Relationship between clinical outcomes measures and personal and social performance functioning in a prospective, interventional study in schizophrenia. Int J Methods Psychiatr Res 2021; 30:e1855. [PMID: 33355966 PMCID: PMC8170566 DOI: 10.1002/mpr.1855] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Revised: 08/12/2020] [Accepted: 09/24/2020] [Indexed: 11/22/2022] Open
Abstract
OBJECTIVES To explore clinical and demographic characteristics impacting patient functioning by determining extent of overlap in factors driving change in Personal and Social Performance (PSP) and other clinical outcomes. METHODS Post-hoc analysis from a single-arm trial of paliperidone extended release in adult patients with nonacute symptomatic schizophrenia. Psychosocial functioning measures: PSP, Clinical Global Impression-Severity (CGI-S), Positive and Negative Syndrome Scale (PANSS), Short-Form 36 (SF-36), treatment satisfaction, sleep quality/daytime drowsiness, and Extrapyramidal Symptoms Rating Scale. RESULTS Highest correlations with PSP total score change included PANSS total score change (Spearman's r = 0.607), PANSS general psychopathology change (r = 0.579), and CGI-S change (r = 0.569). A PSP score change of -32 predicted 90% probability of deterioration in CGI-S (score change of ≥1). The power of PSP change to predict PANSS total score change was lower. Linear stepwise regression demonstrated independent relationships for PSP change and: PANSS total change; CGI-S change; SF-36 Mental Component change; treatment satisfaction at endpoint; PSP at baseline; previous psychiatric hospitalizations. R 2 = 0.55 meant that 45% of PSP variation could not be explained by other clinical outcome measures. CONCLUSIONS Psychosocial functioning improvement is important in schizophrenia. PSP may be valuable for assessing functioning; it encompasses psychosocial and clinical factors not measured by other established assessments.

Abstract
Objective:To report the functional recovery results from an open-label, randomized-controlled, relapse prevention trial (ConstaTRE) in stable patients with schizophrenia or schizoaffective disorder treated with risperidone long-acting injectable (RLAI) or the oral atypical antipsychotic quetiapine.Methods:Clinically stable adults with schizophrenia or schizoaffective disorder previously treated with oral risperidone, olanzapine, or oral conventional antipsychotics were randomized to treatment with either RLAI (25 mg every-two-weeks) or quetiapine (300-400 mg/day) for 24 months. Functional recovery was assessed using the Social and Occupational Functioning Assessment Scale (SOFAS) and two quality-of-life (QoL) measures (Short -Form 12 [SF-12] and Schizophrenia Quality-of-Life Scale Revision 4 [SQLS-R4]).Results:710 subjects were randomized to treatment with RLAI or quetiapine (n=355 patients/group). Baseline demographics were similar between treatment groups. Relapse occurred in 16.5% RLAI and 31.3% quetiapine patients. A total of 105 RLAI and 107 quetiapine patients dropped out of the study for other reasons than relapse, most commonly due to withdrawal of consent. A significant improvement in SOFAS, SF-12, and SQLS-R4 scores was observed from baseline to month-24 with both RLAI and quetiapine. at months 6, 12, and endpoint, SOFAS had significantly increased more for RLAI than quetiapine (p< 0.05).Conclusions:Among stable patients with schizophrenia or schizoaffective disorder, the likelihood of functional recovery appears to be higher in those switching to RLAI. Improvement in functional status and QoL from baseline was observed with both RLAI and quetiapine.

Abstract
Objective:This post-authorization safety survey evaluated the long-term safety, tolerability, and efficacy of risperidone long-acting injectable (RLAI) in routine clinical practice.Methods:In this 6-month, multicenter, European, naturalistic survey, patients were included if, during routine clinical practice, long-term antipsychotic therapy with RLAI was deemed necessary by the treating physician. Efficacy measures (at baseline and after 1, 3, 6 months) included Clinical Global Impression-Severity (CGI-S) and Global Assessment of Functioning (GAF). Safety was evaluated by recording treatment-emergent adverse events (TEAEs) at every visit.Results:RLAI was initiated in 5,134 predominantly male (58.6%) patients (aged 14-94 years) with a diagnosis of paranoid schizophrenia (69.8%). RLAI initial doses were 25 mg every-two-weeks in 37.0%, or 50 mg in 44.4% of patients. at endpoint, RLAI dosages were 50 mg in 49.3% of patients, 25 mg in 27.0%, and 37.5 mg in 22.1%. Six-month treatment with RLAI was completed by 4,314 patients (84.0%). RLAI was discontinued due to loss to follow-up (n=346;6.7%), insufficient response (n=116;2.3%), and AEs (n=106;2.1%). CGI-S significantly improved from baseline to endpoint (p< 0.001). Patient functioning in the GAF scale also significantly improved from baseline to endpoint (45.4±16.0 versus 62.4±17.7, respectively, p< 0.001). TEAEs were recorded by 20% of patients. AEs occurring in ≥5% of patients were akathisia, extrapyramidal disorders, depression, psychotic disorder, anxiety, and weight gain. Serious AEs were reported by 384 (8%) patients.Conclusions:This large prospective survey confirms the good safety, tolerability, and efficacy of RLAI as reported in previous controlled clinical trials when used in routine clinical practice.

Abstract
Objective:To report the long-term remission results from the relapse prevention trial (ConstaTRE) in stable patients treated either with risperidone long-acting injectable (RLAI) or the oral atypical antipsychotic quetiapine.Methods:Clinically stable adults with schizophrenia or schizoaffective disorder treated with oral risperidone, olanzapine, or oral conventional antipsychotics were randomized to treatment with RLAI or oral quetiapine. Dosing was according to package-insert recommendation. Efficacy and tolerability were recorded for up to 24 months of treatment. Remission was defined as achieving and maintaining mild or less symptoms of schizophrenia over a 6-month period as defined by Andreasen et al, (2005).Results:710 patients were randomized (n=355 per group) to either RLAI or quetiapine. Demographics were similar between treatment groups. Relapse occurred in 54 RLAI (16.5%) and 102 quetiapine (31.3%) patients (p< 0.001). Full remission was achieved by 51% RLAI and 39% of quetiapine-treated patients (p=0.003) and was maintained until the end of the trial by 44% of RLAI and 31% of quetiapine patients. Mean duration of full remission was 540.8±181.4 and 508.1±188.0 days for RLAI and quetiapine groups, respectively (p=0.1325). Tolerability was similar between treatment groups. Most adverse events (AEs) were transient. Six RLAI and 10 quetiapine patients discontinued study treatment due to AEs.Conclusions:Among stable patients with schizophrenia or schizoaffective disorder, remission was more likely to occur in patients switching to RLAI when compared with quetiapine. both RLAI and quetiapine treatments were well tolerated.

