Iowa record-linkage study: death rates in psychiatric patients

The Iowa record-linkage study was developed to investigate death rates in psychiatric patients, and involved computer matching of death certificates with a roster of patients. A list of all patients admitted to our hospital from 1972 through 1981 was obtained and after removing duplicate entries the list was pared to 5412 names. The record included multiple identifiers (e.g., name, gender, date-of-birth, hospital number). This information was then linked by computer with all Iowa death certificates for the same period; a total of 331 deaths were identified. Patients were assigned to a single psychiatric diagnostic category based on a computer program that reviewed each patient's clinical diagnoses and picked the one with the highest priority in a hierarchy we had created. Age and sex adjusted mortality tables were constructed, allowing us to compute expected numbers of deaths. Relative risk for premature death was greatest among women, and those under 20 years. Risk was associated with all psychiatric diagnoses and was significantly higher among patients of either gender with an organic mental disorder or schizophrenia; women with acute schizophrenia, depressive neuroses, alcoholism, drug abuse, and psychophysiological disorders; and men with neuroses. Death from natural causes, especially from heart disease, was significantly excessive among women, while death from accidents and suicides was excessive for both men and women. The overall SMR was 1.65 (P < 0.001). Most importantly, we found that the greatest excess of mortality occurred within the first 2 years following hospital discharge. Thus, we were able to demonstrate that risk of mortality in general, and of suicide specifically, differed according to age, gender, diagnosis, and portion of the follow-up. We have subsequently used this method to investigate specific risk factors associated with mortality in mood disorders, schizophrenia, and antisocial personality disorder. Findings from these studies are reported.     

Occurrence and clinical correlates of psychiatric comorbidity in patients with psychotic disorders

BACKGROUND: The aim of this study was to explore patterns and clinical correlates of psychiatric comorbidity in patients with schizophrenia spectrum disorders and mood spectrum disorders with psychotic features. METHOD: Ninety-six consecutively hospitalized patients with current psychotic symptoms were recruited and included in this study. Index episode psychotic diagnosis and psychiatric comorbidity were assessed using the Structured Clinical Interview for DSM-III-R-Patient Version (SCID-P). Psychopathology was assessed by the SCID-P, Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms, and Hopkins Symptom Checklist. Awareness of illness was assessed with the Scale to Assess Unawareness of Mental Disorders. RESULTS: The total lifetime prevalence of psychiatric comorbidity in the entire cohort was 57.3% (58.1% in schizophrenia spectrum disorders and 56.9% in mood spectrum psychoses). Overall, panic disorder (24%), obsessive-compulsive disorder (24%), social phobia (17.7%), substance abuse (11.5%), alcohol abuse (10.4%), and simple phobia (7.3%) were the most frequent comorbidities. Within the group of mood spectrum disorders, negative symptoms were found to be more frequent among patients with psychiatric comorbidity than among those without comorbidity, while such a difference was not detected within the group of schizophrenia spectrum disorders. Social phobia, substance abuse disorder, and panic disorder comorbidity showed the greatest association with psychotic features. An association between earlier age at first hospitalization and comorbidity was found only in patients with unipolar psychotic depression. Patient self-reported psychopathology was more severe in schizophrenia spectrum patients with comorbidity than in those without, while such a difference was less pronounced in mood spectrum psychoses. CONCLUSION: These findings suggest that psychiatric comorbidity is a relevant phenomenon in psychoses and is likely to negatively affect the phenomenology of psychotic illness. Further studies in larger psychotic populations are needed to gain more insight into the clinical and therapeutic implications of psychiatric comorbidity in psychoses.     

