Psychiatric emergency services in the Veterans Health Administration: a review.

The VA health care system is the largest source of public mental health care in the country, providing specialty mental health care services to more than 550,000 veterans annually. This chapter reviews the nature and scope of VA psychiatric emergency services.

Endoscopic placement of indigenous plastic esophageal endoprostheses--does it still have a role in the era of expandable metallic stents? A prospective Indian study in 265 consecutive patients.

BACKGROUND AND STUDY AIMS: Esophageal endoprosthesis placement is an established method of palliating inoperable esophageal malignancy. However, the prosthesis choice varies, with expandable metal stents recently gaining popularity. We present our experience of using an indigenously developed plastic prosthesis in 265 patients prospectively in the period April 1992 to May 1996. PATIENTS AND METHODS: An indigenous endoprosthesis made of a medical grade, nontoxic, radiopaque plastic material was placed successfully in 259 patients after serial dilatation of the malignant stricture. Patients were followed up once every month for at least 6 months and also in between if they developed any significant symptoms. The results were analyzed prospectively with special emphasis on the cost of the therapy, technical success of placement, improvement of swallowing and occurrence of complications. RESULTS: The technical success of placement was 97.7% (259/265 patients). The mean dysphagia score improved from 3.2 to 1.2; 212 patients (81.8%) could swallow semisolids whereas 47 patients (18.2%) could swallow liquids. Though 75 patients (28.3%) had an associated tracheoesophageal fistula and 29.8% had received prior radiotherapy/chemotherapy, immediate complications like perforation, respiratory distress or severe hemorrhage were encountered in only 4.3% of patients. Late complications occurred in 12.7% and 32.8% of the patients complained of mild post-procedure pain in the chest. The overall procedure-related mortality was 3.9%. The average cost of the prosthesis was only US$ 15 per patient. CONCLUSIONS: Placement of a plastic prosthesis is still a very effective and safe method for relief of malignancy-induced dysphagia. The associated complications can be significantly reduced by modifying the prosthesis material/design and adhering to a careful technique. The extremely low cost of the prosthesis and its safety profile makes this treatment highly cost-effective and widely applicable in developing countries such as India.

Length of inpatient stay and recidivism among patients with schizophrenia.

OBJECTIVE: The study examined whether length of hospital stay is related to recidivism among psychiatric patients. A quasi-experimental approach was used to address limitations of controlled and epidemiological research. METHODS: Three matched groups, each consisting of 55 inpatients with schizophrenia, were selected from public psychiatric units with different mean lengths of stay. Regression models were used to compare the groups on three variables: time to first readmission (survival analysis), number of readmissions (ordinal logit regression), and total time in the community in the postdischarge year (multiple linear regression). RESULTS: An analysis based on the units with different lengths of stay, which was similar to that typically used in controlled studies, found no differences in the three outcome measures. However, a second analysis that examined data for all patients irrespective of their unit assignment found that inpatients treated for 30 days or less relapsed sooner than those with stays longer than 30 days. The disparity in results was largely due to overlapping quasi-experimental conditions: many patients on the short-stay units had a long lengths of stay, and vice versa. The first analysis supports an administrative policy of short stays. The second reinforces previous findings that a group of patients, primarily young males with onset of illness at an early age and multiple previous hospitalizations, is at greater risk of relapse with short-term treatment. CONCLUSIONS: The apparent contradiction between a unit- or patient-based analysis suggests that unit-based results should be interpreted with caution when used to make clinical or utilization review decisions.

Effect of heavy alcohol intake in the absence of liver disease on bone mass in black and white men.

Previous studies have shown that bone mass is significantly decreased in chronic alcoholic white patients, especially those with evidence of liver involvement. However, liver disease is an independent risk factor for bone loss. In vitro studies have shown that alcohol has a direct effect on osteoblasts. The effects of chronic alcohol consumption on bone mass in the absence of liver disease are not known. In addition, the effect of alcohol on bone in black alcoholic subjects has not been examined previously. In the present study, we evaluated the effects of prolonged heavy alcohol intake on bone mass in both black (n = 21) and white (n = 19) male subjects without significant liver disease. Bone mineral density (BMD) of the lumbar spine and hip and various markers of bone metabolism in alcoholic subjects were compared with those in respective age-matched controls (n = 16 blacks and 14 whites). Mean values for BMD of the lumbar spine, total hip, and femoral neck were not significantly different between alcoholic subjects and their respective controls among either blacks or whites. In white subjects, age and duration of alcohol were noted to have significant independent effects on BMD, whereas in blacks, age was the only factor that significantly affected bone mass independently. In the absence of liver disease, prolonged heavy alcohol intake results in bone loss in white subjects. The skeleton of black subjects may be less affected by alcohol.

Length of stay and recidivism in schizophrenia: a study of public psychiatric hospital patients.

OBJECTIVE: Psychiatric beds in public hospitals have decreased 80% since 1955, but admissions have risen correspondingly, largely because of high recidivism rates. Decreases in numbers of beds have been partly achieved by shortening the length of stay, which lessened by half between 1970 and 1980. This study was undertaken to determine whether duration of hospital treatment affects the rate and rapidity of relapse among schizophrenic patients. METHOD: Data on 1,500 patients from 10 state hospitals were gathered for 18 months after initial discharge. Predictor variables included age, sex, marital status, race, number of previous admissions, location of the facility, and length of stay. Data were analyzed by survival analysis with a Cox regression model for two times to initial relapse: 30 days and 18 months (outcome). RESULTS: Length of stay was significantly related to each time to relapse after the effects of number of previous admissions and age were partialed out. Facility location was not predictive, but intrahospital effects were tested by examining the data on the largest facility; again, length of stay significantly predicted relapse. CONCLUSIONS: Although the magnitude of the effect was small, the clinical significance of the findings is the greater likelihood that brief-stay patients will be rehospitalized within 30 days after discharge than will patients treated for longer periods. Brief hospitalization seems generally applicable to psychiatric populations, but there may be a small but important group of seriously mentally ill patients for whom other alternatives are possibly more appropriate and should be explored.

Medical ethics in India.

Medical ethics in the Indian context is closely related to indigenous classical and folk traditions. This article traces the history of Indian conceptions of ethics and medicine, with an emphasis on the Hindu tradition. Classical Ayurvedic texts including Carakasamhita and Susrutasamhita provide foundational assumptions about the body, the self, and gunas, which provide the underpinnings for the ethical system. Karma, the notion that every action has consequences, provides a foundation for medical morality. Conception, prolongation of one's blood-line is an important ethical aim of life. Thus a wide range of practices to further conception are acceptable. Abortion is a more complex matter ethically. At the end of life death is viewed in the context of passage to another life. Death is a relief from suffering to be coped with by the thought of an eternal atman or rebirth.

Documenting the relationship between homelessness and psychiatric hospitalization.

Homelessness among mental patients is frequently associated with deinstitutionalization. In a study to clarify the relationship between homelessness and psychiatric hospitalization, data from Illinois statistical reports and from admission reports of a state hospital that serves about 75 percent of the undomiciled mentally ill population in Chicago were analyzed. The rate of homelessness had increased substantially among psychiatric admissions over the last decade and was even higher among applicants for hospitalization. The homeless had lower admission rates than the domiciled, largely because of differing paths of referral. Nearly 20 percent of the homeless left the hospital against advice, and relatively few were referred to licensed long-term-care facilities. Until various systems develop adequate responses to the problem, both the numbers and the visibility of the homeless mentally ill are likely to increase.
