Hospital admissions for obsessive-compulsive disorder in NSW, 1997 to 2010

OBJECTIVES

To assess the characteristics of admissions to NSW hospitals with a diagnosis of obsessive-compulsive disorder (OCD).

METHOD

Assessment of administrative data from all NSW hospital admissions from 1997 to 2010.

RESULTS

The average admission rate for a primary diagnosis of OCD was 1.5 per 100,000 population. This rate increased over the period assessed. OCD was much more common as a secondary diagnosis (6.1 per 100,000 population), often occurring with affective disorders in adults and other anxiety disorders in children. Adults admitted with OCD had an average length of stay of 24 days.

CONCLUSIONS

Although hospital admissions of patients with OCD are uncommon, the high rates of comorbidity and increasing rates of admission alert us to the significance of screening patients for OCD and being able to offer outpatient treatment.

The rates of co-occurring behavioural addictions in treatment-seeking individuals with obsessive-compulsive disorder: a preliminary report

Objectives: To assess the rates of co-occurring putative 'behavioural addictions' in patients with obsessive-compulsive disorder (OCD).Methods: Twenty-three international centres specialising in the treatment of OCD were invited to participate in a survey of the rates of behavioural addictions and other relevant comorbidity within their samples.Results: Sixteen of 23 (69.6%) invited centres from 13 countries had sufficient data to participate in the survey. The use of validated diagnostic tools was discrepant, with most centres relying on a 'clinical diagnosis' to diagnose behavioural addictions. The final sample comprised of 6916 patients with a primary diagnosis of OCD. The reported rates of behavioural addictions were as follows: 8.7% for problematic internet use, 6.8% for compulsive sexual behaviour disorder, 6.4% for compulsive buying, 4.1% for gambling disorder and 3.4% for internet gaming disorder.Conclusions: Behavioural addictions should be better assessed for patients with OCD. The absence of diagnostic scales developed specifically for behavioural addictions and overlapping obsessive-compulsive phenomena such as compulsive checking of information on the internet may explain the relatively high rate of problematic internet use in this sample. The study encourages better efforts to assess and to conceptualise the relatedness of behavioural addictions to obsessive-compulsive 'spectrum' disorders.

A prospective clinical cohort-based study of the prevalence of OCD, obsessive compulsive and related disorders, and tics in families of patients with OCD

BACKGROUND

The lifetime prevalence of obsessive - compulsive disorder (OCD) is currently estimated at 2 - 3% and the prevalence in first-degree family members is estimated to range between 10 and 11%. Separating OCD from other anxiety disorders and including it into the new "obsessive - compulsive and related disorders" (OCRDs) category has had a dramatic impact on the diagnosis, while also contributing to the better understanding of the genetics of these disorders. Indeed, grouping OCD with body dysmorphic disorder (BDD), and body-focused repetitive behaviors such as trichotillomania (hair pulling), onychophagia (nail biting), and excoriation (skin picking) into the same diagnostic family has resulted in a much greater lifetime prevalence (> 9%). These diagnostic changes necessitate an updated epidemiological study, thus motivating this investigation.

METHODS

The study sample comprised of 457 patient's cases from an Israeli and an Australian OCD center. Interviews were completed as a part of the intake or during treatment in each of the centers. Prevalence of OCD, OCRDs, tics, and other psychiatric comorbidities in first- and second-degree relatives was assessed by interviewing the OCD patients. Interviews were conducted by at least two researchers (LC, OBA, JZ) and only family information on which the interviewers have reached consensus was considered.

RESULTS

Initial analyses revealed an increase of OCD and OCRD prevalence in first- and second-degree family members as compared to the current literature due to reclassification of these disorders in DSM-5.

CONCLUSION

The new category of OCRD has changed the landscape of epidemiological studies in OCD. Further and broader studies are needed in order to better understand the lifetime prevalence of OCRD in first- and second-degrees family member.

Routine treatment duration for clients attending a community based anxiety disorders clinic

OBJECTIVE

To determine the average duration of treatment at a community-based anxiety disorders clinic.

METHOD

Data were collected on primary disorder, the presence of co-occurring disorders and treatment length (both in terms of number of sessions and weeks of therapy) for 248 consecutive clients.

RESULTS

The mean number of sessions was 13, and average treatment length was 29 weeks. There was substantial variation in treatment duration (range for number of sessions = 1-128, range for treatment duration = 0-186 weeks).

CONCLUSION

Clients with anxiety disorders were often treated in relatively few sessions, in line with randomised controlled trials (RCTs). However, a number of clients required many more sessions and were treated for a longer period of time than clients in RCTs. Health services should be cautious in mandating limits to therapy duration for anxiety disorders given the wide range in the duration of treatment for clients in our sample.

A brief intervention to improve rates and quality of physical examinations for admissions to acute adult psychiatry units

OBJECTIVE

To determine the frequency and quality of physical examinations within 24 h of admission to an acute adult psychiatry unit, and whether a brief intervention involving feedback to clinicians could lead to improvement.

