Efficacy of antipsychotics in delusional infestation.

BACKGROUND: Data remain scarce for the first-line antipsychotic choice in treating delusional infestation (DI). OBJECTIVES: We evaluated the treatment responses associated with different antipsychotics in DI patients. METHODS: We undertook a multicentre, retrospective observational study using anonymised electronic patient records from two hospitals in the United Kingdom from 1 January 2011 to 1 January 2023. Eligible participants were adults (≥18 years) diagnosed with DI treated with an antipsychotic, and had both an assigned baseline and follow-up Clinical Global Impression Scale (CGI-S) score. The CGI-S is a validated psychiatric research tool. Participants were excluded if they had known limited or non-adherence to an antipsychotic, or if no CGI-S scores were present at follow-up. First clinic visits before the initiation of an antipsychotic were assigned as the baseline CGI-S score. The last available CGI-S score before the patient either changed antipsychotic or left the clinic for any reason was used to assign follow-up CGI-S scores. The primary outcome was the response to each individual antipsychotic treatment, measured by the difference in the baseline and last available follow-up CGI-S scores. Differences in CGI-S changes between antipsychotic episodes were tested by analysis of variance (ANOVA). RESULTS: In total, 414 patient records were analysed, and data were extracted. The mean age was 61.8 years (SD 14.1). One hundred seventy (41%) of 414 patients were men and 244 (59%) were women. In total, 156 (38%) of 414 patients were eligible, yielding a total of 315 antipsychotic prescribing episodes. The ANOVA, ranking in order of treatment response, showed that the highest mean score (expressing highest treatment response) was observed in amisulpride (31 [67%] of 46) and risperidone (95 [57%] of 167), followed by some distance by quetiapine (9 [36%] of 25), aripiprazole (13 [28%] of 46) and olanzapine (7 [25%] of 28). CONCLUSIONS: Amisulpride and risperidone were associated with a higher treatment response than quetiapine, aripiprazole and olanzapine. Amisulpride and risperidone should therefore be considered the first-line treatment options in DI patients.

Comparison of coercive practices in worldwide mental healthcare: overcoming difficulties resulting from variations in monitoring strategies.

BACKGROUND: Coercive or restrictive practices such as compulsory admission, involuntary medication, seclusion and restraint impinge on individual autonomy. International consensus mandates reduction or elimination of restrictive practices in mental healthcare. To achieve this requires knowledge of the extent of these practices. AIMS: We determined rates of coercive practices and compared them across countries. METHOD: We identified nine country- or region-wide data-sets of rates and durations of restrictive practices in Australia, England, Germany, Ireland, Japan, New Zealand, The Netherlands, the USA and Wales. We compared the data-sets with each other and with mental healthcare indicators in World Health Organization and Organisation for Economic Cooperation and Development reports. RESULTS: The types and definitions of reported coercive practices varied considerably. Reported rates were highly variable, poorly reported and tracked using a diverse array of measures. However, we were able to combine duration measures to examine numbers of restrictive practices per year per 100 000 population for each country. The rates and durations of seclusion and restraint differed by factors of more than 100 between countries, with Japan showing a particularly high number of restraints. CONCLUSIONS: We recommend a common set of international measures, so that finer comparisons within and between countries can be made, and monitoring of trends to see whether alternatives to restraint are successful. These measurements should include information about the total numbers, durations and rates of coercive measures. We urge the World Health Organization to include these measures in their Mental Health Atlas.

Risk Factors for Nonattendance in Delusional Infestation: A Multicenter Observational Study.

