Effectiveness and cost of recruitment strategies for a community-based randomised controlled trial among rainwater drinkers

<p>Abstract</p> <p>Background</p> <p>Community-based recruitment is challenging particularly if the sampling frame is not easily defined as in the case of people who drink rainwater. Strategies for contacting participants must be carefully considered to maximise generalisability and minimise bias of the results. This paper assesses the recruitment strategies for a 1-year double-blinded randomised trial on drinking untreated rainwater. The effectiveness of the recruitment strategies and associated costs are described.</p> <p>Methods</p> <p>Community recruitment of households from Adelaide, Australia occurred from February to July 2007 using four methods: electoral roll mail-out, approaches to schools and community groups, newspaper advertising, and other media involvement. Word of mouth communication was also assessed.</p> <p>Results</p> <p>A total of 810 callers were screened, with 53.5% eligible. Of those who were eligible and sent further information, 76.7% were willing to participate in the study and 75.1% were enrolled. The target for recruitment was 300 households, and this was achieved. The mail-out was the most effective method with respect to number of households randomised, while recruitment via schools had the highest yield (57.3%) and was the most cost effective when considering cost per household randomised (AUD$147.20). Yield and cost effectiveness were lowest for media advertising.</p> <p>Conclusion</p> <p>The use of electoral roll mail-out and advertising via schools were effective in reaching households using untreated rainwater for drinking. Employing multiple strategies enabled success in achieving the recruitment target. In countries where electoral roll extracts are available to researchers, this method is likely to have a high yield for recruitment into community-based epidemiological studies.</p

Effectiveness of a school-community linked program on physical activity levels and health-related quality of life for adolescent girls

Background: This study evaluated the effectiveness of a school-community program on Health-Related Quality of Life (HRQoL; the primary outcome), physical activity (PA), and potential mediators of PA among adolescent girls living in low-socioeconomic rural/regional settings. Method: The study was a cluster-randomized controlled trial. Twelve communities with the requisite sports clubs and facilities were paired according to relevant criteria; one of each pair was randomly assigned to the intervention or control condition. Eight schools per condition were randomly selected from these communities and the intervention was conducted over one school year (2011). Female students in grades 7–9 in intervention schools participated in two 6-session PA units – a sport unit (football or tennis) and a recreational unit (leisure centre-based). These were incorporated into physical education (PE) curriculum and linked to PA opportunities for participation outside school. Students were surveyed at baseline and endpoint, self-reporting impact on primary and secondary outcome measures (HRQoL, PA) and PA mediators (e.g. self-efficacy). Linear mixed models for two-group (intervention, control) and three-group (completers, non-completers, control) analyses were conducted with baseline value, age and BMI as covariates, group as a fixed effect and school as random cluster effect. Results: Participants completing baseline and endpoint measures included: 358 intervention (baseline response rate 33.7%, retention rate 61.3%) and 256 control (14.1% and 84.0%). Adjustment for age and BMI made no substantive difference to outcomes, and there were no cluster effects. For HRQoL, after adjustment for baseline scores, the intervention group showed significantly higher scores on all three PedsQL scores (physical functioning: M ± SE = 83.9 ± 0.7, p = .005; psychosocial: 79.9 ± 0.8, p = .001; total score: 81.3 ± 0.7, p = .001) than the control group (80.9 ± 0.8; 76.1 ± 0.9 and 77.8 ± 0.8). The three-group analysis found intervention non-completers had significantly higher PedsQL scores (84.0 ± 0.8, p = .021; 80.4 ± 0.9, p = .003; 81.7 ± 0.8, p = .002;) than controls (80.9 ± 0.8, 76.1 ± 0.9 and 77.8 ± 0.8). There were no significant differences for any PA measure. Intervention completers had significantly higher scores than non-completers and controls for some mediator variables (e.g. self-efficacy, behavioural control). Conclusion: Positive outcomes were achieved from a modest school-community linked intervention. The school component contributed to maintaining HRQoL; students who completed the community component derived a range of intra-personal and inter-personal benefits

