RESUMO
PURPOSE: In Aotearoa me Te Waipounamu (New Zealand; NZ) there are considerable inequities in health status and outcomes for Maori, the Indigenous peoples of NZ. It is therefore important that the health status and preferences of Maori are specifically considered in healthcare policy and decision making. This paper describes the health-related quality of life of 390 Maori adults who took part in the NZ EQ-5D-5L valuation study. METHODS: Responses on the five dimensions of the EQ-5D-5L were dichotomised into "no problems" and "any problems", summarised and disaggregated by age group. Mean preference weights were reported by age group and overall. Mean utility values (calculated by applying each participant's preference weights to their EQ-5D-5L profile) were summed and respective means and standard deviations reported by age, chronic disease status and disability. RESULTS: The EQ-5D-5L dimensions with the highest proportion of participants reporting any problems were pain/discomfort (61.5%) and anxiety/depression (50%). The most commonly-reported chronic disease was mental illness/distress (24.6%). Anxiety/depression ranked as the most important dimension, with usual activities, the least important. The mean utility value was 0.83 with the lowest value (0.79) found in the 18-24 and 45-54 age groups. For participants with at least one chronic disease the mean utility value was 0.76 compared to 0.91 for those with none. CONCLUSION: To reduce inequities experienced by Maori it is crucial that the health status of Maori and the values Maori place on health-related quality of life are properly understood. This can only be achieved using Maori-specific data.

INTRODUCTION: New Zealand's Smokefree 2025 goal aims to greatly decrease the availability of tobacco. One option is to cease the sale of tobacco from convenience stores. However, tobacco companies and retail trade associations oppose this move and have argued that customers who purchase tobacco drive footfall and spend more than non-tobacco customers. The aim of this study is to test the validity of industry claims about the importance of tobacco to convenience stores. METHODS: During November and December 2019, immediate postpurchase surveys were undertaken with customers on exit from a random sample of 100 convenience stores in two New Zealand cities. We estimated the mean number of items purchased, including tobacco and non-tobacco items, and mean expenditure on non-tobacco items. RESULTS: Of the 3399 transactions recorded, 13.8% included tobacco, of which 8.3% comprised tobacco only and 5.5% included tobacco and non-tobacco items. The mean number of transactions containing both tobacco and non-tobacco items was 1.98, and 1.87 for those containing non-tobacco items only. Customers who purchased tobacco and non-tobacco items spent on average NZ$6.99 on non-tobacco items, whereas customers who purchased non-tobacco items only, spent on average NZ$5.07. CONCLUSIONS: Our results do not support claims that tobacco drives one-quarter of footfall into stores or that customers who purchase tobacco spend almost twice as much as non-tobacco customers. Combined purchases of tobacco and non-tobacco items constituted 5.5% of transactions; the impact on a store's profitability of removing tobacco sales is unknown and could be the focus of future research.

OBJECTIVES: To derive New Zealand (NZ) population norms for the EQ-5D-5L and to examine the association between participants' sociodemographic characteristics and their health-related quality of life. METHODS: Data from the 2018 NZ EQ-5D-5L valuation study (n = 2468) were used. Each participant's 5-digit profile was converted to a single utility value using their personal value set. The profiles, mean utility values, and mean EuroQol visual analog scale (EQ-VAS) scores were summarized by dimension and disaggregated by age group and gender. Multivariable logistic and Tobit regressions were used to investigate the association between participants' sociodemographic characteristics and the EQ-5D-5L dimensions, utility values, and EQ-VAS scores. RESULTS: The mean utility value was 0.847 and the mean EQ-VAS score was 74.8. Of the 3125 possible EQ-5D-5L profiles, 25 profiles represented the current health status of the majority of participants (78%). The odds of having problems with anxiety or depression was greatest for people aged 18 to 24 years and decreased with age. People with a long-term disability or chronic illness had greater odds of problems on all dimensions and lower (poorer) utility values and EQ-VAS scores. Age, ethnicity, employment status, long-term disability, and chronic illness were associated with utility. CONCLUSION: EQ-5D-5L population norms were derived for the NZ population using the personal value sets of 2468 participants. Consistent with other countries' population norms, EQ-5D-5L utility values and EQ-VAS scores were associated with age, employment status, long-term disability, and chronic illness. These norms will support resource allocation decision making and help in understanding the health-related quality of life of the NZ population.

