.

METHODS

The first programme was a randomized study comparing the effects of a 2-hour instructor-led programme and a self-directed learning module on ICF-related knowledge, attitudes, and coding skills among occupational therapy graduate students. The second programme was a series of intensive 3.5-day workshops for public sector rehabilitation professionals in South Africa. The third programme involved a series of internet-based teaching modules regarding the ICF for graduate students in rehabilitation counselling.

RESULTS

The first project found that both instructor-led and self-guided training formats were effective in improving basic ICF-related knowledge, but only instructor-led training led to a significant improvement in coding skill. It also had more positive effects on ICF-related attitudes. This approach to learning assessment was generalizable to multidisciplinary health professionals in South Africa, who achieved a relatively high degree of coding accuracy after the 3.5-day workshop. Participant evaluations supported the structure, content, and length of the training. Students in the third programme also reported a very positive learning experience and positive views of the ICF.

CONCLUSIONS

An empirical basis is important for identifying the best and most efficient training methods for particular audiences and specific purposes. The length and format of training can be differentially related to specific training goals (i.e., knowledge, attitudes, and coding skills). Interactive distance learning methods may help to overcome the weaknesses of self-directed training in comparison to face-to-face training.

Correcting biases in psychiatric diagnostic practice in Northwest Russia: comparing the impact of a general educational program and a specific diagnostic training program

BACKGROUND

A general education in psychiatry does not necessary lead to good diagnostic skills. Specific training programs in diagnostic coding are established to facilitate implementation of ICD-10 coding practices. However, studies comparing the impact of these two different educational approaches on diagnostic skills are lacking. The aim of the current study was to find out if a specific training program in diagnostic coding improves the diagnostic skills better than a general education program, and if a national bias in diagnostic patterns can be minimised by a specific training in diagnostic coding.

METHODS

A pre post design study with two groups was carried in the county of Archangelsk, Russia. The control group (39 psychiatrists) took the required course (general educational program), while the intervention group (45 psychiatrists) were given a specific training in diagnostic coding. Their diagnostic skills before and after education were assessed using 12 written case-vignettes selected from the entire spectrum of psychiatric disorders.

RESULTS

There was a significant improvement in diagnostic skills in both the intervention group and the control group. However, the intervention group improved significantly more than did the control group. The national bias was partly corrected in the intervention group but not to the same degree in the control group. When analyzing both groups together, among the background factors only the current working place impacted the outcome of the intervention.

CONCLUSION

Establishing an internationally accepted diagnosis seems to be a special skill that requires specific training and needs to be an explicit part of the professional educational activities of psychiatrists. It does not appear that that skill is honed without specific training. The issue of national diagnostic biases should be taken into account in comparative cross-cultural studies of almost any character. The mechanisms of such biases are complex and need further consideration in future research. Future research should also address the question as to whether the observed improvement in diagnostic skills after specific training actually leads to changes in routine diagnostic practice.

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.

The effect of gender in diagnosing early schizophrenia--an experimental case simulation study

BACKGROUND

Studies of diagnostic practice confirm that there is a diagnostic delay in diagnosing women with schizophrenia compared to diagnosing men. The aim of the present study was to investigate the diagnostic practice of Norwegian and Russian psychiatrists when it comes to early psychosis, emphasising gender differences. We wanted to study the association between patient gender as such and diagnostic decision-making among psychiatrists.

MATERIALS AND METHODS

Psychiatrists in Norway and the Archangels region in Russia were invited to participate in a study of diagnostic practice, and received a written case description of a patient with early psychosis symptoms that could be interpreted as schizophrenia. They were, however, not informed that 50% of them received a female case description and 50% a male case description. Apart from the patient being described as "he" or "she" the stories were identical. Effects of patient gender, clinician gender, age and main area of interest were estimated using logistic regression analysis.

RESULTS

A total of 467 psychiatrists answered the questionnaire. We found that schizophrenia diagnosis was given significantly more often to the male case than to the female case. Our finding remained significant after adjustment for country, clinician gender, age and main area of interest, and is unlikely to be explained by known biases.