Abstract
IntroductionLittle is known about patient characteristics and rehospitalization in newly diagnosed patients with schizophrenia treated with long-acting antipsychotics.ObjectivesTo retrospectively explore hospitalizations, drug utilization and clinical outcomes from medical records of young, newly diagnosed schizophrenia patients during the first 12 months of treatment with once-monthly paliperidone palmitate (PP).MethodsInternational, multicenter, retrospective, observational study. Outcomes presented are patient characteristics, reason for PP initiation and hospitalization data.ResultsEighty-four patients were analyzed: mean age (years) at first psychotic episode was 23.8 (SD2.6), 23.9 (SD2.6) at first antipsychotic treatment and 24.1 (SD2.7, range 19-29) at PP initiation. Time between first antipsychotic treatment and PP initiation was 4.8 (SD: 3.4, range: 0-12) months. At PP initiation, 42.9% of patients were in hospital, primarily for the management of the first episode/relapse (97.2%). Reason for PP initiation was: LAT favored over oral treatment for relapse prevention (56%), partial/non adherence with previous oral medication (20.0%), convenience (15.5%) or limited access to health care systems (2.4%). Mean time (days) between admission and initiation of PP, and between initiation of PP and discharge from hospital was 28.8 (SD23.0) and 23.2 (SD24.5), respectively. 96.4% of patients were not hospitalized during the 12-month PP treatment period. 3/84 patients (3.6%) had a single hospitalization of 15.7 (SD: 8.1) days for management of episode/relapse.ConclusionsIn this young, newly diagnosed schizophrenia population, the number of hospitalizations following PP initiation was low. Main reason to initiate PP was clinicians favoring LAT over oral antipsychotic treatment for relapse prevention or due to partial/non adherence with previous oral treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Preventing Cross-Contamination during Lyophilization: GMP and Occupational Cleaning Requirements for Nonproduct and Indirect Product-Contact Parts. PDA J Pharm Sci Technol 2019; 73:487-495.

Abstract
A detailed overview is provided for the possible patient exposure to highly potent active pharmaceutical ingredients (HPAPIs) from potential cross-contamination through the lyophilization process. The intent of this paper is to raise awareness of the risk(s) to patients and stimulate the implementation of adequate risk-based controls, such as containment process(es), use of adequate surrogates in cleaning validation/verification, and test method-sensitivity-based cleaning validation acceptance conditions. Although lyophilizers are considered to be nonproduct-contact surfaces because their surfaces and fixtures do not usually come into direct contact with the product, product contamination can occur at critical locations within a lyophilizer and/or during the unloading process. Contamination of the air because of released product particles can also create a risk. Therefore, special attention should be paid to HPAPIs, as the permitted daily exposures (PDEs) for patients are particularly low. During a lyophilizer cycle, areas of concern are spreading of the lyophilizer HPAPI powder because of air turbulence, contaminated plates, mechanical transfer systems, and spreading because of damaged vials or contaminated stainless steel or plastic surfaces. Specific considerations for contamination containment for the lyophilizer unloading process are presented. Suggestions are provided for the prevention of patient exposure through cross-contamination via direct-contact areas and prevention of manufacturing personnel exposure via non-direct-contact areas. A surface limit(s) of 1 PDE per square decimeter for nonproduct-contact surfaces inside a lyophilizer is proposed. Risk-based cleaning validation/verification strategies are discussed, with specific consideration of the quality control test method sensitivity expectations and use of suitable surrogates for lyophilized products in the cleaning verification studies.LAY ABSTRACT: This paper provides an overview of important points to consider during the manufacture of highly potent active pharmaceutical ingredients (HPAPI) with the intention to limit patient exposure and/or manufacturing personnel exposure to these highly toxic HPAPIs. HPAPI can potentially be spread during the freeze-drying process (lyophilization) and may cross-contaminate products. Manufacturing personnel and patients taking other freeze-dried products made in the same lyophilizer could be contaminated. It is therefore necessary to implement rigorous contamination controls. Within the lyophilizer, areas of concern are spreading of the lyophilizer HPAPI powder because of air turbulence, contaminated plates, mechanical transfer systems, and spreading because of damaged vials or contaminated stainless steel or plastic surfaces. Cleaning validation/verification studies, intended to demonstrate sufficient cleanability of the freeze-drying process as well as the recommended test method sensitivity to detect these highly toxic HPAPIs, are reviewed. Limits for the relevant production surface areas where cross-contamination and/or personnel exposure (through direct contact) could occur are proposed in this paper.

Abstract
OBJECTIVES Partial or non-adherence in patients with schizophrenia is common and increases the risk of relapse. This study explored safety, tolerability and treatment outcomes in patients hospitalised for an exacerbation of schizophrenia initiated on maintenance treatment of once-monthly paliperidone palmitate (PP1M). METHODS A 6-week, observational cohort study of patients initiated on PP1M within 3 weeks after hospital admission. RESULTS Overall, 367 patients were documented, 85.8% with paranoid schizophrenia subtype. Mean time from hospital admission to PP1M initiation was 9.4 ± 7.7 days. Treatment-emergent adverse events were reported by 22.9% of patients. From baseline to endpoint, significant improvements were observed in psychotic symptoms (Brief Psychiatric Rating Scale total score mean change -19.3 ± 12.6, P < .0001) and functioning (Personal and Social Performance scale total score mean change 14.3 ± 12.4, P < .0001). Overall, 6.0% of patients were very or extremely satisfied with their prior antipsychotic medication at baseline compared with 47.2% very or extremely satisfied with PP1M treatment at endpoint. CONCLUSIONS Initiating PP1M in patients with exacerbated schizophrenia shortly after hospital admission was well tolerated and resulted in statistically significant and clinically relevant improvements in symptoms and patient functioning, suggesting that patients may benefit from early initiation of PP1M during their hospital stay.

