Intervention for reducing the overuse of upper endoscopy in patients <45 years: a protocol for a stepwise intervention programme.

Utilisation rates for healthcare services vary widely both within and between nations. Moreover, healthcare providers with insurance-based reimbursement systems observe an effect of social determinants of health on healthcare utilisation rates and outcomes. Even in countries with publicly funded universal healthcare such as Norway, utilisation rates for medical and surgical interventions vary between and within health regions and hospitals.Most interventions targeting overuse and high utilisation rates are based on the assumption that knowledge of areas of unwarranted variation in healthcare automatically will lead to a reduction in unwarranted variation. Recommendations regarding how to reduce this variation are often not very detailed or prominent.This paper describes a protocol for reducing the overuse of upper endoscopy in a Norwegian health region. The protocol uses a combination of digital tools and psychological methods targeting behavioural change in order to alter healthcare workers' approach to patient care.The aim of the planned intervention is to evaluate the effectiveness of a multifaceted set of interventions to reduce the overuse of upper endoscopy in patients under 45 years. A secondary aim is to evaluate the specific effect of the various parts of the intervention.

Reducing unwarranted variation: can a 'clinical dashboard' be helpful for hospital executive boards and top-level leaders?

BACKGROUND/AIM: In the past decades, there has been an increasing focus on defining, identifying and reducing unwarranted variation in clinical practice. There have been several attempts to monitor and reduce unwarranted variation, but the experience so far is that these initiatives have failed to reach their goals. In this article, we present the initial process of developing a safety, quality and utilisation rate dashboard ('clinical dashboard') based on a selection of data routinely reported to executive boards and top-level leaders in Norwegian specialist healthcare. METHODS: We used a modified version of Wennberg's categorisation of healthcare delivery to develop the dashboard, focusing on variation in (1) effective care and patient safety and (2) preference-sensitive and supply-sensitive care. RESULTS: Effective care and patient safety are monitored with outcome measures such as 30-day mortality after hospital admission and 5-year cancer survival, whereas utilisation rates for procedures selected on cost and volume are used to follow variations in preference-sensitive and supply-sensitive care. CONCLUSION: We argue that selecting quality indicators of patient safety, quality and utilisation rates and presenting them in a dashboard may help executive hospital boards and top-level leaders to focus on unwarranted variation.

Patient satisfaction and acute psychiatric inpatient treatment.

Background: Patient satisfaction (PS) with treatment is one of different outcome- and quality measures used by health care providers worldwide to improve service. We report from a study of patients admitted to the Department of Acute Psychiatry at the Oslo University Hospital where we investigated PS and difference between genders, days of hospital stay, diagnostic groups, voluntary-and involuntary admitted patients according to hospital records and perceived voluntary-and involuntary admittance.Materials and methods: All admitted patients during a 9-month period in 2014 were asked to participate by written consent. We used The Psychiatric Inpatient Questionnaire (PIPEQ), a self-report survey validated for assessment post-discharge. Analyses were conducted for a general dimension of PS and individual questions. A user representative was a part of the study from the beginning.Results: A total of 357 patients were asked and 256 consented. Results show that 68% were over all satisfied and 14% dissatisfied. Highest PS was found for cooperation with relatives and lowest for influence on choice of treatment and medication. We found no significant difference in PS between men and women, but patients with a personality disorder and with short stay were less satisfied. PS was significantly less for those perceiving involuntary admission regardless of legal status.Conclusion: The PIPEQ gives important input of patient's experience with the delivery of care. Answers range from very much satisfied to not at all depending on what was asked for. Exploring PS provides valuable information for quality improvements for different patient groups.

Reduced load-dependent default mode network deactivation across executive tasks in schizophrenia spectrum disorders.

BACKGROUND: Schizophrenia is associated with cognitive impairment and brain network dysconnectivity. Recent efforts have explored brain circuits underlying cognitive dysfunction in schizophrenia and documented altered activation of large-scale brain networks, including the task-positive network (TPN) and the task-negative default mode network (DMN) in response to cognitive demands. However, to what extent TPN and DMN dysfunction reflect overlapping mechanisms and are dependent on cognitive state remain to be determined. METHODS: In the current study, we investigated the recruitment of TPN and DMN using independent component analysis in patients with schizophrenia spectrum disorders (n = 29) and healthy controls (n = 21) during two different executive tasks probing planning/problem-solving and spatial working memory. RESULTS: We found reduced load-dependent DMN deactivation across tasks in patients compared to controls. Furthermore, we observed only moderate associations between the TPN and DMN activation across groups, implying that the two networks reflect partly independent mechanisms. Additionally, whereas TPN activation was associated with task performance in both tasks, no such associations were found for DMN. CONCLUSION: These results support a general load-dependent DMN dysfunction in schizophrenia spectrum disorder across two demanding executive tasks that is not merely an epiphenomenon of cognitive dysfunction.

Frontotemporal hypoactivity during a reality monitoring paradigm is associated with delusions in patients with schizophrenia spectrum disorders.