The cost-effectiveness of Australia\u27s active after-school communities program

The objective of this study was to assess from a societal perspective the cost-effectiveness of the Active After-school Communities (AASC) program, a key plank of the former Australian Government\u27s obesity prevention program. The intervention was modeled for a 1-year time horizon for Australian primary school children as part of the Assessing Cost-Effectiveness in Obesity (ACE-Obesity) project. Disability-adjusted life year (DALY) benefits (based on calculated effects on BMI post-intervention) and cost-offsets (consequent savings from reductions in obesity-related diseases) were tracked until the cohort reached the age of 100 years or death. The reference year was 2001, and a 3% discount rate was applied. Simulation-modeling techniques were used to present a 95% uncertainty interval around the cost-effectiveness ratio. An assessment of second-stage filter criteria (&quot;equity,&quot; &quot;strength of evidence,&quot; &quot;acceptability to stakeholders,&quot; &quot;feasibility of implementation,&quot; &quot;sustainability,&quot; and &quot;side-effects&quot;) was undertaken by a stakeholder Working Group to incorporate additional factors that impact on resource allocation decisions. The estimated number of children new to physical activity after-school and therefore receiving the intervention benefit was 69,300. For 1 year, the intervention cost is Australian dollars (AUD) 40.3 million (95% uncertainty interval AUD 28.6 million; AUD 56.2 million), and resulted in an incremental saving of 450 (250; 770) DALYs. The resultant cost-offsets were AUD 3.7 million, producing a net cost per DALY saved of AUD 82,000 (95% uncertainty interval AUD 40,000; AUD 165,000). Although the program has intuitive appeal, it was not cost-effective under base-case modeling assumptions. To improve its cost-effectiveness credentials as an obesity prevention measure, a reduction in costs needs to be coupled with increases in the number of participating children and the amount of physical activity undertaken.<br /

Depression in multicultural Australia: Policies, research and services

BACKGROUND: Depression is one of the leading causes of disability in Australia. The cultural and linguistic diversity of the Australian population poses a significant challenge to health policy development, service provision, professional education, and research. The purpose of this study is to explore the extent to which the fact of cultural and linguistic diversity has influenced the formulation of mental health policy, the conduct of mental health research and the development of mental health services for people with depression from ethnic minority communities. METHODS: The methods used for the different components of the study included surveys and document-based content and thematic analyses. RESULTS: Policy is comprehensive but its translation into programs is inadequate. Across Australia, there were few specific programs on depression in ethnic minority communities and they are confronted with a variety of implementation difficulties. The scope and scale of research on depression in Ethnic minority communities is extremely limited. CONCLUSION: A key problem is that the research that is necessary to provide evidence for policy and service delivery is lacking. If depression in Ethnic minority communities is to be addressed effectively the gaps between policy intentions and policy implementation, and between information needs for policies and practice and the actual research that is being done, have to be narrowed

Are women birthing in New South Wales hospitals satisfied with their care?

Abstract Background Surveys of satisfaction with maternity care among Australian women have been conducted using overnight inpatient surveys and dedicated maternity surveys in a number of Australian states and territories, however to date no information on satisfaction with maternity care has been published for women birthing in New South Wales. The aim of this study was to investigate the effects of pregnancy and birth characteristics, hospital location and type of care provision on patient satisfaction with hospital care at the time of birth. Results Analysis of responses from 5,367 obstetric patients completing overnight patient surveys between 2007 and 2011 revealed three quarters of women were satisfied with care provided in hospital. Compared with women who had previously given birth, first-time mothers were more likely to recommend their birth hospital to friends and family (60.5% versus 56.4%; P<0.05), less likely to have experienced differing messages from staff (44.8% vs 59.4%; P<0.001), and less likely to feel they had received sufficient information about feeding (58.8% vs 65.0%; P<0.001) and caring for their babies (52.4% vs 65.2%; P<0.001). Women having a caesarean birth were more likely to have a negative experience of differing messages from doctors and nurses than women giving birth vaginally (52.7% vs 44.3%; P<0.001). While metropolitan women were more likely to rate their birth hospital positively (76.0% vs. 71.3%; P<0.05) than their rural counterparts, rural women tended to rate the care they received (68.1% vs. 63.4%; P<0.05), and doctors (70.7% vs 61.1%; P<0.05) and nurses (73.5% vs. 66.9%; P<0.001) more highly than metropolitan women. Conclusions The overall picture of maternity care satisfaction in New South Wales is a positive one, with three quarters of women satisfied with care. The differences in care ratings among some subgroups of women (for instance, by parity and rurality) may assist in targeting allocation of resources to improve maternity satisfaction. Further resources could be dedicated to ensuring consistency and amount of information provided, particularly to first-time mothers.Australian Research Council Future Fellowship (#FT120100069)

