Discharge of the asthmatic patient.

Asthma continues to be a challenging disease to treat in both the inpatient and outpatient settings. The growing database on therapeutic interventions at the time of transition from the acute to chronic phase of this disease is encouraging. Glucocorticoids and inhaled beta-agonists clearly reduce readmission and relapse. Other medications and educational interventions also appear effective. Still, no true discharge guidelines have been established. Multiple statements by consensus panels have recommended using FEV1 or PEFR as indicators of readiness for discharge, but this has not been prospectively validated from either the emergency department or inpatient setting. In contrast, some studies argue that pulmonary functions do not accurately predict relapse and readmission, so the usefulness of these discharge recommendations is debatable. Large studies, especially in the adult asthmatic population, are needed to validate these recommendation.

Dangerous behaviour preceding first admissions for schizophrenia.

Of 253 patients in their first schizophrenic episode, 52 behaved in a way threatening to the lives of others before their admission to hospital. These 52 patients were studied from data collected at the time of their initial presentation. Despite a history of illness in excess of 1 year in 24 cases, and evidence that violence was motivated by psychotic symptoms in 23 cases, fewer than half of the patients were admitted to hospital as a direct result of their dangerous behaviour. Life-threatening behaviour was more common where the patient had been ill for longer, and where there were delusions of being poisoned.

Further investigation of the predictors of outcome following first schizophrenic episodes.

The outcome at two years of patients who were eligible for a study of first schizophrenic episodes was assessed in terms of occupation (n = 237) and in terms of number of days spent as an in-patient from the time of first admission (n = 252), and was related to social, behavioural, mental state and neurological measures during the initial admission. Poor outcome was in general associated with more social withdrawal, inactivity and abnormal social presentation and with more 'neurological soft signs'. Good occupational outcome in patients with a relatively short pre-treatment duration of illness was associated with the prescription of placebo medication during the follow-up period.

The effect of a nurses' industrial action on psychiatric hospital admissions.

The socio-demographic and clinical characteristics of patients admitted to a large psychiatric hospital during a six month period of industrial action by nurses are described and compared with those from a similar period in the previous year. During the industrial action, the nursing staff agreed only to accept "emergency cases" for admission. The way that medical and social work practices were affected by the restricted conditions are discussed. The admission threshold was raised across all diagnostic categories, although the level of violence and social isolation was markedly less than expected. Chronic patients with a duration of illness of ten years or more were least likely to be admitted during the action. It is probable that some patients were admitted under a compulsory order to facilitate access to in-patient treatment.

The occurrence of organic disease of possible or probable aetiological significance in a population of 268 cases of first episode schizophrenia.

In a sample of 268 cases of first-episode schizophrenia, 15 patients were found to have organic disease which appeared relevant to the mental state. There were three cases of syphilis, two cases of sarcoidosis, three of alcohol excess and two of drug abuse. There was one case each of carcinoma of the lung, autoimmune multisystem disease, cerebral cysticercosis, thyroid disease and previous head injury. In this series, identified organic disease was associated with less than 6% of cases of schizophrenia.

A randomised controlled trial of prophylactic neuroleptic treatment.

Out of 253 patients fulfilling criteria for a first episode of schizophrenic illness, 120 entered a randomised placebo-controlled trial of maintenance neuroleptic medication on discharge; they were followed to relapse or loss to follow-up, for two years or to the end of the study. Of those on active medication, 46% relapsed, as did 62% of those on placebo; the most important determinant of relapse was duration of illness prior to starting neuroleptic medication. This finding might be because extended duration of symptoms before admission is more likely to be present in illnesses which in any case will have poor prognosis, or because susceptibility to relapse is reduced by early institution of treatment. The study provides no data on which a decision between these alternative explanations can be based.

Short-term outcome in trial entrants and trial eligible patients.

Of 253 patients from nine medical centres identified with first episodes of schizophrenic illness, 17 did not achieve discharge during the period of trial recruitment. 120 entered a randomised controlled trial of neuroleptic medication and were followed-up, as were 116 who were eligible for the trial but did not enter it. Overall, 60% of the sample had relapsed within two years of discharge; age, sex, ethnic origin, duration of admission, social withdrawal before admission, and type of onset of illness were not significantly related to relapse. Relapse rates were lower on active trial or standard medication than placebo, but however assessed, outcome at this early stage was poor for many patients.