Abstract
AbstractThe use of an expert system shell (EXPERTECH Xi Plus) in the construction of an expert system for the diagnosis of infertility has been evaluated. A module was devised for predicting ovulation from the medical history alone. Two versions of this system were constructed, one using the expert system shell, and the other using QuickBASIC. The two systems have been compared with respect to: (1) ease of construction; (2) ease of knowledge base update; (3) help and explanation facilities; (4) diagnostic accuracy; (5) acceptability to patients and clinicians; (6) user-friendliness and ease of use; (7) use of memory space; and (8) run time. The responses of patients and clinicians were evaluated by questionnaires. The predictions made by the computer systems were compared to the conclusions reached by clinicians and to the “gold standard” of day 21 progesterone.The conclusions of this pilot study are: (1) the construction of this expert system was NOT facilitated by the use of this expert system shell; (2) update of the knowledge base was not facilitated either; (3) the expert system shell offered built-in help and explanation facilities, but as the system increased in complexity these became less useful; (4) after initial adjustment of decision thresholds the diagnostic accuracy of the system equalled that of the clinician; (5) the patient response to computer history-taking was very favorable but much less favorable to computer diagnosis; (6) the clinicians took a positive attitude to computer diagnosis; (7) the systems were easy to use; (8) the expert systems shell required much more memory space and had a much slower response time than the system written in BASIC.

Abstract
BACKGROUND The negative symptoms of schizophrenia are generally harder to recognize, more difficult to treat than positive symptoms, and have a significant impact on patient functioning and overall outcomes. Treatment with aripiprazole may be associated with benefits on negative symptoms and functioning given its partial agonism to the dopamine D2 receptor. The aim of this subanalysis was to explore the impact of flexibly dosed, long-acting paliperidone palmitate once monthly (PP1M) on negative and depressive symptoms, disorganized thoughts, anxiety, extrapyramidal symptoms, and patient functioning in nonacute adult patients with schizophrenia previously unsuccessfully treated with oral aripiprazole monotherapy. METHODS Post-hoc subanalysis of 46 nonacute but symptomatic patients enrolled in a prospective, interventional, single-arm, multicenter, open-label 6-month study. RESULTS At endpoint, improvements of ⩾ 20% and ⩾ 50% in the Positive and Negative Syndrome Scale (PANSS) total score were observed in 52.2% and 21.7% of patients, respectively. Significant and clinically relevant improvements were observed at endpoint in mean (standard deviation [SD]) PANSS negative subscale score (-3.0 (5.0); p < 0.0001) and in the PANSS Marder factor scores for negative symptoms (-2.9 (5.4); p = 0.0006), disorganized thoughts (-2.8 (4.3); p < 0.0001) and anxiety/depression (-1.8 (3.9); p = 0.0031). Patient functioning assessed by mean (SD) Personal and Social Performance scale score (3.9 (13.2); p = 0.0409), Mini International Classification of Functioning rating for Activity and Participation Disorders in Psychological Illnesses total scores (-2.9 (7.1); p = 0.0079), and Extrapyramidal Symptom Rating Scale scores (-0.6 (3.4); p = 0.0456) improved significantly at endpoint. PP1M was well tolerated with no new safety signals. CONCLUSIONS Six-month treatment with flexibly dosed PP1M was associated with significant and clinically relevant improvements in negative and depressive symptoms, disorganized thoughts, functioning, and extrapyramidal symptoms in nonacute but symptomatic patients with schizophrenia previously unsuccessfully treated with oral aripiprazole.

Abstract
BACKGROUND Long-acting antipsychotic therapy may be best suited for patients in the early stage of schizophrenia, when the most can be done before disease progression associated with poor adherence occurs. We explored the patterns of use of once-monthly paliperidone palmitate (PP1M), concomitant medication use, hospitalization, and clinical outcomes of adult, newly diagnosed patients with schizophrenia receiving continuous treatment with PP1M for at least 12 months. METHODS This was an international, multicenter, exploratory, retrospective chart review of medical records of adult patients who were newly diagnosed (not more than 1 year before initiation of PP1M treatment) with schizophrenia and who had received continuous treatment with PP1M for ≥12 months in naturalistic clinical settings. RESULTS A total of 84 (93.3%) patients were included in the analysis. All but one patient (98.8%, n=83) had received oral antipsychotic medication at least during the last month before the first PP1M administration. Three patients (3.6%) were newly hospitalized during the 12-month documentation period. The reason for hospitalization for all three was management of episode/relapse. A total of 79.2% of patients had a ≥20% improvement and 47.2% had a ≥50% improvement in Positive and Negative Syndrome Scale total score from baseline to endpoint. Half of patients (53.3%) showed a significant improvement, as reflected by an increase in Personal and Social Performance (PSP) total score of at least 7 points from baseline to endpoint (mean [SD] 11.9 [15.0] points; P<0.001). One quarter of patients (24.4%, n=11) moved from a PSP score of 31-70 (ie, moderate to marked functional impairment) at baseline to a PSP score of mild to no functional impairment (PSP score ≥71) at endpoint. Most adverse drug reactions were mild or moderate in severity. CONCLUSION Continuous treatment with PP1M over 12 months was associated with statistically significant and clinically meaningful improvements in psychotic symptoms, disease severity, and functional outcomes in patients with schizophrenia.

Abstract
Objective: To explore the treatment response, tolerability and safety of once-monthly paliperidone palmitate (PP1M) in non-acute patients switched from oral antipsychotics, stratified by time since diagnosis as recently diagnosed (≤3 years) or chronic patients (>3 years). Research design and methods: Post hoc analysis of a prospective, interventional, single-arm, multicentre, open-label, 6-month study performed in 233 recently diagnosed and 360 chronic patients. Main outcome measures: The proportion achieving treatment response (defined as ≥20% improvement in Positive and Negative Syndrome Scale [PANSS] total score from baseline to endpoint) and maintained efficacy (defined as non-inferiority in the change in PANSS total score at endpoint [Schuirmann’s test]). Results: 71.4% of recently diagnosed and 59.2% of chronic patients showed a ≥20% decrease in PANSS total score (p = 0.0028 between groups). Changes in PANSS Marder factors, PANSS subscales, and the proportion of patients with a Personal and Social Performance scale (PSP) total score of 71–100 were significantly greater in recently diagnosed compared with chronic patients. PP1M was well tolerated, presenting no unexpected safety findings. Conclusion: These data show that recently diagnosed patients treated with PP1M had a significantly higher treatment response and improved functioning, as assessed by the PSP total score, than chronic patients.

