AIDS patients compared with others seen in psychiatric consultation.

To identify similarities and differences between AIDS patients and non-AIDS patients, all psychiatric consultations done in one year in a large voluntary general hospital were reviewed. A total of 93 consultations were done on 67 AIDS patients and 138 consultations were done on 121 comparably aged patients without AIDS. The most common AIDS risk factor was intravenous drug use. The AIDS patients were more likely to be Hispanic and male than were the non-AIDS patients. The AIDS group was also more likely to have a diagnosis of organic mental disorder, particularly dementia. There were no other differences in Axis I diagnoses, including depression, substance abuse, and adjustment disorder. Suicidal risk was no greater in the AIDS patients than in the non-AIDS patients. Axis II diagnoses were made more often in the non-AIDS patients, who also required more one-to-one nursing supervision. Consultation in AIDS patients took more staff time, and AIDS patients were more likely to have required one or more repeat consultations within the period of the study, thus creating a heavier burden on consultation staff. Although these predominantly heterosexual, Hispanic, and drug-using hospitalized AIDS patients do not show significantly higher rates of psychiatric morbidity than other, non-AIDS patients, except for more organic mental disorders, AIDS seems to create a much higher demand for psychiatric consultation services.

A profile of academic medical-psychiatric units.

Medical-psychiatric inpatient programs are a relatively recent phenomenon. Although interest in these programs seems widespread, they are still found primarily at academic medical centers. The authors surveyed 11 such academic units. Variations found between their patient populations, milieu, and organization suggest that these programs, in general, are still in an early stage of evolution. It is hoped that these data will provide a descriptive base of how these programs have developed.

Organization and development of pediatric medical-psychiatric units. Part I: Administrative, financial, and political issues.

The growing literature regarding the development of medical-psychiatric units to facilitate diagnosis and treatment of patients with combined medical and psychiatric disorders is primarily limited to adult populations. Almost no published information is available concerning combined pediatric medical-psychiatric units. This article, the first in a two-part series, outlines the organization and development of a child and adolescent medical-psychiatric unit within a pediatric hospital. Various academic, administrative, political, financial, and clinical issues that must be considered during the developmental process are delineated and discussed. The second part of the series will address clinical management issues.

A new tool for consultation-liaison funding: modified DRGs to reflect psychiatric comorbidity.

Funding for consultation-liaison (C-L) psychiatry remains an overriding obstacle to its implementation and practice. Several methods have been described to access funds for this subspecialty of psychiatry, but none has been enacted as a policy by third party payers to reimburse adequately for the service. In addition, although the consultation portion of the effort can be reimbursed in part in some cases through fee for services, the liaison portion is dependent on the donation of psychiatry time or the largesse of the host department. The efforts at Stanford to capitalize on the findings that psychiatric and medical comorbidity results in prolonged length of hospital stay and increased health resource utilization suggest that specific DRGs would be important patient groups to screen and charge for psychiatric services. Furthermore, DRGs that are accompanied by a high frequency of psychiatric comorbidity are a "target" for an additional funding aliquot to assess and manage the patient's psychiatric status.

Screening laboratory evaluation in psychiatric patients: a review.

Routine laboratory screening of psychiatric patients is a common clinical practice. Several studies have demonstrated the limited utility and higher cost of ambulatory and preadmission screening in the evaluation of general medical patients. The data concerning the use of such screening profiles in psychiatric patients are reviewed. Widespread use of extensive screening batteries, consisting of complete blood cell count (CBC), complete blood chemistry analysis, erythrocyte sedimentation rate (ESR), urinalysis, B12, folate, electroencephalogram (EEG), electrocardiogram (EKG), and chest x-ray film, is not indicated in the majority of psychiatric patients. Such investigations result in many abnormal findings, most of which are clinically insignificant and do not affect patient management and outcome. Most abnormal results can be predicted by information obtained from a careful history, review of systems, and physical examination. Certain populations appear to benefit from more extensive evaluation, including those older than 65 years of age or of low socioeconomic status, state hospital patients, patients with drug and alcohol histories, and patients with evidence of disorientation, self neglect, or organic mental disorders. The few tests that have merit as broader screening tests in asymptomatic patients include serum glucose, blood urea nitrogen (BUN), creatinine, and urinalysis. Patients on psychotropic medications should be monitored for side effects of that particular therapy. Further prospective data are needed to develop cost-efficient, population-specific diagnostic strategies.

