Substance use and symptoms of mental health disorders: a prospective cohort of patients with severe substance use disorders in Norway

BACKGROUND

There is high co-occurrence of substance use disorders (SUD) and mental health disorders. We aimed to assess impact of substance use patterns and sociodemographic factors on mental health distress using the ten-item Hopkins Symptom Checklist (SCL-10) over time.

METHODS

Nested prospective cohort study of 707 participants with severe SUD across nine opioid-agonist-therapy outpatient clinics and low-threshold municipality clinics in Norway, during 2017-2020. Descriptive statistics were derived at baseline and reported by means and standard deviation (SD). A linear mixed model analysis was used to assess the impact of substance use patterns and sociodemographic factors on SCL-10 sum score with beta coefficients with 95% confidence intervals (CI).

RESULTS

Mean (SD) SCL-10 score was 2.2 (0.8) at baseline with large variations across patients. We observed more symptoms of mental health disorders among people with frequent use of benzodiazepines (beta 3.6, CI:2.4;4.8), cannabis (1.3, CI:0.2;2.5), opioids (2.7, CI:1.1;4.2), and less symptoms among people using frequent stimulant use (- 2.7, CI:-4.1;-1.4) compared to no or less frequent use. Females (1.8, CI:0.7;3.0) and participants with debt worries (2.2, CI:1.1;3.3) and unstable living conditions (1.7, CI:0.0;3.3) had also higher burden of mental health symptoms. There were large individual variations in SCL-10 score from baseline to follow-up, but no consistent time trends indicating change over time for the whole group. 65% of the cohort had a mean score > 1.85, the standard reference score.

CONCLUSIONS

People with SUD have a considerable burden of mental health symptoms. We found no association between substance use patterns and change in mental health symptoms over time. This could suggest that the differences observed were indicating flattening of effects or self-medication to a larger degree than medication-related decline in mental health. This call for better individualized mental health assessment and patient care.

Disentangling Within- and Between-Person Effects During Response Inhibition in Obsessive-Compulsive Disorder

Background: Obsessive-compulsive disorder (OCD) has been related to worse performance, abnormal brain activity, and functional connectivity during response inhibition. Whether these findings are indications of stable traits that contribute to the development of the disorder, or whether they are a result of the state severity of obsessions and anxiety, remains unclear since previous research mainly has employed cross-sectional designs. The present study aimed to assess longitudinal between- and within-person relationships between symptoms, task performance, right inferior frontal gyrus brain activation, and connectivity between the right amygdala and the right pre-supplementary motor area in 29 OCD patients before and after concentrated exposure and response prevention treatment. Method: Patients received exposure and response prevention delivered during 4 consecutive days, following the Bergen 4-day Treatment format. Patients performed a Stop Signal Task during 3T functional Magnetic Resonance Imaging the day before treatment, as well as 1 week and 3 months after treatment completion. Multilevel models were used to analyze disaggregated within- and between-person effects over time. Independent variables were scores on the symptom severity scales for OCD, anxiety, depression, and state distress during scanning. Dependent variables were reaction time for go trials, stop signal response time, task-related brain activation and connectivity. Results: A positive between-person effect was found for obsessive-compulsive, anxiety, and depressive symptom severity on go trial reaction time, indicating that patients with higher symptom scores on average respond slower during accurate go trials. We also found no significant between- or within-person relations between symptom severity and task-related activation or fronto-limbic connectivity. Conclusions: The between-person findings may point toward a general association between slower processing speed and symptom severity in OCD. Longitudinal studies should disaggregate between- and within-person effects to better understand variation over time.

The Influence of Substance Use on Side Effects of Olanzapine, Quetiapine, Risperidone, and Ziprasidone in Psychosis

BACKGROUND

Side effects restrict the optimal use of antipsychotics. Little is known about the influence of substance use on side effects. The aim of this study was to compare antipsychotic side effects in patients with psychosis with and without substance use, while also taking medication history and diagnosis into consideration.

METHODS

All patients (n = 226, mean age 34, females 33%) diagnosed with schizophrenia spectrum disorders (SSD; F20-F29) or other psychosis (F30-F32; F10-F19), were treated with olanzapine, quetiapine, risperidone or ziprasidone, and were assessed at baseline, 4-weeks, 14-weeks, and 27-weeks. The UKU-Side Effects Self-Rating Scale version was used to evaluate the side effect profiles, and the information on substance use was based on the Clinician Drug Use Scale.