AIM: Expert recommendations for child/adolescent obesity include extensive investigation for weight-related comorbidities, based on body mass index (BMI) percentile cut-offs. This study aimed to estimate the cost of initial investigations for weight-related comorbidities in children/adolescents with obesity, according to international expert guidelines. METHODS: The annual mean cost of investigations for weight-related comorbidities in children/adolescents was calculated from a health-funder perspective using 2019 cost data obtained from three New Zealand District Health Boards. Prevalence data for child/adolescent obesity (aged 2-14 years) were obtained from the New Zealand Health Survey (2017/2018), and prevalence of weight-related comorbidities requiring further investigation were obtained from a previous New Zealand study of a cohort of children with obesity. RESULTS: The cost of initial laboratory screening for weight-related comorbidities per child was NZD 28.36. Based on national prevalence data from 2018/2019 for children with BMI greater than the 98th percentile (obesity cut-off), the total annual cost for initial laboratory screening for weight-related comorbidities in children/adolescents aged 2-14 years with obesity was estimated at NZD 2,665,840. The cost of further investigation in the presence of risk factors was estimated at NZD 2,972,934. CONCLUSIONS: Investigating weight-related comorbidities in New Zealand according to international expert guidelines is resource-intensive. Ways to further determine who warrants investigation with an individualised approach are required.

BACKGROUND: Total hip and knee arthroplasties (THA/TKA) are clinically effective but high cost procedures. The aim of this study is to perform a cost-effectiveness analysis of THA and TKA in the New Zealand (NZ) healthcare system. METHODS: Data were collected from 713 patients undergoing THA and 520 patients undergoing TKA at our local public hospital. SF-6D utility values were obtained from participants preoperatively and 1-year postoperatively, and deaths and any revision surgeries from patient records and the New Zealand Joint Registry at minimum 8-year follow-up. A continuous-time state-transition simulation model was used to estimate costs and health gains to 15 years. Quality-adjusted life years (QALYs), treatment costs, and incremental cost-effectiveness ratios (ICERs) were calculated to determine cost effectiveness. ICERs below NZ gross domestic product (GDP; NZ$60 600) and 0.5 times GDP per capita were considered "cost effective" and "highly cost effective" respectively. RESULTS: Cumulative health gains were 2.8 QALYs (THA) and 2.3 QALYs (TKA) over 15 years. Cost effectiveness improved from ICERs of NZ$74,400 (THA) and NZ$93,000 (TKA) at 1 year to NZ$6000 (THA) and NZ$7500 (TKA) at 15 years. THA and TKA were cost effective after 2 years and highly cost effective after 3 years. QALY gains and cost effectiveness were greater in patients with worse preoperative functional status and younger age. CONCLUSION: THA and TKA are highly cost-effective procedures over longer term horizons. Although preoperative status and age were associated with cost effectiveness, both THA and TKA remained cost effective in patients with less severe preoperative scores and older ages.

INTRODUCTION: Arguments regarding the importance of tobacco to convenience stores could impede the adoption of tobacco retail reduction policies. Although trade associations argue tobacco constitutes two-thirds of convenience store sales and drives footfall, few studies have tested these claims. We therefore examined the prevalence and characteristics of tobacco purchases at convenience stores in Dunedin, New Zealand. METHODS: We conducted a postpurchase survey at 20 convenience stores, each visited for three 60 min intervals over a 4-week period. We used descriptive statistics to determine proportions and 95% CIs of transactions that contained tobacco and those that contained only non-tobacco items. We estimated the mean number of items purchased, the mean number of non-tobacco items purchased and mean expenditure on non-tobacco items. RESULTS: Fourteen per cent of transactions contained tobacco (n=95/679); of those, 64% comprised tobacco only. Only 5% of all transactions included both tobacco and non-tobacco products. The mean number of non-tobacco items purchased was 1.9 for transactions containing only non-tobacco products and 1.7 for transactions containing both tobacco and non-tobacco products. After excluding the cost of tobacco, people who purchased tobacco and non-tobacco products spent on average $5.11 on non-tobacco items, whereas people who purchased only non-tobacco items spent on average $6.85. CONCLUSIONS: Tobacco products constitute a small proportion of items purchased from Dunedin convenience stores and are typically not purchased with non-tobacco items. Our findings are inconsistent with arguments that most small retailers rely on tobacco sales.