Mortality of patients with functional psychiatric illnesses during inpatient treatment

Data from 7 psychiatric hospitals with defined catchment areas were analysed. 8927 episodes of treatment in patients with functional psychiatric disorder were recorded within 30 months (mean age 43.4 +/- 16.6 years; 41.2% male patients). During their stay in hospital 51 patients died, 31 from natural causes and 20 by suicide, compared to 12 deaths expected from the mortality rates of the general population. Standardised mortality ratios (SMRs) were calculated for the different diagnostic and age groups. In the whole population mortality from all causes (SMR 4.27, p < 0.001), as well as from natural causes (SMR 2.6 < 0.01) were significantly raised. Risks were highest in patients with schizophrenia (SMR for all causes of death 6.6, p < 0.001). Mortality from natural causes was significantly elevated in schizophrenia and related disorders. Furthermore, a high level of excess mortality mainly due to suicide was established in patients aged under 45 years (SMR 12.2, p < 0.001). Cardiovascular disorders were the most frequent causes of natural death. Our data substantiate a significantly elevated mortality risk due to natural and unnatural death of patients hospitalised for acute mental illness. Although the causative factors have not yet been fully clarified, prophylactic measures with regard to medical care as well as suicide prevention should be intensified in psychiatric hospitals.     

Suicide and other causes of death in patients admitted for attempted suicide. 10-year follow-up

The purpose of this study has been to describe the course over ten years and prognosis for a cohort of patients who had been admitted to a psychiatric department following a suicide attempt. The cohort consisted of 207 patients who had been admitted in the period 1.10.1980-20.4.1981 to a department of psychiatry following a suicide attempt. At the index attempt 99 patients were randomly selected and interviewed. Information on the remainder was obtained from psychiatric case histories, casualty records and discharge reports. Ten years after the index attempt information concerning death, date and cause was collected. Of the 207 patients involved, 52 (25.1%) were dead. Twenty-five (12.1%) had committed suicide, the remainder had died of natural, accidental or unknown causes. Relative to the general population the death rate from suicide and other causes was extremely high. Predictors of suicidal outcome were substance abuse and dangerous index attempt. At least one of these two predictors was present for 72% of those who committed suicide and for 43% of those who did not commit suicide. Aging and previous suicide attempts were the only significant predictors of other causes of death.     

Avoidable mortality among psychiatric patients

Avoidable mortality is a selection of causes of death considered to be amenable to health care and thereby used as an indicator of the quality of health care. In this study avoidable mortality for more than 30,000 psychiatric patients discharged from any hospital of Stockholm County between 1981 and 1985 has been followed up in the Cause of Death Register for the period 1986-1990. Standardised rate ratios were calculated for different groups of psychiatric disorders compared to the general population of Stockholm County for indicators of avoidable mortality, suicide, other mortality ("unavoidable") and causes possibly related to treatment with psychotrophic drugs. As expected, the psychiatric patients had the most pronounced elevated risk for suicide. i.e. 6- to 24-fold compared to the general population, and noticeably more elevated for women. It is also noteworthy that the relative mortality risks for diagnoses amenable to medical interventions and potential side-effects of psychotrophic drugs are higher than for other causes of death ("unavoidable"). The relative risks for avoidable mortality were 4.7 for men and 3.8 for women and for diagnoses possibly related to side-effects of psychotrophic drugs, 7.2. The relative risks for "unavoidable" mortality were 3.4 for men and 3.2 for women. The excess avoidable mortality rates for psychiatric patients and the elevated suicide risk, especially for female patients, are warning signals of shortcomings in psychiatric care that warrants further investigation.     

The risk of suicide

HISTORICAL PERSPECTIVE: A certain number of historical elements including the progressive loss of religious values and the fact that suicide is considered to be an integral part of medical knowledge must be taken into consideration when assessing the risk of suicide. The sociological and psychoanalytical approaches attempt to help draw the suicidal subject out of the his/her personal implication by affecting the social and subconscious aspects of the problem respectively. Other elements such as psychiatric, sociocultural, biological and psychopathological factors are also involved in evaluating the risk of suicide. RISK FACTORS: Durkheim's analysis of the social, familial and occupational factors observed in suicide remains pertinent for assessing risk. Psychiatric disorders are also highly significant risk factors since some type of disorder is found in approximately 90% of all suicide victims. Affective disorders including rapidly alternating bipolar behavior, psychoses, particularly schizophrenia, and borderline personality are the most frequently observed, especially when associated with certain types of behavior such as drug or alcohol abuse. The risk related to other factors such as suicidal behavior (attempts or ideation) is independent of the psychiatric illness. For example, the risk of successful suicide is 30 greater the year after an attempted suicide than in the normal population. ASSESSING RISK: There are no known clinical means, notably psychometric, which can successfully predict the imminence of suicide. Recent studies on brain monoamine levels have shown that a lower 5-HIAA level does play some role in suicidal behavior, particularly violent suicide, although there is no predictive power for normality. It is important to recall that certain advances in the field of psychopathic illnesses offer new insight into concepts such as the death instinct and the suicidal act itself.     

