Prevalence of metabolic syndrome among inpatients with schizophrenia

OBJECTIVE: Cardiovascular disease is one of the most prevalent factors responsible for excess mortality in schizophrenia. Metabolic syndrome (MetS) is associated with the development of coronary heart disease and diabetes mellitus. The aim in this cross-sectional study was to assess the prevalence of MetS in schizophrenic Turkish inpatients. METHOD: The study was conducted from January 2006 to June 2006, and included 231 patients with schizophrenia. All participants were enrolled from inpatients attending the Samsun Mental Health Hospital psychiatry clinic. All subjects were aged between 18 and 65 and met the DSM IV criteria for schizophrenia. MetS was taken as central obesity (defined as waist circumference: men > or = 94 cm, women > or = 80 cm) and meeting > or = 2 of the following abnormalities described by the International Diabetes Federation (IDF): a serum triglyceride level > 150 mg/dL, high-density lipoprotein (HDL) cholesterol < 40 mg/dL in men and < 50 mg/dL in women, blood pressure > or = 130/85 mm Hg, and a fasting serum glucose level > or = 100 mg/d/L. RESULTS: The study group consisted of 174 male and 57 female patients. Mean age was 38.5 +/- 10.5 and mean duration of illness was 15.76 +/- 9.95 years. The overall prevalence of MetS diagnosed according to the IDF criteria was 32.0% (n = 74) and was higher in females (61.4%) than in males (22.4%; p = 0.0001). In logistic regression analysis the last step of the regression model was gender (B = 1.70, p = 0.0001, OR = 5.50, 95% CI = 2.90-10.45). CONCLUSION: This study shows that the prevalence of MetS in Turkish patients with schizophrenia is similar to that of the general population, but lower than in other reports regarding the schizophrenia population.     

Body mass index among Japanese inpatients with schizophrenia

BACKGROUND: Many studies have emphasized the high frequency of obesity in schizophrenic patients. However, the characteristics of the Body Mass Index (BMI) distribution in Japanese schizophrenic patients remain unknown, and the aim of this study was to clarify these characteristics in a Japanese schizophrenic inpatient population. METHODS: The subjects were 273 inpatients (males: 141, females: 132) with schizophrenia. The patient BMI distribution was compared with normal control data obtained from the 2003 Japanese National Health and Nutrition Survey. RESULTS: The mean patient BMI was 23.0 +/- 4.3, and the BMI showed a normal distribution. The proportion of patients who were obese, of normal weight and underweight was 30.8%, 53.1%, and 16.1%, respectively. No statistical evidence of a higher frequency of obesity was found in male patients, compared to normal controls, but a higher frequency of underweight patients and a lower frequency of normal-weight patients were apparent in most decades of age. In female schizophrenia patients, a higher prevalence of obesity occurred in patients aged 50-59 years old, compared to controls. A higher rate of underweight elderly patients and a lower rate of normal-weight patients aged 40 to more than 70 years old were also apparent. CONCLUSIONS: The results suggest that not only obesity but also weight problems related to an underweight condition occur more frequently in Japanese schizophrenic inpatients than in normal controls. The deviation of the BMI distribution in Japanese schizophrenic inpatients may have a relationship with higher mortality and sudden death in schizophrenia.     

Association between feasibility of discharge, clinical state, and patient attitude among inpatients with schizophrenia in Japan

Aim:  There have been some studies on the feasibility of discharging mentally ill inpatients from mental hospitals. The purpose of the present study was to investigate how a psychiatrist judges whether an inpatient can be discharged.
Methods:  A survey regarding such judgments on discharge was conducted involving 549 inpatients with schizophrenia with a hospital stay of ≥1 year. Relationships between psychiatrist judgments on discharge and the Brief Psychiatric Rating Scale (BPRS), Scales for the Assessment of Negative Symptoms (SANS), Global Assessment Scale (GAS), patient attitude to discharge, and other variables were investigated. A similar analysis was conducted regarding patient attitudes toward discharge.
Results:  After controlling for potential confounding factors using multiple logistic regression, the judgments showed significant relationships with BPRS-P, SANS, GAS, and age. Patient attitudes showed significant relationships with the length of the current hospital stay, SANS, and psychiatrists' judgments.
Conclusion:  A psychiatrist's judgment regarding discharge is a comprehensive decision that takes into account psychiatric symptoms, social functioning, and age. Such a judgment could also affect a patient's own attitude toward discharge.     

