Antenatal and early childhood exposures associated with non-fatal infant injury: evidence from a longitudinal birth cohort in New Zealand.

OBJECTIVE: To identify antenatal and early childhood exposures of unintentional injury among infants in New Zealand (NZ). METHOD: The theoretical life-course framework of child injury prevention domains was utilised to analyse data from a prospective longitudinal NZ birth cohort (Growing Up in NZ). Risk and protective factors for injury were identified using Robust Poisson regression models. RESULT: Among children included for the analysis(n=6304), 52% were male, 55% were born to European mothers, and 37% lived in a household with high levels of deprivation. Mothers reported that 6% of infants (n=406) had sustained at least one injury by 9 months. Multivariate analysis showed injury risk among single mothers with antenatal depression were more than twice that (IRR=2.20) of children of mothers with partners and without depression. CONCLUSION: Understanding antenatal risk and protective factors for infant injury will assist in implementing injury prevention programmes or modifying the existing policies that affect these vulnerable age groups.

Anxiety, Disability, and Pain Predict Outcomes of Complex Regional Pain Syndrome: An 8-year Follow-up of a Prospective Cohort.

Factors contributing to the varied outcomes of complex regional pain syndrome (CRPS) are not well known. This study aimed to determine whether baseline psychological factors, pain, and disability influence long-term CRPS outcomes. We conducted an 8-year follow-up from a previous prospective study of CRPS outcomes. Sixty-six people diagnosed with acute CRPS were previously assessed at baseline, 6 months, and 12 months and in the current study, 45 were followed up after 8 years. At each timepoint, we measured signs and symptoms of CRPS, pain, disability, and psychological factors. Mixed-model repeated measures were used to identify baseline predictors of CRPS severity, pain, and disability at 8 years. Predictors of greater CRPS severity at 8 years were female sex, greater baseline disability, and greater baseline pain. Predictors of greater pain at 8 years were greater baseline anxiety and disability. The only predictor of greater disability at 8 years was greater baseline pain. Findings suggest CRPS is best understood from a biopsychosocial perspective, and baseline anxiety, pain, and disability may influence the trajectory of CRPS outcomes as far as 8 years later. These variables could be used to identify those at risk of poor outcomes or form targets for early interventions. PERSPECTIVE: This paper presents the findings of the first study to prospectively investigate predictors of CRPS outcomes over 8 years. Baseline anxiety, pain, and disability predicted greater CRPS severity, pain, and disability over 8 years. These factors could identify those at risk of poor outcomes or form targets for early interventions.

An intersectional approach to exploring lived realities and harnessing the creativity of ethnic minority youth for health gains: protocol for a multiphase mixed method study.

BACKGROUND: Understanding the diversity and multiplicity of identities experienced by youth in Aotearoa (Te reo Maori name of the country) New Zealand (NZ) is vital to promoting their wellbeing. Ethnic minority youth (EMY) in NZ (defined as those identifying with Asian, Middle Eastern, Latin American and African ethnic origins) have been historically under-studied and under-counted, despite reporting high levels of discrimination, a major determinant of mental health and wellbeing and potentially a proxy for other inequities. In this paper, we describe the protocol for a multi-year study that examines, using an intersectional approach, how multiple marginalised identities impact mental and emotional wellbeing of EMY. METHODS: This is a multiphase, multi-method study designed to capture the diversity of lived realities of EMY who self-identify with one or more additional marginalised intersecting identity (the population referred here as EMYi). Phase 1 (Descriptive study) will involve secondary analyses of national surveys to examine the prevalence and relationships between discrimination and wellbeing of EMYi. Phase 2 (Study on public discourse) will analyse data from media narratives, complemented by interviews with stakeholders to explore discourses around EMYi. Phase 3 (Study on lived experience) will examine lived experiences of EMYi to discuss challenges and sources of resilience, and how these are influenced by public discourse. Phase 4 (Co-design phase) will use a creative approach that is youth-centered and participatory, and will involve EMYi, creative mentors and health service, policy and community stakeholders as research partners and advisors. It will employ participatory generative creative methods to explore strengths-based solutions to discriminatory experiences. DISCUSSION: This study will explore the implications of public discourse, racism and multiple forms of marginalisation on the wellbeing of EMYi. It is expected to provide evidence on the impacts of marginalisation on their mental and emotional wellbeing and inform responsive health practice and policy. Using established research tools and innovative creative means, it will enable EMYi to propose their own strength-based solutions. Further, population-based empirical research on intersectionality and health is still nascent, and even more scarce in relation to youth. This study will present the possibility of expanding its applicability in public health research focused on under-served communities.

