Insight, symptoms and neurocognition in bipolar I patients.

BACKGROUND: Level of insight and its relationship to clinical variables and neurocognitive functions was assessed in bipolar I patients. METHODS: Verbal memory, executive functioning, sustained attention, general intelligence and other neurocognitive functions were compared between 37 chronic in- and outpatients and 31 matched normal controls. Detailed psychiatric interviews were completed to define the level of symptomatology and psychosocial functioning. Insight was assessed by the Scale to Assess Unawareness of Mental Disorder (SUMD). RESULTS: Seventy percent of the patients were classified as having impaired insight. Prevalence of impaired insight was 47% and 94% in remitted and symptomatic patients, respectively. Symptomatic patients scored significantly below remitted patients on insight and neurocognition. Illness and symptom unawareness were related to overall level of symptoms, measures of memory, conceptual ability and right hand psychomotor speed and accuracy. Misattribution of symptoms and signs was correlated to visuomotor speed and visuospatial performance in addition to affective symptoms and thought disturbance. CONCLUSIONS: Our findings support the hypothesis that impaired insight and other neurocognitive dysfunctions were present in a large percentage of cases among symptomatic as well as remitted bipolar patients. This may be of clinical relevance and raises important questions about the course and outcome of the illness.

Drug addiction in hepatitis C patients leads to a lower quality of life.

The subjective health status of hepatitis C patients has been relatively poorly studied. By using the Short Form 36 (SF-36), health-related quality of life (HRQOL) was assessed in a group of 42 hepatitis C patients. In all nine scales examined, the scores were generally low, and present drug use and being single were associated with especially large reductions in HRQOL. Compared with the Norwegian norms, scores were lower across all nine scales and significantly lower in eight. The study showed that the hepatitis C patients had definite reductions in HRQOL, but the impairment could not be fully explained by their hepatitis. Different non-viral factors such as drug use and marital status significantly influenced the results. This underlines the importance of taking other factors into account when studying the health status of hepatitis C patients.

Patient satisfaction and treatment environment: a 20-year follow-up study from an acute psychiatric ward.

The aim of this study was to examine to what extent the different subscales of the Ward Atmosphere Scale (WAS) are related to patient satisfaction on wards for psychotic patients. We wanted to examine if it was possible to replicate previous findings from cross-sectional studies and improve the understanding of which of the WAS subscales that should be considered the most important for patient satisfaction. From 1981 through 2000, the ward atmosphere, in an acute psychiatric ward, was evaluated 11 times with the Ward Atmosphere Scale (WAS). A total of 129 patients completed the WAS as well as a General Satisfaction Index (GSI) comprising three items. Z-scores were calculated to describe the fluctuations in the GSI and the WAS subscales. Four of the WAS subscales, Involvement, Practical orientation, Angry and aggressive behavior and Staff control, strongly co-varied with patient satisfaction. Unexpectedly, the Support and Order and organization subscales correlated only moderately with patient satisfaction. The remaining five WAS subscales (Spontaneous behavior, Autonomy, Personal problem orientation, Program clarity and Staff attitude to expressed feelings) were only weakly correlated with patient satisfaction. This study confirms that four of the six assumedly most important WAS subscales are strongly related to patient satisfaction on wards for psychotic patients. Changes in these WAS subscales seems to be paralleled by changes in patient satisfaction in the expected direction.

Measuring quality of life in first-episode psychosis.

Quality of life (QoL) measures are increasingly recognized as necessary parts of outcome assessments in psychosis. The present paper is a comprehensive study of patients with first-episode psychosis where QoL is measured by the commonly used Lehman Quality of Life Interview (L-QoLI). The aim is to examine if the L-QoLI maintain its original structure when used in a group of patients with first-episode psychosis, and to investigate what determines global subjective QoL with a specific emphasis on premorbid adjustment, duration of untreated psychosis (DUP) and clinical symptoms. The study indicates that the psychometric properties of the L-QoLI do not change significantly when used in first-episode samples. The patients report subjective and objective QoL in the fair to good range, with only a moderate association between the objective and subjective measures. Poor global satisfaction is predicted by being single, abusing drugs, being depressed, having a diagnosis of psychotic affective disorder, having poor premorbid social adjustment and DUP over 10 weeks. The study supports the notion that patients with first-episode psychosis construct QoL in the same way as other groups, and that longer durations of compromised function at this stage produces poor satisfaction with life rather than a downward readjustment of expectations.

Reducing the duration of untreated first-episode psychosis -- effects on baseline social functioning and quality of life.

