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.

The European Consultation-Liaison Workgroup (ECLW) collaborative study ☆: I. General outline

Previous C-L psychiatric service research is seriously limited by its parochial nature; very few results can be generalized outside of the hospital in which the original study was performed because of differences in the nature of the hospital and the type of C-L service. This article presents the general outline and methodology of a European multicentered C-L service delivery study effected by the European Consultation-Liaison Workgroup for General Hospital Psychiatry and Psychosomatics (ECLW). The study is unique in its kind as it allows the comparison of very different C-L services; for example, some services are run by C-L psychiatrists, others are run by C-L psychosomaticists and the study encompasses a large variety of different settings. As a result, both common factors in C-L service delivery and specific local patterns can be explored. The overall hypothesis tested in this study was that the most developed services would see (as well as more patients) a wider variety of clinical problems than small services. The implication is that the absence of well-developed C-L services in a general hospital may mean that there are patients with unmet mental health needs. In separate articles the training and reliability testing of the new Patient Registration Form (PRF) and the Institutional and Provider characteristics will be described. The former includes the use of ICD-10 in the general hospital setting. This study is a collaborative effort made by 226 consultants from 56 psychiatric C-L services in 11 countries. Each consultant recorded details of 1 years caseload leading to a thorough description of 14,717 patients collected between 1991 and 1993. The advanced methodology included a multicentered international approach, rigid training for all participating consultants, and the development and testing of new instruments. This will allow us to assess the impact of important structural and process variables on the outcome of C-L service delivery in several European countries. These results will be reported in papers both in the international and national literature of the participating countries.

The ECLW collaborative study: III. Training and reliability of ICD-10 psychiatric diagnoses in the general hospital setting—An investigation of 220 consultants from 14 European countries

A comprehensive training program for reliable use of the ICD/10 in Consultation-Liaison (C-L) psychiatry was conducted with 220 psychiatrists and psychologists from 14 European countries. The training included rating of written test cases and development of a coding manual to avoid diagnostic pitfalls not addressed in the ICD-10 manual. Following this training, all consultants rated 13 written case histories. One hundred sixty-seven consultants (76%) had a kappa (kappa) of at least 0.70. Only 13 (6%) had a kappa 0.40. The percentage of high reliability raters was evenly distributed among the different countries. Consultants had some problems in the differentiation between adjustment disorders and depressive disorders, and in the classification of disorders where ICD-10 differs from the DSM-III-R system. National biases in diagnostic practice were found with regard to the case concept and the role of alcohol in confusional states. Finnish consultants coded no psychiatric disorder significantly more often, whereas German and Italian consultants attributed delirious state more often to alcohol than consultants from other European countries. The study demonstrates that it is possible to achieve acceptable interrater reliability in applying the ICD-10 guidelines, through training programs designed for C-L psychiatrists and psychologists. Nevertheless, this first cross-national study shows the importance of addressing differences in national diagnostic practice.

Reliable integrative assessment of health care needs in elderly persons: the INTERMED for the Elderly (IM-E).

OBJECTIVEnWith the increasing prevalence of multiple conditions in older age, the high prevalence of mental disorders, and the many social challenges facing elderly people, a high-risk patient group in need of interdisciplinary (biological, psychological, and social) care is emerging. The INTERMED interview is an integrative assessment method that identifies patients with complex health care needs. The aim of this study was to develop and evaluate the INTERMED for the Elderly (IM-E), specifically for use in populations of elderly persons.nnnMETHODSnIn focus groups conducted with the authors of the original INTERMED, the variables and anchor points that had to be adjusted to the needs and situation of the elderly and to the demands of a population-based study were discussed and altered. The final version of the IM-E was conducted with 42 elderly persons. Participants were doubly scored by two trained raters; the interrater reliability [intraclass correlation coefficient (ICC) (2,1)] was calculated.nnnRESULTSnThe IM-E was well accepted by the elderly persons interviewed. ICCs for the various domains of the IM-E ranged between .87 and .95, while the ICC for the sum score was .95. Regarding the cutoff point of 20/21 for patients with complex health care needs, a κ of .75 was achieved.nnnCONCLUSIONSnThe IM-E is a reliable integrative assessment instrument. It is well suited for epidemiological settings to adequately describe the percentage of elderly patients with complex health care needs. In clinical settings, it can be used to identify elderly patients in need of interdisciplinary care.