Abstract
OBJECTIVE Relapse and acute exacerbation are common in schizophrenia and may impact treatment response and outcome. Evidence is conflicting in respect to superiority of long-acting injectable antipsychotic therapies versus oral antipsychotics in relapse prevention. This randomized controlled study assessed the efficacy of paliperidone palmitate versus oral antipsychotics for relapse prevention. METHOD Eligible patients with a recent diagnosis of schizophrenia (within 1-5 years) were randomized 1:1 to paliperidone palmitate (n=376) or oral antipsychotic monotherapy (n=388) and entered a 2-week initial acute oral treatment phase. Patients who met predefined response criteria were eligible to enter the 24-month rater-blinded core treatment phase. Patients were evaluated for relapse, symptoms, functioning, quality of life, treatment satisfaction, and tolerability. RESULTS In the core treatment phase, time to relapse was significantly longer in the paliperidone palmitate (n=352) compared with the oral antipsychotics arm (n=363): 85% of patients were relapse-free at 469 versus 249 days (P=0.019). Significantly fewer patients receiving paliperidone palmitate met the relapse criteria (52 [14.8%] versus 76 [20.9%, oral antipsychotics]; P=0.032), representing a 29.4% relative risk reduction. For paliperidone palmitate, a significantly greater improvement in Positive and Negative Syndrome Scale total score on Day 8 (P=0.021) and a trend at endpoint (P=0.075) were observed. Functioning improvements were comparable between treatment arms. No new safety signals were identified. CONCLUSION The observed time to relapse superiority of paliperidone palmitate over oral antipsychotics provides further evidence for the value of long-acting injectable antipsychotic therapies in the treatment of schizophrenia, including during the early stages of illness.

Abstract
OBJECTIVES Poor adherence to antipsychotic treatment is a widespread problem within schizophrenia therapy with serious consequences including increased risks of relapse and rehospitalization. Mounting evidence supports the key roles that nurses play in monitoring patient progress and facilitating long-term treatment adherence. The Adherencia Terapéutica en la Esquizofrenia (ADHES) nurses' survey was designed to assess the opinions of nurses on the causes and management of partial/nonadherence to antipsychotic medication. METHODS A questionnaire-based cross-sectional survey of 4120 nurses from Europe, the Middle East and Africa. Interpretation of results was based on a descriptive comparison of responses. RESULTS Nurses perceived 54% of patients seen in the preceding month to be partially/nonadherent to treatment. Most nurses (90%) reported some level of experience with administration of long-acting injectable (LAI) antipsychotics, with 24% of nurses administering >10 injections per month. The majority (85%) of nurses surveyed believed that improving adherence would improve patient outcomes. Nearly half (49%) reported that most of their patients depend on a family member or other nonprofessional carer to remind them to take their medication as prescribed. A similar proportion of nurses (43%) reported that most of their patients relied on a professional to remind them to take medication. Most nurses (92%) felt that ensuring continuous medication with LAI antipsychotics would yield long-term benefits for patients, but their opinion was that over a third of patients were unaware of LAI antipsychotic treatments. In a series of forced options, the strategy used most often by respondents (89%) to promote medication adherence was to build trusting relationships with patients while listening to and interpreting their needs and concerns. Respondents also rated this as the most effective strategy that they used (48%). CONCLUSION Nurses are highly aware of adherence issues faced by their patients; further patient education on treatment options is needed.

Schizophrenia through the carers' eyes: results of a European cross-sectional survey. J Psychiatr Ment Health Nurs 2015; 22:472-83.

Abstract
Schizophrenia is a serious mental disorder affecting approximately 29 million people worldwide. The ideal treatment and care of patients with schizophrenia should be provided by a multidisciplinary 'team' involving psychiatrists, nurses and other healthcare professionals, together with carers and patients. In light of the key role carers play in the care of patients with schizophrenia, the present survey was designed to assess the opinions of family members and friends of patients with schizophrenia across Europe and to ascertain their attitudes towards the illness, medication and adherence to medication. Among carers participating in this survey, there was widespread awareness of the issues involved in supporting patients with schizophrenia and the importance of their role in improving poor adherence to medication. Three differences in opinion emerged between the views of carers and psychiatrists; psychiatrists rely more on the patient themselves when assessing adherence than carers would recommend; in contrast to psychiatrists, many carers believe the illness itself contributes to non-adherence; two thirds of carers think that schizophrenia medication damages health (higher than estimated by psychiatrists). The findings from the present survey, taken together with the results from the Adherencia Terapéutica en la Esquizofrenia surveys of psychiatrists and nurses, support the need for a collaborative approach to the issue of treatment nonadherence. In particular, healthcare professionals should recognize the valuable contribution that family carers can make to improve treatment adherence and consequently clinical outcomes for patients with schizophrenia. Schizophrenia carries a significant burden for families providing care. The Adherencia Terapéutica en la Esquizofrenia (ADHES) carers' survey was designed to assess the opinions of family and friends of patients with schizophrenia across Europe and ascertain their attitudes towards the illness, medication and adherence to medication. A questionnaire-based cross-sectional survey of 138 carers across 16 European countries. Interpretation of results was based on a descriptive comparison of responses. Carers recognized the importance of medication to help patients get better (76%) and improve their quality of life (76%) and relationships (74%). Sixty-seven per cent believed medication damages general health. Sixty-five per cent reported that treatment adherence was a burden for patients. Thirty-eight per cent indicated that it was a daily struggle to get patients to take their medication. Fifty per cent perceived that medication administered every few weeks rather than daily was quite/very important. Ninety-three per cent agreed on the importance of family support to boost adherence, with education and information deemed important for families and patients. Carers rely less on the patient themselves when assessing adherence than psychiatrists. The burden faced by carers and patients in taking medication provides an opportunity for healthcare professionals to provide support in a multidisciplinary 'team' involving psychiatrists, nurses and carers.