Psychiatric morbidity among adults in The Netherlands: the NEMESIS-Study. II. Prevalence of psychiatric disorders. Netherlands Mental Health Survey and Incidence Study

OBJECTIVE: To determine the prevalence of psychiatric disorders in non-institutionalised Dutch adults. DESIGN: Cross-sectional. SETTING: Trimbos Institute, Utrecht, the Netherlands. METHODS: A representative sample of 7076 adults (18-64 years) in the Netherlands' population were interviewed in 1996 to determine the prevalence of mental disorders ever, in the previous 12 months and in the previous month. Objectives and study design are described in the previous article (1997: 2448-52). The 'Composite international diagnostic interview' (CIDI) was used to assess the following mental disorders according to Diagnostic and statistical manual of mental disorders, 3rd revised edition (DSM-III-R): affective disorders, anxiety disorders, eating disorders, schizophrenia and other non-affective psychoses, substance dependence and substance abuse. RESULTS: Mental disorders were common in the general population: the prevalence 'ever' of all disorders was 41.2%, the 12-month prevalence 23.5%, without sex differences. Depression, anxiety disorders and alcohol abuse and dependence showed high prevalence and comorbidity. The prevalence 'ever' of schizophrenia and other non-affective psychoses was low (0.4%).     

Toward a clinical model of suicidal behavior in psychiatric patients

OBJECTIVE: Risk factors for suicide attempts have rarely been studied comprehensively in more than one psychiatric disorder, preventing estimation of the relative importance and the generalizability of different putative risk factors across psychiatric diagnoses. The authors conducted a study of suicide attempts in patients with mood disorders, psychoses, and other diagnoses. Their goal was to determine the generalizability and relative importance of risk factors for suicidal acts across diagnostic boundaries and to develop a hypothetical, explanatory, and predictive model of suicidal behavior that can subsequently be tested in a prospective study. METHOD: Following admission to a university psychiatric hospital, 347 consecutive patients who were 14-72 years old (51% were male and 68% were Caucasian) were recruited for study. Structured clinical interviews generated axis I and axis II diagnoses. Lifetime suicidal acts, traits of aggression and impulsivity, objective and subjective severity of acute psychopathology, developmental and family history, and past substance abuse or alcoholism were assessed. RESULTS: Objective severity of current depression or psychosis did not distinguish the 184 patients who had attempted suicide from those who had never attempted suicide. However, higher scores on subjective depression, higher scores on suicidal ideation, and fewer reasons for living were reported by suicide attempters. Rates of lifetime aggression and impulsivity were also greater in attempters. Comorbid borderline personality disorder, smoking, past substance use disorder or alcoholism, family history of suicidal acts, head injury, and childhood abuse history were more frequent in suicide attempters. CONCLUSIONS: The authors propose a stress-diathesis model in which the risk for suicidal acts is determined not merely by a psychiatric illness (the stressor) but also by a diathesis. This diathesis may be reflected in tendencies to experience more suicidal ideation and to be more impulsive and, therefore, more likely to act on suicidal feelings. Prospective studies are proposed to test this model.     

Individual differences in spatial organization of cortical electrical activity during formation of a set to visual stimuli

Vascular affections of the brain remain a formidable psychiatric challenge nowadays. According to WHO reports cerebrovascular disorders constitute one of the three chief causes of mortality in the population of the economically developed countries of the world. The most important cause of vascular psychoses is considered to be atherosclerosis and hypertensive disease. Today vascular psychoses have become a most common type of abnormal mental states in young adults (greater then 30-40 years old). The studies made have yielded evidence in support of the psychoses morbidity to be dependent upon particular season of year as well as on the climatic features of the locality. Natural factors have been found out to affect the prevalence of vascular psychoses in Chernivtsi Province. The findings obtained suggest to us a substantial prevalence of atherosclerotic and hypertensive psychoses in the plains-men living under conditions of a mild climate.     