RESULTS

At baseline, 30% of the patients used substances, 54% were diagnosed with SSD, and 47% were antipsychotic naïve. The occurrence of side effects in total was not different in patients with substance use compared to without after 4-weeks of treatment, nor in the follow-up period. At 4-weeks there were some group differences in relation to substance use, diagnosis, and medication history for single side effects. Patients with substance use showed more increased dream activity, less reduced salivation, and more gynecomastia. Patients with SSD showed less neurological side effects, orgasm dysfunction, and tension/inner unrest. The medication naïve patients showed increased hypokinesia/akinesia.

CONCLUSION

Substance use alone does not influence the general magnitude of side effects of antipsychotic medication and does not indicate a different prescription practice in patients with psychosis and substance use.

Impact of clinical and sociodemographic factors on fatigue among patients with substance use disorder: a cohort study from Norway for the period 2016-2020

Background

The impact of clinical and sociodemographic factors on fatigue remains unknown among patients with substance use disorders (SUD). This study aims to evaluate fatigue among patients with SUD using a nine-item fatigue severity scale (FSS-9) and identify the impact that clinical and sociodemographic factors – such as injecting substance use, chronic infectious diseases, liver fibrosis, opioid agonist therapy (OAT), debt difficulties, and housing situation – have on fatigue.

Methods

We used data from a cohort of patients with SUD in Norway with annual health assessments surveying FSS-9 and some clinical and sociodemographic factors. A total of 915 FSS-9 measurements were collected from 654 patients during the period 2016–2020. We defined baseline as the first annual health assessment when the health assessments were listed chronologically. Time was defined as years from baseline. We used a linear mixed model to analyse whether the clinical and sociodemographic factors affected the FSS-9 sum score, presented with beta coefficients (β) with 95% confidence intervals (CI).

Results

The mean sum score of the FSS-9 was 43 (standard deviation: 16) at baseline. Females compared with males (adjusted mean difference of FSS-9 sum score: 4.1, 95% CI: 1.3–7.0), having debt difficulties compared with having no debt difficulties (2.9;0.4–5.3), and frequent use of benzodiazepines (5.7;3.0–8.4) or amphetamines (-5.0;-8.0– -2.0) compared to less frequent or no use of these substances changed the FSS-9 baseline sum score. The other clinical and sociodemographic factors did not predict any clinically relevant change in the FSS-9 sum score from baseline to the following health assessments.

Conclusion

Patients with SUD suffer from high levels of fatigue. Female patients, patients with debt difficulties, and those with extensive use of benzodiazepines are at particular risk of being fatigued. This should be taken into consideration when planning health services.

Comparative Effectiveness of Microdecompression Alone vs Decompression Plus Instrumented Fusion in Lumbar Degenerative Spondylolisthesis

IMPORTANCE

Conflicting evidence and large practice variation are present in the surgical treatment of degenerative spondylolisthesis. More than 90% of surgical procedures in the United States include instrumented fusion compared with 50% or less in other countries.

OBJECTIVE

To evaluate whether the effectiveness of microdecompression alone is noninferior to decompression with instrumented fusion in a real-world setting.

DESIGN, SETTING, AND PARTICIPANTS

This multicenter comparative effectiveness study with a noninferiority design assessed prospective data from the Norwegian Registry for Spine Surgery. From September 19, 2007, to December 21, 2015, 1376 patients at 35 Norwegian orthopedic and neurosurgical departments underwent surgery for lumbar spinal stenosis with degenerative spondylolisthesis without scoliosis. After excluding patients undergoing laminectomy alone, fusion without instrumentation, or surgery in more than 2 levels and those with a former operation at the index level, 794 patients were included in the analyses, regardless of missing or incomplete follow-up data, before propensity score matching. Data were analyzed from March 20 to October 30, 2018.

EXPOSURES

Microdecompression alone or decompression with instrumented fusion.

MAIN OUTCOMES AND MEASURES

A reduction from baseline of 30% or greater in the Oswestry Disability Index at 12-month follow-up.

