An Economic Evaluation of a Web-Based Management Support System for Children With Urinary Incontinence: The eADVICE Trial.

PURPOSE: Children who require specialist outpatient care typically wait substantial periods during which their condition may progress, making treatment more difficult and costly. Timely and effective therapy during this period may reduce the need for lengthy specialist care. This study evaluated the cost-effectiveness of an individualized, evidence-informed, web-based program for children with urinary incontinence awaiting a specialist appointment (Electronic Advice and Diagnosis Via the Internet following Computerized Evaluation [eADVICE]) compared to usual care. eADVICE was supervised by a primary physician and delivered by an embodied conversational agent. MATERIALS AND METHODS: A trial-based cost-effectiveness analysis was performed from the perspective of the health care funder as a substudy of eADVICE, a multicenter, waitlist-controlled, randomized trial. Outcomes measures were incremental cost per incremental change in continence status and quality of life on an intention-to-treat basis. Uncertainty was examined using cost-effectiveness planes, scenarios, and 1-way sensitivity analyses. Costs were valued in 2021 Australian dollars. RESULTS: The use of eADVICE was found to be cost saving and beneficial (dominant) over usual care, with a higher proportion of children dry over 14 days at 6 months (risk difference 0.13; 95%CI 0.02-0.23, P = .03) and mean health care costs reduced by $188 (95%CI $61-$315) per participant. CONCLUSIONS: An individualized, evidence-informed, web-based program delivered by an embodied conversational agent is likely cost saving for children with urinary incontinence awaiting a specialist appointment. The potential economic impact of such a program is favorable and substantial, and may be transferable to outpatient clinic settings for other chronic health conditions.

Development of a new computer simulated environment to screen cognition: assessing the feasibility and acceptability of Leaf Café in younger and older adults.

BACKGROUND: Existing traditional cognitive screening tools for dementia have various limitations, including overreliance on tests assessing verbal memory and, to a lesser extent, on some aspects of executive functioning. Comprehensive neuropsychological assessment is sensitive to impairment but time-intensive and expensive. Virtual reality may provide a dynamic and unique understanding of cognitive performance and increase the ecological validity of cognitive assessment. The use of virtual reality in screening for cognitive function in older persons is promising, but evidence for its use remains sparse. OBJECTIVE: Our primary aim was to examine the feasibility and acceptability of a newly developed, virtual reality assessment module, 'Leaf Café', a computer-based program that assesses cognition in an engaging, efficient, and ecologically relevant way. The secondary aim was to assess the ability of the module to discriminate between performances of younger and older adults. METHODS: A cross-sectional study was carried out in Sydney, Australia, targeting adults aged 18 years and above. Participants completed a traditional cognitive screening tool (Telephone Interview for Cognitive Status-Modified, TICS-M) and Leaf Café, a low-immersive virtual reality module designed to evaluate learning and memory, perceptual-motor function, and executive functioning. The total performance score for each participant, ranging from 0 to 180, was correlated with their cognitive performance assessed by TICS-M, using Pearson's correlation coefficient. Following module completion, participants were presented with an open and closed-question survey to capture their perceptions, attitudes, and feedback on the module, encompassing practicality, acceptability, and enjoyment. Both descriptive and content analyses were employed to interpret the obtained data. RESULTS: A sample of 131 participants (mean age 54.9 years, SD = 20.8, range 20-85) took part. The majority were female (71.8%) and born in an English-speaking country (75.8%). The mean amount of time spent in the module was 32.8 min (SD = 13.3) with a mean module score of 107.6 (SD = 38.7). Most participants completed the highest level (5; 80.5%). There was a significant correlation between Leaf Café total scores with TICS-M cognitive scores overall, and for both younger (aged 18-64 years) and older adult (aged 65 + years) groups. No significant difference was found on performance between age groups on TICS-M performance, however, younger adults had significantly better performance on the Leaf Café module than older adults (M = 124.1 vs 95.9; p < .001). Participants had similar response proportions regarding user experience with most agreeing that the module was easy to use (84%) and to navigate (85%). Compared with younger adults, older adults had lower rates of agreement on the module's design (36.8% vs 64.3%; p = .020) and support experienced (20.5% vs 53.6%; p = .007). Participants highlighted the significance of practicality and the cognitive challenges presented by the module, in terms of memory strain and user interface concerns. Feedback encompassed different opinions on the usefulness of music, with suggestions for improvements centred around clearer instructions, varied game dynamics, and considerations for diverse user needs. CONCLUSIONS: Leaf Café is a feasible and acceptable tool to be used for screening for cognitive impairment in older adults and has real-world assessment value. Further verification on the game's utility in detecting cognitive impairment is required.

