Glucose, insulin and potassium applied as perioperative hyperinsulinaemic normoglycaemic clamp: effects on inflammatory response during coronary artery surgery.
BACKGROUND: The clinical benefits of glucose-insulin-potassium (GIK) and tight glycaemic control in patients undergoing coronary artery bypass grafting (CABG) may be partly explained by an anti-inflammatory effect. We applied GIK as a hyperinsulinaemic normoglycaemic clamp for >25 h and quantified its effect on systemic inflammation in patients undergoing CABG. METHODS: Data obtained in 21 non-diabetic patients with normal left ventricular function scheduled for elective coronary artery surgery, who were randomly allocated to a control or GIK group, were analysed. In GIK patients, regular insulin was infused at a fixed rate of 0.1 IU kg(-1) h(-1). The infusion rate of glucose (30%) was adjusted to maintain blood glucose levels within a target range of 4.0-5.5 mmol litre(-1). Plasma concentrations of interleukins 6, 8 and 10, C-reactive protein (CRP) and serum amyloid A (SAA) were measured on the day of surgery and on the first and second postoperative days (POD1 and POD2). RESULTS: In the GIK group hypoglycaemia (glucose <2.2 mmol litre(-1)) did not occur, whereas hyperglycemia (glucose >6.1 mmol litre(-1)) developed in 15% of all measurements. In control patients, hyperglycaemia developed in >80% of all measurements in the presence of low endogenous insulin levels. CRP and SAA levels increased in both groups, with maximum levels measured on POD2. GIK treatment significantly reduced CRP and SAA levels. Interleukin levels increased significantly in both groups following cardiopulmonary bypass, but no differences were found between the groups. CONCLUSION: Hyperinsulinaemic normoglycaemic clamp is an effective method of maintaining tight glycaemic control in patients undergoing CABG and it attenuates the systemic inflammatory response in these patients. This effect may partly contribute to the reported beneficial effect of glycaemic control in patients undergoing CABG.

Development and validation of a short questionnaire in community acquired pneumonia.
BACKGROUND: A short but sensitive questionnaire evaluating changes in respiratory symptoms and well being during the treatment of community acquired pneumonia (CAP) is needed. We have developed a measurement and evaluated its psychometric properties in 67 patients admitted with CAP. METHODS: The patients were asked to indicate the presence and severity of dyspnoea, coughing, coughing up sputum, coughing up sputum with ease, the colour of the sputum, fatigue, fitness, and their state of health. The item fatigue showed substantial overlap with fitness and was therefore excluded. The response of the patients to the remaining eight items was used to calculate a CAP score. RESULTS: The percentage of missing data (0.2-1.7%), floor and ceiling effects (0.2/5.5%), internal consistency (Cronbach alpha = 0.87), and the intraclass correlation coefficient for test-retest reproducibility (0.83) met predefined criteria, indicating good acceptability and reliability. Face and clinical validity were satisfactory. Effect sizes under treatment were large, indicating high responsiveness. CONCLUSION: The newly developed CAP score is a simple, reliable, valid, and highly responsive instrument. This makes it scientifically sound and clinically relevant for measuring outcome when evaluating treatment strategies in CAP.

Cyclosporin trough levels: is monitoring necessary during short-term treatment in psoriasis? A systematic review and clinical data on trough levels.
BACKGROUND: Cyclosporin is an effective treatment for severe plaque psoriasis. Unfortunately, its use may be limited by time- and dose-related nephrotoxicity. Serum trough levels may be useful for monitoring the risk of nephrotoxicity. OBJECTIVES: To determine whether monitoring of trough levels is necessary in psoriasis patients undergoing short-term treatment with cyclosporin. METHODS: A computerized and manual literature search identified studies on adults with plaque-type psoriasis treated with cyclosporin < or = 5 mg kg-1 daily, in which trough levels were measured in whole blood. Number of patients, treatment duration, formulation and dosage, renal function tests and trough levels were extracted. The association between renal function and trough levels was investigated. Additionally, in a randomized controlled trial on cyclosporin vs. methotrexate in moderate to severe psoriasis, cyclosporin trough levels were measured frequently in 20 patients during 12 weeks of treatment. The Pearson correlation coefficient between serum creatinine and cyclosporin trough levels was calculated. RESULTS: Fifty-six articles were found concerning cyclosporin trough level measurements in psoriasis patients, of which eight were analysed. Many studies were excluded due to inappropriate cyclosporin dosages used. As data were heterogeneous and lacked various key parameters, a correlation study and a meta-analysis could not be performed. Instead, a quantitative description of the literature was given. No high mean trough levels or elevations of serum creatinine were described. In our clinical study, all the mean trough levels in 17 patients treated with cyclosporin 3 mg kg-1 daily were within the therapeutic range (< 200 ng mL-1). Elevated trough levels were found in two of three patients treated with cyclosporin 3-5 mg kg-1 daily. No signs of renal dysfunction were seen. CONCLUSIONS: The literature does not provide a definitive answer on whether monitoring cyclosporin trough levels in patients with psoriasis should be standard practice. Our own data show no need for cyclosporin trough level monitoring during short-term treatment with cyclosporin 3 mg kg-1 daily. However, when cyclosporin doses are > 3 mg kg-1 daily, monitoring may be indicated.