RESULTS

After propensity score matching, 570 patients (413 female [72%]; mean [SD] age, 64.7 [9.5] years) were included for comparison, with 285 undergoing microdecompression (mean [SD] age, 64.6 [9.8] years; 205 female [72%]) and 285 undergoing decompression with instrumented fusion (mean [SD] age, 64.8 [9.2] years; 208 female [73%]). The proportion of each type of procedure varied between departments. However, changes in outcome scores varied within patients but not between departments. The proportion of patients with improvement in the Oswestry Disability Index of at least 30% was 150 of 219 (68%) in the microdecompression group and 155 of 215 (72%) in the instrumentation group. The 95% CI (-12% to 5%) for the difference of -4% was above the predefined margin of noninferiority (-15%). Microdecompression alone was associated with shorter operation time (mean [SD], 89 [44] vs 180 [65] minutes; P < .001) and shorter hospital stay (mean [SD], 2.5 [2.4] vs 6.4 [3.0] days; P < .001).

CONCLUSIONS AND RELEVANCE

Among patients with degenerative spondylolisthesis, the clinical effectiveness of microdecompression alone was noninferior to that of decompression with instrumented fusion. Microdecompression alone was also associated with shorter durations of surgery and hospital stay, supporting the suggestion that the less invasive procedure should be considered for most patients.

How can we improve specialist health services for children with multi-referrals? Parent reported experience

Background

Children with combined mental and somatic conditions pose a challenge to specialized health services. These cases are often characterized by multi-referrals, frequent use of health services, poor clinical and cost effectiveness, and a lack of coordination and consistency in the care. Reorganizing the health services offered to these children seems warranted. Patient reported experiences give important evidence for evaluating and developing health services. The aim of the present descriptive study was to explore how to improve specialist health services for children with multiple referrals for somatic and mental health conditions. Based on parent reported experiences of health services, we attempted to identify key areas of improvement.

Methods

As part of a larger, ongoing project; “Transitioning patients’ Trajectories”, we asked parents of children with multiple referrals to both somatic and mental health departments to provide their experiences with the services their children received. Parents/guardians of 250 children aged 6–12 years with multi-referrals to the Departments of Pediatrics and Child and Adolescent Mental Health at Haukeland University Hospital between 2013 and 2015 were invited. Their experience was collected through a 14 items questionnaire based on a generic questionnaire supplied with questions from parents and health personnel. Possible associations between overall experience and possible predictors were analyzed using bivariate regression.

Results

Of the 250 parents invited, 148 (59%) responded. Mean scores on single items ranged from 3.18 to 4.42 on a 1–5 scale, where five is the best possible experience. In the multiple regression model, perception of wait time (r = .56, CI = .44–.69 / β = 0.16, CI = .05–.28), accommodation of consultations (r = .71, CI = .62–.80 / β = 0.25, CI = .06–.45 / β = 0.27, CI = .09–.44), providing adequate information about the following treatment (r = .66, CI = .55–.77 / β = 0.26, CI = .09–.43), and collaboration between different departments at the hospital (r = .68, CI = .57–.78 / β = 0.20, CI = -.01–.40) were all statistically significantly associated with parents overall experience of care.

Conclusions

The study support tailored interdisciplinary innovations targeting wait time, accommodation of consultations, communication regarding the following treatment and collaboration within specialist health services for children with multi-referrals to somatic and mental specialist health care services.

Treatment of horizontal canal BPPV-a randomized sham-controlled trial comparing two therapeutic maneuvers of different speeds

OBJECTIVES

To compare the effect of a high-speed barbecue maneuver with the modified Lempert maneuver and sham in patients with benign paroxysmal positional vertigo (BPPV) of the horizontal canal.

METHODS

Randomized sham-controlled, single blinded multicenter clinical trial in two university hospitals investigating consecutive patients with horizontal canal BPPV.Patients were randomly assigned to high-speed barbecue (HSB), modified Lempert maneuver (ML), or sham maneuver (SM). All treatments were performed in a biaxial rotational chair with weekly follow-up to a maximum of three treatment sessions. The final follow-up was 3 months after the last treatment.