OBJECTIVES: The use of multicriteria decision analysis for health technology prioritization depends on decision-making criteria and weights according to their relative importance. We report on a methodology for determining criteria and weights that was developed and piloted in New Zealand and enables extensive participation by members of the general population. METHODS: Stimulated by a preliminary ranking exercise that involved prioritizing 14 diverse technologies, six focus groups discussed what matters to people when thinking about technologies that should be funded. These discussions informed the specification of criteria related to technologies' benefits for use in a discrete choice survey designed to generate weights for each individual participant as well as mean weights. A random sample of 3218 adults was invited to participate. To check test-retest reliability, a subsample completed the survey twice. Cluster analysis was performed to identify participants with similar patterns of weights. RESULTS: Six benefits-related criteria were distilled from the focus group discussions and included in the discrete choice survey, which was completed by 322 adults (10% response rate). Most participants (85%) found the survey easy to understand, and the survey exhibited test-retest reliability. The cluster analysis revealed that participant weights are related more to idiosyncratic personal preferences than to demographic and background characteristics. CONCLUSIONS: The methodology enables extensive participation by members of the general population, for whom it is both acceptable and reliable. Generating weights for each participant allows the heterogeneity of individual preferences, and the extent to which they are related to demographic and background characteristics, to be tested.

BACKGROUND: Subsequent injury (SI) is a major contributor to disability and costs for individuals and society. AIM: To identify modifiable risk factors predictive of SI and SI health and disability outcomes and costs. OBJECTIVES: To (1) describe the nature of SIs reported to New Zealand's no-fault injury insurer (the Accident Compensation Corporation (ACC)); (2) identify characteristics of people underaccessing ACC for SI; (3) determine factors predicting or protecting against SI; and (4) investigate outcomes for individuals, and costs to society, in relation to SI. DESIGN: Prospective cohort study. METHODS: Previously collected data will be linked including data from interviews undertaken as part of the earlier Prospective Outcomes of Injury Study (POIS), ACC electronic data and national hospitalisation data about SI. POIS participants (N=2856, including 566 Maori) were recruited via ACC's injury register following an injury serious enough to warrant compensation entitlements. We will examine SI over the following 24â months for these participants using descriptive and inferential statistics including multivariable generalised linear models and Cox's proportional hazards regression. DISCUSSION: Subsequent Injury Study (SInS) will deliver information about the risks, protective factors and outcomes related to SI for New Zealanders. As a result of sourcing injury data from New Zealand's 'all injury' insurer ACC, SInS includes people who have been hospitalised and not hospitalised for injury. Consequently, SInS will provide insights that are novel internationally as other studies are usually confined to examining trauma registries, specific injuries or injured workers who are covered by a workplace insurer rather than a 'real-world' injury population.

BACKGROUND: In 2010, the New Zealand (NZ) government introduced an annual 10% tobacco excise tax increase. We examined retailers' adherence to recommended retail prices (RRP), and whether the RRP included the full tax increase. METHODS: We collected price data on three British American Tobacco (BAT) factory-made cigarette brands, (premium, mainstream, and budget), and one roll-your-own tobacco brand before and after the 2014 tax increase from a sample of tobacco retailers. We examined price increases in each tobacco brand and compared these with the RRP. The extent to which the excise tax increases had been included in the RRP since 2010 was estimated using data sourced from the Ministry of Health and NZ Customs. FINDINGS: The median increase in price from before to after the tax change was only 3% for the budget brand (461 retailers). This contrasted with the median of 8% for the premium brand (448 retailers), and 11% for both mainstream and roll-your-own brands (471 and 464 retailers, respectively). While many retail outlets made changes according to the RRP set by BAT, several did not comply. Our analyses suggest BAT may be undershifting excise tax on the budget brand, and overshifting tax on brands in other price partitions. CONCLUSIONS: Tobacco companies do not appear to be increasing the RRPs of budget brands in line with tobacco excise tax increases. The increasing price differential between budget brands, and mainstream and premium brands may undermine cessation and impede realisation of New Zealand's Smokefree 2025 goal.