Abstract
PALMFlexS, a prospective multicentre, open-label, 6-month, phase IIIb interventional study, explored tolerability, safety and treatment response in adults (n = 231) with non-acute but symptomatic schizophrenia switching to flexibly dosed paliperidone palmitate (PP) after unsuccessful treatment with risperidone long-acting injectable therapy (RLAT) or conventional depot antipsychotics (APs). Treatment response was measured by change in Positive and Negative Syndrome Scale (PANSS) total score from baseline (BL) to last-observation-carried-forward (LOCF) endpoint (EP). Safety and tolerability assessments included Extrapyramidal Symptom Rating Scale (ESRS) total score and treatment-emergent adverse events. Significant reductions in mean PANSS total score were observed for all groups (-7.5 to -10.6; p ⩽ 0.01 [BL to LOCF EP]). After switching to PP, more than 50% of all patients achieved ⩾20% and one-third of RLAT-treated patients even achieved ⩾50% improvement in PANSS total score. Across groups, there were significant improvements (p < 0.05) in symptom severity as measured by Clinical Global Impression-Severity (CGI-S; trend for improvement with RLAT; p = 0.0568), subjective well-being, medication satisfaction, and patient functioning with PP. PP was generally well tolerated. Clinically relevant benefits were observed in non-acute patients with schizophrenia switched from RLAT or conventional depot APs to PP.

Abstract
OBJECTIVE This study was designed to explore the efficacy and tolerability of oral paliperidone extended release (ER) in a sample of patients who were switched to flexible doses within the crucial first 5 years after receiving a diagnosis of schizophrenia. METHODS Patients were recruited from 23 countries. Adults with nonacute but symptomatic schizophrenia, previously unsuccessfully treated with other oral antipsychotics, were transitioned to paliperidone ER (3-12 mg/day) and prospectively treated for up to 6 months. The primary efficacy outcome for patients switching for the main reason of lack of efficacy with their previous antipsychotic was at least 20% improvement in Positive and Negative Syndrome Scale (PANSS) total scores. For patients switching for other main reasons, such as lack of tolerability, compliance or 'other', the primary outcome was non-inferiority in efficacy compared with the previous oral antipsychotic. RESULTS For patients switching for the main reason of lack of efficacy, 63.1% achieved an improvement of at least 20% in PANSS total scores from baseline to endpoint. For each reason for switching other than lack of efficacy, efficacy maintenance after switching to paliperidone ER was confirmed. Statistically significant improvement in patient functioning from baseline to endpoint, as assessed by the Personal and Social Performance scale, was observed (p < 0.0001). Treatment satisfaction with prior antipsychotic treatment at baseline was rated 'good' to 'very good' by 16.8% of patients, and at endpoint by 66.0% of patients treated with paliperidone ER. Paliperidone ER was generally well tolerated, with frequently reported treatment-emergent adverse events being insomnia, anxiety and somnolence. CONCLUSIONS Flexibly dosed paliperidone ER was associated with clinically relevant symptomatic and functional improvement in recently diagnosed patients with non-acute schizophrenia previously unsuccessfully treated with other oral antipsychotics.

Abstract
In this prospective multicentre, open-label, 6-month study (Paliperidone Palmitate Flexible Dosing in Schizophrenia [PALMFlexS]), tolerability, safety and treatment response with paliperidone palmitate (PP) were explored in patients with acute symptoms of schizophrenia following switching from previously unsuccessful treatment with oral antipsychotics. This pragmatic study was conducted in a large, more representative sample of the general schizophrenia population compared to randomized controlled pivotal trials, to specifically mimic real-world clinical situations. After initiation on Day 1 and Day 8, patients received PP once monthly at flexible doses (50-150mgeq.) intramuscularly. The primary efficacy outcome was defined as the percentage of patients achieving ≥30% improvement in PANSS total score from baseline (BL) to last-observation-carried-forward (LOCF) endpoint (EP). Safety and tolerability assessments included Extrapyramidal Symptom Rating Scale (ESRS) total score and treatment-emergent adverse events (TEAEs). Overall, 212 patients received PP at least once after switching from oral antipsychotics, primarily due to lack of efficacy (45.8%). Significant improvements from BL in mean (SD) PANSS total score were observed from Day 8 onwards (BL to LOCF EP: -31.0 [29.0]; p<0.0001). At endpoint, two-thirds (66.7%) and 43.5% of patients achieved a ≥30% and ≥50% improvement in mean PANSS total score, respectively. PP was associated with significant improvements across secondary measures of symptom severity, subjective well-being, medication satisfaction, illness-related disorders of activity and participation, and patient functioning (p<0.0001; BL to LOCF EP). PP was generally well tolerated, with significant reductions in ESRS total score (p<0.0001) and mainly mild-to-moderate TEAEs. TEAEs reported in ≥5% of patients were injection-site pain (13.7%), insomnia (10.8%), psychotic disorder (10.4%), headache and anxiety (both 6.1%). The PALMFlexS study findings provide valuable pragmatic clinical data on PP treatment in patients with acute schizophrenia previously unsuccessfully treated with oral antipsychotics.

Abstract
OBJECTIVE To explore differences in outcomes for patients with schizophrenia treated with risperidone long-acting treatment (RLAT) or oral antipsychotics (oAP). METHODS The International Observational Registry on Schizophrenia (InORS) explored flexible doses of newly initiated RLAT and oAPs for adults with schizophrenia, exploring 6-month retrospective hospitalization data and 12-month prospective medication use, outcomes, and tolerability. Efficacy outcomes included hospitalizations, the Clinical Global Impression of Schizophrenia (CGI-SCH), and the Global Assessment of Functioning (GAF). Medication switch patterns were also analysed. RESULTS Data were analysed from 1083 patients (561 RLAT, 522 oAP). At baseline, RLAT patients had higher symptom severity, greater functional impairment, and poorer compliance. Percentages of patients hospitalized were similar between groups, and median duration per hospitalization decreased after RLAT initiation and with oAP. The difference in duration of hospitalization between the retrospective and prospective period was significantly better with RLAT (P = 0.002). Mean CGI-SCH change from baseline was significantly better for RLAT vs. oAP patients for overall, positive, and negative symptom scores (P < 0.05). Mean functional improvement from baseline was significantly higher with RLAT vs. oAP (P < 0.001). CONCLUSIONS Hospitalizations and symptomatic and functional outcomes were better with RLAT vs. oAP; frequent medication switches were associated with less favourable outcomes.

