The introduction of statistical concepts into school curricula in Australia and New Zealand in the early 1990s initiated an ongoing research program into the learning and teaching of statistics and probability in both countries. This paper reviews the contribution of Australian and New Zealand researchers to building statistical literacy at school, alongside international developments. From recognising how students develop understanding of specific statistical and probabilistic concepts, through teacher knowledge and beliefs for teaching statistics, to intervention studies and targeted teaching, the field of statistics education has grown and changed. Statistics and probability are now well established as part of the mathematics curriculum. The importance of linking statistical literacy and statistical understanding across the curriculum, as well as in STEM, has also begun to receive attention as other subjects have recognised the importance of data in their fields. Following a comprehensive review of the field in Australia and New Zealand, this paper then considers emerging areas of interest, such as new approaches to data visualisation, and suggests future research.

Objectives: Current policies for older patients do not adequately address the barriers to effective implementation of optimal care models in New Zealand, partly due to differences in patient definitions and the in-patient pathway they should follow through hospital. This research aims to: (a) synthesise a definition of a complex older patient; (b) identify and explore primary and secondary health measures; and (c) identify the primary components of a care model suitable for a tertiary hospital in the midland region of the North Island of New Zealand. Method: This mixed-methods study utilised a convergence model, in which qualitative and quantitative data were investigated separately and then combined for interpretation. Semi-structured interviews (n=11) were analysed using a general inductive method of enquiry to develop key codes, categories and themes. Univariate data analysis was employed using six years of routinely collected data of patients admitted to the emergency department and inpatient units (n=261,773) of the tertiary hospital. Results: A definition of a complex older patient was determined that incorporates chronic conditions, comorbidities and iatrogenic complications, functional decline, activities of daily living, case fatality, mortality, hospital length of stay, hospital costs, discharge destination, hospital readmission and emergency department revisit and age – not necessarily over 65 years old. Well-performing geriatric care models were found to include patient-centred care, frequent medical review, early rehabilitation, early discharge planning, a prepared environment and multidisciplinary teams. Conclusions: The findings of this New Zealand study increase understanding of acute geriatric care for complex older patients by filling a gap in policies and strategies, identifying potential components of an optimal care model and defining a complex geriatric patient. Implications for Public Health: The findings of this study present actionable opportunities for clinicians, managers, academics and policymakers to better understand a complex older patient in New Zealand, with significant relevance also for international geriatric care and to establish an effective acute geriatric care model that leads to beneficial health outcomes and provides safeguard mechanisms.

Objectives: Community based dementia prevalence studies are expensive and resource intensive. Aotearoa New Zealand (NZ) has never had a community based dementia prevalence study representing all major ethnic groups. In recent years, dementia prevalence estimates have been derived from routinely collected health data but issues of underdiagnosis and undercoding limit their utility. Capture‐recapture techniques can estimate the number of dementia cases missing from health datasets by modelling the ascertained overlaps between linked data sources. Methods: Three routinely collected national health data sets—interRAI, Public hospital discharges, and Pharmaceuticals—were linked and all prevalent cases of dementia in NZ for the year 1 January 2021–31 December 2021 were identified. Capture‐recapture analysis fitted eight loglinear models to the data, with the best fitting model used to estimate the number of prevalent cases missing from all three datasets. Results: We estimated that almost half (47.8%) of dementia cases are not present in any of the three datasets. Dementia prevalence increased from 3.7% to 7.1% (95% CI 6.9%–7.4%) in the NZ 60+ population and from 4.9% to 9.2% (95% CI 8.9%–9.6%) in the NZ 65+ population when missing cases were included. Estimates of missing cases were significantly higher (p < 0.001) in Māori (49.2%), Pacific peoples (50.6%) and Asian (59.6%) compared to Europeans (46.4%). Conclusions: This study provides updated estimates of dementia prevalence in NZ and the proportion of undiagnosed dementia in NZ, highlighting the need for better access to dementia assessment and diagnosis.