A Randomized Controlled Trial of a Web-Based Management Support System for Children With Urinary Incontinence: The eADVICE Trial.

PURPOSE: Children referred to specialist outpatient clinics by primary care providers often have long waiting times before being seen. We assessed whether an individualized, web-based, evidence-informed management support for children with urinary incontinence while waiting reduced requests for specialist appointments. MATERIALS AND METHODS: A multicenter, waitlisted randomized controlled trial was conducted for children (5-18 years) with urinary incontinence referred to tertiary pediatric continence clinics. Participants were randomized to the web-based eHealth program electronic Advice and Diagnosis Via the Internet following Computerized Evaluation (eADVICE), which used an embodied conversational agent to engage with the child at the time of referral (intervention) or 6 months later (control). The primary outcome was the proportion of participants requesting a clinic appointment at 6 months. Secondary outcomes included persistent incontinence, and the Paediatric incontinence Questionnaire (PinQ) score. RESULTS: From 2018 to 2020, 239 children enrolled, with 120 randomized to eADVICE and 119 to the control arm. At baseline, participants' mean age was 8.8 years (SD 2.2), 62% were males, mean PinQ score was 5.3 (SD 2.2), 36% had daytime incontinence, and 97% had nocturnal enuresis. At 6 months, 78% of eADVICE participants vs 84% of controls requested a clinic visit (relative risk 0.92, 95% CI 0.79, 1.06, P = .3), and 23% eADVICE participants vs 10% controls were completely dry (relative risk 2.23, 95% CI 1.10, 4.50, P = .03). The adjusted mean PinQ score was 3.5 for eADVICE and 3.9 for controls (MD -0.37, 95% CI -0.71, -0.03, P = .03). CONCLUSIONS: The eADVICE eHealth program for children awaiting specialist appointments doubled the proportion who were dry at 6 months and improved quality of life but did not reduce clinic appointment requests.

Protocol for a pre-post, mixed-methods feasibility study of the Brain Bootcamp behaviour change intervention to promote healthy brain ageing in older adults.

INTRODUCTION: Behaviour change interventions represent key means for supporting healthy ageing and reducing dementia risk yet brief, scalable behaviour change interventions targeting dementia risk reduction in older adults is currently lacking. Here we describe the aims and design of the three-month Brain Bootcamp initiative that seeks to target multiple dementia risk and protective factors (healthy eating, physical, social and cognitive inactivity), through the use of multiple behaviour change techniques, including goal-setting for behaviour, information about health consequences and physical prompts to change behaviours that reduce dementia risk among older adults. Our secondary aim is to understand participants' views of dementia prevention and explore the acceptability and integration of this campaign into daily life. METHODS: Brain Bootcamp is a pre-post feasibility trial conducted in Sydney, Australia beginning in January 2021 until late August. Participants aged ≥65 years living independently in the community (n = 252), recruited through social media and flyers, will provide information about their demographics, medical history, alcohol consumption, smoking habits, mental health, physical activity, cognitive activity, and diet to generate a dementia risk profile at baseline and assess change therein at three-month follow-up. During the intervention, participants will receive a resource pack containing their individual risk profile, educational booklet on dementia risk factors and four physical items designed to prompt physical, social and mental activity, and better nutrition. Outcome measures include change in dementia risk scores, dementia awareness and motivation. A qualitative process evaluation will interview a sample of participants on the acceptability and feasibility of the intervention. DISCUSSION: This will be the first short-term multi-domain intervention targeting dementia risk reduction in older adults. Findings will generate a new evidence base on how to best support efforts targeting lifestyle changes and to identify ways to optimise acceptability and effectiveness towards brain health for older adults.

Design and Evaluation Challenges of Conversational Agents in Health Care and Well-being: Selective Review Study.