Sex differences in mortality of people who visited emergency rooms for asthma and chronic obstructive pulmonary disease

We assess the sex differences in mortality in a population-based cohort of those Barcelona residents older than 14 yr of age who received emergency room services (ERS) for either chronic obstructive pulmonary disease (COPD) or asthma, during the period from 1985 to 1989. Vital status was followed to the end of 1995. A total of 15,517 individuals, 9,918 males and 5,599 females were included in the study. Asthma was diagnosed in 16% of males and 53% of females. Overall, 50% of males and 30% of females died during the follow-up period. The mortality rates in both males and females who visited emergency rooms for COPD or asthma were significantly higher than the expected rates in the general population. These relative increases in the mortality rates were significantly higher in females than in males for both causes of death, COPD (age-adjusted female/male ratio = 2.39), and asthma (ratio = 3.95). However, survival was better in females than males among individuals in the study. The higher fatality in males than females was observed for all causes of death, all respiratory causes, and COPD (risk ratio among patients with COPD = 0.42, 0.29-0.59, and among patients with asthma = 0.11, 0.02-0.60), but not for asthma. Mortality for asthma was higher in females with a diagnosis of COPD (2.79, 1.52-5.13), but it was not different among individuals in whom asthma was diagnosed (1.02, 0.56-1.87). Greater severity of COPD in males than in females could explain a higher risk of dying for all respiratory causes and COPD in males. The increased risk of asthma death in females may be due to problems of coding the term "asthma" in death certificates. The higher rates in females than in males when comparing with the general population, may be an expression of a greater similarity in risk factors, such as smoking, in our population than in males and females of the general population.     

Clinico-epidemiologic study of the mental state of a group of elderly persons from the general population

A clinico-epidemiological study of a representative group of individuals older than 60 years of age from the general city population demonstrated that by far not all mental disorders of old age come into contact with a psychiatrist. A study of 1020 individuals (361 males and 659 females) detected 23 patients (2.3% of the studied population), who suffered from psychotic conditions and who were not registered in the neurophsychiatric dispensary: 6(0.6%) with schizophrenia, 6 (0.6%) -- with delusional psychoses of old age, 9 (0.9%) -- with vascular and senile psychoses and 2 (0.2%) -- with exogenous -- organic psychoses. Besides, in 29 cases (2.8%) there were signs of expressed organic dementia. In 38.9% of the studied individuals there were different mental abnormalities not attaining a psychotic level (initial weakly pronounced and mild psychoorganic conditions).     

Mortality in psychiatric hospital patients: a cohort analysis of prognostic factors

BACKGROUND: This work followed a group of patients living in a psychiatric hospital in Central Italy in 1978 at the time of enforcement of the Italian reform law (No. 180) for closing down mental hospitals. The study had the following aims: a) to compare in terms of mortality patients discharged into the community with patients who did not experience deinstitutionalization; b) to determine the survival of the cohort of patients and to analyse prognostic risk factors for death; c) to analyse differences in mortality rates between psychiatric patients and the general population. METHODS: The study was designed as an historical follow-up investigation. Univariate (product limit) and multivariate (proportional hazards model) methods were used to estimate prognostic variables and related death risks. Mortality was assessed using standardized mortality ratios (SMR) on the entire cohort as well as after stratification according to age, sex, cause of death and discharge status, assuming the Abruzzo Region's population as standard. RESULTS: Length of hospitalization and discharge from hospital are prognostic variables for death risk, with relative risks respectively of 4.22 (95% confidence interval [CI]: 2.41-7.40) for a length of hospitalization of 10-25 years, and 8.13 (95% CI: 4.73-13.88) for non-discharge. The global SMR of the cohort was 2.68 (95% CI: 2.42-3.07). Non-discharged patients showed higher SMR than discharged. Excess mortality was found both in males and females for circulatory, respiratory and undefined diseases. A significantly lower mortality for cancer was observed in male patients. A strong excess mortality was observed in younger patients (20-29 years: SMRmales = 43.57; SMRfemales = 97.52). CONCLUSIONS: Longer periods of hospitalization and non-discharge from hospital are the main risk factors for death in psychiatric patients, who globally experience higher death rates than the general population for a wide spectrum of causes of death, whatever their diagnosis or gender. These findings strongly suggest positive actions in order to overcome the effects of institutionalization.     

