Satisfaction with the Injection Experience of a New, Citrate-Free Formulation of Ixekizumab

INTRODUCTION

A new, citrate-free ixekizumab formulation, which is bioequivalent to the original formulation, was associated with significant reduction in injection site pain. This study evaluates patient satisfaction with the first injection experience of citrate-free ixekizumab in a real-world setting.

METHODS

A non-interventional, observational, web-based survey of adults (≥ 18 years) with psoriasis, psoriatic arthritis, or axial spondyloarthritis was conducted between August 2022 and March 2023. Patients enrolled in the Taltz US Customer Support Program were identified as receiving either the original ixekizumab or initiating citrate-free ixekizumab. Patients receiving original ixekizumab completed one survey at baseline to assess satisfaction with the formulation and one survey after switching to assess satisfaction, willingness to continue using and recommending citrate-free ixekizumab, and formulation preference. Participants previously exposed to ixekizumab completed one survey to assess their satisfaction and willingness to continue using and recommending citrate-free ixekizumab. Descriptive and comparative statistics are reported for patients that switched from original to citrate-free ixekizumab (n = 361); and descriptive statistics are reported for patients not previously exposed to ixekizumab (n = 90).

RESULTS

A total of 451 patients were included in the analysis. Significantly more patients were satisfied with their first injection with citrate-free ixekizumab compared to original ixekizumab (83.9% vs. 71.7% respectively; p = 0.0001). Almost all patients who switched from original ixekizumab were definitely or mostly willing to continue using and recommending citrate-free ixekizumab (93.9% and 93.4%, respectively). Additionally, 94.2% of patients who switched from original to citrate-free ixekizumab preferred citrate-free ixekizumab or had no preference. Three-fourths of patients not previously exposed to ixekizumab were satisfied with their first injection with citrate-free ixekizumab and 94.5% were definitely or mostly willing to continue using citrate-free ixekizumab.

CONCLUSION

The citrate-free ixekizumab formulation was preferred and well accepted by most patients who switched from the original ixekizumab formulation. Similar findings were seen for those newly initiating citrate-free ixekizumab.

Ixekizumab Real-World Effectiveness at 24 Weeks in Patients with Psoriasis: Data from the United States Taltz Customer Support Program

INTRODUCTION

Ixekizumab, a highly selective interleukin-17A monoclonal antibody, was approved for the treatment of moderate-to-severe psoriasis (PsO) in 2016. Limited real-world data are available on its effectiveness from a patient's perspective shortly (2 to 4 weeks) after initiation and upon continuation for 24 weeks.

OBJECTIVE

To describe patient-reported clinical and quality-of-life outcomes after initiating ixekizumab using data collected from the United States Taltz® Customer Support Program.

METHODS

This was a 24-week prospective, observational study of commercially insured diagnosis-confirmed adults with PsO. Surveys were completed at weeks 0 (baseline), 2, 4, 8, 12, and 24 and included the Patient Report of Extent of Psoriasis Involvement questionnaire to assess the extent of body surface area (BSA) affected by PsO, itch and pain numeric rating scales, Patient Global Assessment of Disease Severity (PatGA), and Dermatology Life Quality Index (DLQI).

RESULTS

523 patients were included in the analysis. Proportions of patients with ≤ 2% BSA involvement were 34.5%, 40.1%, 50.9%, and 79.9% at weeks 0, 2, 4, and 24, respectively; 54.8% and 75.1% achieved National Psoriasis Foundation preferred (BSA ≤ 1%) and acceptable (BSA ≤ 3% or ≥ 75% improvement) responses at week 12, respectively. Improvements of ≥ 4 points in itch and pain were seen by week 2 in 21.1% and 28.0% of patients, respectively, which increased to 63.1% and 64.8% at week 24. Proportions of patients with PatGA scores of 0 (clear) or 1 were 13.4%, 24.1%, 34.0%, and 69.6% at weeks 0, 2, 4, and 24, respectively; and proportions with DLQI total scores of 0 or 1 [no or minimal impact] were 8.4%, 17.6%, 27.3%, and 53.8% at weeks 0, 2, 4, and 24, respectively.

CONCLUSION

Patient-reported improvements in BSA, itch, skin pain, dermatology-specific quality of life, and overall PsO severity were seen as early as 2 weeks after initiation and continued through week 24.

210 AUDIT OF AN AUDIT: UNDERSTANDING THE INTERPRETATION AND REPORTING OF KEY PERFORMANCE VARIABLES OF THE IRISH NATIONAL AUDIT OF STROKE

Background

The Irish National Audit of Stroke (INAS) coordinates the collection and analysis of key performance variables which can be interpreted as proxies of care quality in stroke. Time metrics such as “Time-to-CT” and “Time-to-Thrombolysis” reflect the organisation of in-hospital stroke care pathways, with shorter times reflecting better care coordination and quality. While the INAS data dictionary defines each variable, differing interpretations of a definition can impact on the exact data point collected. We wished to understand the interpretation and reporting of key performance variables at all clinical sites reporting to INAS.

Methods

An online survey in three parts was designed and distributed to 34 INAS audit co-ordinators along with the INAS dictionary definition of each data variable. Audit co-ordinators were asked to select the exact data point they collect for that variable from a dropdown list, with space also allotted for free-text entry of any challenges they may encounter for that variable.

Results

Responses were received from 11/34 audit co-ordinators, representing 10/24 hospitals. Variability was seen in the specific times selected for data points including hospital arrival time, team time, and brain imaging time. This variability was seen across sites and regions. Data points with less scope for interpretation such as thrombolysis or thrombolysis time showed less variability.

Conclusion

By understanding the scope of responses given to any data point definition and the challenges that may exist for audit co-ordinators, it is hoped to achieve a consensus approach to defining variables for a robust core data set. Future data definitions may be refined to assist in the collection of exact data points that are accurate, consistent and reproducible across hospital sites. In so doing, all key elements of a patient’s pathway can be captured accurately and compared with best practice guidelines with a view to optimising future care provision and service organisation.

