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 after discharge from psychiatric inpatient care

People with a history of psychiatric disorder are at higher risk of suicide than people without such a history. The policy of reducing inpatient care in psychiatry has probably meant that some of the risk of suicide has shifted from the hospital to the community setting. We have quantified the risk of suicide within a year of psychiatric discharge in a population-based study in the Oxford health region, UK. We calculated suicide rates per 1000 person-years at risk (time from discharge to death, subsequent readmission, or the end of the study) and the standardised mortality ratio (SMR) for suicide, taking the value among the general population as 1. Among male patients the SMR for suicide (defined by coroner's verdict of suicide) in the first 28 days after discharge from inpatient care was 213 (95% CI 137-317); the equivalent SMR for female patients was 134 (67-240). The result was similar when we defined suicide more broadly as a suicide, open, or misadventure verdict. The suicide rate in the first 28 days after discharge was 7.1 (4.1-12) times higher for male patients and 3.0 (1.5-6.0) times higher for female patients than the rate during the remaining 48 weeks of the first year after discharge. Most of the patients studied (both those who committed suicide and those who did not) had been psychiatric inpatients for only a short time. The findings confirm that there is significant clustering of suicide soon after discharge from psychiatric care. Skilled support after discharge for high-risk patients in the community is essential. Audit of suicides that occur soon after discharge may help identify the patients at highest risk and thereby reduce the number of avoidable deaths.     

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.     

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.     

Changes in the pattern of drug overdoses

OBJECTIVE: To describe changes in the pattern of patients with drug overdoses hospitalized over the past two decades. DESIGN: Retrospective data review. SETTING: A 719-bed university-affiliated hospital. PATIENTS: All adults admitted to the hospital with drug overdoses in 1968, 1979, and 1989. PRIMARY OUTCOME MEASURES: Changes in demographics, drugs used, and discharge disposition. RESULTS: A majority of patients admitted with drug overdoses have had previous suicide attempts; and while women predominate, they make up a decreasing proportion of admissions over time (76% in 1968 to 52% in 1989 (p = 0.003). Benzodiazepines were the drugs most commonly used in 1979 and 1989, and cocaine has shown a marked increase in use over time, while barbiturate overdoses have progressively decreased. The use of two or more drugs is common and has been consistent over time, as has been the concomitant use of alcohol. The mortality rate has remained low at 1%, but mean length of stay has decreased dramatically from 6.6 days in 1979 to 3.2 days in 1989 (p < 0.001) and discharge disposition has shifted from out-patient to inpatient psychiatric care. CONCLUSIONS: The majority of patients admitted to a general acute care hospital following a drug overdose have a history of previous suicide attempts and are followed by a mental health professional. The changing pattern of drugs used over two decades reflects trends in drugs used in the community in general and by patients with mental illness in particular. Discharge disposition has changed over time and is related to patients' insurance status.     

Performance of a commercial polymerase chain reaction test for endocervical Chlamydia trachomatis infection in a university hospital population

The rate of survival and causes of mortality in a cohort of 2103 psychiatric patients registered on a psychiatric case register and followed up for 7 years are compared with those of a general population sample (n = 2382) randomly extracted from the municipal census in Valencia (Spain). Using multivariate analysis by Cox regression, patients suffering organic psychoses and those diagnosed with drug abuse or dependency exhibited a greater risk of death than the general population for the total causes of death; no interaction was found between sociodemographic variables and psychiatric pathology. In terms of the causes of death, and controlling for the effect of age and sex, organic psychoses involved a greater risk of death due to cardiovascular and respiratory causes, and a greater risk of non-natural deaths than the general population. Schizophrenia and related conditions, the abuse of alcohol/ other drugs, and neurosis/personality disorders all presented a higher risk of death from liver disease. The major affective disorders involved a greater risk of death due to suicide or accidents. The study concludes with a discussion of the possible explanations of these results.     

Adolescents'' experiences of anger in a residential setting

The most common types of psychiatric diagnoses linked with substance abuse or dependence in women are defined and discussed. A framework is described to facilitate the nurse provider's understanding of the various relationships psychiatric symptoms can have to substance-using patterns. Guidelines are provided to assist the nurse in identifying problems of dual diagnoses and providing care to women with dual diagnoses in general care settings.     

Race Disparities in Psychiatric Rates in Emergency Departments.

