The present study replicates that of De Freitas and Schwartz (1979), using more typical chronic patients (on open wards rather than locked wards), and monitoring coffee intake with serum caffeine levels. The serum caffeine levels observed indicate that caffeine can be effectively manipulated on an open ward by switching the type of coffee served. Contrary to our predictions, no significant improvements in patients' behavior occurred when decaffeinated coffee was first introduced, nor was there any deterioration when regular coffee was reinstated. Only after decaffeinated coffee was introduced for the second time did any of the predicted changes occur; however, the improvements were few in number and may be accounted for by the considerable effect of time per se across all time periods. Although the findings cannot be generalized to all psychiatric patients, the results do not support recent calls for a switch to decaffeinated coffee for this population of inpatients (i.e., chronic schizophrenic patients on high doses of neuroleptics who drink large amounts of coffee).
This study was designed to identify the variables that influence a review panel's decision to discharge or detain an involuntary patient. A group of fifty patients consecutively discharged by the review panel of a provincial mental hospital were compared according to thirty-five variables, with a group of forty-five patients consecutively detained by the panel. The variable set included information on the patient's psychiatric history, current hospitalization and treatment as well as ratings of dangerousness, insight and psychopathology, as reflected in the attending physician's case summary prepared for the review panel. The released and detained groups were found to be remarkably similar. They differed on ten of the thirty-five variables measured, but they did not differ on some variables that one would expect to form the basis of the panel's decision, including diagnosis and a history of suicide attempts. On the other hand, when the predictive value of the variable set as a whole was examined using discriminant analysis, the results indicated that there was a substantial amount of predictability to the review panel process. The group membership of 77.5% of the patients can be predicted from only nine variables that contribute to the discriminant function. The results will be of interest to clinicians who deal with review panels on a regular basis and the findings have implications for other practical issues including discharge planning and readiness for community living.
The authors describe intoxicationrelated behavior patterns observed among 89 chronic schizophrenic inpatients over a 5-year period. These include caffeine intoxication, water intoxication, antihistamine intoxication, nicotine withdrawal, voluntary hypei'venUlation, and ingestion of deodorants and aerosols. Affected patients tended to abuse multiple substances in the hospital, to have generalized polydipsia, and to have histories of drug or alcohol abuse before hospitalization. Periodic intoxication in this population may be an important contributor to the refractoriness of their psychotic symptoms.
This paper critically examines the code of ethics that applies to practising psychiatrists. The code performs the functions for which it was designed admirably well. It does not, however, resolve moral dilemmas (i.e., complex situations in which any course of action compromises certain ethical principles). In these cases, the psychiatrist must turn to wider moral theory (i.e., psychiatric ethics) for guidance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