RESULTS

Primary outcome: 2-week recovery rate per protocol. Secondary outcome: Cumulative recovery rate and Dizziness Handicap Inventory (DHI) scores after 3 months per protocol (HSB and ML) and intention to treat (all groups).Fifty-four patients were analyzed after 2 weeks (HSB = 17; ML = 20; SM = 17). Two-week recovery rate was 14/17 after HSB, 11/20 after ML, and 4/17 after SM, with significantly better recovery in HSB [OR 15.17, 95% CI (1.85, 124.63), P = .001] using sham as base level. Recovery rate after 3 months was 15/17 after HSB and 15/19 after ML. Cumulative recovery rate showed no significant differences between the two treatment groups [95% CI (0.30, 13.14), P = .46] in cure rate DHI [95% CI (-16.56, 15.02), P = .92]. No unexpected adverse events were observed.

CONCLUSION

Velocity change in horizontal canal BPPV treatment gives a faster initial recovery. Rapid recovery could reduce the disease burden.

Pre-schoolers Referred to a Child and Adolescent Mental Health Clinic: A Hospital Quality Improvement Report

OBJECTIVE

Aim of the study was to evaluate the patient pathway from referral to assessment and diagnosis of pre-schoolers referred to a Child and Adolescent Mental Health Clinic (CAMHC) in Norway.

METHOD

Following data were collected retrospectively from medical records over a 2-year study period: data from clinical interviews for diagnostic evaluation, observation findings in kindergartens and the CAMHC, and results from medical examinations. The times taken from referral to first contact with the CAMHC, then to the first evaluation, and finally to diagnosis were assessed.

RESULTS

Of 13 402 pre-schoolers, 88 (0.7%) were referred to the CAMHC, of which 15 refused assessment and 69 completed a diagnostic assessment. Of the assessed children, 15 (21%) did not meet any criteria for an International Classification of Diseases, Tenth revision (ICD-10) diagnosis, 26 (38%) were diagnosed with developmental disorders, and 10 (14%) were given a non-specific diagnosis. For those children without a specific diagnosis, the mean time taken from referral to CAMHC assessment and diagnosis was longer, although not statistically significant, compared with those with a specific diagnosis (P = .52). No significant correlation between referral symptoms and final diagnosis was found.

CONCLUSIONS

Pre-schoolers referred to the CAMHC have an increased risk of having developmental disorders. Furthermore, 1 in 5 of the children had comorbidities. We propose more effective health care service by developing an interdisciplinary approach for the management of these children.

Elderly patients with no previous psychiatric history: suicidality and other factors relating to psychiatric acute admissions

BACKGROUND

The common recommendation that adults with onset of mental illness after the age of 65 should receive specialised psychogeriatric treatment is based on limited evidence.

AIMS

To compare factors related to psychiatric acute admission in older adults who have no previous psychiatric history (NPH) with that of those who have a previous psychiatric history (PPH).

METHOD

Cross-sectional cohort study of 918 patients aged ≥65 years consecutively admitted to a general adult psychiatric acute unit from 2005 to 2014.

RESULTS

Patients in the NPH group (n = 526) were significantly older than those in the PPH group (n = 391) (77.6 v. 70.9 years P < 0.001), more likely to be men, married or widowed and admitted involuntarily. Diagnostic prevalence in the NPH and PPH groups were 49.0% v. 8.4% (P < 0.001) for organic mental disorders, 14.6% v. 30.4% (P < 0.001) for psychotic disorders, 30.2% v. 55.5% (P < 0.001) for affective disorders and 20.7% v. 13.3% (P = 0.003) for somatic disorders. The NPH group scored significantly higher on the Health of the Nation Outcome Scale (HoNOS) items agitated behaviour; cognitive problems; physical illness or disability and problems with activities of daily living, whereas those in the PPH group scored significantly higher on depressed mood. Although the PPH group were more likely to report suicidal ideation, those in the NPH group were more likely to have made a suicide attempt before the admission.

CONCLUSIONS

Among psychiatric patients >65 years, the subgroup with NPH were characterised by more physical frailty, somatic comorbidity and functional and cognitive impairment as well as higher rates of preadmission suicide attempts. Admitting facilities should be appropriately suited to manage their needs.

