Functional recovery in patients with schizophrenia: recommendations from a panel of experts.

BACKGROUND: The management of schizophrenia is evolving towards a more comprehensive model based on functional recovery. The concept of functional recovery goes beyond clinical remission and encompasses multiple aspects of the patient's life, making it difficult to settle on a definition and to develop reliable assessment criteria. In this consensus process based on a panel of experts in schizophrenia, we aimed to provide useful insights on functional recovery and its involvement in clinical practice and clinical research. METHODS: After a literature review of functional recovery in schizophrenia, a scientific committee of 8 members prepared a 75-item questionnaire, including 6 sections: (I) the concept of functional recovery (9 items), (II) assessment of functional recovery (23 items), (III) factors influencing functional recovery (16 items), (IV) psychosocial interventions and functional recovery (8 items), (V) pharmacological treatment and functional recovery (14 items), and (VI) the perspective of patients and their relatives on functional recovery (5 items). The questionnaire was sent to a panel of 53 experts, who rated each item on a 9-point Likert scale. Consensus was achieved in a 2-round Delphi dynamics, using the median (interquartile range) scores to consider consensus in either agreement (scores 7-9) or disagreement (scores 1-3). Items not achieving consensus in the first round were sent back to the experts for a second consideration. RESULTS: After the two recursive rounds, consensus was achieved in 64 items (85.3%): 61 items (81.3%) in agreement and 3 (4.0%) in disagreement, all of them from section II (assessment of functional recovery). Items not reaching consensus were related to the concepts of functional recovery (1 item, 1.3%), functional assessment (5 items, 6.7%), factors influencing functional recovery (3 items, 4.0%), and psychosocial interventions (2 items, 5.6%). CONCLUSIONS: Despite the lack of a well-defined concept of functional recovery, we identified a trend towards a common archetype of the definition and factors associated with functional recovery, as well as its applicability in clinical practice and clinical research.

An open-treatment six-week study of the clinical effectiveness of Paliperidone Palmitate in schizophrenia: data from acute units in Spain (SHADOW study).

OBJECTIVES: To evaluate clinical evolution of patients with schizophrenia admitted in acute units because of a relapse and treated with once-monthly Paliperidone Palmitate (PP1M). METHODS: This multicentre, open-label, prospective observational study followed patients with schizophrenia treated with PP1M in acute psychiatric units for up to 6 weeks. RESULTS: Out of the 280 enrolled patients, 61 received PP1M as antipsychotic monotherapy, and 219 in combination with other antipsychotics. The average Clinical Global Impression-Schizophrenia (CGI-SCH) score decreased from 4.7 at baseline to 3.3 at final visit (p < .0001); the change was clinically and statistically significant both in patients treated with PP1M in monotherapy and in combination with other antipsychotics. Clear improvements in functioning and high patient satisfaction with the treatment were observed. Time from admission to PP1M therapy initiation correlated with the length of hospital stay (p < .0001); earlier start of PP1M treatment was associated with shorter hospital stay. Adverse events were reported in 7.1% of patients (all non-serious). CONCLUSIONS: PP1M was effective and well tolerated in treatment of acute episodes of schizophrenia both in monotherapy and in combination with other antipsychotics in clinical setting. Early start of PP1M therapy in acute schizophrenia episodes might help to shorten hospital stay.

Epidemiology and costs of depressive disorder in Spain: the EPICO study.