119 ENHANCING THE QUALITY OF STROKE CARE IN IRELAND - DEVELOPMENT OF AN IRISH NATIONAL STROKE AUDIT

Background

Population ageing, stroke treatment advances, changing models of care, and between-hospital heterogeneity in stroke outcomes demonstrate the necessity of continual audit of stroke care to support quality improvement at local and national levels, and to enhance patient recovery and wellbeing. This project aims to identify the core minimum datasets for acute and non-acute stroke care, and Patient-Reported Outcome Measures (PROMs), for integration in to the newly-developed Irish National Audit of Stroke (INAS), in addition to identifying resourcing needs and implementation procedures.

Methods

In Phase 1, a minimum dataset for acute stroke care was identified based on a scoping review of international practice and available guidelines. Phase 2 (ongoing) involves identifying datasets for non-acute rehabilitative and follow-up care based on a scoping review of international practice, iterative cycles of qualitative stakeholder engagement, and systematic review of PROMs. In Phase 3, a review of resourcing and data collection procedures used in stroke audits internationally will be used to produce an implementation strategy for data collection, contextualised to the Irish healthcare system.

Results

Twenty-one eligible international stroke registries were identified from the scoping review. Within Phase 1, core clinical and thrombectomy items in the Irish registry were benchmarked against internationally-collected items to identify common items and to generate an inventory of items that other registries collect that Ireland does not. Based on consensus agreement on the most frequently-occurring international items, as reviewed by key stakeholders, a core minimum dataset for audit of acute stroke care was delivered.

Conclusion

These minimum datasets shall act as the “gold standard” for evaluating stroke care in Ireland, by not only incorporating structure, process, and care quality outcome indicators, but also PROMs. The resultant datasets may inform policy and quality improvement initiatives, and shape health service delivery across the trajectory of stroke care, from hyper-acute care, to rehabilitation, and return to the community.

Association Between Proportion of Workday Treating COVID-19 and Depression, Anxiety, and PTSD Outcomes in US Physicians

OBJECTIVE

The primary objective of this cross-sectional study was to examine the association between time spent treating patients with Coronavirus disease 2019 (COVID-19) and levels of depression, anxiety, and posttraumatic stress disorder (PTSD) in US physicians.

METHODS

The authors conducted an anonymous online survey of US physicians. Linear regression was used to test the association between proportion of day treating COVID-19 and symptoms of depression, anxiety, and PTSD.

RESULTS

In a sample of 1724 US physicians, proportion of day treating COVID-19 was positively and significantly associated with depression, anxiety, and PTSD scores (P < 0.001 for each).

CONCLUSIONS

Mental health resources should be provided to physicians who treat COVID-19 because the proportion of day treating COVID-19 is associated with depression, anxiety, and PTSD outcomes.

6 Immunological aspects of ovarian follicle ovulation and corpus luteum formation in cattle

Ovarian follicle ovulation and subsequent luteinization have been described as a controlled inflammatory event, comprising tissue damage and repair. To elaborate this further in cattle, the contribution of immune cells to dominant follicle luteinization, ovulation, and corpus luteum formation was investigated. Ovulation in beef heifers was synchronized using an 8-day progesterone-based synchronization program. Heifers were slaughtered at a local abattoir at 5 timepoints (T): (T1) 24h before ovulation (n=10); (T2) 2h before ovulation (n=9); (T3) 6h after ovulation (n=10); (T4) 24h after ovulation (n=10); (T5) 72h after ovulation (n=10), and ovarian tissue was collected and returned to the laboratory on ice. Follicular fluid, theca, granulosa, and corpus luteum (CL) tissues were recovered by dissection and processed for analysis. The concentrations of a panel of cytokines were measured using an antibody-conjugated magnetic bead immunoassay. The abundance of T-lymphocytes, mast cells, neutrophils, eosinophils, monocytes, macrophages, and dendritic cells was determined by immunohistochemistry. The mRNA relative abundance of candidate genes, including angiogenic growth factors, adhesion factors, chemokines and cytokines, was determined by quantitative real-time PCR analysis. The resulting datasets were analysed using the linear mixed model procedure of SAS and data are presented as least squares means; reported differences were deemed significant at P≤0.05. The cytokines IFNy, IP-10, IL-10, IL-36RA, MCP-1, MIP-1a, MIP-1b, and VEGF-A were detected in follicular fluid. The concentrations (pg mL−1) of IL-10 and VEGF-A were significantly higher in T1 follicular fluid samples compared with T2 (7.70 vs. 0.86 and 2193.33 vs. 293.93, respectively). Although dendritic cells were the most abundant cells in bovine ovulatory follicular and early corpus luteum tissue at all time points (P&lt;0.05), their numbers peaked in ovulatory (T2) thecal tissue (261.5 cells/mm2). The greatest number of neutrophils was identified in thecal tissue at T1 (45/mm2); thereafter, their numbers declined to 1.1/mm2 in CL tissue by T5. Similarly, the numbers of T-lymphocytes, mast cells, monocytes, and macrophages declined in CL tissue at T4 and T5. Candidate gene mRNA expression profiles appeared to be time- and tissue-specific; for example, IFNA was highest in the preovulatory granulosa tissue (T1), IL8 was highest in peri-ovulatory thecal tissue (T2), VEGFA and MMP9 were highest in the early CL tissue (T4 and T5), MMP1, TIMP1, and VCAM1 expression was highest in theca, granulosa, and CL tissue collected on or after ovulation (T2, T4, T5), expression of the prostaglandin-related genes PTGES and PTGS2 was lowest in CL tissue, and that of PTGIS was highest. The current findings support the hypothesis that ovulation in heifers is characterised by an initial proinflammatory cascade followed by a dramatic switch to tissue repair, growth, and remodelling, all occurring within a 72-h period and commencing with the LH surge. Our results highlight the roles of neutrophils, dendritic cells, and macrophages as the key actors in this process.