BACKGROUND: Nonattendance is common among patients suffering from delusional infestation (DI) with a risk factor for poorer patient outcomes. OBJECTIVE: The aim of this study was to determine the incidence rate and predictors of nonattendance among patients presenting to a psychodermatology department with DI and the subsequent effect on the success of prescribing new antipsychotics. METHODS: Data of 265 patients were reviewed of the Amsterdam UMC, the Erasmus University Medical Center, the Royal London Hospital, and the Liverpool School of Tropical Medicine between January 2008 and October 2019. RESULTS: We observed that among the patients who attended the first consultation, 57% (n = 144) did not attend their second visit. Recreational drug use was significantly higher in the nonattendance group compared to the attendance group (25% against 18%). Patients who had a history of previously prescribed antipsychotics at the time of the first consultation were less likely to get prescribed antipsychotics from the psychodermatology departments for DI; however, prescribing antipsychotic drugs by the psychodermatology department did not influence nonattendance significantly. CONCLUSIONS: People suffering from DI are at high risk of nonattendance, even in specialist settings. Patients with current illicit drug use and younger patients are particularly at risk of this.

Delusional infestation in healthcare professionals: Outcomes from a multi-centre case series.

Delusional infestation (DI) describes an unwavering fixed belief of infestation with pathogens, despite a lack of medical evidence supporting this. Effective management of DI with antipsychotics is made challenging by the fixed belief that the condition is an infestation or infection rather than a mental illness. A case series of individuals diagnosed with DI included 11% who were healthcare professionals (HCPs). We sought to characterise a cohort of HCPs who presented with DI in the UK. The case notes of HCPs diagnosed with DI at specialist clinics between 2015 and 2019 were reviewed. Demographic and clinical data were obtained. Twelve HCPs were identified out of a total of 381 individuals diagnosed with DI. Median age was 52.5 (IQR = 14.5) years. 75% (n = 9) were women. Ten individuals had primary DI, whilst two had secondary DI (one to recreational drug use, one to depression). Four individuals (33%) engaged with antipsychotic treatment. Two responded well, both had secondary DI. Of the two individuals with primary DI who engaged, one did not respond to antipsychotic medication and the other was unable to tolerate two antipsychotic drugs. In Primary DI (n = 10), the rate of adherence was lower at 20% (n = 2). In DI, high engagement and adherence rates to treatment have been reported in specialist centres. Improvement has been reported as high as 70%-75%. This indicates that a large proportion of individuals who adhere to treatment appear to derive benefit. In this series, engagement with treatment by HCPs with primary DI was low at 20%, and improvement was only achieved in individuals with secondary DI. Mental illness-related stigma, feelings of distress and difficulty forming therapeutic relationships with a professional peer are significant challenges. Developing rapport is key to treatment success in DI. In HCPs this may be suboptimal due to these negative feelings, resulting in lower engagement. A diagnosis of DI in a HCP may raise concerns regarding fitness to practise. An assessment of the impact of DI and the potential to interfere with professional duties warrants consideration. We highlight the occurrence of DI in HCPs, and the apparent lower engagement with treatment in this cohort.

Psychiatry's need for Vergangenheitsbewältigung: 'culture wars', cognitive dissonance and coming to terms with the past.

UK psychiatry's sense of self rests on being part of a socially progressive national tradition. This makes it difficult to engage with more critical narratives. The process of analysing and accepting psychiatry's past can help our profession to get closer to its real self and on a path to a better future.

Aggressive behaviour of psychiatric patients with mild and borderline intellectual disabilities in general mental health care.