Abstract
OBJECTIVE To document prescribing patterns in clinical practice and assess long-term outcomes related to initiation of paliperidone ER and other oral antipsychotics among patients with schizophrenia in a naturalistic setting. RESEARCH DESIGN AND METHODS An international, non-interventional, naturalistic study of adult patients (≥18 years) with schizophrenia. Patients were assigned to the relevant treatment group (paliperidone ER or 'all other oral antipsychotics') after switching to, or initiating, oral antipsychotic treatment. Retrospective 12 month data collection was followed by 12 month prospective data collection, with 3-monthly assessments. The primary endpoint was time to all-cause discontinuation of new medication. Secondary endpoints included Clinical Global Impression-Severity (CGI-S) score, Clinical Global Impression-Schizophrenia (CGI-SCH) score, Personal and Social Performance (PSP) score, health-related quality of life (HR-QoL) and quality of sleep, evaluation of healthcare resource utilization and patient's treatment satisfaction. RESULTS A total of 4051 patients were included in the intent-to-treat (ITT) analysis set. All-cause study discontinuation rates were comparable between the paliperidone ER group (16.8%) and the 'all other oral antipsychotics' group (15.5%). There was no difference in the time to discontinuation of newly initiated antipsychotic treatments between paliperidone ER and 'all other oral antipsychotics' groups. Paliperidone ER was associated with greater improvements from baseline to endpoint in both the PSP scale score (+14.2 vs +13.1, p = 0.041) and the physical component of quality of life (SF-12 Physical scores; +3.9 vs +2.9, p = 0.003) compared to 'all other oral antipsychotics'. Improvements in mean CGI-S score, CGI-SCH score, HR-QoL, quality of sleep and daytime drowsiness, as well as patients' treatment satisfaction were comparable between treatment groups. The incidence of adverse events was comparable between groups. CONCLUSIONS This study provides valuable data on the prescribing habits and treatment outcomes associated with use of paliperidone ER in everyday clinical practice, and supports previous findings of the favorable functional improvement and treatment satisfaction associated with paliperidone ER.

Dosing and switching of paliperidone ER in patients with schizophrenia: recommendations for clinical practice. Ann Gen Psychiatry 2014; 13:10.

Abstract
Many patients with schizophrenia receive long-term treatment with antipsychotic medication. Switching of antipsychotic medication due to lack of efficacy, tolerability issues, and partial/non-adherence is common. Despite this, consensus strategies for switching between antipsychotics are lacking. This manuscript provides practical recommendations for switching antipsychotic medication to ensure optimal management of patients with schizophrenia, with a particular focus on paliperidone extended release (ER). The authors drew on their clinical experience supported by detailed discussion of literature describing antipsychotic switching techniques and strategies and findings from paliperidone ER clinical trials. Antipsychotic switching strategies should be individualized and take into consideration the pharmacokinetic (PK) and pharmacodynamic (PD) properties of the pre- and post-switch medication. The use of temporary concomitant medications may be appropriate in some scenarios. Abrupt withdrawal of pre-switch medication may be appropriate in some instances but carries a greater risk of rebound and withdrawal symptoms than other strategies. Cross-tapering is the method most widely used in clinical practice. Paliperidone ER can be initiated without dose titration. The EU SmPC recommended dose of paliperidone ER is 6 mg/day; but doses should be individualized within the approved range of 3-12 mg/day. Higher doses may be required due to insufficient efficacy of the previous antipsychotic or in patients with acute symptoms. Recently diagnosed patients, those with renal impairment, or patients who have previously experienced tolerability issues with other antipsychotics may require lower doses. When switching from risperidone, higher doses of paliperidone ER may be required compared with risperidone. When switching from antipsychotics that have sedative and/or significant anticholinergic activity, the pre-switch antipsychotic should be tapered off gradually. Antipsychotics with less sedating and little anticholinergic activity can be tapered off over a shorter period. Temporary concomitant sedative medication may be beneficial when switching from antipsychotics with relatively higher sedative propensities. Switching from another antipsychotic to paliperidone ER requires individualized switching strategies and dosing, dependent on the characteristics of the patient and the PK and PD properties of the pre-switch medication. Cross-tapering strategies should be considered as a means of reducing the risk of rebound and withdrawal symptoms.

Abstract
OBJECTIVE This study explores relevant outcomes with flexibly dosed paliperidone extended-release (ER) in a real-world design. RESEARCH DESIGN AND METHODS Patients were recruited from 23 countries. Adults with non-acute schizophrenia (n = 1812), previously unsuccessfully treated with other oral antipsychotics, were transitioned to paliperidone ER and prospectively treated for 6 months. MAIN OUTCOME MEASURES Primary efficacy outcome for patients switching for the main reason of lack of efficacy was ≥ 20% improvement in Positive and Negative Syndrome Scale (PANSS) total scores. For patients switching for main reasons other than lack of efficacy, primary outcome was non-inferiority in efficacy compared with the previous medication. RESULTS Among the lack-of-efficacy group, 61% achieved a ≥ 20% improvement in PANSS total scores from baseline to endpoint. For switchers from other than the lack-of-efficacy group, efficacy maintenance after switching to paliperidone ER was confirmed. Clinically relevant and statistically significant symptomatic improvements occurred for each patient group based on main reason for switching. CONCLUSION Paliperidone ER was well tolerated and associated with a meaningful clinical response in patients who switched from other oral antipsychotics, with insomnia and anxiety as most frequent side-effects.

ObjectifsÉvaluer la tolérance, la sécurité d’emploi et l’efficacité de doses flexibles de PP chez des patients adultes en période d’exacerbation aiguë d’une schizophrénie, après échec d’un traitement par antipsychotiques oraux.MéthodesÉtude internationale, prospective, ouverte, de six mois.Critères d’évaluationPositive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Severity (CGI-S), événements indésirables (EI), changement de poids.RésultatsDeux cent douze patients (population en intention de traiter) : âge moyen 36,4 ± 12,1 ans, 59,0 % d’hommes, 85,4 % souffrant de schizophrénie paranoïde ont été inclus. La principale raison de la substitution d’un antipsychotique oral par le PP était un manque d’efficacité (45,8 %). 70,3 % des patients ont terminé l’étude de six mois. Les raisons les plus fréquentes d’arrêt précoce ont été : le choix du patient (9,4 %), des EI (9,0 %), les perdus de vue (4,7 %), le manque d’efficacité (2,8 %). Le score total moyen à la PANSS initiale (98,5 ± 20,1) a diminué, et ce dès j8, pour atteindre 67,4 ± 24,0 à la fin de l’étude (diminution de −31,0 ± 29,0, p < 0,0001). 66,7 % des patients ont eu une amélioration de plus de 30 % du score PANSS total et le pourcentage de patients jugés manifestement malades ou pire (CGI-S) a diminué de 75,1 % à 20,5 %. Les EIs (≥ 5 % patients) : douleur au site d’injection (13,7 %), insomnie (10,8 %), trouble psychotique (10,4 %), céphalées (6,1 %) et anxiété (6,1 %). Le changement moyen de poids a été de 2,6 ± 5,6 kg (IC 95 % [1,8; 3,4]).ConclusionsCes résultats confirment que le PP à doses flexibles est bien toléré et permet une réponse clinique précoce et cliniquement significative chez des patients en période d’exacerbation aiguë de leur trouble schizophrénique, après échec d’un traitement par antipsychotiques oraux.