Histological features of the contralateral ovary in patients with unilateral ovarian cancer: a case control study

It has been suggested that schizophrenia and alcoholism are associated with violent behavior. But so far there are no published studies from unselected cohorts quantifying the actual risk associated with schizophrenia both with and without comorbid alcoholism. In this study, an unselected birth cohort (n = 11,017) was prospectively followed to the age of 26, and data on psychiatric disorders and crimes were collected from national registers. The odds ratios for violent offenses and recidivism were calculated for each diagnostic group. Men who abused alcohol and were diagnosed with schizophrenia were 25.2 (95% confidence interval (CI) 6.1-97.5) times more likely to commit violent crimes than mentally healthy men. The risk for nonalcoholic patients with schizophrenia was 3.6 (95% CI 0.9-12.3) and for other psychoses, 7.7 (95% CI 2.2-23.9). None of the patients with schizophrenia who did not abuse alcohol were recidivists (> 2 offenses), but the risk for committing more crimes among alcoholic subjects with schizophrenia was 9.5-fold (95% CI 2.7-30.0). This study suggests that to prevent the crimes being committed by people with schizophrenia, it is important that clinicians watch for comorbid alcohol abuse.     

Biochemistry and biomechanics of healing tendon: Part I. Effects of rigid plaster casts and functional casts

OBJECTIVE: The state psychiatric hospital is experiencing an increase in medically sick and aging patients who die of natural causes while hospitalized. This study explored the "medicalization" of the state hospital by examining the prevalence of medical illness and its relationship with psychiatric illness and age among state hospital psychiatric inpatients who died of natural causes--deaths that were not accidents, homicides, or suicides. METHODS: A total of 179 inpatients who died of natural causes at Western State Hospital in Washington State between 1989 and 1994 were studied retrospectively through case file review. Their demographic and institutional characteristics and psychiatric diagnoses were compared with those of others treated at the hospital (N=9,258). The medical diagnoses of patients who died were analyzed by age and psychiatric condition. RESULTS: The patients who died were much older than the other patients treated during the study period. Two-thirds of those who died had organic mental disorders, mostly dementia, whereas only a fifth of the other patients had these disorders. The patients who died had a mean of eight physical illnesses, with a range from none to 21. Circulatory and respiratory conditions were most prevalent, affecting half to two-thirds of patients; these conditions had high rates of comorbidity with organic mental disorders. CONCLUSIONS: The characteristics of the state hospital population and the services provided are shifting in response to mental health reform and new policies on patient self-determination. Increased emphasis on medical care added to traditional psychiatric services will require increased financial and personnel resources.     

Psychiatric disability in Ontario

OBJECTIVE: To describe the disability associated with psychiatric disorder in a community sample in order to refine estimates of service need and identify subgroups with greater priority for intervention. METHOD: Disability is conceptualized broadly as performance difficulties, troubled relationships, and dissatisfaction in various life domains. Data from the Mental Health Supplement are used to compare disability between those with and without disorder and among various subtypes of disorder. RESULTS: Although the majority of those with disorder do not report disability, their difficulties with functioning are far greater than for the rest of the population. Those with comorbid or affective disorders typically have more disability than those with anxiety or substance abuse disorders. CONCLUSIONS: Society needs to recognize the high human and economic costs associated with the prevalence of psychiatric disorder. Assessments of service need and decisions about priorities should take both disorder and disability into consideration.     

Screening and treatment of distress.

The screening and treatment of psychological distress is an increasingly important aspect of providing comprehensive care to medical patients. The importance of this within oncology was illustrated most recently by the publication of the National Comprehensive Cancer Network's Distress Guidelines (Holland, 1997). Given that measures of general distress assess for symptoms across diagnostic categories, it is not unusual to have a combination of symptoms indicating distress without meeting diagnostic criteria (Derogatis, Morrow, & Petting, 1983). We would suggest that general measures of distress and psychiatric diagnoses not assessed by Coyne et al. (e.g., somatoform or adjustment disorders) may reflect better the distress (health anxiety and somatic preoccupation) of women at increased risk for cancer and be more informative than assessing selectively for mood disorders, anxiety disorders, and alcohol abuse. The authors additionally concluded that if there is not psychiatric disorder, then there is no impairment. We believe it premature at best to reify the DSM in a nonpsychiatric population. Distress exists on a continuum. To wait until patients meet psychiatric criteria before they are seen is not in the spirit of comprehensive medical care.