CONCLUSION

Patient gender in itself affects clinicians' diagnostic practice regarding schizophrenia, as schizophrenia diagnosis is given significantly more often to a male case description than to a female one, the descriptions being otherwise identical.

Psychosomatischer Liaisondienst am Universitätsklinikum

BACKGROUND

Little is known about the complex decision-making process involving recognition of psychosocial stress, its diagnosis, and psychotherapeutic intervention within the framework of a psychosomatic consulting and liaison service.

PATIENTS AND METHODS

Psychosocial stress was recorded using a psychometric questionnaire for 392 patients on admission to hospital, the estimated need of psychotherapeutic treatment, and the application of a psychosomatic liaison service.

RESULTS

Of the examined patients, 44% presented with at least one mental disorder requiring treatment according to ICD-10 criteria. According to the expert opinions, a need for psychotherapeutic treatment was present in 41%, while 54% were themselves motivated for at least one of the psychotherapeutic treatments offered. Psychotherapy was actually received by 35% of the patients. While mental disorders and emotional distress were significant predictors of the need for treatment as rated by experts, they played no genuine role in determining indication or whether a patient accepts the use of psychotherapy

CONCLUSION

Psychotherapeutic interventions in the liaison service are not always effective or related to the indication.

A comparative study of diagnostic practice in psychiatry in Northern Norway and Northwest Russia

BACKGROUND

The co-operation between psychiatrists in Norway and Russia is increasing. The object of this study was to find out whether there were differences in diagnostic practice of psychiatrists in both countries, to look at the nature of the differences and to examine whether these differences affected diagnostic quality.

METHOD

Thirty medical doctors working at psychiatric hospitals in both countries diagnosed 12 clinical case vignettes selected from a wide spectre of psychiatric disorders.

RESULTS

The Russian clinicians used a larger range of diagnoses than the Norwegians. The Russians tended to diagnose schizophrenia and schizophrenia-like disorders in cases that presented psychotic syndromes, and somatoform disorders in cases that presented agoraphobia. The Norwegians tended to evaluate affective aspects in preference to psychotic symptoms in the case of schizoaffective disorder and overestimate the degree of depression. In general, the Russians had lower total score of correct answers than the Norwegians.

CONCLUSION

In spite of the limitations due to minor differences in the data collection phase in the two countries, the study clearly demonstrates differences in diagnostic practice between the countries.

Interrater Reliability, Prevalence, and Relation to ICD-10 Diagnoses of the Diagnostic Criteria for Psychosomatic Research in Consultation-Liaison Psychiatry Patients

The Diagnostic Criteria for Psychosomatic Research (DCPR) have been proposed by an international group of psychosomatic investigators as an operationalized tool for the assessment of psychological distress in medical patients. The aims of the present study were to evaluate interrater reliability, the distribution of DCPR syndromes, and their relationship with ICD-10 diagnostic categories. One hundred consecutive patients who were referred for psychiatric consultation in a university general hospital consented to assessment for DCPR syndromes as elicited in a joint interview conducted by two researchers. The results showed excellent interrater agreement, with kappa values for the 11 DCPR syndromes ranging from 0.69 to 0.97. More patients met criteria for one or more of the DCPR (87%) than for an ICD-10 diagnosis (75%). Four DCPR syndromes were particularly prevalent: demoralization, alexithymia, illness denial, and type A behavior. DCPR criteria appear to be a useful, reliable, and promising approach in the assessment and description of psychological distress in medical patients. They may serve as a focus of intervention studies in this population.

Psychosocial distress and need for psychotherapeutic treatment in cancer patients undergoing radiotherapy

BACKGROUND AND PURPOSE

Empirical investigations examining the need for psychotherapeutic treatment of inpatients in radio-oncology departments are rare. We, therefore, assessed the degree of psychosocial distress of radio-oncology inpatients and their need for psychotherapeutic interventions.

PATIENTS AND METHODS

Eighty-seven patients from two radio-oncology wards underwent psychodiagnostic interviews and completed self-rating instruments to determine mental disorders, psychosocial distress, coping strategies and quality of life. Need for psychotherapeutic interventions and treatment motivation were estimated by patients and by a professional.