Measuring What Matters to Individuals with Angelman Syndrome and Their Families: Development of a Patient-Centered Disease Concept Model

Angelman syndrome (AS) is a complex, heterogeneous, and life-long neurodevelopmental disorder. Despite the considerable impact on individuals and caregivers, no disease-modifying treatments are available. To support holistic clinical management and the development of AS-specific outcome measures for clinical studies, we conducted primary and secondary research identifying the impact of symptoms on individuals with AS and their unmet need. This qualitative research adopted a rigorous step-wise approach, aggregating information from published literature, then evaluating it via disease concept elicitation interviews with clinical experts and caregivers. We found that the AS-defining concepts most relevant for treatment included: impaired expressive communication, seizures, maladaptive behavior, cognitive impairment, motor function difficulties, sleep disturbance, and limited self-care abilities. We highlight the relevance of age in experiencing these key AS concepts, and the difference between the perceptions of clinicians and caregivers towards the syndrome. Finally, we outline the impact of AS on individuals, caregivers, and families.

Development of the neurotrophic keratopathy questionnaire: qualitative research

BACKGROUND

Neurotrophic keratopathy/keratitis (NK) is a rare disease of the cornea that can lead to anatomical loss of the eye. Little is known about the NK experience from the patients' perspective. The objectives of this study were to examine the symptomatic experience and impacts of NK on patients and assess the overall comprehension, relevance, and content validity of a new questionnaire.

METHODS

This was a cross-sectional, qualitative study conducted with NK patients with varying levels of disease severity, recruited from one clinical site. One-on-one interviews using concept elicitation and cognitive interviewing techniques were conducted.

RESULTS

Fourteen NK patients participated; 64.3% were female (n = 9), mean age was 65.7 ± 13.3, and 14.3% (n = 2), 21.4% (n = 3), and 64.3% (n = 9) were classified as Mackie stage I, stage II, or stage III, respectively. Participants reported 24 concepts, including: redness (n = 12, 86%), sensitivity to light (n = 11, 79%), general discomfort (n = 9, 64%), dry eye (n = 9, 64%), reduced visual acuity (n = 9, 64%), blurred vision (n = 8, 57%), and eye fatigue (n = 8, 57%). No new concepts were reported after the 13th interview. The most frequently reported impacts included frustration (n = 10, 71%), driving impairment (n = 8, 57%), reading impairment (n = 7, 50%), difficulty watching television (n = 7, 50%), and concern with potentially losing their eyesight due to NK (n = 6, 43%). Participants provided positive feedback on the draft NK Questionnaire (NKQ) and felt that it was comprehensive and relevant to their experience with NK. Additionally, the recall period, instructions, item concepts, and response options were well-understood by participants. Minor revisions were made to the tool for consistency (i.e., the timeframe "in the past 7 days" was added to items 12-14); item 14 was modified to include "how often"; examples were added to item 9.

CONCLUSIONS

The results of the concept elicitation portion of the qualitative study support the content validity of the draft NKQ. The clinically significant concepts identified in the literature and raised during concept elicitation are included as items in the questionnaire. Further assessment of the psychometric properties should be conducted in support of this new tool to measure the effect of new treatments on symptoms and impacts associated with NK.

Consensus-based perspectives of pediatric inpatient eating disorder services

OBJECTIVE

There are few evidence-based guidelines for inpatient pediatric eating disorders. The aim was to gain perspectives from those providing and receiving inpatient pediatric eating disorder care on the essential components treatment.

METHOD

A modified Delphi technique was used to develop consensus-based opinions. Participants (N = 74) were recruited for three panels: clinicians (n = 24), carers (n = 31), and patients (n = 19), who endorsed three rounds of statements online.

RESULTS

A total of 167 statements were rated, 79 were accepted and reached a consensus level of at least 75% across all panels, and 87 were rejected. All agreed that families should be involved in treatment, and thatpsychological therapy be offered in specialist inpatient units. Areas of disagreement included that patients expressed a desire for autonomy in sessions being available without carers, and that weight gain should be gradual and admissions longer, in contrast to carers and clinicians. Carers endorsed that legal frameworks should be used to retain patients if required, and that inpatients are supervised at all times, in contrast to patients and clinicians. Clinicians endorsed that food access should be restricted outside meal times, in contrast to patients and carers.

DISCUSSION

The findings indicate areas of consensus in admission criteria, and that families should be involved in treatment, family involvement in treatment, while there was disagreement across groups on topics including weight goals and nutrition management. Perspectives from patients, carers, and clinicians may be useful to consider during future revisions of best practice guidelines.

Antenatal Pertussis Vaccination: Why are General Practitioners Reluctant? A Mixed Methods StudySetting

Pertussis has a disproportionately higher morbidity and mortality in infants less than 3 months of age. International and national guidelines recommend pertussis vaccination during pregnancy, as a safe and effective way to protect these infants. Antenatal pertussis vaccination uptake rates remain suboptimal, with many health care professionals (HCPs) still not recommending it. The reasons underlying this reluctance on behalf of HCPs have not been fully established. This study aims to evaluate the current practice and attitudes of General Practitioners (GPs) with regard to antenatal pertussis vaccination. An embedded mixed method design was used. The response rate was 41% (n=109). 54% of GPs who responded (n=59) routinely recommend antenatal pertussis vaccination. Safety concerns and a sense of isolation emerged as the major qualitative themes. More safety data, adequate funding from the Health Service Executive (HSE) and support from secondary care may help to increase the GP recommendation rate and enhance vaccination uptake in pregnancy.

The Anorexia Nervosa Genetics Initiative: Study description and sample characteristics of the Australian and New Zealand arm

OBJECTIVES

Anorexia nervosa is a severe psychiatric disorder with high mortality rates. While its aetiology is poorly understood, there is evidence of a significant genetic component. The Anorexia Nervosa Genetics Initiative is an international collaboration which aims to understand the genetic basis of the disorder. This paper describes the recruitment and characteristics of the Australasian Anorexia Nervosa Genetics Initiative sample, the largest sample of individuals with anorexia nervosa ever assembled across Australia and New Zealand.