Patterns of comorbidity in relation to functioning (GAF) among general hospital psychiatric referrals

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.

Audit in C-L psychiatry

During the last decade medical audit has become an important tool to evaluate and modify clinical practice in both general and mental health care settings. This article reviews the role of audit in Consultation Liaison (C-L) psychiatry. Audit has played a crucial role in helping to better understand the content and the mechanisms of our own work. Scientific arguments are made to emphasize that audit, most often a form of quasi-experimental research, is a most appropriate tool for C-L psychiatric research. The current emphasis on the importance of audit is an advantage for the further development of C-L psychiatry.

P01-389 - Intermed self-assessment: developing an instrument to evaluate biopsychosocial complexity

Introduction INTERMED is a method to assess biopsychosocial case complexity and a screening instrument to identify patients with multiple care needs. It is based on an interview, brief and easy to use, that can be conducted also by a nurse. Various studies in the last 10 years have confirmed its face-validity and reliability as a clinimetric tool. Its self-assessment version (IM-SA) was developed for further implementation in clinical settings. Aim To evaluate language, structure and fluency of the IM-SA questionnaire. Methods IM-SA, Italian version 1.0, was administered to 25 patients admitted to an internal medicine ward and to other 25 in the waiting room of a Primary Care outpatient clinic. At the end of the questionnaire, nine extra-questions were specifically added to evaluate comprehension and difficulties encountered by patients while filling in the questionnaire. Results Patients admitted to the hospital scored higher and were found to be “more complex” (pxa0 Conclusion IM-SA seems to be a feasible and reliable self-assessment method to evaluate biopsychosocial complexity. Further similar studies in different languages are being organized to reach a final version of IM-SA, which will be afterwards compared to the IM professional interview.

YPSP01-05 - Intermed from training to clinical implementation: the complex patient in different care settings

Objectives INTERMED is an instrument to assess bio-psycho-social case complexity in general health care by focusing on past, present and future health needs/risks of patients. It consists of a structured interview defining 20 variables and related anchor points. The total score ranges from 0 to 60, reflecting the level of complexity and the related care needs/risks. The aim of this work was to assess preliminary the effectiveness of a training program on the clinical use of INTERMED. Methods After a group training on the use of INTERMED carried out between April and September 2009, the method was applied to 30 female patients aged between 20 and 65, subsequently referring to three clinical settings: a GP clinic; a psychiatry day-care clinic; a CLP out-patient clinic. Demographic and clinical data were collected, together with administration of HADS and WHOQoL-bref. Results The mean INTERMED score was 20.8, borderline as to definition of complex cases. Patients from the GP clinic and in the CLP setting scored lower (respectively 16.5 and 18.2) than patients from the psychiatric day-clinic (27.8), suggesting that the presence of severe psychiatric disturbances might contribute to increasing the level of case-complexity. Concordance with results at HADS and WHOQoL was high. Conclusions A clinical practice in the use of INTERMED after the theoretical phase of the training process is necessary to reinforce effectiveness of the training. These preliminary positive results will hopefully open the way to a wider diffusion of this tool in clinical practice in the area of Modena.

TRAINING ON HOW TO USE THE INTERMED : THE EXPERIENCE AT MODENA MEDICAL SCHOOL

Objectives INTERMED is an instrument to assess bio-psycho-social case complexity in general health care by focusing on past, present and future health needs and risks of patients. It consists in a structured interview defining 20 variables and related anchor points. The total score ranges from 0 to 60, reflecting the level of complexity and the related care needs/risks. The aim of this work was to describe the training process on the use of INTERMED and to assess its effectiveness. Methods A training group of 9 subjects had two-hour meetings twice a month between April and September 2009. After introductory sessions on theoretical aspects and inter-trainee simulations on interviewing and scoring techniques, students were assigned the task of producing video-recorded clinical material, which was used to comment on interviewing skills and practice on scoring. Individual and consensus scores were collected at the beginning and at the end of the training and compared statistically by means of Cohens kappa. Results Motivation and involvement of students in the training was high (participation was on a voluntary basis during extra-work hours), as satisfaction. Agreement between individual and consensus scores was high already at the beginning of the training (Cohens kappa mean value of 0.80) and slightly improved during the course. Conclusions The training process gave positive results both on the quantitative and the qualitative sides of evaluation. A six-month 25-hour training period is a reasonable time for learning how to master the instrument, although it needs to be followed by the clinical practice.