OBJECTIVE: The aim of this study was to compare past New Zealand immunization strategies with the New Zealand coronavirus disease 2019 (COVID-19) immunization roll-out. METHODS: Using the READ document analysis method, 2 New Zealand immunization strategies (for influenza and measles) were analyzed for how the disease, context, vaccine supply and demand, ethical principles (equity, individual autonomy, and maximizing benefits), and the Treaty of Waitangi impacted the immunization programs. The findings were compared with the ongoing COVID-19 mass immunization program in New Zealand, as of October 15, 2021. RESULTS: Several themes common to the case-studies and the COVID-19 pandemic were identified including the importance of equity, obligations under the Treaty of Waitangi, ethical mandates, and preparedness. CONCLUSIONS: Future emergency planning should integrate learnings from other infectious disease responses and immunization programs to avoid repeating mistakes and to create better health outcomes. This study has provided a basis for ongoing research into how an appropriate immunization plan can be developed that incorporates ethical values, the Treaty of Waitangi (in the NZ context), and evidence-based research to increase trust, equity, health, and preparedness for future outbreaks.

The SF-6D health descriptive system and its second version published in 2020, the SF-6Dv2, is used worldwide for valuing health-related quality of life (HRQoL) for economic evaluation and measuring patient-reported health outcomes. In this study, a valuation tool was developed and applied to create a social value set, comprising 18,750 health state values, for the SF-6Dv2 for New Zealand (NZ). This tool was adapted and extended from the one used to create a social value set for the EQ-5D-5L, a simpler health descriptive system with fewer dimensions and health states. The tool implements the PAPRIKA method, a type of adaptive discrete choice experiment, and a binary search algorithm to identify health states worse than dead and has extensive data quality controls to ensure the validity and reliability of the social value set derived from participants' personal value sets. The tool, accompanied by a short introductory video designed specifically for the SF-6Dv2, was distributed via an online survey to a large representative sample of adult New Zealanders in June-July 2022. The tool's data quality controls enabled participants who failed to understand or sincerely engage with the valuation tasks to be identified and excluded, resulting in the participants being pared down to a sub-sample of 2985 'high-quality' participants whose personal value sets were averaged for the social value set. These results, including participants' positive feedback, demonstrate the feasibility and acceptability of using the tool to value larger health descriptive systems such as the SF-6Dv2. Having successfully created an SF-6Dv2 social value set for NZ, the valuation tool can be readily applied to other countries, used to generate personal value sets for personalised medicine and adapted to create value sets for other health descriptive systems.