RESULTS

Using ICD-10 criteria, mental and behavioral disorders were diagnosed in 51% of the patients, most of them adjustment disorders. The professional regarded 32.2% of patients as needing psychotherapeutic treatment, compared with 43% of the patients who were motivated to accept at least one of the psychotherapeutic treatments offered. There was a marked discrepancy between the points of view of the patient and the professional, in that, while the professional regarded anxiety as a highly significant predictor of the need for treatment, psychosocial distress played no role in the patients' estimation.

CONCLUSIONS

In determining the indication for psychotherapeutic treatment, both objectified psychosocial distress and a patients' subjective treatment expectations should be considered. There is a need to develop screening instruments that integrate both aspects.

The modena consultation-liaison psychiatry service, Italy

The Reform Law 180, approved in Italy in 1978, had – and still has – great national and international significance for its dramatic consequences on both clinical and health organisational aspects of psychiatry: the law, in short, had the great effect of bringing psychiatry back to medicine, to the community and to the general hospital. This was the starting point of other relevant events, one of which was the establishment of the specialty of consultation-liaison psychiatry in Italy (Cazzulloet al, 1984). Since then, consultation-liaison psychiatry has gradually developed worldwide and in Italy as a super-specialised branch of psychiatry, able to put into practice – to operationalise – the great psychosomatic tradition in its three interrelated strands of clinical, teaching and research activities. The report that follows is strongly influenced by this historical background.

Psychosomatic liaison service in hematological oncology: need for psychotherapeutic interventions and their realization

Empirical investigations examining the psychosocial distress and need for care of inpatients with hematological malignancies are rare. Little is known about the use of psychotherapeutic interventions in routine care. To evaluate the psychosocial distress of hemato-oncological inpatients, the need for psychotherapeutic interventions and their realization in the framework of a psychosomatic liaison service has been assessed. Seventy-two patients from two hematological oncology wards underwent psychodiagnostic interviews and completed self-rating instruments, elucidating mental disorders, psychosocial distress, coping strategies, quality of life, treatment motivation and psychotherapeutic interventions. Using ICD-10 criteria, mental and behavioural disorders were diagnosed in 53% of patients. Professional assessment indicated a need for psychotherapeutic treatment in 49%, while 38% of the patients wished to receive psychological support. Actual intervention occurred for all patients in the bone marrow transplantation unit and for 23% of patients in the general hemato-oncological ward. There is considerable need for psychotherapeutic treatment which can only be handled within the framework of a liaison service in close cooperation with oncologists, nurses and mental health specialists.

Consultation-liaison psychiatry in obstetrics and gynecology

Data documenting the activity of Modena and Reggio Emilia University Hospital Consultation-Liaison Psychiatry Psychosomatic Service (C-LPPS) to the 59 bed gynecological-obstetric unit are compared to the corresponding European Consultation Liaison Workgroup (ECLW) study results and discussed in the light of recent epidemiological studies suggesting a low rate of detection and psychiatric referral in obstetric and gynecological patients. All psychiatric consultations of gynecological-obstetric inpatients during a 3-year (1996-1998) period were included in this study and data were derived from valid and reliable consultation forms tested for reliability. Within the 3-year period 55 patients were referred to C-LPPS by the gynecological-obstetric unit for psychiatric consultation. Referral rate was 0.5% of the admitted patients in the unit. The gynecological-obstetric group represented 2.5% (vs. 4.5% ECLW study) of all psychiatric consultations requested in the study period. The most frequent reasons for referral were: current psychiatric symptoms (47.3% Modena study vs. 39% ECLW), psychiatric history (20% vs. 7.3%), unexplained physical symptoms (12.7% vs. 16.2%) and coping-compliance problems (3.6% vs. 16.6%). The most common ICD-10 psychiatric diagnoses were: neurotic, anxiety and adjustment disorders (41.8% vs. 31.2%), mood disorders (29% vs. 18.4%), personality disorders (7.3% vs. 6.1%), schizophrenic and other psychotic disorders (5.5% vs. 7%).

