Real-world effectiveness of long-acting injectable vs. oral antipsychotics in patients with bipolar I disorder: a 1-year retrospective observational study

Objective Long-acting injectable (LAI) antipsychotics are recommended in the treatment non-adherence. Despite the widespread use of LAI antipsychotics, there is limited data on clinical outcomes in bipolar I disorder (BD-I) patients with real-world data. We aimed to compare BD-I patients treated with LAI and oral antipsychotics (OAP) in terms of treatment effectiveness in a 1-year follow-up period. Methods The study was conducted retrospectively with electronic health records of 116 BDI patients. The primary outcomes were whether patients in the LAI group and the OAP group differed in relapse, rehospitalization, emergency room (ER) visits, and all-cause treatment discontinuation at 1-year follow-up after a mania episode. Cox regression modeling was used to predict the recurrence of any mood episode and all-cause treatment discontinuation during follow-up. The secondary outcomes evaluated were the effects of sociodemographic and clinical parameters and concomitant psychotropic medications on the course of the illness and treatment adherence. Results Of all 116 patients, 33 (28.4%) were under LAI, and 83 (71.6%) were under OAP treatment. LAI users had a history of more hospitalizations and total mood episodes. Patients in the LAI group had more treatment non-adherence before the index hospitalization. At 1-year follow-up, there was no difference between the groups in terms of any mood relapse, rehospitalization, ER visits, and all-cause treatment discontinuation. As a secondary outcome, lithium users were found to have fewer new episodes and discontinuations of treatments. Conclusions In real-world data, there is no evidence that LAI antipsychotics (compared to OAP) are superior in the maintenance treatment of BD. These results are important in terms of reflecting clinical practices for the treatment of BD-I. These results do not devalue the use of LAI therapy in BD; however, more studies are needed to identify positive predictors for LAI treatments in BD.

The influence of concomitant antidepressant and antipsychotic medication on antidepressant effect and seizure duration of electroconvulsive therapy.

A significant proportion of patients with a depressive disorder show resistance to pharmacological and psychotherapeutic antidepressant treatments. Electroconvulsive therapy (ECT) is still one of the most effective treatment methods, especially in the acute phase. In everyday clinical practice, this usually accompanies pharmacological treatment. It has been shown that pharmacological treatment following acute ECT treatment reduces the rate of relapses. However, the effect of various antidepressants (ADs) and antipsychotics (APs) on the effect during the course of ECT has rarely been investigated. In this retrospective chart review study, the data of 104 depressive patients treated with ECT were examined. We analyzed the influence of concomitant administration of AD and AP or no psychotropic medication on the effect of ECT using the Montgomery-Åsberg Depression Rating Scale (MADRS). We further analyzed the influence of the ADs Bupropion, Venlafaxine, and Sertraline or no AD and the influence of augmentation with Aripiprazole or Quetiapine or Olanzapine. Psychotropic medication did not have an impact on antidepressant efficacy of ECT as measured with the MADRS scores. In addition, the comparison between the antidepressant or antipsychotic medications themselves did not show any significant difference. However, we found a significantly different seizure duration depending on the antidepressant substance that patients received during ECT (p = .008). ECT treatment itself led to a highly significant reduction of 13.3 points in the MADRS (p <.001). Taken together, our study underlines that concomitant psychotropic medication while doing electroconvulsive therapy does not bare the risk of prolonged seizure duration or does it reduce the effectiveness of ECT. To the best of our knowledge, this study is the first to examine the effect of treatment with antidepressants in combination with antipsychotics while doing ECT. In light of our results, this combination therapy is safe and effective. Bearing in mind the delay in onset of antidepressant action of medication and the importance of antidepressant medication for relapse prevention, this study further supports the recommendation that psychotropic medication should be given in adjunction to ECT.

Association between benzodiazepine anxiolytic polypharmacy and concomitant psychotropic medications in Japan: a retrospective cross-sectional study.