BACKGROUND: In the early 2020s, nearly half of New Zealand adults reported that cost of treatment had prevented them from accessing dental care, with higher rates among Maori, Pasifika and individuals living in the most deprived areas. Unaffordable dental care may be explained by a rise in dental service fees over time relative to personal income, as documented in New Zealand between 1978 and 1993. However, there have been no contemporary estimates in New Zealand of how the affordability of dental care has changed. The aims of this study were to analyse the change in dental treatment fees and the personal income of New Zealanders from 1978 to 2023 and to explore differences in affordability of dental care by ethnicity. METHODS: Average fees for dental treatments were sourced from surveys completed by practising New Zealand dentists. Earnings (from 1978) and personal income data (full population from 2000 and by ethnicity from 2008) were sourced from Statistics NZ and NZ Official Yearbooks. Inflation-adjusted changes in average fees, weekly personal earnings and income were calculated as a percentage change from 1978 levels for fees and earnings and from 2000 for personal income. RESULTS: For the five dental treatments with data available from 1978 to 2023, fees increased in the range of 75%-236%, while earnings increased by 46% over the same period. Fees for other treatments (with data available from 1981 to 2009) similarly increased and mostly surpassed changes in earnings. From 2008 to 2023 the overall increase in personal income (about 21% across all ethnic groups) kept pace with the rising cost of most treatments. However, due to persistent income inequalities, in 2023, Maori and Pasifika would need to spend a higher proportion of their weekly income (approximately 16% and 23% respectively) to receive the same dental treatments as NZ Europeans. CONCLUSIONS: Fees for dental treatments have risen markedly in recent decades, more sharply than the price of other goods and services.
RESUMO
Introduction Few mandatory community-based attachments for postgraduate year two doctors (PGY2s) in Aotearoa New Zealand are hosted in general practices, due to space, time and remuneration barriers. Aim This study aimed to explore the costs, barriers and enablers to general practices of hosting PGY2s. Methods A cost analysis for four general practices beginning to host PGY2s was undertaken, including time spent supervising and supporting PGY2s, revenue impact including subsidies and cost of providing clinical space. Interviews with these practices and seven experienced PGY2 host practices were conducted and analysed thematically. Results The estimated mean cost of hosting PGY2s excluding room cost was NZ$4907 per 13-week placement (range $890-$9183), increasing to $13 727 per placement (range $5750-$24 715) when room rental was included. Four themes were identified: working within a small business model; a new learning environment for PGY2s; providing positive experiences for the PGY2s; the relationship between practices and district hospitals that employed the PGY2s, including job sizing. Discussion Tension exists between the small business model of general practice and providing positive experiences for PGY2s in a new learning environment. Guidance and support structures for PGY2 hosting should be developed nationally, and communication and cooperation between practices and employing hospitals needs improvement. Out-of-hours work should be included in community-based attachments so PGY2s' remuneration is consistent. General practice teams are willing to be part of creating a sustainable workforce. However, the time taken to host and costs of providing training in primary care are barriers. There is urgent need to increase funding to general practices for hosting PGY2s.

OBJECTIVE: To identify and describe (1) which health-related quality of life (HRQoL) measures have been used with Indigenous children/youth (aged 8-17 years) within the Pacific Rim; and (2) studies that refer to Indigenous health concepts in the use of child/youth HRQoL measures. DESIGN: A scoping review. DATA SOURCES: Ovid (Medline), PubMed, Scopus, Web of Science and CINAHL were searched up until 25 June 2020. ELIGIBILITY CRITERIA: Eligible papers were identified by two independent reviewers. Eligible papers were written in English, published between January 1990 and June 2020 and included an HRQoL measure used in research with Indigenous child/youth populations (aged between 8 and 17 years) in the Pacific Rim region. DATA EXTRACTION AND SYNTHESIS: Data extracted included study characteristics (year, country, Indigenous population, Indigenous sample size, age group), HRQoL measure characteristics (generic or condition-specific measure, child or adult measure, who completed the measure(s), dimensions, items and response scale of measure) and consideration of Indigenous concepts (created for Indigenous population, modified for Indigenous population, validated for Indigenous population, reliability in Indigenous populations, Indigenous involvement, reference to Indigenous theories/models/frameworks). RESULTS: After removing duplicates, 1393 paper titles and abstracts were screened, and 543 had full-text review for eligibility. Of these, 40 full-text papers were eligible, reporting on 32 unique studies. Twenty-nine HRQoL measures were used across eight countries. Thirty-three papers did not acknowledge Indigenous concepts of health, and only two measures were specifically created for use with Indigenous populations. CONCLUSIONS: There is a paucity of research investigating HRQoL measures used with Indigenous children/youth and a lack of involvement of Indigenous peoples in the development and use of HRQoL measures. We strongly recommend explicit consideration of Indigenous concepts when developing, validating, assessing and using HRQoL measures with Indigenous populations.