Definitions and drivers of relapse in patients with schizophrenia: a systematic literature review. Ann Gen Psychiatry 2013; 12:32. [PMID: 24148707 PMCID: PMC4015712 DOI: 10.1186/1744-859x-12-32] [Citation(s) in RCA: 164] [Impact Index Per Article: 14.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2012] [Accepted: 10/07/2013] [Indexed: 11/11/2022] Open
Abstract
Relapse in patients with schizophrenia has devastating repercussions, including worsening symptoms, impaired functioning, cognitive deterioration and reduced quality of life. This progressive decline exacerbates the burden of illness on patients and their families. Relapse prevention is identified as a key therapeutic aim; however, the absence of widely accepted relapse definition criteria considerably hampers achieving this goal. We conducted a literature review in order to investigate the reporting of relapses and the validity of hospitalization as a proxy for relapse in patients with schizophrenia. The primary aim was to assess the range and validity of methods used to define relapse in observational or naturalistic settings. The secondary aim was to capture information on factors that predicted or influenced the risk of relapse. A structured search of the PubMed database identified articles that discussed relapse, and hospitalization as a proxy of relapse, in patients with schizophrenia. National and international guidelines were also reviewed. Of the 150 publications and guidelines identified, 87 defined relapse and 62% of these discussed hospitalization. Where hospitalization was discussed, this was as a proxy for, or a component of, relapse in the majority of cases. However, hospitalization duration and type varied and were not always well defined. Scales were used to define relapse in 53 instances; 10 different scales were used and multiple scales often appeared within the same definition. There were 95 references to factors that may drive relapse, including non-adherence to antipsychotic medication (21/95), stress/depression (11/95) and substance abuse (9/95). Twenty-five publications discussed the potential of antipsychotic therapy to reduce relapse rates-continuous antipsychotic therapy was associated with reduced frequency and duration of hospitalization. Non-pharmacological interventions, such as psychoeducation and cognitive behavioural therapy, were also commonly reported as factors that may reduce relapse. In conclusion, this review identified numerous factors used to define relapse. Hospitalization was the factor most frequently used and represents a useful proxy for relapse when reporting in a naturalistic setting. Several factors were reported to increase the risk of relapse, and observation of these may aid the identification of at-risk patients.

Abstract
OBJECTIVE The objective of this study was to report the long-term remission results from the ConstaTRE relapse prevention trial, in which clinically stable adults with schizophrenia or schizoaffective disorder treated with oral risperidone, olanzapine, or oral conventional antipsychotics were randomized to risperidone long-acting injectable (RLAI) or oral quetiapine, dosed according to package-insert recommendations. METHODS In the ConstaTRE trial, efficacy and tolerability were recorded for up to 24 months. This post hoc analysis presents remission data, defined, according to the Schizophrenia Working Group criteria, as achieving and maintaining eight core symptoms of schizophrenia that are mild or less over 6 months. Additional secondary outcome measures are also presented. RESULTS A total of 710 patients were randomized to RLAI (n = 355) or quetiapine (n = 355). Mean mode ± standard deviation (SD) drug doses were RLAI 33 ± 10 mg every 2 weeks and quetiapine 413 ± 159 mg daily. Full remission was achieved by 51.1% of patients with RLAI and 39.3% with quetiapine (p = 0.003). Mean ± SD of full remission durations were not significantly different with RLAI (540 ± 181 days) and quetiapine (508 ± 188 days). Overall tolerability was similar between treatment groups. CONCLUSIONS Among stable patients with schizophrenia or schizoaffective disorder, remission was more likely after switching to RLAI than quetiapine.

Differential proteomic analysis of abnormal intramyoplasmic aggregates in desminopathy. J Proteomics 2013; 90:14-27.

Abstract
UNLABELLED Desminopathy is a subtype of myofibrillar myopathy caused by desmin mutations and characterized by protein aggregates accumulating in muscle fibers. The aim of this study was to assess the protein composition of these aggregates. Aggregates and intact myofiber sections were obtained from skeletal muscle biopsies of five desminopathy patients by laser microdissection and analyzed by a label-free spectral count-based proteomic approach. We identified 397 proteins with 22 showing significantly higher spectral indices in aggregates (ratio >1.8, p<0.05). Fifteen of these proteins not previously reported as specific aggregate components provide new insights regarding pathomechanisms of desminopathy. Results of proteomic analysis were supported by immunolocalization studies and parallel reaction monitoring. Three mutant desmin variants were detected directly on the protein level as components of the aggregates, suggesting their direct involvement in aggregate-formation and demonstrating for the first time that proteomic analysis can be used for direct identification of a disease-causing mutation in myofibrillar myopathy. Comparison of the proteomic results in desminopathy with our previous analysis of aggregate composition in filaminopathy, another myofibrillar myopathy subtype, allows to determine subtype-specific proteomic profile that facilitates identification of the specific disorder. BIOLOGICAL SIGNIFICANCE Our proteomic analysis provides essential new insights in the composition of pathological protein aggregates in skeletal muscle fibers of desminopathy patients. The results contribute to a better understanding of pathomechanisms in myofibrillar myopathies and provide the basis for hypothesis-driven studies. The detection of specific proteomic profiles in different myofibrillar myopathy subtypes indicates that proteomic analysis may become a useful tool in differential diagnosis of protein aggregate myopathies.