Guidelines for various psychiatric disorders recommend short-term use of benzodiazepine anxiolytic monotherapy in few cases. Contrarily, benzodiazepine anxiolytic polypharmacy (BAP) is not recommended in any case. However, BAP is often used in real world. Therefore, this study aimed to determine the association between BAP and concomitant use of psychotropic medications. This retrospective cross-sectional study used claims data from the Japan Medical Data Center. Medical information of health insurance subscribers treated with benzodiazepine anxiolytics in June 2019 was extracted. Prescription of two or more benzodiazepine anxiolytics was defined as BAP. Binary logistic regression analysis was performed to investigate the factors associated with BAP, using age group, sex, type of subscriber, and number of concomitant hypnotics, antidepressants, and antipsychotics (none, one, and two or more) as covariates. The eligible participants were 104,796 adults who were prescribed benzodiazepine anxiolytics. Among them, 12.6% were prescribed two or more drugs. Logistic regression analysis revealed that BAP was significantly associated with those who received hypnotic monotherapy (adjusted odds ratio [aOR]: 1.04, 95% confidence interval [CI]: 1.001-1.09, p=0.04), antidepressant monotherapy and polypharmacy (aOR: 1.57, 95% CI: 1.51-1.63, p<0.001 and aOR: 1.98, 95% CI: 1.88-2.09, p<0.001, respectively), and antipsychotic monotherapy and polypharmacy (aOR: 1.12, 95% CI: 1.07-1.19, p<0.001 and aOR: 1.41, 95% CI: 1.30-1.54, p<0.001, respectively). Conversely, lower BAP was associated with those who received hypnotic polypharmacy (aOR: 0.86, 95% CI: 0.81-0.91, p<0.001). This study showed that the greater the number of concomitant antidepressants and antipsychotics, the greater the association with BAP. Since combination therapy with antidepressants or antipsychotics is generally not recommended, patients receiving combination therapy with these medications may be resistant to pharmacotherapy. Therefore, implementing the recommended non-pharmacological treatments may reduce BAP.

Clinical impact of reducing the frequency of clozapine monitoring: controlled mirror-image cohort study.

To minimise infection during COVID-19, the clozapine haematological monitoring interval was extended from 4-weekly to 12-weekly intervals in South London and Maudsley NHS Foundation Trust. To investigate the impact of this temporary policy change on clinical and safety outcomes. All patients who received clozapine treatment with extended (12-weekly) monitoring in a large London National Health Service trust were included in a 1-year mirror-image study. A comparison group was selected with standard monitoring. The proportion of participants with mild to severe neutropenia and the proportion of participants attending the emergency department for clozapine-induced severe neutropenia treatment during the follow-up period were compared. Psychiatric hospital admission rates, clozapine dose and concomitant psychotropic medication in the 1 year before and the 1 year after extended monitoring were compared. All-cause clozapine discontinuation at 1-year follow-up was examined. Of 569 participants, 459 received clozapine with extended monitoring and 110 controls continued as normal. The total person-years were 458 in the intervention group and 109 in the control group, with a median follow-up time of 1 year in both groups. During follow-up, two participants (0.4%) recorded mild to moderate neutropenia in the intervention group and one (0.9%) in the control group. There was no difference in the incidence of haematological events between the two groups (IRR = 0.48, 95% CI 0.02-28.15, P = 0.29). All neutropenia cases in the intervention group were mild, co-occurring during COVID-19 infection. The median number of admissions per patient during the pre-mirror period remained unchanged (0, IQR = 0) during the post-mirror period. There was one death in the control group, secondary to COVID-19 infection. There was no evidence that the incidence of severe neutropenia was increased in those receiving extended monitoring.

Sublingual dexmedetomidine: repurposing an anesthetic as an anti-agitation agent

ABSTRACT Introduction Especially when acutely ill, individuals with schizophrenia and bipolar disorder can present with agitated behavior. The initial approach to agitation management are non-pharmacologic strategies such as verbal de-escalation techniques; however, pharmacologic interventions may be needed. Dexmedetomidine is a selective alpha-2 adrenergic receptor agonist, and a sublingual formulation has been approved in the US for the treatment of agitation associated with schizophrenia and bipolar disorder in adults. Areas covered The authors review the published literature on sublingual dexmedetomidine using the US National Library of Medicine’s PubMed.gov resource. Pharmacodynamics, pharmacokinetics, and efficacy and tolerability findings are summarized. The authors also provide a discussion to its potential place in the treatment armamentarium. Expert opinion Sublingual dexmedetomidine is an effective and well-tolerated pharmacologic option for the treatment of agitation associated with schizophrenia and bipolar disorder. The sublingual method of administration allows for a rapid onset of action with treatment effects beginning as early as 20 minutes after administration. Adverse effects include somnolence, hypotension, oral paresthesia, hypoesthesia, and dry mouth. Further study will be needed to evaluate sublingual dexmedetomidine in real-world patients receiving concomitant psychotropic medications.