Does childhood trauma influence cognitive functioning in schizophrenia? The association of childhood trauma and cognition in schizophrenia spectrum disorders

Childhood trauma (CT) is a risk factor for schizophrenia spectrum disorders (SSDs), and cognitive impairment is a core feature and a vulnerability marker of SSDs. Studies of the relationship between CT and cognitive impairment in SSDs are inconclusive. In addition, few studies have examined differential effects of CT subtypes, e.g. physical, sexual or emotional abuse/neglect, on cognitive functioning. The present study therefore aimed to examine the effects of CT and CT subtypes on cognitive impairment in SSD. Participants (n = 78) with SSDs completed a comprehensive neuropsychological test battery and the Childhood Trauma Questionnaire Short-Form (CTQ-SF). We compared global cognitive performance as well as scores in seven subdomains (verbal abilities, visuospatial abilities, learning, memory, attention/working memory, executive abilities and processing speed) between participants reporting no CT and those reporting CT experiences using independent samples t-tests as well as linear regression analyses to control for possible confounders. CT subtype physical neglect was associated with attention and working memory after controlling for positive and negative psychosis symptoms, years of education, antipsychotics, gender and age, and adjustment of multiple testing. Our results indicate that the observed heterogeneity in cognitive impairment in SSDs, especially attention/working memory abilities, may in part be associated with childhood physical neglect.

•

Research on childhood trauma and cognitive impairment in SSDs is inconclusive

•

Few studies investigated if CT subtypes (abuse and neglect) could explain the heterogeneity in cognitive impairment in SSDs

•

CT subtype physical neglect was associated with impairment in attention/working memory abilities

•

The observed heterogeneity in cognitive impairment in SSDs may in part be associated with CT subtypes

Violence rate dropped during a shift to individualized patient-oriented care in a high security forensic psychiatric ward

BACKGROUND

Contextual variables such as staff characteristics, treatment programs, assessment routines and administrative structures are found to influence patient violence rates in psychiatric forensic wards. The possible effects of current developments in treatment philosophy emphasizing patients' perspective and treatment involvement upon violence rate have not yet been examined. The aim of this paper is to analyse associations between such developments and the occurrence of violent incidents among patients in a high security forensic psychiatric ward.

METHODS

During a 17-year period with stable ward conditions, incidents of violence were systematically collected together with diagnostic, risk assessment and demographic patient characteristics. Changes in care- and organizational related variables such as nursing staff characteristics, treatment and management routines were collected. Multilevel modelling was applied to estimate the relationship between these variables and changes in violent incidents.

RESULTS

A substantial decline in the occurrence of violent incidents paralleled with changes in the ward during the middle phase of the study period. Most of the changes, such as implementation of new treatment and care routines and an increased proportion of female staff and higher education levels, were significantly related to a decrease in the occurrence of violent incidents in the ward.

CONCLUSIONS

Findings in this study suggest that an increase in individualized, patient-oriented care strategies, delivered by well-educated nursing staff with an equally balanced gender distribution contribute to a low level of violence.

Therapist Alliance-Building Behaviors, Alliance, and Outcomes in Cognitive Behavioral Treatment for Youth Anxiety Disorders

OBJECTIVE

The alliance influences outcomes in CBT for youth anxiety disorders. Thus, knowledge about how therapists can enhance the alliance is needed.

METHOD

Seventy-three youth with anxiety diagnoses (M age = 11.5 years, SD = 2.2; range 8 to 15 years; 47.9% boys; 90.4% white-European) participated in 10-session cognitive behavioral therapy in community clinics. Therapist alliance-building behaviors in session 2 was reliably coded with the observer-rated Adolescent Alliance-Building Behavior Scale (Revised) (AABS(R)). Alliance was measured as youth- and therapist-rated alliance, and youth-therapist alliance discrepancy in session 3. Outcomes were diagnostic recovery and anxiety symptom reduction at post-treatment and one-year follow-up, and treatment dropout. We examined the direct effects of alliance-building on alliance, alliance on outcomes, and alliance-building on outcomes in multilevel mediation models, and between- versus within-therapist variance across these effects.

RESULTS

The alliance-building behaviors collaborate, present treatment model, and explore motivation positively predicted alliance, whereas actively structuring the session (i.e., dominating) negatively predicted alliance. The alliance-building behaviors attend to experience, collaborate, explore motivation, praise, and support positively predicted outcomes. The alliance-building behaviors present treatment model, express positive expectations, explore cognitions, and support negatively predicted outcomes. The effect of collaborate on symptom reduction was mediated by youth-therapist alliance discrepancy. There was almost zero between-therapist variance in alliance-building, and considerable within-therapist variance.

CONCLUSION

Therapist alliance-building behaviors were directly (positively and negatively) associated with alliance and/or outcomes, with only one effect mediated by alliance. Alliance-building behaviors varied far more within therapists (i.e., across clients) than between therapists.