BACKGROUND: Health care and well-being are 2 main interconnected application areas of conversational agents (CAs). There is a significant increase in research, development, and commercial implementations in this area. In parallel to the increasing interest, new challenges in designing and evaluating CAs have emerged. OBJECTIVE: This study aims to identify key design, development, and evaluation challenges of CAs in health care and well-being research. The focus is on the very recent projects with their emerging challenges. METHODS: A review study was conducted with 17 invited studies, most of which were presented at the ACM (Association for Computing Machinery) CHI 2020 conference workshop on CAs for health and well-being. Eligibility criteria required the studies to involve a CA applied to a health or well-being project (ongoing or recently finished). The participating studies were asked to report on their projects' design and evaluation challenges. We used thematic analysis to review the studies. RESULTS: The findings include a range of topics from primary care to caring for older adults to health coaching. We identified 4 major themes: (1) Domain Information and Integration, (2) User-System Interaction and Partnership, (3) Evaluation, and (4) Conversational Competence. CONCLUSIONS: CAs proved their worth during the pandemic as health screening tools, and are expected to stay to further support various health care domains, especially personal health care. Growth in investment in CAs also shows the value as a personal assistant. Our study shows that while some challenges are shared with other CA application areas, safety and privacy remain the major challenges in the health care and well-being domains. An increased level of collaboration across different institutions and entities may be a promising direction to address some of the major challenges that otherwise would be too complex to be addressed by the projects with their limited scope and budget.

Conversation dynamics in a multiplayer video game with knowledge asymmetry.

Despite the challenges associated with virtually mediated communication, remote collaboration is a defining characteristic of online multiplayer gaming communities. Inspired by the teamwork exhibited by players in first-person shooter games, this study investigated the verbal and behavioral coordination of four-player teams playing a cooperative online video game. The game, Desert Herding, involved teams consisting of three ground players and one drone operator tasked to locate, corral, and contain evasive robot agents scattered across a large desert environment. Ground players could move throughout the environment, while the drone operator's role was akin to that of a "spectator" with a bird's-eye view, with access to veridical information of the locations of teammates and the to-be-corralled agents. Categorical recurrence quantification analysis (catRQA) was used to measure the communication dynamics of teams as they completed the task. Demands on coordination were manipulated by varying the ground players' ability to observe the environment with the use of game "fog." Results show that catRQA was sensitive to changes to task visibility, with reductions in task visibility reorganizing how participants conversed during the game to maintain team situation awareness. The results are discussed in the context of future work that can address how team coordination can be augmented with the inclusion of artificial agents, as synthetic teammates.

Exploring the influence of a user-specific explainable virtual advisor on health behaviour change intentions.

Virtual advisors (VAs) are being utilised almost in every service nowadays from entertainment to healthcare. To increase the user's trust in these VAs and encourage the users to follow their advice, they should have the capability of explaining their decisions, particularly, when the decision is vital such as health advice. However, the role of an explainable VA in health behaviour change is understudied. There is evidence that people tend to change their intentions towards health behaviour when the persuasion message is linked to their mental state. Thus, this study explores this link by introducing an explainable VA that provides explanation according to the user's mental state (beliefs and goals) rather than the agent's mental state as commonly utilised in explainable agents. It further explores the influence of different explanation patterns that refer to beliefs, goals, or beliefs&goals on the user's behaviour change. An explainable VA was designed to advise undergraduate students how to manage their study-related stress by motivating them to change certain behaviours. With 91 participants, the VA was evaluated and the results revealed that user-specific explanation could significantly encourage behaviour change intentions and build good user-agent relationship. Small differences were found between the three types of explanation patterns.

A descriptive analysis of sentencing decisions by the Canadian criminal justice system of people with intellectual disabilities convicted with sexual offences.

This study reviews sentencing decisions of people diagnosed with intellectual disabilities who have been convicted of sexual offences by judges in Canada. Given the prevalence of people with intellectual disabilities managed within the criminal justice system (CJS), courts have increasingly been faced with issues concerning appropriate sentencing. In addition, many people with intellectual disabilities have complex social and medical backgrounds that require multidisciplinary perspectives to account for each person's legal and moral culpability, which in turn influences sentencing decisions, including placement in prisons versus rehabilitation programs. The legal databases Canlii and LexisNexis Quicklaw were used to search full text judgements from Canadian courts for adults (over the age of 18) diagnosed with an intellectual disability and charged with a sexual offence. In total, 61 cases were included within the full-text review. These cases were analyzed based on the accused's demographics, past social history, past medical history, current diagnoses, past criminal record, current charges, mitigating/aggravating factors, use of a Gladue report, sentence, and other pertinent information that contributed to the final judgement. Recommendations on how to increase the effectiveness of the CJS in trying and sentencing people with intellectual disabilities are made based on the findings of this study.

Sex and genes, part 2: A biopsychosocial approach to assess and treat challenging sexual behavior in persons with intellectual disabilities including fragile X syndrome and 22q11.2 deletion syndrome.