Anxiety and substance use comorbidity among inpatients with schizophrenia

OBJECTIVE: To determine the association between lifetime anxiety symptoms and anxiety disorders and substance use disorders among patients with schizophrenia. METHOD: Participants were 184 inpatients with schizophrenia at the Schizophrenia Research Unit (SRU) at the New York State Psychiatric Institute (NYSPI). Multivariate logistic regression analyses were used to determine the relationship between specific anxiety symptoms and anxiety disorders and substance use disorders among inpatients with schizophrenia. RESULTS: Anxiety symptoms and anxiety disorders were prevalent among 31.5% of the sample. Panic attacks were associated with a significantly increased odds (OR=7.4 (1.2, 47.1)) of comorbid alcohol or substance use disorders (lifetime). This association was specific to panic attacks and persisted after adjusting for differences in sociodemographic characteristics and comorbid anxiety symptoms and anxiety disorders. CONCLUSIONS: These findings are consistent with and extend previous data by providing evidence of an association between panic attacks and increased likelihood of substance use disorders among inpatients with schizophrenia. Future studies that determine the nature of this relationship, the sequence of symptom onsets, and examine whether treatment of anxiety can influence the onset or outcome associated with substance use are needed.     

Predictors of compliance with neuroleptic medication among inpatients with schizophrenia: a discriminant function analysis.

OBJECTIVE: To identify clinically useful predictors of adherence to medication among persons with schizophrenia. METHOD: We evaluated levels of compliance with neuroleptic medication among 32 consecutive admissions with DSM-III-R schizophrenia from a geographically defined catchment area using a compliance interview. We also assessed symptomatology, insight, neurological status and memory. RESULTS: Less than 25% of consecutive admissions reported being fully compliant. Drug attitudes were the best predictor of regular compliance, symptomatology the best predictor of noncompliance, and memory the best predictor of partial compliance with neuroleptic medication. CONCLUSIONS: These data emphasise the complexity of factors that influence whether a person adheres to his medication regimen. Furthermore, they suggest that these factors may vary within the same person over time.     

Insight into illness and attitudes toward medications among inpatients with schizophrenia

This study assessed symptoms, severity of illness functional level, insight into illness, and attitudes toward medication in a sample of psychiatric patients who were newly admitted to a state hospital. The patients were evaluated before and after treatment with atypical, conventional, or mixed (atypical plus conventional) antipsychotic medication regimens with the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression, the Global Assessment of Functioning, the Scale to Assess Unawareness of Mental Disorder, and the Drug Attitude Inventory. Overall, the patients showed significant improvement in symptoms, severity of illness, functional level, and insight into their illness during the course of hospitalization. Their attitudes toward medications changed minimally during treatment. Only the patients who were treated with conventional antipsychotics showed significant improvement in their attitudes toward medication. However, the change was not large enough to differentiate the conventional antipsychotic treatment group from the other treatment groups.     

Competence to consent to research among long-stay inpatients with chronic schizophrenia

OBJECTIVE: Questions have been posed about the competence of persons with serious mental illness to consent to participate in clinical research. This study compared competence-related abilities of hospitalized persons with schizophrenia with those of a comparison sample of persons from the community who had never had a psychiatric hospitalization. METHODS: The study participants were administered the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), a structured instrument designed to aid in the assessment of competence to consent to clinical research. The scores of 27 persons who met DSM-IV criteria for schizophrenia who were long-stay patients on a state hospital research ward were compared with those of 24 individuals from the community who were of similar age, gender, race, and socioeconomic status. RESULTS: Significant differences were found between the patients and the community sample on three measures of competence-related abilities: understanding, reasoning, and appreciation. Degree of psychopathology and cognitive functioning were significantly negatively correlated with understanding and appreciation among the patients with schizophrenia. Length of hospitalization was significantly negatively correlated with all measures of decision-making capacities. CONCLUSIONS: The generally poor performance of the long-stay patients with chronic schizophrenia highlights the difficulties this group is likely to encounter in providing consent to research. However, variation across the sample points to the need for individualized assessment and for validated techniques for facilitating decision making in the face of decisional impairments.     