2.67 Incidence of Psychiatric Comorbidity and Concomitant Psychotropic Medication Use Among Individuals With Neurodevelopmental Disorders Presenting in Distress

Individuals with neurodevelopmental disorders experience an increased risk of developing mental health conditions. Insufficiently treated mental health conditions in this population frequently present with agitation and irritability. Sources of Distress (“Sources”) is an online branching logic questionnaire that aims to address this issue by querying parent and caregivers’ observations and knowledge about the affected individuals.

Concomitant medication use in children with autism spectrum disorder: Data from the Autism Biomarkers Consortium for Clinical Trials.

Children with autism spectrum disorder are prescribed a variety of medications that affect the central nervous system (psychotropic medications) to address behavior and mood. In clinical trials, individuals taking concomitant psychotropic medications often are excluded to maintain homogeneity of the sample and prevent contamination of biomarkers or clinical endpoints. However, this choice may significantly diminish the clinical representativeness of the sample. In a recent multisite study designed to identify biomarkers and behavioral endpoints for clinical trials (the Autism Biomarkers Consortium for Clinical Trials), school-age children with autism spectrum disorder were enrolled without excluding for medications, thus providing a unique opportunity to examine characteristics of psychotropic medication use in a research cohort and to guide future decisions on medication-related inclusion criteria. The aims of the current analysis were (1) to quantify the frequency and type of psychotropic medications reported in school-age children enrolled in the ABC-CT and (2) to examine behavioral features of children with autism spectrum disorder based on medication classes. Of the 280 children with autism spectrum disorder in the cohort, 42.5% were taking psychotropic medications, with polypharmacy in half of these children. The most commonly reported psychotropic medications included melatonin, stimulants, selective serotonin reuptake inhibitors, alpha agonists, and antipsychotics. Descriptive analysis showed that children taking antipsychotics displayed a trend toward greater overall impairment. Our findings suggest that exclusion of children taking concomitant psychotropic medications in trials could limit the clinical representativeness of the study population, perhaps even excluding children who may most benefit from new treatment options.

Medicinal cannabis in children and adolescents with autism spectrum disorder: A scoping review.

Autism spectrum disorder (ASD) is a neurodevelopmental condition estimated to affect 1 in 66 children in Canada and 1 in 270 individuals worldwide. As effective therapies for the management of ASD core and associated symptoms are limited, parents are increasingly turning to clinicians for advice regarding the use of medicinal cannabis to manage behavioural disturbances. The objective of this scoping review was to identify and map symptoms, outcomes and adverse events related to medicinal cannabis treatment for ASD-related behaviours. Ovid MEDLINE, Embase, CINAHL, PsycInfo, Web of Science Core Collection, Google Scholar and grey literature sources were searched up to 5 January 2020 for studies. Included studies met the following criteria: (1) investigate the use of medicinal cannabis, (2) at least 50% participants had ASD, (3) at least 50% of the study population was 0-18 years old and (4) any study design (published or unpublished). We identified eight completed and five ongoing studies meeting the inclusion criteria. All studies reported substantial behaviour and symptom improvement on medicinal cannabis, with 61% to 93% of subjects showing benefit. In the three studies reporting on concomitant psychotropic medication usage and with cannabis use, up to 80% of participants observed a reduction in concurrent medication use. Adverse events related to cannabis use were reported in up to 27% of participants related, and two participants had psychotic events. Early reports regarding medicinal cannabis in paediatric ASD symptom management are presented as positive; the evidence, however, is limited to very few retrospective cohort and observational studies. Evidence of safety and efficacy from prospective clinical trials is needed.

A phase 2a randomised, double-blind, placebo-controlled, parallel-group, add-on clinical trial of ebselen (SPI-1005) as a novel treatment for mania or hypomania