METHODS

Participants completed an online questionnaire based on the Structured Clinical Interview Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) eating disorders section. Participants who met specified case criteria for lifetime anorexia nervosa were requested to provide a DNA sample for genetic analysis.

RESULTS

Overall, the study recruited 3414 Australians and 543 New Zealanders meeting the lifetime anorexia nervosa case criteria by using a variety of conventional and social media recruitment methods. At the time of questionnaire completion, 28% had a body mass index ⩽ 18.5 kg/m². Fasting and exercise were the most commonly employed methods of weight control, and were associated with the youngest reported ages of onset. At the time of the study, 32% of participants meeting lifetime anorexia nervosa case criteria were under the care of a medical practitioner; those with current body mass index < 18.5 kg/m² were more likely to be currently receiving medical care (56%) than those with current body mass index ⩾ 18.5 kg/m² (23%). Professional treatment for eating disorders was most likely to have been received from general practitioners (45% of study participants), dietitians (42%) and outpatient programmes (42%).

CONCLUSIONS

This study was effective in assembling the largest community sample of people with lifetime anorexia nervosa in Australia and New Zealand to date. The proportion of people with anorexia nervosa currently receiving medical care, and the most common sources of treatment accessed, indicates the importance of training for general practitioners and dietitians in treating anorexia nervosa.

Prevention of eating disorders: A systematic review of randomized, controlled trials

OBJECTIVE

This systematic review evaluated the efficacy of universal, selective, and indicated eating disorder prevention.

METHOD

A systematic literature search was conducted in Medline, PsycINFO, Embase, Scopus, and the Cochrane Collaboration Library databases to January 2016. Studies were included if they were randomized, controlled trials (RCT) and tested an eating disorder prevention program. We retrieved 13 RCTs of universal prevention (N = 3,989 participants, 55% female, M age = 13.0 years), 85 RCTs of selective prevention (N = 11,949 participants, 99% female, M age = 17.6 years), and 8 RCTs of indicated prevention (N = 510 participants, 100% female, M age = 20.1 years). Meta-analysis was performed with selective prevention trials. As there were a limited number of universal and indicated trials, narrative synthesis was conducted.

RESULTS

Media literacy had the most support for universal prevention. Most universal approaches showed significant modest effects on risk factors. Dissonance-based was the best supported approach for selective prevention. Cognitive-behavior therapy (CBT), a healthy weight program, media literacy, and psychoeducation, were also effective for selective prevention and effects were maintained at follow-up. CBT was supported for indicated prevention and effects were maintained at follow-up.

DISCUSSION

The modest effects for universal prevention were likely due to floor effects. The evidence for selective prevention suggests that empirically supported approaches should be disseminated on a wider basis. Our findings suggest CBT should be offered for indicated populations. Overall, results suggest efficacy of several prevention programs for reducing risk for eating disorders, and that wider dissemination is required. © 2016 Wiley Periodicals, Inc.

Eating disorder examination: Factor structure and norms in a clinical female pediatric eating disorder sample

OBJECTIVE

The factor structure of the eating disorder examination (EDE) has never been tested in a clinical pediatric sample, and no normative data exist.

METHOD

The factor structure of an adapted EDE was examined in a clinical sample of 665 females aged 9-17 years with anorexia nervosa spectrum (70%), bulimia nervosa spectrum (12%), purging disorder (3%), and unspecified feeding and eating disorders (15%).

RESULTS

The original four-factor model was a good fit in a confirmatory factor analysis as well a higher order model with three dimensions of restraint, eating concern, and combined weight concern/shape concern. Normative data are reported for clinicians to identify the percentiles in which their patients' score.

DISCUSSION

The findings support dimensions of restraint, eating concern, weight concern, and shape concern in a clinical pediatric sample. This supports the factorial validity of the EDE, and the norms may assist clinicians to evaluate symptoms in females under 18 years.

The Impact of Blunt Thoracic Aortic Injury on Patients Aged 80 Years or Older

BACKGROUND

Blunt thoracic aortic injury (BTAI) is rare and associated with significant morbidity and mortality in trauma patients. As the population ages and life expectancy increases, the frequency of this injury will increase in the elderly and thus it behoves us to understand treatment and outcome in this patient population.

METHODS

We analysed prospectively collected data of 10 patients > 80 years old with BTAI (Group A) treated among 26,000 trauma patients over a 20-year period in a Level 1 trauma center to investigate BTAI morbidity and mortality. Age, gender, and injurity severity score (ISS) matching was performed to create a case-control study of elderly trauma patients with (Group A) and without BTAI (Group B).

RESULTS

Ten elderly trauma patients were found to have BTAI. Five (50%) were males and 5 (50%) were female. The cohort mean age was 86 years (range: 80 to 95). All but one patient (fall injury) were involved in motor vehicle accidents. The mean ISS in group A was 29 ± 12. In group A, 2 (20%) patients (ISS = 36 and 33) succumbed in the emergency department. Six (60%) patients were treated non-operatively and the remaining 2 (20%) patients (88 and 84 years) underwent open aortic repair with patch angioplasty and Dacron interposition grafting. No postoperative paraplegia or stroke related to surgery occurred. Two patients in Group A survived hospitalization and were eventually discharged. Patients in Group B had lower overall LOS, ICU LOS and 30-day mortality rates despite similar ISS.

CONCLUSION

Patients aged 80 or older who have experienced BTAI tend to have worse outcomes than those without BTAI regardless of similar ISS. Therefore, because of the low incident of this injury in general and particularly in the elderly, only pooled data from multiple institutions will be able to shed light on the complex issues surrounding treatment decisions in a group of patients with an a priori limited life expectancy.

Brief report: Correlates of inpatient psychiatric admission in children and adolescents with eating disorders

OBJECTIVE

To examine the prevalence and importance of psychological, behavioural, and situational correlates of impending psychiatric inpatient admissions in children and adolescents with eating disorders.