Use of public sector diabetes eye services in New Zealand 2006-2019: Analysis of national routinely collected datasets.

OBJECTIVE: To assess diabetes eye service use in New Zealand among people aged ≥15 years by estimating service attendance, biennial screening rate, and disparities in the use of screening and treatment services. METHODS: We obtained Ministry of Health data from the National Non-Admitted Patient Collection on diabetes eye service events between 1 July 2006 and 31 December 2019 and sociodemographic and mortality data from the Virtual Diabetes Register and linked these using a unique patient identifier (encrypted National Health Index). We 1) summarized attendance at retinal screening and ophthalmology services, 2) calculated biennial and triennial screening rate, 3) summarized treatment with laser and anti-VEGF and used log-binomial regression to examine associations of all of these with age group, ethnicity, and area-level deprivation. RESULTS: In total, 245,844 people aged ≥15 years had at least one diabetes eye service appointment attended or scheduled; half of these (n = 125,821, 51.2%) attended only retinal screening, one-sixth attended only ophthalmology (n = 35,883, 14.6%) and one-third attended both (n = 78,300, 31.8%). The biennial retinal screening rate was 62.1%, with large regional variation (73.9% in Southern District to 29.2% in West Coast). Compared with NZ Europeans, Maori were approximately twice as likely to never receive diabetes eye care or to access ophthalmology when referred from retinal screening, 9% relatively less likely to receive biennial screening and received the fewest anti-VEGF injections when treatment was commenced. Disparities in service access were also present for Pacific Peoples compared to NZ Europeans, younger and older age groups compared to those aged 50-59 years and those living in areas with higher deprivation. CONCLUSIONS: Access to diabetes eye care is suboptimal, with substantial disparity between age groups, ethnicity groups, area level deprivation quintile and across districts. Efforts to improve access to and quality of diabetes eye care services must include strengthening data collection and monitoring.

Comparing primary caregivers' reported injury data with routinely recorded injury data to assess predictors of childhood injury.

BACKGROUND: Linking self-reported data collected from longitudinal studies with administrative health records is timely and cost-effective, provides the opportunity to augment information contained in each and can offset some of the limitations of both data sources. The aim of this study was to compare maternal-reported child injury data with administrative injury records and assess the level of agreement. METHODS: A deterministic linkage was undertaken to link injury-related data from the Growing up in New Zealand (GUiNZ) study to routinely collected injury records from New Zealand's Accident Compensation Corporation (ACC) for preschool children. The analyses compared: (i) the characteristics of mothers with linked data vs. those without, (ii) injury incidences from maternal recall with those recorded in ACC injury claims, and (iii) the demographic characteristics of concordant and discordant injury reports, including the validity and reliability of injury records from both data sources. RESULTS: Of all mothers who responded to the injury questions in the GUiNZ study (n = 5836), more than 95% (n = 5637) agreed to have their child's record linked to routine administrative health records. The overall discordance in injury reports showed an increasing trend as children grew older (9% at 9 M to 29% at 54 M). The mothers of children with discordance between maternal injury reports and ACC records were more likely to be younger, of Pacific ethnicity, with lower educational attainment, and live in areas of high deprivation (p < 0.001). The level of agreement between maternal injury recall and ACC injury record decreased (κ = 0.83 to κ = 0.42) as the cohort moved through their preschool years. CONCLUSIONS: In general, the findings of this study identified that there was underreporting and discordance of the maternal injury recall, which varied by the demographic characteristics of mothers and their child's age. Therefore, linking the routinely gathered injury data with maternal self-report child injury data has the potential to augment longitudinal birth cohort study data to investigate risk or protective factors associated with childhood injury.

Tuberculosis and diabetes: increased hospitalisations and mortality associated with renal impairment.