Psychiatrists' perceptions of the clinical importance, assessment and management of patient functioning in schizophrenia in Europe, the Middle East and Africa. Ann Gen Psychiatry 2013; 12:8. [PMID: 23531356 PMCID: PMC3778848 DOI: 10.1186/1744-859x-12-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2013] [Accepted: 02/27/2013] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND It has been estimated that as many as two thirds of patients with schizophrenia are unable to perform basic personal and social roles or activities. Occupational functioning and social functioning, as well as independent living, are considered as core domains of patient functioning. Improvement in patient functioning has also been recognized as an important treatment goal in guidelines and an important outcome by regulatory agencies. Nevertheless, information is lacking on how these aspects are being considered by psychiatrists across the world and how they are being assessed and managed. METHODS The 'Europe, the Middle East and Africa functioning survey' was designed to canvas opinions of psychiatrists across these regions to ascertain their perceptions of the clinical importance, assessment and management of functioning amongst their patients with schizophrenia. The survey comprised 17 questions and was conducted from March to April 2011 in 42 countries. Data collected included the demographics of respondents and their opinions regarding personal and social functioning in patients with schizophrenia. RESULTS Results were obtained from 4,163 clinicians. Psychiatrists estimated that more than two thirds (70%) of their patients with schizophrenia showed impaired or very poor levels of functioning. The majority of psychiatrists (92%) believed that personal and social functioning was an important treatment goal for patients with schizophrenia, and 91% believed it was an important goal for patients' families. The majority of psychiatrists (55%) assess the personal and social functioning of their patient at each visit; however, 81% reported that they determine the level of functioning through clinical interview and not by using a specific assessment scale. To manage personal and social functioning in their patients, 26% of psychiatrists prefer pharmacological interventions, whereas 46% prefer psychosocial interventions. CONCLUSION Psychiatrists recognize that functioning is impaired/very poor in patients with schizophrenia, and there is still an important need to address functioning as a main treatment goal for patients with schizophrenia.

Attitudes towards the administration of long-acting antipsychotics: a survey of physicians and nurses. BMC Psychiatry 2013; 13:58.

Abstract
BACKGROUND Discontinuation of antipsychotic treatment for schizophrenia can interrupt improvement and exacerbate the illness. Reasons for discontinuing treatment are multifactorial and include adherence, efficacy and tolerability issues. Poor adherence may be addressed through non-pharmacological approaches as well as through pharmacological ones, ie ensured delivery of medication, such as that achieved with long-acting injectable (LAI) antipsychotics. However, attitudes of healthcare professionals (HCPs) towards LAI antipsychotics may influence their prescribing decisions and may influence medication choices offered to patients. We therefore conducted a survey to investigate factors driving LAI use as well as physician and nurse attitudes to LAI antipsychotics and to different injection sites. METHODS An independent market research agency conducted the survey of HCPs across Europe. Participants were recruited by telephone and completed the survey online. Using conjoint analyses (a multivariate statistical technique analysing preferences on the basis of ranking a limited number of attributes which are presented repetitively), attitudes to oral versus LAI medication and gluteal versus deltoid injection routes were assessed. RESULTS A total of 891 HCPs across Europe were surveyed. Of these, 40% would choose LAI antipsychotics for first episode patients whereas 90% would select LAI antipsychotics for chronic patients with two to five psychotic episodes. Dominant elements in antipsychotic choice were low sedation but no tardive dyskinesia, no or mild pain at injection and low risk of embarrassment or impact upon therapeutic alliance. Eighty-six per cent of respondents considered that having the choice of a deltoid as well as gluteal administration site was beneficial over not having that choice. Two thirds of respondents said they agreed that medication administration via the deltoid muscle may reduce social embarrassment associated with LAI antipsychotics and most respondents (61%) believed that administration of LAI antipsychotics into the deltoid muscle as opposed to the gluteal muscle may be more respectful to the patient. CONCLUSIONS In this survey of physicians and nurses, attitudes towards LAI antipsychotics compared with oral medication were generally positive. Respondents considered that the availability of a deltoid administration route would offer increased choice in LAI antipsychotic administration and may be perceived as more respectful and less socially embarrassing.

Abstract
The EC (European Council) Directive on radiation protection of patients requires that criteria for acceptability of equipment in diagnostic radiology, nuclear medicine and radiotherapy be established throughout the member states. This study reviews the background to this requirement and to its implementation in practice. It notes and considers parallel requirements in the EC medical devices directive and International Electrotechnical Commission standards that it is also important to consider and that both sets of requirements should ideally be harmonised due to the global nature of the equipment industry. The study further reviews the types of criteria that can be well applied for the above purposes, and defines qualitative criteria and suspension levels suitable for application. Both are defined and relationships with other acceptance processes are considered (including acceptance testing at the time of purchase, commissioning and the issue of second-hand equipment). Suspension levels are divided into four types, A, B, C and D, depending on the quality of evidence and consensus they are based on. Exceptional situations involving, for example, new or rapidly evolving technology are also considered. The publication and paper focuses on the role of the holder of the equipment and related staff, particularly the medical physics expert and the practitioner. Advice on how the criteria should be created and implemented is provided for these groups and how this might be coordinated with the supplier. Additional advice on the role of the regulator is provided.

Abstract
BACKGROUND Nonadherence is common among patients with schizophrenia, although the rates vary according to means of assessment and patient population. Failure to adhere to medication can have a major impact on the course of illness and treatment outcomes, including increasing the risk of relapse and rehospitalization. Understanding psychiatrists' perception of the causes and consequences of nonadherence is crucial to addressing adherence problems effectively. METHODS The Europe, the Middle East, and Africa (EMEA) Spanish Adherencia Terapéutica en la Esquizofrenia (ADHES) survey was conducted by questionnaire during January-March 2010 among psychiatrists treating patients with schizophrenia in 36 countries. The survey comprised 20 questions. In addition to recording the demographic details of the 4722 respondents (~12% response rate), it canvassed their preferred methods of assessing adherence, their perceptions of adherence rates, reasons for nonadherence, and strategies to improve adherence. RESULTS Psychiatrists estimated that 53% of their patients with schizophrenia were partially/nonadherent during the previous month. They estimated only one-third of patients who deteriorated after stopping medication were able to attribute this to nonadherence. Psychiatrists assessed adherence most often by patient interview. Lack of insight was viewed as the most important cause of medication discontinuation, followed by patients feeling better and thinking their medication unnecessary, and experiencing undesirable side effects. Considerably fewer psychiatrists viewed insufficient efficacy, cognitive impairment, or drug/alcohol abuse as the most important reasons for their patients stopping medication. CONCLUSION Psychiatrists throughout EMEA recognize the impact of partial/nonadherence to medication, with patient enquiry being the most commonly used means of assessment. There remains a need for more proactive management of patients with schizophrenia, particularly in increasing patient insight of their illness in order to improve adherence and minimize the consequences of relapse. Strategies focused on raising awareness of the importance of adherence are also warranted, with the aim of improving patient outcomes in schizophrenia.