RationaleLithium is an effective prophylactic and anti-manic treatment in bipolar disorder; however, its use is declining through perceived poor tolerance and toxicity. Lithium inhibits inositol monophosphatase (IMPase), a probable key therapeutic mechanism. The anti-inflammatory drug, ebselen, also inhibits IMPase and appears well-tolerated and safe.ObjectivesTo assess the efficacy of adjunctive ebselen in mania using the Young Mania Rating Scale (YMRS) (primary outcome) and the Altman Self-Rating Mania (ASRM) Scale and Clinical Global Impression-Severity Scale (CGI-S) among the secondary outcomes.MethodsRandomised, double-blind, placebo-controlled, parallel-group trial conducted between October 2017 and June 2019, at Oxford Health NHS Foundation Trust. Pharmacy-controlled randomisation was computer-generated, with full allocation concealment. In/outpatients (n = 68) aged 18–70, experiencing mania or hypomania, were assigned to 3 weeks ebselen (600 mg bd) (n = 33) or placebo (n = 35). Participants received usual clinical care and psychotropic medication.ResultsEbselen was numerically, but not statistically, superior to placebo in lowering scores on the YMRS (adjusted mean difference and 95% confidence interval, − 1.71 (− 5.34 to 1.91), p = 0.35) and ASRM (− 1.36 (− 3.75 to 1.17), p = 0.29). However, scores on the CGI-S were significantly lower at week 3 in ebselen-treated participants (adjusted mean difference, − 0.58 (− 1.14 to − 0.03), p = 0.04). A post hoc analysis excluding patients taking concomitant valproate treatment magnified the difference between ebselen and placebo on the YMRS. Adverse events were comparable between groups, and mild.ConclusionsEbselen merits further investigation where concomitant psychotropic medication is better controlled and participants taking valproate are excluded. If effective, ebselen’s superior tolerance and safety could make it a useful alternative to lithium.Trial registrationTrial Registry: www.clinicaltrials.gov, Identifier: NCT03013400.

Medical Weight-Loss Outcomes in Patients Receiving Concomitant Psychotropic Medication: A Retrospective Cohort Study.

This study aimed to elucidate medical weight-loss outcomes in patients unexposed or exposed to psychotropic medication(s). This retrospective cohort study evaluated weight-loss outcomes of completers treated at an academic weight-management center between April 1, 2014, and April 1, 2016. Patients were classified as either unexposed (not prescribed psychotropic medication) or exposed (prescribed psychotropic medication) based on use of antidepressants, mood stabilizers, or antipsychotics during the study. Of 1,932 patients seen during the study period, 885 were eligible for inclusion, of whom 619 (70.0%) were unexposed and 266 (30.0%) were exposed to psychotropic medications. In the unexposed and exposed groups, the mean age, sex distribution, proportion with type 2 diabetes, initial BMI, and number of weight-loss medications prescribed were similar. At 12 months, the unexposed group lost 1.6% more weight on average than the exposed group (9.1% [SD 7.6%] vs. 7.5% [SD 8.1%], respectively; P = 0.02); 71.0% and 41.2% of the unexposed group achieved ≥ 5% and ≥ 10% weight loss at 12 months, respectively, compared with 63.1% and 31.8% in the exposed group at 12 months (P = 0.04 at 5%; P = 0.02 at 10%). Exposure to psychotropic medications was associated with diminished weight loss in patients with medically managed overweight and obesity.

The Use of Sleep Medication in Youth Residential Care.

Objectives: To investigate the use of sleep medication and concomitant psychotropic medication in children and adolescents placed under residential care (RC).Methods: Participants were youth 0–20 years of age placed in RC institutions at least once during 2016. Data on filled prescriptions were taken from the Norwegian Prescription Database to compare the use of sleep medication in RC with the general child population (GenPop) and how it covaried with gender, age, reasons for RC placement, and concomitant use of other psychotropic medications (antidepressants, anxiolytics, antipsychotics, and psychostimulants).Results: A total of 2171 youths were identified in RC at mean age 14 years (82% ≥ 13 years). Seventeen percent (371/2171) used sleep medications (melatonin 11%, alimemazine 7%, and benzodiazepines/z-hypnotics 2%) significantly more than the 2.3% who used in GenPop. The girl/boy ratio for medication use in RC was 1.8 (95% confidence interval [CI] = 1.5–2.2), not significantly different from the corresponding ratio in GenPop (1.4; 95% CI = 1.3–1.5). The use of sleep medication increased with age. When comparing reasons for placement in RC, medication use was particularly low among unaccompanied minor asylum seekers (2%). About half of the youths used concomitant psychotropic medication, with clear gender differences; girls used about twice as much antidepressants, anxiolytics, and antipsychotics, whereas boys used 1.3 times more psychostimulants.Conclusion: Youths in RC used more sleep medication and concomitant psychotropic medication than the GenPop, most likely reflecting the increased psychosocial strain and mental disorders reported in this population. Further studies of prevalence, assessment, and treatment of sleep problems in RC populations are warranted.