BACKGROUND: Diabetes mellitus (DM) triples a person's risk of active tuberculosis (TB) and is associated with increased mortality. It is unclear whether diabetes status and/or the associated renal dysfunction is associated with poor TB outcomes in New Zealand, which has high diabetes screening. AIM: To characterise the population of TB-DM and TB-alone to assess the effect of diabetes status and renal function on hospitalisation and mortality. METHODS: Clinical records from all adult patients diagnosed with TB in Auckland over a 6-year period (2010-2015) were reviewed. Baseline demographics, clinical presentation and microbiological data were assessed to compare the rates of hospitalisation and mortality between those with TB-DM and TB-alone. Statistical significance was defined as P < 0.05. RESULTS: A total of 701 patients was identified with TB; 120 (17%) had an unknown diabetes status and were excluded, and 135 had co-existing diabetes. The TB-DM and TB-alone groups had similar distribution of TB site and proportions of Mycobacterium tuberculosis culture positivity. Univariate analysis showed TB-DM patients had statistically significantly higher proportions of acute hospitalisation and mortality. Multivariate logistic regression showed only a reduced estimated glomerular filtration rate (eGFR) accounted for the higher rates of hospitalisation, with the odds of hospitalisation increasing by 2% for every unit decrease in eGFR. The odds of mortality increased by 6% for every year increase in age, and the odds of mortality increased by 3% for every unit reduction in eGFR. CONCLUSIONS: Diabetes is associated with higher TB hospitalisation and mortality; however, this is likely mediated by increased age and chronic kidney disease.

Geographic access to eye health services in Aotearoa New Zealand: which communities are being left behind?

CLINICAL RELEVANCE: Efforts to provide accessible eye care must consider the extent to which travel-distance may be a barrier for some communities. BACKGROUND: This study aimed to determine the distribution of - and geographic access to - eye health services in Aotearoa New Zealand. We further sought to identify communities who might benefit from provision of eye health services that were more geographically accessible. METHODS: We obtained addresses of optometry and ophthalmology clinics from regulatory bodies and augmented this with online searches. Address locators were created using a Land Information dataset and geocoded using ArcGIS 10.6. A national population was derived using Statistics New Zealand's Integrated Data Infrastructure. We generated population-weighted centroids of each of New Zealand's 50,938 meshblocks and calculated the travel distance along the road network between each clinic and population (meshblock centroid). The proportion of the population living >50 km from each clinic type was calculated; as was the median, inter-quartile range and maximum distance across area-level deprivation quintiles in each district. RESULTS: A national population of 4.88 million was identified, as were addresses for 344 optometry, 46 public ophthalmology and 90 private ophthalmology clinics. Nationally and within each district, travel distance to optometry was shorter than to either type of ophthalmology clinic. The region of Northland - with a high proportion of the population Maori and in the highest quintile of area-level deprivation - had the furthest average distance to travel to optometry and public ophthalmology, while the West Coast region on the South Island had the farthest to travel to private ophthalmology. Several communities were identified where longer distances intersected with higher area-level deprivation. CONCLUSION: Most New Zealanders live within 10 km of eye health services. However, to achieve equitable eye health, strategies are required that make affordable eye health services accessible to communities for whom large travel distances intersect with high deprivation.

Understanding the context of hospital transfers and away-from-home hospitalisations for Maori.

In Aotearoa New Zealand, people regularly travel away from their home to receive hospital care. While the role of whanau support for patients in hospital is critical for Maori, there is little information about away-from-home hospitalisations. This paper describes the frequency and patterning of away-from-home hospitalisations and inter-hospital transfers for Maori. Data from the National Minimum Dataset (NMDS), for the 6-year period of 1 January 2009-31 December 2014, were analysed. Basic frequencies, means and descriptive statistics were produced using SAS software. We found that more than 10% of all routine hospitalisations constituted an away-from-home hospitalisation for Maori; that is, a hospitalisation that was in a district health board (DHB) other than the DHB of usual residence for the patient. One quarter (25.19%) of transfer hospitalisations were to a DHB other than the patient's DHB of domicile. Away-from-home hospital admissions increase for Maori as deprivation increases for both routine and transfer admissions, with over half of Maori hospital admissions among people who live in areas of high deprivation. This analysis aids in understanding away-from-home hospitalisations for Maori whanau, the characteristics associated with these types of hospitalisations and supports the development and implementation of policies which better meet whanau Maori needs. The cumulative impact of the need to travel to hospital for care, levels of poverty and a primarily reimbursement-based travel assistance system all perpetuate an unequal cost burden placed upon Maori whanau.

Socio-economic deprivation and healthcare service use of young people with type 1 and type 2 diabetes.