Corticobasal degeneration: clinical features

BACKGROUND: There are little epidemiologic data on psychiatric disorders of women in jails. Accurate data on female jail detainees are critical because of their increasing numbers and their unique treatment needs. METHODS: Using the Diagnostic Interview Schedule, independent interviewers assessed a randomly selected, stratified sample of 1272 female jail detainees awaiting trial in Chicago, Ill. We tabulated lifetime and 6-month prevalence rates of disorders by race or ethnicity (African American, non-Hispanic white, Hispanic), age, and education and compared the jail rates with general population rates for women in the Epidemiologic Catchment Area program. We also examined whether or not psychiatric disorder was associated with the severity of the detainee's current arrest charges. RESULTS: Over 80% of the sample met criteria for one or more lifetime psychiatric disorders; 70% were symptomatic within 6 months of the interview. The most common disorders were drug abuse or dependence, alcohol abuse or dependence, and post-traumatic stress disorder. Major depressive episode was the most prevalent major mental disorder. Rates were generally highest among non-Hispanic whites and among older detainees. Rates for all disorders were significantly higher than general population rates, except for schizophrenia. Most detainees with psychiatric disorders were arrested for nonviolent crimes. CONCLUSION: These results suggest substantial psychiatric morbidity among female jail detainees.     

Psychiatric hospitalization of senile and arteriosclerotic dementia patients by commitment order under the 1991 Israeli Mental Health Act

Data regarding commitment orders issued by district psychiatrists for elderly patients aged 65 years or older were obtained from the national psychiatric case register. Out of a total of 2,284 commitment orders issued in Israel in the period 1 January 1992 to 30 June 1993 under the 1991 Mental Health Act, 191 (8.3%) involved patients aged 65 and over; these orders were issued for the commitment of 169 patients who suffered from the following ICD-9-CM diagnoses on discharge: senile and arteriosclerotic dementia; transient organic psychotic conditions; schizophrenic disorders; affective psychoses; paranoid states; or other psychiatric disorders. Demographic and clinical characteristics of the senile and arteriosclerotic dementia patients were compared with the same variables in the other diagnostic categories. Results showed that (a) involuntary commitment of senile and arteriosclerotic dementia patients involved a small minority of dementia sufferers; (b) it was usually the patients' first psychiatric admission; (c) most of the patients were discharged within a one-month period; and (d) most of the patients were referred for continuation of treatment in non-psychiatric institutions. Findings (c) and (d) characterized other diagnostic categories as well. The relevance of these findings to the Mental Health Act is discussed.     

Course of psychiatric and substance abuse syndromes co-occurring with bipolar disorder after a first psychiatric hospitalization

BACKGROUND: Patients with bipolar disorder frequently meet criteria for other psychiatric and substance abuse diagnoses. To clarify relationships among these disorders, the authors examined the course of syndromes co-occurring with bipolar disorder for 12 months after a first hospitalization. METHOD: Seventy-seven patients were recruited from consecutive inpatient admissions who met DSM-III-R criteria for bipolar disorder, manic or mixed with psychosis. The 12-month syndromal course of co-occurring DSM-III-R alcohol and drug abuse disorders, posttraumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), and other anxiety disorders were longitudinally recorded. RESULTS: The rates of all syndromes, except other anxiety disorders, were elevated. OCD demonstrated an interval course that frequently mirrored the course of the bipolar disorder. The courses of PTSD and substance abuse syndromes were separate from that of the bipolar disorder in many of those with both syndromes. Alcohol and drug abuse syndromes were strongly correlated. CONCLUSION: The obsessive-compulsive syndrome may represent an alternative expression of bipolar disorder in some patients. In contrast, PTSD appears to represent a truly separate disorder, which is possibly more prevalent in bipolar patients due to a shared risk factor. Substance abuse does not appear to simply result from attempts at self-medication or from the impulsivity of mania. These results suggest that future studies examining the course of syndromes co-occurring with bipolar disorder are warranted.