PURPOSE: Little is known about the associations between mild intellectual disability (MID), borderline intellectual functioning (BIF) and aggressive behaviour in general mental health care. The study aims to establish the association between aggressive behaviour and MID/BIF, analysing patient characteristics and diagnoses. METHOD: 1174 out of 1565 consecutive in-and outpatients were screened for MID/BIF with the Screener for Intelligence and Learning Disabilities (SCIL) in general mental health care in The Netherlands. During treatment, aggressive behaviour was assessed with the Staff Observation Aggression Scale-Revised (SOAS-R). We calculated odds ratios and performed a logistic and poisson regression to calculate the associations of MID/ BIF, patient characteristics and diagnoses with the probability of aggression. RESULTS: Forty-one percent of participating patients were screened positive for MID/BIF. Patients with assumed MID/BIF showed significantly more aggression at the patient and sample level (odds ratio (OR) of 2.50 for aggression and 2.52 for engaging in outwardly directed physical aggression). The proportion of patients engaging in 2-5 repeated aggression incidents was higher in assumed MID (OR = 3.01, 95% CI 1.82-4.95) and MID/BIF (OR = 4.20, 95% CI 2.45-7.22). Logistic regression showed that patients who screened positive for BIF (OR 2,0 95% CL 1.26-3.17), MID (OR 2.89, 95% CI 1.87-4.46), had a bipolar disorder (OR 3.07, 95% CI 1.79-5.28), schizophrenia (OR 2.75, 95% CI 1.80-4.19), and younger age (OR 1.69, 95% CI 1.15-2.50), were more likely to have engaged in any aggression. Poisson regression underlined these findings, showing a SCIL of 15 and below (ß = 0.61, p<0.001) was related to more incidents. CONCLUSIONS: We found an increased risk for aggression and physical aggression in patients with assumed MID/BIF. We recommend screening for intellectual functioning at the start of treatment and using measures to prevent and manage aggressive behaviour that fits patients with MID/BIF.

Prevalence, New Incidence, Course, and Risk Factors of PTSD, Depression, Anxiety, and Panic Disorder during the Covid-19 Pandemic in 11 Countries.

We aimed to evaluate the prevalence and incidence of post-traumatic stress disorder (PTSD), depression, anxiety, and panic disorder (PD) among citizens in 11 countries during the Covid-19 pandemic. We explored risks and protective factors most associated with the development of these mental health disorders and their course at 68 days follow up. We acquired 9543 unique responses via an online survey that was disseminated in UK, Belgium, Netherlands, Bulgaria, Czech Republic, Finland, India, Latvia, Poland, Romania, and Sweden. The prevalence and new incidence during the pandemic for at least one disorder was 48.6% and 17.6%, with the new incidence of PTSD, anxiety, depression, and panic disorder being 11.4%, 8.4%, 9.3%, and 3%, respectively. Higher resilience was associated with lower mental health burden for all disorders. Ten to thirteen associated factors explained 79% of the variance in PTSD, 80% in anxiety, 78% in depression, and 89% in PD. To reduce the mental health burden, governments should refrain from implementing many highly restrictive and lasting containment measures. Public health campaigns should focus their effort on alleviating stress and fear, promoting resilience, building public trust in government and medical care, and persuading the population of the measures' effectiveness. Psychosocial services and resources should be allocated to facilitate individual and community-level recovery from the pandemic.

Perceived Effectiveness, Restrictiveness, and Compliance with Containment Measures against the Covid-19 Pandemic: An International Comparative Study in 11 Countries.

National governments took action to delay the transmission of the coronavirus (SARS-CoV-2) by implementing different containment measures. We developed an online survey that included 44 different containment measures. We aimed to assess how effective citizens perceive these measures, which measures are perceived as violation of citizens' personal freedoms, which opinions and demographic factors have an effect on compliance with the measures, and what governments can do to most effectively improve citizens' compliance. The survey was disseminated in 11 countries: UK, Belgium, Netherlands, Bulgaria, Czech Republic, Finland, India, Latvia, Poland, Romania, and Sweden. We acquired 9543 unique responses. Our findings show significant differences across countries in perceived effectiveness, restrictiveness, and compliance. Governments that suffer low levels of trust should put more effort into persuading citizens, especially men, in the effectiveness of the proposed measures. They should provide financial compensation to citizens who have lost their job or income due to the containment measures to improve measure compliance. Policymakers should implement the least restrictive and most effective public health measures first during pandemic emergencies instead of implementing a combination of many restrictive measures, which has the opposite effect on citizens' adherence and undermines human rights.

Increased prevalence of intellectual disabilities in higher-intensity mental healthcare settings.