Australia's insurance crisis and the inequitable treatment of self-employed midwives

Based upon a review of articles published in Australia's major newspapers over the period January 2001 to December 2005, a case study approach has been used to investigate why, when compared with other small business operators, including medical specialists, Australian governments have appeared reluctant to protect the economic viability of the businesses of self-employed midwives. Theories of agenda setting and structuralism have been used to explore that inequity. What has emerged is a picture of the complex of factors that may have operated, and may be continuing to operate, to shape the policy agenda and thus prevent solutions to the insurance problems of self-employed midwives being found

Effect of a chemical manufacturing plant on community cancer rates

BACKGROUND: We conducted a retrospective study to determine if potential past exposure to dioxin had resulted in increased incidence of cancer in people living near a former manufacturing plant in New South Wales, Australia. During operation, from 1928 to 1970, by-products of the manufacturing process, including dioxin and other chemical waste, were dumped into wetlands and mangroves, discharged into a nearby bay and used to reclaim land along the foreshore, leaving a legacy of significant dioxin contamination. METHODS: We selected 20 Census Collector Districts within 1.5 kilometres of the former manufacturing plant as the study area. We obtained data on all cases of cancer and deaths from cancer in New South Wales from 1972 to 2001. We also compared rates for some cancer types that have been associated with dioxin exposure. Based on a person's residential address at time of cancer diagnosis, or at time of death due to cancer, various geo-coding software and processes were used to determine which collector district the case or death should be attributed to. Age and sex specific population data were used to calculate standardised incidence ratios and standardised mortality ratios, to compare the study area to two comparison areas, using indirect standardisation. RESULTS: During the 30-year study period 1,106 cases of cancer and 524 deaths due to cancer were identified in the study area. This corresponds to an age-sex standardised rate of 3.2 cases per 1,000 person-years exposed and 1.6 deaths per 1,000 person-years exposed. The study area had a lower rate of cancer and deaths from cancer than the comparison areas. The case incidence and mortality due to lung and bronchus carcinomas and haematopoietic cancers did not differ significantly from the comparison areas for the study period. There was no obvious geographical trend in ratios when comparing individual collector districts to New South Wales according to distance from the potential source of dioxin exposure. CONCLUSION: This investigation found no evidence that dioxin contamination from this site resulted in increased cancer rates in the potentially exposed population living around the former manufacturing plant

From little things, big things grow: a local approach to system-wide maternity services reform in the absence of definitive evidence

For nearly two decades calls have been made to expand the role of midwives within maternity services in Australia. Although some progress has been made, it has been slow and, at system-wide level, limited. There are many barriers that prevent the expansion of midwifery-led services in Australia including funding arrangements for midwifery care, a lack of political will and resistance from powerful medical interest groups. The ongoing debate that exists about the evidence for the safety of midwifery-led care, particularly for the intrapartum phase, is likely to be an important reason why policy-makers are reluctant to implement system-wide reforms of maternity services

Australian health policy and end of life care for people with chronic disease: An analysis

End of life care for people with advanced chronic disease is a growing international imperative, with the majority of deaths in the world now related to chronic disease. The provision of care that meets the needs of people with advanced chronic disease must be guided by appropriate policy. The key policy areas impacting directly on end of life care are related to chronic disease, palliative care and, increasingly, aged care. This paper describes the outcomes of an audit of Australian chronic disease and end of life/palliative care policies. We identified that chronic disease health policies/strategies demonstrate a focus on prevention, early intervention and management, with scant recognition of end of life care needs. The majority assume that a referral to palliative care will address end of life care needs for people with chronic disease. By contrast, palliative care policies recognise the need for the incorporation of a palliative approach into advanced chronic disease care, but there are few connections between these two policy areas. Whilst palliative care policies intersect with carer and advance care planning policies, chronic disease policy does not. Key concerns requiring consideration when developing policy in this area are discussed and possible policy options identified.Teresa Burgess, Annette Braunack-Mayer, Gregory B. Crawford, Justin Beilb