OBJECTIVE: Long duration of untreated psychosis (DUP) is associated with poorer outcome. The TIPS study demonstrated that DUP can be reduced through early detection (ED). As quality of life (QoL) is associated with DUP it is expected that reduction of DUP leads to better QoL. METHOD: Consecutive first-episode patients with a DSM-IV diagnosis of non-organic, non-affective psychosis were included, 281 patients gave informed consent and 263 completed a full evaluation of QoL. RESULTS: There were no differences in subjective QoL between ED and No-ED groups attributable to reduction in DUP. There were significant bivariate differences in frequency of family and social contacts in favor of the ED group, but multivariate analyses indicated that these differences were based on differences in sample characteristics. CONCLUSION: Deterioration in QoL may precede overt symptom formation. Focus on functional loss in ED educational campaigns may identify risk subjects earlier in the course of the disorder.

Long-acting risperidone in stable patients with schizoaffective disorder.

Oral and long-acting risperidone has been shown to be effective for acute and maintenance treatment of patients with schizoaffective disorders. The present analysis investigated the efficacy and tolerability of direct transition from other antipsychotics to risperidone long-acting injectable in patients with schizoaffective disorder. Patients aged > or = 18 years with schizoaffective disorder (DSM-IV), who required a change of medication, received risperidone long-acting injectable 25 mg (increased to 37.5 or 50 mg, if necessary) every 2 weeks for 6 months. The analysis included 249 patients (47% male; mean age 43 years), of whom 74% completed the 6-month study. Mean scores for the total Positive and Negative Syndrome Scale (PANSS) and all three subscales were significantly reduced from baseline to week 4 (p < 0.001), with further improvements until treatment endpoint. Significant improvements from baseline to endpoint were seen in the mood symptom domains of anxiety/depression (10.4+/-4.1 vs 8.7+/-3.9) and uncontrolled hostility/excitement (7.6+/-3.6 vs 6.9+/-3.8). Mean Global Assessment of Function (GAF) score improved significantly from 59.4+/-15.6 at baseline to 66.4+/-17.7 (p < 0.001) at endpoint. Of 87 patients hospitalized at baseline, 67% were discharged at endpoint. Both quality of life (SF-36) and satisfaction with treatment were improved significantly at endpoint. Total ESRS scores fell progressively throughout the study, and the reduction was already statistically significant (p < 0.001) at 4 weeks. Small but statistically significant (p < 0.001) mean shifts of 1.8% were seen in body weight and Body Mass Index (BMI). Patients with schizoaffective disorder derived several benefits from a change to risperidone long-acting injectable, including reductions in psychiatric symptoms (particularly the mood symptom domains) and a reduction in the severity of drug-induced neurological movement disorders.

Depression during pregnancy and after delivery: a repeated measurement study.

The aim of this study was to examine the risk of depression in the postpartum period (first four months after delivery) as compared to the remaining postnatal year and the pregnancy period. All postpartum women from two municipalities in Norway were included in a questionnaire study of mental health (n = 416). Over 50% of the women (n = 259) answered an identical questionnaire at an additional time either before or after the postpartum period. The level of depression was measured by the Edinburgh Postnatal Depression Scale (EPDS) and the Hopkins Symptom Check List-25 items (SCL-25). The point prevalence of depression (EPDS> or =10) in the first four months postpartum did not differ significantly as compared to other time periods during pregnancy and the postnatal year. This finding remained also after controlling for other risk factors of depression; high score on the life event scale, prior depression and poor partner relationship. There was a non-significant trend of lower prevalence of depression during early pregnancy and after the first eight postnatal months. In conclusion, our findings suggest that the first four months postpartum were not distinguished by higher depression prevalence as compared to other time periods during pregnancy and the first postnatal year.

Does duration of untreated psychosis bias study samples of first-episode psychosis?

OBJECTIVE: While findings are contradictory, many studies report that long Duration of Untreated Psychosis (DUP) correlates with poorer outcome in first episode psychosis. In an outcome study of first-episode psychosis, we compared the patients who refused to participate in a follow-along with those who consented to estimate the importance of this factor in sample recruitment bias. Our questions were: (i) What is the percentage of refusers? (ii) Are there systematic differences between refusers and consenters on DUP and/or other admission variables? (iii) What is the risk of refusal for different values of DUP? METHOD: In an unselected group of consecutively admitted patients we compared follow-along refusers and consenters on the following admission variables: sex, age, diagnostic group, substance abuse, being in-patient, coming from an early detection site and DUP. We conducted a logistic regression analysis with refusal as the outcome variable. RESULTS: Ninety-three of 397 patients (23%) were refusers. In univariate analyses the only significant difference was found for DUP. The median DUP for consenters was 10 weeks and for refusers 32 weeks. DUP remained significant when all independent variables were controlled for. CONCLUSION: DUP was significantly related to risk for refusal. For tests of the impact of DUP on outcome, this may introduce a type II error bias.