Outpatient consultation-liaison psychiatry: a valuable addition to the training of advanced psychiatry residents.

With current health care reimbursement conditions and recent research denoting the important relationship between mental health status and poor functioning, especially in medically ill patients, one would think that consultation-liaison (C-L) psychiatry would have an increasingly viable role in the outpatient health care sector. However, only a small number of outpatient C-L clinics are reported and recently several of these have folded. These outpatient C-L clinics can follow different clinical models and have the potential, especially at the residency and fellowship training levels, for interesting and useful educational opportunities. This paper describes a recently founded outpatient C-L clinic--the Medical Illness Clinic--in a university medical center's department of Psychiatry. We highlight the structure of the clinic, the kinds of patients seen, and focus on the unique educational residency training opportunities this setting presents. The results of clinic rotation evaluations by residents are also presented. We conclude with recommendations for more exploration of this clinical model and evaluation of its utility in psychiatric residency education.

Plasma glutamate decarboxylase activity in neuropsychiatry.

Plasma glutamate decarboxylase (GAD) activity was measured in patients with endogenous psychoses and neurologic diseases. Unmedicated schizophrenic patients showed no difference in plasma GAD levels compared to controls. Administration of neuroleptics together with anticholinergic agents increased plasma GAD activity in schizophrenic patients. Compared to controls, patients with major depression and bipolar illness showed significantly lower GAD activity. No effect of antidepressants and minor tranquilizers on plasma GAD activity was found. Relatively lower GAD activity was shown in neurotic patients. The enzyme activity in plasma of patients with Huntington's chorea (HC) was lower than control levels. The plasma GAD concentrations correlated with cerebrospinal fluid concentrations in five HC patients.

Procedural validity of an abbreviated version of the SADS/RDC diagnostic process.

Formal diagnostic systems such as the Research Diagnostic Criteria (RDC) and standardized diagnostic interviews such as the Schedule for Affective Disorders and Schizophrenia (SADS) have enhanced clinical psychiatric research over the past decade. Because of the cost and time factors, however, they are not routinely used in most clinical settings. The availability of reliable alternatives compatible with clinical practice would encourage more psychiatrists to engage in clinical research. This study describes the nature and procedural validity of two such alternatives based on the RDC. Acceptably accurate, less costly research diagnostic processes can be incorporated into clinically oriented short-term acute inpatient units.

Two-tier diagnosing in psychiatry.

This article addresses the question: what is the most productive way to systematize abnormal behavior in order to study its biological roots? Though nosology still occupies the premier position in biological psychiatry, it is, in and by itself, a treacherous beacon. Syndromal organization of psychopathology is likewise seriously flawed. A functional organization of psychopathology is considered the most appropriate framework for biological research and a plea is made for a two-tier diagnostic system of psychiatric disorders. Tier one comprises the nosological diagnosis, and tier two a detailed depiction of the component psychological dysfunctions. Such a two-tier diagnostic system would bring psychopathology onto a true scientific footing.

EEG dysfunction in geropsychiatry.

Electro-clinical correlations are reported in 200 elderly patients admitted to a psychiatric ward of a general hospital. Normal EEG characteristics were generally associated with functional psychiatric disorder. Abnormal EEG features correlated with organic brain syndromes (O.B.S.). The diagnostic and pathogenetic considerations and restrictions of EEG foci, intermittent rhythmic delta activity (Irda) and diffuse EEG slowing are discussed. The informative value of EEG dysfunction in geropsychiatry is emphasised.

Theoretical tensions in biopsychosocial medicine.

Orthodoxy traditionally manages to control the potential threat from the unorthodox by a strategy of either marginalisation or incorporation. Having for so long marginalised the social sciences, biomedicine now seeks to incorporate them in a new biopsychosocial alliance. The social sciences should resist such blandishments and, rather than act in complicity with biomedicine, be free to pursue a more critical role in exposing the theoretical and empirical inconsistencies in the biomedical model.

Failure of antipsychotic drug dose to explain abnormal diurnal weight gain among 129 chronically psychotic inpatients.

