RESUMO
Psychiatric emergencies occur frequently in the community setting, e.g. the patient's home or public places. Little is known about the characteristics and outcome of these situations. This study describes psychiatric emergencies in the canton of Zurich, Switzerland, and examines determinants of their outcome. We retrospectively analyzed 620 medical records of consultations classified as psychiatric emergencies of a 24/7 service of community-based emergency physicians. Information on sociodemographic, clinical and situational factors was extracted. The observation period was 6 months in 2017. Binary logistic regression was used to examine predictors for involuntary admissions. Most emergency consultations (64.5%) took place at the patient's home, followed by police stations (31.0%), public places (3.2%), and somatic hospitals (1.3%). Patient characteristics and reasons for consultation varied considerably between the locations. The first involved person was commonly a relative. Of all consultations, 38.4% resulted in involuntary admissions, mainly in patients with psychosis, suicidality, aggression, refusal of necessary treatment and previous involuntary admissions. Situation-related factors and the involvement of relatives were no significant predictors of the outcome. Psychiatric emergencies occur in different places and in patients with a variety of psychiatric symptoms. Although half of the emergency situations were resolved in the community, the rate of involuntary admissions was still high. For additional reduction, the further development of quickly available alternatives to psychiatric inpatient treatment is required. These should be specifically geared towards acute situations in patients with the described risk factors. Additionally, the role of relatives during psychiatric emergencies should be further studied.

BACKGROUND: In psychiatric treatment containment measures are used to de-escalate high-risk situations. These measures can be characterized by their immanent amount of coercion. Previous research could show that the attitudes towards different containment measures vary throughout countries. The aim of this study was to compare the attitudes towards containment measures between three study sites in Switzerland which differ in their clinic traditions and policies and their actual usage of these measures. METHODS: We used the Attitude to Containment Measures Questionnaire (ACMQ) in three psychiatric hospitals in Switzerland (Zurich, Muensingen and Monthey) in patients, their next of kin (NOK) and health care professionals (HCP). Furthermore, we assessed the cultural specifics and rates of coercive measures for these three hospitals. RESULTS: We found substantial differences in the usage of and the attitudes towards some containment measures between the three study sites. The study site accounted for a variance of nearly zero in as needed medication to 15% in seclusion. The differences between study sites were bigger in the HCPs' attitudes (up to 50% of the variance), compared to NOK and patients. In the latter the study site accounted for up to 6% of the variance. The usage/personal experience of containment measures in general was associated with higher agreement. CONCLUSIONS: Although being situated in the same country, there are substantial differences in the rates of containment measures between the three study sites. We showed that the HCP's attitudes are more associated with the clinic traditions and policies compared to patients' and their NOKs' attitudes. One can conclude that patients' preferences depend less on clinic traditions and policies. Therefore, it is important to adapt treatment to the individual patients' attitudes. TRIAL REGISTRATION: The study was reviewed and approved by the Cantonal Ethics Commission of Zurich, Switzerland (Ref.-No. EK: 2016-01526, decision on 28.09.2016) and the Cantonal Ethics Commission of Bern, Switzerland (Ref.-Nr. KEK-BE: 2015-00074). This study has been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. The permission for conduction of the study was granted by the medical directors at the three study sites. The authors informed the respondents (patients, NOK, HCP) of their rights in the study in an oral presentation and/or a cover letter. They assured the participants of the confidentiality and anonymity of the data, and the voluntariness of participation. Patients were given an information sheet with the possibility to consent in the conduction of the study. Return of the completed questionnaires from HCP and NOK was constituted as confirmation of their consent. No identifying factors were collected to ensure privacy. This article does not contain any studies with animals performed by any of the authors.