Sex-sensitive cognitive performance in untreated patients with early onset gender identity disorder.

BACKGROUND: We explored whether the cognitive performance of gender identity disorder patients (GID) was comparable to that of their biological sex or skewed towards that of their gender identity. METHOD: We tested four potentially sex-sensitive cognitive factors (rotation, visualization, perception, and verbalization) as well as two neutral factors (logic and arithmetic) in GID patients from Norway (GID-N, n = 33) or the USA (GID-US, n = 19) and in a control group (C, n = 29). The testing was undertaken prior to cross sex hormone treatment. Four-way ANOVA was applied in the final analysis of the cognitive performance and its dependency on different predictors (age, biological sex, education, group). RESULTS: In both GID groups as well as in the control group (C) males excelled in visualization and rotation, also when controlling for potential confounders (biological sex, group, age and education). No female advantage was detected. Furthermore, no interaction between biological sex and group assignment was revealed in the samples. CONCLUSION: In this study the cognitive pattern of GID patients is consistent with that of their biological sex and not that of their gender identity.

Methodological pitfalls in early detection studies - the NAPE Lecture 2002. Nordic Association for Psychiatric Epidemiology.

OBJECTIVE: To identify and discuss methodological pitfalls that may help explain why many questions around early detection (ED) and duration of untreated psychosis (DUP) are still unsolved. METHOD: This paper concentrates on pitfalls in the following areas: sampling, measurement and data analyses. RESULTS: The main problems seem to be: SAMPLING: Referral bias, exclusion of patients, patient refusal, and patients lost to follow-up. MEASUREMENT: Reliability, which is particularly cogent for multisite investigations, and validity, which includes: Start of illness, start of psychosis, diagnoses, start of treatment, the relationship between ED and DUP and choice of outcome measures. Data Analyses: Overlooking threshold effects of DUP, improper control for baseline scores, and lack of control for confounders. CONCLUSION: Methodological pitfalls may bias ED studies. Several pitfalls are unavoidable, but proper design and quality assurance can reduce their impact. Researchers ought to identify the pitfalls, and to estimate and discuss their influence.

Depression in postpartum and non-postpartum women: prevalence and risk factors.

OBJECTIVE: The aim of the study was to assess the prevalence of depression in postpartum women as compared with non-postpartum women, and to identify risk factors of depression in both groups. METHOD: A population based questionnaire study was performed among women 18-40 years in two municipalities in Norway in 1998-1999. A total of 2,730 women were included, of whom 416 were in the postpartum period. RESULTS: The prevalence of depression was higher in non-postpartum as compared with postpartum women. High scores on the life event scale, a history of depression and a poor relationship to the partner were associated with depression in both postpartum and non-postpartum women. When controlling for the identified risk factors of depression the odds-ratio for depression in the postpartum period was 1.6 (95% CI: 1.0-2.6). CONCLUSION: The risk for depression was increased in the postpartum period, when controlling for the uneven distribution of risk factors.

Early detection strategies for untreated first-episode psychosis.

Some studies in first-episode schizophrenia correlate shorter duration of untreated psychosis (DUP) with better prognosis, suggesting that timing of treatment may be important. A three-site prospective clinical trial in Norway and Denmark is underway to investigate the effect of the timing of treatment in first-episode psychosis. One health care sector (Rogaland, Norway) is experimental and has developed an early detection (ED) system to reduce DUP. Two other sectors (Ullevål, Norway, and Roskilde, Denmark) are comparison sectors and rely on existing detection and referral systems for first-episode cases. The study ultimately will compare early detected with usual detected patients. This paper describes the study's major independent intervention variable, i.e. a comprehensive education and detection system to change DUP in first onset psychosis. System variables and first results from the four-year inclusion period (1997-2000) are described. It includes targeted information towards the general public, health professionals and schools, and ED teams to recruit appropriate patients into treatment as soon as possible. This plus easy access to psychiatric services via ED teams systematically changed referral patterns of first-episode schizophrenia. DUP was reduced by 1.5 years (mean) from before the time the ED system was instituted (to 0.5 years). The ED strategies appear to be effective and to influence directly the community's help-seeking behaviour.

Reactive psychosis and other brief psychotic episodes.

Modern classification systems have ignored the reactive psychoses, and little has been published using this concept during the last years. Nevertheless, the term is of interest in clinical practice where its presence is dependent on clinical skills and empathy. It is also important for a general understanding of the development of psychosis. The delineation from other acute psychoses needs clarification. Studies on reliability and validity are promising, but need extension. Traditionally, the concept of reactive psychosis has hardly been used outside Scandinavia, and it is encouraging that interest in brief psychoses seems growing in other cultures as well.

