Studying inpatient treatment practices in schizophrenia: an integrated methodology

Education, ethnicity, and subjective life quality of recently discharged inpatients with schizophrenia

To inform psychiatric practice and research that enhances subjective quality of life (SQL) in diverse persons with schizophrenia, this study explored whether SQL differs in blacks and whites with varying educational attainment. Participants were interviewed upon discharge from 4 New York City psychiatric hospitals and after 3 months in community care (N = 264, mean age of 37 years, 61% male, 56% black). Linear regression equations predicted white and black SQL from educational attainment and control variables (ethnicity, age, functioning level, symptom severity). Educational accomplishment predicted lower SQL (F = 3.53, df = 4,227, p < 0.01), especially among whites (F = 5.87, df = 4,92, p < 0.001). However, the association was statistically insignificant in blacks who had SQL peaks and valleys with more years of school. Findings suggest that psychiatric care and research should account for educational and cultural variation in assessing and promoting SQL.

Therapeutic alliance, illness awareness, and number of hospitalizations for schizophrenia

While persons with multiple hospitalizations for schizophrenia have been found to differ from those with fewer, it remains unclear whether differences exist in illness awareness (personal understanding of psychopathology) or therapeutic alliance with inpatient staff (treatment involvement). This cross-sectional descriptive study therefore examined whether inpatients with more extensive hospitalization history 1) have less illness awareness and therapeutic alliance (perhaps contributing to the recidivism), 2) have more awareness and alliance (possibly because they have learned from experience), or 3) do not differ relative to persons with fewer inpatient stays. Results from staff and patient interviews (N=307) suggest that illness awareness is greater in persons with more hospitalizations, while therapeutic alliance appears to weaken. Individuals with greater recidivism may therefore need less help than others in building a self-knowledge of psychopathology that may already have developed. Instead, enhanced engagement in care may be more important after multiple disappointing relapses.

Practices preventing rehospitalization of individuals with schizophrenia

While psychosocial care approaches such as assertive community treatment or partial hospitalization can help prevent psychiatric inpatient stay, the ability of specific services to prevent admission is less clear (e.g., recognizing signs of impending relapse, promoting daily structure). Therefore, within 3 months of psychiatric hospital discharge, this study examined the extent to which inpatient readmission among 264 persons with schizophrenia was averted by interventions addressing medication education, symptom education, service continuity, social skills, daily living, daily structure, and family issues. After accounting for demographic characteristics in logistic regression equations, findings suggested that interventions addressing symptom education, service continuity, and daily structure were most effective in preventing inpatient stay among individuals with four or more prior hospitalizations. However, these services became statistically insignificant in preventing readmission among counterparts with fewer previous inpatient stays. While protective effects may differ among persons with varying hospitalization histories, results indicate that resource-poor outpatient centers could focus on these three interventions when care must be limited to rehospitalization prevention.

Determinants of care satisfaction among inpatients with schizophrenia

Satisfaction with inpatient psychiatry can promote positive treatment outcomes. Using information on 315 inpatients with schizophrenia, this study tested the hypothesis that some services promote more satisfaction than others. Relative to less satisfied counterparts, inpatients were more likely to approve of care if staff invested high levels of effort into education about: (1) control of symptoms with psychiatric medication, (2) adverse effects of stress on symptoms, and (3) social skills. Other services were appreciated less. In order to enhance intervention outcomes, the findings suggest that limited resources should be invested to a greater extent in practices that are valued most highly by patients.

Ethnicity and life quality of recently discharged inpatients with schizophrenia

Three months after inpatient discharge, quality of life was examined in 259 individuals with schizophrenia. As in findings by Lehman, Rachuba, and Postrado (1995), Black participants reported a higher quality than Whites after controlling for gender, degree of psychopathology, functioning level, substance abuse, and baseline life quality. Implications are discussed.

Incarceration and hospital care

Risk for jail or prison recidivism is well documented among incarcerated individuals with schizophrenia. However, it is less clear that risk is also high for psychiatric hospital readmission after accounting for mediating influences such as psychopathology severity, functioning level, substance misuse, and demographic characteristics. Relative to counterparts without prior time in jail, this study therefore assessed whether formerly incarcerated individuals with schizophrenia were more likely to repeatedly use hospital care after controlling for level of functioning and symptomatology. Among 315 inpatients, former inmates had a greater mean number of previous hospital stays than other patients (t = -2.13; df = 305; p = 0.03) and were more likely to visit the emergency room or be rehospitalized within 3 months of discharge (chi2 = 8.83; df = 1; p = 0.003). They were twice as likely to be readmitted, moreover, even after accounting in logistic regression for age, sex, race, global functioning, psychopathology severity, alcohol abuse or dependence, and drug abuse or dependence (OR = .49; CI = .26-.95). Implications for community care are discussed, and the suggestion is made that jail diversion programs should be renamed and refocused as "jail and hospital diversion."

Family involvement and satisfaction with community mental health care of individuals with schizophrenia

This longitudinal study of 246 individuals with schizophrenia examined family involvement and satisfaction with outpatient care after three months of psychiatric hospital discharge. Almost 10% of the individuals reported being dissatisfied with care. Controlling for demographic variables, individuals whose family members were not helped to cope with the mental illness had almost seven times the odds of being dissatisfied. Because care disapproval increases re-hospitalization risk (Druss, Rosenheek, & Stolar, 1999), suggestions are offered for how to facilitate kin coping.

Continuity of care in mental health services: toward clarifying the construct

OBJECTIVE

To clarify "continuity of care" (COC), a construct associated with the delivery of services for persons suffering from severe and persistent mental illness (SPMI), with attention to the service recipient's perception of COC.