BACKGROUND: Studies have identified multiple risk factors for development of cognitive decline after surgery. Impaired cerebrovascular autoregulation may be a contributor to postoperative cognitive decline. METHODS: One hundred and forty patients admitted for major elective noncardiac surgery were recruited. Near-infrared spectroscopy was used to calculate the tissue oxygenation index of dynamic autoregulation (TOx). The primary endpoint was Day 3 cognitive recovery as assessed using the Postoperative Quality of Recovery Scale. The secondary endpoint was a combined major adverse event of death, acute myocardial infarction, cardiac arrest, stroke, pulmonary embolism, sepsis, and acute kidney injury at Day 30. RESULTS: Higher optimal TOx values, signifying impaired autoregulation, were associated with worse outcomes. Patients who cognitively recovered at Day 3 (n = 47) had lower optimal TOx values (TOxopt ) than patients who did not recover (n = 22): 0.06 (0.24) vs 0.18 (0.16) (mean [SD]), P = 0.02. Patients who did not suffer a major adverse event (n = 102) had lower TOxopt than patients who did (n = 17): 0.09 (0.21) vs 0.20 (0.27), P = 0.04. When dichotomized as having impaired or intact autoregulation based on TOxopt levels, a value of TOxopt ≥0.1 correctly identified 72.7% of patients who did not cognitively recover, OR 3.3 (1.1-9.9) (Odds ratio, [95% CI]), P = 0.03. TOxopt ≥0.1 correctly identified 82.4% of patients who suffered a major adverse event, OR 4.7 (1.3-17.2), P = 0.02. CONCLUSIONS: In older and higher risk patients having major noncardiac surgery, impaired cerebrovascular autoregulation was associated with failure of cognitive recovery in the early postoperative period and with 1-month mortality and morbidity.

BACKGROUND: Cerebrovascular autoregulation can be continuously monitored from slow fluctuations of arterial blood pressure (ABP) and regional cerebral oxygen saturation (rSO2). The purpose of this study was to evaluate the index of dynamic cerebrovascular autoregulation (TOx) and the associated 'optimal' ABP in normal adult healthy subjects. METHODS: Twenty-eight healthy volunteers were studied. TOx was calculated as the moving correlation coefficient between spontaneous fluctuations of ABP and rSO2. ABP was measured with the Finometer photoplethysmograph. The ABP with optimal autoregulation (ABPOPT) was also determined as the ABP level with the lowest associated TOx (opt-TOx). RESULTS: Average rSO2 and TOx was 72.3 ± 2.9% and 0.05 ± 0.18, respectively. Two subjects had impaired autoregulation with a TOx > 0.3. The opt-TOx was - 0.1 ± 0.26. ABPOPT was 87.0 ± 16.7 mmHg. The difference between ABP and ABPOPT was - 0.3 ± 7.5 mmHg. In total, 44% of subjects had a deviation of ABP from ABPOPT exceeding 5 mmHg. ABPOPT ranged from 57 to 117 mmHg. CONCLUSIONS: TOx in healthy volunteers on average displays intact autoregulation and ABP close to ABPOPT. However, some subjects have possible autoregulatory dysfunction or a significant deviation of ABP from ABPOPT, which may confer a susceptibility to neurological injury.

Treatment pressure restricts patients' voluntary and autonomous decisions. Yet interventions involving treatment pressure are widely used in mental health and psychosocial services. This cross-sectional study explored whether mental health professionals' knowledge on five types of treatment pressure (no coercion, persuasion or conviction, leverage, threat, and formal coercion) was associated with sociodemographic, professional and contextual factors. A more positive attitude towards interventions involving treatment pressure was associated with underrating the level of those interventions compared with a predefined default value. The treatment setting and professional group played a minor role in 'leverage' and 'formal coercion' types of treatment pressure, respectively.

Although involuntary commitment (IC) is a serious intervention in psychiatry and must always be regarded as an emergency measure, the knowledge about influencing factors is limited. Aims were to test the hypothesis that duration of involuntary hospitalization and associated parameters differ for IC's mandated by physicians with or with less routine experience in psychiatric emergency situations. Duration of involuntary hospitalization and duration until day-passes of 508 patients with IC at the University Hospital of Psychiatry Zurich were analyzed using a generalized linear model. Durations of involuntary hospitalization and time until day-passes were significantly shorter in patients referred by physicians with less routine experience in psychiatric emergency situations than compared to experienced physicians. Shorter hospitalizations following IC by less-experienced physicians suggest that some IC's might be unnecessary. A specific training or restriction to physicians being capable of conducting IC could decrease the rate of IC.