BACKGROUND: It has been suggested that people with intellectual disabilities have a higher likelihood to develop psychiatric disorders, and that their treatment prognosis is relatively poor. AIMS: We aimed to establish the prevalence of intellectual disability in different mental healthcare settings, and estimate percentage of cognitive decline. We hypothesised that the prevalence of intellectual disabilities increases with intensity of care. METHOD: A cross-sectional study was conducted in different settings in a mental healthcare trust in the Netherlands. We used the Screener for Intelligence and Learning Disabilities (SCIL) to identify suspected mild intellectual disability (MID) or borderline intellectual functioning (BIF). We identified patients with a high level of education and low SCIL score to estimate which patients may have had cognitive decline. RESULTS: We included 1213 consecutive patients. Over all settings, 41.4% of participating patients were positive for MID/BIF and 20.2% were positive for MID only. Prevalence of suspected MID/BIF increased by setting, from 27.1% in out-patient settings to 41.9% in flexible assertive community treatment teams and admission wards, to 66.9% in long-stay wards. Only 85 (7.1%) of all patients were identified as possibly having cognitive decline. Of these, 25.9% were in long-stay wards and had a diagnosis of schizophrenia or substance use disorder. CONCLUSIONS: Low intellectual functioning is common in Dutch mental healthcare settings. Only a modest number of patients were identified as suffering from cognitive decline rather than suspected MID/BIF from birth. Therefore, we recommend improved screening of psychiatric patients for intellectual functioning at the start of treatment.

Incapacity in childbirth - Rare or common?

OBJECTIVE: Impaired decision making ability is common on general medical wards. Audit evidence suggests that the prevalence of incapacity may be higher than previously assumed in Obstetric Emergency Procedures (OEP) during childbirth. We investigated the prevalence of incapacity in OEP and factors associated with this. DESIGN: Capacity to consent to treatment was assessed retrospectively in 93 women undergoing OEP. All women were interviewed using a semi-structured questionnaire aided interview within 24 h of the emergency. Five assessors (3 obstetricians and 2 psychiatrists) were asked to determine capacity to consent from audio recordings of the interviews. RESULTS: All 5 assessors determined 59 % of women to have capacity to consent to treatment and 2 % of women to lack capacity. In 39 % of women there was some disagreement between assessors. Using a majority decision (3 assessors in agreement), 14 % of women lacked capacity. High pain scores, young age and no previous history of theatre deliveries were associated with more incapacity judgments, whilst parity and history of mental illness were not. Using a 7point Likert scale only marginally improved agreement between assessors, compared to their binary decision. CONCLUSION: It is often assumed that it is rare to lack capacity in an obstetric emergency procedure during childbirth, but these data suggest that incapacity may be relatively common. In particular, severe pain is a demonstrable risk factor for impaired capacity. Wide variation between assessors questions the validity of current commonly employed (informal) methods used in clinical practice to assess capacity to consent during OEP.

The Compulsory Care Act: Early Observations and Expectations of In- or Outpatient Involuntary Treatment.