Individuals with intellectual disabilities (IDs) - and specifically those with genetic disorders - are more prone to medical and psychological challenges that affect their sexual development, experiences, and fertility. In this review paper we first provide an overview of the biopsychosocial (BPS) model and then explain how the model can guide and improve the assessment and treatment of challenging sexual behaviors by persons with IDs. We discuss two genetic conditions - fragile X syndrome and 22q11.2 deletion syndrome - in case studies, showing how the BPS model can be used to assess and treat the sexual problems of individuals with various types of ID. We conclude with BPS-formulated treatment considerations in three key domains: biomedical treatment (e.g., medication side effects; stopping or changing medications), psychological treatment (e.g., providing psychological therapies), and socio-environmental interventions (e.g., providing socio-sexual education and staff training). Together, these treatment interventions can aid clinicians to prevent and/or treat problematic sexual behaviors of people with IDs.

Improving Health Outcomes Sooner Rather Than Later via an Interactive Website and Virtual Specialist.

Nonlife threatening chronic health conditions can significantly reduce the quality of life for the patient and their family. Given pressure on specialist services and lengthy wait times, we propose a novel approach that involves a website and virtual specialist for patients while they are awaiting their specialist appointment. To capture patient history and provide tailored treatment advice, an interactive website was developed. To increase adherence, the website was enhanced with an empathic embodied conversational agent to allow discussion of the suggested treatment. A six-month trial with 74 children with urinary incontinence showed an overall improvement in 74% of patients, with 38% those who used the program reporting a resolution of their wetting without needing a specialist appointment. Capturing the expertise of medical specialists to provide online tailored treatment advice and use of humanlike face-to-face conversations to educate and build rapport with the patient appeared to increase treatment adherence compared to an earlier text-based version without the empathic agent.

Changes in Influenza Vaccination Rates After Withdrawal of Live Vaccine.

BACKGROUND: Before the start of the 2016-2017 influenza season, the Advisory Committee on Immunization Practices withdrew its recommendation promoting the use of live attenuated influenza vaccines (LAIVs). There was concern that this might lessen the likelihood that those with a previous LAIV would return for an injectable influenza vaccine (IIV) and that child influenza immunization rates would decrease overall. METHODS: Using Oregon's statewide immunization registry, the ALERT Immunization Information System, child influenza immunization rates were compared across the 2012-2013 through 2016-2017 seasons. Additionally, matched cohorts of children were selected based on receipt of either an LAIV or an IIV during the 2015-2016 season. Differences between the IIV and LAIV cohorts in returning for the IIV in the 2016-2017 season were assessed. RESULTS: Overall, influenza immunization rates for children aged 2 to 17 years were unchanged between the 2015-2016 and 2016-2017 seasons. Children aged 3 to 10 with a previous IIV were 1.03 (95% confidence interval, 1.02 to 1.04) times more likely to return for an IIV in 2016-2017 than those with a previous LAIV, whereas children aged 11 to 17 years with a previous IIV were 1.08 (95% confidence interval, 1.05 to -1.09) times more likely to return. CONCLUSIONS: Withdrawal of the LAIV recommendation was not associated with an overall change in child influenza immunization rates across seasons. Children with a previous (2015-2016) IIV were slightly more likely to return during the 2016-2017 season for influenza immunization than those with a previous LAIV.

The predictive validity of common risk assessment tools in men with intellectual disabilities and problematic sexual behaviors.

This CIHR-funded study examined whether certain current risk assessment tools were effective in appraising risk of recidivism in a sample of sex offenders with intellectual disabilities (ID). Fifty men with ID who had engaged in problematic sexual behavior (PSB) were followed for an average of 2.5 years. Recidivism was defined and measured as any illegal or problematic behavior, as well as any problematic but not necessarily illegal behavior. At the beginning of the study, each participant was rated on two risk assessment tools: the Violence Risk Appraisal Guide (VRAG) and the Sex Offender Risk Appraisal Guide (SORAG). During each month of follow-up, participants were also rated on the Short-Dynamic Risk Scale (SDRS), an assessment tool intended to measure the risk of future problematic behaviors. Data was analyzed using t-tests, Cohen's d and area under the curve (AUC) to test predictive validity of the assessment tools. Using the AUC, results showed that the VRAG was predictive of sexual (AUC=0.74), sexual and/or violent (AUC=0.71) and of any criminally chargeable event (AUC=0.69). The SORAG was only significantly predictive of sexual events (AUC=0.70) and the SDRS was predictive of violent events (AUC=0.71). The t-test and Cohen's d analyses, which are less robust to deviations from the assumptions of normal and continuous distribution than AUC, did not yield significant results in each category, and therefore, while the results of this study suggest that the VRAG and the SORAG may be effective tools in measuring the short term risk of sexual recidivism; and the VRAG and SDRS may be effective tools in appraising long term risk of sexual and/or violent recidivism in this population, it should be used with caution. Regardless of the assessment tool used, risk assessments should take into account the differences between sex offenders with and without ID to ensure effective measurement.