METHOD

The sample consisted of 285 patients (8-17 years, M = 14.4, SD = 1.49) with DSM-5 eating disorders assessed between 2006 and 2013 from the Helping to Outline Pediatric Eating Disorders (HOPE) Project. The sample was split into two groups, those with (n = 38) and without (n = 247) impending psychiatric admission; Discriminant function analysis was used to examine correlates.

RESULTS

The prevalence of impending psychiatric admission was 13.3%. Suicidal ideation provided the greatest discriminating power, followed by eating pathology, depressive symptoms, anxiety, multiple methods of weight control, binge eating, and family functioning.

CONCLUSIONS

Earlier recognition of comorbid symptoms in eating disorders in the community may reduce the number of young people with eating disorders who present needing critical psychiatric care.

Clinical presentation of eating disorders in young males at a tertiary setting

BACKGROUND

Young males with eating disorders are a neglected study population in eating disorders. The aim of this study was to provide knowledge about the clinical presentation of eating disorders in young males.

METHODS

The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project (N ~ 1000), a prospective, ongoing registry comprising consecutive paediatric (<18 years) tertiary eating disorder referrals. Young males with DSM-5 eating disorders (n = 53) were compared with young females with eating disorders (n = 704).

RESULTS

There was no significant difference in the prevalence of diagnosis of bulimia nervosa (2 % vs 11 %, p = 0.26) among sexes. Males had comparable duration of illness (9 months; p = 0.28) and a significantly earlier age of onset (M = 12 years; p <0.001). Shape concern (2.39 vs 3.57, p <0.001) and weight concern (1.97 vs 3.09, p <0.001) were lower in males, and body mass index z score (-1.61 vs -1.42, p = 0.29) and medical compromise (odds ratio [OR] = 0.64, 95 % CI: 0.36, 1.12) were comparable. Males had a two-folder higher odds of being diagnosed with unspecified feeding or eating disorders (40 % vs 22 % for females, p = 0.004). Driven exercise to control weight and shape was common and comparable in prevalence among males and females (51 % vs 47 %, p = 0.79) and males were less likely to present with self-induced vomiting (OR = 0.23, 95 % CI: 0.09, 0.59).

CONCLUSION

Boys with eating disorders are an understudied group with similarities and differences in clinical presentation from girls with eating disorders. Parents and physicians are encouraged to consider changes in weight, disturbed vital signs, and driven, frequent exercise for the purposes of controlling weight or shape, as possible signs of eating disorders among male children. Diagnostic classification, assessment instruments, conceptualisation, and treatment methods need to be refined to improve application to young males.

Delays in the stroke thrombolysis pathway--identifying areas for improvement

Despite international consensus on the benefits of thrombolysis for ischaemic stroke (IS), it remains underused. Guidelines now recommend a door-to-needle time of 60 minutes. We reviewed the rate and timeliness of thrombolysis for IS at our hospital. 323 stroke patients presented between January 2011 and April 2012.Thirty patients (10.6% of IS) were thrombolysed, mean age was 68.5 years (42 to 88) and 19 patients (63%) were male. Thirty-six patients (12.7% of IS) were not thrombolysed despite arriving within the time-window and symptom resolution was the commonest reason (15 patients; 42%). Despite most thrombolysed patients (42%) presenting to the Emergency Department during daytime working hours, there were delays at each step of the acute care pathway. The mean time for stroke team review was 23 minutes (5-50). The mean door-to-CT and the door-to-needle times were 60 minutes (25-95) and 92 minutes (46-130) respectively. In parallel with national stroke incentives, local audit can highlight barriers to uptake and efficiency within thrombolysis services.

Parent skills training treatment for parents of children and adolescents with eating disorders: a qualitative study

OBJECTIVE

This study examined the experience of parents of children with eating disorders after having participated in a skills-based training intervention.

METHOD

Eleven parents were interviewed and transcripts were analysed using inductive thematic analysis.

RESULTS

Parent responses were organised around key themes of (1) effectiveness and acceptability of the intervention; (2) interpersonal experience of the group process; and (3) feedback on intervention content. Overall, the transfer of specialist skills was highly valued by parents and applied within the home and hospital setting.

DISCUSSION

This study contributes preliminary evidence that skills-based training may improve parent self-efficacy,psychological distress, anxiety, and burden.This intervention can also be a cost-effective method for supporting carers,and future research is required to contribute data on treatment efficacy for patients in addition to parents.

A decade of data from a specialist statewide child and adolescent eating disorder service: does local service access correspond with the severity of medical and eating disorder symptoms at presentation?

BACKGROUND

Eating disorders affect up to 3% of children and adolescents, with recovery often requiring specialist treatment. A substantial literature has accrued suggesting that lower access to health care services, experienced by rural populations, has a staggering effect on health-related morbidity and mortality. The aim of this study was to evaluate whether lower service access foreshadowed a more severe medical and symptom presentation among children and adolescents presenting to a specialist eating disorders program.

METHOD

The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project registry (N ~1000), a prospective ongoing registry study comprising consecutive paediatric tertiary eating disorder referrals. The sample consisted of 399 children and adolescents aged 8 to 16 years (M =14.49, 92% female) meeting criteria for a DSM-5 eating disorder.

RESULTS

Consistent with the hypotheses, lower service access was associated with a lower body mass index z-score and a higher likelihood of medical complications at intake assessment. Contrary to our hypothesis, eating pathology assessed at intake was associated with higher service access. No relationship was observed between service access and duration of illness or percentage of body weight lost.

CONCLUSIONS

Lower service access is associated with more severe malnutrition and medical complications at referral to a specialist eating disorder program. These findings have implications for service planning and provision for rural communities to equalize health outcomes.

Comparative study of children and adolescents referred for eating disorder treatment at a specialist tertiary setting

OBJECTIVE

To examine child and adolescent differences in the clinical presentation of eating disorders (EDs) at referral to a specialist pediatric program.