Psychiatric diagnoses based on the International Classification of Diseases--Ninth Revision were examined in the medical discharge records of 33,000 emergency department (ED) patients to determine if (a) psychiatric disorders were underdiagnosed, (b) there were race and gender disparities in psychiatric rates, and (c) psychiatric rates varied as a function of type of injury (e.g., self vs. other-inflicted injuries) and medical diagnosis. The observed psychiatric rate of 5.27% was far below the national prevalence rate of 20%-28%. Both race groups were underdiagnosed, but the underdiagnosis was larger for African Americans. Younger patients had fewer psychiatric diagnoses than older patients. Men had more psychiatric diagnoses overall, whereas women had more mood and anxiety diagnoses. Self-injury patients had much higher psychiatric rates than the other injury groups. This psychiatric underdiagnosis contributes to needless emotional suffering, especially for minorities and the poor who rely on EDs for most of their health care.

Potentially avoidable hospitalizations: inequalities in rates between US socioeconomic groups

OBJECTIVES: The National Hospital Discharge Survey (NHDS) was used to evaluate potentially avoidable hospital conditions as an indicator of equity and efficiency in the US health care system. METHODS: With the use of 1990 data from the NHDS, the National Health Interview Survey, and the census, national rates of hospitalization were calculated for avoidable conditions by age, race, median income of zip code, and insurance status. RESULTS: An estimated 3.1 million hospitalizations were for potentially avoidable conditions. This was 12% of all hospitalizations in 1990 (excluding psychiatric admissions, women with deliveries, and newborns). Rates of potentially avoidable hospitalizations were higher for persons living in middle- and low-income areas than for persons living in high-income areas, and were higher among Blacks than among Whites. These class and racial differences were also found among the privately insured. Differences among income and racial groups for persons aged 65 and over were not significant. CONCLUSIONS: Inequalities in potentially avoidable hospitalizations suggest inequity and inefficiency in the health care delivery system. Avoidable hospital conditions are a useful national indicator to monitor access to care.     

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.     

Relationships among suicide ideators, attempters, and multiple attempters in a young-adult sample

The relationships among suicide ideators, attempters, and multiple attempters were explored in 332 psychiatric patients referred specifically for suicidal ideation or behavior. Previous researchers have subsumed multiple attempters under the general category of attempters. However, comparisons across a range of variables, including Axis I diagnoses from the revised 3rd edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1987) depressive and anxiety symptoms, suicidal ideation, hopelessness, problem solving, and a range of personality features revealed that multiple attempters presented a more severe clinical picture and, accordingly, elevated suicide risk compared with attempters and ideators. Observed differences between groups were maintained when attempters with "questionable intent" (i.e., those making equivocal attempts) were excluded from the analyses.     

Suicide following an inpatient hospitalization for a suicide attempt: a Canadian follow-up study

This study contributes a Canadian perspective to a growing body of international studies examining suicide among cohorts of suicide attempters, and a much more limited literature on the epidemiology of suicide in Canada. We evaluated the 13-year mortality experience of a regional cohort of 876 first-ever inpatient hospital admissions for a suicide attempt admitted between 1979 and 1981. Compared to the general population, study subjects were 4 times more likely to die of any cause, but 25 times more likely to commit suicide and 15 times more likely to die of accidental or adverse causes. Ten years after then first hospitalization for attempted suicide, 5.9% of study subjects had committed suicide. Baseline age appeared to be a risk factor for women, but not for men. Women under 60 years had the best 10-year survival (3.6% had committed suicide) and women over 60 years had the poorest (17.5%). A total of 8.7% of men under 60 years and 10% of those over 60 years committed suicide within 10 years. The remainder of the analysis focused on those under 60 years of age at the time of their index inpatient hospitalization. Three factors were prognostic for suicide: being male, which had a relative risk (RR) of 5.0, living in a lower income area (RR = 3.2), and having used a violent method during the index attempt (RR = 2.5). The periods of greatest risk for suicide were within the 1st and 4th years following first-ever inpatient hospitalization, with the 4th year representing the time of highest risk. The identification of time periods subsequent to first-ever hospitalization when patients are at greatest risk of suicide can be used to guide the timing and duration of clinical interventions and aftercare to ensure that patients are appropriately supported during periods of highest risk.     

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.     

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.     