AIM: Lower socio-economic status (SES) is linked to greater morbidity in people with young-onset type 2 (T2D) and type 1 diabetes (T1D). We assessed healthcare utilisation from this population and the impact of SES. METHODS: Retrospective analysis of 1,350 people with T2D and 731 with T1D diagnosed between 15-30 years of age referred to secondary diabetes services in Auckland, New Zealand. Primary care visits, referral to/attendance at diabetes clinics, and hospital admissions were recorded; their relationship to a validated national index of deprivation (NZDep) was assessed. RESULTS: The proportion with primary care attendance was similar in both groups with no significant variation with NZDep. For T2D, NZDep was a predictor of delayed referral (≧1-year post-diagnosis) to diabetes services, following adjustment for age and HbA1c in the year of diagnosis (OR 1.15 for every decile increase in NZDep, 95% CI 1.07-1.24, p=0.0003). The median number of appointments offered over a 2-year period was greater for T1D (2.0 (IQR 0, 7) vs (0 (IQR 0, 2), p<0.001); non-attendance increased with NZDep for T2D (p=0.016). The proportion with hospital admissions was similar in both groups and increased with NZDep (T1D p<0.001, T2D p=0.015). CONCLUSION: SES impacts several measures of healthcare utilisation. Current healthcare models are inadequately servicing people with young-onset T2D.

Fetal Loss and Preterm Birth Caused by Intraamniotic Haemophilus influenzae Infection, New Zealand.

Invasive Haemophilus influenzae infection during pregnancy can cause preterm birth and fetal loss, but the mechanism is unclear. We investigated 54 cases of pregnancy-associated invasive H. influenzae disease in 52 unique pregnancies in the Auckland region of New Zealand during October 1, 2008‒September 30, 2018. Intraamniotic infection was identified in 36 (66.7%) of 54 cases. Outcome data were available for 48 pregnancies. Adverse pregnancy outcomes, defined as fetal loss, preterm birth, or the birth of an infant requiring intensive/special care unit admission, occurred in 45 (93.8%) of 48 (pregnancies. Fetal loss occurred in 17 (35.4%) of 48 pregnancies, before 24 weeks' gestation in 13 cases, and at >24 weeks' gestation in 4 cases. The overall incidence of pregnancy-associated invasive H. influenzae disease was 19.9 cases/100,000 births, which exceeded the reported incidence of pregnancy-associated listeriosis in New Zealand. We also observed higher rates in younger women and women of Maori ethnicity.

The Older Persons' Index of Multiple Deprivation: Measuring the deprivation circumstances of older populations in Aotearoa New Zealand.

Existing indices of multiple deprivation exclude indicators specifically relevant to the population aged ≥65 years. In this study we create a whole-of-population cohort of people aged ≥65 years living in private dwellings and who completed the 2013 New Zealand Census of Populations and Dwellings to create an Older Persons' Index of Multiple Deprivation (OPIMD). We combined 22 indicators representing 6 domains of deprivation (Income, Housing, Health, Assets, Connectedness and Geographic access) to establish this individual-level measure of deprivation. We used smoking data from the census to validate the OPIMD and describe the geography of the OPIMD by District Health Board, contrasting these patterns with a conventional area deprivation index. The OPIMD has the potential to inform policies concerning resource allocation for the older population. An accompanying website with an interactive atlas and an online OPIMD calculator is available for wider use of the data. Further research is required to explore associations between the OPIMD and other major health and social outcomes affecting this population.

Understanding geographical variations in health system performance: a population-based study on preventable childhood hospitalisations.

OBJECTIVE: To investigate interdistrict variations in childhood ambulatory sensitive hospitalisation (ASH) over the years. DESIGN: Observational population-based study over 2008-2018 using the Primary Health Organisation Enrolment Collection (PHO) and the National Minimum Dataset hospital events databases. SETTING: New Zealand primary and secondary care. PARTICIPANTS: All children aged 0-4 years enrolled in the PHO Enrolment Collection from 2008 to 2018. MAIN OUTCOME MEASURE: ASH. RESULTS: Only 1.4% of the variability in the risk of having childhood ASH (intracluster correlation coefficient=0.014) is explained at the level of District Health Board (DHB), with the median OR of 1.23. No consistent time trend was observed for the adjusted childhood ASH at the national level, but the DHBs demonstrated different trajectories over the years. Ethnicity (being a Pacific child) followed by deprivation demonstrated stronger relationships with childhood ASH than the geography and the health system input variables. CONCLUSION: The variation in childhood ASH is explained only minimal at the DHB level. The sociodemographic variables also only partly explained the variations. Unlike the general ASH measure, the childhood ASH used in this analysis provides insights into the acute conditions sensitive to primary care services. However, further information would be required to conclude this as the DHB-level performance variations.