Depressive Disorders are the most common psychiatric diagnoses in the general population. To estimate the frequency, costs associated with Depressive Disorders in usual clinical practice, and in the whole Spanish population, a longitudinal, retrospective, observational study was carried out using data from the BIG-PAC database®. Study population: all patients aged ≥ 18 years with a diagnosis of a Depressive Disorder in 2015-2017. Prevalence was computed as the proportion of Depressive Disorder cases in the adult general population, and the incidence rate, as the number of new Depressive Disorder cases diagnosed per 1,000 person-years in the population using health services, during 2015-2017. We collected demographic variables, comorbidity, direct health costs, and indirect costs (temporary and permanent disability). Health costs related to Depressive Disorders were estimated according to the annual resource use rate (resource/patient/year). Indirect costs were calculated according to the human capital method. Using the study data and information from the Spanish National Institute of Statistics, we estimated the cost of Depressive Disorders corresponding to the Spanish adult population, including premature mortality. 69,217 Depressive Disorder patients aged ≥ 18 years who met the inclusion/exclusion criteria were studied (mean age: 56.8 years; female: 71.4%). Prevalence of Depressive Disorders in the general population was 4.73% (95% CI: 4.70-4.76%). Annual incidence rates (2015-2017) were 7.12, 7.35 and 8.02 per 1,000 person-years, respectively. Total costs observed in our Depressive Disorder patients were € 223.9 million (corresponding to a mean of € 3,235.3; mean/patient/year), of which, 18.4% were direct health care costs and 81.6%, non-health indirect costs (18% temporary occupational disability, 63.6% permanent disability). Considering also the cost of premature death, the mean cost per patient/year was € 3,402 and the estimated societal costs of Depressive Disorders in Spain were € 6,145 million. The prevalence and incidence of Depressive Disorders are consistent with other series reviewed. Resource use and total costs (especially non-health costs) were high.

Economic impact of treatment-resistant depression: A retrospective observational study.

BACKGROUND: To determine the incidence of Treatment-Resistant Depression (TRD) in Spain and to estimate its economic burden, using real world data. METHODS: A retrospective, observational-study was carried out using data from the BIG-PAC database®. Patients aged ≥18 years with a diagnosis of major depressive-disorder (MDD) who initiated a new antidepressant treatment in 2015-2017 were included. The patients were classified as TRD and non-TRD. Patients were classified as TRD if they had, during the first year of antidepressant treatment: a) failure with ≥2 antidepressants including the prescription of ≥3 antidepressants (N06A) or ≥2 antidepressant and ≥1 antipsychotic (N05A; including lithium) b) antidepressants administered for ≥ 4 weeks each, and c) the time between the end of one treatment and the initiation of the next was ≤ 90 days. Inherent limitations of data collection from databases should also be considered in this analysis (e.g., lack of information about adherence to treatment). Follow-up period: 18 months. The incidence rate was calculated as the number of TRD patients per 1,000 persons-year divided by the population attended. OUTCOMES: direct healthcare and indirect costs. Two sensitivity analyses were performed varying the index date and the period used to define TRD patients (6 vs.12 months). RESULTS: 21,630 patients with MDD aged ≥ 18 years (mean age: 53.2 years; female: 67.2%) were analyzed, of whom 3,559 met TRD criteria, yielding a 3-year cumulative incidence of 16.5% (95%CI: 16%-17%) among MDD patients. The annual population incidence rate of TRD in 2015-2017, was 0.59, 1.02 and 1.18/1,000 person-years, respectively (mean: 0.93/1,000 person-year). Overall, mean total costs per MDD patient were €4,147.9, being higher for TRD than for non-TRD patients (€6,096 vs. €3,846; p<0.001): a) direct costs (€1,341 vs. €624; p<0.001), b) lost productivity (€1,274 vs. €821; p<0.001) and c) permanent disability (€3,481 vs. €2,401; p<0.001, adjusted). Sensitivity analyses showed no differences with the reported results. CONCLUSIONS: The population based TRD incidence in Spain was similar to recent data from other European countries. TRD is associated with greater resource use and higher costs compared with non-TRD patients.

Real-world data on paliperidone palmitate for the treatment of schizophrenia and other psychotic disorders: a systematic review of randomized and nonrandomized studies.