1. The diurnal weight gain was found to be abnormal among 129 chronically psychotic inpatients. 2. The patients were weighed at 7 a.m. and 4 p.m. weekly for three weeks. We normalized the diurnal weight gain (NDWG) as a percentage by subtracting the 7 a.m. weight from the 4 p.m. weight, multiplying the difference by 100, and then dividing the result by the 7 a.m. weight. 3. NDWG was 2.2 +/- 1.5 percent for 87 male patients compared (p less than .0001) with .53 +/- .41 for 14 male controls. 4. NDWG was 1.8 +/- 1.0 percent for 42 female patients compared (p less than .0001) with .49 +/- .30 for 15 female controls. 5. Seventy percent of male and female patients had NDWG values greater than two standard deviations above the mean values of controls. 6. Differences in age, sex, morning weight, antipsychotic drugs, lithium, carbamazepine, phenytoin, blood pressure, and pulse did not explain these findings.

Addictive behaviors among hospitalized psychiatric patients.

A survey was conducted to assess the extent of alcohol abuse, drug abuse, obesity, and smoking among patients hospitalized on other than substance abuse treatment wards of a large psychiatric hospital. The results revealed extensive addictive behavior problems in the sample with nearly 90% of the patients having at least one of the problems. Prevalence rates for smoking and alcohol abuse substantially exceeded, and for obesity was equivalent to, the prevalence of these behaviors in the general population. Drug abuse was the least frequent problem and comparisons to the general population could not be made. Another major finding was that a relatively small proportion of patients was receiving any treatment for their addictive problems that was likely to be effective. For the most part, it seemed that patients receiving treatment were cases in which the addictive problem caused a serious immediate danger to the patient or others on the ward or seriously disrupted the ward routine.

Clinical uses of lithium salts.

A comprehensive overview of the clinical aspects of lithium therapy is presented. Emphasis is placed on recent developments regarding the clinical uses of Li2CO3 in non-psychiatric conditions. The established efficacy of the drug in the treatment and prophylaxis of mania and bipolar affective disorders is noted, and the evidence supporting the use of lithium salts as a prophylactic agent in unipolar depression, aggressive behavior, schizophrenic disorders and organic brain dysfunction is discussed. The use of lithium carbonate in various disorders of movement and in certain extrapyramidal diseases is summarized, as are the results of its trials in alcoholism and drug abuse. In addition, uses of Li2CO3 in asthma, thyroid diseases, granulocytopenia, headache, bowel disease, anesthesiology, cardiology, and sleep disorders are summarized. The data suggests the potential effectiveness of Li2CO3 in a variety of clinical conditions other than those for which it is classically indicated, provided more detailed double-blind studies are performed.

Diagnosis of organic brain syndrome: an emergency department dilemma.

Delirium and dementia frequently pose a diagnostic dilemma for clinicians in the emergency department. The overlap of symptoms between organic brain syndrome and functional psychiatric illness, coupled with a dramatic presentation, often leads to a premature psychiatric diagnosis. In this paper, the authors discuss those symptoms of organic brain syndrome that most frequently generate diagnostic confusion in the emergency department and result in a misdiagnosis of functional illness.

Differential diagnosis of psychiatric comorbidity in substance abusers.

The differential diagnosis of psychiatric comorbidity in substance abusers is important in order to provide effective pharmacological and psychotherapeutic treatments for the comorbid psychiatric disorders. Differential diagnosis of an underlying psychiatric disorder depends on the type of drug abused and the phase of abuse, ranging from acute intoxication to withdrawal. This review derives guidelines for differential diagnosis based on multiple examples of interactions between major psychiatric disorders and various abused drugs.

Nursing care hours of patients receiving varying amounts and types of consultation/liaison services.

Psychiatric comorbidities in the general hospital population have been found to increase the cost of health care. This descriptive study provides an in-depth analysis (including nursing hours), of general hospital patients receiving low, medium, and high intensity consultation/liaison (C/L) services from C/L psychiatrists and C/L nurses using computerized databases and the medical record. The results show that there are significant differences among the subgroups receiving varying amounts of C/L services. This study has particular significance for C/L nursing as many C/L nursing interventions are focused on both the patient and the delivery of nursing care by the staff nurse.