METHOD

Retrospective review of the electronic medical records followed by four brief feedback sessions and email correspondence, followed by a further review of the medical records 1 month later.

RESULTS

The proportion of patients receiving a physical examination increased from 36/71 (50.7%) in the initial audit to 41/64 (64.1%) in the re-audit. The mean score of the quality of physical examinations improved from 7.5 to 9.3 (out of 15). The greatest improvement on re-audit occurred in the documentation of additional cardiac sounds (33.9% increase), additional breath sounds (17.7% increase), breath sounds (17.1% increase), cardiac sounds (14.2% increase) and bowel sounds (12.5% increase).

CONCLUSION

This audit supports the use of brief peer-led feedback to improve the rates and quality of physical examinations.

Does emotional reasoning change during cognitive behavioural therapy for anxiety?

Emotional reasoning refers to the use of subjective emotions, rather than objective evidence, to form conclusions about oneself and the world. It is a key interpretative bias in cognitive models of anxiety disorders and appears to be especially evident in individuals with anxiety disorders. However, the amenability of emotional reasoning to change during treatment has not yet been investigated. We sought to determine whether emotional reasoning tendencies change during a course of routine cognitive-behavioural therapy (CBT). Emotional reasoning tendencies were assessed in 36 individuals with a primary anxiety disorder who were seeking treatment at an outpatient clinic. Changes in anxiety and depressive symptoms as well as emotional reasoning tendencies after 12 sessions of CBT were examined in 25 individuals for whom there was complete data. Emotional reasoning tendencies were evident at pretreatment assessment. Although anxiety and depressive symptoms decreased during CBT, only one of six emotional reasoning interpretative styles (pertaining to conclusions that one is incompetent) changed significantly during the course of therapy. Attrition rates were high and there was not enough information regarding the extent to which therapy specifically focused on addressing emotional reasoning tendencies. Individuals seeking treatment for anxiety disorders appear to engage in emotional reasoning, however routine individual CBT does not appear to result in changes in emotional reasoning tendencies.

Evaluating the Effectiveness of Joint Specialist Case Conferences in Improving Diabetes Control in Patients With Schizophrenia on Clozapine

ABSTRACT

Clozapine treatment for schizophrenia is typically long-term and is associated with a high rate of diabetes. Mental health and diabetes specialist teams at a local hospital in Australia have undertaken a series of joint specialist case conferences (JSCCs) where the diabetes team works with the psychiatry team to improve diabetes management. In this retrospective cohort study conducted between 2013 and 2018, we found that glycemic control in clozapine clinics linked with JSCCs was improved significantly compared with that in the non-JSCC clinics. In the non-JSCC clozapine clinics (control), the poor glycemic control rates stayed at a similar level: 23% in 2013 and 24% in 2018. In contrast, whereas the control patients' poor glycemic rate in JSCC clozapine clinics in 2013 was 24%, it decreased markedly in 2018 to 13%. This study indicates that JSCCs can improve diabetes outcomes in a group of patients with severe mental illness.

A network analysis of obsessive-compulsive symptoms and their comorbidity with other disorders

OBJECTIVES

To improve our understanding of the heterogeneity of obsessive-compulsive disorder (OCD) and its comorbidity with other disorders by using network analysis.

METHODS

An existing data base of 257 participants with a primary diagnosis of OCD and whose symptoms were evaluated using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was subjected to network analysis.

RESULTS

The analysis revealed eight clusters of characteristics. Two clusters were too small in numbers to reach any meaningful conclusion. The other six clusters included patients with: 1) contamination and cleaning symptoms with little comorbidity; 2) high prevalence checking symptoms with comorbid depression and anxiety disorders; 3) high prevalence contamination and cleaning symptoms with aggressive obsessions and checking compulsions; 4) high prevalence hoarding symptoms with comorbid depression and anxiety; 5) high prevalence impulsive aggressive, sexual and checking symptoms, hair-pulling and comorbid body dysmorphic disorder; and 6) high prevalence hoarding with impulsive aggressive and checking symptoms with comorbid alcohol use disorder and psychosis.

CONCLUSIONS

This study highlights the potential role of comorbidity. Contamination/cleaning symptoms were observed to have less psychiatric comorbidity. Symmetry/ordering symptoms did not feature prominently in the symptom clusters, whilst checking compulsions were common to multiple clusters.

An international survey of different transcranial magnetic stimulation (TMS) protocols for patients with obsessive-compulsive disorder (OCD)

This study aims to evaluate current preferences and trends in the delivery of Transcranial Magnetic Stimulation (TMS) for Obsessive-Compulsive Disorder (OCD). A 10-item online questionnaire was developed and conducted online between April to June 2020, surveying providers of TMS for patients with OCD internationally. A total of 27 valid responses were analysed from 10 countries. The most common target for TMS was the supplementary motor area and stimulation was commonly given bilaterally, but techniques differed between centres. Exposure tasks were not commonly used during TMS. The study calls for more research clarifying the best mode of TMS delivery for OCD.