Impact of social media on the health of children and young people.

This paper reviews the literature on the impact of social media on the health of children and young people. Relevant papers were identified from Medline, Embase and PsycINFO databases. The studies identified that the health impact of social media on children and young people was greatest on mental health and specifically in the areas of self-esteem and well-being, with related issues around cyberbullying and 'Facebook Depression', with an association between the use of social media and self-esteem and body image. However, it is difficult to determine the cause and effect, which is likely to be related to the nature of the young person. There is little work on the impact of social media on younger children. More research is needed to identify those most at risk of harm from social media and risk mitigation strategies to assist health-care professionals to provide essential education for parents and young people.

Screening and management of cardiovascular disease in Australian adults with HIV infection.

BACKGROUND: Cardiovascular disease (CVD) is common in HIV infection. With no specific Australian guidelines for the screening and management of CVD in HIV-infected patients, best clinical practice is based on data from the general population. We evaluated adherence to these recommendations by primary care physicians who treat HIV-infected patients. METHODS: Primary care physicians with a special interest in HIV infection were asked to complete details for at least 10 consecutive patient encounters using structured online forms. This included management practices pertaining to blood pressure (BP), blood glucose, electrocardiogram, lipid profile and CVD risk calculations. We assessed overall adherence to screening and follow-up recommendations as suggested by national and international guidelines. RESULTS: Between May 2009 and March 2010, 43 physicians from 25 centres completed reporting for 530 HIV-infected patients, of whom 93% were male, 25% were aged 41-50 years and 83% were treated with antiretrovirals. Risk factors for CVD were common and included smoking (38%), hyperlipidaemia (16%) and hypertension (28%). In men aged >40 years and women aged >50 years without evidence of ischaemic heart disease, only 14% received a CVD risk assessment. Lipid and BP assessments were performed in 87% and 88% of patients, respectively. CONCLUSIONS: This Australian audit provides unique information on the characteristics and management of HIV and CVD in clinical practice. We have found a high burden of risk for CVD in HIV-infected Australians, but current screening and management practices in these patients fall short of contemporary guidelines.

Phosphodiesterase type 5 inhibitors improve endothelial function and may benefit cardiovascular conditions.

The effects of phosphodiesterase type 5 inhibitors on vasodilation mediated via nitric oxide-cyclic guanosine monophosphate are well described. Less is known about other mechanisms through which phosphodiesterase type 5 inhibitors benefit endothelial function, including normalization of serum biomarkers, increased levels of endothelial progenitor cells, ischemia-reperfusion protection mechanisms, and other actions specific to patients with diabetes. These various mechanisms are reviewed. Their impact on several cardiovascular diseases, including erectile dysfunction, pulmonary hypertension, heart failure, high-altitude pulmonary edema, Raynaud's phenomenon, coronary artery disease, diabetes, and atherosclerosis, is presented.

Sex and genes, part 1: sexuality and Down, Prader-Willi, and Williams syndromes.

Specific genetic syndromes affect individuals' sexual development, experiences, and fertility. Individuals with specific syndromes can also display inappropriate sexual behavior resulting from vulnerabilities presented by their genetic makeup. Using clinical case studies, we discuss the specific impact that Down, Prader-Willi, and Williams syndromes can have on sexual development and behavior. Applying a biopsychosocial approach, we present the primary sexual effects, such as delayed sexual development and infertility. These genetic syndromes are also associated with challenges that are not specifically sexual in nature but that affect sexual expression, such as self-injury, mental health issues, or epilepsy. Medication side effects are also discussed. We conclude with treatment recommendations for individuals with sexual challenges, considering the unique effects of these three syndromes on sexuality.

A longitudinal integrated placement and medical students' intentions to practise rurally.