Suicidal ideation in inpatients with acute schizophrenia.

OBJECTIVE: Schizophrenia has been associated with a high rate of suicide. This study investigates the prevalence of suicidal ideation in a population of inpatients with acute schizophrenia, together with the clinical parameters associated with suicidal thoughts. METHOD: We assessed 93 schizophrenia patients. We matched subjects for age and sex and compared subjects with and without suicidal thoughts. We performed stepwise multiple regression analysis to assess the association between specific clinical symptoms and suicidal ideation. RESULTS: Of the patients, 20.4% reported suicidal thoughts during the last 15 days. Severity of depressive symptoms, motor retardation, guilt feelings, pathological guilt, and self-depreciation predicted the patients' suicidal ideation. CONCLUSIONS: Suicidal thoughts are frequent among inpatients with acute schizophrenia. Prevention of suicidal behaviour should include helping patients improve their self-esteem and reducing depression and guilt feelings.     

Substance use diagnoses and discharge patterns among psychiatric inpatients

Over a four-month period, 113 consecutive admissions to a general psychiatric ward of a Veterans Affairs hospital were evaluated for the presence of a substance use diagnosis as well as type of discharge (regular or irregular). Of the patients studied, 61 percent had a substance use diagnosis and 57 percent received an irregular discharge. Although there was some increase in the rate of irregular discharges among substance users, logistic regression analysis showed the increase was not significant. There was no difference between substance users and nonusers in length of stay. However, younger age and axis II pathology were associated with irregular discharge, and younger age was associated with shorter length of stay. Because an irregular discharge implies an undesirable treatment outcome, future studies should focus on identifying and providing optimal treatment of those patients at risk for irregular discharge.     

Predicting medication noncompliance after hospital discharge among patients with schizophrenia

OBJECTIVE: The study sought to identify predictors of noncompliance with medication in a cohort of patients with schizophrenia after discharge from acute hospitalization. METHODS: Adult psychiatric inpatients with schizophrenia or schizoaffective disorder for whom oral antipsychotics were prescribed (N=213) were evaluated at hospital discharge and three months later to assess medication compliance. Comparisons were made between patients who reported stopping their medications for one week or longer and patients who reported more continuous medication use. RESULTS: Of the 213 patients, about a fifth (19.2 percent) met the criterion for noncompliance. Medication noncompliance was significantly associated with an increased risk of rehospitalization, emergency room visits, homelessness, and symptom exacerbation. Compared with the compliant group, the noncompliant group was significantly more likely to have a history of medication noncompliance, substance abuse or dependence, and difficulty recognizing their own symptoms. Patients who became medication noncompliant were significantly less likely to have formed a good therapeutic alliance during hospitalization as measured by inpatient staff reports and were more likely to have family members who refused to become involved in their treatment. CONCLUSIONS: Patients with schizophrenia at high risk for medication noncompliance after acute hospitalization are characterized by a history of medication noncompliance, recent substance use, difficulty recognizing their own symptoms, a weak alliance with inpatient staff, and family who refuse to become involved in inpatient treatment.

Antipsychotic dosage at hospital discharge and outcomes among persons with schizophrenia

OBJECTIVE: Applying the schizophrenia treatment guidelines established by the Patient Outcomes Research Team (PORT) project, this study evaluated whether antipsychotic medication dosage influenced patient outcomes in routine clinical settings. METHODS: The associations between discharge antipsychotic medication dosage and short-term clinical, social, and service use outcomes were observed in a sample of 246 patients with schizophrenia or schizoaffective disorder. RESULTS: Patients who were given high dosages of antipsychotic medication at hospital discharge (more than 1,000 chlorpromazine milligram equivalents) had greater severity of symptoms three months after discharge than patients who were given guideline-recommended dosages (300 to 1,000 chlorpromazine milligram equivalents) (adjusted mean Brief Psychiatric Rating Scale scores of 45 and 39, respectively). Patients who were given low dosages of antipsychotic medication at hospital discharge (less than 300 chlorpromazine milligram equivalents) were less likely to report side effects (adjusted OR=.24) and slightly more likely to be nonadherent (21 percent of those within the recommended dose range compared with 39 percent of the those with low doses, not statistically significant after Bonferroni correction). No other differences related to medication dosage were observed in patient outcomes. CONCLUSIONS: Treatment that falls within antipsychotic medication dosage guidelines is associated with improvement in a limited, but critical, range of short-term patient outcomes in routine clinical settings.     