Māori adolescents are more likely to have lived through an array of adverse experiences due to unequal exposure to social disadvantage that Indigenous Māori face in Aotearoa New Zealand. Most of this disadvantage arises from intergenerational inequity resulting from the British colonial process. This study aimed to investigate how disadvantage manifests in the backgrounds of Māori adolescents with harmful sexual behaviours. Background characteristics in a sample of 1024 males (aged between 12 and 17), who were referred to a treatment programme for harmful sexual behaviour, were analysed and comparisons made between Māori and non-Māori on risk factors. Māori exhibited higher rates of risk factors (substance abuse, familial criminality, physical abuse victimisation and family violence) at different contextual levels (i.e. individual, family, school). Risks of school exclusion and sexual abuse victimisation were similar across ethnicities. Recommendations are made for prevention/treatment efforts that use holistic and culturally informed approaches. Culturally appropriate treatment for Māori with harmful sexual behaviours (HSBs) is recommended. This needs to be led by Māori, for Māori and with Māori, including whānau/family-based treatment and prevention. [ABSTRACT FROM AUTHOR]

Accessible Summary: What is known on the subject?: Seclusion is a harmful and traumatising intervention for people accessing mental health services.People who are subject to seclusion in inpatient mental health services often first experience this within the first 24 h following admission.There is limited research examining how recent contact with services impacts the likelihood of seclusion when people are admitted to inpatient services. What the paper adds to existing knowledge?: Males, Māori and Pasifika experience higher rates of seclusion within the first 24 h following inpatient admission.People perceived by clinicians as overactive, aggressive, disruptive or agitated are seven times more likely to be secluded within the first 24 h.People referred from police or justice services are three times more likely to be secluded within the first 24 h.People who had frequent contact with community mental health services prior to inpatient admission were less likely to be secluded. What are the implications for practice?: The first 24 h of inpatient admission is a critical focus for eliminating the use of seclusion. Initial interactions with people recently admitted should focus on nurturing relationships and reducing distress.Mental health staff should consider the person's cultural needs, referral pathway, recent service contact and baseline ratings on the Health of the Nation Outcomes Scales (HoNOS) when working proactively to prevent the use of seclusion in the first 24 h following admission.Strengthening the focus on nurturing relationships, cultural understanding and non‐coercive de‐escalation approaches requires leadership support and strategic workforce development. Introduction: People who experience seclusion in inpatient mental health services often do so within the first 24 h following admission. There is limited research examining the potential contributing factors, particularly recent contact with services. Aim/Question: To identify factors associated with seclusion within the first 24 h following admission into acute inpatient mental health services. Method: A retrospective analysis was undertaken using routinely collected data from Aotearoa New Zealand mental health services. Results: A higher likelihood of seclusion within the first 24 h following admission was associated with: males, Māori, Pasifika, referrals from police/justice services, inpatient transfers, recent contact with crisis assessment teams and clinician perceptions of aggression, problematic substance use, cognitive problems and hallucinations or delusions. Recent contact with community mental health services was associated with a lower likelihood. Discussion: People's cultural needs, referral pathway, recent service contact and HoNOS scores should be considered when working to prevent the use of seclusion in the first 24 h following admission. Implications for Practice: The first 24 h following inpatient admission is a critical period for preventing the use of seclusion. Nurturing relationships, cultural understanding and use of non‐coercive de‐escalation approaches can support better outcomes for people recently admitted. [ABSTRACT FROM AUTHOR]