The Efficacy and Safety of Concomitant Psychotropic Medication and Electroconvulsive Therapy (ECT).

Electroconvulsive therapy (ECT) is an effective treatment for severe psychiatric disorders. Patients referred to ECT are often taking multiple medications, many of which can potentially affect the safety and efficacy of their course of ECT. This review evaluates the impact of a variety of psychotropic medications often used in conjunction with ECT and examines strategies to optimize their management. The review encompasses mood stabilizers, antidepressants, benzodiazepines, antiepileptics, antipsychotics, and other commonly used psychotropics.

Trends in attention-deficit and hyperactivity disorder (ADHD) medications among children and young adults in Ireland: a repeated cross-sectional study from 2005 to 2015

ObjectiveThis study examined the prescribing patterns of attention-deficit hyperactivity disorder (ADHD) medications in Ireland between 2005 and 2015 in children, adolescents and young adults, and concomitant use of psychotropic medication.DesignRepeated...

Validation and refinement of the clinical staging model in a French cohort of outpatient with schizophrenia (FACE-SZ)

ObjectiveExisting staging models have not been fully validated. Thus, after classifying patients with schizophrenia according to the staging model proposed by McGorry et al. (2010), we explored the validity of this staging model and its stability after one-year of follow-up. MethodUsing unsupervised machine-learning algorithm, we classified 770 outpatients into 5 clinical stages, the highest being the most severe. Analyses of (co)variance were performed to compare each stage in regard to socio-demographics factors, clinical characteristics, co-morbidities, ongoing treatment and neuropsychological profiles. ResultsThe precision of clinical staging can be improved by sub-dividing intermediate stages (II and III). Clinical validators of class IV include the presence of concomitant major depressive episode (42.6% in stage IV versus 3.4% in stage IIa), more severe cognitive profile, lower adherence to medication and prescription of >3 psychotropic medications. Follow-up at one-year showed good stability of each stage. ConclusionClinical staging in schizophrenia could be improved by adding clinical elements such as mood symptoms and cognition to severity, relapses and global functioning. In terms of therapeutic strategies, attention needs to be paid on the factors associated with the more stages of schizophrenia such as treatment of comorbid depression, reduction of the number of concomitant psychotropic medications, improvement of treatment adherence, and prescription of cognitive remediation.

Use of electroconvulsive therapy in adolescents with schizophrenia in China

BackgroundElectroconvulsive therapy (ECT) is an effective treatment for psychiatric disorders such as schizophrenia, major depression and bipolar disorder. However, few studies have addressed the use of ECT in adolescents with schizophrenia. The aims of our study were to investigate the frequency of ECT, and its relationship with clinical and demographic correlates among adolescents with schizophrenia in China.MethodsThe study was a retrospective study and conducted in the Child and Adolescent Psychiatry Department of Beijing Anding Hospital, and adolescents with schizophrenia over a period of 10 years (2007–2016) were enrolled. The demographic and clinical data were collected from the electronic chart management system.ResultsA total of 835 patients were included, 411/835 (49.2%) of the adolescent inpatients diagnosed with schizophrenia were in ECT group. There were significant differences in the sex, age, high risk for aggression and suicide, family history of psychiatric disorders and concomitant psychotropic medication (antidepressants and benzodiazepines) between the ECT and non-ECT groups. Multiple logistic regression analysis revealed that ECT use was independently and positively associated with sex, high risk for suicide.ConclusionsIn a major psychiatric center in China, the use of ECT was common, and reasons for the high use of ECT for adolescent patients in this hospital should warrant urgent investigations.

Off-Label Prescribing of Antipsychotics in a Danish Child and Adolescent Mental Health Center: A Register-Based Study.

Objective:We analyzed prescribing patterns of antipsychotics for children and adolescent affiliated with a Danish Child and Adolescent Mental Health Center) with respect to age, sex, medicine, diagnoses, off-label status, and time.Methods:We included all patients below 19 years of age prescribed antipsychotics during 2007–2008 and as of November 1, 2014. Prescription data included all antipsychotic prescriptions and prescriptions of concomitant psychotropic medications. We defined an antipsychotic user as a patient receiving at least one prescription during the study period, irrespective of any previous history of antipsychotic use. We defined off-label prescribing as prescriptions outside the licensed age group and approved indication.Findings:We analyzed 404 antipsychotic prescriptions that were located for 150 patients. The patients were between 7 and 18 years of age. Two-thirds of the prescriptions were for girls and two-thirds of prescriptions for olanzapine and quetiapine. Totally, 92% of all prescribed antipsychotics were used off-label. For typical antipsychotics, this share was 96% and for atypical antipsychotics 90%. As of November 1, 2014, the total share of off-label antipsychotic prescriptions was 96%, and 63% of these were for medications prescribed outside the approved age group, and 26% for nonlicensed indication(s).Conclusion:This study demonstrated a high level of off-label prescribing over time with respect to age and indication. The prescribing patterns underpin the need for further economic incentives for pharmaceutical companies to register pediatric indications, particular for off-patent products.