External causes of death among persons with developmental disability: the effect of residential placement

The authors analyzed death rates from external causes (accidents, injuries, homicides, etc.) for persons with developmental disability in California. There were 520 such deaths during the 1981-1995 study period, based on 733,705 person-years of exposure; this represents all persons who received any services from the state. Compared with the general California population, persons with developmental disability were at lower risk of homicide, suicide, and poisonings (standardized mortality ratios, 0.31-0.68), but higher risk of pedestrian accidents, falls, fires, and, especially, drowning (standardized mortality ratio=6.22). A major focus of the study was comparisons between different residential settings. Persons in semi-independent living had significantly higher risk than did those in their family home or group homes, with homicides rates being three times higher and pedestrian accidents rates being doubled, while persons in institutions had much lower risks with respect to most causes. Of the 28 deaths due to drug and medication overdoses, 79 percent occurred in supported living or small-group homes. Avoidable deaths could be reduced by making direct care staff more aware of the risks and better trained in acute care, along with improved monitoring of special incidents.     

Pre-AIDS mortality from natural causes associated with HIV disease progression: evidence from the European Seroconverter Study among injecting drug users

OBJECTIVES: To study differences in pre-AIDS mortality between European cohorts of injecting drug users (IDU) and to evaluate whether pre-AIDS mortality increased with time since HIV seroconversion and decreasing CD4 count. METHODS: The study population consisted of 664 IDU with documented intervals of HIV seroconversion from eight cohort studies. Differences in pre-AIDS mortality were studied between European sites; an evaluation of whether pre-AIDS mortality increased with time since HIV seroconversion and decreasing CD4 count was carried out using Poisson regression. RESULTS: One hundred and seven IDU died, of whom 57 did not have AIDS. Pre-AIDS causes of death were overdose/suicide (49%), natural causes such as bacterial infections/cirrhosis (40%), and unintentional injuries/unknown (11%). Considering pre-AIDS death and AIDS as competing risks, 14.7% were expected to have died without AIDS and 17.3% to have developed AIDS at 7 years from seroconversion. No statistically significant differences in pre-AIDS mortality were found between European regions, men and women, age categories and calendar time periods. Overall pre-AIDS mortality did not increase with time since seroconversion, but did increase with decreasing CD4 count. Evaluating cause-specific mortality, only pre-AIDS mortality from natural causes appeared to be associated with time since seroconversion as well as immunosuppression. For natural causes, the death rate per 100 person-years was 0.13 the first 2 years after seroconversion, 0.73 in years 2-4 [risk relative (RR) to years 0-2, 5.6], 1.83 in years 4-6 (RR, 14.0) and 1.54 for > or = 6 years (RR, 11.7). This rate was 0 for a CD4 cell count > or = 500 x 10(6)/l, 1.06 for 200-500 x 10(6)/l and 4.06 for < 200 x 10(6)/l (RR versus > or = 200 x 10(6)/l, 7.0). In multivariate analysis, both CD4 count and time since seroconversion appeared to be independently associated with death from natural causes; CD4 count appeared to be the strongest predictor (adjusted RR, 5.9). CONCLUSIONS: A high pre-AIDS mortality rate was observed among IDU. No significant differences were observed across European sites. Pre-AIDS mortality from natural causes but not from overdose and suicide was associated with HIV disease progression.     

Metabolism of superoxide dismutase during the adynamic ileus of endotoxemia

The course of the psychiatric in-patient treatment received by 34 young people aged 15-24 years before their deaths from suicide was studied retrospectively on the basis of medical records. The quality of the care that they were given was appraised in terms of continuity, an important aspect of the care of young individuals during a period of dynamic development. There were two suicides among patients in child psychiatric care and 32 suicides among those in adult psychiatric care. Continuity of child psychiatric care was satisfactory, while the striking discontinuity in adult psychiatric care, in terms of contacts with doctors, therapists and other staff, with from 3 to 30 different doctors being involved during the period of care, may have been a factor contributing to the suicidal outcome in these cases. In total, 20 of the 34 young people had reported previously known suicide attempts, and notes concerning suicidal communication were mentioned in all but three of the records, while in only three of the records had any form of suicide-risk assessment been noted at the last care session before the suicide. Information about the suicidal process was thus available for most of these records but, as a rule, suicidal analyses were nevertheless lacking.     