METHOD

This study compared cognitive, behavioral, and physical and medical features of children (≤ 12 years) and adolescents (13-18 years) with EDs presenting to a state-wide specialist pediatric ED service over two decades (N = 656; 8-18 years; 94% female).

RESULTS

Significant differences were found between the groups. Children were more commonly male (p < .001), had lower eating pathology scores (p < .001), were less likely to binge eat (p = .02), purge (p < .001) or exercise for shape and weight control (p < .001), and lost weight at a faster rate than adolescents (p = .009), whereas adolescents were more likely to present with bulimia nervosa spectrum disorders (p = .004). Children and adolescents did not differ significantly on mean body mass index z-score, percentage of body weight lost, or indicators of medical compromise (p > .05).

DISCUSSION

The clinical presentation of EDs differs among children and adolescents, with eating pathology and behavioral symptoms less prominent among children. Frontline health professionals require knowledge of these differences to assist with early detection, diagnosis, and prognosis.

Parent-child concordance in reporting of child eating disorder pathology as assessed by the eating disorder examination

OBJECTIVE

The aim of this study was to examine parent-youth concordance in reporting of eating disorder pathology, as assessed by the Eating Disorder Examination (EDE) in a clinical pediatric sample.

METHOD

The sample comprised 619 parent-youth dyads of youth (8-18 years) presenting for treatment at a specialist eating disorder clinic. A cross-sectional correlational design was used to examine the association between parent and youth symptom reports.

RESULTS

On the whole, parent-youth inter-rater agreement was poor to moderate. Agreement was acceptable for the presence of behavioral symptoms, with the exception of excessive exercise (PAK = 0.48-0.98). There was poor inter-rater agreement on frequency of behavioral symptoms, with parents providing lower estimates than youth (ICC = 0.07-0.52). Although we predicted that inter-rater agreement on cognitive symptoms would by higher with adolescents than children, both groups were discordant with parent reports. Younger children identified less severe eating disorder cognitions than parents and the opposite occurred for adolescents. An anorexia nervosa presentation and lower malnutrition were not associated with lower inter-rater agreement, as might have been expected through ego syntonicity. Youth with bulimia nervosa presentations reported significantly higher severity of cognitive symptoms and more frequent disordered eating behaviors compared with their parents.

DISCUSSION

Results support the utility of parent-youth assessment via the EDE to obtain a wider clinical picture of eating disorder psychopathology in children and adolescents, particularly for younger children. Clinical implications pertinent to administration of the EDE and parent literacy regarding eating disorder symptoms are discussed.

Psychotropic drug prescribing in an Australian specialist child and adolescent eating disorder service: a retrospective study

BACKGROUND

To describe the rates, indications, and adverse effects of psychotropic drug prescription in a specialist tertiary hospital child and adolescent eating disorder service.

METHODS

Retrospective case note study of all active eating disorder patients (N = 115) over the period of treatment from referral to time of study (M = 2 years), covering patient demographics, clinical characteristics, drug prescriptions, indications, and adverse effects.

RESULTS

Psychotropic drugs were prescribed in 45% of cases, most commonly antidepressants (41%), followed by anxiolytics (29%) and antipsychotics (22%), with 8% initiated before referral to the specialist eating disorder program. Common indications were depressed mood, agitation, anxiety, and insomnia. Patient clinical severity and complexity was associated with prescribing. Adverse effects, mostly minor, were recorded in 23% of antidepressant prescriptions, 39% of antipsychotic prescriptions, and 13% of anxiolytic prescriptions. Second generation antipsychotic prescription was associated with subsequent new onset binge eating, in this preliminary observational study. Self-harm by overdose of psychotropics occurred in 11% of patients prescribed medication.

CONCLUSIONS

Psychotropic medications were frequently prescribed to adolescent eating disorder patients to treat distressing symptoms. Prospective randomised controlled trials to clarify efficacy and safety are needed. Given the difficulties of conducting clinical trials in this population, services are encouraged to monitor and audit medication safety and efficacy in everyday practice, and to report their findings.

A hub and spokes approach to building community capacity for eating disorders in rural Western Australia

OBJECTIVE

To determine whether an outreach community-based training program on eating disorders enhances perceived capacity of rural health and education professionals to respond to and manage eating disorders.

DESIGN

Survey conducted upon completion of outreach training.

SETTING

Rural Western Australia.

PARTICIPANTS

Health and education professionals working in rural Western Australia.

MAIN OUTCOME MEASURES

Questionnaire responses analysed via descriptive statistics and inferential tests.

RESULTS

There was a significant increase in perceived ability to identify, support and/or treat people with eating disorders among health and education professionals.

CONCLUSIONS

Outreach training up-skilled rural gatekeepers and introduced systemic health system benefits of increased consultation and liaison, a fine-tuning of referral processes, a reduction in hospital admissions and better uptake of local services by patients discharged from hospital.

The HOPE (Helping to Outline Paediatric Eating Disorders) Project: development and debut of a paediatric clinical eating disorder registry

BACKGROUND

The HOPE (Helping to Outline Paediatric Eating Disorders) Project is an ongoing registry study made up of a sequential cross-sectional sample prospectively recruited over 17 years, and is designed to answer empirical questions about paediatric eating disorders. This paper introduces the HOPE Project, describes the registry sample to-date, and discusses future directions and challenges and accomplishments. The project and clinical service were established in a tertiary academic hospital in Western Australia in 1996 with a service development grant. Research processes were inbuilt into the initial protocols and data collection was maintained in the following years. Recognisable progress with the research agenda accelerated only when dedicated research resources were obtained. The registry sample consists of consecutive children and adolescents assessed at the eating disorder program from 1996 onward. Standardised multidisciplinary data collected from family intake interview, parent and child clinical interviews, medical review, parent, child and teacher psychometric assessments, and inpatient admission records populate the HOPE Project database.