Referrals to a liaison psychiatry out-patient clinic in a UK general hospital: a report on 900 cases

OBJECTIVE

To describe the demographic and clinical characteristics of consecutive referrals to an out-patient liaison psychiatry clinic in a large university hospital in the UK.

METHOD

We studied 900 patients using a standardized proforma. Assessments of functional capacity were made using the Global Assessment of Functioning (GAF) scale, and each patient was assigned a psychiatric diagnosis using ICD-10 criteria.

RESULTS

Four of five of all referrals presented with somatic complaints, and 41% had a concurrent physical illness. The most common psychiatric diagnoses were somatoform disorders (55%) and neurasthenia (11%). Although more than half (59%) had no previous psychiatric history, a surprisingly high number (35%) had significant functional impairment (scores of < 50 on the GAF scale). The lack of adequate psychological treatment services often provided a barrier to optimal management of some of the more disabled patients.

CONCLUSION

The general hospital liaison psychiatry clinic provides an acceptable setting in which to assess and manage patients referred from non-psychiatric colleagues.

Implementation of a psychiatric consultation service: a single-site observational study over a 1-year-period

This study describes changes in consultation process variables and referral patterns after implementation of a psychiatric consultation service at a university hospital in Germany. Two hundred eighty consecutive medical-surgical inpatient referrals for psychiatric consultation during a 1-year period were documented prospectively with a structured database. Changes took place in referral patterns and in psychiatric interventions and recommendations but not in psychiatric diagnoses. In addition, information is given on psychiatric and psychosomatic consultation service delivery in Germany.

Referral pattern of neurological patients to psychiatric Consultation-Liaison Services in 33 European hospitals

The referral pattern of neurological patients to 33 European psychiatric consultation-liaison (C-L) services in the general hospital was examined. Analyses were conducted on the ECLW CS data set, which consists of 14,717 psychiatric C-L referrals made in 56 European hospitals during 1991. Psychiatric referrals of patients admitted to neurological wards were compared to referrals from other wards. Information was obtained from 33 neurological wards, consisting of 34,506 neurological admissions. Of these admissions, 839 were referred to C-L psychiatry. The median consult rate among the hospitals was 1.8%. Compared to other hospital wards, patients referred from neurology were more frequently diagnosed as suffering from somatoform (P<.01) and dissociative disorders (P<.01), and less from substance abuse (P<.01) and delirium (P<.01). Referral to C-L psychiatry from neurological wards is characterized by an underestimation of psychiatric co-morbidity and a late detection, comparable to other medical specialties. An appeal is made for a standardized referral procedure including admission screening method, detecting patients at risk for nonstandard care during their hospital admission.

Consultation-Liaison psychiatric service delivery: results from a European study

The reported findings of the European Consultation-Liaison Workgroup (ECLW) Collaborative Study describe consultation-liaison service delivery by 56 services from 11 European countries aggregated on a C-L service level. During the period of 1 year (1991), the participants applied a standardized, reliability tested method of patient data collection, and data were collected describing pertinent characteristics of the hospital, the C-L service, and the participating consultants. The consultation rate of 1% (median; 1.4% mean) underscores the discrepancy between epidemiology and the services delivered. The core function of C-L services in general hospitals is a quick, comprehensive emergency psychiatric function. Reasons to see patients were the following. deliberate self-harm (17%), substance abuse (7.2%), current psychiatric symptoms (38.6%), and unexplained physical complaints (18.6%) (all means). A significant number of patients are old and seriously ill. Mood disorders and organic mental disorders are most predominant (17.7%). Somatoform and dissociative disorders together constitute 7.5%. C-L services in European countries are mainly emergency psychiatric services and perform an important bridge function between primary, general health, and mental health care.

Older patients referred to a consultation-liaison psychiatry clinic

BACKGROUND

Little is known about the psychiatric disorders which are associated with somatic presentations of psychological distress in older people.

METHOD

A study of patients aged 65 years and over referred to an adult consultation-liaison psychiatry clinic in a general hospital.