BACKGROUND: On January 1, 2020, the Dutch Compulsory Care Act (WvGGZ) replaced the Special Admissions Act (BOPZ). While the old law only allowed compulsory treatment in hospitals, the new law allows it both inside and outside the hospital. Moreover, the new law prioritizes the patient's own opinion on coercive measures. By following patients' own choices, the Compulsory Care Act is hoped to lead to fewer admission days and less inpatient compulsory treatment in involuntarily admitted patients. METHODS: We studied the seclusion and enforced-medication events before and after January 1, 2020, using coercive measures monitoring data in a Mental Health Trust. Trends in hours of seclusion and the number of enforced-medication events per month from 2012 to 2019 were compared with 2020. We used generalized linear models to perform time series analysis. Logistic regression analyses and generalized linear models were performed to investigate whether patient compilation determined some of the observed changes in seclusion use or enforced-medication events. RESULTS: The mean number of hours of seclusion between 2012 and 2019 was 27,124 per year, decreasing from 48,542 in 2012 to 21,133 in 2019 to 3,844 h in 2020. The mean incidence of enforced-medication events between 2012 and 2019 was 167, increasing from 90 in 2012 to 361 in 2019 and then fell to 294 in 2020. In 2020, we observed 3,844 h of seclusion and 294 enforced-medication events. Near to no outpatient coercion was reported, even though it was warranted. The time series analysis showed a significant effect of the year 2020 on seclusion hours (ß = -1.867; Exp(ß) = 0.155, Wald = 27.22, p = 0.001), but not on enforced-medication events [ß = 0.48; Exp(ß) = 1.616, Wald = 2.33, p = 0.13]. DISCUSSION: There was a reduction in the number of seclusion hours after the introduction of the Compulsory Care Act. The number of enforced-medication events also increased from a very low baseline, but from 2017 onwards. To see whether these findings are consistent over time, they need to be replicated in the near future. CONCLUSION: We observed a significant increase in enforced-medication use and a decrease in seclusion hours. The year 2020 predicted seclusion hours, but not enforced-medication events.

Capacity issues at the front door.

Decision-making capacity is often overestimated by clinicians. An average of one third of patients lack capacity to make complex decisions and clinicians should be alert to such a possibility. Cognitive impairment, acute infection, intoxication and other common medical and psychiatric problems can impair patients' capacity. The Mental Capacity Act 2005 has to be applied when treating patients who lack capacity. The main decision maker for a proposed treatment or investigation is responsible for assessing capacity. However, all clinicians have to consider and assess capacity, and act in a patient's best interests if he/she lacks capacity.

Restraint guidelines for mental health services in India.

Restraint use in mentally ill patients are regulated by Mental Healthcare Act 2017 in India. At times, persons with mental disorders become dangerous to self, others or towards the property, warranting an emergency intervention in the form of restraint. Restraint as a matter of policy, should be implemented after attempting alternatives, only under extreme circumstances as last resort and not as a punishment. It should be an intervention focused at managing the concerned behavior for a given point of time. Restraint should always result in safety and should ensure that the human rights of mental health care users are upheld. This guideline was developed towards Indian mental health services in conjunction with international evidence-based strategies following a decade of collaborative research work between Indian and European mental health professionals.

Clinician attitude and perspective on the use of coercive measures in clinical practice from tertiary care mental health establishment - A cross-sectional study.

BACKGROUND: Use of coercive measures in mental health care is an important issue for research. There are scarce data available on perception and attitudes toward coercion among Indian psychiatrists. AIMS: This study aims to study psychiatrists' attitude and perspectives on the use of coercive measure in clinical practice against the background of family and patients' opinion. MATERIALS AND METHODS: The study was conducted at the Department of Psychiatry, National Institute of Mental Health and Neurosciences, Bengaluru, India. Psychiatrist in charge of the inpatients was asked about their general opinion on coercion and was administered Staff Attitude to Coercion Scale questionnaire. Findings were compared to previously published studies on patients' opinion and family opinion in the same sample. Data were analyzed using descriptive statistics. RESULTS: Coercion proved to be a common measure applied in nearly 70% of the patients studied. The 189 psychiatrists participating in the study almost all perceived coercion as care, protection and safety, and as protection from dangerous situations. About 66% of psychiatrists perceived physical and chemical restraint (sedation) as necessary and acceptable in acute emergency care. One-third of the psychiatrists felt their patients lost autonomy, dignity, and the possibility of interpersonal contact. The same amount agreed that some patients could have been treated with less restriction and fewer coercive measures. CONCLUSION: Psychiatrists felt that physical and chemical restraints are necessary and acceptable in acute emergencies. Most psychiatrists considered coercion as a caring protective and safety attitude but also acknowledged its potential negative impact on patient dignity and therapeutic relationships.

International variations in mental-health law regulating involuntary commitment of psychiatric patients as measured by the Mental Health Legislation Attitudes Scale.