Background: The percentage of total body surface area (%TBSA) burned and burn depth provide valuable information on burn injury severity. Objective: This study investigated the concordance between The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) codes and expert burn clinicians in assessing burn injury severity. Method: We conducted a retrospective population-based review of all patients who sustained a burn injury between July 1, 2009, and June 30, 2019, requiring admission into a specialist burn service across Australia and New Zealand. The %TBSA burned (including the percentage of full thickness burns) recorded by expert burn clinicians within the Burns Registry of Australia and New Zealand (BRANZ) were compared to ICD-10-AM coding. Results: 20,642 cases (71.5%) with ICD-10-AM code data were recorded. Overall, kappa scores (95% confidence interval [CI]) for burn size ranged from 0.64 (95% CI 0.63–0.66) to 0.86 (95% CI 0.78–0.94) indicating substantial to almost perfect agreement across all %TBSA groups. When stratified by depth, the lowest agreement was observed for < 10% TBSA and < 10% full thickness (kappa 0.03; 95% CI 0.02–0.04) and the highest agreement was observed for burns of ≥ 90% TBSA and ≥ 90% full thickness (kappa 0.72; 95% CI 0.58–0.85). Conclusion: Overall, there was substantial agreement between the BRANZ and ICD-10-AM coded data for %TBSA classification. When %TBSA classification was stratified by burn depth, greater agreement was observed for larger and deeper burns compared with smaller and superficial burns. Implications: Greater consistency in the classification of burns is needed. [ABSTRACT FROM AUTHOR]

Background Emergency department (ED) clinicians are more frequently providing care, including end-of-life care, to older people. Objectives To estimate the need for ED end-of-life care for people aged ≥65 years, describe characteristics of those dying within 48 hours of ED presentation and compare those dying in ED with those dying elsewhere. Methods We conducted a retrospective cohort study analysing data from 177 hospitals in Australia and New Zealand. Data on older people presenting to ED from January to December 2018, and those who died within 48 hours of ED presentation, were analysed using simple descriptive statistics and univariate logistic regression. Results From participating hospitals in Australia or New Zealand, 10,921 deaths in older people occurred. The 48-hour mortality rate was 6.43 per 1,000 ED presentations (95% confidence interval: 6.31–6.56). Just over a quarter (n = 3,067, 28.1%) died in ED. About one-quarter of the cohort (n = 2,887, 26.4%) was triaged into less urgent triage categories. Factors with an increased risk of dying in ED included age 65–74 years, ambulance arrival, most urgent triage categories, principal diagnosis of circulatory system disorder, and not identifying as an Aboriginal or Torres Strait Islander person. Of the 7,677 older people admitted, half (n = 3,836, 50.0%) had an encounter for palliative care prior to, or during, this presentation. Conclusions Our findings provide insight into the challenges of recognising the dying older patient and differentiating those appropriate for end-of-life care. We support recommendations for national advanced care planning registers and suggest a review of triage systems with an older person-focused lens. [ABSTRACT FROM AUTHOR]

Introduction/Purpose: Ultrasound picture archiving and communication system (PACS) databases are useful for quality improvement and clinical research but frequently contain free text that is not easily readable. Here, we present a method to extract and clean a semi‐structured echocardiography (cardiac ultrasound) PACS database. Methods: Echocardiography studies between 1 January 2010 and 31 December 2018 were extracted using a data mining tool. Numeric variables were recoded with extreme values excluded. Analysis of free text, including descriptions of the heart valves and right and left ventricular size and function, was performed using a rule‐based system. Different levels of free text variables were initially identified using commonly used phrases and then iteratively developed. Randomly selected sets of 100 studies were compared to the electronic health record to validate the data cleaning process. Results: The data validation step was performed three times in total, with Cohen's kappa ranging between 0.88 and 1.00 for the final set of data validation across all measures. Conclusion: Free text cleaning of semi‐structured PACS databases is possible using freely available open‐source software. The accuracy of this method is high, and the resulting dataset can be linked to administrative data to answer research questions. We present a method that could be used to answer clinical questions or to develop quality improvement initiatives. [ABSTRACT FROM AUTHOR]

