ABSTRACTBackground:We aimed to assess whether there were any changes in the use of psychotropic drugs in Norwegian nursing homes between 2004 and 2011. Also, we investigated whether the predictors of use of specific psychotropic drug groups have changed.
We conducted a secondary analysis of two cohort studies of two Norwegian nursing home samples (2004/05 and 2010/11). Multivariate models were applied.
We found a significant decrease in the prescription of antipsychotic drugs between 2004 and 2011 (0.63 OR, 95%CI = 0.49-0.82, p
Information on who uses antipsychotic medication is limited to cross-sectional data. The objective of this study was to study the patterns of psychopathology at age 8?years and antipsychotic use between the ages of 12 and 25?years.
A total of 5525 subjects from the Finnish Nationwide 1981 birth cohort were linked to the National Prescription Register and the Hospital Discharge Register between 1994 and 2005. Information about parent-reported and teacher-reported conduct, hyperkinetic and emotional symptoms, and self-reported depressive symptoms was gathered at age 8?years. Information about antipsychotic use and about psychiatric disorders treated in hospitals between the ages of 12 and 25?years was register based. Diagnostic classes of hospital treatment included non-affective psychoses, affective disorders, and other psychiatric disorders.
The cumulative incidence of antipsychotic use by age 25?years was 2.8% among men (n?=?69) and 2.1% among women (n?=?55). In both sexes, living with other than two biological parents at age 8?years was associated with antipsychotic use, and three fourths of antipsychotic users had been treated for psychiatric disorders in a hospital. Among men, the most common hospital diagnosis was non-affective psychoses (44% of all antipsychotic users), and antipsychotic use was associated with childhood conduct problems. Among women, the most common hospital diagnosis was affective disorders (38% of all antipsychotic users), and antipsychotic use was associated with emotional problems and self-reported depressive symptoms in childhood.
Antipsychotic use in adolescence and young adulthood is different among men versus women both with regard to hospital diagnoses and childhood psychiatric problems.
To describe 1-year outcome in a large clinical epidemiologic sample of first-episode psychosis and its predictors.
A total of 301 patients with first-episode psychosis from four healthcare sectors in Norway and Denmark receiving common assessments and standardized treatment were evaluated at baseline, at 3 months, and at 1 year.
Substantial clinical and social improvements occurred within the first 3 months. At 1-year 66% were in remission, 11% in relapse, and 23% continuously psychotic. Female gender and better premorbid functioning were predictive of less severe negative symptoms. Shorter DUP was predictive for shorter time to remission, stable remission, less severe positive symptoms, and better social functioning. Female gender, better premorbid social functioning and more education also contributed to a better social functioning.
This first-episode sample, being well treated, may be typical of the early course of schizophrenia in contemporary centers.
OBJECTIVE: This study investigates the natural course of neuropsychiatric symptoms and the concomitant use of psychotropic medication among a large and representative sample of nursing-home patients with dementia. METHOD: The authors performed two data collections with structured interviews in a 1-year follow-up cohort-study including 26 nursing homes in four counties in two Norwegian health regions. The main outcome measures were baseline and follow-up frequencies, persistence and incidence of neuropsychiatric symptoms, and the change in neuropsychiatric symptoms with regard to the use of psychotropic medication. RESULTS: At baseline a representative sample of 1,163 nursing-home patients participated, of whom 933 had dementia. At the follow-up interview after 1 year, 633 of the patients who had dementia at baseline were assessed. Clinically significant neuropsychiatric symptoms were exhibited by 84% of patients with dementia at the baseline or follow-up interviews. Overall persistence of symptoms was 79%. Individual symptoms, such as depression (58%), delusions (56%), and agitation/aggression (47%) had resolved at a high rate. Persistent use of antidepressants (79%), antipsychotics (75%), or any psychotropic drug (88%) was common. There were no differences between users and nonusers of antipsychotics or antidepressants regarding the course of psychosis, agitation, or depression over the 1-year observation period. CONCLUSION: Neuropsychiatric symptoms are ubiquitous in nursing home patients with dementia. Overall the symptoms are chronically present, whereas individual symptoms often show an intermittent course. Long-term use of psychotropic medication is extensive. Uncertainty about treatment effects emphasizes the need for further treatment trials.