BACKGROUND: The goal was to investigate the quality in terms of formal and content-based comprehensiveness of the forms for involuntary admission before and after the introduction of the new law (KESR, "Kindes- und Erwachsenenschutzrecht") for the regulation of involuntary admission. Moreover, the study aimed at assessing if the quality of the admission forms was associated with the professional qualifications of the professionals ordering them. Finally, the patients were characterized. METHODS: Retrospective evaluation of all commitment reports at the University Hospital of Psychiatry within a six month period before and after the introduction the KESR (N(2012) = 489; N(2013) = 651). Formal and content-related criteria for the commitment certificates were recorded as well as the socio-demographic and clinical data of the cases admitted. There were no exclusion criteria. The data was descriptively evaluated, formal and content-based criteria were compared between groups of admitting professionals. The Chi-Square-Test following Pearson and T-Test were used to test for group differences. RESULTS: Formal and content-related quality criteria deficiencies were noted. The best-documented forms came from psychiatrists and emergency physicians, followed by general practitioners and hospital doctors. There have been improvements in the quality of the documents since the new KESR within all professional subsamples. CONCLUSIONS: Psychiatrists and those who regularly deal with emergency commitments were likely to issue forms of high quality. Due to the considerable consequences associated with involuntary admission for affected individuals, their relatives and also professionals, the considerable deficits in the quality of the documentation must be intensively addressed in training, advanced training, continuing education and in daily routines.

BACKGROUND: Near infrared spectroscopy (NIRS) enables continuous monitoring of dynamic cerebrovascular autoregulation, but this methodology relies on invasive blood pressure monitoring (iABP). We evaluated the agreement between a NIRS based autoregulation index calculated from invasive blood pressure monitoring, and an entirely non-invasively derived autoregulation index from continuous non-invasive blood pressure monitoring (nABP) using the Finometer photoplethysmograph. METHODS: Autoregulation was calculated as the moving correlation coefficient between iABP and rSO2 (iTOx) or nABP and rSO2 (nTOx). The blood pressure range where autoregulation is optimal was also determined for invasive (iABPOPT) and non-invasive blood pressure measurements (nABPOPT). RESULTS: 102 simultaneous bilateral measurements of iTOx and nTOx were performed in 19 patients (median 2 per patient, range 1-9) with different acute pathologies (sepsis, cardiac arrest, head injury, stroke). Average iTOx was 0.01 ± 0.13 and nTOx was 0.01 ± 0.11. The correlation between iTOx and nTOx was r = 0.87, p < 0.001, 95 % agreement ± 0.12, bias = 0.005. The interhemispheric asymmetry of autoregulation was similarly assessed with iTOx and nTOx (r = 0.81, p < 0.001). Correlation between iABPOPT and nABPOPT was r = 0.47, p = 0.003, 95 % agreement ± 32.1 mmHg, bias = 5.8 mmHg. Coherence in the low frequency spectrum between iABP and nABP was 0.86 ± 0.08 and gain was 1.32 ± 0.77. CONCLUSIONS: The results suggest that dynamic cerebrovascular autoregulation can be continuously assessed entirely non-invasively using nTOx. This allows for autoregulation assessment using spontaneous blood pressure fluctuations in conditions where iABP is not routinely monitored. The nABPOPT might deviate from iABPOPT, likely because of discordance between absolute nABP and iABP readings.