Previous research illustrated that the laws regulating involuntary placement and treatment of people with mental-health problems are diverse across countries. International studies comparing satisfaction levels between countries are rare. We compared the opinions of professionals and family members about the operation of the national mental-health law regulating forcibly admission and treatment of psychiatric patients in 11 countries: Ireland, Iceland, England and Wales, Romania, Slovenia, Denmark, Germany, Sweden, Norway and India. An online survey design was adopted using a Mental Health Legislation Attitudes Scale (MHLAS). This brief nine-item questionnaire was distributed via email to psychiatrists, general practitioners, acute and community mental-health nurses, tribunal members, police officers and family members in each collaborating country. The levels of agreement/disagreement were measured on a Likert scale. Data were analysed both per question and with regard to a total MHLAS 'approval' score computed as a sum of the nine questions. We found that respondents in England and Wales and Denmark expressed the highest approval for their national legislation (76% and 74%, respectively), with those in India and Ireland expressing the lowest approval (65% and 64%, respectively). Almost all countries had a more positive attitude in comparison to Ireland on the admission criteria for involuntary placement and the way people are transferred to psychiatric hospitals. There are significant variations across Europe and beyond in terms of approval for how the national mental-health law framework operates in each country.

Delusional infestation managed in a combined tropical medicine and psychiatry clinic.

Background: Delusional infestation (DI) is a well-recognised delusional disorder presenting as the persisting belief in the presence of parasitic or other infestations. Combined clinics have been run by dermatology and psychiatry in a small number of centres. Here we report the first few years of a unique combined clinic run with experts in infectious diseases/tropical medicine and psychiatric management of DI. Methods: We reviewed all patients seen at the combined assessment clinics run at the Liverpool School of Tropical Medicine between 19 December 2011 and 31 October 2016. Data were collected prospectively as part of clinical assessment. Descriptive analysis of these data was performed to examine clinical features at assessment, investigations performed and treatment outcomes. Results: A total of 75 patients were assessed and 52 (69%) were given the formal diagnosis of DI. A history of travel was given by 64% of individuals but no significant tropical or infectious diagnosis was made. Of those who returned for follow-up, 61% reported improvement in symptoms. The Clinical Global Impressions Severity scale improvement was 1.36 for DI patients but only 0.63 for non-DI patients. DI patients were more impaired at baseline (5.0 vs 4.1). Health anxiety was the most common diagnosis seen in those not considered to have DI. Conclusions: Combined clinics to treat DI are effective in improving patient outcome. A significant minority of patients referred do not have a diagnosis of DI.

Restraint prevalence and perceived coercion among psychiatric inpatients from South India: A prospective study.

BACKGROUND: The Indian Mental Health Care Act 2017 (MHCA -2017) advocates the duty to provide treatment in the least coercive manner. Little data exists on how Indian patients perceive coercion in medical settings. AIMS: To study the prevalence of restraint in a Indian psychiatric inpatient unit, and to examine the level of perceived coercion correlating to various forms of restraint. METHODOLOGY: This is a hospital based prospective observational study. Two hundred patients were recruited through computer generated random number sampling. In eligible subjects, demographic and clinical data, restraints used and assessments related to perceived coercion were completed within 3 days of admission. Perceived coercion was reassessed at the time or within 3 days before discharge. RESULTS: In 66.5% one or more restraint measures were used, physical restraints in 20%, chemical restraints in 58%, seclusion in 18%, and involuntary medication in 32%. ECT is associated with the lowest level of perceived coercion followed by isolation/seclusion, chemical restraint, involuntary medication and physical restraint. Male gender, being married, rural background, low socioeconomic status, having a mood disorder, and alcohol or drug dependence was associated with an increased risk of physical or chemical restraint. Having a mood disorder, being from a rural area and a lower socioeconomic status was associated with being subjected to more than one form of coercion. CONCLUSION: Restraint measures are more prevalent in psychiatric hospital care in India than in Europe. Physical restraint is particularly associted with higher perceived coercion.