Psychologists work extensively with people experiencing personal and mental health difficulties, providing psychological support and therapeutic interventions. While past research has established that psychologists are at risk of secondary traumatic stress and burnout (together comprising compassion fatigue), little is known about the professional and personal circumstances that mitigate their risk. The present study surveyed mental health symptoms and professional quality of life among 149 registered psychologists in Aotearoa, New Zealand (4.1% of the workforce). A broad range of experiences was considered, including psychologists' symptoms of stress, anxiety, depression, burnout, secondary traumatic stress, compassion satisfaction, and resilience, along with contextual factors including caseload, professional support, and personal circumstances, in the second year of the pandemic. Least absolute shrinkage and selection operator regression were used to identify variables that predicted compassion fatigue and compassion satisfaction. Although psychologists find their work rewarding and satisfying, our results indicate a high rate of psychological distress and risk of compassion fatigue in our cohort of psychologists, partly associated with increased stress from COVID-19. This study identifies risk factors including COVID-19-related stress, working with clients at risk, and symptoms of stress and anxiety, accounting for 59% of the variance in compassion fatigue. Additional informal supervision support, resilience, and increased employer support were predictive of increased compassion satisfaction. It is imperative to focus on professional support, personal well-being, and manageable caseloads, to ensure a future sustainable psychology workforce. Public Significance Statement: Psychologists in New Zealand report high average levels of compassion fatigue (burnout and secondary traumatic stress), stress and depressive symptoms, and low resilience, but good compassion satisfaction. Compassion fatigue is associated with stress, anxiety, COVID-19-related stress, and working with clients at risk; while compassion satisfaction is linked with additional supervision, employer support, and resilience. Psychologists' own well-being and professional quality of life should be of utmost concern for our profession, to ensure quality and sustainability of the mental health workforce.

The Baby Care Questionnaire (BCQ) is an established ordinal measure of parenting beliefs about infant care, which includes structure and attunement scales. Rasch analysis is a powerful method to examine and improve psychometric properties of ordinal scales. This study aimed to evaluate the psychometric properties and improve precision of the structure and attunement scales of the BCQ using Rasch methodology. A Partial Credit Rasch model was applied to a sample of 450 mothers from the United Kingdom (n = 225) and New Zealand (n = 225) who completed the BCQ. Initial analyses indicated acceptable reliability of the structure and attunement scales of the BCQ, but some items showed misfit to the Rasch model associated with local dependency issues in both scales. After combining locally dependent items into testlets, both scales of the BCQ met expectations of the unidimensional Rasch model and demonstrated adequate and strong reliability and invariance across countries and person factors such as participants' age and their baby's sex. This permitted the generation of conversion algorithms to transform ordinal scores into interval data to enhance the precision of both scales of the BCQ. In conclusion, using Rasch methodology, this study demonstrated robust psychometric properties of the structure and attunement scales of the BCQ after minor modifications. The ordinal-to-interval conversion tables published here can be used to further enhance the precision of the structure and attunement scales of the BCQ without changing their original response format. These findings contribute to the enhancement of precision in measuring parenting beliefs about infant care. Highlights: The Baby Care Questionnaire (BCQ) assesses parenting beliefs on infant care through structure and attunement scales. Rasch methodology assessed BCQ's psychometric properties, refining structure and attunement scales for interval-level precision. By creating testlets, both BCQ scales demonstrated strong reliability and invariance across countries and person factors. Conversion algorithms converted ordinal scores to interval scores to enhance the precision of both scales of the BCQ. [ABSTRACT FROM AUTHOR]

Participation in evidence-based parenting programs benefits parents and children, but these programs have limited reach. This study utilized a mixed-method design to investigate the parenting concerns and parenting program needs of Chinese immigrant parents in New Zealand. Parents (n = 159) were surveyed about their perceived levels of child adjustment problems, parenting confidence, and parenting risk and protective factors. Parents' knowledge and experience with parenting programs, and their program preferences were also examined. Eight Chinese parenting practitioners were interviewed about parenting challenges, parental concerns, and barriers to program participation of Chinese immigrant parents. Survey results showed that parents who gave their child higher ratings on behavior problems reported less parental self-efficacy, and more parental adjustment, family relationship, teamwork, and parenting difficulties. Parents' knowledge and experience of available parenting programs was low. Barriers to program participation included time constraints, lack of program awareness, cultural and language barriers, and no childcare provision. Parents indicated a preference for a range of delivery options including group-based, seminar, and individually tailored programs. Program features most likely to influence attendance were content that addresses personally relevant issues and children's self-development (such as coping with failure, managing negative emotions, and increasing confidence), and convenient location of program. Practitioners indicated that managing difficult child behavior and maintaining positive parent-child relationships were key parenting challenges. These concerns were linked to cultural expectations about child obedience, academic performance, and parent/grandparent relationships. Findings highlight program preferences that could be offered to meet Chinese immigrant parenting support needs and increase program participation. Highlights: Parents and practitioners highlighted challenges, concerns, and needs of Chinese immigrant parents. Parents who gave higher child behavior problems ratings reported more parenting and family relationship difficulties. Identified parenting program, delivery, and content options that could meet Chinese immigrant parenting support needs. [ABSTRACT FROM AUTHOR]