Different Trajectories of Prolonged Grief in Bereaved Family Members After Terror

Introduction: The loss of a loved one in a terror incident is associated with elevated risk for mental health disorders such as prolonged grief disorder (PGD) and posttraumatic stress disorder (PTSD), but the long- term adaptation after such losses are not well understood. This study aims to explore the trajectories of PGD among parents and siblings (n = 129) after the 2011 terror attack on Utøya Island, Norway. Methods: The 19-item Inventory of Complicated grief (ICG) was used to measure PGD at 18, 28, and 40 months post-loss. Latent class growth analysis (LCGA) was used to identify trajectories of grief and a multinomial regression analysis was conducted to examine predictors of class membership. Results: The analysis identified three grief trajectories; moderate/decreasing class (23%), high/slow decreasing class (64%), and a high/chronic class (13%). Predictors of high/slow recovery or chronic grief was female gender, previous depressive symptoms, and intrusion and avoidance symptoms. Conclusion: The findings highlights the difficult grief process and slow recovery that characterizes the majority of close family members bereaved by a terror-incident. Community mental health programs should strive for both early outreach and long-term follow-up after such incidents.

Psychosocial characteristics differentiate non-distressing and distressing voices in 10,346 adolescents

Adolescents hearing non-existent voices may be at risk for psychosis, but the prevalence of voice-hearing (VH) in the general population complicates clinical interpretations. Differentiating between VH with and without distress may aid treatment decisions in psychosis services, but understanding the differences between these two phenomena as they present in the normal adolescent population is necessary to validate this differentiation. The present study compared VH with and without distress in 10,346 adolescents in relation to clinical characteristics, known risk factors, predictors and psychosocial moderators of psychosis. A population-based cohort of Norwegian 16-19 years old adolescents completed a comprehensive web-based questionnaire, including two questions from the extended Launay-Slade Hallucinations Scale: (1) I often hear a voice speaking my thoughts aloud and (2) I have been troubled by hearing voices in my head. Adolescents reporting no VH, non-distressing VH or distressing VH were compared on 14 psychosocial and clinical variables. A multinomial regression model showed that non-disturbing voices were predicted by better school grades, social dysfunction, distractibility, affective symptoms and experience of trauma, while the disturbing voices were predicted by the experience of bullying and trauma, perceived negative self-worth and self-efficacy, less family support, dysregulation of activation, distractibility, self-harm and anxiety. Hearing voices without distress versus being distressed by the voices is related to different constellations of psychosocial variables, suggesting that they represent two separate groups of adolescents. The findings validate the emphasis on distress in clinical practice.

Relationships between depressive symptoms and panic disorder symptoms during guided internet-delivered cognitive behavior therapy for panic disorder

Aims: The current study explore the relationship between the trajectories of primary panic disorder symptoms and secondary depressive symptoms during guided internet-delivered cognitive behaviour therapy for panic disorder. Materials and methods: The patients (N=143) were recruited from an ongoing effectiveness study in secondary mental health outpatient services in Norway. Weekly self-reported primary panic disorder symptoms and secondary depressive symptoms were analysed. Results: primary panic disorder symptoms and secondary depressive symptoms improved significantly during the course of treatment, and at six months follow-up. Parallel process latent growth curve modelling showed that the trajectory of depressive symptoms and trajectory of panic disorder symptoms were significantly related. A supplementary analysis with cross-lagged panel modelling showed that (1) pre-treatment depressive symptoms predicted a positive effect of panic disorder symptoms early in treatment; (2) high early treatment panic disorder symptoms predicted low depressive symptoms at post-treatment. Conclusions: Guided ICBT for panic disorder is effective for both primary panic disorder symptoms and secondary depressive symptoms. Patients with high pre-treatment secondary depressive symptoms may constitute a vulnerable subgroup. A high level of panic disorder symptoms early in treatment seems beneficiary for depressive symptoms outcome. A time-dependent model may be necessary to describe the relationship between PAD symptoms and depressive symptoms during the course of treatment.