CONTEXT: Integrated longitudinal rural placements are designed to promote favourable student attitudes towards and facilitate return to rural practice upon graduation. We explored the impact of an integrated placement on medical students' attitudes towards rural practice. METHODS: Data were available from interviews with 10 medical students, 15 clinical supervisors and teachers, three community health staff, and focus groups made up of medical students. Socio-cognitive career theory gave insight into the personal, contextual and experiential factors, as well as the career barriers, that influence students' rural practice intentions. Framework analysis was used to develop a thematic framework illustrating the key findings. RESULTS: The longitudinal placement enabled students to achieve personal goals, and enhanced self-efficacy beliefs and orientation towards the complex personal and professional demands of rural practice. The informal curriculum, including multifaceted interactions with patients and their families, clinical teachers and other health care staff, was a vital experiential component. Students assimilated these rich experiences into their practice and evolving notions of professional identity as rural practitioners. Some students had little intention of practising rurally, partly as a result of contextual barriers such as geographic isolation, family and relationship needs, restricted postgraduate training opportunities and limited opportunities for specialist practice. CONCLUSIONS: The richness of the informal curriculum in a longitudinal rural placement powerfully influenced students' intentions to practise rurally. It provided an important context for learning and evolving notions of professionalism and rural professional identity. This richness could be reinforced by developing formal curricula using educational activities based around service-led and interprofessional learning. To overcome the contextual barriers, the rural workforce development model needs to focus on socialising medical students into rural and remote medicine. More generic issues include student selection, further expansion of structured vocational training pathways that vertically integrate with longitudinal rural placements and the maintenance of rurally focused support throughout postgraduate training.

Teenage use of GP care for moderate to severe asthma in Auckland, New Zealand.

OBJECTIVES: To describe and understand teenagers' frequency of attendance for General Practitioner (GP) care of moderate to severe asthma in the Auckland region. METHODS: Ten Auckland schools identified 510 children aged 13-14 years with breathing problems, who were invited to complete a screening questionnaire. 271 children participated, of whom 114 had moderate to severe asthma. RESULTS: 39% of the 114 had made 0-1 GP visit for asthma, and 17% made 'greater than and equal to' 5 visits. Low attendees (0-1 visit) were disproportionately New Zealand European. High attendees ('greater than and equal to' 5 visits) tended to be Maori and/or Pacific Islanders. Half of the teenagers attended GP asthma care as often as it wanted, independently of ethnicity; 62% tell their parents when they cannot manage their asthma; and 29% must pay for GP care. Expected attendance was increased for Maori and Pacific students versus others by 77% (p=0002), and by asthma of increased severity (p<0.001). Teenager resistance to accessing GP asthma care reduced expected attendance by 24% (p=0.003). CONCLUSIONS: Maori and Pacific peoples have traditionally faced barriers to accessing GP care, but their their more frequent attendance (than New Zealand Europeans) in this case, challenges whether such barriers persist, at least for acute care of moderate to severe asthma.

Attendance for general practitioner asthma care by children with moderate to severe asthma in Auckland, New Zealand.

Attendance for general practitioner (GP) care of childhood asthma varies widely in New Zealand (NZ). There is little current research to account for the variations, although groups such as Maori and Pacific peoples have traditionally faced barriers to accessing GP care. This paper aims to describe and account for attendance levels for GP asthma care among 6-9 year-olds with moderate to severe asthma in Auckland, NZ. During 2002, randomly selected schools identified all 6-9 year-olds with possible breathing problems. Completion of a questionnaire by each parent/guardian indicated which children had moderate to severe asthma, and what characteristics influenced their access to GP asthma care. A multilevel, negative binomial regression model (NBRM) was fitted to account for the number of reported GP visits for asthma, with adjustment for clustering within schools. Twenty-six schools (89.7 percent) identified 931 children with possible breathing problems. Useable questionnaires were returned to schools by 455 children (48.9 percent). Results indicated 209 children with moderate to severe asthma, almost one in every three reportedly making 5 or more GP visits for asthma in the previous year. Maori, Pacific and Asian children were disproportionately represented among these 'high attendees'. Low attendees (0-2 visits) were mainly NZ Europeans. The NBRM (n=155) showed that expected visits were increased by perceived need, ill-health, asthma severity and, in particular, Maori and Pacific child ethnicity. It may be that Maori and Pacific children no longer face significant barriers to accessing GP asthma care. However, more likely is that barriers apply only to accessing routine, preventative care, leading to poor asthma control, exacerbations requiring acute care, and paradoxically an increase in GP visits. That barriers may increase total numbers of visits challenges the assumption, for all health systems, that access can be defined in terms of barriers that must be overcome to obtain health care.