A magnetic resonance study of early schizophrenia.

Patients with untreated first schizophrenic episodes and others who had made varying degrees of recovery from such episodes were blindly compared with normal volunteers in terms of the periventricular appearances on spin echo magnetic resonance scans. Significant differences were not found.

The Northwick Park Study of first episodes of schizophrenia. I. Presentation of the illness and problems relating to admission.

Patients referred over 28 months from nine medical centres for a trial of prophylactic neuroleptic medication following first episodes of schizophrenic illness (462) were assessed with the Present State Examination, WHO scales for disability, past history, and sociodemographic factors, and a rating of disturbed behaviour; 253 fulfilled the study criteria; of the 209 who did not, 54 did not meet the diagnostic criteria, 65 had a history of a previous episode, and in 15 the psychotic illness was found to have an organic basis. The interval between onset of illness and admission varied widely, but was often more than one year and associated with severe behavioural disturbance and family difficulty e.g. in arranging appropriate care. Current arrangements for initiating management of first schizophrenic illnesses are frequently unsatisfactory.

Expressed emotion and relapse.

The relatives of 82 patients in a study of first episodes of schizophrenia were interviewed within six weeks of the index admission; 77 patients were subsequently discharged, and were followed to relapse or readmission. Analysis of relapse-free survival time was used to examine whether the components of 'expressed emotion' predicted relapse or response to neuroleptic medication: 'critical comments' by relatives was the only component present often enough to be used and was inversely related to 'social contact'. When preadmission duration of illness, and neuroleptic medication following discharge (identified previously as significant predictors of outcome) were taken into account, neither 'critical comments' nor 'social contact' were related to outcome nor to response to medication. The constellation of factors suggested as pathogenic was present only in a minority of cases: many patients lived alone and of those that were with families, most were not in high face-to-face contact with other members. The failure of the components of 'expressed emotion' to predict outcome or response to neuroleptic medication suggests that at best, such factors are weak predictors of liability to relapse. Their influence is unlikely to be comparable in magnitude to that of neuroleptic medication.

Schizophrenic patients discharged from hospital--a follow-up study.

A cohort of 120 patients, comprising all those who met the St Louis criteria for a diagnosis of schizophrenia, discharged from a mental hospital over a five-year period, were followed-up in the community after an interval of five to nine years; 105 were traced and 94 were alive. Of those, 66 were living in UK, out of hospital, and willing to be seen. Their mental states, and social functioning and circumstances were assessed by interview with the patients and those with whom they lived; 18% had recovered to the extent that they had no significant symptoms and appeared to function satisfactorily. More than 50% had definite psychotic features. No patients and few relatives sought a return to hospital care, but severe emotional, social, and financial difficulties were commonplace; 27% of the sample had no contact with medical or social services, a further 14% saw only community nurses, and 24% only their general practitioners. The findings emphasise the limitations of community services in dealing with the chronicity and severity of the impairments resulting from schizophrenic illness.

Institutionalization and the defects of schizophrenia.

Patients conforming to the Feighner criteria for schizophrenia who had been discharged from hospital were traced after 5-9 years. They were assessed in terms of mental state and cognitive, behavioural and neurological functioning; the results of these assessments were related to information obtained from casenotes. The findings of this study of 120 discharged patients were compared with those of an earlier study of 510 in-patients with schizophrenia. When factors of age and duration of illness were taken into account, there was no difference between the two groups in terms of positive or negative schizophrenic features or behavioural performance, although the in-patients performed less well on cognitive tests. This study indicates that the deficits of chronic schizophrenia are an integral feature of the disease process, and that any effects of institutionalisation are relatively small.

Characteristics of patients with schizophrenia or neurological disorder and virus-like agent in cerebrospinal fluid.

A virus-like agent (V.L.A.) with a cytopathic effect on cultured cells was found in the cerebrospinal fluid of 18 of 47 patients with schizophrenia, of whom 10 had nuclear schizophrenic symptoms. In most patients with V.L.A., blood and C.S.F. protein concentrations were normal. Patients with and without V.L.A. had similar clinical characteristics but serum IgA levels were higher in those with V.L.A. V.L.A. was also detected in the C.S.F. of 8 of 11 patients with serious or chronic neurological disease (Huntington's chorea, multiple sclerosis, and unexplained alterations of consciousness).