Predictors of treatment satisfaction in antipsychotic-naïve and previously medicated patients with acute-phase psychosis

Background: Treatment satisfaction predicts treatment adherence and long-term outcome for patients with psychosis. It is therefore important to understand the underpinnings of patient satisfaction in psychosis treatment for optimal treatment delivery. Aims: To examine the associations between satisfaction and level and change in positive symptoms, insight, depression and side effects of antipsychotics in previously medicated and antipsychotic-naïve patients. Method: Data derive from a randomised trial, with 226 respondents at baseline and 104 at follow-up. The measures were the positive subscale and insight item from the Positive and Negative Syndrome Scale, Calgary Depression Scale, the UKU Consumer Satisfaction Rating Scale, and the UKU side effects scale. Structural equation modelling was used to test the model. The full information maximum likelihood estimator used all available data. Results: In the sample of 226 patients, 67.3% were male and 44.2% were antipsychotic-naïve. The mean age was 34.1 years. For previously medicated patients, satisfaction was predicted by level of insight (b = -2.21, β = -0.42) and reduction in positive symptoms (b = -0.56, β = -0.39). For antipsychotic-naïve patients, satisfaction was predicted by level and change of insight (b = -2.21, β = -0.46), change in depression (b = -0.37, β = -0.26) and side effects (b = -0.15, β = -0.30). All predictors were significant at the 0.05 level. Conclusion: Reducing positive symptoms and side effects are important to enhance patient satisfaction. However, improving insight and reducing depression are more important in antipsychotic-naïve patients.

Supported accommodation for people with schizophrenia

Background: As a result of deinstitutionalization of psychiatric treatment and care, many people with severe mental illness have been offered supported accommodation. However, research on this costly intervention in Norway has been scarce. Aims: The aim of this study was to prospectively investigate the clinical and demographic factors associated with allocation to supported accommodation for people with schizophrenia. Methods: The study was a prospective cohort study of 334 people with schizophrenia acutely admitted to Haukeland University Hospital between 2005 and 2010. Information concerning allocation to supported accommodation in their residential municipalities was collected retrospectively. Univariate and multivariate statistical methods were used to assess the association of clinical and demographical variables with allocation to supported accommodation. Results: Supported accommodation was allocated to 29.6% of the participants during the study period. Age, gender, implementation of compulsory mental health care, substance abuse, symptom burden and suicidality were not associated with allocation to supported accommodation. Functional impairment, especially difficulties with activities of daily living, experiencing exacerbation in the course of chronic disease, being medicated and of Norwegian origin, favoured supported accommodation. Conclusions: Our results supported the hypothesis that people with severe mental illness presenting the greatest need for supported accommodation, based on functional difficulties and exacerbation of chronic disease were allocated supported accommodation. Symptom burden was not associated with allocation. Clinical implications: Further research is needed to examine the impact of supported accommodation on the outcomes for people with schizophrenia.

The influence of substance use on the effectiveness of antipsychotic medication: a prospective, pragmatic study

Background: Psychosis is associated with a high prevalence of substance use, leading to worsened prognosis. Less is known about how comorbid substance abuse may influence the effectiveness of antipsychotic medications. The aim of this study was to compare the effectiveness of second generation antipsychotics in patients with psychosis with and without substance use. Methods: All patients (n = 226) were aged >18 years old had symptom level scores of ≥4 on selected psychosis items on the Positive and Negative Syndrome Scale and met ICD-10 diagnostic criteria for psychosis. Information on substance use was collected based on the Clinician Drug Use Scale. Patients were grouped at baseline according to the presence of substance use, medication history and diagnosis group. Clinical symptoms at baseline and changes at follow-up were assessed with the PANSS. Results: At baseline about 30% of the patients used substances, most frequently cannabis followed by methamphetamine. About half (47%) of the patients had no prior exposure to antipsychotic medication at inclusion. Patients who had consumed substances showed no substantial differences in the PANSS score reduction as a result of antipsychotic medication compared to patients without substance. There were, however, some group differences in relation to pattern of change that were influenced by medication history. Substance use was found to be related to stronger reduction of positive symptoms from week 4 to week 27. Conclusion: Substance use alone did not influence antipsychotic effectiveness in this sample of patients with psychosis.