Non-adherence to antipsychotic medication and hospitalization in psychotic disorders are common and costly problems. Our aim was to identify risk factors for rehospitalization of patients with recent onset schizophrenia or schizoaffective disorder in a population-based cohort study. All patients with a first hospitalization for schizophrenia or schizoaffective disorder between 2006 and 2007 were included (n = 861). Patients were identified through and data retrieved from national Swedish health and population registers. We investigated how socio-demographic variables, duration of first hospitalization and prescription fills of antipsychotics were associated with rehospitalization in Cox regression models. A higher risk for rehospitalization within 28 days was observed in patients with a first hospitalization that was shorter than two weeks compared with patients who were hospitalized for more than four weeks: hazard ratio (HR) 2.30, 95% confidence interval (CI) 1.42 to 3.74. Further, patients who did not fill a prescription of antipsychotics within the first week after discharge had a higher risk of early rehospitalization than patients who were given antipsychotics (HR 1.75, 95% CI 1.13 to 2.72). More than 12 years of education was associated with a lower risk of early rehospitalization (HR 0.44, 95% CI 0.26 to 0.77). Sex, age, being born in Sweden, urban area residence and prescription fills of antipsychotics prior to first admission did not significantly affect the risk of early rehospitalization. In conclusion, we identified two potentially modifiable risk factors for rehospitalization: short duration of initial hospitalization and early non-adherence to medication.
175 cases of first episode psychosis were recruited to the Parachute project in 1996-97. The program offered highly available and continuous psychosocial support and a cautious use of antipsychotic medication for 5 years from inclusion. Outcome-data for year 13 after inclusion, were retrieved from Swedish population registries on 161 of the original cases. During the first year after inclusion the cohort improved in the scores of the Brief Psychiatric Rating Scale (BPRS) and Global Assessment of Function (GAF) to median levels that later remained rather stable. By month 12 the median GAF score was 65. 68% of the cases were in remission from psychotic symptoms as assessed with BPRS. 38% of the cases in remission and 60% not in remission had prescriptions of antipsychotic medication by month 12. By year 13 after inclusion, 42% were in employment and 55% had any dispensation of antipsychotic medication. 70% of the cases with employment had no dispensations of antipsychotic medication. In conclusion, Many first episode psychosis cases that were offered extensive psychosocial support and cautious use of antipsychotic medication had good early recovery and good late employment outcome.
Antipsychotics can induce in schizophrenic (SZ) and bipolar disorder (BP) patients serious body weight changes that increase risk for noncompliance to medication, and risk for cardiovascular diseases and diabetes. A genetic origin for this susceptibility to weight changes has been hypothesized because only a proportion of treated patients are affected, the degree of affection differing also in rates and magnitudes. In a first genome scan on obesity under antipsychotics in SZ and BP, we analyzed 21 multigenerational kindreds (508 family members) including several patients treated for a minimum of 3 years mainly with haloperidol or chlopromazine. Obesity was defined from medical files and was shown to be 2.5 times more frequent in patients treated with antipsychotics than in untreated family members (30 vs 12%). The nine pedigrees that showed at least two occurrences of obesity under antipsychotics were submitted to model-based linkage analyses. We observed a suggestive linkage with a multipoint Lod score (MLS) of 2.74 at 12q24. This linkage finding vanished when we used as phenotypes, obesity unrelated to antipsychotics, and when we used SZ or BP. This suggests that this positive linkage result with obesity is specific to the use of antipsychotics. A potential candidate gene for this linkage is the pro-melanin-concentrating hormone (PMCH) gene located at less then 1 cM of the linkage. PMCH encodes a neuropeptide involved in the control of food intake, energy expenditure, and in anxiety/depression. This first genome scan targeting the obesity side effect of antipsychotics identified 12q24 as a susceptibility region.