European Consultation-Liaison Psychiatric Services: the ECLW Collaborative Study.
OBJECTIVE: To describe the patterns of organization of consultation-liaison (C-L) services in 11 European countries in relation to hospital characteristics and national approaches to C-L psychiatry. METHOD: Cross-sectional survey. RESULTS: Services can best be described in terms of their size and seniority of their staff and whether or not they are multidisciplinary. Single-discipline services are based upon the standard medical consultant model, whereas those with multidisciplinary teams work in a way that is comparable with community mental health teams. German psychosomatic C-L services belonged to either model. National differences were found. CONCLUSION: This first international study provides empirical evidence for the wide variation in the organization of C-L services. In view of the increasing numbers of patients with psychiatric disorder who are being treated in general hospitals and the changing patterns of medical care there are important implications for clarification and improvement of the role of C-L services.

[Guidelines and their observance in the psychiatric care of failed suicides in general hospitals].
OBJECTIVE: To gain insight into the guidelines established for the care of failed suicides in general hospitals, and into the degree to which these guidelines are observed in practice. DESIGN: Descriptive, retrospective. SETTING: Department of Psychiatry, Rijnstate Hospital, Arnhem, the Netherlands. METHOD: An inventory of guidelines for the care of failed suicides was made by interviewing seven psychiatrists on the staff of general hospitals. The inventory was limited to access (interval between admission and referral/consultation), and the coordination of the care (i.e. adjustment to the patient's condition, transfer of information). Subsequently, the cases of all failed suicides admitted to these hospitals in 1991 were studied to find out how these guidelines were observed in practice; use was made for this purpose of data from a more extensive European study. RESULTS: All seven hospitals proved to have rules for coping with tailed suicides. Guidelines concerning accessibility of care were fairly similar in the various hospitals; regarding the coordination of care, more local variants were found to exist. The accessibility of care was found to be mostly in accordance with the guidelines. There were more deviations from the guidelines where the coordination of care was concerned; in addition, there were substantial differences between the hospitals in the degrees to which deviation from the guidelines occurred. CONCLUSION: Guidelines for the care of failed suicides admitted to general hospitals were not in all respects similar; the observance differed markedly, especially regarding the coordination of care.

The ECLW Collaborative study II: patient registration form (PRF) instrument, training and reliability. European Consultation/Liaison Work group.
This paper describes the development and testing of the Patient Registration Form (PRF), a standardized instrument for the description of patients seen by consultation-liaison (C-L) psychiatrists and psychosomatists in general hospitals, the referral patterns, the C-L interventions and their outcomes. The PRF study is part of a large multi-centre. European investigation on the effectiveness of mental health service delivery, conducted by the European C-L Workgroup for General Hospital Psychiatry and Psychosomatics (ECLW) and performed in the framework of the of the E.C. 4th Medical and Health Research Program. The final version of the PRF consists of 68 items. It was developed by the Program Management Group (PMG) and National Coordinators (NC) after long preparatory studies to assure both face and content validity and pilot testing. Two hundred and twenty consultants, who required 40 hours of training and came from 14 different European countries and 90 different sites, participated in the final reliability study. The PRF was tested in 13 written case histories. A "gold standard' for the correct answers in each item was decided by "consensus ratings' of the PMG and a subsequent 80% agreement by the NCs. A high standard (average kappa (k) > or = 0.70; at least 2/3 of the PRF items, kappa > or = 0.70) was required for the rater to be considered as "reliable' (RR). The consultants considered the PRF both "feasible' and 93.2% of them fulfilled the RR criteria. The calculated rater-"gold standard' reliability was satisfactory: only four PRF items were identified with low agreement coefficients and no biases were observed cross-nationally in the ratings. Given the implications of misclassification for evaluating C-L effectiveness and services, these results are important and the achievement unprecedented.

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.

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.

Care complexity in the general hospital: results from a European study.
There is increasing pressure to effectively treat patients with complex care needs from the moment of admission to the general hospital. In this study, the authors developed a measurement strategy for hospital-based care complexity. The authors' four-factor model describes the interrelations between complexity indicators, highlighting differences between length of stay (LOS), objective complexity (such as medications or consultations), complexity ratings by the nurse, and complexity ratings by the doctor. Their findings illustrate limitations in the use of LOS as a sole indicator for care complexity. The authors show how objective and subjective complexity indicators can be used for early and valid detection of patients needing interdisciplinary care.

Risk factors for complex care needs in general medical inpatients: results from a European study.
The authors linked admission risk factors to a series of indicators for complex care delivery to enable detection of patients in need of care coordination at the moment of admission to the general hospital. The authors found 13 risk factors to be predictive of more than one indicator of care complexity. An admission risk screening procedure to detect patients in need of care coordination should focus on these risk factors and should include predictions made by doctors and nurses at admission and information collected from the patient and the medical chart.

COMPRI--an instrument to detect patients with complex care needs: results from a European study.
The authors developed a screening instrument to detect patients in need of complex care coordination at admission to a general hospital. On the basis of a series of risk factors for care complexity, the authors constructed a short, care complexity prediction instrument (COMPRI) and assessed its qualities. The COMPRI is an easily administered screening instrument that detects patients at risk for complex care needs for whom care coordination is indicated. COMPRI's predictive power exceeds all currently available case-mix instruments.
