Identifying psychiatric suicides for research purposes.

Unusual accidental deaths recorded for former public psychiatric patients during a 3-year period in Missouri were compared with data previously published on suicide and undetermined deaths. Demographic and diagnostic data suggested that undetermined deaths resemble suicides, while the remaining unusual accidents do not. For purposes of estimating incidence or prevalence, it is recommended that "undetermined deaths" might well be combined with suicides, while the remaining accidents should not.

What is measured when we identify alcoholics by means of blood tests?

Positive results have been reported on discriminating between alcoholic and nonalcoholic patients by means of multivariate analysis of blood chemistry. If such tests simply measure accumulated results of excessive drinking, the measured effect would increase with years of severe drinking. Data from records of 460 alcoholics, however, found little or no relationship. The authors suggest the possibility that the blood chemistry results may measure a constitutional vulnerability to alcoholism.

The Missouri Inpatient Behavior Scale.

The Missouri Inpatient Behavior Scale (MIBS) is described, and data are presented from the Missouri automated mental health information system (N = 12,106). The factor structure for MIBS was replicated and shown to be robust. Data on intrascale consistency and interscale correlations are presented, as well as a validity study that showed MIBS to be sensitive to changes on acute-receiving services and a comparison of MIBS and NOSIE-30 scores.

The Missouri Alcoholism Severity Scale: relationship with type of alcohol consumption.

Data on 10,562 alcoholics treated in public programs in Missouri were retrieved from a statewide computerized mental health information system. Scores on the Missouri Alcohol Severity Scale were correlated with various symptom data, including average amount of beer, wine and distilled spirits ingested. Severity scores were primarily related to consumption of distilled spirits and the emergence of physical-medical symptoms. Correlations with beer drinking were higher for women than for men. A subsample of 889 alcoholics who drink beer only tended to be middle-aged, relatively stable, White men with less severe symptoms than other alcoholics.

Self-induced water intoxication: a comparison of 34 cases with matched controls.

Of 2201 psychiatric patients in public facilities in a single metropolitan area evaluated for polydipsia, 34 (1.5%) were found to have a history of self-induced water intoxication. Among them, they had 101 episodes of water intoxication. Their mean age was 48.2 years, and they were predominantly white. Most had the primary diagnosis of schizophrenia. Compared with a matched control group, they had received more multiple courses of ECT but there were no significant differences in their use of psychotropic medications. Among nonpsychiatric medications, only phenytoin sodium and hydrochlorothiazide showed a trend toward significance.

Mortality variations among public mental health patients.

Earlier studies of mortality of psychiatric patients are reviewed, and agreements and inconsistencies related to age, sex, diagnosis and cause of death are noted. The authors then analyze 5,268 deaths during a 5-year period of current or former patients in Missouri public psychiatric hospitals and mental health clinics, calculating mortality ratios that are simultaneously age-, sex-, diagnostic-, and cause-specific. The results are used to construct a quantitative model. The ratios vary most with cause, then diagnosis, least with sex. Influenza and pneumonia contribute most to patient mortality; patient death rates for cancer are lower than population rates at all ages. There are substantial interactions of diagnosis with cause and sex. Among those diagnosed organic brain syndrome, who have the highest overall ratios, the ratios are extra high for females and for influenza and pneumonia, relatively low for external causes.

Biochemical diagnosis of alcoholism in men psychiatric patients.

A comparison was conducted of several discriminant models (linear, stepwise linear and quadratic) using two definitions of prior probability (proportional and equal) to detect alcoholism on the basis of routine blood test results. Discriminant functions were derived on a sample of men alcoholic (N = 407) and nonalcoholic (N = 1068) psychiatric patients, and were cross-validated on an independent sample of the same two populations (NS = 365 and 1020, respectively). Linear discriminant models generally outperformed quadratic models. The best classification was obtained by the equal stepwise linear model that retained SGOT, calcium, albumin, inorganic phosphate and BUN. The best quadratic model (equal) achieved good overall accuracy but weak sensitivity. The linear model was relatively accurate in terms of classification, and better sensitivity was achieved with the five best predictors than with all available measures.

Prediction of readmission in a cohort of alcoholics: a 2-year follow-up.

A cohort of 1,192 first admissions to metropolitan public alcohol treatment programs was examined after 2 years. With the sample sub-divided by number of readmissions, discriminant analysis based on demographic data, social history, and current drinking behavior provided only modest prediction of group membership (k = .46), but may be sufficient to provide an alerting function for recidivism.