This study investigated the prevalence of schizophrenia (ICD-10 F 20) and of other non-affective psychosis (NAP, ICD-10 F 21 - F 29) in Sweden. It further assessed health care use, comorbidity and medication for these patient groups. Most studies either have a study population of patients with strictly defined schizophrenia or a psychosis population of which strict schizophrenia cases form a smaller set. The present study permits comparison of the two mutually exclusive patient groups using data at the individual level in the diagnosis of non-affective psychosis, use of health care, medical treatment and comorbidity by diagnosis or medical treatment.
In 2012, data were extracted from a regional registry containing patient-level data on consultations, hospitalisations, diagnoses and dispensed drugs for the total population in the region of Stockholm (2.1 million inhabitants). The size of the total psychosis population was 18,769, of which 7284 had a diagnosis of schizophrenia. Crude prevalence rates and risk rates with 95% confidence intervals were calculated.
In 2012, the prevalence of schizophrenia and NAP was 3.5/1000 and 5.5/1000, respectively. Schizophrenia was most common among patients aged 50-59 years and NAP most common among patients aged 40-49 years. Schizophrenia patients used psychiatric health care more often than the NAP patients but less overall inpatient care (78.6 vs. 60.0%). The most prevalent comorbidities were substance abuse/dependence (7.9% in the schizophrenia group vs. 11.7% in the NAP group), hypertension (7.9 vs. 9.7%) and diabetes (6.9 vs. 4.8%). The parenteral form of long-acting injectable antipsychotics was more often dispensed to patients with schizophrenia (10 vs. 2%).
This study, analysing all diagnoses recorded in a large health region, confirmed prevalence rates found in previous studies. Schizophrenia patients use more psychiatric and less overall inpatient health care than NAP patients. Differences between the two patient groups in comorbidity and drug treatment were found. The registered rates of a substance abuse/dependence diagnosis were the most common comorbidity observed among the patients investigated. The observed differences between the schizophrenia and the NAP patients in health care consumption, comorbidity and drug treatment are relevant and warrant further studies.
Antipsychotic drug use among children and adolescents is increasing, and there is growing concern about off-label use and adverse effects. The present study aims to investigate the incidence, psychiatric co-morbidity and pharmacological treatment of severe mental disorder in Norwegian children and adolescents.
We obtained data on mental disorders from the Norwegian Patient Registry on 0-18?year olds who during 2009-2011 were diagnosed for the first time with schizophrenia-like disorder (International Classification of Diseases, 10th revision codes F20-F29), bipolar disorder (F30-F31), or severe depressive episode with psychotic symptoms (F32.3 or F33.3). Data on filled prescriptions for psychotropic drugs were obtained from the Norwegian Prescription Database.
A total of 884 children and adolescents (25.1 per 100 000 person years) were first time diagnosed with schizophrenia-like disorder (12.6 per 100 000 person years), bipolar disorder (9.2 per 100 000 person years), or severe depressive episode with psychotic symptoms (3.3 per 100 000 person years) during 2009-2011. The most common co-morbid mental disorders were depressive (38.1%) and anxiety disorders (31.2%). Antipsychotic drugs were prescribed to 62.4% of the patients, 72.0% of the schizophrenia-like disorder patients, 51.7% of the bipolar disorder patients, and 55.4% of the patients with psychotic depression. The most commonly prescribed drugs were quetiapine (29.5%), aripiprazole (19.6%), olanzapine (17.3%), and risperidone (16.6%).
When a severe mental disorder was diagnosed in children and adolescents, the patient was usually also prescribed antipsychotic medication. Clinicians must be aware of the high prevalence of depressive and anxiety disorders among early psychosis patients.
BACKGROUND: Studies from the early 90s have suggested that patients selected for and compliant with treatment at specialized lithium clinics have lower-than-expected suicide rates. The present study examines whether such findings can be replicated under less select treatment conditions. METHOD: All 362 patients in Göteborg, Sweden, with DSM-III-R mood or schizoaffective disorders, hospitalized at least once during an 8-year period and treated with lithium for a minimum of 1 year, were followed. The study included 3911 patient-years on lithium and, because of permanent or temporary discontinuation, 1274 patient-years off lithium. RESULTS: The risk of suicide was significantly increased on (standard mortality ratio [SMR] = 6.1) as well as off lithium (SMR = 29.0), but the relative risk of suicide was 4.8 times higher during periods off lithium (p