RESULTS

The registry database to-date contains 941 assessments, of whom 685 met DSM-IV diagnostic criteria for an eating disorder at admission. The majority of the sample were females (91%) from metropolitan Perth (83%). The cases with eating disorders consist of eating disorders not otherwise specified (68%), anorexia nervosa (25%) and bulimia nervosa (7%). Among those with eating disorders, a history of weight loss since illness onset was almost universal (96%) with fear of weight gain (71%) common, and the median duration of illness was 8 months.

CONCLUSIONS

Over the next five years and more, we expect that the HOPE Project will make a strong scientific contribution to paediatric eating disorders research and will have important real-world applications to clinical practice and policy as the research unfolds.

Psychometric assessment of the Injection Pen Assessment Questionnaire (IPAQ): measuring ease of use and preference with injection pens for human growth hormone

Purpose

To examine the psychometric properties of the Injection Pen Assessment Questionnaire (IPAQ) including the following: 1) item and scale characteristics (e.g., frequencies, item distributions, and factor structure), 2) reliability, and 3) validity.

Methods

Focus groups and one-on-one dyad interviews guided the development of the IPAQ. The IPAQ was subsequently tested in 136 parent–child dyads in a Phase 3, 2-month, open-label, multicenter trial for a new Genotropin® disposable pen. Factor analysis was performed to inform the development of a scoring algorithm, and reliability and validity of the IPAQ were evaluated using the data from this two months study. Psychometric analyses were conducted separately for each injection pen.

Results

Confirmatory factor analysis provides evidence supporting a second order factor solution for four subscales and a total IPAQ score. These factor analysis results support the conceptual framework developed from previous qualitative research in patient dyads using the reusable pen. However, the IPAQ subscales did not consistently meet acceptable internal consistency reliability for some group level comparisons. Cronbach’s alphas for the total IPAQ score for both pens were 0.85, exceeding acceptable levels of reliability for group comparisons.

Conclusions

The total IPAQ score is a useful measure for evaluating ease of use and preference for injection pens in clinical trials among patient dyads receiving hGH. The psychometric properties of the individual subscales, mainly the lower internal consistency reliability of some of the subscales and the predictive validity findings, do not support the use of subscale scores alone as a primary endpoint.

Evaluating symptom outcomes in gastroparesis clinical trials: validity and responsiveness of the Gastroparesis Cardinal Symptom Index-Daily Diary (GCSI-DD)

BACKGROUND

Patient-reported symptom scales are needed to evaluate treatments for gastroparesis. The Gastroparesis Cardinal Symptom Index-Daily Diary (GCSI-DD) was developed to assess daily symptoms of gastroparesis. This study evaluated the validity and responsiveness of the GCSI-DD in patients with gastroparesis.

METHODS

Symptomatic patients were started with a new treatment for gastroparesis. Patients completed the GCSI-DD each evening during a baseline week and for 8 weeks of treatment. Responders were defined based on patient and clinician global rating of change. Minimal important differences (MID) were estimated based on baseline to 4 week changes in symptoms scores for small improvements.

KEY RESULTS

Of 69 patients participating, 46 had idiopathic, 19 diabetic, and four postfundoplication gastroparesis. Excellent test-retest reliability was seen for GCSI-DD scores, and there were significant correlations between GCSI-DD scores and clinician ratings of symptom severity. Responders to treatment reported improvements in nausea [effect size (ES) = 0.42, P < 0.001], postprandial fullness, ES = 0.83, P < 0.001), bloating (ES = 0.34, P < 0.001), early satiety (ES = 0.53, P < 0.001), but lower responses for upper abdominal pain (ES = 0.29), and vomiting (ES = 0.22; P = 0.119). MIDs were 0.55 for nausea, 0.97 for excessive fullness, 0.63 for bloating, 0.77 for postprandial fullness, and 0.30 for abdominal pain. A composite score of four symptoms (Composite-1; nausea, bloating, excessive fullness, postprandial fullness) had ES of 0.61 and MID of 0.73. Composite-2 score (nausea, early satiety, bloating, abdominal pain) had a lower ES of 0.47.

CONCLUSIONS & INFERENCES

Symptoms of early satiety, nausea, postprandial fullness, and bloating were responsive to treatment for gastroparesis. A composite of these symptoms also demonstrates validity and responsiveness to treatment for gastroparesis, and may represent an acceptable endpoint for evaluating the effectiveness of medical treatments in clinical trials for gastroparesis.

Does the Female Sexual Distress Scale-Revised cover the feelings of women with HSDD?

INTRODUCTION

Distress associated with low sexual desire is a key feature of hypoactive sexual desire disorder (HSDD). Accurate, reliable, and easy-to-use diagnostic tools to measure such distress are required. The Female Sexual Distress Scale-Revised (FSDS-R) has been shown to have good discriminant validity, test-retest reliability, and internal consistency in measuring sex-related personal distress in women with HSDD. However, the content validity (relevance, clarity, comprehensiveness) of the scale must also be established.

AIM

The aim of this study was to assess the content validity of the FSDS-R and to examine the potential of Item 13 as a stand-alone measure of distress associated with decreased sexual desire.

METHODS

A single-visit content validation study was conducted in three centers in the United States. Women were screened for HSDD; those with HSDD completed the FSDS-R and then underwent debriefing to capture information on their perceptions of the instrument. Participants also rated the relevancy of every FSDS-R item, from 0 ("not at all relevant") to 4 ("extremely relevant").

MAIN OUTCOME MEASURES

Female HSDD patients' ratings of the relevance and ease of understanding of the 13 items of the FSDS-R.

RESULTS

Twenty-five women with HSDD were interviewed. Mean relevancy ratings ranged from 1.96 (Item 9) to 3.33 (Item 13). Most participants (76-100%) found every item clear and easy to understand. Item 13 alone demonstrated good content validity, and 56% of participants felt that it covered all of their feelings about their low sexual desire.