RESULTS

Of 900 patients referred over a 7-year period, 45 (5%) were aged 65 years and over. The most frequent ICD-10 diagnostic category was somatoform disorder (N=30) followed by depressive disorder (N=6). The age of onset of the physical symptoms was significantly earlier in those with somatoform disorders (mean 49 years; SD 3.1 years) compared with patients with depressive disorders (mean 74 years; SD 3.1 years) (p<0.05). All diagnoses were equally associated with moderate functional impairment.

CONCLUSION

Medically unexplained physical symptoms may occur as part of a range of psychiatric disorders in older people and diagnostic groups are distinct in a number of ways. The usefulness of the ICD-10 classification of disorders in relation to these patients is considered. Implications for the delivery of old age psychiatry services are discussed.

European consultation-liaison services and their user populations: the European Consultation-Liaison Workgroup Collaborative Study

The authors identified variations in the characteristics of patients referred to 56 consultation-liaison (C-L) services in 11 European countries. The authors found differences in the types of patients referred to the services, and there were significant differences between countries. The first difference lays in whether services saw patients for deliberate self-harm and for substance abuse. German psychosomatic C-L services saw virtually no such patients, although in other C-L services these patients constituted one-quarter to one-third of the patients referred. The second difference lays in the remaining group of referred patients. This group is best characterized by two dimensions. One describes the severity of psychopathology -- ranging from organic mental conditions to somatization. The other describes the clarity of the physical diagnosis -- ranging from patients referred by surgical wards to those referred by general medicine and neurology wards.

The development of clinical indicators for a consultation-liaison service

OBJECTIVE

The aim of this paper is to describe the development and implementation of clinical indicators in the consultation-liaison service at Royal Melbourne Hospital (RMH).

METHOD

A working party lead by the University of Melbourne was established in 1998 to develop clinical indicators and a database for the RMH consultation-liaison service. Core parameters for measuring service functioning and six clinical indicators were developed. The system was implemented using a data collection form and computerised database operating within a system of regular clinical reviews.

RESULTS

The clinical indicators, database and review system were found to be a feasible, useful and efficient addition to a consultation-liaison service at a major general hospital.

CONCLUSIONS

Clinical indicators may be used within specialist psychiatry services to enhance clinical care and aid in service development and teaching.

Psychosocial problems secondary to cancer: an Italian multicentre survey of consultation-liaison psychiatry in oncology. Italian Consultation-Liaison Group

Data relative to consultation-liaison psychiatry (C-L) in oncology are lacking. In order to examine this area, a multicentre investigation was conducted in 17 general hospitals in Italy. All psychiatric consultation requests for cancer patients referred to C-L during a 1-year period were evaluated. Only 5% (n=217 referred patients: 114 men and 103 women) of all C-L activity were for cancer patients. Most were 'routine' consultations (72%) for current psychiatric symptoms (69%) or coping/compliance problems (12%). Previous psychological or psychiatric disorders were shown in 32% of cases. Approximately 40% of patients were not informed of their referral to C-L. The most frequent ICD-10 psychiatric diagnoses were adjustment disorders (27%) and major affective disorders (23%). Transfer to psychiatric units was low (1%). These findings indicate the need for improvement of referral criteria to C-L and closer attention to continuity of psychosocial care of cancer patients during hospitalisation and post-discharge.

A multicenter investigation of consultation-liaison psychiatry in Italy. Italian C-L Group

In order to evaluate the extent and quality of consultation-liaison (C-L) activity in Italy, a multicenter investigation was conducted in 17 general hospitals. All of the hospitalized patients referred to C-L psychiatry during a 1-year period were assessed by means of a specific instrument (Patient Registration Form, PRF-SF). Of 518,212 patients, 4182 were referred to C-L services (referral rate = 0.72%). Typical consultations were for female patients (60.1%), admitted to medical wards (71.5%), aged 55-75 years. Most interventions were carried out within 2 days; a minority (22%) were urgent requests. Gastrointestinal and cardiovascular disorders, and unexplained medical symptoms were the most frequent ICD-9 somatic diagnoses at admission. One-third of the patients were not informed of having been referred to C-L and half of them had a lifetime history of psychiatric disturbances. Most frequent ICD-10 psychiatric diagnoses were neurotic, stress-related, and somatoform syndromes (33.1%), affective syndromes (19.4%), and organic mental syndromes (10.7%). Two-thirds of the patients were given only one consultation whereas the reminder received two to four follow-up visits. The rate of transfer to psychiatric wards was low (2.1%). Psychopharmacological treatment was suggested in 65% of cases, and 75.5% of the patients were referred to community psychiatric care at discharge. The implications of the findings are discussed.