BACKGROUND: The COVID-19 pandemic has highlighted personal protective equipment (PPE) supply, distribution, and disposal issues worldwide. Calls to conserve PPE stocks and increase supply resulted in the rapid development of potential disinfection methods, with the possibility of improvements in medical waste reduction. However, how receptive health-care workers are to PPE reuse remains unknown. We aimed to examine the views of health-care workers who used PPE during the first COVID-19 wave in Aotearoa New Zealand, in relation to acceptability of PPE disinfection and reuse. METHODS: In this multi-methods survey, health-care workers in New Zealand, were invited via a multimodal recruitment strategy to complete a survey regarding use of PPE during the first COVID-19 wave. Gender question options were male, female, gender diverse, or prefer not to say. Demographic differences in self-reported PPE reuse and acceptability were examined. The survey included closed (single-response, multi-response, ranking, and Likert-scale questions) and open-text questions. Any open-text comments were analysed with thematic analysis. The survey was built and deployed using Qualtrics software. FINDINGS: 1411 health-care workers completed the survey between Oct 7 and Nov 30, 2020. 1397 participants had gender data available (1140 [82%] female and 257 [18%] male) and 995 (74%) of 1347 were of New Zealand European ethnicity. PPE reuse was common and reported by 628 (45%) of the 1411 participants, with 396 (63%) of the 628 reporting reusing PPE multiple times in 1 day. Acceptability of the concept of PPE disinfection for potential reuse was high overall (1196 [85%] of 1411) but varied depending on the type of PPE. Thematic analysis confirmed that PPE reuse was already occurring and respondents recognised the potential benefits of reduced medical wastage and increased PPE supply. Important caveats for consideration included the availability of scientific evidence, level of negotiated risk, and trust in the organisation undertaking PPE disinfection, with clear communication about decontamination processes being crucial to acceptability. INTERPRETATION: PPE reuse occurred frequently during the first wave of COVID-19 in New Zealand. Although support for the disinfection of PPE for reuse was high, the success of any future programmes to reuse PPE will require meaningful engagement and clear communication with health-care workers. Further research into PPE disinfection safety and logistics is warranted, alongside the development of standard operating procedures and clearly communicated policies for the end user, should this more sustainable health-care practice be planned for adoption in certain settings. FUNDING: New Zealand Ministry of Business, Innovation and Employment (COVID-19 Innovation Acceleration Fund) and the Medical Assurance Society Foundation.

OBJECTIVES: In Aotearoa New Zealand (NZ), integration across the healthcare continuum has been a key approach to strengthening the health system and improving health outcomes. A key example has been four regional District Health Board (DHB) groupings, which, from 2011 to 2022, required the country's 20 DHBs to work together regionally. This research explores how this initiative functioned, examining how, for whom and in what circumstances regional DHB groupings worked to deliver improvements in system integration and health outcomes and equity. DESIGN: We used a realist-informed evaluation study design. We used documentary analysis to develop programme logic models to describe the context, structure, capabilities, implementation activities and impact of each of the four regional groupings and then conducted interviews with stakeholders. We developed a generalised context-mechanisms-outcomes model, identifying key commonalities explaining how regional work 'worked' across NZ while noting important regional differences. SETTING: NZ's four regional DHB groupings. PARTICIPANTS: Forty-nine stakeholders from across the four regional groupings. These included regional DHB governance groups and coordinating regional agencies, DHB senior leadership, Maori and Pasifika leadership and lead clinicians for regional work streams. RESULTS: Regional DHB working was layered on top of an already complex DHB environment. Organisational heterogeneity and tensions between local and regional priorities were key contextual factors. In response, regional DHB groupings leveraged a combination of 'hard' policy and planning processes, as well as 'soft', relationship-based mechanisms, aiming to improve system integration, population health outcomes and health equity. CONCLUSION: The complexity of DHB regional working meant that success hinged on building relationships, leadership and trust, alongside robust planning and process mechanisms. As NZ reorients its health system towards a more centralised model underpinned by collaborations between local providers, our findings point to a need to align policy expectations and foster environments that support connection and collegiality across the health system.

OBJECTIVE: The aim of this study was to determine which growth indicator (weight, weight-for-length, BMI) and time frame (6- or 12-month intervals between 0 and 24 months) of rapid infant weight gain (RIWG) best predicted obesity risk and body composition at 11 years of age. METHODS: RIWG (increase ≥0.67 z scores between two time points) was calculated from weight and length/height at birth, 0.5, 1, 1.5, and 2 years. The predictive value of each measure and time frame was calculated in relation to obesity (BMI ≥95th percentile) and body fat (fat mass index [FMI], dual-energy X-ray absorptiometry scan) at 11 years. RESULTS: The sensitivity (1.5% to 62.1%) and positive predictive value (12.5% to 33.3%) of RIWG to predict obesity varied considerably. Having obesity at any time point appeared a stronger risk factor than any indicator of RIWG for obesity at 11 years. Obesity at any age during infancy consistently predicted a greater FMI of around 1.1 to 1.5 kg/m2 at 11 years, whereas differences for RIWG were inconsistent. CONCLUSIONS: A simple measure of obesity status at a single time point between 6 and 24 months of age appeared a stronger risk factor for later obesity and FMI than RIWG assessed by any indicator, over any time frame.