Measuring aniseikonia and investigating neuroplasticity and image factors in amblyopia (MAGNIFY): study protocol for a randomised clinical trial.

BACKGROUND: Aniseikonia represents a potential barrier to neuroplasticity which may limit visual outcomes in children with anisometropic amblyopia. Full correction of refractive error is the first step in standard amblyopia treatment, which corrects for image focus but neglects image size differences. METHODS: The MAGNIFY study is a double-masked, randomised clinical trial investigating the effectiveness of aniseikonia correcting lenses in children at first diagnosis of significant anisometropia. We hypothesis that aniseikonia correction lenses will improve image clarity and reduce the retinal size differences producing better visual acuity and stereoacuity improvements after 15 weeks of optical treatment for children with anisometropia. Eligible children will be randomly allocated to the treatment group (aniseikonia-correcting spectacle lenses) or control group (standard spectacle lenses). Visual acuity and binocular functions will be assessed every 5 weeks during the 15-week optical treatment phase according to standard amblyopia treatment protocol. DISCUSSION: It is possible that correcting aniseikonia along with anisometropia at first diagnosis will promote binocularity as well as increase spectacle adherence by reducing visual discomfort, improving optical treatment outcomes. This could then reduce the need for additional amblyopia treatment such as patching or atropine, reducing the burden on hospital eye departments and potentially improving visual outcomes for children with amblyopia.

Psychological well-being of women at high risk of spontaneous preterm birth cared for in a specialised preterm birth clinic: a prospective longitudinal cohort study.

OBJECTIVES: To assess the psychological well-being of pregnant women at increased risk of spontaneous preterm birth, and the impact of care from a preterm birth clinic. DESIGN: Single-centre longitudinal cohort study over 1 year, 2018-2019. SETTING: Tertiary maternity hospital in Auckland, New Zealand. PARTICIPANTS: Pregnant women at increased risk of spontaneous preterm birth receiving care in a preterm birth clinic. INTERVENTION: Participants completed three sets of questionnaires (State-Trait Anxiety Inventory, Edinburgh Postnatal Depression Scale, and 36-Item Short Form Survey)-prior to their first, after their second, and after their last clinic appointments. Study-specific questionnaires explored pregnancy-related anxiety and perceptions of care. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the mean State-Anxiety score. Secondary outcomes included depression and quality of life measures. RESULTS: 73/97 (75.3%) eligible women participated; 41.1% had a previous preterm birth, 31.5% a second trimester loss and 28.8% cervical surgery; 20.6% had a prior mental health condition. 63/73 (86.3%) women completed all questionnaires. The adjusted mean state-anxiety score was 39.0 at baseline, which decreased to 36.5 after the second visit (difference -2.5, 95% CI -5.5 to 0.5, p=0.1) and to 32.6 after the last visit (difference -3.9 from second visit, 95% CI -6.4 to -1.5, p=0.002). Rates of anxiety (state-anxiety score >40) and depression (Edinburgh Postnatal Depression Scale score >12) were 38.4%, 34.8%, 19.0% and 13.7%, 8.7%, 9.5% respectively, at the same time periods. Perceptions of care were favourable; 88.9% stated the preterm birth clinic made them significantly or somewhat less anxious and 87.3% wanted to be seen again in a future pregnancy. CONCLUSIONS: Women at increased risk of spontaneous preterm birth have high levels of anxiety. Psychological well-being improved during the second trimester; women perceived that preterm birth clinic care reduced pregnancy-related anxiety. These findings support the ongoing use and development of preterm birth clinics.

Assessment of factors associated with PSA level in prostate cancer cases and controls from three geographical regions.