Patterns of comorbidity in relation to functioning (GAF) among general hospital psychiatric referrals. European Consultation-Liaison Workgroup

Improvement of services for physically ill patients with concurrent psychiatric problems is a noteworthy issue in general hospitals. Among 1249 general hospital in-patients referred for psychiatric consultation, concurrent mental and behavioural disorders (ICD-10) were diagnosed in 84% of cases. Any concurrent mental and behavioural disorder was associated with dramatically low functioning (GAF = 46), indicating serious psychosocial impairment. This is a striking new finding of clinical importance. The effect on functioning was similar for substance use disorders, other mental disorders, and combined mental and substance use disorders (dual diagnoses), with no gender differences. This finding highlights the need for specialized interventions among general hospital in-patients referred for psychiatric consultation.

Factors predictive of referral to psychiatric hospital among general hospital psychiatric consultations

The aim of this paper was to explore the factors necessitating psychiatric hospital care in a Finnish multi-centre study of general hospital in-patients referred for psychiatric consultation. The study group consisted of 1251 patients referred to psychiatric hospital (n = 181) and a comparison group (n = 1070) consisting of subjects who were not referred. Differences between groups were studied by univariate analysis. Logistic regression analysis was used both to assess the factors contributing to referral to psychiatric hospital and to create predictive models. The validity of the models was analysed by means of receiver operating characteristic (ROC) curves in an independent sample. Psychiatric hospital care during the previous 5 years was associated with a 3.7-fold (odds ratio) increased risk of hospitalization. A diagnosis of psychosis was associated with a 2.9-fold increased risk, and attempted suicide as a reason for consultation was associated with a 2.1-fold increased risk. Not being married doubled the risk, and the odds ratio was also high in cases of poor psychosocial functioning (as assessed by Global Assessment of Functioning (GAF) score). The predictive model differentiated reasonably well between those patients who were hospitalized and the other patients. In conclusion, this multi-centre study of factors predictive of referral to psychiatric hospital among general hospital patients revealed that the most important determinants were previous psychiatric care, diagnosis of psychosis or severe depression, attempted suicide, being unmarried, and poor psychosocial functioning as assessed by GAF score.

The contribution of epidemiology to psychosomatic medicine

OBJECTIVE

To discuss the contribution of epidemiology and epidemiological methods to psychosomatic medicine.

METHOD

Critical review of the literature, including both philosophical concepts and empirical data.

RESULTS

The adjective "psychosomatic" has been used in two different ways: in the so called "psychosomatic" or holistic approach to medicine; and in a narrower approach, referring to particular disorders in which psychological factors were considered to have a fundamental aetiological role. While the ideal of the holistic, "humanistic" or "anthropological" approach should probably be never abandoned, the practical limitations of encompassing models, including Engel's bio-psycho-social model are also obvious: they may be heuristically sterile. On the other side, in relation to the narrow psychosomatic approach, psychogenetic views in the so called "psychosomatic illnesses" have been strongly criticized on empirical grounds. The potential of epidemiological methods to study these illnesses, but also "somatopsychic" disorders is shown in a number of papers in the empirical literature. We have grouped such contributions, including our own experience, in the five categories suggested by M. Shephered for epidemiological methods in general: 1) the completion of the spectrum of disease; 2) the establishment of outcome; 3) the actuarial assessment of morbid risk; 4) the evaluation of the efficacy of treatment; and 5) the conceptual construction of diagnosis and classification.

CONCLUSIONS

The contribution of epidemiological data to areas of interest in psychosomatic medicine has been relevant in recent years. The potential of epidemiological methods in this area is very important both to increase knowledge and to improve the quality of clinical practice.