Concomitant Use of Psychotropic Medication With Stimulants for the Treatment of ADHD in Children and Adolescents: A Retrospective Insurance Claims Study in the United States

Objective: To evaluate annual concomitant psychotropic medication use among stimulant-treated children/adolescents with ADHD. Method: Children/adolescents with ≥1 primary ADHD diagnosis who had received ≥30 days of stimulant medication were identified from insurance claims for each calendar year (2011-2014). Use of 15 psychotropic medications concomitantly with stimulants was evaluated and their prevalence in each year was calculated overall and by medication category for children (6-12 years) and adolescents (13-17 years). Results: Each year 133,354 to 157,303 children and 95,632 to 111,280 adolescents were included. Annual period prevalence of any concomitant psychotropic medication use was 22.9% to 25.0% for children and 25.2% to 28.2% for adolescents. The most common medication categories included selective serotonin reuptake inhibitors (children: 6.8%-7.9%; adolescents: 12.7%-14.9%), atypical antipsychotics (4.2%-5.4%; 5.3%-6.3%), and guanfacine extended release (5.1%-7.0%; 2.3%-3.6%). Conclusion: Around a quarter of children/adolescents with ADHD were prescribed psychotropic medication concomitant to stimulant treatment, although only 2 of the 15 medication classes studied were Food and Drug Administration (FDA)-approved for adjunctive use.

Real-world Effectiveness of Pharmacologic Treatments for the Prevention of Rehospitalization in a Finnish Nationwide Cohort of Patients With Bipolar Disorder

ImportanceMood stabilizers and antipsychotics are the main maintenance treatments for bipolar disorder. Lithium is considered to be the most effective mood stabilizer, but very little is known about overall health outcomes associated with specific treatments and the comparative long-term effectiveness of specific psychotropics or routes of administration in the prevention of rehospitalizations.ObjectiveTo study the comparative effectiveness of pharmacologic treatments in the prevention of rehospitalization in a nationwide cohort of patients with bipolar disorder.Design, Setting, and ParticipantsThis cohort study examined the risk of psychiatric, cardiovascular, and all-cause hospitalization from January 1, 1987, to December 31, 2012, among all patients in Finland who had been hospitalized for bipolar disorder (N = 18 018; mean follow-up time, 7.2 years) using prospectively gathered nationwide databases for hospitalization and dispensed medications. The primary analysis was within-individual analysis, in which each individual was used as his or her own control to eliminate selection bias. The study adjusted for the effect of concomitant psychotropic medications, duration of illness, and the temporal orders of exposure and nonexposure periods. Statistical analysis was conducted from January 1, 1996, to December 31, 2012.Main Outcomes and MeasuresAdjusted hazard ratios (HRs) for rehospitalization were calculated.ResultsAmong the cohort (9558 women and 8460 men; mean [SD] age, 46.6 [17.0] years), 9721 patients (54.0%) had at least 1 psychiatric rehospitalization. In comparison between use and no use among specific agents reaching nominal statistical significance, risperidone long-acting injection (HR, 0.58 [95% CI, 0.34-1.00]), gabapentin (HR, 0.58 [95% CI, 0.44-0.77]), perphenazine long-acting injection (HR, 0.60 [95% CI, 0.41-0.88]), and lithium carbonate (HR, 0.67 [95% CI, 0.60-0.73]) were associated with the lowest risk of psychiatric rehospitalization. Concerning all-cause hospitalization, lithium (HR, 0.71 [95% CI, 0.66-0.76]) was associated with the lowest risk. The most frequently used antipsychotic treatment, quetiapine fumarate, showed only modest effectiveness (risk of psychiatric rehospitalization: HR, 0.92 [95% CI, 0.85-0.98]; risk of all-cause hospitalization: HR, 0.93 [95% CI, 0.88-0.98]). Long-acting injections were associated with substantially better outcomes compared with identical oral antipsychotics (risk of psychiatric rehospitalization: HR, 0.70 [95% CI, 0.55-0.90]; risk of all-cause hospitalization: HR, 0.70 [95% CI, 0.57-0.86]). Results from sensitivity analyses showed consistent beneficial effects only for lithium and for long-acting injections compared with their oral counterparts.Conclusions and RelevanceLithium was the most effective mood stabilizer, and long-acting injections the most effective antipsychotics, in preventing hospitalization due to mental or physical illness.