The aim of this study was to perform a systematic review of the effects of 1-month paliperidone palmitate (PP1M) for the treatment of schizophrenia and related psychotic disorders in terms of outcomes reported in real-world evidence studies. A systematic review of real-world randomized and nonrandomized studies with PP1M was performed and is reported according to PRISMA guidelines. Comparative effectiveness data with oral antipsychotics indicate that PP1M has a lower likelihood of relapse-related events, including rehospitalization, and these differences are clinically relevant. A randomized, double-blind study showed that PP1M has no advantage over haloperidol decanoate in the time to treatment failure. Although there was a marked variability across studies, PP1M was not superior to other antipsychotics in terms of study completion rates. Pharmacoeconomic data show that, during a follow-up period of 12 months, the mean total healthcare cost was not significantly different in patients treated with PP1M compared with those receiving oral antipsychotics. The mean maximum prolactin levels were significantly higher with PP1M than with haloperidol decanoate; however, neither drug differs in the frequency of prolactin-related adverse events. Results on prolactin-related adverse events were inconsistent in two randomized comparisons with oral antipsychotics and were not reported in a randomized comparison with aripiprazole. There were no significant differences between haloperidol decanoate and PP1M in the severity of abnormal involuntary movements and parkinsonism, or in the incidence of tardive dyskinesia; however, patients treated with haloperidol decanoate showed greater worsening of akathisia and required treatment for parkinsonism and akathisia significantly more frequently than patients who received PP1M. In conclusion, real-world data that originate from both pragmatic randomized clinical trials and observational studies indicate that PP1M is superior to oral antipsychotics in delaying the time to relapse or treatment failure. Furthermore, the pharmacoeconomic data reviewed for this article suggest that the advantages of PP1M compared with oral antipsychotics are not associated with an increased total cost for healthcare providers.

Adherence predicts symptomatic and psychosocial remission in schizophrenia: Naturalistic study of patient integration in the community. / La adherencia predice la remisión sintomática y psicosocial en esquizofrenia: estudio naturalístico de la integración de los pacientes en la comunidad.

INTRODUCTION: Psychosocial functioning in patients with schizophrenia attended in daily practice is an understudied aspect. The aim of this study was to assess the relationship between symptomatic and psychosocial remission and adherence to treatment in schizophrenia. METHODS: This cross-sectional, non-interventional, and multicenter study assessed symptomatic and psychosocial remission and community integration of 1,787 outpatients with schizophrenia attended in Spanish mental health services. Adherence to antipsychotic medication in the previous year was categorized as≥80% vs.<80%. RESULTS: Symptomatic remission was achieved in 28.5% of patients, and psychosocial remission in 26.1%. A total of 60.5% of patients were classified as adherent to antipsychotic treatment and 41% as adherent to non-pharmacological treatment. During the index visit, treatment was changed in 28.4% of patients, in 31.1% of them because of low adherence (8.8% of the total population). Adherent patients showed higher percentages of symptomatic and psychosocial remission than non-adherent patients (30.5 vs. 25.4%, P<.05; and 32 vs. 17%, P<.001, respectively). Only 3.5% of the patients showed an adequate level of community integration, which was also higher among adherent patients (73.0 vs. 60.1%, P<.05). CONCLUSIONS: Adherence to antipsychotic medication was associated with symptomatic and psychosocial remission as well as with community integration.

Introduction: studies on Maytenus trees comprising forsskaoliana, krukovii, and ilicifolia species showed depressing effects on the blood pressure and the heart rate. Objectives: to experimentally analyze the effects of Maytenus macrocarpa leaves on the heart rate, the electrocardiographic patterns, the respiratory rate, and the temperature. Method: this study was exploratory, analytical, and experimental. Albino rats were grouped in 9 groups of 8 rats each. Group 1 (control: Halatal), group 2 (placebo: distillated water), group 3 (adrenaline), group 4 (atropine), group 5 (acetylcholine), group 6 (propranolol), group 7 (500 mg/kg chuchuhuasi), group 8 (1 000 mg/kg chuchuhuasi), and group 9 (1 500 mg/kg chuchuhuasi). The rectal temperature was measured with a mercury thermometer, whereas the direct count allowed measuring the respiratory frequency. The polygraph registered electrocardiogram and heart rate as well. The MATLAB program analyzed data from the electrocardiogram. The statistic validation was performed with ANOVA, Tuckey, Wilcoxon, and Shapiro-Wilk tests. Results: Maytenus macrocarpa showed depressing effects on the cardiac frequency, being more effective at 1 500 mg/kg doses (average 308.6 ppm), higher negative inotropic effect at 1 500 mg/kg doses (average P wave 0.08300 mv, average R wave 0.1539 mV). Severe bradypnea was shown at 1 500 mg/kg doses (average RF 51.6 rpm), as well as hypothermia (average T° 31.84 °C). Conclusion: Maytenus macrocarpa demonstrated bradycardic as well as depressing effects on respiratory frequency and body temperature.
