In New Zealand an advance directive can be either an oral statement or a written document. Such directives give individuals the opportunity to make choices about future medical treatment in the event they are cognitively impaired or otherwise unable to make their preferences known. All consumers of health care have the right to make an advance directive in accordance with the common law. When we consider New Zealand's rapidly ageing population, the fact that more people now live with and die of chronic rather than acute conditions, the importance given to respecting autonomous decision-making, increasing numbers of individuals who require long-term residential care, and financial pressures in the allocation of medical resources, there would seem to be a number of compelling reasons to encourage individuals to write or verbalise an advance directive. Indeed the promotion of advance directives is encouraged. However, caution should be exercised in promoting advance directives to older people, especially in light of several factors: ageist attitudes and stereotypes towards them, challenges in the primary healthcare setting, and the way in which advance directives are currently focused and formulated. This paper considers some of the specific challenges that need to be addressed if the promotion of advance directives are to improve outcomes of patient treatment and care near the end of life.

Objectives This paper aims to examine ethnic differences in financial barriers to access to prescriptionmedication in New Zealand. Methods Data from SoFIE-Health (wave 3), which is an add-on to the Statistics New Zealand-led longitudinal Survey of Family, Income and Employment (SoFIE) (N¼18 320), were analysed using logistic regression, adjusting for demographic, socioeconomic, health behaviour and health variables. Financial barriers to access to prescription items were measured by the following question: 'In the past 12 months, have there been any times when a doctor gave you a prescription, but you didn't collect one or more of these items because you could not afford the cost?'. Results The odds of deferring buying a prescription at least once during the preceding 12 months because they could not afford the cost of the prescription were greater for Maori and Pacific people than for NZ Europeans (OR 2.98, 95% CI 2.56 to 3.47 vs OR 3.52, 95% CI 2.85 to 4.35). Adjusting for potential confounders attenuated the ORs to 1.31 (95% CI 1.08 to 1.58) for Maori people and to 2.17 (95% CI 1.68 to 2.81) for Pacific people. Deferring buying medications because of cost was also associated with increased odds of poor self-reported health status, high/very high psychological stress and the presence of two or more comorbid conditions. Conclusion Ethnicity plays a critical role in facilitating or impeding access to primary health care. This suggests that policy measures to further reduce financial barriers to buying medication may improve access to care for everyone including Maori and Pacific people and may have positive health implications.

Objective: Recent studies suggest an association between the contextual attributes of neighbourhoods and the health status of residents. However, there has been a scarcity of studies that have directly measured the material characteristics of neighbourhoods theorised to have an impact on health and health inequalities. This paper describes the development of an innovative methodology to measure geographical access to a range of community resources that have been empirically linked to health. Geographical information systems (GIS) were applied to develop precise measures of community resource accessibility for small areas at a national scale. Design: Locational access to shopping, education, recreation, and health facilities was established for all 38 350 census meshblocks across New Zealand. Using GIS, distance measures were calculated from the population weighted centroid of each meshblock to 16 specific types of facilities theorised as potentially health related. From these data, indices of community resource accessibility for all New Zealand neighbourhoods were constructed. Results: Clear regional variations in geographical accessibility to community resources exist across the country, particularly between urban and rural areas of New Zealand. For example, the average travel time to the nearest food shop ranged from less than one minute to more than 244 minutes. Noticeable differences were also apparent between neighbourhoods within urban areas. Conclusions: Recent advances in GIS and computing capacity have made it feasible to directly measure access to health related community resources at the neighbourhood level. The construction of access indices for specific community resources will enable health researchers to examine with greater precision, variations in the material characteristics of neighbourhoods and the pathways through which neighbourhoods impact on specific health outcomes.

Objectives: This paper examines the cost effectiveness of the compulsory bicycle helmet wearing law (HWL) introduced in New Zealand on 1 January 1994. The societal perspective of costs is used for the purchase of helmets and the value of injuries averted. This is augmented with healthcare costs averted from reduced head injuries. Methods: Three age groups were examined: cyclists aged 5-12 years, 13-18 years, and ≥ 19 years. The number of head and non-head injuries averted were obtained from epidemiological studies. Estimates of the numbers of cyclists and the costs of helmets are used to derive the total spending on new bicycle helmets. Healthcare costs were obtained from national hospitalisation database, and the value of injuries averted was obtained directly from a willingness-to-pay survey undertaken by the Land Transport Safety Authority. Cost effectiveness ratios, benefit:cost ratios, and the value of net benefits were estimated. Results: The net benefit (benefit:cost ratios) of the HWL for the 5-12, 13-18, and ≥19 year age groups was $0.3m (2.6), -$0.2m (0.8), and -$1.5m (0.7) (in NZ $, 2000 prices; NZ $1.00 = US $0.47 = UK £0.31 approx). These results were most sensitive to the cost and life of helmets, helmet wearing rates before the HWL, and the effectiveness of helmets in preventing head injuries. Conclusions: The HWL was cost saving in the youngest age group but large costs from the law were imposed on adult (≥ 19 years) cyclists. [ABSTRACT FROM AUTHOR]

Background: Studies of the association between neighbourhood fragmentation and suicide have yielded varied results, and none has simultaneously adjusted for neighbourhood fragmentation, neighbourhood deprivation and individual-level factors. Method: A multilevel analysis of a 3-year cohort study was carried out using probabilistic linkage of census and mortality records, and two measures of neighbourhood fragmentation. A total of 2.8 million respondents to the 1996 New Zealand census were followed up for 3 years for mortality (1101 suicide deaths in the analysis), aged from 20 to 74 years at follow-up. Results: No consistent association was observed between either measure of neighbourhood social fragmentation and suicide, after controlling for individual-level confounders and neighbourhood deprivation. There was some evidence of a U-shaped relationship between neighbourhood fragmentation and suicide, especially for the Congdon(NZ) index. There was no evidence of an association for a nine-variable index that captured family-type variables as well as the usual attachment-type variables. Neighbourhood deprivation remained as an important predictor of suicide rates. Conclusion: This paper highlights the importance of understanding both the measure and the wider national context when considering neighbourhood effects on suicide. [ABSTRACT FROM AUTHOR]

Background: The Supermarket Healthy Options Project (SHOP) is a large, randomised, controlled trial designed to evaluate the effect of tailored nutrition education and price discounts on supermarket food purchases. A key objective was to recruit approximately equal numbers of Māori, Pacific and non-Māori, non-Pacific shoppers. This paper describes the recruitment strategies used and evaluates their impact on recruitment of Māori, Pacific and non-Māori, non-Pacific trial participants. Methods: Trial recruitment strategies included mailed invitations to an electronic register of supermarket customers; in-store targeted recruitment; and community-based recruitment. Results: Of the 1103 total trial randomisations for whom ethnicity was known, 247 (22%) were Māori, 101 (9%) Pacific and 755 (68%) were non-Māori, non-Pacific shoppers. Mailed invitations produced the greatest proportion of randomisations (73% vs 7% in-store, and 20% from community recruitment). However, in-store and community recruitment were essential to boost Māori and Pacific samples. The cost of mailout (NZ$40 (£14) per randomised participant) was considerably less than the cost of community and in-store recruitment (NZ$301 (£105) per randomised participant). Conclusions: The findings demonstrate considerable challenges and cost in recruiting indigenous and minority ethnic participants into intervention trials. Researchers and funding organisations should allocate more resources to recruitment of indigenous and minority populations than to recruitment of majority populations. Community recruitment and networks appear to be better ways to recruit these populations than passive strategies like mailouts. [ABSTRACT FROM AUTHOR]