Psychic euosmia among obsessive-compulsive personality disorder patients: A case control study

BACKGROUND

Psychic euosmia (PE) has been described as a supposed psychological predisposition for which pleasant smells elicit an immediate sense of pleasure, order and calmness in obsessive-compulsive personality disorder (OCPD). In this study we tried to verify the interpretation that PE is the counterpart of disgust that has been associated to contamination and moral purity. Disgust and morality are significantly associated in people with obsessive-compulsive personality traits. We expected that OCPD patients would experience higher levels of PE.

AIM

To investigate the PE frequency in OCPD patients and healthy controls (HC) and to evaluate the relationship between PE and disgust.

METHODS

A single-center, case-control study was conducted in an outpatient service for obsessive-compulsive and related disorders. The sample consisted of 129 subjects: 45 OCPD patients and 84 HC. In both groups we submitted the Disgust Scale Revised (DS-R) and the self-report Structured Clinical Interview for DSM-5 Screening Personality Questionnaire to which we added an additional yes or no question to investigate the presence of PE. In order to verify differences between groups, t-test was employed for continuous variables and ² test for categorical variable; odds ratio was employed to analyze group differences in the PE survey. Correlation was explored with Pearson r correlations.

RESULTS

No differences were observed between groups in gender composition or education. A slight significant difference was found in mean age (t = 1.988; P = 0.049). The present study revealed significantly higher proportions of PE among OCPD patients when compared to HC (OR: 5.3, 2.28-12.46). Patients with OCPD were more likely to report PE (n = 36; 80%) whereas a much lower proportion endorsed PE in the HC group (n = 36; 42.9%). Interestingly, no differences were observed between groups in mean score for the Disgust Scale. There was also no difference between the two groups in any of the Disgust Scale Revised subscales. Moreover, no significant correlations were observed in the OCPD group between PE and Disgust Scale Revised subscales.

CONCLUSION

Results suggested that PE might be part of the clinical spectrum of OCPD, and it does not reflect the counterpart of disgust. This could also indicate that this phenomenon is a manifestation of orderliness or incompleteness. Further studies will need to be undertaken to better understand PE and its significance in OCPD.

A streamlined multidisciplinary metabolic clinic in psychiatric recovery service: a pilot study

Background

The metabolic syndrome (MetS) is a collection of risk factors for cardiovascular disease and type-2 diabetes, that includes central obesity, hypertension, hyperglycaemia and dyslipidaemia. An audit indicated inadequate MetS screening in an Australian psychiatric recovery service.

Objectives

We aimed to improve MetS screening, identification and intervention by offering streamlined lifestyle education, clinical reviews and discharge planning. This pilot program prioritized holistic, culturally-sensitive, patient-centric, and trauma-informed approaches to enhance metabolic health outcomes.

Methods

A Metabolic Clinic was piloted in two psychiatric rehabilitation cottages (n=35), which involved disciplines of dietetics, exercise physiology, diversional therapy, occupational therapy, peer workforce, social work, clinical psychology, pharmacy, nursing and medical. Another cottage (n=15) was assigned as the comparison and received standard care. A 12-week, 3-times-per-week lifestyle and behavioral program, called MetFit, was devised and offered to those identified at screening for the treatment cottages. Outcome measures were feasibility measures, the five metabolic parameters (waist circumference, blood pressure, fasting serum triglycerides, high-density lipoprotein, and glucose), functional measures, and a meal questionnaire.

Results

The treatment cottages had qualitative advantages in screening and identifying MetS. Of four enrolled consumers in MetFit, an improvement of triglycerides (p=0.08), squats (p=0.02), and push-ups (p=0.07) was observed. Major challenges of enrolment included an overall lack of acknowledgment of its importance, poor motivation of consumers and resources limitation.

Conclusions

The one-stop provision of groups, peer support and inpatient pathway with multidisciplinary team-integration was generally accepted by consumers and the MDT and has iteratively demonstrated the urgent need for consumer-centered physical care and a cultural shift to foster collaboration within a psychiatric service.

A pioneer in the management of Australian psychiatric services: Dr Richard Greenup (1803-1866)

OBJECTIVES

To provide a brief biography of Dr Richard Greenup and to explore the legacy he has left to one of Australia's longest operating psychiatric services.

METHODS

This history was obtained by consulting staff working within Cumberland Hospital, New South Wales and by examining primary and secondary sources.

RESULTS

Greenup was the second surgeon superintendent of 'The Parramatta Lunatic Asylum' from 1852 until 1866 when he was fatally stabbed with a pair of scissors by a patient. Greenup was involved in establishing The University of Sydney and advocated for expanded and improved services for people diagnosed with mental disorders.

CONCLUSIONS

Greenup recognised the needs of the mentally ill and sought to address similar social and demographic determinants of health to those that we face today. The challenges he faced, and his tragic end remind us of the importance of delivering patient-centred care whilst being mindful of associated risks.