Instrumented measurements of postural control provide a more accurate insight into the motor development of children with autism. This study aimed to identify postural control deficits in autistic children during quiet standing before and after transient locomotor task. It was hypothesized that the parameters that characterize the trajectory of center of foot pressure (COP) displacement would be higher in autistic children compared to typically developing children. Sixteen autistic children aged 6–10 but without a comorbidity diagnosis, were enrolled in the study group. The control group comprised 16 typically developing peers. The assessment of the transitional task comprised four different conditions: unperturbed and perturbed transition, stepping up, and stepping down tasks. Analysis of the COP signal was carried out for three distinct phases, i.e., phase 1 – quiet standing before step initiation, phase 2 – transit, and phase 3 - quiet standing until measurement completion. The two-way ANOVA with a 2 × 4 factorial design (group × testing condition) revealed a group effect on all posturographic variables in the antero-posterior and medio-lateral directions of phase 1 and in the antero-posterior direction of phase 3. The Bonferroni post-hoc test showed the means of all those variables were significantly higher for the autistic than for typically developing children. Group allocation also had an effect on the time of transit and step length, which turned out to be significantly longer in autistic children compared to healthy peers. Autistic children show increased postural sway before and after transitional locomotor tasks compared to typically developing children. The trial was prospectively registered in the Australian and New Zealand Clinical Trials Registry (no. ACTRN12621001113842; date registered: 23.08.2021). • Autistic children show postural control deficits before and after step initiation. • Autistic children take longer to complete a step than typically developing peers. • Posturography can be used to assess postural control in autistic children.

Background: The Census of Populations and Dwellings' is the five yearly population count of Aotearoa New Zealand. Best available populations (BAP) are subnational projections based on census data and demographic assumptions developed for healthcare planning and funding allocation but are also used as the denominator for health indicator monitoring. Pacific people are systematically undercounted, but the impact on health statistics is not well studied. For COVID-19 vaccination coverage, health service user (HSU) data were considered a more reliable denominator than BAP but introduced new biases. We aimed to understand how the choice of denominator population impacts estimates of population size and health system performance for Pacific people at a local level., Methods: We described how declining census response rates affected population data quality. We compared BAP and HSU data at district level. For the indicators 'access to primary care' and 'cervical cancer screening uptake' we replaced currently used BAP denominators with HSU and examined the impact for different ethnic groups in different geographic districts., Results: Overall Census 2018 response declined by 10%, but for Māori and Pacific people by 21% and 23%, respectively. This inequitably affected BAP accuracy. Census undercount was highest in the district with the largest Pacific populations, where HSU exceeded BAP most. Notably, 'access to primary care' for Pacific people in this district consistently exceeds 100%. Using BAP, both health indicators are currently estimated as highest for Pacific people compared to other ethnic groups, but when based on HSU, they dropped to lowest. Similar, but less pronounced trends occurred in other districts. Changes in trends over time for both indicators coincided mostly with adjustments in BAP, rather than changes in the numerators., Conclusions: The current use of BAP denominators for health statistics does not enable reliable monitoring of key health indicators for Pacific people. HSU denominators are also unsuitable for monitoring health. Exploring the feasibility of a real-time population register is strongly recommended as a new, transparent, way of obtaining more reliable, timely population data to guide policymaking and underpin a more equitable health system under the health reforms. Meanwhile, reporting of ethnic specific outcomes need to include a clear assessment of the potential for bias due to inaccurate population estimates., (© 2024. The Author(s).)