Potentially inappropriate medication use in nursing homes: an observational study using the NORGEP-NH criteria

BackgroundFrail residents in the nursing home sector call for extra care in prescribing. The Norwegian General Practice Nursing Home (NORGEP-NH) list of 34 explicit criteria for potentially inappropriate medication use in nursing homes was developed explicitly for this population. The aim of this study was to employ the NORGEP-NH Criteria to study the extent of potentially inappropriate medication use among nursing home residents and explore possible associated factors.MethodsCross-sectional observational pharmacoepidemiological study from residents in nursing homes in the county of Vestfold, Norway. Data collected 2009–11 included residents’ demographic and clinical status and all medications, regular and on demand.Results881 patients from 30 institutions (mean 85.9 years, 68.6% female), were included. According to NORGEP-NH, 43.8% were prescribed at least one potentially inappropriate regular medication, and 9.9% regularly received three or more potentially inappropriate medications. When also including a) the NORGEP-NH Deprescribing Criteria and b) including drugs prescribed for use as needed, 92.7% of all residents received medication that needs particular surveillance according to the NORGEP-NH. 69.7% of the nursing home residents used at least one psychotropic drug regularly. Female residents received more often than males at least one potentially inappropriate regular medication (OR 1.60, p=0.007). Regarding the prescription of three or more concomitant psychotropic medications, odds ratio for females was 1.79 (p=0.03) compared to males. Residents with the best performance in activities of daily living, and residents residing in long-term wards, had higher risk of using three or more psychotropic drugs. Use of multiple psychoactive drugs increased the risk of falls in the course of an acute episode of infection or dehydration (odds ratio 1.70, p=0.009).ConclusionsPrevalence of potentially inappropriate medications in nursing homes according to the NORGEP-NH was extensive, and especially the use of multiple psychotropic drugs. The high prevalence found in this study shows that there is a need for higher awareness of medication use and side effects in the elderly population.Trial registrationRetrospectively registered. Data obtained from clinical trial NCT01023763 registered with ClinicalTrials.gov 12/01/2009.

Concomitant psychotropic medications and functional remission in schizophrenia patients

Along with the rise of symptomatic and functional remission concepts in schizophrenia, multiple aspects of the disease treatment have been explored in their link to vocational prognosis. Although antipsychotics are the corner stone treatment, monotherapy is seldom. In fact, concomitant psychotropic medications (CPM) use during treatment of schizophrenia has dramatically increased worldwide.AimTo examine whether concomitant psychotropic medications use is associated to functional remission in schizophrenia patients.MethodsA cross-sectional, retrospective and descriptive study was conducted in the psychiatry department “C”, in Razi hospital (Tunis), between October 2014 and March 2015. Sixty patients suffering from schizophrenia spectrum disorder (DSM IV-R) were included. Functional status was explored with the Global Assessment of Functioning Scale (GAF), the Social and Occupational Functioning Assessment scale and the Social Autonomy Scale (EAS). Sociodemographic and therapeutic characteristics have been collected during a semi-structured interview.ResultsRates of functional remission were respectively: 63.30% at the GAF scale, 48.30% at the SOFAS and 51.70% at the SAS. Antipsychotics were prescribed alone in more than half patients (56.70%), mood stabilizers in 40% and antidepressants in 1.7% of the cases. Benzodiazepines were prescribed in 40% of the patients. There was no association between CPM use and functional remission, using three scales (GAF: P = 0.091; SOFAS = 0.125; EAS = 0.728).ConclusionLargely used, concomitant psychotropic medications can increase side effects, cause drug interactions, escalate treatment costs, and lead to non-adherence. That is said, their therapeutic effectiveness should be thoroughly investigated, aiming to recovery not only symptoms control.Disclosure of interestThe authors have not supplied their declaration of competing interest.