Psychiatric diseases and their treatment in general practice in Germany. Results of a World Health Organization (WHO) study

As part of an international study initiated by the World Health Organization (WHO) about psychological disorders in primary health care, patients in the Federal Republic of Germany were compared with patients in other European centres. Patients from Germany do not differ from other European patients in respect to sociodemographic variables or psychiatric disorders. The most frequent CIDI-based diagnoses recorded in patients attending general practices are current depressive episodes (8.6%), generalized anxiety disorders (8.5%), neurasthenia (7.5%), and alcohol dependence (6.3%). In 20.9% of the patients at least one psychiatric diagnosis based on ICD-10 was recorded. In Germany significantly lower global ratings of health status are given than in other European centres although there is no difference in diagnostic prevalence rates. The recognition rate, i.e. the agreement between the CIDI-based ICD-10 diagnoses and the recognition as a case by the physician, is 56.2%-60.2%. On the other hand, the CIDI detects 90% of the patients described as psychologically ill by the physicians if subthreshold cases are also counted, or 46.4% if only defined diagnoses are taken into account. There is a significant correlation between severity of the psychiatric disorder and disability in social functioning. In Mainz and in the other European countries the disability rate of patients with a well-defined disorder is between 67.0% and 72.7%, whereas in Berlin this relation is not as clear, because especially in East Berlin there is a higher rate of unemployment in view of the political situation. Drug treatment is prescribed for 16.1% of the patients in primary care for psychiatric disorders. Half the patients recognized by physicians as cases receive medication. In the rest of Europe patients receive significantly more tranquillizers than in Germany, where the use of herbal drugs is more wide spread.     

Treatment of ureteral stones: comparison of extracorporeal shock wave lithotripsy and endourologic alternatives

Demographic data, personal and familial characteristics, as well as DSM-III-R-based psychiatric diagnoses were collected in 369 adolescents and young adults aged between 15 and 29 years, referred to an Emergency Department for psychological problems. In total, 60% of them were suicide attempters. Separations before the age of 12 years and depression in the family emerged as the main features distinguishing the suicidal group from the psychiatric control group. Fifty per cent of suicide attempters were repeaters. Fostering during childhood, suicide attempts and depression in the family were found to be risk factors for repeated self-attempts. These results support the view that significant levels of dysfunction, together with increased psychiatric morbidity, especially suicidal behaviour, characterize the families of young self-attempters.     

Psychiatric assessments of nursing home residents under OBRA-87: should PASARR be reformed? Pre-Admission Screening and Annual Review

OBJECTIVE: As part of nursing home practice reforms, OBRA-87 mandates formal psychiatric assessments (PASARR) of nursing home residents suspected of having mental disorders, a responsibility it delegates individually to states. We describe the initial year of implementation of the PASARR process in King County, Washington, and characterize the mental disorders and mental health services needs of nursing home residents referred for psychiatric screening. DESIGN: Cross-sectional study. SETTING: The 54 Medicare-certified King County nursing homes (total beds = 7013). PARTICIPANTS: All patients referred for psychiatric evaluation under PASARR (n = 510). MEASUREMENTS: A systematic, multidimensional evaluation including a semistructured psychiatric diagnostic examination, validated measures of cognitive dysfunction, depression, and global psychopathology, functional variables relevant to need for nursing home care, and selected mental health services indicators. RESULTS: Fewer than 10% of all nursing home residents were referred for psychiatric evaluation. A primary mental illness, evenly divided between psychoses and mood disorders, was found in 60% of the sample, and a psychiatric disorder associated with dementia or mental retardation was found in 25%. Six percent had complex neuropsychiatric features defying classification, and 4% had no mental disorder. Other disorders, such as substance abuse, were rare. Cognitive impairment and global psychopathology were prevalent in all diagnostic groups, and depressive symptoms were common even in patients without affective diagnoses. Eighty-eight percent of the sample were appropriately placed, based on their needs for daily care. Fifty-five percent had unmet mental health services needs. CONCLUSIONS: The PASARR referral process detected a group of seriously mentally ill, functionally disabled patients, most of whom required the level of care that nursing homes provide. Depressed and psychiatrically impaired dementia patients were underrepresented in the referral pool as measured against widely accepted prevalence figures for mental disorders in nursing home populations. The PASARR process as currently configured appears to be most efficient in identifying schizophrenic patients, who represent a small minority of nursing home residents, and the skewed sample it generates fails to provide an adequate basis for estimating overall mental health services needed in nursing homes. The PASARR process should be altered to improve referral rates for depressed and behaviorally disturbed dementia patients.