Death rates and causes of death in cohorts of serum hepatitis patients followed up for more than 20 years.

A cohort of 214 drug addicts with serum hepatitis and a cohort of 193 hepatitis patients without drug addiction were examined in respect of death rates, causes of death and a number of risk factors for reduced survival. The death rate was significantly higher among the drug addicts than among non-addicts. The annual mortality rate was 1.5% in the drug addict group and 0.7% in the non-addict group. The highest relative risk of death was 860 for female drug addicts in age group 15-24 compared to females of the same age in the general population. The most prevalent cause of death in the drug addict group was drug overdose (53%), whereas in the other group 66% died from various somatic diseases. Hepatitis or complications of viral hepatitis played no role as cause of death among the drug addicts, and infections as a whole were also responsible for very few deaths. For male drug addicts, imprisonment before admission and leaving hospital without the doctors' permission were risk factors for early death.

Thrombosis associated with physical restraints.

OBJECTIVE: Physical restraint is controversial, but still frequently used in psychiatric units. We describe two cases of thromboembolic phenomena, one with a fatal outcome, in association with physical restraint. METHOD: The world literature on physical restraint and thrombosis was reviewed by undertaking a search of electronic databases. RESULTS: To our knowledge, we are the first to report thrombosis associated with physical restraint. CONCLUSION: Immobilization and trauma to the legs while restraining a patient are adequate explanations for the occurrence of thrombosis. Special attention should be paid to thrombosis when employing restraints in psychiatric wards. Further systematic research into physical restraints in psychiatry is clearly needed.

Early detection and intervention in first-episode schizophrenia: a critical review.

OBJECTIVE: To review the literature on early intervention in psychosis and to evaluate relevant studies. METHOD: Early intervention was defined as intervention in the prodromal phase (primary prevention) and intervention after the onset of psychosis, i.e. shortening of duration of untreated psychosis (DUP) (secondary prevention). RESULTS: We found few studies aimed at early intervention, but many papers discussing the idea at a more general level. We identified no studies that prove that intervention in the prodromal phase is possible without a high risk for treating false positives. We identified some studies aimed at reducing DUP, but the results are ambiguous and, until now, no follow-up data showing a positive effect on prognosis have been presented. CONCLUSION: Early intervention in psychosis is a difficult and important challenge for the psychiatric health services. At the time being reduction of DUP seems to be the most promising strategy. Intervention in the prodromal phase is more ethically and conceptually problematic.

Review of validation studies of the Edinburgh Postnatal Depression Scale.

OBJECTIVE: To review validation studies of the Edinburgh Postnatal Depression Scale (EPDS). METHOD: A systematic search was performed in Medline and the Science Citation Index Expanded (ISI) from the period 1987-2000. For sensitivity and specificity of the EPDS presented in each study, 95% confidence intervals were estimated. Positive and negative predictive values were estimated assuming prevalences of postpartum depression ranging from 5% to 20%. RESULTS: Eighteen validation studies were identified. The study design varied between studies. The sensitivity and specificity estimates also varied: 65-100% and 49-100%, respectively. The confidence intervals were estimated to be wide. Our estimates suggest a lower positive predictive value in a normal population than in the validation study samples. CONCLUSION: Most studies show a high sensitivity of the EPDS. Because of the differences in study design and large confidence intervals, uncertainty remains regarding the comparability between the sensitivity and specificity estimates of the different EPDS versions.

The Edinburgh Postnatal Depression Scale: validation in a Norwegian community sample.

This study was undertaken to validate a Norwegian translation of the Edinburgh Postnatal Depression Scale (EPDS). The EPDS was validated against the DSM-IV criteria for major depression, derived from the PRIME-MD, in an interview study of 56 women selected from a community-based questionnaire study of 310 women 6 weeks postpartum. A score of > or =10 on the EPDS scale identified all women with major depression, giving a sensitivity of 100% (95% confidence interval; 72%-100%) and a specificity of 87% (95% confidence interval; 77%-95%). The EPDS scores were strongly correlated with the Montgomery-Asberg Depression Rating Scale in the subsample of women interviewed (n=56) and with the Hopkins Symptom Check List (SCL-25) scores in the questionnaire study (n=310). Our results with regard to the sensitivity and specificity estimates are comparable with prior validation studies; however, the confidence intervals around the estimates are wide. Nevertheless, this study confirms that the EPDS is a valid clinical screening instrument for detecting postpartum depression.