INTRODUCTION: Impaired monitoring of internally generated information has been proposed to be one component in the development and maintenance of delusions. The present study investigated the neural correlates underlying the monitoring processes and whether they were associated with delusions. METHODS: Twenty healthy controls and 19 patients with schizophrenia spectrum disorders were administrated a reality monitoring paradigm during functional magnetic resonance imaging. During encoding participants were instructed to associate a statement with either a presented (viewed condition) or an imagined picture (imagined condition). During the monitoring session in the scanner, participants were presented with old and new statements and their task was to identify whether a given statement was associated with the viewed condition, imagined condition, or if it was new. RESULTS: Patients showed significantly reduced accuracy in the imagined condition with performance negatively associated with degree of delusions. This was accompanied with reduced activity in the left dorsolateral prefrontal cortex and left hippocampus in the patient group. The severity of delusions was negatively correlated with the blood-oxygenation-level dependent response in the left hippocampus. CONCLUSIONS: The results suggest that weakened monitoring is associated with delusions in patients with schizophrenia spectrum disorder, and that this may be mediated by a frontotemporal dysfunction.

CACNA1C risk variant and amygdala activity in bipolar disorder, schizophrenia and healthy controls.

OBJECTIVES: Several genetic studies have implicated the CACNA1C SNP rs1006737 in bipolar disorder (BD) and schizophrenia (SZ) pathology. This polymorphism was recently found associated with increased amygdala activity in healthy controls and patients with BD. We performed a functional Magnetic Resonance Imaging (fMRI) study in a sample of BD and SZ cases and healthy controls to test for altered amygdala activity in carriers of the rs1006737 risk allele (AA/AG), and to investigate if there were differences across the diagnostic groups. METHODS: Rs1006737 was genotyped in 250 individuals (N = 66 BD, 61 SZ and 123 healthy controls), all of Northern European origin, who underwent an fMRI negative faces matching task. Statistical tests were performed with a model correcting for sex, age, diagnostic category and medication status in the total sample, and then in each diagnostic group. RESULTS: In the total sample, carriers of the risk allele had increased activation in the left amygdala. Group-wise analyses showed that this effect was significant in the BD group, but not in the other diagnostic groups. However, there was no significant interaction effect for the risk allele between BD and the other groups. CONCLUSIONS: These results indicate that CACNA1C SNP rs1006737 affects amygdala activity during emotional processing across all diagnostic groups. The current findings add to the growing body of knowledge of the pleiotropic effect of this polymorphism, and further support that ion channel dysregulation is involved in the underlying mechanisms of BD and SZ.

Severe social anxiety in early psychosis is associated with poor premorbid functioning, depression, and reduced quality of life.

OBJECTIVE: The main aim of the present study was to examine whether patients with first-episode psychosis (FEP) with severe social anxiety show poorer premorbid and current functioning, higher level of current clinical symptoms, and better "insight into illness." Furthermore, we wanted to explore whether social anxiety is associated with reduced quality of life (QoL). METHOD: A sample of 144 individuals with an FEP was divided into 3 groups depending on current level of social anxiety symptoms measured by the Liebowitz Social Anxiety Scale. Analysis of variance was performed including measures of demographic and clinical characteristics. A hierarchical regression analysis was performed to explore possible predictors of QoL. RESULTS: The most severe social anxiety group revealed poorer premorbid adjustment, lower social functioning, and higher levels of depression. Furthermore, this group revealed a higher awareness of illness and experienced reduced QoL. Overall, social anxiety was associated with reduced QoL even after adjusting for psychotic symptoms and depression. CONCLUSION: Severe social anxiety in FEP is associated with poor premorbid functioning and distinct clinical characteristics, besides being a possible predictor of QoL.

Arousal Modulates Activity in the Medial Temporal Lobe during a Short-Term Relational Memory Task.

This study investigated the effect of arousal on short-term relational memory and its underlying cortical network. Seventeen healthy participants performed a picture by location, short-term relational memory task using emotional pictures. Functional magnetic resonance imaging was used to measure the blood-oxygenation-level dependent signal relative to task. Subjects' own ratings of the pictures were used to obtain subjective arousal ratings. Subjective arousal was found to have a dose-dependent effect on activations in the prefrontal cortex, amygdala, hippocampus, and in higher order visual areas. Serial position analyses showed that high arousal trials produced a stronger primacy and recency effect than low arousal trials. The results indicate that short-term relational memory may be facilitated by arousal and that this may be modulated by a dose-response function in arousal-driven neuronal regions.

Children's eyewitness memory: a comparison of two interviewing strategies as realized by forensic professionals.

A critical issue for developmental psychology is how to obtain accurate and complete eyewitness memory reports from preschoolers without offering suggestions that might result in false allegations. We examined effects of two interviewing strategies (police/verbal interviews and clinician/prop-assisted interviews) on young children's reports about a medical examination. A total of 58 4-year-olds participated in the study, which conformed to a 2 (Interview Type)x2 (Number of Interviews) factorial design. Analyses revealed that interviewers spent less time off topic and asked more free recall questions in the police/verbal interviews than in the clinician/prop-assisted interviews. Compared with police/verbal interviews, clinician/prop-assisted interviews resulted in significantly more correct rejections and commission errors in children's memory reports. However, on a final free recall test, error rates were comparable across conditions. Higher child verbal intelligence predicted memory accuracy in police/verbal interviews, and greater parental attachment anxiety predicted children being asked a higher number of misleading questions. The study provides new insights into interview techniques that promote preschoolers' accurate eyewitness reports.