BACKGROUND: Evaluations of the recovery orientation of mental health services have focused on outpatient and rehabilitative rather than acute inpatient facilities. AIM: This naturalistic observational study seeks to evaluate the subjective perspective and functional outcome of inpatients before and after structural alterations. The changes made were the introduction of treatment conferences and conjoint treatment planning, reduction of the total time spent on reports about patients (in their absence), and recovery-oriented staff training on an acute psychiatric unit of the University Hospital of Psychiatry, Zurich, Switzerland. METHODS: During 1 year (2011/2012) eligible patients on the study unit were interviewed on a voluntary basis using established instruments to assess several recovery-relevant aspects. Two different samples (before and after the project; n = 34 and n = 29) were compared with regard to subjective parameters (e.g. patients' attitudes toward recovery, quality of life, perceived coercion, treatment satisfaction, and hope), clinical and socio-demographic basic data, as well as the functional outcome according to the Health of the Nation Outcome Scales (HoNOS). RESULTS: Some patient attitudes towards recovery and their self-assessment of the recovery process improved during the study. Other subjective parameters remained stable between samples. Functional outcome was better in subjects who were treated after the implementation of the new concept. The length of stay remained unchanged. CONCLUSIONS: The implementation of recovery-oriented structures and providing the necessary theoretical underpinning on an acute psychiatric unit is feasible and can have an impact on attitudes and knowledge of personal recovery.

To evaluate professionals' attitudes to recovery and coercion, as well their satisfaction with working conditions before and after the implementation of a recovery-oriented ward concept on an admission ward. Longitudinal study design with two measurement times of the study sample, with a control group assessed at study end. Evaluating the implementation of the recovery concept, attitudes towards recovery, coercion, perceptions of the ward and working satisfaction were assessed with questionnaires and computed using Chi square and ANOVA variance analyses. The members of the intervention ward (n = 17) did not differ from the control group (n = 21), except that control group members were younger. The recovery-orientation of the study ward (ROSE questionnaire) increased significantly (alpha level = 0.05) from study begin to study end (p = 0.003), and compared to the control group (p = 0.002). The attitudes towards coercion did not change significantly in the intervention group, but did so compared to the control group. The contentedness (GMI) and the satisfaction with working conditions (ABB) of the intervention group members compared to control group was significantly higher (GMI: p = 0.004, ABB subscale working conditions: p = 0.043, satisfaction: p = 0.023). The study indicates that recovery-oriented principles can be implemented even in an acute admission ward, increasing team satisfaction with work, while attitudes towards coercion did not change significantly within this single-unit project.

BACKGROUND: To investigate the relationship between cerebrovascular pressure reactivity and cerebral oxygen regulation after head injury. METHODS: Continuous monitoring of the partial pressure of brain tissue oxygen (PbrO2), mean arterial blood pressure (MAP), and intracranial pressure (ICP) in 11 patients. The cerebrovascular pressure reactivity index (PRx) was calculated as the moving correlation coefficient between MAP and ICP. For assessment of the cerebral oxygen regulation system a brain tissue oxygen response (TOR) was calculated, where the response of PbrO2 to an increase of the arterial oxygen through ventilation with 100 % oxygen for 15 min is tested. Arterial blood gas analysis was performed before and after changing ventilator settings. RESULTS: Arterial oxygen increased from 108 ± 6 mmHg to 494 ± 68 mmHg during ventilation with 100 % oxygen. PbrO2 increased from 28 ± 7 mmHg to 78 ± 29 mmHg, resulting in a mean TOR of 0.48 ± 0.24. Mean PRx was 0.05 ± 0.22. The correlation between PRx and TOR was r = 0.69, P = 0.019. The correlation of PRx and TOR with the Glasgow outcome scale at 6 months was r = 0.47, P = 0.142; and r = -0.33, P = 0.32, respectively. CONCLUSIONS: The results suggest a strong link between cerebrovascular pressure reactivity and the brain's ability to control for its extracellular oxygen content. Their simultaneous impairment indicates that their common actuating element for cerebral blood flow control, the cerebral resistance vessels, are equally impaired in their ability to regulate for MAP fluctuations and changes in brain oxygen.