Privilege and discharge decisions for psychiatric inpatients with dysphagia.

Psychiatric patients have an increased risk for choking compared with the general population because of risk factors such as medication side effects and food gorging. A state hospital program for managing patients with dysphagia, or difficulty swallowing, includes interventions such as modified diets, mealtime monitoring, and adjusting psychotropic medications. Clinicians may find it difficult to make decisions about privileges and placement for dysphagic patients who do not comply with dietary modifications in unsupervised settings. For many such patients, close supervision and even placement on a locked ward may seem necessary. The authors recommend a risk-benefit approach: clinicians must balance the safety afforded by restrictions against the benefits of increased privileges or placement in a less restrictive setting. Quality of life and patients' preferences must also be considered.     

Violence in inpatients with schizophrenia: a prospective study.

Accurate evaluations of the dangers posed by psychiatric inpatients are necessary, although a number of studies have questioned the accuracy of violence prediction. In this prospective study, we evaluated several variables in the prediction of violence in 63 inpatients with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder. Nurses rated violent incidents with the Overt Aggression Scale. During hospitalization, sociodemographic variables, clinical history, neurological soft signs, community alcohol or drug abuse, and electroencephalographic abnormalities did not differ between violent and nonviolent groups. Violent patients had significantly more positive symptoms as measured by the Positive and Negative Syndrome Scale (PANSS), higher scores on the PANSS general psychopathology scale, and less insight in the different constructs assessed. A logistic regression was performed to discriminate between violent and nonviolent patients. Three variables entered the model: insight into symptoms, PANSS general psychopathology score, and violence in the previous week. The actuarial model correctly classified 84.13 percent of the sample; this result is significantly better than chance for the base rate of violence in this study. At hospital admission, clinical rather than sociodemographic variables were more predictive of violence. This finding has practical importance because clinical symptoms are amenable to therapeutic approaches. This study is the first to demonstrate that insight into psychotic symptoms is a predictor of violence in inpatients with schizophrenia.

Forecasting the number of inpatients with schizophrenia

There has been much discussion in Japan regarding the reduction of psychiatric beds. For effective healthcare planning, reliable forecasting is important. The purpose of this study was to predict the number of future schizophrenic inpatients using quantitative methodology. Data was obtained from a survey of schizophrenic inpatients conducted annually at the end of March by the Niigata Prefecture from 1974 to 2003. The numbers of schizophrenic inpatients in different age groups over a long period of time were used in a precise time-series analysis to establish trends. Then these past trends were used to forecast inpatient numbers for future years. The pattern of ascents and declines of each inpatient group stratified by age appeared to be duplicated by the next older age group 10 years later. The numbers of inpatients with schizophrenia in 2013 and 2023 are projected to be 78.5% and 56.7% of the number of patients in 2003, respectively. By 2033, the number is forecast to decline to 41.0% of the number in 2003. This study forecasts that inpatients with schizophrenia will decrease substantially over the next several decades. Policy should be designed to reflect this trend.     

Late-onset schizophrenia with epileptiform discharge

We report the case of a 51-year-old woman with no history of psychosis or epilepsy, presenting with abrupt late-onset psychosis with prominent epileptiform discharges with a diffuse sharp and slow wave complex. She had auditory and somatic hallucinations, delusions and loosening of associations, but epileptic seizures such as disturbance of consciousness and convulsion were not observed. Other laboratory studies, including CT, magnetic resonance imaging, single photon emission computed tomography, and cerebrospinal fluid were normal. The epileptiform discharge disappeared within 10 days after starting treatment with sodium valproate. Clinical improvement commenced after the EEG improvement, and was complete. The cause remains obscure, but it was suggested that there were some organic factors in the etiology of this late-onset psychosis. ( Int J Psych Clin Pract 2001; 5:67-70)