CONCLUSIONS

This study established the content validity of the FSDS-R and demonstrated that the FSDS-R total score is a relevant endpoint for women with HSDD. The tool's one item specific to low sexual desire (Item 13) was given the highest score and highest relevancy of all items, and over half the sample felt that it covered all of their feelings about their low sexual desire.

Validation of the Revised Patient Perception of Migraine Questionnaire (PPMQ-R): Measuring Satisfaction with Acute Migraine Treatment in Clinical Trials

This study was aimed to evaluate in clinical trial settings the psychometric properties of the revised Patient Perception of Migraine Questionnaire (PPMQR), a satisfaction measure for acute migraine treatment. The PPMQ-R was administered 24 h post dosing in 1304 migraineurs randomized to two identical Phase 3, single-attack trials. Reliability, concurrent and construct validity and known-groups validity were evaluated using Cronbach's α, Pearson correlations and analysis of variance, respectively. PPMQ-R scale and Total scores (Efficacy, Functionality and Ease of use) showed very good internal consistency reliability (α 0.84-0.99). Efficacy, Functionality and Total PPMQ-R scores showed large, inverse relationships with migraine pain severity, number of migraine symptoms and work ability ( r = −0.62 to −0.75; all P < 0.0001). All scales discriminated among migraine pain severity levels (all P < 0.001). The PPMQ-R has sufficient evidence of validity and reliability for measuring patient satisfaction, an important benchmark of quality and effective care.

Daily versus weekly azithromycin in cystic fibrosis patients

Four randomised, placebo-controlled trials have previously documented the clinical benefits of azithromycin (AZM) in cystic fibrosis (CF) patients. The present study examined whether the beneficial effect of AZM is equivalent when administered daily or weekly. A double-blind, randomised study was carried out in 208 CF patients aged 6-58 yrs who were assigned to AZM either 250 mg daily (n = 103) or 1,200 mg weekly (n = 105) for 6 months, with assessments at baseline and at 1, 3, 6 and 7 months. Patients were taken from five adult and children CF centres in South-east Queensland, Australia. Equivalence was demonstrated between the two groups (daily versus weekly) with respect to improvements in lung function (forced expiratory volume in one second and forced vital capacity), C-reactive protein, days spent in hospital, admission rates and nutrition (body mass index, z-scores) using 95% confidence intervals with a tolerance interval of +/-10%. In patients aged <18 yrs the daily group had significantly better improvements in z-scores for height and weight after 6 months. In children, a nutritional advantage for daily administration was found. Gastro-intestinal adverse effects were more common with weekly therapy. Apart from these findings, daily and weekly administered azithromycin demonstrated similar outcomes for cystic fibrosis patients.

Non-eating disorders psychopathology in children and adolescents with eating disorders: implications for malnutrition and symptom severity

OBJECTIVES

To compare the general psychopathology in an eating disorders (ED) and a child mental health outpatient sample and investigate the implications of comorbidity on psychological and physical measures of ED severity.

METHODS

One hundred thirty-six children and adolescents with a DSM-IV ED diagnosis were compared with age- and gender-matched controls. Measures included the Eating Disorders Examination and the Child Behavior Checklist.

RESULTS

The ED group had lower general and externalizing psychopathology scores and no difference in internalizing (anxiety-depression) symptoms. Of the anorexia nervosa group, 49% experienced comorbid psychopathology. This group had significantly higher ED psychopathology, longer duration of illness, and more gastrointestinal symptoms, but no difference in malnutrition status. Eating disorders not otherwise specified (EDNos) group measures were less influenced by comorbidity status.

CONCLUSIONS

Anxiety-depressive symptoms are very common in children and adolescents with EDs. Comorbidity status influences illness severity, especially in the anorexia nervosa group. The management implications of these findings are discussed.

Letting the family know: balancing ethics and effectiveness when notifying relatives about genetic testing for a familial disorder

OBJECTIVE

To increase the awareness among at risk relatives of the availability of genetic testing for a familial disorder while respecting their autonomy and privacy.

METHODS

This was a comparison of preintervention and postintervention cohorts of families carried out in a state wide clinical service providing genetic counselling and testing for people at risk of familial adult onset cancer. Unaffected relatives who were not clients of the service in 74 kindreds with familial mutations causing familial breast and ovarian cancer, hereditary non-polyposis colorectal cancer, or Cowden syndrome were included in the study. In the baseline cohort (41 kindreds), family members who were clients of the clinical service and had been shown to be carriers of mutations were asked to advise relatives that genetic testing was available. In the intervention cohort (33 kindreds), the clinical service obtained consent to advise at risk relatives by letter that genetic testing was available. The main outcome measures were: (a) proportion of unaffected first and second degree relatives of the proband in each family whose genetic status was clarified within 2 years of the mutation being identified in the family, and (b) concerns regarding privacy and autonomy voiced by relatives receiving these letters.

RESULTS

In the baseline cohort, the average proportion of relatives in each family whose genetic status was clarified was 23%. In the intervention cohort, the average proportion of relatives in each family whose genetic status was clarified was 40% (p = 0.001). None of the relatives in the intervention cohort complained of a breach of privacy or autonomy.

CONCLUSION

Clinical services can take an effective and proactive approach to notifying relatives who are not their clients of the availability of genetic testing without compromising principles of privacy and autonomy.

Comparison of contamination rates of catheter-drawn and peripheral blood cultures

The aim of this study was to assess the sensitivity and specificity of catheter-drawn and peripheral blood cultures. Paired blood culture samples collected over a 44-month period from a 280 bed Brisbane metropolitan hospital were analysed, using standard clinical and microbiological criteria, to determine whether blood culture isolates represented true bacteraemias or contamination. Catheter-collected cultures had a specificity of 85% compared with 97% for peripheral cultures. In only two instances (0.2%) was the diagnosis of clinically significant bacteraemia made on the basis of catheter culture alone. This study concluded that catheter-collected samples are not a good test for true bacteraemia, and that peripheral cultures are more reliable when the results of the paired cultures are discordant.