BACKGROUND: Involuntary admissions (IA) to psychiatric hospitals are controversial because they interfere with people's autonomy. In some situations, however, they appear to be unavoidable. Interestingly, not all patients perceive the same degree of coercion during IA. The aim of this study was to assess whether the level of knowledge about one's own IA is associated with perceived coercion. METHODS: This multicenter observational study was conducted on n = 224 involuntarily admitted patients. Interviews were conducted at five study centers from April 2021 to November 2021. The Macarthur Admission Experience Survey was administered to assess perceived coercion. Knowledge of involuntary admission, perceptions of information received, and attitudes towards legal aspects of involuntary admission were also assessed. RESULTS: We found that higher levels of knowledge about IA were negatively associated with perceived coercion at admission. Perceived coercion did not differ between study sites. Only half of the patients felt well informed about their IA, and about a quarter found the information they received difficult to understand. DISCUSSION: Legislation in Switzerland requires that patients with IA be informed about the procedure. Strategies to improve patients' understanding of the information given to them about IA might be helpful to reduce perceived coercion, which is known to be associated with negative attitudes towards psychiatry, a disturbed therapeutic relationship, avoidance of psychiatry, and the risk of further coercion.

BACKGROUND AND PURPOSE: The purpose of this study was to investigate the relationship between cerebrovascular autoregulation and outcome after aneurysmal subarachnoid hemorrhage. METHODS: In a prospective observational study, 80 patients after severe subarachnoid hemorrhage were continuously monitored for cerebral perfusion pressure and partial pressure of brain tissue oxygen for an average of 7.9 days (range, 1.9-14.9 days). Autoregulation was assessed using the index of brain tissue oxygen pressure reactivity (ORx), a moving correlation coefficient between cerebral perfusion pressure and partial pressure of brain tissue oxygen. High ORx indicates impaired autoregulation; low ORx signifies intact autoregulation. Outcome was determined at 6 months and dichotomized into favorable (Glasgow Outcome Scale 4-5) and unfavorable outcome (Glasgow Outcome Scale 1-3). RESULTS: Twenty-four patients had a favorable and 56 an unfavorable outcome. In a univariate analysis, there were significant differences in autoregulation (ORx 0.19±0.10 versus 0.37±0.11, P<0.001, for favorable versus unfavorable outcome, respectively), age (44.1±11.0 years versus 54.2±12.1 years, P=0.001), occurrence of delayed cerebral infarction (8% versus 46%, P<0.001), use of coiling (25% versus 54%, P=0.02), partial pressure of brain tissue oxygen (24.9±6.6 mm Hg versus 21.8±6.3 mm Hg, P=0.048), and Fisher grade (P=0.03). In a multivariate analysis, ORx (P<0.001) and age (P=0.003) retained an independent predictive value for outcome. ORx correlated with Glasgow Outcome Scale (r=-0.70, P<0.001). CONCLUSIONS: The status of cerebrovascular autoregulation might be an important pathophysiological factor in the disease process after subarachnoid hemorrhage, because impaired autoregulation was independently associated with an unfavorable outcome.

Meralgia paraesthetica is an entrapment neuropathy of the lateral femoral cutaneous nerve, usually due to compression at the inguinal ligament as the nerve passes from the pelvis into the thigh. Surgical decompression of the lateral femoral cutaneous nerve is a simple and effective treatment option, but the surgical anatomy of the area is not always familiar to neurosurgeons and neurosurgical trainees alike. This paper is a simple review of the relevant surgical anatomy and the surgical steps of lateral femoral cutaneous nerve decompression, with the aim of providing the busy surgeon and trainee a quick and easy reference guide to the procedure.

BACKGROUND: Relatively few studies have examined how patients with schizophrenia and depression view psychiatric research and what influences their readiness to participate. METHODS: A total of 763 patients (48% schizophrenia, 52% depression) from 7 European countries were examined using a specifically designed self-report questionnaire ["Hamburg Attitudes to Psychiatric Research Questionnaire" (HAPRQ)]. RESULTS: Most patients (98%) approved of psychiatric research, in general, at least "a little". There was a tendency to approve psychosocial rather than biological research topics (e.g. research on the role of the family by 91% of patients compared to 79% in genetics). Reasons to participate were mainly altruistic. Only a minority (28%) considered monetary incentives important. Patients wanted extensive background information and a feedback of the results; both were significantly more expressed by schizophrenia as compared to depressive patients, although these findings need to be interpreted with care because of age and gender differences between the diagnostic groups. CONCLUSION: While patients expressed discerning views of psychiatric research, only few differences were apparent between the two diagnostic groups. Patients' research priorities are not the same as those of many professionals and funding bodies. Their demonstrated critical appraisal should inform future research ensuring an increased patient role in the research process.