It is being debated whether prostate-specific antigen (PSA)-based screening effectively reduces prostate cancer mortality. Some of the uncertainty could be related to deficiencies in the age-based PSA cut-off thresholds used in screening. Current study considered 2779 men with prostate cancer and 1606 men without a cancer diagnosis, recruited for various studies in New Zealand, US, and Taiwan. Association of PSA with demographic, lifestyle, clinical characteristics (for cases), and the aldo-keto reductase 1C3 (AKR1C3) rs12529 genetic polymorphisms were analysed using multiple linear regression and univariate modelling. Pooled multivariable analysis of cases showed that PSA was significantly associated with demographic, lifestyle, and clinical data with an interaction between ethnicity and age further modifying the association. Pooled multivariable analysis of controls data also showed that demographic and lifestyle are significantly associated with PSA level. Independent case and control analyses indicated that factors associated with PSA were specific for each cohort. Univariate analyses showed a significant age and PSA correlation among all cases and controls except for the US-European cases while genetic stratification in cases showed variability of correlation. Data suggests that unique PSA cut-off thresholds factorized with demographics, lifestyle and genetics may be more appropriate for prostate cancer screening.

Corticosteroids to safely reduce neonatal respiratory morbidity after late preterm and term planned caesarean section birth? A randomised placebo-controlled feasibility study.

OBJECTIVES: To assess the feasibility of conducting a randomised placebo-controlled trial of corticosteroids prior to planned caesarean section from 35+0 to 39+6 weeks. DESIGN: A triple-blind, placebo-controlled, parallel, trial randomised at the participant level (1:1 ratio). Additional feasibility data obtained by questionnaires from trial participants and women who declined trial participation, and focus groups with local site researchers and clinicians. SETTING: Three obstetric units in New Zealand including tertiary and secondary care; public and private care, and research active and non-active units. PARTICIPANTS: Women undergoing a planned caesarean section from 35+0 to 39+6 weeks; local site researchers and clinicians. INTERVENTIONS: Two doses of 11.4 mg betamethasone or saline placebo. Questionnaires and focus group meetings. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome: trial recruitment rate of eligible women. SECONDARY OUTCOMES: trial recruitment by gestational age, site and delivery indication; proportion of babies who completed measurements of blood glucose concentrations as per protocol; overall incidence neonatal respiratory distress requiring >60 min of respiratory support; overall incidence of neonatal hypoglycaemia, and barriers and enablers to trial participation by participants, researchers and clinicians. RESULTS: The recruitment rate was 8.9% (88/987) overall and 11.2% (88/789) for those approached about the trial. Neonatal blood glucose concentrations were measured as per protocol in 87/92 (94.6%) babies. For potential participants, key enablers to participation were contributing to research, a feeling of relevance and a good understanding; key barriers were a lack of understanding and concerns over safety. For researchers and clinicians, themes representing enablers and barriers included relevance, communication and awareness, influences on women's decision-making, resource challenges and trial process practicalities. CONCLUSIONS: Some women are willing to participate in a randomised placebo-controlled trial of corticosteroids prior to a planned caesarean section birth at late preterm and term gestations. Participation in such a trial can be enhanced.

Prospective longitudinal study investigating predictors of childhood injuries from Growing Up in New Zealand cohort: study protocol.

BACKGROUND: Injury is one of the leading causes of mortality and morbidity worldwide and yet preventable and predictable. In New Zealand (NZ), unintentional injury is the leading cause of emergency department visits, hospitalisations and death among children, making it a significant public health concern. OBJECTIVE: To identify the factors that place young children in NZ at an increased risk of unintentional injury. METHODS: This study will investigate injuries among children from the prospective Growing Up in NZ birth cohort of 6853 children and their families. The primary outcome of interest is injury events where medical treatment was sought. The data sources include parental reports of child injury and Accident Compensation Corporation-NZ's no-fault injury compensation system-injury claims. The linked datasets will be utilised to examine the distribution of life course exposures and outcome data using descriptive statistics. A temporal multilevel model will then be developed to examine relationships between neighbourhood, child and family characteristics and injury from birth to 5 years of age for all children for whom parental consent to link data were obtained. DISCUSSION: The findings of this research will help to identify how the multiplicity of influences between children, family and their broader societal context acting across time affect their risk of experiencing a preschool injury. This information will provide an evidence base to inform context-relevant strategies to reduce and prevent childhood injuries.

Parental satisfaction with an advanced audiology-led triage service in paediatric ENT outpatient clinics.