INTRODUCTION: Evidence from multiple countries suggests poisons centres create value in several ways including the provision of expert clinical advice, decreased hospital length of stay and triage of exposures enabling safe management without further medical utilisation. Data specific to the New Zealand context are lacking. Therefore, this study aimed to estimate one aspect of poison centre value, namely the potential savings to the health system related to triage advice provided by the New Zealand National Poisons Centre (NZNPC). METHODS: A prospective survey was conducted over a 2-week period where eligible NZNPC callers - who were advised their exposure did not require further medical assessment - were asked what alternative action they would have taken in the hypothetical absence of the NZNPC. The potential cost savings associated with the alternative actions respondents would have taken were calculated using publicly available information and extrapolated to the population level using annual NZNPC call numbers for 2019. RESULTS: Among 554 eligible callers, 399 were recruited to participate and 396 provided responses. The single most common alternative action was "search the Internet" (54/396, 14%). In-person medical assessment would have been sought by 25% (100/396), and 39% (154/396) would have called an alternative provider within the healthcare system. The estimated cost associated with alternative actions for the study period was NZ$25,637. When extrapolated to the 2019 year, the potential savings from avoided healthcare utilisation was NZ$1,061,551. CONCLUSION: In 2019, in the absence of NZNPC triage advice, a conservatively estimated NZ$1,061,551 would have been spent on healthcare related to poisoning exposures that were appropriate for management without further medical utilisation. It is important to note that this estimate is only one aspect of the total value created by the NZNPC and is consistent with findings of value from other poisons centres internationally.

AIMS: To examine if differences exist between injured Maori and non-Maori in accessing and receiving support from the Accident Compensation Corporation (ACC) for treatment and rehabilitation of subsequent injuries. METHODS: This cohort study utilised participants' self-reported data from the Prospective Outcomes of Injury Study, and ACC claims data. RESULTS: Approximately one-third of Maori (32%) and non-Maori (35%) who self-reported a subsequent injury had no associated ACC claim. Statistically significant differences in this outcome (i.e., self-reported subsequent injury but no ACC claim) were found between Maori and non-Maori when comparing across occupation type and severity of participants' sentinel injuries. Few differences were observed between Maori and non-Maori in the percentages of ACC claims accepted that compensated various treatments and supports; this was similar for average compensation amounts provided. CONCLUSIONS: Maori and non-Maori who received support from ACC for a sentinel injury prior to sustaining another injury appear to have received equitable ACC compensation for the treatment and rehabilitation of the subsequent injury with two potential exceptions. Further research is needed to determine how generalisable these findings are. Establishing routine systems for collecting data about the support needed, treatment pathways and outcomes once accessing ACC support is vital to ensure positive and equitable injury outcomes for Maori.

Increased demand for single-use personal protective equipment (PPE) during the COVID-19 pandemic has resulted in a marked increase in the amount of PPE waste and associated environmental pollution. Developing efficient and environmentally safe technologies to manage and dispose of this PPE waste stream is imperative. We designed and evaluated a hydrothermal deconstruction technology to reduce PPE waste by up to 99% in weight. Hydrothermal deconstruction of single-use PPE waste was modelled using experimental data in Aspen Plus. Techno-economic and sensitivity analyses were conducted, and the results showed that plant scale, plant lifetime, discount rate, and labour costs were the key factors affecting overall processing costs. For a 200 kg/batch plant under optimal conditions, the cost of processing PPE waste was found to be 10 NZD/kg (6 USD/kg), which is comparable to the conventional practice of autoclaving followed by landfilling. The potential environmental impacts of this process were found to be negligible; meanwhile, this practice significantly reduced the use of limited landfill space.