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) and late-onset idiopathic aqueductal stenosis (LIAS) are two forms of chronic adult hydrocephalus of different aetiology. We analysed overnight intracranial pressure (ICP) monitoring to elucidate ICP waveform changes characteristic for iNPH and LIAS to better understand pathophysiological processes of both diseases. METHODS: 98 patients with iNPH and 14 patients with LIAS from two neurosurgical centres were included. All patients underwent diagnostic overnight computerised ICP monitoring with calculation of mean ICP, ICP heartbeat related pulse wave amplitude calculated in the frequency domain (AMP) and the time domain (MWA), index of cerebrospinal compensatory reserve (RAP) and power of slow vasogenic waves (SLOW). RESULTS: ICP was higher in LIAS than iNPH patients (9.3 ± 3.0 mmHg versus 5.4 ± 4.2 mmHg, p = 0.001). AMP and MWA were higher in iNPH versus LIAS (2.36 ± 0.91 mmHg versus 1.81 ± 0.59 mmHg for AMP, p = 0.012; 6.0 ± 2.0 mmHg versus 4.9 ± 1.2 mmHg for MWA, p = 0.049). RAP and SLOW indicated impaired reserve capacity and compliance in both diseases, but did not differ between groups. INPH patients were older than LIAS patients (77 ± 6 years versus 54 ± 14 years, p < 0.001). CONCLUSIONS: ICP is higher in LIAS than in iNPH patients, likely due to the chronically obstructed CSF flow through the aqueduct, but still in a range considered normal. Interestingly, AMP/MWA was higher in iNPH patients, suggesting a possible role of high ICP pulse pressure amplitudes in iNPH pathophysiology. Cerebrospinal reserve capacity and intracranial compliance is impaired in both groups and the pressure-volume relationship might be shifted towards lower ICP values in iNPH. The physiological influence of age on ICP and AMP/MWA requires further research.

BACKGROUND: Healthcare professionals can be a source of stigma and discrimination for people with mental illness, and anti-stigma programs are needed for this target group. However, there is no validated German language scale to assess attitudes of healthcare professionals towards people with mental illness. This study had the aim to validate the German language version of the Opening Minds Stigma Scale for Health Care Providers (OMS-HC), a self-report measure of stigmatizing attitudes. METHODS: Staff (n = 392) on general psychiatric inpatient wards (excluding child, forensic and geriatric psychiatry) at five psychiatric hospitals in Switzerland (n = 3) and Germany (n = 2) participated in the study. The internal consistency of the OMS-HC was examined as well as its factor structure using exploratory and confirmatory factor analyses. To assess the scale's concurrent validity, we used the Social Distance Scale. RESULTS: Internal consistency for the OMS-HC total score was good (α = 0.74), acceptable for the subscales Attitudes (α = 0.62) and Social Distance (α = 0.69), and poor for the Disclosure subscale (α = 0.55). The original three-factor structure fit our data well. The OMS-HC total score and the Social Distance subscale score were significantly correlated with the Social Distance Scale, supporting concurrent validity. CONCLUSION: The German version of the OMS-HC demonstrated satisfactory psychometric properties and can be recommended for future research and intervention evaluation.