Follow-up score, change score or percentage change score for determining clinical important outcome following surgery? An observational study from the Norwegian registry for Spine surgery evaluating patient reported outcome measures in lumbar spinal stenosis and lumbar degenerative spondylolisthesis

Background

Assessment of outcomes for spinal surgeries is challenging, and an ideal measurement that reflects all aspects of importance for the patients does not exist. Oswestry Disability Index (ODI), EuroQol (EQ-5D) and Numeric Rating Scales (NRS) for leg pain and for back pain are commonly used patients reported outcome measurements (PROMs). Reporting the proportion of individuals with an outcome of clinical importance is recommended. Knowledge of the ability of PROMs to identify clearly improved patients is essential. The purpose of this study was to search cut-off criteria for PROMs that best reflect an improvement considered by the patients to be of clinical importance.

Methods

The Global Perceived Effect scale was utilized to evaluate a clinically important outcome 12 months after surgery. The cut-offs for the PROMs that most accurately distinguish those who reported ‘completely recovered’ or ‘much improved’ from those who reported ‘slightly improved’, unchanged’, ‘slightly worse’, ‘much worse’, or ‘worse than ever’ were estimated. For each PROM, we evaluated three candidate response parameters: the (raw) follow-up score, the (numerical) change score, and the percentage change score.

Results

We analysed 3859 patients with Lumbar Spinal Stenosis [(LSS); mean age 66; female gender 50%] and 617 patients with Lumbar Degenerative Spondylolisthesis [(LDS); mean age 67; 72% female gender]. The accuracy of identifying ‘completely recovered’ and ‘much better’ patients was generally high, but lower for EQ-5D than for the other PROMs. For all PROMs the accuracy was lower for the change score than for the follow-up score and the percentage change score, especially among patients with low and high PROM scores at baseline.

The optimal threshold for a clinically important outcome was ≤24 for ODI, ≥0.69 for EQ-5D, ≤3 for NRS leg pain, and ≤ 4 for NRS back pain, and, for the percentage change score, ≥30% for ODI, ≥40% for NRS leg pain, and ≥ 33% for NRS back pain. The estimated cut-offs were similar for LSS and for LDS.

Conclusion

For estimating a ‘success’ rate assessed by a PROM, we recommend using the follow-up score or the percentage change score. These scores reflected a clinically important outcome better than the change score.

Predictors of long-term outcome of CBT for youth with anxiety disorders treated in community clinics

Cognitive behavioral therapy (CBT) has proven long-term effects in youth with anxiety disorders. However, only a few studies have examined predictors of long-term outcomes of CBT treatment. The present study investigated possible predictors of long-term treatment outcomes in youth with mixed anxiety disorders treated in community mental health clinics. A total of 139 youth (mean age at assessment 15.5 years, range 11-21 years) with a principal diagnosis of separation anxiety disorder, social anxiety disorder, and/or generalized anxiety disorder were evaluated a mean of 3.9 years post-treatment (range 2.2-5.9 years). Outcomes were loss of all inclusion anxiety diagnoses, loss of the principal inclusion anxiety diagnosis, and changes in youth- and parent-rated youth anxiety symptoms. Predictors encompassed youth, parent and demographic factors, and post-treatment recovery. The most consistent finding was that low family social class predicted poorer outcomes. Higher treatment motivation was associated with better outcome whereas a diagnosis of social anxiety was associated with poorer outcome. Identified predictors extend on previous findings from efficacy trials, and the results indicate a need for more specific treatment protocols.

The effectiveness of guided internet-based cognitive behavioral therapy for social anxiety disorder in a routine care setting

Social anxiety disorder (SAD) is a common mental disorder with high persistence when untreated. As access to effective treatment is limited, guided internet-based cognitive behavioral therapy (ICBT) has been proposed as an effective alternative to face-to-face treatment. In this study, we examined the effectiveness of a 14-week therapist-guided ICBT program for patients with SAD undergoing routine care. From 2014 to 2017, 169 patients were included in the study, of which 145 started the treatment. The sample was all general practitioner-referred and had a lower educational level and higher rate of work absence compared to similar effectiveness studies. Regarding social anxiety symptoms, we identified significant within-group effect sizes (post-treatment: d = 1.00-1.10; six-month follow-up: d = 1.03-1.55). We also found significant effects on secondary depression symptoms (d = 0.67). Clinically significant improvement was reported by 66.2% of the participants, and 16.6% had a significant deterioration. Clinical implications of the current study are that guided ICBT for SAD is an effective treatment for the majority of the patients undergoing routine care. Future studies should explore interventions targeting non-responders and deteriorated patients.