OBJECTIVE: The advanced audiology-led service is designed to triage and manage children who are referred to Ear Nose and Throat (ENT) outpatient services with middle ear or hearing concerns. This service has resulted in shorter waiting times for children to receive ENT treatment, and improved ENT capacity. The aim of this study was to explore parental satisfaction with the advanced audiology-led ENT service and to determine if there were cultural or process factors affecting satisfaction. DESIGN: Prospective cross-sectional study using a modified Visit-Specific Satisfaction Questionnaire (VSQ-9) survey. STUDY SAMPLE: One hundred and thirteen parents of children consecutively attending a first appointment in the advanced audiology-led service recruited between October 2016 and October 2017. RESULTS: There were a total of 100 valid responses (rate of 88.5%). The survey showed high levels of satisfaction. Satisfaction scores were significantly higher for items related to interactions with the audiologist compared to items related to waiting times. There were no differences in satisfaction across cultural groups. Parents were equally satisfied with the service whether their child was managed independently by the audiologist or required another appointment for medical input. CONCLUSIONS: The advanced audiology-led service had high levels of satisfaction from parents attending with their children.

Safer Prescribing and Care for the Elderly (SPACE): a cluster randomised controlled trial in general practice.

BACKGROUND: Safer prescribing in general practice may help to decrease preventable adverse drug events (ADE) and related hospitalisations. AIM: To test the effect of the Safer Prescribing and Care for the Elderly (SPACE) intervention on high-risk prescribing of non-steroidal anti-inflammatory drugs (NSAIDs) and/or antiplatelet medicines and related hospitalisations. DESIGN & SETTING: A pragmatic cluster randomised controlled trial in general practice. Participants were patients at increased risk of ADEs from NSAIDs and/or antiplatelet medicines at baseline. SPACE comprises automated search to generate for each GP a list of patients with high-risk prescribing; pharmacist outreach to provide education and one-on-one review of list with GP; and automated letter inviting patients to seek medication review with their GP. METHOD: The primary outcome was the difference in high-risk prescribing of NSAIDs and/or antiplatelet medicines at 6 months. Secondary outcomes were high-risk prescribing for gastrointestinal, renal, or cardiac ADEs separately, 12-month outcomes, and related ADE hospitalisations. RESULTS: Thirty-nine practices were recruited with 205 GPs and 191 593 patients, of which 21 877 (11.4%) were participants. Of the participants, 1479 (6.8%) had high-risk prescribing. High-risk prescribing improved in both groups at 6 and 12 months compared with baseline. At 6 months, there was no significant difference between groups (odds ratio [OR] 0.99; 95% confidence intervals [CI] = 0.87 to 1.13) although SPACE improved more for gastrointestinal ADEs (OR 0.81; 95% CI = 0.68 to 0.96). At 12 months, the control group improved more (OR 1.29; 95% CI = 1.11 to 1.49). There was no significant difference for related hospitalisations. CONCLUSION: Further work is needed to identify scalable interventions that support safer prescribing in general practice. The use of automated search and feedback plus letter to patient warrants further exploration.

Impact of a voluntary industry code for advertising food to children and young people: an analysis of New Zealand television data.

OBJECTIVE: To evaluate the impact of the 2017 update to the voluntary Advertising Standards Authority (ASA) code for advertising food on children and young people's exposure to unhealthy food advertisements on New Zealand television. DESIGN: Audience ratings data were analysed for New Zealand children and young people's television viewing for eight random days prior to (June to August 2015) and following (October to December 2018) the code update, from 06.00 to midnight (864 h). Food advertisements were coded using three nutrient profiling models. The number of children and young people watching television each year was compared. SETTING: Three free-to-air New Zealand television channels. PARTICIPANTS: New Zealand children aged 5-18 years. RESULTS: Television viewer numbers decreased over the 3 years (P < 0·0001). The mean rate of unhealthy food advertising on weekdays was 10·4 advertisements/h (2015) and 9·5 advertisements/h (2018). Corresponding rates for weekend days were 8·1 and 7·3 advertisements/h, respectively. The percentage of food advertisements which were for unhealthy foods remained high (63·7 % on weekdays and 65·9 % on weekends) in 2018. The ASA definition of children's 'peak viewing time' (when 25 % of the audience are children) did not correspond to any broadcast times across weekdays and weekend days. CONCLUSIONS: Between 2015 and 2018, children and young people's television exposure to unhealthy food advertising decreased. However, almost two-thirds of all food advertisements were still unhealthy, and the updated ASA code excluded the times when the greatest number of children was watching television. Consequently, government regulation and regular monitoring should reflect the evolving food marketing environment.