OBJECTIVE: To evaluate the concept of a cerebrovascular pressure reactivity-guided optimal cerebral perfusion pressure after traumatic brain injury by analyzing the relationship between optimal cerebral perfusion pressure and brain tissue oxygen. DESIGN: Prospective observational cohort study. SETTING: Neurosurgical intensive care unit of a university hospital. PATIENTS: Thirty-eight patients after head injury. INTERVENTIONS: Continuous computerized monitoring of mean arterial pressure, intracranial pressure, and brain tissue oxygen for 5.3 +/- 2.6 days. The index of cerebrovascular pressure reactivity was calculated as a moving correlation coefficient between spontaneous low-frequency fluctuations of mean arterial pressure and intracranial pressure. Optimal cerebral perfusion pressure was defined as the cerebral perfusion pressure level with the lowest average index of cerebrovascular pressure reactivity. MEASUREMENTS AND MAIN RESULTS: Optimal cerebral perfusion pressure could be identified in 32 of 38 patients. Median optimal cerebral perfusion pressure was between 70 and 75 mm Hg (range, 60-100 mm Hg). Below the level of optimal cerebral perfusion pressure, brain tissue oxygen decreased in parallel to cerebral perfusion pressure, whereas brain tissue oxygen reached a plateau above optimal cerebral perfusion pressure. Optimal cerebral perfusion pressure correlated significantly with the cerebral perfusion pressure level, where brain tissue oxygen reached its plateau (r = .79; p < .01). Average brain tissue oxygen at optimal cerebral perfusion pressure was 24.5 +/- 6.0 mm Hg. CONCLUSIONS: This study supports the concept of cerebrovascular pressure reactivity-based individual optimal cerebral perfusion pressure. Driving cerebral perfusion pressure in excess of optimal cerebral perfusion pressure does not yield improvements in brain tissue oxygen after head injury and should be avoided, whereas cerebral perfusion pressure below optimal cerebral perfusion pressure may result in secondary cerebral ischemia.

In many countries fewer than 20% of individuals with schizophrenia receive depot antipsychotic medication. Frequently stated reasons are psychiatrist's, patient's and relative's objections to depot treatment. This is the first study that directly compares the attitudes to depot antipsychotics of psychiatrists, patients and relatives. A semi-structured questionnaire about their attitudes towards depot antipsychotics was completed by 255 participants (83 patients diagnosed with schizophrenic disorder, 81 psychiatrists in private practice and 91 relatives, not directly related to the patients). Patients were more negative towards depot injections than psychiatrists and relatives. They particularly fear to be constricted in their autonomy when treated with depot antipsychotics and that injections might be painful. About 67% of all patients in our sample did not receive information about depot antipsychotics from their psychiatrist. Less than 10% of psychiatrists offer depot treatment after a first psychotic episode. Psychiatrists use depot antipsychotics in a conservative way, although they attribute positive traits to the method. Patients' negative attitudes might relate to the low level of information. To enhance the use of depot antipsychotics, information practices of psychiatrists should be improved. Patients should be informed about different forms of treatment during early stages of the illness.

Interventions aimed at enhancing psychiatric patients' outpatient treatment adherence frequently include informal coercion such as inducements, and threats of negative sanctions. Little is known about patients' subjective perspective concerning these practices. This study examined the perceived coercion, and also the appraisal of the fairness and effectiveness of the treatment. A total of 187 psychiatric patients with different diagnoses were interviewed using a structured questionnaire that included socio-demographic and clinical data, insight into illness (ITAQ), psychopathology (BPRS), functioning (GAF) and a modified version of the MacArthur Admission Experience Survey (AES) as a measure of perceived coercion, fairness and effectiveness. Bivariate correlations and logistic regression analyses were used to identify the influencing factors on the outcome variables. Perceived coercion was associated with experience with informal coercive treatment pressures (OR 2.5-2.9; P<0.05), and a main diagnosis of a schizophrenic disorder (OR 3.8; P<0.001). Experience with informal coercion was inversely associated with fairness (OR 0.3-0.4; P<0.05), but not with effectiveness. Patients with more insight into their illness indicated higher fairness and effectiveness concerning the procedures for enhancing their treatment adherence (OR 3.1; P<0.01). Insight into illness was not associated with perceived coercion. This might indicate that enhancing insight using psycho-educational approaches and high transparency when applying informal coercive practices could improve patients' appreciation for these procedures. They could probably cope better with perceived coercion when understanding its purpose, and when they perceive they are being treated fairly.