METHOD

The study involved a systematic appraisal of the literature on COC, supplemented by interviews with 36 SPMI patients and their families. Statements highlighting attributes of COC were extracted from both sources.

RESULTS

Comments by patients and families corresponded to descriptions of COC in the mental health literature. Attribute classifications by independent teams of judges showed good consistency. The following 4 attribute domains of the COC construct were identified: service delivery, accessibility, relationship base, and individualized care.

CONCLUSIONS

Service recipients' perceptions of COC overlapped with representations of the construct in the mental health literature. The qualitative inquiry resulted in a draft, 47-item, self-report questionnaire for use in studies of interventions designed to facilitate COC.

Is the substance abuse of inpatients with schizophrenia overlooked?

The utility of medical records and clinician reports for assessing substance abuse among inpatients with schizophrenia or schizoaffective disorder was assessed in a sample of 296 patients recruited from four general hospitals in New York City. Measures derived from the medical record, the discharge summary, and primary clinician reports are compared to the results of a structured diagnostic interview. Analysis of the sensitivity, specificity, positive predictive value, and overall accuracy of the nondiagnostic sources found unexpectedly high levels of detection. Discharge summaries had the lowest sensitivity when compared to the diagnostic interview, raising concern that inpatient staff and clinicians may fail to communicate substance abuse problems to outpatient providers.

Recent HIV testing among general hospital inpatients with schizophrenia: findings from four New York City sites

BACKGROUND

While widely acknowledged to be an important clinical and public health issue, HIV assessment, counseling, and testing for the seriously mentally ill has not been well studied.

OBJECTIVE

To determine what proportion and which inpatients with schizophrenia have been recently tested for HIV.

METHOD

A sample of 300 inpatients with schizophrenia were recruited from four general hospitals in New York City over a one year period. After confirmation of diagnosis with a structured interview, and elicitation of sociodemographic and drug use information, medical record review identified recent HIV testing. Bivariate and multivariate analyses were used to identify subgroups more likely to be tested.

FINDINGS

Recent HIV testing had been performed for 17% of the sample and was concentrated among those with higher documented risks. The majority of patients remain untested even in groups with direct risks, such as injection drug use, and indirect risks, such as frequent cocaine use in last year. Some evidence was found that white patients at risk may be less likely to be tested than Hispanic or African American patients.

CONCLUSIONS

Aggressive efforts are needed to improve knowledge of HIV status among acutely ill patients with schizophrenia.

Assessing clinical predictions of early rehospitalization in schizophrenia

This study determines patient characteristics that predict early hospital readmission in schizophrenia and evaluates the extent to which inpatient staff accurately predict these readmissions. Adult inpatients with schizophrenia or schizoaffective disorder (N = 262) were evaluated at hospital discharge and 3 months later to assess hospital readmission. At hospital discharge, inpatient staff were asked to identify which patients were likely to be readmitted during this period. Comparisons were made between patients who were or were not readmitted and between readmitted patients who were or were not identified by staff as likely to be readmitted; 24.4% of the sample were readmitted within 3 months of hospital discharge. Early readmission was associated with four or more previous hospitalizations (85.7% vs. 57.7%, p = .004), comorbid substance use disorder (60.3% vs. 35.5%, p = .0006), major depression (40.6% vs. 26.8%, p = .04), absence of a family meeting with inpatient staff (58.2% vs. 41.8%, p = .02), and prescription of a conventional rather than an atypical antipsychotic medication (93.7% vs. 83.8%, p = .045). Twelve of the 63 readmitted patients were correctly predicted by staff to re-hospitalize. Staff tended to overestimate the risk of rehospitalization in patients with a poor therapeutic alliance, low global function, or initial involuntary admission and to underestimate the risk in patients with alcohol use disorders or four or more previous psychiatric hospitalizations. Early rehospitalization is common in schizophrenia and difficult to predict. Greater emphasis on comorbid alcohol use disorders and a history of multiple previous admissions may help clinicians identify patients at greatest risk for early rehospitalization.

Classifying psychiatric inpatients: seeking better measures

BACKGROUND

Use of case-mix reimbursement in psychiatric inpatients has been limited as a result of a lack of systems which effectively group patients according to required resource needs. In recognition of the fact that many patient factors, in addition to diagnosis influence delivery of care in psychiatry, new measures of patient need are emerging.

OBJECTIVE

This study compared improvement realized by using a multidimensional measure of patient severity, the Computerized Severity Index (CSI), to predict length of stay (LOS) in psychiatric inpatients over that achieved by using patient variables routinely collected in the discharge abstract.

METHOD

Through retrospective chart review, severity ratings were made on 355 psychiatric discharges with primary diagnoses of psychotic or major depressive disorders. Those ratings were combined with demographic and diagnostic data available in discharge abstracts and were then entered into multivariate regression analyses to model LOS.

RESULT

CSI ratings significantly contributed to prediction models, which accounted for an additional 9% to 11% of variation in LOS over discharge abstract data. Among patients with psychotic disorders, maximum severity during hospitalization was the best predictor of LOS, whereas among patients with depressive disorders, it was an increase in severity following admission.

CONCLUSION

Severity ratings, based on chart review, improved prediction of LOS over discharge abstract variables for psychiatric inpatients in two diagnostic groups. Further research is needed to estimate the impact of incorporating severity ratings into a grouping system for all psychiatric inpatients. Estimation of predictive accuracy is important to determine the amount of risk passed on to providers in a payment system based on psychiatric case mix.
